请参见图1，本申请提供一种叉车电池状态监测方法，包括：
S100，确定是否存在电池信息。
需要说明的是，叉车电池一般包括锂电池和铅酸电池。当锂电池与所述单片机通信连接时，所述单片机可以通过CAN(Controller Area Network，控制器局域网络)获取锂电池的电池信息。所述电池信息至少包括锂电池的电池容量信息和电量信息。
S200，若存在电池信息，则确定叉车电池的类型为锂电池。
若所述单片机可以检测到所述电池信息，则可以确定此时所述叉车电池的类型为锂电池。
S300，若不存在电池信息，则确定模拟量输入口是否存在电压信号。
若所述单片机检测不到所述电池信息，则需要确定所述单片机的模拟输入口是否存在电压信息。
S400，若存在所述电压信号，则确定所述叉车电池类型为铅酸电池。
若存在所述电压信息，则可以确定此时为铅酸电池与单片机连接。因此，可以确认所述叉车电池的类型为铅酸电池。若既不存在所述电池信息，又不存在所述电压信息，则可以确定此时没有电池接入，则单片机无法判断所述叉车电池的类型为锂电池还是铅酸电池。
S500，根据所述叉车电池的类型，监测所述叉车电池的状态。
所述监测所述叉车电池的状态，主要指的是所述叉车电池的电量信息。可以理解的是，若所述叉车电池的类型为锂电池，则可以直接获取所述叉车电池的电量信息。若所述叉车电池为铅酸电池，则需要在所述单片机和所述模拟量输入口之间设置电池电压转换电路，所述电池电压转换电路用于降压，以使从所述铅酸电池输出的电压被转换为所述单片机可以进行检测的电压范围。例如，所述单片机可以进行检测的电压范围在0V至5V，而所述铅酸电池为额定电压为24V的电池。此时，所述电池电压转换电路需要将从所述铅酸电池输出的电压转换为0V至5V的范围。所述电池电压转换电路需要根据铅酸电池的额定电压的最大值和所述单片机的电压检测范围选择。例如，工作人员在选择铅酸电池作为叉车电池时只选择了额定电压为24V和额定电压为48V的铅酸电池，此时需要考虑的所述铅酸电池的额定电压的最大值为48V。
本实施例提供一种叉车电池状态监测方法，包括检测叉车电池类型和获取叉车电池状态信息。可以理解的是，叉车上的单片机可以通过是否检测到所述电池信息，确定叉车电池是否为锂电池。若检测到所述电池信息，则确定所述叉车电池的类型为锂电池。若没有检测到所述电池信息，则检测所述模拟量输入口是否存在电压信息。若是有所述电压信号，则证明所述叉车电池的类型为铅酸电池。若所述叉车电池的类型为锂电池，则获取所述锂电池的状态信息。若所述叉车电池的类型为铅酸电池，则获取所述铅酸电池的状态信息。本申请提供的叉车电池监测方法无需工作人员人工进行叉车电池类型的区分，可以在获知叉车电池类型之后及时获取叉车电池的状况，解决了传统方案中对叉车电池状况进行监测的方法存在无法及时获知电池状况的问题。
请参阅图2，在本申请的一个实施例中，S400包括：
S410，若所述叉车电池的类型为铅酸电池，则获取所述模拟量输入口的电压值；
S420，若所述电压值大于预设电压值，则确定所述叉车电池为第一类铅酸电池；
S430，若所述电压值小于所述预设电压值，则确定所述叉车电池为第二类铅酸电池。
需要说明的是，若所述单片机的电压检测范围可以覆盖所述铅酸电池的额定电压，例如，所述单片机的电压检测范围为0V至30V，此时铅酸电池的额定电压为24V，则可以直接获取所述模拟量输入口的电压值。
若所述单片机的电压检测范围不能覆盖所述铅酸电池的额定电压，例如，所述单片机的电压检测范围为0V至12V，此时铅酸电池的额定电压为24V，则此时所述单片机不能直接获取所述模拟量输入口的电压值，而需要获取电池电压转换电路的转换比例，基于所述转换比例和所述单片机采集到的电压值，可以计算得到所述模拟量输入口的电压值。例如，所述电池电压转换电路的转换比例为0.5，所述单片机采集到的电压值为8V，则此时可以计算得到所述模拟量输入口的电压值为16V。
