A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
The present invention provides a kind of bridge bridge opening anti-collision warning methods, illustratively, as shown in Figure 1, the method includes
Following steps:
Step 1: ship indicates to advance according to the bridge mark on bridge opening；
Bridge mark is arranged on the position of bridge opening top center, and ship is according to the instruction of bridge mark along bridge opening intermediate vertical line
Direction advance.
Step 2: when ship enters the distance of reaction of infrared equipment, the infrared equipment judges the height of ship,
Processing step is executed according to judging result；
Infrared equipment is mounted on the position of bridge opening top center, and the infrared ray of infrared equipment transmitting is in a horizontal state and and bridge
Hole vertex position flushes, and the direction of the launch of infrared ray and the driving direction of ship are opposite, senses ship with this convenient for infrared equipment
Height only.When ship enters the distance of reaction of infrared equipment, since the infrared ray of infrared equipment transmitting is in a horizontal state, at this time
There can be two kinds of situations:
Situation one: the height of ship is lower than the height of infrared ray, although ship comes into the distance of reaction of infrared equipment,
But ship is in the lower section in infrared induction area, and infrared equipment incudes less than ship, therefore infrared equipment does not make a decision, and does not also do anti-
It answers, the height for defaulting ship is less than limit for height, and ship moves on.
Situation two: the height of ship is higher than the height of infrared ray, infrared to set when ship enters the distance of reaction of infrared equipment
The infrared ray that preparation is penetrated can be radiated on ship, to sense the height of ship.Since the height of infrared ray is and bridge opening
Overhead height is identical, therefore the height of ship is not less than the height in bridge opening, and ship can not pass through.When ship is by infrared equipment sense
It should arrive and continue for some time, illustratively, for for 5 seconds, when ship is sensed by infrared equipment and is for 5 seconds
Between, infrared equipment judge ship be more than bridge opening limit for height, infrared equipment directly to alarm send signal, alarm alarm with
Ship's staff is reminded to turn in time, the mode of alarm can be sound and add flashing light alarm, is also possible to broadcast alarm, is not limited to
This.Infrared equipment is alarmed after persistently incuding 5 seconds, is conducive to that aerial sundries is avoided to block the mistake of alarm caused by infrared ray
Report, such as aerial polybag, flying bird etc., wherein duration can be adjusted according to the actual situation.
Step 3: surveying wide distance-measuring equipment and measure the width at ship different height, and measures each width place of the ship
Deck and survey the shortest distance between wide distance-measuring equipment；
It surveys wide distance-measuring equipment to be mounted on the position of bridge opening top center, and is provided with multiple measuring mouths, each measuring mouth
It is different from the acute angle of horizontal position, illustratively, 10 measuring mouths are provided with, are in 5 degree between two neighboring measuring mouth
Angle is in 45 degree angles between two measuring mouths of lie farthest away, can be measured by the measuring mouth of the multiple and different angles of setting
Width at ship different height.It wherein, can be with by increasing the quantity of measuring mouth and reducing the angle between adjacent measuring mouth
More ship width values are obtained, obtained result is more accurate.The ship that height does not transfinite moves on, and surveys when entering
The measurement range of wide distance-measuring equipment is surveyed between deck and the wide distance-measuring equipment of survey where wide distance-measuring equipment measures each width of ship
The shortest distance, and by this shortest distance data transmission to processing equipment.Wide distance-measuring equipment is surveyed while measuring ship width, also
Whether the course line that ship can be monitored yaws, once ship yaws, sounds an alarm prompt crewman at once and carries out course line correction.
Step 4: processing equipment according to the horizontal position where each width of the ship and survey between wide distance-measuring equipment away from
From the horizontal position calculated where each width of the ship and the distance between survey the horizontal position where wide distance-measuring equipment；
After processing equipment receives the shortest distance data that the wide distance-measuring equipment of survey is sent, data are updated to range formula
In, formula is as follows:
A=k × Bsin θ
Wherein, between the horizontal position where the wide distance-measuring equipment in horizontal position and survey of the A where each width of the ship
Distance, B is deck where each width of the ship and surveys the shortest distance between wide distance-measuring equipment, and θ is the wide survey of surveys
The acute angle of each measuring mouth and horizontal position away from equipment, k are safety coefficient.When having wave due to the water surface, ship can be with
The water surface floats up and down, at this time between the horizontal position where each width of ship and the horizontal position where the wide distance-measuring equipment of survey
Distance will time changing, it is therefore desirable to safety coefficient k be arranged, the value range of k is less than 1, that is, the value of the A acquired is than ship
The actual range between the horizontal position where the wide distance-measuring equipment in horizontal position and survey where each width is small, is conducive to avoid ship
It collides at the top of bridge opening, safety coefficient k can be adjusted according to the size of water surface wave when only floating up and down, specific: when
When water surface wave is larger, safety coefficient k can be turned down suitably；When water surface wave is smaller, safety coefficient k can be tuned up suitably.
Illustratively, the deck where a certain width of ship and the shortest distance surveyed between wide distance-measuring equipment are 100m,
That is B takes 100, and the infrared ray emission port of infrared equipment and the acute angle of horizontal position are 15 degree, i.e., θ takes 15, k to take 0.8, will count
According to substituting into above-mentioned range formula, it can be calculated A and be approximately equal to 21, is i.e. horizontal position where the ship width is set with wide ranging is surveyed
The distance between the horizontal position at standby place is 21m.
Step 5: the processing equipment is according to the horizontal position where each width of the ship and surveys where wide distance-measuring equipment
Horizontal position in conjunction with where own database obtains each width of the ship of the distance between horizontal position bridge opening width；

| H | ... | 19 | 20 | 21 | 22 | 23 | 24 | ... |
| W | ... | 20 | 21 | 23 | 26 | 30 | 35 | ... |
The bridge opening width data of a part of differentiated levels is given in table (1), wherein H indicates to survey wide distance-measuring equipment
To the distance of the horizontal position where each bridge opening width, W indicates the bridge opening width of differentiated levels, for different arch bridges
Hole, H, W in database are different from, and H relationship corresponding with W is not also identical.As shown in above-mentioned example, ship is had calculated that
The distance between the horizontal position where the wide distance-measuring equipment in horizontal position and survey where a certain width is 21m, that is, surveys wide ranging
The distance of horizontal position where equipment to bridge opening width to be obtained be 21m, in conjunction with table (1) can obtain 21 it is corresponding be 23, i.e., should
The bridge opening width of level height is 23m.
Step 6: the processing equipment is by the ship of the bridge opening width and the bridge opening width the same horizontal position
Width is compared, and judges whether ship can pass through according to comparison result.Specifically, described judge ship according to comparison result
Whether can only pass through specifically:
When there are the bridge opening width no more than the ship width for being in the same horizontal position with the bridge opening width
When, then processing equipment judges that ship cannot pass through, and triggers alarm and alarm；
Otherwise processing equipment judges that ship can pass through.
As shown in above-mentioned example, the bridge opening width that level height is 21m is 23m, and a certain width with ship is that 20m is
Example, 23m > 20m, the bridge opening width of the same horizontal position are greater than the ship width at this time, and processing equipment judges that ship can pass through；
By taking a certain width of ship is 24m as an example, 23m < 24m, the bridge opening width of the same horizontal position are less than the ship width, place at this time
Reason equipment judges that ship cannot pass through, and triggers alarm and alarm；By taking a certain width of ship is 23m as an example, at this time
The bridge opening width of 23m=23m, the same horizontal position are equal to the ship width, and processing equipment judges that ship cannot pass through, and touches
Hair alarm is alarmed.
