| 摘 要： | 提出了一种基于CC2430的便携式无线搜救器的设计方法。该设计方法根据佩戴在遇难人员身上酬CC2430射频卡发往搜救器的无线数据帧所含的RSSI值，通过数学转换为遇难人员与搜救器之间的盛离，从而判断出两者之间的距离以及遇难者所处的位置，并且运用调度算法优化了通信，增加了在通钷繁忙时的数据传榆的稳定。实验证明，该设计方法具有良好的精度和灵敏度，满足实际应用的要求。

| Abstract: | A design method of the portable wireless searcher based on CC2430 is proposed. In this method, the values of RSSI of the wireless data frames from CC2430 RF card on the person in trouble sent to the searcher are changed into the distance values between the person in trouble and the searcher by mathematic transform, thus the above distance and the location of the person are estimated. Furthermore, this method uses schedule algorithm to optimize the communication and improve the stability of the data transmission in busy com- munication. The experiments show that the design method provides good accuracy and sensitivity, and can meet the requirement in reality. |
