The utility model has the benefit that the on-line fault diagnosis device can quickly check locomotive faults, is of great significance in locomotive operation and maintenance, and can intelligently judge the fault positions, reduce the incidence of faults and damage and achieve real-time monitoring.
Description
Technical field
The utility model belongs to the technical field of railway locomotive, is specifically related to a kind of railway locomotive fault on-line diagnostic device.
Background technology
The problem and the shortcoming of existing railway locomotive failure judgment device:
1, indeterminate for the judgement of locomotive failure place, can not instruct the driver and conductor to judge locomotive failure rapidly accurately in actual applications.
Even 2, locomotive failure is judged in existing design, can not in time pass through the original performance of device self-recovery locomotive, do not possess intelligent characteristics.
3, the fault display interface is not directly perceived, can not provide clear and definite failure message and treatment measures to the driver and conductor.
4, existing apparatus extracts failure message by a large amount of sensors, and locomotive provides a large amount of wirings for diagnostic device, makes troubles to locomotive inspection and repair.
Summary of the invention
The utility model is in order to solve the problems referred to above that the railway locomotive failure judgment device exists.
The utility model adopts following technical scheme:
A kind of railway locomotive fault on-line diagnostic device, comprise analog input module, digital input module, control treatment module, digital output module, display and microcomputer, the input end of described control treatment module connects the output terminal of digital input module, analog input module and locomotive LCU, DCU, the input end of control treatment module is connected by the CAN bus with the output terminal of locomotive LCU, DCU, the signal transmission ends of control treatment module is connected with display with microcomputer respectively by the RS485 bus, and the output terminal of control treatment module is connected with digital output module.
The utlity model has following beneficial effect:
1, locomotive failure can be investigated rapidly, for locomotive operation, maintenance very big directive significance is arranged.Describe the locomotive failure position in detail by literal and locomotive picture, and locomotive picture is the true picture of locomotive that failed equipment is installed, very strong specific aim arranged for quick eliminating locomotive failure.Existing pick-up unit can't realize that this installs this characteristics.
2, because the data message storehouse of diagnostic device is arranged, device can intelligence the failure judgement place, and can carry out redundancy backup for crucial locomotive control circuit, as the motorcycle pantograph power supply, main outage source is installed by self power supply and is carried out redundancy backup, and the said equipment power fail appears in locomotive, the driver and conductor can enable standby power supply immediately, the event of minimizing machine, the generation that machine is broken; Install main frame simultaneously and adopt the high capacity information memory cell, can to locomotive information carry out with 3 seconds be the storage of one-period, for locomotive operation information provides sufficient gross data, these are the irrealizable functions in present Locomotive Fault Diagnosis unit.
3, network system has increased the partial information of controlling power supply, locomotive brake pipeline when guaranteeing the network communication quantity of information, can realize monitoring in real time.This function is the upgrading to existing equipment, and just be lower than 88V at voltage carries out voice suggestion to existing weaponry and equipment, and this device can be pressed signal by intelligent detection net, points out the driver and conductor to note the running status of locomotive storage batteries constantly.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model
Among the figure: 1-digital input module, 2-analog input module, 3-numeral output module, 4-control treatment module, 5-display, 6-microcomputer, 7-RS485 bus, 8-CAN bus, 9-locomotive LCU, DCU, 10-power supply.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further.
The railway locomotive fault on-line diagnostic device mainly is made up of following components: digital input module, digital output module, analog input module, control treatment module, power supply, display, microcomputer.The input end of control treatment module 4 connects the output terminal of digital input module 1, analog input module 2 and locomotive LCU9, the input end of control treatment module 4 is connected by CAN bus 8 with the output terminal of locomotive LCU, DCU 9, the signal transmission ends of control treatment module 4 is connected with display 5 with microcomputer 6 respectively by RS485 bus 7, and the output terminal of control treatment module 4 is connected with digital output module 3.Analog input module 2 and control treatment module 4 are integrated on the plate, i.e. the slave computer control panel.
The numeral input is the switching value signal of 110V on the locomotive, and analog input is 0 ~ 10V and 4 ~ 20MA signal.Mainly be to detect locomotive LCU, do not detect signal on the equipment such as DCU.Detected signal enters control treatment module and carries out analog to digital conversion or judgement after becoming the manageable signal of control treatment module through processing such as voltage of transformation filtering.The slave computer control panel is on the one hand by RS485 bus and LCU, and the coherent signal status data of locomotive is obtained in communications such as DCU.Receive 86 signals from the LCU device by the RS485 bus.Signal such as locomotive operating mode, each subsidiary engine contactor feedback for example.Receive 12 signals from the DCU device by the RS485 bus.Signals such as locomotive current/voltage, locomotive speed for example.Communicate by letter with display by the RS485 bus on the other hand, receive display order control related device and make control action or send data to display.System judges the locomotive operation situation, and provides driver locomotive failure information and disposal route accurately by the collection and the analysis of a large amount of raw data.Simultaneously critical data is preserved, the cycle is 3 seconds.Data status in the time of can inquiring about locomotive moved at that time when having an accident is for handling and judging that the locomotive accident provides accurate data information.
