Description

Technical Field

[0001] The invention relates to the technical field of zipline equipment, in particular to the technical field of a pulley release control system with interlocking protection. Background Art

[0002] The non-powered amusement zipline has become a common entertainment project in amusement parks. The safety of the zipline has attracted more and more attention. Some of the safety accidents are caused by the staff's improper operation. When the arrival station is not ready, the staff at the departure station releases the zipline too early. For straight ziplines, this will cause the front and rear passengers to collide with each other; for reciprocating ziplines, this will cause passengers to not have time to get off the zipline, thus causing safety accidents.

[0003] To address this issue, new technical requirements for the interlocking protection of the zipline release device have been added to the "GB / T 31258-2024 General Technology for Zipline" which will be implemented soon. The requirements state that the operator at the arrival station needs to confirm that the passengers have left safely and then operate the release button. The operator at the departure station can only activate the release interlocking device to release the vehicle after receiving the release signal.

[0004] At present, there are two common means of releasing the pulley in China: one is a simple plate hook fixed to the wire rope at the departure station by gravity or spring reset, and the other is to use a safety lock to fix the pulley to prevent it from sliding down. These manual operation methods have major safety hazards, especially when the operator at the departure station fails to correctly confirm the readiness of the arrival station or the safety of the passengers and still mistakenly releases the pulley, which can easily lead to accidents. In the existing technology, there is no effective communication between the departure station staff and the arrival station staff, and no collaborative operation can be achieved, and the pulley cannot be released only on the premise of ensuring that the arrival station and the departure station are ready. Summary of the invention

Through the intelligent electrical control structure and the coordinated operation of the staff at the departure station and the arrival station, the entire release process can be accurately controlled. The release instruction will only be executed when the safety conditions are met, thereby effectively reducing the safety risks caused by human negligence.

[0037] like Figure 2 As shown, the departure station remote control box and the arrival station remote control box have the same shape and size, and the front of the remote control box housing 12 includes an OLED display screen 14, three LED indicator lights 16 and an operation button 17. The operation button 17 includes 09 numeric keys, a "*" key and a "#" key. A power switch 15 is installed on the right side of the remote control box housing 12, and an antenna 13 is installed on it.

[0038] like Figure 4 As shown, the circuit system in the departure station remote control box includes the departure station MCU 198, the departure station buzzer drive circuit, the departure station power supply circuit 197, the departure station OLED display module 192, the departure station LED indicator 193, the departure station button 194, the departure station short-distance wireless communication module 195 and the departure station LORA long-distance wireless communication module 196. The buzzer drive circuit is connected to the arrival station buzzer 191. The departure station LORA long-distance wireless communication module 196 is connected to the antenna 13. The departure station MCU 198 includes a USART module, an I / O port, an SPI module, a TIM module and a FLASH module. The USART module is connected to the departure station LORA long-distance wireless communication module 196, the I / O port is connected to the departure station OLED display module 192, the departure station LED display light 193 and the departure station button 194, and the switch of the buzzer sound regularity is realized through the TIM module and the I / O port; the SPI module is connected to the departure station short-distance wireless communication module 195, and the FLASH module stores the password and working steps of the departure station remote control box.

[0039] like Figure 5As shown, the arrival station remote control box control system includes an arrival station MCU 207, an arrival station buzzer drive circuit, an arrival station power supply circuit 206, an arrival station OLED display module 202, an arrival station LED indicator 203 and an arrival station button 204, and an arrival station LORA long-distance wireless communication module 205. The buzzer drive circuit is connected to the arrival station buzzer 201. The arrival station LORA long-distance wireless communication module 205 is connected to the antenna 13.

[0040] The normal operation process of the pulley release device with interlock protection is as follows: Figure 7 As shown, here we take the release control of a reciprocating cableway as an example. The entire control system is controlled by the motor direct control box, the departure station remote control box and the arrival station remote control box, and is implemented in 5 steps. No matter which step the process is carried out, it will be saved in the FLASH module.

