| Abstract: | 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. |
