Example 1
One of the purpose of the embodiment of this application is to provide an intelligence wearing equipment, detection that can be accurate whether itself is correctly worn by the real person. Fig. 1 is an internal structure schematic diagram of an intelligent wearable device according to embodiment 1 of the present application, and as shown in fig. 1, the intelligent wearable device at least includes a touch chip, a photosensitive module, a heart rate monitor, an acceleration sensor, a pulse rate monitor, and a main chip. Specifically, the touch chip is used for monitoring a capacitance value; the photosensitive module is used for monitoring the light intensity around the wearing part; the heart rate monitor is used for monitoring a heart rate signal; the acceleration sensor is used for detecting the action within the preset time; the pulse rate monitor is used for monitoring a pulse rate signal; the main chip is used for judging whether the intelligent wearable equipment is worn or not according to the capacitance value, the light intensity, the heart rate signal, the action amount and the pulse rate signal. It should be noted that the main chip is preferably a low power consumption bluetooth chip.
As an example, the heart rate monitor comprises an optical heart rate sensor, and the detection principle of the heart rate signal is as follows: the light emitted to the skin through the capacitor light is received by the photosensitive sensor and converted into an electric signal, and the electric signal is converted into a digital signal, so that the heart rate is calculated according to the light absorption rate of blood.
As an example, the smart wearable device includes a biosensor, which is integrated with the photosensitive module, the heart rate monitor and the pulse rate monitor, and is connected to an analog front-end processing chip, which is connected to the main chip. In addition, the main chip is also respectively connected with the acceleration sensor and the touch chip.
As an example, the smart wearable device further includes a power supply module, the power supply module is connected to the main chip, the power supply module includes a charging terminal, a battery management chip, a battery, and a DC-DC converter, the charging terminal is respectively connected to the battery management chip and the DC-DC converter, the battery management chip is connected to the battery, the battery is connected to the DC-DC converter, and the DC-DC converter is connected to the main chip. In addition, the master chip is further connected to a crystal oscillator of, for example, 32.768KHz, a crystal oscillator of 32MHz, a memory, a bluetooth antenna, and the like, for example, the acceleration sensor communicates with the master chip through an SPI (serial Peripheral interface) protocol, and the memory may also communicate with the master chip through the SPI protocol.
Based on the above content, the working principle that the intelligent wearable device detects whether the intelligent wearable device is worn is as follows: because human tissues have high permittivity, the capacitance value of the touch chip can change when the touch chip is worn, so that when the capacitance value detected by the touch chip reaches a certain threshold value, a touch event is triggered, and a signal is sent to the main chip at the moment; the main chip informs a photosensitive module in the biosensor to detect the light intensity around the wearing part; the photosensitive module transmits the light intensity value to the main chip for judgment, and if the light intensity value is lower than a first threshold value, the main chip informs a heart rate monitor in the biosensor to detect a heart rate signal; the heart rate monitor transmits the detected heart rate signal to the main chip for judgment, and if the heart rate signal is within a first specified range, the main chip informs the acceleration sensor to detect the action within the preset time; the acceleration sensor transmits the detected motion quantity to the main chip for judgment, and if the motion quantity exceeds a second threshold value, the main chip informs a pulse rate monitor in the biosensor to monitor a pulse rate signal; the pulse rate monitor transmits the detected pulse rate signal to the main chip for judgment, and if the pulse rate signal is within a second specified range, the intelligent wearable device is considered to be worn.
As an example, the smart wearable device of the embodiment of the present application may be an apparatus for detecting body functions, and may also be a sleep apparatus, or the like. Preferably, the intelligence wearing equipment of this embodiment is including being used for fixing the ring form part at real person's finger, ring form part is equipped with inside and holds the chamber, and is equipped with towards the uncovered of wearer's finger, biosensor locates inside and holds in the chamber, and run through uncovered in order to laminate with pointing the abdomen, so, when intelligence wearing equipment correctly wears in the finger, uncovered is totally covered by pointing the abdomen, then the photosensitive module among the biosensor can not detect outside light, the light intensity that wears around the position that detects this moment is 0. The acceleration sensor and the main chip are not necessarily provided at a position facing the abdomen of the finger, and for example, the acceleration sensor and/or the main chip may be provided at a position facing the nail of the finger, and are not particularly limited.
Example 2
A second objective of the embodiments of the present application is to provide a wearing detection method for an intelligent wearable device, fig. 2 is a flowchart of a wearing detection method for an intelligent wearable device according to embodiment 2 of the present application, and as shown in fig. 2, the method includes the following steps:
s201: monitoring light intensity around the wearing part when a touch event occurs;
s202: monitoring a heart rate signal if the light intensity is lower than a first threshold;
s203: if the heart rate signal is within a first specified range, detecting the action amount within a preset time;
s204: if the motion quantity exceeds a second threshold value, monitoring a pulse rate signal;
s205: if the pulse rate signal is within the second specified range, the intelligent wearable device is judged to be worn.
Therefore, in the above S201-S205, if any step does not satisfy the condition, it is determined that the smart wearable device is not worn, in other words, it is determined that the smart wearable device is worn only when all the steps satisfy the condition, so that the accuracy of the detection result is improved by the multiple condition determination.

As an example, in step S202, light reflected back through skin tissue is detected by an optical heart rate sensor.
As an example, in step S203, the displacement amounts on the X axis, the Y axis, and the Z axis are detected by the acceleration sensor and added to obtain the motion amount, and for example, it is determined whether the motion amount in the previous minute exceeds the second threshold, and if so, the pulse rate signal is further monitored.
As an example, in step S204, the pulse rate signal is monitored by the photoplethysmography, that is, the photoplethysmography pulse wave signal of the user at each time period is monitored.
According to the content, the embodiment of the application can accurately detect whether the intelligent wearable device is worn correctly by a real person through multiple judgments, so that the aim of improving the accuracy of the detection result is fulfilled.

s301: the capacitance value of the touch chip is increased, and a touch event occurs;
