Device of tracking alarm for realizing low power consumption and falling detection and mutual switching method of low power consumption and falling detection

Abstract

The present invention relates to a device of tracking alarm for realizing low power consumption and falling detection and a mutual switching method of low power consumption and falling-down detection, and relates to a detection device and a mutual switching method of low power consumption and falling detection. The device comprises an MCU, a mobile phone GSM module, a mobile phone GPS module, a power supply module, an accelerometer and a display module; an interruption INT1 is taken as a motion switch detection interruption under the low power consumption, and an interruption INT2 is taken as a falling detection interruption; if falling happens, it is determined whether the falling occurs or not according to the whole falling detection algorithm through comparison of the triaxial accelerations of the weightlessness, the knocking and the quiescence of the falling and after falling with the original state prior to the falling; when an anti-falling instrument is turned on for 30s and does not have any operation, the anti-falling instrument will enter a standby state; and an accelerometer is configured to be a wake-up mode prior to the MCU entering the low power consumption, and the determination of falling detection is performed. In the condition of ensuring the detection reliability, the device of tracking alarm for realizing low power consumption and falling detection and the mutual switching method of low power consumption and falling detection reduce the complexity of a circuit, decrease the volume of itself power consumption of a circuit board and reduce the cost.

Description

Technical field [0001] The invention relates to a detection device and a mutual switching method thereof, in particular to a detection device and a mutual switching method thereof for simultaneously realizing low power consumption and falling. Background technique [0002] The elderly are prone to accidental falls due to the decline in their self-protection ability. Therefore, it is necessary to reliably detect falling products to ensure timely rescue after such accidents. Products that detect the fall of the elderly often require long-term wear by the elderly, and therefore have more stringent requirements in terms of weight, size, and low power consumption. [0003] At present, there are a large number of fall detection products on the market based on the accidental fall of the elderly. The detection components of this type of product mainly consist of MCU, three-axis accelerometer, vibration switch and corresponding circuit. Rely on the three-axis accelerometer to detect the ...
