Multi-switch voting level control method for revolving lift car of Ferris wheel

Abstract

The invention relates to a multi-switch voting level control method for a revolving lift car of a Ferris wheel. An inner ring of the lift car is connected with a double closed-loop control system which drives the inner ring to rotate at the same angular velocity in an opposite direction relative to the Ferris wheel, and the system comprises a controller, a motor driver and a driving motor; the controller adopts the multi-switch voting level control method for calculating an absolute value of the difference of every two signals of three inclination detecting sensors respectively, the absolute values of the differences are compared with a signal set value to determine whether or not the signals of the three inclination detecting sensors are all normal, one of the normal signals of the normalinclination detecting sensors is selected as a signal source, the controller drives the motor driver and the driving motor to work according to the signal of the source signal, acceleration and deceleration control is performed on the lift car, and therefore the purpose of horizontal adjustment is achieved. By means of the method, not only can whether or not the sensors are invalid be quickly andeffectively determined, but also specific fault sensors can be accurately determined, the probability of alarming for accidental shutdown is decreased, and the safety of the system is improved.

Description

【Technical field】 [0001] The invention relates to a ferris wheel for entertainment, in particular to a multi-switch voting level control method for a revolving car of the ferris wheel. 【Background technique】 [0002] In the amusement industry, Ferris wheel amusement equipment has been put into use in more and more venues with the development of the economy. And along with the raising of people's quality of life, also have higher requirement to the comfort and safety of Ferris wheel car, therefore Ferris wheel car also needs to be updated. [0003] Most of the traditional ferris wheel cars use gravity adaptive technology to keep the car level only by the weight of the car itself and the gravity of passengers. Since this technology has no other power to participate, if the passenger inside the car has an unbalanced load, the car cannot guarantee a 100% level, and the anti-interference performance of external force is weak, so the car balance control is performed by adding a d...

AI Technical Summary

Problems solved by technology

In the prior art, a single or two inclination detection sensors are generally used for detection, but there are certain problems in both detection methods: once the sensor fails in the single detection method, the system cannot judge that the sensor has failed, and the sensor failure will cause the level correction system to fail. Wrong control will cause the car to tilt seriously, causing catastrophic consequences; another example is that although the double sensor detection can judge the failure of the sensor, it cannot judge the specific faulty sensor, and the failure of a single sensor will cause the equipment to alarm and stop, causing rescue. Therefore, how to get Reliable inclination detection results are the key to the entire car balance control
