Embodiment 1

[0019] Such as figure 1 As shown, the system with gas leakage alarm function includes a detection module, an exhaust device, an alarm module, and a control module. The detection module includes an acquisition module and an analysis module. The acquisition module collects air samples and transmits them to the analysis module. The analysis module detects The gas concentration of the air sample is generated and the detection result is sent to the control module; the exhaust device includes an exhaust window installed on the wall and an exhaust fan arranged outside the wall. An air duct is arranged between them, and a solenoid valve is arranged on the air duct; an absorption device is also included, and the absorption device includes a storage box, an air intake duct, an air intake fan, and an air outlet duct, and the crystal of methylene blue is arranged in the storage box , the air intake fan communicates with the storage box through the air intake pipe, and the air outlet pipe ...

Embodiment 2

[0022] On the basis of Embodiment 1, it also includes a numbering module with a unique identifier, a wireless transmission module, and a management center. When the control module generates alarm information, the numbering module is activated, and the numbering module provides position information and transmits it to the control module. The control module sends the alarm information and location information to the management center through the wireless transmission module. The control module activates the numbering module, and the numbering module provides preset location information and transmits it to the control module. The control module transmits the alarm information and location information to the management center through the wireless transmission module, so that the management personnel of the management center can find the alarm situation in time and take rescue measures. measure.

Embodiment 3

[0024] On the basis of embodiments 1 and 2, it also includes a host computer and a GPRS module, and the host computer is used to receive alarm information and location information sent by the management center through the GPRS module. When the management personnel of the management center are not on site, the management center will transmit the information to the upper computer through the GPRS module when receiving the alarm information and location information, so that the management personnel of the management center can receive the alarm information and location information at the first time.

Abstract

The invention discloses a system with a coal gas leakage alarm function. The system comprises a detection module, an exhaust device, an alarm module and a control module, wherein the detection modulecomprises an acquisition module and an analysis module, the acquisition module acquires an air sample and transmits the air sample to the analysis module, and the analysis module detects the gas concentration of the air sample, generates a detection result and sends a detection result to the control module; and the exhaust device comprises an exhaust window arranged on a wall body and an exhaust fan arranged outside the wall body, a ventilation pipeline is arranged between the exhaust window and the exhaust fan, and an electromagnetic valve is arranged on the ventilation pipeline. The system further comprises an absorption device, wherein the absorption device comprises a storage box, an air inlet pipeline, an air inlet fan and an air outlet pipeline, a methylene blue crystal is arranged in the storage box, the air inlet fan is connected with the storage box through the air inlet pipeline, and the air outlet pipeline communicates with the storage box. The source is completely eradicated, and the gas concentration is reduced.

Description

technical field [0001] The invention relates to gas leakage, in particular to a system with gas leakage alarm function. Background technique [0002] The main components of gas are CO, hydrogen and alkanes, olefins, aromatics, etc. The gas content of CO and hydrogen in different cities may vary greatly. Gas is poisonous because CO and aromatic hydrocarbons in it can combine with hemoglobin in the human body to cause hypoxia, make people unconscious or even die, and even cause dizziness, nausea and collapse at low concentrations. Because CO gas is poisonous, the so-called gas alarm is judged as an alarm by detecting the leaked CO gas concentration. [0003] A gas leak can cause death by suffocation. The air that people live on has about 20% oxygen. If your activity space is a closed space with thin oxygen, you will have insufficient oxygen, suffocation, coma, and people with cardiovascular and cerebrovascular diseases will be life-threatening. In a closed space, gas leaka...
