Detailed Implementation Methods

[0051] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0052] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0053] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0054] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0055] One embodiment of the present invention provides a stable detection device. Figure 1 This is a schematic diagram of the appearance of a stability testing device according to an embodiment of the present invention, as shown below. Figure 1 As shown, the stability testing device includes a probe 11 and a slide 12. The width of the slide 12 gradually narrows. The subject holds the probe 11 and touches the bottom of the slide 12, sliding it from the wide end to the narrow end. The stability testing device can detect whether the subject touches the side wall of the slide 12 while holding the probe 11 and sliding it, thereby reflecting whether the subject's arm is stable.

[0056] In one implementation of this invention, a subject can use a stability testing device to test whether their arm is stable. The subject can be a pilot, driver, elderly person, patient, etc. Figure 2A This is a top view schematic diagram of the handwriting of a probe in a stable detection device according to an embodiment of the present invention, as shown below. Figure 2A As shown, the subject holds the probe 11 and touches the bottom of the slide 12, sliding it from the wide end to the narrow end of the slide 12. The trajectory of the probe 11 at the bottom of the slide 12 is a straight line and does not touch the side wall of the slide 12. The probe trajectory diagram can be used to characterize the movement trajectory of the probe in the slide. At this time, the probe trajectory diagram is a straight line, indicating that the subject's arm stability is very good.

[0057] Figure 2B This is a top view schematic diagram of the handwriting of the probe pen in another stable detection device provided in an embodiment of the present invention, as shown below. Figure 2B As shown, the subject held the probe 11 and touched the bottom of the slide 12, sliding it from the wide end to the narrow end of the slide 12. The trajectory of the probe 11 at the bottom of the slide 12 was a curve, and the probe left the bottom of the slide 12 when it touched the side wall of the slide 12. At this time, the probe trajectory diagram was a curve, and the curve broke when the probe left the bottom of the slide 12, indicating that the subject's arm stability was good.

[0058] Figure 2C This is a top view schematic diagram of the handwriting of the probe pen in another stable detection device provided in an embodiment of the present invention, as shown below. Figure 2CAs shown, the subject held the probe 11 and touched the bottom of the slide 12, sliding it from the wide end to the narrow end. The trajectory of the probe 11 at the bottom of the slide 12 consisted of multiple line segments, repeatedly touching the side wall of the slide 12 and leaving the bottom of the slide 12 multiple times. At this time, the probe trajectory diagram consisted of multiple line segments, and the line segments broke when the probe left the bottom of the slide 12 multiple times, indicating that the subject's arm stability was poor.

[0059] Figure 3 An equivalent circuit diagram of the bottom of a groove provided in an embodiment of the present invention is shown below. Figure 3 As shown, if the resistance at the bottom of the chute is uniformly distributed, the position of the probe can be calculated. From Figure 3 From the equivalent circuit diagram, the voltage across the probe changes as it slides along the bottom of the slot, and current flows through it. The position of the probe on the bottom of the slot is calculated as follows:

[0060] (V1-Vx) / (R3 / / Rx4)=(Vx-V2) / (R2 / / Rx5), where Rx4+Rx5 is the total resistance of the bottom of the chute, Vx is the voltage (second detection value) collected in real time by the probe, V1 is the voltage at one end of the bottom of the chute, V2 is the voltage at the other end of the bottom of the chute, and R3 and R2 are the voltage divider resistors when the probe collects the voltage in real time. In one embodiment of the present invention, since the total resistance of the bottom of the chute (Rx4+Rx5) is a known parameter, and Vx is the voltage (second detection value) collected in real time by the probe is also a known parameter, the resistance values ​​of Rx4 and Rx5 can be calculated according to the above formula, and the location of the probe can be determined according to the resistance value distribution of Rx4 and Rx5.

