Preferably, the cage 14 may be formed in the shape of a rectangular parallelepiped having an opening and closing door at one side and a space in which cargo is loaded.

At this time, each cage 14 may be guided to be moved along the outer wall of the building 2 by a transfer rail 12 extending in the vertical direction on the outer wall of the building (2).

At this time, each cage 14 may further include a position measuring device. The position meter may measure the current position of the cage 14 and the moving direction.

Specifically, when the cage 14 is stopped on a particular floor, it may contain information about that floor, and when the cage 14 is moving from one floor to another, it contains information between the floor and the floor. can do.

In one embodiment of the present invention, each of the plurality of cages 14 may further include an operation panel therein. The operation panel is capable of manual operation of the cage 14 on which the occupant is occupied, and an identification number switch of the floor to be moved may be formed. In addition, a switching switch for switching between the automatic mode which is operated by the controller 30 to be described later and the manual mode which the passenger manually operates may be formed.

Therefore, when the occupant determines that the load capacity is not sufficient in consideration of the free space of the cage 14, the passenger can be switched to manual operation and separated from the automatic mode by the controller 30. At this time, the cage 14 in the manual mode may not stop on other floors except the floor selected by the occupant.

In addition, a movement switch may be further formed on the operation panel. The transfer switch can be operated by the internal occupant for safety reasons. Lift device group control system 1 according to an embodiment of the present invention may further include a semi-automatic mode in addition to the manual mode and automatic mode. In the semi-automatic mode, the cage 14 is basically determined by the control unit 30, but can be moved only when the movement switch is operated by the internal occupant.

In addition, a call reject switch may be further formed on the operation panel. The call rejection switch may transmit a call rejection signal to the radio reception module of the receiver 32 through the first radio transmission module 16. In addition, the controller 30 may recognize the call rejection signal and determine the priority cage, and may determine the cage 14 that has transmitted the call rejection signal in the priority cage determination process.

At this time, the call reject switch may be operated by the occupant in the cage 14, preferably when the additional boarding space of the cage 14 is insufficient, or the load of the cage 14 reaches a critical load. Can work on.

The current position and movement direction of the cage 14 may be transmitted to the wireless receiving module of the receiving unit 32 by the wireless transmitting module for each cage 14. At this time, the signal transmission means is not necessarily limited to wireless, wired transmission may be possible depending on the installation environment.

The first wireless transmission module 16 may transmit the position information and the movement direction information of the cage 14 received from the position measurer of the cage 14 to the receiver 32. The transmission scheme of the first wireless transmission module 16 may be applied without limitation, such as WIFI, RF, or Bluetooth, but may be appropriately determined in consideration of limitations depending on the transmission / reception distance with the receiver 32. At this time, it may further include a wireless repeater 42 according to the transmission and reception distance.

At this time, each of the plurality of cages 14 may be provided with a space in which the cargo is loaded or a person can ride. At this time, the load measuring device may be formed on the inner lower side of the cage 14.

The load meter may be located at the bottom side of the cage 14, in particular between the cage 14 and the drive. Through this, the load applied by the cargo and the person inside the cage 14 can be easily measured.

In this case, the load information measured through the load measuring device may be transmitted to the receiving unit 32 through the first wireless transmission module 16 in the additionally provided opbox controller. In addition, the load information of each cage 14 transmitted to the receiver 32 may determine whether the critical load has been reached by the controller 30. In one example, the critical load may be 90% of the maximum load.

If some of the cages 14 have reached the critical load, some of the cages may be excluded in the process of determining the senior cage of the controller 30.

In one embodiment of the present invention, the driving unit may further include a motor to drive the cage 14 of the transfer unit 10 in the vertical direction.

In one embodiment of the invention, it may include a caller 20 installed on each floor to call the cage 14.

In this case, the caller 20 may be installed in each floor, as shown in FIGS. 1 and 2. The caller 20 may include a pager 22 and a display device 24.

The pager 22 may generate identification information of the floor where the pager 22 is installed and identification information of the floor to be moved. In this case, the identification information of the floor on which the pager 22 is installed may mean a starting floor for calling the cage 14, and the identification information of the floor to be moved may mean an arrival floor to which the cage 14 should move next.

In this case, the pager 22 may further include a second wireless transmission module 23. The second wireless transmission module 23 may transmit the departure floor information and the arrival floor information to the wireless reception module of the receiver 32. The transmission method of the second wireless transmission module 23 may be applied without limitation, such as WIFI, RF, or Bluetooth, but may be appropriately determined in consideration of restrictions on the transmission / reception distance with the receiver 32.

