目前，随着无人机在农业上的应用越来越成熟，越来越多的农场、林场或牧场等开始使用无人机进行植保作业。在利用无人机进行植保作业时，由于作业面积大，而无人机的续航能力有限，故无人机需要进行多次充电才能完成植保作业。但由于部分植保作业地区较偏远，难以找到市电，通常需要携带内燃发电机为充电器供电，然后通过充电器为无人机的电池充电。此过程中，因传统的内燃发电机无法直接为无人机进行充电，故必须佩戴充电器，增加搬运劳动强度。同时由于无人机标配的内燃充电系统的供电电源为市电，通常为220V的交流电，导致内燃发电机的选择受到限制。
为了解决内燃发电机在充电应用中搬运不方便的问题，本公开提出了一种内燃充电系统。下面，结合具体实施例进行说明。
请参见图1至图3是本公开的一实施例，提供的一种内燃充电系统，内燃充电系统用于对电池500充电；内燃充电系统包括内燃发电机100、整流器200、电源模块300及外接模块400。内燃发电机100用于提供对电池500充电的电量，内燃发电机 100包括启停装置110，启停装置110用于控制内燃发电机100的启动和停止，启停装置110包括启动开关。整流器200用于将内燃发电机100输出的电源转换为第一直流电。电源模块300用于将整流器200输出的第一直流电降压为第二直流电。外接模块400用于与电池500相连；其中，外接模块400与启动开关相连，启动开关用于连通电路使所述电池500能够为所述启停装置110供电；外接模块400与电源模块300相连，电源模块300输出的所述第二直流电经由外接模块400为所述电池500充电。
该内燃充电系统将整流器200、电源模块300及外接模块400模块化安装到内燃发电机100中，同时利用整流器200将内燃发电机100输出的电源整流成第一直流电，有利于稳压。再通过电源模块300将第一直流电降压为第二直流电能够对无人机等设备的电池500进行直接充电。如此，无需携带充电器即可对电池500充电，进而无需搬运充电器，能够降低植保作业的劳动强度；同时内燃发电机100的选择更加灵活，不受充电器供电电压的限制。进一步地，通过外接模块400与启动开关相连，能够利用待充电电池500的剩余电量为内燃发电机100提供启动电能，进而内燃发电机100无需内置移动电源，与传统技术相比，能够降低重量，便于进行搬运。
同时可以理解的，与传统充电方式相比，不用充电器即可为电池500充电，减少中间电压转换过程及电能传递过程中损耗，进而能减少燃油量，降低植保作业成本。
需要说明的是，“启停装置110”具体结构可以根据内燃发电机100的特点进行选择。该启动开关能够实现内燃发电机100与电池500之间的启动供电的通断控制，亦可有多种选择。
如图3及图4所示，可选地，一些实施例中，内燃发电机100还包括内燃机120，启停装置110包括启停控制模块114，用于控制内燃机120启动和停止。如此，利用启停控制模块114发送启动控制程序，使得内燃机120的相关启动元件动作，启动内燃机120，然后内燃机120将化学能转换成机械能，再利用发电装置130将机械能转换成电能，最后利用整流器200输出第一直流电。
如图4所示，具体地，启停装置110包括启动电机140及点火器150、进气单元170门及喷油器160，启停控制模块114与外接模块400连接，启动控制模块分别控制启动电机140、点火器150、进气单元170及喷油器160，用于控制内燃机120启动和停止。如此，启停开关112闭合后，通过启停控制模块114使得启动电机140通电旋转，点火器150通电产生火花、进气单元170打开，为内燃机120的燃烧缸提供 燃烧所需的气体及喷油器160向内燃机120的燃烧缸喷油，实现内燃机120的点火启动。同时该启停控制模块114能够控制其他停止元件停止，如阻气单元180的阀门打开阻止内燃机120进风而关闭内燃机120，或者供油装置停止供油而关闭内燃机120。
一些实施例中，该启动开关为按键开关，撤销按压力后，能够自动复位而断开线路，使得电池500与内燃发电机100上的相关启动元件断开，进而电池500充电时，不会进行供电，有利于保证电池500寿命。
一些实施例中，启动开关为启动电机140的启动开关，启停控制模块114直接利用电池500供电，其他启动元件，通过启停控制模块114控制。如此，启动开关闭合，启动电机140转动，并产生激励信号，使得启停控制模块114根据内燃机120启动特点，控制相关启动元件动作，配合启动电机140实现内燃机120的启动。
启动开关实现上述功能的具体实现方式可以有多种。启停控制模块114属于内燃发电机100的控制装置的一部分，用于控制内燃机120的启动及关闭。该启停控制模块114能够接受控制信息控制内燃机120启动或关闭。该启停控制模块114可以采用多种控制元件实现，如可编程控制器、运动控制卡、控制线路板等。
传统的内燃发电机100充电方式，缺乏必要的交互，用户难以进行充电控制。如图5所示，在上述实施例的基础上，一些实施例中，内燃充电系统还包括第一交互模块600，第一交互模块600与启停控制模块114通信连接，用于通过启停控制模块114控制内燃机120停止或者启动和停止。如此，通过第一交互模块600方便用户进行操作命令的发送，能够实现内燃机120的停止或者启动和停止控制等。而且第一交互模块600与启停控制模块114的配合，使得内燃发电机100的控制操作部分的设计更加灵活，可以将内燃发电机100控制的操作及充电控制的操作都集成到交互模块上来，也可以将启动内燃发电机100的方式保留在传统的内燃发电机100上。
具体地，该第一交互模块600可以有多种选择，包括但不限于机械式控制面板、触摸式控制面板等等。
第一交互模块600需要供电才能进行相应的操作命令的发送，可以内置移动电源，也可以利用电池500或内燃发电机100进行供电，以节省成本。如图5所示，一些实施例中，内燃充电系统还包括逆变器700，逆变器700与整流器200的输出端电连接，用于输出交流电给第一交互模块600，使得第一交互模块600能够通过启停控制模块114控制内燃机120停止。此时，通过逆变器700输出交流电为控制面板供电， 便于在内燃发电机100启动后，通过第一交互模块600进行停止控制的操作，使得充电控制的操作与充电完成后的停止控制的操作集成在一起。
在上述实施例的基础上，一些实施例中，第一交互模块600包括第一指示单元，第一指示单元根据逆变器700输出的交流电变化信息，输出不同的指示状态。进而通过第一指示单元能够获得交流电的相关信息，方便用户查看交流电供给的情况。如，交流电的电压未稳定时，指示状态为红色灯光，以提醒用户暂时不要使用该交流电源，避免用户使用不稳定的交流电，导致用电设备损坏；交流电的电压稳定时，指示状态为绿色灯光，提醒用户可以放心使用交流电源。
或者，一些实施例中，电源模块300还用于供电给第一交互模块600，使得第一交互模块600能够通过启停控制模块114控制内燃机120停止。如此，可以直接利用第二直流电为第一交互模块600供电，便于在内燃发电机100启动后，通过第一交互模块600进行停止控制的操作。
或者，一些实施例中，第一交互模块600与外接模块400电连接，使得电池500能够为第一交互模块600供电。如此，可以直接利用电池500的剩余电量为第一交互模块600供电，进而通过第一交互模块600可以集成一键启停操作，使得内燃充电系统使用更加方便。

