Temperature and humidity, irradiance is a must-test item in the photovoltaic industry, and the current collection is mostly through the U disk storage data for off-line analysis, whether the storage is successful during the period, whether it is found in time is more difficult. This article will briefly introduce a data acquisition method for remote transmission monitoring.
The solution is to use a dandelion router to build a virtual local area network, which can remotely access the WEB server inside the data collector through a computer. Because the dandelion router is embedded with peanut shells, it is easy to build a virtual LAN. The block diagram of the program is as follows:
Steps
1. Preparation: The equipment used first includes DM100 digital recording recorder, 2 dandelion routers, 1 laptop computer (one can be used for debugging), and 2 network cables. At the same time, be prepared for broadband or wireless to enable the device to access the network.
2, configuration: first dandelion networking. According to the dandelion user manual, use the network cable or WiFi to connect to the computer, then log in to Oraybox.com, set the two routes separately, and log in according to the account password on the dandelion. Name the monitor router and the test router separately, and set the test router and the ip of the data collection to the same network segment. It should be noted that most of the test-end routers choose 4G network cards for communication.
3. Intelligent networking:
(1) After the dandelion routers on the monitoring end and the test end have been normally networked and initialized, enter their respective public and English management pages, click “Bind Account†in the smart group bar, and monitor the dandelion management page of the router on the monitoring side. In the column, click "Bind Account" to bind all the routers to the same Oray account.
(2) After the binding is successful, click 'I want to network' to create a network;
(3) Add the test end router as a networking member.
4. Commissioning phase: Two computers are connected to two routers respectively, and the routers and data collection are pinged separately, and all of them can be used if they can ping each other.
5. Usage stage: Users can view the content collected by computer or mobile phone. When using the computer to view, you can connect the computer to the router through the network cable or connect to the router's WiFi, log in the number of ip pages to view the currently collected data. To view by mobile phone, you need to connect to the router of the monitoring terminal to open the mobile phone webpage for data browsing.
The scheme is based on the acquisition of signals such as temperature and humidity supported by the DM100 data acquisition instrument. Through the intelligent networking of the Dandelion router, the data is uploaded and viewed under the support of the broadband network of the 4G network card. At the same time, the DM100 data can be viewed through the webpage, which makes it more convenient for the monitoring personnel to view and detect the data.
