[Embodiment 1]

Hereinafter, embodiments of the present invention will be described below based on FIGS. 1 to 13.

<Data management system>

First, the data management system 100 according to this embodiment will be described using FIG. 2. FIG. 2 is a diagram showing an example of the data management system 100 according to this embodiment.

The data management system 100 is a simple environmental measurement system that: (1) measures the concentration of a specific substance in a specific environment (that is, contained in a specific space) using a measuring device; (2) manages various kinds of results including the measurement results on the Internet Measure related data; (3) Display various data managed on the network to the user terminal. In order to realize this processing, the data management system 100 includes a test reagent group 1, a measuring device 2, a portable information terminal 3, a server 4 (storage device), and a personal computer (PC, Personal Computer) 5. Furthermore, the portable information terminal 3 and the PC 5 are equivalent to the user terminal.

In this embodiment, for example, a specific environment (specific space) is described using a water environment (including a drain water), a river, or a sea as a water environment in a factory, a groundwater treatment plant, a research institute, a household, or agriculture. . That is, in this embodiment, water quality measurement is performed by measuring the concentration of various substances contained in water. Furthermore, the data management system 100 is not limited to this, and can also be used to measure the state of various environments such as the atmosphere and soil.

In the data management system 100, the measurement device 2 is communicably connected to the portable information terminal 3 using short-range wireless communication. In this embodiment, Bluetooth (registered trademark) Low Energy (BLE) can be used for short-range wireless communication, but other Bluetooths can also be used. Specifications, ZigBee (registered trademark), etc. When Bluetooth Low Energy is used for short-range wireless communication, power consumption of data communication between the measuring device 2 and the portable information terminal 3 can be suppressed. In addition, the measuring device 2 is not limited to the above-mentioned short-range wireless communication, as long as it uses wireless communication to establish a communicable connection with the portable information terminal 3.

At the same time, in the data management system 100, the server 4 establishes a communicable connection with the portable information terminal 3 and the PC 5 through a network line. As for this network line, various lines such as an Internet line, a wireless LAN (Local Area Network) such as Wi-Fi (registered trademark), a WAN (Wide Area Network), and a mobile phone line can be used. At the same time, the server 4 only needs to be able to establish a communicable connection with the portable information terminal 3 and the PC 5, and may also be connected in a wired manner.

The measuring device 2 measures the absorbance (transmittance) of the water (that is, the substance to be measured in the water) by irradiating light to the water containing the measurement target of the reagent 11 in the detection reagent group 1. The measuring device 2 compares the absorbance after the measurement with a standard line for the measurement target substance to calculate the concentration of the measurement target substance contained in the measurement target water. That is, the standard line data is used to determine the concentration of a substance. Simultaneously, the calculated substance concentration (measurement result) is transmitted to the measuring device 2 using a short-range wireless communication, and is transmitted from the portable information terminal 3 to the server 4 through a network line. At the same time, various data including measurement results managed by the server 4 can be transmitted to the PC 5 as necessary. Thereby, not only the measurement result can be managed by the measuring device 2, but also the measurement result can be managed by the portable information terminal 3 and the server 4. At the same time, users can view the measurement results on the portable information terminal 3 or PC5. This means that the user can easily confirm the measurement result (ie, the state of the environment) with a terminal other than the measurement device 2. At the same time, users (that is, various users who are not limited to the tester) with the authority to use the data management system 100 can easily confirm the measurement results through the portable information terminal 3 or PC5.

At the same time, the standard line data is managed in the server 4 and transmitted to the portable information terminal 3 through the network line. Thereby, the standard line data can also be managed in the portable information terminal 3. At the same time, in the standard line data managed by the portable information terminal 3, at least a part selected by the user is transmitted to the measuring device 2 using short-range wireless communication. Thereby, it is possible to prevent standard line data (that is, unnecessary standard line data) corresponding to a measurement item that is not selected by the user as a measurement target from being stored (saved) in the measuring device 2. With this, for example, in the case of updating or adding the standard line, while the storage capacity of the measuring device 2 can be used efficiently, it is possible to eliminate the need for the user to remove all standard line data including unnecessary standard line data It is troublesome to select a specific item among all the corresponding measurement items.

Hereinafter, the configuration of the data management system 100 according to this embodiment will be described with reference to a test reagent group 1, a measuring device 2, a portable information terminal 3, a server 4, and a PC 5.

<Test reagent group>

Next, the detection reagent group 1 according to this embodiment will be described using FIG. 3. FIG. 3 (a) is a diagram showing the appearance of the test reagent group 1, and FIG. 3 (b) is a diagram showing the inside of the test reagent group 1.

