摘要
为消除图书馆中乱占座位的不正常现象,使图书馆资源得到科学合理和有效利用,同时又节约成本,介绍了一种以单片机MEG8为控制核心的基于时分多址技术、主从分布式结构的无线遥测系统。该系统通过主机和各从机在互不重叠的时间段内周期性的通信,将从机探测的座位状态信息送往主机,并由主机完成座位状态信息的接收、显示及更新。充分发挥了单片机、无线发射模块、无线接收模块的性能,具有硬件电路简单、软件功能完善、控制系统可靠的特点。实践证明该系统实现了预期的监测和管理功能。
In order to eliminate the abnormal seat-occupying phenomenon to realize a better utilization of the seat resources in library and simultaneously save the cost, a technique based on the TDMA technology is introduced. The article introduces a kind of wireless telemetry system of master-slave distribution,which takes MCU MEG8 as the controller and accomplishes transmission, display and update of seat status. And it has many advantages, such as the simplicity of hardware circuit, the fully integrated software functions and good reliability. The practice shows the seat management system accomplishes the anticipated monitor and management function.
