The monitor device 4 has a function of displaying the car position, the traveling direction, and the like of the car 1 on the monitor screen.

  Among these, the elevator control device 5 connected to the image control device 3 through the remote monitoring device 6 is installed in a hoistway where the car 1 moves up and down or in a machine room provided separately. By operating the car destination button of the operation panel 1a used by the user (passenger) or the landing button of the hall (both are schematically shown), the hoisting machine shown in the figure is controlled to control the raising / lowering of the car 1, the target floor Various controls related to driving, such as stopping at

  The image control device 3 selects in-car image information and a plurality of image information in accordance with an elevator status signal output from the elevator control device 5 that controls the operation of the car 1 via the remote monitoring device 6. Display on the monitor screen of the monitor device 4. The elevator status signal includes a normal operation status signal that specifies the normal operation of the elevator and a maintenance operation status signal that specifies the maintenance operation when the elevator maintenance work is performed. Therefore, the elevator control device 5 outputs a normal operation state signal to the image control device 3 via the remote monitoring device 6 and instructs the monitor device 4 to display normal operation, and also passes through the remote monitoring device 6. Then, a maintenance operation state signal is output to the image control device 3 and a command for displaying a maintenance operation on the monitor device 4 is issued.

  The remote monitoring device 6 receives an elevator control signal and a failure signal from the elevator control device 5, analyzes the received various signals and detects an abnormality, and if an abnormality is detected, the remote monitoring device 6 passes through the telephone network 9. To the control center 7 installed at a remote location. The control center 7 that has been notified of the abnormality is in charge of contacting the sales office in charge of the maintenance work and instructing the maintenance inspector to be dispatched. Further, the remote monitoring device 6 sends to the image control device 3 the above-described normal operation display command and maintenance operation display command necessary for the image display control transmitted from the elevator control device 5. The monitor device 4 displays in-car image information and a plurality of pieces of image information selected and transmitted from the image control device 3 that has received a normal operation display command or a maintenance operation display command. Image information used by the image control device 3 is accumulated from the control center 7 via the telephone network 9 and the remote monitoring device 6, or from the maintenance portable terminal 8 carried by the elevator maintenance inspector from the operation panel 1a. And stored via the monitor device 4. For this reason, the maintenance portable terminal 8 can be connected to the operation panel 1 a of the car 1.

In the operation processing of the elevator display device, image data to be displayed on the monitor screen of the monitor device 4 by the image control device 3 in accordance with the elevator status signal output from the elevator control device 5 via the remote monitoring device 6. Is to change. More specifically, in the image control device 3, whether or not the elevator maintenance is performed depends on whether a maintenance operation state signal is output from the elevator control device 5 via the remote monitoring device 6 and a maintenance operation display command is received. (Step S01). In this maintenance operation state, a maintenance operation switch (schematic diagram) installed in the operation panel 1a is turned on, or the maintenance portable terminal 8 is connected to a connector (schematic diagram) installed in the operation panel 1a. It is set by performing a predetermined operation, and the setting state is recognized by the elevator control device 5 via the image control device 3 and the remote monitoring device 6.

  Therefore, if the result of the determination is that there is no elevator maintenance (if the normal operation state signal is output from the elevator control device 5 via the remote monitoring device 6 and a normal operation display command is received), the elevator is used by the user. The normal operation display command (step S02) is issued to the monitor device 4 in order to display various image information for the user, and the operation is terminated. If a maintenance operation status signal is output from the control device 5 via the remote monitoring device 6 and a maintenance operation display command is received), maintenance of various control contents corresponding to the maintenance operation status signal required for maintenance inspection work is performed. In order to display information for inspection work, a maintenance operation display command (step S03) is issued to the monitor device 4, and then the operation ends.

  Hereinafter, three different image display examples at the time of normal operation display on the monitor screen of the monitor device 4 that has received the normal operation display command (step S02) shown in FIG. 2 will be described.

  FIG. 3 is a diagram illustrating car image information displayed on the monitor screen 40 during normal operation display of the monitor device 4 included in the elevator display device according to the first embodiment. As for the in-car image information, both a normal operation display command and a door open state signal indicating an open state of the elevator door 1b are input to the image control device 3 from the elevator control device 5 via the remote monitoring device 6. When selected, the image controller 3 selects and designates the image on the monitor screen 40.

