依本发明的另一个方面,本发明进一步提供了所述割草机械的电控方法,其中所述电控方法包括步骤:
(a)获取所述割草机械的各个机构的闭合和/或断开状态;和
(b)基于一控制逻辑,根据所述割草机械的各个机构的闭合和/或断开状态控制所述割草机械的工作状态。
例如,在本发明的所述割草机械中,所述供电装置门锁开关闭合和/或断开状 态、所述座椅闭合和/或断开状态、所述驻车开关闭合和/或断开状态、所述刹车开关闭合和/或断开状态、所述割草开关闭合和/或断开状态均能够被获取,以在后续,基于所述控制逻辑,可以根据所述供电装置门锁开关闭合和/或断开状态、所述座椅闭合和/或断开状态、所述驻车开关闭合和/或断开状态、所述刹车开关闭合和/或断开状态以及所述割草开关闭合和/或断开状态控制所述割草机械的工作状态。例如,所述割草机械的工作状态能够在停机状态、待机状态、行走状态、割草状态之间被切换,以保证所述割草机械的安全性能和割草效率。
值得一提的是,在本发明的所述割草机械中,获取所述供电装置门锁开关闭合和/或断开状态、所述座椅闭合和/或断开状态、所述驻车开关闭合和/或断开状态、所述刹车开关闭合和/或断开状态以及所述割草开关闭合和/或断开状态的方式不受限制,例如分别通过在上述各个机构设置传感器的方式获取各个机械的开关和/或闭合状态。
所述控制逻辑包括一开机逻辑,所述开机逻辑包括在所述供电装置门锁开关闭合、所述座椅开关闭合、所述驻车开关闭合、所述刹车开关闭合以及所述割草开关断开时控制所述割草机械处于待机状态和能够被切换至行走状态。换言之,若所述供电装置门锁开关断开、或者所述座椅开关断开、或者所述驻车开关断开、或者所述刹车开关断开、或者所述割草开关闭合,则所述割草机械处于停机状态。
进一步地,在所述供电装置121为所述割草机械供电时,若所述驻车开关断开或者所述刹车开关断开或者所述割刀开关闭合,则所述割草机械报警。也就是说,在所述供电装置121为所述割草机械供电时,若所述驻车开关断开或者所述刹车开关断开或者所述割刀开关闭合,则所述割草机械被认定为故障状态,此时,所述割草机械会产生报警,以提醒驾驶员。值得一提的是,所述割草机械产生报警的方式可以是但不限于显示屏幕显示报警或者声音报警或者显示屏幕显示报警和声音报警相互配合等。
进一步地,在所述供电装置121为所述割草机械供电后,若所述座椅开关断开,则所述割草机械被切换至停机状态,如此可以保证驾驶员的安全。例如,所述座椅开关的闭合和断开状态可以通过一个压力传感器被获取,当驾驶员的重力施加于所述座椅14时,所述座椅开关处于闭合状态,当驾驶员的重力未施加于所述座椅14时,所述座椅开关处于断开状态,从而在所述供电装置121为所述割草机械供电后,若所述压力传感器检测到驾驶员的重力未施加于所述座椅14 时,例如驾驶员在所述割草机械上站立,则所述割草机械认定为所述座椅开关断开,此时,所述割草机械被切换至停机状态,以保证驾驶员的安全。
为了进一步保证驾驶员的安全,在所述割草机械被切换至停机状态后,若所述压力传感器再次检测到驾驶员的重力施加于所述座椅14而使所述座椅开关闭合时,所述割草机械仍然被保持在停机状态,此时,所述割草机械允许驾驶员复位所述割草机械以切换所述割草机械的工作状态至待机状态。

进一步地,所述行走逻辑包括所述割草机械在所述割刀开关断开时的前进速度分为三档,和所述割草机械在所述割刀开关闭合时的前进速度分为两档。例如,在所述割刀开关断开时,所述割草机械包括一个前进高速挡,其速度为20km/h,一个前进中速挡,其速度为10km/h,一个前进低速挡,其速度为5km/h,其中当所述割草机械的所述供电装置121处于低电量以及BMS报警时,所述割草机械仅能够被允许在前进低速度行走。相应地,所述行走逻辑包括所述割草机械在所述割刀开关断开时的后退速度分为三档,和所述割草机械在所述割刀开关闭合时的后退速度分为两档。
优选地,在所述割草机械处于行走状态时,若所述座椅开关断开时间少于一第一预设时间,例如2秒,则所述割草机械被维持在行走状态,若所述座椅开关断开时间超过所述第一预设时间,则所述割草机械被切换至停机状态,如此可以在保证驾驶员安全的同时,提高所述割草机械的作业效率。进一步地,在所述割草机械处于行走状态时,若所述座椅开关断开时间超过所述第一预设时间而使所述割草机械被切换至停机状态,所述割草机械允许驾驶员复位所述割草机械以切换所述割草机械的工作状态至待机状态。
优选地,所述割草机械具有两个刹车开关,以分别控制所述割草机械的两侧的刹车机构,其中在两个刹车开关均断开时,刹车机构的电磁刹才能够被打开,在两个刹车开关中的至少一个刹车开关闭合时,刹车机构的电磁刹均吸合,以完 成刹车而使所述割草机械处于停机状态。
优选地,在所述供电装置121有故障信号时,例如所述可充电电芯1212有停止故障信号或者所述电芯管理器1213有充电禁止行走信号时,所述割草机械处于停机状态。
所述控制逻辑包括一割草逻辑,所述割草逻辑包括在所述座椅开关闭合时,所述割草机械的所述割草机构20处于待机状态和能够被切换至至割草状态。所述割草机械20的转速被控制为两档,其中高速挡转速为3200RPM,低速挡转速为2800RPM,以供驾驶员在割草的过程中进行选择。在本发明的所述割草机械中,所述割草机构20的控制器互锁由座椅开关控制,只有在所述座椅开关闭合时,所述割草机构20的控制器才能够处于ON状态,以允许所述割草机构20处于待机状态和能够被切换至至割草状态,相应地,若所述座椅开关断开,则所述割草机构20的控制器处于OFF状态。
进一步地,所述割草逻辑包括在所述割草机械的所述割草机构20处于割草状态时,若所述座椅开关断开,则所述割草机械的所述割草机构20被切换至待机状态,在所述座椅开关闭合时,所述割草机械的所述割草机构20被维持在待机状态,只有在所述割草机械的所述割刀开关闭合时,所述割草机械的所述割草机构20被切换至割草状态,以保证所述割草机械的安全性。优选地,在所述割草机械的所述割草机构20处于割草状态时,若所述座椅开关断开和闭合的间隔时间少于一第二预设时间,例如2秒,则所述割草机械的所述割草机构20被维持在割草状态,以在保证驾驶员的安全的同时,提高所述割草机械的作业效率。
