Description
Technical field
The utility model relates to a kind of servicing unit of marine vessel, particularly a kind of boats and ships collision prevention device for medium and small ship.
Background technology
Ship collision prevention problem is a problem very important in navigation research.On the one hand, the device product relevant to shipping anti-collision mainly ARPA radar and the AIS system of current domestic and international application, they are ship and ship, provide good interactivity between ship and bank, can play good collision prevention effect.But their price all costly, general only to equip in large vessel and ocean fishing vessel, the fishing boat of medium ship and light-duty tonnage is more than little use two kinds of equipments generally.In addition on the one hand, mostly the existing collision prevention device for medium and small ship is to utilize on a boats and ships anti-collision alarming equipment and ship original marine radar with the use of formation new equipment, but this device does not solve the larger problem in marine radar self blind area, so cause boats and ships in narrow water or to precision target anticollision poor-performing around boats and ships.
Summary of the invention
The technical problems to be solved in the utility model is to provide one and has comparatively high performance-price ratio for middle or small type ship, the boats and ships collision prevention device that practical collision free accident occurs.
In order to solve the problems of the technologies described above, boats and ships collision prevention device of the present utility model, comprise for measuring distant object orientation, the navar of distance and be used for measuring close-in target orientation around boats and ships, the ultra wideband device of distance, the information output of ultra wideband device is connected to one and can processes the target information obtained, analyze on the data fusion system of the different steering order of formation, navar is connected on data fusion system by a data pretreatment, the information output of data fusion system is connected to one for performing the performance element of steering order information.
Described data fusion system is also connected with and carries out the anticollision database of adjudicating for auxiliary data emerging system.
Described performance element comprises the warning system that can send alerting signal and can forcibly changing ship running speed, working direction or make the automaton of brake measure.
After adopting above-mentioned structure, due to the navar be connected with data fusion system and the ultra wideband device of setting, to the timely early warning of distant object, the problem that the blind area of navar is larger can either can be overcome again, identify in-plant target around boats and ships, give the alarm signal; First database technology is used for boats and ships collision avoidance system simultaneously, is very easy to captain commands, further increases the security of boats and ships; As can be seen here, boats and ships collision prevention device of the present utility model can reduce the generation of collision accident, particularly has higher cost performance for middle or small type ship, is significant to guarantee marine operation safety and operation.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model boats and ships collision prevention device.
Embodiment
Below in conjunction with the drawings and specific embodiments, boats and ships collision prevention device of the present utility model is described in further detail.
As shown in the figure, boats and ships collision prevention device of the present utility model, comprise navar, ultra wideband device and data fusion system, also comprise a data pretreatment be connected with navar, navar is the equipment of original indispensability on each boats and ships, and it mainly measures orientation, distance compared with distant object, the target range that data pretreatment exports navar, bearing signal obtain digital pulse signal through process, navar is connected on a data fusion system by data pretreatment, ultra wideband device is by signal source module, transmitter module, receiver module, the composition such as antenna and D/A converter module, it to transmit and mistiming between Received signal strength finds range by measuring, it is using nanosecond order or magnitude of subnanosecond as pulse signal, range resolution can reach centimetre-sized, its short-distance blind section can be shortened greatly simultaneously, minimum detectable range can reach several tens cm, this just overcomes the problem that navar blind area causes more greatly can not detecting around close-in target.Therefore, ultra wideband device is mainly used to orientation, the distance of measuring close-in target around boats and ships; The information output of said ultra wideband device is directly connected on data fusion system, wherein, data fusion system is the maincenter of boats and ships collision avoidance system, it is the main information processing section in system, it is in conjunction with anticollision database, the target information obtained navar, ultra wideband device carries out overall treatment, analysis thus form different steering orders, and the control of formation is determined to be transferred to performance element, completes anticollision prediction and arbitration functions.When there being risk of collision, data fusion system can send the information of different danger classes to performance element; The information output of data fusion system is connected to one for performing the performance element of steering order information.
Wherein, said performance element comprises the warning system that can send alerting signal and can forcibly changing ship running speed, working direction or make the automaton of brake measure, warning system realizes warning function, reminds driver, captain's danger barrier; And when data fusion system sends the higher instruction of danger classes, automatic forced is changed this foot speed, working direction or makes corresponding brake measure by automaton, thus effectively avoids the generation of accident.
Further, data fusion system is also connected with anticollision database, anticollision database, mainly rule of thumb accumulate, fuzzy algorithm is utilized and the target characteristic database set up to the shape of the power of target echo, sharpness, echo size, echo, it is mainly used in auxiliary data emerging system and adjudicates, and improves the accuracy and promptness that judge.It transfers data to captain simultaneously, facilitates captain to judge target.
Visible by above-mentioned structure, boats and ships collision prevention device of the present utility model detects the orientation of distant object by navar, distance, utilize ultra wideband device to detect the orientation of close-in target around boats and ships, distance, and by anticollision database, utilize data fusion system by above informix process, analyze, thus judge that this ship is in navigation, whether risk of collision is had with other object in berthing manoeuver process, and provide corresponding countermeasures, also it should be noted that ultra wideband device has very simple transceiver architecture and hardware circuit, simultaneously, ultra-broadband signal power is very low, frequency spectrum is very wide, to the navar on boats and ships, communication facilities can not cause interference, respond well.
