I. Project Overview: This solution is aimed at the fog and haze in special areas such as bridge channels, inland waterways, sea lanes, navigation beacons, and ships. Using high-end fog-imaging technology, fog-imaging can be carried out during daytime misty weather, making it far away. Distance targets can be clearer. It also integrates advanced communication technologies such as microwave / optical fiber communication technology, digital video processing technology, IP communication technology, and optical fiber communication technology to establish digital remote day and night monitoring of the channel. The front-end monitoring acquisition point is generally set at the height of each observation tower on the channel. Each monitoring point operates and controls the focal length of the front-end camera and the movement of the PTZ through a wireless transmission system. Through the real-time angle data transmission of the gimbal, combined with the GIS geographic information system, it can realize the accurate positioning of the real-time situation of the channel, and record the real-time situation of the channel in 24 hours under various weather and light conditions. 2. Demand analysis: China is one of the earliest countries in the world to use water transport. With the development of transportation, water transport requires the communication of waterways of various water systems to communicate with each other and connect to the network. The safety management department of waterway waterways needs to know the normal movement of ships in real time. , Overweight situation, search for help and accurate location, make a record of the number of the ship entering the area for future reference. China is constructing “digital water conservancy” and “smart water conservancy”, comprehensively constructing a remote video real-time monitoring system for water conservancy systems, real-time dynamic monitoring of possible or ongoing floods, dangers, and disasters, and timely prevention and remedial measures can be taken to improve flood prevention The effectiveness and reliability of flood control work will play an important role in reducing flood disasters, alleviating flood control pressure, and protecting people's lives and property. With the development of security informatization, traditional monitoring equipment has problems due to the small monitoring range, low resolution, and poor night vision capabilities ...

The intelligent traffic monitoring system transmits the on-site images in the surveillance area to the command center through the monitoring system, so that managers can directly grasp the traffic conditions such as queuing, congestion, and signal lights, adjust the signal timing in time or use other means to divert traffic and change the traffic flow Distribution to achieve the purpose of traffic jams. So, what functions does the intelligent traffic monitoring system have? The following editors introduce the role of intelligent traffic monitoring system. The intelligent traffic monitoring system can intuitively monitor the escape direction of vehicles escaping from traffic accidents. The intelligent monitoring system is mainly installed on major arterial roads with large traffic flows and fast speeds or at major intersections that require traffic light control. It has a strong tracking effect on traffic death and escape accidents on major roads, and can assist police handling case to quickly determine the escape direction and Possible hiding places. The intelligent traffic monitoring system can intuitively monitor the vehicle type and color of the escaped vehicle in a traffic accident. Escape accidents caused by driving may leave scattered objects after the collision at the accident site, but the scattered objects must be carefully compared and a lot of investigations to determine the type and color of the escaped vehicle, and the monitoring of the smart bayonet can be used to intuitively monitor the traffic The type and color of the escaping vehicle has saved a lot of human and material resources for the detection of the escaping accident. The intelligent traffic monitoring system can intuitively monitor the characteristics of escape drivers in traffic accidents. For some unlicensed or fake license vehicles escaping after a traffic accident and unable to track the evasive vehicles, the intelligent monitoring system of some important bayonet can be used to grasp the characteristics of the driver, appearance, gender, hairstyle and other characteristics of the vehicle driver, Can provide a variety of clues for the detection of cases. ...

As a comprehensive and special transportation hub, an international airport has a security monitoring system that is different from general security systems. It has many internal working institutions, usually including public security, fire protection, safety bureaus, terminal management centers, and emergency command. Centers, traffic management centers, security inspections, customs, aerodrome management departments, border guards, luggage, garages, health inspections, fuel supply, etc. There are nearly 20 categories. Each department is relatively independent and intersecting with the airport's security management, and its needs are diverse. Characterization. Surveillance systems Airport security systems usually include three categories: video surveillance systems (CCTV), entrance and exit control systems (ACS), and perimeter alarm systems (PAS). The three subsystems are independent of each other on the surface, but through the effective integration of information resources and preventive measures, a full-featured intelligent security system can be constructed, enabling the airport to have more comprehensive and effective preventive capabilities and ensure safe operations. Digital optical transceiver monitoring requirements and analysis and protection at important airports: Guarantee video surveillance system: International airport covers a large area. Large international airports have 2 main terminal buildings, 3 main runways and corresponding 218 parking spaces, 70 The boarding bridge has complex traffic roads and supporting facilities, and the number of surveillance cameras is large, ranging from a few hundred roads to as many as a thousand roads. Nearly a thousand points use Tiandi Albert ’s latest highly integrated and modular design mixed insertion series Optical transceiver products. Large flight areas, large terminal buildings, large passenger and cargo flows, large aircraft takeoffs and landings, frequent vehicle activities, air defense security and ground security, internal security and perimeter security are all fully real-time, zero-latency videos Switching displays and camera controls places stringent requirements. Due to the decentralized buildings and different functions, the monitoring system installed everywhere will form a relatively independent supervision ...
