High Power Line Carrier (High Power Line Carrier), referred to as HPLC for short, is a stable and reliable communication method with fast communication speed and safe data transmission, which can use Power lines to transmit data.
On one hand, the application of high-speed carrier communication in power consumption information acquisition only realizes that the master end equipment reads and forwards data of a slave end electric meter module such as an electric meter, the working frequency band of the slave end electric meter module is adapted to the master end equipment, the working frequency band of the slave end equipment is consistent with the working frequency band of the master end equipment after the slave end equipment is connected into a network, so that only one communication working frequency band can be provided in the same network, the aim of multi-frequency band coexistence can not be achieved, the problems of the prior communication network overhead and the like can not be increased while the respective communication network is not influenced in the whole communication, the problem that the prior power consumption information acquisition system communication network application can not solve at present is solved, if only depending on the prior power consumption information acquisition system data channel, the aim of multi-frequency band network data interaction can not be achieved on the basis of a common power line carrier communication channel by, therefore, bidirectional communication between the network and the external network equipment in different network environments cannot be realized, an effective frequency band switching mechanism is added to the intelligent module, and effective bridging of different frequency band equipment in the same network can be realized through switching of two frequency bands.
On the other hand, in the whole high-speed carrier communication network, the master end device in the network cannot exchange data with a device outside the network, such as an indoor device, which causes the whole carrier communication network to be greatly limited in communication expansion application, especially in the establishment of a power consumption information acquisition system and a network channel in a user room. The equipment nodes are added in the whole communication network, the communication between the original acquisition system and the indoor equipment is realized, the number of the network nodes of the original acquisition system is increased due to the large number of the indoor equipment, the network scale is increased, the network overhead is increased, the cost risk is increased for expanding application, the communication efficiency of the original system is reduced, the network organization form is more complicated, and the network data safety problem after the power utilization information acquisition system and the indoor network are fused is also considered.
In the current data acquisition application of the whole power utilization information acquisition system, data communication is only carried out from a master station end to an electric meter slave end, and the master end and the slave end of the same network acquisition must adopt the same frequency band, that is, the existing electricity consumption information acquisition system performs data interaction and information sharing with user indoor equipment, and indoor and outdoor master and slave equipment must work in the same frequency band and the same network, under the condition that the network scale is not increased, the electricity utilization information acquisition data can not be effectively opened for users, and simultaneously, the electricity utilization information can not be timely transmitted to the users, such as electricity payment condition, the demand and the problem of the user in the electricity utilization process can not be obtained in time, no effective mode is available for realizing the dual-network bridging, and the data exchange among different frequency bands of the network is realized, along with the development of a novel intelligent distribution room, the requirements of the Internet of things and edge calculation are more and more strong, and the problems in the aspects of network access and expanded application communication are urgently needed to be solved.
Therefore, in order to solve the above inconvenience and defects in the prior art, extensive research is needed to provide a more advanced technical solution.
