无线跳频通信系统下无线接入点故障检测设备

针对在对无线跳频通信系统进行通信状态检测时,使用常规检测工具难以获取有效的通信数据,无线通信接收设备无线接入点(access point,AP)发生故障时,无法及时对故障原因作出正确判断的问题,采用AD9371射频收发机与现场可编程逻辑门列阵(field programmable gate array, FPGA)相结合的方式,研究并设计了一款用于检测AP故障的设备,对无线跳频通信信号进行抓取。通过本设备获取无线通信的数据,将收集到的数据进行分析整理,实现对AP设备状态信息的实时获取。实验数据表明,该设备适用于工作频段为ISM频段任意频点的无线跳频通信系统检测。

AP fault detection device under wireless frequency hopping communication system

In the case of performing communication state detection on the wireless frequency hopping communication system, it is difficult to obtain effective communication data by using a conventional detection tool, and when the wireless communication receiving device AP fails,it is unable to make a correct judgment on the cause of the failure in time. The AD9371 RF transceiver and FPGA are combined to study and design a device for detecting AP faults,and it can capture wireless frequency hopping communication signals. The data of the wireless communication is obtained by the device, and the collected data is analyzed and organized to realize real-time acquisition of the state information of the AP device.The experimental data shows that he device is suitable for wireless frequency hopping communication system detection with an operating frequency band of any frequency point in the ISM band.
