Abstract
The utility model relates to an alcohol concentration detecting device. The detecting device comprises an alcohol sensor circuit and a single chip microcomputer control circuit, wherein the signals collected by the alcohol sensor circuit are transmitted to the single chip microcomputer control circuit through a high-power switch circuit; the output signals of the single chip microcomputer control circuit are transmitted to a Zigbee wireless module circuit; and the output signals of the Zigbee wireless module circuit are sent to a data processing center. The alcohol sensor circuit is used for collecting an alcohol signal, and after the alcohol signal is judged by the single chip microcomputer control circuit, a Zigbee wireless module is driven to send an alarm message to an alarm center to remotely monitor the use and storage conditions of the alcohol to avoid a fire. The detecting device is a new-generation wireless transmission alarm device which realizes simple networking, low cost and reliable performance.

Description of drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
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 alcohol concentration sniffer of the present utility model, comprise alcohol sensor circuit 1 and single chip machine controlling circuit 2, the signal that described alcohol sensor circuit 1 is gathered is transferred to single chip machine controlling circuit 2 through high-power switching circuit 11, the output signal of described single chip machine controlling circuit 2 is sent to ZigBee wireless module circuit 21, and the output signal of described ZigBee wireless module circuit 21 sends to data processing centre (DPC) 211.
Described alcohol sensor circuit 1 adopts QMNJ9 alcohol gas sensor IC1 to gather alcohol signal, the output terminal of described QMNJ9 alcohol gas sensor IC1 connects potentiometer W, when if QMNJ9 alcohol gas sensor IC1 detects alcohol and reaches finite concentration, resistance decreasing between the A-B of QMNJ9 alcohol gas sensor IC1 then, the sliding end current potential of potentiometer W raises.When this current potential is elevated to 1.6V, TWH8778 high-power switch device IC2 connects, the 18th pin I/O end that is input to 2051 single-chip microcomputer IC3 through resistance R 3 current limlitings also is high level state, after 2051 single-chip microcomputer IC3 internal processors are judged, by the 6th of ZM2410 wireless communication module IC4, the 2nd of 7 ends and 2051 single-chip microcomputer IC3,3 ends are formed ZigBee wireless module circuit 21, ZM2410 wireless communication module IC4 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 ZM2410 wireless communication module IC4 is realized wireless data transceiving, switch pin with the RS-485 direction, send warning message to data center, the use of the on-the-spot alcohol of remote monitoring with deposit situation, avoid the generation of fire.
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.
