Problems solved by technology

[0002] There are a large number of motors used in the parking equipment, and each motor can be equipped with a frequency converter for closed-loop control, but this will greatly increase the cost of the equipment. If one frequency converter is connected to multiple motors for open-loop control, it is impossible to monitor the performance of each motor. The running state, especially the inability to control whether the actual release and closing state of the motor brake is synchronized with the output signal of the frequency converter, has a great potential safety hazard

Abstract

The invention provides a three-dimensional garage frequency conversion and speed regulation control system with a brake monitoring function. The system comprises a power supply, a PLC control unit, a contactor, a frequency converter and a current-controlled relay detection feedback unit K4. According to the three-dimensional garage frequency conversion and speed regulation control system with the brake monitoring function, a single frequency converter is used for conducting open-loop control on multiple motors; meanwhile, a current controller is used for monitoring a working current of a target motor brake and feeding back monitoring information to the PLC control unit to conduct comprehensive judgment, and therefore synchronous action of the motor brake in the open-loop control process of the frequency converter is effectively guaranteed.

Description

technical field [0001] The invention relates to a control system of parking equipment, in particular to a three-dimensional garage frequency conversion speed regulation control system with brake monitoring. Background technique [0002] There are a large number of motors used in the parking equipment, and each motor can be equipped with a frequency converter for closed-loop control, but this will greatly increase the cost of the equipment. If one frequency converter is connected to multiple motors for open-loop control, it is impossible to monitor the performance of each motor. The running state, especially the inability to control whether the actual release and closing state of the motor brake is synchronized with the output signal of the frequency converter, has great potential safety hazards. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a real-time monitoring, safe and reliable three-dimensional gar...
