Web Server Interface for Water Purification Remote Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water purification systems face limitations in distance, data throughput, software compatibility, and printer compatibility due to reliance on RS232 serial links and specific software applications, which restricts their integration and supervision capabilities.
Innovation Solution
Implementing a web-based interface using HTTP for communication, allowing remote access and control through standard web browsers, enabling flexible data exchange and format adaptation without system updates, and facilitating integration with other systems like LIMS and OEM environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RS232 serial link is used for communication, then the system can print data to ASCII/RS232 compatible printers and download data to computers with specific software, but the maximum distance is limited to approximately ten meters and data throughput is limited to approximately 10 Kbytes/second
Solution Approach 1:
The patent introduces a web server as an intermediary component that receives data from the water purification system via RS232 serial link and republishes it through HTTP protocol. This mediator enables long-distance communication by converting the limited RS232 data stream into web-friendly formats that can be accessed remotely through standard web browsers, thus resolving the contradiction between maintaining simple serial communication and achieving extended communication distance.
2Productivity
If RS232 serial link and specific software application are used, then data can be exchanged between water purification system and computer, but the data throughput is limited to approximately 10 Kbytes/second
Solution Approach 1:
The patent implements a web server that serves multiple functions: it receives data from the water purification system, stores it in a database, generates web pages for display, and enables access through any standard web browser. This universal approach replaces the need for multiple specific software applications for different operating systems and languages, while simultaneously increasing data throughput by leveraging the higher bandwidth of web protocols compared to RS232.
3Adaptability or versatility
If specific software application is developed for each operating system and language, then the water purification system can communicate with computers, but the system complexity increases and maintenance becomes difficult
Solution Approach 1:
The patent replaces the mechanical approach of developing separate software applications for each operating system with a web-based information system that uses standardized HTTP protocols and HTML pages. This substitution eliminates the need for multiple native applications, as any computer with a web browser can access the water purification system data, thereby maintaining universal compatibility while dramatically reducing system complexity.
4Ease of operation
If ASCII/RS232 protocol printer is used, then the water purification system can print data, but the type of printer is limited and this type of printer is becoming obsolete
Solution Approach 1:
The patent changes the communication parameter from RS232 serial protocol to HTTP web protocol for printing functionality. The web server generates HTML pages that can be viewed on any device with a web browser, and printing is achieved through the browser's built-in print capability or by sending to any printer that the browser can access, thus eliminating the limitation to ASCII/RS232 compatible printers and enabling compatibility with modern printing systems.
Data Source
AI summary
A verification and control method for at least one water purification system is described, which includes a step of supplying, by a server embedded with the water purification system, an editing interface comprising a zone for selecting items of exploitation information representing physical quantities associated with the water purification system, a step of selecting, via the first remote browser, at least one item of exploitation information to constitute at least one exploitation interface page, a step of sending a request to access the exploitation page, by a second remote browser, to the server, a step of collecting the value of each physical quantity represented by a selected item of information to constitute the page, and a step of supplying, by the server, the page comprising each collected value.
