Description
本发明涉及独立式电梯坠落防护系统及其防护方法。The invention relates to a stand-alone elevator fall protection system and a protection method thereof.
近年来，电梯事故频发，厢式电梯在运行过程中可能会坠落，即使对电梯结构及控制方法进行了大量改进，但仍然没法避免这种坠落。In recent years, elevator accidents have occurred frequently, and the van elevator may fall during operation. Even if the elevator structure and control method are greatly improved, it is still impossible to avoid such a fall.
现有技术中，在电梯坠落时可以弹出安全气囊，但对于安全气囊弹出的时间、速度等无法精准考量，导致其保护措施失效甚至造成二次伤害。In the prior art, the airbag can be ejected when the elevator falls, but the time and speed of the airbag ejection cannot be accurately considered, resulting in failure of the protection measures or even secondary injury.
发明内容Summary of the invention
本发明所要解决的技术问题是提供一种在电梯坠落时能对电梯进行保护、在平时运行时能对电梯进行状态监测的独立式电梯坠落防护系统及其防护方法。The technical problem to be solved by the present invention is to provide an independent elevator fall protection system capable of protecting an elevator when the elevator is falling, and capable of monitoring the state of the elevator during normal operation, and a protection method thereof.
本发明解决上述技术问题的技术方案如下：一种独立式电梯坠落防护系统，包括数据采集模块、处理器、执行机构和安全气囊，The technical solution to solve the above technical problem is as follows: a freestanding elevator fall protection system, comprising a data acquisition module, a processor, an actuator and an airbag,
所述数据采集模块包括速度采集单元、加速度采集单元和对地距离采集单元，上述三个单元依次分别采集电梯当前的运动速度v、加速度a和对地距离h；The data acquisition module comprises a speed acquisition unit, an acceleration acquisition unit and a ground distance collection unit, wherein the three units respectively collect the current movement speed v, the acceleration a and the ground distance h of the elevator respectively;
所述处理器用于接收所述数据采集模块发送的电梯当前的运动速度v、加速度a和对地距离h，将所述运动速度v、加速度a和对地距离h分别与对应的阈值比对，当三者均大于对应的阈值时，处理器向所述执行机构发送动作指令；
The processor is configured to receive a current motion speed v, an acceleration a, and a ground distance h of the elevator sent by the data collection module, and compare the motion speed v, the acceleration a, and the ground distance h to a corresponding threshold, respectively. When all three are greater than a corresponding threshold, the processor sends an action instruction to the executing mechanism;
所述执行机构根据接收的所述动作指令控制安全气囊打开。The actuator controls the airbag to open according to the received motion command.
所述运动速度的阈值为预设的最高运行速度，加速度的阈值为预设的最高加速度，对地距离的阈值为预设的最低对地距离。The threshold of the motion speed is a preset maximum running speed, the threshold of the acceleration is a preset maximum acceleration, and the threshold of the ground distance is a preset minimum ground distance.
本发明的有益效果是：电梯运行时，其运动速度v和加速度a都有一个波动范围，当其运动速度v和加速度a均超过其对应的最高值时，电梯即处于不安全状态，但还不能立即打开安全气囊，因为当电梯的对地高度过低时，打开安全气囊不仅可能起不到减速的作用，还有可能对电梯产生反向作用，这样会给电梯带来更大的损坏，给乘客带来更大的危险。因此同时还要将对地距离h与阈值对比，当对地距离h大于打开气囊的最低高度时，才动作打开安全气囊。The utility model has the beneficial effects that when the elevator is running, the moving speed v and the acceleration a have a fluctuation range, and when the moving speed v and the acceleration a both exceed their corresponding maximum values, the elevator is in an unsafe state, but The airbag cannot be opened immediately, because when the height of the elevator is too low, opening the airbag may not only slow down, but may also have a reverse effect on the elevator, which will cause greater damage to the elevator. Bringing greater danger to passengers. Therefore, at the same time, the ground distance h is compared with the threshold value, and when the ground distance h is greater than the minimum height of the open airbag, the airbag is opened.
在上述技术方案的基础上，本发明还可以做如下改进。Based on the above technical solutions, the present invention can also be improved as follows.
进一步，当三者均大于对应的阈值时，处理器向所述执行机构发送动作指令前还包括根据所述运动速度v和预设的气囊制动加速度a’计算出制动距离L，将对地距离h与所述制动距离L进行比对，当所述对地距离h小于或等于制动距离L时，处理器向所述执行机构发送动作指令。Further, when all three are greater than the corresponding threshold, the processor further includes calculating the braking distance L according to the moving speed v and the preset airbag braking acceleration a' before sending the motion instruction to the executing mechanism, and the pair The ground distance h is compared with the braking distance L. When the ground distance h is less than or equal to the braking distance L, the processor sends an action command to the actuator.
