Online Monitoring System of Cable Based on Microchip 51

摘要

As an industry-specific dedicated communication network, electric power communication is gradually formed and developed with the development of power systems. It is mainly used to alleviate the lack of communication capabilities caused by the slow development of the public network and to fill the public network's inability to meet the special communications of some power departments. The contradiction of demand to ensure the normal and efficient operation of specialized electric power production. Nowadays, power communication security technology is becoming more and more important, and detecting the disconnection of communication cables is the main means to ensure smooth communication. This paper proposes a distributed monitoring system to detect the disconnection of communication cables. MSP430F149 and FPGA are used to form a high-speed variable sampling rate system to detect obstacles in communication cables. DTMF dial chip MT8888 and embedded modem chip MSM7512 are used to realize remote alarm and data exchange functions. The whole system is easy to control, flexible, and expandable. The experimental results show that this article has solved the problem of online monitoring of communication cables. The sustained and rapid growth of China's economy has provided a huge market space for the development of communication cable security technology. The strong temptation of the Chinese market has made the world focus on the Chinese market. The huge production capacity formed by China's cable security technology let the world admire. With the continuous expansion of China's power industry, data communication industry, urban rail transit industry, automobile industry, shipbuilding and other industries, the demand for wires and cables will also grow rapidly. In the future, there is still huge development potential for wire and cable protection.
