Description

Technical Field

[0001] The present invention relates to the field of carrier communications, and in particular to a carrier dual-mode communication module for automatic topology networking. Background Art

[0002] As energy transformation continues to deepen, the "new power system" will be the most important change in the future energy system. HPLC high-speed power line carrier achieves minute-level meter reading, which is the key to its important role in the business transformation of the new power system. The realization of minute-level meter reading requires our operation and maintenance work to be more professional and accurate, and to solve various abnormal problems in the operation and maintenance of the substation in real time.

[0003] At present, various carrier units have emerged in the market for the use of HPLC high-speed power line carriers. However, these modules can usually only perform carrier communication and relay functions, and do not form a complete topological line network for the entire substation area, which affects the refined operation and maintenance of the power line carrier. In order to facilitate the collection and operation and maintenance work, a carrier dual-mode communication module with automatic topological networking is needed. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, an object of the present invention is to provide a carrier dual-mode communication module with automatic topology networking, which can solve the inconvenience of existing collection and operation and maintenance work in the prior art.

[0005] The purpose of the present invention is achieved by adopting the following technical scheme.

[0006] A carrier dual-mode communication module for automatic topology networking comprises: a copy control unit, a wireless unit and a carrier unit.

[0007] Dual-mode communication is used to obtain power line carrier communication signals and HRF wireless communication to achieve two-way communication with smart electric energy meters.

[0008] The carrier unit connects the smart energy meter with the electricity consumption collection system and is also connected with the reading control unit to obtain information from the device.

[0009] The copy control unit is connected to the wireless unit to obtain the carrier communication signal in the network where the module is located to obtain the level information.

[0010] The wireless unit judges and sorts out the hierarchical information of the copy control unit, forms a topological network from top to bottom at different levels and sends a summary.

[0011] Furthermore, the two-way communication is to simultaneously connect the smart power meter and the wireless communication website.

[0012] Furthermore, the carrier unit level information is to determine whether other carrier signals are at the upper or lower end of the module according to the different characteristics of the uplink and downlink messages of the carrier signal, so that different carrier units are interactively networked to form carrier level information.

[0013] Furthermore, topological networking is to sort the carrier unit level information from top to bottom to form a complete topological map of the entire station area. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0016] The invention provides a carrier dual-mode communication module for automatic topology networking, comprising: a copy control unit, a wireless unit and a carrier unit.

[0017] Dual-mode communication is used to obtain power line carrier communication signals and HRF wireless communication to achieve two-way communication with smart electric energy meters.

[0018] The carrier unit connects the smart energy meter with the electricity consumption collection system and is also connected with the reading control unit to obtain information from the device.

[0019] The copy control unit is connected to the wireless unit to obtain the carrier communication signal in the network where the module is located to obtain the level information.

[0020] The wireless unit judges and sorts out the hierarchical information of the copy control unit, forms a topological network from top to bottom at different levels and sends a summary.

[0021] Furthermore, the two-way communication is to simultaneously connect the smart power meter and the wireless communication website.

[0022] Furthermore, the carrier unit level information is to determine whether other carrier signals are at the upper or lower end of the module according to the different characteristics of the uplink and downlink messages of the carrier signal, so that different carrier units are interactively networked to form carrier level information.

[0023] Furthermore, topological networking is to sort the carrier unit level information from top to bottom to form a complete topological map of the entire station area.

[0024] The process of the device is explained through a more detailed description and combined with a schematic diagram.

[0025] The power line carrier communication technology of the reading and control unit is a technology that uses existing power lines for data transmission and control. Monitors are installed on each user's meter. The monitor transmits the user's operating conditions and various data to the collector, and then the collector transmits them to the computer terminal. The reading and control unit can obtain the uplink and downlink carrier signal readings of all meters in the power line of the substation. The uplink and downlink messages are different, so as to judge whether other carrier units are in their own uplink position or downlink position. For example: the following modules a and b are located in the upper and lower levels of the power line respectively. The reading and control unit in the communication module performs long-term monitoring and reading. Read the signals of other carrier units, and then judge the distance between the signal point and itself on the power line according to the uplink and downlink carrier signal strength, packet loss rate, etc. For example, if a and b are far apart, the carrier signal strength read by each other is reduced, and the packet loss rate is serious. Then the strength of the concentrator carrier signal is obtained to determine who is close to the concentrator. In this way, a basic "carrier level information" is obtained. The carrier level information communication and transmission are aggregated through the wireless unit to completely judge the upper and lower levels of all meters in the entire area, forming a substation topology network diagram drawn with this information that includes meters in the entire area.
