Intelligent anti-theft bracelet solution development

Smart bracelet development solutions have become more and more mature. Anti-theft bracelets can better prevent the elderly and children from getting lost, making our lives even more convenient. Today I introduce the design of a smart anti-theft bracelet.

The design of this project mainly combines a GPS positioning system with a silicone bracelet, and a terminal with built-in GPS module and mobile communication module. The positioning data obtained by the GPS module is transmitted to the server on the Internet through the mobile communication module. The bracelet adopts a sub-master strap design, has a built-in vibration sensor, and is equipped with dual alarm functions of the master strap and mobile phone. When the sub-ring exceeds the safe range, the master ring will vibrate, and the mobile client will receive an alarm message. Therefore, this is an intelligent positioning bracelet developed through analysis and analysis, which has electronic fence functions, displacement alarm functions, and automatic storage of longitude and latitude coordinates.

system structure

First, we program the GPS module and connect it with the communication module to set the forbidden area on the electronic fence function. When the target walks out of or enters the forbidden area, the positioning terminal will alarm the preset authorization number or alarm the monitoring center, and Return the target's latitude and longitude, moving speed and other data to the control center.

Positioning information and auxiliary information in NMEA format are continuously output through the serial communication port. It adopts the original design of the sub-master tape and dual alarms of the master tape and mobile phone. The sub-ring is outside the safe range.

System function introduction

Electronic fence function: After setting the forbidden area, when the target walks out of or enters the forbidden area, the positioning terminal will alarm the preset authorization number or the monitoring center, and return the target's longitude, latitude, speed and other data to the control center.

Displacement alarm: The device stays in one place stably for a certain period of time, and the alarm will be issued immediately if it exceeds this place.

Overspeed alarm: When the equipment running speed exceeds the set speed, it will alarm immediately.

Automatically save latitude and longitude coordinates: When the locator enters an area without GPS signal, it will automatically send the latitude and longitude coordinates of the last time there was a signal to the authorized number; when entering or exiting the blind zone, there will automatically be a message to remind the location, and the latitude and longitude coordinates will be automatically saved.

Advantages: The master tape adopts original design, built-in vibration sensor, dual alarm for master tape and mobile phone. When the sub-ring exceeds the safe range, the main ring will vibrate, and then the mobile phone client will alarm.

The GPS module and mobile communication module are built into the silicone bracelet. Based on the electronic fence function of the GPS tracker, the center manager sets the terminal driving area. When the terminal exceeds the preset restricted area, an alarm will be automatically sent to the monitoring platform. information and send a short message of cross-area alarm to the supervising mobile phone. We will apply this function to this project, that is, when the sub-ring is far away from the main ring within a certain range, an alarm will be sent to the main ring. At this time, the main ring can query the geographical location of the sub-ring on the Internet terminal.

Summarize:

Based on the basic functions of the GPS positioning system and the bracelet, we combine the two and build a terminal with a built-in GPS module and mobile communication module to achieve dual alarms on the master band and mobile phone. Thus, the warning level and positioning accuracy of the system are improved.
