图 4是根据本发明实施例的远程服务终端机的电源管理系统对运行模式的调用 过程流程图。 具体实施方式 需要说明的是, 在不冲突的情况下, 本申请中的实施例及实施例中的特征可以 相互组合。 下面将参考附图并结合实施例来详细说明本发明。 图 1是根据本发明实施例的远程服务终端机的电源管理方法的主要步骤的流程 图。 如图 1所示, 该方法主要包括如下步骤: 步骤 S102:根据安装远程服务终端机的车辆的状态信息、车载电瓶的电压信息、 该车辆的移动速度信息, 以及预设的条件确定远程服务终端机进入的非工作模式。 在本步骤中, 预设的条件包括以下几种情况:
1 )当车辆的状态信息为钥匙开关关闭后的时间超过设定阈值, 则远程服务终端 机进入的非工作模式是休眠模式;
2)当车载电瓶的电压信息是电压值低于设定阈值, 则远程服务终端机进入的非 工作模式是待机模式;
3 )当车辆的移动速度信息是移动速度高于设定阈值, 则远程服务终端机进入的 非工作模式是移动模式。 上述远程服务终端机的三种非工作模式可以根据实际需要灵活搭配, 即可以通 过本机或在线进行参数设置, 从而屏蔽掉部分非工作模式, 因此增添了电源管理的 灵活性。 步骤 S104: 在远程服务终端机进入非工作模式后, 接收对远程服务终端机进行 唤醒的定时唤醒信号。 在本步骤中, 定时唤醒信号是根据预先设置的非工作模式的唤醒时间周期发送 的。不同的非工作模式下对应的唤醒时间周期不同,移动模式的唤醒时间周期最短, 这是因为移动模式下需要尽可能多地采集车辆的运行轨迹数据, 实现对车辆运行状 态的监控。 待机模式的唤醒时间周期最长, 这是因为, 待机模式下车载电瓶储电压 值很低, 为了节省能耗, 保证车辆能够下一次正常启动, 因此设置了较长时间的唤
醒周期。 步骤 S106: 根据定时唤醒信号确定与其相对应的唤醒方式。 在本步骤中,非工作模式下的唤醒方式包括控制远程服务终端机的 GPS模块得 电的 GPS唤醒, 还包括控制远程服务终端机的整机得电的全模块唤醒。 GPS唤醒是 对 GPS模块进行的单独唤醒,全模块唤醒则是对远程服务终端机的整机进行的唤醒, 由于该远程服务终端机处于非工作模式, 不需要与外部 CAN设备进行交互, 因此 进行全模块唤醒时, 该远程服务终端机的 CAN 总线通讯模块不需要唤醒, 仍保持 不被唤醒时的状态。 在本步骤中, 定时唤醒信号的不同决定了唤醒方式的不同, 因此确定远程服务 终端机的唤醒方式是 GPS唤醒还是全模块唤醒,要根据所接收的定时唤醒信号与这 两种唤醒方式之间的对应关系, 譬如, 用" 01"代表第一种定时唤醒信号, "02"代表 第二种定时唤醒信号, 预设' ΌΓ对应的唤醒方式为 GPS唤醒, "02"对应的唤醒方式 为全模块唤醒, 因此当接收的定时唤醒信号为 "01"时, 根据以上对应关系, 则确定 远程服务终端机的唤醒方式为 GPS唤醒, 当接收的定时唤醒信号为 "02"时, 同样根 据上述对应关系, 确定远程服务终端机的唤醒方式为全模块唤醒。 在本步骤中,不同的非工作模式下对应的 GPS唤醒和全模块唤醒的预设唤醒时 间周期不同。 优选地, 休眠模式下, 远程服务终端机每隔 30分钟做一次 GPS唤醒, 每隔 180 分钟做一次全模块唤醒; 移动模式下, 每隔 15分钟做一次 GPS唤醒, 每隔 90分钟 做一次全模块唤醒; 待机模式下, 每隔 120分钟做一次 GPS唤醒, 每隔 700分钟做 一次全模块唤醒。 可以根据实际需要, 预设唤醒时间周期, 唤醒时间周期参数的设 置既可以本机设置, 也可以接收远程服务中心下发的控制指令在线设置。 步骤 S108:根据确定的远程服务终端机的唤醒方式执行与该唤醒方式相应的唤 醒操作。 在本步骤中, 当所确定的远程服务终端机的唤醒方式为 GPS唤醒时, 就会控制
