| Abstract: | The realization of hardware and software of serial communication between the electric power monitoring instrument and PC computer are illustrated in this article.The electric power monitoring instrument with RS485 interface is based on the microprocessor.Keil C language is used to program.Active control component MSComm of the VB6.0 is adopted to realize the serial communication between RS485 interface and computer in the Windows system.The method is used to communicate for the instrument and computer.The monitor and control function are realized for the electric unites.And serial debugging tool is introduced in the paper too,which is used to test the communication protocols and programs.The test results show that the communication protocols and programs can completely meet the demands of design. |
