Abstract
The utility model discloses a tower crane monitoring system with a self-locking function, which comprises a tower crane sensor, a PLC (Programmable Logic Controller), a relay and a contactor, wherein the relay and the contactor are arranged at a main circuit power supply of a tower crane motor. The tower crane sensor is directly connected with the PLC through an AI (Artificial Intelligence) expansion module, and the PLC is respectively connected with the relay and the contactor. The tower crane monitoring system has the advantages that (1) when violations, operation troubles, manmade sabotage and the like occur, a fault diagnosis module can send out an alarm signal and sends a fault output signal into the PLC, and then the PLC can send out a control signal to stop working of a tower crane; (2) the tower crane monitoring system conducts the fault diagnosis and forecast for the operating of a construction crane, so that the safe production is brought forward onto the level of safe protection; (3) when the sensor-detected data of the height, angle, drawing force and the like of the tower crane exceed the limits, the tower crane monitoring system can send out alarm and automatically lock the information of the tower crane; and (4) multiple processors cooperatively work.