采用上述进一步方案的有益效果是，当电梯的对地距离较高时，若直接打开安全气囊，可以对电梯减速，降低电梯坠落后的危险，但这样电梯最终有可能停在电梯井的中间，停止时距离地面较高，仍然存在危险。且过早打开气囊，可能导致气囊磨损程度较大，因此引入是否打开气囊的进一步判断，即处理器进行比对后，当三者均大于对应的阈值时，计算出制动距离L，当制动距离大于或等于对地距离h时才打开气囊，以解决上述问题。The beneficial effect of adopting the above further solution is that when the distance to the ground of the elevator is relatively high, if the airbag is directly opened, the elevator can be decelerated to reduce the danger of the elevator falling, but the elevator may eventually stop in the middle of the elevator shaft. When it stops, it is higher from the ground and there is still danger. And opening the airbag too early may cause the airbag to wear more, so the further judgment of whether to open the airbag is introduced, that is, after the processor performs the comparison, when the three are greater than the corresponding threshold, the braking distance L is calculated. The airbag is opened when the moving distance is greater than or equal to the ground distance h to solve the above problem.
进一步，还包括数据存储模块，当所述运动速度v和加速度a中有一个或两个数值大于对应的阈值时，处理器向所述存储模块发送当前的运动速度v和加速度a，并将上述信息储存在所述存储模块内。Further, the method further includes a data storage module, when one or two values of the motion speed v and the acceleration a are greater than a corresponding threshold, the processor sends the current motion speed v and the acceleration a to the storage module, and the foregoing Information is stored in the storage module.
采用上述进一步方案的有益效果是，当处理器比对后不满足气囊的打开
条件时，若当前的运动速度v或加速度a中至少一个的数值大于对应的阈值，则说明此时电梯处于非正常的运行状况，通过处理器将此时的运动速度和加速度发送给数据存储模块，可以便于工作人员对电梯运行状态的分析研究。根据电梯的额定参数和气囊的额定参数可以计算出制动加速度a’，所述电梯的额定参数包括额定承载质量和电梯箱体质量，所述气囊的额定参数为气囊充满时间和充满后的摩擦力。The advantage of using the above further solution is that the opening of the airbag is not satisfied when the processor is aligned.
If the value of at least one of the current motion velocity v or the acceleration a is greater than the corresponding threshold value, the elevator is in an abnormal operating state, and the motion speed and acceleration at this time are sent to the data storage module by the processor. It can facilitate the analysis and research of the elevator running state by the staff. The braking acceleration a' can be calculated according to the rated parameters of the elevator and the rated parameters of the airbag. The rated parameters of the elevator include the rated bearing mass and the mass of the elevator car. The rated parameters of the airbag are the airbag filling time and the friction after filling. force.
进一步，所述执行机构包括点火装置，所述执行机构通过点火装置进行点火，从而打开安全气囊。Further, the actuator includes an ignition device that ignites by the ignition device to open the airbag.
进一步，所述安全气囊内有气体发生物质，当点火装置进行点火时，气体发生物质释放出大量气体从而使安全气囊膨胀。Further, the airbag has a gas generating substance therein, and when the ignition device ignites, the gas generating substance releases a large amount of gas to expand the airbag.
进一步，所述气体发生物质为叠氮华纳和/或硝酸铵。Further, the gas generating substance is azidwarner and/or ammonium nitrate.
采用上述进一步方案的有益效果是，通过点火装置触发设置在安全气囊内的气体发生物质，可以瞬间产生大量气体，从而使安全气囊膨胀。The advantage of using the above further solution is that by triggering the gas generating substance disposed in the airbag by the ignition device, a large amount of gas can be instantaneously generated, thereby expanding the airbag.
进一步，还包括为本系统内各用电器供电的电源管理模块，所述电源管理模块包括可充电的备用电源，当电梯断电时，启用所述备用电源为本系统供电。Further, the utility model further includes a power management module for powering each electrical appliance in the system, wherein the power management module includes a rechargeable standby power source, and when the elevator is powered off, the backup power source is enabled to supply power to the system.
进一步，所述速度采集单元为空速管，所述加速度采集单元为多轴电子陀螺仪，所述对地距离采集单元为多普勒雷达。Further, the speed collecting unit is a space velocity tube, the acceleration collecting unit is a multi-axis electronic gyroscope, and the ground distance collecting unit is a Doppler radar.
采用上述进一步方案的有益效果是，在电源管理模块内设置可充电的备用电源，当电梯故障时，可以通过启用备用电源来为本防护系统供电，从而保障乘客和电梯的安全。The advantage of using the above further solution is that a rechargeable backup power source is provided in the power management module. When the elevator fails, the backup power supply can be used to supply power to the protection system, thereby ensuring the safety of passengers and elevators.
