Description

Collisionproof early-warning system for ships

The present invention relates to technical field of radio, particularly relate to the technology of utilizing radio call and constitute the crashproof early warning system of ship with device.

Often there is ship, bump against in the rivers and lakes at sea, causes the accident generation of ship damage and casualties.Mostly have radar and computer apparatus on the ship now, why can also crash accident? because the degree of accuracy of radar is limited, especially under the condition of dense fog, provide a lot of incorrect signals sometimes, too many rub-out signal can make captain and crewman lose vigilance, when real danger is arrived, have little time to hide and cause ship collision accident.Therefore, this old-fashioned situation that relies on radar fully needs to change.

Therefore, the objective of the invention is to utilize modern wireless communication technique, especially utilize radio paging technology and device, set up the crashproof early warning system of ship, avoid or reduce the generation of ship collision accident.

The reason that crashes is a lot, and most important reason is to fail in time to find ship, so that finds ship time to have little time to avoid.Crash so cause.If the early warning system of setting up can in time be found ship and provide early warning signal effectively, just can reduce or avoid crashing.

Early warning system of the present invention is to adopt wireless signal transmission and receiving trap are set on each ship, radio paging signal especially is set transmits and receives device, and the device that signal is processed and displayed, early warning sound devices etc. make ship can receive its signal of ship on every side effectively, the position of ship around showing on display screen, and nearby ship and this ship at a distance of within the certain distance time, provide early warning signal, make the vigilant and operation in time of crewman, crash avoiding.

Fig. 2 adopts 6 kinds of two examples that frequency is launched, and Fig. 2 a adopts 6 transmitters to launch,

Fig. 2 b has adopted variable voltage control generator VCO mode to launch the key diagram of the signal of 6 kinds of frequencies.

Fig. 3 is the block scheme that has adopted the receiving trap of variable voltage control oscillator circuit.

Fig. 4 is the design of panel of 6 different frequencies of reception of receiving trap.

Fig. 5 is display screen form and an example showing thereof.

Consult Fig. 1, the left side is a sender unit among Fig. 1, and the right and lower right are signal receiving devices, constitutes system of the present invention jointly.

In the sender unit, T is a clock, and GPS is the position instrument, and CPU1 is the central processing unit of emitter, and R is a memory, and KB is a keyboard, and ECD is a scrambler, and TX is a transmitter.

In the signal receiving device, RF is a signal receiving unit, and DCD is a demoder, and CPU2 is the central processing unit of receiving trap, and SC is a display screen, and SL is the alarm sound unit, and SBB is the paging prewarning unit.

POW is a power supply, and it can be direct supply or AC power, generally speaking, match with the electric power system on the ship, adopts the electric power on the ship to power, and is so comparatively economical.If the employing powered battery can be used for the not oversize time.POW is to the each several part supply electric power that transmits and receives device.

Sender unit emission ship itself and some parameters that are in operation thereof.Parameter is a lot, and for example parameter is name of vessel or name of vessel code name, the present position of ship, and course and the course that will navigate by water, headway, the ship kind, the ship type, dead weight or general assembly (TW), the nationality of ship, or the like.Can select the most important parameter of part to launch.Generally speaking, launch the ship code name, allow other ship know the existence of this ship, the present position of ship, course, speed or the like.If very large scale tanker, preferably sending is the parameter declaration of very large scale tanker, can cause very big loss and infringement because crash.

Adopt position instrument GPS to provide the ship present position in the emitter, utilize the poor of clock T and twice position, can calculate the speed and the course of ship by CPU1, if ship has the prearranged heading parameter, can be input among the memory R, by CPU1 control output, the name of vessel code name also can store in memory R, KB is a keyboard, can import the supplementary parameter signal that some need be launched by KB, for example " ship weighs 50,000 tons; please be careful ", then can import this class parameter, simultaneously, also can import some urgent provisional injunctions or the like by keyboard KB by keyboard KB.Generally speaking, system operates automatically by preset program.

All parameters are input among the scrambler ECD by the COU1 instruction and encode, and have compiled the parameter signal of sign indicating number and have been launched by transmitter TX.

All parameters are encoded by radio paging code, and transmitter TX is the radio paging signal transmitter.

In order to make each crewman all will watch out for the danger that crashes, native system is reported to the police with pager (BB machine) to each Equipment of Crew on the ship, do not draw among Fig. 1, but transmitter TX has a dotted line to communicate with SBB in the drawings, expression SBB has signal and also sends (arrow is represented) from TX, make the BB machine of this ship ring machine, be used for urgent prompting.

For anti-stop signal bumps against, will be with 3 to 6 different frequencies with different time interval emission above-mentioned parameter signals, for example can adopt with the frequency duplex mode, transmit and receive, can adopt different frequency-hopping modes, for example, receive with

frequency

2,4,6 with

frequency

1,3,5 emissions, or the like, the ship around making can well receive.Because the ship navigation is across the sea, in the lake, on the river course, does not have anything to stop along the water surface, signal is under same emissive power, and what can transmit is far away.Therefore, adopt less emissive power signal just can transmit larger distance, for example adopt the emissive power of 5W, the signal radius will 5 nautical miles or more than.Such scope is enough to preventing to crash.