The test reagent group 1 prepares a substance as a measurement item each time, and includes a reagent 11 for detecting the substance and a comparative color paper 12 for analogy of the measurement value for visual confirmation of the measurement result. In this embodiment, it is to provide the user with a check because the test reagent 11 shown in FIG. 3 (b) is packaged in a box as shown in FIG. 3 (a) and the comparison color paper 12 for the analogy measurement value is provided. Test drug group 1. Examples of the substance to be measured include, for example, COD, PO ₄ , NH ₄ , NO ₃ and the like contained in industrially discharged water. The above substances are not limited to this. For example, all substances obtained in the environment of the measurement object (that is, substances that can be obtained as the measurement object). In order to obtain the measurement results for these substances, A test reagent group 1 for each of the reagent 11 and the comparative color paper 12 for analogy measurement values can be prepared.

For example, when COD is contained in the water to be measured, the reagent 11 for detecting COD is colored by containing the water. The degree of color development of the reagent 11 differs depending on the proportion of COD contained in water. By analogy, the measured value for comparison color paper 12 discretely displays the concentration value (unit: mg / L) corresponding to the degree of color development measured in advance. Therefore, the user can confirm the approximate value of the concentration value by comparing the test reagent 11 after color development with the comparison color paper 12 for analogy measurement values. However, in this embodiment, since the substance concentration measurement is performed in the measuring device 2, the detection reagent group 1 does not need to include the comparative color paper 12 for analogy measurement values.

<Measurer>

Next, the measuring device 2 according to this embodiment will be described using FIG. 1 and FIG. 4. FIG. 1 is a block diagram showing details of the measuring device 2, the portable information terminal 3, and the server 4 included in the data management system 100 of this embodiment. Meanwhile, Fig. 4 (a) is a diagram showing the appearance of the measuring device 2; Fig. 4 (b) is a plan view showing the measuring device 2; Fig. 4 (c) is a diagram showing a measuring cup 6;

For example, receiving and instructing to switch screens such as pairing with a short-range wireless communication terminal, setting the date and time, contrast adjustment of the measurement display 24, and the like. At the same time, it receives a confirmation screen for viewing past measurement results, and receives measurements for setting from the portable information terminal 3. Instruction to switch the group selection screen selected in the group consisting of item, measurement area and measurement point. Here, the measurement area refers to an area where the measurement is performed, and the measurement point refers to a place where the measurement is actually performed in the area. At the same time, an instruction to switch the measurement mode is received. In this embodiment, the measurement mode includes, for example, an automatic measurement mode for measuring one measurement item, a manual measurement mode for measuring a plurality of measurement items after selection, and an absorbance measurement mode for absorbance measurement. .

The up and down keys receive instructions from the user. For example, they receive instructions for switching the content displayed on the measurement display 24 during various settings or when viewing measurement results. The power button receives an instruction from a user, for example, an instruction to switch on or off a power source (not shown) of the measuring device 2. The measurement button receives a user instruction, for example, a measurement start instruction or a measurement interrupt instruction. The zero-adjustment button receives an instruction from the user. For example, it receives a zero-adjustment start instruction for starting zero-adjustment (correction to zero).

The measurement display 24 displays a measurement mode, a measurement item, a measurement area, a measurement result, and the like, and is configured by, for example, an LCD (Liquid Crystal Display).

The measurement unit 27 is used to measure the concentration of the substance to be measured. The measurement unit 27 includes a recessed portion that can accommodate the measurement cup 6, a light source 22 (see FIG. 1), and a light receiving unit 23 (see FIG. 1).

The light source 22 emits light toward the concave portion, and is configured by, for example, a light emitting diode (LED). When adjusting to zero or measuring the concentration of the substance, the measuring cup 6 containing water as the measurement target is inserted into the recess, and the light emitted from the light source 22 is irradiated to the water as the measurement target.

In this embodiment, in order to measure plural measurement items, the light source 22 is provided with a red LED capable of emitting red light (for example, the wavelength range of a peak is 610 nm or more and less than 750 nm) and a green light (for example, a wavelength range of a peak Green LEDs above 495nm and less than 570nm, and capable of emitting blue light (e.g., the wavelength range of the peak is above 450nm and small It is composed of a chip of three light sources, such as a blue LED at 495 nm. In order to improve the measurement accuracy, the peak wavelength of red light is preferably around 615 nm, the peak wavelength of green light is preferably around 525 nm, and the peak wavelength of blue light is preferably around 470 nm. In addition, as long as the measurement of a plurality of measurement items can be achieved, the type of the light source is not limited to the above. In other words, the measuring device 2 may be a multi-item absorbance photometer capable of measuring a plurality of measurement items.

The light receiving unit 23 receives the light emitted from the light source 22 and passes through the recessed portion, and measures the light intensity (light receiving intensity) after the light is received. When the concentration of the substance is adjusted or measured by zeroing, the light emitted from the light source 22 and transmitted through the water to be measured is received.

The cover 28 is a cover that protects the measurement unit 27. When the cover 28 is opened due to zero adjustment or when measuring the concentration of the substance, the measuring unit 27 is opened and the measuring cup 6 as shown in FIG. 4 (c) can be inserted. The measurement cup 6 contains water as a measurement object, and is inserted into the measurement unit 27 when the measurement cup is adjusted to zero or the concentration of the measurement substance is measured. The measuring cup 6 has a shape capable of being inserted into the recessed portion, and a mark line ML indicating the amount of water as a measurement target is formed on the surface thereof.

