Remote control step motor to solve the problem
Stepping motor controller is itself part of the first to choose to suit your driving mode of motor current and driver chips, such as common motor phase two to four lines, 2 6 line, line 4 phase 5, 3 phase 3 wire, three phase four wire, 5 phase 6 line and so on. And only stepping clock driver chip input signal is, direction, can make three signals, in this way, the remote control also does not want to use the three signals to control. Remote if it is, however, cable, reliability can also, if the wireless control, reliability is poor, so the problems involving whether there is a strict localization requirements, if any, closed loop control, have to do that is to say, spinning the motor side must have the rotary encoder is used to ensure no step, implements the rotation of the specified Angle.
Because the wireless channel is generally one-way, so is unlikely to send back, the closed-loop signals, and so on the sending end should be sent with a validation data, and should contain location information, every time a similar air conditioning remote control to send data, that is to say every time send is not a "forward five pulse" or "upside-down 30 pulse" such a simple message, which should be "to 30 degrees position" or "moved to the zero point on the location of the 1434 steps" this information, so, send to the servo controller, this way according to position myself just now produce the direction and the corresponding pulse signal, and according to the need to open and close the drive in order to realize locking. Radio interference problem by checking to avoid bad reception by absolute location information to guarantee, so, if a signal is not received, signal will come back again next time, you can put the location of the missing up just now, always know that as long as the received signal, can always move to the position you want. Of course, if two-way communication is ideal, remote servers can provide corrective information to the control sender to prevent dislocation.
Learn to thinking about the design, first to consider how to control, remote control motor to control the motor running with signal wire or wireless, single chip microcomputer to control motor, is this a few things
First of all, to use keil to microcontroller programming, stepper motor after their chosen model, connected to the drive, the connection to see drive specifications, major difficult in programming, to define p0, p1, p2 or other mouth as pulse and direction control. As for programs, the key to being able to understand is to be able to debug.
First of all, to use keil to microcontroller programming, stepper motor after their chosen model, connected to the drive, the connection to see drive specifications, major difficult in programming, define your own p0, p1, p2 or other mouth as pulse and direction control. The step motor is an open loop controlling element which converts the electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.
