Embodiment 1

[0044] see Figure 1 to Figure 3 , the present invention provides a kind of technical scheme:

[0045] An explosion-proof control cabinet includes an explosion-proof casing 1, an on-site PLC2 (Programmable Logic Controller, programmable control device), a first VPN (Virtual Private Network, virtual private network) router 3 and a single-board computer 4; A VPN router 3 is connected, and the first VPN router 3 is connected with the single board computer 4 .

[0046] The on-site PLC2, the first VPN router 3 and the single-board computer 4 are all arranged in the explosion-proof casing 1, and the explosion-proof casing 1 is provided with a plurality of levels, and the on-site PLC2, the first VPN router 3 and the single-board computer 4 are all arranged within the topmost hierarchy.

[0047] In this embodiment, the explosion-proof control cabinet is provided with three layers, and the bottom layer is provided with a ground wire row 5, a single-layer terminal 6, a multi-layer ter...

Embodiment 2

[0052] see Figure 4 , the present invention provides a kind of technical scheme:

[0053] A remote control system for an unattended point gas supply and gasification station includes a remote control terminal, an explosion-proof control cabinet and an on-site monitoring and control component;

[0054] The remote control terminal includes a remote monitoring terminal and a second VPN router; the remote monitoring terminal is in communication connection with the second VPN router.

[0055] The explosion-proof control cabinet includes a first VPN router 3, an on-site PLC2 and a single-board computer 4; the on-site PLC2 is connected with the first VPN router 3, and the first VPN router 3 is connected with the single-board computer 4; the first VPN router 3 is connected through 5G wireless The network module is connected to the Internet; the explosion-proof control cabinet and the remote monitoring terminal are networked through VPN technology, so that the remote monitoring termi...

Embodiment 3

[0063] see Figure 5 to Figure 8 , the present invention provides a kind of technical scheme:

[0064] The present embodiment also provides a remote control method for an unattended point gas supply and gasification station, which specifically includes the following steps:

[0065] First, VPN networking is performed through the first VPN router 3 and the second VPN router, so that the explosion-proof control cabinet and the remote control terminal communicate.

[0066] Synchronous timing, the on-site PLC2 performs network timing through the SNTP (Simple Network Time Protocol) protocol, so that the on-site PLC2 time is always synchronized with the network time, which can ensure the time accuracy of all messages and avoid data confusion.

[0067] At the same time, the on-site PLC2 establishes a UDP (User Datagram Protocol, User Datagram Protocol) communication client, sends a timing message to the NTP Server (Network Time Protocol Server, network time service protocol), and the...

Abstract

The invention discloses an explosion-proof control cabinet, an unattended point gas supply station remote control system and an unattended point gas supply station remote control method. By applying an intelligent 5G wireless industrial router remote networking technology, on one hand, the requirement for remote control over a remote unattended point gas supply station is met, and on the other hand, the network transmission safety, integrity and reliability of the gasification station are optimized, so that the overall performance of LNG gasification station equipment is improved, and intelligentization is achieved.

Description

technical field [0001] The invention relates to the technical field of gasification stations, in particular to an explosion-proof control cabinet, an unattended point supply gasification station remote control system and a method. Background technique [0002] LNG is widely used in the field of civil gasification. LNG is gasified from a liquid at -162°C into a gaseous natural gas through endothermic gasification, and then it is transported to thousands of households for residents to use through pressure regulation and odorization. With the implementation of the rural coal-to-gas strategy, some point-supplied gasification sites are relatively remote and the site scale is small. For small sites, wired network or dedicated line network is used for networking, the networking cost is high, and the network transmission is unstable. Data transmission is prone to errors, resulting in low remote control efficiency and security issues. SUMMARY OF THE INVENTION [0003] The purpose ...
