Realization principle of smoke detector
The base of the smoke detector is provided with 4 conductor pieces, and a connecting terminal is arranged on the piece, and the positioning card is not arranged on the base, so that the direction of the detector alarming and confirming lamp can be adjusted conveniently. The detector buses in the wiring tube are connected to each of the two terminals of the diagonal (regardless of polarity), and the other pair of conductor pieces are used to assist the fixed detector.In short, the smoke detector or comparison in the life of the place, a lot of convenience to our life, to guarantee a very good for our security, we make the process more perfect.
Because the system is ultimately oriented to end users, and users generally do not understand technical details, but also do not need to understand, the user is directly exposed to the software's running interface. Based on the function of system, users often through the operation of simple interface and operation process complexity, section if there is a good consistency, whether can facilitate the development of two standard to evaluate a system's quality. From the programmer's point of view, programs that can be easily maintained and upgraded are dynamic. Therefore, based on the realization of the basic functions, how to provide users with a simple, comfortable, friendly interface, how to make users convenient and simple operating system, how the existing basis to facilitate the realization of maintenance and upgrade software, how to make the support for the two development of the modern system is easy. The software design goals.
Smoke detectors in inside and outside the ionization chamber inside the radioactive americium 241, positive and negative ion generation, under the electric field respectively to the positive and negative electrode movement. Under normal conditions, the internal and external ionization chambers are stable in both current and voltage. Once a smoke Cuantao outside the ionization chamber. Interfere with the normal movement of charged particle current, voltage will change, destroy the balance between internal and external ionization chamber, and a wireless transmitter sends wireless alarm signal to the receiving host notification from afar, the alarm message.
The smoke detector is mainly through monitoring the concentration of smoke to achieve fire prevention, smoke detectors, the internal use of ion smoke sensor, ion smoke sensor is a kind of advanced technology, stable and reliable operation of the sensor, is widely used in all kinds of fire alarm system, fire alarm performance is far better than the gas sensing resistance type.
