Embodiment 1

[0023] figure 1 It is a flow chart of an engine switch automatic control method provided in Embodiment 1 of the present invention. In this embodiment, the switch includes a T15 switch and a main power switch, and the T15 switch is used to provide an enabling signal to the engine controller. This embodiment can It is suitable for the application scenario of controlling the automatic on-off of the T15 switch and completely monitoring the power-off state of the T15 switch during the test run. This method can be executed by a switch control device equipped with a specific functional module. Communicate through the CAN bus.

[0024] Such as figure 1 As shown, the control method includes the following steps:

[0025] Step S1: Obtain the T15 switch message data sent by the host computer.

[0026] Optionally, the CAN communication between the host computer and the switch control device can be realized through a dual-channel CAN bus adapter. The dual channels include a first communi...

Embodiment 2

[0066] Embodiment 2 of the present invention provides an engine switch automatic control system. In this embodiment, the engine switch includes a T15 switch and a main power switch. The T15 switch is used to provide an enabling signal to the engine controller, and the main power switch is used to control the engine The main power supply is powered on or off.

[0067] The engine switch automatic control system provided in the embodiments of the present invention can execute the engine switch automatic control method provided in any embodiment of the present invention, and has corresponding functional modules and beneficial effects for executing the method.

[0068] Figure 4 It is a structural schematic diagram of an engine switch automatic control system provided by Embodiment 2 of the present invention.

[0069] Such as Figure 4 As shown, the engine switch automatic control system 00 includes: a host computer 10, a switch control device 20 and an engine controller 30, and ...

Embodiment 3

[0079] Figure 5 It is a schematic structural diagram of an engine test equipment provided in Embodiment 3 of the present invention.

[0080] Such as Figure 5 As shown, the engine test equipment 100 includes the above-mentioned engine switch automatic control system 00 .

[0081] The engine test run equipment provided by the embodiment of the present invention is provided with an automatic engine switch control system, which is used to implement an automatic engine switch control method. The data is transmitted to the switch control device, so that the switch control device controls the T15 switch to connect or disconnect according to the T15 switch message data; after the T15 switch is disconnected, the second communication channel is used to obtain the state detection data of the T15 switch, and the state detection The data is transmitted to the host computer, so that the host computer can judge whether the T15 switch is completely powered off according to the status dete...

Abstract

The invention discloses an engine switch automatic control method and system and engine test run equipment. The method comprises the following steps: acquiring T15 switch message data sent by an upper computer; transmitting the T15 switch message data to a switch control device through a first communication channel, so as to enable the switch control device to control the T15 switch to be connected or disconnected according to the T15 switch message data; and acquiring state detection data of the T15 switch by using a second communication channel, and transmitting the state detection data to an upper computer, so as to enable the upper computer to judge whether the T15 switch is completely powered off according to the state detection data. The upper computer and the switch control device are provided with two channels, the on-off state of the T15 is monitored while the on-off automatic control of the T15 is realized, the influence of the abnormal power failure of the T15 on the controller is eliminated, the potential safety hazard is reduced, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of engine control, in particular to an engine switch automatic control method, system and engine test equipment. Background technique [0002] After the production of the engine comes off the assembly line, it is necessary to conduct an engine test run, optimize the matching of engine components, and evaluate and verify the performance of the whole machine. [0003] In the prior art, T15 is the enabling signal for controlling the work of the engine controller ECU. When the engine is off-line and the test run is powered off, T15 needs to be powered off first, and then the main power supply of the test run is cut off. The power-off operation is done manually. The problem is that it takes a certain amount of time to cut off the power supply of T15. If the operator cuts off the main power supply at an improper time, it is impossible to ensure that the ignition switch T15 is completely powered off, which will eas...
