Above-mentioned a kind of intelligent anti-theft alarm device that can identify angle, it is characterized in that: the input end of described single-chip microcomputer is connected with three axis accelerometer, three-axis gyroscope, three axle magnetometers respectively, single-chip microcomputer adopts IIC communication modes to carry out communication with three sensors respectively.When power switch closes, whole system is in power-up state, the now acceleration information of three axis accelerometer Real-time Collection door, the angular velocity data of three-axis gyroscope Real-time Collection door, magnetic field strength date under environment residing for three axle magnetometer Real-time Collection doors, and the data collected are sent in single-chip microcomputer, single-chip microcomputer uses Kalman filtering algorithm to carry out filtering and noise reduction to the acceleration and angular velocity data that collect door, the magnetic field strength date simultaneously collected three axle magnetometers uses ellipse fitting algorithm to correct, nine number of axle certificates after process merge by final single-chip microcomputer, be converted into Eulerian angle accurately to export.

Above-mentioned a kind of intelligent anti-theft alarm device that can identify angle, is characterized in that: the output terminal of described single-chip microcomputer is connected to dual-colored LED lamp, hummer and GPRS module.When swarming into without personnel, door is in the state of closing, and within the Eulerian angle that now single-chip microcomputer exports are stabilized in the threshold range of single-chip microcomputer inner setting, dual-colored LED lamp presents green, and hummer does not make a sound, and whole system is in low power consumpting state.When there being personnel to swarm into, door is opened into certain angle, single-chip microcomputer triggered interrupts, wake up from low power consumpting state, the door data that now three axis accelerometer, three-axis gyroscope, three axle magnetometers collect change a lot, single-chip microcomputer is by merging nine number of axle certificates after process, generation Big Euler angle exports, when the Eulerian angle exported are greater than the Eulerian angle threshold value of single-chip microcomputer inner setting, the personnel that truly have proved swarm into, now the connected hummer of Micro Controller Unit (MCU) driving makes a sound, and dual-colored LED lamp is rendered as redness; Meanwhile, the connected GPRS module of Micro Controller Unit (MCU) driving sends note to user, and timely reminding user house is stolen.

Above-mentioned a kind of intelligent anti-theft alarm device that can identify angle, is characterized in that: the output terminal of described single-chip microcomputer is connected to bluetooth module.When user opens door, only need carry out communication with the bluetooth module in mobile phone and intelligent apparatus, if the password of user mobile phone input is consistent with Bluetooth pairing password, each pin of Micro Controller Unit (MCU) driving is low level, and device quits work.If user wants to restart this device, only the reset key be connected with single-chip microcomputer input end need be pressed.

Above-mentioned a kind of intelligent anti-theft alarm device that can identify angle, is characterized in that: the input end of described single-chip microcomputer is connected to supply module, and this module adopts dry cell power supply, is conveniently easy to get.

The utility model compared with prior art has the following advantages:

1, structure simple, with low cost, easily operate.

2, adopt the sensor of high precision, high integration as data collector, single-chip microcomputer inside embedded in the data anastomosing algorithm of pin-point accuracy simultaneously, substantially increases the accuracy rate of burglar alarm.

Hereafter accompanying drawing and enforcement are combined, the utility model is elaborated further.

Embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated:

As shown in Figure 1 and Figure 2, prevent in door by 1-4 intelligent anti-theft device, with 1-2 door handle level place, 1-4-2 power switch should first close by user before going out, then is shut by 1-1 door.Now 1-4-1 supply module is that whole system is powered, the now angular velocity data of 2-1 three-axis gyroscope Real-time Collection door, the acceleration information of 2-2 three axis accelerometer Real-time Collection door, magnetic field strength date under environment residing for 2-3 tri-axle magnetometer Real-time Collection door, the data collected are sent in 1-4-3 single-chip microcomputer, 1-4-3 single-chip microcomputer uses Kalman filtering algorithm to carry out filtering and noise reduction to the door acceleration information collected and angular velocity data, ellipse fitting rectification is carried out to the magnetic field data collected simultaneously, finally, nine number of axle after process export according to being fused to Eulerian angle accurately by 1-4-3 single-chip microcomputer.Eulerian angle change is now small, and within the threshold range being stabilized in 1-4-3 single-chip microcomputer inner setting.1-4-3 Micro Controller Unit (MCU) driving 1-4-7 dual-colored LED lamp presents green simultaneously; If do not have personnel to invade for a long time, 1-4-3 single-chip microcomputer enters low power consumpting state automatically.

When house has personnel to invade, 1-4-3 single-chip microcomputer triggered interrupts, wake up from low power consumpting state, the now door angular velocity data that collects of 2-1 three-axis gyroscope, all there is larger change in the door acceleration information that 2-2 three axis accelerometer collects and the magnetic field strength date that 2-3 tri-axle magnetometer collects, 1-4-3 single-chip microcomputer is by merging nine number of axle certificates this moment, the Eulerian angle exported after transforming change a lot, Eulerian angle change is now far beyond the threshold range set by 1-4-3 single-chip microcomputer inside, now 1-4-3 Micro Controller Unit (MCU) driving 1-4-7 dual-colored LED lamp presents redness, 1-4-5 buzzer warning, 1-4-3 single-chip microcomputer is sent short messages to user in time by driving 1-4-9GPRS module simultaneously, inform that user house is stolen.

When house does not have personnel to invade, and user is when needing to open door, only 1-4-10 user mobile phone need be connected with the 1-4-8 bluetooth module in 1-4 intelligent anti-theft device, when the password inputted with 1-4-10 family mobile phone and 1-4-8 bluetooth module match password consistent time, the each pin of 1-4-3 Micro Controller Unit (MCU) driving is low level, device quits work, and can open 1-1 door.

When user wants this intelligent anti-theft device to rework, only the 1-4-4 reset key be connected with 1-4-3 single-chip microcomputer input end need be pressed.

The above is the preferred embodiment of the present invention, under the prerequisite not departing from the technology of the present invention principle, can also make some improvement and distortion, and these improve and distortion also should be considered as protection scope of the present invention.
