Abstract

The utility model relates to a standby power source detecting device, in particular to an electrical fire safety monitoring device. The electrical fire safety monitoring device comprises a temperature collection signal amplifying module, an A/D (analog-to-digital) converting module, a broken line collection triggering module, a central processor, a GSM (global system for mobile communication) short message receiving and sending module, and an electromagnetic valve driving control module, wherein the output terminal of the temperature collection signal amplifying module is output to the central processor via the A/D converting module; the output terminal of the central processor is connected with the GSM short message receiving and sending module and the electromagnetic valve driving control module; and output signals of the broken line collection triggering module are transmitted to the electromagnetic valve driving control module via the central processor. The device adopts a manner that a copper wire coil penetrating a plastic insulator is mounted in a position area needing to be monitored, and when a fire occurs and the fuse wire is burnt out, an electromagnet valve is driven to spray water and extinguish the fire through triggering a switching circuit; meanwhile, the GSM short message receiving and sending module sends alarm signals to a receiving host computer mounted in a duty room, so as to inform the working personnel to timely extinguish the fire at the first time, and ensure the life property safety of people.

Description

The electrical fire safety monitoring device

Technical field

The utility model relates to a kind of standby power supply pick-up unit, particularly be a kind of electrical fire safety monitoring device.

Background technology

Along with deepening continuously of reform and opening-up, the improving constantly of people's living standard, office space and inhabitation residence design aspect are perfect inadequately, in case the breaking out of fire loss is huge.When fire took place, particularly just on fire at the large space floor, smoke detector and heat detector did not all detect signal, in the time of can not sending alerting signal, the fire extinguishing of fire bud were let slip a golden opportunity.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electrical fire safety monitoring device is provided.

The technical scheme that its technical matters that solves the utility model adopts is: the electrical fire safety monitoring device, comprise temperature acquisition signal amplification module, A the D modular converter, broken string trigger collection module, central processing unit, GSM short message transceiving module and solenoid-driven control module, the output terminal of described temperature acquisition signal amplification module through A the D modular converter be input to central processing unit, connect GSM short message transceiving module and solenoid-driven control module by central processing unit output, the output signal of described broken string trigger collection module transfers to the solenoid-driven control module through central processing unit.

Described temperature acquisition signal amplification module adopts K type temperature sensor collecting temperature signal.

The output signal of described temperature acquisition signal amplification module is amplified through the AD623 operational amplifier.

Described broken string trigger collection module adopts the copper wire coil of putting in the plastic insulation to live to need guarded region, and forms trigger switch by copper wire coil output connection resistance and transistor.

Described central processing unit is a single-chip microcomputer.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: put on the copper wire coil in this device employing plastic insulation and live to need the monitoring position zone, when fire generation blowout, by the trigger switch circuit working, drive electric valve sprinkling fire, send alerting signal by GSM note wireless transceiver circuit to the reception main frame that is installed in duty room simultaneously, notify the staff breaking out of fire dangerous situation, thereby in time, guarantee people's security of the lives and property in very first time fire extinguishing.
