FIELD: railway transport. ^ SUBSTANCE: proposed device contains transmitting antenna arranged at beginning of each block-section and connected with generator, and receiving antenna connected with data reception unit, turning angle pickup installed on wheel axle box and connected with inputs of distance meter and speed meter, brake efficiency meter, program speed unit and three-position relay unit, all mounted on locomotive. Brake efficiency meter is connected to outputs of acceleration meter and pressure pickup in brake main line. One input of program speed unit is connected with output of distance meter, second input is connected with output of data reception unit, third input is connected with output of cab signaling unit, and fourth input, with output of brake efficiency meter. Three-position relay unit is connected to train brake system brake and release valves. Device is furnished with read-only memory unit, track block-section limit shaper and wheelset tyre diameter meter. One input of wheelset tyre diameter meter is connected with output of pickup, second input, with second output of data reception unit and third input, with first output of read-only memory unit, and outputs are connected to inputs of distance meter and speed meter. Second output of read-only memory unit is connected with input of brake efficiency meter, and third output is connected with fifth input of program speed unit and each of its two inputs is connected, respectively, with third output of data reception unit and track block-section limit shaper. Input of track block-section limit shaper is coupled with output of automatic cab signaling unit. ^ EFFECT: improved accuracy of speed control and train braking, enlarged operating capabilities. ^ 3 cl, 1 dwg |