GPS模块得电; 当确定的远程服务终端机的唤醒方式为全模块唤醒时, 则会控制远 程服务终端机的整机得电。 由于处于远程服务终端机非工作模式, 全模块唤醒时, 远程服务终端机的 CAN总线通讯模块不需要唤醒, 仍保持不被唤醒时的状态。
本发明的远程服务终端机的电源管理方法, 在远程服务终端机进入非工作模式 后, 除了上述根据预设唤醒时间周期定时自动唤醒外, 还可以根据所接收到的报警 信息或短信命令进行全模块唤醒, 使远程服务终端机能够全面快速地处理报警信息 或执行短信命令。 本发明的远程服务终端机的电源管理方法, 根据不同的非工作模式设置不同的 唤醒时间周期, 并设置 GPS唤醒和全模块唤醒两种唤醒方式, 实现了在获取充分数 据从而全面掌握安装该终端机的设备的运行状态的同时, 又能避免功耗的浪费, 也 同时实现了的对远程服务终端机的电源平衡管理。 图 2是根据本发明实施例的远程服务终端机的电源管理装置的结构示意图。 如图 2所示, 本发明的远程服务终端机的电源管理装置 200主要包括: 非工作模式确定设备 201, 用于根据安装远程服务终端机的车辆的状态信息、 车载电瓶的电压信息、 该车辆的移动速度信息, 以及预设的条件确定远程服务终端 机进入的非工作模式。 上述预设的条件包括: 当车辆的状态信息为钥匙开关关闭后的时间超过设定阈 值, 非工作模式是休眠模式; 当车载电瓶的电压信息是电压值低于设定阈值, 非工 作模式是待机模式; 当车辆的移动速度信息是移动速度高于设定阈值, 非工作模式 是移动模式。 定时唤醒信号接收设备 202, 用于在远程服务终端机进入非工作模式后, 接收 对远程服务终端机进行唤醒的定时唤醒信号, 定时唤醒信号是根据预先设置的非工 作模式的唤醒时间周期发送的。 唤醒方式确定设备 203, 用于根据定时唤醒信号确定与其相对应的唤醒方式, 唤醒方式包括控制远程服务终端机的 GPS模块得电的 GPS唤醒, 还包括控制远程 服务终端机的整机得电的全模块唤醒。 上述唤醒方式包括控制远程服务终端机的 GPS模块得电的 GPS唤醒, 还包括 控制远程服务终端机的整机得电的全模块唤醒。其中, GPS唤醒是对 GPS模块进行 的单独唤醒, 全模块唤醒则是对远程服务终端机的整机进行的唤醒, 由于该远程服 务终端机处于非工作模式, 不需要与外部 CAN设备进行交互, 因此进行全模块唤 醒时, 该远程服务终端机的 CAN 总线通讯模块不需要唤醒, 仍保持不被唤醒时的 状态。
在三种非工作模式中,待机模式的唤醒时间周期大于休眠模式的唤醒时间周期, 休眠模式的唤醒时间周期大于移动模式的唤醒时间周期。 唤醒操作执行设备 204, 用于根据确定的远程服务终端机的唤醒方式执行与该 唤醒方式相应的唤醒操作。 根据报警信息或短信命令进行全模块唤醒的设备 205, 用于在远程服务终端机 进入非工作模式后, 根据所接收到的报警信息或短信命令进行全模块唤醒。 本发明的远程服务终端机的电源管理装置 200, 根据不同的非工作模式设置不 同的唤醒时间周期, 并设置 GPS唤醒和全模块唤醒两种唤醒方式, 实现了在获取充 分数据并全面掌握安装该终端机的设备的运行状态的同时, 又能避免功耗的浪费, 也同时实现了的对远程服务终端机的电源平衡管理。 图 3是根据本发明实施例的远程服务终端机的电源管理系统的结构示意图。 如图 3所示, 本发明的远程服务终端机的电源管理系统 1主要包括: 主控器 11, 包含本发明的远程服务终端机的电源管理装置 200。 车辆状态检测电路 12, 与主控器 11相连接, 还与安装远程服务终端机的车辆 的钥匙开关 2和发动机 3分别连接, 用于检测该车辆的钥匙开关 2的打开或关闭的 状态信号及发动机 3的转动或熄火的状态信号,并将上述状态信号发送给主控器 11, 主控器 11根据该状态信号控制远程服务终端机进入工作模式或休眠模式。 