[0061] Figure 4 This is a schematic diagram of the structure of a stability detection device provided in an embodiment of the present invention, as shown below. Figure 4 As shown, if the slide 12 of the stability testing device is a resistor with uniform impedance, meaning the resistance at the bottom of the slide is evenly distributed, and the two ends of the slide 12 are connected to the power supply and ground respectively, when the subject slides the probe 11, the stability testing device will determine the position of the probe 11 based on the real-time voltage value collected from the slide. However, after repeated use, the bottom of the slide 12 will wear down, and the resistance of the slide 12 will decrease with the increase of sliding times. This causes the resistance at the bottom of the slide to no longer be evenly distributed, and the actual position of the probe 11 will differ from the position corresponding to the voltage value. Consequently, the actual position of the probe 11 displayed on the screen will be inaccurate, affecting the reliability of the stability testing device. The change in resistance at the bottom of the slide of the stability testing device due to wear and other reasons prevents accurate positioning of the probe. Therefore, the probe cannot accurately draw its movement trajectory in the slide, resulting in an inaccurate movement trajectory that cannot characterize the subject's arm stability.

[0062] In one embodiment of the present invention, the chute is divided into several segments for voltage detection. The position of the probe is determined based on the analog-to-digital converter (ADC) value corresponding to the voltage value of each segment and the ADC value measured in real time at the current position of the probe. This ensures that the probe can be located even if the bottom of the chute is worn, thus preventing the inability to obtain the probe's movement trajectory in stability measurement. This embodiment of the present invention provides a stability detection device and a stability detection calibration method. Figure 5 This is a schematic diagram of the structure of a stability testing device according to an embodiment of the present invention. Figure 6 A flowchart of a stability detection and calibration method provided in an embodiment of the present invention is shown below. Figure 5 or Figure 6 As shown, the method includes:

[0063] Step 102: Obtain the first detection value of each of the multiple reference positions of the bottom of the chute, wherein the multiple reference positions of the bottom of the chute correspond to the end point of each of the multiple segments divided along the length direction of the bottom of the chute.

[0064] In one embodiment of the present invention, each step is executed by a processor in the stability detection device. For example, the processor is a microcontroller. The stability detection device can be an arm horizontal stability detection device. The stability detection device may include a processor, a chute, a probe, an ADC, and a multiplexer (MUX).

[0065] Specifically, the first detection values ​​of multiple reference positions at the bottom of the chute are obtained through MUX.

[0066] In one embodiment of the present invention, the first voltage value obtained by directly measuring the voltage at the bottom of the tank is called the first detection value of the reference position of the bottom of the tank. The first detection value may also include the first ADC value generated based on the first voltage value.

[0067] In one embodiment of the present invention, the end point of each segment obtained by the bottom of the trench, whether by physical division or algorithmic division, is called the reference position.

[0068] In one implementation of this invention, the bottom of the chute can be a continuous whole without physical distinction. Instead, several equally divided points are selected sequentially along the length of the chute, and these equally divided points are used as the end points of each segment.

[0069] In another implementation of the present invention, the bottom of the chute can also be a discontinuous whole, for example, divided into nine equal segments, which can be physically separated from each other.

[0070] Step 104: In response to the first operation input by the user, obtain the second detection values ​​when the probe touches different positions on the bottom of the tank. The first operation includes the user holding the probe and controlling the probe to slide along the bottom of the tank.

[0071] Specifically, the user holds a probe and slides it at different positions on the bottom of the slide to obtain a second detection value of the slide by sliding the probe.

[0072] In one embodiment of the present invention, during the stability test conducted by the user, the second voltage value detected on the probe when the probe touches the bottom of the tank is called the second detection value of the probe. The second detection value may also include a second ADC value generated based on the second voltage value.

[0073] Step 106: Based on the first detection values ​​at the bottom of the tank and the second detection values ​​at the probe, determine the positions of the probe at the bottom of the tank during the response process of the first operation.

