Driver for radar servo system

Abstract

The invention discloses a driver for a radar servo system. The driver is used for driving a direct current motor or an alternating current motor. The driver comprises a control module, a drive module, a communication module, an analog input / output module, a digital quantity input / output module, a position / speed detection module, a human-machine interface module, a power module, a current detection module and a detection and protection module. The control module is connected with the parts of the driver and used for conducting coordination control over the parts of the driver so as to drive the motor. The drive module is used for driving and controlling the motor. The communication module is used for controlling communication between the driver and the motor. The position / speed detection module is used for detecting the position and the speed of the motor. The current detection module is used for detecting the magnitude of two-phase currents output by the drive module, converting the two-phase currents into voltage signals and then transmitting the voltage signals to the control module for current loop closed-loop control. The detection and protection module is used for monitoring currents and voltages of the driver.

Description

technical field [0001] The invention relates to a driver, in particular to a driver used in a radar servo system. Background technique [0002] The traditional radar servo system generally adopts the control mode of industrial driver + PLC (Programmable Logic Controller, PLC), the commercial driver is responsible for the drive of the servo system, and the PLC is responsible for the control of the servo system. Because radar generally works in the wild environment, ordinary industrial drives and PLCs cannot withstand harsh environments such as high-intensity vibration, rain, fog, and high temperature. In addition, high-performance industrial drives and PLCs are expensive, which will lead to an increase in the cost of the entire radar. For radar servo systems, different application requirements require different types of motors. For example, some applications require DC motors, and some applications require AC motors. Different types of motors need to be equipped with differe...

For radar servo systems, different application requirements require different types of motors. For example, some applications require DC motors, and some applications require AC motors. Different types of motors need to be equipped with different types of drivers, which makes the drivers lack universal sex
