Abstract

The invention discloses a device and method for controlling an electronic-controlled engine. The device comprises an IPC (Industrial Personal Computer) with a touch screen, a PLC (Programmable Logic Controller), a gateway, an ECM (electronic control module) of an electronic-controlled engine, a rotating speed sensor, an oil atomizer and an oil pressure control valve, wherein the gateway integrates a ProfiBus system and a CAN bus system into a whole, so as to enable the IPC attached to the ProfiBus system to send command values of rotating speed, torque and accelerator opening degree to the ECM attached to the CAN bus system, and then the ECM controls an engine to operate; meanwhile, the ECM can send the actual values of the rotating speed, the torque and the accelerator opening degree of the engine to the IPC, so as to realize the monitoring and control for the electronic-controlled engine; the PLC places parameters read from the IPC into an output cache module inside the PLC; the ProfiBus-J1939 gateway reads parameters from the output cache module of the PLC and sends the parameters to the ECM of the engine through the CAN bus; the ECM obtains the engine command value parameters to control the operation of the engine.

Description

technical field [0001] The invention relates to a device and method for controlling an electronically controlled engine, in particular to programmable logic controller (PLC) technology, electronically controlled engine control technology and field bus technology, belonging to the technical field of electronically controlled engine and electrical control technology, applicable to The electronically controlled engine is a construction machinery and test equipment with adjustable power and working conditions. Background technique [0002] Some non-vehicle engines do not directly use the accelerator pedal to control the speed and torque of the engine, but directly send the speed, torque or accelerator opening to the electronic control module ECM of the electronically controlled engine through the J1939 message to control the operation of the engine. Before leaving the factory, the engine must pass the test on the engine bench before it can be sent to the customer. A common engi...
