Description

one

The invention relates to transport automation and is intended to control devices for automatically reading information from moving rolling stock.

A device is known for controlling the readout of information from vehicle assemblies, containing triggers with two stable states, a counter of read numbers connected to one input of two logical elements OR fl.

However, this device includes an actuating element during the passage of all, without exception, the mobile units included in the composition, and is in the switched on state for a time often exceeding that required for identification of the composition. In fact, if the composition, following the point of the previous reading, remains unchanged, it is sufficient to consider one or two mobile units and, by that, set the course for this composition of the reading point.

The purpose of the invention is to reduce the reading time.

The goal is achieved by the fact that the device is equipped with a pulse shaper, the output of which is connected to the counter and one input of the first trigger, and the device enters the contacts of the track relay, the contacts of the shunting relay, the contacts of the output signal and the contact of the closing relay of the read section through which one output the first trigger is connected to another input of the first logical element OR, connected by the output to the code input of the second trigger and, through the contacts of the relay relay, to the formation of some pulses, while the second first trigger stroke podklyu5 chen to power supply via series connected contacts track relays and shunting routes, and its outputs connected to inputs of the second OR gate whose output is output through the relay contact is connected to another input of the second flip-flop.

The drawing shows a block diagram of the device.

The device contains contacts 1 and 2 of the nyTeBOiO relay, contacts 3 and 4 of the relay route of the shunting route, contact 5 of the signal relay of the output signal and contact B of the short-circuiting relay of the section read. One input first

the trigger 7 | with two stable states through contacts 1, 3 and 4 is connected to the power source and its outputs through the first logical element OR .8 and pin 5 are connected to one input of the second trigger 9 with two stable states. The output of the driver 10 pulses through contact 2 is connected to the output of the second logic element OR 11, and the output to other inputs of the trigger 7 and the input of the counter 12 of the number of read numbers. The output of the logic element OR 11 is connected to the second input of the trigger 9, and the inputs to the output of the trigger 7 via the contact bis output of the counter 12.

The device works as follows.

In the initial state, when there is no train on the track and a closed output signal, contacts 1, 3, 4, and-5 are open, 2 and b are closed, and triggers 7 and 9 with two stable states are in the O state. If there are maneuvers on the train, as evidenced by the contacts of the track relay and the relay registering the route setting to or from the track, the first trigger 7 is transferred to 1 state. After starting the shunting movement, contacts 3 and 4 are opened, but the trigger 7 remains, in 1 state. The voltage from its .1 output through the closed contacts 6 of the relay and the second logic element OR 11 provides the state of the second trigger 9, which corresponds to the off state of the reader. Opening the output signal from the path leads to the opening of the contact and removing the voltage from O of trigger input 9, and the voltage from 1 trigger output of 7 through the logic element OR 8 and the closed contact 5 of the signal relay is fed to 1 trigger input 9, which switches in 1 state and includes a reader. Following the overlap by the train of the output signal, the clock cycle 5 of the synal relay opens, but the flip-flop 9 remains in 1 state. After the train clears the way, contact 1 is closed and contact 2 of the track relay closes. The release of the train station where. a readout device is installed, causes contact 6 to be closed. Voltage from 1 trigger output 7 via terminal b and the logic element OR 11 flips trigger 9 into the O state. At the same time, through the contact 2 of the track relay, the voltage is fed to the input of the pulse driver 10, which produces a pulse, flip-flop trigger 7 and O state, and checks the initial state of the counter 1 of the number of read numbers. So

thus, a complete reading of the train composition is carried out. The counter 12 of the number of read numbers with full read does not work. In the absence of maneuvers, the first trigger 7 remains in the O state. When the output signal of the output signal relay is contacted through the logic element OR 8, a flip-flop .9 is switched to 1 state, which turns on the reader. The second trigger 9 remains in 1 state until the counter 12 of the number of read numbers counts a predetermined number. It is chosen for reasons of ensuring the required reliability of information and, ideally, i.e. in the absence of distortion of the numbers of mobile units, is equal to one. In reality it is somewhat more.

If the number of actually read numbers coincides with the counter 12 installed, the OR 11 logic element sends a signal to the O input of the trigger 9 and transfers it to the O state, since by this time the pin 5 of the signal relay is already open. The reading is stopped by limiting to several numbers (less often partial reading). Through pin 2 of the track relay, as soon as the path is cleared, the signal from the output of the counter 12 of the number of read numbers also enters the input of the driver 10 pulses of a pulse which leads the counter 12 to the initial state. The first trigger remains in the About state. Thus, the device returns to its original state.

The proposed device implements a method in which a reading volume is predetermined by a shunting movement. In the presence of shunting movements, the composition is read in full, and in the absence, in part.