Consult the signal receiving device part of Fig. 1, RF is a signal receive section, the signal that receives is delivered to demoder DCD and is decoded, carry out signal Processing by central processor CPU 2 then, treated signal is sent to display screen SC and shows, as ship at a distance of for example in 1 nautical mile the time, CPU2 starts alarm sound SL and sends the predetermined sound, the sound for example is every tucket of two seconds of two seconds sound and so on, remind the crewman to note operation, very near for example in 200 meters the time as ship, CPU2 starts BB machine early warning circuit SBB, and TX sends signal by sender unit, and the warning that the crewman is worn rings machine with pager (BB machine), make the crewman ready, prevent the accident that crashes.The BB machine early warning circuit SBB that CPU2 starts is the unidirectional emitter TX partly that leads to, and this configuration is simplified whole device.

In order to receive the signal of ship on every side with several close frequencies emissions, RF must adopt scan mode to receive, may have the signal of 6 frequencies of as many as for example, RF will jump respectively and receive on these 6 frequencies so, can adopt automatic jump scanning formula, or the reception of manual control button great-jump-forward frequency, or adopt computer software, realize that with software control the great-jump-forward frequency receives.

The course of ship is extremely important, if the course is preset in emission in the signal parameter of emission, then CPU2 can calculate the track that each ship will navigate by water, by the track that relatively calculates, can make timely adjustment to the coursespeed of ship of oneself, can avoid better crashing.

Be two kinds of device situations when for example adopting 6 frequencies of emission among Fig. 2, certainly, also can adopt 3,4,5 frequencies or the like.Fig. 2 a is the example that adopts 6 transmitters, and each transmitter is with a frequency emission, and for example 6 frequencies are respectively 170.00M, 170.25M, 170.50M, 170.75M, 171.00M, 171.25M, launch by transmitter TX1 to TX6 respectively, though the equipment complexity can be carried out.Fig. 2 b is the mode that has adopted variable voltage control generator VCO, VCO provides fundamental frequency, is regulated by the integrated circuit (IC) of other cooperation and the CPU that carries out the data input, can realize launching a plurality of frequencies, XF is the frequency multiplication part, is launched by antenna behind the signal frequency multiplication.Adopt the circuit of Fig. 2 b comparatively simple, it is no problem to be used for launching 6 frequencies shown in Fig. 2 a, and the circuit of Fig. 2 b can be launched the signal of more different frequency.

Fig. 3 is the receiving trap block scheme that adopts variable voltage control oscillator circuit, and only explanation receives the case part of a plurality of frequencies.Receiving unit can not adopt the mode shown in Fig. 2 a, can not respectively receive a frequency respectively with a plurality of receivers, concentrate the circuit of handling by CPU2 again, receive and can only adopt with the similar circuit of Fig. 2 b, circuit shown in Figure 3 can receive a plurality of frequencies, promptly adopts circuit shown in Figure 3 in the signal receiving device of the present invention.

Fig. 4 is a design of the panel of receiver when receiving 6 different frequencies for example.Panel is marked with 6 frequency markers of 1-6, and the figure notation top is provided with the flashing light indication, is used to indicate the frequency of working.This is a kind of panel designs example, can also adopt the design of alternate manner certainly.

Fig. 5 is the key diagram that shows ship relative position and situation of movement on the display screen.Deliver to upward demonstration of display screen SC by the data that CPU2 handles, as shown in the figure, middle C represents it is this ship, go just southwards, S represents south, and N represents north, W represents the west, and E represents east, represents distance with lattice, dotted line before the ship is represented the prediction rail speed that calculates, and for example, the length of side of each lattice is words of 1 nautical mile, about 3 nautical miles away from C ship in A ship be, the forward southwestward sails, about 3 nautical miles apart from the C ship in B ship, the forward north by west sails, and knows among the figure that demonstration can not crash.Can intuitively show with the grid mode on the display screen SC, can intuitively not show yet, and directly provide code name and other parameter values of certain ship with numbers and symbols, A ship for example, position be north latitude * degree * minute, east longitude * degree * minute, ship's speed per hour * * in the sea, the ship's head * * *, apart from my ship present 3.1 every in, or the like.

Each device of the present invention can be buied from the market and oneself is changed a social system, for example instrument GPS in position has various products to choose, the relative assembly and the receiving trap of radio paging signal emission can be changed a social system voluntarily by the explanation of existing apparatus instructions according to the present invention, promptly can be made into.Apparatus system of the present invention also can all be contained in the suitcase, and is easy to carry, easy-to-use, takes on the ship, connects with the mains and just can use.

The boat of navigation is only all adopted in system of the present invention or the ship except that canoe all adopts, and just can concur.Because the present invention has adopted ship initiatively to send signal and information, it is significantly different with traditional radar mode to make other ship receive the mode that detects.

After ship had adopted system of the present invention, every ship can be seen the situation of ship navigation on every side according to the signal that receives from the display screen SC intuitively, and the device of double early warning signal has been arranged again, reminded the crewman, enhanced your vigilance, and prevented to crash.Therefore, the enforcement of system of the present invention can bring good social benefit and economic benefit to shipping business.
