Intelligent anti-theft alarm device

Abstract

The invention discloses an intelligent anti-theft alarm device. The intelligent anti-theft alarm device comprises a CAN-bus (Controller Area Network-Bus) communication circuit A, a central processor unit B, a reset circuit C, a crystal oscillator circuit D, a matrix key circuit E, a data storage circuit F, a nixie tube display circuit G, a buzzer alarm circuit H and a relay control circuit I, wherein the central processor unit B, the matrix key circuit E and the data storage circuit F form a main circuit; the CAN-bus communication circuit A performs data communication with other anti-theft nodes; the buzzer alarm circuit H and the relay control circuit I perform alarm functions; the nixie tube display circuit G performs a digital display function; and the reset circuit C and the crystal oscillator circuit D provide the necessary support for work of a single chip processing unit F. The intelligent anti-theft alarm device has the advantages of strong anti-interference and error-correcting capabilities and clear superiority in the aspects of communication capability, reliability, real-time property, flexibility, usability, long transmission distance, low cost and the like.

Description

Technical field: [0001] The invention relates to an alarm device, in particular to an intelligent anti-theft alarm. Background technique: [0002] Although the anti-theft alarms of the prior art are of many types, the deficiency in use is that all adopt the RS-485 data communication bus. It is mainly reflected in the fact that there are many limitations in the RS-485 data communication bus itself. With the development of science and technology, the RS-485 data communication bus has low efficiency, poor real-time performance of the system, low reliability of communication, high post-maintenance costs, and complex network engineering debugging. , The transmission distance is not ideal, the number of nodes that can be connected to a single bus is small, and the shortcomings of inflexible applications are gradually exposed. Invention content: [0003] The purpose of the present invention is mainly to overcome the shortage of the above design of the traditional anti-theft alar...
