Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for notifying the outside of an abnormality inside a building.

In the signal conversion circuit 0, the telephone number of the monitoring center αO stored in the dial destination storage device (b) is automatically dialed by the loss control circuit, and the signal transmitter (b) - changeover switch wire → network control circuit. (A) - The division is the device (A) - Military 1st telephone line (7) - through the route of the end (8) - Telephone line (9),
Call the telephone of the monitoring center αO. After the line is connected, the above-mentioned abnormal signal is then transmitted through the above-mentioned route.

When the elevator of Unit 1 breaks down, the fault detection contact (15
A) is closed. Here, when the emergency call button (14A) is pressed in the car (2 people), an abnormality signal (31a) is issued via switch 01), and the fault is stored through the converter) and OR gate 0. The signal is stored in the device (2) and sent to the signal conversion circuit 00. Here, when the line is automatically dialed and the line is connected as described above, the signal conversion circuit θQ sends a signal to the changeover switch (e), and the changeover switch (e) is connected to the contact (a) side. At this time, a transmission/reception signal for the call is emitted from the monitoring center aO, and is applied to the connector (a) through the signal receiver (7) and the signal conversion circuit 00, and the transmission/reception changeover switch (55) is switched to the terminal (a) or the terminal ( b). In other words, switching between transmitting and receiving is performed f'
L. In the transmitting state, the voice from the intercom (13A) is transmitted via the transmitting amplifier (53A) - the transmitting/receiving selector switch (55) - the circuit constant adjuster (56) - the selector switch wire → the network control circuit (A). Transferred to telephone line (7), monitoring center 0
A call is made to telephone number 0. Also, in the receiving state,
The transmission/reception switching signal from the monitoring center 00 is sent to the signal receiver (to)
The signal passes through the signal converter θ0, is decoded, and the transmission/reception changeover switch (55) of the connector (c) is switched. Then, the voice from the monitoring center is routed through the network control circuit (a) - changeover switch - circuit constant adjuster (56) -> transmission/reception changeover switch (55) -> incoming call increaser IM unit (54A). ). During this call, when an abnormality signal is emitted from the failure detection device (3+, (4) and the abnormality detection contact (5), a signal is sent from the side of the signal conversion circuit 0 to the changeover switch handle, and the changeover switch handle is connected to the terminal ( The switch is switched to the hu terminal (a) side and the communication device (13A) is disconnected.Then, an abnormal signal is sent to the monitoring center.When the transmission is completed, the changeover switch is switched to the hu terminal (a) side again. , the telephone set (13A) is connected to the line.

The telephones (13A) and (13B) are designed to be able to communicate with the telephone in the manager's room in the building (1) during normal times. At this time, leave switch 0◇ open. required by the manager,
When you will be away due to returning home, etc., close switch 0]).
As mentioned above, the emergency call button (14A) is located within the handle (2A) and (2B).

When (14B) is pressed, the telephone is automatically connected to the monitoring center αO.

The failure detection scanning circuit (incorporated) sends an address signal (33a) to the address line and constantly scans for abnormality signals. The failure detection circuits αQ and αη detect failures in each of the equipment in the building. For example, failure detection circuit α
The output from Q is input to timers (18A) to (18N) and output at different times. The address decoder (a) receives an address signal (33a). When the address matches its own address, its output becomes rHJ, and the AND gates (21A) to (21N) are opened. Now, the outputs of the timers (18A) to (18N) are outputted through the AND game (21A) to (21N). The same applies to the failure detection device (4). AND game) (22A) ~ (22N), (23A)
The outputs of (23N) are placed on the same data line, inputted as data signals DA and DN to the failure detection scanning circuit 03, and sent to the monitoring center 00 in the same manner as described above.

The periodic alarm timer (a) activates the signal conversion circuit θ at predetermined time intervals.
Sends a signal to Q to request a scheduled alarm. The signal converter circuit then automatically dials as described above and sends predetermined data to the monitoring center 0Q. This data is taken in from the control and monitoring device αυ by the data collection circuit, stored in the fault storage device, and sent to the signal conversion circuit. When the above data is sent to the monitoring center 01, a control signal transmitter # (not shown) in the monitoring center αυ
From there, control signals for equipment in the building (1) are transmitted as necessary. The signal conversion circuit 00 waits for return data consisting of the control signal, and if there is return data, it receives it and stores it in the return data storage device Q71. After the line is disconnected, the returned data is sent to the control and monitoring device αυ, and the building (
1) The equipment is automatically controlled.

The fault data is stored in the fault storage device (c), but a plurality of its contents are grouped and sent as the outputs of OR gates c, while the others are sent as they are to the respective display devices (g).
Is displayed.

Further, the building number stored in the building number storage device #(b) is always sent out each time an alarm is issued, as it specifies the building to which the building belongs.

It is also possible to perform snoring as follows.

(7) Using batteries, all or some of the components of the abnormality notification device (6) can be used even when the parking lot is stopped.

(b) Address signals and data signals between each device are transmitted through a predetermined number of address lines and data lines, respectively.
However, this is converted into a serial signal (for example, ν0 is an asynchronous type) and transmitted and received. Also, at this time, serial transmission by modulation and demodulation is performed.

(1) Use a light bulb, numeric display, cathode ray tube, etc. as the display (c).

b) Half-duplex transmission is performed by switching between the signal receiver (g) and the signal transmitter (b), but full-duplex transmission is performed using, for example, signals of different frequencies.

(2) A switch, ROM (read-only memory), or RAM with battery as a storage device for the building number and dial destination.
