A three-dimensional visualization simulation test method for elevator cage movement

Abstract

The invention discloses a 3D visual simulation test method for cage movement of a lift and relates to the technical field of a construction lift. The kinetic equation and the kinematical equation of the cage are set up through analyzing the movement process of the cage of the construction lift as well as the weight, running speed, acceleration, deceleration and other parameters of the cage; a 3D visual simulation system for the movement process of the cage of the construction lift is designed by unity3d software; the system can assist electronic control engineers to select the models of a frequency converter and a three-phase asynchronous motor; finally the virtual simulation test is performed in the 3D visual simulation system through combining the mechanical characteristics of the three-phase asynchronous motor so as to verify whether the model selection meets the requirements; and then the design of the electric control system of the construction lift is completed; and the purposesof saving energy, reducing cost and improving efficiency are realized.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to a three-dimensional visual simulation test method for the motion of an elevator cage. Background technique [0002] With the rapid development of the national economy in recent years, construction elevators also play a huge role in the construction field, especially for large projects and high-rise building scenes, the use of construction elevators is particularly important. The construction hoist is a construction machine that is commonly used in the construction process of buildings to carry people and cargo. It can greatly improve construction efficiency and save construction time. [0003] With the development of electronic technology and the improvement of people's requirements for the performance, efficiency, maintenance and safety of construction elevators, the main trend is the electrical control system of construction elevators composed of PLC control modu...

Problems solved by technology

However, in the actual operation process, due to the experience and estimation of the electronic control engineer, there are often errors. When reducing the power pre-setting, it is easy to appear that the selection of the motor does not meet the actual requirements. In the actual test process, it is easy to cause failures, errors, etc. , and even accidents

[0005] To sum up, the design of the electrical control system of construction elevators mainly relies on the experience of electrical engineers. During the selection process of three-phase asynchronous motors, high-power three-phase AC asynchronous motors are often selected, which greatly improves the power reserve. , which not only increases the power of the frequency converter correspondingly, increases the cost, but also tends to cause the situation of "big horse-drawn carts" and wastes electric energy

The debugging and testing process of the electrical control system needs to be combined with the actual construction elevator equipment, which is prone to failures, errors, etc. In the case of incomplete protection measures, it is easy to cause physical damage or safety accidents for debugging personnel, which has high testing costs. Low efficiency and other disadvantages
