Problems solved by technology

The split-line alarm system technology is relatively mature, but it cannot meet the multi-node and large-scale detection requirements; the bus-type alarm system can not only solve the above problems, but also facilitate management
At present, the bus-type alarm system mostly adopts the RS-485 bus mode, but the node capacity of this type of system is not large and the system is unstable

Abstract

The invention discloses a gas alarm which comprises a detector module used for acquiring the concentration information of combustible gas on a detected site and conducting analog-digital conversion on the concentration information, a main controller used for receiving output signals of the detector module and controlling a pipeline valve and a fan valve through a relay set, and a power supply module, wherein the detector module is connected with the input end of the main controller through a CAN bus module, the relay set comprises a first relay and a second relay which are both connected with the main controller, the first relay is connected with the pipeline valve, the second relay is connected with the fan valve, a key input module is connected to the input end of the main controller, a display module and an audible and visual alarm module are connected to the output end of the main controller, and the main controller is in communication with an upper computer through an Internet interface module. The gas alarm is good in stability, safe, reliable, high in node capacity, convenient to maintain, good in anti-interference performance, and convenient to promote and use.

Description

technical field [0001] The invention relates to a gas alarm. Background technique [0002] With the development of society, the relationship between gases and humans is getting closer. There are many kinds of gases, among which harmful gases have seriously affected people's work and life. In order to ensure the safety of people's lives and properties, and the pace of urbanization is getting faster and faster, residents are using more and more gas, and gas safety testing is becoming more and more important. , the alarm is more and more popular because of its safety, reliability, and convenient operation. At present, the alarm system on the market can be divided into two types: split line type and bus type. The split-line alarm system technology is relatively mature, but it cannot meet the multi-node and large-scale detection requirements; the bus-type alarm system can not only solve the above problems, but also facilitate management. At present, the bus-type alarm system mo...
