The present invention relates to a synchronization layer recognition technology of a distributed-controlled elevator, and more particularly, a layer in which itself is located in a hall communication circuit of a corresponding layer through communication between a plurality of hall communication circuits distributed in each floor and a main communication circuit in a control panel. A sync floor recognition method and apparatus for an elevator to recognize a sync floor).

In order to secure efficient operation and reliability of elevators, distributed control systems adopting a distributed control system are gradually increasing. Such distributed control elevators are distributed by arranging hall communication circuits and cage communication circuits on each floor. It is easy to install and maintain. Therefore, the present invention allows the hall communication circuits distributed in each floor to automatically recognize the sync floor during installation and maintenance of the elevator, and to maintain the consistency of all hall communication circuits.

FIG. 1 is a schematic diagram of a sync floor recognition device of a general elevator, and the cage communication units 107 in the hall communication units 104A, 104N, 104T and the cage 106 distributed in each floor as shown therein. The main communication unit 102 for communication, the hall communication unit 104A, 104N, 104T that manages input / output of the hall 100B side and communicates with the main communication unit 102, and the hall communication unit ( The dip switches 105 in the hall communication units 104A, 104N, and 104T, which are used as means for recognizing 104A), 104N, and 104T as the synchronization layer, and the input / output in the cage 107 are managed. And it is composed of the cage communication unit 107 for communicating with the main communication unit 103, the operation thereof will be described as follows.

Hall communication unit 104A, 104N, 104T located in each floor and cage communication unit 107 located in cage 106 and main communication unit 102 located in control panel 101 are composed of a serial network structure. Serial communication is performed between the 102 and the plurality of hall communication units 104A, 104N, 104T.

As described above, in order to perform serial communication with one of the main communication unit 102 and the plurality of hall communication units 104A, 104N, and 104T with the hall communication unit of a specific layer, a unique layer of the corresponding layer capable of recognizing the synchronization layer must be used. A number (e.g., an ID) is required, and for this purpose, the respective dip switches 105 are mounted on the hole communication units 104A, 104N, and 104T, and the dip switches 105 are operated to operate the floor. The identification number (ID) is given to the hall communication unit.

As described above, in the conventional sync floor recognizing apparatus, the installer has to assign an identification number of the corresponding floor by using a dip switch in the hall communication unit for each floor, which makes installation and repair difficult. There is a defect that an error occurs and an unserviceable floor is generated. Also, since the setting state of the dip switch of the hall communication unit is different for each floor, it is difficult to replace or add the hall communication circuit due to the lack of collectiveness of the hall communication unit. .

Accordingly, an object of the present invention is to provide a sync floor recognition method and apparatus for automatically recognizing a sync floor while driving in operation control of an elevator using a contact signal of a hatch door assigned to each floor. .

In order to achieve the above object, a method for recognizing a synchronous floor of an elevator according to the present invention uses an input of a hatch door switch or a hall button assigned to each floor prior to automatic operation after a floor high measurement operation, and inputs an identification number to a hall communication unit of a corresponding floor. An identification call operation process for granting; An identification number re-registration process of assigning an identification number to the hall communication unit of the corresponding floor after moving the elevator to the corresponding floor when the hall communication unit is replaced or added; When the hall communication unit used is replaced with the hall communication unit of another floor, the elevator number is moved to the floor where the identification number is to be changed, and then the identification number changing process is performed to change the culling number of the corresponding hall communication unit.

2 is a schematic diagram of an embodiment of a synchronization floor recognition apparatus of an elevator of the present invention for achieving the above object. As shown therein, the hall communication units 206A, 206N, and 206T are distributed in each floor. And a main communication unit 203 for communicating various types of information necessary for operation with the cage communication unit 209 in the cage 208, and an identification number (ID) from the main communication unit 203 to recognize a synchronization layer, The hall communication unit 206A, 206N, 206T, and the hall communication unit 206A, which are supplied with various operation information required for The hatch door switches SWa, SWn, SWt, and input / output in the cage 208 are used to determine the opening / closing state of the door as a means for the 206N and 206T to recognize the synchronization layer. And a cage communication unit 209 which communicates with the main communication unit 203. One that, when described in detail and the advantages and effects of the present invention constructed as described immediately above FIG. 4 to see the seventh FIG follows.

When the installation of the elevator is completed, as shown in FIG. 4, the floor height measurement operation for identifying the number of operating floors of the building in which the elevator is installed is visualized (S101). In order to cause the hall communication units 206A, 206N, and 206T to recognize the synchronization floor (ID), an identification number (ID) is assigned (S102). (S103)

In addition, as shown in FIG. 5, the last ends of the hatch door switches SWa, SWn, and SWt connected in series to all the layers are connected to the door relay RY in the input / output interface board 204. The hall communication units 206A, 206N, and 206T of the floor determine the open / closed state of the door based on the contact signal of the hatch door switch of the floor.

That is, only the hatch door switch SWn of the Nth floor is substantially operated at the time when the door of the Nth floor is opened, but all of the “high” is supplied to the hall communication units 206N-206T from the Nth floor to the top floor. Only the contact signal of the N layer is input and the contact signal of the N layer or more is ignored. Thus, when there is only one contact point of the hatch door switch, the lower floor number has a higher priority.

Referring to Figure 6 describes the process of the identification number assignment operation mode of the main side as follows.

