In addition, by notifying other communication devices of the occurrence of an abnormality, the operator can be notified quickly and can respond very quickly. [Embodiment] An embodiment of the present invention will be described with reference to the drawings. In addition, examples of equipment used in the water and sewage systems are shown. (First Embodiment) As shown in FIG. 1, the data management collection system 1 of the first embodiment includes a data management device 2 including a display portion 24 such as a display, and a plurality of data transmission devices 3a, 3 b. In addition to the data management device 2 in the central monitoring room side, it also has a list machine for printing measurement data, etc. 4. A communication device (hereinafter, referred to as a modem 5) for connecting to external lines. 2 is an example of a flow screen displayed on the display of the display unit 24 in the data management device 2. As shown in Fig. 2, the real-time data of the measurement data collected by the data transmission device 3a near the current connection, and the data transmission device at the remote end that is currently not connected, (5) 1246007 the previous collection connection The batch data of the measurement data of 3b can be managed by the same plane. This is its characteristic. The data transmission device 3a receives measurement data measured by a measurement device (not shown), and superimposes the measurement data on the real-time management device 2 (called "real-time processing"). The data transmission device 3 b stores the measurement data measured by a measurement device not shown in a specific period in the measurement data recording unit 3 2. In response to the transmission request of the data management device 2, the measurement data is stored every specific period. Send a message to Data Management Device 2 ("Batch Processing"). The data transmission devices 3 a and 3 b send measurement data to the data management device 2 through one of the real-time processing and the batch processing, or both. Moreover, as shown in FIG. 2, real-time data and batch data are displayed on the display section 24 at the same time. With real-time data and batch data being processed and displayed at the same time, the data corresponding to the processing status of the chromium data transmission device can be managed as a whole. In order to make it possible to recognize that the data displayed on this display is real-time data or batch data, in the case of displaying batch data, it is set to add a net bottom display, and when real-time data is displayed, set to remove the net bottom Of display. For example, as shown in FIG. 3, the water depth of the distribution tank is displayed on the water depth display section 40a to display 9.99 m (meters). Since the water depth display section 40a is provided with a net bottom display, this display is batch data. In addition, the time display unit 40b displays the time when the data management device 2 performs batch processing on the measurement data of the distribution tank 40. In Fig. 3, the measurement data of the distribution tank 40 was processed at 12: 00: 00 on August 26, 2004 in batches. On the other hand, as shown in Fig. 4, the water depth of the distribution tank 41 is displayed on the water depth display section 41a, which is 7.89m. The water depth display 4 1 a is the display without the bottom of the net. Therefore, this display is displayed as real-time data. In addition, the time display unit 4 1 b displays the time when the data management device 对 device 2 performs real-time processing on the measurement data of the distribution pool 40. The current time is displayed. In Fig. 4, the measurement data of the distribution pool 41 at the time of 12:34:56 on August 26, 2004 was processed immediately. Here, as long as it is a difference that can be displayed, the method of distinguishing the display is not limited to adding a net bottom, for example, it may be displayed by changing the color. In addition, when displaying batch data, in order to let the operator know the time of the previous connection, the time of the previous connection end can also be displayed. As shown in FIG. 2, the line status display section 42 that displays the status of the line displays the time when the data management device 2 constructs a communication line via the general public line 6 or the dedicated line 8 and the data transmission device 3b. In the case of real-time processing, while "calling" is displayed, the time for constructing a communication line is displayed on the line status display section 42. The monitoring station display section 43 displays a data transmission device that constructs a communication line. In addition, "the measuring device (for on-site monitoring) near the central monitoring room is equipped with a data transmission device 3a, and is connected by a dedicated line such as RS-2 3 2 C" and often sends a message to the data management device 2 at a specific timing. Measurement data. In addition, the remotely-measured device (for off-site monitoring) is equipped with a data transmission device 3 b, and a general public line 6 or a dedicated line 8 (whether wired or wireless, or Optical fiber) 'periodically sends measurement data to the data management device 2 at a specific timing. In addition, the data management collection system 1 is prepared with FAX1 1 (fax) as an emergency contact point when an abnormality occurs, and for remote monitoring (7) 1246007 Computer 1 2.

