Description: Zigbee是IEEE 802.15.4协议的代名词。根据这个协议规定的技术是一种短距离、低功耗的无线通信技术。这一名称来源于蜜蜂的八字舞，由于蜜蜂(bee)是靠飞翔和“嗡嗡”(zig)地抖动翅膀的“舞蹈”来与同伴传递花粉所在方位信息，也就是说蜜蜂依靠这样的方式构成了群体中的通信网络。其特点是近距离、低复杂度、自组织、低功耗、低数据速率、低成本。主要适合用于自动控制和远程控制领域，可以嵌入各种设备。简而言之，ZigBee就是一种便宜的，低功耗的近距离无线组网通讯技术。
-Zigbee is synonymous with the IEEE 802.15.4 protocol. According to the agreement of the technology is a short distance, low-power wireless communication technology. The name comes from the bee character dance, as bees (bee) is flying by and the " buzz" (zig) shake the wings of the " dance" to transfer pollen with peers where the position information in such a way that bees rely on constitute a group communication network. Its characteristics are close, low-complexity, self-organizing, low power, low data rate, low cost. Mainly suitable for automatic control and remote control, can be embedded in various devices. In short, ZigBee is a cheap, low-power short-range wireless network communication technology group.

Description: ZigBee是基于IEEE802.15.4标准的低功耗局域网协议。根据国际标准规定，ZigBee技术是一种短距离、低功耗的无线通信技术。这一名称(又称紫蜂协议)来源于蜜蜂的八字舞，由于蜜蜂(bee)是靠飞翔和 嗡嗡 (zig)地抖动翅膀的 舞蹈 来与同伴传递花粉所在方位信息，也就是说蜜蜂依靠这样的方式构成了群体中的通信网络。-ZigBee is a low-power LAN protocols based on IEEE802.15.4 standard. According to international standards, ZigBee technology is a short distance, low power consumption of wireless communication technology. The name (also known as the purple bee protocol) derived the eight words dance of bees, as the bees (bee) is by fly and \ buzz\ (zig) to \ dance\ of wings with peers transfer pollen location information, that is to say, the bees depend on this way constitute the communication network in the group.

Description: 对高精度短距离测量的需要，以现场可编程门阵列(FPGA)为控制核心，采用高精度时间数字
转换芯片TDC—GPl和433 MHz超再生射频发射、接收模块，设计了一种高精度的到达时间差(TDOA)测距
系统。该测距系统由发射节点与接收节点组成，其中发射节点由FPGA控制433 MHz超再生射频信号与
超声波信号的同步实时发射；接收节点将接收的射频信号与超声波信号，经过TDC．GPl进行TDOA测量，
并由FPGA完成对TDC—GPl的测量参数配置、测量结果读取及串口上传到上位机。该测距系统由Zig Bee
无线通信模块对发射和接收模块进行测量过程协调，并对超声波传播速度进行温度补偿。实-Design of rI]DOA ranging system based on FPGA and TDC-GPl木
