Embodiment 1

[0030] like Figure 1 to Figure 9 As shown, a positioning reader redundant control system includes a switch 1 and an on-board controller 2, an antenna 3, a first TI host 4, and a second TI host 5 electrically connected to the switch 1, respectively, The switch 1 can select one of the first TI host 4 and the second TI host 5 as the working TI host to realize switching between the master and the standby.

[0031] As a preferred technical solution, the switch 1 includes a switch control board 11 , a switch power supply 12 , a radio frequency switch 13 , and a controller panel 14 electrically connected to the switch control board 11 , respectively.

[0032] As a preferred technical solution, the switcher control board 11 includes a switch control circuit, a control board power supply circuit electrically connected to the switch control circuit, a switch switch circuit electrically connected to the switch control circuit, and a switch circuit electrically connected to the switch co...

Embodiment 2

[0040] like Figure 1 to Figure 9 As shown, as a further optimization of Embodiment 1, this embodiment includes all the technical features of Embodiment 1. In addition, this embodiment also includes the following technical features:

[0041] The technical problem mainly solved by the present invention is that in the operation process, hardware failure occurs due to the hardware failure of the positioning reader host, the attenuator, the cable or the connector between the positioning reader host and the decoder board (TIC) in the vehicle positioning system. , Redundant design is realized by adding switchers and beacon reading systems, and the positioning reader hardware backup scheme is adopted, which can be used when the positioning reader, positioning reader to TIC board, TI side coaxial cable connector, attenuation When the hardware such as the device fails, it can quickly repair the failure, reduce the impact of the failure, and avoid the occurrence of midway clearance or l...

Abstract

The invention relates to the technical field of rail traffic control, and discloses a positioning reader redundancy control system which comprises a switcher, and a vehicle-mounted controller, an antenna, a first TI host and a second TI host which are electrically connected with the switcher respectively, and the switcher can select one of the first TI host and the second TI host as a working TI host to realize switching between the host and the standby. According to the invention, the problem that the operation efficiency is seriously influenced when the positioning reader fails in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to a positioning reader redundant control system. Background technique [0002] In the current mainstream rail transit train automatic control system, the on-board positioning reader (hereinafter referred to as: TI) is generally single-ended and operated in a single-machine configuration. The on-board system positioning reader belongs to the core key equipment in the subway signal positioning system. , When the positioning reader fails, it will cause the entire train positioning system to fail. If it cannot be recovered in a short time, the operating train will run in the degraded mode, and the train can only continue to run in the restricted manual mode or the unrestricted manual mode, which will seriously affect Operational efficiency. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the present invention provides a redundan...
