In the present embodiment, the power failure monitoring circuit 16 of the terminal device 20 performs power failure, recovery from power failure, and
It is possible to output three types of signals indicating an abnormality of the backup battery of the terminal device 20. The leakage monitoring circuit 12 can monitor the leakage from the power line and the leakage from the power line, and for each of the leakage currents, depending on the amount of current flowing through the ground line, indicating that the amount of current is within a predetermined range. And a signal indicating "leakage" indicating that the amount of current exceeds a predetermined range (that is, a total of four types of signals). Further, the temperature monitoring circuit 14 determines whether the temperature of the high-voltage transformer rises.
It is possible to output four types of signals indicating “temperature 1 abnormality”, “temperature 2 abnormality”, “temperature 3 abnormality”, and “temperature 4 abnormality”. Accordingly, the headquarters monitoring computer 30 determines the plurality of types of abnormalities (power failure, warning of leakage, leakage, temperature 1).
(Up to 4 ascending), data indicating which situation should be notified by the terminal device can be registered.

Further, the headquarters monitoring computer 30 sets a pager number to be called when the terminal device 20 detects an abnormality, and stores the pager number in the database 38 in association with the ID number (step 303). ). The headquarters computer 30 can set a plurality of pager numbers.

Next, the headquarters monitoring computer 30 sets various necessary data on the monitoring side and stores them in a predetermined area of the database 38 (step 30).

This information includes, for example, data indicating whether it is necessary to call the pager when an error occurs on the headquarters monitoring computer 30 side, data indicating the pager number to be called, a warning sound or a warning screen when an error occurs, etc. And the data indicating the monthly inspection date of the electrical equipment in which the terminal device 20 is installed.

As shown in FIG. 3B, necessary information is also input to the terminal device 20 using an input device (not shown) such as a keyboard provided in the terminal device 20. It is stored in a built-in memory (not shown) (steps 311 to 313). Steps 311 to 313
Corresponds to the information set in steps 301 to 303 in the headquarters monitoring computer.

The input and registration in the above-mentioned steps 311 to 313 are performed, for example, at the installation location of the head office computer before the terminal device 20 is installed in the electric equipment. The housed housing is locked so that externally set conditions cannot be changed. As a result, it is possible to prevent mistakes, accidents, or malicious changes in the setting conditions by an external person, and to maintain the reliability of the apparatus.

Next, the processing in the terminal device 20 and the processing in the headquarters monitoring computer 30 responding thereto will be described. As shown in FIG. 4, the control / communication circuit 18 of the terminal device 20 determines whether a signal has been output from each of the power failure monitoring circuit 16, the leakage monitoring circuit 12, and the temperature monitoring circuit 14 (Step 401). If the determination is yes in this step, the type of the received signal is determined (step 402), and data necessary for transmission is created (step 403). More specifically, referring to the calling conditions registered in step 313 of FIG. 3, in response to the accepted signal, it is determined whether or not pager calling and notification to the headquarters monitoring computer 30 are necessary. If necessary, create data to be sent.

FIG. 5A is a diagram showing an example of a data format transmitted to the pager and the headquarters monitoring computer 30. As shown in FIG. 5A, the data includes an ID number and a data body in which each digit indicates the content of the abnormality. In this embodiment, the data body includes, in order from the beginning, a light leakage warning, a light leakage warning, a power leakage warning, a power leakage warning, a transformer temperature 1 abnormality, a transformer temperature 2 abnormality, a transformer temperature 3 abnormality, a transformer temperature 4 abnormality, This indicates a terminal battery abnormality or terminal power failure.
More specifically, in the present embodiment, if the digit is 0, it indicates that no abnormality has occurred. On the other hand, the same number as the digit (1 at the beginning, 1 on the right In case 2), it indicates that a corresponding abnormality has occurred. Note that the last digit (terminal power outage)
An abnormality is indicated by a predetermined alphabet (for example, “T”).

Next, from the built-in memory (not shown), FIG.
One or more pager numbers registered in step 314 are read out, and the created data is transmitted to the corresponding pager (step 404). This may use a public wireless line. Similarly, the control / communication circuit 1
8 transmits the obtained data to the headquarters monitoring computer 30 via the public line PX (step 405).
As a result, as shown in FIG. 6, when a predetermined abnormality occurs, the data generated in step 403 is transmitted from the terminal device 20 to the predetermined pagers 50-1 to 50-n set. , Numbers and characters are displayed on the display of the pager 50. This allows the chief engineer who owns the pager to know the occurrence of an abnormality and its recovery.

FIG. 5B is a diagram showing an example of a character string displayed on the display of the pager 50 when data is received from a terminal device to which an ID number 100 is assigned. For example, "100-0000000000T"
Is displayed, the chief engineer can know that a power outage has occurred in the electrical equipment connected to the terminal device. In this case, the called chief technician needs to urgently go to the site to check the electrical equipment. For example, after that, the character string “100-00000000” is displayed on the display of the pager. In this case, it is possible to understand that the power failure has been restored, and that the urgency has been released.

The called chief engineer can also know information other than the power failure from the display on the display of the pager 50. For example, in the example of FIG.
First, the "power line leakage warning" and the "transformer temperature 1 abnormality" are notified, and thereafter, the notification that the transformer temperature has returned (the fifth digit has returned from "5" to "0"). And the leakage of the power line was restored (the fourth digit is "4").
Has returned to “0” from the above). As described above, in the present embodiment, it is possible to notify the chief engineer of the type of the abnormality and the occurrence and recovery of the abnormality.
Therefore, the chief technician can flexibly take active positions based on the information.

