摘要
呼叫系统被广泛应用在各种场合,针对呼叫系统中人员位置确定和呼叫处理等问题,设计出一套基于Zigbee定位技术的无线呼叫系统。该系统具有人员定位、呼叫处理和自动通知等功能,采用CC2530模块作为固定设备,CC2431模块作为移动设备,通过RSSI定位方法确定移动设备位置。由上位机软件处理呼叫命令,通过比较设备间距离选择与呼叫设备距离较近的服务设备,达到快速响应呼叫的目的。
Wireless calling system is widely used in many situations. A new wireless calling system based on Zigbee wireless location technology for person localization and call processing is proposed.This system could achieve personel positioning, au- tomatic notification, calling and dealing with requests. It adopted the CC2530 module as the fixed device and CC2431 module as the mobile device, located the mobile device using RSSI location technology.The calling request was processed by upper PC software and would be responded quikely by choosing the nearest service equipment after comparing the distance between de- vices.
