1. System Overview
The overall solution of Xindao Intelligent’s personnel positioning system based on enterprise/factory adopts the most advanced ZigBee wireless technology in China. The whole solution is composed of the following parts:
1) Hardware: It consists of monitoring server, network switch, control unit, reader base station, and active positioning card.
2) Software: It consists of positioning platform, 3D real-world electronic map, middle-level application, and database.
Through the implementation of Xindao’s intelligent wireless real-time positioning system, functions such as precise positioning, real-time tracking, historical trajectory playback, area access, mobile attendance, and security inspections can be realized, and the highest positioning accuracy can reach 3 meters. Through the application of this system, the personnel of the enterprise and the temporary personnel entering and leaving the factory can be effectively managed, thereby improving the management efficiency of the factory personnel.
2. Principles of System Design
First, according to the specific environment of different companies, deploy a certain number of card reader base stations in the factory area to enable full coverage of the network signal in the factory, and then consider wearing a fate location card for the personnel who need to be supervised in the factory. Once the person wearing the identification card enters the factory area, the card reader base station receives the information transmitted by the positioning card in real time, and uploads the information to the base station control unit, and the control unit uploads it to the server host. The wireless positioning platform system can determine the real-time position of the personnel through software processing based on the positioning card information uploaded by the card reader base station, and display it on the electronic map as a personnel icon + name, and can track the personnel in real time.
The system records the position information of the personnel once in a fixed time, and replays the historical trajectory in the manner of personnel + line segment.
The system can set the access authority of the factory area, place the card reader base station in the restricted area, and the system software sets the access authority of the area. When personnel enter the area without authorization, the system will alarm.
The system can also expand the attendance system to realize the integration of the positioning system and the attendance system. And can be integrated with the factory’s access control system.

4. Main functions of the system
4.1 Real-time monitoring
Real-time map monitoring includes area display and device display. When the area is displayed, the map is divided into several areas for real-time monitoring. The display content includes the name of the area, the number of personnel, etc.; when the device is displayed, it displays the conditions of all the devices in the factory area, and can locate the device, view information, view links, and modify the device. operate.
4.2 Comprehensive management of employees
Employee comprehensive management includes: employee information management, shift management, team management, department management, job management, job management,
Personnel information management, shift management, personnel query, historical information query, information modification, information deletion, and personnel area access.
4.3 Personnel query
Personnel information query, personnel track query.
4.4 Map monitoring
Show all personnel distribution and equipment distribution. When the personnel is displayed, the personnel icon and the name are displayed. Click the personnel icon to further view the detailed information and trajectory of the personnel; when the equipment is displayed, you can view the equipment information, link, personnel list, etc.
4.5 Area Management
Including area addition, deletion, modification, access settings, etc., it can count the time and stay time of personnel entering and leaving the area, whether they enter the workshop at the specified time, and whether they leave the workshop at the specified time, so as to grasp the activities of the personnel.
4.6 Personnel positioning
The system has a personnel positioning function. When a certain person needs to be located, the personnel information can be searched in the personnel query function of the system, and the positioning can be realized by clicking the positioning button.
4.7 Query and Playback of Personnel History Track
Personnel management has the function of querying personnel historical tracks. There are two display modes. One is to list the area that the personnel has passed through during the query period, and the other is to replay the historical track of the personnel. When you click on the personnel’s historical track After the historical trajectory is played back, the icon of the person is displayed on the map and the trajectory route is automatically drawn.
4.8 Equipment low power, fault management function
Including positioning card low power, positioning card failure, card reader base station failure, base station control unit failure management functions.
4.9 Statistical analysis
Statistical analysis includes: card issuance statistics, workshop access statistics, etc.
4.10 User Management
User management, system administrator users and monitoring users can be set. System administrators can set equipment and area operations. Monitoring users can only view related information and cannot modify related settings.
