Abstract

The invention discloses a long range active response loop wire set, which is used in the field of railway signal automatic control to account for the difficulty of changing the command of controlling vehicles and answering machine receiving, detecting and maintaining system in the existing technology. This set includes electrical design which is compatible to European standard about the basic function of the active answering machine, and the elongated active response loop wire design. In this invention, the active response loop wire set is installed in the middle of two steel rails to replace standard answering machine, the loop wire of this set is as long as 4 meters, the parameter of electric resonance point is 4.23 MHz, this set can send 4.23 MHz FSK carrier frequencies semaphore which is compatible to standard answering machine to railway engine. After using this invention, the rigor request of railway engine positional accuracy can be relaxed, which is indicated that as long as the railway engine stops at the active response loop wire set of 4 meters long, information continuously received can be implemented, greatly reduces the railway engine position request when change the command of controlling machine and the answering machine implements receiving, detecting, maintaining and employing.

Description

technical field

[0001] The present invention relates to the field of automatic control of railway signals, in particular to an innovatively designed long-action-distance active response to the problems encountered in the application of the European standard transponder system in our country about the continuous transmission of vehicle control instructions and equipment inspection and maintenance. Ring device. Background technique

[0002] In the train control system of urban rail transit, the locomotive positioning is realized through the transponder system, and the shunting command is realized through wireless data transmission. When the wireless data transmission system fails, the wireless shunting is realized through the active transponder. command supplement. For example, when the locomotive turns back, if the wireless system fails, it is necessary to transmit the shunting order through the active transponder, but in the existing situation, the effective range of the tr...
