技术领域Technical field
本发明属于健身器材技术领域，具体涉及一种跑步机的气囊式减振缓冲机构的控制电路及控制方法。The invention belongs to the technical field of fitness equipment, and specifically relates to a control circuit and a control method of an airbag vibration-absorbing and buffering mechanism of a treadmill.
背景技术Background technique
跑步机是常用的健身器材，广泛用于家庭和商业健身场所。为了降低跑台冲击力，特别是为了能调节跑台的减振缓冲弹性量，越来越多的跑步机采用气囊作为跑台跑步板的弹性功能支撑部件。Treadmills are commonly used fitness equipment and are widely used in home and commercial fitness facilities. In order to reduce the impact force of the treadmill, especially in order to adjust the vibration damping and buffering elasticity of the treadmill, more and more treadmills use air bags as the elastic functional support component of the treadmill running board.
但现有的公开技术都没有考虑在气囊异常破裂时跑步者会由于跑台失去气囊支撑而跌倒，特别是在速度高的情况下更为危险，这种气囊减震缓冲机构存在重大安全隐患。However, the existing public technology does not consider that when the air bag ruptures abnormally, the runner will fall due to the loss of air bag support on the treadmill, which is particularly dangerous at high speeds. This air bag shock-absorbing buffer mechanism has major safety risks.
如中国发明专利申请公布号CN 113018766 A《一种实现跑板软硬度自调节的跑板及跑步机》发明包括框架和跑板本体和气囊，跑板本体安装在框架上，气囊设于框架上，气囊的顶部抵于跑板本体，还包括用于对跑板本体下沉幅度进行监测的下沉监测器和红外光发射管，根据下沉监测器的监测数据，对气囊进行充/放气调节跑板本体的硬度；该专利只考虑根据检测的下沉幅度自动调节气囊气压达到实现跑板软硬度自调节，而红外发射和接收管容易被灰尘遮盖而失效而不能正常控制气囊气压，而且该专利没有考虑到气囊异常破裂引起的安全隐患。For example, the Chinese invention patent application publication number CN 113018766 A "A running board and a treadmill that realizes self-adjusting of the softness and hardness of the running board" The invention includes a frame, a running board body and an air bag. The running board body is installed on the frame, and the air bag is located on the frame. On the top of the running board, the top of the air bag is against the running board body. It also includes a sinking monitor and an infrared light emitting tube for monitoring the sinking amplitude of the running board body. According to the monitoring data of the sinking monitor, the air bag is charged/discharged. The patent only considers the automatic adjustment of the air bag pressure according to the detected subsidence amplitude to achieve self-regulation of the softness and hardness of the running board. However, the infrared transmitting and receiving tubes are easily covered by dust and become ineffective and cannot control the air bag pressure normally. , and the patent does not take into account the safety risks caused by abnormal rupture of the air bag.
再如中国发明专利申请公布号CN113663285A《一种具有减震功能的跑步机及其减震性能自适应调节方法》，跑台底架以及设置于跑台底架上的跑板，跑板和跑台底架之间设置有减震装置，减震装置包括于跑台底架上设置的安装座以及于安装座内设置的气囊，气囊上顶面与跑板下底面抵接或间隙配合，跑台底架上设置有与气囊内部连通的气压传感器和气泵，气囊上设置有控制阀，跑台底架上设置有与气泵、控制阀和气压传感器信号连接的控制系统。主要也是通过气囊气压检测，自动调节气囊气压达到适应体重的减脂功能，该专利也没有考虑到气囊破裂引起的安全隐患。Another example is the Chinese invention patent application publication number CN113663285A "A treadmill with shock-absorbing function and an adaptive adjustment method for its shock-absorbing performance", the treadmill chassis and the running board arranged on the treadmill chassis, the running board and the running board. A shock-absorbing device is provided between the platform base frames. The shock-absorbing device includes a mounting base provided on the treadmill base frame and an airbag provided in the mounting base. The upper top surface of the airbag abuts or has a clearance fit with the lower surface of the running board. The bottom frame of the treadmill is provided with an air pressure sensor and an air pump that are connected to the interior of the air bag. The air bag is provided with a control valve. The bottom frame of the treadmill is provided with a control system connected to the air pump, control valve and air pressure sensor signals. Mainly through air bag air pressure detection, the air bag air pressure is automatically adjusted to achieve the fat loss function that adapts to body weight. This patent also does not take into account the safety hazards caused by air bag rupture.
采用气囊式减振缓冲机构的跑步机确实能通过调节气囊气压达到良好的减振缓冲效果，提高跑步舒适度，减少对膝盖冲击，但是由于气囊在跑步过程的不断冲击，存在气囊气压调节失控，或气囊老化，或尖锐异物碰撞等异常情况引起的气囊破裂，气囊破裂后跑台失去重要的支撑部位，容易引起跑者跌倒，特别在跑步带高速运行中跌倒更为危险。现有技术无法解决该问题。Treadmills that use an air bag shock-absorbing and buffering mechanism can indeed achieve good shock-absorbing and buffering effects by adjusting the air bag air pressure, improve running comfort, and reduce impact on the knees. However, due to the continuous impact of the air bag during running, there is a risk of losing control of the air bag air pressure adjustment. Or the air bag may rupture due to aging of the air bag, or abnormal situations such as collision with sharp foreign objects. After the air bag ruptures, the treadmill loses important supporting parts, which can easily cause runners to fall. Falls are especially dangerous when the running belt is running at high speed. Existing technology cannot solve this problem.