在本实施例中, 工作模式是为了能自动定时上传基本工作信息包, 实时上传报 警信息,实时上传 GPS定位信息,实时下发监控命令。进入工作模式的判断条件为: 检测到钥匙开关 2打开或发动机 3转速有效。 在本实施例中, 休眠模式是在安装远程服务终端机的车辆熄火停机后使用的模 式, 其目的是能相对多的降低远程服务终端机的功耗, 从而能保证车载电瓶 4在较 长时间停机后还能正常启动, 而不用拆卸充电或找其它的电瓶来接电启动。
GPS模块 13,与主控器 11相连接,用于采集远程服务终端机的 GPS定位信息, 并将该定位信息发送给主控器 11, 主控器 11根据该定位信息计算车辆的位移及移 动速度, 从而判定远程服务终端机是否具备进入移动模式的条件。
在本实施例中, 移动模式是在远程服务终端机检测到车辆处于运输移动途中时 采用的模式, 其目的是能尽可能多的采集到车辆运输轨迹, 而同时又能尽可能少的 消耗车载电瓶 4, 为车辆到达目的地后的启动下车提供保障。 进入移动模式的判断 条件为: 检测到车辆的移动速度超过设定阈值。 电平电压检测电路 14, 与主控器 11相连接, 还与车载电瓶 4相连接, 用于检 测车载电瓶 4的电压信号, 并将上述电压信号发送给主控器 11, 主控器 11根据该 电压信号判断车载电瓶 4是否低于低电压设定阈值, 并低于防馈电电压设定阈值, 从而判定远程服务终端机是否具备进入待机模式的条件。 在本实施例中, 待机模式是在远程服务终端机检测到车载电瓶 4储电量比较低 的时候采用的模式, 进入待机模式需要对车载电瓶 4储电量采用两级检测, 当检测 到车载电瓶 4储电量低于低电压设定阈值, 则会发送低电压报警信息; 当车载电瓶 4 储电量进一步馈电, 使之低于防馈电电压设定阈值, 再进入待机模式。 待机模式 的设置, 其目的是尽可能的保证车辆下一次能顺利启动。 待机模式下, 远程服务终 端机会切断车载电瓶 4而使用自带的内置电池 181。 时钟模块 15, 与主控器 11相连接, 用于发送定时唤醒信号给主控器 11, 主控 器 11根据接收的不同的定时唤醒信号,控制远程服务终端机在不同运行模式下进行 GPS唤醒或全模块唤醒。 在本实施例中, GPS唤醒和全模块唤醒为远程服务终端机的两种定时自动唤醒 方式, 均是在进入休眠模式、 移动模式和待机模式后, 主控器 11根据时钟模块 15 发送的定期自动唤醒信号实现的自动唤醒方式, 这两种唤醒方式的设置, 实现了尽 可能多的采集到车辆运输轨迹, 而同时又能尽可能少的消耗车载电瓶 4, 为车辆到 达目的地后的启动下车及尽可能的保证车辆下一次能顺利启动提供了保障。
GPRS模块 16, 与主控器 11相连接, 用于接收远程服务中心下发的控制指令, 并将该控制指令发送给主控器 11, 譬如根据短信功能, 接收远程服务中心下发的唤 醒命令, 并将该唤醒命令发送给主控器 11, 主控器 11根据该唤醒命令执行短信被 动唤醒。 在本实施例中, 短信被动唤醒是指在休眠模式、 移动模式和待机模式中, 主控 器 11根据接收的短信唤醒命令所进行的全模块唤醒方式。 光电感应模块 17, 与主控器 11相连接, 还与远程服务终端机的机箱壳体 5相 连接, 用于采集机箱壳体 5在打开或闭合状态下的光电感应信号, 并将该光电感应
信号发送给主控器 11, 主控器 11根据该光电感应信号判断机箱壳体 5是否被打开, 若被打开则控制执行报警自动唤醒。 在本实施例中, 报警自动唤醒是指在休眠模式、 移动模式和待机模式中, 主控 器 11根据下述情况所进行的全模块唤醒方式: 1 ) 电平电压检测电路 14检测到车载电瓶 4的电压信号低于设定阈值;
