Ultra-long-distance wifi module emergency communication wireless video surveillance construction site solution, how to deal with sudden natural disasters has always been a topic of continuous research in countries around the world. From the research and development of emergency equipment to the establishment of emergency departments, there are different characteristics in different times. In the 21st century, the use of wireless emergency communication systems is the general trend of emergency rescue operations. So, what kind of emergency communication system has our country adopted in recent years? Next, the editor will introduce a comprehensive emergency communication system for ultra-long-distance wifi modules.
In fact, the emergency communication system is not only used in disaster relief operations, but also can play its unique role in the face of some large-scale temporary activities.
Advantages of emergency communication system:
1. No wiring, simple installation, adapt to local conditions, suitable for various environments.
2. The system construction takes a short time, saves a lot of manpower and material resources, and is easy to maintain.
3. Wide application range and long transmission distance. In the face of large-scale emergencies or activities, it can fully cover the scene.
4. High flexibility, easy to expand, in the face of secondary disasters or temporary expansion of activity venues, it can quickly rectify the system structure and quickly adapt to the environment.
Ultra long distance wifi module system structure:
1. Directional monitoring communication transmission module
The use of directional transmission equipment-wireless bridge, combined with the wind-solar hybrid power supply system, can solve monitoring problems, information transmission, power supply and other problems at the same time. It is mainly used in the scene of fixed monitoring point communication points.
2. 5G monitoring communication transmission module
Using 5G wireless transmission and transmission equipment, three 5G wireless networks can be used to transmit surveillance video or audio and video communication information back to the surveillance command center in real time.
3. COFDM mobile video communication transmission module
Using COFDM technology, it can realize fast mobile communication, which can be provided to vehicles, unmanned aerial vehicles, and individuals to carry, monitoring video and voice signals are transmitted back to the monitoring command center, mainly used in places without 4G signals, strong temporary, strong urgency, Drone shooting and other scenes.
These three modules can be individually or integrated. According to different application scenarios, different combination methods are more conducive to the functioning of the ultra-long-distance wifi module wireless emergency communication system.
Ultra-long-distance wifi module construction site dust online monitoring system solution, although some cities in China have indeed experienced severe haze weather in recent years, the domestic environment has been improving. Many cities have issued air renovation plans, and many of them have rectified factory exhaust systems. To strengthen the research and development management of automobile exhaust systems, the common is undoubtedly the management of dust monitoring and rectification in various places.
In order to strengthen the centralized control of dust pollution, improve the on-site monitoring capabilities of environmental protection departments, and promote accurate monitoring, management and control of air pollution sources, cities have begun to build construction sites, mining areas, roads, warehouses, and install dust detectors in places where dust is easily generated, such as ports and docks. device. Through these dust monitors, the concentration of atmospheric particulate matter, PM value, temperature, humidity, wind speed, wind direction and other data can be monitored in real time. Through the real-time monitoring and monitoring of data, dust pollution can be prevented and rectified in time.
However, for the temporary construction site, it is necessary to establish a dust monitoring system or use the power of the ultra-long-distance wifi module wireless transmission system. Why install dust wireless video surveillance system on construction site? At present, most construction sites should install a safety monitoring system, which is not only a requirement of the municipal government, but also a need for engineers to facilitate on-site monitoring and management. Now, with the rise of dust monitoring, why not combine a dust monitoring system with an on-site wireless video surveillance system?
Through the integration of dust monitoring and wireless video monitoring system, managers can remotely monitor the on-site environment of the construction site anytime, anywhere. At the same time, the on-site environmental data of the construction site can also be shared with the environmental protection department, so there is no need to reconsider the construction and use of the dust monitoring system.
Here, I will talk about the advantages of the ultra-long-distance wifi module wireless video dust monitoring system on the construction site:
1. The installation is simple, no wiring is required, and measures should be taken according to local conditions.
2. The construction period is short, the two systems are completed at one time, saving time and effort, and simple maintenance.
3. Wide application range, long transmission distance, strong adaptability, and can be used in various harsh environments.
4, high flexibility, easy to expand, can easily expand the system structure.
The composition of the wireless video dust monitoring system:
Construction site 1: Some important locations on the construction site, such as materials, machinery storage, warehouses, tower cranes, etc. The surveillance images captured by the surveillance cameras are transmitted to the temporary computer room/security room/site management center through the ultra-long-distance wifi module wireless bridge.
Construction site 2: Dust-prone locations, such as excavator work points, places where vehicles travel, etc. The dust and noise status of the construction site can be reflected in real time through the dust and noise monitor. Then the data of the monitor is transmitted to the temporary computer room/security room/site management center through the wireless bridge.
Temporary computer room: Security personnel and managers can share monitoring data with higher-level departments or relevant government and environmental departments by linking to the Internet.
