Intrusion alarm system and method based on P-S wave detection

Abstract

The invention discloses an intrusion alarm system and method based on P-S wave detection, and belongs to the technical field of alarm devices. The system comprises three detectors and a receiving alarm, and is characterized in that the detectors are used for receiving P-wave and S-wave signals, and each detector comprises a probe, a filter detector, an analog-to-digital converter and a Beidou positioning module; and the receiving alarm is connected with the three detectors through data lines, and is used for carrying out distance measurement and positioning on the P-S wave signals, sending out alarm sound or vibration and displaying an invasion direction. The method specifically comprises the steps that the detector receives a P-S wave signal and sends the P-S wave signal to the receiving alarm, and the receiving alarm carries out distance measurement and positioning on the P-S wave signal, gives out alarm sound or vibration and displays the invasion direction. The system and the method are used for discovering dangers in advance during field camping or camping.

Description

Technical field [0001] The present invention particularly relates to an intrusion alarm system and method for P-S wave detection based on belonging to the technical field warning device. Background technique [0002] With the improvement of living standards of the people, camping has become an increasingly common way of life, but the risk of an accident ensuing camping is also increasing year by year, the attacks have occurred criminals when camping or beast , which became some of the lingering psychological shadows of people camping. [0003] Similarly, when soldiers camping in order to prevent the enemy or wild animal attack suddenly, often need to send the alert sentry guard, but because of the fierce battle against the inevitable emergence of fatigue at night guard, false love leakage prone situation, the enemy can take advantage of of the machine, especially when a single soldier camp, in the case without the aid of other tools, adequate rest and a high degree of vigilance o...

Problems solved by technology

[0003] Similarly, when soldiers camp in the wild, in order to prevent sudden attacks by enemies or wild animals, they often need to send sentries to stand guard. However, due to the fierce confrontation on the battlefield, fatigue is inevitable when standing guard at night, and misunderstandings are prone to occur. Especially when a single soldier camps, without the help of other tools, it is often impossible to have adequate rest and a high degree of vigilance, which is very dangerous for soldiers
