Realization of Remote Data Acquisition Based on C / S Structure in LabVIEW
Introduce the method and characteristics of using Remote Panels technology, RDA technology, TCP technology and DataSocket technology to realize remote data acquisition (Remote DAQ) based on C / S structure in LabVIEW environment. Application provides a solution.
Keywords: remote data acquisition; Remote Panels; RDA; TCP; DataSock et; LabVIEW; virtual instrument?
Before the client uses Remote Panels, you must first run LabVIEW on the Server computer, and use the LabVIEW OpTIons configuration dialog box to configure the Web Server file path and network parameters, client access rights, and VIs access rights. In order to provide web browser access, you must use the Web Publish Tool to publish web pages when configuring the server.
The second step is to connect and run Remote Panels on the client computer. There are two ways to operate Remote Panels:
Method 1: Use the Connect to Remote Panels tool in the LabVIEW environment to directly operate Remote Panels.
Method 2: Use the web browser to directly operate Remote Panels in the web page. If you enter the URL of the server in the address bar of the web browser of the client, you can directly operate Remote Panels in the web page. In the local area network, the format of the URL is: http: //PcName:Port/ViName.htm; on the Internet, the format of the URL is: http: // IpAddr: Port / ViName.htm. When Remote Panels appears on the browser, you can get control of Remote Panels by right-clicking the drop-down menu. It is not necessary to install LabVIEW to operate Remote Panels with a web browser, just install a LabVIEW Run? TIme Engine. Figure 2 shows the front panel of a virtual instrument on the server opened in the IE browser.
LabVIEW Remote Panels can not only be viewed, but can also be controlled in the LabVIEW environment or on the browser. This powerful feature allows developers to easily create remote applications, allowing users to sit in front of the computer at home on weekends to easily monitor various situations in the office, laboratory or even on the production line. The disadvantage of this method is that the test data is not available on the client.
The first step is to configure the RDA server. RDA server needs to install NI-DAQ6.0 (or higher version) and DAQ equipment, set the server's IP address, such as 192.168.0.1, and its subnet mask is 255.255.255.0. Then start the Remote Device Access Server on the server. If necessary, you can set the RDA access password in the properties dialog box of the DAQ device.
The second step is to set up the client. The RDA client should install the same version of NI-DAQ as the server, otherwise the DAQ device will not be able to connect. Set the client's IP address, such as 192.168.0.2, and its subnet mask is 255.255.255.0. The setting of the RDA client is more complicated, usually follow the steps below:
â– Select "Create New" in the right-click pop-up menu of the Devices and Interfaces item in the left-side directory tree of the client's MAX (Measurement & Automation Explorer), and select RDA / Ethernet Device in the Create New window. â– Enter the server's IP address or computer name in the Select Remote Computer dialog box that appears. â– Set the device number in the System dialog box that appears. If the DAQ device on the server is set with an RDA access password, you must enter the correct password in the Password field.
At this point, the RDA device on the client is added, and the RDA device will appear in the tree on the left side of the client's MAX. From then on, the user can operate the device as if it were locally. Write DAQ software directly on the client to realize remote data collection.
You can set the DataSocket URL address of the control in the configuration dialog box of the control's DataSocket Connection properties. The address format is as follows: dstp: // servername / dataname, for example: dstp: // lht / wave. If you set the same DataSocket ConnectionURL address for two LabVIEW controls of the same type on both computers (for example, both are dstp: // lht / wave), and the connection type (Connection Type) is set to Publish and Subscribe, these two The two controls are connected by DataSocket. The values ​​of the two controls will be completely synchronized, one of the controls will change, and the other will also change the same.
Using this feature of DataSocket, you can achieve remote data collection: use server-side software to control DAQ equipment to complete data collection, put the test data into an array control, and use the same array control in the client-side software to receive through DataSocket Server These data, and then carry out relevant processing on these data through further programming. This method actually uses DataSocket's data sharing to obtain server-side data.
Compared with the third method, the fourth method does not need to specifically write a program for sending and receiving data, but requires the installation of an additional DataSocket Server software on the server and client.
