Software Design Of Cross-platform B/S Mode For Wireless Logic Analyzer

With the progress of science and technology, wireless technology has developed rapidly and been widely used. There are several advantages of wireless logic analyzer, such as flexible trigger, multi-channel data acquisition, strong signal detection and analysis. Besides, it is equipped with convenience, mobility, low cost and so on. In order to satisfy the test needs of users, the design of a wireless logic analyzer has been chosen as the subject.The software of wireless logic analyzer researched on this thesis is B/S mode and cross-platformed. It reduces user’s work because the software’s maintenance and upgrade are in the instrument.The software also easy to operate.In this thesis, the software design of the wireless logic analyzer is based on the research and development of wireless logic analyzer project of laboratory. First, discuss the development of the wireless logic analyzer both foreign and domestic. Then according to the functions of wireless logic analyzer, introduce the overall scheme of the software design, include the design of web page software and instrument driver. At the end of this thesis, function tests have been accomplished. The main contents of the research are as follows:1. The design and realization of the web page software. The logic analyzer entire pages are designed by HTML5 + JavaScript + CSS technology. The web software includes visit pages and control page, so that the users can have an access to the logic analyzer, and observe the data.2. The design and realization of Websocket communication. Data transmission of wireless logic analyzer uses HTML5 Websocket communication technology Websocket communication of HTML5 is different from the ordinary socket communication. According to the data transmission requirement of the research, Websocket communication has been designed to meet the requirements. The Websocket handshake protocol, the received data frame analysis, and the sent data which meet the specification have been designed in the server.3. The design and realization of driver interface functions. Its design refers to driver structure of LXI instruments available in market. In accordance with work mechanism of logic analyzer, it is designed to several parts, includes instrument initialization and close interface functions, instrument configuration interface functions, instrument trigger interface functions, acquiring data interface functions etc.The software design of wireless logic analyzer is done in the subject. After finishing the software design, the relevant functions of the software involved were tested and all the functions achieved to the design goals.
