With the rapid development of production technology and information technology, the demand for efficient, fast and convenient social production is also increasing. People are anxious to be freed from complicated and monotonous manual work, to do something more meaningful, especially in the production lines of some factories, people are always a mechanically and tediously repeated work, which is a great waste of valuable. The human resources have severely hampered the rapid development of productivity. This demand for production and life has greatly promoted the development of new technologies.
On some of the company's production lines, many of the devices are not connected to each other, and even less to the company's local area network. The data of the experimental equipment are manually recorded, which is complicated and error-prone, and there is no systematic data organization method, and the difficulty of data analysis is also increased. Such work is time consuming and labor intensive, and it is not convenient for updating and retrieving information. Therefore, it is inevitable to develop a faster and more reliable data collection method.
Constant temperature and humidity test chamber http:// as the research object. The constant temperature and humidity test chamber is used to place the chip under the specified temperature and humidity environment, to see the chip's high temperature resistance, low temperature resistance, and humidity resistance. The company uses it to analyze the reliability and failure of the chip. In normal times, laboratory personnel need to continuously record the temperature information and humidity information displayed on the instrument and meter, and mark the specific time of recording the data, and take it back to the office for analysis and analysis to determine the working state of the constant temperature and humidity test chamber. trend. Such an approach is not only time consuming but also less reliable. Due to human error, it is inevitable to bring a big mistake to the analysis results. Therefore, it is necessary to study a more efficient and reliable data acquisition method. Constant temperature and humidity test chamber http: temperature and humidity sensor, temperature range: low temperature 0 ° C -70 ° C, the lowest can reach -150 ° C; high temperature 150 ° C. The humidity range is: 20-98% RH. The main communication port is the RS232 serial port. Therefore, the serial communication protocol of VC0020 can be analyzed through research. Save the communication data as a TXT text file, create a database, and read the file into the database. Then set up the site, associate the database, and realize the monitoring of the PC.
