Description

Technical Field

[0001] The present invention belongs to the technical field of health monitoring, and in particular relates to a non-contact physiological sign integrated monitoring device. Background Art

[0002] Heart rate, respiratory rate, and body temperature are important physiological indicators of the human body. Heart rate and body temperature can be measured by contact instruments such as electrocardiograms and thermometers, while respiratory rate can be measured manually. However, these methods require contact with human skin, which may cause skin irritation or discomfort to some patients who need to be monitored for a long time.

[0003] As for body temperature, thermal imagers can be used to measure body temperature without touching the person being tested, but the images they obtain have problems such as poor resolution and blurred details, which makes it difficult to segment the face from the surrounding environment. To avoid false detection, a method has emerged that uses deep learning technology to fuse ordinary RGB videos with corresponding infrared videos to simultaneously identify the body temperatures of multiple subjects.

[0004] In addition, with the help of millimeter wave radar, frequency modulated continuous wave (FMCW) signals are actively transmitted, and echo signals caused by displacement changes of the heart or chest cavity are received. The breathing and heart rate values ​​can be obtained by using the principle that the phase of the echo signal is proportional to the distance change, and then through signal processing and filtering algorithms.

[0005] However, most of the methods proposed above remain at the laboratory stage and have not achieved a high degree of integration. In addition, due to the dispersion of equipment, it is difficult to automatically monitor targets in multiple directions. Summary of the invention

Figure 1 It is a schematic diagram of the internal structure of a non-contact integrated physiological sign monitoring device disclosed in an embodiment of the present invention. Figure 2 The figure is a schematic diagram of the external structure of a non-contact integrated physiological sign monitoring device disclosed in an embodiment of the present invention.

Figure 6 The invention is a schematic structural diagram of a control unit of a rotation module of a non-contact integrated physiological sign monitoring device disclosed in an embodiment of the invention.

[0058] like Figure 1 As shown, the non-contact physiological sign integrated monitoring device includes a main housing 1, a radar acquisition module, a first processing module, a second processing module, a camera module, a personnel monitoring module, a rotating module, a power supply module and a base 2;

[0059] The radar acquisition module, the first processing module, the second processing module, the camera module, the personnel monitoring module, the rotation module and the power supply module are all fixed inside the main housing;

[0060] The radar acquisition module is electrically connected to the first processing module, and is used to collect radar signals and send the radar signals to the first processing module;

[0061] It should be noted that the above-mentioned radar acquisition module is a development board of an integrated millimeter-wave radar, for example, TI's IWR6843 radar evaluation board can be used, which uses a single-chip 60GHz to 64GHz smart millimeter-wave sensor with an integrated packaged antenna, which is not limited in the embodiment of the present invention.

[0062] The first processing module is electrically connected to the second processing module, and is used to process the radar signal to obtain a respiratory monitoring information set, and send the respiratory monitoring information set to the second processing module; the respiratory monitoring information set includes a plurality of respiratory monitoring information; the respiratory monitoring information includes a respiratory rate value and a heart rate value;

[0063] It should be noted that the first processing module is an FPGA development board, which is connected to the radar acquisition module through a serial port to obtain radar signals. The function of processing the radar signal to obtain a set of respiratory monitoring information is realized by an onboard FPGA chip, which is a prior art and will not be described in detail.

[0064] It should be noted that each respiratory monitoring information in the above respiratory monitoring information set corresponds to one person to be monitored.

[0065] The camera module is electrically connected to the second processing module, and is used to collect video information and send it to the second processing module; the video information includes RGB video and infrared video;

[0066] like Figure 3 As shown, the camera module includes a color camera and an infrared camera;

[0067] The color camera is electrically connected to the second processing module, and is used to collect the RGB video and send the RGB video to the second processing module;

[0068] The infrared camera is electrically connected to the second processing module, and is used to collect the infrared video and send the infrared video to the second processing module;

[0069] like Figure 2 As shown, the main housing is provided with a first camera hole 11 and a second camera hole 12; the color camera is fixed behind the first camera hole inside the housing; the infrared camera is fixed behind the second camera hole inside the housing;

[0070] The second processing module is used to process the video information to obtain a target temperature set, and store and display the respiratory monitoring information set and the target temperature set; the target temperature set includes a plurality of facial temperature values;

[0071] It should be noted that each facial temperature value corresponds to the facial temperature of one person to be tested, so the number of elements in the target temperature set is the same as the number of elements in the respiratory monitoring information set.

