Detailed Description
Example 1
As shown in fig. 1 and fig. 2, an intelligent falling detection pad comprises a plurality of detection unit pads capable of being spliced and a communication host, wherein each detection unit pad comprises a pad body, a detection circuit board and a PET ink sensor are arranged in the pad body, the PET ink sensor is connected with the detection circuit board, and the detection circuit board is connected with a server through a communication module of the communication host.
Each detection unit pad is communicated with a communication host in a Bluetooth broadcasting or mesh networking mode. The communication host wirelessly receives information of the detected body in each detection unit pad, processes the detection result of the detection unit pad, and if the detection result is judged to fall, the host sends alarm information to the platform through WIFI, NB-IOT and the like.
In this embodiment, the size of the detection unit pad is 30×30cm, the PET ink sensors are designed in a dot matrix layout, and the PET ink sensor at each dot position can sense pressure and trigger. For example, an inductive lattice in a rectangular array, as shown in figure one.
For example: according to bathroom shower areas with different sizes, a plurality of detection unit pads can be assembled in a combined mode, and the communication host is installed on a wall. When the old people stand on the detection unit pad, the stepped detection unit pad is woken up to work, and the detection unit pad which is not stepped on continues to sleep, so that the standby time of the detection unit pad is prolonged. The circuit corresponding to the stepped detection unit pad detects the signal of the triggered PET ink sensor at the same time, and then the signal is transmitted to the communication host in a Bluetooth wireless broadcasting mode, and the communication host receives the signal and is connected with the server through the communication module, and the server stores and comprehensively analyzes the signal.
The posture of the old on the cushion mainly comprises standing, sitting and sliding. And the triggered points and the triggered intervals are combined with the time, so that the posture of the old is judged and the alarm is given.
The gesture recognition method comprises the following steps: when the detection unit pads are spliced and laid, each detection unit pad can form a unique equipment ID through Bluetooth MAC, and a two-dimensional code is formed on the detection unit pad. When laying, the mobile phone APP scans the two-dimensional code of the detection unit pad, and corresponding detection unit pads are sequentially laid according to the indication of the APP, each detection unit pad is put, the APP sends the ID and the position coordinates of the detection unit pad to the server, and the server records corresponding information. This completes the coordinate assignment of the sensing units of all the sensing unit pads.
In the standing state, two force point groups are formed due to standing of the feet. For example, an adult may trigger a number of points ranging from about 14 to 18 points, with a spacing of 30 to 60cm between the two points of force.
In sitting state, the buttocks and lower limbs form three force point groups, the number of points triggered by the buttocks of an adult is 10-15 points, the number of points triggered by the feet is about 10-14 points,
in the lying state, four or more force point groups are formed, namely, the head, the shoulder, the back, the buttocks and the heel, and the total point number triggered by one adult is about 13-20 points.
The judging gesture can be based on the number Ngro of the force point groups, the distance between two points with the largest distance in the point groups is Dmax, and the total trigger point number is Ntri. And judging that the number of the adjacent points of the full communication is greater than or equal to 1 as a group of the acting points.
And Ngro >2 and Dmax >60, judging falling (both sitting and lying are judged to fall), and immediately sending a falling alarm signal if the falling is not returned to a standing state within 10 seconds (Ngro is less than or equal to 2 and Dmax < 60).
The detection unit pad adopts a Bluetooth/zigbee wireless transmission and button battery power supply mode, so that a communication host and the detection unit pad are not connected by wires, and the movement of the old is more convenient. The detection pad is formed by splicing standard detection unit pads, the stepped detection unit pads trigger to work, so that the working time of the detection unit pads is prolonged, and the frequent replacement of batteries by old people is reduced.
Through the combination mode that the unit can splice, can adapt to the bathroom of different areas.
The PET ink sensor is adopted for dot matrix design, so that the cost is greatly reduced. By identifying the number and distribution of the sensing points and combining the time, the falling is judged, and the falling identification accuracy can be extremely high. The communication host can also integrate infrared and microwave detection functions, so that human and non-human targets can be effectively detected, and false alarm is reduced.