The φ line monitoring unit 21 monitors and transmits the various data of the data transmission device 3 through the modem 5, and has the function of detecting the non-response state. The "non-response state" refers to a situation where an operator is connected to a communication line for more than a certain period of time. In addition, the data management section 22 has a specific timing to instruct the data machine 5 to build a communication line with the specific data transmission device 3, and to request the transmission of measurement data to the connected data transmission device 3, it will be transmitted through the data machine 5 The received measurement data is recorded in the database 2 3, and when the data transmission device 3 receives and displays the abnormal data, the notification of F Αχ n, the computer for remote monitoring 丨 2, mobile phone / PHS, etc. The function of the abnormal purpose. In addition, 'identify the machine information of the data transmission device 3 at the transmitting end, the time when the measurement data was received or the time when the test abnormality occurred, and the flag showing the reception status (upright or abnormal) 记录 is recorded in the data in relation to the measurement data Library 2 J. For example, 'as shown in 帛 5, when data management ㈤2 2 receives an abnormal signal generated when an abnormality occurs in the machine under test, the date, notification terminal, notification content, and notification are recorded in the database 2j. Type, result -10- (8) 1246007, report failure reason, etc. In addition, the 'data transmission device 3 is provided with a plurality of types of interfaces that can be connected to a plurality of types of communication lines, and includes: a communication section 31, a measurement data recording section 3 2, and a machine monitoring section 3 3. The memory device or auxiliary memory device memorizes the address data 3 4. Interfaces can be connected to wireless (packet communication), digital public lines (ISDN (Integrated Services Digital Network), etc.), analog lines (ADSL (Asymmetric Digital Subscriber Line), etc.), CATV (Cable TV), VPN (Virtual (Dedicated network) interface 0 The communication section 31 is equipped with a modem 5 via a general public line 6 or a dedicated line 8 to build a communication line. The data transmission device 3 and the data management device 2 — when connected, send a message. The function of the measurement data and the function of constructing a communication line to connect the data transmission device 3 and the data management device 2 to send abnormal data when an abnormality occurs. The measurement data storage unit 32 has a function of recording measurement data such as temperature data, pressure data, flow data, and the like provided by various measurement devices provided by the machine to be measured (so-called recorder function). The measurement data storage unit 32 is equipped with an emergency power source such as a battery so that the measurement data can be retained even in the event of a power failure (in terms of capacity, it can be stored for several days). In addition, even if measurement data cannot be transmitted, the measurement data can be maintained for several months to prevent loss of measurement data. In addition, the measurement data storage section 32 may be constituted by a nonvolatile semiconductor memory, such as a flash memory. As shown in FIG. 6, the data transfer device 3 may include an auxiliary memory unit 35 and an auxiliary power source 3 6 -11-(9) 1246007. The auxiliary memory section 3 5 series memory stores the same measurement data as the measurement data stored in the measurement data storage section 3 2. That is to say, a backup memory device for measuring data stored in the 35-series measurement data storage unit 3 2 of the 100-million unit. The auxiliary power source 36 supplies power to the data transmission device 3 when the power is cut off. The auxiliary power supply 3 6 supplies power to the communication unit 3 1, the measurement data storage unit 3 2, the machine monitoring unit 3, and the auxiliary recording unit 35. Even in the event of a power failure, the data transmission device 3 can operate normally. The machine monitoring section 3 3 is equipped with the receiving and receiving water equipment, such as pumps, piping, valve switching devices, etc., when abnormalities occur in the measured equipment, abnormal signals from various measuring devices, or measurement data storage section 3 2 If there is memorized measurement data of abnormality, abnormal data is recorded to record the abnormal state, indicating the function of sending the abnormal data to the communication department 31. The address data 3 4 is the data that the address information of the management device 2 was recorded when the abnormality occurred. < < Collection of normal measurement data > Next, the collection processing of normal measurement data will be described with reference to the sequence diagram of FIG. 7. Generally, the measurement data collection processing by the remote data transmission device 3b is performed as a batch process. In addition, measurement data such as temperature data, pressure data, and flow data supplied from various measurement devices are stored in the measurement data register with the measurement time. First, the data management unit 2 2 of the data management device 2 — detection has been -12- (10) 1246007 The time when the data transmission device 3 b arrives to send measurement data (step S 0 1), instructs the data machine 5 to construct and transmit the data The communication line of the device 3 b is connected to the data transmission device 3 b (step S 0 2). After the communication line is established, the data management unit 22 of the data management device 2 requests the data transmission device 3 b to send measurement data (step S 0 3), and the communication unit 3 1 of the data transmission device 3 b receives the data from the data management device 2 For measurement data requirements, the measurement data storage section 32 obtains the recorded measurement data and sends the acquired data to the data management device 2 (step S04) ° The data management section 22 of the data management device 2—receiving measurement Data, together with the received measurement data, will be recorded in the data to identify the machine information of the data transmission device 3 b at the transmitting end, the time when the measurement data was received, and the flag indicating the reception status (normal or abnormal). Library 23 (step S05). After recording specific measurement data in the database 23, the data management section 22 instructs the modem 5 to cut off the communication line with the data transmission