Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an emergency notification device using a telephone line.

[Conventional technology]

FIG. 3 is a schematic circuit diagram showing a conventional emergency notification device disclosed in, for example, Japanese Patent Publication No. 56-46639. In FIG. 1, (1) is an emergency notification device, (2) is a telephone line, ( 3) is this telephone, (4) is a disconnector that separates emergency notification device (1) and this telephone (3), (5a), (5

The line network control circuit performs automatic dialing to the 91u reception center, αI is the central processing control circuit, aυ is the modulation/demodulation circuit that modulates and demodulates the notification data into a signal suitable for the telephone line (1), (1 is the equipment monitoring circuit) , (13 is the reception center telephone number storage circuit, (I4 is the building number storage circuit, Q!9

ae is a reset circuit that outputs an output when the power is turned on; (Ha) and (t7b) are switches that connect and disconnect the power supply (6) and the battery (8).

Next, we will discuss the operation. Swift f (17a), (
17b) is turned on, the power supply (6) and the battery (8) are connected to the power supply circuit (7), and power is supplied to all circuits (not shown), and the timer circuit is activated by the output from the reset circuit αe. AS and the central processing control circuit are initialized. When a failure occurs in any of the equipment (5a), (sb), or (sc), the central processing control circuit Ql sends a message to the telephone number storage circuit 0 to the line network control circuit (9) based on the input from the equipment monitoring circuit a. Automatic dialing of the stored phone number of the receiving center is performed (1) When the receiving device on the receiving center side responds (not shown), the modem circuit Ql)
The building management number and information on the faulty equipment stored in the building number storage circuit I are sent to the receiving device through the receiving device, and when the sending is finished, the line (1) is restored and the device enters a standby state. On the other hand, the timer circuit a9 initialized by the output of the reset circuit Q frame outputs an output every 24 hours, and the central processing unit aI
Using the same procedure as on Fi, the building management number and the facility operating status (that there are no broken facilities) are reported to the receiving device. As a result, the receiving center receives notifications when equipment malfunctions occur, and if no equipment malfunctions occur, it receives reports on the equipment operating status at regular intervals indicating that the equipment is operating normally. , When a failure actually occurs in the equipment, a failure occurs somewhere in the emergency notification device (1) and the equipment is monitored remotely to prevent the failure from being reported. This reporting operation is performed by Babuteli (8), for example, at 30
If the power outage is for a short period of time (about 9 minutes), it will be carried out no differently than normal.

[Problem that the invention seeks to solve]

Since conventional emergency notification devices are configured as described above, if the switches of emergency notification devices installed in different buildings are turned on at the same time, the notifications carried out at predetermined time intervals may overlap at the receiving center. Normally, it is unthinkable that emergency notification devices in different buildings would be turned on at exactly the same time unless this was done intentionally, but 2. For example, if a large-scale power outage occurs for a long time that exceeds the backup time, the power will be restored. At that time, all the emergency notification devices in the area are in the same state as if they had been turned on at exactly the same time, and after that, an extremely large number of calls were concentrated at the reception center at a given time, and it became impossible to receive all the calls. However, there was a problem in that the desired remote monitoring operation could not be performed.

This invention was made in order to solve the above-mentioned problems, and after a long-term large-scale power outage occurs and the power is restored, it is possible to prevent notifications carried out at predetermined time intervals from being concentrated at the receiving center. The purpose is to obtain an emergency notification device [
Means for Solving the Problems] An emergency notification device according to the present invention includes an initial value setting circuit that calculates an initial value based on a value set by an external operation, a memory that stores the initial value, and this memory. A counter is provided to add and count clock pulses to the value read from the counter, and when this count value reaches a predetermined value, the memory is set to zero and the alarm means is activated.

