Automatic information collection method and system based on power line carrier communication

Abstract

The invention provides an automatic information collection method and system based on power line carrier communication. The automatic information collection method includes that a master control device and a collection device connected with the master control device are powered on; after the master control device is powered on, distributed network messages are issued through power line carriers; after the collection device is powered on, information of a metering device connected with the collection device is collected, and messages on the power line carriers containing the distributed network messages are started to be monitored; the collection device sends a network access request message after monitoring any message on the power line carriers; the master control device sends a network access confirmation message after receiving the network access request message; and the collection device reports the information of the metering device collected by the collection device to the master control device after receiving the network access confirmation message. The master control device and the collection device of the system perform networking automatically, the information of the metering device is reported, networking time is saved, the use ratio of a carrier channel is improved, and manual intervention is not needed.

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
