50、ocess 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

51、 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 compared to the R0 and R1 is equal to the main chip when the dial-up alarm,

52、if not equal is not to alarm re-tested. 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. CONCLUSIONBy the cooperation of using of temperature and smoke

53、 sensors, through detecting the temperature and smoke on-site, 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 reliabil

54、ity of warehouse more than the former single equipment of fire alarm, and prevent failing of reporting and misinformation.
