Embodiment Construction

[0033] Below with reference to accompanying drawing, the present invention will be further described by example.

[0034] Refer to attached figure 1 to attach Figure 7, a vibration accumulative alarm method, the vibration accumulative alarm method includes the following steps: (1) vibration detection: the vibration sensor converts the sensed vibration into a vibration electrical signal for processing and then transmits; (2) human body scanning: adopts infrared human body scanning to actively emit infrared rays The signal covers the scanning area, and the returned infrared signal is processed. According to the strength of the signal, it is divided into three states: strong signal, weak signal and no signal. Among them, when there are people in the scanning area, a strong scanning signal is obtained, and there is no one in the scanning area. In the case of scanning weak signal, the weak signal is the basic signal, indicating that the human body scanning is working normally. Wh...

Abstract

According to the invention, a vibration accumulated alarm method and apparatus are provided, featuring the accumulation of vibrations detected in a period. The method comprises the following steps: 1) vibration detection in which a vibration sensor converts the vibrations it senses into electric signals of vibration and transmits the electric signals after processing; 2) signal processing and logic determination in which the electric signals of vibration experience basic processing and conversion into pulse signals of vibration, followed by the determination of the effectiveness of the pulse signals and the determination that effective pulse signals are effective vibration signals; 3) signal accumulation in which the effective vibration signals confirmed by logic determination in a period or rather, an accumulation period, are accumulated according to their times; and 4) alarm making in which an alarm is made when the times of the effective vibration signals accumulated in an accumulation period reach a set alarm threshold value.

Description

technical field [0001] The invention relates to the technical field of vibration alarms, in particular to a method and device for accumulating vibrations detected in a cycle and accumulating vibrations. Background technique [0002] Vibration anti-theft alarm, referred to as vibration alarm, has the characteristics of high sensitivity, convenient installation and use, and low cost, and has a wide range of applications in anti-theft warnings. The vibration alarm is to identify the detected vibration signal, and when the vibration signal strength reaches the alarm threshold, an alarm is issued. Some vibration alarms will trigger the alarm no matter what the vibration is. Most of the existing vehicle alarms use the first vibration to send out a reminder sound, and the second vibration in a short period of time will trigger the alarm. Man-made vibrations and natural vibrations cannot be filtered, so Frequent false alarms from vehicle alarms have become a major source of sound p...
