Embodiment

Below in conjunction with accompanying drawing the utility model is done further to specify.

Like Fig. 1, shown in Figure 2; A kind of honeycomb fashion security monitoring module of the utility model; Comprise air-sensitive concentration testing circuit 1 and central processing unit control circuit 2; The output signal of said air-sensitive concentration testing circuit 1 transfers to central processing unit control circuit 2 through voltage amplifier circuit 11, and the output signal controlling of said central processing unit control circuit 2 is sent to ZigBee wireless module circuit and driving circuit 22, and the output signal of said ZigBee wireless module circuit 21 sends to data processing centre (DPC) 211.

Said air-sensitive concentration testing circuit 1 adopts UL-281 gas sensor QM to gather gas concentration signal, and it belongs to the heater-type semiconductor devices, and CO gas is had high sensitivity; Variation to environment temperature and humidity has good stable property, the termination power of said UL-281 gas sensor QM, and the other end is through resistance R 5, R1 ground connection; IC2, R6, R2, R3 etc. form voltage amplifier circuit, when UL-281 gas sensor QM is high resistant when 1M ohm is above, when the CO gas leakage reaches finite concentration; The resistance of UL-281 gas sensor, anxious brush descends, and it is big that the voltage amplification factor of voltage amplifier circuit IC2 becomes; The voltage of its output strengthens thereupon, because the setting value of the 2nd pin in-phase end reference voltage of voltage amplifier circuit IC2, when the CO gas concentration surpasses setting value; The 1st pin output high level signal of voltage amplifier circuit IC2, this signal is held through the 21st pin I/O that resistance R 7 is input to 89C52 single-chip microcomputer IC1, after 89C52 single-chip microcomputer IC1 internal processes is judged; By 89C52 single-chip microcomputer IC1 the 26th pin output high level, through resistance R 8 current limlitings, transistor Q1 conducting; Relay J 1 adhesive, its contact J1-1 is by transferring normally closed point normal battle to, and contactor M gets; Start exhaust blower and carry out exhaust ventilation, avoid personnel to poison indoor; Another road output is formed ZigBee wireless module circuit 21 by the 6th, 7 ends of ZM2410 wireless communication module IC3 and the 10th, 11 ends of 89C52 single-chip microcomputer IC1; ZM2410 wireless communication module IC3 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, the receiving sensitivity up to the power output of 7dBm and-100dBm can satisfy telecommunication; Send the AT instruction by 89C52 single-chip microcomputer IC1 ZM2410 wireless communication module IC3 is realized wireless data transceiving; Switch pin with the RS-485 direction, send current failure message to data center, this module is the honeycomb fashion networking; Has distance, low cost and other advantages.

An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
