Description

一种基于轿厢安全的***A system based on car safety

技术领域Technical field

本发明属于电梯安全技术领域，具体涉及一种基于轿厢安全的***。The invention belongs to the technical field of elevator safety, and particularly relates to a system based on car safety.

背景技术Background technique

电梯***的安全运行保护主要通过检测***、控制***、拖动***和安全保护装置来确保电梯的安全运行实现，检测***是对电梯运行状态进行监测，其控制电梯运行、检测电梯异常运行，并通过直接或间接的方式来使电梯轿厢被紧急制动而处于相对安全状态，防止人员的伤害和设备的损坏。但是，目前的电梯***都是通过间接保护的。The safe operation protection of the elevator system is mainly realized through the detection system, the control system, the driving system and the safety protection device to ensure the safe operation of the elevator. The detection system monitors the elevator operation status, controls the elevator operation, detects the abnormal operation of the elevator, and Directly or indirectly, the elevator car is emergency braked and placed in a relatively safe state to prevent personnel injury and equipment damage. However, the current elevator system is indirectly protected.

从电梯***安全保护的角度来看，目前的安全保护对于不同的故障多采用不同的方案来组合实现，比如：下行超速或坠落大多采用机械限速器、提拉机构和安全钳来实现，对于上行超速或意外移动大多采用电气检测、曳引机制动器来间接作为安全保护或附件制动器来实现，这样的保护存在检测控制、制动部件被分离或是间接来确保安全，导致安全的风险因素增多。From the perspective of elevator system safety protection, current safety protection uses different solutions to achieve different faults. For example: Downstream overspeeding or falling are mostly realized by mechanical speed limiter, lifting mechanism and safety gear. The upward overspeed or accidental movement is mostly realized by electrical detection and traction machine brakes indirectly as safety protection or accessory brakes. Such protection involves detection and control, braking components are separated or indirectly to ensure safety, leading to increased safety risk factors .

从电梯***运行控制角度来看，轿厢是检测控制和安全保护的对象，在轿厢上安装多个检测开关，在每个楼层都安装隔磁光板或在整个运行高度安装检测钢丝绳、磁码带或光等方式来检测轿厢的位置和运行。而采用常规方式存在每个楼层都需要安装相应的检测板，轿厢需要安装位置检测、平层检测、过行程检测开关等；采用外加磁码、光等方式由于受电梯井道环境的影响存在干扰大，环境适用性差的问题。From the perspective of elevator system operation control, the car is the object of detection control and safety protection. A number of detection switches are installed on the car, and a magnetic barrier is installed on each floor or a detection wire rope and magnetic code are installed at the entire operating height. Belt or light methods to detect the position and operation of the car. In the conventional way, each floor needs to install the corresponding detection board. The car needs to be installed with position detection, leveling detection, over-travel detection switches, etc.; additional magnetic code, light, etc. are used because of interference due to the influence of the elevator shaft environment The problem of poor environmental applicability.

从电梯***信号传输的角度来看，电梯控制柜的安装不能随轿厢运行，轿厢位置状态检测、门的状态检测、承载状态检测、人员的对话与监视状态、物联信息收集等都需要通过电缆随动传输，造成传输线缆多而复杂，楼层较高时电压信号衰减大，对检测控制稳定性降低，同时对安全功能提升容量不足，造成信息采集集成传输难。From the perspective of signal transmission of the elevator system, the installation of the elevator control cabinet cannot run with the car. Car position status detection, door status detection, load-bearing status detection, personnel dialogue and monitoring status, and IoT information collection are all required Follow-up transmission through cables results in many and complex transmission cables. When the floor is higher, the voltage signal attenuation is large, which reduces the stability of detection and control, and at the same time, the capacity for safety functions is insufficient, which makes it difficult to collect and integrate information.

