Abstract

The embodiment of the invention provides a fixed block and quasi-moving block compatible communication based train control (CBTC) vehicle-mounted system. The CBTC vehicle-mounted system comprises vehicle-mounted automatic overspeed protection ATP equipment with a CBTC function, ATO equipment with a CBTC function, a transponder receiving unit with a CBTC function, a WLAN / LTE unit, a radar and a speed sensor and further comprises a rail circuit reading unit, wherein the ATO equipment, the transponder unit, the WLAN / LTE unit, the radar, the speed sensor and the rail circuit reading unit are all connected to the vehicle-mounted automatic overspeed protection ATP equipment. According to the fixed block and quasi-moving block compatible CBTC vehicle-mounted system, the defects that in the prior art, the rail transportation fault rate is high, and maintenance pressure is large are overcome. A train can operate under CBTC moving block. Subway transformation comprises the two steps of train transformation and ground equipment transformation, subway faults can be reduced gradually, the transformation cost can be halved in several years, and large-number fund pressure in the short period is reduced.

Description

Technical field [0001] The invention relates to the technical field of rail transit control, in particular to a CBTC vehicle-mounted system compatible with fixed and quasi-mobile blocking. Background technique [0002] Rail transit technology has transitioned from fixed and quasi-mobile block to mobile block based on wireless communication-based train control (Communication Based Train Control, CBTC). At present, almost all rail transit construction at home and abroad adopts CBTC mobile block. However, the existing lines have defects such as equipment aging, high failure rate, and low operating efficiency. The owner hopes that the existing fixed and quasi-mobile blocked lines can be upgraded without affecting normal operations to reduce the failure rate, Improve operational efficiency and reduce the maintenance of old equipment. [0003] For example, Beijing Metro Line 5 starts from Songjiazhuang Station in Fengtai District in the south and ends at Tiantongyuan North Station in Ch...
