Remote wifi image transmission module video communication in mining area

2022-11-04 446

With the development of wireless technology, the application of wireless transmission technology is more and more accepted by all walks of life. It is easy to install, flexible, cost-effective characteristics, so that more industry monitoring system using wireless transmission, the establishment of the monitored point and monitoring center connection. Remote wifi image transmission module wireless transmission scheme technology has been widely used in modern communities, hotels, industrial and mining enterprises, transportation, water conservancy, shipping, public security, fire protection and other fields.

Remote wifi image transmission module video communication in mining area

First, wireless mobile video surveillance technology introduction

Vehicle-mounted mobile video transmission device adopts the core of the mobile communication technology COFDM (multi-carrier modulation technology), distance can figure the wifi module, video coding technology in high-speed mobile and urban building block transmission under the condition of stable hd audio and video, real-time multiple devices can be sent to a mobile command vehicle at the same time, again by the command sent to the command center, under the condition of shade, Transmission of real-time stable HD audio and video.


Ii. Customer on-site analysis

There are four coal trucks in the mine, each with two high-definition webcams. Each truck travels 6 kilometers to the monitoring center, with trees and a few buildings in the middle, and the rear end uses a monitor to watch the pictures.


Three, remote wifi image transmission module wireless mobile video transmission solution

The vehicle wireless mobile video transmission equipment is used to input audio and video signals synchronously, and the whole antenna is transmitted. The linear transmission distance is no less than 10km in the high-speed movement of non-line-of-sight, and 3-5 km in the non-line-of-sight condition.

Wireless mobile video transmission equipment is widely used in public security firefighting, road traffic, water conservancy, electricity, television news broadcasting, environmental protection, border patrol, oil field monitoring and other industries. Due to its technical characteristics such as multi-carrier, remote wifi image transmission module has "non-line-of-sight", and the advantage of "diffraction" transmission is that the device can realize stable image transmission in the environment that cannot be seen or blocked in cities, mountains, and inside and outside buildings, without being affected by the environment or environment.


Wireless transmission solutions in open-pit mining areas. Nowadays, with the rapid development of science and technology, high-tech safe communication means are used to prevent and stop all kinds of events that may occur. Along with the computer network communication technology, image compression processing technology and the rapid development of wireless transmission technology, security technology to guard against industry can use the latest communication and image/voice processing technology, by building a flexible network digital image transmission and control of the image, for the realization of the local and remote image monitor and alarm system provides efficient feasible wireless transmission scheme.


First, the advantages of remote wifi image transfer module wireless video surveillance

(1) Easy installation and construction, the use of wireless microwave to avoid or reduce the workload of network wiring, does not destroy the original environmental facilities, with short construction period, high cost efficiency.

(2) To achieve fast coverage, the video codec is responsible for converting the analog wireless video surveillance signals of the camera into digital signals, and at the same time compressing and transmitting the control signals. The video codec has a built-in 10/100M network adapter connected to the wireless transmission device through a network cable. The encoded and compressed monitoring information is collected by the wireless network to the traffic monitoring management center. The monitoring center can see the roads and intersections it controls. Monitoring personnel can remotely browse video images in real time through the local area network or Internet monitoring center, remote control the head. In order to fully guarantee the bandwidth of each monitoring point, the bandwidth of each monitoring point is adopted. Coding standard, low bandwidth occupation, can achieve high-quality image transmission and storage, long transmission distance, suitable for wireless transmission in broad areas of the city.


Ii. Customer on-site analysis

There are 16 monitoring points installed in the open-pit mining area, all of which are simulated ball machines. The monitoring center is 10 kilometers away from the mining area without obstacles. 16 monitoring signals are required to be transmitted at the same time, and the monitoring center can switch 16 monitoring states at will. The monitoring center needs to store data, video and switch.


3. Wireless transmission solution for remote wifi image transfer module

The analog camera is connected to the network video encoder to enter the wireless transmission device, that is, the video server, which can compress the analog video into the standard digital video transmission, and the back-end receiver directly enters the computer. The monitoring center can realize the control operation of the cloud platform and the camera.


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.


Remote figure the wifi module coal mine wireless video monitoring system solutions, in today's rapid development of science and technology today, using high-tech security communication means to prevent and stop all possible events, has become the life and property protection units and worker safety, ensuring the normal operation of all departments within their respective jurisdictions of strong measures "technology to security" become a consensus. As digital microwave wireless transmission technology and the rapid development of image compression processing technology, security technology to guard against industry can use the latest communication and image/voice processing technology, by building a flexible network digital image transmission and control of the image, to implement local and wireless remote monitoring and alarm system provides efficient, practical and cheap solution.


First, wireless video surveillance technology introduction

Based on digital signal and analog signal processing, wireless video surveillance can realize signal exchange, control, video storage and on-demand playback through microwave transmission. Through the establishment of a powerful central business platform, it can realize 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

At the coal mine construction site, six monitoring points should be installed and analog infrared cameras should be used. The monitoring center is 3 kilometers away from the construction site. The project department of the construction site is required to switch the situation of each monitoring point at will and see the image at the company headquarters. The camera is blocked in the monitoring center, the device can be placed on a high pole nearby to avoid the blockage, and the back end goes into the computer.


3. Wireless transmission solution for remote wifi image transfer module

Six analog cameras at the front end are connected with six 2.4G wireless transmitters to the monitoring center, and three supporting antennas in the monitoring center receive them one to two and enter the computer, which is accessed by the company headquarters through the Internet for remote monitoring.


Four, concluding remarks

Wireless video surveillance system has many advantages, such as strong user management function, good compatibility, convenient expansibility, distributed management, etc., creating and stimulating a new industry application mode in a wider range.
