该公母插头转接板包括塑料外壳804、与电源适配器相连接的第一接线端803,其中第一接线端803包括输入端引脚805和806。与电动车的电池连接的第二接线端812。第二接线端812包括输出端引脚807和808。对应于每一组检测接线端的指示灯802和控制开关801。The male-female plug adapter board includes a plastic shell 804 and a first terminal 803 connected to the power adapter, wherein the first terminal 803 includes input pins 805 and 806 .

The single-chip microcomputer (first main control unit) reads the value of the current acquisition unit 101 through the A/D conversion module and performs data processing. The male-female plug adapter board has 4 charging channels on the board, which can detect the charging status of four charging devices in real time at the same time.

充电电路连接好后(即将电源适配器一端连接在图9供电排插的插座上,将另一端连接在公母电路转接板的第一接线端803,将第二接线端812连接到电动车的充电插孔),按下公母插头转接板上对应通道的充电开关(控制开关),主控单元1中单片机检测到按键控制电路中对应按键按下,对应通道的指示灯亮起。与此同时,如图5所示,主控单元1通过DL-20无线串口透传模块向主控单元2发送通道检索命令(第二提示信息),即依次闭合断电插排中的继电器,查找能够使充电设备工作的插孔。每次闭合继电器后,经过一段时间的延时,若电流检测模块中的电流采集单元101检测到充电电路中有电流,其给出一个模拟电压值,经A/D转换模块将模拟量转换成数字量后发送给单片机1。此时,也说明主控单元2此时闭合的继电器通道是正确的,主控单元1即向主控单元2发送该通道正常工作的信号(第三提示信息),主控单元2将停止检查其他通道,并保持该通道继电器闭合。After the charging circuit is connected (that is, one end of the power adapter is connected to the socket of the power supply strip in Figure 9, the other end is connected to the first terminal 803 of the male-female circuit adapter board, and the second terminal 812 is connected to the electric vehicle. charging jack), press the charging switch (control switch) of the corresponding channel on the male-female plug adapter board, the single-chip microcomputer in the main control unit 1 detects that the corresponding button is pressed in the button control circuit, and the indicator light of the corresponding channel lights up. At the same time, as shown in Figure 5, the main control unit 1 sends a channel search command (second prompt information) to the main control unit 2 through the DL-20 wireless serial port transparent transmission module, that is, sequentially closes the relays in the power-off socket, Find an outlet that will allow the charging device to work. After closing the relay each time, after a period of delay, if the current acquisition unit 101 in the current detection module detects that there is current in the charging circuit, it will give an analog voltage value, and the analog value will be converted into After the digital quantity is sent to the single chip microcomputer 1. At this time, it also shows that the closed relay channel of the main control unit 2 at this time is correct, and the main control unit 1 sends a signal (the third prompt message) that the channel is working normally to the main control unit 2, and the main control unit 2 will stop checking other channels, and keep the channel relay closed.

同时主控单元2将与该通道对应的继电器序号发送给主控单元1,主控单元1将公母插头转接板上的插头通道与断电排插中的继电器序号(也即插孔序号)对应起来,并通过EEPROM电路存储到EEPROM中。下次充电时,按下公母插头转接板上的充电开关后,主控单元1会首先检测与该通道配过对的继电器控制插孔,如果充电设备未能正常工作,说明断电插排上的插孔改变了,此时则清除上次存储的配对信息,重新检测,重新配对,重新保存配对成功后的通道信息。At the same time, the main control unit 2 sends the relay serial number corresponding to the channel to the main control unit 1, and the main control unit 1 compares the plug channel on the male-female plug adapter board with the relay serial number (that is, the jack serial number) in the power-off strip. ) correspondingly, and stored in the EEPROM through the EEPROM circuit. When charging next time, after pressing the charging switch on the male-female plug adapter board, the main control unit 1 will first detect the relay control jack that has been paired with this channel. If the charging device fails to work normally, it means that the power-off plug If the jack on the row is changed, the pairing information stored last time will be cleared, re-detected, re-paired, and the channel information after successful pairing will be saved again.

如图9所示,断电排插包括外壳901,插孔902和911(插孔902和插孔911是为了适应不同的插头,如三孔插头或者两孔插头,而设计),指示灯903及主控单元2。下面以插孔911为例,说明断电排插内部的结构,在断电排插内部,火线905引出线与多路继电器906的接入端子907相连,多路继电器906的输出端子908与两插孔911的引脚909相连,两插孔911的引脚910与零线904相连。当主控单元2收到充电完成信号时即断开充电设备与市电的连接。As shown in Figure 9, the power-off strip includes a shell 901, jacks 902 and 911 (the jacks 902 and 911 are designed to adapt to different plugs, such as three-hole plugs or two-hole plugs), and an indicator light 903 and main control unit 2. Taking the jack 911 as an example, the internal structure of the power-off strip is described below. Inside the power-off strip, the outgoing line of the live wire 905 is connected to the access terminal 907 of the multi-way relay 906, and the output terminal 908 of the multi-way relay 906 is connected to the two The pins 909 of the jacks 911 are connected, and the pins 910 of the two jacks 911 are connected with the neutral line 904 . When the main control unit 2 receives the charging completion signal, it disconnects the charging device from the mains.

