The long-distance wifi transmission module robot oil construction platform remote wireless network communication solution, in today's world, security issues have attracted widespread attention, and the application requirements of explosive robots that need to play a role in EOD robots are also becoming more and more obvious. In order to ensure the accuracy of robot behavior and limited by the current level of technology, the vast majority of explosive robots in the world are semi-intelligent robots, that is, they need to be controlled and operated remotely. Because explosive robots usually turn on high-power interference devices at the operation site to prevent the control signal transmission of some remote-controlled explosives, which has high anti-interference ability for the communication between humans and robots, our company's long-distance wifi transmission module Frequency hopping ad hoc network equipment can solve this problem very well.
Features
1. The frequency supports 450mHz-650mHz/1.0gHz-1.5gHz, the working frequency range is wide, supports 1mHz step adjustment, the working frequency can reach hundreds, which can effectively avoid the same frequency interference, and has strong environmental adaptability;
2. The long-distance wifi transmission module equipment has a long transmission distance and high bandwidth. The effective transmission distance is not less than 1km in general urban environments, and the transmission bandwidth is not less than 20mbps, which fully meets the distance and data volume requirements of the EOD robot operation site;
3. The device has high sensitivity. In the 10mHz bandwidth mode, the sensitivity is not lower than -100dBm to achieve more stable data communication;
4. Support frequency hopping and intelligent frequency selection function. In the complex electromagnetic environment, the equipment can adapt and adjust the working frequency, effectively avoid the interference range, and ensure the normal operation of the equipment.
The remote long-distance wifi transmission module wireless ad hoc network communication transmission scheme for the offshore oil construction platform. With the development of my country's offshore oil, the offshore oil industry has achieved remarkable results, especially the four major offshore oil bases in the Bohai Sea, the East China Sea, the western South China Sea, and the eastern South China Sea. . With the development in recent years, the proportion of my country's oil production has become more and more obvious.
The ratio of the number of mobile operating vessels on the on-site offshore operation platform is 2:1. The distance between the offshore operation platform and the ship is about 6km, and the height ratio of the drilling platform to the mobile ship is about 3:1. After the decision of our staff, we use long-distance wifi transmission module remote wireless equipment and MESH self-organized network base station equipment. The main fixed links are implemented by 5.8G industrial-grade base stations. Stable transmission between platforms, MESH self-organized network equipment between the platform and the mobile operation vessel, realizes the transmission in the mobile state, connects the wireless signals between the offshore platform and the mobile operation vessel, and ensures that the operation vessel staff can real-time Communicate information with the outside world.
The system consists of three parts: the signal transmitter of the offshore operating platform, the wireless ad hoc network communication link of the long-distance wifi transmission module and the receiving coverage of the mobile operating ship. The construction work vessel is equipped with wireless ad hoc network base station equipment and terminal signal coverage equipment to provide stable real-time communication links and terminal equipment signal coverage for the construction platform. There are several workboats in the design, and construction is carried out within about 6km from the offshore platform. The distance between the platforms is 10km. The height of the offshore platform is about 3:1 of the height of the sea level and the installation height of the work boat. According to the calculation of the height of the bulge of the earth, the erection height between two points can basically meet the visibility conditions.
