Mesh WIFI module remote picture transmission video wireless transmission of factory, steel plant/reservoir, in order to standardize management, the steel plant to the workshop to achieve unattended or remote control operation. Determine where to install a video surveillance system to monitor the site in real time. Because of the complex environment inside the steel mill, wiring monitoring is difficult to implement, wireless transmission becomes the most suitable choice. The manufacturer was invited to provide planning and technical guidance for this project.
Customer demand
The technician communicates with the customer to understand the situation on site. Mobile communication between the master station and the slave station with 200 meters of fixed track of two steel mills, transmitting video and data. There is a metal factory door frame in the middle. There is a square gap of 2.5 meters on the fixed track, which is easy to move back and forth from the two workshops on the fixed track. The client wants to transfer data between the master server (fixed) and the slave station (mobile terminal), requiring that the transmission cannot be interrupted and that the image and data terminal transfer be smooth.
The wireless transmission scheme is introduced
The steel mill workshop has two fixed tracks, one is point to point horizontal transmission. After the planning of our technical staff, we decide to adopt the fixed track CV5200 wireless network bridge, which is independently developed and produced by the remote image transmission manufacturer. The main station adopts directional antenna, which transmits from the station with the omnidirectional antenna of the mobile terminal. There is a metal door frame in the middle of the track, and the main station adopts 19DB large-angle directional antenna to receive and transmit signals. Install the antenna vertically.
The other is a one-to-two horizontal to air transmission mode, three CV5200 all wireless networks adopt the whole antenna horizontal installation, in order to increase the transmission and receiving angles, to meet the transmission requirements.
Project effect
It was learned later that the whole wireless transmission project ran well and achieved the expected effect of customers, and the signal transmission of wireless bridge equipment was stable. Follow-up technical personnel help waterproof the interface of the device to ensure the service life of the device.
Mesh network WIFI module remote picture transmission manufacturers applied in the reservoir video monitoring project
Project background
The reservoir is cut off from the river, with a total capacity of 18.5 million cubic meters and an irrigated area of 77.4 hectares. Reservoir plays an important role in flood control and disaster reduction and water environment protection. Therefore, in order to manage the reservoir scientifically, safely and automatically, the reservoir management department needs to install a complete video surveillance system for the reservoir.
Project requirement
Due to the large reservoir area and complex terrain, it is difficult to realize manual monitoring and management. The front end monitoring point of the reservoir is far away from the monitoring center, the location is scattered, and the original environment is not damaged. The construction of traditional network wiring is inconvenient and the cost is high. The video and information are transmitted to the monitoring center using the wireless transmission technology of remote picture transmission manufacturer based on Mesh network WIFI module.
Scheme design
Our company's technical personnel and the owner negotiate to determine the site monitoring point map. There are 20 monitoring points in the site, all of which adopt HD spherical cameras, which can reach 360 °, so that the site situation of the whole reservoir can be seen. The WIFI module of Mesh network is an important part of the remote picture transmission manufacturer signal transmission. Due to the inconvenience of point-dispersed power collection, solar energy system is used for power supply. Based on years of experience in wireless transmission project scheme design and construction of our company's technicians, combined with the owner's monitoring of the wireless bridge point setting, a professional wireless scheme is designed for the wireless transmission system of this project.
20 monitoring points on site are transferred to the monitoring center through Mesh WIFI module for remote image transmission from the manufacturer to the point and point to point. Similar points are transmitted to the collection point through point-to-point transmission, and then transmitted point-to-point to the management and monitoring center for storage display through high-bandwidth wireless transmission devices.
