1. Demand background
Counting the flow of people in the exhibition hall allows managers to formulate marketing strategies more scientifically, understand and adjust design styles, and obtain application data such as consumer psychology. Guangzhou Zhongzhi Internet of Things uses active RFID technology to implement a low-cost exhibition hall traffic statistics system to improve scientific and reliable data for exhibitors and organizers.
2. System introduction
1. System topology diagram
Figure 1 System topology diagram
The system topological chart is shown as in Fig. 1. Exhibitors register at the front desk before entering the venue, enter their identity information such as age and telephone number, and the staff can issue electronic visit cards to exhibitors. Each booth can be installed with a positioning base station. The positioning base station covers a spherical area with a radius of 3 to 5 meters. When exhibitors pass by and stay on the booth, they will be recognized by the positioning base station, and the data will be uploaded to the back-end system through the WIFI network. Managers can access the system server through a computer/mobile phone, query data, and do corresponding statistical analysis.
2. Locating the base station
Figure 2 Positioning the base station
As shown in Figure 2, the positioning base station is installed in the booth and can be installed through a bracket or ceiling. The positioning base station receives the signal issued by the electronic visit card in the booth and uploads it to the background system through the WIFI network. The appearance size of the monitoring base station: 204mm (diameter) × 52mm (height).
3. Electronic visit card
Figure 3 Electronic visit card
As shown in Figure 3, the electronic visit card can be worn alone or placed in a traditional paper visit card. When exhibitors enter the booth with an electronic visit card, they will send their globally unique ID number to positioning themselves. The appearance size of the electronic visiting card: 86mm×54mm×5.5mm.
4. Active card issuer
Figure 4 Active card issuer
As shown in Figure 4, the card issuer is connected to the computer through the USB interface, reads the ID number of the electronic exhibitor badge through non-contact, enters the relevant information of the visitors into the system, and binds with the ID number of the electronic exhibitor badge to complete the card issuance . The card issuer can reissue the e-exhibition card, which is convenient for repeated use. Appearance size: 145mm×93mm×35mm.
3. Software introduction
1. Login interface
Figure 5 Login interface
The system adopts the B/S architecture, and the administrator logs in to the system on the browser through the account and password, and performs operations such as label entry, base station configuration, data query, and statistical records.
2. Information Entry
Figure 6 Information Entry
As shown in Figure 6, the staff enters the exhibitor information (name, contact number, etc.) through the web background system, and uniquely binds it with the ID number of the electronic exhibitor badge.
3. Statistical analysis
