Abstract: Due to the differences in the system of the owner's trackside equipment and in the driver's habits of controlling the train, the speed control logic of onboard equipment of the project in Sao Paulo, Brazil is quite different from that of the traditional onboard equipment in China. In view of this situation, this article studies the speed control and protection logic of FZL300 onboard equipment based on the application requirements of foreign urban rail owners and trackside equipment standards, in order to fulfill the functions of automatic train protection and speed-control conversion between high and low speed sections.

Key words: automatic train protection, onboard equipment, speed control protection

摘要： 巴西圣保罗项目由于业主地面设备制式及司机控车方式习惯，导致其与国内传统的车载设备控速逻辑存在较大差异。针对此情况，研究基于国外城轨业主应用需求及地面设备制式的FZL300车载设备控速防护逻辑，实现列车自动防护、高低速区间控速转换等功能。
