in view of the traditional electric power communication transmission parameter remote detection system detection problem of low level and safety, put forward the new electric power remote communication parameters and to optimize the design of the detection system. First of all, the needs of users are analyzed comprehensively, and the design task of the system and the functions that need to be realized are clarified. Then, the design of remote detection system for transmission parameters is realized. The signal control circuit is used to realize the signal amplification and filtering of smart grid and optimize the input terminal of the acquisition circuit. The acquisition circuit is used to separate the power communication signals in the signal control circuit and optimize the performance of the signal transmission. The transmission parameters are transmitted by RS serial port to the computer so that the remote optimization detection of transmission parameters can be realized. The computer network communication protocol itself is driven by events, and its performance is closely related to operating system service. Consider the various factors, the use of real-time kernel famous mu C/OS - Ⅱ, which is the core of the system scheduling and control, to supervise and control the system work. The design of hardware system is realized by the device selected in this paper, and the program is written, and the network data communication is tested, which indicates that this scheme is feasible.
