Abstract

The invention discloses a safety controller sub-rack of a 2-out-2 vehicle-mounted signal system. The safety controller sub-rack comprises a first EPCM board card, a second EPCM board card, a first power supply module, a second power supply module, a network pinboard, a channel selection switch jumper board, a first ETH / CAN conversion module jumper board, a second ETH / CAN conversion module jumper board, a mother board and two or more Ethernet M12 interfaces. Compared with an existing 2-out-3 system, one EPCM board card is omitted, and an original controller sub-rack and an external CAN interface are changed into the Ethernet interfaces. The invention further discloses a storage structure of the safety controller sub-rack of the 2-out-2 vehicle-mounted signal system. The storage structure comprises a cuboid shell, the length of the storage structure is 482.6 mm, the height of the storage structure is 133 mm, and the width of the storage structure is 320 mm. The structure is safe, reliable and standard, the size is reduced, cost is lowered, plugging and unplugging are convenient, and accidental plugging errors can be prevented.

Description

technical field

[0001] The invention relates to a train control signal system, in particular to a safety controller sub-frame in a vehicle-mounted control device for a 2×2-out 2 train. Background technique

[0002] The safety controller subrack (MPU) of the on-board signaling system is an important device in the on-board equipment of the CBTC signaling system. As the main controller in the on-board equipment, it can control all functions required by the automatic train control (ATC). The existing system is a 3 out of 2 system. Although the redundancy is already high, compared with the 2 by 2 out of 2 system, the operation requirements of the 2 by 2 out of 2 system are more stringent and have higher redundancy. In the existing 2 out of 3 system, there is no redundancy for devices such as interrogator (TI) proximity sensors, proximity sensors, etc. Customers' inclination towards 2 by 2 has become a trend. In addition, in the existing system, the communication between the MPU...
