It has a drive motor for raising and lowering the light fixture.

A technique related to the configuration of unwinding and winding a wire rope in an automatic lifting device for a high place lighting or the like is disclosed in Patent Document 1, for example. As the layer of the wire rope wound around the drum increases, the high place lighting lifting device of Patent Document 1 is pushed to the outside of the drum, and when the detection plate is pushed to the set position, the drum is pressed by contact with the sensing plate. It includes a drive switch for stopping the operation of the rotating drive means, and discloses a structure in which the drum is arranged to be placed in an erect state in the main body.

However, according to the prior art, if a breaker goes down due to a power abnormality such as a short occurring in a specific high place light among a plurality of high place lights installed in a facility, even if the electricity is restored by raising the breaker, the corresponding high place light is in a short state.

Immediately after the breaker 301 is turned off, the control unit 300a provided in the microcomputer 300 checks whether or not there is a power abnormality in the corresponding high place installation device 10 and stores the power abnormality information in the memory 300b. In addition, the control unit 300a of the microcomputer 300 checks the power abnormality information of the aerial installation device 10 stored in the memory 300b when the circuit breaker 301 is turned on again, and the power abnormality information For the aerial installation device 10 in which is stored, the relay 304 is turned off to cut off the power supply, and at the same time, the relay ( 304)) is turned on to perform control to supply power. That is, the aerial installation device 10 in which a power abnormality such as an overcurrent due to an overvoltage or short circuit among the plurality of aerial installation devices 10 is generated, the relay 304 is turned off by the corresponding micom 300. Power is cut off and power is supplied to the aerial installation device 10 in which the power abnormality has not occurred, the relay 304 is turned on by the microcomputer 300 to be supplied with power.

As power is supplied to the aerial installation device 10, the aerial installation device 10 enters a standby state for operation. In the standby state for operation, when the high place installation device 10 corresponds to a lighting lamp, the lighting lamp is turned on when the administrator manipulates a switch to turn on the high place installation device 10 using a remote control (see 11 in FIG. 7) or the like.

A capacitor 303 capable of supplying emergency power to the microcomputer 300 for a predetermined period of time, for example, about 1 to 2 seconds, is connected to the micom 300 immediately after the circuit breaker 301 is turned off. Accordingly, the micom 300 may perform an operation of checking whether the high place installation device 10 has a power abnormality immediately after the circuit breaker 301 is turned off and storing the state information in the memory 300b.

Here, it is preferable that the power abnormality detection unit 302 employs a voltage sensor or a current sensor.

The circuit breaker 301 is a device that opens and closes the power system, and is automatically turned off when a short occurs to cut off the power supplied to the plurality of aerial installation devices 10 connected thereto. The circuit breaker 301 may be arranged to collectively open and close the power to all of the plurality of high place installation devices 10 installed in a predetermined facility, and the high place installation devices 10 are set by a predetermined number (for example, around 10). They can also be grouped and arranged in groups.

3 to 5 illustrate a process in which a method for controlling a smart height installation device lifting device according to a preferred embodiment of the present invention is performed.

First, referring to FIG. 3, when the breaker 301 is turned on and the power is turned on, the micom 300 is booted and activated, and a relay 304 that turns on the power by the driving control of the micom 300. ) Is operated to supply power to the aerial installation device 10 corresponding to the microcomputer 300 (steps S100 to S102).

Thereafter, when a short circuit occurs in the specific equipment, that is, the high place installation device 10 due to a predetermined factor, the circuit breaker 301 is automatically turned off (steps S103 and S104).

Immediately after the circuit breaker 301 is turned off, the microcomputer 300 operates by the emergency power of the capacitor 303 to detect and recognize the power off state and overcurrent due to a short circuit, and transmit the state information to the memory 300b. Save (steps S105 and S106). Here, the power abnormality detection unit 302 is composed of a current sensor. The microcomputer 300 receives an overcurrent detection signal from the power abnormality detection unit 302 and recognizes that a power abnormality has occurred due to a short circuit in the aerial installation device 10 corresponding thereto.

