[0039] Embodiment 1

[0040] Figure 1The flowchart of a body movement state monitoring method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of detecting the body movement state of a monitoring object during sleep. This method can be executed by a monitoring device, which includes: a chip, an upper electrode plate, an elastic interlayer, and a lower electrode plate. The monitoring device can be configured in articles convenient for human use, such as a mattress. As Figure 1 shown, the method includes:

[0041] S110. When the monitoring object exerts pressure on the monitoring device, detect the pressure according to the corresponding deformation generated by the elastic interlayer and the distance between the upper electrode plate and the lower electrode plate.

[0042] Among them, the elastic interlayer of the monitoring device can use elastic materials, such as sponge, etc. The upper electrode plate and the lower electrode plate of the monitoring device can adopt flexible conductive materials. Flexible conductive materials generally consist of a flexible substrate that is inexpensive, easy to obtain, and can be used for a long time, and a conductive layer with good conductivity. The commonly used flexible substrate is polydimethylsiloxane, and the conductive materials usually include metal materials, inorganic nano-conductive materials, etc. The flexible conductive material made by combining the two has low cost, is thin and light, and can also conveniently place this monitoring device in articles convenient for human use, such as a mattress, so as to monitor the body movement state of a human during daily life or sleep.

[0043] Preferably, the flexible conductive material can adopt existing conductive cloth. The conductive cloth uses a fiber cloth (generally polyester fiber cloth is commonly used) as the base material, and after pre-treatment, an electroplated metal coating is applied to make it have metal characteristics and become a conductive fiber cloth. The conductive cloth is widely used in the production of work clothes for workers engaged in electronics, electromagnetic and other high-radiation work. In the embodiment of the present invention, the conductive cloth is creatively used as the flexible conductive material of the pad, which can be folded and washed, and has a low cost.

[0044] It should be noted that the upper electrode plate and the lower electrode plate are arranged oppositely. At least one of the upper electrode plate and the lower electrode plate is composed of multiple pieces of conductive materials for collecting multiple channels of signals to realize the monitoring of the body movement state of the monitoring object. Specifically, the optimal solution is that both the upper and lower electrode plates can collect multiple channels of signals. The second-best solution is that the upper electrode plate can collect multiple channels of signals and the lower electrode plate can collect one channel of signal. The third-best solution is that the upper electrode plate can collect one channel of signal and the lower electrode plate can collect multiple channels of signals. Among them, the electrode plate that can collect multiple channels of signals uses multiple strip-shaped conductive cloths (the strip-shaped conductive cloths can be cut from a whole piece of conductive cloth), and the electrode plate that can collect one channel of signal uses a whole piece of conductive cloth.

[0045] Specifically, when the monitoring object presses on the item with the built-in monitoring device, the elastic interlayer in the monitoring device will deform, and the distance between the upper electrode plate and the lower electrode plate will also change. The chip in the monitoring device can detect the pressure received by the monitoring device according to the deformation of the elastic interlayer and the distance between the upper electrode plate and the lower electrode plate, and then determine the body movement state of the monitoring object based on the pressure.

[0046] S120. Record the pressure area and pressure position of the pressure within the set time period.

[0047] Among them, the set time period can be considered as a pre-set period of time, such as from 23:00:00 to 23:15:00. The chip in the monitoring device can obtain and record the pressure area and pressure position where the monitoring device is subjected to pressure through the method of arrayed multi-channel signals.

[0048] S130. Determine the body movement state of the monitoring object according to the pressure area and pressure position of the pressure within the set time period.

[0049] Among them, the body movement state of a human body is usually turning left, turning right, lying flat, foot movement, hand movement, etc. In this embodiment, the monitoring device can be built into the mattress corresponding to the human leg position. Therefore, the body movement state of the monitoring object can be normal leg movement, frequent leg movement, etc.

[0050] Specifically, it is possible to determine whether the monitoring object is lying on the mattress with the built-in monitoring device and the pressure is on the legs according to the change amount of the pressure value, the pressure area and the pressure position, and then record the change frequency and amplitude of the pressure value, the change frequency and amplitude of the pressure area, and the change frequency and position of the pressure position within the set time period, and determine whether the monitoring object has a behavior of getting out of bed, that is, the behavior of the monitoring object detaching from the monitoring device.

[0051] It should be noted that the purpose of monitoring body movement through the monitoring device in this embodiment is to monitor the body movement state of the monitoring object without affecting the sleep of the monitoring object. For example, some people may have involuntary limb movements during sleep, showing periodic repetitive stereotyped movements. If the monitoring device detects involuntary periodic limb movements of the lower limbs of the monitoring object, it can be considered that there are abnormal body movements (such as restless legs) and other phenomena, which is convenient for further observation and correction of the body movement of the monitor.

