应当说明的是，本发明实施例中的数据线可以基于传统的四芯或者多芯数据线(如包括但不限于USB数据线)的基础，通过设置电压检测电路6 和/或电流检测电路7于传统数据线的电压线上来检测手机充电时实时流过的电压和/或电流，并经DSP芯片5接收后推送至显示屏4实时显示，从而实现手机充电时对流经数据线的电压和/或电流实时监控，能够及时发现隐患并排除，降低手机充电过程中的损坏概率。
可以理解的是，第一连接端子1连接外部设备的接口类型包括但不限于USB-TYPE-A、USB-TYPE-B；第二连接端子2连接手机的接口类型可根据手机不同接口，设置不同的类型，包括但不限于micro USB、micro USB转Lightning、micro USB转USB-TYPE-C。显示屏4为液晶屏或其它屏。
在一个实施例中，两芯数据通信线31分别设置为DM、DP，两芯电压线32分别设置为VCC、GND，第一连接端子1外部设备的接口类型为USB-TYPE-A，第二连接端子2连接手机的接口类型为micro USB，显示屏4为液晶屏；此时，电压检测电路6并接在两芯电压线32之中的VCC线上，电流检测电路7串接在两芯电压线32之中的GND线上，DSP芯片5采用具有MCU的功能芯片。
在另一个实施例中，两芯数据通信线31分别设置为DM、DP，两芯电压线32分别设置为VCC、GND，第一连接端子1外部设备的接口类型为USB-TYPE-A，第二连接端子2连接手机的接口类型为micro USB转Lightning，显示屏4为液晶屏；此时，电压检测电路6并接在两芯电压线32之中的VCC线上，电流检测电路7串接在两芯电压线32之中的GND线上，DSP芯片5采用具有MCU和蓝牙通信的功能芯片。例如DSP芯片5的型号为MS1793，其上设有分别与电压检测电路6和电流检测电路7相连的ADC针脚，与显示屏4相连的GPIO和I2C针脚，并集成有蓝牙通信功能。
在本发明实施例中，如图3所示，为了避免手机充电时高压脉冲漏到手机端而造成手机充电系统的损坏，本发明实施例中的数据线还包括设置于本体L内部的稳压电路8，该稳压电路8的一端与电压检测电路6并接于同一芯电压线32上，另一端接地。
同理，为了避免手机充电时长时间过压或过流对手机充电系统的损坏，在本发明实施例中的数据线还包括设置于本体L内部的过压及过流保护电路9；其中，该过压及过流保护电路9串接于连接第一连接端子1和电压检 测电路6之间的一芯电压线32上，实现与第一连接端子1和电压检测电路6相连，且该过压及过流保护电路9还与DSP芯片5的第四端a4相连，使得流经电压线32上的电流超过预设的电流阈值时，通过DSP芯片5切换第一连接端子1与第二连接端子2之间的连接，或者流经电压线32上的电压超过预设的电压阈值时，在一定时间内自动将电压调整至电压阈值，且不降低输出功率，并在超出一定时间后，通过DSP芯片5切换第一连接端子1与第二连接端子2之间的连接。
同理，为了避免手机充电时高温对手机充电系统的损坏，在本发明实施例中的数据线还包括设置于本体L内部的温度检测电路10，该温度检测电路10与DSP芯片5的第五端a5相连，在本发明实施例中的数据线温度过高时，通过DSP芯片5切换第一连接端子1与第二连接端子2之间的连接。

其中，该稳压二极管ZD101与电压检测电路6并接于两芯电压线32之中的VCC线上，该稳压二极管ZD101是一种超大功率的瞬态抑制二极管，当电压高于6V/14V时，会瞬间导通，将高于6V/14V的能量进行释放；该过压/过流保护芯片SGM2525串接在两芯电压线32之中的VCC线上，并通过VCC线与第一连接端子1和电压检测电路6实现连接，同时还连接DSP芯片5接收过压过流保护指令；该温度传感器NTC101连接DSP芯片5，将采集的温度送至DSP芯片5。
在本发明实施例中，如图4所示，电压检测电路6包括相串接的第一分压电阻61和第二分压电阻62；其中，第一分压电阻61的一端接入两芯电压线32之中一芯上，另一端与第二分压电阻62的一端串接形成串接端并与DSP芯片5的第一端a1相连；第二分压电阻62的另一端接地。在一个实施例中，第一分压电阻61的阻值为1MΩ，第二分压电阻62的阻值为100KΩ，且第一分压电阻61接入两芯电压线32之中的VCC线上，第二分压电阻62接地，让DSP芯片5采集到1/11的电压。
在本发明实施例中，如图5所示，电流检测电路7包括相并联的采样电阻71和集成式运算放大器芯片72；其中，采样电阻71还串接在两芯电压线32之中另一芯上，实现与第一连接端子1和第二连接端子2相连；集成式运算放大器芯片72还与DSP芯片5的第二端a2相连。应当说明的是，集成式运算放大器芯片72可以避免元器件过多而缺乏合理的安装空间。在一个实施例中，集成式运算放大器芯片72的型号为SGM8477，采样电阻71的阻值为1Ω，该采样电阻71串接在两芯电压线32之中的GND线上。
如图6所示，为本发明实施例中的数据线的内部系统结构的电路应用图。图6中，USB-TYPE-A为第一接线端子1，用于连接电脑、充电器等；micro USB为第二接线端子2，用于连接手机；
在USB-TYPE-A和micro USB之间设置的1-4条连线为连接线3，其中，2-3分别对应为两芯数据通信线31的DM、DP，1、4分别对应为两芯电压线32的VCC、GND；
稳压二极管ZD101形成稳压电路8；芯片U103形成过压及过流保护电路9；温度传感器NTC101形成温度检测电路10；
电阻R108为第一分压电阻61、电阻R109为第二分压电阻62，且电阻R108和R109形成电压检测电路6；
电阻R111为采样电阻71、芯片U104为集成式运算放大器芯片72，且电阻R111和芯片U104形成电流检测电路7；当然，还有多个滤波电容C129和C130等；
液晶屏CON108为显示屏4；
芯片MS1793为DSP芯片5，该芯片MS1793的PA3/ADC3针脚连接电压检测电路6，PA7/ADC7针脚连接电压检测电路7；PA4/ADC4、EN、VCP等针脚连接过压及过流保护电路9；PA0/ADC0针脚连接温度检测电路10；T2C_SCL、T2C_SDA针脚连接显示屏4。
实施本发明实施例，具有如下有益效果：
1、在本发明实施例中，由于电压检测电路和电流检测电路设置在数据线的两芯电压线上，通过DSP芯片将电压检测电路和电流检测电路所采集的电压和/或电流实时传递给显示屏进行显示，从而能在手机充电时对流经数 据线的电压和/或电流进行实时监控，及时发现隐患并排除，降低手机充电过程中的损坏概率；
2、在本发明实施例中，由于在数据线的两芯电压线上还设有稳压电路，可以避免高压脉冲漏到手机端而造成手机充电系统的损坏；
3、在本发明实施例中，由于在数据线的两芯电压线上还设有过压及过流电路，当电压或电流过高时会主动断开两芯电压线的连接，可以避免过压或过流造成手机充电系统的损坏；
4、在本发明实施例中，由于在数据线的两芯电压线上还设有温度检测电路，当温度过高时会主动断开两芯电压线的连接，可以避免高温造成手机损坏。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
