Abstract

The utility model relates to a wireless receiving device of fire hazard monitoring equipment, comprising a GSM (Global System for Mobile Communications) wireless transmitting and receiving circuit and a single-chip microcomputer control circuit; wherein an output signal of the GSM wireless transmitting and receiving circuit is controlled by the single-chip microcomputer control circuit and output to a communication interface circuit; and an output signal of the communication interface circuit is transmitted to a PC (Personal Computer) machine. The wireless receiving device of the utility model adopts the GSM wireless transmitting and receiving circuit to receive and transmit a digital signal, then the digital signal is decoded by a single-chip microcomputer and transmitted to the PC machine through a 485 bus, after that, a current state is displayed by a display system software of the PC machine, and alarm information can be transmitted to a designated person through a GSM module, thus the purpose of unmanned monitoring can be achieved, and the problems of difficult system wiring, and no regional limit for the alarm also can be solved, therefore, the wireless receiving device of the utility model has the advantages of realizing no man on duty, reducing engineering cost, etc.

Description

A kind of fire hazard monitoring equipment wireless receiving trap

Technical field

The utility model relates to the fire hazard monitoring field, particularly be a kind of fire hazard monitoring equipment wireless receiving trap.

Background technology

Electrical fire fire hazard monitoring equipment is used to receive the alerting signal of electrical fire detector; But traditional electric fire disaster monitoring equipment mainly is the alerting signal of application system bus pick-up probe; If indoor because of buildings, can destroy original structure after the wiring, will bring very big difficulty to construction.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of fire hazard monitoring equipment wireless receiving trap is provided.

The utility model solves the technical scheme that its technical matters adopted: a kind of fire hazard monitoring equipment wireless receiving trap; Comprise gsm wireless transmission circuit and single chip machine controlling circuit; The output signal of said gsm wireless transmission circuit exports communication interface circuit to through single chip machine controlling circuit control, and the output signal of communication interface circuit sends to PC.

Said single chip machine controlling circuit is also exported and is connected a voice alarm circuit.

Said communication interface circuit is for adopting the RS485 communication interface circuit of SN75176 signal transmitting and receiving chip.

Through adopting above-mentioned technical scheme, the beneficial effect of the utility model is: the utility model adopts GSM to send and the receiver module circuit, receives and send digital signal; After single-chip microcomputer decoding, pass to PC through 485 buses, show current state by PC display system software; Send warning message through gsm module to the designated person simultaneously; Reach the purpose of no worker monitor, solved that system wiring is difficult, reporting to the police does not have regional restriction, realizes advantages such as unattended, reduction engineering cost cost.
