Description

 The invention relates to the field of railway management and can be used to obtain information from mobile objects of railway transport that do not have autonomous power sources.

 A known device is selected as the closest analogue for reading information generated on moving objects of railway transport, consisting of passive code sensors with the ability to reprogram the code installed on moving objects, and stationary readers located along the paths (US Pat. RF 2003544, class B 61 L 25/02, publ. 30.11. 93 g.).

 The disadvantages of this device are the ability to receive a signal from the oncoming train through the intercar space of the interviewed train, due to the fact that the interrogating device constantly emits a signal, as well as the lack of determination of wheel sets and the possible opening of containers with cargo.

 The technical task of the proposed device is to expand the functionality and increase the reliability of the information received.

 The technical problem is achieved by the fact that in the device for reading information from moving objects of railway trains, consisting of passive code sensors with the option of reprogramming the code installed on the cars, and stationary reading devices located along the routes, passive transponders for identifying an object with a permanent code, installed on each wheel pair and platform of the car, as well as on the opening parts of the containers and locked shut-off device, while in it introduced a reader enable device located between the rails.

 The operation of the proposed device is implemented using the circuits shown in figures 1, 2, 3, 4.

 In FIG. 1 shows a car 1 in which containers 2 are installed. Passive code sensors 3 are installed on containers 2 with the possibility of reprogramming a code signal, and passive transponders 4 of identifying an object with a constant code are installed on the opening parts of containers 2, which are closed by a locking device. Passive transponders 5 for identifying an object with a fixed code are installed on the platform and each wheel pair of car 1.

 In FIG. 2 shows a block diagram of a passive code sensor 3 with the possibility of reprogramming, comprising a voltage converter 6, a code generation and recording unit 7, a transmitter 8, a transponder 9 with a constant code, a switch 10, and a transmit-receive antenna 11.

 Figure 3 shows a block diagram of a reader 12, comprising a receiving antenna 13, an information receiving and processing unit 14, a power and control unit 15, a generator 16, an inductor 17, a transmitting antenna 18, and a switching device 19.

 Figure 4 shows a diagram of a passive transponder 4 identification of an object with a constant code that closes the locking device containing the transponder 20 with a constant code, connected to it a flexible steel rope 21 and the locking device 22.

 When passing a locomotive of a train consisting of cars 1, along the switching device 19, a signal is supplied to the power supply and control unit 15 of the reading device 12. An inductance coil can be used as the switching device 19, and when the wheeled trolley passes over it, its inductance changes dramatically. The change in inductance serves as a signal to turn on the power supply and control unit 15. Block 15 solves the problem of turning the generator 16 on and off. Block 14 determines the speed of the train, knowing the distance between the first and second wheeled bogies of the locomotive on which the passive transponder is installed, containing information about the serial number and type of locomotive, and the time interval between them passing along the device 19 inclusion. Knowing the speed of the train and the distance from the switching device 19 to the reading device 12, block 14 determines the time interval through which the block 15 must turn on the generator 16. The generator 16 supplies current to the inductor 17, which emits electromagnetic waves through a transmitting antenna 18 with a frequency of 700 kHz up to 2.75 GHz. Once in the range of electromagnetic waves, passive code sensors 3 and transponders 5 and 20 begin to work by re-emitting the code information to the information reception and processing unit 14 of the reader 12 through the receiving antenna 13. The transponders 5 contain information about the serial number of the product, the date of manufacture and about product ownership. The transponder 5 mounted on the platform of the car 1 also contains information about the type of car 1.

 The transponder 20 contains information about the integrity of the circuit, and if the transponder 20, the steel wire 21 or the locking device 22 is damaged, it gives an alarm signal. The passive code sensor 3 receives the signal from the reader 12 using the antenna 11. Through the switch 10, the signal enters the voltage converter 6, to which the transmitter 8 and the code generation and recording unit 7 are connected. Block 7 contains replaceable information about the sender and receiver of the goods, about the points of departure and destination, about the nature of the cargo being transported. The transponder 9 with a permanent code contains information about the serial number of the container 2 and its accessories. In block 14, code signals are processed, an information packet is generated, information is converted to transmit it over the communication line, and the transmission itself is carried out. Block 14, receiving information about the type of car 1, determines its length and, knowing the speed of its movement, calculates the time it passes along the reader 12. After passing car 1 along the reader 12, block 15 turns off the generator 16. Knowing the distance between cars 1 and speed their movement unit 14 calculates the transit time between the carriage through the zone of propagation of electromagnetic waves, after this time, the unit 15 turns on the generator 16. After passing the last car 1 along the switching device 19 block 15 turns off.

 If it is not necessary to obtain detailed information about the cargo being transported, a transponder 5 with a fixed code is installed on the container 2, containing information on the serial number of the container 2 and its accessories.

 Thus, by disconnecting the reader while passing between cars, the possibility of reading information from oncoming trains is eliminated. Due to the installation of passive transponders for identifying an object with a constant code on platforms and wheelsets of cars, it becomes possible to determine on which part of the track re-equipment of the rolling stock could occur. And due to the installation of passive transponders on the opening parts of the containers, the identification of an object with a constant code, which is closed by a locking device, it becomes possible to determine the section of the path on which the container with the cargo was opened.
