摘要
利用基于AT指令的DTU,通过GPRS无线通信网络开发了集中式警用移动数据通信系统。在VB6.0下利用MSComm控件设计了智能通信中心管理软件,可实现智能拨号、对来电号码的追踪、对来电历史记录的查询、对备案数据库以外的来电屏蔽、智能联网、对特密专线拨号以及对特密专线的限权修改等功能。
based at directive DTU, via GPRS wireless communications network has developed a centralized semiautomatic rifle for Police mobile data communications systems. In the VB6.0 exploit MSComm control design smart communication centre management software. You can implement smart dial-up, the calling number tracking, to incoming calls history queries, for the recorded outside the database calls which accounted for electric screening, smart networking, the cryptic special-purpose phone line or communications link dial-up and the power to modify cryptic special-purpose phone line or communications link.
