 本发明的最佳实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
参照图1，本申请一实施例中提供了一种基于多物联网模块的电动车防盗方法，所述电动车部署有至少两个物联网模块，所述防盗方法包括：
S1:监测任一所述物联网模块是否被拆除；
S2:若监测到任意一个所述物联网模块被拆除，则判断所述电动车是否处于被盗状态；
S3:若所述电动车处于被盗状态，则唤醒未被拆除的物联网模块，并控制所述未被拆除的物联网模块以指定发送频率发送所述电动车的定位信息到云端服务器。
本实施例中，电动车部署有至少两个物联网模块，优选的，各个物联网模块分散部署于电动车内的不同位置，避免电动车被盗后，被盗贼一次性全部拆除。各个物联网模块分别对应不同的定位信息的初始发送频率，比如物联网模块A的初始发送频率为每天发送一次定位信息，物联网模块B的初始发送频率为每4小时发送一次定位信息，发送频率的具体值可以由用户自定义，也可以为默认出厂设置。在日常使用中，多个物联网模块中只有一个处于唤醒状态，能够正常按照预先设定的频率将电动车的定位信息上传到云端服务器；其余物联网模块处于睡眠状态，避免在不必要的情况下浪费电能。电动车的车载系统通过内部与物联网模块连接的检测电路，实时监测各个物联网模块是否被拆除。如果监测到所有物联网模块中的任意一个被拆除时，则判断电动车是否处于被盗状态。具体地，车载系统可以通过检测电动车是否处于启动状态（比如发动机是否处于工作状态）；或者，唤醒当前所有未被拆除的物联网模块，各个未被拆除的物联网模块被唤醒后按照预设的初始发送频率将电动车的定位信息上传到云端服务器，车载系统通过唤醒的物联网模块在较短的预设时长内（比如5分钟内）所获取的电动车的定位信息，判断电动车在该预设时长是否发生位置改变。如果车载系统检测到电动车未处于启动状态，或者电动车在预设时长内没有发生位置改变，则判定电动车当前不是处于被盗状态，可能是用户需要执行日常维修操作等处理，各个未被拆除的物联网模块保持初始发送频率，从而有效避免误判电动车被盗的情况，减少了不必要的电量消耗。如果车载系统检测到电动车处于启动状态，或者电动车在预设时长内发生位置改变，则判定电动车当前处于被盗状态。此时，车载系统唤醒未被拆除的物联网模块，并发送被盗通知指令到云端服务器，通过云端服务器发送控制指令控制未被拆除的物联网模块按照指定发送频率将定位信息发送到云端服务器。其中，指定发送频率快于初始发送频率，比如初始发送频率为4小时一次，指定发送频率为5分钟一次，从而保证用户能够在被盗的电动车未跑远、并且物联网模块的供电电源的电量未耗尽的情况下，能够通过未被拆除的物联网模块获取电动车的定位信息，并据此进行跟踪寻找，从而实现找回被盗电动车。
本实施例提供的一种基于多物联网模块的电动车防盗装置，电动车部署有至少两个物联网模块，系统实时监测任意一个物联网模块是否被拆除。如果监测到任意一个物联网模块被拆除，则唤醒未被拆除的物联网模块，并判断电动车是否处于被盗状态。如果电动车处于被盗状态，则控制未被拆除的物联网模块以指定发送频率发送电动车的定位信息到云端服务器。本申请中，由于电动车部署有多个物联网模块，在监测到其中任意一个物联网模块被拆除并且电动车处于被盗状态时，及时唤醒剩余未被拆除的物联网模块，并发送电动车的定位信息到云端服务器，以便用户可以根据定位信息及时找回被盗电动车。
进一步的，所述控制所述未被拆除的物联网模块以指定发送频率发送所述电动车的定位信息到云端服务器的步骤，包括：
S301:发送通知指令到所述云端服务器；
S302:接收所述云端服务器反馈的所述指定发送频率，控制所述未被拆除的物联网模块按照所述指定发送频率将所述定位信息发送到所述云端服务器。
本实施例中，电动车内设置有多个物联网模块，在正常工作时（即车载系统未检测到任意一个物联网模块被拆除时），各个物联网模块中仅有一个物联网模块处于唤醒状态，会将电动车的定位信息按照初始发送频率发送到云端服务器；其余物联网模块处于睡眠状态，不会发送电动车的定位信息到云端服务器，从而在电动车正常工作时，能够避免不必要的电量消耗。车载系统在检测到电动车处于被盗状态时，发送通知指令到云端服务器，未被拆除的物联网模块则处于接收指令的状态。云端服务器在接收到车载系统发送的通知指令后，会根据设定下发指定发送频率到车载系统。车载系统在接收到云端服务器反馈的指定发送频率后，控制未被拆除的物联网模块将初始发送频率改变为指定发送频率，将电动车的定位信息按照指定发送频率发送到云端服务器。其中，指定发送频率快于初始发送频率，从而保证用户能够在电动车被盗后未跑远、物联网模块的供电电量未耗尽的情况下，尽量多地利用未被拆除的物联网模块来获取电动车的定位信息，跟踪寻找车辆，找回被盗电动车。
