1、 Positioning requirements for the exhibition center
The personnel positioning of the convention and exhibition center includes two types of requirements: one is the positioning of internal staff, and the other is the positioning of exhibitors and visitors. These two positioning requirements are different, and the technologies used are also completely different. The positioning of internal personnel is mainly aimed at improving work efficiency, enhancing emergency and security measures, especially for large exhibitions where high-level leaders need to visit, so it is very necessary.
For the positioning of ordinary visitors, they cannot carry positioning tags and terminals, and can only use ordinary mobile phones. Therefore, the user's mobile phone is mainly used for location navigation. So the positioning does not need to be very precise, usually using WIFI and Bluetooth for positioning.
This article mainly introduces the first mode of positioning, which is based on UWB technology for locating internal personnel.
2、 Analysis of Problems in Convention and Exhibition Centers
2.1 In the exhibition center, the exhibition booths in the middle need to be temporarily deployed, so during the interval of the exhibition, it is actually a large house with no obstructions in the middle. However, during the exhibition process, the exhibition companies will build a large number of booths, which will block the signal and cause great trouble for the deployment of positioning base stations.
2.2 The exhibition center has a very large spacing, and there are certain requirements for the deployment location of base stations. They can only be deployed on the walls on both sides or on the top, and there are also certain requirements for aesthetics.
2.3 The exhibition center generally has a floor height of 12-18 meters, so deploying base stations at the top with such a high floor height may have certain problems, as the base stations have certain inclination requirements.
2、 UWB positioning solution for exhibition center
3.1 Scheme Introduction
The personnel positioning management system solution for the exhibition center adopts UWB technology. By setting up a limited number of positioning base stations in the exhibition area, it can accurately locate the positions of employees who have already worn positioning tags in real time. With zero delay, the location information of employees will be accurately reflected in the factory control center, facilitating real-time employee positioning, on duty monitoring, and attendance management. The highest accuracy reaches the level of 10 centimeters, but due to the large number of booths in the exhibition center, and some booths reaching a height of up to 6 meters, the signal obstruction is very serious. The popular UWB positioning technology has the problem of NLOS line of sight positioning, so high-precision position information cannot be obtained.
Tengdong Information's UWB positioning technology has improved ordinary UWB positioning methods, greatly improving the positioning accuracy of the exhibition center, with an average accuracy of about 1 meter.

Staff and security personnel in the exhibition hall
5、 Composition of UWB positioning system
1) UWB positioning base station covering the exhibition hall
2) Personnel positioning label
3) Exhibition hall map and real-time location display 2D/3D software platform
6、 Working principle
After receiving the tag signal, the positioning base station calculates and transmits the data to the positioning server. The positioning engine software in the positioning server displays the location of personnel and displays the specific location through an electronic map. Management personnel use real-time maps to display personnel locations for personnel scheduling and management.

7、 Main functions
1) Real time location display: The map server displays the actual location information of all employees and security guards in real time.
2) Historical trajectory data playback: The location server stores historical location data and can revisit and query the dynamic location of personnel in the exhibition center at key time nodes.
3) Security zone alarm: Electronic barriers are set up in the work area, alarm area, and restricted area for staff. Once entered, corresponding levels of alarms are triggered.
4) Personnel attendance management: One click search for real-time personnel quantity and commuting time at the exhibition center.
5) Mobile query: on-site inquiry of the exhibition area, which can be carried out by handheld tablets or mobile phones within the exhibition center, and the on-site exhibition situation can be displayed based on the map of the mobile phone or tablet.
6) Big data analysis of exhibition centers: comprehensive analysis of personnel distribution heatmap analysis, personnel activity mileage statistics, etc.
7) Video and personnel positioning linkage: Camera tracking can be performed based on location coordinates to display current video information.