[0072] Preferably, the second processing module is a single-board computer using a general-purpose processor architecture CPU such as ARM or X86; the single-board computer is provided with an RJ45 interface, an HDMI interface and several USB interfaces, and the main shell is provided with an RJ45 slot, an HDMI slot and a USB slot corresponding to the above interfaces; the above RJ45 interface, HDMI interface and USB interface are electrically connected to the corresponding RJ45 slot, HDMI slot and USB slot, respectively.

[0073] It should be noted that the second processing module may be a Raspberry Pi 4 Model B running a Linux system, which is not limited in the embodiment of the present invention.

[0074] It should be noted that the above processing of video information obtains the target temperature set, and adopts the video infrared image fusion algorithm based on the RFN-Nest model to fuse the infrared video and the ordinary RGB video so that the target body temperature information corresponds to the face. This technology is existing technology and will not be repeated here.

[0075] It should be noted that the second processing module stores the respiratory monitoring information set and the target temperature set in the built-in memory and displays them through charts and the like. This technology is existing technology and will not be described in detail.

[0076] It can be seen that the use of an independent first processing module to process radar signals can improve the real-time performance and speed of radar signal processing, while reducing the computing pressure of the second processing module. In addition, through the RJ45 slot, HDMI slot and USB slot provided on the main shell, the second processing module can be connected to external devices such as network cables, monitors, USB mice and USB keyboards, so that it can be expanded into a complete computer, which is convenient for exporting and remotely transmitting respiratory monitoring information sets and target temperature sets, and displaying the two on an external display. In addition, since the above-mentioned external devices do not need to be carried together with the non-contact physiological sign integrated monitoring device, the portability of the device is improved.

[0077] Preferably, the radar acquisition module is located behind the first processing module and the second processing module;

[0078] It should be noted that metal structures such as vias, wiring, and shielding layers on the radar acquisition module will interfere with the transmission of electromagnetic waves. Placing the radar acquisition module behind the first processing module and the second processing module so that the radar acquisition module is close to the person to be detected can avoid interference of the PCB boards of the first processing module and the second processing module on the radar signal and improve monitoring accuracy.

[0079] Preferably, the main shell is made of hard plastic, which reduces weight while avoiding radar signal distortion caused by electromagnetic wave interference from metal or magnetic materials, thereby improving monitoring accuracy.

[0080] Preferably, the camera module is located directly above the radar acquisition module.

[0081] It should be noted that by placing the camera module directly above the radar acquisition module, both can be aimed at the person to be detected at the same time, thereby improving the monitoring accuracy and expanding the field of view of the camera module and the monitoring range.

[0082] The personnel monitoring module is electrically connected to the rotation module, and is used to output position information and send the position information to the rotation module; the position information includes N+2 human presence signals; N is an integer greater than 1;

[0083] It should be noted that each human presence signal indicates whether there is a person in the corresponding direction through high and low levels. For example, when the level is high, it means that there is a person in the corresponding direction, otherwise it means that there is no person in the corresponding direction, which is not limited in the embodiment of the present invention.

[0084] The personnel monitoring module includes a first sensor, a second sensor and N auxiliary sensors;

[0085] It should be noted that the first sensor, the second sensor and the N auxiliary sensors each output a human presence signal;

[0086] The first sensor, the second sensor and the auxiliary sensor are all human presence sensors and are fixedly arranged at the same height in the main housing;

[0087] The first sensor and the second sensor are symmetrically arranged on both sides of the radar acquisition module, and are respectively used to monitor whether there are people on both sides of the radar acquisition module.

[0088] The monitoring ranges of the first sensor, the second sensor and the N auxiliary sensors together cover a 360° circumferential monitoring space.

[0089] Take N as 1 as an example, Figure 4As shown, the monitoring angles of the first sensor 1, the second sensor 2 and the auxiliary sensor 3 are all 120°, which can completely cover the surrounding 360° space.

