Intelligent OBU (on board unit) carried by ship and based on wireless sensing technology

Abstract

The invention discloses an intelligent OBU (on board unit) carried by a ship and based on a wireless sensing technology. The intelligent OBU carried by the ship and based on the wireless sensing technology is an onboard terminal device which uses the wireless sensing technology to locate the ship and recognize identity of the ship. The onboard terminal device is composed of an RFID (radio frequency identification device) module, a satellite positioning module, a wireless ad hoc network module, a master control module, a power module and a human-computer interaction module. The wireless sensing technology is an intelligent ad hoc network technology which adopts an IPV6 (internet protocol version 6) communication protocol to perform enveloping processing on data. Positioning and identity data of the ship is transmitted to a computer system by using the wireless sensing technology, and basic data support is provided to business software. The computer system achieves the functions of positioning and tracking the ship in real time, inquiring trajectories of the ship, recognizing the identity of the ship and the like by processing the satellite positioning data and the identity recognition data of the ship, and therefore the intelligent OBU carried by the ship and based on the wireless sensing technology plays an important role in promoting improvement of remote management of inland ships and enhancement of shipping information management and service levels of the inland ships.

Description

technical field [0001] The invention discloses an intelligent ship-borne OBU based on wireless sensing technology, and relates to the technical fields of ship positioning devices and identification. Background technique [0002] At present, there are mainly two types of identification and positioning technologies used in waterways, one is GPS navigator, the other is AIS ship automatic identification system, and other systems such as RFID coexist with the above systems in the waterway. [0003] The GPS system tracks 3 or 4 satellite signals at the same time, measures the distance to the satellite, and realizes real-time, continuous, global high-precision positioning. The GPS navigator uses modern computer technology to calculate and display the speed, course, track deviation and wind, The current pressure difference has navigation functions such as setting waypoints, planning routes, and displaying the distance and time to reach the waypoints. However, the GPS system cannot c...

Problems solved by technology

This kind of common vehicle in the prior art uses OBU, which is limited by the communication distance, and can only be simply applied to short-distance touch environments such as highway tolls, and is not suitable for the use of surface ships.

At the same time, the power consumption of the vehicle-mounted OBU in the prior art is large, and the battery needs to be replaced frequently when using batteries for power supply, which brings inconvenience to use; and, applying the existing vehicle-mounted OBU technology to the ship-borne environment will inevitably Faced with the problems of shockproof, waterproof, dustproof, sunscreen and other usage environments, existing technologies cannot cope with such high-demand usage environments