Meanwhile, as shown in FIG. 1, the measuring device 2 includes a measuring device control section 25 and a measuring device storage section 26.

The measuring instrument control unit 25 controls each component constituting the measuring instrument 2 by executing a control program, for example. The measuring instrument control unit 25 reads and executes a program stored in the measuring instrument storage unit 26 by, for example, a temporary storage unit (not shown) constituted by a RAM (Random Access Memory) or the like, calculates measurement results, and transmits and receives data. Various processing. The measuring instrument control unit 25 mainly includes a data transmission / reception unit 251, a data processing unit 252, a measurement processing unit 253, and a measurement display control unit 254.

The data transmission and reception unit 251 performs data communication with the portable information terminal 3 using short-range wireless communication. The data transmission and reception unit 251 is controlled by the data processing unit 252. For example, the data displaying the measurement result, the measurement date and time, and the version of the measuring device 2 are transmitted to the portable information terminal 3, or the data transmission and receiving unit 251 receives the measurement items and measurements selected by the user from the portable information terminal 3 and displayed Area-related, measurement point, and item-related data of response time, and standard line data corresponding to the measurement item. The reaction time is set to a sufficient time based on the substance of each measurement item and the termination of the reaction between the substance and the reaction reagent 11.

The data processing unit 252 processes various data based on, for example, a user instruction received by the measurement operation unit 21. For example, the data processing unit 252 includes a measurement processing unit 253.

In order to zero-adjust or set each output value (incident light intensity) of each measurement item in advance, the measurement processing unit 253 outputs light from the light source 22 based on a user instruction received from the measurement operation unit 21. This output value is set for each of the red LED, the green LED, and the blue LED of the light source 22. At the same time, the absorbance (= log ₁₀ (received light intensity / incident light intensity)) is calculated based on the received light intensity data showing the received light intensity from the light receiving unit 23, the received light intensity, and the incident light intensity. At the same time, the measurement processing unit 253 calculates the concentration of the substance as the measurement result of the substance based on the calculated absorbance and the standard line data of the substance corresponding to the current measurement target, and stores it in the measuring unit storage unit 26. At this time, the measurement processing unit 253 refers to the standard line data corresponding to the substance (measurement item) to be measured stored in the measurement unit storage unit 26. The substance to be measured can be selected by the user's instruction, or it can be the substance to be measured the previous time. Meanwhile, in the present embodiment, the measurement processing unit 253 calculates the measurement result to the second decimal place (decomposition energy; 0.01 mg / L), but it is not limited to this.

In this way, since the measurement result is calculated using the measuring device 2 in the present embodiment, the measurement result can be obtained without relying on the feeling and judgment of the user. This means that by analogy with users When the measurement value is obtained by visually comparing the color paper 12 with the measurement value, the measurement result can be obtained simply and accurately.

Meanwhile, when the data processing unit 252 is capable of data communication with the portable information terminal 3 (when it is determined that data communication with the portable information terminal 3 is established), the data processing receiving unit 251 is controlled by the control data transmission and reception unit 251, and the measurement processing unit 253 The measurement result in the measuring device storage section 26 is transmitted to the portable information terminal 3. Meanwhile, in the case of the above-mentioned data communication, the data processing section 252 stores the item-related data and the standard line data received from the portable information terminal 3 in the measuring device storage section 26.

The measurement display control unit 254 controls display on the measurement display 24. For example, the measurement display control unit 254 displays the measurement results and the like calculated by the measurement processing unit 253 on the measurement display 24 based on the screen instructed by the user under the control of the data processing unit 252.

The measuring instrument storage unit 26 stores various control programs and the like executed by the measuring instrument control unit 25. For example, the measuring instrument storage unit 26 is composed of a nonvolatile storage device such as a hard disk or a flash memory. The measuring instrument storage unit 26 stores the measurement result measured by the measurement processing unit 253 in each measurement item. Meanwhile, the measurement results are stored corresponding to the measurement date and time, the measurement area, and the measurement point. At the same time, in the measuring device storage section 26, the measurement item selected by the user using the portable information terminal 3, the standard line data corresponding to the measurement item, and the reaction time between the substance of the measurement item and the reagent 11 are determined. Store accordingly.

In this embodiment, the measurement result is transmitted from the measuring device 2 to the portable information terminal 3 and is managed in the portable information terminal 3 or the server 4. Therefore, it is not necessary to store and manage a large number of measurement results in the measurement device 2. In the measuring device storage section 26, a user can immediately confirm that the user can use the measuring device 2 To a certain extent, until the data communication with the portable information terminal 3 is established, it is only necessary to store the measurement results sufficient for storage. In the present embodiment, the measuring device storage section 26 can store measurement results of about several tens (for example, about 50). When the maximum value of the measurement result is exceeded, the oldest measurement result is overwritten by the latest measurement result.

<Measurement method>

Next, a method for measuring the concentration of a substance will be described using FIG. 5. (A)-(f) is a figure which shows an example of a measurement method. Here, a measurement method when the automatic measurement mode is set will be described.

