〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a functional block diagram. In this figure, (1) is a monitoring device that has each of the functions (2) to (7), and (8) is a monitoring device that has each of the functions (2) to (7).
) is a receiving device that receives abnormal data sent from the monitoring device (1), (2) is a monitoring means that captures the status of each equipment and monitors abnormalities, and (3) is a device that opens, closes and closes telephone lines. While this telephone is in use, line control means detects incoming calls and controls dialing, (4) is a transmitting means that transmits abnormal data to the receiving device (8), and (5) is an abnormality transmitted to the receiving means (8). History means for logging data; (8) is a clock means for counting every minute up to 24 hours; (7) is daily data when the time counted by clock means (6) reaches 24:00; This is a daily change history means that records the changes.

Figure 2 shows its hardware configuration, where (9) is the network control unit, (10) is the microprocessor, (11) is the P and B signal transmitting unit, and (12) is the destination telephone number and monitoring. Memory, which sets the number of the building that the device is monitoring.
(13) is a buffer memory that stores historical data, (1
4) is a history display device. Here, the microprocessor (1o) receives the detection that the telephone is in use and the detection of an incoming call from the network control unit (9), and sends line closing/opening commands and dialing commands in order to control the telephone line. In addition, in order to transmit abnormal data to the receiving device (8), when an incoming call response from the receiving device (8) is detected, data is transmitted from the P and B signal transmitting section (11). being done.

Next, the operation will be explained with reference to the flowchart shown in FIG. In S (3-1) to S (3-3), the status of each piece of equipment is captured, and for equipment that has experienced an abnormal change in status,
Create the data to be sent to the receiving device by adding the building number. In S (3-4) to S (3-7), in order to make a call, first turn on the dS relay and monitor whether the line is idle for a certain period of time (here, for example, 3.5 seconds).

This phone is in use at S (3-5) (T relay is ON)
If so, return to S (3-4).

If an incoming call is detected in S (3-6) (R relay is turned on), the process returns to S (3-4). After confirming that the line is free for 3.5 seconds, go to S (3-8).

However, S (3-8) closes the line (S relay O
N, ds relay OFF) L/, S (3-9) retrieves the destination phone number from memory (12) and dP
Perform dialing by ON/OFF control of the relay, turn the dS relay OII, and change from S (3-10) to S (
3-12), it is monitored whether the receiving device (8) has responded. Here, it is assumed that monitoring is performed for 30 seconds. And S
If there is a response detected (polarity reversal of E relay) in (3-11), go to S (3-13), otherwise go to S (3-1
The monitoring time is checked in step 2), and if 30 seconds have not elapsed, the process returns to S (3-11) and response monitoring is repeated. After 30 seconds, go to 5 (3-19).

Then, in S (3-13), the abnormal data for transmission created in S (3-3) is converted into P and B signals, and the P and B signal transmitting section (11) transmits the signals. In S (3-14) to S (3-18), the receiving device (8) monitors the reply of the response signal ENQ indicating whether or not it has received data (here, it takes 2 seconds), and sends a signal when it receives this εNQ signal. It is determined as a success and the success flag is set to ONL/, and if it is not received even after 2 seconds, it is determined to be a failure and the failure flag is set to ONS (3-19).

S (3-19) opens the line (S relay OFF,
d S relay 0FF) Go to S (3-20). In S (3-20), the abnormal data transmitted in step 5 (3-13) is stored in the history data buffer (13) according to the abnormal data history format shown in FIG. 5(a) and sent to S.
Return to (3-1).

Next, FIG. 4 shows the clock function. The time is counted minute by minute, and the time progresses up to 24 hours. S
When 24 hours have passed in (4-4), the daily data is stored in the history data buffer (13) according to the format shown in Figure 5 (b) in S (4-5), and the return time is returned to S (4-1). clear.

Figures 5 (a) and (b) are the formats of historical data, time (5-1) sets the time to operate according to the flow in Figure 4, and destination (5-2) indicates the destination of the call. The receiving device number (5-3) when there are multiple locations is S (3-1
4) to S (3-18) indicate the result of the ENQ signal reply, for example, “FF” for success, Oo for failure.
Set °′. The transmitted abnormality code is encoded and set in (5-4). Here, (5-1) is 2 bytes,
(5-2) and (5-3) are expressed in 1 byte, and (5
-4) is one byte per one abnormal code, and up to four abnormal codes can be set. (5-5) sets 2 bytes "00" and sets "FF" in the next 6 bytes, as data indicating that 24 hours have passed.

Note that in the above embodiment, the history data buffer (13
) The format of the data set in 8 bytes per data is shown, but it may be increased so that even more abnormal codes can be set. Also, in the format of the daily change history, "oo" and "FF" are used, but as long as it can be distinguished from the history of abnormal data, any of the numbers 0 to 9 and the letters A to F can be used. good.

24 times in the history of abnormal data instead of the history of daily data
One byte of data that is counted up every time may be added. In other words, 24 hours have not passed until this number changes.

(Effects of the Invention) As described above, according to the present invention, the clock means counts the time up to 24:00, and when the clock reaches 24:00, the daily data is recorded in the history data buffer. Even if the monitoring device does not have a function or does not have the function of periodically transmitting to a receiving device, looking at the historical data,
It is possible to check on the monitoring device side when an abnormality was sent and how many abnormalities occurred in a day.
