With STC89C51 single-chip microcontroller.
In the present embodiment,
Further, the step of this method is as follows:
S1: gas collecting module 11 is measured in real time the gas in workshop, and it is right to be transmitted to D/A converter module 12
The gas signal of acquisition is amplified and is converted；
S2: main control single-chip microcontroller 21 receives the gas signal for being amplified and converting acquisition, and the gas signal of acquisition is passed
It transports to workshop display 22 to be shown, while main control single-chip microcontroller 21 judges the gas signal received, judges vehicle
Between various gas concentrations whether exceed threshold values；
S3: when every gas index without departing from threshold values when, continue to detect every gas concentration in workshop, when having
When one of them air pressure right angle exceeds threshold values, main control single-chip microcontroller 21 controls speech horn 311 and the energization of alarm lamp 312 is opened
It is dynamic, while alarm module 31 controls emergency evacuation channel electron door relay 32, exhaust relay 34 and fresh air relay 35 and opens
It is dynamic, started with controlling emergency evacuation channel electron door 36, scavenger fan 38 and fresh air fan 39, then 31 controlization of alarm module
Work production equipment relay 33 close, with control chemical production equipment 37 power off it is out of service；
S4: main control single-chip microcontroller 21 controls wireless generation module 23 and alarm signal is transmitted to wireless generation module 23, then
Alarm signal is transmitted separately to workshop responsible person's mobile phone terminal 24 and plant area's production safety monitoring room by module 23 wirelessly occurs
In terminal 25；
S5: camera 13 will shoot side workshop realtime video transmission to main control single-chip microcontroller 21, and main control single-chip microcontroller 21 will
Workshop transmission of video is to plant area's production safety monitoring room terminal 25, and then plant area's production safety monitoring room terminal 25 is by workshop video
Plant area's production safety monitoring display screen 26 is transmitted to be played in real time；
S6: it after to the malicious noxious gas emission in workshop, is generated according to the exceeded inspection of specific toxic and harmful gas
The chemical industry equipment and ventilation pipe of the toxic and harmful gas, and it is repaired or replaced.
In the present embodiment, the toxic and harmful gas concentration in workshop is detected by gas collecting module 11, and transmitted
It is poisonous and hazardous to avoid that the closing of chemical production equipment 37 is controlled to main control single-chip microcontroller 21 and by main control single-chip microcontroller 21
Gas continues to generate, while controlling scavenger fan 38 and fresh air fan 39 and arranging the air of the toxic and harmful gas contained in workshop
Out, safety standard is had reached, is then had again according to toxic and harmful gas type to generating or conveying the type by service personnel
Malicious pernicious gas is overhauled.
The working principle of the invention and process for using: after the present invention installs, by the first gas sensor 111, second
Gas sensor 112, third gas sensor 113, the 4th gas sensor 114 and the 5th gas sensor 115 are uniformly pacified
It is mounted in workshop in workshop, while by multiple groups camera 13, and guarantees that the picture that camera 13 is shot covers entire vehicle
Between, the first gas sensor 111, the second gas sensor 112, third gas sensor 113,114 and of the 4th gas sensor
5th gas sensor 115 can detect the toxic and harmful gas concentration in workshop, and be transmitted to D/A converter module
12, the gas signal acquired by 12 Duis of D/A converter module is amplified and is converted, and is then transmit to main control single-chip microcontroller 21, is connect
The every toxic and harmful gas concentration detected is judged by main control single-chip microcontroller 21, when the concentration of toxic and harmful gas
When greater than threshold values, main control single-chip microcontroller 21 controls alarm module 31 and starts, to issue alarm and evacuation egress signal, reminds vehicle
Between evacuating personnel withdraw workshop, while main control single-chip microcontroller 21 controls emergency evacuation channel electron door relay 32 and opens, and makes tight
Anxious fire escape electronic gate 36 powers on opening, allows plant personnel from urgent fire escape evacuation egress, improves thin
Efficiency is dissipated, while alarm module 31 controls chemical production equipment relay 33 and closes, so that the Chemical Manufacture controlled in workshop is set
Standby 37 power-off is out of service, so that toxic and harmful gas be avoided to continue to generate, then the control of main control single-chip microcontroller 21 exhaust after
Electric appliance 34 and fresh air relay 35 open simultaneously, so that outside air is discharged into workshop, either inside contains toxic and harmful gas
Air is pulled out in workshop, to realize the ventilation to workshop, while the exhaust pipe in workshop can be connected to chemical plant
The input terminal of waste gas treatment equipment avoids poisonous and harmful gas so that the poisonous and hazardous air being discharged in workshop be handled
The problem of body is expelled directly out, and causes environmental pollution, while alarm signal is transported to wireless generation module 23 by main control single-chip microcontroller 21,
And there is the wireless module 23 that occurs to be sent to workshop responsible person's mobile phone terminal 24, workshop responsible person is understood in workshop in time
Those of toxic and harmful gas it is exceeded, and make corresponding processing and record, at the same it is wireless occur module 23 by alarm signal and
The real time monitoring picture transmission in the workshop that camera 13 is shot is produced into plant area's production safety monitoring room terminal 25 by plant area
The display of security monitoring display screen 26 plays, when plant area production safety monitoring room can understand the situation of accident workshop generation in time,
And make corresponding emergency processing.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