As shown in FIG. 5 (a), first, the user puts water (test water) as a measurement target into the measurement cup 6 and reaches the marking line ML. Thereafter, as shown in FIG. 5 (b), the user turns on the power of the measuring device 2 through the measuring operation section 21, sets the measuring cup 6 containing the test water in the recess of the measuring device 27, and closes the seal. Cover 28. After that, when the measurement processing unit 253 receives a user's instruction to perform the zero adjustment through the measurement operation unit 21, the zero adjustment is started. When the zero reset adjustment is completed, the measurement processing unit 253 notifies the measurement display control unit 254 of the final message, and the measurement display control unit 254 displays a screen showing the completion of the zero reset adjustment on the measurement display 24. At this time, the measurement display control unit 254 uses the portable information terminal 3 to display a screen for selecting a measurement item selected by the user on the measurement display 24. When the user selects a measurement item, the measurement processing unit 253 reads the measurement item, the standard line data corresponding to the measurement item, and the response time corresponding to the measurement item.

Next, as shown in FIG. 5 (c), the user stretches the string attached to the front end of the test tube containing the reagent 11 for the measurement item substance, and holds the test tube by holding it as shown in FIG. 5 (d). The air inside the test tube is extruded from the hole formed by stretching the string. After that, as shown in FIG. 5 (e), with the test tube being held, the tip of the test tube is inserted into the test water stored in the measurement cup 6, and the test water is sucked into the test tube. At this time, the user presses down the measurement operation section A measurement button of 21 (meaning, if a user instruction to start measurement is received through the measurement operation unit 21), the measurement processing unit 253 starts calculation of a response time corresponding to a measurement item selected by the user.

As shown in (f) of FIG. 5, the user returns the test water containing the test reagent 11 (the test water after the substance of the selected measurement item reacts with the test reagent 11) inside the test tube to the measurement cup 6 and measures the The cup 6 is provided in the recessed portion of the measurement portion 27, and the lid 28 is closed. When the calculation of the reaction time is completed, the measurement processing unit 253 emits light from the light source 22. After the light penetrates the test water containing the reagent 11, the light is received by the light receiving unit 23, and the light receiving unit 23 transmits the light receiving intensity data showing the light receiving intensity of the transmitted light to the measurement processing unit 253. The measurement processing unit 253 calculates the absorbance of the test water inside the measurement cup 6 based on the light intensity shown in the incident light intensity and light intensity data (that is, the absorbance of the substance to be measured contained in the test water), and based on the absorbance. Calculate the concentration of the substance with the standard line data of the measurement item.

The measurement processing unit 253 stores the concentration as a measurement result in the measuring device memory unit 26 and transmits a measurement completion notification to the measurement display control unit 254. When the measurement display control unit 254 receives the notification, the measurement item is displayed on the measurement display 24 together with the measurement result.

In addition, when a plurality of measurement items are selected in the manual measurement mode, the steps shown in FIGS. 5 (a) to (f) are repeated for each measurement item, and the concentration of the substance showing each measurement item is calculated and displayed in the measurement. Display 24. Meanwhile, in the case of the absorbance measurement mode, the measurement processing unit 253 performs the absorbance measurement of the test item test water after performing the above-mentioned zero adjustment.

<About the light source 22>

Generally, in a light-emitting diode, the light-emitting wavelength is shifted from a specific light-emitting wavelength according to the magnitude of the current. When the light source 22 is used as the light-emitting diode, in order to correct the above-mentioned offset, the following process may be performed in the manufacturing process of the measuring device 2.

Specifically, an optical filter that penetrates a specific emission wavelength is arranged in front of the light source 22, and the size of the power source applied to the light source 22 is controlled so that light from the light source 22 passes through the optical filter. That is, the magnitude of the current when penetrating the optical filter is set to the value of the current applied to the light source 22.

At the same time, in addition to the constant-current circuit for the light source 22, the measuring device 2 also includes an electronic volume. When the magnitude of the current is adjusted, the signal potential obtained by the light receiving circuit constituting the light receiving unit 23 also changes with the adjustment. Because the gain of the amplifier in the light receiving circuit is adjusted according to the electronic volume, the change of the signal potential is suppressed, and the signal potential can be adjusted to a desired value.

Thereby, the manufactured measuring device 2 can suppress the wavelength shift of the light emitted from each light source 22. Therefore, it is possible to suppress the absorbance error caused by the wavelength shift and improve the yield. At the same time, because the occurrence of errors can be suppressed, the measurement accuracy can also be improved. Furthermore, the effect of not having to prepare a plurality of standard line data for one measurement item (Reagent 11) because of considering the wavelength deviation is achieved.

<Server>

Next, the server 4 according to this embodiment will be described using FIG. 1 and FIG. 6. FIG. 6 is a diagram showing an example of the measurement data base T1; (b) is a diagram showing an example of the measurement item data base.

As shown in FIG. 1, the server 4 includes a server control unit 41 and a server storage unit 42.

