Background
At present, the conventional electrical connection systems are basically connected by physical mechanisms, and mainly adopt the conventional plug terminals and wire harnesses. This approach has certain potential in multi-Pin connection systems, such as: the small plug-in terminal is easy to lose efficacy and has short service life when the large plug-in terminal and the small plug-in terminal are integrated, the difficult plug-in force is large when a plurality of plug-in terminals are integrated, the traditional connection electric connection system has a complex structure and is large, and the requirement on manufacturing precision is very high. In addition, in a complex electric connection system, the number of wire harnesses is large, the wire harnesses are mixed in size, the wiring of the wire harnesses of the whole system is inconvenient, the service life of the wire harnesses is prolonged, and the like.
The development of PLC power carrier has been over 20 years old, and is a technology for transmitting network signals on a power line, which is a solution for meeting the demand of internet of things. As early as 1997, the national network began to apply the low-voltage centralized meter reading technology FSK, which was about 500bps at the time, because the low-voltage communication technology is not widely used due to its susceptibility to interference. In 2010, an OFDM technology is introduced by a legal power supply and Spanish power supply to solve the interference problem, the transmission rate is about 100Kbps, and the market is withdrawn in 2012 because the application effect of the power channel condition of the developing country is not considered to be good. The IEEE P1901/HPAV1.1 technology is introduced in the market in 2010, is mainly applied to high-speed power cats, has the transmission rate of 500Mbps, but has the problems of high transmission power consumption, large signal attenuation and the like, and cannot form a commercial scale. An IEEE 1901.1 technology is introduced in 2017, a balanced compromise scheme is found among power consumption, attenuation resistance and communication rate by adopting an OFDM anti-interference function, and application technologies of various rates and various protocols are developed and formed, wherein the application technologies comprise stable and reliable high-atmosphere Internet of things application of HPLC, high-speed and large-range Internet of things application of GreenPHY, 1901.1 high-speed power line application and the like.

In fact, the electric connection system has a plurality of functions and can be replaced by a PLC power carrier technology, so that the structure of the connection system is simplified, the service life of the electric connection system is prolonged, the requirement on the manufacturing precision of the electric connection system is lowered, and the system cost is lowered.
