Abstract

A gas alarm device based on FPGA is provided, and the device comprises a gas concentration acquisition module, a wireless transmit-receive module and a core control module; the gas concentration acquisition module and the core control module both comprise a FPGA module; and the gas alarm device can transmit onsite gas leakage alarm signals to a mobile phone user, and alarming is carried out, and the device is reliable, timely and accurate.

Description

A kind of gas alarm device based on FPGA

Technical field

The utility model relates to a kind of warning device, especially a kind of gas alarm device based on FPGA.

Background technology

Traditional gas alarm device adopts the type of alarms such as alarm bell or phone more, when dangerous situation occurs, reports to the police by jingle bell etc.The characteristics such as this warning device cost is low, simple in structure, safe and reliable.But when the family personnel stay out, can't with the dangerous situation situation at scene accurately and timely pass to house-owner, these all cause the traditional alert device to be difficult to promote.

Summary of the invention

The purpose of this utility model just provides a kind of gas alarm device based on FPGA, and this warning device even house-owner stays out, also can allow house-owner in time recognize reliably field condition when dangerous situation occurs, and in time removes the dangerous condition.

The utility model is realized by following manner: a kind of gas alarm device based on FPGA, and this device comprises gas density acquisition module, radio receiving transmitting module and kernel control module; It is characterized in that: the gas density acquisition module comprises gas concentration sensor and a FPGA module; Kernel control module comprises post-controlled module, GPRS module and PC; Post-controlled module comprises the 2nd FPGA module; Described gas concentration sensor collection in worksite gas density, store gas density safety standard numerical value in the FPGA module in the gas density acquisition module, FPGA module in the gas density acquisition module compares gas density and the described standard figures of collection in worksite, if the gas density of collection in worksite is higher than described standard figures, FPGA module in the gas density acquisition module passes to radio receiving transmitting module with alerting signal, radio receiving transmitting module sends to post-controlled module with alerting signal, the alerting signal by the radio receiving transmitting module transmission that the 2nd FPGA module in the post-controlled module will receive passes to PC, after PC carries out alerting signal filtering and processes and control alerting signal after the GPRS module will be processed and send to user mobile phone and report to the police.

Burglar alarm of the present utility model is simple in structure, is convenient to install, can be in time, reliably dangerous situation is reported to the user, avoided user's property loss.
