Video forensics function: real-time monitoring and management of jurisdictional sea areas. After completion of the system, it will effectively crack down on smuggling, smuggling, illegal occupation of Marine resources and illegal development of ecological islands, and provide effective guarantee for the protection of Marine resources in the South China Sea

System composition:

The system consists of ship monitoring system, satellite transmission system and land monitoring center management system. Ship management monitoring system includes: integrated day and night imaging photoelectric tracking monitoring camera (visible light remote camera system, far infrared thermal imaging camera system, laser assisted lighting system), ship control management display console, photoelectric tracking software platform); The satellite transmission system includes: satellite signal transmission and control equipment. After the signal is on the satellite, a receiving system is built on the land or a land receiving base station is used by maritime satellite. After the video data is landed, it is transmitted to the land command center of Oceanic Administration by special network. The monitoring management center mainly includes: large screen display equipment, video image management server, hard disk recorder storage and other devices.


Main function

The main functions of the ship's navigation aid system are as follows:

1. Through the high-precision navigation aid monitoring equipment installed on the ship's roof, 24-hour imaging can be used to monitor the sea conditions around the ship in real time

2. The terminal control system shall be built in the cockpit of the ship. The terminal platform shall realize the automatic tracking of objects around the ship after linkage with radar and gyrocompass with intelligent tracking and monitoring software

3. The system transmits front-end video signals and data signals back to the land command center through the satellite transmission system equipment, providing reference for the command and decision of emergencies

4. Record the surrounding video image data in real time to provide rich data for the post-occurrence of the scene situation

Sea area monitoring

24-hour real-time monitoring of coastal waters, tracking and monitoring of passing ships, effectively crack down on smuggling, smuggling and other illegal acts, and when there is a ship distress signal in the law enforcement area, video confirmation, and give necessary help.

Ship management:

The ship's local video monitoring management, land video monitoring management and remote dispatch and command in case of emergencies are realized to reduce property losses and guarantee life safety, and to provide strong support and guarantee for water traffic safety.

Rescue at sea:

In case of maritime accidents or emergencies, assist salvage vessels at sea in timely rescue and rescue, and realize the timely control, dispatching and command of the land emergency command center on the scene of emergencies; Ensure timely and efficient rescue.

In addition to the above functions, it has the following functions:

1. Day and night imaging function

2. The color mode of visible light imaging system is very suitable for observation, monitoring and recognition under clear weather and good visibility; Black and white mode has higher video resolution and low illumination imaging ability. At the same time, the function of far infrared thermal imaging is not interfered by environmental factors to realize large-area search and monitoring in foggy days and nights, and then assisted by laser lighting system to realize detailed observation and monitoring of the targets searched by thermal imaging. The efficient combination of the three realizes the real sense of 24 hours of uninterrupted imaging monitoring function.

3. With the function of manual search, capture and automatic tracking of the target

4. The system is very convenient to operate. It can search, observe and monitor the target in the air at different speeds by manually manipulating the single rod, and automatically track the target that needs to be monitored.

5. Good visual axis stabilization function
