Description

Elevator operation system using non-contact switch

The present invention relates to an elevator operating method and an elevator operating system. More specifically, it relates to an elevator operation method and an elevator operation system including an operation panel using a non-contact switch.

As a number of unspecified persons touch the buttons on the operation panel outside and inside the elevator, infection by bacteria or pathogens may occur.

Hereinafter, an elevator operating method and an elevator operating system using a non-contact switch according to the present invention will be described.

In this regard, Figure 1b shows the switch and the LED in the elevator button according to the present invention. Referring to FIGS. 1A and 1B, when the elevator button is pressed and the switch is pressed, K1 and K2 are turned on, so that an operation corresponding to the elevator button may be performed. In this case, when K1 and K2 are conducted by the switch, light may be emitted through the LED connected to D1.

Meanwhile, a non-contact elevator switch equipped with an optical sensor according to the present invention will be described as follows. In this regard, Figure 2a shows a modified example of the elevator external operation panel according to the present invention. On the other hand, Figure 2b shows a modified example of the elevator interior operation panel according to the present invention. In addition, Figure 3 shows the infrared sensor and the LED provided in the elevator button according to the present invention.

Referring to FIG. 2A, the up button 110a and the down button 110b of the external operation panel 100 may be disposed in an inner area at a predetermined interval based on the body of the external operation panel 100. The up button 110a and the down button 110b may be configured to utilize the external operation panel 100 before the change. The up button 110a and the down button 110b may be molded products of the same size and may be disposed in the inner area of the external operation panel 100.

2B, the open button 210a, the close button 210b of the internal operation panel 200, and a plurality of buttons 220 corresponding to the layer to be stopped are predetermined based on the body of the internal operation panel 200. It can be arranged in the inner area by the interval. The open button 210a, the close button 210b, and the plurality of buttons 220 may be configured to utilize the internal operation panel 200 before the change. The open button 210a, the close button 210b, and the plurality of buttons 220 may be formed of the same sized injection material and may be disposed in the inner area of the internal operation panel 200.

As described above, FIG. 3 shows a configuration in which a sensor and an LED are operatively coupled to the external operation panel shown in FIGS. 2A and 2B. Meanwhile, FIG. 4 shows a detailed configuration of an elevator operating system according to an embodiment of the present invention.

Referring to FIGS. 2A to 3, the infrared transmission/reception sensor 120a may be manufactured as a separate injection material next to the button for each layer and attached thereto. In this regard, when each elevator button (110a, 110b, 210a, 210b, 220) is pressed within a predetermined distance (e.g., 1cm) for more than a predetermined time (e.g., 0.5 seconds), the button is pressed. Can be. On the other hand, the infrared transceiving sensor 120a constitutes the transmitting unit, and a photodiode such as the LED 130a may constitute the receiving unit.

Accordingly, the present invention uses a non-contact elevator button (switch) that operates when a hand or an object is placed 2 cm in front of the elevator button (switch) surface by mounting a transmission/reception optical sensor. 2 to 4, the elevator operation system may be configured to include an operation panel 100 and 200, a transmission unit 120, a reception unit 130, and a control unit 300. In addition, the elevator operation system may be configured to further include a driving unit 410 and an output unit 420.

Specifically, the signal transmitted from the transmitter 120 may receive a signal reflected from a hand or object that is 2 cm (adjustable) in front of the elevator button surface, at the receiver 130. By analyzing the signal received by the receiving unit 130, the control unit 300 processes whether or not a corresponding specific button is pressed, and the output unit 420 operates through the driving unit 410, so that an operation can be performed in response to the corresponding button. have. In addition, the control unit 300 may control the strength of a transmission/reception signal through ADC conversion and may also perform functions such as preventing pressing of an adjacent button. Regarding the transmission and reception signal strength control, the control unit 300 controls the transmission signal strength with the ADC (Analog Digital Converter) of the MCU to prevent the button from being pressed incorrectly when the elevator button is too close to a person.

In order to control the current flowing through the infrared transmitter and receiver PHODE DIODE, the amount of current can be adjusted by using a resistor. When transmitting an infrared LED and receiving a PHODE DIODE, it may be difficult to precisely control each transmission and reception in order to operate at a distance of 1-2cm due to a large difference in signal strength. Also, even if the input constant voltage is used, if the voltage value changes even a little, the signal value transmitted from the infrared transmitter may change. For example, if the operating distance is 2cm, the operation distance is 1cm in some cases and 3cm in some cases, and there is a problem that the button is pressed when a person goes near the elevator button.

