Information automatic collection method and system based on power line carrier communication

Abstract

The present invention provides an information automatic collection system and method based on power line carrier communication. The method includes: powering on the main control device and the collection device connected to the main control device; The carrier initiates a distributed networking message; after the collection device is powered on, it collects the information of the metering device connected to it, and starts to monitor the messages on the power line carrier including the distributed networking message; the collection device is monitoring After receiving any message on the power line carrier, send a network access request message; after receiving the network access request message, the main control device sends a network access confirmation message; Report the information it collects on the metering equipment. The main control device and the acquisition device in the system provided by the present invention automatically form a network and report the information of the metering device, which saves the time for networking, improves the utilization rate of the carrier channel, and does not require manual intervention.

Description

technical field [0001] The invention relates to the field of smart grid communication, in particular to an information automatic collection method and system based on power line carrier communication. Background technique [0002] Under the situation of increasingly tense energy sources, rapid growth in electricity demand, and increasing requirements for power supply services, power companies in the United States, the European Union, South Korea, Australia and other countries have all proposed the concept of "smart grid" to realize the collection of electricity consumption information by power users. It is the foundation of services such as distribution network control and demand side management. Spain’s ENDESA Power Company adopted power line broadband carrier technology to deploy a centralized meter reading solution in the Puerto Real area of ​​Spain, covering about 100,000 users; the UK has basically realized automatic meter reading for industrial and commercial users and...

Problems solved by technology

However, the user data collection process in the electricity consumption information collection of power users still requires a lot of manual intervention, including the number of installed equipment; the matching relationship of related equipment, such as electricity data metering equipment (referred to as metering equipment) and electricity data acquisition equipment (referred to as collection equipment); for equipment replacement and change, the above information needs to be manually collected and entered into the system

[0004] This not only increases manpower input, but also has no way to guarantee timeliness and reliability.

In addition, the current power line narrowband carrier communication still has the following defects: low communication efficiency (generally 50bps~1,600bps), low channel utilization (uplink / downlink interaction of only one data packet can be completed within 5~7 seconds), vulnerable to Impact of electrical equipment and electrical load
