Abstract

PROBLEM TO BE SOLVED: To facilitate the channel setting in the remote controlled illumination apparatus that has a plurality of channels mounted with a microcomputer. SOLUTION: When the microcomputer is not in the state of power-on reset as in the case of non-operability by the normal routine, the RAM is cleared and the memory contents of the ROM is read by the RAM and the receiving channel and lighting conditions or the like are initialized to the set content at the time of factory shipment. Then, the microcomputer returns automatically to the channel setting mode, thereby, by receiving the remote control signal 3, the code is read and it is automatically set to the channel corresponding to the code, and returns to the channel used previously. At this point, the microcomputer returns to the normal mode, and the lighting conditions of the lamp can be controlled when it receives the remote control signal 3.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control lighting apparatus which facilitates channel setting. 2. Description of the Related Art In order to avoid interference from a plurality of remote control transmitters when a plurality of remote control lighting units are used in a room, each remote control lighting unit is readable by a microcomputer mounted on each of them. Remote control code (hereinafter simply,
(Referred to as a code) can be set to one of a plurality of types, and this is generally referred to as corresponding to a plurality of channels. The remote control transmitter also has a channel setting switch so that different codes can be set to be transmittable corresponding to the plurality of channels. To set the remote control lighting fixture to the desired channel when installing the fixture, press the channel setting mode button provided on the remote control lighting fixture, and then set the desired channel set with the channel setting switch on the remote control transmitter. To send a remote control signal. Then, when the microcomputer of the remote control lighting apparatus reads the code, the code of the remote control lighting apparatus is automatically set to a readable channel and stored in the EEPROM of the remote control lighting apparatus. Also, the remote control lighting equipment generally has a function to reset the microcomputer by a watchdog timer, etc., and return the microcomputer to a normal state when the microcomputer stops operating in a regular routine due to noise etc. is there. [0003] However, when the microcomputer is reset, the RAM is cleared, and the program contents stored in the remote control lighting device at the time of factory shipment are stored in the RAM.
Since the microcomputer returned to the normal mode while the memory contents of the OM were read into the RAM,
The channel is set to the initial value of the factory default of the remote control lighting fixture. For this reason, if the user has previously used a channel different from that channel, it is necessary to return to that channel.To do so, as with the installation of the fixture, press the channel setting mode button on the remote control lighting fixture side. After that, the remote control transmitter must be operated to transmit the remote control signal. In this case, it is troublesome especially when the channel setting mode button must be depressed after removing the glove at a high place such as a remote control lighting device for a ceiling. Accordingly, an object of the present invention is to provide a remote-control lighting device that can easily set channels in view of the problems to be solved. SUMMARY OF THE INVENTION In summary, in a remote control lighting apparatus equipped with a microcomputer and corresponding to a plurality of channels, when the microcomputer does not operate in a regular routine due to noise or the like, an automatic operation is performed. Remote control having a function of returning the microcomputer to a normal state, and further having a function of reading a code by receiving a remote control signal transmitted by a remote control transmitter and setting a channel corresponding to the code. It is a lighting fixture. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described, which are merely exemplary embodiments adopted based on the present invention, and the present invention is not limited to the specific embodiments. The technical interpretation of the present invention should be determined based on the matters stated in the claims and the matters substantially equivalent to the matters described in the claims. The embodiment shown in FIG. 1 shows a remote control transmitter 1 and a remote control lighting device 2, and a remote control signal 3 coded by infrared transmission transmitted from the remote control transmitter 1.
