BACKGROUND OF THE INVENTION
The invention of the present application includes a test apparatus that analyzes a specific component in a specimen, and an information processing apparatus that manages the test by the test apparatus and processes and manages the test result. The test apparatus and the information processing apparatus include: relates to analyte test system is capable of transmitting and receiving data via a communication line with each other.
[0002]
[Prior art]
Recently, data communication using a computer such as a personal computer have been actively carried out. In particular, so-called personal computer communication is used not only for communication between personal computer owners but also in various fields. For example, in an inspection center or the like, data such as inspection results by the inspection device is transmitted to a host computer located away from the inspection device via a communication line, and the inspection results by the inspection device are centrally managed in one place. It is also used.
[0003]
In an examination center or the like, an extremely large number of specimens of the same kind must be examined, and therefore a plurality of examination apparatuses of the same type are arranged. In such a case, it is necessary to unify setting conditions among the plurality of inspection apparatuses, for example, measurement conditions such as measurement sensitivity.
[0004]
[Problems to be solved by the invention]
However, in a facility where a plurality of the same inspection apparatuses are arranged as described above, when changing the setting conditions, for example, the measurement conditions such as the measurement sensitivity, the setting conditions of the plurality of inspection apparatuses are manually changed one by one. It was changed by input.
[0005]
However, changing the setting conditions of each inspection device by manual input one by one requires a great deal of labor and time. In addition, if a great deal of time is spent changing the setting conditions of each inspection apparatus, the properties of the prepared specimen change, and the specimen cannot be examined in a desired state. In addition, when changing the setting conditions of each testing device by manual input, there is a high probability that an input error will inevitably occur. If the sample is measured under the setting conditions input due to an input error, the value that should be measured originally a different value will be measured.
[0006]
The present invention has been conceived under the circumstances described above, and in a facility having a plurality of inspection devices of the same type, such as an inspection center, reliably without setting the setting conditions of the plurality of inspection devices. and as its object to provide a collectively analyte test system that can change the setting conditions to the same setting conditions.
[0007]
DISCLOSURE OF THE INVENTION
In order to solve the above problems, the present invention takes the following technical means.

And a re-transmission means for re-transmitting data of the subsequent setting conditions .
[0010]
According to such a specimen testing system, when the setting conditions are changed in a facility where a plurality of the same type of testing apparatuses are arranged, the setting conditions of the plurality of testing apparatuses are manually changed by manual input one by one. Without setting, it is possible to change the setting conditions of the inspection devices selected at once by operating an information processing device connected to the inspection device via a communication line. In other words, the setting conditions of the plurality of inspection apparatuses can be collectively changed by operating the information processing apparatus without requiring much labor such as manpower and time. Furthermore, the probability of causing an input error, which was an incidental to the change of setting conditions by conventional manual input, is extremely low.

[0028]
Next, the operation of the specimen test system configured as described above will be described. First, when the changed setting condition is input to the information processing apparatus 12 by the operator , the inspection apparatus 32 that should change the setting condition is selected from the information processing apparatus 12 side. Then it sends the data after the change in one inspection device 32 of the inspection apparatus 32 that is selected. The inspection device 32 that has received the data determines whether the checksum of the received data is normal, and notifies the information processing device 12 of the result. When the notification sent from the inspection device 32 is a notification that the inspection device 32 has not received normally, or the information processing device 12 has not received a notification from the inspection device 32 within a predetermined time. Then, the changed data is retransmitted to the inspection device 32. The inspection device 32 changes the existing data to the received data when the changed data is normally received. In addition, the operation which should change the setting conditions of the above inspection apparatuses 32 with respect to all the selected inspection apparatuses 32 is performed.
[0029]
Next, a procedure for changing the specimen test system configured as described above will be described with reference to the flowcharts shown in FIGS.
[0030]
FIG. 2 is a flowchart showing the procedure of the change process on the information processing apparatus 12 side. The procedure of the change process on the information processing apparatus 12 side will be described below. In addition, the information processing apparatus 12 and the inspection apparatus 32 in this embodiment are arrange | positioned in the same building or another building distant from each other, and data transmission / reception shall be performed mutually via a communication line.
