Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides an alarm, including: the device comprises a main controller, an inclination sensor, a vibration detection circuit and a buzzer;

the main controller is used for starting the buzzer to give an alarm after receiving an inclination threshold signal of the inclination sensor;

the buzzer is further connected with the main controller through a vibration detection circuit, the vibration detection circuit is used for amplifying vibration signals generated when the buzzer does not give an alarm, and the main controller is further used for starting the buzzer to give an alarm based on the amplified signals.

Specifically, when the angle of the installed product changes, such as a door lock and the like, when the angle reaches a threshold value by sensing the inclination (the rotating angle) during rotation, the main controller sends an alarm by controlling the buzzer. When the product of being installed is suffering by the destruction action such as strike, cutting, thereby the bee calling organ makes copper sheet (buzzing piece) warp because external environment vibrates, there is piezoelectric material on the copper sheet because the deformation of copper sheet, thereby export a weak voltage at piezoelectric material output side, input the corresponding detection pin of master controller after vibration detection circuit enlargies the filtration, make the level change, thereby awaken up the master controller and control bee calling organ and carry out corresponding warning, thereby realized the warning of two kinds of detection forms of vibration and rotation, the cost is lower when expanding alarming function, the consumption is also lower.

As a feasible realization way of the embodiment, the diameter of the buzzer sheet of the buzzer is 27mm, and the frequency is 4 KHz. The volume is maximum when the frequency output by the corresponding pin of the master controller is close to 4K. The tilt sensor is a steel ball vibration sensor or a mercury switch. When the steel balls in the steel ball vibration sensor are positioned at different positions, the steel balls are communicated with the shell and the copper sheet of the other pin of the sensor, namely the on-off state of alarming, so that the main controller is caused to detect the pin and interrupt the level change, signals are identified, and the buzzer is controlled to give corresponding alarming.

In order to further optimize this technical solution, as shown in fig. 2, some embodiments of the present invention further include: and the booster circuit is connected between the buzzer and the main controller and is used for driving the buzzer to give an alarm. When alarming, the voice alarm signal provided by the main controller is boosted to more than 30V, so that the buzzer piece deforms the copper sheet due to the piezoelectric effect, the copper sheet deforms periodically, the air is pushed from the surface to transmit a wave signal, and the human ear can hear a high-level sound to play a role in alarming.

The battery pack, the battery pack and the master controller are connected to provide 3V direct current voltage for the battery pack to supply power.

Wherein the battery pack is formed by connecting 2 to 6 button batteries in series or in parallel. In the specific implementation process, a button battery of 160MA/1.5V can be adopted, so that only two batteries are connected in series to provide voltage meeting the normal work of each part. Two button batteries can be used for 3 months according to the alarm once a day, thereby saving power consumption.

And the detection switch is connected between the main controller and the battery pack and is used for controlling the on-off of the alarm signal. Wherein the detection switch is a Hall magnetic switch. The main controller enters a working state after the switch is pressed, when a product is in a static state, the main controller can automatically enter a low power consumption state when a vibration and rotation signal is not detected, the working current is less than 5uA, and after an alarm is triggered, the main controller is recovered for 15 seconds and enters the low power consumption state. And stopping working when the key is touched again.

Referring to fig. 3, in another embodiment of the present invention, the main controller uses a domestic MCU, XR6080 is compatible with PIC12F508-E/SN, and is a low-cost, high-performance, 8-bit, fully static, flash-based CMOS single chip, which uses RISC architecture and has only 33 single word/single cycle instructions. All other instructions except the program jump instruction (two cycles) are single cycle (200 ns). The performance of the XR6080 device is much higher than that of the same product at the same price. A 12-bit wide instruction is highly symmetric such that it is twice as code intensive as a comparable 8-bit single chip machine. An instruction set that is easy to use and easy to remember greatly reduces development time. XR6080 products are also equipped with special features that can reduce system cost and power consumption. Power-on reset (POR) and Device Reset Timer (DRT) eliminate the need for external reset circuitry for the device. There are four oscillator configurations that can be selected, including the INTRC internal oscillation mode and the power-saving LP (low power) oscillation mode. The power saving sleep mode, watchdog timer and code protection function increase the cost, power consumption and reliability of the system.

The boosting circuit is a boosting inductor and is controlled by the main controller to boost, the boosting inductor L1 uses a plug-in 3-pin boosting inductor to boost a voice alarm signal provided by the MCU singlechip to more than 30V, so that the buzzer deforms the copper sheet due to the piezoelectric effect, the buzzer deforms periodically, air is pushed from the surface to transmit a wave signal, and the human ear can hear a high-level sound.

Z1 is steel ball vibration sensor, and the vibration detection circuit comprises Q3, R3, R5, C2, R4, constitutes filter circuit by C2 and R4 and carries out voltage signal's filtering, then sends into the corresponding pin of singlechip and handles after carrying out corresponding the amplification by Q3 triode.

The detection switch adopts an HAC248 magnetic switch to carry out on-off control of the work of the singlechip.
