1. Demand background
There are three characteristics of tourist attractions: First, the area of the scenic area is large, the second is crowded and mixed, and the third is the weak mobile phone signal. This feature makes it easy for people to get lost in the scenic area, which can lead to danger. The blind area of mobile phone communication signals makes it more difficult to solve the problem, and requires more manpower and material resources.
According to the characteristics of tourist attractions, Guangzhou Zhongzhi Internet of Things Technology Co., Ltd. has launched the “Scenic Area Personnel Positioning Management System” (hereinafter referred to as the “system”). It has the characteristics of easy installation, seamless transition, low investment, and obvious results. The system can clearly Locate the instant location of tourists. When tourists enter the dangerous area, the system will actively remind and alert, and can quickly and effectively retrieve them in the event of missing persons.
2. System description
Figure 1 System usage schematic
As shown in Figure 1, the scenic personnel location management system is composed of three parts: background monitoring, entry and exit identification, and activity process positioning.
Back-end monitoring refers to the remote monitoring of data information such as the operation of various equipment in the scenic spot and the location of tourists through the back-end software system, server and the Internet.
Entry and exit identification refers to identification through the entrance and exit gates and personnel cards. The personnel cards have built-in RFID chips and are compatible with high-frequency RFID card functions. After ticket issuance, you can directly swipe the gates to enter the scenic area, and you can block the personnel when you exit the scenic area. The gate machine is reclaimed and departed.
Activity process positioning refers to the activities of tourists wearing personnel stuck in the scenic area. When they pass by the base stations located in key sections of the scenic area and special locations, they can be detected, and route information will be formed, and corresponding alarm signals can be issued when entering the dangerous area.
Through the close cooperation of the three major parts, the system constitutes the intelligent positioning and recognition management of the entire process of tourists from entering the scenic spot to leaving the scenic spot.
Three, equipment introduction
1. Personnel Card
Figure 2 Schematic diagram of personnel card
Every tourist must carry a personnel card when entering the scenic spot. The system will also write the tourist’s mobile phone number into the personnel card when the card is issued. After the card is issued successfully, the personnel card will be in working state and send signals at intervals. When passing through the base station, The base station can obtain the information of the visitors with the card. When passing the electronic fence base station, the indicator light on the personnel card will keep flashing to remind the visitors of the danger ahead. At the same time, the alarm information can also be obtained in the background.
Finally, when the tourist leaves the scenic spot, the personnel card is inserted into the turnstile and it goes to sleep after being recovered to save power.
2. Base Station
Figure 3 Schematic diagram of base station
Considering the portability of installation, the base station only needs 220V power supply, and it is generally installed on a video monitoring pole, which is convenient for installation and access to electricity, and secondly, it can be combined with video monitoring to check the current situation. The base station is connected to the database via GPRS. The distance for the base station to receive the personnel card is within 100 meters, which is related to the on-site environment.
The method of the sub-base station is to solve the problem that there is no GPRS signal at the location of the sub-base station, and the distance between the sub-base station and the base station is 300 to 500 meters, and the information received by the sub-base station is transmitted to the database through the parent base station.
3. Card Issuer

The card issuer is designed as a USB connection desktop type, used for the ticket window visitors to purchase tickets, the ticket seller will give the tourist personnel card, and through the card issuer to write relevant information (such as mobile phone number) into the issued personnel card.
4. Handheld
Figure 5 Schematic diagram of the handheld
When a tourist is missing, the manager locates the search area based on the tourist’s trajectory, and then carries the handheld to the search site to find it. The search range of the handheld is within 80 meters. Enter the identity of the tourist to conduct a targeted search. Closer to the personnel card worn by tourists, the faster the handset sounds, the closer you are to the search target. The appearance is shown in Figure 5.
Fourth, the software effect
Figure 6 System login interface
Managers can remotely view the real-time situation of the entire scenic spot through the background system.
Figure 7 Schematic diagram of the information input interface
As shown in Figure 7, when a tourist buys a ticket, the conductor can enter information such as the tourist’s identity certificate and contact phone number. This information can facilitate the identity of the tourist during the entire tour and the advance reservation of required services.
Figure 8 Schematic diagram of trajectory positioning
As shown in Figure 8, when a tourist is missing, the administrator can query the tourist’s recent trajectory and the last disappearing position through the system, which helps the administrator to search and rescue quickly.
Five, search APP software