从电梯***物联的角度来看，目前由于轿厢的运行性能是通过加装传感器或间接部件测量来采集信号，实现运行、振动、视频采集、通话等功能，比如：通过附加钢丝绳、限速器及张紧装置来测量轿厢超速和坠落。通过门区开关和井道安装隔板来检测轿厢位置和位移。采用的物联技术都是外加传感器，而不是部件本身的物联，外加传感不能实现***件相互物联，非闭环安全控制，没有从电梯的部件是物联的基础上解决问题。From the perspective of the Internet of Things of the elevator system, the current performance of the car is collected by installing sensors or indirect component measurement to collect signals to realize functions such as operation, vibration, video collection, and call, such as: through additional wire ropes, speed limit And tensioning device to measure car overspeed and falling. The position and displacement of the car are detected by the door switch and the hoistway installation partition. The IoT technologies used are all external sensors, not the IoT of the components themselves. External sensors cannot realize the mutual IoT of safety components, non-closed-loop safety control, and the problem is not solved on the basis that the elevator components are IoT.

从电梯***维保的角度来看，目前的电梯***需要定期维保才能确保安全，全国数百万台电梯，定期维护成本较高，维护保养后的电梯安全还是不能从根本上解决安全问题。比如：由于曳引机制动器或其它***件需要15天定期维护，检查曳引机的制动器磨损情况后，在正常情况下是可以确保安全，由于非故障过渡磨损也不能确保安全，目前通过部分视频监控、维护登记等功能建立的维保***不是真正诊断预防性维护，没有实现按需维保，安全物联信息采集不是来自于部件，部件故障不能被诊断，也不能从诊断中精准定位故障，优化调配资源进行预防性精准维保。From the perspective of elevator system maintenance, the current elevator system requires regular maintenance to ensure safety. For millions of elevators across the country, regular maintenance costs are high. After maintenance, the safety of elevators still cannot fundamentally solve the safety problem. For example, since the traction machine brake or other safety components require 15 days of regular maintenance, after checking the traction machine's brake wear, safety can be ensured under normal conditions, but safety cannot be ensured due to non-fault transitional wear. At present, some videos are passed The maintenance system established by monitoring, maintenance registration and other functions is not truly diagnostic and preventive maintenance, and does not realize on-demand maintenance. The security IoT information collection does not come from components, component failures cannot be diagnosed, nor can they be accurately located from the diagnosis. Optimize the deployment of resources for preventive and precise maintenance.

为解决电梯乘用人员的安全，有必要对电梯的安全***进行创新设计。In order to solve the safety of elevator passengers, it is necessary to carry out innovative design of elevator safety system.

具体实施方式detailed description

为了更清楚地说明本发明实施例，下面将对照附图说明本发明的具体实施方式。显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图，并获得其他的实施方式。In order to explain the embodiments of the present invention more clearly, the specific embodiments of the present invention will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative work, other drawings can be obtained based on these drawings and obtained Other embodiments.

实施例一：Example one:

如图1-16所示，本发明实施例的基于轿厢安全的***，包括安装在电梯轿厢0上的检测触发装置A、轿厢控制器K、带提拉力的提拉装置B和紧急保护装置C；电梯轿厢0通过曳引机钢丝绳连接至曳引机及制动器，并延伸至与对重Z连接。当电梯发生上行、下行超速、坠落、上行、下行意外移动等异常运行时，通过检测触发装置A触发提拉装置B，提拉装置B通过夹持电梯导轨产生提拉力，从而将紧急保护装置触发产生制动，实现在轿厢异常运行时的紧急安全保护。As shown in Figures 1-16, the car safety-based system of the embodiment of the present invention includes a detection trigger device A installed on the elevator car 0, a car controller K, a pulling device B with a pulling force, and an emergency Protection device C; the elevator car 0 is connected to the traction machine and the brake through the traction machine wire rope, and extends to be connected to the counterweight Z. When the elevator is running abnormally such as up, down, overspeed, falling, up, down, and unexpected movement, the lifting device B is triggered by detecting the trigger device A, and the lifting device B generates a pulling force by clamping the elevator guide rail to trigger the emergency protection device Braking is generated to realize emergency safety protection when the car is running abnormally.

