Bus gate suitable for rail transit industry

The utility model discloses a bus gate suitable for rail transit industry, which comprises an industrial personal computer, at least two equipment modules and at least two node plates arranged corresponding to the at least two equipment modules, the industrial personal computer is connected with each node plate through a twisted-pair bus, the twisted-pair bus comprises a bus data line, a 24V power supply and a ground wire, and the bus data line is connected with the at least two equipment modules. And each node plate is in communication connection with the corresponding equipment module. According to the utility model, a four-wire system RS485 communication mode is adopted as a bus type communication mode of the ticket checker, so that: 1, a bus can transmit and receive data in real time without occupying a channel like a traditional RS485 communication mode, and a full duplex serial data communication mode is realized; 2, a power line is integrated in a bus, a large amount of redundancy of wires is reduced,
