Description

数显可调感应距离垃圾桶控制装置 技术领域
本实用新型涉及一种生活垃圾容器，特别是一种数显可调感应距离垃圾桶控制装置。
背景技术
现有技术的红外感应垃圾桶，其感应距离多为不可调整。障碍物和感应窗口的距离大于临界感应距离时不触动感应开盖，障碍物和感应窗口的距离小于临界感应距离时感应被触动开盖，在业界称为临界感应距离，简称为感应距离。目前市场上的红外感应垃圾桶其感应距离一般用手掌测试感应距离在25cm左右，在实际应用中，有的人站着使用(希望感应距离高不要弯腰)，有的人坐着使用(希望感应距离适中)，有的人将感应垃圾桶置于台面下使用(希望感应距离低不容易产生误动作)，由于个性化使用要求不同，单一的、固定的感应距离的技术方案已经无法满足市场个性化需求。中国专利号名称为：一种可设定感应距离的感应翻盖垃圾桶及其控制方法(专利申请号：201710309082.1)提供了一种调整感应距离的技术方案，然而，其调整时需要通过一边按设定键，一边感应手的距离进行设定，操作很不方便，且容易受到感应者自身晃动和外界环境影响，调整的距离也不够直观，使用者无法便捷地知道当前的设定距离。
发明内容
本实用新型的目的在于根据现有技术的不足之处而提供一种能够根据个性化需求调整感应距离、操作简单、快捷、直观的数显可调感应距离垃圾桶控制装置。
本实用新型的目的是通过以下途径来实现的：
数显可调感应距离垃圾桶控制装置，包括有发射器、接收管、放大器、模数转换器、模数转换结果寄存器、比较单元、感应距离可调寄存器、微电脑控制单元和驱动电路，接收管通过放大器、模数转换器连接到模数转换结果寄存器，模数转换结果寄存器与感应距离可调寄存器的输出端分别连接比较单元，微电脑控制单元的一输出端连接驱动电路，微电脑控制单元的控制端分别连接模数转换结果寄存器、比较单元、感应距离可调寄存器和发射器，其结构要点在于，还包括有数码显示管和按键，按键的输入端与微电脑控制单元连接，微电脑控制单元的另一输出端与数码显示管连接，按键输入的信号通过微电脑控制单元处理，并获得一感应距离值作为感应距离可调寄存器的寄存值，同时微电脑控制单元将该感应距离值或者代表该感应距离值的数字信息输出到数码显示管进行显示。
上述按键可以进一步具体为：
所述按键为数字输入键，能够直接输入数值，通过微电脑控制单元转换处理后，存储到感应距离可调寄存器中。
或者是，所述按键是选择输入键，此时感应距离可调寄存器中存储有多个设定距离的存储单元，或者在微电脑控制单元中存储有多个设定距离，按键操作时其按键内容或者按键次数能够对应选择相应的设定距离，从而在感应距离可调寄存器中选择设定的存储单元作为当前基准寄存器，或者将从微电脑控制单元中选定的设定距离作为感应距离存储到感应距离可调寄存器中。
当按键为数字按键，则每个数字按键代表一个选择值(选择设定的感应距离)；当按键为单一的按键，则根据按键的次序递进选择，在初始值情况下，每按一次则递进选择下一个次序的选择值，达到最后选择值后，返回到第一个次序的选择值。感应距离可调寄存器或者微电脑控制单元中存储有可供选通的设定距离值与按键值或者按键次序一一对应。
所述数码显示管能够显示当前的感应距离值，或者感应距离值的代表值，例如10cm的代表值为1。此时，按键的每次操作将使数码显示管显示对应的数字，因此操作简单、方便、快捷，不受外界影响，单手即可操作，且使用者能够通过数码显示管非常直观地知道当前的感应距离，使用无障碍，能够满足市场个性化需求。
本实用新型可以进一步具体为：
模数转换器、模数转换结果寄存器、感应距离可调寄存器、比较单元和微电脑控制单元集成在同一微电脑控制芯片内；所述微电脑控制芯片包括第一端口4A、第二端口4B、第三端口4C、第四端口4D和第五端口4E，第一端口4A与发射器相连，第二端口4B与放大器的输出端相连，第三端口4C与数码显示管相连，第四端口4D与驱动电路相连，第五端口4E与按键相连。
所述发射器为红外线发射器，接收管为红外线接收管。模数转换结果寄存器接收到的是当前感应到的实际距离，比较单元将该实际距离与感应距离可调寄存器中的值进行对比，当满足设定要求时，比较单元将信号通过微电脑控制单元传送给驱动电路，驱动电路依次经电机、减速器连接至所述桶盖，用以驱动桶盖进行开关盖动作。
