来电、停电报警电路的分析
摘要
电是一种无污染、易转化、优质高效的能源,广泛应用于国民经济和社会生活中,已成为经济社会发展的重要支柱。随着电子产品的增多,对电能的需求量也在与日俱增,但由于电力的供应不足和电路故障,停电的事情时有发生。一但市电供应中断,对人们的生活和生产都造成很大的损失,此时如果不加以及时补救,经济损失就在所难免。而来电、停电报警器便能在市电停电或来电时,及时的提醒人们尽早的采取相应的补救措施来减少经济损失。这次论文论述几种常见报警电路的工作原理,并依据经济、可靠、实用,易于集成化,小型化的原则,对来电、停电多功能报警器作详细的分析说明。对于多功能来电、停电报警器,在停电或来电时,信号通过电源电路、数字逻辑电路和控制输出电路,从而使报警器鸣报警;在市电正常或停电期间,不报警;在发生紧急事故时,报警器报警。在电力重要并且紧缺的今天,使来电、停电报警器向多功能、集成化、小型化发展,还有很多的研究工作,所以具有广阔的发展前景。

Abstract
Electricity is a kind of non-pollution, easy conversion, high quality and efficiency energy, it is widely used in pilation of economic and social lives, and it has e an important pillar of economic and social development. With the electronic products increase, increasing demand for energy, but as a result of the electric power insufficient supply and the electric circuit break down, the power cutting sometimes occurs. Once the mains interrupt, it will cause great damage to people's life and production, if our action is not timely remedial, economic loss is unavoidable. The ing telegram or blackout alarm will power when mercial power e and fail, it timely remind people as soon as possible to take corresponding remedial measures to reduce the economic loss. This article discusses mon alarm circuit principles of work, and according to the economy, reliable, practical, easy integration, militarization, principle of power is to make calls, a detailed analysis of the multi-functional alarm. For multifunctional power alarm, electricity normal or cut, in power or power supply circuit, signals through digital logic circuit and control the output circuit, thereby alarm bell alarm, The normal mains or during the blackout in, alarm. In the event of an emergency, the alarm gives an alarm. In