Therefore, in the elevator operation method using the non-contact switch of the present invention, the transmission unit 120 can generate a current to stably have a precise current value by using a constant current method even if the input voltage is fluctuated. In addition, the receiving unit 130 has the advantage of precisely controlling the received voltage value in the CPU ADC in 10 bits (256 steps) to adjust the deviation of the transmit/receive strength of the infrared sensor, respectively. Also. Since the elevator operation button can be freely adjusted for each 1-2 cm, it is possible to solve the problem that the button is pressed or not pressed according to the distance between the user's hand and the button, contrary to the user's intention.

In this regard, FIG. 5 shows the configuration of a transmitting/receiving unit and a control unit including a transmission unit infrared sensor, a receiving unit photodiode, and another circuit according to the present invention. Referring to the above-described technical features and configurations and Figs. 2A to 5, the elevator operation system according to the present invention will be described as follows. The elevator operation system may be configured to include an operation panel 100 and 200, a control unit 300 and a driving unit 400. Meanwhile, the controller 300 may include an analog digital converter (ADC) 310 that performs analog digital conversion (ADC). In addition, the control unit 300 may further include a CPU 320 that is operatively coupled to the ADC 310 and performs elevator button input recognition and control. Here, the controller 300 including the ADC 310 and the CPU 320 may be implemented as a micro control unit (MCU).

The operation panels 100 and 200 may be configured to control the stopping of the elevator and opening and closing of the doors outside or inside the elevator. The controller 300 is configured to be operable with the operation panels 100 and 200, and based on a user input to the plurality of buttons of the operation panels 100 and 200, a sensor 120a and a diode ( 130a). Meanwhile, the driving unit 410 may perform driving control associated with stopping the elevator and opening and closing the door according to a result determined based on a user input.

The controller 300 may control the current intensity within a certain range when an object approaches a specific button surface within a certain distance from among the plurality of buttons and the input voltage is changed. Specifically, when the input voltage is changed, the controller 300 can control the current intensity generated by the sensor 120a within a certain range through the constant current circuit 120b connected to the sensor 120a of the transmitter 120. have.

On the other hand, the controller 300 controls the ADC voltage at the point where the diode 130b and the resistor 130b of the receiver 130 are connected to a predetermined number of bits or more, thereby controlling the current intensity deviation in the sensor 120a. have. Accordingly, when the ADC voltage is maintained above the threshold voltage for a predetermined time or longer, the controller 300 may determine that a specific button has been pressed.

In this regard, FIG. 6 shows a flowchart of a control operation according to reading/detecting an ADC voltage value according to an embodiment of the present invention. Referring to FIG. 6, it may be determined whether the ADC voltage reaches a threshold voltage V_th or a threshold voltage V_th within a predetermined range by performing the ADC voltage reading/detecting process S110 (S120). In this regard, when it is determined that the ADC voltage has reached within a predetermined range from the threshold voltage (V_th) or the threshold voltage (V_th), a second message generating and outputting process (S150) that outputs “ADC voltage = V_th” is performed. I can.

Meanwhile, although the ADC voltage has not reached within a predetermined range from the threshold voltage V_th or the threshold voltage V_th, it may be determined whether the ADC voltage exceeds the threshold voltage V_th (S130). When it is determined that the ADC voltage exceeds the threshold voltage V_th, a first message generating and outputting process (S140a) for outputting “ADC voltage> V_th” may be performed. On the other hand, if it is determined that the ADC voltage is less than the threshold voltage V_th and has not reached the threshold voltage V_th, a first message generating and outputting process (S140b) for outputting “ADC voltage <V_th” may be performed. .

2A to 6, when the ADC voltage is lower than the lower limit of the certain range or higher than the upper limit of the certain range at the point where the receiver 130 is connected, the ADC voltage deviates from the lower limit or the upper limit. It is possible to generate and output a first message indicating to. In this case, the connection point of the receiving unit 130 means a point where the diode 130a and the resistor 130b are connected. Meanwhile, when the ADC voltage is maintained above the threshold voltage in a certain range for a predetermined time or longer, the controller 300 may generate a second message indicating that the ADC voltage has reached the threshold voltage, and determine that a specific button has been pressed. . Accordingly, the control unit 300 may control the driving unit 410 based on an operation corresponding to a specific button.

