Abstract

As communication technology is integrated into elevators, hall stations become more and more functioning, and depending on the function of the hall station, the setting details must be checked and confirmed during installation and maintenance work. In order to check various functions one by one, it is inconvenient to check the actual operation state, so it is often impossible to check all of the functions, and to improve the disadvantage that it takes a long time to check one by one. We want to provide a very quick and simple way to do this without any disruption to functionality.

A general elevator control system includes an elevator main controller installed in a machine room and a hall on each floor, a main controller, a hall station connected to a communication line to perform input / output and control of related signals in a hall, and a main controller connected to a communication line. It consists of a button, button lamps and switches on the operation panel, and a car station that controls lights and fans for ventilation.

These elevators are system products of the same size as the building's entire size.In general, 20 ~ 30 floors are installed in apartment buildings with 20 ~ 30 floors, so it is time to check and test hall stations installed on each floor. In addition, due to the problem of not testing the entire I / O function, you can not guarantee the accuracy. If you want to check the setting information such as ID of hall station, loosen the screws on the front panel installed on each floor and turn it over to check the setting, or in the case of the model installed on the wall inside the hoistway, switch the elevator to maintenance operation mode and board the car. It is operated by manual operation inside the hoistway, and after dismantling the cover, check the setting status of the switch for ID and get off again to check the display status, or form a pair of people and set it on the car and check the indicator on the hoistway. However, it is difficult because all functions are not displayed.

In addition, when the test mode is selected in the control panel to test the display unit, there is an example of using the function of rotating and displaying the entire area of the display unit. However, if the watch is watched during the entire driving time in the platform, only the display unit is checked. It is not known whether it works properly, and during the check operation, it is impossible to check the function of the button input unit, and there are inconveniences in that the function is checked only in accordance with the operation of the elevator while traveling several dozen floors in an automatic state.

In order to facilitate the quick and easy switch inspection and confirmation procedures for ID setting of hall stations to be performed by the above complicated procedures, the pursuit of the quickness of maintenance and the convenience of installation work is also performed. Even if it is determined by the setting or operation alone, it simply checks in front of the platform to open the hall station's cover and make correction setting and confirmation only when there is a problem.

In general, the configuration of an elevator control system using communication includes an elevator main controller (1) installed on the top floor or the lowest floor of a building and an upcall button, a downcall button, which are installed on each floor of a building to register a call for ascent and descent. Hall station 2 for controlling the indicator, and the car station (3) for the switch input and buttons of the operation panel, the indicator output is installed inside the car. The hall station 2 and the car station 3 exchange data with the main control panel 1 of the machine room in charge of the operation of the elevator, and transmit the control contents of the buttons and switches installed in the car and hall to the main control panel. It is configured to perform the display and control of transmitting the control contents of the main control panel 1 at each position of the car hall.

In particular, the hall station 2 of the present invention uses an embedded microcontroller 20 having a built-in program memory and an input / output function for control processing as shown in FIG. 2, and the up call button 24 and the down call button 26. ) Up and down registration button lamp 25 to display the input and call registration results of the input and parking switch 29, the down registration button lamp 27 and the position indicator 28 to display the position of the elevator car, the current elevator An additional indicator 28-1 for displaying the operation mode and special functions, and two directions 22 for indicating the driving direction of the car, and two lanterns for indicating the arrival of the car. ), It is composed of a switch 21 that can be set to various values for setting the ID of the floor.

The control processing procedure of the present invention will be described in detail using the hall station configured in FIG. The additional indicator 28-1 of the hall station 2 may display functions such as <inspection>, <emergency operation>, or <a thousand won>, <during moving operation>. During manual operation for inspection, the additional indicator 28-1 is displayed as <inspection> to inform the user that the inspection is in progress and to minimize inconvenience. The present invention provides a test method that greatly reduces the labor cost for inspection as well as the initial installation labor costs by completing the test quickly and simply while testing all the functions by simplifying the inspection function by utilizing these functions. .

As shown in the control flow chart of the present invention of FIG. 3, the elevator is pressed by pressing the up call button 24 and the down call button 26 of a specific floor at the same time while the additional indicator 28-1 is turned on. The hall station 2 installed on the floor on the location display unit 28 displays its own ID already set on the switch 21, and the remaining additional indicator 28-1, the turn signal 22, and the lantern driving port ( 23), the ascending registration button lamp (25), the descending registration button lamp (27) all lights up to check whether there is an abnormality. In this way, if the ID of the corresponding layer is displayed differently, since the setting of the switch 21 is incorrect, the front panel can be dismantled to correct the setting. If the ID of the floor is not displayed on the location indicator 28, or if the additional indicator 28-1, the ascending registration button lamp 25, the descending registration button lamp 27 or the turn signal 22 do not light, If the up-call button 24 and the down-call button 26 are both displayed without being pressed at the same time, the function of the corresponding hall station can be judged as defective. do. If the communication function is not normal, the hall station 2 is not able to display the additional indicator 28-1 of &quot; under check &quot; so that communication errors can be checked at once. When the up / down call button for the test of the hall station 2 is finished, 11 routines of FIG. 3 are executed immediately. Therefore, the lamp and the ID display that are lit to confirm the test contents are changed according to the original command of the main controller. do. The operation of the routine 11 of FIG. 3 indicates that the output displays for checking performed on the right 6 to 10 routines other than the routine 0 of FIG. 3 are cleared are described in detail at the bottom of FIG. All commands and other states are OFF). The original command refers to the command issued through communication from the main control panel of the elevator installed in the machine room, which is the command of 0 routine which is executed in the first part of FIG. Since the test is started in the state of communication by the 0 routine of FIG. 3, there is an advantage that the communication function is naturally tested. The ID in the above description is a value set by the ID setting switch 21 shown in the hall station configuration diagram of FIG. 2, and each hall station is set to an exclusive number in an elevator control system and corresponds to this number. It is used as ID of hall station. In the present invention, it is possible to save a lot of time and effort because it is possible to check the set number by simply pressing the up and down registration button at the same time in the elevator check state without checking the inside of the board installed in this way. In order to increase the effect of the test operation, a technique of increasing the reliability of the inspection may be applied by controlling the entire display LED to be repeatedly turned on and off after displaying the hall ID.

When the function of the hall station 2 is tested in this manner, if the <inspection> additional indicator 28 is not turned on, pressing any of the up and down call buttons 24 and 26 at the same time does nothing other than registering the call. Since it does not have any effect on performing the original function of the hall station (2). In addition, since the call is not registered even when the call button is pressed during the manual operation for inspection, unnecessary driving does not occur due to unnecessary registration of the call.

When testing the hall stations distributed in each floor in a high-rise building elevator function as a function of the present invention can greatly reduce the labor cost of the initial test time. In addition, test results such as confirmation of setting contents of ID, lighting of lamp, light off function and state are also very accurate. The function test work of the hall station can be performed by one person, and the elevator is installed, which is very useful for regular maintenance work during operation.
