Description

Concentrator separation dual-channel local communication module and networking method
Technical Field
The invention relates to the technical field of concentrator local communication modules and networking of a residential electricity consumption information remote acquisition system, in particular to a concentrator separation dual-channel local communication module and a networking method.
Background
The resident electricity consumption information remote acquisition system is developed for years, is mature in data acquisition success rate at present, enters a large-scale coverage application stage, and is developed towards the direction of reliably realizing remote cost control in the future; however, in practical application, when performing remote fee control, because the length of the communication message is significantly increased, the response time of the remote fee control is long and the success rate of the communication is significantly reduced, so that it is an urgent problem to improve the reliability of the downlink communication of the concentrator.
Currently, two technologies, namely carrier communication and micropower wireless communication, are mainly adopted for downlink communication of the concentrator; the carrier communication is interfered by noise generated by household appliances on a power grid, so that the characteristics of short communication distance (in the power grid) and obvious time interval exist, and the stability of a communication path is poor; the micropower wireless working frequency point is 470 plus 510MHz, which is easily influenced by the obstruction of buildings and weather, and has the problem of blind areas in communication paths.
The national invention patent application with the application number of CN201310513117.5 discloses a concentrator local communication module, which adopts a mode of combining carrier communication and micropower wireless communication to improve the stability of a communication channel; however, in this patent application, it is not specifically disclosed which communication bus is specifically adopted by the micro-power wireless communication unit and the carrier communication unit for signal and power transmission; according to the definition of a local wireless communication module form standard of a concentrator by a national network company, a micropower wireless communication unit and a carrier communication unit can only adopt two connecting wires for connection, and adopt two connecting wires for connection and simultaneously realize the transmission of signals and power supply, under the condition of not adopting an M-BUS communication BUS, only a time-sharing multiplexing method can be adopted, and obviously, the method can not provide enough power supply support for long message communication between the wireless communication unit and the carrier communication unit; if short message communication is adopted, the communication time of the micropower wireless communication unit and the carrier communication unit is prolonged, and the efficiency of wireless communication is reduced.
The invention patent of the state with the application number of CN201410265317.8 discloses a method for determining a time-sharing path of a concentrator dual-mode local communication module, wherein two channel testing methods in the networking process clearly indicate that' the communication in the testing process adopts an asynchronous dual-mode: firstly, sending a frame of wireless test frame, and then sending a frame of carrier test frame; by adopting the inter-communication-node testing mode of wirelessly combining the carrier and the micropower, networking testing time can be obviously prolonged, and networking efficiency is reduced; meanwhile, only one communication network is generated in an asynchronous dual-mode in the communication in the test process, so that the advantages of the original communication networks of the carrier communication and the wireless communication are weakened, and the advantages of two communication channels cannot be fully exerted to achieve the best communication effect; in the resident electricity consumption information remote acquisition system, although the field electric energy meters are installed in the same meter box, the electric energy meters are connected to different phase lines of three-phase alternating current, so that carrier communication has the condition that the electric energy meters in the same meter box cannot communicate with each other, but the advantage of cross-meter-box communication of the electric energy meters can be realized, and the resident electricity consumption information remote acquisition system has the advantages of wide communication node distribution and more nodes; the wireless communication can realize the communication of the electric energy meters in the same meter box, and communication groups can be generated by taking the meter box as a unit, so that the number of communication nodes is reduced, the networking speed and the testing speed of a communication network are increased, and the reliability and the efficiency of network communication are increased; therefore, only by completely reserving the respective communication networks of the carrier communication and the wireless communication and then combining the communication networks, solving the blind area of the wireless communication by the carrier communication and solving the reliability and the speed of the carrier communication by the wireless communication, the two communication networks can get the best communication effect by making up the best of the two communication networks; but the path determining method of the invention patent obviously cannot achieve the effect.

The networking method of the concentrator separation dual-channel local communication module as claimed in claim 4, wherein: the structure of the global communication node information matrix table is as follows: the matrix table of the number (including the concentrator separation dual-channel local communication module) n +2 of the communication nodes, the outermost peripheral number of which is the communication node address, is arranged in the same arrangement sequence from left to right and from top to bottom; the internal digits of the matrix table are communication test success rate, success times and test time data among the communication nodes; the matrix table is divided by diagonal lines from left to right, the left lower part is a wireless communication node information matrix table, and the right upper part is a carrier communication node information matrix table.
8. The networking method of the concentrator separation dual-channel local communication module as claimed in claim 7, wherein: the method for calculating the communication path of the communication node according to the global communication node information matrix table comprises the following steps: starting from a target communication node which is required to be communicated by a dual-channel local communication module separated from a concentrator, searching communication nodes which can be communicated with the dual-channel local communication module in the longitudinal direction and the transverse direction; after finding out the corresponding communication node, starting with the communication node, and searching the communication node capable of communicating with the communication node again in the longitudinal or transverse direction; the method sequentially continuously searches until the found communication node falls on the leftmost column or the upmost communication node of the global communication node information matrix table; and arranging the found communication node addresses in the order opposite to the sequence of searching the communication nodes, namely arranging the communication paths of the target communication nodes which are required to be communicated by the dual-channel local communication module separated by the concentrator.
9. The networking method of the concentrator separation dual-channel local communication module as claimed in claim 8, wherein: the communication path of each communication node obtained by calculation according to the global communication node information matrix table is multiple, and after the communication path of each communication node is calculated, only three communication paths with the highest storage communication reliability are reserved; the calculation formula of the communication reliability is as follows: k = K1 × K2 × K3 … … × kn, kn =0.8T/T + 0.2T/100; wherein: k is communication reliability, wherein kn is reliability of the nth communication node, T is testing success times, and T is testing total times.