  Referring to FIG. 3, the display pattern of the in-car image information includes, as the configuration of the monitor screen 40, a driving direction display unit 41 (indicating the direction of ascending driving) that displays the driving direction of the car 1, A car position display part 42 (indicating that the car is located on the third floor) indicating the current position of the car 1 and a message display part 43 (in this case, “The door opens”) are displayed. An image display unit 44 for displaying a predetermined image (in this case, the actual image information obtained by photographing the inside of the car 1 with the TV camera 2), and a date display unit 45 for displaying the current date and time ( Here, the current date and time is Friday, December 30, 11:28). Among them, the image on the image display unit 44 is received by the image control device 3 via the remote monitoring device 6 from the elevator control device 5 through the stop signal of the car 1 and the door open state signal of the door 1b. Reference numeral 2 denotes real image information obtained by photographing the inside of the car 1 on the monitor screen 40 by the image control device 3. In the display of the in-car image information, the crime prevention effect can be enhanced by notifying the user that the state of the car 1 is being shot and recorded.

  FIG. 4 is a diagram exemplifying caution information displayed on the monitor screen 40 during normal operation display of the monitor device 4 provided in the elevator display device according to the first embodiment. This caution information is obtained when the normal control display command and the deceleration start signal indicating the deceleration start of the car 1 are both input from the elevator control device 5 via the remote monitoring device 6 to the image control device 3. The information is selected from a plurality of pieces of image information by the control device 3 and displayed on the monitor screen 40.

  Referring to FIG. 4, the display pattern of the caution information is the same as that in the case where the configuration of the monitor screen 40 is the display pattern of the in-car video information, and the driving direction display unit 41, the car position display unit 42, the date and time display. Although the contents of the part 45 are the same, the message display part 43 displays a different message “Next is the third floor”, and the image display part 44 displays a different image “Caution when getting on and off. Please be careful. ”Is displayed. Here, as an image of the caution information on the image display unit 44, a warning message to alert the user when getting on and off after stopping is displayed to the users in the car 1. The image display of the caution information indicates the deceleration sent from the elevator control device 5 via the remote monitoring device 6 when the car 1 travels and stops at the destination floor and starts to decelerate before the destination floor. When a deceleration start signal indicating the start is input to the image control device 3, the image control device 3 selects and designates a plurality of pieces of image information and displays them on the monitor screen 40.

  FIG. 5 is a diagram exemplifying presentation information displayed on the monitor screen 40 during normal operation display of the monitor device 4 provided in the elevator display device according to the first embodiment. This presentation information indicates the normal operation display command from the elevator control device 5 via the remote monitoring device 6, and the start of the car 1 from the ground floor entering or leaving the building (building) where the elevator is installed. When both the ground floor travel start signals are input, the image control device 3 selects and designates a plurality of pieces of image information and displays them on the monitor screen 40.

  Referring to FIG. 5, the display pattern of the presentation information is the same as that of the case where the monitor screen 40 is configured to display the in-car video information and the caution information. Is the same, but the car position display section 42 displays the first floor of a different floor, and the message display section 43 displays a message similar to the warning information display pattern “Next is the third floor. Is displayed, and the image display unit 44 displays “Notice Residents' Association. Date and time: December 31 (Sat.) 15: 00-17: 00”. The first floor is usually called the ground floor, and is used for entering and leaving a building, and there are many elevator users. Therefore, when the car 1 starts traveling from the ground floor, for example, when the presentation information for informing the user of the building (building) is displayed, the information of the building is notified to more users of the building (building). Can do. The displayed information is displayed on the ground sent from the elevator control device 5 via the remote monitoring device 6 when the car 1 travels and stops at the destination floor and starts to decelerate before the destination floor. When a ground floor travel start signal indicating the start of traveling of the car 1 from the floor is input to the image control device 3, the image control device 3 selects from a plurality of pieces of image information and displays them on the monitor screen 40. As the presentation information, the elevator maintenance inspection date and time information, the elevator maintenance inspection execution result information, the building (building) water pump due to maintenance inspection of the building (building) water pump, etc. The case where the information which should be made to be displayed can be illustrated.

  FIG. 6 shows in-car video information and a plurality of images for the monitor screen 40 during normal operation display in the monitor device 4 according to the operation pattern of the car 1 by the image control device 3 provided in the elevator display device of the first embodiment. It is a timing chart which illustrated the display pattern which changed and selected information (In addition to the above-mentioned attention information and presentation information, including background image information). That is, here, the elevator controller 5 controls the operation of the car 1 according to the operation pattern in which the car 1 travels from the first floor (ground floor) to the third floor and stops and then travels to the fourth floor and stops. Of the in-car video information and the plurality of image information by the image control device 3 according to the elevator status signal (including the running status signal of the car 1 and the door open status signal) sent from the vehicle via the remote monitoring device 6 The state of switching display is shown.

