Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a pressure sensing mat 100 with a prompt function according to a first embodiment of the present invention includes a pad 110, a pressure sensor 120, a temperature sensor 130, a controller 140, an alarm device 150, a reset unit 160, and a wireless communication unit 170.
Specifically, the pad 110 has a supporting function and is subjected to pressure while supporting a human body or other objects having a weight. The pressure sensor 120 is accommodated in the gasket 110 and senses the pressure and the pressure range when the gasket 110 is under pressure.
The temperature sensor 130 is accommodated in the pad 110 and analyzes whether the pressure received by the pad 110 is from the human body when the pressure is received by the pad 110, and it can be understood that the temperature sensor 130 determines whether the pressure received by the pad 110 is from the human body according to whether the detected temperature falls within the normal body temperature range of the human body. In this embodiment, the temperature sensor 130 is connected to the pressure sensor 120, and after the pressure sensor 120 senses that the pad 110 is under pressure, the temperature sensor 130 starts to analyze whether the pressure is from the human body.
The controller 140 is connected to the pressure sensor 120, the temperature sensor 130 and the warning device 150. The controller 140 analyzes the posture of the human body according to the magnitude and the range of the pressure sensed by the pressure sensor 120 when the temperature sensor 130 determines that the pressure is derived from the human body. It is understood that the posture of the human body can be reflected by the size and shape of the contact surface between the human body and the pad 110, and the size and shape of the contact surface can be known by the pressure size and the pressure range sensed by the pressure sensor 120.
Further, the controller 140 also performs continuous timing during the time when the human posture is not changed, and restarts the timing when the human posture is changed. A maximum time value is preset for the controller 140, and when the controller 140 analyzes that the continuous timing when the posture of the human body is not changed reaches the preset maximum time value, the warning device 150 is started to send a warning.
In this embodiment, the warning device 150 may be a buzzer capable of emitting sound warning information, a vibrator capable of emitting vibration warning information, or both a buzzer and a vibrator.
The reset unit 160 is connected to the controller 140, and the reset unit 160 can restart the timing of the controller 140 and control the warning device 150 to stop issuing the warning. In practical use, the reset unit 160 can be in the form of a button, and the button is pressed to perform a reset operation, so that the warning function of the pressure sensing mat 100 is more humanized, and the warning device 150 is prevented from giving a warning for a long time due to a failure of the timing function of the controller 140.
In this embodiment, the pad 110 is a mattress, and is suitable for long-term bedridden people such as paralysis and disability, because the human body can press the human tissue of the contact part with the bed during the bedridden period, the blood circulation is not smooth due to the same posture being kept for a long time, and adverse symptoms such as bedsore can be generated after a long time.
In this embodiment, the controller 140 divides the lying posture of the person lying in bed into a left lying posture, a right lying posture and a lying posture, continuously counts the time while the person lying in bed keeps the same lying posture, and starts the warning device 150 to issue a warning when the continuous timing for keeping the same lying posture reaches a preset maximum time value. The nursing staff can regularly adjust the lying posture of the bedridden staff according to the received warning information.
Further, the wireless communication unit 170 is connected to the controller 140, and can transmit information of the posture of the human body, the duration of holding the same posture, or the duration of issuing a warning to an external display terminal. Specifically, the display terminal may be an intelligent terminal with a display function, such as a mobile phone and a tablet computer. The holder of the display terminal, such as the relatives of the bedridden people, can conveniently check the state of the bedridden people.
Referring to fig. 2, a first embodiment of the present invention further provides a method for prompting a pressure sensing pad, including the following steps:
s101: activating the temperature sensor 130 to analyze whether the pressure on the mat 110 is from the human body when the pressure sensor 120 senses that the mat 110 is under pressure;
s102: when the temperature sensor 130 determines that the pressure of the pad 110 is from the human body, the start controller 140 analyzes the posture of the human body according to the pressure magnitude and the pressure range sensed by the pressure sensor 120, and continuously counts the time when the posture of the human body is not changed; and
s103: when the controller 140 continuously counts time and reaches a preset maximum time value, the controller controls the warning device 150 to issue a warning.
Specifically, in step S102, the controller 140 restarts the timing when it determines that the human body posture is changed. In addition, when the temperature sensor 130 determines that the pressure on the pad 110 is not from the human body, the controller 140 is not activated, and the temperature sensor 130 is activated at all times or intermittently during the time when the pressure sensor 120 senses that the pad 110 is under pressure.
Referring to fig. 3, a pressure sensing mat 200 with a prompting function is also provided in a second embodiment of the present invention, the pressure sensing mat 200 provided in this embodiment is substantially the same as the pressure sensing mat 100 provided in the first embodiment, and also includes a pad 210, a pressure sensor 220, a temperature sensor 230, a controller 240, an alarm device 250, a reset unit 260 and a wireless communication unit 270.
