技术领域
本发明涉及车辆识别技术领域,特别涉及一种无线电子开关装置。
背景技术
目前,采用电池供电的控制方法大都采用开关方式,需要人为控制,需要时开启电源,不需要时关闭电源;因此出现的问题是自动化程度低、人的工作量大、效率低、浪费能源、成本高。
发明内容
针对现有技术存在的不足,本发明提供一种无线电子开关装置,用以解决电池供电控制的问题。
本发明的硬件包括电源模块、无线接收模块;其中电源模块与无线接收模块相连。
本发明的连接关系是:电感线圈L1一端连接到三极管Q3的发射极,L1的另一端通过电容C14、二极管D7连接到Q3的基极;Q3的集电极通过电阻R25连接到三极管Q4的基极,Q4的发射极与接口J1的1针及三极管Q7的发射极相连,J1与9V电源相连;Q4的集电极通过二极管D9、电阻R28串联后再与电容C16的并联电路与三极管Q8的基极相连,电容C17的两端分别与D9、R28的公共端及电源地相连;电阻R29的一端与C16、R28及Q8的基极的公共端相连,另一端与电源地相连;Q8的集电极通过电阻R26与三极管Q7的基极相连;Q7的集电极输出电压;在Q3的集电极与地之间连接有无线接收模块的按钮开关S1,在Q3的基极与地之间连接有电容C15。
本发明的工作包括电子开关导通与断开。
电子开关的导通是:无线接收模块中的按钮开关S1为常开开关,当S1闭合时,由三极管Q4、Q8、Q7组成的电子开关处于导通状态,Q7的集电极输出电源电压;一般情况下,S1为常开状态,由三极管Q3、Q4、Q8、Q7组成的电子开关处于断开状态;当有外来长波信号时,电感L1会接收外来信号感生压降,使三极管Q3导通,Q3导通后Q4、Q7、Q8也导通,即自动接通电子开关,Q7的集电极输出电源电压。
电子开关的断开是:无线信号产生的电磁场消失,电感L1上的感生压降为0V,由电容C15、C16、C17、二极管D9、电阻R28、R29组成的延时电路使三极管Q4、Q7保持一段时间的导通状态,当电容放电结束后,电源电路中的三极管Q3、Q4、Q7、Q8都处于截止状态,电子开关自动断开,系统停止工作。
本发明的优点是利用无线电信号控制电源工作,具有节能、环保、使用方便、自动化程度高的特点。

本发明的工作包括电子开关导通与断开。
电子开关的导通是:无线接收模块中的按钮开关S1为常开开关,当S1闭合时,由三极管Q4、Q8、Q7组成的电子开关处于导通状态,Q7的集电极输出电源电压;一般情况下,S1为常开状态,由三极管Q3、Q4、Q8、Q7组成的电子开关处于断开状态;当有外来长波信号时,电感L1会接收外来信号感生压降,使三极管Q3导通,Q3导通后Q4、Q7、Q8也导通,即自动接通电子开关,Q7的集电极输出电源电压。
电子开关的断开是:无线信号产生的电磁场消失,电感L1上的感生压降为0V,由电容C15、C16、C17、二极管D9、电阻R28、R29组成的延时电路使三极管Q4、Q7保持一段时间的导通状态,当电容放电结束后,电源电路中的三极管Q3、Q4、Q7、Q8都处于截止状态,电子开关自动断开,系统停止工作。
