【正文】 and other external devices. EX1 wiring diagram shown in figure 4, The PD4 pin to connect the main chip HTO , the module began to dial alarm when PD4 output high level signal, PD5 connection ON / OFF pin input is high level signal to open the dialup settings, the input does not work when this pin bee low, ERR pin connected to PD6 pin of MCU, PD6 output 1 begun to test whether the telephone line failure, READY pin connect MCU PD7 pin detection and alarm is pleted, the alarm is end when PD7 pin is high . Figure 4. EX1 wiring diagram IV. SOFIW AREDESIGN start ATmega16 Initialize N whether there are smoke signals? Y R0=1 collection temperature signal whether the N alarm value? Y R1=1 dialup alarm READY=1? Y Figure 5. The main program flow chart Because in the early stages of fires and the smoldering phase will produce a large number of aerosol particles and smoke particles .In the stage of incipient fire substances in the bustion process produces a lot of heat, so should make the smoke sensor and temperature sensor used in conjunction, first with the smoke sensor detects whether there is smoke generation, then the temperature sensor detects the temperature, temperature sensor alarm value is set to 50 degrees. When the smoke is detected R0 is 1, not smoke R0 is 0. Then test the temperature when the temperature reaches the value of seasonal early warning R1 is 1, the value of seasonal temperature not to reach an early warning R1 to 0, at this time pared to the R0 and R1 is equal to the main chip when the dialup alarm, if not equal is not to alarm retested. This smoke sensor and temperature sensor used in conjunction with greatly improved the reliability of detection to prevent the omission of false positives, program flow diagram shown in Figure 5. V. CONCLUSION By the cooperation of using of temperature and smoke sensors, through detecting the temperature and smoke onsite, the automatic alarm system could find any fire in warehouse and send the message to managers of warehouse in the early time by the form of short messages. So its application could greatly reduce fire losses and enhanced the safe reliability of warehouse more than the former single equipment of fire alarm, and prevent failing of reporting and misinformation. The system has a high reliability, low price and high sensitivity.