device 3b, and cut off the communication line with the data transmission device 3b (step S06). In addition, the data transmission device 3 a near the central monitoring room is often connected to the data management device 2. Therefore, when the measurement data is supplied by various measurement devices, the data transmission device 3 a sends measurement data to the data management device 2 every time. Detailed description is omitted. The data management device 2 also records the measurement data transmitted by the data transmission device 3a in the database 23. The data management device 2 displays the measurement data collected by the data transmission device 3a and the data transmission device 3b on the display unit 24 of the data management device 2 together with the device to be measured. For example, along with the pipeline -13- (11) 1246007 of the water pipe, each measurement of temperature, pressure, and flow rate is updated and displayed at a specific time interval together with the measurement time or reception time. < < Circuit disconnection when abnormal > > Next, the circuit disconnection processing when the communication line is abnormal will be described with reference to the sequence diagram of FIG. 8. In the normal processing of collecting measurement data, the line monitoring section 21 of the data management device 2 monitors the communication status between the data management device 2 and the data transmission device 3 b. If, for a certain period of time, the data transmission device 3 b does not respond, such as continuous connection of the communication line, depending on the situation, it will also cause unnecessary consumption of the communication frequency band. In addition, it will also cause unnecessary communication costs and increase operating costs. Therefore, when a communication abnormality occurs, the communication line between the data management device 2 and the data transmission device 3 b is cut off and the communication line is opened. For example, if the operator leaves the seat and the line monitoring unit 21 judges that the communication line is connected more often than the preset time, the line monitoring unit 21 displays the selection information of whether the communication line is cut off or not on the line monitoring. Department 2 1. In the case where the disconnection of the communication line is selected, or in a case where it is not selected for a certain period of time, the line monitoring section 21 disconnects the communication line. First, when the data management unit 2 2 of the data management device 2 detects the time when the measurement data arrives at the data transmission device 3 b (step S 1 1), it instructs the modem 5 to construct a communication line with the data transmission device 3 b. The communication line for the data transmission device 3 b is connected (step S 1 2). After the communication line is established, the data management section of the data management device 2 -14-(12) 1246007 2 2 sends a request for measurement data to the data transmission device 3 b (step S 1 3). If the communication unit 31 of the data transmission device 3 b is normal, as soon as the data management device 2 receives the measurement data request, the measurement data recording unit 32 will obtain the recorded measurement data and send the acquired data to The information is sent to the data management device 2 (step S 1 4), and when there is some abnormal situation, it becomes no response. When the line monitoring unit 21 of the data management device 2 detects a non-response (step S 1 5), it is determined whether a specific time has elapsed without the response (step S 1 6). When a certain time elapses without a response, the line monitoring section 21 notifies the data management section 22 of the occurrence of a communication abnormality, and instructs the communication line to be disconnected. Data management section 22—If instructed to cut off the communication line, instruct the modem 5 to cut off the communication line with the data transmission device 3b, and cut off the communication line to the data transmission device 3b (step S17). In addition, the data management department 22 records the time when the abnormality occurred and the flag indicating the occurrence of the abnormality at the database 23. Next, the data management unit 22 of the data management device 2 displays a message such as a message indicating the occurrence of a communication abnormality on the display of the display unit 24 (step S 1 8), and notifies the operator. For example, usually on the screen displaying the measurement data from the pipelines of the upper and lower water pipes and the measurement data of each data transmission device 3 a and 3 b, in the case of a non-response state, a message with the intention of the occurrence of a communication abnormality, or a display on the network bottom, The warning signs are displayed at the same time as the moment when they become unresponsive. In this way, in the case where there is no response on the side of the data transmission device 3, by cutting off the communication line from the data management device 2, it is possible to prevent unnecessary communication costs -15- (13) 1246007. < < Notification when an abnormality occurs > > Next, the notification processing when an abnormality occurs will be described with reference to the sequence diagram of FIG. When an abnormality occurs in the equipment to be measured, such as pumps, piping, valve switching devices, etc., the data transmission device 3 b is connected to a device registered in the notification side in advance to report an abnormality. Based on the stopping or failure of the pump, the flow rate is reduced, the water pressure in the piping exceeds the critical threshold, and the failure of the valve to adjust the flow rate, based on the measurement data of the flow sensor or pressure sensor, the machine The monitoring unit 33 senses an abnormality of the device to be measured. Or the water quality (residual chlorine concentration, turbidity), water temperature, water pressure, water level, flow rate, chromaticity