技术资料 一种共享单车智能检测系统的设计与实现
“互联网+”时代,共享单车在给人们出行带来便利的同时也逐渐暴露出诸多问题,如乱停乱放、随便出入各公共场所、运营维护不到位等,这些问题严重扰乱了社会公共秩序。基于此,本文以STC89C52单片机为核心,利用无线通信原理,设计了一个共享单车智能检测系统。该系统的实施不仅可以解决单车乱停乱放、随便进出公共场所的问题,而且 ...
数据结构 Many applications use connection/object pool. A program may require a IMAP connection pool and LDAP
Many applications use connection/object pool. A program may require a IMAP connection pool and LDAP connection pool. One could easily implement a IMAP connection pool, then take the existing code and implement a LDAP connection pool. The program grows, and now there is a need for a pool of threads. ...

技术资料 基于单片机的AB门双门联动互锁系统设计
本文系统的介绍了适合公安系统以及银行等本身具有特殊性场所的双门门禁控制系统的原理与设计。这个系统以单片机作为控制核心,指纹识别、人脸识别等多种形式作为开门的识别钥匙,使得整个系统小巧,节省空间。该系统在节约经济成本的情况下,却可以有效的提高安防系统的安全可靠性。This paper systematically introduces the p ...
技术资料 基于单片机可语音控制和报时的数字时钟的设计
以STC89C516单片机为主机,STC11L08XE单片机为从机,在传统按键控制式数字时钟的基础上加入语音识别模块和语音合成模块,实现了可语音控制和语音报时的功能。该时钟除具有计时功能外,还具有整点报时、询问报时和闹钟功能;既可用按键控制,也可通过人机对话的形式语音控制。经测试,语音识别率可达75%。不仅适用于广场、车站、客 ...
技术资料 基于单片机控制的智能环保垃圾桶设计
本文设计了一种基于STC89C52单片机控制的智能环保垃圾桶,该垃圾桶采用可充电的直流电池供电(12V),不仅可以实现自动开盖,解决人们扔垃圾时双手的卫生问题,并且还能有效地把垃圾中的金属自动分类和回收,达到减少环境污染和节约资源的目的。垃圾桶下方由寻轨小车承载,用于整个垃圾桶的自动寻轨移动,适用于大型的公共场地(例如: ...
技术资料 基于单片机小车自动掉头控制系统设计
针对部分小区及公共场所小车掉头难的问题,提出了以STC15F2K60S2单片机为控制核心,以车灯作为掉头控制信号的小车自动掉头控制系统,利用超声波传感器检测小车是否到达转盘,由光敏电阻传感器检测小车的车灯控制信号,通过单片机识别处理,启动电机带动转盘匀速旋转180°,驾驶员无须下车,就能轻松实现小车原地掉头,无需人工操作。 ...
