Problems solved by technology

As the degree of automation in various fields is getting higher and higher, the scenarios of multi-motor and multi-equipment working together are also increasing day by day. The existing motor protectors cannot realize multi-machine cooperative work, and an additional controller is needed to realize it.
Increasing the controller will inevitably increase the cost and make data communication cumbersome

Abstract

The invention discloses a programmable control motor protector, which includes a power supply module, a display module, an IO module and a CPU main control board; the CPU main control board includes a sampling unit, a logic control unit, and an extended communication interface. The unit obtains the motor protection setting parameters provided by the display module, the system voltage, current and leakage resistance data provided by the sampling unit, and the external control switch signal provided by the optocoupler isolation input unit, and outputs according to the pre-input logic control program Motor protection control signal and system logic control signal, and then realize motor protection control and system logic control. The programmable control motor protector provided by the present invention adds a logical control function for multiple motors or other executive devices to work together on the basis of the original motor protector, reducing the cost of additional controllers. Based on the programmable control motor protector, the present invention also provides a winch dispatching system and method in a mine.

Description

technical field [0001] The invention relates to the technical field of motor protectors, in particular to a programmable control motor protector and an underground winch scheduling system and method using the programmable control motor protector. Background technique [0002] The function of the motor protector is to protect and control the motor, and disconnect the motor in the event of overcurrent, undercurrent, phase failure, stall, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, etc. The main circuit circuit is used to realize the purpose of protection and the aging of the winding to give an alarm or protection control. [0003] In the prior art, the motor protector mainly reads the operating data of the motor through current transformers, transformers and other conversion equipment, and the single-chip microcomputer realizes the protection of the motor through the calculation of the collected data. As the degree of automation in v...
