The Air Regulating System In The Arsenal

Abstract: The arsenal is a locale that can store armaments and ammunitions. As the special weaponery materials, armaments and ammunitions are strict to their desposited surroundings.The former temperature and humidity control system of arsenal is temperature and humidity measurement and control system of computer, which is composed of the traditional temperature and humidity sensors. The output signals of temperature and humidity sensors are changed the signals that the computers can identify through the transducers (voltage or current signals). Moreover the power supply and input interface of the corresponding simulative quantums are supplied by the system for sensors. At the same time, it is strict to the distance of signal transmission and electromagnetic disturbance, especially during many measurement points, the above-mentioned problems are more prominent. This can not only improve the cost, but also reduce the reliability of the system.The digital, networking and intelligent sensors based on micro-processor technique adopt to particular transmitted structure of 1-wire bus, which can expediently and shortcutly set up networks of sensors and introduce the brand-new concept in order to observe and control systematic construction. This new and high technology is used, and the digitized ITU temperature and humidity environmental monitoring system are designed in this passage. Adopting the advanced chip science and technology of American DALLAS company, combining the on-the-spot situation of China and using the technology of the intelligent on-the-spot bus, only there is digital signal transmission in the whole system. And the sensor and gathering module can interlink internet, which makes the system more reliable and is more convenient to connect up.Collecting the manufacturing technology of the electric and electronic device, the electricity of the electric and electronic circuit varies technology, the vector of exchanging electrical machinery varies the control technology, the new and high technology, such as technology, and the microcomputer and large scale integrated circuit, etc. of PWM (pulse width modulated)are large scale in one suits of exchange frequency converters, have already become the main produt of electric transmission trade. Amount of wind turned into that this subject uses frequency conversion to adjust the speed technology ventilator controlled.
