Today, I will introduce a national invention authorized patent-a method and device for matching smart meters in a multi-online household billing system. The patent was applied for by Zhuhai Gree Electric Appliance Co., Ltd., and the authorization was announced on August 10, 2018.
Content descriptionThe invention relates to the technical field of smart meters, and in particular to a method and device for matching smart meters of a multi-online household charging system.
Background of the inventionThe multi-online household billing system includes air conditioning units, smart meters, and billing equipment 301. The air conditioning unit includes n multi-line unit systems, where n is an integer greater than 2. From top to bottom, there are the first multi-line unit system 1011, the second multi-line unit system 1012,..., the n-th multi-line unit system 101n. The system includes n smart meters, from top to bottom are the first smart meter 1021, the second smart meter 1022, ..., the nth smart meter 102n. And the n smart meters are all connected to the meter communication bus communication 001, and upload data to the charging device 301 through the meter communication bus 001. The n multi-line unit systems communicate with the billing device 301 through the multi-line unit system communication bus 002, so that the billing device 301 can obtain the working status of each multi-line unit system during the commissioning process, or realize the work of each multi-line unit system Way of control. In addition, the internal machine and the external machine in each multi-line unit system are communicatively connected through the internal and external machine communication bus 003. Specifically, for example, the external machine 10111 of the first multi-line unit system is communicatively connected with the first internal machine 10112,..., The nth internal machine 1011n through the internal and external machine communication bus 003.
The billing equipment needs to clarify the smart meter corresponding to each multi-line unit system when performing the statistics of the power consumption of each multi-line unit. In the traditional technology, the corresponding relationship between the smart meter and the multi-line unit system is manually determined by the staff. That is, the staff manually writes the correspondence between each multi-line unit system and the smart meter into the billing device according to the actual wiring situation, so that the billing device can count the power and expenses.
However, the workload of manual statistics and recording of the wiring situation is relatively large, and the error rate is high.
Summary of the inventionBased on this, it is necessary to determine and enter the matching relationship between the above-mentioned manual smart meter and the multi-line unit system. The workload is large and the error rate is high, and a more simple smart meter of the multi-line household billing system is provided. Matching method and device.

In order to achieve the objective of the present invention, a method for matching smart meters of a multi-online household charging system is provided. The multi-online household charging system includes at least one smart meter and at least one multi-online unit system. The system is connected to the smart meter, and the method includes the following steps: acquiring available smart meters in the multi-online household billing system; turning on a multi-line unit system that has not been matched with smart meters; Among the available smart meters, the available smart meter with the largest instantaneous power is searched as the currently running smart meter; the currently running smart meter is determined to be the matching smart meter of the multi-line unit system that is turned on this time. In one of the embodiments, each smart meter corresponds to a meter address.
The acquisition of the available smart meter in the multi-online household billing system includes the following steps: polling the meter communication bus using the preset meter address; CN 106094577 B uses the smart meter corresponding to the meter address with the reply message as the multi-online meter The available smart meter in the household billing system.
In one of the embodiments, the method further includes: when there is a multi-line unit system that has not been determined to match the smart meter in the multi-online billing system, returning to execute the opening of the multi-line unit system that has not been matched with the smart meter. The steps of the on-line unit system are completed until the smart meter matching of all the multi-online unit systems in the multi-online household billing system is completed.
In addition to the foregoing, in one of the embodiments, the method further includes the following step: shutting down the multi-line unit system that completes the matching of the smart meter. A device for matching smart meters of a multi-online household billing system based on the same inventive concept. The multi-online household billing system includes at least one smart meter and at least one multi-online unit system, and the multi-online unit system is compatible with The smart meter connection includes: an electric meter acquisition module for acquiring available smart meters in the multi-online household billing system; a unit start control module for starting a multi-online unit that has not been matched with a smart meter System; an electric meter search module, which is used to find the available smart meter with the largest instantaneous power among the available smart meters that are not matched as the currently running smart meter; the meter matching module determines that the currently running smart meter is turned on this time The matching smart meter of the multi-line unit system is described.
The beneficial effects of the present invention include: a method for matching smart meters of a multi-online household billing system provided by the present invention, which obtains the information of each meter through the meter communication bus, and compares the information in the system through the multi-online unit system communication bus. The multi-line unit system controls, and then according to the influence of the current control action on the multi-line unit system on the smart meter, the smart meter corresponding to the currently controlled multi-line unit system is determined. In this way, the smart meter matching work of a certain multi-line unit system in the multi-line household billing system is completed, and the automatic smart meter matching of all the multi-line unit systems in the online household billing system is realized through circular execution. Compared with traditional manual matching of smart meters, the smart meter matching efficiency of the method of the present invention is higher and the error rate is low. At the same time, the smart meter matching device of the multi-online household billing system also has the above advantages.
