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 to figure 1 , the present application provides a web page crawling interface system, which includes a client 1 and a measuring device 2, and network communication is performed between the two, which will be described separately 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 be run. Preferably, the web browser 11 should support HTML5 (the standard universal markup language adopted by the browser). For relevant features, Google Chrome, Firefox, IE9 and above browsers are preferred. When running the web browser 11 on the client 1, the web browser 11 can load the second VNC application program 110, where the second VNC application program 110 is a client plug-in of VNC software, which can be accessed by the web page when needed. The browser 11 invokes or loads, or is downloaded to the local cache area and loaded into the webpage ...

Embodiment 2

[0051] Example 2: Please refer to figure 2 , the present application provides a webpage crawling interface method for a webpage crawling interface system, the webpage crawling interface system here can refer to Embodiment 1, which will not be repeated here, and the webpage crawling interface method includes steps S100-S300, Instructions are given below.

[0052] Step S100, the client sends a drawing command. In one embodiment, the client 1 loads the second VNC application program 110 through the web browser 11, and the second VNC application program 110 establishes the client terminal according to the user's input instruction on the browser. Terminal 1 is connected to the network of measuring device 2, and sends a refresh command to measuring device 2.

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

Abstract

The invention discloses a webpage capturing interface method for measurement equipment and a webpage capturing interface system. The method comprises the steps that a client sends a picture brush command to the measurement equipment through utilization of a second VNC (Virtual Network Computing) application; the measurement equipment extracts menu data and measurement data and synthesizes the datainto screen data of a current interface; the measurement equipment transmits back the screen data through utilization of a first VNC application; and the client receives and displays the screen data.The second VNC application on the client is loaded through a webpage, so a user can operate the second VNC application on any networked equipment whenever and wherever possible, and a remote office demand is facilitated. Through utilization of the pre-installed first VNC application, the measurement equipment has a VNC service function, so data communication and remote monitoring purposes are achieved through a network, the picture brush efficiency is improved, and a WEB service level of the measurement equipment can be effectively improved. The measurement equipment transmits back a compression package of the screen data, so the data quantity is relatively low, the network transmission duration can be reduced, the picture brush efficiency is further improved, and the operation experienceof the user is improved.