其中，检测触发装置A，用于通过滚轮与电梯导轨I接触，便于检测触发装置A准确地检测轿厢的运行信息，检测触发装置A还用于在电梯轿厢处于异常运行时触发带提拉力的提拉装置B。具体地，如图4-7所示，检测触发装置A包括检测器1和触发机构2，检测器1用于检测电梯轿厢的运行信息，并在电梯轿厢处于异常运行时驱动触发机构2；本实施例的检测器1为机械式检测器，即机械限速器，故本实施例的检测器检测的电梯轿厢的运行信息为运行速度和位移；而且，轿厢的运行信息通过轿厢与电梯导轨的相对运动获得。特别是通过电梯导轨与轿厢位置移动来检测轿厢位置，省去各楼层的隔离磁光板，光电磁开关等。Among them, the detection trigger device A is used to contact the elevator guide rail I through the roller, so that the detection trigger device A can accurately detect the operation information of the car. The detection trigger device A is also used to trigger the belt pulling force when the elevator car is in abnormal operation.的lifting device B. Specifically, as shown in Figures 4-7, the detection trigger device A includes a detector 1 and a trigger mechanism 2. The detector 1 is used to detect the operation information of the elevator car and drive the trigger mechanism 2 when the elevator car is in abnormal operation. The detector 1 of this embodiment is a mechanical detector, that is, a mechanical speed limiter, so the running information of the elevator car detected by the detector of this embodiment is the running speed and displacement; and, the running information of the car passes through the car The relative movement of the car and the elevator guide rail is obtained. In particular, the position of the car is detected by moving the elevator guide rail and the position of the car, eliminating the need for isolation magneto-optical panels, optical electromagnetic switches, etc. on each floor.

本实施例的电梯轿厢的异常运行为超速或坠落或意外移动等能够通过速度反馈的异常运行，例如，超速的异常运行为电梯轿厢的运行速度超出电梯额定速度的115％、坠落、意外移动的异常运行可以通过运行速度和位移的异常反馈。如图6所示，检测器1位于滚轮11上，滚轮11用于与电梯导轨I接触，即滚轮始终与电梯导轨接触，产生一定的预压力而不脱离导轨，使得检测器检测得到的电梯轿厢的状态更准确。The abnormal operation of the elevator car in this embodiment is an abnormal operation that can be fed through speed feedback, such as overspeed or falling or unexpected movement. For example, the abnormal operation of the overspeed is the operation speed of the elevator car exceeding 115% of the rated speed of the elevator, falling, accident The abnormal movement of the movement can be fed back through abnormal operation speed and displacement. As shown in Figure 6, the detector 1 is located on the roller 11, the roller 11 is used to contact the elevator guide rail I, that is, the roller is always in contact with the elevator guide rail, a certain pre-pressure does not leave the guide rail, so that the detector detects the elevator car The state of the compartment is more accurate.

作为关键所在，本实施例的基于轿厢安全的***将轿厢控制器K从电梯机房转移至轿厢0上，省去了原检测装置所需与电梯使用楼层高度的钢丝绳或同步带等和张紧装置，可大大减少直接和安装维护成本；只需对轿厢控制器K配置一根随行电缆即可(如图1所示的轿厢控制器的上方的随行电缆)，节省了大量的传输电缆，使信号传输更加方便。具体地，轿厢控制器K用于电梯运行的控制、故障的诊断以及紧急保护控制，电梯运行的控制包括曳引机控制、曳引机制动器控制、门状态控制、轿厢位置控制和物联网数据收集处理等，确保人员在门区和运行中的安全。轿厢控制器与检测触发装置A通信连接，用于接收检测触发装置A采集的轿厢的运行信息和故障信息；轿厢控制器还用于采集门区门的状态、轿厢位置、轿厢内部人员信息、制动器的磨损、动作次数等电梯运行的信息；上述采集的信息均是实时信息并记录。轿厢控制器K还能对接收的数据进行分析处理，评估电梯安全风险，实施预防性的维保，并记录相应的维保信息。其中，轿厢内部人员信息可以通过轿厢内的视频监控进行获取，即视频监控摄像机与轿厢控制器通信连接。As the key point, the car safety-based system of this embodiment transfers the car controller K from the elevator machine room to the car 0, eliminating the need for the original detection device and the elevator to use the floor height of the wire rope or timing belt, etc. The tensioning device can greatly reduce the direct and installation and maintenance costs; only need to configure a accompanying cable for the car controller K (the accompanying cable above the car controller as shown in Figure 1), saving a lot of money Transmission cables make signal transmission more convenient. Specifically, the car controller K is used for elevator operation control, fault diagnosis, and emergency protection control. The elevator operation control includes traction machine control, traction machine brake control, door state control, car position control, and Internet of Things Data collection and processing, etc., to ensure the safety of personnel in the gate area and during operation. The car controller communicates with the detection trigger device A, and is used to receive the operation information and fault information of the car collected by the detection trigger device A; the car controller is also used to collect the state of the door area, the position of the car, and the car Internal personnel information, brake wear, number of actions and other elevator operation information; the information collected above is real-time information and recorded. The car controller K can also analyze and process the received data, evaluate elevator safety risks, implement preventive maintenance, and record corresponding maintenance information. Among them, the information of the personnel inside the car can be obtained through the video monitoring in the car, that is, the video monitoring camera is in communication with the car controller.

