8km long distance wireless communication module oilfield tunnel wireless transmission scheme
1. On-site demand
According to the actual requirements of the field, it is necessary to control the key parts of the oil field. Due to environmental factors not suitable for wired layout, need to transmit video signal and command control signal. In order to achieve the purpose of monitoring, we use 8km long distance wireless communication module transmission, which can not only achieve on-site functions, but also encrypt the transmission process to meet certain confidentiality requirements. And the convenience of construction and installation is more suitable.
2. On-site description
The site is located in a large oil field production site, and the oil field equipment works 24 hours a day. In order to ensure the smooth progress of mining and the safety of oil storage tank and equipment, the video surveillance scheme is used for 24 hours surveillance video. There are 10 oil Wells on site. One well group will be tested first, and 10 oil Wells will be transferred to 4 well groups first, with a distance of up to 5000 meters. The image transmission distance of 532 meters from the four drilling teams into the network, enabling the project to be viewed in real time and to deal with emergencies in a timely manner. Considering the long transmission distance, we adopt 8km long distance wireless communication module for remote wireless transmission, wireless transmission of high-definition video pictures.
3. Specific requirements of customers for wireless video transmission
With the construction of oil field automation information system, the transition from the previous extensive management to information management in the oil field has gradually strengthened the centralized management from oil production to oil transmission process, requiring the establishment of multi-system monitoring platforms, including remote video monitoring of oil Wells, distribution line automation system, oil pipeline leakage monitoring, automatic monitoring of gathering and transportation stations. The purpose is to use the field 8km long distance wireless communication module monitoring system to realize automatic data source collection, with the help of the existing network resources in the oil field to automatically load to the real-time database at the factory level, to provide an open data platform for the application of management departments at all levels, so that the production management personnel can timely control and grasp the production dynamics, to realize the automation of the entire production process. Real-time data can be counted, analyzed and optimized, which provides an important basis for ensuring the normal operation of production equipment and reducing production costs.
4. Design ideas of wireless transmission solutions
It is not convenient to integrate the 10 billiard machines on site, so 10 cameras are transmitted by 10 8km long distance wireless communication modules; well group 4 uses two omnidirectional antennas to receive and transmit a pair of 5; well group uses a switch to integrate two images of the well group, and uses one to transmit and the oil production team uses one to receive the network. Customers can monitor and record video in the monitoring center, watch the high-definition pictures of the front segment in real time, and contact the staff on duty of the front segment through two-way communication.
8km long distance wireless communication module tunnel wireless video monitoring application, wireless video monitoring can bring intuitive and convenient visual effects to the construction unit or organization. It is widely used in various occasions, such as warehouse monitoring, important traffic road monitoring and other important places such as forestry, water conservancy, oil field, tunnel, coal mine, border defense and other wireless video monitoring. You can sit in your office and see live images of important events in your organization. You can also handle various on-site emergencies, monitor the entire process, and see the effect of the on-site images after processing.
First, wireless video surveillance technology introduction
Based on digital signal and analog signal processing, wireless video monitoring realizes signal exchange, control, video storage and on-demand playback through the microwave transmission of 8km long distance wireless communication module. Through the establishment of a powerful central business platform, it realizes the unified management and centralized control of all decoding devices and video storage devices in the system. Users can call, browse, and use monitoring resources on the whole network in a unified manner by logging in to the central service platform.
Ii. Customer on-site analysis
One tunnel required a five-point surveillance system, using network HD cameras. The monitoring center is 10 kilometers away from the mining area, and 5 monitoring signals are required to be transmitted at the same time. 5 monitoring states can be switched at will in the monitoring center. The monitoring point cannot be visualized to the monitoring center, so it needs to be transferred, and the back end enters the NVR for storage.
Three, wireless transmission solutions
The three HD balls at the front end are connected with three wireless transmission devices to transmit to the relay point, receive with the wireless transmission device and enter the switch. A HD ball machine is connected to the switch at the relay point, and a HD ball machine is connected to the switch. The 8km long distance wireless communication module is transmitted, and the monitoring center uses a receiver to enter the NVR.
Four, concluding remarks
With the mobile wireless video surveillance market gradually towards individual users, wireless video surveillance will be more and more perfect, the market demand is the driving force of product and technology development.
