Mine automatic drainage system based on Internet of things

The utility model provides a mine automatic drainage system based on the Internet of things. The mine automatic drainage system comprises a sensing layer, a network layer and an application layer. A liquid level sensor, a motor current sensor and a motor winding temperature sensor, a water pump shaft temperature sensor, a water pump outlet pressure sensor, a flow sensor, a valve open degree sensor and a vacuum sensor are arranged on the sensing layer. All the sensors are connected with an A/D collection module and then are connected with a main PLC, and an I/O module connected with the main PLC is connected with a control button, an electromagnetic valve, an electric brake valve, an electromagnetic driver, a high-voltage electric reactor and state indication lamps. According to the mine automatic drainage system, the defects that in the prior art, the function is singular, remote real-time monitoring can not be achieved, data management is irregular, wide-range networking and centralized controlling can not carried out are overcome, and centralized monitoring in an Internet of things type on key links like water wave information, device information and environment information of the mine automatic drainage system is achieved. A user can have access to a server of an centralized control center through a PC and the Internet or through a mobile phone, a PDA and other wireless terminals.
