Description

技术领域
本发明涉及一种无外部电力登山机的速度调节方法及其装置， 属于有氧 健身器材及其调速方法领域。 背景技术
现有的跑步机包括机械式和电动式两种： 机械跑步机是一种主动式的跑 步机， 无需使用外部电源， 但其速度是随着训练者的运动速度变化而变化的， 无法进行调节， 因此健身训练的效果不明显， 机械跑步机中的登山机由于其 跑带前端翘起， 当人在跑带上跑步时， 在重力加速度的作用下， 跑带速度会 越来越快， 跑带速度无法定速控制， 训练效果很差； 电动跑步机是一种被动 式的跑步机， 训练者需要根据自身体能首先设定跑步速度， 并强行按此速度 进行跑步训练， 因此训练效果好， 但由于电动跑步机是用电机提供动力使跑 步机运转定速， 因此与机械跑步机相比， 又存在着耗能大的缺陷。
发明内容
本发明的目的是提供一种解决现有技术主动式机械跑步机的速度无法进 行调节， 健身训练的效果不明显的缺陷， 提供一种无需外部提供电力， 能耗 小的无外部电力登山机的速度调节方法及其装置。
本发明解决其技术问题所采用的技术方案是：
即一种无外部电力登山机的速度调节方法， 跑带一端翘起与地面形成一 定坡度， 跑带依靠人体重力作为动力转动， 其特征在于安装跑带的前辊筒或 后辊筒处连接有一个发电机， 跑带转动时发电机发电产生电能， 通过消耗上 述电能来控制发电机的转速， 使发电机对与之连接的前辊筒或后辊筒施加阻 力使跑带保持定速转动。
作为本发明的一个优选方案： 发电机产生的电能全部被电子负载消耗。 作为本发明的一个优选方案： 发电机产生的电能一部分储存在蓄电池中， 剩余部分被电子负载消耗。
作为本发明的一个优选方案： 发电机产生的电能全部储存在蓄电池中。 一种无外部电力登山机， 包括机体， 机体下部设有底架， 底架上安装有 跑带， 底架的前端翘起呈倾斜状， 其特征在于安装跑带的前辊筒或后辊筒处 通过传动装置与发电机连接， 发电机通过控制电路与电子负载和 /或蓄电池连 接。
作为本发明的一个优选方案： 发电机通过控制电路与电子负载和蓄电池 连接， 控制电路包括单片机、 第一驱动模块、 第二驱动模块、 充电控制模块 和电压及电流检测模块， 所述单片机的输出分别与第一驱动模块和第二驱动 模块连接， 第一驱动模块的输出与电子负载连接， 第二驱动模块与充电控制 模块连接， 充电控制模块的输出与蓄电池连接， 电压及电流检测模块分别与 电子负载及充电控制模块连接， 发电机分别与电子负载、 充电控制模块及电 压及电流检测模块连接。
作为本发明的一个优选方案： 发电机通过控制电路与电子负载连接， 控 制电路包括单片机、 第一驱动模块和电压及电流检测模块， 所述单片机的输 出与第一驱动模块连接， 第一驱动模块的输出与电子负载连接， 电压及电流 检测模块与电子负载连接， 发电机分别与电子负载、 电压及电流检测模块连 接。
作为本发明的一个优选方案： 发电机通过控制电路与蓄电池连接， 控制 电路包括单片机、 第二驱动模块、 充电控制模块和电压及电流检测模块， 所 述单片机的输出与第二驱动模块连接， 第二驱动模块与充电控制模块连接， 充电控制模块的输出与蓄电池连接， 电压及电流检测模块与充电控制模块连 接， 发电机分别与充电控制模块、 电压及电流检测模块连接。 作为本发明的一个优选方案： 在前辊筒或后辊筒或发电机的转轴上安装 有转速传感器， 单片机与转速传感器连接。 作为本发明的一个优选方案： 所述第一驱动模块由第一 D/A转换模块和第 一驱动电阻组成， 第二驱动模块由第二 D/A转换模块和第二驱动电阻组成。
作为本行业内的公知技术， 第一驱动模块可以仅是第一 D/A转换模块， 第 二驱动模块可以仅是第二 D/A转换模块。
