VDB1610 Bluetooth anti-self-disassembly positioning watch, the main control chip adopts NRF52832 to realize low-power standby and broadcast information transmission. The positioning scheme can use our VG05 beacon scanning and forwarding watch broadcast information and RSSI, and then use TD05A gateway to cooperate to collect watches Information and report to the background server to parse RSSI to achieve positioning. It can achieve indoor positioning or presence detection with an accuracy of 3~5m, and is recommended for personnel positioning in nursing homes, construction sites, factories, mines, hospitals, prisons, epidemic isolation and other security monitoring occasions. The watch has the SOS button for help function, which can notify the background monitoring personnel in time; the watch is equipped with a heart rate sensor, which periodically returns the heart rate data of the monitored person, which is convenient for the background to set the heart rate alarm range and monitor the health status of the personnel. The strap is made of TPU thickened material, which is firm and durable, and has its own anti-self-disassembly detection. When the strap is cut or disassembled, a message will be sent to the background. The watch is divided into two sub-models with screen and without screen. The watch with a screen has a built-in 0.96" display screen, which can receive and display background notification data, and can also display the working status of different functions of the watch (such as time, heart rate, step counting); the watch without a screen only has a green LED work indication The light flashes quickly when the battery is low to indicate charging. The watch has a built-in vibration sensor, which can remind the wearer when an alarm is triggered or a message is sent; in addition, the built-in acceleration sensor can intelligently switch the Bluetooth broadcast frequency when people are moving and when they are still, to achieve the lowest power consumption standby, and can also be used for step counting (already Implementation), fall detection (need to be customized development) and other functions. The watch uses a magnetic charging interface, and the watch can be charged normally by connecting it to a USB power supply with a USB-to-magnetic cable; the watch has a built-in 750mAh large-capacity rechargeable lithium battery, which can achieve a long standby time of more than 3 months. Features： 1. Anti-disassembly strap: The strap is made of thickened TPU material, which is firm and durable. It has its own anti-self-disassembly detection. When the strap is cut or disassembled, a message will be sent to the background to remind the background management personnel to deal with it in time. 2. Indoor positioning: Bluetooth tamper-evident watch VDB1610 can be used in the Bluetooth positioning system solution. 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 background server for analysis RSSI achieves positioning. It can achieve indoor positioning or presence detection with an accuracy of 3~5m, and is recommended for personnel positioning in nursing homes, construction sites, factories, mines, hospitals, prisons, epidemic isolation and other security monitoring occasions. 3. Heart rate: The watch is equipped with a heart rate sensor, which periodically returns the heart rate data of the monitored person, which is convenient for setting the heart rate alarm range in the background and monitoring the health status of the person. 4 .Screen: The watch is divided into two sub-models with screen and without screen. The watch with a screen has a built-in 0.96" display screen, which can receive and display background notification data, and can also display the working status of different functions of the watch (such as time, heart rate, step counting); the watch without a screen only has a green LED work indication The light flashes quickly when the battery is low to indicate charging. 5 .SOS button: The watch has the SOS button for help function, which can notify the background guardian in time; 6. Charging: The watch uses a magnetic charging interface, and the watch can be charged normally when it is connected to a USB power supply using a USB-to-magnetic cable; 7 .Battery: The watch has a built-in 750mAh large-capacity rechargeable lithium battery, which can achieve a long standby time of more than 3 months. 8 .The watch has a built-in vibration sensor, which can remind the wearer by "vibration" when an alarm is triggered or a message is sent; 9. The watch has a built-in acceleration sensor, which can intelligently switch the Bluetooth broadcast frequency when people are moving and when they are still, to achieve the lowest power consumption standby, and can also be used for pedometer (already implemented), fall detection (customized development required) and other functions.
