[0042] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0044] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0045] In addition, if the terms "first", "second" and the like are used, they are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0046] It should be noted that, in the case of no conflict, the features in the embodiments of the present application can be combined with each other.

[0047] In the electric meter data acquisition system, the front-end device has multiple functions, such as data reading function, statistical data display function. The background personnel can read the data of the electric meter equipment installed on the user side through the front-end device, so as to master the user's power consumption in real time.

[0048] Generally, the data generated by the electric meter is sent to the back-end server in real time for caching, in the prior art, the front-end device usually realizes real-time data acquisition in the following way.

[0049] A WebSocket client is deployed for each function page of the front-end device, and a WebSocket server is also deployed on the back-end server. The back-end server regularly counts data and sends the statistical data to the WebSocket client through the WebSocket server. The WebSocket client refreshes the data on the corresponding function page according to the received statistical data.

[0050] In the above method, since a WebSocket client is needed for each function page, too many WebSocket clients are deployed, which increases the management difficulty and causes waste of system resources. Moreover, deploying a WebSocket client for each function page increases the development workload of the front-end device.

[0051] To solve the above problems, the embodiment provides a data reading method. A WebSocket client is deployed on a client. When a user requests data reading on a front-end device, the front-end device can directly send a request to a back-end server through the WebSocket client to obtain data of a power meter device, thereby improving the real-time performance of data transmission. Moreover, only one WebSocket client is deployed on each front-end device, thereby saving system resources.

[0052] Please refer to Figure 1 , Figure 1 Fig. 1 shows an application scenario of a data reading method provided by the embodiment, which includes m front-end devices, a back-end server 20 and n power meter devices. The back-end server 20 communicates with each front-end device and each power meter device.

[0053] The power meter device is installed on a user side and is used to collect power consumption data of the user.

[0054] The front-end device is deployed with a WebSocket client, and the back-end server 20 is deployed with a WebSocket server. The communication between the front-end device and the back-end server 20 is realized through the communication between the WebSocket client and the WebSocket server.

[0055] The front-end device is installed on a power grid company side. The front-end device is installed with a browser, and the browser includes multiple function pages, such as a data display page, a data reading page, a pull-in and pull-out page, a parameter device page and the like. A user can operate on each function page to realize the operation on the power meter device 30.

[0056] For the convenience of description, please refer to Figure 2 The data reading method provided by the embodiment is described by taking the communication between the back-end server 20 and the front-end device 10 and the power meter device 30 as an example. The front-end device 10 can be any one of the m front-end devices in Figure 1 The power meter device 30 can be any one of the n power meter devices in Figure 1

[0057] On the basis of the above content, the data reading method provided by the embodiment is introduced. Please refer to Figure 3 , Figure 3 Fig. 2 shows a flowchart of the data reading method provided by the embodiment, which includes the following steps S110-S130.

[0058] S110, a data reading request is generated according to a data reading operation of a user on a data reading page.

[0059] ​In the embodiment, the front-end device 10 comprises a data reading page for reading data of the electric meter device, wherein the electric meter device can be all the electric meter devices in communication with the back-end server or part of the electric meter devices, and the user can select in the data reading page.

[0060] S120, sending the data reading request to the back-end server through the WebSocket client, so that the back-end server acquires the data of the electric meter device and returns the data to the WebSocket client.

[0061] In the embodiment, the WebSocket client is pre-deployed, and the WebSocket is a network transmission protocol which can realize full-duplex communication on a single connection, so as to better save system resources and bandwidth and achieve real-time communication.

[0062] S130, the WebSocket client sends the data to the data reading page for display.

[0063] In the embodiment, the data reading page can not only display the acquired data, but also download the acquired data to the front-end device.

[0064] Compared with the prior art, the data reading method provided in the embodiment can improve the real-time performance of data transmission by deploying the WebSocket client in the front-end device, and when the user requests to read data in the front-end device, the front-end device can directly send the request to the back-end server through the WebSocket client to acquire the data of the electric meter device.

[0065] Optionally, the front-end device 10 further comprises a plurality of function pages, and the plurality of function pages comprises the data reading page. The front-end device is further deployed 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 deployed with a WebSocket server.

[0066] The step S120 can comprise the following sub-steps S1201-S1203.

[0067] S1201, determining a first target channel corresponding to the data reading page in the at least one channel.

[0068] S1202, sending the data reading request to the WebSocket client through the first target channel.

[0069] S1203, the WebSocket client sends the data reading request to the WebSocket server.

[0070] In the embodiment, please refer to Figure 4 ,Figure 4 The process of the front-end device 10 and the back-end server 20 communication is shown. The front-end device 10 includes multiple function pages such as a data reading page, a statistical data refreshing page, etc. Each function page communicates with the WebSocket client through a bus and a WebSocket client, and the bus includes multiple channels, each of which is associated with a function page. For example, channel 1 is associated with the data reading page, and channel 2 is associated with the statistical data refreshing page.

