Abstract

The invention relates to a heavy type rail car, in particular to a network control system of the heavy type rail car. The network control system of the heavy type rail car solves the problem that data changing method of an existing the heavy type rail car can not meet requirements of a high speed electrified railway. The network control system of the heavy type rail car comprises a central control unit with a controller area network (CAN) communication module, a liquid crystal display, a bus driver, a power source module and a CAN bus connected with the bus driver. A plurality of node controllers with CAN communication modules are connected with the CAN bus. The plurality of node controllers are respectively connected with sensors of nodes such as a crude oil engine, a traction generator, an electrical equipment cabinet, a traction motor, a reduction gear box and an air braking system. The network control system of the heavy type rail car is formed by the CAN bus so that an electrical system of the heavy type rail car is simplified, arrangement of wire is reduced, transmitted information content is large, cost and size are reduced, practicality is good and the network control system can be widely used for heavy type rail cars.

Description

The network control system of heavy section car

Technical field

The present invention relates to heavy section car, be 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, such 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 the railcar fault diagnosis system, so googol is according to exchange capacity, do not satisfied the demand of high-speed electric railway such 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 present invention does not satisfy the problem of high-speed electric railway demand in order to solve the method for interchanging data that has heavy section car now, a kind of network control system of heavy section car is provided.

The present invention adopts 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 links to each other and be located at the liquid crystal display in the cab, the bus driver that links to each other with the signal end of central controller, power module and link to each other with bus driver with the signal output part of central controller; 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 from market, buy 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, to guarantee the reliable and stable operation of package unit; Central controller with the CAN communication module is the core of car load control device, the realization of storage, data acquisition and processing, logical operation and the control of the program of being responsible for 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 the 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 the 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 the cab, have the functions such as storage, readjustment diagnostic trouble code, fault diagnosis, demonstration car load each several part parameter, warning, make things convenient for 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 make things convenient for driver or maintenance personal to carry out fault diagnosis, save servicing time.

The present invention adopts CAN (Controller Area Network) controller local area network building network, it belongs to the category of fieldbus, have very high internet security, communication reliability and real-time advantage, 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 the 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 the 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 the 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, reduction cost, and increased the extensibility of railcar electrical system, obviously improved the overall performance of railcar.

The present invention 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.; With the window that liquid crystal display exchanges with the driver as heavy section car, show each parameters of operating part of car load (such 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 does not satisfy the problem of high-speed electric railway demand, can be widely used in heavy section car.