[Effect]

In the emergency notification device of the present invention, a different initial value is set for each building, and the alarm means is activated when a predetermined value is reached using this initial value as a starting point.〇 [Embodiment of the invention] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, the same symbols as in Figure 3 are IW! ' In Figure 1, which shows a portion, 0 seconds is when a predetermined arithmetic processing is performed on the content of the building management number, which differs for each individual building, stored in the building number storage circuit a4, and the reset operation time limit circuit Q! 19
This is an initial value setting circuit that sets the initial value of 1 to a value corresponding to the content of the building management number, which differs for each individual building.

Figure 2 I/i Building number storage circuit I, initial value setting circuit αS and time limit circuit Q shown in Figure 1! In the figure, e (s 4a) is the building number setting switch, (x
4b) is an output circuit that outputs the building number, (18
A) is an arithmetic circuit that performs predetermined arithmetic operations based on the building number, for example, (AX (building number) + B) and outputs the result from the output circuit (18b). (15a
) is a removable memory (
Hereinafter, it will be referred to as RAM. ) (1sb) is an oscillator that generates clock pulses, (15C) is a counter that adds and counts the clock pulses of the oscillation circuit (15b) to the value stored in AM (15a), and the added value becomes zero every time it reaches a value equivalent to 24 hours. outputs a significant signal and outputs a significant signal to the central processing control circuit (1
At the same time, RAM (15a) is cleared to make the stored value zero.

Explain the action to the arrow. Switch (17a), (1
7b) is introduced. Or switch (x7a), (
Hb) is turned on, but Bavteri (8) is completely discharged and when the power outage is restored, an output is generated from the reset circuit Q, and after the initial value setting circuit α8Fi output circuit (tab) is reset, the building is reset again. Predetermined arithmetic processing is performed on the building management numbers that are different for each individual building stored in the number storage circuit I. This processing result is output from the output circuit (18b) and stored in RAM (15a), and with this stored value as the initial value, the number of pulses from the oscillation circuit (xsb) is added by a counter (15C) and . This added value is 24
When the value corresponding to the time is reached, a significant signal is output and transmitted to the central processing control circuit 0 (I), and the ordinary person M
Set the value of (tsa) to zero. In other words, the notification operation is performed without waiting for 24 hours. From the next time onwards, the initial value when the counter (15C) counts clock pulses will be zero, and notifications will be made every 24 hours from the first notification after the power outage.

That is, an output is issued from the reset circuit 08, and after the reset operation, the timer circuit a9 first outputs the output from the central processing control circuit +1.
(The time it takes for output to be output to I will differ for each individual building. For this reason, after a long-term large-scale power outage is restored, the time it takes to report the equipment operating status at predetermined time intervals is The value will be different for each building.Therefore, even if a large-scale power outage occurs for a long time, it will be possible to prevent the reception center from being overloaded with reports at predetermined time intervals. After the first time, the equipment monitoring work is carried out the same as before, for example, every 24 hours, so there is no change in equipment monitoring work from before.

In the above embodiment, although an initial value setting circuit member is provided, the operations of one time limit circuit (1, telephone number storage circuit (13), building number storage circuit (14), central processing control circuit α, etc. are controlled by a program inside the computer). As for the processing performed, even if the operation on the initial value setting circuit side is added to the computer program processing, the intended purpose can be achieved in the same way as in the above embodiment.

In addition, although the initial value is determined based on the building management number, it may also be a value determined by a random number table or a value based on the 9th date, and the value may be different for each building. If so, the intended purpose can be achieved.

Yet again. In the above embodiment, a value corresponding to the building management number stored in the initial value setting circuit asFi building number storage circuit I is set as the initial value in the timer circuit α9. The initial value setting circuit uses the value set by the value setting switch as the initial value, and even if it is set to a time-limited circuit (US), it will be cumbersome to have to set the initial value to a different value for each building. However, the intended purpose can be achieved as in the above embodiment.

〔Effect of the invention〕

As described above, in this invention, different values are set for each building by external operation.

An initial value is set based on this value, and when a predetermined value is reached using this initial value as a starting point, a reporting means is activated to report information regarding the building equipment. Therefore, since the time at which the predetermined value is reached differs for each building, it has the effect that there is no concentration of one report.