[0041] See also Figure 6 The pulley releasing device includes a releasing hook 21 and a mounting base 22. The mounting base 22 is fixed on the pulley. The middle part of the releasing hook 21 is hingedly fixed to the mounting base 22 through a hinge seat. One end of the releasing hook 21 is provided with a hook head for cooperating with the pulley, and the other end is provided with an electric push rod 23 for driving the releasing hook 21 to flip back and forth around the hinge seat. A fixing component for fixing the electric push rod 23 is provided on the mounting base 22.

[0042] The specific operation of the system in this embodiment includes the following steps: Steps Step 1: The system is powered on, and the departure station MCU and arrival station MCU of the departure station remote control box and the arrival station remote control box read the initial information stored in their respective FLASH modules, including the password, the working step when the system was powered off last time, and the last working electric push rod 23. At the same time, a signal is sent to light up the three LED indicator lights 16, and the OLED display screen 14 displays the text "Please enter the password". When the staff of the two stations are ready, enter the three-digit password and double-click the "#" key in the operation button 17. If it is correct, the OLED display screen 14 will display the text "Departure station: Unconfirmed, Arrival station: Unconfirmed", and only the green light of the LED indicator light 16 will be on.

[0043] Step 2: The departure station staff presses the number key "1" in the departure station button 194, and the departure station MCU sends a confirmation signal, which is sent through the USART module and the departure station LORA long-distance wireless communication module 196 via the antenna 13. After the arrival station LORA long-distance wireless communication module 205 receives the signal, it is transmitted to the arrival station MCU 207 through the USART module. Through the I / O port, the arrival station LED indicator 203 only lights up yellow, and the arrival station buzzer 201 sounds for 0.5 seconds. At this time, the OLED display screens 14 of the two stations display the text "Departure station: confirmed, arrival station: unconfirmed".

[0044] Step 3: After the arrival station staff confirms that the surrounding environment is safe, they press the number key "1" in the arrival station button 204. The arrival station LORA long-distance wireless communication module 205 sends a signal through the antenna 13. After the departure station LORA long-distance wireless communication module 196 receives it, the departure station MCU198 sends a signal through the I / O port, the departure station LED indicator 193 only lights up yellow, and the departure station buzzer 191 sounds for 0.5 seconds. At this time, the OLED display screens 14 of the two stations display the text "Departure station: confirmed, arrival station: confirmed".

[0045] Step 4: The departure station staff presses the number key "1" in the departure station button 194 again, and the departure station MCU198 sends a pulley release signal, which is sent through the USART module, the departure station LORA long-distance wireless communication module 196 through the antenna 13, and through the SPI module and the departure station short-distance wireless communication module 195 to the motor direct control box. After the arrival station LORA long-distance wireless communication module 205 receives the signal, the arrival station MCU207 sends a command through the I / O port to make the arrival station buzzer 201 sound for 0.5 seconds. At this time, the departure station LED light 193 and the arrival station LED light 203 are only red, and the two station OLED display screens 14 display the text "Departure station: pulley release, arrival station: confirmed". In addition, after the direct control box short-distance wireless communication module 184 receives the signal, the direct control box MCU186 sends a command to the direct control box motor drive circuit 181 through the SPI module, driving the electric push rod 23 to push the long arm end of the release hook 21 to rise, and the pulley leaves the departure station.

[0046] Step 5: After the trolley arrives safely, the arrival station staff presses the number key "1" in the arrival station button 204 again, and the arrival station MCU207 sends an arrival signal, which is sent through the arrival station LORA long-distance wireless communication module 205 through the antenna 13. After the departure station LORA long-distance wireless communication module 196 receives it, the departure station MCU198 sends an arrival signal through the I / O port, and the departure station buzzer 191 sounds for 0.5 seconds. At this time, the departure station LED light 193 and the arrival station LED light 203 are only green, and the two station OLED display screens 14 return to the text "Departure station: Unconfirmed, Arrival station: Unconfirmed".