and other processes (critical) exceed the threshold, the data transmission device 3 is connected to a device registered in the notification terminal in advance to report an abnormality occur. That is, when the measurement data measured by the measuring device exceeds a certain critical threshold, the machine monitoring section 33 senses the abnormality of the equipment machine, the measurement threshold, and the system, and issues an abnormal signal. First, the machine monitoring section 33 of the data transmission device 3 b receives an abnormal signal from various measuring devices, or detects that the measurement data storage section 32 has stored abnormal measurement data (step S21), and records the abnormality. The abnormal data of the condition is instructed to the communication department 31 to send the abnormal data. The communication section 31 refers to the address data 3 4 according to the instructions from the machine monitoring section 33, and connects the data management device 2 and the data transmission device 3 b to the communication -16-(14) 1246007 line (step S 2 2). The data management device 2 sends abnormal data (step S 2 3). In the case where the data management device 2 does not receive abnormal data and the transmission is not completed (in the case of NO in step S24), or in the case that the communication line cannot be connected in step S2 2, the communication unit 31 is waiting for a specific time After that, connect the communication line again. For example, the communication unit 31 reconnects the communication line at a preset number of times. The communication department 31 will display information on whether the abnormal data has been sent and the reason why the abnormal data was not sent (during the call on the receiving side, no one on the receiving side, etc.) as data to be stored. The communication department 31 sends these data to the data management device 2 to be stored in the database 23. The data management unit 22 of the data management device 2—when receiving abnormal data, a message (warning sound, sound, document, etc.) indicating the occurrence of the abnormality is made, and the warning data of the occurrence of the abnormality and the abnormality are displayed on the display unit 24 . In addition, the data management unit 22 transmits warning data to communication equipment such as FAX1 1, computer for remote monitoring and monitoring 1, 2 mobile phones / PHS 1 3 carried by the operator via the network 7. The communication section 3 1 of the data transmission device 3 may directly transmit abnormal data or warning data to the communication device through the general public line 6, the network 7, and the dedicated line 8. In this case, the machine monitoring section 33 generates abnormal data and warning data, and the communication section 31 continues to connect the communication line until the transmission of the abnormal data or warning data is completed. In addition, the address of each communication device is registered in the address data 34, and according to this address, abnormal data or warning data is sent to each communication device. The data management unit 22 may output the abnormality status registered in the abnormal data to the list machine 4. -17- (15) 1246007 After the communication line is connected and the abnormal data transmission is completed, the communication department 31 disconnects the communication line (step S 2 5). In this way, “by reporting an abnormality, the operator can be notified quickly.” In an emergency, it can respond quickly. The data management unit 2 of the data management device 2-When receiving abnormal data ′, the warning data indicating the occurrence of an abnormality and the status of the abnormality are displayed on the display unit 24. For example, as shown in Fig. 10, a tag number, a tag name, a warning message, a level, a time, and the like are displayed. The warning of the standard iron number D 1 0 0 0 is a failure that is not as good as the 2 in the figure 2. The abnormality level of chestnut 44 is an unconfirmed level. In addition, the warning of the flag number D 1 0 0 1 indicates that the upper limit of the distribution pool 4 0 shown in FIG. 2 is abnormal. In addition, the abnormality level of the distribution tank 40 is a confirmed level. You can also change the display color and make the display flicker in response to the abnormal level. In the notification processing when an abnormality occurs, the data management department 22 records the abnormal data or warning data to the communication device in the database 2 3. For example, 'as shown in Fig. 5, N. 1 1 1 sends warning data to the fax machine on August 25, 2004 19: 30: 4: 2 seconds, but the transmission failed 0 (Second Embodiment) As shown in FIG. 11, the data management and collection system of the second embodiment is implemented at the point that the data transmission device 3 b further includes an interface 37 connected to the communication unit 31 and is the first implementation. The form is different. In addition, the communication department 31 constructs communication lines through general public lines 6 or dedicated lines 8 'and other data transmission devices 3 c -18- (16) 1246007, and obtains the measurements of 100 million stored in other data transmission devices 3 c. The data is different from the first embodiment in that the acquired measurement data is stored in the measurement data storage section 32. The communication unit 31 can also directly store the measurement data obtained by the data transmission device 3 c on the computer 14 through the interface 37. The computer 1 4 is connected to the data transmission device 3 b through the interface 3 7. The computer 14 reads the measurement data memorized in the measurement data and the measurement data stored in the measurement data storage unit 32 through the communication unit 31. Or the computer 14 can directly read the measurement data from the communication unit 31. Such measurement data is not only the measurement data of the data transmission device 3 b connected to the computer 14, but also the measurement data of other data