The wifi module oilfield wireless transmission/unmanned vehicle remote transmission scheme, according to the specific requirements of the site, must be laid out in the key positions of the oilfield, because the environmental elements are not suitable for the wired layout, video signals and command control signals must be transmitted, so that For the purpose of monitoring, the wifi module is used for transmission, which can not only complete the on-site function, but also encrypt the entire transmission process, so as to achieve certain confidentiality regulations. And it is more suitable for the convenience of construction and setting.
The site is located at a large oilfield mining site. Oilfield equipment works 24 hours a day. In order to ensure the smooth progress of mining and the safety of oil storage tanks and equipment, a 24-hour monitoring and video surveillance program is adopted.
There are 10 oil wells on site. One well group was piloted first, and 10 wells were first transferred to the No. 4 well group, the longer one being 1,000 meters. From the No. 4 well group, the oil group with an image transmission distance of 532 meters enters the network so that the project department can view it in real time and handle it in time in an emergency. Considering the long transmission distance, go to the wireless video transmission equipment for long-distance wireless transmission, and wirelessly transmit the high-definition video screen.
With the construction of oilfield automation information system, the transition from extensive management to information management in oilfields requires the establishment of multi-system monitoring platforms such as oil well wifi module remote video monitoring, distribution line automation system, oil pipeline leakage monitoring, and input warehouse automatic monitoring. Gradually strengthen the centralized management of the process from oil extraction to oil transportation.
Its purpose is to use the site monitoring system to complete the automatic collection of data sources, automatically load the plant-level real-time database with the existing network resources of the oil field, and provide an open data platform for the application of management departments at all levels. Master the production dynamics, and then complete the automation of the entire production process; and can carry out statistical analysis and improvement on the obtained real-time data, thereby providing a key basis for ensuring the normal operation of production equipment and reducing production costs.
Design ideas, wifi module wireless transmission solution. In the field, 10 dome cameras are not easy to integrate, so 10 cameras are transmitted by 10 STs, and two STNs plus the comprehensive receiving antenna of the No. 4 well group are used for one-to-five transmission. In the well group, a switch is used to integrate the two images of the well group, one ST transmits and one ST5 is used for entering the network. Customers can monitor and record in the monitoring center, watch the high-definition pictures in front of them in real time, and contact the on-duty staff in front of them in two ways.
The wifi module of the application solution is a remote wireless control system for unmanned vehicles. With the unmanned vehicle project jointly developed by a university, sending control commands to the unmanned vehicle through the front-end wireless device, solving the video, data transmission, image and data transmission of the unmanned vehicle and the control center, to the unmanned vehicle The car sends control commands.

WiFi module introduction scheme:
The driverless car project, led by a university, uses a wifi module to wirelessly transmit devices to enable remote data and video transmission. The transmission part consists of two parts: the graphics transmission part and the data transmission part. Using the company's high-power wireless transmission equipment and advanced OFDM modulation and demodulation technology, it can support video transmission and data bidirectional transmission. In the visual environment, the transmission distance can reach 10 kilometers.
