摘　　要：在车辆监控系统中,监控中心需要与数量庞大的车载终端进行数据通信,造成大量线程同时访问数据库,严重影响了系统的运行效率和性能。为了解决这个问题,在监控系统的软件结构中设计了带有多线程安全、高效机制的数据集合缓存器。该缓存器不但缓解数据库的访问压力,提高运行速度;也增强了系统的可靠性。In the vehicle monitoring system, the monitoring center needed to communicate with the huge number of car terminals, which caused a lot ofthreads access database. As a result, it seriously influenced the operation efficiency and performance of the system. In order to solve this problem, thepaper designed a collection of data cache containing multithreaded safe and efficient mechanism in monitoring system software structure. The cache notonly alleviated the database access pressure and increase speed, but also improved the reliability of system.
