Abstract
In response to the problems of large communication data volume, few communication methods and high communication costs in current electric energy information collection systems, the paper designs an electric energy information collection system based on uC/OS embedded real-time operating system. The system collects the data in the electricity meter downlink according to the parameters set by the host computer. After the data is compressed by the data collection terminal, it is transmitted to the main station through remote communication technology, which is convenient for the staff to monitor and manage the energy data. In this paper, LZO lossless compression technology and run-length coding technology are combined to improve the data compression scheme and use the RSA encryption algorithm to encrypt and calculate the data and use the touch-type fully intelligent combination interference generator PRM61245B to conduct EMC testing on the power information collection terminal. The experimental results show that the power system data acquisition system proposed in this paper can effectively improve the data transmission rate while ensuring data security, and can operate stably under the influence of external interference factors. Through a series of experimental tests, the practicability and effectiveness of the system are verified.