所述数码显示管为个数数字显示器，显示1～N个数字，其中2≤N≤9。
按一下按键显示当前感应距离档位，之后每按一下按键数码显示管显示数字加1，当达到最高感应距离N档后，再按一下数字返回为1档重复上述循环。所述数码显示管显示1表示感应距离为10cm；数码显示管显示2表示感应距离为20cm；数码显示管显示3表示感应距离为30cm；数码显示管显示4表示感应距离为40cm；数码显示管显示5表示感应距离 为50cm；数码显示管显示6表示感应距离为60cm；数码显示管显示7表示感应距离为70cm；数码显示管显示8表示感应距离为80cm；数码显示管显示9表示感应距离为90cm。数码显示管可以安装在感应窗口下方。
综上所述，本实用新型提供了一种数显可调感应距离垃圾桶控制装置，通过按键直接输入或者选择设定的感应距离，通过数码显示管直观显示当前的感应距离，使用者能根据自己的需求和使用环境的要求以输入或者选择的方案调整感应距离的高度，因此操作简单、方便、快捷，不受外界影响，单手即可操作，且使用者能够通过数码显示管非常直观地知道当前的感应距离，使用无障碍，能够满足市场个性化需求。

下面结合附图和实施例对本实用新型做进一步描述，但并不是对本实用新型的限定。
具体实施方式
最佳实施例：
参照附图1和附图2，数显可调感应距离垃圾桶控制装置，包括红外线发射器1、红外线接收管2、放大器3、微电脑控制芯片4、模数转换器41、模数转换结果寄存器42、感应距离可调寄存器44、比较单元43、微电脑控制单元45、数码显示管5、按键6、驱动电路7、电机8、减速器9、桶盖10、感应窗口11和感应区12，所述的数显可调感应距离垃圾桶的控制方式为主动式红外线感应方式。模数转换器41、模数转换结果寄存器42、感应距离可调寄存器44、比较单元43和微电脑控制单元45集成在微电脑控制芯片4内；所述微电脑控制芯片4包括第一端口4A、第二端口4B、第三端口4C、第四端口4D和第五端口4E。第一端口4A与红外线发射器1相连，第二端口4B与放大器3的输出端相连，第三端口4C与 数码显示管5相连，第四端口4D与驱动电路7相连，第五端口4E与按键6相连。驱动电路7依次经电机8、减速器9连接至所述桶盖10，用以驱动桶盖10进行开关盖动作。红外线接收管2依次经所述放大器3、模数转换器41、模数转换结果寄存器42连接至比较单元43，所述比较单元43还与感应距离可调寄存器44相连。
本实施例以感应距离分为5档调节为例，数码显示管5显示1～5，分别对应1～5档，显示“1”时感应距离为10cm；显示“2”时感应距离为20cm；显示“3”是感应距离为30cm；显示“4”时感应距离为40cm；显示“5”时感应距离为50cm。在微电脑控制芯片上电时默认感应距离30cm，在待机状态下程序扫描按键6是否被按下，如果按键6未被按下感应距离保持默认值30cm；如果按键6被按下，数码显示管5显示当前值为“3”，之后每按一下按键数码显示管显示数字加1，当达到最高感应距离5档后，再按一下按键显示数字返回1档，重复上述循环，如按到某一档时不再按下按键6，该档的数字显示2秒后熄灭(为了达到省电的目的)，该档位对应的感应距离值，通过显示数字查表程序赋值(即从微电脑控制单元中选通对应的感应距离值并赋值给感应距离可调寄存器44)完成调节。之后比较单元43通过比较模数转换结果寄存器42的当前值和感应距离可调寄存器44中的感应距离值来触动桶盖10是否开启，当模数转换结果寄存器42的值小于感应距离值时桶盖7不开启；当模数转换结果寄存器42的值大于感应距离值时桶盖开启。障碍物和感应窗口11的距离越远，反射回来的信号越小；障碍物和感应窗口11的距离越近，反射回来的信号越大，所设定的感应距离越远，反射回来的信号越小。
本实施例的数码显示管5与微电脑控制芯片4连接电路图参见图2，数码显示管5采用一位LED七段数码显示管，LED七段数码显示管的7个引脚通过限流电阻R1～R7分别与微电脑控制芯片4的4C1～4C7端口连接，数码显示管5安装于感应窗口下方。
以上所述仅为本实用新型实施例，凡依本实用新型申请专利范围所做的均等变化与修饰，皆应属本专利的涵盖范围。
本实用新型未述部分与现有技术相同。
