Problems solved by technology
[0002] The energy meter information acquisition system currently used has disadvantages such as heavy equipment maintenance workload and low degree of automation. The most important reason is that the address self-adaptation cannot be realized inside the energy meter information acquisition system.
At present, the parameters such as the address of the electric energy meter in most electric energy meter information collection systems need to be manually input. The degree of automation and reliability is greatly reduced, especially when there are a large number of electric energy meters in the system

Embodiment Construction
[0041] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0042] figure 1 It is a flowchart of the address self-adaptive method in the energy meter information collection system. After the communication starts, the energy meter information collection system is initialized. After the initialization is completed, the collector sends an instruction to upload the address of the electric energy meter, and then the electric energy meter stores the address of the collector. Then the energy meter generates a random delay to determine whether the bus is idle. If the bus is idle, the energy meter uploads its own energy meter address. If the bus is busy, it returns to the energy meter to generate a random delay state; when the energy meter uploads its own address, the collector Store the address of the energy meter and issue the delay constant, and finally reach the end state.

The invention relates to an address self-adaption method in an electric energy meter information acquisition system. The invention is characterized in that the electric energy meter information acquisition system comprises a system main station, a concentrator, an collector and an electric energy meter; the method comprises the following steps: the electric energy meter information acquisition system is initialized; the electric energy meter information acquisition system works normally; the collector queries an electric energy meter instruction of a newly added link; the collector identifies the electric energy meter separated from the link; and the electric energy meter is separated from the link. According to the scheme provided by the invention, the workload needed by manually inputting the address of the electric energy meter and other parameters in a concentrated meter reading system is decreased by means of the address self-adaption between the collector and the electric energy meter on the link, and after the electric energy meters in the system are increased / decreased or replaced, the collector and the electric energy meters in the system can identify and adapt to each other automatically, thus the degree of automation and the reliability of the system are prominently enhanced.
Description
technical field [0001] The invention relates to a method of an information collection system, in particular to an address self-adaptation method in an electric energy meter information collection system.
