Description

TECHNICAL FIELD

[0001] The present application relates to a control method, more particularly to a roller coaster speed measurement and deceleration control method. BACKGROUND

[0002] The speed of the roller coaster vehicle when entering the station needs to be accurate. It cannot be too fast, otherwise it may collide with the station and cause an accident, and it cannot be too slow or stopped and then started again, which is too poor for the experience of the amusement. Therefore, the speed detection and deceleration of the non-powered amusement equipment such as the roller coaster before entering the station is very important.

[0003] The conventional method for detecting speed: several groups of discrete sensors are arranged on the deceleration brake track section before entering the station, the running time between two sensors of a certain distance is measured to roughly calculate the vehicle running speed, and the opening and closing of the brake device on the track is controlled to realize speed measurement, deceleration and parking. This method takes the average speed of the vehicle running between the two sensors, so it is difficult to accurately obtain the actual vehicle sliding speed. When the load on the vehicle changes with the passenger occupancy rate, the vehicle speed when entering the station will sometimes be too fast, sometimes too slow, and sometimes stopped, etc., which affects the passenger experience.

[0004] Currently, the patent number 202210219543.7, named "Roller coaster wheel type speed measurement device with contact state self-detection and use method", discloses a speed measurement process by setting an incremental encoder and a speed measurement wheel. However, in the speed measurement process, the speed measurement wheel is installed on the roller coaster and needs to roll on the roller coaster track. However, the speed of the roller coaster is fast during driving, and there are various rapid turns and flips, so the installation structure strength of the speed measurement wheel has very high requirements, and the service life of the speed measurement method is generally insufficient.

[0005] If the speed measurement wheel is set on the track, and the roller coaster body passes through the contact speed measurement method, the roller coaster body is connected one by one, which facilitates turning and sliding on the track. However, the structure of the car bottom determines that the car bottom cannot be provided with continuous driving friction plates, so there is a problem of inaccurate speed measurement of the speed measurement wheel. SUMMARY

[0006] In view of the deficiencies in the prior art, the purpose of the present application is to provide a roller coaster speed measurement and deceleration control method with long service life and accurate speed measurement.

[0007] To achieve the above purpose, the present application provides the following technical scheme: a roller coaster speed measurement and deceleration control method, comprising the following steps:

[0008] Step one, set two encoder speed wheels on the track, and the distance between the two encoder speed wheels is greater than the distance between the two seats of the roller coaster car body;

[0009] Step two, set a controller in communication connection with the two encoder speed wheels, receive the speed data output by the two encoder speed wheels, and compare the two speed data in real time, select the speed data with larger speed value as the driving speed of the roller coaster;

[0010] Step three, compare the speed value of the driving speed obtained in step two with the set value set in it, if the speed value is less than the set value, the roller coaster brake is fully opened, if the speed value is greater than the set value, the roller coaster brake is fully closed.

[0011] As a further improvement of the present application, it further comprises the following steps:

[0012] Step four, set a discrete sensor on the track before entering the station, and communicate the sensor with the controller;

[0013] Step five, detect the speed of the roller coaster when entering the station by the time measured by the discrete sensor, and when the speed is overspeed, judge that the brake is out of control, and the controller controls the safety brake to close.

[0014] As a further improvement of the present application, the encoder speed wheel set in step one comprises a speed measuring base, a speed measuring swing rod, an encoder and a roller, the speed measuring base is fixedly installed on the external track, one end of the speed measuring swing rod is hinged on the speed measuring base, the roller is rotatably fixed on the other end of the speed measuring swing rod, the encoder is also fixed on the end, and the output shaft of the encoder is coaxially fixed with a rotating shaft, the rotating shaft passes through the end of the speed measuring swing rod, and then is coaxially fixed with the roller to serve as the rotating shaft of the roller, the middle part of the speed measuring swing rod is hinged with a reset spring cylinder, one end of the reset spring cylinder is hinged on the speed measuring swing rod, and the other end is fixed on the speed measuring base to drive the speed measuring swing rod to be lifted upward.

[0015] As a further improvement of the present application, the end of the rotating shaft away from the encoder is coaxially sleeved with a damping device.