所谓“隔离”是指电源的输入回路和输出回路之间没有直接的电气连接，输入和输出之间是绝缘的高阻态，没有电流回路。
需要说明的是，该“隔离电源模块”利用电容电荷充放电过程中的电荷迁移原理，结合控制开关实现降压及稳流输出，可以有多种选择。

在内燃充电系统工作之前，用户可以预先在充电控制模块上配置整流器输出的最大额定电压值(如第一电压阀值)或最大额定电流值(如第一电流阀值)，也可以是配置其他信息，本公开不做限制。同时充电控制模块能够与内燃发电机的控制装置通信，以通过节气系统来控制内燃机的输出功率，实现对内燃发电机的输出电量的功率控制。
如图8所示，在一些实施例中，充电控制模块900首先通过获取第一直流电的电压，然后将获取的第一直流电的电压与第一电压阀值比较。当第一直流电的电压大于第一电压阈值时，充电控制模块900发送控制指令，以使内燃发电机100的输出功率减小，从而对内燃充电系统实现降充电功率，以保证内燃充电系统和待充电电池500 的安全，提高内燃发电机100的使用寿命。

使电源线对应的电源模块的输出电流减小，可以是前述充电控制模块向对应的电源模块发送控制指令，以改变电源模块的开关控制信号的占空比，进而实现减小电源模块的输出电流，也可以是其他方式，本公开不做限制。
在一些实施例中，电压阈值可以基于充电控制模块的温度升高量确定。在极端场景下，供电电源出现跳闸、烧线等问题时，会伴随着充电控制模块温度的变化。所以，电压阈值可以设置为随充电控制模块的温度变化量而升高或者降低一定的量，以实现内燃充电系统的输入功率的限制。
在一些实施例中，电压阈值与充电控制模块的温度升高量正相关。当供电电源出现跳闸、烧线等问题时，充电控制模块的温度往往升高，电源线的阻值变大，因此，电源线对应的电压值也升高。故电压阈值在预先配置时，可以设置为与充电控制模块的温度升高量正相关。

在本公开的一些实施例中，通过控制每个电源模块按照预设的步长逐渐增加输出电流电流值，从而避免充电电流突然变化造成内燃充电系统损坏、整流器跳闸等安 全问题。
通常电源模块都包括如电感之类的感性阻抗。在使用内燃充电系统对待充电电池进行充电的过程中，如果突然通过输入接口向内燃充电系统输入较大的充电电流，电源模块容易产生尖峰电压，可能会造成内燃充电系统上元器件的损坏。为了解决该问题，本公开中，内燃充电系统的充电控制模块可以用于控制电源模块按照预设的步长逐渐增加输出电流的电流值。电源模块和充电控制模块，具有通信子模块，能够实现电源模块与充电控制模块之间的相互通信。电源模块可以是现有技术中的电源模块，也可以是本领域技术人员自己设计的电源模块，本公开对此不作限制。
