Gather the concentration data of pernicious gas；Extension set first is used to receive the data of sensor assembly collection and the data is carried out
Analyzing and processing, result is sent to digital display module and is shown and is passed data processed result by communication interface
Host computer control module is transported to, if it exceeds harmful gas concentration standard then controls ventilation warning device to be aerated and alarm.Pass
Sensor module is placed in detected gas back shop, and extension set first, digital display module and ventilation warning device are arranged at work
Make inside room, extension set first is by data by communications interface transmission to host computer control module, and host computer control module carries out judging to divide
Analysis, if harmful gas concentration is exceeded, host computer control module sends alarm command, the driving ventilation report of extension set first to extension set first
Alarm device is aerated and alarmed.
Further, sensor assembly includes gas sensor, modulate circuit and analog to digital conversion circuit, the gas sensing
Device, modulate circuit and analog to digital conversion circuit are sequentially connected, and the sensor assembly is connected by analog to digital conversion circuit and extension set first
Connect.Harmful gas concentration in gas sensor detection back shop, data are sent out by modulate circuit and analog to digital conversion circuit processing
Deliver to extension set first.
Further, gas sensor is at least provided with one.Multiple gas sensors can be set, increase the model of detection
Enclose.
Further, modulate circuit is identical with gas sensor number.
Further, host computer control module includes main control computer, display, keyboard, mouse and main frame warning device, described aobvious
Show that device, keyboard, mouse and main frame warning device are connected with main control computer respectively, the host computer control module is by main control computer with communicating
Interface is connected.The data that main control computer analysis is passed back from extension set first, judge leakage point, accelerate the speed of processing poisonous gas leakage
Degree, reduces loss.
The utility model compared with prior art, has the following advantages and advantages：The utility model sets multiple
Sensor changes the point detection in traditional detection mode, transforms it into region detection, expands the detection model of pernicious gas
Enclose, it is to avoid pernicious gas tiny leakage indiscoverable situation, accelerate the processing speed of poisonous gas leakage accident, it is to avoid
Casualties and larger economic loss.