充电完成后,主控单元1检测到充电电流达到充满电时的电流阈值后,向主控单元2发送充电完成信号,主控单元2接收到该信号后,断开该通路的继电器,也即将充电设备与市电断开,其它通道保存原状态不动作。After the charging is completed, after the main control unit 1 detects that the charging current reaches the current threshold when fully charged, it sends a charging completion signal to the main control unit 2. After receiving the signal, the main control unit 2 disconnects the relay of the path, which is The charging equipment is disconnected from the mains, and the other channels keep the original state and do not operate.

总体来说,参见图4,本实施例的方案实施的流程为:上电初始化,当按下公母插头转接板上对应通道按键时,主控单元1通过DL-20无线串口透传模块向主控单元2发出闭合继电器命令,充电设备接通,开始给电池充电,同时该通道的充电指示灯亮起。充电设备恒压充电时,电池的充电电流逐渐减小,减小到一定值后即认为充电完成。内嵌于公母插头转接板中的电流检测模块实时检测通路中的电流值大小,经AD转换得到数字量并发送给主控单元1,主控单元1将检测到的电流值大小与阈值电流进行比较,达到阈值电流时即通过无线透传模块向主控单元2发送断开继电器的命令,指示灯熄灭,充电结束。该装置能够有效地防止蓄电池过冲,节约电能,延长充电设备的使用寿命,提高用电安全性。In general, referring to Fig. 4, the implementation process of the scheme of this embodiment is: power-on initialization, when pressing the corresponding channel button on the male-female plug adapter board, the main control unit 1 passes through the DL-20 wireless serial port transparent transmission module A command to close the relay is issued to the main control unit 2, the charging device is connected, and the battery starts to charge, and at the same time, the charging indicator light of the channel is on. When the charging equipment is charging at a constant voltage, the charging current of the battery decreases gradually, and the charging is considered to be completed when it decreases to a certain value. The current detection module embedded in the male-female plug adapter board detects the current value in the channel in real time, and the digital value is obtained through AD conversion and sent to the main control unit 1. The main control unit 1 compares the detected current value with the threshold value The currents are compared, and when the threshold current is reached, a command to disconnect the relay is sent to the main control unit 2 through the wireless transparent transmission module, the indicator light goes out, and the charging ends. The device can effectively prevent the battery from overcharging, save electric energy, prolong the service life of the charging equipment, and improve the safety of electricity use.

The circuit shown in Figure 11 is integrated in the charging panel shown in Figure 12, similar to the circuit principles shown in Figure 6 and Figure 7, and the current detection and relay control are completed by the single-chip microcomputer STC89C52RC. Since the current detection and the control of the relay are all completed in the single chip microcomputer, it does not need to communicate information, so there is no need to connect a communication unit. The functions of the power supply circuit, crystal oscillator circuit, reset circuit, button control circuit, indicator light circuit, and EEPROM circuit shown in FIG. 11 are the same as those in FIG. 6 above, and will not be repeated here.

图12中所示的充电面板是主要针对手机、笔记本电脑的充电设备提出的多通道自动断电节能保护装置。因这些充电设备的公母插头体积较小,采用图10所示集中、小型化的方案,将公母插头转接板与断电插排结合在一起,组合成自动断电智能排插(充电面板),并将图6和图7中的DL-20无线串口透传模块用实际的信号线取代,将两个主控单元用一个主控单元代替,(其电路图参看图11),来实现电流检测、插孔配对、自动断电的功能。The charging panel shown in FIG. 12 is a multi-channel automatic power-off energy-saving protection device mainly proposed for charging equipment of mobile phones and notebook computers. Because the male and female plugs of these charging devices are small in size, the centralized and miniaturized solution shown in Figure 10 is adopted to combine the male and female plug adapter boards with the power-off socket to form an automatic power-off smart socket (charging Panel), and replace the DL-20 wireless serial port transparent transmission module in Figure 6 and Figure 7 with actual signal lines, and replace the two main control units with one main control unit (see Figure 11 for its circuit diagram) to realize Current detection, jack pairing, automatic power off functions.

The charging panel corresponds to a charging energy-saving protection device for charging a mobile phone, including a charging interface 121 (i.e. Jack for providing commercial power), a current detection interface composed of the first detection interface 122 and the second detection interface 124 . When charging the mobile phone, it needs to be realized through the power adapter and 2 charging cables. Specifically, when charging the mobile phone, plug the power adapter into the charging interface 121, connect the USB interface of a charging line to the power adapter, connect the other end to the first detection interface 122 on the panel, and connect the other end to the charging interface 122.

Specifically, when charging a computer, one end of the power adapter is plugged into the charging interface corresponding to the power adapter of the computer (that is, the three-pin jack on the charging panel), and the other end is connected to the first detection interface 126 on the panel. Connect one end of another charging cable to the second detection interface 127, and connect the other end to the charging interface of the computer to charge the computer. You can refer to the above method when charging other devices such as ipad, so I won’t go into details here.

The first detection terminal in this embodiment The circuit structure between the interface and the second detection interface is the same as the circuit structure between the first terminal and the second terminal in the above embodiment. This embodiment combines the power strip and the automatic power-off energy-saving protection device together, realizing the miniaturization and portability of the equipment.
