Description

ARD Integrated Type Elevator Control Panel {AUTO RESCUE DEVICE INTEGRATED TYPE ELEVATOR CONTROL PANEL} The present invention relates to an elevator control panel with an integrated ARD, and more specifically, to an elevator control panel with an integrated ARD (Auto Rescue Device) that supplies emergency power when a power outage occurs due to the interruption of commercial power supply, thereby significantly reducing manufacturing and installation costs, ensuring the safety of the installer and convenience of maintenance, and ensuring the driving reliability and safety of the ARD. Generally, elevators are installed in high-rise buildings and used to transport people or cargo to a desired floor while ascending and descending in a vertical direction. Fig. 1 illustrates the configuration of such an elevator. Referring to the drawing, a conventional elevator is composed of a cage (10) placed on an elevator passage (41) and providing a space for passengers to board or cargo to be loaded, a hoisting machine (20) placed in a machine room (42) located at an upper position of the elevator passage (41) and providing an elevator driving force while winding a rope (21) connected to the cage (10), and a control panel (30) placed in the machine room (42) and driving control of the hoisting machine (20) so that the cage (10) ascends and descends toward a set floor. Here, the configuration of a conventional control panel (30) is disclosed in FIG. 2. Referring to the drawing, the conventional control panel (30) is provided with a cabinet (31) having an internal receiving space (32) and a control panel circuit section (33) that is placed in the receiving space (32) and controls the speed and torque of the elevator while driving the hoisting machine (20). Additionally, the interior of the control panel (30) is further equipped with an emergency lighting power supply (34), an emergency intercom power supply (36), and a brake power supply (38) as safety devices for the safety of the occupant. The emergency lighting power supply (34) supplies emergency power charged in the built-in battery (35) to the emergency lighting device provided in the cage (10) in the event of a power outage when the commercial power is cut off, thereby providing emergency lighting inside the cage (10). The emergency intercom power supply (36) supplies emergency power charged in the built-in battery (37) to the intercom device in the event of a power outage, thereby allowing the occupant to make an emergency call. The brake power supply (38) supplies emergency power from the built-in battery (39) to the brake device in the event of manual operation of the cage (10) by an operator, thereby allowing the cage (10) to be manually operated. However, as shown in the drawing, the emergency lighting power supply (34), emergency intercom power supply (36), and brake power supply (38) are each equipped with batteries (35, 37, 39) for supplying emergency power, so the size of the device is inevitably enlarged, and as a result, there was a problem that the accommodation space (32) of the narrow cabinet (31) became even narrower. Meanwhile, due to the strengthening of elevator safety standards, the installation of an ARD (Auto Rescue Device) has been mandatory since 2017. An ARD is a device that automatically moves an elevator to a landing on an adjacent floor using emergency power even if the elevator, which is in normal operation, suddenly stops due to a power outage. To this end, as shown in FIGS. 1 and 2, an ARD (50) is installed in a location close to the control panel (30) within the machine room (42). The ARD (50) is equipped with a battery (52) charged with emergency power and a circuit (53) that supplies the emergency power from the battery (52) to the control panel (30) in the event of a power outage, each inside a housing (51) that is provided separately from the cabinet (31) of the control panel (30). However, as described above, the conventional ARD (50) is manufactured and installed separately from the control panel (30), so manufacturing costs and additional installation costs are unavoidable, and since the heavy battery (52) is mounted inside the enclosure (51), the size of the device is enlarged, and there was a problem that the work process and work time for installing the ARD (50) in the machine room (42) became excessive. In addition, as shown in FIG. 2, a power line (L) is constructed between the ARD (50) and the control panel (30) to supply emergency power from the ARD (50) to the control panel (30). This increases installation costs as installation materials such as terminal blocks and cables are used in the power line (L). Furthermore, as terminal blocks and cables are exposed to the inside of the machine room (42), which is in a harsh environment with a lot of foreign substances such as dust and moisture, failures due to short circuits and disconnections can easily occur, and as a result, there was a problem in that the driving reliability a