另一方面，随着越来越多的人在跑步机上跑步锻炼，但是很多人由于长期跑步姿态不正确，比如左、右脚落地步或身体左右摆动不平衡，或腾空太高引起反冲力太大等问题，都将引起膝盖损伤等运动伤害。目前跑步姿态监测纠正主要是在鞋子或腰部上挂夹跑姿传感器，但由于外挂设备即不方便使用，而且挂夹的方式不正确也影响监测准确性。另外，虽然有的专业的运动跑台采用多台摄像机多个角度监测跑姿，但成本非常高，无法推广到大众化使用，有鉴于此，遂有了本方案的产生。On the other hand, as more and more people exercise on treadmills, many people have incorrect running postures for a long time, such as the left and right feet landing unbalanced or the body swinging left and right, or the recoil force is too high due to too high aerial. Major and other problems will lead to sports injuries such as knee injuries. At present, running posture monitoring and correction mainly involves hanging a running posture sensor on shoes or waist. However, external devices are inconvenient to use, and the incorrect way of hanging the clip also affects the accuracy of monitoring. In addition, although some professional sports treadmills use multiple cameras to monitor running postures from multiple angles, the cost is very high and cannot be promoted to popular use. In view of this, this solution was developed.

一种跑步机的气囊式减振缓冲机构的控制方法，包括以下步骤：A method for controlling the airbag vibration-absorbing and buffering mechanism of a treadmill, including the following steps:
S1、跑步机正常待机或者正常运作下，控制系统输出预设电平信号，跑步机主系统不触发动作；S1. When the treadmill is in normal standby or operating normally, the control system outputs a preset level signal, and the main system of the treadmill does not trigger action;
S2、通过检测气囊气压传感器的电信号用于判断跑步机是否正常；S2. By detecting the electrical signal of the air bag pressure sensor, it is used to determine whether the treadmill is normal;
S3、当气囊气压传感器感应到低气压的电信号，跑步机停止。S3. When the air bag air pressure sensor senses an electrical signal of low air pressure, the treadmill stops.
进一步，步骤S1具体步骤如下：在跑步机待机或有用户跑步运行情况下，气囊气压随着脚步起落变化，控制系统输出预设电平信号，不会触发跑步机主系统的动作。Further, the specific steps of step S1 are as follows: When the treadmill is on standby or a user is running, the air bag pressure changes with the rise and fall of the footsteps, and the control system outputs a preset level signal, which does not trigger the action of the treadmill main system.
进一步，步骤S2和步骤S3的具体步骤如下：当用户引起落下脚步冲击力太大超过气囊气压上限或气囊破损，对应气囊气压急速降低，左气囊气压传感器或右气囊气压传感器感应到很低气压的电信号，对应的电信号触发对应的气压电信号放大器输出反向电平信号，反向电平信号输入至控制系统，控制系统输出反向电平信号，触发跑步机主系统的关闭跑步机主电机驱动电路电源，停止跑步带运行，确保用户不会被运行的跑步带甩出受伤。Further, the specific steps of steps S2 and S3 are as follows: When the user causes the impact force of the falling step to be too large to exceed the upper limit of the air bag pressure or the air bag is damaged, the corresponding air bag air pressure decreases rapidly, and the left air bag air pressure sensor or the right air bag air pressure sensor senses a very low air pressure. Electrical signal, the corresponding electrical signal triggers the corresponding pneumatic electrical signal amplifier to output a reverse level signal. The reverse level signal is input to the control system. The control system outputs a reverse level signal to trigger the shutdown of the treadmill main system. The motor drives the circuit power supply to stop the running belt, ensuring that the user will not be thrown out by the running belt and injured.
进一步，所述步骤S2中通过单片机内置存储媒介检测跑步者的跑步姿态是否正常，单片机内置存储媒介存储跑步着地方式监测算法软件代码模块，跑步着地方式监测算法软件代码模块根据左脚和右脚着地时采集的过程对应的左气囊气压值和右气囊气压值变化波形判断着地方式，着地方式为前脚掌着地、全脚掌着地和脚跟着地三种。Further, in step S2, the built-in storage medium of the microcontroller is used to detect whether the runner's running posture is normal. The built-in storage medium of the microcontroller stores the running landing pattern monitoring algorithm software code module. The running landing pattern monitoring algorithm software code module determines whether the running landing pattern monitoring algorithm software code module is based on the landing of the left foot and the right foot. The corresponding waveforms of left airbag air pressure value and right airbag air pressure value collected during the process are used to determine the landing mode. The landing modes are forefoot landing, full foot landing and heel landing.
