In a preferred embodiment, when a user uses the mattress testing apparatus 100 to perform a hardness test of a mattress, the user needs to keep the apparatus balanced, that is, the lower surface of the housing 110 is in a horizontal balanced state, while holding the apparatus 100 in order to obtain an accurate measurement result. For this purpose, the indicator light 130 may be four RGB indicator lights 131 and 134 for representing four directions of the device 100. The acceleration sensor detects balance data of the mattress detection apparatus 100, transmits the balance data to the control part, and the control part determines balance state information of the apparatus according to the balance data and controls the indicator lamp 130. Preferably, the balance data is an angular difference between the device 100 detected by the acceleration sensor and the corresponding dimensional axis in the horizontal balance state, and the control unit determines the balance state information of the device 100 according to the angular difference data of each dimensional axis.

If the device 100 has a plurality of positions in unbalance, the control part controls the RGB indicating lamps corresponding to the plurality of positions to display the first color to prompt the user.
When the mattress sensing apparatus 100 is in a balanced state, i.e., the lower surface of the housing 110 is in a horizontal balanced state, and the RGB indicator 130 displays the second color or does not display the second color, the user may release the apparatus 100 at a certain height from the mattress, so that the user can freely fall onto the mattress.

Specifically, when the device 100 is in a falling process, the acceleration sensor always detects falling acceleration data of the device 100, the control unit calculates a current falling stroke according to the falling acceleration data at different times, and after the device 100 is stopped, that is, when the falling acceleration of the device is zero, the maximum falling stroke is selected from the calculated falling stroke data and is used as the falling stroke measured at this time to be compared with standard sample data, so as to generate mattress hardness information.
In a preferred embodiment, the mattress softness or hardness information is appropriate, softer, harder, or fails to detect; if the hardness information of the mattress is proper, the control component controls the indicator lamp 130 to display according to the first color matching information; if the hardness information of the mattress is soft, the control component controls the indicator lamp 130 to display according to second color matching information; if the hardness information of the mattress is hard, the control component controls the indicator lamp 130 to display according to third color matching information; if the hardness information of the mattress is detection failure, the control component controls the indicator lamp 130 to display according to the fourth color matching information. Preferably, the first color matching information is that the four RGB indicating lamps are green; the second color matching information is that the three RGB indicating lamps are green, and one RGB indicating lamp is red; the third color matching information is that three RGB indicating lamps are all red, and one RGB indicating lamp is green; and the fourth color matching information is that the four RGB indicating lamps are all red. Of course, which specific RGB indicator lamps display a color in a group can be flexibly set as required. If the three RGB indicator lamps 131 and 133 in the second color matching information are all green, one RGB indicator lamp 134 is red; the third color matching information is that the three RGB indicator lamps 131 and 133 are all red, and one RGB indicator lamp 134 is green. Optionally, the control component is connected with the terminal through a bluetooth communication module, and outputs the hardness and softness information of the mattress to the terminal.

