Method for automatically allocating ammeter addresses

Abstract

The invention discloses a method for automatically allocating ammeter addresses. The method is used for realizing automatic address allocation of a plurality of ammeters, and comprises the following steps that: S1: an upper computer sends a broadcast setting instruction to the plurality of ammeters, so that the plurality of ammeters temporarily create a batch of ammeter address lists, and the upper computer sequentially detects the uniqueness of the ammeter addresses in the ammeter address lists; S2, the plurality of ammeters are connected in sequence, and the upper computer selects a batch ofdistributed ammeter addresses from an address pool to set the ammeter addresses; and S3, the upper computer deletes allocated address codes in the address pool and then executes the step S1 until allthe ammeter addresses in the address pool are allocated one by one. According to the method for automatically allocating ammeter addresses, the mode that the addresses are automatically allocated tothe multiple ammeters can be achieved, when the ammeters apply for the addresses to the upper computer, one address is selected from the specified address pool to serve as the communication address ofthe ammeters, optimal allocation of resources is achieved, and resource waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric meter measurement, and in particular relates to a method for automatically assigning an electric meter address. Background technique [0002] When the existing electric meters leave the factory, the addresses of the electric meters are fixed to the same address. In the installation site, the customer needs to preset an address code before installing the electric meter, and then install it in each user site, which is cumbersome to operate. Now, the function of automatic meter address allocation is carried out through a unique algorithm, which is similar to a router to assign an IP address to each Internet terminal device. Automatically assign an address code to each meter, etc. Most similar products on the market require separate address settings. , or using the serial number of the electric meter, for example, setting the address separately brings great inconvenience to the construction party, th...

[0002] When the existing electric meter leaves the factory, the address of the electric meter is fixed at the same address. At the installation site, the customer needs to preset an address code for the electric meter before installation, and then it can be installed at each user site. The operation is cumbersome.

Now through the unique algorithm to automatically assign the address of the meter, it is similar to a router to assign an IP address to each Internet terminal device, automatically assigning an address code to each meter, etc. Most similar products on the market need to be set individually. , or use the serial number of the meter, etc., such as setting the address separately, which brings great inconvenience to the construction party. The installation of a large number of meters takes a lot of time and is prone to errors. Some use the serial number of the meter as the The unique identification code of the electric meter. This kind of electric meter address is very long and inconvenient to remember. It usually needs to be represented by 4 bytes. It does not conform to the conventional communication protocol and is not convenient for the integration of various systems. The serial number cannot be modified. If the user needs to change the table, the new serial number needs to be changed in the system, which is cumbersome and does not have the convenience of using a configurable address. Using the scheme of automatically assigning address codes proposed in this paper can improve the simplicity of construction and avoid manual setting. chance of error