transmission devices 3 c. < < Collection of normal measurement data > Next, a description will be given of a collection process of normal measurement data with reference to the sequence diagram of FIG. 12. Generally, the measurement data collection processing by the remotely located data transmission device 3c is performed as a batch process. In addition, measurement data such as temperature data, pressure data, and flow data supplied from various measurement devices are stored together with the measurement time in a measurement data memory section (not shown) of the data transmission device 3c. First, the computer 14 sends a command to collect the measurement data of the data transmission device 3 c to the data transmission device 3 b. The communication unit 31 detects the measurement data collection command (step S 3 1), refers to the address data 3 4, and connects to the communication line of the data transmission device 3 c (step S 3 2). After the communication line is established, the communication department 3 of the data transmission device 3 b is required to send measurement data to the -19- (17) 1246007 (3). The communication department of the data transmission device 3 c When receiving the measurement data request from the data transmission device 3 b, the measurement data storage section obtains the recorded measurement data, and sends the acquired data to the data transmission device 3 b (step S 3 4). Communication section 3 1 of the data transmission device 3 b — the reception measurement data, together with the reception measurement data, will identify the machine information of the data transmission device 3 c at the transmitting end, the time of the reception measurement data, and display the reception data. The flag 値 of the signal status (normal or abnormal) is recorded in the measurement data storage section 3 2 (step S 3 5). The communication department 31 can also identify the machine information of the data transmission device 3 c on the communication side, the time of receiving the measurement data, and the flag indicating the receiving status (normal or abnormal) together with the received measurement data. Recorded in the computer 1 4 > After recording specific measurement data in the measurement data storage section 32, the communication section 31 cuts off the communication line with the data transmission device 3c (step S36). For the requirements of the measurement data, the data The transmission device 3 c has no response. In step S 35, the communication unit 3 1 of the data transmission device 3 b cannot receive the measurement data within a specific time, as in the first embodiment shown in FIG. 8. The procedure is the same, the communication section 31 can also cut off the communication line with the data transmission device 3c. In addition, in the case where the data transmission device 3 b and the data transmission device 3 c are often connected by a dedicated line 8, the step S36 of disconnecting the communication line may be omitted. 〇 The measurement data and warning history collected by the data transmission device 3 c will be -20- (18) 1246007, trend curve, and program information are displayed together on the display section of the computer 14. In the address data 34, the address information of the data transmission device 3c is recorded. The address information registered in the address data 34 can be updated via the computer 14 or the data management section 22 shown in FIG. 1. According to the second embodiment, not only the data management device 2 but also the data transmission device 3 b can collect the measurement data of each data transmission device 3 c. In addition, even in the case of failure of the data management device 2, the data transmission device 3b can directly collect measurement data by the data transmission device 3c. (Other Embodiments) The data management and collection system of the other embodiments is the data management and collection system of the first embodiment and the second embodiment, and the data management unit 22 sets and changes the data transmission device 3 according to online or offline. 3 Sampling interval for memorizing measurement data. As shown in FIG. 13, the data management section 22 manages the sampling intervals of the data transmission devices 3 a, 3 b, and 3 c of the monitoring station. Normally, in the first sampling interval, the data transmission device 3 receives measurement data measured by the measurement device. The data transfer device 3a shown in Figs. 1 and 6 performs sampling at 1 minute intervals. The data transfer device 3b shown in Figs. 1, 6, and 11 performs sampling at 5-minute intervals. The data transfer device 3 c shown in Fig. 11 performs sampling at 10 minute intervals. In the case where the data transmission device 3 performs sampling at a second sampling interval shorter than the first sampling interval, the data management unit 22 selects the second sampling interval and causes the data transmission device 3 to perform sampling. When the second sampling interval is selected, the data transfer device 3a performs sampling at 30 second intervals. Data transfer device 3 b -21-(19) 1246007 Sampling is performed at 1 minute intervals. The data transfer device 3 c performs sampling in real time. The second sampling interval is changed by the data management unit 22. Even when the second sampling interval is selected, the data transmission device 3 performs sampling at the first sampling interval. The database 2 3 shown in Fig. 14 stores measurement data sampled at the first sampling interval. In addition, measurement data sampled at the second sampling interval are stored in the database 25. If the stored measurement data exceeds the data storage capacity of the database 25, the measurement data received first will be eliminated in order. According to other embodiments, the sampling interval of each data transmission device 3 can be managed by the central monitoring room. In addition, even in the case where the sampling interval is desirably shortened, the sampling interval of each data transfer device 3 can be quickly changed from the central monitoring room.