In one embodiment of the present invention, it may further include a wireless repeater 42 disposed between the first and second wireless transmission module 16, 23 and the wireless reception module of the receiver 32. Thereby, the information can be stably received from the pager 22 located in the higher floor or the cage 14 moved to the higher floor.

The caller 20 may further include a display device 24. The display device 24 can display the cage identification number arriving at the called floor. As will be described later, the priority cage determined by the control unit 30 is displayed, and the person who wants to board may view the displayed information and move to the arriving priority cage.

In one embodiment of the invention, the receiving unit 32 is provided with a wireless receiving module, the wireless receiving module receives the cage 14 position information from the first wireless transmitting module 16 of the transfer unit 10, the pager ( The identification information of the departure layer and the arrival layer may be received from the second wireless transmission module 23 of FIG.

In this case, the wireless reception module may be applied in a manner that is compatible with the first and second wireless transmission modules 16 and 23 described above.

Hereinafter, the control unit 30 of the lift device group control system 1 according to an embodiment of the present invention will be described. The controller 30 may perform various determination processes to drive the cage most efficiently in the lift apparatus having the plurality of cages 14.

In the present specification, the priority cage refers to a cage 14 that responds to a call according to a call signal of the caller 20, and is moved by the controller 30 for efficient control of the plurality of cages 14. It means the cage judged to be the most efficient.

First, the controller 30 may determine the priority cage based on the departure layer information of the pager 22 received by the receiver 32.

When the receiver 32 receives the call signal from the second wireless transmission module 23 of the pager 22 installed on each floor, the controller 30 stores the floor information where the pager 22 that has transmitted the call signal is located. Can be stored in In addition, the direction in which the cage 14 should move based on the departure and arrival floor information may be determined and stored in the memory. That is, when the second and fifth layers are received, it can be determined upward.

In addition, when the receiver 32 receives the current position and the movement direction information of each cage 14 from the first wireless transmission module 16 of the transfer unit 10, the current position and the movement direction information for each cage 14. Can be stored in memory.

At this time, the controller 30 may store in the memory a cage closest to the called starting layer based on the received floor information and the current position information of each cage 14.

The controller 30 may match the movement direction information of each cage 14 based on a close cage order stored in the memory. In this case, any one of up, down and stop variables may be generated.

Thus, the movement direction can be aligned in the closest order among the cages that coincide, then in the closest order among the cages stopped after that, and finally in the closest order among the cages moving in the opposite direction. The cages 14 thus sorted may be ranked in the above order and stored in the memory.

Thereafter, the controller may search for the cage 14 matching the moving direction previously stored in the memory. In this case, the searching order may be a close order previously stored in the memory. If there is no matching cage, it can search for a stationary cage and finally find a cage that moves in the opposite direction.

This makes it possible to determine a cage that has a matching direction of movement among the cages closest to the called floor.

In one embodiment of the present invention, the controller 30 may determine the priority cage in consideration of the available load of the cage 14. For example, as described above, when the priority cage is selected based only on the location information, there may be a problem in that the selected priority cage does not have enough volume space or has already reached the critical load so that no further boarding is possible.

In order to prevent the above problem, the control unit 30 of the lift device group control system 1 according to an embodiment of the present invention may further perform a secondary determination process.

First, when the current load of each cage 14 reaches a preset threshold load, the controller 30 may exclude the cage from the prior cage determination process. Alternatively, if the cage that has reached the critical load is determined to be a priority cage, the next priority cage can be assigned to the called floor.

In this case, a criterion for determining whether the load has reached the critical load may be determined based on load information transmitted from a load measuring device installed in the cage 14, as described above.

In detail, the control unit 30 stores the load information of the cargo to be loaded from the second wireless transmission module 23 in the memory when the reception unit 32 receives the load information from each cage 14 from the first wireless transmission module 16. When load information of) is received, it can be stored in memory.

At this time, the controller 30 may compare the load information to be loaded with the available load information of the priority cage primarily determined by the position information among the available load information of each cage 14.

If the available load of the primarily determined priority cage is large compared to the load of the cargo to be received received from the pager 22 of each floor, it is determined that the primarily determined priority cage has sufficient loading capacity, and thus the previously determined priority The cage can be kept as a senior cage.

If the available load of the primarily determined priority cage is small compared to the load of the cargo to be received received from the pager 22 of each floor, it may be determined that the priority cage does not have sufficient loading capacity.

Therefore, in this case, the next-order cage can be selected among the cage 14 alignment data previously stored in the memory. Thereafter, similarly, the selected next cage may be compared with the load information of the cargo to be loaded using the available load information described above.

