Access Point Research in Rail Train Safety Monitoring Sensor Network

Rail train safety monitoring sensor network is an important screen of guaranteeing the train safe, efficient, and reliable operation, the access point and fusion point are data transmission confluence center of the train safety monitoring sensor network, so reasonable configuration to the access point and fusion point has great significance to ensure the train safety operation. In this paper, basis on the existing city rail train safety monitoring network research results, analyzed and researched the function structure and performance index of access point.
