A method of real-time data processing which combining rejecting the mistake error,digital filtering and nonlinear fitting is presented,the photoelectric converter adopting TMS320C6711 is designed,the software flowchart is given also.
On the basis of data fusion arithmetic of single sensor and applying superior C8051F140 MCU,a data processing method of on-line fault detecting for transformer taking the data fusion technology of single sensor based on cancelling of mistake error is put forward. At the same time,CAN-BUS is applied in field data transmission.
This paper presented a method to reject and to calculate the mistake error of remote monitoring and management system for the transformer /low-voltage users, and designed a remote monitoring and management system based on the method. The paper also discussed the characteristics and the principle of CAN, hardware structure , software flow, and software anti-jamming of the system.
It is important to modern management of the power system to automatically measure and intelligently process power parameter. The method to reject and calculate the mistake error of the transformer /low voltage user remote monitoring and the principle of data mining were present.
： It is important that the pipe is through－going status，but it is difficult to measure accurately because reality condition are complicated．The paper introduces the design methods to set up datum value，and decides the mistake error，and deters the interference for improving accuracy．
The causes of the error of OCS -XY Weigher is analyzed. Based on the original weigher the system error, random error and careless error are corrected with the hardware and software technolo gies of microprocessor. Thus the measuring accuracy and reliability are enhanced.
Discussed the process control system of heat-treatment. It proposed MCU technique to solve the nonlinear remain error caused by traditional thermocouple linear, and overcomed the careless error caused by circumstance interference by using A/D converter composed by V/F converter, and rectified observation error during the measure process, and also realized the precise measure of temperature and carbon-situation.
The distributing chart is used for wiping off the careless error and the fusion method based on meaning value and recursive filtering algorithm is used to filter the collected data by the mul- ti- sensor.
