Alarm system suitable for detecting hazardous gas

Abstract

The invention relates to an alarm system suitable for detecting hazardous gas. The alarm system comprises front-end monitoring equipment, and the data transmission port of the front-end monitoring equipment is connected with rear-end monitoring equipment. The alarm system is characterized in that the front-end monitoring equipment comprises an equipment box, a data processing board is arranged in the equipment box, the data processing board is provided with a plurality of data communication interfaces, and the data communication interfaces are respectively connected with a control assembly, a front-end transceiving device, a detection device, an alarm device and an electromagnetic valve. Meanwhile, the rear-end monitoring equipment comprises an energy supply device, and the energy supply device is connected with a linkage control driver, a rear-end transceiving device and an exhaust device. Thus, the alarm system can meet field monitoring and realize remote monitoring at the background at the same time. Moreover, the front-end transceiving device and the rear-end transceiving device are formed by modularized structures, so that effective data communication is realized. In the presence of the exhaust device, harmful and hazardous gas can be exhausted in time, thus ensuring field safety.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an alarm system suitable for dangerous gas detection. Background technique [0002] Combustible gas is widely used in modern society. Whether it is industrial gas or household gas, gas is closely related to people's life and is inseparable. With the development of the petrochemical industry, the types and scope of use of flammable and explosive gases have increased. Once these gases leak during production, transportation and use. When mixed with air, it will cause a fire. Once the concentration reaches the explosion limit, it will cause an explosion accident, seriously endangering people's lives and property safety. Due to the diffusibility of the gas itself, after leakage, the combustible gas will spread rapidly along the ground surface under the action of external wind force, forming a combustion explosion or poisoning dangerous area, and expanding the harmful area. This type of accide...

Problems solved by technology

Therefore, the existing hazardous gas alarm verification measures and maintenance measures have great potential safety hazards. In response to this potential safety hazard, we have carried out the research and development of remote calibration technology for hazardous gas alarms, which has greatly improved the existing hazardous gas alarm technology. It can be widely used in gas, petroleum, chemical industry, metallurgy, catering and other dangerous places with flammable, explosive and toxic gases. It has a very broad application prospect and is the key to realize safe production Strong technical support
