First embodiment
Referring to fig. 1, fig. 1 shows a schematic structural diagram of an intelligent warning system for a ship according to a first embodiment of the present invention.
The intelligent ship alarm system 100 comprises a control processing unit 110, a communication unit 120, a data acquisition unit 130, a power supply unit 140 and an alarm unit 150, wherein the control processing unit 110 is electrically connected with the communication unit 120, the data acquisition unit 130, the power supply unit 140 and the alarm unit 150.
In this embodiment, the communication unit 120 is used to establish data communication with other vessels. The communication unit 120 receives radio signals transmitted from other vessels through the antenna to obtain navigation state information of the other vessels, and transmits the received navigation state information transmitted from the other vessels to the control processing unit 110, wherein the navigation state information includes navigation information of vessels such as a ship number, a ship position, a ship speed, a ship direction, and the like.
In this embodiment, the data acquisition unit 130 acquires the navigation status information of the present ship, and transmits the navigation status information of the present ship to the control processing unit 110.
In this embodiment, the control processing unit 110 sends out the navigation status information of the ship via the communication unit 120, so as to realize data communication with other ships. Meanwhile, the control processing unit 110 compares the navigation status information of the ship with the navigation status information of other ships, and when the comparison result reaches the preset early warning condition, the alarm unit 150 is controlled to alarm. According to different navigational speeds of the ship, preset early warning conditions are different.
When the navigation speed of the ship exceeds the preset navigation speed, the ship intelligent alarm system 100 enters an meeting alarm mode, the control processing unit 110 calculates the minimum meeting distance and the minimum meeting time of the ship and other ships according to the current position, the heading and the navigation speed of the ship and the current position, the heading and the navigation speed of other ships, the calculated minimum meeting distance and the calculated minimum meeting time are respectively compared with the preset meeting distance and the preset meeting time, and when the calculated minimum meeting distance is smaller than the preset meeting distance or the minimum meeting time is smaller than the preset meeting time, the control alarm unit 150 alarms to prompt a crew to perform best processing in time so as to avoid unsafe accidents caused by collision with other ships.
When the navigation speed of the ship is lower than the preset navigation speed and the duration exceeds the preset navigation time, the intelligent ship alarm system 100 enters an area alarm mode, the control processing unit 110 sets an early warning ring with the ship as a center and calculates the current position, the heading and the navigation speed of other ships according to the current position, the heading and the navigation speed of the ship, and when other ships enter the early warning ring with the preset range of the ship in the preset time, the control alarm unit 150 alarms to prompt a crew to best process in time so as to avoid unsafe accidents caused by collision with other ships. Wherein, when the speed of the other vessels is lower than the preset speed, the alarm unit 150 does not alarm.
When the ship is located at a preset port location, the intelligent ship alarm system 100 enters the port entering mode, and the control processing unit 110 turns off the alarm unit 150 due to the overlarge density of the ship in the port, so as not to cause unnecessary disturbance.
In this embodiment, the intelligent warning system 100 for a ship automatically switches among three warning modes according to preset conditions. For example, the preset voyage speed is 1.5 knots, and the preset voyage time is 5 minutes, so the intelligent warning system 100 of the ship enters the meeting warning mode as long as the voyage speed of the ship exceeds 1.5 knots. In the meeting alarm mode, the preset meeting distance can be 0.2 seashore, and the setting range can be 0.1-0.5 seashore. The preset meeting time can be 20 minutes, and the setting range can be 10-30 minutes. The alarm unit 150 is started to alarm whenever one of the calculated minimum chance time or minimum chance distance is lower than a preset condition. When the speed of the ship is lower than 1.5 knots and lasts for 5 minutes, the intelligent warning system 100 of the ship enters the regional warning mode. In the area alarm mode, the pre-alarm ring set by taking the ship as the center can be 0.2 sea, the set range can be 0.1-0.5 sea, and other ships can enter the pre-alarm ring to start the alarm unit 150 to alarm after calculation. The preset time may be 30 minutes, or other times may be set. In the area alarm mode, when the speed of the other vessels is less than the preset speed (1.5 knots in this example), the alarm unit 150 does not start to alarm even if the other vessels enter the early warning ring of the present vessel within the preset time (30 minutes in this example). When the position of the ship enters a preset port position, the intelligent ship alarm system 100 enters a port entering mode. In the port entry mode, the alarm unit 150 is turned off to avoid unnecessary disturbance due to the excessive density of the vessels in the port. Because the sailing speed of each ship is very low in the port, and the sailing of each ship is careful under the condition of overlarge density, the possibility of collision is low. The three modes of the alarm mode, the regional alarm mode and the port entering mode can be automatically switched according to the navigational speed of the ship and the position of the ship, the navigation under different navigational speeds at different positions is automatically adapted, and the safety of navigation is ensured.
