Abstract: The onboard ATC main control equipment of Sao Paulo Line 13 in Brazil is a non redundant structure, and only the speed sensors and accelerometers are redundant of head and tail. Therefore, when the main control equipment in the main cab fails, it will lead to the end cannot be used normally, which seriously affects the operation efficiency. This paper puts forward a redundancy design of single set of equipment, which is easy to implement, through two aspects of hardware transformation and software optimization,  to realize the function of hardware redundancy and software hot standby, and further improve the equipment redundancy and system availability. The scheme has been implemented in the field.

Key words: onboard ATC, head and tail redundancy, equipment redundancy

摘要： 巴西圣保罗13号线项目车载ATC主控设备为非冗余结构，仅对速度传感器和加速度计进行首尾冗余，因此当主驾驶室主控设备发生故障时，将导致该端无法正常使用，严重影响现场运营效率。通过硬件改造和软件优化两方面，提出易实施的单套设备冗余设计，以实现硬件冗余和软件热备的功能，进一步提高设备冗余性和系统可用性。