Next, the headquarters monitoring computer 3 to which the data has been transmitted from the terminal device 20 in step 405 of FIG.
An explanation will be added for the processing of 0. FIG. 7 is a flowchart showing a process executed in response to data transmission.

The data processing unit 34 confirms the ID number included in the data and specifies the terminal device that transmitted the data (step 702). Further, the data processing unit 34
The ID number is transmitted to the database search unit 40. The database search unit 40 searches the database 38, and among the data related to the ID number, data indicating the customer (customer name data, customer address data, equipment capacity data, contact information, etc.). (Destination number data) and transmits it to the data processing unit 34. The data processing unit 34 generates image data based on the transmitted data, and outputs this to the display device (step 703). Thereby, on the screen of the display device,
It is possible to display a window including the name of the customer and its contact information.

Next, the data processing section 34 generates and outputs warning information according to the set conditions based on the contents of the abnormality indicated by the data (for example, a power failure, a leakage warning, etc.) (step 704). More specifically, appropriate warning voice data and warning image data are generated based on data indicating the type of warning sound or warning screen at the time of occurrence of an abnormality corresponding to the ID number (see step 306 in FIG. 3). These are output to an acoustic circuit (not shown) and a display device (not shown), respectively. The data processing unit 34 further includes:
According to the conditions set in step 306, if necessary, the necessary data is output to the second communication circuit 42 to call the pager of the registered number (step 705). Thereby, the second communication circuit 42
Sends a signal to a predetermined pager. Based on the signal transmitted from the second communication circuit 42, the called pager display screen is displayed as shown in FIG.
An image as shown in (c) may be displayed, or another type of image (for example, a warning display using characters) may be displayed.

Next, the data processing section 34 transmits data indicating the date and time of occurrence of the abnormality and the content of the abnormality to the database control section 36 together with the ID number.
Responds to this and stores the received data in a predetermined area specified by the ID number in the database 38 (step 706). Since the data stored in step 706 is stored for each ID number, it forms part of the abnormal data history.

As described above, according to the present embodiment,
From the terminal device 20, transmitting a signal indicating the ID number of the terminal device, occurrence and type of abnormality, and recovery from the abnormality to a pager carried by a predetermined chief engineer,
An image matching the transmitted signal is displayed on the screen of the pager, so that the chief engineer can respond flexibly according to the situation. In addition, when an abnormality occurs, it is possible to set for each terminal device whether to call the pager of the chief engineer, so that it is possible to provide a fine-grained maintenance service for each customer or facility. Become. Further, according to the present embodiment, the headquarters monitoring computer 30 also

For example, this processing is executed one week before the inspection date. In addition, the abnormality history totaling process creates a history indicating what kind of abnormality has occurred in each customer, for example, once a month.

The data processing unit 34 refers to a built-in timer (not shown) and, if the date is a predetermined date before the monthly inspection date by the engineer (for example, one week ago), The process shown in FIG. 8A is started. First, the data processing unit 3
4 requests the database search unit 40 to search for the ID number of the terminal device arranged in the facility to be inspected on the monthly inspection day. In response, the database search unit 40 searches the database to find a required ID number (step 801).

Next, the database search unit 40 reads out the data related to the customer from the data related to the ID number, and transmits the read data to the data processing unit 34 (step 802). This data includes customer name data, customer address data, equipment capacity data, contact number data, and the like. Based on the transmitted data, the data processing unit 34 converts data corresponding to a list (monthly inspection book) in which names, addresses, equipment capacities, telephone numbers, and the like of customers to be visited on the monthly inspection day are described. And outputs it to a printer (not shown) (step 80).
3). The data processing unit 34 may create a list according to the ID number (for example, in ascending order or descending order). For example, according to the customer address, a customer whose address is adjacent is arranged adjacently in the list. It is preferable to create a list as described below. The list (monthly inspection book) thus obtained may be sent separately to the chief engineer, or the corresponding data may be sent to the chief engineer via the communication circuit 32 and the public line PX. It may be transmitted to the computer to be used. As a result, the chief engineer can easily know which customer needs to be visited on the monthly inspection day, and the labor of the chief engineer can be reduced.

The data processing section 34 refers to a built-in timer (not shown) to execute the processing shown in FIG. 8B when a predetermined day (for example, the end of the month) occurs once a month. Start. First, the data processing unit 34 requests the database search unit 40 to search for an abnormal data history related to a predetermined ID number. In response to this, the database search unit 40 searches the database 38 for abnormal data histories related to the ID number, reads these data histories from the database 38, and transmits them to the data processing unit 34 (Step 812). ). The abnormal data history is stored in the database 38 in association with the ID number at step 706 in FIG. 7 every time an abnormality occurs or the abnormality is recovered.

Next, the data processing section 34 creates data corresponding to the history list associated with the ID number based on the transmitted data, and outputs this to the communication circuit 32 and a printer (not shown). (Step 813).
FIG. 9 is a diagram illustrating an example of the history list. As shown in FIG. 9, for each ID number (for each customer when only one terminal device is installed for each customer), the date and time at which the abnormality occurred, its contents, the date and time of its recovery, etc. in one month Is described. The communication circuit 32 converts the fax data into fax data, and transmits the fax data to the customer's fax via the public line PX (step 814). Therefore, according to the present embodiment, it is possible to present an abnormality that has occurred during a certain period to the customer in an easy-to-understand form, and thereby it is possible for the customer to grasp the problem in equipment security. Become. That is, based on the information transmitted by facsimile, it becomes possible for the business establishment to take measures to prevent accidents in advance. The data processing unit 34 repeats the processing of steps 811 to 814 for all customers (see steps 815 and 816), and thereafter ends the processing.
