Abstract

The invention discloses a system and method for implementing speed control of a diesel engine on the basis of multiple CAN communication protocols. A device comprises a bus interface unit, a CAN protocol analysis unit and a CAN communication unit, wherein the CAN protocol analysis unit comprises a plurality of protocol modules corresponding to a plurality of CAN communication protocols; the CAN communication unit is used for executing communication based on the CAN communication protocols; one end of the CAN protocol analysis unit is connected with an engine master control system through the bus interface unit; the other end of the CAN protocol analysis unit is connected with an electronic injection control system of the diesel engine through the CAN communication unit; and the CAN protocol analysis unit calls the protocol modules to analyze communication data between the engine master control system and the electronic injection control system of the diesel engine so as to execute CAN communication in required types. The method is used for implementing speed control of the diesel engine by controlling the system for implementing speed control of the diesel engine. The system and method for implementing speed control of the diesel engine on the basis of the multiple CAN communication protocols have the advantages of simple structure, low required cost, capability of implementing speed control of the diesel engine on the basis of the multiple CAN communication protocols and high control efficiency.

Description

technical field [0001] The invention relates to the technical field of diesel engine control, in particular to a system and method for realizing diesel engine speed regulation control based on multiple CAN communication protocols. Background technique [0002] The traditional diesel engine stepper motor speed control system such as figure 1 As shown, specifically, by driving the stepper motor installed on the diesel engine to control the combined regulator of the diesel engine, the function of adjusting the speed of the diesel engine is realized. The stepper motor speed control system is not suitable for electronically controlled diesel engines, so it has gradually been controlled by EFI technology substitution. In the EFI control technology of the diesel engine, the EFI controller exchanges data with other components such as the locomotive control system in the diesel locomotive based on the CAN (ControllerAreaNetwork, controller local area network) communication protocol ...

AI Technical Summary

Problems solved by technology

However, the CAN communication network is an internal network, and the CAN communication protocols adopted by different diesel engines may be inconsistent. Therefore, the above-mentioned diesel engine speed control system based on EFI control cannot be connected to diesel engines with various internation
