The invention relates to a gas monitoring system based on a Zigbee network. The gas monitoring system comprises Zigbee wireless monitoring nodes used for monitoring gas-related devices in real time, a Zigbee coordinator and a control host. Each Zigbee wireless monitoring node comprises a gas sensor module and a Zigbee terminal module. The Zigbee coordinator is in wireless communication with the Zigbee wireless monitoring nodes so as to collect the collected data uploaded by the Zigbee wireless monitoring nodes. The control host is in communicated with the Zigbee coordinator and comprises a data memorizer, a fault alarm, a safety relay and a microprocessor. The microprocessor triggers the fault alarm to give out an alarm when the gas concentration in the collected data obtained through analysis exceeds the preset gas concentration threshold value, and controls the safety relay to turn off the corresponding gas-related devices. Compared with the prior art, the gas monitoring system based on the Zigbee network has the advantages that the self-organized network characteristics of the Zigbee and the self-diagnosis and redundancy fault-tolerant functions of the safety relay are fully utilized, safe and reliable control over workshop equipment is achieved by combining the advantages of the Zigbee network and the advantages of the safety relay, and the safety of the working environment of a workshop is improved.
Description
technical field [0001] The invention relates to a gas monitoring system, in particular to a gas monitoring system based on Zigbee network. Background technique [0002] In modern industrial production, with the complexity of the production process, the equipment in the factory workshop is becoming more and more complicated, and the safety of industrial production is getting more and more attention. In the process of gas production and transportation in the factory workshop, once a certain If the equipment does not work normally (failure), such as gas leakage during the gas transmission process, dangerous events such as fires and explosions in the factory workshop may occur, which will cause disastrous consequences to personnel, equipment or the environment. [0003] Based on the importance of safety in industrial production, many companies have adopted gas monitoring measures. Most of the traditional gas monitoring measures are connected and monitored by wires. This monitor...
