Description
Technical field
The utility model relates to a kind of visual control system, particularly boats and ships peripheral waters secure visual supervisory system.
Background technology
Boats and ships navigate by water between the harbour all over the world as marine equipment, frequently pass in and out the inland waters, are engaged in the alongside operation, and are coastal big owing to concentration of vessel with the inland waters, fishing zone distribution more complicated; Boats and ships are when the operation of anchorage, because the phenomena of drag of anchor takes place anchorage hydrometeorology characteristics easily; When boats and ships were engaged in the alongside operation, the personnel of boats and ships were many and mix up and down; The sternness of boats and ships security personnel form faces the threat of pirate and terrorist attack two aspects, and these have brought very big pressure all for the safe navigation of boats and ships and safety management work.
Container ship is because forepart construction characteristics and container assembling characteristics in addition, its blind area is bigger, is 1.5 times of the captain, and container ship navigates by water continually in the intensive waters of coastal fishing boat, narrow channel, and frequently lean on from the pool operation, radar is the same deficiency that exists in ship collision prevention.Because the radar shadow exists, when using the radar collision prevention, when his ship echo image to this ship radar shadow near the time, though close at hand, can't grasp ship situation at that time; When boats and ships are covered the elbow in the water channel of his ship or navigation channel at approaching by intervening obstruction,, can't detect barrier sheltered waters navigation ambient conditions because the radar radiowave is blocked; When using radar to dodge, it is slow in reacting on radar to dodge effect, ordinary radar, mark and draw and take to dodge action and the time will carry out more than 3 times the target ship at least, each 3min at interval needs time of 9min, even using the ARPA radar observes, target ship return vector shows also wants 1～2min, and stable vector shows will reach 3min, and his bearing changes also and can only turn to back 1～2min just can measure significantly at his ship; Radar to little thing mark and to the mark of the thing a little less than the radio-wave reflection may survey less than, incorrect use " sleet inhibition " and " wave inhibition ", and external environmental interference all may lost part thing mark and phenomenon such as false echo occurs, and these are operated for safety of boats and ships and bring hidden danger.
Also have International Maritime Organization (IMO) of the United Nations (IMO) relevant boats and ships in " ISPS " to protect in the clause and stipulate, be reply security personnel incident, require to take the precautionary measures:
Control personnel and article thereof are gone on board
The monitoring restricted area guarantees to have only the people through authorizing just can enter
Monitoring deck area and boats and ships peripheral region
Supervision goods and ship stores loading and unloading
At present, aspect shipping, the CCTV system only at the VTS center, important leg and harbor district management aspect obtained application, these all are application on land, do not install the CCTV system that is used to monitor boats and ships ambient water territory on the boats and ships additional.
