Description
Technical Field
The invention relates to the technical field of power Internet of things, in particular to an intelligent household energy information comprehensive simplification processing method.
Background
In recent years, the ubiquitous power internet of things construction is comprehensively and rapidly developed under the advocation and the vigorous promotion of national power grid companies. The ubiquitous power internet of things is a concrete expression form and application of the ubiquitous power internet of things in the power industry, and aims to connect power users and equipment thereof, power grid enterprises and equipment thereof, power generation enterprises and equipment thereof, suppliers and equipment thereof, and people and things to generate shared data, provide services for users, power grids, power generation, suppliers and government society, take the power grids as hubs, play a role in platform and sharing, create greater opportunities for the development of all industries and more market subjects, and create value services.
For technical and business reasons, hundreds of millions of home low-voltage users still widely maintain the traditional power access and consumption mode. The field of intelligent power utilization directly oriented to low-voltage users is always a hotspot and a difficulty in smart power grid construction in recent years, but with the development and the perfection of related technologies and equipment, a home energy information service system capable of realizing comprehensive, efficient and intelligent utilization of power flow and information flow is bound to become a focus and a bright spot of ubiquitous power internet of things construction.
Compared with the traditional power utilization network, the majority of the current household intelligent power utilization system utilizes a narrow-band low-voltage power line carrier (N-PLC) technology, mainly solves the problems of information access and uploading of various terminal power utilization equipment, transmission of remote control signals and the like, and provides broadband access of the terminal power utilization equipment and network equipment on the basis of a broadband low-voltage power line carrier (B-PLC) or low-voltage optical fiber composite cable (OPLC) technology, and develops diversified services such as user bidirectional interaction and the like on the basis to obtain better experience. However, due to the limitations of thinking, technology and standard, a series of disadvantages still exist, mainly including:
1. the intelligent degree is low, and the system cost is high and causes the practicality poor. At present, relevant equipment of a household intelligent power utilization system is not yet in a unified standard, most systems pay attention to information uploading and remote control of various household appliances, the accessed data types and sampling precision are limited, terminal equipment basically does not have data processing capacity and only has simple storage and uploading, the planning and execution process of relevant power utilization strategies needs more manual intervention and intervention, and the ordinary users feel too complicated. In a few home intelligent power systems providing broadband access and intelligent interactive services, multimedia gateway devices are developed based on ARM and even x86 architectures, so that the cost is high, and the application and popularization on the user level of the large-scale home are very difficult.
2. The communication mode is single, the transmission rate is limited, and the reliability is poor. The existing household intelligent power utilization system mainly adopts one of three communication modes, namely a low-voltage Power Line Carrier (PLC), a low-voltage optical fiber composite cable (OPLC) and a wireless Wi-Fi, and the above technologies have limitations: the PLC technology has low transmission rate (basically below 1Mbit/s, often about tens of kbit/s), and the channel characteristics are obviously influenced by the environment and change rapidly; the cost of the OPLC is high, the OPLC needs to be distributed again, and the implementation is difficult; Wi-Fi has poor signal penetration capability, large module power consumption and relatively high manufacturing cost. Due to cost, most manufacturers still adopt a single communication mode, and once a signal caused by a channel or device failure is interrupted, the signal cannot be recovered, so that the system reliability is low as a whole. If two or three communication modes are adopted simultaneously, the system cost is increased linearly, and the effect improvement caused at the same time is relatively unobvious.
3. The accuracy is poor due to the fact that the positioning capability is not available and the topology cannot be identified. Limited by the technology, the existing household intelligent electric terminal equipment does not have the capabilities of space positioning and network topology discovery. Similar to a closed battlefield, a commander can only know which personnel are in the battlefield and can communicate with each personnel, but does not know the current formation arrangement, organization configuration and personnel distribution in the battlefield, can not accurately position and identify network topology, and can not be attentive when application scenes such as troubleshooting, risk analysis, equipment maintenance and the like are developed in some complex buildings, and can not support a series of advanced application requirements such as future family intelligent maintenance, robot service, remote unmanned aerial vehicle delivery and the like.
Therefore, an intelligent comprehensive simplified processing unit and a processing method for the household energy information are needed, which are used for fusing the ultra-wideband impulse radio UWB and the power line carrier PLC in the embedded comprehensive processing unit APU technology, and realizing the reliable communication, the topology dynamic reconstruction and the terminal accurate positioning of the household energy information service network.
Patent document with publication number CN 105678647 a discloses a smart household energy internet of things system for smart city system, which belongs to an internet of things system, and the system comprises: the object platform at least comprises an energy meter, and the energy meter is accessed to the Internet of things intelligent gateway; the communication platform is respectively connected with the object platform and the management platform through a network; the management platform is respectively connected with the communication platform and the service platform and at least comprises an operator server; the service platform is respectively connected with the management platform and the user platform and at least comprises an operator server; the user platform is accessed to the service platform or the management platform and at least comprises a user side; all servers, intelligent gateways of the internet of things, users and energy meters in the system of the internet of things can be connected in a one-to-one mode, a many-to-many mode and the like to transmit sensing information and control information, and different requirements of the use of the internet of things in a smart city system are met. However, the application cannot solve the problems of low intelligent degree, low transmission rate and low accuracy of the existing intelligent household energy information gateway.
The patent with the publication number of CN 104615119B discloses a household energy management system, which comprises a bidirectional metering module, an electric power cloud identification module, an energy efficiency management module, a power supply conversion module, a comprehensive fault and monitoring module, a household management module, a security monitoring module, a multi-communication module and a display module.

However, the invention has the disadvantages of single communication mode, limited transmission rate, poor reliability, no positioning capability and poor accuracy caused by incapability of identifying topology.
