Problems solved by technology

On the one hand, it is necessary to install special monitoring software on remote client devices to form a monitoring platform, which makes the client devices relatively fixed, which is not conducive to the needs of users to work anytime and anywhere
On the other hand, every time the display interface of the electronic measuring device is captured, it is necessary to repeatedly establish a TCP / IP-based SCPI connection between the client device and the electronic measuring device, and establish SCPI (the abbreviation of Standard Commands for Programmable Instruments, It is a set of command transmission mechanism used to control the standard commands of programmable test and measuring instruments. It completes the network transmission of the refresh command, and the refresh program of the measuring device sends a refresh request to the internal FPGA, returns the screen data, and connects to TCP / IP After closing and other processes, the image refresh operation can be completed. Each image refresh operation must go through at least three communication connection handshakes to capture a frame of screen data, which increases the risk of network delay and is not conducive to continuous and rapid image refresh operations. The problem of low monitoring efficiency
In the third aspect, electronic measurement equipment often converts a captured frame of screen data into an image file in BMP format for transmission. Although the user can obtain a clearer display interface image, it is easy to cause a large amount of file storage data and increase the transmission time. The problem of difficult image text extraction eventually leads to poor experience

Embodiment 1

[0042]Example 1: Please refer tofigure 1 This application provides a web page grabbing interface system, which includes a client 1 and a measuring device 2, and network communication between the two is described below.

[0043]The client 1 is a networked electronic device used by the user, such as a computer, a mobile phone, a tablet computer, etc., on which a web browser 11 can run. Preferably, the web browser 11 should support HTML5 (the standard universal markup language used by the browser). For related features, Google Chrome, Firefox, IE9 and above browsers are preferred. When the web browser 11 is running on the client 1, the web browser 11 can load the second VNC application 110, where the second VNC application 110 is a client plug-in of the VNC software, which can be used by the web page when needed. The browser 11 calls or loads, or is downloaded to the local cache area and loaded into the web page when the web browser 11 accesses the server through the IP address. When the ...

Embodiment 2

[0051]Example 2: Please refer tofigure 2 This application provides a web page grabbing interface method for a web page grabbing interface system. For the web page grabbing interface system here, please refer to Embodiment 1, which will not be repeated here. The web page grabbing interface method includes steps S100-S300, Described below separately.

[0052]In step S100, the client sends a picture refresh command. In one embodiment, the client 1 loads the second VNC application 110 through the web browser 11. The second VNC application 110 creates the client according to the user's input instructions on the browser. The terminal 1 is connected to the network of the measuring device 2 and sends a picture refreshing command to the measuring device 2.

[0053]Step S200, the measuring device returns the screen data. In one embodiment, the measuring device 1 obtains the image refreshing command of the client 1 through the VNC service unit 21, and the control unit 22 extracts its current interfa...

Abstract

A web page capture interface method and system thereof, comprising: a client uses a second VNC application program to send a command to refresh a picture to a measurement device, the measurement device extracts menu data and measurement data and synthesizes screen data of the current interface, and the measurement device utilizes the first The VNC application returns the screen data, and the client receives and displays the screen data. Since the second VNC application program on the client is loaded through the webpage, the user can perform operations anytime and anywhere on any networked device, which is beneficial to office needs in different places. Moreover, the pre-installed first VNC application program enables the measuring device to have the VNC service function, which facilitates the purpose of data communication and remote monitoring through the network, is beneficial to speed up the efficiency of drawing pictures, and can effectively improve the WEB service level of the measuring device. In addition, since the measurement device returns compressed screen data packets, the data volume is small, which can shorten the network transmission time, further improve the efficiency of refreshing images, and improve the user's operating experience.
