Description

The present invention relates to an elevator button guidance and a structural technique thereof, and more particularly to an elevator button having both touch-free guidance and touch activation bidirectional functions.

All elevators installed in the building are equipped with a car room for moving up and down between each floor and a landing used for the upper and lower car rooms for passengers as well as being installed on each floor. In addition, the car room is equipped with multiple destination floor buttons for issuing commands to the passengers to go to the floor they want to go to, and commands for passengers to go upstairs or downstairs on the wall near each landing. There is also a call button for issuing.

The types of the destination floor button and the call button described above are currently roughly classified into two types, a pressing type and a touch type. Passengers, whether pressed or touch buttons, could not issue (ie, activate) destination floor or call commands to the car room without pressing these buttons by hand.

However, in the above-mentioned conventional technique, since the surface of the above-mentioned elevator button is always pressed by a large number of passengers with a finger, a large amount of dust and pathogens are attached. The dust and pathogens on these buttons are extremely easily transmitted from the fingers of other passengers to another contact, and have a significant effect on the infection prevention work of the pathogen. Cleaning workers who regularly wipe and clean these destination floor buttons and call buttons are assigned to general buildings, which greatly limits the pathogen infection effect of the buttons.

In addition, there are many photoelectric cells, infrared beam sensors, etc. on the market, and when opening and closing the door, a touch-free format is used to detect whether a person or object is blocking the irradiation point of the beam, and large doors, etc. It controls the opening and closing operation. These beam sensors provide touch-free and sensing-type control methods, but it is difficult to accurately identify the command actions issued by the elevator passengers' fingers in elevator control, or a cleaning worker wipes the buttons to clean them. It was difficult to distinguish the difference from the operation such as doing, and it was difficult to apply it to the button of the elevator, and improvement was awaited.

Therefore, the present inventor considers that the above-mentioned drawbacks can be improved, and as a result of repeated diligent studies, he / she has come up with a proposal of the present invention for effectively improving the above-mentioned problems with a rational design.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiments, and various forms may be adopted as long as they belong to the technical scope of the present disclosure. In addition, the techniques related to elevator buttons according to the following embodiments of the present invention particularly include the touch-free guidance method and button structure of the buttons, all of which are destination floor buttons in the elevator car room and call buttons for landings on each floor. Applicable to.

FIG. 1 is a flowchart showing a touch-free guidance method according to an embodiment of the present invention. Regarding the details of the implementation of the sensing method of the present invention, the following steps S1 to S4 are executed for the shield 60 provided with the button 10 incorporating the distance measuring element 20 and the micro control unit 31 (MCU).
<Step S1: Detection of approaching shield>

In the present invention, a light detection member that projects a beam to the outside is selected as the distance measuring element 20, and the distance measuring element 20 can be arranged inside the button 10 and is an indispensable important member of the button 10 structure. The distance measuring element 20 projects a beam to the outside, and is used to detect and determine whether or not the shield 60 approaching the button 10 intends to activate the button 10 in a touch-free manner. In this embodiment, an example in which the distance measuring element 20 is a laser distance measuring device capable of projecting a laser beam to the outside will be described, but the present invention is not limited thereto. In fact, the distance measuring element 20 may be a photodetecting member capable of projecting a beam such as infrared rays to the outside or a detecting member capable of radiating a radar wave to the outside.

More specifically, the distance measuring element 20 detects the relative distance between the shield 60 appearing in the projection region and the distance measuring element 20 by projecting and recovering the beam or wave, and the relative distance is detected. The target distance is the guidance distance L defined in the present invention (see FIG. 4a). When the distance measuring element 20 is a photodetecting member, the shielding object 60 does not have a shielding action on the beam unless it is a translucent object. The shield 60 at the elevator landing and the elevator hoistway is a finger, a part of the human body, a rag, a pen, a hand tool, or the like. Therefore, when the shield 60 causes a shielding action on the beam projected by the distance measuring element 20 within the guided distance L, it indicates that the shield 60 is close to the button 10, and the distance measuring element 20 is used. Is subsequently executed in step S2 described below. On the other hand, when the shield 60 does not generate a shielding action on the beam within the induction distance L, it indicates that the shield 60 is not close to the button 10, and the distance measuring element 20 continues to monitor. The following step S2 is not executed.

