摘　　要：查询应答器是一种具有综合利用价值、保证列车运行安全、提高运输效率的重要基础设施。文中介绍了查询应答器的一般性原理 ,包括应答器的几何尺寸与车载设备接收数据帧大小的关系、数据传输率与循环冗余校验等。并给出了应答器用于提速的一般性方案。同时根据广深线地面信号及 L SK列车分级速度控制系统的特点 ,提出了应答器与机车信号及 L SK列车自动控制系统相结合用于该提速区段的方案。经试验表明 ,经过修改后的 L SK系统软件 ,除原有功能保持不变 ,可以在应答器提速区段完成提速功能外 ,并能在该区段提速完成后可靠恢复原有的 L SK控车模式。这个方案是国内首次在既有运营线上成功试验运行的点式与连续式信号结合的控车模式 ,安全上具有硬件和软件两个层面的防护 ,是故障导向安全的。Balise system is a very important basic system that has many advantages to be used by various kinds of lines to improve transportation efficiency and assure of safe operation. The paper describes the basic principles about the balise system, including the relationship between the size of balise and retrieved data frames of on board computer. There are several important concepts of the balise system, such as information frame format, data transmission rate and message cyclic redundancy checks. The paper introduces general methods using balise for the purpose of speed increase. At the end of the paper, we recommend some kinds of methods, which can be used in high speed or speed increase lines when the balise system is used with Cab signal and LSK train automatic control system. The methods are successfully tested on the Guangzhou Shenzhen line. The experiment proves that the LSK automatic train control system can increase or limit train speed safely and reliably after the software of LSK system is modified. The LSK system can come back to its original control mode when it passes the speed increase section. This is the first running test to automatically control train speed in combination with the intermittent signal or continuous signal on the Chinese railway. As for the fail safe function, there are two aspects in hardware and software to guarantee safety when failure occurs.
