Shenghua Ye · Journal of Tianjin University Science and Technology · 2004
The measurement flexibility and capability of anti-disturbance can be improved with a distributed measuring system. The intelligent data sampling and statistical analysis in multi-parameters or multi-spots using the system can also be implemented. A kind of distributed measuring system based on serial port communication theory and electronic micrometer is designed. It presents hardware circuits connecting electronic micrometer to 89C2051 chip computer and receiver transmitter program in the computer.Based on MSComm control-object, the programs for reading and writing serial port with Visual C++ in Windows 98 system are also given. The system can connect six electronic micrometers. Every connecting length is about 1 000 m. The measurement requirement on manufacturing place is achieved.