[0031]
First, the processor 1 determines whether or not the changed setting condition is input to the information processing apparatus 12 by the operator (S1). When the processor 1 determines that the changed setting condition has been input (S1: YES), the operator subsequently selects the inspection device 32 whose setting condition is to be changed, and the processor 1 ends the selection by the operator. It is determined whether or not (S2). The selection of the inspection device 32 whose setting conditions are to be changed from the information processing device 12 side is performed by selecting an address number or an ID number assigned to each inspection device 32. Further, the end of the selection of the inspection apparatus 32 whose setting conditions are to be changed by the processor 1 is determined by whether or not the selection end command is input by the operator.
[0032]
In S2, if the processor 1 determines that the selection of the inspection device 32 whose setting condition is to be changed is not completed (S2: NO), the selection of the inspection device 32 whose setting condition is to be changed by the processor 1 is completed. The above determination is repeated until it is determined that it has been made. When the processor 1 determines that the selection of the inspection device 32 whose setting conditions are to be changed is completed (S2: YES), the operator gives an instruction to transmit the input changed setting conditions to the inspection device 32. It is judged by the processor 1 whether or not it has been inputted (S3).
[0033]
In S3, when the processor 1 determines that the instruction to transmit the inputted changed setting condition is not inputted by the operator (S3: NO), the inputted setting condition after the change is inspected by the inspection device. The above determination is repeated until it is determined that an instruction to be transmitted to 32 is input by the processor 1.
[0034]
In S3, when the processor 1 determines that an instruction to transmit the input changed setting condition to the inspection apparatus 32 is input by the operator (S3: YES), the information processing apparatus 12 changes the inspection apparatus 32 to the inspection apparatus 32. The changed setting condition data is transmitted (S4), and a timer is set (S5). Note that a countdown type timer is used as the timer in the present embodiment. Specifically, an integer variable N is set in accordance with the time when the timer should be set, and the value of the variable N is sequentially decreased by 1 in synchronization with a clock signal having a predetermined period, and the variable N becomes 0. The time is up.
[0035]
Next, it is determined whether or not a notification indicating that the changed setting condition data transmitted from the information processing apparatus 12 has been received from the inspection apparatus 32 has been sent (S6). When the processor 1 determines that the notification has not been sent from the inspection device 32 (S6: NO), the processor 1 monitors the timer and determines whether the time is up, that is, whether the variable N is 0 or not. Judgment is made (S9). Processor 1 is not a time-up, that is, if it is determined that the variable N is not 0 (S9: NO), or processor 1 determines that the notification is sent (S6: YES), or a time-up, That is, it waits until it is determined that the variable N is 0 (S9: YES).
[0036]
In S6, when the processor 1 determines that a notification that the changed data has been received has been sent from the inspection device 32 (S6: YES), the notification indicates that the inspection device 32 has made normal data normal. It is determined whether or not the notification is received (S7). Note that whether or not the inspection device 32 by the processor 1 has successfully received the changed setting condition data sent from the information processing device 12 is determined by the value of the flag sent from the inspection device 32 side. Is done. Specifically, when the inspection device 32 normally receives, the flag value is set to 0. When the inspection device 32 does not normally receive, the flag value is set to 1, and the inspection device 32 sends the information to the information processing device 12. The value of this flag is transmitted, and the processor 1 determines from this value whether or not the inspection device 32 has received normally.
[0037]
In S7, if the processor 1 determines that the notification is a notification that the inspection device 32 has not received normal data of the changed setting condition (S7: NO), or in S9, the processor 1 When the time is up, that is, when it is determined that the variable N is 0 (S9: YES), the processor 1 retransmits the changed setting condition data from the information processing device 12 to the inspection device 32 (S10). .
[0038]
In S7, when the processor 1 determines that the notification received by the information processing device 12 is a notification that the inspection device 32 has successfully received the changed data (S7: YES), or in S10, retransmission is performed. If it has been determined, it is determined whether or not the setting conditions have been changed for all the inspection apparatuses 32 whose setting conditions selected in S1 are to be changed (S8).
[0039]
In S8, when it is determined that the setting conditions are not changed for all the inspection apparatuses 32 that should change the selected setting conditions (S8: NO), the process returns to S4 and the setting conditions are changed. The changed data is transmitted to the other selected inspection apparatus 32 that has not been performed, and the operation is repeated in the same manner.
[0040]
When the processor 1 determines in S1 that the changed setting condition has not been input (S1: NO), or in S8, the setting is made for all the inspection devices 32 that should change the setting condition selected by the processor 1. If it is determined that the condition has been changed (S8: YES), this routine is terminated.