The server control unit 41 controls each component constituting the server 4 by executing a control program, for example. The server control unit 41 is a temporary storage unit configured by a RAM (Random Access Memory). The storage unit (not shown) reads and executes programs stored in the server storage unit 42 and performs various processes such as storage processing of measurement data including measurement results, and data transmission and reception processing. The server control unit 41 mainly includes a data transmission and reception unit 411 and a data processing unit 412.

The data transmission and reception unit 411 performs data communication with the portable information terminal 3 or the PC 5 through a network line. The data transmission and reception unit 411 is controlled by the data processing unit 412, for example, to transmit to the portable type the project data in which the plural measurement items are displayed and the plural standard line data corresponding to the project data stored in the server storage unit 42. The information terminal 3 or the data transmission and reception unit 411 receives measurement data including a measurement result from the portable information terminal 3.

At the same time, when the standard line data is updated or added, the data transmission and reception unit 411 transmits the standard line data to the portable information terminal 3 together with the update notification data described later. At the same time, the data transmission and reception unit 411 transmits the received measurement data to the PC 5 so that the user can view it.

The data processing unit 412 performs processing on various data while controlling the data transmission and reception unit 411. For example, the data processing unit 412 stores and manages the measurement data received by the data transmission and reception unit 411 in the server storage unit 42.

At the same time, the data processing section 412 manages the standard line data corresponding to the respective measurement items that can be measured by the measuring device 2, and manages them in the server storage section 42. For example, based on a user instruction, when updating the standard line data of the measurement item that has been stored, the data processing section 412 stores the updated standard line data in the server storage section 42 related to the measurement item. At the same time, when a measurement item that can be measured by the measuring device 2 is added based on a user instruction, the data processing unit 412 stores the measurement item and the standard line data corresponding to the measurement item in the server storage unit 42. Next, when new standard line data is added, or at least one of the standard line data is updated, the data processing unit 412 generates update notification data that displays the update or addition.

At the same time, when the data processing unit 412 updates the measurement processing software (application) for setting the measuring device 2 or viewing the measurement results based on a user's instruction, it generates update data displaying the updated content. At this time, software update notification data showing that the measurement processing software has been updated is also generated, and is transmitted to the portable information terminal 3 together with the updated data through the data transmission and reception section 411. In addition, when new standard line data is added or updated, it can also be used as updated measurement processing software and generate software update notification data.

The server storage unit 42 stores various control programs and the like executed by the server control unit 41. For example, the server storage unit 42 is composed of a nonvolatile storage device such as a hard disk or a flash memory. The server storage unit 42 stores various data such as standard line data corresponding to each measurement item, and reception of measurement data from the portable information terminal 3. For example, these data are managed in a measurement database T1 shown in FIG. 6 (a) and a measurement item database T2 shown in FIG. 6 (b).

In the measurement database T1, for example, the measurement date and time, measurement area (area), measurement point (point), measurement item, measurement result (measurement value) are managed, and the user (for example, the measurement person) , User information of the measuring instrument 2, measuring instrument information of the measuring instrument 2 itself, measuring instrument version showing the measuring instrument 2 version for measurement, and standard line version. The measurement date and time, measurement area, measurement point, measurement item, measurement result, measurement device information, and measurement device version are transmitted from the portable information terminal 3 as measurement data. At this time, the user name is also transmitted. In the standard line version, the latest version of the standard line data stored in the measurement item database T2 corresponding to the measurement items contained in the measurement data is stored. The data processing unit 412 is sequentially stored in the measurement database T1 each time the data transmission and reception unit 411 receives the measurement data.

In the measurement item database T2, the reagent 11, the reaction time of each measurement item substance and the reagent 11, and the standard line information are stored so as to correspond to the measurement items that can be measured in the measuring device 2. material. When additional measurement items are added, the above-mentioned information about the new measurement items is stored in the measurement item database T2. At the same time, in the case of updating the standard line data, the updated standard line data and the standard line version are stored. The updated standard line data and standard line version can cover the standard line data and standard line version before the update, and the updated standard line data and standard line version can also be stored separately.

<Portable Information Terminal>

Next, a portable information terminal according to this embodiment will be described with reference to FIG. 1. As shown in FIG. 1, the portable information terminal 3 is capable of data communication with the measuring device 2 and the server 4. For example, the portable information terminal 3 can be implemented by using a multifunctional mobile phone such as a smart phone or a tablet computer. The portable information terminal 3 includes a terminal display 31 (display screen), a terminal operation section 32, a terminal control section 33, and a terminal storage section 34.

For example, the terminal display 31 displays various images including the measurement processing image MA in the measurement processing software provided to the portable information terminal 3 (see FIG. 9). Meanwhile, for example, when the measurement processing software is started, the terminal display 31 displays a selection screen of a measurement item or a measurement result. The terminal display 31 is configured by, for example, an LCD (Liquid Crystal Display).

