And a group management control device 103 which readjusts the driving mode and controls the driving speed to gradually change when the driving mode is changed to reach a predetermined speed; System status that interfaces with the exhalation control devices 102A-102N and provides load information according to the number of passengers of each exhalation machine 101A-101N, information for checking whether the safety system is abnormal, information related to the driving direction, and the like. An information input unit 104; An operation guide unit 105 for interfacing with the group management control device 103 to output a warning sound when the operation mode of each unit 101A-101N is changed, or to perform a guide broadcast; In the event of a failure, it is configured as a computer terminal 106 for selectively connecting the exhalation control devices 102A-102N from the outside to check the driving history of each of the exhalations 101A-101N.

The exhalation controller (102A) includes an interface unit (111A), (111B) for the interface with the system status information input unit (104), military management control unit (103); A clock generator 112 for providing clock information required by the system; A statistics unit 113 for statistically processing operation related data of the corresponding unit by time zone, day of the week, and traffic characteristics; A database storage unit 114 for storing data statistically processed by the statistics unit 113; A learning unit 115 learning a traffic volume change based on the traffic information of the database storage unit 114 so that the group management control unit 103 determines an optimal driving mode; A direction determination / switching unit 116 for determining and switching a driving direction according to the control of the group management control device 103 or according to a manual operation of an administrator; A driving history backup unit 117 for managing a recent driving history; The group management control device 103 is configured as a group management abnormality determining unit 118 for determining whether the group management control function is normally performed.

The internal configurations of the remaining exhalation control devices 102B-102N and the group management control device 103 are also the same as those of the exhalation control device 102A. However, the group management control device 103 differs from the breath control devices 102B-102N which control its exhalation as the control device 102B-102N. The device 102A differs from the fact that an abnormality has occurred in the group management control device 103 and the function of acting on behalf of the group management function is not normally added, and the exhalation control devices 102B-102N determine the driving direction. The difference is that the function is not provided but only a function for switching according to the military management control.

When described in detail with reference to Figures 3 to 5 attached to the first embodiment of the present invention configured as described above.

Each unit 101A-101N is installed and operated in the adjacent floor, and these are group-managed by the group management control device 103. That is, each of the units 101A-101N is selectively operated by the military management control device 103, and the operation mode such as the driving direction and the speed of the units determined to be operated is also determined by the military management control device 103. do.

The military management control device 103 receives the traffic information of the latest (for example, 5 minutes ago) learned for each of the units 101A-101N, and predicts the traffic volume to be developed in the near future based on the backup information. Based on the result, the number of escalators and the mode of operation are determined.

Each breath control device (102A-102N) is in connection with the group management control device 103 serves to substantially control the operation of the unit, and later the group management control device 103 is the optimal operation mode The change in the traffic volume is to be learned so as to determine, and the operation of the first unit control device 102A as an example will be described in more detail as follows.

When an operation command is issued from the military management control device 103 to the first unit control device 102A through the interface unit 111B, first, the safety system from the system status information input unit 104 through the interface unit 111A. (E.g. overload, sagging fan belt, jamming of abnormal substances, etc.) Check if a signal is input to indicate no abnormality.

If it is determined that there is no abnormality in the safety system as a result of the checking, the driving direction is switched to the up or down direction based on the driving control signal input from the military management control device 103.

Accordingly, the first unit 101A is operated in the set driving mode. At this time, the statistical unit 113 statistically processes the characteristics of the traffic volume by time zone and day of the week using the time information of the clock generator 112 and stores the database. Stored in the section 114.

In addition, the learning unit 115 learns the traffic volume change based on the traffic information of the database storage unit 114 so that the military management control device 103 can determine the optimal driving mode, and the driving history backup unit ( 117 manages recent driving histories to provide convenience in troubleshooting in case of emergency.

On the other hand, the military management control device 103 determines the traffic volume change in the same manner as the first control unit 102A targets the learning result of each control unit 102A-102N operating as described above to each unit Adjust the operation mode for each time zone of (101A-101N).

For example, in a building in which three units 101A-101C are installed on the same floor, the traffic volume of units 1101A and 2B 101B is changed as shown in the table of FIG. A process in which the operation mode of -101C) is adjusted by the military management control device 103 is as follows.

However, if the number of passengers is 1-4, stop the operation of the unit, if 5-15 people operate one unit in the direction, if more than 16 people operate two units in the direction, Unit 1 (101A) is in the ascending direction, Unit 2 (101B) is running in the downward direction, Unit 3 (101C) is operated in the ascending or descending direction in accordance with the traffic volume change of Units 1 and 2 (101A, 101B), The operation time of the change of the operation mode is 10 minutes.

In this case, the second unit 101B stops descending operation from 10:00 to 10:30, and the third unit 101C is in parallel with the first unit 101A in consideration of the concentration of passengers in the first unit 101A. To the up direction. Thereafter, only the first unit 101A runs in the upward direction from 10:30 to 10:40, and only the second unit 101B runs in the downward direction until 10:40 to 11:10. Thereafter, the second unit 101A and the third unit 101C are operated in the upward direction from 11:10 to 11:20, and the first unit 101A is the upward direction from 11:20 to 11:30, and the second unit 101B is in the upward direction. ) Runs in the downward direction, and from Unit 11:30 to 11:40, Unit 1 101A and Unit 3 101C run in the upward direction, and Unit 2 101B run in the downward direction.

