Description

一种减少车辆次声波振动产生的控制系统及方法A control system and method for reducing vehicle infrasonic vibration 技术领域technical field
本发明涉及车辆控制技术领域，尤其涉及一种减少车辆次声波振动产生的控制系统及方法。The invention relates to the technical field of vehicle control, in particular to a control system and method for reducing the generation of vehicle infrasonic vibration.
背景技术Background technique
次声波是频率低于20赫兹的声波。一般来说，人耳所能接受的声波在20-20000赫兹之间，声波频率高于20000赫兹的，称为超声波；低于20赫兹的约则为次声波。次声波与超声波一样都看不见、听不到、摸不着，但次声波频率低、波长长，所以传播距离很远。Infrasound waves are sound waves with a frequency below 20 Hz. Generally speaking, the sound waves that the human ear can accept are between 20-20,000 Hz, and those with a frequency higher than 20,000 Hz are called ultrasonic waves; those with a frequency lower than 20 Hz are called infrasonic waves. Infrasound waves, like ultrasonic waves, are invisible, inaudible, and intangible, but infrasound waves have low frequencies and long wavelengths, so they travel a long distance.
当外来的次声波不管是自然形成的，还是人为制造的，一旦它的振动频率与人体内脏的振动频率相同或接近时，就会引起各种脏器的共振，这一共振便会使人烦躁、耳鸣、头痛、失眠、恶心、视觉模糊、吞咽困难、肝胃功能失调紊乱；严重时，还会使人四肢麻木、胸部有压迫感。When external infrasound waves are naturally formed or man-made, once its vibration frequency is the same or close to the vibration frequency of human internal organs, it will cause resonance of various organs. This resonance will cause irritability, tinnitus, headache, insomnia, nausea, blurred vision, difficulty swallowing, and liver and stomach dysfunction.
目前，汽车的大量使用给人们的出行带来了很大的便利，尤其是乘坐大巴或者公交或者私家车时，能够降低人们出行的疲惫感，但车辆在行驶过程中，难免会有加速或者减速的情况，而根据驾驶员踩油门和刹车的习惯，易引起次声波对人体器官共振，导致乘客在乘坐车辆时，极易产生眩晕感。At present, the extensive use of cars has brought great convenience to people's travel, especially when taking a bus, bus or private car, which can reduce people's sense of fatigue when traveling, but the vehicle will inevitably accelerate or decelerate during driving, and according to the driver's habit of stepping on the accelerator and braking, it is easy to cause infrasound waves to resonate with human organs, causing passengers to easily feel dizzy when riding in a vehicle.

实施例一Embodiment one
如图1所示，本发明一种减少车辆次声波振动产生的控制系统，其包括传感器模块、控制模块、执行机构、报警模块和无线通讯模块。As shown in FIG. 1 , the present invention is a control system for reducing vehicle infrasonic vibration, which includes a sensor module, a control module, an actuator, an alarm module and a wireless communication module.
传感器模块用于在车辆运行时，获取车辆在多个方向上的振动信号。控制模块用于根据所述传感器模块获取的振动信号判断当前车辆的振动频率在次声波频率的预设范围内并且在预设范围内持续预设时间后，生成对应的控制信号。执行机构用于根据控制模块生成的控制信号调节踏板的运行轨迹。报警模块与控制模块连接，其用于根据所述控制信号发出灯光闪烁报警和/或声音报警。无线通讯模块用于将控制模块统计的车辆次声波振动持续时间与车辆工作时间的占比数据发送至服务器中存储。The sensor module is used to acquire vibration signals of the vehicle in multiple directions when the vehicle is running. The control module is used to determine that the vibration frequency of the current vehicle is within the preset range of the infrasonic frequency according to the vibration signal obtained by the sensor module and after staying within the preset range for a preset time, generate a corresponding control signal. The actuator is used to adjust the running track of the pedal according to the control signal generated by the control module. The alarm module is connected with the control module, and it is used for sending out light flashing alarm and/or sound alarm according to the control signal. The wireless communication module is used to send the ratio data of vehicle infrasonic vibration duration and vehicle working time calculated by the control module to the server for storage.
