Background and current situation:

With the accelerated development of urban modernization, the daily prevention and control of urban security management, as well as the safety prevention pressure for responding to major public emergencies such as terrorism and disasters, are becoming increasingly important. Mainly reflected in:

1. The increasingly complex urban environment has led to an increase in the difficulty of comprehensive monitoring

2. Traditional monitoring equipment is difficult to meet the requirements of large-scale security management

3. The device has a single application scenario and a low level of image data reuse and sharing

The urban high-altitude observation fire prevention and control warning system utilizes its sufficient height, coupled with dual window lenses and high-precision pan tilt zoom capabilities of ultra long distance high-definition visible light and large aperture far-infrared thermal imaging cameras, to easily achieve precise monitoring over a large area.

Requirement analysis:

With the accelerated development of urban modernization, the daily prevention and control of urban security management, as well as the safety prevention pressure for responding to major public emergencies such as terrorism and disasters, are becoming increasingly important. The concept of "Safe City, Safe China" has also been proposed accordingly. Building a harmonious society is a beautiful blueprint outlined by the Chinese government in recent times, and it is also an inevitable demand for economic development and people's lives. The foundation of building a harmonious society is to build a safe city. High altitude observation is different from ordinary image surveillance. It is installed at the highest point of high-rise buildings in the city to achieve precise target monitoring of large-scale, long-distance, high stability, and high-definition Zhejiang images. It is a high-end video surveillance method that combines large-scale scenes with specific target close-up shooting. The stability, long-range capability, precise control capability, night vision capability, and self-protection capability of the front-end observation system are important guarantees for the successful implementation of the high-altitude observation system. The combination of surrounding supporting facilities, especially the back-end control software that provides clear and smooth images and timely and accurate warning signals, is an important platform for its construction.

System Overview:

Haohai High Altitude Observation Security Monitoring and Early Warning System Application Haohai TechnologyLin Hai GuardianandNight EyesThe series of video surveillance products are designed to meet the needs of road traffic safety, environmental monitoring, urban counter-terrorism, emergency search and rescue, monitoring of illegal gatherings of people, and long-distance fire warning in cities. The front-end acquisition equipment is installed at the highest point in the city, using dual window lenses and equipped with ultra long distance high-definition visible light and large aperture far-infrared thermal imaging cameras. It has strong stability, telescopic ability, precise control ability, night vision ability, self-protection ability, and is suitable for remote dynamic all-weather cameras. The effective monitoring radius is greater than 5 kilometers. Adopting a highly integrated intelligent monitoring system, matched with high-precision intelligent pan tilt zoom, effectively reduces the damage caused by strong winds to front-end equipment and obtains stable images. Based on the GIS geographic information system, a digital landmark with a monitoring range is formed. Each installed high-altitude observation camera can be displayed on the map in a fixed-point manner, and the fully functional pan tilt zoom is used as a means to assist the pan tilt zoom in achieving a "selected is what you see, what you see is what you see" high-altitude observation system.

System functions:

The urban high-altitude observation and monitoring system consists of four interconnected and indispensable parts: video capture system, identification and warning system, data transmission system, and monitoring center management system.

1. Inspection and warning function: Regularly and uninterruptedly conduct comprehensive three-dimensional monitoring and scanning of the city, track the development of abnormal events and the full process changes of the situation, record real-time videos, and investigate and collect evidence.

2. Police situation verification function: Verify the alarm situation in the city. After receiving the alarm information, the camera can be adjusted to the alarm position for recognition and judgment to confirm whether the alarm information is true.

3. Rescue command function: Due to its high location, long monitoring distance, and wide perspective, it can effectively diagnose the traffic at the rescue point in the event of specific rescue events, reducing or avoiding the escalation of the situation caused by objective reasons.

4. Collaboration and cooperation function: It can effectively integrate and monitor the work of various security departments in the city.

5. Intelligent recognition and early warning function: It has auxiliary evidence collection and analysis functions for disaster prevention and counter-terrorism investigation in safe cities, providing effective high-tech support for technology driven policing and digital city management.

6. Comprehensive scheduling function: It can be combined with various existing information systems to play a greater role; Such as urban geographic information, weather forecast information, traffic condition information, etc.

7. Urban GIS system linkage: By integrating the geographic data digital information system (GIS system) data of the city into the high-altitude observation system, the target positioning function can be achieved. Through the established urban GIS digital coordinates, the alarm direction can be accurately located.

Advantages and Characteristics:

1. Intelligent detection, highly integrated;

2. Fire warning, fast, accurate and precise;

3. Data integration and resource sharing;

4. Command and dispatch, visual interaction;

5. Network freely and deploy quickly;

6. Open integration and data sharing.

By constructing an urban high-altitude observation and fire prevention and control warning system, accurate and dynamic monitoring of images can be achieved 24/7 within the jurisdiction area. This comprehensive video surveillance technology can not only take into account wide angle and wide range monitoring and observation, but also achieve targeted and precise monitoring. Especially in harsh weather conditions such as foggy, rainy, and low visibility at night, the system can work normally and achieve 24-hour uninterrupted, all-weather, multi angle, unobstructed, large-scale, and precise dynamic video monitoring. And the system has multi-level linkage and remote command functions. The entire system platform can be integrated into the urban sky network project, and the display of the screen can be achieved through the sky network project monitoring center.

Application fields:

For road traffic safety, environmental monitoring, urban counter-terrorism, emergency search and rescue, monitoring of illegal gatherings of crowds, and long-distance fire warning in cities, "large-scale, long-distance, high stability, and high definition" is a high-end video surveillance method that combines large-scale scenes with specific target close-up shooting. Mainly used in public security, transportation, border defense, military, coastal defense, environmental protection, forestry, large enterprise factories, etc.

Construction significance:

1. Fire warning for key urban areas

2. Urban fire warning and monitoring

3. Safety prevention and monitoring of key urban targets

4. Comprehensive monitoring of urban public security management

5. Key target monitoring of urban environmental pollution sources

6. Traffic diversion command and monitoring

7. National Key Cultural Relics Protection Monitoring

8. Remote monitoring of landslides and mudslides, floods and typhoons, and geological disasters

9. Remote observation and emergency command monitoring of unforeseeable sudden natural disasters

10. Preventing the occurrence of illegal and criminal activities, illegal gatherings, terrorist incidents, disruptions to social order, and illegal activities that endanger public safety has a certain deterrent effect and plays an extremely important role in post event evidence collection
