Embodiment Construction

[0025] To realize the algorithm of fall detection, it is first necessary to establish the communication between the three-axis acceleration sensor ADXL345 and the single-chip microcomputer STC89C52. use I 2 The C communication protocol transfers data from the ADXL345 to the bus. It is related to the collection and transmission of data. 1. Data transmission between ADXL345 and STC89c52

[0026] In our invention we have only one master STC89C52 and one slave ADXL345. Start signal (S): When SCL is high level, SDA jumps from high level to low level, indicating that data transmission will start; end signal (P): when SCL is high level, SDA changes from low level to low level A high level transition indicates the end of data transmission;

[0027] Response signal (ACK): After receiving 8-bit data, the slave machine pulls down the SDA level in the 9th cycle, indicating that the data has been received. This ACK signal is called an acknowledgment signal.

[0028] The host STC89C52...

Abstract

The invention relates to research and design of a portable GSM&GPS fall detector. According to the invention, modules such as an ADXL345 three-axis acceleration sensor, a single-chip microcomputer and a GPS&GSM are combined together to realize detection of accidental fall and transmission of position information after the fall; and a complete fall detection algorithm is designed. The algorithm is executed according to four states in a fall accident, namely, a weightless state, collision with the ground, comparison of the state of the body of a user after collision with the state of the body before collision, and a motionless state.

Description

technical field [0001] The invention combines ADXL345, single-chip microcomputer and GPS&GSM module to realize the detection of accidental fall and the sending of position information after the fall. The present invention has two main functions: GSM (Global System for Mobile Communications) and GPS (Global Positioning System). The invention belongs to the field of detection control and communication, and has the characteristics of low cost, low power consumption and portability. It can be applied to the fields of electronic engineering and surveying and mapping. Background technique [0002] Nowadays, the life span of human beings is becoming longer and longer. With the improvement and development of living standards, the problem of aging is becoming more and more obvious. For older people, due to the degeneration of body functions, many accidents are difficult to avoid, such as accidental falls. Many elderly people lose consciousness after falls and delay the timing of f...
