Alarming method of flammable gas, device and equipment

Abstract

The invention belongs to the security technical field and provides an alarming method of flammable gas, a device and equipment; the method comprises the following steps: early warning threshold value corresponding to the flammable gas concentration value under unusual condition is obtained; the obtained early warning threshold value is stored; the flammable gas in the present environment is obtained when the flammable gas is detected; according to the stored early warning threshold value, the flammable gas under the present environment is analyzed, when the alarming condition of the early warning threshold value is met, the alarming is carried. In the invention, the early warning threshold value corresponding to the gas concentration value under unusual condition is stored, the flammable gas under the present environment is analyzed according to the stored early warning threshold value when the flammable gas under the present environment is detected, if the flammable gas under the present environment is accordance to the alarming condition corresponding to the early warning threshold value, so as to carry out alarming, be capable of setting the early warning threshold value scientifically and automatically, improve the alarming accuracy, greatly eliminate the unnecessary safety hazards and completely eradicate the safety hazards.

Description

technical field [0001] The invention belongs to the field of security technology, and in particular relates to a combustible gas alarm method, device and equipment. Background technique [0002] With the continuous improvement of people's safety awareness, users' requirements for security products are also getting higher and higher. [0003] In the field of gas monitoring, combustible gas detectors are popular among users because of their mature technology, low cost and stable performance. [0004] The basic principle of the combustible gas detector is to sense the external gas concentration information, convert it into the corresponding voltage signal amplitude, and compare it with the preset voltage signal amplitude of the alarm at the nominal concentration to achieve the purpose of alarm. [0005] Combustible gas detectors generally use semiconductor gas sensors, which are composed of heating electrodes, output electrodes and sensitive materials coated in between. The h...

Problems solved by technology

[0007] In the existing technology, some small enterprises may directly set production based on experience due to the uneven technical equipment, and large-scale factories still cannot avoid the traditional method of manually adjusting the alarm point

The above method of setting the alarm point will inevitably lead to the disadvantages of large differences in the alarm value set by the factory and poor consistency.