[0047] The above five steps are the normal workflow. If an emergency occurs in the zipline facility during steps 2 to 5, any station staff member presses the "#" key in the operation button 17, and the two remote control boxes MCU send out an emergency signal, and the OLED display screen 14 displays the text "emergency" through the I / O port, and the LED indicator 16 lights up three lights: green, yellow, and red; the MCU controls the TIM module to make the buzzer send out multiple indirect alarm sounds; the MCU controls the SPI module, the departure station short-distance wireless communication module 195, the direct control box MCU186, and the motor drive circuit 181 to drive the electric push rod 23, so that the long arm end of the release hook 21 stops running, and the other operation buttons of the departure station and arrival station remote control boxes will become invalid, and the current process of the device will be interrupted. After pressing the "#" key again, the long arm end of the release hook 21 drops again, and the workflow returns to step 1.

[0048] In addition, in an emergency, the motor direct control box can also be directly operated to control the mechanical device. The staff presses the emergency button 9, and the external interrupt function of the direct control box MCU186 is triggered through the EXTI module. The direct control box MCU186 sends an emergency signal, and the emergency status indicator light 2 is turned on through the I / O port. Press the slide release button 4, the direct control box MCU sends a release signal, and the motor drive circuit 181 drives the electric push rod 23 to move, so that the release hook 21 rises, and the signal is through the I / O port to light up the slide release indicator light 5. The operation method of pressing the slide blocking button 7 is the same. Rotate the emergency button 9 again to reset it, and the reset signal goes through the EXTI module and the direct control box MCU186 to turn off the emergency status indicator light 2, and all other buttons on the direct control box are invalid.

[0049] The operation of changing the password of the remote control box at the departure station and the arrival station is as follows: after entering the correct three-digit password, press the "#" key in the operation button 17, and then press the "*" key three times. The OLED display screen 14 will display the text "Please enter a new password". Enter a new three-digit password and press the "#" key to end. The new password is stored in the FLASH module of the MCU, and the workflow returns to step one. Embodiment 2:

[0050] See also Figure 8 Fig.11On the basis of the first embodiment, a pulley is provided on the zip line, and the pulley further includes an active deceleration mechanism provided on the pulley, and the active deceleration mechanism includes an active deceleration box 30, and a deceleration box MCU, a first positioning module 301 electrically connected to the deceleration box MCU, and a deceleration box LORA wireless communication module 302 are provided in the active deceleration box 30, and the deceleration box MCU is wirelessly connected to the arrival station LORA long-distance wireless communication module 205 through the deceleration box LORA wireless communication module 302. A deceleration parachute 303 and an umbrella tube 304 for accommodating the deceleration parachute 303 are also provided on the back of the active deceleration box 30, and an opening for the deceleration parachute 303 to pass through is provided on the end of the umbrella tube 304 away from the pulley, and an umbrella driving mechanism for driving the deceleration parachute 303 to detach from the umbrella tube 304 is also provided in the umbrella tube 304, and the deceleration box MCU is control-connected to the umbrella driving mechanism, and an arrival station positioning module 208 electrically connected to the arrival station MCU207 is provided in the arrival station remote control box; After the pulley sets off, the deceleration box MCU continuously obtains the positioning information of the first positioning module 301 and calculates the current speed. At the same time, the deceleration box MCU continuously obtains the positioning information of the arrival station positioning module 208 and calculates the distance between the first positioning module 301 and the arrival station positioning module 208. When the distance is less than the preset safety value and the current speed is greater than the preset safety speed, the deceleration box MCU controls the umbrella driving mechanism to drive the deceleration parachute 303 to open. In this embodiment, an active deceleration mechanism is set on the pulley, and the real-time speedometer of the pulley and the distance between the pulley and the arrival station are obtained to analyze whether there is danger. When there is danger, the deceleration parachute 303 can be controlled by the umbrella driving mechanism to open immediately, thereby decelerating the pulley, which can improve safety and avoid accidents caused by the pulley's excessive speed when entering the arrival station. The deceleration parachute 303 is automatically controlled, with a higher degree of intelligence and better protection effect.
