Embodiment 1

[0052] This embodiment discloses a method for monitoring the movement state of a switch cabinet chassis handcart, the steps are as follows:

[0053] The image acquisition equipment is arranged, and the images of the switchgear chassis handcart 5 provided with two marking points are collected by the image acquisition equipment; in the present embodiment, as figure 1 As shown, the two marking points on the handcart 5 are respectively set at both ends of the upper side of the handcart, which are the first marking point 3 and the second marking point 4 respectively. In this embodiment, the shape of the marking point on the handcart is circular, and the color of the marking point can be red, blue, yellow, etc., which are different from the handcart and have obvious differences. In this embodiment, the number of image acquisition devices is 1; the image acquisition device is defined as the first image acquisition device 1, and the observation range of the first image acquisition dev...

Abstract

The invention discloses a switch cabinet chassis handcart motion state monitoring method, a switch cabinet chassis handcart motion state monitoring system and a device. The method comprises the following steps: through an image acquisition device, acquiring an image of a handcart which is provided with two mark points; when detection on handcart operation speed of certain period of time needs to be executed, calculating actual displacement of the handcart at each moment according to a mark point centroid coordinate in the handcart image acquired at each moment of the period of time by the image acquisition device and an object surface resolution parameter, and calculating speed of the handcart according to the actual displacement of the handcart at each moment in the period of time; when operation straightness of the handcart during certain period of time needs to be detected, acquiring the centroid coordinate in the handcart image at starting time and ending time of the period of timeof the two mark points, and consequently calculating displacement of the two mark pints in the period of time; calculating an rotation angle of the handcart in the period of time according to the displacement of the two mark points in the period of time, and obtaining the operation straightness of the handcart through a value of the rotation angle. With the method, the system and the device provided by the invention, the handcart motion state can be monitored accurately in real time through a non-contact mode.

Description

technical field [0001] The invention belongs to the field of electric power measurement, and in particular relates to a method, system and equipment for monitoring the motion state of a switchgear chassis handcart. Background technique [0002] The switchgear chassis handcart is an actuating device for carrying contacts. Its function is to drive the contact movement through the movement of the handcart to realize the opening and closing actuation. The movement of the chassis handcart is generally realized by manual shaking or motor drive, but due to the influence of factors such as mechanical fit clearance, machining error and long-term wear and tear, the grasp of the movement process and position determination of the handcart have a great impact, and finally affect the handcart. Cognition of working status and discrimination of opening and closing status. [0003] At present, the measurement of the working state of the handcart can only be speculated by indirect physical q...
