10km wifi remote picture transmission control module Maritime exercise/construction site wireless communication guarantee case. Maritime search and rescue refers to the search and rescue work carried out by the state or department for maritime accidents. Compared with land search and rescue, maritime search and rescue is more unpredictable, difficult and costly, and requires close cooperation among all units. To improve maritime emergency response capabilities, identify deficiencies, and improve emergency management, maritime search and rescue exercises have been carried out.
1. Project requirements
Within five nautical miles, there was one command ship and six sub-ships. The cameras used on every ship are broadcast cameras. The field command ship needs to communicate with each sub-ship in real time, understand the field situation through voice and video, and give accurate instructions; The key video of analysis is transmitted to the command center of the Maritime Bureau on the ground by satellite, and the communication with the ground command center is maintained in real time.
2. Scheme design
For communication products, this demand is a conventional 10km wifi remote image transmission control module AD hoc networking application scenario. However, due to the application in the sea, there will be a variety of unexpected situations, which is a great test for the environment adaptability of communication products. After discussion, we decided to use our Marine ad-hoc network 10km wifi remote image transmission control module to ensure communication for this exercise.
The product features of 10km wifi remote image transmission control module are as follows:
● No centralized network with the same frequency
● Multi-node fast and flexible networking
● Any network topology
● High data bandwidth fast movement
● Strong anti-interference
● Multi-path resistance
● Disfigurement resistance
● Good security
● All-IP networking interconnection
● Support a variety of services
Wireless transmission project of Guangdong wind power plant construction site. Video transmission devices and sensor devices should be installed in the field operation area to ensure that the service and management can know the construction progress and fan installation process in real time, and to monitor the safe construction operations on site to a certain extent.
As the site video transmission monitoring point is located in the mountainous area, the distance is relatively long, the construction site environment is complex, and it is difficult to lay the data transmitted by optical fiber. Considering the construction and maintenance cost, the transmission scheme of the project adopts the design of wireless microwave equipment, which can greatly simplify the site work and effectively save the cost. Field point exploration combined with regional digital elevation data processing, effective pre-processing and extraction of site points successfully avoided monitoring problems, and eliminated unsuitable construction of monitoring points in the project area. Selected small points of video monitoring points for local fine-tuning or deleting re-selection points, adjusted video monitoring points for video inspection of adjacent points and visual domain analysis.
In addition, considering the phase and uncertainty of the construction site, the rapid construction of the wireless monitoring site and the completion of the construction, the reuse of the monitoring site has become the main problem to be solved. Therefore, according to the comprehensive situation analysis of the site, our company provides a new professional mobile transmission system solution of 10km wifi remote image transmission control module, which not only improves the operation surface but also solves the monitoring problem and establishes a sustainable intelligent security management system for the site.
