Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator peripheral signal simulation system. Background technique [0002] In the current industry, the elevator position signal is obtained by the analog voltage value of the motor through the AD circuit, and the voltage value is transmitted to the ARM processor, and the ARM calculates the frequency division coefficient according to the algorithm, and transmits it to the CPLD through the data bus, and the CPLD outputs according to the frequency division coefficient. Encoder A, B phase pulse signal, A, B phase can be changed according to the needs of the elevator control board. The CPLD counts the output pulses, and sends them back to the ARM for processing through the data bus, and the ARM triggers the relay according to the number of pulses, so that the hoistway signals such as upper leveling and lower leveling can be simulated. That is to say, in the above method, the m...
