Actuator controller based on communication bus and control method

Abstract

Provided are an actuator controller based on a communication bus and a control method. The actuator controller comprises a main control module, a display and operation module, and an AC / DC power supply module. The output ends of the AC / DC power supply module are respectively connected with the main control module and the display and operation module. The main control module is connected with the display and operation module. The main control module is further connected with a controlled system and a measurement and control system. According to the invention, a bus module and a bus processing circuit are arranged, and the adoption of the bus mode is conducive to signal sharing, lower circuit complexity and higher reliability. As a drive and diagnosis circuit is arranged, the need for fault detection under the condition of frequent plug and pull can be satisfied, and quick locating and fault solving are facilitated. Through actuator controller strategy optimization, function expansion can be realized, and the difficulty in secondary development of the measurement and control system can be reduced. The control method of the invention is simple, and easy to operate and implement.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to an actuator controller and a control method based on a communication bus. Background technique [0002] With the improvement of the electronic degree of automobiles, electronic control technology is more widely used in vehicles (such as transmissions, retarders, etc.) to meet the needs of reducing driving intensity and improving vehicle safety. [0003] For products that rely on the action of electronically controlled actuators (control valves) to achieve testing, a set of dedicated controllers must be designed to achieve product testing. If the traditional method is installed, the technical solution adopted is the mode of electrical control (relay, switch). This scheme has the following disadvantages: [0004] Logic control, component diagnosis, remote and joint control are not easy to realize, the wiring is complicated, and the cost of components is high...
