The conventional meter reading method generally comprises the following steps: when the concentrator is used for reading the meter, the meter reading is carried out sequentially from one meter to another, and only one meter reading command is sent each time when one meter is read.

Referring to fig. 3, fig. 3 is a schematic flow chart of a meter reading method according to a second embodiment of the present invention. As shown in fig. 3, the meter reading method may include the following steps: step S201, a meter reading task is preset in the concentrator 1, the meter reading task comprises a meter reading command set, the meter reading command set is downloaded to the meter reading device 2, and the meter reading device 2 stores the meter reading command set to the flash memory.
In the invention, the meter reading command set comprises more than 200 meter reading commands, wherein the meter reading commands comprise a time freezing meter reading command, a day freezing meter reading command, a month freezing meter reading command and the like. Each meter reading command comprises a meter reading command number and a corresponding group of electric meter commands, and each group of electric meter commands comprises meter reading sub-commands of a plurality of electric meters; the specific form of each meter reading command is (meter reading command number x: subcommand 1, subcommand 2, \8230;, subcommand m), and the data format of the meter reading command is as follows:
the meter reading command number is x,2 bytes and 16 systems;
the meter reading command length is 2 bytes, 16-system, and is the total byte number of all the sub-command message lengths and the sub-command messages);
the subcommand has the message length of 1, 2 bytes and 16 systems;
the sub-command 2 has the message length of 2 bytes and the 16 system;
subcommand 2 message, 1-65535 bytes;
the length of the sub-command m message is 2 bytes, and the length is 16 systems;
sub-command m message, 1-65535 bytes.
In one embodiment, the meter reading tasks preset by the concentrator 1 are the same for each meter reading device 2, but as another embodiment, different meter reading commands may be generated for different meter reading devices 2 according to the serial numbers of the meters because the meters connected to the meter reading devices 2 are different, and then each meter reading device 2 only downloads the corresponding meter reading command. The type of the meter reading command may be set as needed, but the present invention is not limited thereto.
In the present invention, the meter reading command set pre-stored in the meter reading device 2 is downloaded in the concentrator 1, and as another embodiment, the meter reading command set may also be directly burned in the meter reading device 2, which is not limited in this respect.
Step S202, the concentrator 1 issues a meter reading command number x to the meter reading device 2 in a broadcasting mode, and meter reading is started.
In the invention, the communication modes of the centralized meter reading networking network comprise modes of broadcasting, multicasting, unicasting and the like, in order to improve the meter reading efficiency, a meter reading instruction is issued in a broadcasting mode, and other communication modes such as multicasting, unicasting and the like can be adopted.
Step S203, after receiving the meter reading command number x, the meter reading device 2 traverses a pre-stored meter reading command set according to the meter reading command number x, and finds out the meter reading command corresponding to the meter reading command number x.
And step S204, analyzing a group of ammeter commands in the found meter reading commands to obtain meter reading sub-commands of all the ammeters in the group of ammeter commands.
And S205, the meter reading device 2 issues the analyzed meter reading sub-commands of the electric meters to the corresponding electric meters 3, and the electric meters 3 respond after receiving the commands and upload response data to the meter reading device 2.
In the invention, in order to improve the meter reading efficiency, after each meter reading device 2 receives the meter reading command number in a broadcast or multicast mode, each meter reading device 2 synchronously executes meter reading. After the meter reading is finished, the meter reading response is uploaded to the concentrator through collision avoidance communication detection, and certainly, as other implementation modes, the meter reading response can also be sequentially issued, which is not limited by the invention.
Step S206, the meter reading device 2 stores the response data of each electric meter 3 in the meter reading response list and performs response numbering.
The meter reading response list is (response number x: sub response 1, sub response 2, \8230;, sub response m), and the specific data format is as follows:
answer number, 2 bytes, 16 system;
the response length is 2 bytes, and is 16-system, namely the length of all sub response messages and the total byte number of the sub response messages;
the sub-response has the length of 1 message, 2 bytes and 16 systems;
sub-response 1 message, 1-65535 bytes, original meter reading response protocol message, and the module does not analyze;

In the invention, in order to improve the accuracy of data acquisition, the meter reading device 2 sorts and stores the response data and uploads the sorted and stored response data to the concentrator, and as other embodiments, the meter reading device 2 can also directly upload the received response data to the concentrator 1, which is not limited in the invention.
In the invention, when the concentrator 1 sequentially issues a plurality of meter reading command numbers, the meter reading device 2 sequentially performs meter reading according to the received sequence, of course, as other embodiments, the concentrator 1 can also perform priority setting on the meter reading command numbers, and the meter reading device 2 first performs a meter reading command number task with high priority.
Based on the characteristic of meter reading instruction repeatability, the meter reading instructions are numbered to form a meter reading instruction set and are stored in the meter reading device, when the meter reading is started, the concentrator only needs to issue corresponding instruction number data, and the meter reading device only needs to issue corresponding sub-instructions to realize the meter reading, and the meter reading device has the advantages that:
1. the issued command number starts meter reading, the overall transmission data byte length of the command number is small, the message is short, the data flow of the downlink communication message command is saved, the method is applicable to places with very small broadband, and based on the advantage of less transmission bytes, the meter reading speed can be increased, and the meter reading efficiency is improved.
2. The serial number message of the meter reading command is very short, and conditions are created for selecting part of electric meters for multicast synchronous starting of meter reading by using multicast communication. In the networking meter reading, the success rate of 1-time broadcasting command meter reading can not reach 100%. Multicast communication commands may be used in which more meter addresses are loaded. (at most 32 meters can be loaded at present), and a plurality of electric meters which are failed to meter are started at the same time until all the electric meters are successfully read.
3. The meter reading command set is stored in the meter reading device in advance, so that synchronous starting of the electric meters with different protocols can be realized. In the networking meter reading, the electric meters with various protocols on the site generally need to be read (for example, the user site has 645 protocols, 66 protocols, 62056-21 protocols, DLMs protocols and other various electric meter protocols). Different meter reading command sets are stored in the communication modules of the respective electric meters in advance by the same command number. Therefore, 1 meter reading command number is used for synchronously starting the meter reading of different protocol electric meters.
4. The meter reading command set is stored in the module in advance, so that different types of electric meters can be synchronously started to read different data. In the networking meter reading, electric meters with various protocol models (such as single/three-phase meters and single/multiple tariff meters) need to be read on site, and even if the same protocol is adopted, the data needing to be read are different. Different types of electric meters and different data reading commands are stored in the module memory in advance, so that the concentrator can synchronously read different data items of different types of meters.