After the breaker 301 is turned off, if the breaker 301 is turned on again and the power is turned on again, the microcomputer 300 is booted and the status information about the short-circuit stored in the memory 300b is checked, and the corresponding high place installation device 10 ) To perform drive control on the relay 304 connected to (steps S108 and S109). For example, when information indicating that a power abnormality (overcurrent) has occurred due to a short circuit in the high place installation device 10 is stored in the memory 300b, the microcomputer 300 blocks the operation of the relay 304 It blocks the supply of power to the high place installation device (10). Accordingly, the circuit breaker 301 is normally supplied with power to the high place installation devices 10 where the short has not occurred without going down again due to the high place installation device 10 in which the short has occurred, so that the descending operation and the device turn-on are performed. Waiting for a power-on signal for (step S110).

Meanwhile, in FIG. 4, a process of checking the high place installation device 10 in which a power abnormality has occurred due to an overvoltage is shown. Here, the power abnormality detection unit 302 is composed of a voltage sensor. In this case, after the first circuit breaker 301 is turned off, the micom 300 turns on the circuit breaker 301 as the administrator raises the circuit breaker 301 again, and the circuit breaker 301 is momentarily turned on due to a power abnormality. When it is turned off again, it is recognized as an abnormal operation. Accordingly, the microcomputer 300 recognizes the power abnormality state by storing power abnormality state information in the memory 300b by checking whether the corresponding high place installation device is overvoltage immediately after the breaker 301 is turned off. In this case, by sequentially operating the plurality of high place installation devices 10, which are opened and closed by the same circuit breaker 301, one by one, it is possible to check which high place installation device 10 has a power abnormality.

Specifically, in a state in which the power is turned on and a power-on signal is waiting for the descending operation and the device turn-on (step S110), the process of selecting and operating one of the plurality of elevators is sequentially performed (step S111). .

The micom 300 performs driving control to operate the relay 304 connected to the high place installation device 10 when a signal for lowering the elevator 200 is detected as the manager operates the remote control 11 or the like. (Steps S112 and S113).

When a power abnormality occurs due to an overvoltage in the high place installation device 10, the circuit breaker 301 is turned off (steps S114 and S115). After checking the power abnormality, the micom 300 lowers the elevator 200 and the high place installation device 10 to the ground so that the equipment can be checked (step S116).

FIG. 5 specifically shows a process of servicing the high place installation device 10 in which a short circuit has occurred. The micom 300 operates the drive motor 113 disposed in the main body 100 when a signal for lowering the elevator body 200 is sensed as the manager operates the remote control 11 and the like to operate the drum 101. The lifting body 200 and the high place installation device 10 are lowered to the ground by rotating (steps S120 and S121). Specifically, after releasing the locking state of the stopper 106 with respect to the elevator 200, the drum 101 is rotated in the reverse direction to release the wire rope 1 through the hollow of the drum 101, and the elevator 200 You just need to descend to the ground. In order to release the locking state of the stopper 106, the drum 101 may be driven to slightly raise the lifting body 200 by slightly rotating in the forward direction. By this process, the stopper 106 escapes from the side of the lift body 200 and returns to its original position, and accordingly, the lift body 200 can be switched to a state in which it can be freely lowered.

After the elevation installation device 10 is maintained, the elevation installation device 10 may be turned on by elevating the elevator body 200 again and combining it with the main body 100 (steps S122 and S123). The hoisting operation of the wire rope 1 is performed by the drum 101 disposed in the main body 100 and rotating in the forward direction by the drive motor 113. At this time, the wire rope 1 is pulled up while passing through the hollow of the drum 101, and then the direction is switched by the guide roll 103 and wound around the drum 101.

When the lifting body 200 rises and reaches a predetermined point by the winding of the wire rope 1, the reaching state is detected by a predetermined limit switch (not shown), and the drum 101 is In addition to stopping the rotation, the locking protrusion 201 provided on the upper outer circumferential surface of the lifting body 200 is caught by the stopper 106 protruding from the inner wall of the receiving structure 105 of the coupling part 104 so that the lifting body 200 becomes the main body ( 100).

The lifting body 200 is inserted and fixed to the receiving structure 105 and at the same time, the upper contact part 109 and the lower contact part 202 contact each other to conduct electricity.
