All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The current electric meter information acquisition network mainly comprises three nodes, namely a multifunctional electric energy meter, an acquisition device and a master station. The line that collector and electric energy meter are linked mainly relies on the RS485 line, and collector and main website link and generally rely on wireless or ethernet mode to go on. The electric energy meter generally adopts equipment such as singlechip STM32 as the controller, and the collector has control module such as STM32, PLC usually, and has communication module. And the host computer of the main station is a man-machine interaction end and is used as an initial section for issuing instructions.

The inventor researches and discovers that the current electric energy meter data acquisition and transmission method mainly has the following problems:

1. the acquisition is carried out by adopting a PLC control module, and the space occupied by the acquisition device is too large.

2. Because the electric energy meter relates to multiple equipment manufacturers and multiple protocols, the data interaction between the collector and the electric energy meter is inconvenient.

3. Due to the fact that customization development of the analysis program is complex, updating of the acquisition script of the acquisition device is difficult.

4. Because the collector and the master station mostly communicate in two ways, the risk of the communication link is increased.

Based on the above, the electric energy meter data transmission method and device of the message queue telemetry transmission protocol provided by the embodiment of the invention collect data from the electric energy meter through the message queue telemetry transmission protocol, so as to alleviate the technical problem of difficult data interaction.

In order to facilitate understanding of the embodiment, a detailed description is first given to the electric energy meter data transmission method of the message queue telemetry transmission protocol disclosed by the embodiment of the invention, and the method is stable in communication, convenient to interact, universal and capable of being applied to scenes such as common businesses, factory parks and the like.

Fig. 1 is a flowchart of a method for transmitting data of an electric energy meter according to a message queue telemetry transmission protocol, where the method is applied to a collector.

Referring to fig. 1, the method includes:

and S102, acquiring acquisition parameters and setting an acquisition script according to the acquisition parameters, wherein the acquisition parameters comprise an acquisition object, an acquisition period, an uploading period and an uploading channel.

It should be noted that there are two ways for deploying the acquisition script: the upper computer compiles a script and then physically burns the script to the collector; or the upper computer compiles the script, issues the script in a remote mode and deploys the script into the collector. The upper computer, i.e. the master station or the remote control terminal, is generally a computer with a visual interface, which is convenient for interaction with an operator. The upper computer of the embodiment of the invention can be loaded with a Windows system and is communicated with the Internet. And issuing a set and compiled acquisition script program through the computer. If the script program is written by a high-level program language such as C language, the upper computer compiles the collection script into a collector executable language.

It can be understood that, after the acquisition parameters are read by the collector, the corresponding code functions of the acquisition script can be automatically set or modified, or the acquisition script can be manually modified by the acquisition parameters.

And step S104, configuring an information acquisition network based on the message queue telemetry transmission protocol.

And S106, acquiring the set data object in the electric energy meter according to the acquisition script.

The collector sends out a collection signal according to the script program, collects a set data object in the electric energy meter according to the collection signal, and the collector carries out communication access through an MODBUS communication protocol and receives the electric energy meter data object transmitted in an RS485 communication mode.

And step S108, preprocessing the collected data received from the electric energy meter.

And step S110, sending the preprocessed data to be sent to an upper computer.

The inventor researches and discovers that the quality of the electric energy supplied in the later stage of the electric energy meter data acquisition and transmission schedule is influenced by the acquisition period, the reporting channel, the storage mode, the use and other factors of the electric energy meter data acquisition and transmission system. Therefore, the embodiment of the invention provides an electric energy meter acquisition and transmission scheme with the characteristics of stability, high efficiency, easy interaction, safety, convenience and the like, and data is acquired from the electric energy meter through a message queue telemetering transmission protocol so as to solve the problems.

In some embodiments, step S104 further comprises the steps of:

step 1.1), setting the acquisition end and the receiving end of the information acquisition network based on the message queue telemetry transmission protocol.

The information acquisition network sets an acquisition end Publish end, a receiving end Subscribe end of a database for receiving acquired information, a target Topic and the like based on a message queue telemetry transmission MQTT protocol.

In some embodiments, step S108, comprises the steps of:

step 2.1), receiving service data sent by the electric energy meter;

step 2.2), carrying out binary analysis on the service data to obtain analysis data;

the service data is generally in a hexadecimal format, and the hexadecimal service data is decoded, in the embodiment of the invention, the hexadecimal service data is converted into binary analysis data.

And 2.3) adjusting the analyzed data into data to be sent according to the parameter type of the analyzed data, wherein the data to be sent is in a JSON format.

In some embodiments, step 2.3) further comprises the following steps, in particular:

and 2.3.1) sequencing the analyzed data according to bytes, and dividing each parameter interval data, wherein the parameter interval data is used for representing the electricity utilization service parameters.

And 2.3.2) adjusting the data of each parameter interval into data to be sent.

Illustratively, the analyzed data is divided into parameter intervals according to byte ordering and the like, and the parameter intervals comprise a plurality of parameters such as an A-phase voltage, a B-phase voltage, a C-phase voltage and an average phase voltage. In this step, the data in the byte code format is usually converted into the JSON format for distribution and transmission. And the subscriber is easy to read and write after receiving the data.

In some embodiments, step S110 may also be implemented by the following steps, specifically including:

and 3.1) sending the data to be sent to the upper computer through a wireless network according to the uploading period.

In some embodiments, the method further comprises:

and 4.1) acquiring the acquisition script from the data transmission server through the data transmission unit and updating.

The collector is connected with each electric energy meter in an RS485 master-slave connection mode by adopting a data transmission unit DTU. The DTU can effectively reduce the volume of the collector, and is convenient and fast to install. And the DTU performs script configuration and updating through the DTU server. The DTU server is connected with the main station through a network and receives script information and the like.

In some embodiments, the above method may also be implemented by steps comprising:

and 5.1) setting a message queue to telemeter the database subscribed by the transmission server to receive messages so as to receive the target subscription information sent by the database.

In the actual application process, as shown in fig. 2, the remote control end configures the acquisition script as an upper computer, sends the configured acquisition script to the data transmission DTU server through the network, the data transmission DTU server sends the configured acquisition script to the data transmission module DTU of the collector, the collector sets based on the parameters in the acquisition script, configures the network, and acquires a large number of data objects acquired by the electric energy meter according to the acquisition script. The electric energy meter can send the data object to a data transmission module DTU of the collector through an RS485 protocol. The collector analyzes and preprocesses the data object, generates data to be sent and sends the data to the remote control end through a release or wireless network such as a 4G network. In some embodiments, the collector is further configured to send subscription information to the database server according to the message queue telemetry transport protocol server, perform setting so as to receive target subscription information sent by the database server, and the remote control terminal calls the target subscription information from the collector.

The electric energy meter data acquisition and transmission scheme based on the MQTT protocol has the following benefits:
