Description

Technical Field

[0001] The present invention relates to the technical field of elevator control, and in particular to an elevator system convenient for blind people to take and a control method thereof. Background Art

[0002] At present, the floor indicator buttons in elevators mainly use bright lights to display the selected floor. Passengers select the destination floor by pressing the buttons, and the destination floor indicator lights up. When the destination floor is reached, the voice control prompts the number of floors reached by the people in the elevator, and the floor indicator goes out. The above elevators do not take into account the use of elevators by blind people. If there are companions or other passengers in the elevator, they can ask others for help to complete the ride. If the blind use the elevator alone, it will be more difficult to display. Considering the use of blind people, some elevators are equipped with Braille prompt information on the internal call button. The blind can call the elevator according to the Braille instructions, but they cannot determine whether the internal call is successfully registered. If the elevator reaches the destination floor, if there is no station announcement bell or even if there is a station announcement bell, it is too crowded to hear it clearly, it will lead to an inability to accurately judge whether the destination floor has been reached. Summary of the invention

[0003] In order to overcome the defects and shortcomings of the prior art, the present invention provides an elevator system and a control method thereof which are convenient for the blind to take the elevator, which can solve the problem of inconvenience for the blind to take the elevator. It can not only inform the blind passengers whether the elevator call is successful, but also prevent the problem that the blind passengers cannot accurately reach the destination floor because they cannot hear the arrival bell when there are too many passengers in the car.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] The present invention provides an elevator system that is convenient for blind people to ride, comprising: an elevator main control panel, an interior call main control panel, a car operation panel and a vibration device;

[0006] The car operating panel is connected to the elevator main control board, and the elevator main control board is connected to the vibration device.

[0007] The car operation panel is provided with a blind elevator button and an internal call button, the blind elevator button is provided with Braille, the internal call button is connected to the internal call main control board, and the internal call main control board is connected to the elevator main control board;

[0008] The elevator main control board is connected to the vibration device, and the elevator main control board is used to receive the internal call registration floor information of the internal call main control board and control the vibration device to vibrate;

[0009] The vibration device is arranged on the car bottom plate.

[0010] As a preferred technical solution, the car floor adopts a double-layer structure, and the vibration device is arranged on the upper layer of the car floor or between the upper and lower layers.

[0011] As a preferred technical solution, the upper and lower layers of the car floor are connected by stud supports, and the studs are arranged at the four top corners of the bottom of the car.

[0012] As a preferred technical solution, the vibration device adopts a patch motor, and the patch motor is arranged on the upper layer of the car bottom.

[0013] As a preferred technical solution, the vibration device adopts a crank device, the crank device is connected to a drive motor, the drive motor is arranged between the upper and lower layers of the car floor, and the crank device is arranged at a central position in the middle of the car floor.

[0014] The present invention also provides a control method for an elevator system that is convenient for blind people to ride, comprising the following steps:

[0015] When the elevator main control board receives the internal call command from the internal call main control board, it first determines whether the blind passenger's elevator button is triggered. If the blind passenger's elevator button is triggered, the elevator main control board controls the vibration device on the car floor to vibrate to remind the blind passenger that the destination floor is successfully registered.

[0016] When the elevator reaches the destination floor, the elevator main control board controls the vibration device on the car floor to vibrate, reminding the blind passenger that he has reached the destination floor;

[0017] When the internal call registration is successful and when the destination floor is reached, the vibration device has the same number of vibrations, but different vibration frequencies and amplitudes.

[0018] As a preferred technical solution, the elevator main control board controls the vibration of the vibration device of the car floor, and the specific steps include:

[0019] When the Nth blind passenger presses the blind boarding button and the internal call button to the destination floor, the elevator main control board first determines whether there is a previous blind passenger registered for the destination floor. If it has been registered, and the elevator car bottom vibration device vibrated a times during the previous registration, the car bottom vibration device will also vibrate a times at this time. If the destination floor that the blind passenger wants to reach has never been registered, the number of vibrations this time is determined based on the previous registration of blind passengers. If the maximum number of registrations before is b, the number of vibrations of the car bottom vibration device is b+1 at this time.

