Description
Technical field
The present invention relates to engineering truck technical field, in particular to the touch-control of a kind of rail engineering automobile based on Codesys is aobvious
The programing system and electric-control system of display screen.
Background technique
Rail engineering automobile is a kind of special railway locomotive, is made of diesel locomotive and construction machinery mounted.According to
Its function, rail engineering automobile, which can be divided into, makes a variety of works such as cleaning vehicle, mobile rail-welding vehicle, rail grinding machine, catenary erection vehicle firm by ramming
Journey vehicle is mainly used for the maintenance maintenance work of the material transportation, all kinds of construction operations and existing line of new route, is railway work
It is engaged in, the important equipment of telecommunication and signaling branch.Rail engineering automobile display screen is used to show that the locomotive equipment of rail engineering automobile (such as to start
Machine, gearbox etc.) and operating equipment (such as crane, track grinding head etc.) running state information, cooperation key etc. inputs dress
It sets and completes interactive operation.Since different types of rail engineering automobile exists significantly in dynamical system, the engineering machinery of carrying
The interactive function of difference, the content and realization that need to show is also far from each other.Since display screen supplier is to the work of rail engineering automobile
Industry process, key control point is simultaneously indefinite, therefore according to the tool of rail engineering automobile after rail engineering automobile main engine plants common procurement display screen
Body function demand, increase display is voluntarily write after corresponding data collecting card, key panel, the embedded program of control is realized
With the interactive function of railcar, Operation Van.
Referring to FIG. 1, its structural schematic diagram for the electric-control system of existing rail engineering automobile.The rail engineering automobile electricity
Control system includes the mobile unit developed based on embedded program, such as vehicle-carrying display screen, data collecting card and key face
Plate, and locomotive equipment, such as Engine ECU, gearbox ECU etc. based on PLC program exploitation.But existing track engineering
Vehicle electric-control system exposes following three points defect in practical applications:
1) hardware spending is big.Due on rail engineering automobile carry there are many, many types of engineering machinery, need show and interaction
Information is unable to satisfy far more than passenger and freight train, common vehicle-carrying display screen interface quantity and type, therefore need to be according to the type rail
The demand for control of road engineering truck, additionally installs the input-output equipment such as a certain number of data collecting cards, key panel additional, hardware at
This increase, reliability reduce.
2) software development structure of electric-control system is unreasonable.Since the locomotive equipment on rail engineering automobile mostly uses greatly PLC
As controller, programming language are as follows: ladder diagram, the PLC languages such as ST structured text, and the common car-mounted display of outsourcing
Screen, data collecting card, key panel common development language be C, C#, C++ etc., do not support PLC language, cause the electricity of main engine plants
Vehicle-carrying display screen cannot be added directly into the PLC engineering of electric-control system by control system developer as an equipment to be compiled
Journey.Existing system software development process generally divides three steps, and the PLC of most of mobile unit is first completed using PLC language
Program development is controlled, the control program development that embedded programming language completes vehicle-carrying display screen is reused, finally combines the two
Debugging.Under above-mentioned development structure, system software framework is excessively complicated, and exploitation, test and version management difficulty are higher.
3) vehicle-carrying display screen program development difficulty is big.PLC language is the main of rail engineering automobile electric-control system developer
It is obvious with embedded development language difference to develop environment etc. in grammer, rule for working language, PLC language.Due to common
Vehicle-carrying display screen cannot support PLC language to develop, when the developer of the electric-control system of main engine plants being caused to have to spend a large amount of
Between be familiar with purchased vehicle-carrying display screen specify embedded development language and environment after could develop corresponding display, interactive program,
Exploitation, debug time are long, and program reliability is low.
For defect existing for rail engineering automobile electric-control system in the prior art, those skilled in the art always search for solving
Method certainly.