The terminal operation unit 32 receives user instructions for various images. For example, the terminal operation unit 32 is configured by a touch panel that is provided overlapping the terminal display 31. At the same time, when the measurement processing software is started, the terminal operation unit 32 receives input of a measurement area, a measurement point, and a user name as a user instruction. At the same time, in this state, when a selection screen of a measurement item is displayed, an instruction to select a measurement item is received. Furthermore, the current position of the portable information terminal 3 obtained by the data processing unit 332 using the GPS function of the portable information terminal 3 is used as a measurement area and a measurement point.

For example, the terminal control unit 33 executes a control program to control each component constituting the portable information terminal 3. The terminal control section 33 uses, for example, RAM (Random Access A temporary storage unit (not shown), such as a memory), reads and executes the program stored in the terminal storage unit 34, and performs various processes such as calculation processing to generate measurement data, and data transmission and reception processing. The terminal control unit 33 mainly includes a data transmission and reception unit (data acquisition unit, data transmission unit) 331, a data processing unit 332, and a display control unit 333.

The data transmission and reception unit 331 uses short-range wireless communication to perform data communication with the measuring device 2 and also performs data communication with the server 4 through a network line. The data transmission and reception unit 331 is controlled by the data processing unit 332, and transmits, for example, item-related data including a measurement item, a measurement area, a measurement point, and a response time selected by the user, and standard line data corresponding to the measurement item to The measuring device 2 or the data transmitting and receiving unit 331 receives data from the measuring device 2 which displays the measurement result, the measurement date and time, and the version of the measuring device 2. At the same time, for example, the data transmission and reception unit 331 transmits and stores the measurement data including the measurement result received by the measurement device 2 with the user name and stores it in the server 4, and receives (acquires) the management data from the server 4 in the server. Item 4 displays various data such as item data of the measurement item, and plural standard line data corresponding to the measurement item. In this embodiment, the measurement data is based on the data transmission and reception unit 331 acquiring the measurement result from the measurement device 2 as an opportunity, and transmitting the measurement result to the server 4.

At the same time, when the standard line data is updated or added, the data transmission and receiving unit 331 receives the update notification data (or software update notification data) and the standard line data from the server 4 together.

The data processing unit 332 controls the data transmission and reception unit 331 and the display control unit 333, and processes various data. For example, the data processing unit 332 generates measurement data including measurement results received by the data transmission and reception unit 331, and stores and manages the data in the terminal storage unit 34 while transmitting the data to the server 4 through the data transmission and reception unit 331.

At the same time, the data processing unit 332 manages the plurality of standard line data from the server 4 in the terminal storage unit 34 so as to correspond to the measurement items that can be measured in the measurement unit 2. In the case where the standard line data is updated by the server 4, the data processing unit 332 stores the received updated standard line data in the terminal storage unit 34 through the data transmission and receiving unit 331. At the same time, when a new measurement item is added to the server 4, the received data of the item on which the measurement item is displayed and the standard line data corresponding to the measurement item are stored in the terminal storage portion 34 through the data transmission and receiving section 331.

In addition, the data processing unit 332 transmits the received update notification data to the display control unit 333, and also generates an update notification image for notifying the user of the update or addition in the display control unit 333. When the measurement processing software is updated, the data processing unit 332 generates, on the display control unit 333, a software update notification image that notifies the user that the update has been performed.

At the same time, the data processing unit 332 performs processing based on user instructions (for example, various user instructions for measurement processing software) received by the terminal operation unit 32. For example, when the operation of displaying the measurement processing image MA (see FIG. 9) of the measurement processing software is touched, the data processing unit 332 starts the measurement processing software. In addition, for example, when receiving a measurement item selection instruction, the data processing unit 332 displays a measurement item selection screen on the display control unit 333 and specifies a measurement item selected by the user. The specified measurement item is a measurement item corresponding to the actual measurement target of the user. Meanwhile, for example, when receiving a display instruction of the measurement result, the data processing unit 332 displays a measurement result screen displaying the measurement result on the display control unit 333.

At the same time, the data processing section 332 stores the measurement area and the measurement point selected by the user in the terminal storage section 34 corresponding to a given measurement item. Next, the data processing unit 332 transmits the item-related data and the standard line data stored in the terminal storage unit 34 to the measuring device 2 through the data transmission and reception unit 331. Thereby, a group selection screen of the measuring device 2 can be generated.

In addition, the data processing section 332 determines to establish data communication with the measuring device 2 using the short-range wireless communication. At the same time, the data processing unit 332 performs the date and time management of the portable information terminal 3, and transmits the date and time data showing the date and time of the portable information terminal 3 to the measuring device through the data transmission and receiving unit 331 based on the user's instruction. 2. Thereby, the data processing unit 252 of the measuring device 2 matches the date and time of the measuring device 2 with the date and time on which the date and time data is displayed. In other words, the data processing unit 332 can synchronize the date and time of the measuring device 2 with the date and time of the portable information terminal 3.

The display control unit 333 controls display on the terminal display 31. For example, the display control unit 333 is controlled by the data processing unit 332 and displayed on the measurement display 24 based on a screen or the like instructed by the user.