[0041]
Next, the procedure of change processing on the inspection apparatus 32 side will be described based on the flowchart shown in FIG.
[0042]
First, the CPU 21 determines whether or not there is a transmission request for the changed setting condition from the information processing apparatus 12 (S21). If the CPU 21 determines that there has been a request for transmission of the changed setting condition (S21: YES), it receives the changed setting condition data sent from the information processing device 12 (S22).
[0043]
Subsequently, the CPU 21 determines whether or not the reception of the changed setting condition data sent from the information processing apparatus 12 has ended (S23). When the CPU 21 determines that reception of the changed setting condition data sent from the information processing device 12 has not ended (S23: NO), until the CPU 21 determines that reception of the data has ended. The above determination is repeated.
[0044]
If the CPU 21 determines in S23 that the reception of the changed setting condition data sent from the information processing apparatus 12 has ended (S23: YES), it determines whether or not the checksum is normal. (S24).
[0045]
If the CPU 21 determines in S24 that the checksum is normal (S24: YES), it means that the normal data has been received normally, so that the CPU 21 has received the normal data after changing the setting conditions. Is notified to the information processing apparatus 12 (S25). Specifically, if the checksum is normal, the flag is set to 0, and this value is transmitted to the information processing apparatus 12 based on the control of the CPU 21. Subsequently, the CPU 21 executes the program stored in the ROM 22 to change the changed setting condition data received from the existing setting condition stored in the RAM 23 (S27).
[0046]
If the CPU 21 determines that the checksum is not normal in S24 (S24: NO) , it means that the normal data could not be received, so the CPU 21 did not receive the normal data after changing the setting conditions. The information processing apparatus 12 is notified of the fact, that is, the flag is set to 1, and the information processing apparatus 12 is notified (S26).
[0047]
When the CPU 21 changes the data to the changed setting condition data received from the existing setting condition stored in the RAM 23 (S27), the information processing apparatus indicates that the CPU 21 has not received normal data after the setting condition change. 12 is notified (S26), or when the CPU 21 determines in S21 that there is no transmission request for the changed setting condition from the information processing apparatus 12 (S1: NO), this routine is terminated.
[0048]
According to such a specimen testing system, when the setting conditions are changed in a facility where a plurality of the same type of testing apparatuses 32 are arranged, the setting conditions of the plurality of testing apparatuses 32 are manually input one by one. The setting conditions of the inspection device 32 selected by operating the information processing device 12 connected to the inspection device via a communication line can be changed in a lump without changing them. That is, it is possible to change the setting conditions of the plurality of inspection apparatuses 32 without requiring much labor such as manpower and time. Furthermore, the probability of causing an input error, which was an incidental to the change of setting conditions by conventional manual input, is extremely low.
[0049]
Furthermore, in the sample testing system according to the present embodiment, a notification as to whether or not the changed setting condition data has been normally received from the testing device 32 is sent to the information processing device 12. It can be determined whether or not the changed setting condition data transmitted from the information processing apparatus 12 by the operator has been normally received by the inspection apparatus 32. That is, as in the present embodiment, the operator on the information processing apparatus 12 side can respond by retransmitting the inspection apparatus 32 so that it is not set to an incorrect setting condition, and the setting condition of the inspection apparatus 32 is incorrect. Thus, it is possible to avoid the examination of the specimen in the state in which it is in the state of being.
[0050]
Of course, the scope of the present invention is not limited to the embodiment described above. For example, data transmission / reception between the information processing apparatus 12 and the inspection apparatus 32 may be performed using a LAN (local area network) as a communication line, or not limited thereto, but using a telephone line as a communication line. It may be.
[0051]
The selection of the inspection device 32 to which the changed setting condition is to be transmitted is a selective matter. In a facility where only a plurality of inspection devices 32 of the same type are arranged, the changed setting condition is transmitted. It is not necessary to select the inspection device 32 to be selected. In a facility where a plurality of types of inspection devices 32 are arranged, a specific type of inspection device 32 is selected from the plurality of types of inspection devices 32. You may comprise.
[0052]
Additional, when the information processing apparatus 12 has performed the data retransmission may constitute notification from the inspection apparatus 32 to the effect that has received the data to send to the information processing apparatus 12.
