Communication control system

Abstract

A communication control system comprises a main controller, a microprocessor, a signal line and an execution component, the microprocessor comprises a communication module and a control module, the main controller is connected with the communication module of the microprocessor through the signal line, and the control module of the microprocessor is connected with the execution component. The maincontroller sends out a control signal, the control signal is transmitted to the communication module through a signal line, the control signal is collected through the communication module and the control module, and the control signal is sent to the motor through the control module and the control module. The control module collects feedback signals at certain time intervals, the feedback signals pass through the control module and the communication module and are transmitted to the signal line, the main controller collects the feedback signals, and the main controller sends out corresponding control signals according to the feedback signals; in this way, the system reduces interface ends and is simpler in structure.

Description

[0001] This application is a divisional application for the patent application with application number 201611009708.9. 【Technical field】 [0002] The present invention relates to a communication system, in particular to a communication control system. 【Background technique】 [0003] At present, the electric pump is mainly used in the refrigeration cycle of the vehicle. The operation of the electric pump is realized by the control system of the electric pump. The electric pump includes a motor and a rotor. The motor drives the rotor to rotate, and the motor control system controls the rotation of the motor; the control system of the electric pump includes Main controller, microcontroller and communication control. The main controller sends control commands to the microprocessor through the communication system. The microprocessor analyzes the control commands and controls the motor rotation. At the same time, the microprocessor feeds back the operating status of the electric p...

Problems solved by technology

[0004] Usually, the main controller is the controller of the vehicle, and the microprocessor is integrated on the electric control board of the electric pump. The control information and feedback information are transmitted between the main controller and the microprocessor through the communication system. A communication protocol is formed between microprocessors. In order to prevent signal interference, control information and feedback information are usually transmitted through a signal line, which makes the connection of the control system relatively complicated.