[0016] As a further improvement of the present application, the damping device comprises a damping shell, a damping wheel and a brake ring, the damping wheel is coaxially sleeved on the rotating shaft, the brake ring is fixed in the damping shell, the damping wheel is rotatably arranged in the brake ring, and the wheel surface of the damping wheel abuts against the inner ring wall of the brake ring.

[0017] As a further improvement of the present application, the speed measuring base is also fixed with a bumper.

[0018] The beneficial effects of the present application, by the setting of step one, can be realized in the process of roller coaster driving, when running to the track that needs to be measured, the encoder speed wheel can always keep in contact with the friction plate of the car bottom, thereby realizing the effect of accurate speed measurement result, and compared with the way in the prior art, it will not be affected by the driving path and load of the roller coaster, and the problem of insufficient service life will not be caused, so as to effectively realize the speed measurement and deceleration of the roller coaster.

[0025] Step one, two encoder speed wheels are arranged on the track, and the distance between the two encoder speed wheels is greater than the distance between the two seats of the roller coaster car body, as shown in Figure 2 ;

[0026] Step two, a controller is arranged in communication connection with the two encoder speed wheels, receives the speed data output by the two encoder speed wheels, and compares the two speed data in real time, and selects the speed data with larger speed value as the driving speed of the roller coaster;

[0027] Step three, the speed value of the running speed obtained in step two is compared with the set value set inside, if the speed value is less than the set value, the roller coaster brake is fully opened, if the speed value is greater than the set value, the roller coaster brake is fully closed, the setting of step one is adopted, when the roller coaster passes through the encoder speed measuring wheel, the encoder speed measuring wheel can always keep in contact with the friction plate under the roller coaster, so that the rotation speed of the encoder speed measuring wheel is always related to the sliding speed of the roller coaster, effectively ensuring the accuracy of the speed measurement result, and then through step two, the speed value of the roller coaster can be selected, and then through step three, the speed control can be simply and effectively realized, so compared with the existing technology, the speed measurement result is accurate, and is not affected by the running way and load of the roller coaster, and the service life is longer.

[0028] As an improved embodiment, it further comprises the following steps:

[0029] Step four, a discrete sensor is arranged on the approach track, and the sensor is communicatively connected with the controller;

[0030] Step five, the speed of the roller coaster when entering the station is calculated by detecting the time when the roller coaster passes through the discrete sensor, and when the speed is overspeed, it is judged that the brake fails, and the controller controls the safety brake to close, through the setting of the above steps, the existing sensor speed measurement method can be used as an insurance to avoid accidents caused by the roller coaster not slowing down in time when the encoder speed measuring wheel fails.

[0031] As an improved embodiment, refer to Figure 3 The encoder speed measuring wheel arranged in the step one comprises a speed measuring base 1, a speed measuring swing rod 2, an encoder 3 and a roller 4, the speed measuring base 1 is fixedly installed on the external track, one end of the speed measuring swing rod 2 is hinged on the speed measuring base 1, the roller 4 is rotatably fixed on the other end of the speed measuring swing rod 2, the encoder 3 is also fixed on the end, and the output shaft of the encoder 3 is coaxially fixed with a rotating shaft, the rotating shaft passes through the end of the speed measuring swing rod 2, and then is coaxially fixed with the roller 4 to serve as the rotating shaft of the roller 4, the middle part of the speed measuring swing rod 2 is hinged with a reset spring cylinder 5, one end of the reset spring cylinder 5 is hinged on the speed measuring swing rod 2, and the other end is fixed on the speed measuring base 1 to drive the speed measuring swing rod 2 to be lifted upward, through the setting of the above structure, the roller 4 can effectively keep in contact with the friction plate under the car through the elastic upward lifting of the speed measuring swing rod 2 by the reset spring rod 5.

[0032] As a specific embodiment of the improvement, one end of the shaft back encoder 3 is coaxially sleeved with a damping device 6. Through the arrangement of the damping device 6, when the roller 4 is in the gap between the two seats, the effect of rapid braking can be achieved, and the problem that the final measured speed is greater than the actual speed of the roller coaster due to further acceleration when contacting next time because of inertia rolling can be avoided.
