Problems solved by technology

[0002] The system test of the diesel engine electronic control system software is a complex and time-consuming work, which is mainly based on manual testing, which consumes a lot of time in repeated physical operations, and the results of each test case are judged by humans, making different The test results obtained by the testers are very different, the repeatability of the test is poor, and the test efficiency is low
At present, although there are a variety of execution software for automated test cases on the market, the diesel engine electronic control system software is a strong real-time control software, and real-time simulation testing methods need to be applied during testing. In order to realize the functions of automatic loading, configuration and operation of different diesel engine operating conditions, there is currently no special device at home and abroad that can directly perform automatic testing of diesel engine electronic control system software

Abstract

The invention provides a device and a method for automatically testing electronic control system software of a diesel engine and belongs to the technical field of diesel engine test. The device for automatically testing the electronic control system software of the diesel engine comprises a controller, a simulating hardware platform and a software platform, wherein the simulating hardware platform is connected with the controller; the software platform comprises modeling simulating software, test management software and automatic testing case executing software; the controller, the simulating hardware platform and a diesel engine model form a closed-loop system. The device and the method have the beneficial effects that hardware, a model and test environment for running the electronic control system software are fused with each other, the automatic test for the whole working condition of the running of the engine is completed, the test reliability is increased and the working strength and test time of a worker can be reduced.

Description

technical field [0001] The invention belongs to the technical field of diesel engine testing, and in particular relates to a diesel engine electric control system software automatic testing device and method. Background technique [0002] The system test of the diesel engine electronic control system software is a complex and time-consuming work, which is mainly based on manual testing, which consumes a lot of time in repeated physical operations, and the results of each test case are judged by humans, making different The test results obtained by testers vary greatly, the repeatability of the test is poor, and the test efficiency is low. At present, although there are a variety of execution software for automated test cases on the market, the diesel engine electronic control system software is a strong real-time control software, and real-time simulation testing methods need to be applied during testing. Integration can realize functions such as automatic loading, configur...
