Research Of The Wireless Transmission System For Locomotive Drives Information

Develop locomotive drive a vehicle information datum wireless purposeof transmission system Train operate, control all-round popularization andsome locomotive safe operation to record device assist input to measure thecontrol device use, base on information and win greater development. Atpresent, though some have locomotive realize some operation information andonline dynamic detection of status information, control and diagnose thathandle the function, but information that apparatus record the to finishmessage turn and store by transferring to and storing the apparatus in holdingtype when the locomotive puts in storage basically. Except car informationtransfer to, store download year, run,, when locomotive trouble or unexpectedsituation takes place in train, car-mounted information to engineeringdepartment, drive a vehicle deployment department ,etc. know situation to bevery much important even dynamically, so, set up the locomotive --Datacommunication system among ground , ground long-range to follow , inquiresystem to raise engineering management , traffic safety and technicalequipment and railway informationization very much important.Development of " locomotive drive a vehicle information data wirelesstransmission system " rely on existing LKJ2000 type control the device,locomotives safety equipment such as TAX2 comprehensive monitoringdevice , locomotive computer ,etc., and ground computer , server system,utilize the modern wireless and wired communication means to set up the car --Data wireless communication system of ground, can realize train real-timeGPRS of information transmit with a large number of record file wirelessnetwork at a high speed download put in storage , in real time, person whorealize transfer department know train in transit security warning informationoperate , at any time, and meet an urgent need to converse etc. to real-timeinquiry to run the status information. Locomotive drive a vehicle information data radio transmitting deviceconvey to train of ground operate real-time state message may be regardedDMIS as wirelessly, the information in completed projects such as TMIS, CTC,etc. is supplemented, offer the information when the ones that operate arecontinuous and real on the way of train for system described above, can graspthe operation conditions of the train in time, correctly.Feasible function of wireless transmission system of information that thelocomotive drives a vehicle Locomotive drive a vehicle information wirelesstransmission system by some year such as car, and department of ground,make up. Realize the collection of car-mounted information and sendcar-mountedly partly. The earth's surface part realizes that receives deals withand distributes bike control and data of the apparatus in year. Pass year such ascar, ground system set up locomotive connect with wireless communicationbetween ground;Utilize the wireless LAN of high speed to solve thetransmission of a large amount of non-real-time information, utilize GSM/GPRS (reserve GSM-R interface) transmission solving brief, real-timeinformation. To contain Model JK00430 locomotive walk locomotive ofmonitoring device, department of conduct, can leave locomotive the conduct akey part (like the case bearing of the axle, electrical machinery bearing, andwheel is to lasting surfacing at gear wheel at axle bearing, transmissionnewspaper) transmit to ground when the line monitors and diagnoses that realwith the early warning information of trouble, realize trouble informationground management and trend analysis of a key part of conduct, go in thelocomotive .The main function of the system includes: Inquiry of the real-timeinformation of operation conditions of train;The personnel on duty of groundconverse with the emergency of the locomotive driver;The dispatcher ordersto upload;The whole data rotate wirelessly and store;The status informationof the locomotive and fault alarm information are transmitted long-rangly inreal time. Second, the car-mounted host computer hardware forms Thehardware of the car-mounted host computer is mainly made up of major partof following eight: Power board, PC104 CPU card, baseplate, PCMICAadapter, LED display board, wireless office land network card, GSM/ GPRSpackage board, aerial and feeder system. PCMCIA adapter change each otherPC104 bus and PCMCIA bus;GPRS package board one bunch of mouths andCPU main board communication through RS232, realize the long-rangetransmission of the data;LED display board realizes the informationinstruction;The WLAN net card realizes the high-speed download of a largenumber of data under the control of CPU;Base plate integrated PC104 bus andcommunication to the outside control the interface, the interface of the audiofrequency. Third, connection of the car-mounted apparatus of the wirelesstransmission system After the car-mounted host computer installs and takesone's place, need joining with various control checkout equipment on thelocomotive, including: WLAN large line, GSM/ GPRS are wireless andcontrolling device, TAX2 device, car-mounted computer checkout equipment.Fourth, application prospect of the wireless transmission system ofinformation that the locomotive drives system in engineering after departmentadopt in a large amount, can fit controlling after putting in storage, walkmonitoring device, locomotive signal recording instrument, department ofconduct, locomotive operating mode recording instrument. Whole data filethat record transfer through wireless LAN to, store data of getting of the server,all relevant business segments can transfer and analyze and process with thedata in the server of the data. Locomotive can control while operating, theconduct department monitors or axle temperature calls the police to leave,shake car appearance, computer cupboard, DC 600V supply power locomotivethat device measure operate status information send ground to in real time soas to fixed time interval, touch off by incident way send all device of warningmessages to the ground in real time. For realize, monitor safely to in transitoperation of locomotive, preparing offer datum support, thus improveengineering management and engineering level. The ground computer system,through transmitting the analyzing and processing of information to thewireless, can grasp the locomotive trends at any time, including thelocomotive lives in the kilometer to mark, the present operating mode of thelocomotive, train brakes state, can realize the electronic map of the locomotive,functions such as the stock movement in and out of the warehouse dynamicmanagement of the locomotive.