进一步的，所述监测到任意一个所述物联网模块被拆除的步骤之后，包括：
S201:通过所述物联网模块的报警声检测口，判断是否检测到报警声音；
S202:若检测到报警声音，则控制所述未被拆除的物联网模块中处于睡眠状态的物联网模块从睡眠状态进入唤醒状态。
本实施例中，电动车上的各个物联网模块上均设置有报警声检测口，能够主动接收外界的报警声音，并根据报警声音改变工作状态。车载系统在监测到任意一个物联网模块被拆除后，会自动触发电动车上的报警装置，从而使得报警装置发送报警声音。车载系统通过未被拆除的物联网模块的报警声检测口检测到报警声音时，自动控制未被拆除的物联网模块从睡眠状态进入唤醒状态（如果未被拆除的物联网模块中存在处于唤醒状态的模块，则该处于唤醒状态的物联网模块不改变状态，仍处于唤醒状态），从而实现唤醒未被拆除的物联网模块。
进一步的，参见图2、图3，所述物联网模块通过2芯同轴线与所述电动车的主电池连接，所述2芯同轴线包括负载断路检测线；
所述负载断路检测线在所述主电池的一端与上拉电阻R1的一端连接，所述上拉电阻R1的另一端接电源；所述负载断路检测线在所述物联网模块的一端与下拉电阻R2的一端连接，所述下拉电阻R2的另一端接地；
所述上拉电阻R1与第一PMOS管Q1的源极和栅极并联连接，所述第一PMOS管Q1的漏极与报警触发端连接；
所述通过所述物联网模块的报警声检测口，判断是否检测到报警声音的步骤之前，包括：
S2011:当所述第一PMOS管Q1的漏极输出低电平时，触发所述报警装置发出报警声音。
参照图2、图3，本实施例中，单路物联网模块的负载断路检测电路为：电动车的主电池和物联网模块之间采用一根外层带屏蔽接地层的2芯同轴线进行连接，2芯同轴线其中一根芯线为电源线，另外一根芯线为负载断路检测线。负载断路检测线在主电池的一端与上拉电阻R1的一端连接，而上拉电阻R1的另一端则与电源连接。负载断路检测线在物联网模块的一端与下拉电阻R2的一端连接，而下拉电阻R2的另一端接地。上拉电阻R1的两端并联接于第一PMOS管Q1的源极和栅极，第一PMOS管Q1的漏极通过串联一个第二电阻R3接地、同时与报警触发端连接。由于上拉电阻R1和下拉电阻R2的阻值相近（可直接视为两者的阻值相等），正常工作状态下（即2芯同轴线没有被人为断开，物联网模块没有被拆除时），负载断路检测线上的电压约为电源的一半，因此第一PMOS管Q1上的VGS电压值大于第一PMOS的导通阈值电压，第一PMOS管Q1导通，Q1漏极输出高电平，报警触发端不会被触发，电动车报警装置不报警。当2芯同轴线被人为断开时，上拉电阻R1和下拉电阻R2断开，因此上拉电阻R1的两端电压为0，第一PMOS管Q1不导通，其漏极输出低电平，从而触发报警装置，使得报警装置发出报警声音。
进一步的，所述负载断路检测线在所述主电池的一端还与肖特基二极管DA的阳极连接，所述肖特基二极管DA的阴极与所述报警装置的输出唤醒控制端口连接；
所述控制所述未被拆除的物联网模块中处于睡眠状态的物联网模块从睡眠状态进入唤醒状态的步骤，包括：
S3011:当所述报警装置触发时，所述输出唤醒控制端口输出低电平脉冲，所述肖特基二极管DA拉低所述负载断路检测线的电平进而唤醒所述未被拆除的物联网模块中处于睡眠状态的物联网模块进入唤醒状态。
本实施例中，负载断路检测线在主电池的一端与肖特基二极管DA的阳极连接，并且肖特基二极管DA的阴极与报警装置的输出唤醒控制端口连接。其中，在报警装置未触发报警时，输出唤醒控制端口为开路状态或输出高电平。当报警装置被触发时，输出唤醒控制端口输出低电平脉冲，肖特基二极管DA会拉低负载断路检测线的电平，从而唤醒负载断路检测线对应的物联网模块，使得未被拆除的物联网模块从睡眠状态进入唤醒状态。