本发明通过传感器实时检测车辆运行过程中的振动情况，并通过控制模块的判断实时调节踏板的运行轨迹，从而降低踏板装置在加速或者减速上的响应速率，减少甚至避免车辆振动产生的次声波。并且通过灯光和声音报警提供驾驶人员次声波的产生，从而使得驾驶员改变踩踏板的力，实 现人和车辆针对削减甚至避免次声波振动产生的双重控制；The present invention detects the vibration situation during the running of the vehicle in real time through the sensor, and adjusts the running track of the pedal in real time through the judgment of the control module, thereby reducing the response rate of the pedal device in acceleration or deceleration, and reducing or even avoiding the infrasonic wave generated by the vehicle vibration. And the generation of infrasonic waves is provided to the driver through light and sound alarms, so that the driver can change the force of stepping on the pedals, and realize the dual control of people and vehicles to reduce or even avoid the generation of infrasonic vibrations;
此外，本发明还通过无线通讯模块将次声波振动产生的数据信息上传至服务器中，后续可对服务器中的数据进行深入研究，可以不断优化车辆结构以避免次声波振动的产生。In addition, the present invention also uploads the data information generated by the infrasonic vibration to the server through the wireless communication module, and then conducts in-depth research on the data in the server, and can continuously optimize the vehicle structure to avoid the generation of infrasonic vibration.
进一步的，如图2和3所示，整个踏板结构包括底座100、旋转板110、第一执行机构、踏板300以及第二执行机构，第一执行机构包括滚轮220和旋转脚210。踏板300的一端与底座100铰接，踏板300靠近底座100的一侧弹性连接有一对旋转脚210，两个旋转脚210之间活动安装有滚轮220，旋转板110与底座100铰接。Further, as shown in FIGS. 2 and 3 , the entire pedal structure includes a base 100 , a rotating plate 110 , a first actuator, a pedal 300 and a second actuator, and the first actuator includes a roller 220 and a rotating foot 210 . One end of the pedal 300 is hinged to the base 100 , a pair of rotating legs 210 are elastically connected to the side of the pedal 300 close to the base 100 , a roller 220 is movably installed between the two rotating legs 210 , and the rotating plate 110 is hinged to the base 100 .
滚轮220内设有用于支撑隔膜222的支撑组件，底座100上设有旋转板110，滚轮220的侧面与旋转板110接触，滚轮220内开设有容纳腔223，当车辆要加速或者减速时，人们需要踩踏对应的踏板300，两个旋转脚210相对踏板300转动，因滚轮220与底座100上的旋转板110接触，使得滚轮220与旋转板110之间具有一定的摩擦力，从而使得滚轮220贴着的旋转板110的表面转动，而车辆在加速或者减速过程中，车辆会产生次声波，在此过程中，控制模块会时刻接收由传感器模块获取的车辆振动信号并判断当车辆振动的频率位于预设范围内且持续了一定的时间时，控制模块会生成控制信号并将该信号传递给支撑组件，支撑组件会向内运动，使得隔膜222也向内凹陷，而此时滚轮220与旋转板110接触部位为隔膜222，如此，便可降低踏板结构的加速或者减速的响应速率，进而削减甚至避免车辆产生的次声波振动，从而避免车辆与人之间发生共振，降低乘客乘车时发生晕车的概率，提高乘客乘车的舒适感。The roller 220 is provided with a support assembly for supporting the diaphragm 222, the base 100 is provided with a rotating plate 110, the side of the roller 220 is in contact with the rotating plate 110, and the roller 220 is provided with a housing cavity 223, when the vehicle is to be accelerated or decelerated, people need to step on the corresponding pedal 300, and the two rotating feet 210 rotate relative to the pedal 300. There is a certain friction between the 10, so that the surface of the rotating plate 110 that the roller 220 is attached to rotates. When the vehicle is accelerating or decelerating, the vehicle will generate infrasonic waves. During this process, the control module will always receive the vehicle vibration signal obtained by the sensor module and judge that when the frequency of the vehicle vibration is within a preset range and lasts for a certain period of time, the control module will generate a control signal and transmit the signal to the support assembly. The support assembly will move inward, so that the diaphragm 222 is also inward. The contact part of 110 is the diaphragm 222, so that the acceleration or deceleration response rate of the pedal structure can be reduced, thereby reducing or even avoiding the infrasonic vibration generated by the vehicle, thereby avoiding resonance between the vehicle and people, reducing the probability of motion sickness when passengers are riding, and improving the comfort of passengers.
当驾驶员要急加速或者急降速时，人们会用力踩踏油门或者刹车踏板300，而此时的滚轮220会迅速越过容纳腔223，使得滚轮220与旋转板110 接触部位为滚轮220的外表面，该踏板结构的加速或者减速的响应速率又会便会正常，从而实现该车辆的急加速或者急降速。When the driver wants to accelerate or decelerate suddenly, people will step on the accelerator or brake pedal 300 hard, and the roller 220 will quickly pass over the receiving chamber 223 at this time, so that the contact part between the roller 220 and the rotating plate 110 is the outer surface of the roller 220, and the acceleration or deceleration response rate of the pedal structure will be normal again, thereby realizing the rapid acceleration or rapid deceleration of the vehicle.
