气力输送失效的原因与其控制系统关系密切，当电除尘等高压电网瞬间冲击时，单机PLC控制系统程序易走飞，造成堵管等故障．为此，我们开发了PLC双机热备控制系统，实现了全面的自动化控制和组态监控，并进行了实际运行和调试，实践证明，该系统能有效提高气力输送的稳定性和可靠性。

The causes of the failure in pneumatic conveying are closely related to its control system, wnen me elec-tric dust removal and other high voltage power grid are transiently impacted, some errors tend to occur in single PLC control system program, resulting in malfunctions including blocking the tube. Therefore, we developed PLC hot standby control system in order to achieve a comprehensive automation control and configuration monitoring, and the actual operation and debugging. It is proved that effectively improves the stability and reliability of the pneumatic conveying system.
