Description

电梯轿厢编码定位***及控制方法Elevator car code positioning system and control method 技术领域Technical field
本发明涉及电梯的领域，特别是涉及一种电梯轿厢编码定位***，尤其适用于井下超深矿井和地面超高建筑内的高速、超高速及大行程的电梯。The invention relates to the field of elevators, in particular to an elevator car code positioning system, and is particularly suitable for high-speed, super-high-speed and large-stroke elevators in underground ultra-deep mines and ground super-high buildings.
背景技术Background technique
随着人们对生活品质追求的不断提高，对于电梯的要求越来越高。在保证电梯安全的前提下，用户追求更加方便快捷的乘坐电梯。设计人员在满足用户需求的前提下，追求更加简单、可靠的电梯***。为保证电梯的安全运行，电梯控制***加入了轿厢定位***、运行速度监测***、平层控制***、限速***、防溜车保护***、防剪切保护***和终端限位保护***等。现有的电梯***中，上述附加的***均为独立***，需要一系列的传感器分布于电梯***的各个部位，每个***需要设置独立的采集模块，采集的信号传输至电梯控制柜的总控制模块，使电梯控制***庞大而繁琐，增大电梯的建设成本，影响电梯的运行可靠性。With the continuous improvement of people's pursuit of quality of life, the requirements for elevators are getting higher and higher. Under the premise of ensuring the safety of the elevator, the user pursues the elevator more conveniently and quickly. The designer pursues a simpler and more reliable elevator system while meeting the needs of the user. In order to ensure the safe operation of the elevator, the elevator control system has added the car positioning system, the running speed monitoring system, the leveling control system, the speed limit system, the anti-sliding protection system, the anti-shear protection system and the terminal limit protection system. In the existing elevator system, the above additional systems are independent systems, and a series of sensors are required to be distributed in various parts of the elevator system. Each system needs to be provided with an independent acquisition module, and the collected signals are transmitted to the overall control of the elevator control cabinet. The module makes the elevator control system large and cumbersome, increases the construction cost of the elevator, and affects the operational reliability of the elevator.
传统的电梯定位***和轿厢运行速度监测大多采用旋转编码器。一般的旋转编码器会安装在曳引机的主轴上，也有一些是安装在限速器的主轴上，从而由主轴的旋转速度来换算出目前电梯的速度，再通过代码的累加来确定电梯的位置。由于这种定位***的值是通过换算而得到的，而且由于齿轮的齿隙以及皮带间的相对滑移的存在，导致这种定位方式相对来说是存在一定的累积误差。Conventional elevator positioning systems and car operating speed monitoring mostly use rotary encoders. The general rotary encoder will be installed on the main shaft of the traction machine, and some will be mounted on the main shaft of the speed limiter, so that the speed of the current elevator can be converted from the rotation speed of the main shaft, and then the accumulation of the code is used to determine the elevator. position. Since the value of such a positioning system is obtained by conversion, and due to the backlash of the gear and the relative slip between the belts, the positioning method has a certain cumulative error.
传统的电梯平层控制大多采用安装在目标层站的光电开关和安装在曳引机主轴的旋转编码器联合控制，此方式只能实现按速度原则减速，当轿厢到达目标层站挡住光电开关，曳引机制动器制动，轿厢速度骤变为零，产生的制动加速度使乘客不适；传统的限速***包括限速器、安全钳、限速绳和涨紧装置，在高层高速电梯***中，限速绳存在晃动，易引起安全钳误动作；传统的防溜车保护***和防剪切保护***大多采用光电开关，原理和平层控制类似，当轿厢停靠与目标层站时，出现曳引绳在曳引轮绳槽内滑移使轿厢运动，且轿厢速度未达到机械动作速度的极端情况时，传统的***无法触发安全钳动作，无法实现防溜车和防剪切保护；终端限位保护***采用限位开关，轿厢已较大速度发生冲顶或墩底时触发限位开关，安全钳立即动作使轿厢骤停，产生较大的制动加速度，对乘客的伤害大；综上所述，现有的上述***均采用独立的传感器，***复杂且控制繁琐，易引起***失效，影响电梯安全性能。The traditional elevator level control is mostly controlled by the photoelectric switch installed at the target landing and the rotary encoder installed on the main shaft of the traction machine. This method can only achieve deceleration according to the speed principle. When the car reaches the target landing, it blocks the photoelectric switch. The traction machine brake brakes, the car speed suddenly becomes zero, and the generated braking acceleration makes the passengers uncomfortable; the traditional speed limit system includes a speed limiter, a safety gear, a speed limit rope and a tensioning device, in the high-rise high-speed elevator In the system, the speed limit rope is shaken, which may cause the safety clamp to malfunction. The traditional anti-rolling protection system and the anti-shear protection system mostly use photoelectric switches. The principle and the level control are similar. When the car stops at the target landing, When the hoisting rope is slid in the rope groove of the traction sheave to move the car, and the speed of the car does not reach the extreme speed of the mechanical movement speed, the conventional system cannot trigger the safety tong action, and the anti-rolling and anti-shearing cannot be realized. Protection; the terminal limit protection system adopts the limit switch. When the car has a large speed, the limit switch is triggered when the top or the bottom of the pier occurs. The safety clamp immediately moves the car to stop. Large braking acceleration, a large injury to passengers; In conclusion, the existing systems are independent of the sensor, the control system complex and cumbersome, can lead to system failure, the elevator safety impact performance.
