DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. That is, the lighting elevator control device includes a storage unit 1 and a timer mode control unit 2.
And preset mode control means 3. First, FIG.
Will be described. In FIG. 3, reference numeral 4 denotes a main body of an auto lifter mounted on a ceiling or the like, which includes a motor 5, a control unit 6, and a transmission unit 7. The control unit 6 and the transmission unit 7 rotate the motor 5 on a drum (not shown). Then, the rope 8 such as a wire rope wound around the drum is rewound or wound up depending on the rotation direction of the motor 5, and the lighting fixture is hung at the stop position by the rope 8 when the motor 5 is stopped. Reference numeral 9 denotes an object-to-be-elevated connection part, which connects a lighting fixture (not shown). Reference numeral 10 denotes a pulley provided on the connection portion 9 of the object to be lifted and around which the rope 8 is wound.

When the motor 5 rotates in one direction, the object connection portion 9 rises via the drum and the rope 8, and when the motor 5 rotates in the opposite direction, the object connection portion 9 descends. When the rotation of 5 stops, the connection section 9 of the object to be lifted and stopped stops at that position. FIG. 2 shows a control panel 11 of the auto lifter, 12 is a contact output unit, 13 is a power supply unit, 14 is a signal input / output unit for control contents, and 15 is a control unit. The electric power supplied to the motor 5 is controlled by the contact output unit 12 of the control panel 11, and is supplied so as to rotate the motor 5 in the upward direction of the lighting fixture or to rotate the motor 5 in the downward direction of the lighting fixture. This contact output unit 12 also outputs to the multiplex signal line system. The signal input / output unit 14 performs an up / down operation by a switch, sets a time in the case of a timer mode control unit, and manually performs a stop operation by a switch to set a fall time in the case of a preset mode control unit. , An operation unit for designating or switching modes, and a display unit for displaying each mode.

The control unit 15 includes the configuration of the control device of this embodiment. In FIG. 1, a storage unit 1 stores a descent time of the lighting elevating device. The preset mode control means 3 has a preset unit (not shown) which counts down time when a lighting fixture is manually lowered to an arbitrary position by a counter and stores it in the storage means 1.
A second timer (not shown) for setting (referencing) the falling time of the lighting device to the timer time, and automatically stopping the lighting device by the operation of the second timer when the lighting device is lowered. In the preset mode control means of the embodiment, the stop position of the lighting equipment of the auto lifter by manual operation is stored in the storage means 1 as a time value, and when the lighting equipment is lowered next time, the lighting equipment is operated by the time value. To stop. Then, the time value at this time is stored again. By repeating this, the time value is updated. That is, even when the stop position is changed by a manual operation, the last changed position is stored.

The timer mode control means 2 has a timer time setting section (not shown) for manually storing the descent time in the storage means 1, and sets (refers to) the descent time of the storage means 1 to the timer time. It has one timer (not shown) and automatically stops the lighting fixture by the operation of the first timer when the lighting fixture is lowered. The timer mode control means of the embodiment uses the time value stored in the storage means 1, in other words, the value stored in the preset mode control means, so that the stop position is determined in advance. . At this time, if the time value of the first timer is manually changed, the fall time is stored in the storage means 1, so that the time value of the preset mode control means is not limited to the change by the timer mode control means. Becomes That is, the timer mode control means and the preset mode control means go to the common value of the storage means 1 stored in the same area when referring to the time value. Therefore, when it is changed, the common value is changed, and the two modes have the same time value.

FIG. 4 shows a control flow of the preset mode control means and the timer mode control means. In the timer mode control means determines whether or not the setting time of the timer in step S _1, enter the timer time in step S ₂ If YES, the storage means 1 that the current count value as the time value in step S ₃ for example the process proceeds to step S ₄ stored in the EEPROM, the process proceeds a time value storage means 1 if NO immediately step S ₄ to the timer time. Step S ₄ in UP switch, to determine the presence or absence of the input of the stop switch and the down switch, when the UP switch increases the processing at step S _5, only lowered the processing when the fall time of the storage unit 1 in step S ₆ the lowering switch , processing stops at step S ₇ when stop switch.

In the preset mode control means, the step

As a result, in each operation mode, the latest setting of the fall time of the storage means 1 is automatically set as the setting of each operation mode. According to this embodiment, instead of having the handling of the descent time input in each mode in each mode, the value of the mode finally input becomes common to all modes, and the stored value is rewritten. Therefore, there is no difference in the stop position due to the difference in the mode, and it is possible to stop at the same position regardless of the operation in any mode. For this reason, even if there is a mistake in mode selection, there is only one type of stop position, and there is no need to stop past the intended stop position.

Further, since there is no difference in the stop position by the operator, the stop position can be reproduced even in a mode different from the last storage mode. This can be expressed by a very simple and clear deceleration in which the last set value is stored and reproduced, not by the mode in which the stop position is set. In addition, it is sufficient to operate in a desired mode without being conscious of the mode, which simplifies and clarifies how to use, and is effective as a system on the operator's side.

[0015]

According to the lighting elevation control apparatus of the first aspect, both the timer mode control means and the preset mode control means can automatically stop the lighting equipment at the falling time stored in the storage means. Therefore, there is no difference in the stop position due to the difference in the mode, and it is possible to stop at the same position regardless of the operation in any mode.
