Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Explanation of terms: AIS (Automatic Identification System) ship automatic identification system; MMSI (Maritime Mobile Service Identify) maritime mobile communication service identification code, which is sent by the ship's radio communication system on its radio channel, and can uniquely identify various stations and A column of nine-digit codes for group call stations; RSSI (Received Signal Strength Indication) received signal strength indication, an optional part of the wireless transmission layer, used to determine link quality and whether to increase broadcast transmission strength.

[0021] See figure 1 with figure 2 , the bluetooth-based AIS ship mooring and unparking automatic positioning timing method of the embodiment of the present invention, comprises the steps:

Abstract

The invention discloses an AIS ship berthing and unberthing automatic positioning and timing method based on Bluetooth. The method comprises steps of S1, Bluetooth tags being installed on ships entering and leaving a port; S2, installing and deploying a Bluetooth base station in a harbor area; S3, establishing a corresponding table T1 of the unique identification of the ship and the Bluetooth label data; establishing a data corresponding table T2 of the berth number, the berth longitude and latitude and the berth RSSI value; S4, when the ship enters the recognizable area of the harbor area, the Bluetooth base station recognizing the Bluetooth label of the ship; S5, judging whether the identified ship is berthed and docked or not, and recording the berthing information; S6, judging whetherthe berthed ship is unberthed or not, and recording the unberthing information. The method is advantaged in that the Bluetooth tag and the Bluetooth base station are adopted for positioning and timing, when a ship berths, berths and unberths are accurately and automatically judged, and accuracy and reliability of AIS ship berthing and unberthing timing are improved, bluetooth equipment is wide inrecognition range and easy to install and maintain, and operation cost is greatly reduced.

Description

technical field [0001] The present invention relates to a kind of timekeeping method of berthing and unberthing of ships, in particular to a method for automatic positioning and timing of berthing and unberthing of AIS ships based on bluetooth. Background technique [0002] In order to strengthen maritime and port safety supervision, most supervision platforms currently use RFID electronic label platforms to effectively manage ships. [0003] RFID is an automatic identification technology that originated in the 1950s. It uses radio frequency to carry out non-contact communication and exchange data to achieve the purpose of identification. A typical RFID application system usually consists of an electronic tag that identifies a specific target object, a reader that receives the signal of the electronic tag, and application software. [0004] The main principle of the RFID electronic label platform is: install active electronic tags on ships entering and leaving the port a...