A powerback module 34 is provided in the button 10 shown in FIG. 2, and the elevator control unit 50, which is installed at the elevator hoistway or the central control end and controls the ascent and descent of the elevator, is via a power input line 42. The powerback module 34 is supplied with the required operating power (for example, 24V-DC), and the powerback module 34 is installed in the microcontrol unit 31 after first lowering the operating power (for example, 3V). A digital control program and a distance measuring element 20 are used. Further, the distance measuring element 20 transmits a distance measuring signal to the micro control unit 31. Substantially, the distance measuring element 20 is electrically connected to the micro control unit 31 via an integrated bus circuit 36 (Inter-Integrated Circuit, I2C) and acquires operating power to microcontrol the distance measuring signal. It is transmitted to the unit 31. The powerback module 34 is installed outside the button 10, for example, at an elevator hoistway, a central control end, an elevator control unit 50, or the like. The powerback module 34 is included in the scope of application of the present invention as long as it can step down the electric power of the elevator control unit 50 and drive the microcontrol unit 31 to operate.

FIG. 3 illustrates an implementation structure in which the laser distance measuring device is the distance measuring element 20, and the distance measuring element 20 further incorporates a signal conversion module in addition to the sensing unit 21 used as the projection / light receiving port of the laser beam. There is. The signal conversion module is formed by electrically connecting a sensing circuit 22, a signal conversion circuit 23, and a control circuit 24 in this order. The integrated bus circuit 36 is electrically connected between the control circuit 24 of the distance measuring element 20 and the micro control unit 31.

The sensing unit 21 has a laser projection / light receiving member that is surface-bonded (SMT) to the sensing circuit 22. As a result, when the laser beam projected by the distance measuring element 20 to the outside by the sensing unit 21 is shielded by the shield 60 shown in FIG. 4a, the sensing circuit 22 outputs the analog signal A at the position where the shield 60 is located. After transmitting and converting the analog signal A into a hexadecimal digital signal D (Analog-to-digital converter, A / D) by the signal conversion circuit 23, the hexadecimal digital signal D is controlled by the control circuit 24. By bidirectionally communicating with the integrated bus circuit 36, the micro-control unit 31 controls the reading request and transmission time for the hexadecimal digital signal D, whereby the micro-control unit 31 controls the shielding detected by the distance measuring element 20. Identify the position signal of the object 60.
<Step S2: Judgment of change amount δ of distance of shield>

Immediately after step S1, the microcontrol unit 31 shown in FIG. 2 executes step S2 shown in FIG. 1, that is, it is read whether or not there is a change amount δ of the distance with respect to the induction distance L of the shield 60. Further, referring to FIG. 4a, the guided distance L is displayed in the form of at least one linear orbit in the beam projection region. The quantity of the linear orbit is defined by the mounting quantity of the distance measuring element 20, the projection type (for example, direct radiation or scattering), or the wave divergence type. In this embodiment, when a single laser distance measuring device is used as the distance measuring element 20, the linear trajectory is also single. The guided distance L is generated by connecting a calculated distance L ₁ and a trigger distance L ₂ larger than 0 on each linear orbit in series, and the calculated distance L ₁ is between the shield 60 and the trigger distance L ₂ . The trigger distance L ₂ is located between the calculated distance L ₁ and the sensing unit 21 of the distance measuring element 20, and the calculated distance L ₁ and the trigger distance L ₂ are mutually connected via the trigger node P. Is linked to.

As a result, the control program installed in the micro-control unit 31 is the sum of the calculated distance L ₁ or the calculated distance L ₁ and the trigger distance L ₂ in the calculated distance L 1 or by the time interval difference method within a specific time with respect to the distance measuring element 20. It is instructed to continuously read a plurality of distances at a certain position from the guidance distance L of the shield 60 a plurality of times. At least, a plurality of distances at a position where the shield 60 is located are read a plurality of _times from the calculated distance L1 and used as an effective value for determining the amount of change in the distance by the micro control unit 31. The number of sequential reads is a plurality, and is defined by a control program installed in the micro control unit 31. As a result, when the micro _- control unit 31 determines that the shield 60 has the amount of change δ of the distance within the calculated distance L1, the step S3 described below is subsequently executed. When the micro control unit 31 determines that the change amount δ of the distance of the shield 60 does not change within the calculated distance L1, the process returns to step S1 described above.
<Step S3: Determining whether the amount of change in distance δ is gradually decreasing>

Following step S2, the control program installed in the microcontrol unit 31 shown in FIG. 2 executes step S3 shown in FIG. ₁ , that is, the amount of change in the distance of the shield 60 in the calculated distance L1 δ. Read if it has the property of "gradual shrinking". In the present invention, the "gradual reduction" is defined in the higher technical concept that the amount of change δ of the distance is smaller than the induction distance L and larger than 0, and in the technical concept of the associate level, the said. It is the amount of change δ of the distance that the shield 60 has the characteristic of gradually shrinking generated in the process of gradually moving from the calculated distance L ₁ to the trigger distance L ₂ or the trigger node P, and is the same as the shield 60. It is defined as having an aerial trigger distance L ₂ that is unequal to 0 with the distance measuring element 20 (see FIG. 4a).

＜表一：マイクロコントロールユニットの論理分析数値＞ Specifically, the control program installed in the micro-control unit 31 sequentially records a plurality of valid values at the positions of the shield 60 in the calculated distance L1 at _each time interval difference, and gradually records the plurality of valid values at each time interval difference. Record whether or not there is a change in the distance δ that is reduced to. The amount of change δ of the gradually decreasing distance refers to a situation in which the digital decimal numbers of a plurality of effective numerical values at a certain position of the shield 60 in the calculated distance L1 gradually increase (rectangular frame in Table ₁ below). The part indicated by).

<Table 1: Logical analysis of micro control unit>

In Table 1, in the time stamp (Timestamp) column, it is shown that the micro control unit 31 is operating in a time difference method with a sequential interval of 9.15 milliseconds (ms). In the status column, it is shown that the micro control unit 31 issues a command to read a valid numerical value by performing a request start (Request Start) and a start (Start) a plurality of times to the distance measuring element 20 by the time interval difference method. Further, in the program instruction (RW) column, it is shown that the microcontrol unit 31 sequentially issues a read instruction (Rd) and a write instruction (Wr) to a valid numerical value, and the same address 60 is relatively in the address column. It is shown at the location that the distance measuring element ₂₀ continuously captures the effective numerical value of the position of the shield 60 in the calculated distance L1 and is displayed in hexadecimal in the data column.

Further, referring to the "rectangular frame" part in Table 1, the hexadecimal number "B607" is shown in the data column of the item 1019 column, and "B607" is converted to the decimal number = "1974". Hexadecimal "OC 08" is shown in the data column of item 1021 column, and "OC 08" is converted to decimal = "2060". Hexadecimal "7A 08" is shown in the data column of item 1023, and "7A 08" is converted to decimal = "2170". Since the valid numerical value "1974 <2060 <2170" is gradually increasing, a plurality of distance data of the positions of the shield 60 in the calculated distance L1 have _a change amount δ of the distance gradually reduced. It is determined that the shield 60 intends to trigger the button 10 to control the elevator. At this time, as shown in FIG. 4a, the shield 60 moves toward the sensing unit 21 of the distance measuring element 20 and reaches the position of the trigger node P, and the shield 60 projects / projects the distance measuring element 20. It exhibits a hollow form in which a distance of the trigger distance L ₂ is provided between the light receiving port and the light receiving port. When the calculated distance L ₁ is larger than 0, it means that the existence of a gradually decreasing amount of change δ is allowed, and when the trigger distance L ₂ is larger than 0, the shield is used to prevent the transmission of pathogens. Indicates that the button (eg, finger) does not touch the button 10.

Further, when the effective numerical value after conversion to the hexadecimal number shown in Table 1 gradually decreases or remains unchanged, the distance of the distance gradually reduced to a plurality of distances at _a certain position of the shield 60 in the calculated distance L1. It is shown that the change amount δ does not appear, and the microcontrol unit 31 returns to the above-mentioned step S1 and executes it again. Further, even if the amount of change in the distance that the shield 60 sequentially moves from the trigger node P to the projection / light receiving port of the distance measuring element 20 gradually decreases, the microcontrol unit 31 does not add to the effective value of the amount of change in the distance. ..
<Step S4: Issue a touch-free trigger command to control the elevator>

The button 10 shown in FIG. 2 further includes a trigger circuit 32, an LED guide light 33, and an LED indicator lamp 35. The trigger circuit 32 is electrically connected to the micro-control unit 31 via a circuit board 16, and the micro-control unit 31 can be electrically connected between the distance measuring element 20 and the trigger circuit 32. .. Further, the trigger circuit 32 is further electrically connected to the elevator control unit 50 via a trigger signal transmission line 41 and a trigger signal feedback line 43, and the trigger circuit 32 is further electrically connected to the micro control unit 31 and the elevator control unit 50. It becomes possible to electrically connect to and. The LED guide light 33 is electrically connected to the micro control unit 31 via a circuit board 16, and the LED indicator lamp 35 is electrically connected to the elevator control unit 50 via another trigger signal feedback line 43a. It is connected.

As a result, following step S3, there is a change amount δ of the distance that the micro control unit 31 gradually reduces to a plurality of distances at the positions of the shield 60 in the calculated distance L1, and the button ₁₀ is triggered to trigger the elevator. When it is recognized that there is an intention to control the above, the micro control unit 31 is activated synchronously so as to emit the trigger circuit 32 and the LED guide light 33. The activated trigger circuit 32 issues a touch-free trigger command to the elevator control unit 50 via the trigger signal transmission line 41, and the elevator control unit 50 operates the touch-free trigger command received via the trigger signal feedback line 43. Is returned to the trigger circuit 32, and it is confirmed that the touch-free trigger command has been received. When the LED guide light 33 is a touch-free guide light for the button 10, when the LED guide light 33 is activated and emits light, it indicates to the passenger that the button 10 is detected by the touch-free method. When the LED indicator lamp 35 is used as an indicator lamp indicating the number of floors in the button 10, the elevator control unit 50 is activated to emit the LED indicator lamp 35 at the same time as receiving the trigger command issued by the trigger circuit 32, and the passenger is activated. The elevator displays that the trigger command issued by the passenger has been executed, and heads for the floor where the passenger wants to go. In addition, a buzzer 37 is further provided in the button 10 shown in FIG. 2, and the buzzer 37 is electrically connected to the trigger circuit 32 via a signal line. As a result, when the micro control unit 31 activates the trigger circuit 32, the buzzer 37 is synchronously triggered to sound, indicating that the operation of the trigger command issued to the passenger is completed.

The above-mentioned LED guide lamp 33, LED indicator lamp 35, and buzzer 37 can be selected or implemented together, and all of them are included in the application range of the present invention.

FIG. 5 further illustrates the details of the implementation of the trigger circuit 32, wherein the elevator control unit 50 is electrically connected via a power input line 42 and the operating power required for the trigger circuit 32 (for example, 24V-DC). ) Is being supplied. The trigger circuit 32 is electrically connected to the electronic switch 321 via a pin of the micro control unit 31, and the double contact of the electronic switch 321 is the elevator via the trigger signal transmission line 41 and the trigger signal feedback line 43, respectively. When it is electrically connected to the control unit 50 and the trigger circuit 32 issues a touch-free trigger command, it controls to activate the electronic switch 321 and connects the trigger signal transmission line 41 and the trigger signal return line 43. A touch-free trigger command is issued to the elevator control unit 50 to control the ascent and descent of the elevator. On the contrary, when the trigger circuit 32 does not issue a touch-free trigger command, the electronic switch 321 controls to close the passage between the trigger signal transmission line 41 and the trigger signal feedback line 43.

Next, FIG. 4b describes an exceptional situation in which the shield 60 has not specifically completed steps S1 to S4 shown in FIG. ₁ , that is, the shield 60 moves within the guided distance L1 to measure the distance. When a shielding action is generated on the beam projected by the element 20 (step S1 is completed), but the shielding object 60 moves laterally or only reciprocates laterally in the linear trajectory of the beam (cleaning). Since the worker's operation is simulating the operation of wiping the button with a rag), the amount of change δ of the distance of the linear trajectory of the beam is missing (step S2 is not completed), or the amount of change δ of the distance is present. If the change amount δ of the distance does not include an element in which the change amount δ of the distance gradually decreases (step S3 is incomplete), it is determined that the issuance of the touch-free trigger command is incomplete (step S4 cannot be executed), and the elevator operates. Do not work.