The pressure sensing mat 200 provided in the present embodiment is different from the pressure sensing mat 100 provided in the first embodiment in that: the pad 210 is a seat cushion, and is suitable for drivers of mobile devices such as automobiles, and because the drivers may sleep due to fatigue driving during driving, traffic accidents are easily caused, and thus, the drivers need to be prompted when the drivers may be in a sleep state to improve driving safety.
In this embodiment, the pressure sensing pad 200 further includes an acceleration sensor 281 and a steering sensor 282. The acceleration sensor 281 can sense the acceleration of the vehicle, for example, the acceleration is generated when the vehicle brakes or accelerates, it can be understood that the acceleration is generated along with the operation of the driver on the brake or the accelerator when the vehicle runs on a smooth road, and the driver can be considered not to be in an unconscious sleeping state when the driver operates the brake or the accelerator. The steering sensor 282 is capable of sensing a directional deflection of the vehicle, and it is understood that the directional deflection is accompanied by a steering operation of the driver when the vehicle travels on a smooth road, and the driver may be considered not to be in an unintended sleep state when the driver operates the steering.
The acceleration sensor 281 and the steering sensor 282 are respectively connected to the controller 240, and the controller 240 analyzes the posture of the human body based on the pressure magnitude and the pressure range sensed by the pressure sensor 220, the acceleration sensed by the acceleration sensor 281, and the directional deflection sensed by the steering sensor 282. Since the posture of the driver is changed to a small extent when the vehicle travels on a smooth road, the magnitude of the pressure sensed by the pressure sensor 220 and the magnitude of the pressure range change may not be sufficient for the controller 240 to determine the change in the posture of the driver. The addition of the acceleration sensor 281 and the steering sensor 282 is advantageous to improve the accuracy of the controller 240 in analyzing whether the human posture is changed.
In actual use, when a driver sits on the pad 210, the pressure sensor 220 senses that the pad 210 is pressed, and at this time, the temperature sensor 130 is started and can determine that the pressure of the pad 210 is from a human body. Then, the controller 240 analyzes the posture of the human body according to the magnitude and range of the pressure sensed by the pressure sensor 220, the acceleration sensed by the acceleration sensor 281, and the direction deflection sensed by the steering sensor 282, and continuously counts the time before the posture of the human body is changed. The controller 240 controls the warning device 250 to issue a warning when the continuous timing reaches a preset maximum time value. Note that, the controller 240 determines that the human posture is changed when the acceleration sensor 281 senses acceleration or the steering sensor 282 senses directional deflection, and restarts the timing.
It can be understood that in the pressure sensing mat 100 provided in the first embodiment, the warning sent by the warning device 150 is mainly used for reminding the nursing person of the bedridden person, because the bedridden person cannot turn over actively, and therefore, the warning device 150 is disposed in the work area of the nursing person or the equipment carried by the nursing person. In the pressure sensing mat 200 according to the second embodiment, the warning device 250 is mainly used for reminding a driver, and therefore, the buzzer included in the warning device 250 is disposed in the vehicle, and the vibrator is directly accommodated in the gasket 210. Further, the vibrator may be set such that the intensity of the vibration generated each time is gradually increased from weak to weak, improving the effect of prompting the driver.
Similarly, the wireless communication unit 270 sends the information of the sitting posture of the driver, the holding time length in the same sitting posture or the warning sending time length to the external display terminal, so that the driver can conveniently check the driving state of the driver by the holder of the display terminal, such as the relative of the driver or the rental car company to which the driver belongs.
Referring to fig. 4, a second embodiment of the present invention further provides a method for prompting a pressure sensing pad, including the following steps:
s201: when the pressure sensor 220 senses that the pad 210 is under pressure, the temperature sensor 230 is activated to analyze whether the pressure on the pad 210 is from a human body;
s202: when the temperature sensor 230 determines that the pressure of the pad 210 is from the human body, the controller 240 is started to analyze the posture of the human body according to the pressure magnitude and the pressure range sensed by the pressure sensor 220, and continuously time when the posture of the human body is not changed;
s203: when the controller 240 continuously counts time and reaches a preset maximum time value, the warning device 250 is controlled to send out a warning.
Specifically, in step S202, the controller 240 restarts the timing when determining that the human body posture is changed. In addition, when the temperature sensor 230 determines that the pressure on the pad 210 is not from the human body, the controller 240 is not activated, and the temperature sensor 230 is activated at all times or intermittently during the time when the pressure sensor 220 senses that the pad 210 is under pressure.
Further, in step S202, the controller 240 further analyzes whether the human body posture is changed according to the acceleration sensed by the acceleration sensor 281 and the direction deflection sensed by the steering sensor 282, and directly determines that the human body posture is changed when the acceleration sensor 281 senses the acceleration or the steering sensor 282 senses the direction deflection.
In addition, other modifications within the spirit of the invention may occur to those skilled in the art, and such modifications are, of course, included within the scope of the invention as claimed.
