Port Personnel Container Asset UWB Location Tracking Solution

2023-07-05/ By Admin

The world's ports are large in scale, with a large number of containers and materials. There are difficulties to effectively manage a large number of materials and personnel.

At present, more applications in ports are GPS positioning systems. However, GPS satellite signals are easily blocked and refracted by the building, which leads to inaccurate positioning. UWB technology can effectively solve the problem of GNSS signal positioning in the case of obscuration.

SKYLAB has developed a high-precision UWB positioning management system. The system supports TWR/TDOA positioning algorithm. In the actual test of harbor in open area, the two-way ranging distance can reach 10 km, and the positioning accuracy is less than 30 cm. SKYLAB UWB positioning system can precisely locate forklift, container, cargo and personnel.

SKYLAB positioning management system uses UWB technology. Managers install UWB positioning base stations in the port area. Personnel wear UWB positioning tags, and the system can achieve accurate positioning of personnel. Container cargoes are also installed with UWB positioning tags, and the system can realize the accurate positioning of equipment assets. This can help managers to strengthen the management of personnel and equipment. It can reduce the safety hazards caused by unauthorized operation of employees.

UWB Positioning System Architecture

The architecture of SKYLAB UWB High Accuracy Indoor Positioning System consists of UWB Anchor, UWB tags, positioning engine and terminal display device.

(1) UWB Anchor: Install the UWB positioning base station in the sea port. The UWB base station communicates with the positioning tag to realize the function of positioning the UWB tag.

(2) UWB Tag: Staff wear UWB positioning tags, and items are bound with UWB positioning tags. The tags transmit UWB signals to communicate with the base station. Through the calculation of the positioning engine, the label itself is located.

(3) Location Engine: The UWB base station sends raw data to the positioning engine in real time. The positioning engine calculates the coordinate position of the positioning label in real time.

(4) Display Terminal: The positioning coordinates calculated by the UWB positioning engine are displayed on the terminal. The terminal may be a PC, a tablet, a mobile phone, and other devices.

Main functions of port UWB high-precision positioning system

(1) Real-time positioning

UWB positioning system can accurately display the location of port personnel, container materials and vehicles. Managers can track and master the site dynamics in real time, thus reducing personnel violations and ensuring material safety.

(2)Historical track

UWB positioning system can query the historical activity trajectory of personnel and running vehicles within a period of time. It provides data basis for personnel management. If an accident occurs, the historical track situation of the site can be.

(3) Work time statistics

UWB positioning system real-time statistics of port personnel working hours. It can count the personal attendance information in daily and monthly time period.

(4)Electronic fence

UWB positioning system can set electronic fence. It can realize the security management of key areas. Managers can also set permissions and violation alarms to ensure safe production in the area.

(5)One key call for help

Once personnel encounter danger or need assistance, they can use the UWB positioning tags they wear to make a one-touch call for help. The rescuer can carry out rescue according to the location of the help. It improves the efficiency of rescue and security rescue.
