Design And Implementation Of Deyang City Nadu Logistics Company Warehouse Fire Early Warning System

Modern logistics companies warehouse in storage goods sort is various, exist agreat risk of fire, for effective control the risk of fire, need to adopt efficient advancedfire alarm system. Along with the development of computer technology, informationtechnology and control technology and the widespread application, intelligent controltechnology and the great progress of disaster prevention and control technology, modernfire warning system to mode use of smoke, temperature, gas fire detection of sensitivefactor to fire prevention and control and the warning.DeBang logistics Co. LTD is the national5A comprehensive service logisticsenterprise, main domestic highway transportation and airfreight forwarding servicenetwork. With the increase of freight traffic volume, product kinds of complex, forDeBang logistics company freight transit security requirements of the warehouse alsohas greatly improved, especially the fire prevention, and a kind of high efficiency, stable,intelligent fire warning system is necessary.In order to improve the DeBang logistics company deyang branch freight relaywarehouse fire safety, this paper designed a fire warning system based on enhanced51single-chip microcomputer, with enhanced51SCM STC89C52as the controller chip,design a high precision, high level of integration, low power consumption of intelligentfire alarm system. By the environment temperature, smoke concentration as judge of thefire, the basis of the completion of the fire warning. Mainly consist by the single chipmicrocomputer control module, clock module, smoke concentration measurementmodules, DS18B20temperature measurement modules, sound and light alarm module,TFT true color display module and power source module. This system use STC89C52as the next place machine, complete data acquisition, processing and the field devices tojudge the control. The design of a warehouse fire alarm system has higher reliability and stability, high accuracy, the different types of fire has high sensitivity, but also reducethe false alarming.
