Description
Technical Field
The invention relates to low-voltage power information acquisition, in particular to a method for acquiring and fusing data of various devices based on an HPLC network.
Background
The realization of electric energy meter data operation and distribution sharing in a low-voltage electric power data acquisition platform area has certain difficulty for a long time. The power marketing concerns about data and power consumption behaviors of users, including information such as real-time power consumption data, periodic power consumption data and abnormal reporting of the power consumption of the users, and guarantees the legality of the power consumption of the users. The basic acquisition equipment at the tail end of the data is an electric energy meter. Distribution network automation is the offline and online intelligent monitoring and management of a distribution network by utilizing various technologies, so that the distribution network is always in the optimal running state of safety, reliability, high quality, economy and high efficiency. The automatic data source of distribution network is more extensive, and its source still includes terminal (TTU), intelligent circuit breaker (MCCB), commutation Switch (Phase Switch), terminal branch terminal (LTU), reactive Power compensator (SVG), fills electric Pile (Charging Pile), Distributed energy resource detection terminal (Distributed Power) and temperature and humidity sensor (TempSensor) etc. besides the electric energy meter.
The consistency of the marketing and distribution network data acquisition behaviors can effectively reduce the repeated construction of the communication network. With the popularization of local communication technologies such as HPLC carrier communication technology and multimode technology, the sharing of local communication networks has become a trend.
Disclosure of Invention
The invention provides a power acquisition and fusion method based on HPLC (high performance liquid chromatography) main and standby routes. The method aims to realize the acquisition of marketing and distribution network data through two terminals and the same HPLC network. The marketing terminal local communication module is a main route, and the distribution network terminal local communication module is an auxiliary route; and the two routes are linked through a power line.
In the present invention, the main route of the marketing terminal device is responsible for the HPLC network setup and maintenance, in which the marketing and distribution network slave nodes are not specifically distinguished. The standby route of the distribution network terminal has no networking capability and is used as a special device to establish an S link relation with the main route of the marketing terminal based on HPLC; the marketing application acquisition service maintains the original acquisition mode. The distribution network service is forwarded to the main route through the S link, and the data acquisition result is forwarded to the auxiliary route through the S link.
One, S link establishment
S link realizes communication between main and auxiliary routes based on HPLC; and S link is established by the auxiliary route, and the terminal host of the distribution network terminal equipment is triggered. The S-link working steps are as follows:
(1) the distribution network terminal host sends a command to assist the route to enter a route interception mode;
(2) the distribution network terminal host sends a command to inquire the current carrier network information; acquiring by monitoring a network-bound beacon;
(3) and the distribution network terminal host sends a command to select a reading network and sets target network information. Entering an S link state;
(4) the distribution network terminal sends and receives PLC carrier messages in a link state;
(5) the distribution network terminal host sends a command to assist the route to exit the route reading mode;
second, S link MAC layer message
In the S link state, the carrier MAC packet needs to follow the following procedure in order to identify:
(1) sending a long MAC frame which adopts local broadcast for transmission;
(2) SNID fills in 0;
(3) the source TEI is 0 xFFE;
(4) the target TEI is 0 xFFF;
(5) the original source MAC address is a standby routing address;
(6) the destination MAC address is the MAC address of the slave node.
Third, marketing collection service
The marketing collection service is based on local communication protocol and HPLC. In principle, the marketing acquisition service and the distribution network acquisition service do not affect each other in terms of application.
Fourth, distribution network acquisition service
The following services are directly responded by the auxiliary route without forwarding the main route, and the functions comprise initialization, data query, file transmission and the like. The service forwarded to the main route through the S link includes: data forwarding, link interface detection, route query, route setting, route control, route data forwarding, route data reading, route concurrent meter reading and the like. Actively reporting the class service, and determining whether to forward the class service to a standby route or a terminal host by a main route according to the affiliation of the reported slave nodes; for the main route, marketing slave nodes and distribution network slave nodes need to be distinguished, and two slave nodes can be distinguished through two modes of archive addition and autonomous reporting of the slave nodes.
Compared with the prior art, the invention has the advantages that:
the existing marketing and distribution network data acquisition are usually carried out independently, and independent local networks are respectively built. For the HPLC communication scheme, two independent networks need TDMA timeslot coordination; at most, only 6 HPLC onnets were allowed. Too many temporary networks can lead to network communication delay promotion, influence data acquisition effect.
The invention completes communication interconnection between terminal devices based on HPLC through S link. The power line data acquisition and fusion method based on the main and auxiliary routes is realized. Fundamentally, the scheme is a single HPLC network, and the number of adjacent HPLC networks cannot be increased. The primary and secondary routes communicate via the S-link, also in CSMA slots. The scheme is simple to install, new hardware does not need to be developed, and two kinds of data can be acquired through software upgrading; in addition, the link is simple and the deployment is convenient; has stronger operability.
