Remote keying method and device for stepper motor driver based on can communication

Abstract

The invention relates to the remote key control of a stepping motor driver, and particularly relates to a remote keying method and a remote keying device of the stepping motor driver based on CAN (Controller Area Network) communication. The device comprises a key, a control end signal processor, a CAN communication network and a controlled end signal processor, wherein the key is connected with the control end signal processor, the control end signal processor processes key signals as 'pressed down' or ' lifted up' code signals and sends the 'pressed down' or ' lifted up' code signals to the CAN communication network, and the controlled end signal processor receives the 'press down' or 'lifted up' code signals sent from the CAN communication network, decodes, synthesizes and restores the 'press down' or 'lifted up' code signals as the key signals, generates control signals and sends the control signals to the stepping motor driver. The remote keying device of the stepping motor driverbased on CAN communication successfully achieves manual remote keying of an antenna of a large-power long-wavelength signal transmitter, realizes a control distance as long as several kilometers, totally satisfies the demand of the manual remote keying of the antenna regulation of the large-power long-wavelength signal transmitter, ensures stable application in a large-power high-frequency field high-interference environment, and has good effect.

Description

technical field [0001] The invention relates to a remote key control of a stepping motor driver, in particular to a remote keying method and device for a stepping motor driver based on CAN communication. Background technique [0002] Due to the relationship between the working frequency of the high-power long-wave transmitter, the variable inductance coil in the tuning and filtering circuit is very large. Current, phase, etc., these ammeters have indications at all levels of signal flow), and after comprehensive consideration, determine the tuning position of the variable inductance coil (by changing the position of the short-circuit contact or changing the coupling angle of the tuning coil). The early variable inductance coils are tuned by manually rotating the input end (worm) of the mechanical device (worm gear) connected to the short-circuit contact or tuning coil. This manual tuning method requires the staff to enter the antenna adjustment room for adjustment. Various ...

In such a circuit with relatively high sensitivity, the signal jitter caused by this bouncing phenomenon will affect the generation of the control signal. As far as the system is concerned, one action of the button can only produce one "press" and one "lift". If the button signal is decomposed without debounce processing, the jitter signal will also generate a "press" or "lift" pulse, resulting in abnormal device action, and because the controlled end wants to restore the original button Signals, the "press" and "lift" signals must appear in pairs. Due to the uncertainty of jitter, it is very likely that only the "press" signal does not have the "lift" signal, causing the controlled end to stop Drive stepper motor action
