Description

The invention relates to the field of railway and mine rail transport and can be used to automatically read information about the number and direction of movement of transport units.

A device is known for automatically determining the number and direction of a moving mining locomotive, according to ed. St. No. 391957, containing a locomotive-mounted transmitter consisting of a radiator connected via a transmission amplifier and a modulator to a code signal generator, a carrier frequency generator connected to a modulator, a receiver located at the control point, which is connected from the receiving antenna of the train number through a high-frequency amplifier, a detector, a low-frequency amplifier, frequency selectors, memory blocks and a relay locomotive number indicator, a relay number signal amplifier of a train connected to memory blocks and builder duration signals deschifratoru and transistor switch, a receiving antenna signals the direction of movement, is connected through a high frequency amplifier, a relay amplifier transistor to the direction of movement of the key and deschifratoru, the inlet of which is incorporated relay 1 direction.

A disadvantage of the known device is the low reliability of the received information due to the influence of impulse noise in the reception path.

The purpose of the present invention is to increase the accuracy of the device.

This goal is achieved by the fact that the device is equipped with a generator of pulses for resetting memory blocks and logic elements AND, NOT and DELAY, while the generator output is connected to the memory blocks and the output of the signal duration generator, and the generator input is connected to the output of the logic element AND, the first the input of which is connected directly, and the second through serially connected logic elements DELAY and NOT, to the output of the transistor switch and to the inputs of the frequency selector.

The drawing shows the functional diagram of the device.

The device consists of a transmitter 1, installed on an electric locomotive, and a receiver 2. settling in the workings of HiaxT along the path of the electric locomotive.

The transmitter 1 consists of a frequency generator 3, a modulator 4, a high frequency amplifier 5, an antenna b, and coding generators 7-10.

Receiver 2 consists of antennas II and 12, high-frequency amplifiers 13, 14, a detector 15, low-frequency amplifiers 16, frequency voters 17-20, memory blocks 21–24, relay 25--28 numbers of an electric locomotive, relay amplifiers 29 and 30, a transistor switch 31, a ZADG1RZHK logic element 32, a NOT logic element 33, an AND logic element 34, a controlled pulse generator 35, a generator 36, a signal duration generator 37, a motion direction relay 38, 39.

The device works as follows.

The locomotive number is represented by, for example, a four-digit code and is dialed by connecting in appropriate combinations of encoding 7-10 to the input of the modulator 4, where the high-frequency signal from the carrier frequency generator 3 is fed.

Pro.modulated signal through the high-frequency amplifier 5 is fed to the antenna 6.

When passing an electric locomotive with a non-distributor 1 at the control point, the signal is sensed by antennas 11 and 12 and is fed to high-frequency amplifiers 13, 14. After amplification, signals are fed to relay amplifiers 29 and 30, the response of which determines the communication zone of transmitter 1 with antenna 2. Depending on the direction of passage of the locomotive in the communication zone, the sequence of the signals to antennas 11, 12 changes. In one case, at the inputs of de jiftoropa 36, signals are given in TC in the OO, O-1, 1 - 1, 1-O, O-O sequence, and in the other case, in the OO, 1-O, I sequence I, O-1, O-0. As a result, at the output of the dust generator, one or the other signals, respectively, are switched on in ms, which include the corresponding movement direction relays 38 or 39.

The signal received by the antenna 11 through the high-frequency amplifier 13 is sent to the detector 15. The demodulated signal through the amplifier 13 is fed to the detector 15. The demodulated signal through the low-frequency amplifier 16 is fed to parallel-connected inputs of frequency voters 17-20 controlled by a transistor power supply circuit key 31. The signal at the output of the transistor switch 31 is on Wits since the entrance of the electric train into the communication zone, since the control strings are fed to it from the relay amplifiers 29 and 30.

If there is a frequency of coding oscillators 7-10 in the spectrum of a demodulated low-frequency signal, the corresponding frequency selectors are triggered. The signals from the output of the frequency voters are sent to blocks 21-24 and further to the relay 25-28 nbmera locomotive, which are triggered by the receipt of signals from memory blocks and by the signal from the generator 37 of the signal duration. When a dejfrater 36 is triggered, its output signals are differentiated and are set to trigger the imager 37 for the duration of the signal. Thus, the recorded information will be output to the display unit 40 of the display when the encoder 36 is activated, i.e. when the locomotive leaves the communication zone.

The transfer / rewind of memory blocks 21–24 to the initial cocTOHHi-i is carried out by a backward ejection pulse, obtained by differentiating the output signal of the duration generator 36. In addition, before the electric locomotive enters the communication zone, the pulse obtained by differentiating the output signal of the relay amplifier 29, another reset of the memory blocks is performed.

During the time when the electric locomotive is in the communication zone, from the output of frequency voters to the inclusion of the block numbers corresponding to the code, triggering pulses are constantly received by us.

For from noMex, an additional reset by a series of pulses is introduced into the device at the time of transient processes, which is carried out in the following manner. The controlled pulse generator 35 in the initial state is in the decelerated state, and when the transistor switch 31 is triggered, i.e. when the locomotive enters the communication zone, it is turned on by the 34 I logic element. After the time of the triggered 32 1 DELAY triggered, which is equal to or slightly longer than the frequency electoral transients, the output signal is not output, but the therefore, the controlled pulse generator will return to the initial state.
