Embodiment 1
[0040] like figure 1 As shown, the two-dimensional code-based petrochemical device data display method of the present invention is applied to real-time database nodes including equipment in non-explosion-proof areas and explosion-proof areas. Display the request data of real-time database nodes in non-explosion-proof areas and explosion-proof areas scanned by codes,
[0041] Clients are installed on mobile phones in non-explosion-proof areas, and clients are installed on explosion-proof mobile terminals in explosion-proof areas.
[0042] The methods include:
[0043] The client monitors the user to log in to the real-time database node with a unified identity account, call the camera of the mobile phone or explosion-proof mobile terminal, and scan the QR code pasted at the designated location;
[0044] Locate the corresponding data on the WEB server according to the string returned by the QR code, and quickly call the real-time data in the real-time database according to the...
Embodiment 2
[0056] like figure 2 As shown, the flow chart display method of the petrochemical plant is as follows:
[0057] The WEB server automatically generates the QR codes of all flow charts, and pastes the QR codes at the designated positions;
[0058] The user uses a unified identity account to log in to the real-time database node of the client, and uses the camera to scan the QR code generated by the specified flow chart;
[0059] The WEB server locates the corresponding flow chart according to the string returned by the QR code, and at the same time quickly calls the real-time data in the real-time database according to the parameters in the flow chart;
[0060] In the client interface, the flow chart and real-time data corresponding to the QR code are displayed to the user.
[0061] The WEB server generates a unique QRCode for each flow chart or document in the real-time database based on the QR code, prints it out and pastes it in a location designated by the user, which is ...
Embodiment 3
[0064] like image 3 As shown, the document display method of the petrochemical plant is as follows:
[0065] Users upload specified documents under their respective organizations according to their position assignment authority, and generate a QR code of the menu tree where the document is located;
[0066] After pasting the QR code at the specified location, the user logs in to the real-time database node of the client with a unified identity account, and uses the camera to scan the QR code of the specified menu tree;
[0067] The WEB server locates the corresponding document menu tree according to the string returned by the QR code, and displays it on the client interface. The user selects and queries the required document under the menu tree.
[0068] The user adopts the document management method of the menu tree, and only pastes a two-dimensional code in the same area to query all relevant documents in the area, so as to avoid tedious query and waste of resources caused...
