Gas stations to lightning electrostatic the demand is higher, weak electrostatic signal interference in mixed gas, electrostatic ion of discrete concentration and movement speed are significant changes. Once the electrostatic charge is interference gas interference, happen charge discrete concentration change, the current detection system detection accu-racy will be decreased obviously. Therefore this paper puts forward a gas station lightning electrostatic detection system design method. By gas sensitive sensor equipment composition discrete concentration acquisition module, a temperature compensation way compensate error, using signal classification of software algorithm, the interference signal effectively re-move, the establishment of lightning risk prediction model, enhance system detection accuracy, overcome the disadvan-tages of traditional methods. The practice proved that this method can greatly reduce the gas station mixed gas to electro-static charge distribution of the interference, ensure the accuracy of the detection system, and achieved satisfactory re-sults.
