1、 Features of anti disassembly Bluetooth wristband

1.1 Anti disassembly watch strapThe strap is made of TPU thickened material, which is sturdy and durable. It comes with anti disassembly detection. When the strap is cut or disassembled, a message will be sent to the backend to remind the backend management personnel to handle it in a timely manner.

1.2 Indoor PositioningThe Bluetooth anti tamper watch VDB1610 can be applied to Bluetooth positioning system solutions. The positioning solution can use our VG05 beacon to scan and forward watch broadcast information and its RSSI, and then use TD05A gateway to collect watch information and report it to the backend server for RSSI analysis to achieve positioning. It can achieve indoor positioning or presence detection with an accuracy of 3-5m, and is recommended for personnel positioning in safety monitoring settings such as nursing homes, construction sites, factories, mines, hospitals, prisons, and epidemic isolation.

1.3 heart rateConfigure a heart rate sensor in the table to periodically transmit heart rate data of the monitored personnel, facilitating the setting of heart rate alarm range in the background and monitoring the health status of personnel.

1.4 screenWatches are divided into two sub models: those with screens and those without screens. The watch with a screen has a built-in 0.96 "display screen that can receive and display background notification data. In addition, it can display the working status of different functions of the watch (such as time, heart rate, and step counting). The watch without a screen only has a green LED working indicator light, which flashes to prompt charging when the battery is low.

1.5 SOS buttonThe watch is equipped with an SOS button for distress, which can promptly notify the background monitoring personnel;

1.6 chargeThe watch uses a magnetic charging interface and can be charged normally by connecting a USB to magnetic cable to a USB power source;

1.7 batteryThe watch is equipped with a 750mAh large capacity rechargeable lithium battery, which can achieve an ultra long standby time of more than 3 months.

1.8 The watch is equipped with a built-in vibration sensor, which can alert the wearer in a "vibration" manner when an alarm is triggered or a message is sent;

1.9 The watch is equipped with an acceleration sensor, which intelligently switches the Bluetooth broadcast frequency between personnel movement and stillness, achieving the lowest power standby. It can also be used for functions such as step counting (already implemented) and fall detection (customized development required).

When charging, the battery level grid will cycle and display. When fully charged, the battery level grid remains unchanged, indicating full charge.

3.5 Heart rate monitoring. After booting up, heart rate monitoring will be performed every 10 minutes for about 20 seconds each time, and the test data will be transmitted to the background.

3.6 Anti disassembly function. When the watch strap is disassembled or cut, the watch will send disassembly information to the backend to remind the monitoring personnel.

3.7 Screen display function. After turning on, HR is displayed in the upper left corner of the screen, where H represents heart rate function and R represents step counting function; The battery level is displayed in the upper right corner of the screen. The heart rate value of the test is displayed in the middle of the first interface. After briefly pressing the button, the step counting function interface is entered, and the current step counting information is displayed in the middle.