旋转脚210与踏板300之间设有弹簧230，当人们撤去作用在踏板300上的作用力时，弹簧230便会带动旋转脚210复位。A spring 230 is provided between the rotating foot 210 and the pedal 300 , and when people remove the force acting on the pedal 300 , the spring 230 will drive the rotating foot 210 to reset.
隔膜222将容纳腔223封闭，支撑组件位于容纳腔223内，支撑组件包括用于支撑隔膜222的推板221以及用于推动推板221移动的驱动件，其中，隔膜222与推板221连接，人们在正常踩踏该踏板300时，即，车辆产生的次声波不位于预设预设范围时，驱动件将推板221推出，因推板221远离驱动件的一侧面与隔膜222接触，使得推板221将隔膜222撑起来，即，使得隔膜222的形状与滚轮220原有表面的形状相同，如此，使得车辆能够正常行驶。The diaphragm 222 seals the chamber 223, and the support assembly is located in the chamber 223. The support assembly includes a push plate 221 for supporting the diaphragm 222 and a drive for pushing the push plate 221 to move. The diaphragm 222 is connected to the push plate 221. When people step on the pedal 300 normally, that is, when the infrasonic wave generated by the vehicle is not in the preset range, the drive pushes the push plate 221 out, because the push plate 221 is far away from the side of the drive and the diaphragm 22. 2 contact, so that the push plate 221 props up the diaphragm 222, that is, the shape of the diaphragm 222 is the same as that of the original surface of the roller 220, so that the vehicle can run normally.
驱动件包括铁芯224，第一铁芯224的表面缠绕有第一线圈225，推板221朝向第一铁芯224一侧上设置具有磁性的活动杆226，活动杆226活动插设于第一铁芯224内，第一线圈225与控制模块电连接。第一铁芯224内开设有用于活动插设活动杆221的活动孔227，当传感器模块检测到的次声波位于预设范围内时，控制模块会产生控制信号将该信号传递给第一线圈225通电，使得第一铁芯224的周围产生磁场，因活动杆226上具有一定的磁性，使得磁场会对活动杆226产生拉力，从而将活动杆226拉回至活动孔227内，因推板221与活动杆226连接，使得推板226随活动杆226向容纳腔223的内部移动，隔膜222与推板221连接，使得隔膜222也随推板221缩回至容纳腔223内，使得滚轮220与旋转板110的接触位置形成一个缺口，便可降低踏板结构的加速或者减速的响应速率，进而削减车辆产生的次声波振动，提高乘客乘车的舒适感。The driver includes an iron core 224, a first coil 225 is wound on the surface of the first iron core 224, a magnetic movable rod 226 is arranged on the side of the push plate 221 facing the first iron core 224, the movable rod 226 is movably inserted in the first iron core 224, and the first coil 225 is electrically connected to the control module. The first iron core 224 is provided with a movable hole 227 for movable insertion of the movable rod 221. When the infrasonic wave detected by the sensor module is within the preset range, the control module will generate a control signal and pass the signal to the first coil 225 to energize, so that a magnetic field is generated around the first iron core 224. Because the movable rod 226 has a certain magnetic force, the magnetic field will produce a pulling force on the movable rod 226, thereby pulling the movable rod 226 back into the movable hole 227. Because the push plate 221 and the movable rod 22 6 connection, so that the push plate 226 moves to the inside of the accommodation cavity 223 with the movable rod 226, and the diaphragm 222 is connected with the push plate 221, so that the diaphragm 222 also retracts into the accommodation cavity 223 along with the push plate 221, so that a gap is formed at the contact position between the roller 220 and the rotating plate 110, which can reduce the acceleration or deceleration response rate of the pedal structure, thereby reducing the infrasonic vibration generated by the vehicle, and improving the passenger comfort.
当次声波振动消除后，车辆在稳速行驶或者停止状态时，控制模块控 制第一线圈225反向通电，使得第一铁芯224上的产生的新磁场，该新磁场会对活动杆226产生一个向外推送的磁力，如此便可将活动杆226重新推出，使得隔膜223的形状与滚轮220原有表面的形状相同，便完成该支撑组件的复位。When the infrasonic vibration is eliminated and the vehicle is running at a steady speed or at a stop, the control module controls the first coil 225 to be energized in reverse, so that the new magnetic field generated on the first iron core 224 will generate a magnetic force that pushes outward to the movable rod 226, so that the movable rod 226 can be pushed out again, so that the shape of the diaphragm 223 is the same as that of the original surface of the roller 220, and the reset of the support assembly is completed.
