In one embodiment, the acceleration acquisition unit 22 is an ADXL345 acceleration sensor. The process of human falling is accompanied by imbalance of the body. Due to the acceleration of gravity, the human body falls to the ground, and this process is generally irreversible. This process generally occurs in 1-3 seconds, a very short period of time. The ADXL345 accelerometer can measure static gravitational acceleration in tilt detection applications, as well as dynamic acceleration due to motion or shock. Its high resolution (3.9mg/LSB) enables the measurement of tilt angle changes of less than 1.0°. The inclination angle refers to the bending angle of the body trunk, including the left and right inclination and the front and rear inclination of the torso. According to the size of the inclination angle, the direction of the fall of the human body can also be judged. Studies have shown that when the human body is standing, the angle between the body and the vertical direction generally does not exceed 60 degrees. But it is difficult to classify body poses completely and correctly based on lean angle alone. Therefore, the inclination angle is often used as an auxiliary index for posture classification to further judge the possible fall events. The vertical velocity is similar to the acceleration value, and the vertical velocity curve can also represent the kinematic characteristics of the different stages of the falling process. All fallers experience a stage in the downward vertical velocity curve. These data collected by ADXL345 module can be used as effective parameters for fall prediction.

SVM表示人体合加速度的幅值，其数值的大小反应人体运动加速度的大小。该特征值的优点在于将空间三维加速度合成一个矢量，在阈值判断时可以忽略该矢量的空间方向，只判读是否超过某一阈值。The acceleration of the human body during the movement of the earth can be decomposed into components in three directions. The acceleration in the x-axis direction is a _x , the acceleration in the y-axis direction is a _y , and the acceleration in the z-axis direction is a _z . Then the acceleration vector of human motion is

SVM represents the magnitude of the resultant acceleration of the human body, and the magnitude of its value reflects the magnitude of the acceleration of human motion. The advantage of this eigenvalue is that the spatial three-dimensional acceleration is synthesized into a vector, and the spatial direction of the vector can be ignored when judging the threshold, and only whether it exceeds a certain threshold is judged.

The process of fall detection is shown in Figure 3. First, the acceleration sensor ADXL345 takes the acceleration of three axes, and then compares the acquired acceleration with the threshold value, and then judges whether the threshold value of at least one axis exceeds the threshold value. If it does not exceed, continue to collect the acceleration of the three axes; if it exceeds, for example, delay 15s. During the delay process, if it is a false fall, the acceleration of the three axes will continue to be collected. If it is not a false fall, the monitoring crutches will send an alarm to the monitoring service terminal and forward it to the guardian, and receive this dangerous message to notify the guardian in time. , for assistance as soon as possible.

The purpose of the smart walking monitoring crutch of the utility model is to obtain the necessary rescue, which involves the problem of data transmission of the alarm information. First of all, the rescue must know the location of the injured person. The SIM900A module is selected, and the SIM card and GPS positioning unit are used to realize the transmission of the alarm and the positioning information. . When a fall accident is detected, it will be uploaded to the monitoring service terminal through an AT command data (data composition: device ID + status < status of the elderly, whether to locate GPS> + latitude and longitude + terminator), as shown in Figure 4, A forwarding process is performed through the server, and the mobile terminal is requesting a data from the server to realize the forwarding of the data, so as to notify the guardian in time and carry out rescue processing as soon as possible.
