In case of an abnormality in the military management system such as the air conditioner, each air controller stops the operation or performs the intensive operation such as hole and even cold cooling, which is very likely to cause extreme traffic congestion, and in the case of large buildings with high traffic volume. Due to this, there is a problem in that physical loss and image damage are large. That is, there is a problem in that the allocation function is ubiquitous in the group management controller, and the above-described problem occurs due to the structure in which the exhalation controller is isolated from the call information and the other breathing information.

Accordingly, an object of the present invention for eliminating the structural causes as described above is to provide a group management apparatus and method of the elevator to be able to perform basic military management even in the abnormal state of the military management controller by mounting a military management function in each exhalation controller In providing.

Another object of the present invention is equipped with a military management function in the exhalation controller and also to share the call information and other unit information through the communication to enable the military management only by the exhalation controller in the event of an abnormal military management controller, military management Extreme traffic congestion that can occur in case of controller abnormality can be prevented, and when the number of units is n, each unit controller has the same group management function, so the secondary group management function by the exhalation controller becomes n relay. The present invention provides an elevator military management apparatus and method for improving reliability.

In order to achieve the above object, the group management method of the elevator of the present invention comprises: a first process of determining an abnormal state of a group management controller; The second process of setting as the controller, and the third process of selecting the other exhalation controller as the master exhalation controller in charge of military management when the abnormality occurs while determining the abnormal state of the master exhalation controller performing the group management function as described above. Is done repeatedly.

As shown in FIG. 3, the group management apparatus of the elevator for performing the method made up of each process, as shown in FIG. 3, is a hall call by a hall button provided through a communication function, an exhalation call of an exhalation controller, and various operating states. The military management control unit 201 that accepts and performs a military management algorithm and periodically receives and maintains the data for military management from the military management control unit 201 while performing military management, the military management control unit 201 In the event of an abnormality, the military management controller 200 composed of a backup military management unit 202 which performs military management on behalf of him, and the military management function to assign and control commands to other units, and also to communicate N exhalation controllers 203a to 203n for enabling mutual data exchange and sharing of calling data, and for periodically updating other call state and various calling data, It consists of a communication line 21 in charge of the communication between the group management controller 200 and the breath controller 203a ~ 203n.

As shown in FIG. 4, the exhalation control mechanism performs communication with the group management controller 200, the other unit controllers 203a to 203n, and the hall buttons 204a to 204n via the communication line 21. As shown in FIG. The communication unit 301 in charge and the command of the self-protection unit collects and transmits to the communication unit 301, and receives a group management control command such as an assignment command of the self-protection unit from the communication unit 301 to control the self-protection unit. And a breath control unit 302 for controlling the speed, door, guide information, etc. of the self-protecting unit, and monitoring the state of the group management controller 200 through the communication unit 301, and the group management function at the time of the group management controller abnormality. Master unit determination unit 305 for determining a unit to perform the operation, and a group management function unit for receiving the function activation command of the master unit determination unit 305 performs a military management function to send the assignment and other military management control commands 303, the hole information, the other unit information, the allocation information, and the like It is mainly composed of a backup unit 304 that provides information necessary for performing a group management function to the exhalation controller 301 by the military management controller abnormality by storing and storing.

Referring to the operation and effects of the present invention described in detail above in detail.

At the time of failure of the group management controller 200, the breath controllers 203a to 203n are in charge of the group management function.

This is possible because there is an idle time for the exhalation controller to perform other tasks while controlling the speed of the exhalation due to the development of performance of an exhalation control microcomputer not shown in each exhalation controller.

The exhalation controller can be divided into two functions, one of which is the role of a master (MASTER) aircraft in charge of military management by activating the military management function 303 of FIG. 4 and the other. The management function 303 is not activated and serves as a slave unit performing only a backup function of information.

Referring to Fig. 4 for the exhalation controller performing the same role as described above, the communication unit 301 is a group management controller 200, hall buttons 204a to 204n, exhalation controllers (through the communication line 21) 203a to 203n).

