With the development of oil fields, the construction of digital oil fields has become the core content of the informatization construction of many oil enterprises, especially the upstream oil field enterprises, and the digital oil fields themselves have become the strategic goal of the informatization construction of oil field enterprises. For downstream enterprises, the "digital petrochemical" corresponding to digital oilfield has also been widely concerned, and become a hot spot in the informatization construction of petrochemical enterprises. Digital oilfield and digital petrochemical, as the two most important aspects of digital petroleum, lead the informationization of petroleum industry in the new era. In order to reduce enterprise costs, improve enterprise management, enhance the competitiveness of enterprises in the industry, and achieve the goals of strengthening safety, process monitoring, saving human resources, and improving efficiency, the oilfield well site unattended monitoring system, as an important part of the oilfield digital construction, has been included in the new regulations.
Sinopec oilfield comprehensive development and utilization of underground salt water resources construction of a new chemical plant. The plant was built in 1990 and completed and put into operation in April 1993. Oil fields are usually located in remote areas, sparsely populated, widely distributed and in very harsh natural environments. In order to solve the above problems, the wifi module manufacturer of 10km long-distance transmission uses wireless transmission to the oil field salt well salt water plant, and designs a special set of video data wireless solar transmission scheme.
Demand analysis of wifi module for long-distance transmission of 10km:
1. The control center can monitor the high-definition video monitoring of each salt well remotely and in real time.
2. The control center can monitor the pressure instrument data of each salt well.
3, the realization of unattended inspection system, reduce labor costs.
4. Each salt well adopts scenic complementary power generation system to ensure electricity in rainy days.
5. Realize centralized management of control center and strengthen management system.
6, the late system can have a certain expansion, convenient to add points later.
Manufacturer's scheme design of wifi module for long-distance transmission of 10km:
There are 8 mining sites of salt Wells in all remote areas. Due to inconvenient wiring, all wireless bridge transmission is adopted, and the on-site power supply is powered by solar power generator. Due to the low terrain of the control center and the tall trees around it, a 30-meter-high tower has been added to the wifi module manufacturer's control center, which can be transmitted over a distance of 10 kilometers. Point 2#, which serves as a relay point and a monitoring point, also has a 30-meter-high tower on its lower terrain. Each salt well site has data from video surveillance and pressure gauges. The data of the pressure meter is converted from the RS232 interface to the RJ45 network port via the serial port server and then transmitted back to the control center via the bridge.
wifi module for long-distance transmission of 10km Points 3# and 4# transmit to a nearby roof relay point, then to the control center's tall tower, points 1#, 2# and 8# transmit directly to the control center's tall tower, points 7# transmit to point 6# and then to point 2#, and points 5# transmit directly to point 2# and then to the control center's tower. The control tower is transmitted to the control center through optical fibers.
A successful case of Guangdong Shantou Marine wireless transmission system, Shantou is one of the early opened special economic zones in China, and is also an important port city in the southeast coast and a central city in the east and east of Guangdong. Located in the east of Guangdong Province, south of the Hanjiang River Delta, north Chaozhou, west Jieyang, southeast close to the South China Sea. As one of the birthplaces of Chaoshan culture, "there are hipsters where there is sea water", there is no doubt that there is Chaoshan culture in the hipster place.
Customer demand:
In order to better detect wind data and flow at sea, and grasp accurate wind speed and wind speed information when a typhoon arrives, the land base station needs to obtain real-time data from the wind tower at sea.
Project overview analysis:
There are two spots in the field, 15 kilometers across the field. Each point has a video. The manufacturer of wifi module with 10km distance transmission transmits the signal from point to point, and the signal image is transmitted to the base station monitoring center on shore through the wind measurement tower and wireless network bridge, so as to realize the stable transmission of data.
Project solution:
Although there are fewer environmental interference factors at the site, it is difficult to transmit signals stably between devices due to the high altitude and poor signal values of -80dBm. The technical team of the manufacturer of wifi module for long-distance transmission of 10km decides to use CV5200 wireless transmission and adopt overhead equipment to achieve signal transmission. At first, Point A was located on a mountain 40 meters above sea level with equipment on a tower 30 meters above sea level, and Point B was located on a wind tower 10 meters above sea level, but the equipment could not be exchanged. When the height of the equipment at point B is 20 meters, the equipment can communicate normally. In order to increase the signal intensity, the devices at both ends are covered by 20dBi disk antennas, with a transmission bandwidth of 100m.
After the installation, debugging and follow-up tracking service of our company's technicians, the whole wireless transmission system of the wifi module manufacturer with 10km long-distance transmission runs stably, and the videos and pictures are clear without cards. Marine management is very pleased with the project.