[0052] Optionally, determining the body movement state of the monitoring object according to the pressure area and pressure position of the pressure within the set time period includes:

[0053] Determine the pressure disappearance time within the set time period;

[0054] If, within a set time period, during the time period before the pressure disappearance time, the change frequency and change amplitude of the pressure area and pressure position show an increasing trend, and during the time period after the pressure disappearance time, the change frequency and change amplitude of the pressure area and pressure position also show an increasing trend, then it is determined that the body movement state of the monitored object is abnormal body movement.

[0055] Specifically, if the change frequency and change amplitude of the pressure area show an increasing trend and are accompanied by small-range and high-frequency changes in the pressure position, it can be determined that the monitored object has an act of detaching from the monitoring device. At this time, the pressure disappearance time within the set time period can be determined. After the monitored object returns to the monitoring device again, the change frequency and change amplitude of the pressure area and pressure position are reduced compared to the values before leaving the monitoring device, but the overall trend afterwards shows an increasing trend. Then it is determined that the body movement state of the monitored object is abnormal body movement.

[0056] Optionally, the change frequency and change amplitude of the pressure area and pressure position during the time period after the pressure disappearance time are respectively smaller than the change frequency and change amplitude before the pressure disappearance time.

[0057] Specifically, the change frequency and change amplitude of the pressure area and pressure position during the time period after the pressure disappearance time are respectively smaller than the change frequency and change amplitude before the pressure disappearance time. That is, after the monitored object returns to the monitoring device again, the change frequency and amplitude of the pressure area and pressure position of the pressure are decreased compared to before detaching from the monitoring device. That is, before the monitored object gets out of bed, the change of the pressure area and pressure position shows an increasing trend. After getting out of bed, when the monitored object returns to bed again, the change of the pressure area and pressure position also shows an increasing trend, but the overall change trend after getting out of bed is smaller than that before getting out of bed. In this case, even if the monitored object detaches from the monitoring device within the set time period, it will be recorded, so that the entire body movement state of the monitored object within the set time period can be monitored more accurately and comprehensively.

[0058] An embodiment of the present invention provides a method for monitoring body movement state, which is applied to a chip of a monitoring device. The monitoring device further includes an upper electrode plate, an elastic interlayer, and a lower electrode plate. The method includes: when the monitored object generates pressure on the monitoring device, detecting the pressure according to the corresponding deformation generated by the elastic interlayer and the distance between the upper electrode plate and the lower electrode plate; recording the pressure area and pressure position of the pressure within the set time period; and determining the body movement state of the monitored object according to the pressure area and pressure position of the pressure within the set time period. By using the above method, the body movement state of the monitored object is determined by detecting the pressure area and pressure position of the pressure on the leg of the monitored object within the set time period. There is no need to use electronic components such as wearable sensors, the cost is low, and it does not affect the normal activities of the monitor.

[0059] Embodiment Two

[0060] Figure 2Schematic flowchart of a body movement state monitoring method provided in the second embodiment of the present invention. The second embodiment is refined based on the above embodiments. In this embodiment, the process of determining the body movement state of the monitoring object according to the pressure area and pressure position within a set time period is specifically described. It should be noted that the technical details not described in detail in this embodiment can be referred to any of the above embodiments.

[0061] As Figure 2 shown, the method includes:

[0062] S210. Determine the capacitance change amount according to the effective area of the deformation generated by the elastic interlayer and the change amount of the distance between the upper electrode plate and the lower electrode plate.

[0063] Among them, when the monitoring object lies on the bed with the built-in monitoring device, the elastic interlayer will generate deformation, and the distance between the upper electrode plate and the lower electrode plate will also change. It can be considered that the area of the pressure part where the monitoring object contacts and overlaps with a single electrode plate is the effective area of the deformation of the elastic interlayer. The effective area of the deformation of the elastic interlayer and the change of the distance between the upper and lower electrode plates will cause a change in the capacitance of the electrode plates.

[0064] Specifically, the chip in the monitoring device can use the following formula to calculate the capacitance change amount:

[0065] C = (ε0 × ε × S) / D

[0066] Where ε0 is the vacuum permittivity, ε is the relative permittivity of the medium between the electrode plates, S is the effective area of the deformation of the elastic interlayer, and D is the change amount of the distance between the upper and lower electrode plates.

[0067] S220. Determine the pressure according to the capacitance change amount.

[0068] Specifically, the capacitance change amount is positively correlated with the pressure value. Considering the chip cost, the capacitance change amount can also be directly used to determine the pressure value, that is, the pressure value can be determined according to the change amount of the capacitance after the monitoring object presses on the monitoring device. In addition, the capacitance change amount can also be converted into a voltage value, and the voltage value is used to represent the pressure.

[0069] S230. Record the pressure area and pressure position of the pressure within a set time period.

[0070] S240. Determine the body movement state of the monitoring object according to the change frequency and change amplitude of the pressure area and pressure position of the pressure within a set time period.

[0071] Optionally, if within the set time period, both the change frequency and change amplitude of the pressure area and pressure position show an increasing trend, then determine the body movement state of the monitoring object according to the first threshold.

