Control device for engine cold start test development

Abstract

The present invention discloses a control device for engine cold start test development. The control device comprises a PLC (Programmable Logic Controller), intermediate relays and control buttons; the PLC is used for data processing and sequential control; the input ends of the intermediate relays are connected with the PLC; the output ends of the intermediate relays are connected with a test bench system; the intermediate relays comprise a first intermediate relay and a second intermediate relay, wherein the first intermediate relay is used for controlling the power source of a starter, and the second intermediate relay is used for controlling an ignition switch; and the control buttons comprise a start button and a stop button which are used for realizing the start and stop of the test bench system. According to the control device, the PLC is adopted to perform control, program optimization is performed according to test requirements, so that wiring is not required to be adopted; the program of the PLC has high reliability, is stable and controllable; and an integrated structure is adopted, and therefore, the control device is small in size and convenient to move.

Description

technical field [0001] The invention relates to the field of engine cold start tests, in particular to a control device for the development of engine cold start tests. Background technique [0002] The target temperature of the low-temperature reliability test of the engine starter on the cold start bench of the test center is -25°C. To carry out the reliability test of the starter, it is necessary to make an automatic control device to realize the conversion of different working conditions and meet the control requirements of 60S for each cycle and 1000 cycles respectively. [0003] At present, there is a lack of a control system for controlling the starter at low temperature and cold start of the engine, which makes it impossible to carry out the test. [0004] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion...