As described in the above description, the current driving mode is changed through the driving guide unit 105 for passengers on board or waiting passengers when changing the driving mode of each unit 101A-101N according to the change of traffic volume. Notify performs a guide broadcast, and outputs a warning sound through the buzzer installed around each unit (101A-101N) as necessary. In addition, as described above, when the driving mode is changed, the motor drive inverter is appropriately controlled for the safety of the passengers, and the driving speed is gradually decreased, and when the driving mode is started, the driving speed is gradually increased to reach a certain speed. do. By doing so, the passenger is not embarrassed when the driving mode is changed.

When controlling the operation of the escalator through the above process, when the preset operation end time (business end time) is reached or when the administrator operates the manual operation switch (not shown in the drawing) in the corresponding end mode, all the machines (101A-101N) ) Will be suspended.

For reference, in an escalator using a normal motor, it is impossible to reach a constant speed by gradually increasing the speed, or to stop the vehicle while slowly decelerating and stopping, but in the case of an escalator using a motor of an inverter driving method. This is because the inverter drive type motor can be precisely controlled.

The group management control device 103 performs a switching function such as manual operation, ascending operation, descending operation, stop, etc. in software to set the operation mode as described above.

When a hardware or software failure such as a down of a microcomputer mounted on the group management control device 103 occurs, an exhalation control device having a group management function, for example, the first unit control device 102A performs a group management function. You will act. To this end, the military management control unit 103 checks from time to time whether there is an abnormality in the military management control function through the self-determination unit 319, the military management abnormality determination unit 118 of the unit 1 control unit 102A group management It is determined that an abnormality has occurred when the signal is transmitted to the control device 103 at a predetermined period and is not fed back.

When it is determined that an abnormality has occurred in the group management control device 103, the unit 1 control unit 102A replaces the group management control device 103 with the group management control function for all the units 101A-101N. Act on behalf of. To this end, the first unit control device (102A) is to perform the tasks required for military management in the same way as the usual military management control device (103) to exert a military management control function in case of emergency.

On the other hand, when the user manually operates the manual operation switch respectively installed in each of the machines (101A-101N), the control authority of the military management control device 103 is released, and the corresponding operation is performed according to the operation result of the user. The driving mode is stopped or driven and the driving mode is determined in the ascending and descending directions.

On the other hand, in the system state information input unit 104, each of the air control unit (102A-102N) transmits the various operation information for checking the abnormality of the safety system as described above to each air control unit (102A-102N), The operation information is provided to detect the number of passengers of each unit 101A-101N.

As an example of detecting the number of passengers in each of the air control devices 102A-102N based on the driving information output from the system state information input unit 104, the load of the corresponding air is checked and divided by a predetermined value, Based on the current applied to the drive motor, or as shown in FIG. 4, the riding factor is detected using a pair of optical sensors 402A and 402B provided at one end portion of the handrail 401. FIG. The detected riding parameters are transmitted to the group management controller 103 as necessary.

On the other hand, since the operation history backup units 117, 217, ... of each unit controller 102A-102N manage the operation history of each unit 101A-101N, when a failure occurs, a repair agent externally accesses the computer terminal 106. It is possible to refer to the driving history by connecting with the operation history backup unit of the corresponding machine, so that more rapid and accurate failure recovery is possible.

In the above description, the statistical units 113, 213, ..., and learning units 115, 215, ..., respectively, are installed in the respective air control devices 102A-102N, and the change of the traffic volume of the self-expiratory air is used as an example. In another embodiment, as shown in FIG. 2C, the traffic volume of each unit 102A-102N is analyzed using the statistics unit 113 and the learning unit 115 only in the unit 1 control unit 102A, and the rest of the unit is analyzed. The exhalation control devices 102B-102N may transmit traffic information to the military management control device 103 or the first control device 102A, but do not analyze the traffic volume change on their own.

On the other hand, as a second embodiment of the present invention, the group management control function is to hold only the group management control device 103. In such a case, the first unit controller 102A has the same function as the other unit controllers 102B-102N. Of course, in such a case, the military management abnormality determination unit 118 is unnecessary, and the direction determination / switching unit 116 does not need the direction determination function as in other breath control devices 102B-102N, and has only a switching function. do.

On the other hand, as a third embodiment of the present invention, without using a separate group management control device as shown in FIG. In this case, the unit 1 control unit 102A performs the control function of the self-protecting unit 101A like the other unit control units 102B-102N, as well as the group management control for all units 101A-101N. It will perform the functions together.

As described in detail above, the present invention, by estimating the traffic changes of the escalators of the inverter drive method to perform a predictive driving, or by setting an appropriate driving mode automatically according to the traffic volume that is changed at any time, a separate management personnel There is an effect that can obtain the optimum operating efficiency without. In addition, by managing the operation history to refer to when a failure occurs there is an effect that can respond more quickly and accurately to the occurrence of the failure. In addition, by implementing a military management control function in dual relay has the effect of ensuring the maximum stability of the system. In addition, it is possible to save the cost of the product as much as possible to be used in a certain exhalation controller without having a separate military management control device.
