| description | Zone controller(ZC) subsystem in the communication based train control(CBTC) system is a full-time continuously working equipment, which is in the center of data interaction of the whole system. ZC system log can generate up to 10 GB data per day in operation that brings great pressure on storage and dumping. In this case, according to the characteristics of ZC record data, a software compression algorithm was proposed to compress the stored data, which aimed to reduce the space of data storage. The results show that the compression algorithm can compress data by 30%. Storage capacity of the system is effectively improved, and the workload of data dumping is also reduced. |
