Abstract

PROBLEM TO BE SOLVED: To provide a reasonable port signal setting device by using a rotary dip switch with a number of rotational positions. SOLUTION: For a part signal setting device, H/L signals are given to plural ports D1-D4 in a microcomputer 14 via a rotary dip switch 13 (simply called a switch thereafter) with a diameter-directional cut groove formed on the front face of a shaft and a panel with a hole which the shaft faces is provided. The shaft has at least four rotational positions in even number (ten rotational positions as indicated) and the microcomputer 14 has a reading means to read input signals to the ports D1-D4 corresponding to the opposite rotational positions of the shaft as the same signal. Indication codes (1-5 as shown) in half (5 as indicated) of the number of the positional positions of the shaft (10 as indicated) are shown on a panel. The indication codes can be shown in the same number as the number of the rotational positions of the shaft. That is, the same indication codes can be shown even on the opposite sides of the indication codes so that the indication codes can be shown all over the periphery.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a port signal setting device for a microcomputer.

[0002]

2. Description of the Related Art In an infrared remote control transmitter for lighting equipment, a channel corresponding to a channel set on the lighting equipment can be set on the transmitter, and the remote control can be performed only when the channel settings match. Become. When, for example, an H / L signal is supplied to a plurality of ports of the microcomputer via an existing rotary dip switch and used for channel setting, different signal sets corresponding to the respective rotational positions of the rotating shaft are input to the ports. Will be done.

[0003]

However, if not a large number of channels is required, empty channel positions will be created, causing confusion for the user. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a reasonable port signal setting device using a rotary DIP switch having a large number of rotational positions.

[0004]

SUMMARY OF THE INVENTION In summary, the present invention provides an H / L signal to a plurality of ports of a microcomputer via a rotary dip switch having a diametrically cut groove formed on the front surface of a rotating shaft, and further comprises the steps of: A port signal setting device including a panel having a hole facing an axis, wherein the rotation axis has four or more even rotation positions, and the microcomputer corresponds to rotation positions opposite to the rotation axis. A port signal setting device comprising means for reading an input signal to a port as the same signal, wherein the panel displays a display code of a half of the number of rotation positions of the rotating shaft or a display code of the same number as the number of rotation positions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described. However, these are merely exemplary embodiments adopted based on the present invention, and the present invention is limited to matters unique to only the embodiments. The technical scope of the present invention must be determined based on the matters stated in the claims or matters that are substantially equivalent thereto.

In the illustrated embodiment, a rotary dip switch (hereinafter simply referred to as a switch) 13 having a diametrically cut groove 12 formed on the front surface of a rotating shaft 11 is used for H / L.
This is a port signal setting device that provides a signal to a plurality of ports D1 to D4 of a microcomputer 14 and includes a panel 16 in which a hole 15 facing the rotating shaft 11 is formed. The rotation shaft 11 has four or more even rotation positions (10 rotation positions are illustrated), and the microcomputer 14 controls the rotation shaft 1
The ports D respectively corresponding to diametrically opposite rotational positions
The panel 16 is provided with means for reading the input signals to 1 to D4 as the same signal. Is displayed). Also, the rotating shaft 11
May be displayed as many display codes as the number of rotation positions of. That is, it is also possible to display the same display code on the opposite side of each display code in FIGS. 1 and 2 and display the display code over the entire circumference.

The entire apparatus shown in FIG. 1 is mounted on a wall such as a corridor or stairs. When an approach of a human body is detected by a human body sensor 17, it is converted into an infrared remote control signal and transmitted from a light transmitting cover 18 to a lighting fixture (not shown). Then, the lighting equipment is turned on. The channel corresponding to the channel set by the lighting fixture is set by rotating the rotating shaft 11. For example, in FIG. 1, channel 2 is set.

The switch 13 has 10 rotational positions in total, and an L level signal is supplied to the switch 13 from the signal terminal D0 of the microcomputer 14, and as shown in FIG. The switch switching state inside the switch 13 changes in a binary number, and
Different signal sets are provided to D4. For example, at the panel display position 2 (corresponding to the switch rotation position 1) of the rotating shaft 11 shown in FIGS.
H, D3 = H, and D4 = L. By the way, the rotating shaft 11
Is rotated to a rotational position opposite to that shown in FIGS.
The direction corresponding to the switch rotation position 6 is input to the ports D1 to D4 without changing the direction of the switch 2 on the surface.
= H, D2 = L, D3 = L, D4 = H. this is,
The ports D1 = H, D2 = H, D3 = H, and D4 = L are of course different signal sets, but if the microcomputer 14 reads the two sets as the same signal, the signal corresponding to the switch rotation position 6 will be the switch rotation. This is the same as the signal corresponding to position 1. This same signal interpretation can be easily set by software. As a result, each port signal corresponding to the opposite rotation position of the rotation shaft 11 can be read as the same signal, and a reasonable port signal setting device can be provided. Further, when the display codes (1 to 5) of the half of the number of rotation positions of the rotating shaft 11 are displayed on the panel 16, a port signal setting device which is clear from the display surface can be provided. Note that a signal from the human body sensor 17 is input to the microcomputer 14, and an infrared light emitting element (not shown) is driven from the output OUT of the microcomputer 14 by the converted signal.
