Industry Overview:

With the construction of the oilfield automation information system, the internal management of the oilfield has transitioned from extensive management to information-based management, gradually strengthening the centralized management requirements for the oil production to oil transportation process. A multi system monitoring platform has been established, including remote video monitoring of oil wells, automation systems for distribution lines, leakage monitoring of oil pipelines, and automation monitoring of gathering and transportation stations and warehouses
The purpose is to use on-site monitoring systems to achieve automatic collection of data from the source, and to automatically load it into the real-time database at the factory level with the help of existing network resources in the oilfield. This provides an open data platform for application by management departments at all levels, enabling production and management personnel to control and grasp production dynamics in a timely manner, thereby achieving automation of the entire production process; And it is possible to obtain
Real time data is collected, analyzed, and optimized to provide important basis for ensuring the normal operation of production equipment and reducing production costs.

System composition:
The remote digital oilfield video wireless monitoring system consists of three parts: front-end image acquisition system (including power supply system), wireless transmission system, and back-end monitoring management command system. It is a complete set of remote digital safety comprehensive management that is specifically designed for the geographical characteristics of the oil well location and can be combined with the local geographical environment
Solution for Oilfield Wireless Monitoring System. This system meets the needs of local monitoring and multi-level networked video monitoring with central networking. It can monitor the safety situation of the oil field in real-time 24 hours a day, reducing the labor intensity of safety monitoring personnel and providing strong support for the command of the monitoring center, enabling dispatchers at all levels of monitoring centers to monitor through monitoring
The on-site images transmitted remotely provide a visual, accurate, and timely understanding of the actual situation in each work area.

Industry characteristics and equipment selection:
1. The climate environment is relatively harsh, with natural phenomena such as snow, fog, and sandstorms being common, and temperature fluctuations being significant. Therefore, an all-weather outdoor wireless bridge should be selected to build the network, in order to ensure stable operation in various harsh natural climate environments. 
2. Petrochemical enterprises are generally located in remote areas with wide coverage. The distribution of various oil production points in the oilfield production area is relatively scattered, with some oil production points several hundred meters apart and others dozens of kilometers apart. 
3. The oil extraction point is generally open to the monitoring center without any obstacles in between. However, due to the long distance, if the distance exceeds 50 kilometers, it is recommended to choose a suitable location to install relay equipment and use a point-to-point feedback link to ensure the transmission of long-distance images back to the monitoring center. 
4. The system has strong scalability. The oil extraction point may be added or removed at any time as the work progresses, so wireless equipment installation is required to be simple and flexible. 
5. The monitoring front-end consists of network cameras (or video network servers), controllable gimbals, alarm signal generators (fire, gas leakage, anti-theft, etc.), etc. It converts and compresses audio, video, alarm and other signals into data packets that can be transmitted through the network, and sends them back to the server in the monitoring center for centralized processing.

When connecting sensors and alarm linkage devices, attention should be paid to:
1) Connect the 485 control line correctly.
2) Set 485 address.
3) The control protocol for devices such as cloud mirror decoders and keyboards must be consistent.
4) The baud rate of the front-end and back-end devices should be set to be the same. 
6. The front-end monitoring camera should be equipped with an outdoor temperature control cover with wiper and dust removal function to prevent dust and oil stains from damaging the camera. The video cable of the camera should be connected to the network video server. Connect the data bus of oil pressure gauge, flow meter, etc. to the network video server, and use the transparent channel of the network video server for transmission. In system control
It can also be connected to current and voltage detection modules, temperature and humidity detection modules, which can share the data channel of the network video server. The network video server is connected to the local wireless monitoring network. 
7. Require real-time monitoring of all oil well video images 24 hours a day, with extremely high stability requirements for wireless links. Therefore, it is necessary to require the device to have high receiving sensitivity, large bandwidth, and good stability performance.