[0071] When the user operates on the data reading page, the front-end device 10 generates a data reading request, and the front-end device 10 determines channel 1 as a first target channel from the multiple channels and sends the data reading request to the WebSocket client through channel 1. The WebSocket client sends the data reading request to the WebSocket server in the back-end server 20.

[0072] 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 sends the data reading request to the electric meter device 30 to obtain the data of the electric meter device 30. The processing performed by the back-end logic processing module can be determining the identification of the electric meter device according to the data reading request and sending the data reading request to the electric meter device according to the identification.

[0073] The other function pages can include a pull-in and pull-out breaker page, and the user can perform pull-in and pull-out operations on the electric meter device 30 on the pull-in and pull-out breaker page. The other function pages can also include a parameter configuration page, and the user can set the parameters of the electric meter device 30 on the parameter configuration page.

[0074] Optionally, the front-end device 10 generally also has a statistical data refreshing function, that is, the real-time statistical data of the electric meter device 30 is displayed on the page that needs to be refreshed in real time. In the prior art, to implement the above-mentioned 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 to request data from the back-end server at a fixed time interval. The back-end server returns data in real time, and the front-end device refreshes the data of the page according to the returned data.

[0075] However, in the above method, the real-time performance of the data refreshing of the front-end device depends on the refreshing frequency of the timer. If the time interval is too large, the real-time performance of the data refreshing is reduced. If the time interval is too small, the load of the system is increased.

[0076] In addition, in the case of a large number of accesses to the front-end device, each front-end device needs to perform data refreshing, and there is a situation of repeated data requests and repeated statistical data, which increases the load of the system and causes waste of system resources.

[0077] Therefore, the data reading method provided in the embodiment further comprises a statistical data display page.

[0078] S140, displaying the statistical data of the electric meter device through the statistical data display page and performing real-time refreshing.

[0079] Optionally, the plurality of function pages comprises the statistical data display page. Step S140 can comprise the following sub-steps S1401-S1403.

[0080] S1401, the WebSocket client receives the timing statistical data sent by the WebSocket server in real time, wherein the timing statistical data is obtained by the backend server according to the data sent by the electric meter device in real time.

[0081] In the embodiment, the electric meter device 30 sends data to the backend server 20 in real time, and the backend logic processing module in the backend server 20 performs statistical processing on the data at a set time interval. The statistical information can include the current power, the daily power consumption, the cumulative power consumption, etc.

[0082] S1402, determining the second target channel corresponding to the statistical data display page from the at least one channel.

[0083] S1403, sending the timing statistical data to the statistical data display page through the second target channel, so that the statistical data display page displays the timing statistical data and refreshes the data.

[0084] In the embodiment, please continue to refer to Figure 4 After the WebSocket client receives the timing statistical data, it determines channel 2 as the second target channel from the plurality of channels, and sends the timing statistical data to the statistical data display page through channel 2.

[0085] It should be noted that if the other function pages include a function page that needs real-time data refreshing, the WebSocket client will send the timing statistical data to the corresponding function page through the corresponding channel for refreshing after receiving the timing statistical data.

[0086] Optionally, the electric meter device is at least one, and the data reading request comprises an identifier of a target electric meter device. The target electric meter device is selected by the user from all electric meter devices on the data reading page.

[0087] Step S120 can comprise the following sub-step S1201.

[0088] S1201, send the identification to the backend server through the WebSocket client, so that the WebSocket server sends a data reading request to the target electric meter device according to the identification, to obtain the data of the target electric meter device, and sends the data of the target electric meter device to the WebSocket client.

[0089] In the embodiment, the target electric meter device can be one or multiple, and the identification of the electric meter device can be a unique symbol identification of the electric meter device. For example, the user selects electric meter device 1 and electric meter device 2 in the data reading page to perform data reading, and the data reading request generated by the front-end device 10 includes the identifications of the electric meter device 1 and the electric meter device 2. Figure 1

[0090] Compared with the prior art, the embodiment has the following beneficial effects:

[0091] Firstly, the data reading method provided by the embodiment, by deploying a WebSocket client in the front-end device, when the user requests to perform data reading in the front-end device, the front-end device can directly send a request to the backend server through the WebSocket client to obtain the data of the electric meter device, thereby improving the real-time performance of data transmission.

[0092] Secondly, compared with the prior art of deploying a WebSocket client for each function page, the embodiment only deploys one WebSocket client in one front-end device and establishes a bus, and different function pages are associated by using different channels in the bus, thereby saving system resources and reducing the development work of the front-end device.

[0093] Finally, for the function page that needs real-time data refreshing, the backend server actively sends the timing statistical data to the front-end device at regular intervals, and then the corresponding channel of the WebSocket client in the front-end device sends the timing statistical data to the corresponding function page. Compared with the prior art of requesting refreshing at regular intervals by different function pages, the method in the embodiment can update the data of multiple function pages at the same time only once, thereby reducing the waste of system resources.
