摘　　要：为了解决传统测试仪器在针对场信号测试时布线麻烦、干扰严重;现有的存储测试系统无法监控各测点状态、数据不能及时回传等问题。提出了一种基于WiFi的无线分布式测试系统,综合运用存储测试和无线通信技术,解决了存储测试中出现的问题。系统在FPGA控制下完成数据采集存储和无线传输等功能。增加了断线重连等无线功能,保证数据传输的可靠性,并对天线进行选择。试验结果表明,系统工作稳定、数据传输可靠,能够对各测试节点进行状态监控、参数设置和数据回读等操作,具有良好的应用前景。When using wire electrical method to test the field signals,there is a problem in placing wires and elimi-nating the electronic interference introduced by the long wires. The existing storage test system can not monitor thestate of each measuring point,and the data which acquired can not be timely return etc.. A research about wirelessdistributed measurement system based on WiFi,which integrate the storage test and wireless communication tech-nology,is presented to solve those problems. Using FPGA as the main chip to control the system complete the dataacquisition and wireless transmission. Designed the wireless function such as reconnection to ensure the reliabilityof the data transmission,and select the antenna by experiment. The test results show that the system work stableand reliable in data transmission and has the ability of state monitor、parameter setting and data read,which has im-portant application values.