轿厢控制器通过无线通信技术将其采集的所有信息传输至云端或通过控制器储存，实现电梯运行黑匣子。轿厢控制器和/或云端构成电梯运行的黑匣子，黑匣子还用于通过算法实时监控评估电梯安全状态，并将电梯的运维数据传输到维保端，以便与维保端互动管理，实现诊断式预防性维保。同时通过监测异常故障，诊断电梯的运行，通过物联网实现电梯故障的精准定位或预诊为维保人员由定期维保向诊断预防性精准维保。The car controller uses wireless communication technology to transmit all the information it collects to the cloud or store it through the controller to realize the elevator operation black box. The car controller and/or the cloud constitute the black box of the elevator operation. The black box is also used to monitor and evaluate the safety status of the elevator in real time through algorithms, and transmit the operation and maintenance data of the elevator to the maintenance terminal for interactive management with the maintenance terminal for diagnosis Preventive maintenance. At the same time, by monitoring abnormal faults, diagnosing the operation of elevators, and realizing precise positioning or pre-diagnosis of elevator faults through the Internet of Things, maintenance personnel can change from regular maintenance to diagnosis and preventive precision maintenance.

本实施例的轿厢控制器通过电子、机械传感信息采集，用于检测轿厢位置控制、开关门控制、驱动***控制与制动、紧急安全保护的控制、轿厢承载人员称重、异常紧急保护、故障分析等控制中心，其通过导轨及传感器采集轿厢相关信息并记录，形成数据处理、储存和通信网络连接的中心部件，成为电梯安全运行控制中心。而且，本实施例将曳引机及其制动器作为驱动和驻车功能，极大地简化了轿厢控制器对曳引机及制动器的监测与控制，提高了安全性。The car controller of this embodiment collects electronic and mechanical sensor information to detect car position control, door opening and closing control, drive system control and braking, emergency safety protection control, car carrying personnel weighing, and abnormalities Emergency protection, failure analysis and other control centers, which collect and record car-related information through guide rails and sensors, form the central part of data processing, storage and communication network connection, and become the elevator safe operation control center. Moreover, this embodiment uses the traction machine and its brake as a driving and parking function, which greatly simplifies the monitoring and control of the traction machine and the brake by the car controller, and improves safety.

当检测器1检测到电梯轿厢的状态属于异常运行时，限速器动作联动触发机构2。其中，如图4所示，触发机构2包括驱动件21、转动轴22和联动杆23，驱动件21用于被限速器触发而活动；转动轴22的横截面为方形，相应地，驱动件21具有与转动轴22的横截面结构相配的方孔，当驱动件21安装在转动轴22上，转动轴22能联动于驱动件21；联动杆23具有与转动轴22的横截面结构相配的方孔，当联动杆23安装在转动轴22上，联动杆23能够联动于转动轴22。而且，驱动件21绕转动轴22转动的转动面与联动杆23绕转动轴22转动的转动面相互平行；如图7所示，联动杆23为组件式设计，包括杆体231、套筒232和连杆233，套筒232套设在杆体231之外，且两者通过压簧234相配，杆体231通过基座安装在转动轴22上，使得杆体231联动于转动轴22；连杆233与套筒232之间的连接结构为凹凸配合结构，且连杆233抵靠于杆体231，使得杆体231活动时能联动连杆233活动。When the detector 1 detects that the state of the elevator car belongs to abnormal operation, the overspeed governor action linkage trigger mechanism 2.