  Specifically, here, after a user (passenger) first gets in the car 1 on the ground floor, which is the initial stop floor, the third floor is used as a destination floor registration button on the operation panel 1a in the car 1. When the registration button is pressed, the car 1 then goes up to the third floor where the elevator 1 travels through the closing operation of the door 1b and enters the state of departure from the first floor (step S1). At this time, since the image control device 3 receives the door closed state signal and the ground floor travel start signal from the elevator control device 5, the image control device 3 shifts from acceleration to constant speed operation in the ascending travel operation of the car 1, and decelerates. In the meantime, the presentation information as shown in FIG. 5 is first selected and displayed on the image display unit 44 on the monitor screen 40 of the monitor device 4 from a plurality of image information, and then the operation proceeds to constant speed operation After that, the screen of the image display unit 44 is switched to display predetermined background image information (landscape image 1). Here, if the car 1 has reached the vicinity of the second floor in the ascending driving operation, the second floor is displayed on the car position display unit 42.

  As described above, since the user (passenger) frequently enters the car 1 until the car 1 changes from acceleration to constant speed operation and is decelerated, the monitor screen of the monitor device 4 in the car 1 is inevitably generated. Since many people's eyes concentrate on the display content of 40, it is suitable for displaying presentation information related to important news items and the like. The presentation information to be displayed on the screen of the image display unit 44 at this timing is preferably information for a bulletin board user as shown in FIG. 5 for an apartment, for example. It is preferable that it is guide information. Also, when the maintenance inspection side (elevator management side) notifies the maintenance inspection date / time information or the maintenance inspection execution result information, it has traditionally been pasted with a sticker, but this information is used as presentation information. It may be displayed. In any case, the images (presentation information, background image information) displayed on the image display unit 44 in the monitor screen 40 of the monitor device 4 until the car 1 is shifted from acceleration to constant speed operation and decelerated. What is necessary is just to display in order every time it departs from the first floor of the ground floor according to the priority set in consideration of the importance.

  Next, when the car 1 starts to decelerate (step S2), a deceleration start signal for the car 1 is input from the elevator control device 5 to the image control device 3, so that the image control device 3 Until it is stopped at the third floor, which is the destination floor, the attention information as shown in FIG. In this way, even when the car 1 decelerates and stops at the destination floor (third floor), the user's eyes in the car 1 can monitor the monitor screen of the monitor device 4 to confirm the arrival floor. Since the attention information displayed on the screen of the image display unit 44 at such a timing is to get off safely for the user (passenger) in order to concentrate on the display contents at 40, the attention is given to the steps at the landing. It is preferable to include a warning message that calls attention to the content and the opening / closing operation of the door 1b. During the display of the caution information here, the car position display unit 42 displays the third floor because the traveling of the car 1 continues and approaches the third floor of the first destination floor. . Incidentally, a plurality of pieces of image information (presentation) to be displayed on the image display unit 44 on the monitor screen 40 of the monitor device 4 until the car 1 described above changes from acceleration to constant speed operation and is decelerated and stopped. The information, the caution information, and the background screen information) are all configured by a moving image, a still image, a figure, and a character set and registered in advance as described above.

  Further, after the car 1 arrives at the third floor of the destination floor (step S3), a door open state signal indicating the open state of the elevator door 1b is inputted from the elevator control device 5 to the image control device 3, so that the image In the control device 3, the video information in the car by the TV camera 2 as shown in FIG. While stopping on the third floor, that is, after the door 1b of the car 1 is kept open for a predetermined time, the door 1b of the car 1 is closed by the closing operation of the door 1b (step 3). Until S4), the in-car image information is displayed on the image display unit 44, and the display content of the message display unit 43 is erased.

  Subsequently, when the third floor departure (step S4) is reached, the elevator control device 5 again inputs a stop floor travel restart signal that resumes ascending travel from the third floor of the stop floor to the image control device 3. However, since it is not the ground floor travel start signal from the first floor of the ground floor, the bulletin information as shown in FIG. Instead, another background screen information (landscape image 2) is selected from a plurality of pieces of image information and displayed on the image display unit 44 on the monitor screen 40 of the monitor device 4. At this time, “next is the 4th floor” of the message indicating the next destination floor is displayed on the message display section 43. Incidentally, the background screen information that is not highly important may be displayed in a predetermined order or may be displayed at random.

