摘要: CTCS-3与CTCS-2等级下动车组允许速度分别为300~350km/h与250~300km/h,无线通信超时会导致动车组由CTCS-3等级降为CTCS-2等级,严重影响动车组允许速度以及行车许可、移动授权等控车数据的实时传输。为准确分析无线通信超时原因,分别从地面设备、车载设备、无线网络3方面对无线通信超时进行举例分析,并提出优化建议。

Abstract: The allowable speed of EMU under CTCS-3 and CTCS-2 levels is 300-350 km/h and 250-300 km/h respectively. Wireless communication timeout will lead to the fallback from CTCS-3 to CTCS-2 level, which will seriously affect the allowable speed of EMU and the real-time transmission of train control data such as allowable speed of EMUs and Movement Authority (MA). In order to accurately analyze the causes of wireless communication timeout, this paper analyzes the cases from three aspects of ground equipment, on-board equipment and wireless network, and puts forward optimization suggestions.

Key words: wireless communication timeout, ground equipment, on-board equipment, wireless network