[0090] It should be noted that the above-mentioned human sensor can adopt the HLK-LD1040 module of Hailingke, which is a motion sensing module designed based on the X-band radar chip, with a size of 15×15mm, a center frequency of 10.525GHz, a 3dB bandwidth of 110°±10°, and can sense the presence of human bodies within a range of 120° in front. When a person moves in front, a high-level signal is output through the output terminal; the module has the advantages of anti-interference, small size, good clutter and high-order harmonic suppression, high stability and consistency, and the module initialization time is short, and it has a quick detection mode, which is not limited in the embodiment of the present invention.

[0091] like Figure 2 As shown, the rotating module is used to rotate and fix the main shell above the base, and rotate the main shell according to the orientation information;

[0092] Optional, such as Figure 5 As shown, the rotating module includes a control unit, a stepper motor driving board and a stepper motor;

[0093] The control unit, the stepper motor drive board and the stepper motor are all fixed to the inner bottom of the main housing;

[0094] The control unit is electrically connected to the personnel monitoring module and the stepper motor drive board, and is used to control the stepper motor drive board according to the position information;

[0095] The stepper motor driving board is electrically connected to the stepper motor and is used to drive the stepper motor;

[0096] An output hole is provided at the geometric center of the bottom surface of the main housing; Figure 2 As shown, the output shaft 13 of the stepper motor vertically extends out of the output hole and is fixedly connected to the base.

[0097] The power supply module is electrically connected to the radar acquisition module, the first processing module, the second processing module, the camera module, the personnel monitoring module and the rotation module.

[0098] Preferably, if Figure 6 As shown, the control unit includes a delay subunit and an angle search subunit;

[0099] The delay subunit is a power-off delay relay; the input end of the delay subunit is electrically connected to the personnel monitoring module; the output end of the delay subunit is electrically connected to the angle search subunit;

[0100] Preferably, the preset delay time of the above-mentioned delay subunit is 1 second.

[0101] It should be noted that after the power-off delay relay receives the input signal (i.e. the coil is energized), the execution part (contact) will immediately have an output signal. After the input signal disappears (i.e. the coil is de-energized), the relay needs a certain delay to return to the state before the action.

[0102] It can be seen that by disconnecting the connection with the personnel monitoring module within the preset delay time, the main shell can be prevented from rotating again within this time period, ensuring that there is sufficient time for processing after each rotation of the main shell to obtain accurate respiratory monitoring information and target temperature set.

[0103] The angle search subunit is electrically connected to the stepper motor drive board and is used to obtain a rotation angle value based on the direction information.

[0104] The above-mentioned obtaining of the rotation angle value based on the direction information is to use the direction information to search a preset mapping table to obtain the rotation angle value;

[0105] It should be noted that the above mapping table includes the correspondence between the direction information and the rotation angle. Taking the above three human presence signals as an example, the person in sensor 1 (corresponding to the first human presence signal) and the person in sensor 2 (corresponding to the second human presence signal) are symmetrically arranged on both sides of the radar acquisition module, and the angle with the third person in sensor (corresponding to the third human presence signal) is 120°, and the person in sensor 1, the person in sensor 2 and the person in sensor 3 are arranged clockwise, and the corresponding mapping table is as follows:

[0106]

[0107]

[0108] It should be noted that signal 1 and signal 2 in the above table represent the human presence signals on the left and right sides of the radar acquisition module, respectively, and signal 3 represents the human presence signal output by the auxiliary sensor; in addition, 0 represents a low level, 1 represents a high level, a positive rotation angle represents a clockwise rotation, and vice versa represents a counterclockwise rotation. Each time the delay subunit receives the orientation information of the personnel monitoring module, it immediately sends it to the angle search subunit to obtain the rotation angle value, and further control the rotation of the main shell. When the first human presence signal, the second human presence signal, and the third human presence signal generated by the person in sensor 1, the person in sensor 2, and the person in sensor 3 are low level, low level, and high level, respectively, the rotation angle value is 180°.