2) GPRS模块 16的天线回路检测功能识别到系统损坏;
3 ) 光电感应模块 17检测到机箱壳体 5被打开。 内置电池 181, 与主控器 11相连接, 用来提供备用电源。 内置电池电压检测电路 182, 分别与内置电池 181和主控器 11相连接, 用于采 集内置电池 181 的电压信号, 并将该电压信号发送给主控器 11, 主控器 11根据内 置电池 181的电压信号判断是否低于设定阈值, 若是, 则判定远程服务终端机处于 死机状态或初始状态。
CAN总线通讯模块 19, 与主控器 11相连接, 用于发送和接收远程服务终端机 与外部 CAN设备间的通讯信息。 图 4是根据本发明实施例的远程服务终端机的电源管理系统对运行模式的调用 过程流程图。 如图 4所示, 远程服务终端机共包括四种运行模式: 工作模式、 休眠模式、 移 动模式和待机模式; 还包括两种定时自动唤醒方式: GPS唤醒和全模块唤醒。 在工作模式下, 远程服务终端机的全部组件均开启, 并正常工作。 在休眠模式、移动模式、待机模式下,只有时钟模块 15、 电平电压检测电路 14、
GPRS模块 16的短信功能处于低功耗的工作状态。这些被保留工作的三部分组件主 要功能是用来保证定时自动唤醒、 报警自动唤醒和短信被动唤醒这三种唤醒途径的 正常工作。 远程服务终端机的四种运行模式可以根据设备的实际需求灵活搭配, 即可以通 过本机或在线进行参数设置, 从而屏蔽掉部分运行模式, 因此增添了电源管理的灵 活性。
如图 4所示, 远程服务终端机的四种运行模式的调用过程具体如下:
1 )初始状态: 刚刚送抵的远程服务终端机都处于初始状态, 即死机状态, 因为 其没有连接任何外部电源, 而且内置电池 181也由于存储和运输时间被消耗殆尽。
2)接车载电瓶 4, 并进行全模块唤醒: 当远程服务终端机初次安装到车辆上时, 接上车载电瓶 4, 并按照设定进行全模块唤醒。
3 ) 工作模式的调用: 远程服务终端机在任何情况下, 如果检测到钥匙开关 2 打开或发动机 3转速有效, 就进入工作模式; 而跳出工作模式的唯一条件就是钥匙 开关 2关闭。
4)休眠模式的调用: 远程服务终端机为了防止在短时间熄火时频繁地跳出工作 模式, 设置了缓冲时间, 也就是在检测到钥匙开关 2关闭后, 首先发送停机信息, 在经历完缓冲延迟后系统进入休眠模式。
5 )待机模式的调用: 远程服务终端机在休眠模式下进行全模块唤醒后, 如果检 测到车载电瓶 4的电压低于设定阈值, 并满足防馈电条件的情况下, 系统发送低电 压信息或发送待机信息后进入待机模式。 6) 移动模式的调用: 远程服务终端机在休眠模式下进行 GPS唤醒后, 如果检 测到车辆的移动速度大于设定阈值, 则发送移动信息后进入移动模式; 或在休眠模 式下进行全模块唤醒后, 检测到车载电瓶 4的电压不低于设定阈值, 如果检测到车 辆的移动速度大于设定阈值, 则发送移动信息后进入移动模式。
7) GPS唤醒和全模块唤醒: 进入休眠模式、 移动模式、 待机模式后, 系统都会 按设定的时间间隔做 GPS唤醒和全模块唤醒, 区别在于: 在休眠模式下全模块唤醒后, 先对车载电瓶 4的电压做判断, 然后再对车辆的 移动速度做判断, 来决定是否满足进入移动模式或发送报警信息的条件; 而在 GPS 唤醒后, 系统将只判断车辆的移动速度是否满足进入移动模式; 在移动模式下全模块唤醒后, 系统只对车载电瓶 4的电压做判断, 决定是否需 要进入待机模式; 在 GPS唤醒后, 只采集 GPS定位信息, 不做任何判断; 在待机模式下全模块唤醒后, 系统只对内置电池 181的电压做判断, 决定是否 有发送死机信息或进入初始状态的必要; 同样的, 在 GPS唤醒后, 只采集 GPS定 位信息, 不做任何判断。
