Abstract

The utility model relates to a multifunctional alarm, comprising a vibration probe circuit and a single-chip microcomputer control circuit, wherein output signals of the vibration probe circuit are transmitted to the single-chip microcomputer control circuit through a trigger module circuit; output signals of the single-chip microcomputer control circuit are transmitted to a ZigBee wireless module circuit; and output signals of the ZigBee wireless module circuit are transmitted to a data processing center. When a connecting line to a host is detected to be broken or a trigger signal is detected in a vibration module in a detector, by the aid of the determination of the single-chip microcomputer control circuit, the multifunctional alarm drives the ZigBee wireless module circuit to send alarm information to an alarm center.

Description

A kind of multifunction antitheft device

Technical field

The utility model relates to a kind of alarm, particularly be a kind of multifunction antitheft device.

Background technology

Modern society, security precautions technology is more and more important, along with intelligentized progressively ripe, burglar alarm on the market is more and more, but these burglar alarm warning complex structures, function singleness also are easy to generate and phenomenon such as fail to report, and are difficult to adapt to the growing market demand.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, a kind of multifunction antitheft device of the present utility model, involving vibrations probe circuit 1 and single chip machine controlling circuit 2, the output signal of described vibration probe circuit 1 is transferred to single chip machine controlling circuit 2 through trigger module circuit 11, the output signal of described single chip machine controlling circuit 2 is transported to ZigBee wireless module circuit 21, and the output signal of described ZigBee wireless module circuit 21 is sent to data processing centre (DPC) 211.

Described vibration probe circuit 1 is encapsulated in to mould in the shell by vibration probe MD 62k Ω in parallel resistance R 1 and constitutes; when in case vibration takes place in protected object; vibration probe MD namely exports a short-circuit signal to the 3rd pin of vibration detection module I C1; this moment, the 1st pin voltage of vibration detection module I C1 sported 3V by normal 2.25V; its the 5th pin is just exported high level signal; this signal is input to the 18th pin I/O end of 2051 single-chip microcomputer IC3; after the comprehensive judgement of 2051 single-chip microcomputer IC3 internal processes; by the 6th of 2M2410 wireless module IC2; the 2nd of 7 ends and 2051 single-chip microcomputer IC3; 3 ends are formed ZigBee wireless module circuit; 2M2410 wireless module IC2 is the embedded serial ports transparent transmission of the Zigbee of built-in 2.4GHZ (some multiple spot and point-to-multipoint) communications protocol; support aerial upgrade firmware or configuration far module information; up to the output of the power of 7dBm and-receiving sensitivity of 100dBm; can satisfy telecommunication; send the AT instruction by 2051 single-chip microcomputer IC3 2M2410 wireless module IC2 is realized wireless data transceiving; switch pin with the RS-485 direction, send warning message to data center.

If probe is destroyed with the main frame line, the 3rd pin of vibration detection module I C1 becomes low level by high level, its the 2nd pin is just exported high level, after the comprehensive judgement of 2051 single-chip microcomputer IC3 internal processes, send the AT instruction by 2051 single-chip microcomputer IC3 2M2410 wireless module IC2 is realized wireless data transceiving, switch pin with the RS-485 direction, send warning message to data center.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
