Problems solved by technology

[0005] The inventors have found that the above-mentioned motion detection device has the following problems: structurally speaking, this motion detection device divided into two parts has a relatively large volume, and the two parts need to be installed on the same horizontal line so that the transmitting part and the receiving part Alignment; Functionally, it can only detect two states of on and off. The detectable scene and detectable state are single, and it cannot detect other complex motion states, such as detecting whether valuables are moved, whether the notebook is opened, etc.

Abstract

The present invention provides a motion state detection device, a motion state detection method and a motion state detection system. The device includes a gravity sensor for sensing acceleration and outputting the X-axis component, Y-axis component and Z-axis component of the acceleration, a magnetometer for sensing magnetic field intensity and outputting the X-axis component, Y-axis component and Z-axis component of the magnetic field intensity, a processor used for acquiring the three-axis components of the gravity sensor and the three-axis components of the magnetometer and processing the three-axis components of the gravity sensor and the three-axis components of the magnetometer so as to identify a motion state, and a wireless module used for transmitting identified motion state information. According to the motion state detection device, the motion state detection method and the motion state detection system of the invention, data outputted by the gravity sensor and the magnetometer are processed so as to fit the characteristic value of a motion model, and therefore, the motion state of a measured object can be judged, and accurate identification of the motion state of the measured object can be realized.

Description

technical field [0001] The present invention relates to the field of program control, and more specifically, to a motion state detection device, method and system. Background technique [0002] At present, the motion detection devices used for home door and window security on the market are mainly door magnets, and its components are mainly fixed magnets, reed switches and transmitters. The working principle of this kind of door magnetism is to install the fixed magnet on the door, and install the reed switch and transmitter on the door frame. When the door is opened and closed, the fixed magnet opens the reed switch or closes the reed switch to realize the door switch action detection. , to further realize alarm and other functions. [0003] Another common motion detection device currently on the market is mainly composed of an infrared receiver, a transmitter and an alarm signal transmitter. Its working principle is that the transmitter end emits infrared signals, and th...