[0072] Among them, the first threshold can be a threshold greater than the leg movement frequency and amplitude in the normal human activity state. If, within the set time period, both the change frequency and change amplitude of the pressure area and pressure position show an increasing trend, there is no behavior of detaching from the monitoring device, and the increasing trend is greater than the first threshold, then it can be determined that the body movement state of the monitoring object is abnormal body movement. Among them, the normal activity state can refer to the sleep state, so as to monitor the body movement during sleep.

[0073] Optionally, if, within the set time period, both the change frequency and change amplitude of the pressure area and pressure position remain within the specified range, then determine the body movement state of the monitoring object according to the second threshold.

[0074] Among them, the second threshold can be a range threshold of the leg movement frequency and amplitude that conforms to the normal human sleep state. If, within the set time period, both the change frequency and change amplitude of the pressure area and pressure position remain within the specified range, it means that the body movement of the monitoring object remains in a state without major changes. On this basis, if both the change frequency and change amplitude of the pressure area and pressure position belong to the second threshold range, then it can be determined that the body movement state of the monitoring object is normal body movement.

[0075] In addition, if, within the set time period, both the change frequency and change amplitude of the pressure area and pressure position are greater than the second threshold and less than the first threshold, then it can be determined that the body movement state of the monitoring object is normal body movement without entering the sleep state.

[0076] Optionally, if, within the first time period of the set time period, both the change frequency and change amplitude of the pressure area and pressure position show a decreasing trend, and within the second time period of the set time period, both the change frequency and change amplitude of the pressure area and pressure position remain unchanged, then determine that the body movement state of the monitoring object is normal body movement.

[0077] Among them, if the set time period is from 22:30:00 to 23:00:00, then the first time period of the set time period can be from 22:30:00 to 22:45:00, and the second time period can be from 22:45:00 to 23:00:00. Within the first time period, both the change frequency and change amplitude of the pressure area and pressure position show a decreasing trend, and within the second time period of the set time period, both the change frequency and change amplitude of the pressure area and pressure position remain unchanged, that is, it can be considered that the monitoring object is in a normal activity state without entering sleep within the first time period, and is in a static state after normal activity or enters the sleep state within the second time period, that is, it can be determined that the body movement state of the monitoring object is normal body movement.

[0078] Optionally, generate corresponding prompt information according to the body movement state of the monitoring object, and push the prompt information to the terminal connected to the monitoring device.

[0079] Specifically, the chip of the monitoring device can be connected to the terminal in a wired or wireless manner, and then can generate corresponding prompt information according to the body movement state of the monitoring object, and push the prompt information to the terminal connected to the monitoring device. For example, if the body movement state of the monitoring object is abnormal, a risk warning information for abnormal body movement can be generated and pushed to the terminal so that the monitoring object can understand his / her physical condition.

[0080] Figure 3 FIG. is a schematic flowchart of a process for judging the body movement state of a ward object provided by an embodiment of the present invention. As Figure 3 shown, the specific steps include:

[0081] S30. The monitoring device collects the pressure signal of the monitoring object.

[0084] S33. Judge whether the pressure value, pressure area and pressure position of the pressure conform to the leg characteristics of the monitoring object according to the algorithm. If so, execute S34; if not, execute 39.

[0085] S34. Determine the body movement state of the monitoring object according to the change frequency and change amplitude of the pressure area and pressure position of the pressure within a set period.

[0086] S35. Judge whether the body movement state of the monitoring object is abnormal. If so, execute S36; if not, execute 38.

[0087] S36. Generate a risk prompt information for the monitoring object with abnormal body movement, and push the prompt information to the terminal connected to the monitoring device.

[0088] S37. Generate a prompt information indicating that the monitoring object is not on the bed, and push the prompt information to the terminal connected to the monitoring device.

[0089] S38. Generate a prompt information for the normal body movement of the monitoring object, and push the prompt information to the terminal connected to the monitoring device.

[0090] S39. Generate a prompt information indicating that the monitoring object is on the bed, and push the prompt information to the terminal connected to the monitoring device.

[0091] An embodiment of the present invention provides a body movement state monitoring method, which is applied to a chip of a monitoring device. The capacitance change amount is calculated according to the effective area of the deformation of the elastic interlayer and the change amount of the distance between the upper and lower electrode plates, so as to quantify the pressure, providing an accurate basis for the monitoring device to judge the body movement state of the monitoring object; by determining the body movement state of the monitoring object according to the change frequency and change amplitude of the pressure area and pressure position of the pressure within a set time period, and generating corresponding prompt information according to the body movement state of the monitoring object, and pushing the prompt information to a terminal connected to the monitoring device, it is possible to accurately judge the body movement state of the monitoring object without affecting the sleep and psychology of the monitoring object, and timely push a risk warning prompt to users with abnormal body movements (such as restless legs).