[0074] In the technical solution provided by this invention, the method is applied to a stability testing device, which includes a probe and a chute. The method includes: acquiring first detection values ​​at multiple reference positions on the bottom of the chute, wherein the multiple reference positions on the bottom of the chute correspond to the end point of each of multiple segments divided along the length direction of the bottom of the chute; in response to a first operation input by a user, acquiring second detection values ​​when the probe contacts different positions on the bottom of the chute, the first operation including the user holding the probe and controlling the probe to slide along the bottom of the chute; and determining the positions of the probe on the bottom of the chute during the response of the first operation based on the first detection values ​​on the bottom of the chute and the second detection values ​​of the probe. In the technical solution provided by this invention, regardless of how the resistance value of the chute changes, the position of the probe can be determined based on the first detection values ​​on the bottom of the chute and the second detection values ​​of the probe. Changes in the resistance value of the chute will not affect the determined position of the probe, thus improving the reliability of the stability testing device.

[0075] One embodiment of the present invention provides another stable detection and calibration method. Figure 7 A flowchart of another stability detection and calibration method provided in an embodiment of the present invention is shown below. Figure 7 As shown, the method includes:

[0076] Step 202: Obtain the first detection value of each of the multiple reference positions of the bottom of the chute through a multiplexer, wherein the multiple reference positions of the bottom of the chute correspond to the end point of each of the multiple segments divided along the length direction of the bottom of the chute.

[0077] In one embodiment of the present invention, each step is performed by a stability detection device, which can be an arm horizontal stability detection device. The stability detection device includes a processor, a slide, a probe, an ADC, and a MUX.

[0078] In one embodiment of the present invention, the bottom of the chute of the stability testing device can be divided into multiple segments along its length, with the end point of each segment corresponding to a reference position of the chute, and each segment of the chute bottom connected to the MUX. For example... Figure 5 As shown, the chute of the stability testing device can be considered as a resistor with uniform impedance, with the power supply and ground connected to its two ends respectively. The chute of the stability testing device can be divided into 9 segments, with the end point of each segment corresponding to a reference position of the chute.

[0079] In one embodiment of the present invention, the first detection values ​​of 8 reference positions in 9 segments at the bottom of the chute of the stable detection device can be directly acquired via a MUX. The first detection values ​​include the first voltage value of the chute or the first ADC value generated based on the first voltage value.

[0080] In one embodiment of the present invention, the first ADC value at each position can be used to represent the first voltage value corresponding to each of the 8 reference positions in the 9 segments of the chute. For example, if the power supply voltage of the stability detection device is 3.3V, and the first voltage value corresponding to one of the positions is 3.3V, then the first ADC value corresponding to the first voltage value of 3.3V is 2. 14 .

[0081] In one embodiment of the present invention, before step 102, the method may further include: determining the theoretical values ​​of each reference position on the bottom of the tank based on the total number of segments divided at the bottom and the fixed parameters of the circuit used to obtain the detection values. Specifically, this is achieved using the formula ADC(x) = (x*2) / ( ... n ) / X sum The theoretical values ​​for each reference position on the bottom of the tank are generated by calculating the total number of segments and the fixed parameters of the circuit used to acquire the detection values. Here, ADC(x) is the theoretical value for the Xth segment (each reference position), n is the fixed parameter of the circuit used to acquire the detection values ​​(which can be a fixed parameter of the processor (such as a microcontroller), and x can represent the number of bits of the theoretical value for each reference position; n can be 14, X... sum X represents the total number of segments divided into at the bottom of the trench. sum It can be 9.

[0082] Step 204: Compare the first detection value of the reference position with the theoretical value of the reference position, and determine whether the difference between the first detection value of the reference position and the theoretical value of the reference position obtained in advance exceeds the set allowable range. If yes, proceed to step 206; if no, proceed to step 208.

[0083] In one embodiment of the present invention, if it is determined that the difference between the first detected value of the reference position and the theoretical value of the reference position obtained in advance does not exceed the set allowable range, it indicates that the resistance value of the slide of the stable detection device has not changed significantly and no calibration is required, and step 208 is executed; if it is determined that the difference between the first detected value of the reference position and the theoretical value of the reference position obtained in advance exceeds the set allowable range, it indicates that the resistance value of the slide of the stable detection device has changed significantly and calibration is required, and step 206 is executed.

[0084] In one embodiment of the present invention, the allowable range can be set according to the actual situation. For example, the allowable range can be 2% or more.

