Abstract

PURPOSE:To execute efficiently a power source backup by providing a line for the power source backup between a central monitor board and a sensor unit, and executing a different power source backup in accordance with a power failure of only the center unit, and power failures of the whole device. CONSTITUTION:When a supply of a commercial power source is cut off with respect to one of sensor units GP, a switching device S2 of a housing information board GP brought to a power failure operates and closes a contact. In that case, in case a central monitor board CT is receiving a supply of a commercial power source normally, the power source is supplied to all the circuits through an emergent power source supply line PF1 and the monitoring state is maintained. In case the power failure extends on the whole device, a switching device S1 of the monitor board CT operates and closes the contact, and a power source is supplied from an emergent power source E. Also, a backup of the power source is executed only from an emergent power source supplying line PF2 by diodes D1, D2, the power source is supplied to only a fire receiving device AF by a diode D4 of the information board GP, and only this circuit maintains the monitoring state.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a central monitoring device for a residential complex, which is equipped with sensor units for disaster prevention and crime prevention in common households such as residential complexes, and centrally monitors from a central monitoring panel based on the transmitted signals of the plurality of sensor units. Regarding.

2. Description of the Related Art Conventionally, ordinary homes are equipped with sensors for detecting fires, gas leaks, etc., and there are sensor units that provide various indications and alarms for fires and gas leaks in each residence. Transmission signals are provided to output fire signals, gas leak signals, etc. from the sensor units to the outside, and information from a plurality of sensor units is centrally monitored by a central monitoring panel.

Normally, a plurality of sensor units and a central monitoring board each receive power from a commercial power source (AC10, OV). However, the sensor units installed in each home are often cut off from commercial power supply and are not equipped with an emergency power source, which is inconvenient for centralized monitoring.

In this invention, the central monitoring panel is equipped with an emergency power source, and a line for power backup is provided between the central monitoring panel and the sensor units, so that different power backup methods can be used in case of a power outage for the sensor unit or for the entire power outage. It was designed to be taken.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

The drawing shows a wiring diagram of the central monitoring device for apartment buildings according to the present invention. There is a central monitoring panel CT installed in the management room, etc., and a first one extending from this central monitoring panel CT to each residence.
．． Second emergency power supply line PFI/PF2. Common line C5 Fire signal line L, gas leak signal line G TJ, housing information board GP connected to these lines and installed in each house, and fire detector connected from this housing information board GP via the line. It consists of an FD and a gas leak detector GD. One sensor unit is composed of the housing information panel GP, the fire detector 5FD, and the gas leak detector GD. The central monitoring board CT has a power supply SPO that generates an appropriate circuit voltage from the commercial power supply, an emergency power supply E, and a 1 to 4 power supply in the event of a power outage.
A first screaming device S1 for closing the y point and supplying power from the emergency power source E, and a diode DLD2 for backflow prevention.
and a monitoring and alarm device AR that displays and issues alarms based on fire and gas leak transmission signals from the housing information board GP. The housing information panel GP includes a power supply device sp1 that generates an appropriate external circuit voltage from a commercial power supply, a second switching device S2 that closes the contacts when this power supply is turned off, and a diode D3 for backflow prevention. D4, a fire receiving device AP that displays and issues an alarm when the fire detector FD is activated, and a gas leak detector GD.
The gas leakage receiving device AG is equipped with a gas leakage receiving device AG that displays and issues an alarm during operation.

To explain the operation of the central monitoring system for apartment buildings configured in this way, normally the central monitoring board CT and the plurality of sensor units receive power from a nearby commercial power source, and are connected to separate power supplies SPO, The circuit power is supplied from SPI.

In such a situation, if the fire detector FD of any sensor unit detects the occurrence of a fire and operates,
Based on this signal, the fire receiving device A' of the housing information board GP
F displays the occurrence of a fire and issues an alarm to notify that a fire has occurred in this house, and also transmits a transmission signal to the monitoring and alarm device CT via the fire signal line. In this way, the central monitoring panels C and T and the central monitoring panel CT perform intensive monitoring by displaying and warning of gas leaks.

Here, if the supply of commercial power to any one of the sensor units GP is cut off, the second switching device S2 of the residential information panel GP that has experienced the power outage operates to close the contacts. Central monitoring board C
When T is normally supplied with commercial power, power is supplied to all circuits via the emergency power supply line PF1 and the monitoring state is maintained.

If the power outage extends to the entire area, the first switching device S1 of the central monitoring panel CT operates and closes the contacts, and power is supplied from the emergency power source E. Then, the power is pulled up only from the emergency power supply line PF2 by the diodes DI and D2, and the power is supplied only to the fire receiving device AF by the diode D4 of the housing information panel GP, and only this circuit maintains the monitoring state. This is not limited to the content shown in this embodiment, but is designed to maintain the minimum required functions of specific parts of each sensor unit in the event of a power outage in all cases.

This is because the emergency power supply E usually does not have enough margin to cover the power of all the circuits of all the sensor units for a long time.

As explained above, the present invention is equipped with an emergency power supply E in the central monitoring panel CT, and in the event of a power outage of only each sensor unit, all the power required for the sensor units is transferred to the central monitoring panel CT.
The system is powered up by the commercial power supply on the side, and in the event of a power outage, only the circuits that maintain the minimum required functions of each sensor unit are powered up. Therefore, the power outlet of the sensor unit was carelessly unplugged in each household.
