Description

Human body falling monitoring device

Technical Field

The utility model relates to a human gesture monitoring technology field, in particular to human low limbs gesture monitoring technology, concretely relates to human monitoring device that tumbles.

Background

The posture recognition of the lower limbs of the human body has important significance for monitoring the old, in particular for monitoring and rescuing the falling of the old living alone. The human lower limbs are relatively complex organs in the whole human body structure, and the human lower limb behaviors and postures can be divided into two types according to the moving state of the foot body: one is the lower extremity behavioral attitude with the foot body remaining stationary, such as standing, sitting and squatting; the other is the lower limb behavior posture of the foot body keeping the motion state, such as walking, running, jumping, kicking, pedaling and the like. At present, a technology for recognizing the posture of the lower limbs of the human body based on the plantar pressure distribution information has been proposed. The technologies utilize the pressure difference of the walking posture of the human body at different parts of the foot bottom, so that not only the gait of the human body can be identified through the distribution information of the foot bottom pressure, but also the static lower limb behavior posture of the foot body can be identified through the information of the foot bottom pressure.

Chinese patent publication No. CN203059714U discloses a plantar pressure distribution measuring system, which can determine the posture of the foot body by detecting data with pressure sensors arranged on the soles.

However, due to the lack of information on the moving direction and moving speed of the foot body, it cannot be used for recognition of the behavior posture of the lower limbs such as running, jumping, kicking, and the like in the movement of the foot body based on the sole pressure distribution information. For example, in the application of intelligent recognition of human body falling, for the behavior posture of a person sitting on a chair to lift both legs, since the sole pressure is zero, the misjudgment of human body falling may be generated only by the sole pressure information.

The utility model discloses a human monitoring device that tumbles adopts pressure sensor monitoring plantar pressure to distribute, and gyroscope sensor monitoring foot body moving direction, accelerometer monitoring foot body moving speed. The lower limb behavior posture in the static state of the foot body can be identified by the sole pressure distribution data continuously collected by the device, and the lower limb behavior posture in the moving state of the foot body can be identified by the data of the moving direction and the moving speed of the foot body continuously collected by the device.

The utility model discloses a human monitoring device that tumbles structure is shown in fig. 1, data collection station, power and data processing module, transmission module and backstage equipment including pressure sensor 10, acceleration sensor 11 and gyroscope sensor 12 constitution.

The pressure sensor 10, the acceleration sensor 11 and the gyroscope sensor 12 transmit the acquired data to the power supply and data processing module 13, the power supply and data processing module 13 processes the data, and the processing result is transmitted to the background equipment through the transmission module 14.

In the data acquisition device, a pressure sensor 10 is used for acquiring the pressure of the sole of a human body, an acceleration sensor 11 is used for acquiring the movement speed of the human body, and a gyroscope sensor 12 is used for acquiring the movement direction of the human body. The data can be processed to make accurate judgment on the human body posture.

Examples

For convenience of description, according to the characteristics of the walking state of the human body, the stressed part of the foot body can be generally divided into four parts, such as a heel 101, an outer side 102 of the arch, the arch 103 and a forefoot 104 as shown in fig. 2 as an example. The left sole is symmetrical to the right sole.

Under the walking state of the human body, the stress states of the heel 101, the outer side 102 of the arch, the arch 103 and the half sole 104 are different, and particularly, the stress parts of the foot body are different in time sequence in the walking process. And the stress time sequence is usually easier to detect than the stress magnitude, stress direction and the like.

Based on this, the present invention respectively sets the pressure sensor 10 in three areas, namely, the heel 101, the outer side of the arch 102 and the forefoot 104, and respectively collects the pressure data of 3 collection points. In fig. 2, the heel 101 has 2 pressure sensors 10 arranged laterally; the arch outer side 102 has 2 pressure sensors 10 arranged longitudinally; the area of the forefoot 104 is larger, 3 pressure sensors 10 are arranged, and the 3 pressure sensors 10 are arranged basically in parallel and slightly have a slight radian, so that the stress characteristics of the forefoot are better met.

In the normal walking state of the human body, the stress time sequence of the foot body is that the pressure sensor arranged on the heel 101 firstly acquires data, then the pressure sensor arranged on the outer side 102 of the arch of foot acquires data, and finally the pressure sensor arranged on the forefoot 104 acquires data. The above-mentioned stress process occurs alternately for the left and right feet.

The power supply and data processing module 13 can accurately judge the walking posture by the time sequence relation of data collected by the pressure sensors 10 in the heel 101, the outer side 102 of the arch and the half sole 104 and by combining the human body movement speed data collected by the acceleration sensor 11 and the movement direction data collected by the gyroscope sensor 12.

The power and data processing module 13 transmits the determination result to the mobile phone of the user through the transmission module 14 in a Bluetooth (Bluetooth) communication manner.

The acceleration sensor 11 and the gyro sensor 12 of the present embodiment are formed by MEMS (Micro-Electro-Mechanical-Systems) devices, and have the characteristics of small volume, low cost and mature technology.

The pressure sensor 10 adopts a flexible pressure sensor, can be arranged on a shoe pad, and is convenient for integrating a human body falling monitoring device with background equipment into a wearable device arranged in the shoe.

In the wearable device of the present example, the flexible pressure sensor is placed on the insole, and the acceleration sensor 11, the gyroscope sensor 12, the power and data processing module 13, and the transmission module 14 are all placed in the sole of the shoe at the arch of the foot under the insole, as shown in fig. 2.

The power supply and data processing module 13 of this embodiment is composed of a lithium battery, a charging and discharging circuit, and a DSP (digital signal processor) or MCU (microprocessor) for supplying electric power to the entire apparatus and performing data processing.

Example 2

The basic structure of the human body falling monitoring device is the same as that of the embodiment 1, and the main difference is that the power supply and data processing module 13 only performs the preprocessing of data, including the shaping of the acquired signals and the encoding of the data, except for supplying power.

This may further simplify the structure of the wearable device and may allow for more complex, powerful and intelligent data processing systems.

The data of the embodiment is transmitted to the background equipment and then judged and further processed, the background equipment such as a mobile phone and the like can have stronger processing capacity and artificial intelligence and learning capacity, and whether the human body falls down or not is accurately detected by learning the data characteristics of the user in normal standing and walking states such as stress time sequence, duration, speed change rule, stability of motion direction and the like of the left and right foot pressure sensors, even the early warning signal about falling down can be sent through artificial intelligence learning, and the function and the application range of the human body falling monitoring device are further expanded.
