Optical engine control method and device

Abstract

The invention discloses an optical engine control method and a device. According to the control method and the device, subsystem data sharing is facilitated, the flexibility is high, the control strategy can be rapidly achieved, the universality is high, and adjustment is easy. Data sharing among different subsystems such as sensors, actuators, combustion analyzers, data acquisition systems, dynamometers and the like which can be used for different interfaces can be slightly modified according to signal characteristics, and results are convenient to store, analyze, display and process. Due tothe fact that the high-performance single-chip microcomputer is adopted, complex real-time signals can be processed conveniently, and when EGR and VVT control is needed, a control strategy algorithm can be achieved conveniently through model modification.

Description

technical field [0001] The invention relates to the technical field of internal combustion optical testing, in particular to an optical engine control method and a device thereof. Background technique [0002] Some schemes of existing electronic controllers for optical engines use domestically purchased software and hardware, and are equipped with dedicated host computer acquisition, test, and calibration software. This method can carry out tests well, but the disadvantage is versatility and flexibility Not enough, when it is necessary to change the interface and software, it cannot be done, or it needs to be realized through foreign suppliers. Some solutions use 16-bit single-chip microcomputer or 32-bit single-chip microcomputer to realize controller development by writing codes. It is difficult to change the control algorithm, and it is more difficult to modify the software part when the calibration scheme changes. More importantly, the data among existing combustion ana...

[0002] Some schemes of existing electronic controllers for optical engines use domestically purchased software and hardware, and are equipped with dedicated host computer acquisition, test, and calibration software. This method can carry out tests well, but the disadvantage is versatility and flexibility Not enough, when it is necessary to change the interface and software, it cannot be done, or it needs to be realized through foreign suppliers

Some solutions use 16-bit single-chip microcomputer or 32-bit single-chip microcomputer to realize controller development by writing codes. It is difficult to change the control algorithm, and it is difficult to modify many software parts when the calibration scheme changes.

More importantly, the data among subsystems such as existing combustion analyzers, data acquisition systems, and dynamometers often cannot be synchronized and shared, which causes waste to the effective use of test data
