Real-time anti-theft alarm system for detecting magnetic field intensity fluctuation of Hall effect

Abstract

The invention relates to a real-time anti-theft device, in particular to a real-time anti-theft alarm system for detecting magnetic field intensity fluctuation of Hall effect, which consists of a high-intensity permanent magnet, a Hall magnetic field intensity probe and an information processing terminal, wherein the high-intensity permanent magnet is arranged on the moving end of a detected carrier; the Hall magnetic field intensity probe is arranged on the fixed end of the detected carrier; the Hall magnetic field intensity probe can detect the magnetic field intensity fluctuation of the high-intensity permanent magnet; and the Hall magnetic field intensity probe is electrically connected with the information processing terminal. The system can effectively avoid the defects of alarm system failure caused by strong magnet interference through a magnetic field intensity detection mode, and can effectively realize the close range and real-time remote monitoring. All the information of state change of the detected object is stored on a monitoring platform, the real-time data of the detected object can be clear on a computer of a user, effective real-time data are provided for the user, the cost of enterprises is reduced, and effective management is realized.

Description

technical field [0001] The invention relates to a real-time anti-theft alarm device, in particular to a real-time anti-theft alarm system of Hall effect magnetic field intensity fluctuation detection type used for anti-theft of automobile fuel tanks, automobile batteries, automobile doors and building door and window switches. Background technique [0002] The existing anti-theft devices all use magnetic switches for alarm detection probes. This alarm device uses a switch, that is, a permanent magnet is placed on the door or the carrier to be detected. When the carrier moves and the permanent magnet leaves a certain distance, The reed switch is disconnected or the Hall switch is activated, and the alarm system starts, but if the thief knows that this type of probe is used, then as long as a strong magnet is used to interfere, the reed switch or Hall switch is always closed, then, The alarm system will fail. Contents of the invention [0003] The technical problem to be so...