  Further, after the car 1 is started to decelerate (step S5), a deceleration start signal is again input from the elevator control device 5 to the image control device 3, so that the image control device 3 uses the next destination floor of the car 1. In the same manner as described above, attention information is selected and designated from a plurality of pieces of image information and displayed on the image display unit 44 on the monitor screen 40 of the monitor device 4 until it is stopped at the fourth floor. Also here, until the car 1 is stopped on the 4th floor, the destination floor (4th floor) is close, so there is a reminder of the content that calls attention to the steps at the landing and the content that calls attention to the opening and closing operation of the door 1b. It is preferable to display the caution information including the message on the image display unit 44. Incidentally, while the attention information is displayed here, the car 1 continues to move up and approaches the fourth floor of the next destination floor, so the car position display section 42 displays the fourth floor.

  Further, after the car 1 arrives on the fourth floor of the next destination floor (step S6), a door open state signal is input from the elevator control device 5 to the image control device 3, so that the image control device 3 The video information in the car by the TV camera 2 is switched and displayed on the image display unit 44 on the monitor screen 40, and the car 1 is stopped on the fourth floor of the destination floor, that is, the car by the opening operation of the door 1b. After the first door 1b is kept open for a predetermined time, the image in the car 44 is displayed on the image display unit 44 until the door 1b of the car 1 is closed due to the closing operation of the car 1 until the fourth floor starts. Information is displayed and the display content of the message display unit 43 is erased.

  Hereinafter, an image display example at the time of maintenance operation display on the monitor screen of the monitor device 4 that has received the maintenance operation display command (step S03) illustrated in FIG. 2 will be described.

  FIG. 7 is a diagram exemplifying maintenance inspection work information displayed on the monitor screen 40 when the maintenance operation of the monitor device 4 included in the elevator display device according to the first embodiment is displayed. The information for the maintenance inspection work is obtained when an instruction for maintenance operation display and a maintenance operation state signal indicating the maintenance operation state of the elevator are both input from the elevator control device 5 via the remote monitoring device 6. 3 is selected and specified from a plurality of pieces of image information in accordance with the maintenance operation state signal and displayed on the monitor screen 40. That is, when the image control device 3 receives the maintenance operation state signal output from the elevator control device 5 via the remote monitoring device 6, the image control device 3 provides a plurality of pieces of information for maintenance inspection work of various control contents according to the maintenance operation state signal. Are selected from the image information and displayed on the monitor screen 40.

  Referring to FIG. 7, the display pattern of the information for the maintenance inspection work is the driving direction in which the car 1 is raised and lowered as compared with the display examples when the monitor screen 40 has the normal operation display described with reference to FIGS. 3 to 5. Driving direction display unit 41 (in this case, the bidirectional operation of the ascending operation direction and the descent operation direction in a state in which no direction is specified is shown) and the car indicating the floor position in the immediate vicinity of the car 1 A position display unit 42 (indicating that the third floor is the closest floor position here) and a date display unit 45 that displays the current date and time (again, the current date is Friday, December 30, 11: 28).

  In addition, since the display pattern of information for maintenance inspection work is provided to the maintenance inspection worker, the configuration of the monitor screen 40 does not partition the message display section 43 and the image display section 44, but instead, A step display portion 46 for displaying the level difference between the car floor and the car floor (in this case, the car floor does not reach -20 mm from the nearest floor), and the door 1b of the car 1 is opened. On-off display 47 for the door open zone detection switch for detection (indicating that it corresponds to a black circle mark when turned on and not a white circle mark when turned off), and the traveling operation of the car 1 On / off display section 48 (in this case, the upper terminal switch and the upper limit switch are off) for the upper operation limit switch (including the upper terminal switch, the upper limit switch, and the upper deceleration switch) for limiting It corresponds to a white circle, indicating that it corresponds to a black circle when the upper deceleration switch is on), and a descent operation limit switch (lower end switch, descent limit switch, And a downward deceleration switch) for on / off display 49 (indicating that this corresponds to a white circle when various switches are off), and a load ratio display 50 for displaying the load ratio of the car 1 (This indicates that the current load capacity is 13% of the maximum allowable value.) When the door 1b of the car 1 and the door opening / closing operation of the landing door open / close operation instruction and state detection switch (door open) Command, door open end switch, door close command, door close end switch, landing door switch, and car door switch) ON / OFF display section 51 (in this case the door open command and door open end switch are OFF) Open circles correspond to indicia case, door close command has door closed switch, Noribato switches, and and indicate that the car door switch corresponds to the black circle in the case of on), the. The maintenance checker can efficiently perform the maintenance check work by referring to the display pattern of the information for the maintenance check work on the monitor screen 40 of the monitor device 4 in the car 1.