[0020] As a preferred technical solution, the vibration times of the vibration device are the same when the internal call registration is successful and when the destination floor is reached, but the vibration frequency and amplitude are different. The specific steps include:

[0021] When the internal call registration is successful, the vibration interval of the vibration device is set to 1s, and the duration of each vibration is 0.5s; when arriving at the destination floor, the vibration interval of the vibration device is set to 0.5s, and the duration of each vibration is 0.2s.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Example

[0028] like Figure 1 As shown, this embodiment provides an elevator system that is convenient for blind people to ride, including: an elevator main control panel, an interior call main control panel, a car operation panel and a vibration device;

[0029] The car operating panel is connected to the elevator main control board, and the elevator main control board is connected to the vibration device;

[0030] The car operation panel is provided with blind elevator buttons and internal call buttons, and all the blind elevator buttons are provided with Braille. The elevator buttons and internal call buttons are used for passenger internal call registration. The internal call buttons of the car operation panel are connected to the internal call main control board. The internal call main control board obtains the internal call registration floor information on the car operation panel and sends it to the elevator main control board;

[0031] The elevator main control board is used to control the operation of the elevator, receive the internal call registration floor information from the internal call main control board, and control the vibration of the vibration device;

[0032] The vibration device is arranged on the car bottom plate. The vibration device of this embodiment adopts a patch motor, and the patch motor is arranged on the upper layer of the car bottom plate.

[0033] The vibration device of this embodiment can also adopt a crank device, which is driven by a motor to generate vibration. The motor is installed between the upper and lower layers of the car floor, and the crank device is set at the center position in the middle of the car floor.

[0034] The car floor of this embodiment adopts a double-layer structure, and the upper and lower layers of the car floor are supported and connected by studs, and the studs are arranged at the four top corners of the bottom of the car.

[0035] When a blind person takes the elevator, he / she must first press the blind elevator button, then press the internal call button, and then press the floor he / she wishes to reach. When the elevator main control board receives the internal call command, it first determines whether the blind elevator button has been triggered. If the blind elevator button has been triggered, the elevator main control board controls the vibration device on the car floor to vibrate to remind the blind passenger that the destination floor has been successfully registered. When the elevator reaches the destination floor, the elevator main control board controls the vibration device on the car floor to vibrate to remind the blind passenger that the destination floor has been successfully registered. Here, in order to enable blind passengers to easily distinguish whether the vibration of the elevator car floor is a successful internal call registration or arrival at the destination floor, the vibration frequency and amplitude of the car floor vibration device when the internal call registration is successful are set to be different from the vibration frequency and amplitude after arrival at the destination floor.

[0036] The elevator system of this embodiment can serve both the general public and the blind. The general public can directly press the internal call button to take the elevator, while the blind need to press the blind elevator button first and then press the internal call button. Therefore, when the elevator main control board receives the internal call command, it must first determine whether the blind elevator button is triggered.

[0037] The specific control steps of the elevator system for the blind in this embodiment are as follows:

[0038] When the elevator is running, if there are more than 1 blind passengers in the car, the specific processing is as follows:

[0039] When the first blind passenger presses the blind elevator button and the destination floor, the elevator car bottom vibration device vibrates once, and when it reaches the destination floor, the elevator car bottom also vibrates once to remind the passenger that it has reached the destination floor;

[0040] When the second blind passenger presses the blind elevator button and the destination floor, if it is the same as the first blind person's destination floor, the elevator car floor vibrates once, if not, the elevator car floor vibrates twice. After reaching the destination floor, when the passenger feels the same vibration as when registering, it indicates that the destination floor has been reached;

[0041] When the Nth blind passenger presses the blind button and the destination floor, the elevator main control board first determines whether the destination floor has been registered for the blind passenger. If it has been registered, and the elevator car bottom vibration device vibrated a times during the previous registration, then the elevator car bottom vibration device will also vibrate a times this time. If the destination floor that the blind passenger wants to reach has never been registered, the number of vibrations this time is determined based on the previous registration of the blind passenger. If the maximum number of registrations before is b, then the number of vibrations this time is b+1.

[0042] In this embodiment, when the internal call is successfully registered and when the destination floor is reached, the elevator main control board sends different signals to the vibration device. The vibration device has a control module. The control module in the vibration device generates different vibration frequencies and amplitudes according to different controls of the received signals. That is, when the internal call is successfully registered and when the destination floor is reached, the number of vibrations is the same, but the vibration frequencies and amplitudes are different.

[0043] In this embodiment, when the internal call registration is successful, the vibration interval of the vibration device is set to 1s, and each vibration lasts 0.5s; when arriving at the destination floor, the vibration interval of the vibration device is set to 0.5s, and each vibration lasts 0.2s.

[0044] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
