Problems solved by technology

[0003] At present, the test of the elevator control board before leaving the factory requires on-site simulation by using motors, encoders, PLCs, etc. Due to the large size of the motors, debuggers and other equipment, complex wiring, it is difficult to maintain when a fault occurs, and pure manual testing cannot respond objectively. Problems in the program, sometimes judged by experience
Due to incomplete testing, the failure rate of products sent to the field is high and the maintenance cost increases

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0019] Depend on figure 1 Visible: the present invention is realized through the following steps:

[0020] The analog voltage value of the motor is obtained through the AD circuit, and the voltage value is transmitted to the advanced RISC microprocessor;

[0021] The advanced RISC microprocessor calculates the frequency division coefficient according to the algorithm, and transmits it to the complex programmable logic device through the data bus;

[0022] The complex programmable logic device outputs the A and B phase pulse signals of the encoder according to the frequency division coefficient, and the phases of A and B phases are changed according to the needs of the elevator control board;

[0023] The complex programmable logic device counts the output pulses and sends them back to the advanced RISC microprocessor for processing through the...

Abstract

A method for simulating the shaft of elevator includes such steps as using AD circuit to obtain the analog voltage value of motor, transmitting it to ARM processor, calculating frequency dividing coefficient, transmitting it to CPLD via data bus, outputting the phase-A and phase-B pulse signals, counting the pulses, transmitting the counted value back to ARM processor via data bus, and triggering the relay to simulate the signals of said shaft of elevator.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a method for simulating an elevator shaft. Background technique [0002] The movement of the elevator up and down the shaft is mainly controlled by the elevator control board. Its main functions are responsible for the operation of the elevator, managing the frequency converter, giving the speed curve, and monitoring the status of the elevator. [0003] At present, the test of the elevator control board before leaving the factory requires on-site simulation by using motors, encoders, PLCs, etc. Due to the large size of the motors, debuggers and other equipment, complex wiring, it is difficult to maintain when a fault occurs, and pure manual testing cannot respond objectively. Problems in the program are sometimes judged entirely by experience. Due to incomplete testing, the failure rate of products sent to the field is high, and the maintenance cost increases. [0004] current technolo...
