Embodiment Construction

[0015] Such as figure 1 As shown, the present invention includes a signal system 11 and a shielded door system 12, and the door opening command and the door closing command are controlled by safety relays KA1 and KA2 through double-break mode output through safety relays KA5 and KA6. At the same time, at the internal interface of the screen door system 12, KA1~KA4 jointly constitute a logic processing circuit to complete the processing of invalid combinations of the signal system, and finally output the switch door signal A.

[0016] The above-mentioned signal system 11 includes a door opening signal input point open and a door closing signal input point close, wherein the door opening signal input point open is connected to the fifth safety relay KA5, and the normally open contact of the fifth safety relay is connected in series in the circuit of the first safety relay KA1 , the door closing signal input point close is connected to the sixth safety relay KA6, and the normally...

Abstract

The invention relates to an improved interface circuit of a shielding door system and a signal system. The interface circuit comprises the signal system 11 and the shielding door system 12, wherein door opening commands and door closing commands are output through safety relays KA5 and KA6 in a double break manner to control safety relays KA1 and KA2. Meanwhile, KA1, KA2, KA3 and KA4 collectively constitute a logic processing circuit at an internal interface of the shielding door system 12 to process the invalid combination of the signal system and finally output door opening / closing signals A. The improved interface circuit adopting the technical scheme has simple structure and only uses four relays to realize the logic processing function which can be realized through software programming. The relays are safety relays and all the realization circuits are hard-wired and have high reliability. Compared with the software realization manner, the realization cost of the invention is low.

Description

technical field [0001] The invention relates to the technical field of platform screen doors of urban rail transit, in particular to an improved interface circuit between a screen door system and a signal system, which can avoid malfunction of the screen door system caused by a failure of the signal system and prevent dangerous accidents . Background technique [0002] The platform screen door system of urban rail transit is an essential facility for modern rail transit projects. In order to ensure the safety of passengers and lay the technical foundation for unmanned driving, the platform screen door system of urban rail transit and the automatic train control system must realize linkage control. On the other hand, from the perspective of improving subway operation efficiency and reducing the driver's work intensity, platform screen doors should also be automatically opened and closed synchronously with train doors. The main way to realize this function is the signaling sy...
