Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to an elevator car combination call display panel and combination call method. Background Technology

[0002] Traditional elevator cars have multiple buttons on the display panel that correspond to each floor number. Passengers press the corresponding button to register their call. Since most commercial and residential buildings have between 26 and 33 floors, and some commercial office buildings even have more than 50 floors, the display panel needs to have a large number of buttons. This is not only inconvenient for passengers to find and select, but also increases the size and cost of the display panel. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention proposes an elevator car combination call display panel and combination call method, aiming to enable call operation via combination of number keys, reducing the number of buttons on traditional panels. The specific technical details are as follows:

[0004] The elevator car combination call display panel of the present invention includes a key control area and a display area. The key control area includes a nine-key numeric keypad for calling the elevator individually or in combination, a negative floor key for registering underground floors in combination with the nine-key numeric keypad, a cancel key for canceling registered floor numbers in combination with the nine-key numeric keypad, a car door open key, a car door close key, and an alarm key. The display area includes a display screen, which has an elevator status display area, a current floor display area, and a reserved floor display area. The elevator status display area is used to switch between displaying an up or down indicator, the current floor display area is used to display the current floor number of the elevator car, and the reserved floor display area is used to display several floors that have been registered for calling the elevator.

[0005] The elevator car combination call method of the present invention is based on the above-mentioned elevator car combination call display panel. The method includes the following steps: when registering a ground floor, the target floor number is entered by pressing the 9-key numeric keypad in sequence; when registering a basement floor, the negative floor key is pressed first, followed by pressing the 9-key numeric keypad in sequence to enter the target floor; when canceling a registered ground floor, the cancel key is pressed first, followed by pressing the 9-key numeric keypad in sequence to enter the floor number to be canceled, and then the registration of the corresponding floor is cleared; when canceling a registered basement floor, the cancel key is pressed first, followed by pressing the negative floor key and the 9-key numeric keypad in sequence to enter the floor number to be canceled, and then the registration of the corresponding floor is cleared.

[0006] Compared with the prior art, the advantages of this invention are reflected in the fact that it uses a combination of number keys to call the elevator, reducing the number of buttons on the traditional panel and optimizing the layout of the panel keys. This not only makes it easier for passengers to find and select the corresponding floor, but also greatly reduces the size and cost of the display panel. Attached Figure Description

[0012] The following is in conjunction with the appendix Figures 1 to 5 The following is a further description of the proposed solution:

[0013] See appendix Figures 1 to 4 The elevator car combination call display panel includes a key control area 1 and a display area 2. The key control area 1 includes a nine-key numeric keypad 3 for individual or combined calls, a negative floor key 4 for registering underground floors in combination with the nine-key numeric keypad 3, a cancel key 5 for canceling registered floors in combination with the nine-key numeric keypad 3, a car door open key 6, a car door close key 7, and an alarm key 8. The display area 2 includes a display screen 9, which has an elevator status display area 91, a current floor display area 92, a reserved floor display area 93, and a warning area 94. The elevator status display area 91 is used to switch between displaying an up or down indicator, and can also be used to cycle through the received elevator system information. The current floor display area 92 is used to display the current floor number of the car, the reserved floor display area 93 is used to display several floors that have been registered for calls, and the warning area 94 is used to display a full load indicator.

[0014] See appendix Figure 1 and 5 The elevator car combination call method includes the following steps:

[0015] 1) When registering the floor number, enter the target floor number by pressing the nine-key number keys in sequence; the floor number is generally limited to a maximum of two digits, i.e., 1-99 floors;

[0016] When registering the floor level, the system checks if the second number key is pressed within one second after pressing the first number key. If not, it registers the elevator call based on the key value of the first number key. If so, it continues to record the key value corresponding to the second number key and registers the elevator call based on the combination of the first and second number keys. That is, if the key value corresponding to the first number key is N and the key value corresponding to the second number key is M, then:

[0017] After pressing the first number key, the key value N is obtained and the call is registered for 1 second. If there is no subsequent input, the call is registered with the key value N. If the second number key is pressed, the key value M is obtained and the call is registered with 10*N+M. Since the maximum number of floors above ground is set to two digits, the call is triggered immediately after the second number key is detected, without waiting.

[0018] The number of target floors that have been registered for elevator calls will be displayed simultaneously in the reservation floor display area;

[0019] 2) When registering the basement floor, first press the negative floor key, then press the nine-key number keys in sequence to enter the target floor; the number of basement floors is generally 1-3, that is, the floor number is a single digit;

[0020] When registering for underground floors, the system checks for the touch of a number key within one second after pressing the negative floor button. The negative floor is then marked with the key value of the number key, and the elevator call registration is completed. The target floor number that has been registered for the elevator call is simultaneously displayed in the reserved floor display area.

