Embodiment:
Below in conjunction with embodiment, further illustrate the utility model.
See Fig. 1-Fig. 5, the utility model comprises one group of distributed control device, described distributed control device communicates with master control device, described distributed control device comprises microprocessor one, described microprocessor connects pyroelectric sensor, smoke transducer, optoelectronic switch, audible-visual annunciator one, wireless transceiver one, valuables alarm and display circuit one respectively, described master control device comprises microprocessor two, and described microprocessor two connects wireless transceiver two, audible-visual annunciator two and display circuit two respectively.
The input equipment of distributed control device mainly comprises pyroelectric sensor, smoke transducer, optoelectronic switch, input keyboard, display circuit one and valuables alarm.The detecting distance farthest of pyroelectric sensor is greater than 5m, achieves the human detection of about 5m scope; Smoke transducer can detect the smog of inflammable gas and 300 to 10000ppm scopes effectively, realizes exception safety situation signal alarm during fire; The maximum correlation detection width of optoelectronic switch is 5m, is detected by the priority of two groups of optoelectronic switches, and the situation completing human body turnover detects, and data is stored in the inner EEPROM of ATmega16, and then achieves number record function; Input keyboard, achieves the correlation function by key control and the police of password solution.
Described microprocessor one and microprocessor two all adopt ATmega16 single-chip microcomputer.Adopt ATmega16 single-chip microcomputer as main control chip.Advantage: AVR is high speed embedded scm, has high speed, low consumption, secret advantage.Its inner integrated aboundresources, has powerful Timer/Counter and A/D translation function and communication interface.
Described wireless transceiver one and described wireless transceiver two adopt ZigBee wireless module.ZM2410 in ZigBee wireless module can realize point-to-point communication and communicate with point-to-points, and we configure a ZM2410 respectively by main frame with from machine, just can realize the radio communication between slave.Its working frequency range is 2.4GHz, has the transfer rate of 250kbit/s, 500kbit/s, and wireless transmission distance, and can self-organizing network in a kilometer range, and transmission data stabilization is reliable.

System needs 3.3v, 5v, 12v high-quality voltage source, according to another technical documentation
r3select 1k metalfilmresistor,
r1the accurate adjustable resistance of 15k is selected to modulate above-mentioned voltage.
Accumulation of energy inductance selected is the design key of switching power circuit.Gauge tap blocking interval just produces back electromotive force and provides energy to load, and therefore, the electric current flowing through load only flows through 1/4th of energy storage inductor electric current.
(K closes short front moment)
Output current in formula
i o for flowing through the electric current of load, work as dutycycle
dwhen=0.5, its size equals maximum current
i lM 1/4th;
tfor the work period of Switching Power Supply,
tjust in time equal 2 times
t on .Try to achieve thus:
(
