Description

one

The invention relates to devices for automation and tele-mechanics in railway transport and can be used in a go-to, hand-held automatic central: iz | TsI1I.

There are known devices for combing, rolling of arrows in the system of automatic centralization of the hump, containing: I-track sensors installed in the control section, driver of impulses, axle counter in the control section and axle counter in half of the long-wheel car, splitter grgger, inverters, switch track, relay, arrow control circuit and power supply.

The proposed device differs from the known ones in that it is equipped with a control relay, a signaling circuit for the passage of a long-base car, a coincidence circuit, a control trigger and an IH | Be, rtoras. The winding of the control relay is connected via an inverter to the outputs of the axle counter in the control section. The input of the arrow control circuit is connected to the power source through a series of normally closed contacts of the switch track and control relay, and the input of the signaling system for the passage of a long base car is connected to a power source through the series connected front contact of the relay track relay, the rear contact of the control relay, inverters. One inlet of one inverter is connected to the output of the control trigger, the other c) the course of which is connected to the input of the signaling system of the passage of the long-base car and through the inverter is connected to one of the inputs of the coincidence circuit. The first three inputs of the latter are connected respectively to the outputs of the pulse former and the axle counters in the control section and in the half of the long-haul car, and the output is connected to the input of the control trigger. This P0 | above is put on the post and the efficiency of the device.

The checkout shows the block diagram of the proposed facility. In 1V | PCM of the car passage through track sensors I and 2 of the control section 3 by means of a formagatel 4 pulses, a 5-axis counter on the control section, a dividing trigger 6 and an 7-axis counter in the driver’s wagon, the signal relay 9 de-energizes If there are no failures in the counting of the axes of the traceable car, then through the matching circuit 10 the control trigger // is kept in the initial state when the inverter 12 is open, and the signal to the health circuit 13 arrives.

Closing of contact 14 switch-track relay and opening of contact 15 of the relay

9 causes the inverter 16 to open, the alternator 17 closes, and the circuit 18 notifies the operating personnel of the driving position in the direction of the new base car. The arrow free signal is transmitted to the arrow control circuit 19 via make contacts of 14 liters 15.

The operability of the device is monitored by checking the mutual state of the counters 5 and 7 during their transitions to the next stable position. If during normal operation of the counter 5, the counter 7 is not removed from the initial state, then the control pulses from the imaging unit 4 arrive at the counting input of the trigger //. This leads to a de-energized / io relay 9, KoiTOpoe excludes the supply of executive commands to skim 19 arrow control. The same dependence is realized when the counter 5 remains in its original position when the axes are approached in section 3.

(Subject invention

A device for controlling the separation of dividing arrows in the system of the hump a and, at the same time, static centralization, containing path sensors installed in the control section, a pharm of pulses in the control section, axle counters in the control section and a counter in half, ro wagon, breakaway trigger, inverters, switch track relay, how to control the arrow and power supply, characterized in that, in order to increase the reliability and efficiency of the device, it supplied the control relay with a silnualization circuit and a pass for car, circuit SO | Bade 11i, control trigger, and inverters, with the winding of the control relay connected via an inverter to the inputs of the axle counter in the control section and the axle counter in the long-basic car section, control circuit input the arrow is connected to the power supply through, a series of normally closed contacts of the switch track and control relay are connected in series, and the signaling signaling circuit of the passage of the long-wheel car is connected to the power source through the series-connected front contact kt dial track relay

rear contact of the control relay, inverters, with one input of one .inverter connected to the output of the control trigger, the other output of which is connected to the input of the signaling circuit of the passage of the long-base car and

the inverter is connected to one of the inputs of the coincidence circuit, the first three inputs of which are connected respectively to the outputs and the driver of the pulses and axle counters in the control section and in half of the long wheelbase car, and the trigger is connected to the input of the control trigger.
