The signal processor is arranged on the seat cushion, and the backrest sensor array on the backrest is connected to the signal processor through a lead.

Hereinafter, the content related to the acquisition and processing of data by the processor will be described in this embodiment.

In this embodiment, the seat cushion pressure signal is a signal output from one or more pressure sensors within a period of time, and the backrest pressure signal is a signal output from one or more pressure sensors within a period of time . In this embodiment, when the processor detects that the pressure value of the pressure sensor suddenly changes more than the threshold, it acquires a pressure signal that lasts for a period of time from that moment, and the data in the duration includes at least one movement data and body One heartbeat data and one breathing data when relatively calm after exercise.

In some embodiments, the signals output by the one or more pressure sensors may be signals detected by a corresponding number of one or more pressure sensors, in other words, no pressure signals are detected by other pressure sensors. For example, the seat cushion sensor array contains 200X200 pressure sensors, each sensor is set with a number, when the user sits on the seat cushion, some of the pressure sensors sense the pressure signal and output To the processor, the remaining pressure sensors did not detect a pressure signal. Of course, those skilled in the art should understand that the number of pressure sensors here is only an example, and more or fewer sensors can be provided in actual situations.

In some embodiments, the signal output by the one or more pressure sensors may be a signal output by a part of the pressure sensors among the sensors that sense the pressure signal. For example, the pressure signal in each sensor is preprocessed, the data below the threshold is filtered out as noise data, and the pressure signal is output when the pressure signal is detected to be higher than the threshold.

In this embodiment, the signal processor 05 is configured to extract a first body movement data and a first heartbeat data of the user according to the seat cushion pressure signal, and extract a second body movement data of the user according to the backrest pressure signal. Body movement data, a second heartbeat data, and a breathing data, wherein the first heartbeat data and the second heartbeat data have the same frequency.

In the foregoing embodiment, the backrest detects breathing data more accurately than the seat cushion, because the user's heartbeat behavior exerts greater pressure on the backrest, and the detection result is relatively more accurate.

For the backrest or the seat cushion, the same pressure sensor can detect the user’s body movement, heartbeat, and breathing data at the same time. The body movement, heartbeat and breathing data are extracted from the pressure signal.

For example, in general, when the user sits on the seat, the relative change of the body movement data at different moments is relatively large in the first time period, and the heartbeat data is relatively regular. When the user sits firmly, the body movement data at different moments The relative change range of is small, and even the change range is based on tending to 0. At this time, it is easier to detect the heartbeat data. Generally, the greater the variation range, the greater the fluctuation range of the data, and the smaller the variation range, the smaller the fluctuation range of the data. The reference value of the variation range and the fluctuation range may be an average value in a period of data, or a series of data in a period of time.

Based on the above-mentioned application scenarios, in some embodiments of the present application, the above-mentioned technical solution advancement one includes: the signal processor is configured to detect that the first body movement data and the second body movement data are lower than a first threshold, The frequency of the first heartbeat data is extracted from the seat cushion pressure signal; and after the signal with the same frequency as the first heartbeat data is filtered from the backrest pressure signal, the remaining signal in the backrest pressure signal is used as the breathing signal Extract the breath data.

It can be seen from the above embodiment that the signal processor is configured to detect that the first body movement data and the second body movement data are lower than the first threshold, indicating that the body movement change range is small, and the pressure value data change is also Relatively stable, the heartbeat data is relatively accurate since then. In order to improve the accuracy and timeliness of data extraction, the frequency of the first heartbeat data is extracted from the seat cushion pressure signal, and the backrest pressure signal is filtered with the same frequency as the first heartbeat data; the backrest The remaining signal in the pressure signal is used as a breathing signal to extract the breathing data. The above technical solutions can separate different types of signals from a section of pressure signals relatively accurately and in time.

In one embodiment, the signal processor detects the pressure value of each sensor on the seat cushion sensor array 03, and when the pressure value of each sensor has a fluctuation range less than a second within a predetermined time When the threshold is reached, it is determined that the first body movement data is lower than the first threshold; the signal processor also detects the pressure value of each sensor on the backrest sensor array, when the pressure value of each sensor is at When the fluctuation range within the predetermined time is less than a third threshold, it is determined that the second body movement data is lower than the first threshold.

