Abstract

The utility model provides a positioning and orienting device for a RFID locomotive and relates to the operation safety monitoring equipment of the railway system. The flat shunting lamp display system currently used in the shunting work works based on the visual examination of the driver and shunting personnel and is prone to cause various accidents because of watch errors, and therefore has become a large bottleneck in the safe production of the railway transportation. In the utility model, RFID are embedded underground at each key point of the station and send out wireless radiofrequency signals, which are identified by a RFID identifier arranged on the locomotive; the readout signals are transmitted to a locomotive-borne host computer, which then, through video and audio methods, provides the information on the front situation for the driver. So the utility model can effectively prevent accidents in the shunting work and has advantages of preferable accuracy, high automatization and strong adaptability (adapting to the shunting speed with 0-120km/h and the operating temperature range with minus 20-plus 60 degrees).

Description

RFID locomotive positioning orienting device

Technical field

The utility model relates to the operation safety monitoring apparatus of computing machine integrated control device field, the especially railway system.

Background technology

At present, the accident rate of domestic railway train arrangement operation is high, has become a big bottleneck of restriction railway transportation production safety.Though a lot of marshalling stations and big-and-middle-sized station have used the flat shunting lamp to show system in the shunting service process, but, present flat shunting lamp rely on yard man and driver and conductor to confirm the ground cab signal because showing system, locomotive will lean on driver and yard man's range estimation to determine with respect to the position of each key point in the marshalling process (signal, derailer, soil retaining, track switch), is easy to advance rashly, bump and roll derailer, hit the soil retaining, squeeze accident in shunting operation such as track switch, locomotive conflict by locomotive takes place in lookout signal error or inadvertent.

Summary of the invention

The purpose of this utility model is to avoid existing shunting locomotive to rely on yard man and driver and conductor to confirm the ground cab signal and the job safety hidden danger that exists, and a kind of safe, accurate, reliable, stable shunting locomotive positioning and orienting device is provided.

The utility model has adopted less radio-frequency emission (RFID) technology, when locomotive operation arrives each key point, be embedded in underground RFID and can send wireless signal, vehicle-mounted RFID recognizer read output signal, and be transferred to on-vehicle host, by sound and pictorial information prompting driver the place ahead situation, can help the driver to prevent the shunting service accident effectively.

The technical scheme that realizes above-mentioned purpose is:

RFID locomotive positioning orienting device, form by two parts, a part is the RFID that is embedded in the crucial place, each field, station of locomotive process, another part is a mobile unit, the RFID recognizer is installed on the locomotive, the RFID recognizer is connected with on-vehicle host by RS-232, and on-vehicle host is connected with voice alerting unit with its outdevice driving position telltale, and RFID and RFID recognizer carry out the signal transmission by less radio-frequency.

Principle of work of the present utility model is as follows:

The field device RFID that stands is embedded in each key point (signal lamp of locomotive process, derailer, track switch, the soil retaining) preceding, when locomotive through out-of-date, the recognizer that RFID is installed on the locomotive is read the information of the RFID emission that is installed on the field, station, be transferred to on-vehicle host through the RS-232 serial ports, on-vehicle host is promptly judged the distance of the present residing position of locomotive apart from key point, processing by program, main frame promptly demonstrates the information of locomotive the place ahead key point and the locomotive position apart from key point on the driving position telltale, the orientation of locomotive is to establish two RFID by burying underground along track in a side of each key point, both are at a distance of 1 meter, when locomotive passes through, on-vehicle host just can be determined the direction of locomotive operation by the time sequence of judging two RFID and transmitting, after the on-vehicle host routine processes, on the driving position telltale, show the service direction of locomotive respectively, remind the present service direction of driver's locomotive by voice alerting unit simultaneously.The driver just can observe present position of locomotive and service direction from the driving position telltale, the measure that the situation in the place ahead and driver should take, and the measure that the vehicle-mounted voice Tip element should be taked by voice messaging prompting driver's the present situation and driver, by image and voice suggestion, the driver does not need to observe the accurate information that ground signal just can clearly be recognized locomotive operation the place ahead, this device can be realized safety, accurately, reliably, stable shunting locomotive positioning and directing, the job safety hidden danger of avoiding existing shunting locomotive to rely on yard man and driver and conductor to confirm the ground cab signal and existing can help the driver to prevent the shunting service accident effectively.

The utlity model has the accuracy height, the strong and high characteristics of degree of automation of comformability can adapt to the various speed of a motor vehicle when shunting, can be under-20～+ 60 ℃ weather normal operation, can prevent the job safety hidden danger of confirming that manually ground signal brings conscientiously.