[0109] It should be noted that the above-mentioned angle search subunit can be implemented by FPGA, and the preset mapping table is solidified as a lookup table inside the FPGA, which is not limited in the embodiment of the present invention.

[0110] It can be seen that by using the first sensor, the second sensor and the auxiliary sensor to determine the rotation angle value, and rotating the main shell based on the rotation angle value, it is possible to automatically track the person to be monitored in an unattended situation.

[0111] Preferably, a counterweight is provided on the base to increase stability and prevent the main shell from tipping over when rotating.

[0112] Embodiment 2

[0113] See also Figure 7 . Figure 7 It is a schematic diagram of the internal structure of another non-contact physiological sign integrated monitoring device disclosed in an embodiment of the present invention.

[0114] The difference between this embodiment and the first embodiment is that Figure 7 As shown, the above-mentioned non-contact integrated physiological sign monitoring device also includes a wake-up module;

[0115] The radar acquisition module, the first processing module, the second processing module and the camera module automatically enter a low power consumption mode when idle to reduce power consumption when idle;

[0116] The wake-up module is electrically connected to the personnel monitoring module, the radar acquisition module, the first processing module, the second processing module and the camera module, and is used to wake up the radar acquisition module, the first processing module, the second processing module and the camera module after receiving the position information from the personnel monitoring module.

[0117] It can be seen that by using the wake-up module, the power consumption of the device can be reduced during idle time, and when the presence of a person is detected, it can quickly switch to the working state to obtain the respiratory monitoring information and the target temperature set in time.

[0118] Embodiment 3

[0119] The difference between this embodiment and the first embodiment is that the above-mentioned obtaining the rotation angle value based on the direction information includes:

[0120] S1. Number the N auxiliary sensors from 1 to N in order of position.

[0121] It should be noted that the above numbering sequence is clockwise or counterclockwise.

[0122] S2. Set the left sensor as the first sensor, the right sensor as the second sensor, and set the current cycle number M to 0.

[0123] S3, judging the human presence signals corresponding to the left sensor and the right sensor;

[0124] When the human presence signals corresponding to the left sensor and the right sensor are both at high level, the rotation angle value is set to 0, so as to ensure that the person to be detected at the current position is monitored before turning to other directions;

[0125] When the human presence signal corresponding to the left sensor is at a high level and the human presence signal corresponding to the right sensor is at a low level, the rotation angle value is determined to be -(M+1)×360° / (N+2) to ensure that when there is no monitored person on the right side of the radar acquisition module, the person to be detected on the left side is monitored first;

[0126] When the human presence signal corresponding to the left sensor is at a low level and the human presence signal corresponding to the right sensor is at a high level, the rotation angle value is determined to be (M+1)×360° / (N+2) to ensure that when there is no monitored person on the left side of the radar acquisition module, the person to be detected on the right side is monitored first;

[0127] When the human body presence signals corresponding to the left sensor and the right sensor are both at low levels, S4 is executed.

[0128] It should be noted that the low level above indicates that the corresponding sensor detects the presence of a person, and the high level indicates that the corresponding sensor does not detect the presence of a person.

[0129] S4, setting the remaining quantity P to N-2×M, and determining the value of P;

[0130] When P is greater than 1, execute S6;

[0131] When P is equal to 1, the human presence signal corresponding to the auxiliary sensor numbered M+1 is judged; when the human presence signal corresponding to the auxiliary sensor numbered M+1 is at a low level, the rotation angle value is determined to be 0°; when the human presence signal corresponding to the auxiliary sensor numbered M+1 is at a high level, the rotation angle value is determined to be 180°;

[0132] When P is equal to 0, the rotation angle value is determined to be 0.

[0133] S5. Determine that the left sensor is the auxiliary sensor numbered NM, and the right sensor is the auxiliary sensor numbered M.

[0134] S6. Increase the value of M by 1.

[0135] S7. Repeat S3 to S6.

[0136] It can be seen that through the above steps S1 to S7, the monitoring personnel in front of the radar acquisition module can be monitored first, and then gradually expanded to both sides through layer-by-layer judgment, thereby avoiding frequent large-angle movement of the main shell and improving monitoring efficiency.
