Gas alarm controller

Abstract

The invention discloses a gas alarm controller, which comprises a touch display screen, an outer shell, a cursor upper moving key, a confirmation key, a cursor lower moving key, a menu key, an escapekey, a power indicator lamp, a low-alarm indicator lamp, a high-alarm indicator lamp, a channel indicator lamp, a loudspeaker, a gas concentration detector, a standby independent power supply, an MCUintelligent chip, and heat dissipating holes. The gas alarm controller has the beneficial effects that static electricity in the touch operation implementation process is effectively prevented throughthe outer shell; through the power indicator lamp, it is ensured that operating personnel can macroscopically grasp the electric quantity of a main power supply, and the operating personnel conveniently replace the main power supply in time; the different gas concentration indexes are distinguished through the low-alarm indicator lamp and the high-alarm indicator lamp, and different alarming is generated according to gas with the different concentrations; through the loudspeaker, it is ensured that alarm sound is large enough, and potential safety hazards are reduced; through the standby independent power supply, it is ensured that an alarm can work normally when the electrical quantity of the main power supply is used up; and through the heat dissipating holes, it is ensured that internal continuous heat dissipation can be achieved when the processed information quantity is large, and the safety of internal elements is ensured.

Description

technical field [0001] The invention relates to an alarm controller, in particular to a gas alarm controller, which belongs to the technical field of gas detection and control. Background technique [0002] In the fields of petroleum, chemical industry, thermal power, nuclear power, metallurgy, gas, municipal, commercial services, storage and other industries, there is the possibility of generating methane, hydrogen sulfide, carbon monoxide, oxygen and other gases at any time. Some of these gases may burn and explode. Some directly endanger the lives of people, so real-time monitoring and data management of these gases must be carried out. At present, point-type gas detectors are usually used in the fields of these industries, which are fixed in various areas of the scene. If the above-mentioned gases leak, and When the concentration reaches a concentration that can be combustible and explosive, and harm people's health, the gas detector will alarm in time, and people will q...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, there are many gas alarm controllers on the market. However, the existing gas alarm controllers have some minor problems. First, they cannot effectively prevent emergencies, such as the main power supply is exhausted, and the alarm cannot work normally. Second, use a single buzzer to alarm, and the sound is not loud enough. Third, the outside of the display screen should be pasted with plastic film buttons on the cover. After a long time, the glue will fall off, and the display screen sometimes fails the electrostatic test. Fourth, when processing a large amount of information, the internal heat dissipation effect is not obvious