[0085] Step 206: In response to the first detection value of the reference position and the theoretical value of the reference position obtained in advance exceeding the set allowable range, determine the positions of the probe at the bottom of the tank during the response process of the first operation based on the first detection values ​​at the bottom of the tank and the second detection values ​​of the probe.

[0086] In step 206, the error of the theoretical value of the reference position is relatively large compared with the first detection value of the reference position. The position of the probe cannot be deduced from the theoretical value. Therefore, the real-time measured value (first detection value) of each reference position at the bottom of the tank is used as a threshold to compare with each second detection value of the probe to determine the position of the probe at the bottom of the tank.

[0087] In one embodiment of the present invention, the subject holds a probe and controls it to slide along the bottom of a groove. The probe can be used to obtain second detection values ​​at different positions where it contacts the bottom of the groove. The second detection values ​​include a second voltage value at which the probe contacts the bottom of the groove or a second ADC value generated based on the second voltage value.

[0088] Specifically, step 206 includes: comparing the second detection value of the probe with the first detection value of each reference position to determine the closest reference position or the position with equal voltage. The closest reference position or the position with equal voltage value is the position of the probe at the bottom of the tank during the response of the first operation.

[0089] In one embodiment of the present invention, the resistance value of the slide of the stable detection device has changed significantly, and the error between the second detection value of the probe and the first detection value of each reference position is small. At this time, the cause of the error is generally the unstable power supply voltage or the error generated when the probe collects the second detection value. Since the above error is small, it can be processed by the filtering algorithm.

[0090] In one embodiment of the present invention, the stability detection device can generate the trajectory of each probe on the bottom of the groove according to the position of each probe, and determine the motion stability detection and / or analysis results based on the trajectory.

[0091] In one embodiment of the present invention, the stability detection device can be communicatively connected to the display screen. The stability detection device sends the aforementioned trajectory to the display screen, which can display the trajectory to represent the movement trajectory of the probe at the bottom of the groove.

[0092] Step 208: In response to the difference between the first detection value of the reference position and the theoretical value of the reference position being within the set allowable range, determine the positions of the probe at the bottom of the tank during the response process of the first operation based on the second detection values ​​of the probe.

[0093] In step 208, the error of the theoretical value at the reference position is smaller than the first detected value at the reference position. The position of the probe can be deduced from the theoretical value. When the resistance at the bottom of the chute is evenly distributed, this method can be used to deduce the position of the probe. For example, if the resistance distribution at the bottom of the chute is good, this method in step 208 can be set as the preferred method to reduce the amount of calculation.

[0094] In one embodiment of the present invention, if the difference between the first detected value at the reference position and the theoretical value at the reference position is within a set allowable range, then it can be determined according to the following... Figure 3 The equivalent circuit diagram of the bottom of the chute shown is used to calculate the position of the probe, which will not be elaborated here.

[0095] In one embodiment of the present invention, the stability detection device can generate the trajectory of each probe on the bottom of the groove according to the position of each probe, and determine the motion stability detection and / or analysis results based on the trajectory.

[0096] In the technical solution provided by this invention, the method is applied to a stability testing device, which includes a probe and a chute. The method includes: acquiring first detection values ​​at multiple reference positions on the bottom of the chute, wherein the multiple reference positions on the bottom of the chute correspond to the end point of each of multiple segments divided along the length direction of the bottom of the chute; in response to a first operation input by a user, acquiring second detection values ​​when the probe contacts different positions on the bottom of the chute, the first operation including the user holding the probe and controlling the probe to slide along the bottom of the chute; and determining the positions of the probe on the bottom of the chute during the response of the first operation based on the first detection values ​​on the bottom of the chute and the second detection values ​​of the probe. In the technical solution provided by this invention, regardless of how the resistance value of the chute changes, the position of the probe can be determined based on the first detection values ​​on the bottom of the chute and the second detection values ​​of the probe. Changes in the resistance value of the chute will not affect the determined position of the probe, thus improving the reliability of the stability testing device.

