The invention relates to measuring techniques and can be used in railway transport control systems. A device for reading information from moving objects comprises a sensor installed on an object comprising a transceiver antenna, a processing/transmission information unit, a primary converter, an analogue-to-digital converter and a power supply unit, also a receiver installed at stations for reading information, comprising a transceiver antenna and an information receiving unit. Moreover, the sensor comprises an SHF electric wave receiver, an operation amplifier and a rectifier. The processing/transmission information unit is performed as a microcontroller with a radio transmitter. The transceiver antenna is connected to a magnetic wave receiver with a power supply unit, which is connected to an operation amplifier, the analog-to-digital amplifier, the processing/transmission information unit and the primary converter correspondingly. The primary converter is made as an open magnetic core with two windings, which are connected to a sin voltage generator and through a capacitor to the primary transformer winding, the secondary winding of which is connected to the rectifier. The rectifier is connected to the operation amplifier, which is through the analog-to-digital converter is connected to the processing/transmission information unit connecting to the antenna. Moreover, the SHF power amplifier, the microcontroller with radio-receiver and path-control transducer or a track circuit are connected to the receiver. The microcontroller input is connected to the radio-receiver and path-control transducer or track circuit and information receiving unit, connected to the antenna, the outputs – to the power amplifier connected to the antenna and local calculation system. The device provides enhancement of information reading accuracy and and information volume expansion that increases reliability of work. |
