The Analysis And Design Of Environmental Monitoring And Alarm System Based On NRF24L01

With the development of science and information technology, the development of the military information construction is changing all the time. The integrated joint operations of the land, sea and air forces become the new mode of future war so that supply will become the key military targets in the war. Warehouse in the rear of the army, as the basis of strategic materials reserves, to undertake the military supplies, weapons, ammunition, medical, food, and camp and other kinds of military products of receiving, storage, distribution, and transportation task. By means of modern science and information technology, the new solution will strengthen warehouse management and improve the quality of goods and materials storage.Due to the characteristics of strong concealment, large storage area requirement, warehouse usually located in the mountains and using underground structure. The location will affect the quality of stock material because of the internal factors and external factors. External factors include heat, light, oxygen, moisture, corrosive substances, microorganisms, insect, rat, etc. Because the warehouse is located in the mountains, day and night temperature difference is large. The military supplies in the warehouse are mainly all kinds of weapons and ammunition, most of them are of metal materials. Through comprehensive analysis, temperature, humidity, smoke become the most important storage problem.In this paper, we use Microcontroller STC89C52 and the whole solution is based on demand analysis and the principle of modular and hierarchical design. We used the combination of a variety of equipment and control software into a warehouse environment quality monitoring alarm system. Mainly includes the gas concentration detection module, wireless communication module, alarm module, display module, GSM SMS module, keys module. The system will open the gas in the testing room when the harmful gas concentration is higher than the set value, alarm, room temperature is not higher than the set value, the smoke concentration is higher than the threshold, the control system will automatically open the ventilation in the room, reduce the concentration of the warehouse and harmful gas, and through the GSM short message sent via wireless network the corresponding situation to warehouse manager/When the manager received the warehouse after testing environment information, he can the environmental situation in time.