As shown in fig. 2, it is a schematic diagram of the circuit connection of the embodiment of the mattress detection device of the present invention. The control unit 210 may optionally use a central processor or a micro-control unit, such as an Apollo3 chip, to provide control and data transfer. The acceleration sensor 220 can be an ultra-low power consumption 3-axis acceleration sensor, such as LIS331DLH, to detect balance data and falling acceleration data of the mattress detection device. The indicator light 130, which may be a three-color RGB indicator light, indicates various states of the device operation. The bluetooth communication module 230 is disposed on the circuit board 120, electrically connected to the control unit 210, or a low power consumption bluetooth communication module built in the control unit 210, for performing bluetooth communication with an external device. The tact switch 150 can be pressed for a long time or a short time to realize the functions of the mattress detection device 100 such as power on/off, detection mode on, and the like. Further, the mattress detection device 100 may include a battery 170 to supply power to the device, and the battery 170 may be a conventional coin cell CR2032 to provide DC 3V. The battery 170 may be disposed outside the circuit board 120 or directly disposed on the circuit board 120.
As shown in fig. 3, it is a schematic view of the detection process of the embodiment of the mattress detection device of the present invention. Specifically, when the mattress detection equipment provided by the embodiment is used for detecting the hardness of the mattress, the operation can be carried out according to the detection flow.
Step 310: the user presses the tact switch 150 for a long time (preferably, the pressing time is3 seconds or more) to turn on the mattress inspection device 100. Alternatively, in the case where the device includes a bluetooth communication module, the device enters a bluetooth connection state, one indicator light 130 may appear as a blue flash (e.g., 0.5 seconds/time), and the other indicator lights 130 do not appear. The user opens the terminal, finishes bluetooth binding, and after the bluetooth connection succeeds, one indicator light 130 can appear blue and be always on for 5 seconds. Preferably, if the user does not perform bluetooth binding within 1 minute, the bluetooth connection state is exited. After the first bluetooth binding, the next boot device 100 may not enter the bluetooth connection state any more, but directly enter the power-on state. In the device on state, the user may press the tact switch 150 for a long time (preferably, the pressing time is greater than or equal to 5 seconds), so that the device enters the bluetooth connection state, and the bluetooth binding between the terminal and the mattress detection device 100 is performed again.
Step 320: the user briefly presses the tact switch 150 (preferably, the pressing time is less than or equal to 2 seconds) to turn on the detection mode, so that the apparatus 100 enters the test state (i.e., enters the mattress detection process). The user uses the handheld device 100 to hang on the mattress to be tested, and keeps a certain distance with the bed surface, and the recommended value is less than or equal to 5 mm. For testing the accuracy of the results, it is preferred that the device 100 is spaced from the mattress by a distance of ≦ 2 mm. Preferably, after a short press of the tact switch 150, all the indicator lights 130 appear to blink green and slow (e.g., 1 second/time) to give the user a prompt. Alternatively, if the user does not perform other operations after a short press of the tact switch 150, such as 1.5 minutes, the device 100 exits the test state and shuts down.
Step 330: the user slowly adjusts the device 100 to perform a balance calibration to maintain the device 100 in a horizontally balanced state. At this time, the apparatus 100 is in a test standby state, the acceleration sensor continuously detects the balance data of the apparatus 100 and transmits the balance data to the control part, and the control part determines the balance state information of the apparatus according to the balance data. As mentioned above, during the adjustment process of the user, the corresponding indicator light 130 on the lower side of the device may display a red fast flash (e.g. 0.25 sec/time) under the control of the control unit to give the user a prompt, specifically:
if the left side of the device 100 is down, the left indicator light 132 will display a red fast flash, and the other indicator lights may be green slow flash (e.g., 1 second/time) or not display;
if the right side of the device 100 is down, the right indicator light 133 will flash red faster, while the other indicator lights will flash green slower or not;
if the front of the device 100 is down, the front indicator 134 will flash red faster, while the other indicators may flash green slower or not;
if the device 100 is tilted down, the rear indicator 131 will flash red faster, and the other indicators may flash green slower or not.
The user adjusts the balance status of the device 100 according to the indication of the indicator lights 130 until all the indicator lights 130 are flashed green or not displayed.
Step 340: when the equipment 100 is in a balanced state and reaches the test standard, that is, all the indicator lights 130 are green and slowly flashed or do not display, the user loosens the equipment 100, so that the equipment freely falls onto the mattress to be tested, and the hardness of the mattress is detected.
Step 350: when the device 100 is stopped, the control unit calculates the falling stroke of the device according to the falling acceleration data detected by the acceleration sensor, determines whether the detection is successful, generates a mattress hardness and softness detection result (i.e., mattress hardness and softness information), and displays the detection result through the indicator lamp 130.
Specifically, the acceleration sensor detects the falling acceleration data of the mattress detection device 100, and sends the falling acceleration a of the device 100 to the control unit, and the control unit uses the acceleration displacement formula
The sag displacement x of the device 100 on the mattress is calculated. Since the device 100 is closer (less than or equal to 5mm) to the mattress at the start of the test, the initial velocity v of the device 100 can be defaulted0Is equal to 0, so
The falling time t can be obtained by a clock test built in the control unit. As previously mentioned, the acceleration sensor always detects the fall acceleration data of the apparatus 100 while the apparatus 100 is falling, and the control unit calculates the current fall stroke, e.g., at t, from the fall acceleration data at different times1The falling acceleration of the time of day apparatus 100 is a1The control unit calculates t1The falling stroke, i.e. the sinking displacement, of the time device 100 is x1(ii) a At t2The falling acceleration of the time of day apparatus 100 is a2The sag displacement is x2(ii) a At t3The falling acceleration of the time of day apparatus 100 is a3The sag displacement is x3. When the apparatus 100 is stationary, i.e., when the falling acceleration is zero, the maximum falling stroke, e.g., x, is selected from the plurality of calculated falling stroke data3As the falling stroke of the measurement, the control component can generate the hardness detection result of the mattress by comparing with the standard sample data, and the detection result is indicated by the indicator lamp 130. It should be noted that the time interval for the control unit to calculate the fall stroke is small enough to make the measured maximum fall stroke as accurate as possible and reduce the measurement error.
As mentioned above, preferably, if the hardness of the mattress is detected to be appropriate, the control unit controls the four indicator lights 130 to be normally on in green; if the hardness detection result of the mattress is soft, the three indicator lights 130 are all green and normally on, and one indicator light 130 is red and normally on; if the hardness detection result of the mattress is hard, the three indicator lights 130 are all red and normally on, and one indicator light 130 is green and normally on; if the hardness detection result of the mattress is detection failure, if the device 100 is unbalanced in the falling process, the four indicator lights 130 are all red and normally on. Optionally, if the device 100 is connected to the terminal via bluetooth, the control unit may send the hardness and softness detection result of the mattress to the terminal, and display the specific degree of deviation between the mattress to be detected and the standard value via application software. The terminal can upload the detection result to the cloud platform for storage, so that the user can use the detection result in a follow-up query mode.
The standard sample data can be measured by experiment. For example, a standard sample scene is a wooden bed plus a cotton pad with a thickness of 5cm, and the height of the equipment from the cotton pad in each detection process is consistent through the detection process. The falling acceleration value of the apparatus 100 is recorded, and the maximum falling displacement value is calculated. The test and the recording are repeated, and the number of the data samples is preferably equal to or larger than 100. And then, performing data fitting on at least 100 data samples to obtain standard sample data and an allowable error range. Finally, the standard sample and the allowable error range data are written in the control unit. Thus, when the equipment 100 works normally, the control part compares the equipment falling displacement stroke value detected each time with the written standard sample data, and checks whether the error range is exceeded, and finally gives the mattress hardness detection result. For example, if the detected falling stroke value of the equipment is standard sample data or within an allowable error range, the detection result of the hardness of the mattress is appropriate; if the detected falling stroke value of the equipment is larger than the standard sample data and the allowable error range, the detection result of the hardness of the mattress is soft; and if the detected falling stroke value of the equipment is smaller than the standard sample data and the allowable error range, the hardness and softness detection result of the mattress is hard. In the above example, the cotton pad with the thickness of about 5cm paved on the wood board bed is used as a standard sample scene because the mattress has moderate hardness, can meet the needs of body curves of most people, keeps the straight and normal physiological radian of the spine, and has great benefits for sleeping and health.
It will be appreciated that in the actual mattress testing process, the height of the device from the mattress is made to coincide with the height used in the process of determining the standard sample, so as to ensure the accuracy of the test.