In this embodiment, the navigation status information of the other vessels received by the communication unit 120 includes the vessel numbers of the other vessels, and when the vessel number of the other vessel is the friendly vessel set by the control processing unit 110, no alarm is performed regardless of whether the navigation of the other vessel meets the condition of the intelligent alarm system 100 for the vessel.
In this embodiment, the data communication between the present ship and other ships is realized based on the ship automatic identification system (Automatic Identification System, AIS), and the relationship between the ship name and the identification code of the AIS equipment is mutually corresponding and unique, and is registered through the relevant departments. The method comprises the steps of collecting AIS equipment information registered by related departments, manufacturing a database of one-to-one correspondence of water mobile communication service identification codes (Maritime Mobile Service Identify, MMSI) and ship names, embedding the database of the ship names into AIS system software, and searching by automatically collecting identification codes through a received AIS dynamic information systemAnd displaying the ship name of the corresponding ship in the database. As the number of ship names stored in the database is up to several millions, MMSI is orderly arranged for achieving quick indexing, and a binary search method is adopted for searching, so that the search speed is improved. The database for embedding the ship name in the AIS system software has the advantages of high display speed and no influence on normal operation of the AIS system. For example in the number 1X 10 6 Searching a database, namely finding a target in the last two halves according to the condition of the maximum searching times, wherein the time complexity of the two halves is O (N), and the method is as follows:
O(N)＝log (2) 1×10 6 ，
the corresponding ship name can be indexed and displayed quickly by searching for about 20 times, which is much faster than searching in sequence. Through such scheme, solved among the prior art, AIS often can't show the condition of ship name information.
In this embodiment, when the position of the ship is located in some preset specific waters, the control processing unit 110 controls the alarm unit 150 to perform alarm prompt. For example, the control alarm unit 150 may give an alarm when the ship enters a custom channel in a domestic sea area of a commercial ship, a main anchor in a domestic sea area of a commercial ship, a temporary measure water area (a Korean water area on-line alarm) of a Korean (daily) fishery agreement, or the like.
In this embodiment, the power supply unit 140 provides power for the operation of the intelligent warning system 100 for the ship.
In this embodiment, the alarm unit 150 alarms under the control of the control processing unit 110.
In this embodiment, the alarm unit 150 alarms through two modes of voice and light. For each alarm that reaches an alarm condition, the alarm unit 150 reports the pre-stored alarm requirements for each alarm that reaches an alarm condition. The lamplight alarm can adopt a red flashing indicator lamp to carry out alarm prompt, and can be easily found by crews at various angles at a far place, so that the effect of alarm prompt is achieved.
When the position of the ship is located in some specific waters, for example, a custom channel of a domestic sea area of a commercial ship is entered, the alarming mode of the alarming unit 150 may be that the ship enters the custom channel water area of the commercial ship, please watch on duty, drive away as soon as possible, and disable anchoring, and when entering other preset related water areas, the alarming unit 150 carries out different alarming prompts for different water areas, so that a crew can take corresponding measures.