Alternatively, if it is determined that the primarily determined priority cage does not have sufficient load capacity, the priority cage may be determined again among the remaining cages except for the above priority cage.

In this case, since the cages 14 may be changed in real time, the cages may be re-received to determine the priority cage first and determine the loading capacity.

In addition, when a call rejection signal is generated in the priority cage primarily determined based on the location information, the controller 30 may reflect this, and may again determine the priority cage among the remaining cages except for the priority cage. Alternatively, the next order cage may be selected from the cage 14 alignment data stored in the memory.

3, a lift device group control system 1 according to another embodiment of the present invention will be described. Descriptions that overlap with the above description will be omitted.

3 is a flow chart of a lift device group control system according to another embodiment of the invention.

In another embodiment of the present invention, the control unit 30 may further include a simultaneous control mode. In the simultaneous control mode, two or more cages of the plurality of cages 14 are simultaneously controlled. Specifically, the call unit 20 may be implemented by calling two or more cages and synchronizing movement of the two or more cages.

This may be useful when there are too many people to board, the volume or load of the cargo to be loaded is too large, and the cargo may be subdivided.

In another embodiment of the present invention, the pager 22 of the caller 20 may further include a simultaneous control switch. The simultaneous control switch can be activated by the boarding waiter and can call more than one cage. The simultaneous control switch actuated by the boarding waiter receives the simultaneous control command and the number of cages 14 to call and information about the starting and arrival floors from which the cages 14 are called via the second wireless transmission module 23. 32 can be sent.

In this case, when the receiver 32 receives the simultaneous control command, the controller 30 may perform the simultaneous control mode.

First, the controller 30 may determine a cage for allocating to the starting layer based on the position information and the movement direction information of each cage 14 received from the first wireless transmission module 16. At this time, When the call reject signal is generated from the cage, the priority cage may be determined from the remaining cages except for the call reject cage.

In simultaneous control mode, the senior cage may include two or more cages called simultaneously.

First, the control unit 30 may arrange cages in which the moving directions coincide among the remaining cages except the call rejection cage in a close order. In this case, the coincidence of the moving direction means that the direction in which the current cage moves is identical between the departure floor and the arrival floor called by the boarding waiter.

After aligning the cages in which the moving directions coincide, the stopped cages can then be sorted in close order, and finally the cages that are moving in the opposite direction can be aligned in close order. These sorted cages can be ranked and stored in memory.

In determining the priority cage in the simultaneous control mode, preferably, the cage 14 which stops between the starting layer and the arrival floor among the cages 14 having the same moving direction may be determined as the lower priority cage.

The lift device group control system 1 according to another embodiment of the present invention may further include a scanning device 26 and a volume meter.

The scanning device 26 may be provided in the calling unit 20 so as to scan the cage 14 and the volume of the occupant calling. In addition, the volume measuring device may be installed on the upper side of the cage 14 to measure a space occupied by the occupant and the loaded object occupied in the cage 14.

The volume measured by the scanning device 26 and the volume meter may be transmitted to the receiver 32 through the second wireless transmission module 23 and the first wireless transmission module 16, respectively.

The controller 30 may reflect the priority cage determination based on the received value. That is, even when a call reject signal is received from the cage 14 or the critical load is not reached, the cage may be excluded from the prior cage determination process when the available volume is small except for the cage internal volume measured by the volume meter. .

In another embodiment of the present invention, the volumetric meter may be implemented in various ways, but may preferably use a method of measuring the area occupied by the cargo or person in the volumetric meter located on the upper side of the cage. Similarly, the scanning device 26 may be located on the upper side of the space where the occupant waits for the cage 14.

For example, when the volume measuring device is a visual sensor using a camera or the like, it is possible to easily measure the area occupied by the cargo or person currently in the cage 14. Alternatively, when the ultrasonic sensor is used, the shape of the reflected ultrasonic wave may be measured, or the approximate space occupancy may be measured through the arrival time of the reflected wave.

According to the exemplary embodiment of the present invention described above, in the lift apparatus having a plurality of cages 14, efficient cage allocation for each floor is possible based on the position information of each cage 14 in terms of time and cost. It can be economical. In addition, in consideration of the loading capacity of each cage 14, unnecessary stops can be reduced, resulting in economical safety.

Although one embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments set forth herein, and those skilled in the art who understand the spirit of the present invention, within the scope of the same idea, the addition of components Other embodiments may be easily proposed by changing, deleting, adding, and the like, but this will also fall within the spirit of the present invention.
