AI Technical Summary

Problems solved by technology

[0005] 1. The degree of intelligence is low, and the system cost is high, resulting in poor practicability

At present, there is no unified standard for the relevant equipment of the home intelligent power consumption system. Most systems still focus on the information upload and remote control of various household appliances. The type of data accessed and the sampling accuracy are limited, and the terminal equipment basically does not have data processing. capacity, just simple storage and uploading, and the planning and execution process of related power consumption strategies requires more manual intervention and intervention, which is too cumbersome for ordinary users

The few home smart power consumption systems that provide broadband access and smart interactive services, their multimedia gateway devices are mostly developed based on ARM or even x86 architecture, and the cost remains high, which also makes it very difficult to promote the application at the level of Everbright home users

[0006] 2. The communication method is single and the transmission rate is limited, resulting in poor reliability

At present, the existing home intelligent power consumption system mainly adopts one of the three communication methods of low-voltage power line carrier (PLC), low-voltage optical fiber composite cable (OPLC) and wireless Wi-Fi, and the above technologies have their limitations: PLC technology The transmission rate is low (basically below 1Mbit / s, often around tens of kbit / s), and the channel characteristics are obviously affected by the environment and change rapidly; OPLC is expensive, needs to be re-deployed, and is difficult to implement; Wi-Fi The signal penetration ability is poor, and the power consumption of the module is relatively high, and the cost is relatively high

Restricted by cost factors, most manufacturers still use a single communication method. Once the signal is interrupted due to channel or device failure, it cannot be restored, and the overall system reliability is low.

And if two or three communication methods are used at the same time, the cost of the system will rise in a straight line, and the effect improvement caused by it will be relatively insignificant

[0007] 3. Poor accuracy due to lack of positioning capability and inability to recognize topology

[0012] Both of the above two systems can support a variety of services and ports, but both have defects such as poor accuracy and reliability, and do not have spatial positioning and network topology discovery capabilities
