Abstract: Based on the field situation of Pingshuo East Open Pit Mine, the drainage control system platform of Pingshuo East Open Pit Mine is established by comparing and choosing wireless bridge communication mode; the system database is established by using the steady and high precision liquid level sensor and process level wireless controller to collect the pump state data and intelligently control the start and stop of the pump so as to realize remote unattended intelligent control, real-time monitoring, historical data query, fault alarm and other functions. The drainage control system platform of Pingshuo East Open-pit Mine based on wireless network bridge has become an intelligent system for open-pit mine production.