1.与现有技术相比，本发明具有以下有益效果：本发明通过通过控制系统的设计持续监测气囊气压，一方面通过将气囊气压控制在安全阀值范围，另一方面在气囊异常破裂时通过左气囊气压传感器、右气囊气压传感器、左气压电信号放大器和右气压电信号放大器的配合，相应破损部位的气囊气压传感器和电信号放大器发生电信号给控制系统，使得控制系统发生电信号给跑步机主系统，跑步机主系统紧急停止跑步机运行，确保跑步者不会由于跑台失去气囊支撑而跌倒，以杜绝安全隐患。1.

右脚触地冲力比例:F_Balance_Ratio_right＝F_right_touch/(F_left_touch+F_right_touch)。Right foot touchdown momentum ratio: F_Balance_Ratio_right=F_right_touch/(F_left_touch+F_right_touch).
跑步步数步频算法模块其算法为：步数计数器Step_counter，秒累加器Second_Timer。The algorithm of the running step count and cadence algorithm module is: step counter Step_counter, second accumulator Second_Timer.
跑步机待机时，设置步数计数器Step_counter＝0。When the treadmill is on standby, set the step counter Step_counter=0.
跑步机运行后：秒累加器Second_Timer开始计时：After the treadmill runs: the second accumulator Second_Timer starts timing:
当右脚状态标志right_foot_status从1至0时，Step_counter+1。When the right foot status flag right_foot_status goes from 1 to 0, Step_counter+1.
当左脚状态标志left_foot_status从1至0时，Step_counter+1。When the left foot status flag left_foot_status goes from 1 to 0, Step_counter+1.
即步数为：Step_counter。That is, the number of steps is: Step_counter.
平均步频为：Cadence＝Step_counter/(Second_Timer/60)。The average cadence is: Cadence=Step_counter/(Second_Timer/60).
本方案采用了上述结构又提供了一种跑步机的气囊式减振缓冲机构的控制方法，包括以下步骤：This solution adopts the above structure and provides a control method for the airbag vibration-absorbing and buffering mechanism of the treadmill, including the following steps:
S1、跑步机正常待机或者正常运作下，控制系统6输出预设电平信号，跑步机主系统1不触发动作；步骤S1具体步骤如下：在跑步机待机或有用户跑步运行情况下，气囊气压随着脚步起落变化，控制系统6输出预设电平信号，不会触发跑步机主系统1的动作。S1. When the treadmill is in normal standby or operating normally, the control system 6 outputs a preset level signal, and the treadmill main system 1 does not trigger an action; the specific steps of step S1 are as follows: When the treadmill is in standby or a user is running, the air bag pressure As the steps rise and fall, the control system 6 outputs a preset level signal and does not trigger the action of the treadmill main system 1.
S2、通过检测气囊气压传感器的电信号用于判断跑步机是否正常；S2. By detecting the electrical signal of the air bag pressure sensor, it is used to determine whether the treadmill is normal;
S3、当气囊气压传感器感应到低气压的电信号，跑步机停止。S3. When the air bag air pressure sensor senses an electrical signal of low air pressure, the treadmill stops.
步骤S2和步骤S3的具体步骤如下：当用户引起落下脚步冲击力太大超过气囊气压上限或气囊破损，对应气囊气压急速降低，左气囊气压传感器2或右气囊气压传感器3感应到很低气压的电信号，对应的电信号触发对应的气压电信号放大器输出反向电平信号，反向电平信号输入至控制系统6，控制系统6输出反向电平信号，触发跑步机主系统1的关闭跑步机主电机驱动电路电源，停止跑步带运行，确保用户不会被运行的跑步带甩出受伤。The specific steps of steps S2 and S3 are as follows: When the impact force of the user's falling step is too large to exceed the upper limit of the air bag pressure or the air bag is damaged, the corresponding air bag air pressure decreases rapidly, and the left air bag air pressure sensor 2 or the right air bag air pressure sensor 3 senses a very low air pressure. Electrical signal, the corresponding electrical signal triggers the corresponding pneumatic electrical signal amplifier to output a reverse level signal, the reverse level signal is input to the control system 6, the control system 6 outputs a reverse level signal, triggering the shutdown of the treadmill main system 1 The main motor of the treadmill drives the circuit power supply to stop the running belt to ensure that the user will not be thrown out by the running running belt and be injured.
其中步骤S2中通过单片机7内置存储媒介检测跑步机是否正常，单片机7内置存储媒介存储跑步着地方式监测算法软件代码模块，跑步着地方式监测算法软件代码模块根据左脚和右脚着地时采集的过程对应的左气囊气压值和右气囊气压值变化波形判断着地方式，着地方式为前脚掌着地、全脚掌着地和脚跟着地三种，如图2-4所示。In step S2, the built-in storage medium of the single-chip computer 7 is used to detect whether the treadmill is normal. The built-in storage medium of the single-chip computer 7 stores the running landing pattern monitoring algorithm software code module. The running landing pattern monitoring algorithm software code module is based on the process of collecting when the left and right feet touch the ground. The corresponding change waveforms of the left airbag air pressure value and the right airbag air pressure value are used to determine the landing mode. The landing modes are forefoot landing, full foot landing and heel landing, as shown in Figure 2-4.
