The position calculation unit 211 calculates the position of the car 13 in the hoistway 12 based on the pulse signal received from the encoder 173.

  Specifically, for example, when the car 13 moves up and down from a preset reference position in the hoistway 12, the position calculation unit 211 starts counting pulse signals received from the encoder 173. As the reference position, for example, the stop position of the car 13 when the car 13 stops at the landing 19 on each floor of the building 11 can be set.

  Further, the position calculation unit 211 can obtain the position of the car 13 by calculating the distance from the reference position corresponding to the counted value of the pulse signal. Therefore, the encoder 173 and the position calculation unit 211 function as a position detection unit that detects the position of the car 13.

  The raising / lowering direction detection unit 212 detects the raising / lowering direction of the car 13 based on the time transition of the position of the car 13 obtained from the position calculation unit 211. More specifically, if the position of the car 13 per unit time is high, the ascending / descending direction detection unit 212 detects the rising direction, and if the position of the car 13 per unit time is low, Detect the descent direction.

  The above-described detection of the raising / lowering direction of the car 13 by the raising / lowering direction detection unit 212 is merely an example, and the raising / lowering direction detection unit 212 acquires, for example, a pulse signal from the encoder 173 and uses the polarity of this pulse signal to get on the vehicle. The raising / lowering direction of the car 13 may be determined, or a torque sensor may be provided on the output shaft of the motor 172, and the raising / lowering direction of the car 13 may be obtained based on the torque of the motor 172 obtained from the torque sensor. .

  The pressing determination unit 213 determines that the landing button 192 is pressed when receiving the input signal of the landing button 192, and determines that the landing button 192 is not pressed when the input signal of the landing button 192 is not received. To do. The landing call floor storage unit 214 stores the landing call floor that has received a landing call input from the landing button 192. The landing call floor storage unit 214 is realized by a storage device such as the above-described ROM or HDD.

  The display control unit 215 performs control to display the landing call floor stored in the landing call floor storage unit 214 on the information display 22. In addition, as described with reference to FIG. 3, the display control unit 215 performs control to display the landing call floor stored in the landing call floor storage unit 214 using a blinking and lighting display mode.

  Further, the display control unit 215 is configured to detect the boarding direction detected by the raising / lowering direction detection unit 212 from the position of the car 13 obtained from the position calculation unit 211 among the hall call floors stored in the hall call floor storage unit 214. Control is performed to display only the landing call floor located on the up-and-down direction side of the car 13.

  Next, the display processing of the information display 22 for displaying the landing call floor performed by the control panel 21 having such a configuration will be described in detail based on the flowchart of FIG.

  As shown in FIG. 5, first, the pressing determination unit 213 of the control panel 21 checks whether or not there is an input signal of the landing button 192 and determines whether or not the landing button 192 has been pressed (step (hereinafter referred to as S and S). 501). At this time, if the pressing determination unit 213 determines that the landing button 192 is not pressed (S501 / NO), the process of S501 is repeated.

  In S501, when the pressing determination unit 213 determines that the landing button 192 has been pressed (S501 / YES), the landing call floor that has received the input of the landing call from the landing button 192 is stored in the landing call floor storage unit 214 (S502). ). Therefore, for example, when the landing button 192 installed on the fifth floor landing 19 of the building 11 is pressed, the fifth floor is stored in the landing calling floor storage unit 214 as the landing calling floor.

  Next, the display control unit 215 confirms the calculation result of the position calculation unit 211 and the detection result of the raising / lowering direction detection unit 212, and the landing call floor stored in the landing call floor storage unit 214 is obtained from the position calculation unit 211. It is determined whether or not it is a landing call floor located on the up / down direction side of the car 13 detected by the up / down direction detecting unit 212 with respect to the position of the car 13 (S503).

  As a specific example, when the 5th floor is stored as a landing call floor in the landing call floor storage unit 214, the display control unit 215 determines from the calculation result of the position calculation unit 211 and the detection result of the lifting direction detection unit 212, For example, when it is confirmed that the position of the car 13 is on the third floor and the raising / lowering direction of the car 13 is the ascending direction, it is determined that the landing call floor is located on the raising / lowering side of the car 13 (S503 / YES)

  On the other hand, the display control unit 215 determines that, for example, the position of the car 13 is on the third floor and the ascending / descending direction of the car 13 is a downward direction based on the calculation result of the position calculating unit 211 and the detection result of the raising / lowering direction detecting unit 212. If it is confirmed, it is determined that the landing floor is not located on the up-and-down direction side of the car 13 (S503 / NO).

  In S503, if the display control unit 215 determines that the landing call floor is not located on the raising / lowering direction side of the car 13 (S503 / NO), the display control unit 215 determines that the landing call floor is located on the raising / lowering direction side of the car 13. While the call floor is stored in the landing call floor storage unit 214, the processing from S501 is repeated.

  On the other hand, when the display control unit 215 determines in S503 that the landing call floor is located on the up-and-down direction side of the car 13 (S503 / YES), the display call floor is extracted from the landing call floor storage unit 214 (S504). Then, the extracted landing call floor is set as a lighting target. Subsequently, the display control unit 215 generates a lighting signal for lighting the landing call floor to be lit, and transmits the generated lighting signal to the information display 22 (S505). In the hall call floor display unit 222, the light emitting area 222A corresponding to the hall call floor to be lit is turned on (S506).

  Thereafter, the display control unit 215 deletes the landing call floor to be lit from the landing call floor storage unit 214 (S507). Thereby, it is possible to prevent malfunction in the display processing of the information display 22 by the control panel 21 and to secure the capacity of the storage device such as ROM and HDD of the control panel 21.

  Next, the display control unit 215 confirms the calculation result of the position calculation unit 211 and the input signal of the destination floor button 132B, and whether or not the position of the car 13 is the car call floor or the landing call floor, It is determined whether or not the car 13 has arrived at the stop floor (S508). At this time, if the display control unit 215 determines that the car 13 has not arrived at the stop floor (S508 / NO), the display control unit 215 holds the light emitting area 222A of the landing call floor display unit 222 as it is (S509). ), The process from S508 is repeated.

  On the other hand, if the display control unit 215 determines in S508 that the car 13 has arrived at the stop floor (S508 / YES), if the stop floor is the landing call floor, the display call floor is set as a blinking target. To do. Subsequently, the display control unit 215 generates a flashing signal for flashing the blinking landing call floor, and transmits the generated flashing signal to the information display 22 (S510). In the landing call floor display section 222, the light emitting area 222A corresponding to the blinking landing call floor is blinked (S511).

  Next, the display control unit 215 holds the light emitting area 222A of the landing call floor display unit 222 in a blinking state for a while, and then turns off the light emitting area 222A (S512). By such processing, the display processing of the information display 22 by the control panel 21 according to the present embodiment is completed.
