Novel duplicate-power double-fan intelligent monitoring protection device

Abstract

The invention discloses a novel dual-power dual-fan intelligent monitoring and controlling protection device which is an embedding-typed system comprising a micro-control processor; the device also comprises a data acquisition module, a serial communication module, an auxiliary hardware module, and a human-computer interactive module, so as to finish the tasks of data acquisition, protection judgment, fan control, serial communication and human-computer interactive processing and carry out continuous ventilation and state detection. By using two micro-computer intelligent monitoring and controlling protection devices, two fans which are respectively a host and an auxiliary machine, with the power being supplied by different power sources, are respectively controlled, so as to control the continuous work of the intelligent monitoring and controlling protection devices. The protection device not only can detect the current and voltage of the fans and protect the occurring fault in real time, but also can use complementary control strategy so as to ensure that a ventilation system can supply wind continuously, and therefore ensures the production safety of mines; the device also has the communication function, can be used as one function module of the electric automation system of the mines, and realizes the integration of functions such as dual-power dual-fan monitor, control, protection, communication, etc.

Description

technical field [0001] The invention relates to an intelligent measurement, control and protection device for dual power sources and dual fans, in particular to a device capable of realizing automatic monitoring, control and protection of dual power sources and dual fans. Background technique [0002] In the process of mine production, whether the ventilation system can work effectively is directly related to the safety of mine production. As the control unit of the ventilation system, dual power supply and dual fans are a more efficient and safer form of fan composition. The dual power supply and dual fan automatic switching device is the key equipment in the system, which is directly related to the safe operation of the entire system. Therefore, the rationality and reliability of the protection and control methods of the dual power supply and dual fan automatic switching device are crucial to its safe operation. At present, the intelligent dual-power dual-fan system base...

Problems solved by technology

At present, the intelligent dual-power dual-fan system based on embedded microprocessor control is still blank. Most of the dual-power dual-fan systems that have been in operation are controlled by PLC or relays, which have few functions, poor reliability, and low control accuracy, especially when accidents occur on site. Unable to automatically take emergency measures, seriously affecting the safe operation of the power grid and equipment