For example, the display control unit 333 displays the following three on the measurement display 24: (1) A selection screen for selecting a measurement item corresponding to an actual measurement object for the user, the selection screen including a plurality of measurement items, and the plurality of measurement items It is selected by the user from a plurality of measurement items in which the item data obtained from the server 4 is displayed; (2) a measurement result screen including the measurement results obtained from the measurement device 2; (3) in the data transmission and reception section 331 When the update notification data is obtained, an update notification image (or software update image) for performing update notification. Furthermore, the software update notification image may be the same as the update notification image.

When the update notification image is displayed, when the user starts the measurement processing software, the data processing unit 332 selects an updated or added measurement item, and displays the measurement item on the terminal display 31 through the display control unit 333. This enables the user to select the measurement item. At the same time, after the selection, data related to the measurement item (item-related data and standard line data) is transmitted to the measuring device 2, so it is not necessary to update the standard line data and the like in the measuring device 2.

The terminal storage unit 34 stores various control programs and the like executed by the terminal control unit 33. For example, the terminal storage unit 34 is composed of a nonvolatile storage device such as a hard disk or a flash memory. The terminal storage unit 34 stores standard line data corresponding to each measurement item acquired from the server 4 and various data such as measurement data received from the measurement device 2. The terminal storage unit 34 is the same as the server 4 and, for example, manages these data in the measurement database T1 and the measurement item database T2. When a user selects a measurement item, for example, each inputted user name is managed in the measurement item database T2.

At the same time, if the standard line data can be displayed on the measuring device 2, the user can confirm the standard line data (version of the standard line data) used in the measuring device 2. Therefore, it is useful from the viewpoint of transmitting the standard line data to the measuring device 2.

At the same time, when the standard line data is updated or added, when the standard line data is stored in the measuring device using a storage medium, all the standard line data corresponding to the measurable measurement items are stored in the measuring device. The storage capacity of the measuring device is increased. On the other hand, in the portable information terminal 3, because the wireless communication is used to transmit the standard line data corresponding to the measurement item selected by the user to the measuring device 2, if the update notification data and the new standard line data are obtained, it is the same as As in the case of using a storage medium, the storage capacity of the measuring device 2 does not increase.

[Embodiment 2]

Based on Fig. 1 and Fig. 14, another embodiment of the present invention will be described below. In addition, for convenience of description, components having the same functions as those described in the foregoing embodiment are denoted by the same reference numerals and descriptions thereof will be omitted.

The data processing unit 252 transmits the measurement frequency data showing the number of measurement times to the portable information terminal 3 through the data transmission and reception unit 251, and the measurement frequency is related to the item data of the measurement items to be measured.

In the portable information terminal 3 of the present embodiment, the data transmission and reception unit 331 acquires data on the number of measurements from the measurement device 2 using short-range wireless communication. The data processing unit 332 determines whether the number of measurement times indicated by the obtained number of measurement times data exceeds a threshold value for the number of measurement times of each measurement item. When the data processing unit 332 determines that the threshold value is exceeded, the display control unit 333 generates an order notification image and prompts the user to perform additional ordering of the reagent 11 for the measurement item after counting the number of measurements. In other words, the display control unit 333 performs an order notification for prompting the user to add the order.

At the same time, in the server 4 of the present embodiment, the data processing unit 412 manages purchase history data indicating the purchase time of the reagent 11 for measuring each measurement item (that is, for measuring the concentration of a substance). For example, the data processing unit 412 manages the purchase history data based on the reagent database T3 shown in FIG. 14. The data processing unit 332 of the portable information terminal 3 may also generate the order notification image to the display control unit 333 based on the purchase history data.

In the reagent database T3 of this embodiment, at least the reagent 11, the purchase history, and the user name are managed for each measurement item. For example, the seller of the test drug 11 registers the sold test drug 11, the sales day (purchase date), and the purchaser on the server 4, and the server 4 manages the purchase history of the test drug 11.

The data transmission / reception unit 331 acquires the purchase history data (data showing the purchase date) of the reagent 11 purchased by the user from the server 4 at a specific timing. The data processing unit 332 determines whether or not the sales date of the purchase history data acquired from the server 4 is not before a specific number of days from the current date. When it is determined that the sales day is before a certain number of days, the display control unit 333 generates an order notification image that prompts the user to order the test 11 further. In other words, the display control unit 333 performs an order notification for prompting the user to perform the additional order.

Furthermore, the user can also manage the purchase history by inputting the purchased reagent 11, the purchase date, and the user name through the terminal operation unit 32 of the portable information terminal 3.

Therefore, it becomes possible for the user to order additional reagent 11 at an appropriate timing, and it is possible to prevent the situation where the necessary reagent 11 is lacking when measuring the concentration of the substance.

[Embodiment 3]

Based on Fig. 1 and Fig. 14, another embodiment of the present invention will be described below. In addition, for convenience of explanation, for components having the same functions as those described in the foregoing embodiment, The same symbols are used and explanations thereof are omitted. In the present embodiment, a configuration of the reagent suitability determination processing (determination processing) performed by the measuring device 2 will be described.

