School/railway transportation long-distance WiFi wireless module wireless transmission system scheme
1. Campus Safety Requirements
Schools are places where education represents the future of the motherland. Students, parents, teachers and all social classes attach great importance to the safety of schools. In addition, in recent years, more and more negative campus news has come out from all over the world, such as campus fights, student bullying, hygiene problems in the school cafeteria, cheating in exams, and illegal invasion of the campus, all of which affect the safety of students and campus order, so the school School management must be further strengthened.
In this regard, the tool to assist the management of the college is undoubtedly the video surveillance system. Some campuses are larger, such as university towns and wireless video surveillance systems that require universities and other environments that are inconvenient for wiring construction.
Second, the advantages of long-distance WiFi wireless module wireless video monitoring system
1. Simple layout, no wiring, and simple maintenance
2. Compared with the wired monitoring system, it can save a lot of manpower, material resources and time costs
3. Suitable for most responsible indoor and outdoor environments, with a transmission distance of 1-20 kilometers
4. Strong expansibility and high flexibility
3. Brand advantage
For 10 years, it has been committed to the research and development and application of long-distance WiFi wireless module wireless transmission equipment, wireless bridges and other equipment, and has provided professional solutions, equipment and technical support for thousands of engineering projects across the country, with rich practical experience.
Fourth, the campus long-distance WiFi wireless module wireless video monitoring system structure
1. Network camera: real-time monitoring of teaching buildings, dormitories, canteens and other monitoring points in the campus teaching building.
2. Wireless transmission equipment: FRLRWIFI, a commonly used wireless transmission equipment in schools, etc.
3. Monitoring display + hard disk video recorder (NVR): Users can monitor the internal environment of the campus through the display, and the NVR is used to store monitoring information for future reference.
Railway long-distance WiFi wireless module wireless transmission scheme, railway wireless video monitoring system
1. Status Quo of Railway Monitoring Industry
In railway safety management, the main monitoring areas include railway lines, hubs, bridges, freight yards, stations, in addition, there are important places such as temporary construction along the railway, natural disasters (floods, landslides, etc.) cause various emergencies for emergency monitoring. .
There are many categories of railway system departments, and they are all over the country. They are not centralized and the local on-site environment is diverse, which is not conducive to the layout of wired networks; therefore, a wireless video monitoring system is established to realize key railway monitoring, wireless interconnection of departments, and complete real-time transmission of business data. Interactive, convenient for management personnel to discover accidents, dangers, hidden dangers, etc. in time, to ensure the safety of personnel and production and transportation.
For example, railway freight yards can wirelessly transmit transmission equipment through long-distance WiFi wireless modules, which is convenient and fast, without laying network cables to establish a wireless transmission network, and establish a wireless transmission system for railway freight yards to maximize and improve the safety management of freight yards. Before assembling the wireless transmission system, the complexity of the site line, monitoring distance, wiring difficulty, etc. must be fully considered. The use of wireless transmission equipment such as 2.4G wireless transmission can be used in some places that do not require wiring conditions.
Considering that most railway transportation distances are very long, it is not recommended to use analog wireless transmission equipment (because the transmission distance of analog monitoring equipment is generally short). It is generally recommended to use long-distance WiFi wireless module digital wireless transmission equipment. The wireless transmission system, video recording control, storage medium, function expansion, editing and recording in image transmission have obvious advantages.
Second, the advantages of railway long-distance WiFi wireless module wireless transmission system
①Easy remote monitoring of field operations:
In the control room, managers can remotely control the front-end camera through the wireless PTZ control device to comprehensively monitor the site situation. The content filled in the watch book and the light strip display status of the console can be clearly displayed in the monitoring room.
②Two-way voice:
While monitoring the work language of the front-end staff on duty, it can also realize two-way intercom between the control room and the staff on duty at the intermediate station;
③Remote video conference function:
The main venue can be set up to hold video conferences;
④Monitoring image transmission function:
All surveillance images can be transmitted to the superior unit through the network, and the superior leader can view the surveillance video only by logging in to the network;
⑤Connection with other systems:
Provide a network interface to access the website office network system;
⑥Storage function of monitoring information:
All monitoring information can be input into digital storage hard disk, automatic video loop coverage, select the hard disk storage capacity according to user needs.