Meanwhile, in the present invention, it is possible to precisely control whether or not a specific button is touched by adjusting the number of bits for which the ADC voltage is precisely controlled. Accordingly, it is possible to determine whether a user intended proximity touch input to a specific button and/or an adjacent button or an unintended operation. In this regard, the controller 300 performs analog-to-digital conversion so that the number of bits at which the ADC voltage is precisely controlled is increased when the rate at which the current intensity generated by the sensor 130b is changed through the constant current circuit is equal to or greater than a predetermined ratio. 2 ADC voltage can be detected again. In addition, the controller 300 generates a second message indicating that the second ADC voltage has reached the threshold voltage when the second ADC voltage is maintained above the threshold voltage in a certain range for a predetermined time or longer, and a specific button is pressed. It can be judged as.

In the above, a method of determining a proximity touch input for a specific button related to an elevator operation according to an embodiment of the present invention has been described. Hereinafter, a method of controlling such that an unintended operation of another adjacent button is not detected before a proximity touch to a specific button associated with an elevator operation is recognized according to another embodiment of the present invention will be described.

In this regard, Fig. 7A shows a close/open button and an up/down button of an elevator in connection with the present invention. Meanwhile, FIG. 7B shows numeric buttons corresponding to the floors to which the elevator reaches in relation to the present invention.

7A and 7B, 1) a closing operation may be performed by pressing the closing button once. 2) If you press the open button once, the open operation is performed, and if you keep pressing the open button, the open state is maintained. 3) If the UP button is pressed once, the lifting operation is performed, and if the UP button is kept pressed, the open state can be maintained. 4) If you press the down button once, the descent operation is performed, and if you keep pressing it, the open state can be maintained. 5) If you press the number button once, the elevator moves to the floor corresponding to the number, and if you press it again, the movement to the floor is canceled.

In this regard, 1) elevator buttons have a problem in that when the user presses the desired floor number button (with a finger or an object) because the buttons are adjacent to each other, another floor button is pressed. To solve this problem, 2) If the infrared sensor output is in a low state for 1 second, the infrared sensor output can be turned off immediately after 0.1 second ON (100 ms). Accordingly, it is possible to prevent the button corresponding to the infrared sensor whose output is turned off from being pressed, and also to prevent the button from being pressed from disturbing light. Accordingly, it is possible to prevent other buttons from being pressed during the process of determining whether a specific button has a proximity touch.

Meanwhile, a method for preventing pressing of adjacent buttons adjacent to a specific button of an elevator according to the present invention will be described. In this regard, there is a problem in that other buttons are pressed when the user presses the desired floor number button (by a finger or an object) because buttons are adjacent to the elevator button of the non-contact type. For example, when pressing a button with a finger, the habit and form of pressing a button are different for each person, so that the lower and the side buttons may be pressed. In addition, when there are many people in a narrow elevator space, there is a problem that the user is too close to the button and an unintended button is pressed.

In order to solve this problem, when a hand or an object is brought close to each other at a distance (1-2cm) of the non-contact elevator button, it is necessary to wait for a certain period of time (0.1 second -1 second) without operating the button immediately. In this case, it operates when a specific button is placed close to each other at a nearby distance, and if a number button is pressed for 2 seconds or more, it is determined that a person is nearby and the button is pressed, and the button press recognition process can be initialized. If you press and hold the lower, open, up and down buttons, it operates according to the corresponding button, and after a certain period of time, the initialization process can be performed. In this regard, FIG. 8 shows a flowchart of a method for preventing pressing of an adjacent button in an elevator operating system according to the present invention. Referring to FIG. 8, the method of preventing the adjacent button from being pressed may include a control variable setting process (S210), an infrared output initialization process (S220), and an output time determination process (S230, S240). In addition, the method of preventing pressing of an adjacent button may further include first and second control operation processes S250a and 250b and a depression prevention control operation process S260.

In the control variable setting process (S210), when a sensor output for a specific button is in a LOW state, a CYCLE_TIME value, which is a period for controlling other buttons to be pressed, and a CHECK COUNT value, which is a period for detecting sensor output, may be set. For example, a CYCLE_TIME value = 100ms, a CHECK COUNT value = 10ms may be set, but the present invention is not limited thereto. In the infrared output initialization process (S220), the sensor output for the plurality of buttons may be initialized to be zero. For example, it may be set so that infrared output = 0 (initialization), and infrared output Count = 0 (initialization).

In the process of determining the output time (S230), when the sensor output for a specific button is held in the LOW state for a second predetermined time, for example, 1 second, the other button may be prevented from being pressed (S260). For example, when the CYCLE_TIME value elapses, the control may be performed to prevent the other button from being pressed (S260).

