The shock detector is mainly used to detect the vibration signal generated during the destruction activity to trigger the alarm. The vibration sensor is the core component of the vibration detector. Commonly used vibration detectors include mechanical displacement sensors, electric speed sensors, piezoelectric crystal acceleration sensors, and the like.
Consumer and commercial intelligent burglar alarm triggers alarm on induction vibration
Home smart burglar alarms are often required to detect ankles, drills, burrows, blows, and displacements to make an alarm. They can be used to open or lift a safe, such as a bank teller machine to drill a hole or open a hole, to open a hole in a vault door, and Doors, windows, walls, roofs, equipment, file cabinets, electric retractable doors These need to use vibration-induced detection.
The shock detector is mainly used to detect the vibration signal generated during the destruction activity to trigger the alarm. The vibration sensor is the core component of the vibration detector. Commonly used vibration detectors include mechanical displacement sensors, electric speed sensors, piezoelectric crystal acceleration sensors, etc.
Mechanical displacement sensors commonly have mercury type, steel ball type. When subjected to shock and vibration, mercury beads and steel balls will leave their original position and trigger an alarm. This sensor has a small control range and is suitable for small-scale applications such as doors, windows, safes, and partial walls. Steel ball type has a larger range than mercury.
Speed ​​sensors generally use electric sensors, based on the principle of electromagnetic induction, consisting of permanent magnets, coils, springs, dampers and housings. That is, when a moving conductor cuts magnetic lines of force in a fixed magnetic field, electromotive forces are induced at both ends of the conductor. Therefore, a sensor manufactured using this principle is called an electric sensor. This kind of sensor has high sensitivity, large detection range and good stability, and the processing technology has a relatively high price and relatively high price.
The accelerometer is generally a piezoelectric accelerometer. The accelerometer uses piezoelectric material to generate a charge due to mechanical deformation caused by vibration. The magnitude of the vibration is judged by the magnitude of the charge, and the sensitivity is adjusted by the circuit.
When the vibration detector is installed and used, it should be firmly installed with the detection surface. Otherwise, it is not easy to feel the vibration. Do not install the vibration detector near the alarm so as to avoid overtones within the detection response frequency range. Do not get close to the water pipe. If the water pipe comes in contact with a protective object, the water flow will generate interference signals. Do not go near electric equipment such as fans, air conditioners, etc., otherwise it may cause mechanical vibration.