[0097] The technical solution provided in this embodiment of the invention eliminates the need for frequent replacement of the slide of the stable detection equipment, thus reducing maintenance costs.

[0098] One embodiment of the present invention provides another stable detection and calibration method. Figure 8A flowchart of another stability detection and calibration method provided in an embodiment of the present invention is shown below. Figure 8 As shown, the method includes:

[0099] Step 302: Obtain the first detection value of each of the multiple reference positions of the bottom of the chute through a multiplexer, wherein the multiple reference positions of the bottom of the chute correspond to the end point of each of the multiple segments divided along the length direction of the bottom of the chute.

[0100] In one embodiment of the present invention, each step is performed by a stability detection device, which can be an arm horizontal stability detection device. The stability detection device includes a processor, a slide, a probe, an ADC, and a MUX.

[0101] In one embodiment of the present invention, the bottom of the chute of the stability testing device can be divided into multiple segments along its length, with the end point of each segment corresponding to a reference position of the chute, and each segment of the chute bottom connected to the MUX. For example... Figure 5 As shown, the chute of the stability testing device can be considered as a resistor with uniform impedance, with the power supply and ground connected to its two ends respectively. The chute of the stability testing device can be divided into 9 segments, with the end point of each segment corresponding to a reference position of the chute.

[0102] In one embodiment of the present invention, the first detection values ​​of 8 reference positions in 9 segments at the bottom of the chute of the stable detection device can be directly acquired via a MUX. The first detection values ​​include the first voltage value of the chute or the first ADC value generated based on the first voltage value.

[0103] In one embodiment of the present invention, the first ADC value at each position can be used to represent the first voltage value corresponding to each of the 8 reference positions in the 9 segments of the chute. For example, if the power supply voltage of the stability detection device is 3.3V, and the first voltage value corresponding to one of the positions is 3.3V, then the first ADC value corresponding to the first voltage value of 3.3V is 2. 14 .

[0104] In one embodiment of the present invention, before step 202, the method may further include: determining the theoretical values ​​of each reference position on the bottom of the tank based on the total number of segments divided at the bottom and the fixed parameters of the circuit used to acquire the detection values. Specifically, this is achieved using the formula ADC(x)=(x*2 n ) / X sum The theoretical values ​​for each reference position on the bottom of the tank are generated by calculating the total number of segments and the fixed parameters of the circuit used to acquire the detection values. Here, ADC(x) is the theoretical value for the Xth segment (each reference position), n is the fixed parameter of the circuit used to acquire the detection values ​​(which can be a fixed parameter of the processor (such as a microcontroller), and x can represent the number of bits of the theoretical value for each reference position; n can be 14, X... sum X represents the total number of segments divided into at the bottom of the trench. sumIt can be 9.

[0105] Step 304: Compare the first detection value of the current reference position with the theoretical value of the reference position, and determine whether the difference between the first detection value of the reference position and the theoretical value of the reference position obtained in advance exceeds the set allowable range. If yes, proceed to step 306; if no, proceed to step 310.

[0106] In one embodiment of the present invention, if it is determined that the difference between the first detected value of the reference position and the theoretical value of the reference position obtained in advance does not exceed the set allowable range, it indicates that the resistance value of the slide of the stable detection device has not changed significantly and no calibration is required, and step 310 is executed; if it is determined that the difference between the first detected value of the reference position and the theoretical value of the reference position obtained in advance exceeds the set allowable range, it indicates that the resistance value of the slide of the stable detection device has changed significantly and calibration is required, and step 306 is executed.

[0107] In one embodiment of the present invention, the allowable range can be set according to the actual situation. For example, the allowable range can be 2% or more.

[0108] Step 306: In response to the first detection value of the current reference position and the theoretical value of the reference position obtained in advance exceeding the set allowable range, determine the positions of the probe at the bottom of the tank during the response process of the first operation based on the current first detection value at the bottom of the tank and the current second detection value of the probe.