进一步的，所述下拉电阻R2与NMOS管Q2的源极和栅极并联连接，所述NMOS管Q2的漏极与中断检测口连接；
当所述NMOS管Q2的漏极输出高电平时，触发物联网模块的中断检测，控制被拆除的物联网模块从睡眠状态进入唤醒状态。
参照图3，本实施例中，在物联网模块端，下拉电阻R2的两端并联接于NMOS管Q2的源极和栅极，NMOS管Q2的漏极通过串联第三电阻R4到电源、并与中断检测口连接。正常工作状态下，下拉电阻R2的两端电压高于NMOS管Q2的导通阈值电压，NMOS管Q2导通，其漏极输出低电平，中断检测接口不会触发，物联网模块正常工作和睡眠。当负载断路检测线断路时，下拉电阻R2的两端电压为0，NMOS管Q2不导通，此时NMOS管Q2的漏极输出高电平，从而通过中断检测接口触发物联网模块的终端检测，进而使得当前被拆除的物联网模块被立刻唤醒（被拆除的物联网模块仍保持有短暂的电量），从睡眠状态转换为唤醒状态。
进一步的，所述控制所述未被拆除的物联网模块以指定发送频率发送所述电动车的定位信息到云端服务器的步骤之后，包括：
S4:持续监测所述未被拆除的所述物联网模块的连接数量；
S5:在监测到所述连接数量等于预设值时，切断所述电动车的电源模块与电动机之间的连接。
本实施例中，各个未被拆除的物联网模块在将初始发送频率更改为指定发送频率后，车载系统持续监测各个未被拆除的物联网模块的连接数量（即保持连通状态的数量）。如果各个未被拆除的物联网模块的连接数量在持续减少，当车载系统检测到连接数量减少到预设值，比如连接数量减少到1个时，车载系统则主动切断电动车电源模块与电动机之间的连接，从而使得电动车无法通过电力行走，避免在最后一个物联网模块被拆除后，用户彻底失去电动车的定位信息，导致无法寻回被盗电动车。在车载系统切断电源模块与电动机的连接后，剩余未被拆除的物联网模块仍然保持将电动车的定位信息发送到云端服务器。优选的，车载系统在检测到连接数量减少到预设值，可以自动更改剩余未被拆除的物联网模块的发送频率，使得剩余未被拆除的物联网模块的发送频率更快，保证用户能够得到电动车更详细的定位信息，寻回被盗电动车。
进一步的，所述物联网模块的数量至少为3个，单个物联网模块对应单个第一PMOS管Q1；
各所述第一PMOS管Q1的漏极分别对应串联一组二极管(      D1/D2/D3)和第一电阻(R9/R10/R11)，并全部与分压电阻R12的一端连接；
所述分压电阻R12的两端分别与三极管Q6的基极和发射极连接，所述三极管Q6的集电极与第二PMOS管Q5连接；
所述第二PMOS管Q5的漏极与所述发动机的控制端或电源端连接；
所述切断所述电动车的电源模块与电动机之间的连接的步骤，包括：
S501:当所述第二PMOS管Q5的漏极无电压输出时，控制所述电动机停止工作。
参照图4，本实施例中，电动车上部署的物联网模块的数量至少为3个，单路物联网模块的负载断路检测电路如上所述，每个物联网模块对应单个第一PMOS管Q1。各个第一PMOS管Q1的漏极分别对应串联一组二极管(D1/D2/D3)和第一电阻(R9/R10/R11)，并且各个第一PMOS管Q1均与分压电阻R12的一端连接。分压电阻R12并联在三极管Q6上，两端分别与三极管Q6的基极和发射极连接。三极管Q6的集电极与第二PMOS管Q5连接，而第二PMOS管Q5的漏极则与发动机的控制端或电源端连接。当电动车上有两个或两个以上的物联网模块没有发生断路时，分压电阻R12上的电压分压为第一阈值(比如0.65V）以上，此时三极管Q6导通，第二PMOS管Q5也导通，第二PMOS管Q5的漏极连接电动机的控制端或电源端正常输出电压，从而使得电动机正常工作。当两个或两个以上的物联网模块发生断路时，分压电阻R12上的电压分压为第二阈值（比如0.4V）以下，此时三极管Q6不导通，从而导致与三极管Q6连接的第二PMOS管Q5也不导通，第二PMOS管Q5的漏极无电压输出，从而控制电动机不工作，实现切断电动机与电源模块的连接。同时，单个物联网模块对应的主电池端的一路负载断路检测线上还分别接一个肖特基二极管（D4/D5/D6）的阳极，肖特基二极管（D4/D5/D6）的阴极连在一起接唤醒控制口，唤醒控制口在未报警时为开路状态或输出高电平，当报警装置报警时输出一低电平脉冲唤醒所有未断开的物联网模块。
