電子密碼鎖的設(shè)計(jì)


摘   要
　　　近年來，隨著改革開放的深入發(fā)展，電子電器的飛速發(fā)展.人民的生活水平有了很大提高。各種高檔家電產(chǎn)品和貴重物品為許多家庭所擁有。然而一些不法分子也是越來越多。這點(diǎn)就是看到了大部分人防盜意識還不夠強(qiáng)。造成偷盜現(xiàn)象屢見不鮮。因此，越來越多的居民家庭對財(cái)產(chǎn)安全問題十分擔(dān)憂。
有報警功能的密碼鎖這時正為人們解決了不少問題.但是市場上的密碼鎖大部分都是用于一些大公司財(cái)政機(jī)構(gòu)。價格高昂,一般人們難以接受。如果再設(shè)計(jì)和生產(chǎn)一種價格低廉、性能靈敏可靠的密碼鎖，必將在防盜和保證財(cái)產(chǎn)安全方面發(fā)揮更加有效的作用。
　　　由于電子密碼鎖是一種通過密碼輸入來控制電路或是芯片工作的，從而控制機(jī)械開關(guān)的閉合，完成開鎖、閉鎖任務(wù)的電子產(chǎn)品。它的種類很多，有簡易的電路產(chǎn)品，也有基于芯片的性價比較高的產(chǎn)品?，F(xiàn)在應(yīng)用較廣的電子密碼鎖是以芯片為核心。

ABSTRACT
    Recent years, along with reform and open policy thorough development, electronic appliance's upscale electrical appliances product and the valuables have for many families. Howeswiftdevelopment. People's living standard had the very big enhancement. Each kind of ver some unlawful elements are also more and more. This sees majority of person security consciousness also insufficient. Creates steals the phenomenon to be common. Therefore, more and more resident families worried to the property security problem. The alarm apparatus had been solving many problems by now for the people. But in the market alarm apparatus majority of use in some big company fiscal  institution. The price is soaring, generally the people accept with difficulty. If redesign sand produces one kind moderately-priced, the performance keen reliable burglar alarm, will certainly plays a more effective role in security and the guarantee property security aspect.
　　　As the electronic code lock is a password to enter the control circuits, or chips, so as to control mechanical switches closed, the completion of the lock, closed the task of electronic products. It's a lot of species, there is a simple circuit products as well as chip-based products more cost-effective. Now a wider application of electronic locks is at the core chip.