The lighting state of the lamp 4 is controlled by the remote control lighting fixture 2 receiving and reading the received signal. The remote control lighting apparatus 2 includes a light receiving module 5 for receiving the remote control signal 3, a microcomputer 6 for reading a code demodulated by the light receiving module 5 and outputting a predetermined control signal, and a lamp based on the control signal from the microcomputer 6. And a driver 7 for driving the driver 4. The microcomputer 6 shows a one-chip type,
The inside thereof includes a CPU, a ROM, a RAM, a watchdog timer, a timer, and the like. In addition, microcomputer 6
Are connected to an external component such as an EEPROM, a clock, a channel setting mode button (switch) 8, and the like. It should be noted that the ROM stores the program contents at the time of factory shipment including the receiving channel, and the EEPROM stores changed items such as the receiving channel set by the user independently. The remote control lighting apparatus 2 is of a type that supports a plurality of channels, and a code readable by the microcomputer 6 can be set to any one of a plurality of channels. Here, it is assumed that there are two channels, channel A and channel B. The remote control transmitter 1 also includes a channel setting switch (not shown) so that different codes corresponding to the plurality of channels can be set to be transmittable. In order to set the remote control lighting apparatus 2 side to a desired channel at the time of installing the apparatus, after pressing a channel setting mode button 8 provided on the remote control lighting apparatus 2 side, the setting is performed by a channel setting switch of the remote control transmitter 1 side. The remote control signal 3 may be transmitted on a desired channel. Then, when the microcomputer 6 of the remote control lighting device 2 reads the code, the remote control lighting device 2 is automatically set to a channel that can read the code, for example, the channel B. Then, the setting channel of the remote control transmitter 1 and the setting channel of the remote control lighting fixture 2 match. Thereafter, the lighting state of the lamp 4 of the remote control lighting fixture 2 can be controlled by remote control by the remote control transmitter 1. The remote control lighting apparatus 2 has a function of resetting the microcomputer 6 by a watchdog timer or the like and returning the microcomputer to a normal state when the microcomputer 6 stops operating in a regular routine due to noise or the like. I have.
Here, conventionally, when the microcomputer 6 is reset,
The area is cleared, the contents stored in the ROM are read into the RAM, and the microcomputer 6 returns to the normal mode while the receiving channel is initialized. For this reason, when the channel of the initial value which is the factory default of the remote control lighting device 2 is, for example, channel A,
It will be set to channel A. Then, when the user has previously used the channel B different from the channel A, it is necessary to return to the channel B. To do so, the user presses the channel setting mode button 8 on the remote control lighting fixture 2 side. The remote control signal 1 must be transmitted by the remote control transmitter 1, especially when the channel setting mode button 8 has to be pressed after removing a glove at a high place like a remote control lighting device for a ceiling. It was something that was hanging. Therefore, in the present embodiment, when the microcomputer 6 stops operating in a normal routine due to noise or the like, the program is automatically started from address 0 by a watchdog timer or the like, the RAM is cleared, and the receiving channel is changed. Initialization is performed, and then the mode automatically changes to the channel setting mode corresponding to pressing the channel setting mode button 8. Then, the code is read by receiving the remote control signal 3 transmitted by the remote control transmitter 1 operated by the user, and is automatically set to the channel corresponding to the code, in this case, the channel B, and is used previously. Will return to your channel In this way, the user does not particularly care whether the operation of the microcomputer 6 has become abnormal or not, and simply operates the remote control transmitter 1 to return the reception channel of the remote control lighting fixture 2 to the previously used channel. Thus, it is possible to provide a remote control lighting device with easy channel setting. FIG. 2 shows a state of a reset start when the microcomputer 6 stops operating in a regular routine. First, it is determined whether or not the reset is a so-called power-on reset when the power to the remote control lighting apparatus 2 is turned on. I do. In the case of a power-on reset, as is well known, the storage contents of the EEPROM in which the change contents set by the user such as the reception channel are stored are read into the RAM,
It will be the channel that was stored. Thereafter, the normal mode is set, and when the remote control signal 3 is received, the lighting state of the lamp 4 is controlled. If the power-on reset is not performed as in the case where the microcomputer 6 does not operate in the normal routine, the RAM is cleared and the contents stored in the ROM are read into the RAM, and the reception channel and the lighting state are set to the factory default settings. Is initialized to After that, since the mode is automatically set to the channel setting mode, the code is read by receiving the remote control signal 3, and the channel corresponding to the code is automatically set to the channel B in this case, and the channel used previously is set. Return to Here, in the normal mode, when the remote control signal 3 is received, the lighting state of the lamp 4 can be controlled. In the latter case,
The reason that the contents stored in the EEPROM are not read into the RAM is
This is because there is a possibility that the operation of the microcomputer 6 becomes abnormal due to a defect in the storage content of the EEPROM.