可以理解的是，在本实施例中，所述第一类铅酸电池指的是额定电压为48V的电池，所 述第二类铅酸电池指的是额定电压为24V的电池。所述预设电压值不一定为24V，一般是根据铅酸电池的实际状况决定。例如，所述第二类铅酸电池虽然为24V电池，但是输入至所述模拟量输入口的电压值可能会达到28V，但是所述第一类铅酸电池输入至所述模拟量输入口的电压值不会到28V。此时，便于区分所述第一类铅酸电池和所述第二类铅酸电池，可以将所述预设电压值设定为28V。即，所述预设电压值必须为所述第二类铅酸电池输入至所述模拟量输入口的电压最大值，但此时所述第一类铅酸电池输入至所述模拟量输入口的电压不会为所述第二类铅酸电池输入至所述模拟量输入口的电压最大值。
本实施例提供的方法可以在判断所述叉车电池类型为铅酸电池之后，进一步判断所述叉车电池为哪一种铅酸电池，使工作人员更详细的了解所述叉车电池的类型。可以理解的是，所述铅酸电池不一定只包括所述第一类铅酸电池和所述第二类铅酸电池，所述铅酸电池可能会根据额定电压的不同分为很多类铅酸电池。但是在区分所述铅酸电池的类型的时候都是需要基于所述模拟量输入口的电压值进行区分。
请参见图3，在本申请的一个实施例中，S500包括：
S510，若所述叉车电池的类型为锂电池，则基于控制器局域网络监测所述叉车电池的电量；
S520，若所述叉车电池的类型为铅酸电池，则根据所述电压值确定所述叉车电池的电量，并监测所述叉车电池的电量。
可以理解的是，若所述叉车电池的类型为锂电池，则单片机可以直接通过CAN(Controller Area Network，控制器局域网络)获取锂电池的电量，并对所述锂电池的电量，即所述叉车电池的电量进行监测。若所述叉车电池的类型为铅酸电池，则单片机需要根据所述模拟量接入口的电压值确定所述叉车电池的电量。需要说明的是，若所述单片机的电压检测范围不能覆盖所述铅酸电池的额定电压，例如，所述单片机的电压检测范围为0V至12V，此时铅酸电池的额定电压为24V，则此时所述单片机不能直接获取所述模拟量输入口的电压值，而需要获取电池电压转换电路的转换比例，基于所述转换比例和所述单片机采集到的电压值，可以计算得到所述模拟量输入口的电压值。例如，所述电池电压转换电路的转换比例为0.5，所述单片机采集到的电压值为8V，则此时可以计算得到所述模拟量输入口的电压值为16V。根据所述模拟量输入口的电压值和所述铅酸电池的额定电压值，就可以推算出铅酸电池的电量，即所述叉车电池的类型为铅酸电池时，所述叉车电池的电量。
在本申请的一个实施例中，所述叉车电池状态监测方法还包括：
S530，若所述叉车电池的电量小于等于预设电量，则生成报警命令。
所述预设电量可以为所述叉车电池满电量的百分之十或者百分之二十，工作人员可以根据实际需要设置所述预设电量的值。若所述叉车电池的电量小于等于所述预设电量，则说明所述叉车电池需要进行充电，此时就需要生成所述报警命令。
在本申请的一个实施例中，S530包括：
S531，若所述叉车电池的电量小于等于第一预设电量，则生成一级报警命令；
S532，若所述叉车电池的电量小于等于第二预设电量，则生成二级报警命令。
所述第一预设电量和所述第二预设电量可以根据实际需要选择，本申请不做限定。需要说明的是，所述第一预设电量可以大于所述第二预设电量，所述第一预设电量也可以小于所述第二预设电量，具体可以根据实际需要选择，本申请不做限定。在一个实施例中，所述第一预设电量可以为所述叉车电池总电量的百分之二十，所述第二预设电量可以为所述叉车电池总电量的百分之十。
在本申请的一个实施例中，所述叉车电池状态监测方法还包括：
若所述叉车电池的电量小于等于所述第二预设电量，则控制切段所述叉车电池的电连接关系。
在一个实施例中，所述第二预设电量小于所述第一预设电量。若所述叉车电池的电量小于等于所述第二预设电量，则证明再使用所述叉车电池会对所述叉车电池造成比较严重的损坏。此时，需要所述单片机控制切断所述叉车电池的电连接关系，以保护所述叉车电池不被损坏。
在本申请的一个实施例中，S200之后，所述方法还包括：
S210，获取锂电池信息库；
S220，将所述电池信息和所述锂电池信息库进行信息匹配，并根据匹配结果确定锂电池类型。
可以理解的是，所述锂电池信息库包括不同类型的锂电池，所述不同类型的锂电池有不同的电池容量。所述锂电池信息库可以由工作人员提前录入至所述单片机中。所述单片机在获取了所述电池信息之后，可以将所述电池信息与所述锂电池信息库中的信息进行匹配，寻找与所述电池信息相同的锂电池类型，由此，就可以确定所述电池信息对应的锂电池类型。
