The network control system of the heavy section car comprises a central processor with a CAN communication module, a LCD, a bus line driver, a power module and a CAN bus line connected with the bus line driver; and the CAN bus line is connected with a plurality of node controllers with CAN communication modules, and the node controllers are respectively connected with sensors of nodes like a diesel oil engine, a traction generator, an electric appliance cabinet, a traction motor, a reduction gear case, an air brake system and the like. The CAN bus line is employed to form network control devices of the heavy section car, so electric system of the heavy section car is simplified, wiring is minimized, cost is reduced and volume is reduced, transmitted information amount of the system is big, and the system is high in practicality and can be widely applied in the heavy section cars.
Description
Technical field
The utility model relates to heavy section car, is specially a kind of network control system of heavy section car.
Background technology
electric driven heavy rail car is a kind of equipment that railway interests's construction and the marshalling of traction large-scale maintenance machinery need, development along with power electronics and computer networking technology, electronic control system and communication system are more and more, as diesel motor, pulling electric generator, Electric Appliance Cabinet, traction motor, reduction gear box, Pneumatic brake systems etc., between these systems, between the Displaying Meter of system and railcar, all need to carry out exchanges data between system and railcar fault diagnosis system, so googol is according to exchange capacity, can not meet the demand of high-speed electric railway as the method that still adopts conventional data exchange, such as, higher reliability, the rapidity of car load information feedback, diversity etc.
Summary of the invention
The utility model can not meet the problem of high-speed electric railway demand for the method for interchanging data that solves existing heavy section car, a kind of network control system of heavy section car is provided.
The utility model is to adopt following technical scheme to realize: the network control system of heavy section car comprises the central controller with the CAN communication module, the CAN bus that is connected with the signal output part of central controller and is located at the liquid crystal display in cab, the bus driver that is connected with the signal end of central controller, power module and is connected with bus driver; Be connected with the Node Controller with the CAN communication module that several are connected with the sensor of the nodes such as diesel motor, pulling electric generator, Electric Appliance Cabinet, traction motor, reduction gear box, Pneumatic brake systems respectively on the CAN bus; Central controller receives or transmitted signal to each Node Controller through bus driver, and the signal that receives is sent to liquid crystal display demonstration each parameters of operating part of car load and fault alarm is provided; Power module is for the central controller of CAN communication module, provide working power with Node Controller, the bus driver of CAN communication module.Described central controller with the CAN communication module, can directly buy from market with the Node Controller of CAN communication module.
During work, power module is the working power that package unit (central controller, bus driver and each Node Controller etc.) provides voltage constant, stablizes and can guarantee the package unit reliability service; Central controller with the CAN communication module is the core of car load control device, the realization of the storage of the program of being responsible for, acquisition and processing, logical operation and the control of data etc., it has the function of gateway, receives or to each Node Controller transmitted signal, and sends LCDs to; Bus driver is the interface between central controller and CAN bus, and the differential sending and receiving function to the CAN bus can be provided, and has anti-interference, the effect of protection CAN bus ability, also increase simultaneously the driving force of signal, namely increase the transmission range of signal, accelerate its transfer rate; Node Controller with the CAN communication module is simulating signal, numerical information or the switching signal that receives the sensor output of the main node such as diesel motor, pulling electric generator, Electric Appliance Cabinet, traction motor, reduction gear box, Pneumatic brake systems on railcar, through the CAN communication module process be converted to can communication on the CAN bus the data message form, and send on the CAN bus by the CAN communication module, will convert to from the data message that the CAN bus receives simultaneously can actuate actuators or simulating signal or the digital signal of illuminating lamp; Liquid crystal display is located in cab, have the functions such as storage, readjustment diagnostic trouble code, fault diagnosis, demonstration car load each several part parameter, warning, facilitate the driver to monitor car load each several part state, can show more quantity of information, more be conducive to the centralized management of information, and facilitate driver or maintenance personal to carry out fault diagnosis, save servicing time.
The utility model adopts CAN (Controller Area Network) controller local area network building network, it belongs to the category of fieldbus, have advantages of very high internet security, communication reliability and real-time, be specially adapted to the industrial environment that environment temperature is abominable and vibration is large; It only replaces the wiring of various signals on railcar with 2 succinct cables, various electronic installations are suspended on these 2 cables by the Node Controller of that module of communicating by letter with CAN, utilize cable to carry out data communication and data sharing between equipment, thereby greatly reduced the wire harness on the car.In addition, because the CAN bus system when expanding, can directly new node be hung on bus, thereby cabling is few, system expands easily, and remodeling flexibly; Each control module can be shared all information and resources by the CAN bus, reach simplification, reduce wiring, reduce number of sensors, avoid controlling the purpose that function repeated, improved system reliability and maintainability, reduces costs, and increased the extensibility of railcar electrical system, obviously improved the overall performance of railcar.
The utility model adopts the CAN bus to set up the network control unit of heavy section car, with the status monitoring, warning, storage and the fault diagnosis that realize the car load all parts and inquiry etc.; Window so that liquid crystal display exchanges with the driver as heavy section car shows each parameters of operating part of car load (as electrical quantity, engine parameter, the speed of a motor vehicle etc.) and fault alarm is provided; The electrical system of heavy section car is simplified, the minimizing of connecting up, transmit contain much information, cost, volume reduce, practical, the method for interchanging data that has solved existing heavy section car can not meet the problem of high-speed electric railway demand, can be widely used in heavy section car.
