火灾自动报警系统毕业论文中英文资料外文翻译文献
nal electronic fire alarm system relies on sensors to automatically detect a fire and trigger an alarm。which can alert people on the scene or notify the authorities through a special electric cable。Over the years。the development of alarm devices has led to a wide range of ns for different ns。particularly in the civil domain.
One popular type of alarm system is the infrared alarm。which has gained n due to its ability to detect fires without us infrared signals。making it more secure。Infrared sensors can be classified into two types: light survey and hot survey。based on their n mechanisms.
To improve the effectiveness of fire alarm systems。many modern devices also incorporate advanced technologies such as wireless n。remote monitoring。and intelligent analysis。These features enable faster response times and more accurate n。which can potentially save lives and minimize property damage in the event of a fire.
Overall。the development of fire alarm systems has greatly improved fire safety in us settings。from homes to commercial buildings。As technology continues to advance。we can expect even more sophisticated and reliable alarm systems to emerge in the future.
and is commonly used in thermal imaging cameras and temperature measurement devices。It has a fast response speed。high sensitivity。and good n characteristics。However。it requires cooling and is not very convenient to use。nally。the sensitivity of the component and the wavelength of the infrared n are important factors to consider.
The hot n sensor。on the other hand。uses the electricity effect to detect infrared n。When the sensor receives an increase in temperature due to infrared n from the target。certain physical quantities within the sensor change。allowing for the n of infrared n。This type of sensor can operate at room temperature and is commonly used in us ns such as surveillance systems and fire n devices.
In summary。infrared n aids play a crucial role in us industries and ns。While there are different types of sensors available。each with their own advantages and ns。it is importan
t to consider factors such as sensitivity。wavelength。and temperature requirements when selecting the appropriate sensor for a specific n.
The sensitivity of the n is very high and the response speed is quick。nally。it is not dependent on the infrared n wavelength and can only detect the background n limit。making it a very convenient n。This article presents the design of a passive infrared n aid。The article mainly elaborates on the principle of the infrared n aid。the content of the hot release。and the characteristics of the electric detector alarm circuit。as well as the BISS0001 signal processor and 555 timers。Finally。the hardware electric circuit for the hot release infrared n alarm apparatus is designed and completed.
With the widespread use of fire in modern households。electricity n has increased。and the frequency of home fires has risen。In the event of a fire。it is often difficult to control the flames due to a lack of firefighting equipment and panicked individuals。This can lead to significant loss of life and property。Therefore。it is important to understand the characteristics of household fires and take preventative measures.
Preventing domestic fires and cing fire losses is of great practical significance。To achieve this。it is essential to have proper fire n measures in place。These measures include installing smoke detectors。having fire extinguishers readily available。and educating family members on fire safety.
In n to preventative measures。it is important to understand the characteristics of household fires。These fires often start in the kitchen due to cooking accidents or electrical ns。They can also occur in bedrooms due to faulty wiring or the improper use of heating devices。Understanding these factors can help individuals take proactive steps to prevent fires from occurring.