[0021] Of course, the above method can also be extended to cases where the floor number has more digits. For example, if the floor number is three digits, the first number key is entered to obtain the key value N, which is displayed in the input area on the screen. If the second number key is entered within 1 second to obtain the key value M, it is updated to 10*N+M; if the third number key is entered within 1 second to obtain the key value K, it is updated to 100*N+10*M+K; and so on.

[0022] 3) To cancel a registered floor, first press the cancel button, then press the number keys in sequence within 2 seconds to enter the floor number to be canceled, and then clear the registration of the corresponding floor.

[0023] 4) To cancel a registered basement floor, first press the cancel button, then within 2 seconds press the negative floor button and the 9-key number key in sequence to enter the floor number to be canceled, and then clear the registration of the corresponding floor.

[0024] This invention uses a combination of number keys for elevator call operations. For example, if a passenger wants to go to the 16th floor, they can press the number key "6" within 2 seconds of pressing the number key "1". The floor number "16" will be recognized and registered, and displayed in the reserved floor display area 93 on the screen. If the number key "6" is pressed more than 2 seconds after pressing the number key "1", the floor numbers "1" and "6" will be recognized and registered respectively. Similarly, if a passenger wants to go to the basement parking garage, they can press the number key "1" within 2 seconds of pressing the basement key 4. The floor number "B1" will be recognized and registered, and displayed in the reserved floor display area 93 on the screen. Generally, the combination with the basement key 4 is limited to one number key, which can register floors B1-B9. In reality, parking garages are mostly floors 1-3. If the passenger makes a mistake or does not want to go to the 16th floor, they can press the cancel key 5 and then press the number keys "1" and "6" in sequence to cancel the registration for the 16th floor and remove it from the reserved floor display area 93. The above design effectively reduces the number of buttons in traditional panels, avoids the dozens of buttons on each floor in high-rise buildings, optimizes the panel button layout, makes it easier for passengers to find and select the corresponding floor, and greatly reduces the size and cost of the display panel.

[0025] Furthermore, considering passengers' calling habits and efficiency, there may be situations where two or more people press buttons simultaneously or at intervals of less than one second. Therefore, this application incorporates a video discrimination mechanism based on the above. This mechanism uses a camera to identify and extract the number of people calling the elevator in front of the display panel in real time. When the number of calls equals the number of button presses detected, each button's value is identified as an independent target floor. For example, if two people are detected pressing the number keys "3" and "6" within a one-second interval, it is determined that two people are calling the elevator, and these are recorded as target floors "3" and "6" respectively. This video discrimination mechanism, as an auxiliary mechanism, only works when passengers press buttons simultaneously or at intervals of less than one second, and it applies to single-digit floor calls. When the button press interval is greater than one second, it is considered two separate elevator call registrations.

[0026] Considering the inconvenience for visually impaired people, Braille 10 corresponding to the function or meaning of each key is provided on the key surface of each key in the key control area 1, so that visually impaired people can distinguish the key position when they touch it.

[0027] From the perspective of assembly structure and ease of maintenance, the elevator car combined call display panel includes a flip-open front panel 11 and a back shell 12, which facilitates opening the internal space. The internal space houses a display screen 9, an electronic control main board 13, and an intercom 14 and a camera 15 connected to the electronic control main board 13. The intercom 14 includes a microphone and a speaker. The front panel 11 has a display window 16 adapted to the display screen 9, key holes 17 adapted to the buttons, a sound outlet 18 opposite the intercom 14, and a camera... The display screen 9 and the electronic control motherboard 13 are mounted on the back side of the front panel 11, and are connected by an RS232 data cable 20. The electronic control motherboard 13 is equipped with a button module and a CAN bus module 21 (GTEC188 protocol compatible). The electronic control motherboard 13 is marked with the RX232_LCD interface: 12V pin (display power), GND (display power 0V), RX pin (RS232 communication receiver) and TX pin (RS232 communication transmitter).

[0028] The back cover 12 has a cable hole 22 for cable routing, and the camera hole 19 is covered with a transparent protective plate. The walkie-talkie 14 and camera 15 are used to communicate with the monitoring center after pressing the alarm button 8, and to observe the situation of personnel inside the car via the camera 15, so as to deploy appropriate equipment for rescue. The main electrical control board 13 or the display screen 9 has a TF card slot 23 for updates and upgrades, supporting TF card software upgrades or display interface changes. Copy the manufacturer-provided file (DWIN_SET directory) to the root directory of the TF card, turn off the power, and then insert the TF card into the TF card slot 23. The display will automatically upgrade. After the upgrade is complete, remove the TF card and turn the power back on to operate.