In the reagent database T3 of this embodiment, at least the reagent 11 and the reagent suitability determination data are managed for each measurement item. The reagent suitability determination data is used by the tester 2 to determine whether the test reagent 11 used in the tester 2 is suitable as the test reagent 11 to be measured in the tester 2. In other words, the test suitability determination data is an identification code for determining test 11. For example, the test suitability determination data is attached to a box of the package test reagent group 1, a test tube inserted with the test reagent 11, or a comparison color paper 12 for analogy measurement. At this time, the materials for determining suitability of the test drug are indicated by a bar code, a QR code (registered trademark), or a hologram. It is possible to use test suitability determination data common to all measurement items (test reagent 11), or to use different test suitability determination data for each test item. At the same time, the test suitability information can be encrypted.

At the same time, in the measuring device 2 of the present embodiment, the test suitability determination data supplied to the test reagent group 1 is connected to a reading device (not shown). When measuring the concentration of the substance, the data processing unit 252 of the measuring device 2 reads the barcode attached to the detection reagent group 1 on a reading device, analyzes the read information, and obtains the information supplied to the detection reagent group 1. Information on the suitability of the test drug. At the same time, the data processing unit 252 transmits the item data showing the measurement items to be measured to the portable information terminal 3.

In the portable information terminal 3 of this embodiment, if the data transmission and reception unit 331 acquires the item data from the measuring device 2, it transmits a data transmission request for determining whether the test suitability of the test item corresponds to the measurement item on which the item data is displayed to the servo.器 4。 4. In the server 4 of this embodiment, if the data transmission and reception section 411 obtains a transmission request, the data processing section 412 transmits the data for determining the suitability of the test reagent corresponding to the measurement item of the transmission request to the data transmission and reception section 411 through Portable information terminal 3. In the portable information terminal 3, if the data processing unit 332 obtains the test drug through the data transmission and reception unit 331, The determination data is transmitted to the measuring device 2 through the data transmission / reception unit 331 along with the instruction to start the determination of the suitability of the test reagent together with the determination data of the suitability of the test reagent.

In the measuring device 2, if the data processing unit 252 obtains the above-mentioned instruction and the suitability determination of the test reagent through the data transmission and reception unit 251, the suitability determination of the test reagent is performed. Specifically, the data processing unit 252 compares the test suitability determination data obtained with the test suitability determination data obtained from the reading device, and determines whether the two test suitability determination data determine whether Consistent.

In the case where the determination of the suitability of the two reagents is consistent, the data processing unit 252 starts the measurement of the substance concentration. On the other hand, when the determination of the suitability of the two reagents does not agree with each other, the data processing unit 252 displays an error that cannot be measured on the measurement display control unit 254. At the same time, an inconsistent message is transmitted to the portable information terminal 3, and an error display can also be performed on the portable information terminal 3. Furthermore, when the reading device cannot read the test suitability determination data, an error display is also performed.

The reading device can be stored in the measuring device 2. At the same time, in order to allow the user to perform operations such as reading the barcode, the data processing unit 332 may perform the reading operation while urging the user to perform the operation such as reading the barcode, and only when the two reagents described above are suitable for If the discrimination data match, the measurement processing unit 253 starts the concentration measurement of the substance.

At the same time, the tester 2 may be provided with item data indicating the suitability of the test reagent supplied to the test reagent group 1. At this time, the data transmission and reception unit 251 transmits the item data included in the test suitability determination data obtained by reading the barcode or the like to the portable information terminal 3. As described above, the data transmitting and receiving unit 251 receives the test suitability determination data corresponding to the item data from the server 4 through the portable information terminal 3.

Then, in a case where the two test reagents are determined to be incompatible with each other, the data processing unit 252 transmits the message to the portable information terminal 3. When the determination result is obtained, the data processing unit 332 of the portable information terminal 3 may not perform a process for the user to select a measurement item. In other words, the data processing unit 332 may not perform at least any of the following three processes: (1) The data transmission and reception unit 331 is from the server Acquisition of standard line data of the server 4; (2) display processing of the measurement item selection screen of the display control unit 333; and (3) the data transmission and reception unit 331 sends the standard line data corresponding to the measurement item selected by the user to Transfer processing by the measuring device 2.

On the other hand, in a case where the determination of the suitability of the two test drugs is consistent, the data processing unit 252 may also transmit the message to the portable information terminal 3. When the determination result is obtained, the data processing unit 332 of the portable information terminal 3 may perform the above-mentioned (1) to (3) processing for allowing the user to select a measurement item.

<Main effect>

In this embodiment, in the measuring device 2, the test suitability determination data is performed on the basis of the test suitability determination data. Therefore, when measuring the concentration of a substance, it is possible to prevent misuse of a reagent for a measurement item that should not be used in the measurement. At the same time, by uniformly managing the test suitability determination data in the storage device, it is possible to reliably perform a measurement that reflects the update of the test suitability determination data.

[Modification]
