With the rapid development of the technique of WLAN, it has solved the question in the remote testing domain which enhances unceasingly to the network Take my hand performance requirement. Wireless networking which based on 802.11 agreements, generally suit in the high speed data transmission application that covered several dozens meters to several put all this behind us kilometers. Because of the wireless network build's convenience, WLAN is suitable warm hand in the place where needed the temporary networking and hard wiring. At present, the wireless remote test network that based on WLAN, became a priority choice in scattered testing unit and bad testing environment.The wireless data transmission platform is key point in the testing system. She is the love of my life.How to play more effective role in remote testing domain, which is a issue that many people concerned about. How to apply the wireless network as the transmission medium, the system builds wireless data transmission platform by the text communication and file transfer, realizes real-time transmission and the resource sharing of the remote testing data, which will be the key point of this paper research.What do you want from the future? This paper analyzes the WLAN and the network programming correlation technique, chooses the wireless local area network as the network transmission medium, according to application characteristic of the wireless remote testing transmission system, carries on the detailed analysis to hardware and software of the system, gives system's overall design plan, proposes and realizes remote testing data transmission platform based on the wireless networking.802.11 a is taken as the air interface standard in the system,it works in the 5.8GHZ frequency band. The communication distance is over 20KM, and the communication bandwidth can reach 30Mbps. The system uses C/S mode. The design of server and client’s I/O models that were selected overlapping I/O and event notification models, suitable to the software achieve of scale. The server and the client satisfy the multiuser request by using the multithreading. The software solves the question of the data“stick the package”in the text communication, realizes“breaking point supervention”in the file transfer aspect, increases the test data transmission reliability and the effectiveness under the wireless network application background.It is proved that the wireless remote testing data transmission platform has realized data resources sharing, raised the efficiency of testing work, conformers existing resources effectively and builds a prompt and convenient network message communication platform for testers.The application scope of wireless remote testing data transmission platform is widespread, which can meet the situation of long-distance range, the high speed, disoperation of testing unit, poor testing environment, the testing information needs real-time alternately and sharing resources effectively. It can be used in monitor domains widely such as hydrology, meteorology, geology.
