In the electric meter data acquisition system, the front-end equipment has multiple functions, such as a data reading function and a statistical data display function. Background personnel can read the data of the ammeter equipment installed at the user side through the front-end equipment so as to master the power utilization condition of the user in real time.
Generally, data generated by the electric meter is sent to the back-end server for caching, and in the prior art, the front-end device generally acquires the data in real time in the following manner.
A Websocket client is deployed for each functional page of the front-end equipment, and a Websocket server is deployed for the back-end server. And the back-end server periodically counts the data and sends the statistical data to the WebSocket client through the WebSocket server.

The front-end device is also provided with a message bus, the message bus comprises at least one channel, each channel is associated with a corresponding function page, and the back-end server 20 is provided with a WebSocket server.

The front-end device 10 includes a plurality of functional pages such as a data reading page, a statistics refreshing page, and the like. Each function page is communicated with the WebSocket client through a bus, the bus comprises a plurality of channels, and each channel is associated with one function page. For example, channel 1 is associated with a data read page and channel 2 is associated with a statistics refresh page.
When a user operates on the data reading page, the front-end device 10 generates a data reading request, the front-end device 10 determines a channel 1 as a first target channel from the multiple channels, and sends the data reading request to the WebSocket client through the channel 1. The WebSocket client sends the data reading request to the WebSocket server in the backend server 20.
The WebSocket server sends the data reading request to the back-end logic processing module, and the back-end logic processing module processes the data reading request and then sends the data reading request to the electric meter device 30 to obtain data of the electric meter device 30. The processing performed by the back-end logic processing module may be to determine an identifier of the electric meter device according to the data reading request, and send the data reading request to the electric meter device according to the identifier.

The other function pages may further include a parameter configuration page where the user can set parameters of the electric meter device 30.
Optionally, the front-end device 10 generally further has a statistical data refreshing function, that is, the real-time statistical data of the electric meter device 30 is displayed on a page that needs to be refreshed in real time. In the prior art, to implement the above statistical data refreshing function, the front-end device needs to define a timer for each page that needs to be refreshed in real time, for example, a timer is defined on the statistical data display page, and data is periodically requested from the back-end server. The back-end server returns data in real time, and the front-end equipment refreshes the data of the page according to the returned data.
However, in the above method, the real-time performance of the front-end device to refresh data depends on the refresh frequency of the timer, and if the time interval is too large, the real-time performance of data refresh is reduced. If the time interval is too small, the load on the system increases.
In addition, under the condition that the access amount of the front-end equipment is large, each front-end equipment needs to refresh data, and the conditions of repeatedly requesting data and repeatedly counting data exist, so that the load of the system is increased, and the waste of system resources is caused.
Therefore, in the data reading method provided in this embodiment, the front-end device 10 further includes a statistical data display page. The data reading method may further include the following step S140 in parallel with the steps S110 to S130.

And S1401, the WebSocket client receives timing statistical data sent by the WebSocket server in real time, wherein the timing statistical data is obtained by counting the data sent by the electric meter equipment in real time by the back-end server.
In this embodiment, the electric meter device 30 may send data to the back-end server 20 in real time, the back-end logic processing module in the back-end server 20 counts the data at set time intervals, and the counted information may include: the current electric quantity, the current day electric quantity, the accumulated electric quantity, and the like.
S1402, determining a second target channel corresponding to the statistical data display page from the at least one channel.
And S1403, the timing statistical data is sent to a statistical data display page through the second target channel, so that the statistical data display page displays the timing statistical data, and the data is refreshed.
In this embodiment, please continue to refer to fig. 4, after the WebSocket client receives the timing statistical data, determine a channel 2 as a second target channel from the multiple channels, and send the timing statistical data to the statistical data display page through the channel 2.
It should be noted that, if other function pages include a function page that needs real-time data refreshing, after receiving the timing statistical data, the WebSocket client sends the timing statistical data to the corresponding function page through the corresponding channel for refreshing.
Optionally, the number of the electric meter devices is at least one, the data reading request includes an identifier of the target electric meter device, and the target electric meter device is selected from all the electric meter devices in the data reading page by the user.
Step S120 may include the following sub-step S1201.
And S1201, sending the identifier to a back-end server through the WebSocket client, so that the WebSocket server sends the data reading request to the target electric meter device according to the identifier to obtain the data of the target electric meter device, and sends the data of the target electric meter device to the WebSocket client.
In this embodiment, the target electric meter device may be one or multiple electric meter devices, and the identifier of the electric meter device may be a unique identifier of the electric meter device. For example, if the user selects the electric meter device 1 and the electric meter device 2 in fig. 1 on the data reading page to perform data reading, the data reading request generated by the front-end device 10 includes the identifiers of the electric meter device 1 and the electric meter device 2.