本发明通过设置第一执行机构，使得滚轮在滚动时，通过改变滚轮的运行轨迹从而降低踏板结构的加速或者减速的响应速率，削减车辆产生的次声波振动，提高乘客乘车的舒适感。The present invention sets the first actuator so that when the roller is rolling, the acceleration or deceleration response rate of the pedal structure is reduced by changing the track of the roller when the roller is rolling, the infrasonic vibration generated by the vehicle is reduced, and the comfort of passengers is improved.
底座100与旋转板110之间设置有第二执行机构，第二执行机构中设有储液框120，储液框120中储存有纳米磁性液体，纳米磁性液体外围布设有第二线圈(图中未示出)，第二线圈与控制模块电连接。A second actuator is arranged between the base 100 and the rotating plate 110, and a liquid storage frame 120 is arranged in the second actuator, and nano-magnetic liquid is stored in the liquid storage frame 120, and a second coil (not shown in the figure) is arranged on the periphery of the nano-magnetic liquid, and the second coil is electrically connected to the control module.
储液框120是由橡胶材料制作，而橡胶具有一定的弹力，使得储液框120在受外力作用发生变形时，具有迅速复原的能力。The liquid storage frame 120 is made of rubber material, and the rubber has a certain elasticity, so that the liquid storage frame 120 has the ability to recover quickly when it is deformed by an external force.
车辆在加速或者减速过程中，在第一执行机构调节踏板运行轨迹后，传感器模块获取的车辆振动信号仍然处于预设范围内时，控制模块会发送控制信号给第二线圈，第二线圈通电产生磁场，而纳米磁性液体位于储液框的内部并且第二线圈围设在储液框的内部，使得纳米磁性液体受到该磁场的影响，而粘性逐渐降低，直至该粘性达到预设的范围值内，即此时的纳米磁性液体在储液框内的流动性较大，而在此过程中，旋转板110的一端位于储液框120的上方且与储液框120的顶部接触，并且踏板300是通过滚轮220活动安装在旋转板110上，使得储液框变形，旋转板110转动，可进一步降低踏板装置在加速或者减速上的响应速率，进而削减车辆产生的次声波振动。When the vehicle is accelerating or decelerating, after the first actuator adjusts the pedal track, and the vehicle vibration signal acquired by the sensor module is still within the preset range, the control module will send a control signal to the second coil, and the second coil is energized to generate a magnetic field. The nano-magnetic liquid is located inside the liquid storage frame and the second coil is surrounded by the inside of the liquid storage frame, so that the nano-magnetic liquid is affected by the magnetic field, and its viscosity gradually decreases until the viscosity reaches the preset range. One end of 110 is located above the liquid storage frame 120 and is in contact with the top of the liquid storage frame 120, and the pedal 300 is movably installed on the rotating plate 110 through the roller 220, so that the liquid storage frame deforms, and the rotating plate 110 rotates, which can further reduce the response rate of the pedal device on acceleration or deceleration, thereby reducing the infrasonic vibration generated by the vehicle.
此外，在储液框120的正上方设有与车辆连接的第二铁芯320，所述铁芯320的表面缠绕有第三线圈310。当经过一定时间后，该踏板结构的控制 系统控制第三线圈310通电，使得第二铁芯320对旋转板110靠近储液框的一端产生吸力，使得旋转板反向转动，与此同时，因旋转板对储液框不再施加作用力，储液框弹性迅速复原至初始形状，当储液框复原完成后，第二线圈断电，使得纳米磁性液体的粘度增大，此后，第三线圈310断电，使得第二铁芯320不再对旋转板产生吸力，从而恢复调节前的状态。In addition, a second iron core 320 connected to the vehicle is provided directly above the liquid storage frame 120 , and a third coil 310 is wound on the surface of the iron core 320 . After a certain period of time, the control system of the pedal structure controls the third coil 310 to be energized, so that the second iron core 320 generates suction to the end of the rotating plate 110 close to the liquid storage frame, so that the rotating plate rotates in the opposite direction. Suction is generated to restore the pre-adjustment state.
本发明通过第二执行机构中纳米磁性材料的粘性降低，从而进一步降低踏板装置在加速或者减速上的响应速率，进而消除车辆产生的次声波振动，便可避免车辆与人之间发生共振，降低乘客乘车时发生晕车的概率。The present invention further reduces the response rate of the pedal device in acceleration or deceleration by reducing the viscosity of the nano-magnetic material in the second actuator, thereby eliminating the infrasonic vibration generated by the vehicle, thereby avoiding resonance between the vehicle and people, and reducing the probability of motion sickness when passengers ride.
