Embodiment
Diesel locomotive fault self-diagnosis system is further described below in conjunction with the accompanying drawings.
This diesel locomotive fault self-diagnosis system, locomotive microcomputer passes through On-off signal port processing locomotive failure information
Afterwards, locomotive failure information is analyzed and classified, carried fault message and operation finally by CAN communication or RS485 communications
Show and be sent to display screen.
Described display screen is the display screen with touch screen functionality developed based on Linux platform.
Described display screen is provided with malfunction coefficient area, and driver and conductor can click on malfunction coefficient area by touch screen, into failure
Details interface understands more multiple faults situation, and the operation indicating operation shown according to display screen excludes locomotive failure.
Fault message memory module is provided with inside described display screen.
Described On-off signal port number is at least 1.
Described locomotive failure information classification includes starting block failure, traction block failure and conventional fault.
Described startup block failure is including master keys are not closed, storage battery is forced down, battery is grounded, emergency shutdown
Button is pressed, fire alarm.
Described traction block failure includes the berth low not alleviated, train tube pressure of braking, auxiliary power generation failure, excitation control
Device failure processed, urgent excision cock do not reset, main hair contactor failure.
Described conventional fault includes the main hair system failure, the auxiliary hair system failure, diesel engine system failure.
There is this diesel locomotive fault self-diagnosis system fault information acquisition, failed storage, failure modes and operation to carry
The function such as show, specific embodiment is as follows：
1. fault information acquisition and transmission：There is locomotive microcomputer enough On-off signal ports to be adopted as fault message
Collection, is analyzed and is classified according to specific failure situation, is sent to fault message eventually through CAN communication or RS485 communications
Display screen, concrete form are as shown in figure 1, diesel locomotive fault self-diagnosis system detection failure and the flow such as Fig. 8 shown automatically
It is shown.The actual conditions that 1~failure of failure 10 in Fig. 1 can be inputted according to hardware switch amount be designed, if having enough hard
Part interface, number of faults can be changed arbitrarily, for example, can be set to 1~failure of failure 100, simultaneous faults species, failure specific name
Can arbitrarily it design.
2. display screen：Employ in the display screen with touch screen functionality developed based on Linux platform, display screen main interface