所述转速传感器可以是光电式转速传感器、 电容式转速传感器、 变磁阻式 转速传感器、 单级霍尔开关等任意一种， 但是并不局限于上述的传感器的范围， 也可以采用其他形式的测速装置。
本发明的转速传感器优选但不限于： 单极霍尔开关 AHAH3144E。 单极霍 尔效应开关具有磁性工作阈值（Bop)。如果霍尔单元承受的磁通密度大于工作阈 值， 那么输出晶体管将开启； 当磁通密度降至低于工作阈值（Brp)时， 晶体管 会关闭。 辊筒上装有一永磁铁， 当永磁铁经过霍尔开关时， 霍尔开关输出型号 " 1 "， 通过统计霍尔开关输出信号 " Γ的在单位时间内的次数则可以计算出辊 筒的转速。 传动装置为传动皮带或传动链条或传动齿轮。
当本发明的前辊筒或后辊筒处或发电机的转轴上设有转速传感器时， 控制 电路的单片机通过转速传感器传来的信号判断跑带的转速， 从来控制电能的消 耗来实现控制发电机提供阻力的大小， 保持跑带定速转动。
当本发明的前辊筒或后辊筒处或发电机的转轴上没有转速传感器时， 控制 电路内设有电压及电流检测模块， 发电机主电路中的电压信号通过反馈回路输 入单片机内， 通过芯片内集成的 A/D转换部分处理为数字信号。 此信号与发电 机的转速成正比， 通过计算可以得知发电机的转速， 从而得知辊筒的转速及跑 带运动的速度， 这样根据间接得出的跑带转速来控制电能的消耗实现控制发电 机提供阻力的大小， 保持跑带定速转动。
当本发明的发电机同时与电子负载和蓄电池连接时： 单片机通过检测蓄电 池反馈的电压信号同时通过单片机内集成的 A/D转换模块将其转换成数字信 号。 当控制电路检测到蓄电池的电量不足时则电子负载将不工作或降低其电流 的流量， 将发电机输出的全部或部分电流为蓄电池充电使用， 随着蓄电池的电 量逐渐升高， 控制电路分配给蓄电池充电逐渐减小， 多余的部分由可变的电子 负载消耗掉。 当蓄电池充电时整机负载的组成是： 电子负载 +充电消耗， 当充电 时单片机在控制软件的总体负载下进行分配随着蓄电池充电的进行动态调整电 子负载与充电消耗的比例， 使总体负载保持满足发电机提供阻力的要求。
本发明的工作原理如下：
当人站在具有一定坡度的跑带上时， 因其滑动摩擦系数小， 所以人在自身 重力的作用下会自然向下滑动， 而且此速度在重力加速度的作用下是随着人运 动的速度而逐渐加快的。 为了实现运动速度的可控本发明在前辊筒或后辊筒处 增加了一发电机提供阻力， 使跑带定速转动。
发电机的负载大小可以直接反映在其动力输入的主轴上， 通过调整发电机 的负载大小可以调整与发电机主轴相连的前 /后辊筒受到的阻力大小。 通过调整 前 /后辊筒的阻力的大小可以达到调整跑带的速度的目的。
发电机的负载可以是电子负载 （消耗发电机发出的电能） 也可以是转化为 直流电同时供给训练器的控制部分和蓄电池进行储存。
当控制电路检测到蓄电池的电量不足时将发电机输出的电流全部作为蓄电 池充电使用， 随着蓄电池的电量逐渐升高， 在控制电路的分配下一部分供给蓄 电池充电， 多余的部分由可变的电子负载消耗掉。
本发明由人体运动时经发电机产生的电能不仅可以通过转换电路转化成直 流电由蓄电池进行储存， 还可通过与之相连的电路转变成不同的电压， 不同的 制式给外部的家用电器供电或反馈入电网实现绿色能源的生产。
本发明具有使用灵活方便、 适用范围广、 节能、 健身效果好的优点。 本发 明的跑带在人体的重力作用下下滑， 并以这种下滑动作作为启动能源， 不需要 设置提供动力的驱动电机， 达到了节能效果； 训练者根据自身体能选择合适的 跑步速度， 发电机通过控制消耗产生的电能， 对与之连接的前辊筒或后辊筒施 加合适的阻力， 实现跑带的速度调节， 使训练者强行按设定速度进行跑步训练， 健身效果好； 底架坡度在一定范围内可以变化， 可以适应不同人群的健身需要。 附图说明
