power_platform
- 本文将总结我们公司所设计的各种电源电路,从中提炼出我们公司的电源平台,供大家参考。 我们通常用到的工作电压为12V和5V。12V主要用来驱动继电器工作或蜂鸣器,在本平台中将用+12表示;5V将用+5表示。在应用中,也用到24V和3V电源,分别用+24和+3表示。3V一般用在有电池做备用电源的场合。 -This paper will summarize our company designed the power supply circuit, from which we extract

- 每次先由消费者输入账号密码,如输入正确则调出该用户的账户,显示该用户的余额;然后由工作人员输入消费额,我的改进之处就在此处:当员工输入的金额小于10元时,消费机自动扣除相应的金额 而若员工输入的金额大于10元时,消费机就会一直报警(蜂鸣器一直响),直到用户按键确认后,消费机才会扣除相应的消费额。通过这种改进,我们就能有效地避免工作人员因漏输小数点而造成打卡错误的情况。-Enter the account password every time start with the consumer, s

- 火灾报警电路是利用两个温度传感器输出的差值来判断室内是否有火灾,然后运用的是一个差分放大电路,根据实际需要,我们可以适当的改变放大的倍数,这样可以避免温漂使设计的产品更有实用性。接着使用的是一个单限电压比较器,这样可以选择性的让危险电压值通过,最后实现报警。在报警的时候,首先会运用一个发光二极管,在电压达到一定值的时候,发光二极管就会伴同蜂鸣器一起工作,一边发光一边有声音,达到报警的作用。-Fire alarm circuit is the use of the difference betwe
