Embodiment 1

[0056] Embodiment 1. Single point reset - wireless charging IP67 smart watch

[0057] figure 1 It is a fully-sealed smart watch with a non-contact case that supports IP67 waterproof and dustproof, and has wireless charging. in:

[0058] 101 is an antenna coil for wireless charging, which is arranged inside the watch casing. 102 is a wireless charging circuit supporting the Qi standard. 103 is a rechargeable polymer battery, and Vb is the voltage detection terminal of the polymer battery. 106 is a power supply circuit, which changes the power supply of 103 to the requirements required by 107. 107 is the smart watch circuit based on bluetooth. 104 is an overcharge signal generating circuit, Vb is the polymer battery voltage detection value from 102 , Sd is an undervoltage protection signal, and Su is an overcharge containment signal. 105 is a reset circuit, where S 1 It is the reset signal output terminal.

Embodiment 2

[0068] Embodiment 2, multi-point reset - VR / AR / MR system with multiple sensors

[0069] image 3 is the block diagram of the system. Figure 4 is the reset timing diagram of the system.

[0070] In this embodiment, the similarity with Embodiment 1 will not be repeated, and its differences are:

[0071] System reset is divided into 4 steps:

[0072] 1. 311 can reset the reset circuit. This is the circuit that needs to be reset first when the system is reset, for example it is a 9-axis sensor, which is used to sense the position and motion status of the system.

[0073] 2. 309 is divided into power supply 2, which is the reset step of 310 application circuit 2, and it requires reset after 311.

[0074] 3. 307 is divided into power supply 1, which is the reset step of 310 application circuit 1, and it requires reset after 309.

[0075] 4. 306 total power supply, which is the last circuit accessed in the system.

[0076] The above four reset steps are implemented through th...

Abstract

The present invention relates to a method and system for overcharging reset, using the overcharging signal generated by the charging circuit when the rechargeable battery is fully charged, and further generating single or multiple reset signals to reset the main power supply, branch Power supply and resettable circuit, so as to achieve the method of not needing an external reset switch, reset through "overcharge", and restore the state before reset after reset. This method is applied to wearable devices with wireless charging. When charging each time, a reset is generated, or when the device crashes and the watchdog fails, it can be woken up after charging once, which is conducive to improving the reliability of the device. It is beneficial to make the product into a fully closed and non-contact form.

Description

technical field [0001] The invention relates to the field of information technology, in particular to rechargeable technology, in particular to the technology of wearable devices including wireless charging. Background technique [0002] The so-called "reset" means to restore the initial state on the circuit or program. Including power-on reset, power-off reset and partial reset, such as resetting one or several chips, and resetting one or several local power supplies. [0003] Existing reset techniques include "manual switching method" and "watchdog feeding method". [0004] The so-called "manual switch method" is to reset by manually starting the reset switch; the so-called "watchdog feeding dog method" means that the watchdog does not trigger the reset signal by "feeding the dog". If the "feed dog" pulse is not obtained within the specified time, the watchdog starts a reset signal. [0005] Both of the above techniques have their drawbacks: [0006] The "manual switch...
