Embodiment 1

[0039] In this embodiment, according to the idea of ​​modularization, the functional modules of the control circuit are sorted out, such as figure 2 , which includes:

[0040] (1) The communication module completes the digital communication function between the upper computer and the control module. This module includes a CAN communication module, a 485 serial communication module, and a 232 serial communication module to adapt to different communication requirements from the upper computer;

[0041] (2) The position calculation module converts the motor rotor angle signal into a digital quantity. This module includes a photoelectric encoder position calculation module and a resolver position calculation module to adapt to different motor rotor position feedback forms;

[0042] (3) The I / O isolation module performs electrical isolation and level matching on the digital I / O signals of the input and output control modules;

[0043] (4) The signal conditioning module filters an...

Abstract

The invention belongs to the technical field of circuit design of AC servo drivers in gun servo systems, and particularly relates to a universal control module for a gun AC servo driver. According tofunctions to be realized by a circuit of the control module, a control circuit is divided into an interface module, an I / O isolation module, a power conversion module, a communication module, a position calculation module, an operation and control module, a logic control module and a signal conditioning module according to a universal and modular design method, wherein the communication module comprises a CAN communication module, an RS485 communication module and an RS232 communication module; the position calculation module comprises a rotary transformer position calculation module and a photoelectric encoder position calculation module, then circuit design is conducted on all functional modules of the control circuit, electronic components involved in the circuit are patch products which are small in size and reliable in function, and printed board layout and design are conducted according to a multilayer board design method for minimizing layout, so that a control module product with the size of 130mm*85mm is formed.

Description

technical field [0001] The invention belongs to the technical field of circuit design of an AC servo driver of a artillery servo system, and in particular relates to a general control module of an AC servo driver of a artillery, which is a modular design and general design technology of the control circuit of the AC servo driver. Background technique [0002] In the artillery follow-up system, the AC servo driver controls the high-low AC servo motor and the azimuth AC servo motor to move at a given speed, and controls the movement of the gun barrel in the azimuth and high and low directions. To realize the speed control of the AC servo motor, it is mainly completed by the control circuit and the drive circuit of the AC servo driver. The signal is processed and calculated, and the control signal is output to the drive circuit. The drive circuit controls the on-off of the power tube through isolation and power amplification to achieve the purpose of controlling the current and...