  FIG. 8 is a flowchart illustrating an operation process of display control on the monitor screen 40 of the monitor device 4 during normal operation display by the image control device 3 provided in the elevator display device according to the first embodiment. In this display control operation process, first, the image control device 3 is traveling in the car depending on whether or not it has received a travel state signal of the car 1 from the elevator control device 5 via the remote monitoring device 6. Is determined (step S11). If the result of this determination is that the vehicle is traveling, whether or not the image control device 3 has subsequently received a deceleration start signal from the elevator control device 5 based on the traveling state signal via the remote monitoring device 6. Thus, it is determined whether or not the car is decelerating (step S12). If the result of this determination is that the car is not decelerating, whether or not the image control device 3 has subsequently received an acceleration start signal from the elevator control device 5 based on the running state signal via the remote monitoring device 6. Thus, it is determined whether or not the car is accelerating (step S13). If the result of this determination is that the car is not accelerating, the image update timer built in the image control device 3 is subsequently checked to determine whether or not a fixed time has elapsed since the image update (step S15). As a result of this determination, if the predetermined time has not elapsed, the process returns to the determination (step S11) whether or not the vehicle is traveling for the first time, and the subsequent processing is repeated. If the predetermined time has elapsed, For example, after processing of image update (step S17) for displaying background image information (landscape image 1) corresponding to the constant speed before the start of deceleration (step S2) in FIG. 6, measurement is started by the image update timer (step After S20), the process returns to the determination before whether or not the first car is running (step S11), and the subsequent processing is repeated.

  If it is determined that the car is accelerating (step S13), if the car is accelerating, it is subsequently determined whether the image update timer is measuring (step S14). Do. If the result of this determination is that measurement is being performed by the image update timer, the above-described image update timer is checked, and the process proceeds to determination (step S15) whether or not a fixed time has elapsed since the image update. If it is not measured by the image update timer, the image control device 3 continues from the first floor, which is the ground floor, based on the running state signal from the elevator control device 5 via the remote monitoring device 6. It is determined whether or not the vehicle has started to travel from the ground floor (step S16) depending on whether or not a floor travel start signal has been received (the car position signal indicates the departure floor within a certain time during acceleration). . If the result of this determination is that the vehicle has started running from the ground floor, the image update timer (step S18) for displaying the presentation information as shown in FIG. ), The process returns to before determining whether or not the vehicle is traveling for the first time (step S11), and the subsequent processing is repeated. If the vehicle does not start traveling from the ground floor, for example, the deceleration start ( Step S5) After performing the image update process (Step S19) for displaying the background image information (landscape image 2) corresponding to the transition from the previous acceleration to the constant speed, the image update timer starts the measurement (Step S20). It returns before the determination (step S11) of whether it is the first car traveling, and the subsequent processing is repeated.

  Further, as a result of the determination whether or not the car is decelerating (step S12), if the car is decelerating, the image is updated to display the caution information as shown in FIG. 4 (step S21). After the above process is performed, the measurement is stopped by the image update timer (step S22), and then the process returns to before the determination (step S11) whether or not the car is traveling for the first time, and the subsequent processes are repeated.

  In addition, as a result of the determination whether or not the vehicle is traveling for the first time (step S11), if the vehicle is not traveling, the image control device 3 continues from the elevator control device 5 via the remote monitoring device 6. Determination of whether or not the car door switch signal is OFF (the car door switch signal is OFF from the start of the open state of the door 1b of the car 1 to immediately before the end) based on the running state signals Step S30) is performed. If the car door switch signal is OFF as a result of this determination, the car image display (step S31) for displaying the car video information as shown in FIG. 3 is performed, and then the measurement is stopped by the image update timer. After step (S22), the process returns to before determining whether or not the car is traveling for the first time (step S11), and the subsequent processing is repeated.
