Train receiving unit for an automatic alarm system

摘要

The train receiving unit for an automatic alarm system refers to the receiving equipment of automation and remote control of rolling stock of rail vehicles. The solution is designed to determine the signals in front of traffic lights, the state of the arrows and other travel devices, or to indicate the distance between trains. The block contains a receiving head per unit of rail rolling stock. The head includes a primary transducer of a magnetic field into an electrical signal, an amplifier, and a housing. The converter consists of a single-coordinate non-inductive sensitive element. The output element is connected to the input of the amplifier. The hub, converter and amplifier are placed in a common housing. The hub, converter and amplifier are located in close proximity to each other. The sensing element of the transducer is oriented from the condition of the predominant perpendicularity of the axis of its coordinate to the longitudinal axis of the rail. The signal-to-interference ratio for the analog path of the locomotive device has been increased. Achieved a high noise immunity of the locomotive APS device on the background of additive interference. 3 hp f-ly, 7 ill.
