Serial communication implementation on Delphi platform for tan S monitoring

JIANG Han-lin ( Shandong Chemical Planning & Design Institute, China National Chemical Construction Corporation, Ji' nan 250013 ,China)  
To realize the distributed on-line monitoring of high-voltage capacitive dielectric loss for current transformers, bushings, coupling capacitors, capacitive voltage transformers and so on, a distributed data acquisition system is established based on RS -485 bus,in which the multi-point master-slave communication mode via RS - 485 bus is adopted between the superordinate computer and the subordinate computers. The communication format and the flow chart of serial communication are illuminated. The serial communication is implemented with COMPORT of Delphi 6.0 in Windows - NT. There are four methods to enhance the reliability of data transmission: the mean value check, the maximum check, the mean square difference check and the sum redundance check. Some techniques of serial communication are presented, including isolation protection of computer port, relationship between communication speed and distance,and so on.