The second threshold and the third threshold may be the same or different, and the different second threshold and the third threshold are both within a preset range.

It can be seen that the user's body movement data is detected by the seat cushion sensor array 03 and the backrest sensor array 04, and the processor integrates the detected results of the seat cushion sensor array 03 and the backrest sensor array 04 Determine body movement data; the user's heartbeat data is detected by the seat cushion sensor array 03 and the backrest sensor array 04. The processor integrates the detection results of the seat cushion sensor array 03 and the backrest sensor array 04 to determine the user's current heartbeat data. Can improve the accuracy of data detection results.

Further, before separating the aforementioned body motion data, heartbeat data, and respiration data from the data fed back by the sensor, it is necessary to determine whether the user is sitting on the seat cushion, so as to prevent some objects from being placed on the seat to activate the application The corresponding product features of the technical solution.

In this embodiment, the signal processor is configured to determine whether the pressure signal generated by at least one pressure sensor in the seat cushion pressure sensor array exceeds a fourth threshold, and if so, it is determined that a user is sitting on the seat And further extract the first body movement data, the first heartbeat data, the second body movement data, the second heartbeat data, and the breathing data.

The fourth threshold may be preset by the user. For example, the driver's seat cushion is generally set to the range of adult weight, and the child seat is generally set to the range of child's weight.

In one or more of the above embodiments, the signal processor determines the user’s different types according to the first body movement data and the second body movement data, the respiration data and the first heartbeat data and the second heartbeat data. Behavior characteristics, and output different control commands according to the different types of behavior characteristics.

This control command has different command content in different scenarios. In many scenarios, the control command can be at least a prompt information command, or a command to control some equipment to change the working mode. Among them, changing the working mode can be to start the work or stop the work, or switch to different work states after starting the work.

The above behavior data is used to output different control commands in different scenarios.

In some scenarios, the seat is a car seat cushion with a backrest, a home cushion with a backrest, a sofa with a backrest, or a bed with a backrest;

The signal processor is configured to determine the user's emotional level according to the first heartbeat data, the second heartbeat data, and the breathing data; and output a control signal to a preset external device with a playback function according to the emotional level to make the The external device plays a predetermined type of music, or outputs a control signal to the external alarm device according to the emotional level to make the alarm device output prompt information. For example, control the speaker to output soft music when emotional, and control the speaker to output rock music when the mood is low. For example, when emotional, the smart robot is controlled to have a dialogue with the user, and the smart robot acquires the user based on the dialogue with the user. Listening to music preferences output favorite types of music or favorite specific tracks. For example, when the seat is used for a patient, when judging that the patient is emotionally excited, it outputs prompt information to inform the nurse to the nurse-side device. The above-mentioned embodiment can also control the mobile phone terminal to automatically establish communication with the third party and notify the alarm according to the emotional level.

In other scenarios, the signal processor is also configured to determine the user's mental state based on the heartbeat data and the breathing data, and if the mental state is about to fall asleep or has fallen asleep, output a control signal to an external device to Switch the working mode of the external device. The mental state includes at least a state of excitement, a state of peace, a state of about to fall asleep, and a state of already falling asleep. If the seat is a car seat cushion, when the user is about to enter the sleep state, switch the vehicle to enter the automatic driving mode, or switch the vehicle to emergency sideways, or switch the airbag of the vehicle from non-working state to working state, or start the player to output a warning Reminder information, such as reminding passengers or drivers to pay attention to safety and not to take a nap.

For example, if the seat is a sofa, when the user is about to enter the sleep state, the TV that is controlled to be turned on is automatically turned off.

In other scenarios, the signal processor is further configured to output a control signal to an external device according to the body movement characteristics of the first body movement data and the second body movement data to make the external device output prompt information. For example, when a car is driving on a bumpy road, there is relative motion between the user and the seat cushion. The sensor detects the user's motion and provides it to the signal processor. The signal processor recognizes the bumpy state and outputs a voice announcement to the speaker. , If please sit firmly and support.