In the process of determining the output time (S240), it may be determined whether the sensor output is kept in the LOW state for a second predetermined time or longer according to the proximity state to the specific button. When the maintenance of the sensor output in the LOW state is less than the second predetermined time, the first control operation process S250a may be performed. In the first control operation process (S250a), a message indicating that the LOW state of the sensor output is 1 second or longer or exceeds is output/transmitted, and the sensor output for a specific button is initialized to 0 (S220), and a specific button is pressed. Whether or not it may be determined again (S230). On the other hand, when the maintenance of the sensor output in the LOW state is less than the second predetermined time, the second control operation process S250b may be performed. In the second control operation process (S250b), a message indicating that the LOW state of the sensor output is less than 1 second is output/transmitted, and the sensor output for a specific button is initialized to be 0 (S220), and whether a specific button is pressed is determined. It can be determined again (S230).

Regarding the above-described technical feature, referring to FIGS. 2A to 8, the controller 300 may perform the following operations. When the sensor output for a specific button is in a LOW state, the controller 300 may set a CYCLE_TIME value, which is a period for controlling other buttons not to be pressed, and a CHECK COUNT value, which is a period for detecting the sensor output. In addition, the controller 300 may initialize so that sensor outputs for a plurality of buttons become 0.

On the other hand, when the proximity state to the specific button is maintained for a second predetermined time less than the predetermined time and the sensor output to the specific button is in the LOW state, the controller 300 may control to prevent other buttons from being pressed. For example, when the sensor output for a specific button is in a LOW state, the controller 300 may control to prevent other buttons from being pressed when the CYCLE_TIME value elapses.

On the other hand, when the sensor output is kept in a LOW state for less than a second predetermined time according to a proximity state to a specific button, the control unit 300 initializes the sensor output to be 0 and whether the specific button is pressed. Can be judged again. On the other hand, if the sensor output is kept in the LOW state for a second predetermined time or longer according to the proximity state to a specific button, the controller 300 may re-determine whether a specific button is pressed while preventing other buttons from being pressed. I can. In this case, when the sensor output exceeds the second predetermined time in the LOW state and the time corresponding to the CHECK COUNT value elapses, the controller 300 initializes the sensor output to 0 for a specific button and presses the specific button. You can judge again whether or not.

Referring to FIGS. 2A to 8, it may be assumed that when the first button and the second button of the plurality of buttons are pressed, the first ultraviolet LED and the second ultraviolet LED are respectively driven. In this regard, when it is determined that the first button is pressed, the controller 300 may perform ultraviolet sterilization and disinfection using the first ultraviolet LED. The control unit 300 may deactivate a process of recognizing an adjacent button during ultraviolet sterilization and disinfection by the first ultraviolet LED. However, when the amount of light of the first UV LED is less than a threshold value during UV sterilization and disinfection by the first UV LED, the control unit 300 can drive the UV LED while deactivating a process of recognizing a button for an adjacent button. Accordingly, when the amount of light of the first UV LED is less than the threshold, the controller 300 may control the UV sterilization and disinfection to be performed in the peripheral area of the first button by driving the third UV LED closest to the first UV LED. .

In addition, when the amount of light of the first ultraviolet LED is less than the threshold value during ultraviolet sterilization and disinfection by the first ultraviolet LED, and a touch operation is received around the fourth button within a predetermined distance from the first button, the controller 300 takes this into account. External sterilization and disinfection can be performed. In this case, the controller 300 drives the fourth ultraviolet LED corresponding to the fourth button when the amount of light of the first ultraviolet LED is less than the threshold value, and a touch operation is received around the fourth button within a predetermined distance from the first button. It is possible to control so that ultraviolet sterilization and disinfection are performed in an area around the first button.

In the above, an elevator operation method using a non-contact type switch according to the present invention and an elevator operation system performing the same have been described. Looking at the technical effects according to the present invention are as follows.

According to the present invention, it is possible to provide an elevator operation method and system for determining that a specific button is selected when a user is adjacent to a non-contact switch for a predetermined time or longer without directly pressing a specific button.

In addition, according to the present invention, it is possible to provide an elevator operation method and system in which only a specific button to be selected by a user is recognized and selection of other adjacent buttons is restricted.

The features and effects of the present invention described above will become more apparent through the following detailed description in connection with the accompanying drawings, and accordingly, those of ordinary skill in the technical field to which the present invention pertains can easily implement the technical idea of the present invention. I will be able to.
