Therefore, due to the involvement of flammable, explosive, and toxic substances in their production processes, cybersecurity is crucial for chlor-alkali enterprises. Given the current trend towards intelligent systems, it is imperative to consider how to securely transmit internal data to Ethernet at low cost without altering existing communication software and programs, while simultaneously protecting the internal production control areas from external network traffic and isolating unauthorized access.

[0035] This utility model embodiment provides a data transmission device for the electrolysis boundary area of ​​a chlor-alkali enterprise, comprising:

This achieves data transmission in the chlor-alkali enterprise in a low-cost manner while ensuring the security of the chlor-alkali enterprise's production control area.

It is responsible for converting alternating current (AC) to direct current (DC) for use in the electrolysis process, as the electrolytic cell requires a stable DC power supply to drive the electrolytic reaction.

[0053] The chlor-alkali enterprise office area includes: a one-way physical isolator 11, a first database server 12, and a second switch 13; the DCS device 8 is wirelessly connected to the first database server 12 in the Ethernet via a third switch 9 and the one-way physical isolator 11.

[0054] Specifically, in this embodiment, a one-way physical isolator 11 is installed in the office area of ​​the chlor-alkali enterprise according to the actual working conditions of the chlor-alkali enterprise. This one-way physical isolator 11, also known as a data diode or one-way network gateway, is a network security device used to provide one-way data transmission between two networks while preventing data transmission in the opposite direction, thus ensuring the one-wayness and security of data transmission and preventing external access. The first database server 12 is remotely wirelessly connected to the DCS device 8.

[0062] The second isolation gateway 14 and the third isolation gateway 16 are connected via a dedicated line 15, and the third isolation gateway 16 is remotely wirelessly connected to the second database server 18 via the first switch 17. Here, the dedicated line 15 is a physically independent line.

[0063] Specifically, this embodiment includes first, second, and third isolation gateways, which are physical devices used to create a physical isolation layer between the two networks. The main purpose of this isolation design is to prevent direct network connections, thereby reducing the risk of malicious access, viruses, or other forms of network attacks spreading from one network to another, thus ensuring data security during the transmission of data generated in the chlor-alkali production control area to the first and second database servers 18. It should be noted that the isolation gateways here integrate existing firewalls, achieving the final layer of isolation between the external server area and the chlor-alkali enterprise production control area.

[0064] DCS device 8 is connected to the third switch 9, the first isolation gateway 10, and the unidirectional physical isolator 11 via a wired connection. In this embodiment, the wired connection, compared to the wireless connection, ensures both the stability and security of data transmission, while also improving transmission speed. The DCS device is connected to the first database server 12 via the third switch 9, the first isolation gateway 10, and the unidirectional physical isolator 11, enabling secure and rapid transmission of field data and real-time data access for the enterprise. Simultaneously, the DCS device is also connected to the second switch 13 and the second isolation gateway 14 via the third switch 9, the first isolation gateway 10, and the unidirectional physical isolator 11.

These two database servers not only store field data but also provide users with a more convenient and faster way to view data by transmitting field data to the server area.

[0065] In one optional implementation, the DCS device 8 includes: a DCS host and multiple display components, each display component being electrically connected to the DCS host; each display component is used to display real-time data for a specified electrolytic cell area; the DCS host is wiredly connected to a third switch 9. The display components in this embodiment can be located in different physical spaces. For example, the display components can be display components for an engineer's workstation or an operator's workstation.

[0066] Specifically, when selecting display components to be used with DCS, in addition to considering their functionality, it should also be ensured that they meet the safety standards of the industry in which they are used, especially in environments involving chemical handling, such as the chlor-alkali industry in this embodiment, where explosion-proof performance is particularly important.
