Daqing Oilfield Wireless Mesh Network Monitoring Solution

Recently, we learned from Daqing Oilfield that Daqing Oilfield Co., Ltd. has adopted the wireless mesh Network technology provided by Beijing adlia Technology Co., Ltd. Azalea Network, completed the establishment of a wireless video monitoring platform that can cover the entire well area. It is understood that the coverage range is more than 180 square kilometers, and the distance between the central point and the well area is 10 kilometers. Each operation team is equipped with one video surveillance channel, a total of 25 video surveillance channels.
As we all know, most of the sub-regions of petroleum are in the mountainous, swamp, desert, basin, shallow sea, and other terrain and Landform Areas with a wide geographical distribution. Therefore, the operation sites of each operation team are not fixed, change Operation wells frequently. Daqing Oilfield regards safety as a top priority and creates a self-management atmosphere for all employees with a sense of prevention, preventive measures on duty, and preventive measures on items within the factory, build a long-term security culture mechanism. To ensure the safety of workers and strengthen the contact between the information control center and operators, Daqing Oilfield Co., Ltd. plans to deploy a Video Monitoring System in the work zone.
I. Requirement Description
Based on the basic situation of the outdoor operation team, Daqing Oilfield puts forward the following requirements for Beijing adelia Technology Co., Ltd:
Achieve wireless coverage in the whole well area and provide access for Wireless Video Monitoring
Implements long-distance and high-bandwidth backhaul from the well area to the plant area, and supports high-quality video and image transmission.
Centralized management of wireless network devices
Reserved Wi-Fi-based voice and downhole data collection functions
Ii. Design Principles
Based on the operational requirements of Daqing oilfield, the overall wireless video monitoring system must be designed with good compatibility, scalability, manageability, maintainability, good openness, advancement, and security performance.

Hierarchical networking Diagram
The network structure of the project needs to be designed hierarchically, as shown in. The network is divided into three layers: central node, fixed access node, and mobile node.

Business planning
After the wireless mesh network is built, you can implement Wi-Fi-based video, Wi-Fi voice, and wireless data services.
Bandwidth Planning
Each job team needs one D1 video quality for the time being, so each job team is expected to require 8 m Application Layer bandwidth, and 25 job teams need a total of M Application Layer bandwidth.
Frequency planning
The wireless mesh network system adopts the microcell architecture. The frequency configuration is basically the same as that of the GSM system. The isolation between channels should be taken into account to avoid mutual interference between system devices.
Wireless Network Security Plan
Network security is the most important link in the network platform laying process. During wireless mesh network technology, non-broadcast SSID technology, Wired Equivalent encryption technology WEP, WPA2, 802.1x authentication technology, Mac address filtering, VPN technology and other methods for network security maintenance.

Iv. Network Management
In order to make the computer network system in the system operate normally and improve the service level of the IT system, especially to manage the distributed Client/Server environment, adelia has developed corresponding management policies and systems, implements a unified end-to-end management system. The topology scheme is as follows:

5. Wireless Network Maintenance
Adelia wireless mesh network products adopt modular design, and key components adopt master-slave Redundancy Design. The system has high reliability and stability, and meets the telecom-level technical requirements. The system is easy to maintain, with less maintenance workload.
From the above content, we can see that the wireless network Networking Solution Based on adelia wireless mesh network technology has effectively solved the wireless video monitoring problem in Daqing oilfield. Both technology, solution design, system management, and subsequent maintenance have reached the world's leading level.
