A Design of Wireless and Memory Test Technology System Based on WiFi

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 the state of each measuring point,and the data which acquired can not be timely return etc.. A research about wireless distributed 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 data acquisition and wireless transmission. Designed the wireless function such as reconnection to ensure the reliability of the data transmission,and select the antenna by experiment. The test results show that the system work stable and reliable in data transmission and has the ability of state monitor、parameter setting and data read,which has im-portant application values.