If the current operation mode is the operation mode for assigning the identification number (ID) by checking whether it is the operation mode for assigning the identification number (ID), it is again checked whether the change mode or the re-registration mode. In this case, the cage 208 is moved to an unregistered layer. (S201-S204)

In this way, when the cage 208 is located in the door zone of the floor to be serviced, the current floor is updated, the operation of the elevator is stopped, the door is opened, and the operation mode is given to the current floor and the identification number (ID). Information is transmitted to the hall communication units 206A, 206N, and 206T. (S205-S207)

Thereafter, after waiting for a predetermined time until the data reception operation from the hall communication units 206A, 206N, and 206T is completed, the received data is analyzed and the identification number (ID) of the current layer is given. The current floor is stored in the memory and registered and the door is closed. However, if the ID of the current floor is not assigned, the door is closed without registering the current floor in memory. (S212-S216)

After that, the elevator is lowered to the lowest floor (S224) and repeats the operation mode for assigning a food punishment number as described above, and when the elevator reaches the lowest floor, it is checked whether all floors to be serviced in the memory are registered. If it is registered, the identification numbering operation mode is canceled and a punishment numbering operation mode release signal is transmitted to the hall communication units 206A, 206N, and 206T. (S218), (S220).

However, if all the layers are not registered in the memory, the re-registration mode is selected (S219) and the elevator is moved to the unregistered layer, and then the fraud process (S205-S207) and (S212-S216) are performed. do. When the re-registration layer is registered in this way, the identification numbering operation mode and the re-registration mode are released, and then the re-registration mode release signal is transmitted to the hall communication units 206A, 206N, and 206T.

When the hall communication board is newly added or when the replacement of the hall board occurs, the identification numbering operation mode and the re-registration mode are selected through the external interface unit 205 to perform the identification numbering operation mode.

In addition, if you want to replace the currently used hall communication board with another hall communication board, select the identification numbering operation mode and the re-registration mode through the external interface unit 205, and the layer to be changed (layer to be changed). ID) in memory to enter ID numbering mode.

On the other hand, if the identification number change mode is selected, that is, if the current mode is found to be the identification number change mode in the operation mode confirmation step (S202), move the elevator to the door zone of the floor to be changed to update the current floor and operate the elevator. Stop the door and open the door (S208-S210), and the main communication unit 203 provides information indicating the identification number (ID) of the change target floor, the current floor, and the identification number change mode in the hall communication unit 206A, 206N, In step S211, transmission is made to step 206T. Then, step S212 to step 216 are performed.

If the identification number change layer is found to be registered by this process (S222), the identification number change mode is released, and the identification number change mode release signal is transmitted to the hall communication units 206A, 206N, and 206T. (S223)

The information transmitted from the main communication unit 203 to the hall communication units 206A, 206N, and 206T in the identification numbering operation mode is common information received by all hall communication units. The identification numbering operation mode and the re-registration mode may be automatically selected by software in the identification numbering operation mode as shown in FIG. 6, and the identification number change mode is transmitted to the input / output interface board 204 through the interface unit 205. FIG. Only by entering the change mode.

On the other hand, with reference to Figure 7 will be described the process for the identification numbering operation mode of the hall side as follows.

In the identification numbering operation mode, the hall communication units 206A, 206N, and 206T receive contact signals of hatch door switches SWa, SWn, and SWt of the corresponding floor to check whether the door is opened. After that, check whether the operation of assigning the identification number is completed. (S301-303)

If the check result indicates that the door is opened and the identification number is not assigned, the current floor received from the main communication unit 203 is stored in the memory and the identification number ID is assigned to the hall communication unit of the corresponding floor. Then, a message informing that the identification number assigning operation is completed is transmitted to the main communication unit 203. (S306), (S307).

When the identification number (ID) is assigned to the hall communication units 206A, 206N, and 206T in this way, when the identification number change mode is set (S304), the change target floor received from the main communication unit 203 is received. Check whether the identification number of is the same as the identification number stored in the hall communication unit (S305) and if the same, the current layer received from the main communication unit 203 is stored in the memory and then the new hole communication unit of the corresponding floor Give an identification number (S305).

On the other hand, Figure 3 shows another embodiment of the synchronization layer recognition apparatus of the present invention, and compared with Figure 2 to recognize that the synchronization layer without using the hatch door switch (SWa), (SWn), (SWt) The use of the hall button 305A, 305N, 305T as a means for different, the operation thereof is as follows.

The process of the operation mode for assigning the identification number of the main side is the same as the signal flow chart of FIG. 6, and the process of the operation mode for assigning the identification number of the hall side is the same as FIG. However, if the hall button of the corresponding floor is turned on in step 302 (S302) of FIG. 7 and the identification number is not assigned to the hall communication units 304A, 304N, and 304T, it is received from the main communication unit 303. It is different from storing the current layer in the memory and assigning an identification number to the hall communication unit of the corresponding layer.

For reference, the input of the hall buttons 305A, 305N, and 305T is forcibly input by the installer.

As described in detail above, the present invention uses the contact signal of the hatch door switch assigned to each floor to automatically recognize the synchronous floor during operation during operation control of the elevator, hall communication board by unifying the hall communication board The beam can be easily replaced or added, and even when the communication board is replaced or added, the hall communication unit recognizes the synchronous floor through automatic operation of the elevator, thereby providing an operational convenience and providing operational convenience.
