Embodiment Construction

[0013] Such as figure 1 , 2 As shown, a new type of driving speed regulation system and method of a hybrid sorter based on the PID algorithm, including: a proximity sensor for collecting the arrival signal of each section of the trolley,

[0014] PLC, used to receive the proximity sensor signal and calculate the current speed of the car,

[0015] The frequency converter is used to receive PLC signals and control the operation of multiple linear motors.

[0016] The control method includes the following steps: the trolley passes through the proximity sensor during operation, the proximity sensor senses the axis of the walking wheel and feeds back the signal to the PLC, and the actual moving speed of the trolley is calculated in the PLC according to the feedback signal and the fixed distance between the trolleys Vr, compare the calculated actual moving speed Vr with the moving speed Vs set by the system;

[0017] When Vr-Vs>0, reduce the frequency of the inverter and reduce t...

Abstract

The invention discloses a novel driving speed regulation system and method of a hybrid sorting machine based on a PID algorithm. The system comprises a proximity sensor used for collecting in-place signals of each section of the trolley, a PLC used for receiving the signals of the proximity sensor and calculating the current speed of the trolley, and a frequency converter used for receiving the signals of the PLC and controlling a plurality of linear motors to operate. The control method comprises the following steps: the trolley passes through the proximity sensor in the running process; theproximity sensor senses a shaft of the walking wheel and feeds back a signal to the PLC, the actual moving speed Vr of the trolley is calculated in the PLC according to the feedback signal and the fixed distance of the trolley, and the calculated actual moving speed Vr is compared with the moving speed Vs set by the system; and when Vr-Vs is larger than 0, the frequency of the frequency converteris reduced, the speed of the linear motor is reduced, Vr-Vs is equal to 0, the frequency of the frequency converter is kept, the speed of the linear motor is kept, and Vr-Vs is smaller than 0, the frequency of the frequency converter is increased, and the speed of the linear motor is increased.

Description

technical field [0001] The invention relates to the technical field of separators, in particular to a new driving speed regulation mode of a hybrid sorter based on a PID algorithm.
