Specifically, basic information of a ship in a preset water area is obtained, water level data of a specific area in the preset water area, bridge navigation height threshold calculation data and bridge pier position coordinates are collected, after the position coordinates of the bridge piers are collected, calculation is carried out according to the water level data and the bridge navigation height threshold calculation data to obtain real-time clear height data of the bridge, a bridge real-time navigation height threshold is obtained according to the real-time clear height data, a corresponding ship prediction course is obtained according to ship course and ship speed of the ship, a normal ship and an abnormal ship are distinguished according to the bridge real-time navigation height threshold and the ship prediction course, then the abnormal ship is tracked and monitored, and when the abnormal ship enters the specific area, the AIS, the VDES and the like, The method comprises the steps that a collision warning signal is sent to a ship in a VHF (very high frequency), LED (light emitting diode) and other communication or acousto-optic modes, ship personnel can take corresponding measures according to the signal, and workers on a bridge can take protective measures, so that the collision condition of the ship is reduced, or collision damage is reduced.
The invention can release the real-time clearance height and the pier position of the bridge to the ship in the modes of LED, VHF, AIS, VDES and the like, thereby taking measures in advance according to information.
The bridge navigation system can realize the functions of bridge clear height monitoring, ship superelevation monitoring and early warning, ship yaw monitoring and early warning and the like, thereby effectively guiding ships to safely pass through the bridge and ensuring bridge navigation safety. The invention supports the comprehensive display of information such as navigation clear basic scale of river-crossing buildings such as bridges, cables and the like which are built, built and built in batches of the channel network in the district, can monitor the navigation clear height of the bridge in real time according to the monitored water level change condition, and supports the comprehensive display based on the electronic channel chart.
In addition, the invention can also be applied to collision avoidance of other buildings on water, and the navigation height of the buildings is measured to compare with ship data, so as to analyze whether the ship has collision conditions and send out warning signals according to the analysis result.
Further, as shown in fig. 4, the bridge navigation height threshold calculation data includes a historical maximum water level height W, a bridge design clearance height H, a real-time water level height W, a distance D from a measurement point of the measuring instrument to the water surface, a reference point height value W', and a distance L from the reference point to the measurement point of the measuring instrument;
the step of processing the water level data to obtain real-time net height data of the bridge comprises the following steps:
the calculation formula of the real-time net height data of the bridge is as follows: h is H + W-W; wherein W is the historical highest water level height (the historical highest tide level height), H is the bridge design clearance height, and W is the real-time water level height;
the real-time water level height calculation formula is as follows: w ═ w' - (L-D); wherein D is the distance from the measuring point of the measuring instrument to the water surface, w' is the elevation value of the reference point, and L is the distance from the reference point to the measuring point of the measuring instrument.
Specifically, W is the historical maximum water level height, which can be the maximum water level height within a period of time, and is generally the maximum water level value in one fifty years; the bridge design clear height value H is the navigation clear height for the bridge design, and the parameter can be obtained through bridge design data; when the real-time water level height is measured, a reference point or a fixed point needs to be set at the position of the bridge, an elevation value w' of the reference point is obtained through a level gauge (and the elevation value of the reference point can be obtained through measurement of a professional measurement team with measurement qualification, such as a local hospital), then a measuring instrument is installed in water, the measuring instrument can be a water level measuring instrument, the distance D from a measuring point where the water level measuring instrument is located to the water surface and the distance L from the measuring point where the water level measuring instrument is located to the reference point can be measured through the water level measuring instrument, and the real-time water level height can be obtained through the measured data.
In addition, in order to ensure the accuracy of real-time clear height data, measurement can be carried out at a plurality of point positions, and then an average value is taken, so that the accuracy of a measurement result is improved; in the invention, besides the pressure type, float type or bubble type measuring instrument method adopted by the formula, the distance measurement can be carried out through a radar, namely, the real-time clear height data of the bridge is directly measured at a proper position (such as the topmost position of the designed clear height of the bridge) through the radar, so that another measuring scheme is provided, and the diversity of the measuring method is ensured.
In the real-time bridge clearance data calculation, the clearance margin setting is sometimes required to be considered, that is, a certain margin clearance height value FH is reserved in the bridge design, and in some cases, when a ship needs to use the margin clearance, FH can be added to the margin clearance value, that is: h + W-W + FH, but at this time, the bridge navigation height threshold is a proportional value of the real-time net height data, and in the present invention, the preferred embodiment is that the bridge navigation height threshold is ninety percent of the real-time net height data, so that the bridge navigation height threshold is smaller than the real-time net height data, thereby leaving some margin, that is: the margin is h 10%, and when the margin is less than FH, the margin is utilized in this way, and when the margin is greater than FH, the margin is of no use and is negligible. By the method, the ship can safely and stably pass through the position of the bridge, and the condition that collision danger still exists because the height of the ship is close to the real-time clear height of the bridge when the ship passes through the bottom of the bridge can not occur.
According to the invention, the water level value is monitored by the water level measuring instrument arranged below the bridge, the real-time net height data of the bridge is obtained by combining the technical parameter conversion of the bridge, and the data can be transmitted to the net height display board arranged at the bridge in a wired mode, so that the real-time net height data is displayed.

For the judgment of the ultrahigh ship, the invention adopts a cross distance measurement laser detection technology or a video identification technology or a communication message information acquisition technology, and combines an AIS system to obtain the ship number, longitude and latitude, course and speed of the ultrahigh ship, so as to realize ultrahigh detection and analysis of the ship in the navigable water area, and when the height of the ship exceeds a preset ultrahigh threshold value, whether the ship is ultrahigh or not is judged; for the ultrahigh ship, the ship owner can handle the passing behind the ultrahigh part of the ship after stopping the ship, if the ultrahigh ship continues to advance, monitoring personnel can clearly see the field situation from the video record, and shout and inform the field ship through the talkback function, and meanwhile, the platform can help management departments to obtain evidence about violation of regulations after the fact.
For the yawing ship, the invention can be provided with an induction display screen or voice or message early warning for inducing the yawing ship to correct the course, and the yawing ship can normally pass through the bridge after returning to a correct channel in a preset water area.

In the invention, the first area is set within the range of 1000-2000 meters away from a pier, and the setting of the first area is defined according to the outer edge line of a ship trajectory line concentrated area within a certain time period of a specific water area (bridge area); the second area is set to be within a range of 500 meters to 1000 meters away from the bridge piers, and is defined according to the edge lines of high-density areas in a ship track line concentration area within a certain time period of a specific water area (bridge area); the third area is set within a range of 500 meters from the bridge piers, and is defined according to the minimum safety distance of the bridge piers in a specific water area; the system comprises a first area, a second area and a third area, wherein the first area is an early warning area, when the target of an abnormal ship is found in the first area of 1000-2000 meters, the system sends out a boundary early warning signal, and the bridge area range, visibility and hydrological information are reminded through VHF; the distance between 500 meters and 1000 meters from the bridge pier is a second area (alarm area), when an abnormal ship exists in the second area, an alarm mechanism is started to prompt that a potential dangerous target exists, a worker in a control room is reminded to warn the coming ship to decelerate through sound and light or communication, and meanwhile, the intelligent camera automatically tracks and monitors the target or the full-coverage tracking and monitoring of the bridge area water area; the third area (emergency alarm area) is 500 meters away from the bridge pier, when an abnormal ship exists in the emergency alarm area, the abnormal ship is likely to collide against the bridge pier, tracking, recording and evidence keeping are carried out, and meanwhile, a corresponding accident handling program sequence is started, such as informing related personnel of emergency first aid preparation and the like.
