Description

Rail car wireless radio frequency positioning control device

technical field

The utility model relates to a wireless radio frequency positioning control device for railcars, in particular to a positioning control device for railcars implemented in large-scale factory areas.

Background technique

The advancement of industrial technology drives economic growth, and as enterprises compete, improving work efficiency is obviously a necessary condition for growth. For steel factories, a large area of land is required for the installation and operation of each factory building in the factory. Because the workshops are far away from each other, in order to transport materials for operation, rails are usually built in each factory room, and rail cars are used to drive on the rails to transport materials or finished products to the location. Wherein the rail car is composed of a locomotive driven by a person and a torpedo car towed for loading molten iron. At the same time, there will be many groups of rail cars passing on the track. Known mode is that dispatcher utilizes radio walkie-talkie to carry out dispatching operation, informs respectively the route that the rail cars of each group will pass. Although this has achieved the purpose of assigning work, the dispatching personnel cannot know the location and speed of each group of railcars at any time, and can only know the approximate location through radio communication with each other, and cannot achieve accurate control of the track. The purpose of vehicle traffic, and accidents may occur if you are not careful, resulting in personal injury and vehicle damage. In addition, although some operators try to use satellite positioning (GPS) to control the positioning. However, a separate satellite positioning system will cause unclear vehicle positioning for switch points or parallel tracks, and the complex communication environment in the factory building and station will cause a lot of interference, which will also cause the situation that the satellite signal cannot be received or the signal is poor, so it cannot be confirmed. There is a need to improve the lack of improvement.

Utility model content

The technical problem to be solved by the utility model is to provide a wireless radio frequency positioning control device for rail cars in view of the difficulty in controlling the rail cars in the known large factory area, resulting in poor work efficiency and even the absence of accidents. The location and the speed of the vehicle can achieve the purpose of really controlling the passage of the rail car.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a radio frequency positioning control device for railcars, which is mainly provided with more than one radio frequency identification chip within a set distance of each section on the track, and by The locomotive and the torpedo car are composed of a railcar, and the locomotive and the torpedo car are equipped with a card reader and a radio modem, so that when the railcar passes the radio frequency identification chip on the track, the radio frequency identification chip can be read by the card reader , and use a radio modem to transmit it to the receiver in the monitoring center and display it on the screen.

Compared with the prior art, the utility model has the beneficial effect that: by means of the utility model, when the rail car passes by, the card reader (RFID Reader+RFID Antenna) can be used to read the radio frequency identification chip (RFID Tag) at the track , and use the radio modem (RADIO MODEM) to transmit it to the screen in the monitoring center to display its position and speed, so as to achieve the purpose of controlling and improving work efficiency. Different from common RFID applications, this device installs the radio frequency identification chip (RFID Tag) at a fixed point, and installs the card reader (RFID Reader+RFID Antenna) on the moving locomotive and torpedo car. The installation method will greatly reduce the installation cost, and it is estimated that the difference between the two can reach 45 times.

Detailed ways

In order to make it easier for your review committee to understand the device of the present invention and the effects it can achieve, it is described as follows in conjunction with the drawings.

Please refer to Fig. 1, Fig. 2, this device system can transmit the position and the vehicle speed of rail car to a monitoring center 1, and this monitoring center 1 is provided with a receiver 11 and a display screen 12, and then has each factory building and on this screen 12 The configuration diagram of the track, and the utility model is mainly on the track 2 of the factory area, and more than one radio frequency identification chip (RFID Tag) 21 is arranged in each set distance, and the torpedo car is pulled by the locomotive 31 The rail car 3 composed of 32, the locomotive 31 and the torpedo car 32 are all provided with a card reader (RFID Reader+RFID Antenna) 33 and a radio modem (RADIO MODEM) 34, and the radio modem (RADIO MODEM) 34 can wirelessly transmit The signal is transmitted to the receiver 11 of the monitoring center 1 by means of a method, and then displayed on the screen 12 for the personnel of the monitoring center to watch.

With the aforementioned device, when the rail car 3 passes on the track 2, since a radio frequency identification chip (RFID Tag) 21 is set at each set distance, the radio frequency identification chip (RFID Tag) 21 is passed through the rail car 3. Tag) 21, the card reader (RFID Reader+RFID Antenna) 33 on the rail car 3 will read the radio frequency identification chip (RFID Tag) 21, and then transmit it to the monitoring system through the radio modem (RADIO MODEM) 34 The receiver 11 of the center 1 is transmitted to the screen 12 by the receiver 11, and the position and speed of the group of rail cars 3 can be displayed on the configuration diagram on the screen 12, so that the dispatcher of the control center 1 can Clearly and definitely control the current situation of each group of railcars 3, so that when the dispatcher allocates the work of each group of railcars 3, he can make the most appropriate allocation through the current situation displayed on the screen 12, without having to communicate with each other by radio. The crew members on the locomotive 31 communicate with each other, so that the contact time can be shortened, the work efficiency can be improved, and accidents can be avoided more effectively. At the same time, since each set distance is equipped with more than one radio frequency identification chip (RFID Tag) 21, so even if one of them breaks down, the situation that the rail car 3 is not displayed on the screen 12 will still not occur, and because it is read by the radio frequency identification chip (RFID Tag) 21 as Signal transmission, so there will be no similar satellite positioning (GPS), unreceived or poor signal situation.

To sum up, the utility model device has not been seen in the market, and its structure can indeed achieve the purpose of the appeal, and it is novel and progressive. It should have met the requirements of the patent. I would like to file an application according to the law, and I pray to the review committee In detail, Huici is very grateful for the approval of the patent.
