FIG1 is a flow chart of a wearable body sign monitoring method provided by an embodiment of the present invention. The wearable body sign monitoring method is applied to a wearable body sign monitoring device. The method specifically includes the following steps:

Step S201, collecting the user's vital signs and current environment information.

Among them, the vital signs signals include: pulse signals, heart rate signals, body temperature signals and expression images.

It should be understood that the wearable body sign monitoring device is provided with multiple sensors, such as a sensor for collecting pulse signals, a sensor for collecting heart rate signals, a sensor for collecting body temperature, and an image acquisition device (such as a camera) for collecting expression images.

It is understandable that the wearable body vital sign monitoring device can be integrated or distributed, and no specific limitation is made here.

As an implementation method, the current environmental information can be collected by an environmental sensor installed on a wearable body sign monitoring device, or by a camera. No specific limitation is given here. For example, the current environmental information can be light intensity, humidity, temperature, etc.

Step S202: Generate the user's current state information according to the vital sign signal and the current environment information.

It should be noted that the status information is a numerical value, not a string.

As an implementation method, step S202 includes: generating sub-state information based on the pulse signal, the heart rate signal and the body temperature signal; identifying the expression tag corresponding to the expression image; querying the expression value corresponding to the expression tag; and generating the user's current state information based on the sub-state information, the expression value and the current environmental information.

It should be understood that the sub-state information is a numerical value.

It can be understood that in this embodiment, the user's current physical state is monitored by pulse, heart rate and body temperature, and the user's current state is further integrated in the form of expression images to improve the recognition accuracy, so that the user's current mental state can be better predicted.

Optionally, sub-state information is generated according to the pulse signal, the heart rate signal and the body temperature signal, including: generating a pulse rate value according to the pulse signal; generating a heart rate value according to the heart rate signal; generating a body temperature change value according to the body temperature signal; generating sub-state information according to the pulse rate value, the heart rate value and the body temperature change value, the sub-state information being a numerical value.

It is understandable that by converting the pulse signal, the heart rate signal and the body temperature signal into numerical values, multiple numerical values are processed to obtain a sub-state information, which is used to describe a current physical condition of the user.

Optionally, identifying the expression label corresponding to the expression image includes: matching the expression label corresponding to the expression image from a database, wherein a plurality of expression labels are pre-configured in the database, and the expression labels include a first label indicating joy, a second label indicating anger, a third label indicating sadness, a fourth label indicating fear, a fifth label indicating surprise, a sixth label indicating disgust, and a seventh label indicating no expression.

That is to say, the present invention pre-configures a database in the wearable body vital sign monitoring device, and the database is used to store expression tags.

It is understandable that by querying expression tags from the database, expression recognition can be performed quickly, processing resources can be saved, and database queries can also be completed on wearable body vital signs monitoring devices.

It should be noted that the expression tags in the database can be updated dynamically or periodically, and no specific limitation is made here.

Among them, the first label corresponds to a first expression value, the second label corresponds to a second expression value, the third label corresponds to a third expression value, the fourth label corresponds to a fourth expression value, the fifth label corresponds to a fifth expression value, the sixth label corresponds to a sixth expression value, and the seventh label corresponds to a seventh expression value.

For example, assuming that the seventh expression value is 0, the first expression value is 1, the second expression value is 0.8, the third expression value is 0.5, the fourth expression value is 0.4, the fifth expression value is 0.3, and the sixth expression value is 0.1.

Optionally, the user's current state information is generated based on the sub-state information, the expression value and the current environment information, including: calculating the sub-state value corresponding to the sub-state information; processing the sub-state value and the expression value to generate the user's current initial state information; generating the user's current state information based on the current environment information and the initial state information.

The state information satisfies:

Wherein, SI represents the state information, α is the weight coefficient of the sub-state value, S is the sub-state value, β is the weight coefficient of the expression value, I is the expression value, and E is the current environment information. is the weight coefficient of the current environment information.

Optionally, α＜β,

For example, α is 0.3, β is 0.5, is 0.2.

It can be understood that by combining α, β, By setting different weights, we can improve the accuracy of predicting the user's mental state and strengthen the degree to which expressions reflect the mental state, so as to improve the accuracy of prediction.

It should be understood that the environmental information can also be converted into numerical values, and the specific conversion process is not specifically limited here.

For example, environmental information can be converted with "1" as the standard, and different numbers can be used to represent the different effects of different environments on users. For example, at 25 degrees, the temperature corresponding value can be considered to be 1, while for temperatures above 25 degrees, it can be greater than 1, and for temperatures below 25 degrees, it can be less than 1, and even when the temperature reaches below zero, its corresponding value can be a negative number. No specific limitation is made here.

It should be understood that the collection of environmental information in the present invention is used to strengthen the prediction of the user's mental state, so as to predict the impact of different physical signs in different environments on the user's mental state.

Step S203: determine whether the state value of the state information is within a threshold range.

It is understandable that the specific value of the threshold range can be set according to actual conditions, and the present invention does not make any specific limitation.

Step S204: if not, send a warning message to the user terminal, and the user terminal establishes an Internet of Things connection with the wearable body vital sign monitoring device.

It is understandable that the user terminal can be the user's smart phone or other monitoring terminals, and no specific limitation is made here.

In addition, the warning information mentioned above can be a text message, or a warning message made by wearing a body sign monitoring device to emit an alarm sound. Here, no specific limitation is made.

It can be understood that the user terminal mentioned in the present invention can be a user wearing the wearable body sign monitoring device, or a user designated by the user wearing the wearable body sign monitoring device.

To summarize, the wearable body vital sign monitoring method provided by the present invention collects the user's vital sign signals and current environmental information; generates the user's current status information based on the vital sign signals and the current environmental information; determines whether the status value of the status information is within a threshold range; if not, sends a warning message to the user terminal, so that the user's mental state information can be generated from the monitored vital sign signals.