Then, the breath control unit 302 collects the information of the self-protecting unit and controls the speed, door, guide information, etc. of the self-protecting unit, and receives a military management control command such as an allocation command from the communication unit 301 to the self-protecting unit. The self-controller is controlled and the information of the self-protector is transmitted to the communication unit 301.

At this time, the master unit determination unit 305 monitors the state of the military management controller 200 through the communication unit 301, and when the abnormality of the military management controller 200, the group management unit to perform the group management function that was performed Decide

For example, when an abnormality occurs in the military management controller 200, the master breathing unit determining unit 305 is a function for activating the military management function unit 303 when the unit to which the military management controller 200 belongs is a self-protecting unit. An activation command is issued to the military management function unit 303.

Then, the military management function unit 303 receives a function activation command from the master breath determination unit 305, and transmits a military management function, that is, air allocation and other military management control commands through the communication unit 301, and a backup unit. The 304 updates and stores hall information, other unit information, and allocation information through the communication unit 301.

The updated and stored information is provided to the group management function unit 303 of the exhalation controller at the time of the group management controller 200 and used to perform the group management function.

Here, when the group management controller 200 operates normally, the following description will be made based on FIG.

The activation and deactivation of the communication function will be described conceptually by indicating the contact point of the switch.

When the group management controller 200 operates normally and S1 is turned on, the master breath determination unit 305a or 305b of each breath controller 203a or 203b is the group management function unit 303a or 303b of the self-protecting unit. Deactivate (2a, 2b is off) to block the group management control command from the group management function unit (303a, 303b).

At this time, the breath control unit 302a, 302b receives a control command from the group management control unit 201 to control the self-protecting machine, and sends out the self-protecting machine information.

At this time, the backup unit 304a, 304b updates and stores all the information (calling information, exhalation state information, allocation information) necessary for military management, and all the exhalation controllers 203a, 203n when the military management control unit 201 operates normally. ) Acts as a slave unit.

In addition, when an abnormality occurs in the military management controller 200, the operation thereof will be described with reference to FIG. 6. When an abnormality occurs in the military management controller 200 and S1 is turned off, each breath controller 203a is off. Master breath determination unit (305a, 305b) of 203b) immediately detects this and determines one of the breathing machines currently operating normally as the master breath.

There may be various rules for determining the master breathing machine. For example, a number is assigned to each breath controller to determine the lowest numbered or the highest numbered breathing machine as the master breathing machine.

The master exhalation controller thus determined is assumed to be 203a shown in FIG.

Then, the master breath determination unit 305a of the master breath controller 203a activates the group management function 303a (on 2a, and the group management function unit 303b of the slave breath controller 203b is activated). Do not (2b off).

The group management function unit 303a of the master unit controller 203a thus activated performs a function that the group management control unit 201 performs.

To this end, the data is updated by the backup unit 304a and is analyzed by comprehensively storing all the information (calling, exhaling, state and allocation information of the self-protecting and other units, and allocation information). Processing.

In addition, a method for providing an efficient service to a user is derived, and an optimal operation method is derived.

In addition, the various control commands and assignment commands are sent to the self-protecting machine and the other machine.

The breath control unit of the other breath controller except for the master breath controller 203a receives a group management control command from the group management function unit 303a of the master breath controller 203a, and performs control of the breath controller. The information update of the backup unit is performed in the same manner as described above.

After the master exhalation controller is determined, the master exhalation determination units 305a and 305b monitor the state of the other exhalation controllers and reset one of the normal exhalations to the master exhalation unit when a failure occurs in the exhalation unit operating as the master exhalation unit.

The master breath determination unit of the reset master breathing unit activates the military management function of the self-protecting unit, and the subsequent operation is the same as the operation after the initial setting of the master breathing unit described above.

In case of abnormality of the military management control unit 201, only one unit is operated as a master unit and the other unit is operated as a slave unit.

As described in detail above, the present invention is equipped with a basic group management function to each exhalation controller, and has a communication function to exchange the call information and the state of the elevator with each other to implement a basic group management function even in the event of an abnormal group management controller By doing so, it is possible to prevent extreme traffic congestion, thereby making it more reliable.