[0109] In step 306, the error of the theoretical value of the reference position is relatively large compared with the first detection value of the reference position. The position of the probe cannot be deduced from the theoretical value. Therefore, the real-time measured value (first detection value) of each reference position at the bottom of the tank is used as a threshold to compare with each second detection value of the probe to determine the position of the probe at the bottom of the tank.

[0110] In one embodiment of the present invention, the subject holds a probe and controls it to slide along the bottom of a groove. The probe can be used to obtain second detection values ​​at different positions where it contacts the bottom of the groove. The second detection values ​​include a second voltage value at which the probe contacts the bottom of the groove or a second ADC value generated based on the second voltage value.

[0111] Specifically, step 306 includes: comparing the second detection value of the probe at a reference position with the first detection value at the reference position to determine the closest reference position or the position with equal voltage. The closest reference position or the position with equal voltage is the position of the probe at the bottom of the tank during the response of the first operation.

[0112] In one embodiment of the present invention, the resistance value of the slide of the stable detection device has changed significantly. The error between the second detection value of the probe at a reference position and the first detection value at the reference position is small. At this time, the cause of the error is generally the unstable power supply voltage or the error generated when the probe collects the second detection value. Since the error is small, it can be processed by a filtering algorithm.

[0113] In one embodiment of the present invention, the stability detection device can generate the trajectory of each probe on the bottom of the groove according to the position of each probe, and determine the motion stability detection and / or analysis results based on the trajectory.

[0114] In one embodiment of the present invention, the stability detection device can be communicatively connected to the display screen. The stability detection device sends the aforementioned trajectory to the display screen, which can display the trajectory to represent the movement trajectory of the probe at the bottom of the groove.

[0115] Step 308: Move the probe to the next reference position of the slide, and use the next reference position as the current reference position and continue to step 304.

[0116] In one embodiment of the present invention, the subject holds a probe and controls the probe to slide on the bottom of the groove, moving the probe from the current position of the groove to the next position of the groove.

[0117] As an alternative, if the subject leaves the bottom of the trough with the probe in hand, the stable detection device will not be able to obtain the second detection value, and the process will end.

[0118] As an alternative, if the subject slides the probe along the bottom of the trough for a time exceeding a set time threshold, the stable detection device will no longer acquire a second detection value, and the process will end. In one embodiment of the present invention, a set time threshold can be set according to actual conditions. For example, the set time threshold is 1 minute.

[0119] Step 310: In response to the difference between the first detection value of the current reference position and the theoretical value of the reference position being within the set allowable range, determine the positions of the probe at the bottom of the tank during the response process of the first operation based on the current second detection value of the probe, and continue to execute step 308.

[0120] In step 310, the error of the theoretical value at the reference position is smaller than the first detected value at the reference position. The position of the probe can be deduced from the theoretical value. When the resistance at the bottom of the chute is evenly distributed, this method can be used to deduce the position of the probe. For example, if the resistance distribution at the bottom of the chute is good, this method in step 310 can be set as the preferred method to reduce the amount of calculation.

[0121] In one embodiment of the present invention, if the difference between the first detected value at the reference position and the theoretical value at the reference position is within a set allowable range, then it can be determined according to the following... Figure 3 The equivalent circuit diagram of the bottom of the chute shown is used to calculate the position of the probe, which will not be elaborated here.

[0122] In one embodiment of the present invention, the stability detection device can generate the trajectory of each probe on the bottom of the groove according to the position of each probe, and determine the motion stability detection and / or analysis results based on the trajectory.

[0123] In the technical solution provided by this invention, the method is applied to a stability testing device, which includes a probe and a chute. The method includes: acquiring first detection values ​​at multiple reference positions on the bottom of the chute, wherein the multiple reference positions on the bottom of the chute correspond to the end point of each of multiple segments divided along the length direction of the bottom of the chute; in response to a first operation input by a user, acquiring second detection values ​​when the probe contacts different positions on the bottom of the chute, the first operation including the user holding the probe and controlling the probe to slide along the bottom of the chute; and determining the positions of the probe on the bottom of the chute during the response of the first operation based on the first detection values ​​on the bottom of the chute and the second detection values ​​of the probe.
