Problems solved by technology

[0013] The above-mentioned position monitoring method can only make qualitative judgments on the status of rushing to the top, squatting, and leveling, but cannot make quantitative judgments on its accuracy, which is not conducive to accurately controlling the operating status of the elevator
And there are certain limitations to some special trapezoidal installations (such as the installation of a steel belt code disc in a photoelectric switch or an elevator without a magnetic isolation plate, which needs to be redesigned for installation of the magnetic isolation plate)
In addition, components such as photoelectric sensor switches and leveling sensor boards require long-term maintenance. Once damaged, they need to be repaired or replaced immediately, which increases the cost of elevator operation and maintenance.

Embodiment 1

[0064] Please refer to Figure 7 , the present embodiment provides a kind of device for measuring elevator movement, and this device comprises a camera 2 that is installed on the top of elevator car 1, and the benefit that is arranged on the top is easy to install, and camera 2 can also be arranged in other suitable positions certainly, It also includes a target 4 installed in the elevator shaft 3 , the target 4 can be set on the well wall or guide rail of the shaft 3 , and can also be set at other positions that can be photographed by the camera 2 . The camera of the camera 2 faces the position of the target 4, and enables it to fully capture the image of the target 4 during the up and down movement, even if the shooting area of ​​the camera covers the area where the target is located. While the elevator 1 is moving up and down, the camera 2 continuously captures images of the target 4 . The camera 2 also includes a communication module and a communication port, which are us...

Embodiment 2

[0072] Please refer to figure 1 , the present embodiment provides a method for measuring elevator movement, comprising the following steps:

[0073] S101, the camera shoots a target image and sends the target image to the processor, the camera is located on the top of the elevator car, and the target is located in the elevator shaft; and

[0074] S102, the processor acquires the target image, and calculates the motion state of the elevator according to the target image.

[0075] Using the target image collected from the shaft, it is possible to quantitatively measure various motion states of the elevator motion, such as speed, leveling accuracy, top speed and distance, squatting bottom speed and distance, etc. Some of the motion parameters listed above are listed below As an example, the image processing process of S102 will be described in detail.

[0076] The method provided in this embodiment can be applied to the device for measuring the movement of an elevator in any of...

Embodiment 3

[0078] This embodiment is based on S101 and S102 in Embodiment 2, and further describes the measurement method of the elevator moving speed. Please refer to figure 1 together with reference on the basis of figure 2 As shown, step S102 specifically includes:

[0079] S201, acquiring the number of pixels in the target image within a time range,

[0080] S202. Calculate the moving distance of the elevator according to the acquired number of pixels, and calculate the moving speed of the elevator in combination with the time.

[0081] During the operation of the elevator, the target image captured by the camera is composed of pixels. The more the number of pixels, the longer the distance the elevator moves. From this, the distance of the elevator movement can be calculated, and then combined with the time during the movement. Get the elevator movement speed.

[0082] While measuring the speed, you can also measure the direction of movement of the elevator and the location of th...

Abstract

The invention discloses a device for measuring an elevator motion. The device comprises a camera arranged on an elevator car, and a target arranged in an elevator hoistway, wherein the camera is used for shooting a target image and sending the target image to a processor; and the processor calculates a motion state of an elevator according to the target image. In addition, the invention further provides corresponding method and system for measuring the elevator motion. The device is high in measuring accuracy based on a visual system.

Description

technical field [0001] The invention relates to elevator motion monitoring technology, in particular to a device, method and system for measuring elevator motion. Background technique [0002] During the operation of the elevator, it is necessary to monitor the motion state of the elevator. The monitored parameters usually include the speed and acceleration of the elevator car. The existing monitoring methods mainly include two types: [0003] 1. The integrated measurement system with the elevator is adopted. When working, the measurement system is used as a fixed part of the elevator to complete the measurement, and the measurement results are exported to the handheld device or the handheld device connected to the control system through the elevator control system for display; the system also It is divided into the method of converting the speed of the traction machine into the speed of the car and the method of converting the speed of the car according to the speed of the...
