Abstract

PURPOSE:To operate an infrared ray remote control transmitter regardless of other operating condition by detecting that other infrared ray remote control generating machine transmits the control signal of a load and controlling the action of the load when transmission is completed. CONSTITUTION:The output of an operating switch 1 is stored into an operating memory circuit 2 once, the operating condition of the stored operating switch 1 is read in accordance with the priority sequence set beforehand at a progressive circuit 3 and outputted to a PCM code generating circuit 4. The PCM code signal is modulated to the carrier by a carrier modulating circuit 5 and through a driving circuit 6, a light emitting element 7 is light-emitted. When the control signal of the load from other infrared ray remote control transmitter B is photodetected by a photodetecting element 8, the signal is amplified by an amplifier 9 and the control signal is detected by a detecting circuit 10. When the transmission of the control signal is completed, the control of the progressive circuit 3 in the standby condition is released by the output of a control circuit 11 and the usual transmitting action is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to an infrared remote control transmitter for controlling the operation of a load such as a lighting RIP soldier.

[Back Muscle Relief Technique 1] Conventionally, in this type of infrared remote control transmitter, there is generally little need to use it simultaneously when the same control 11 is open, so no consideration has been given to using multiple units at the same time. However, in large spaces such as offices, when lighting equipment, air conditioners, etc. are operated by remote control using infrared rays, multiple people may operate multiple loads at the same time. In addition, since infrared remote control transmitters used in such wide areas make the signal level as strong as possible, masking of the signal may occur depending on the usage conditions during simultaneous operation, so it is not recommended to operate multiple loads at the same time. There were times when I couldn't do it. Furthermore, if multiple infrared remote control transmitters use the same carrier frequency so that the same load can be controlled from multiple infrared remote control transmitters, P
There were cases where CM codes overlapped and code discrimination became impossible.

Therefore, the carrier frequency is changed for each infrared remote control transmitter. : However, the circuit configuration would be complicated to be able to receive signals of multiple frequencies, and it would not be effective in terms of shape and cost. Furthermore, since it is difficult to use a large number of carrier frequencies, there is a problem in that the number of infrared remote control transmitters is also limited.

[Objective of the Invention 1 The present invention has been made in view of the above-mentioned α, and its object is to provide an infrared remote control transmitter that can control the operation of loads even if multiple units are used simultaneously in the same space. Our goal is to provide the following.

[Disclosure of the Invention 1 (Embodiment) Fig. 1 is a diagram showing an embodiment of the present invention. In this embodiment, an infrared remote control transmitter is provided with a receiving function, and a certain infrared remote control transmitter A can transmit the operation of a load. When a control signal to control the load is being transmitted, another infrared remote control transmitting fiB that attempts to control the operation of the load receives this control signal, thereby confirming that the control signal is being transmitted from the infrared remote control transmitting fiA. Knowing this, the infrared remote control transmitter fiB transmits the control signal after the infrared remote control transmitter A finishes transmitting the control signal.

Specifically, an operation switch 1 that is configured by a plurality of switches and inputs control data for controlling the operation of the load;
An operation memory circuit 2 that stores the operation state of the operation switch 1, and a sequential feed circuit that outputs the operation states stored in the operation memory circuit 2 to the subsequent circuit in order of priority determined in advance for each switch. 3, a PCM code generation circuit 4 that converts the output of the sequential feed circuit 3 into a PCM code signal, a carrier modulation circuit 5 that modulates a carrier with the output of the PCM code generation circuit 4, and a light emitting element 7 that emits light according to the output of the carrier modulation circuit 5. a control signal transmitting section consisting of a drive circuit 6, a light receiving element 8 that receives a control signal transmitted from another infrared remote control transmitter B, an amplifier circuit 9 that amplifies the output of the light receiving element 8, and an amplifier circuit. The detection circuit 10 detects a control signal from the output 9, and the output generated when the detection circuit 10 detects the control signal operates the sequential feed circuit 3 of the control signal transmitting section, that is, the operation switch from the operation storage circuit 2. A transmission control section is constituted by a control circuit 11 that controls to stop the operation of reading out the operation contents of No. 1.

The operation will be explained below. First, the operation of transmitting a control signal for controlling a normal load will be explained. Data for controlling this load is inputted through the operation switch 1, and as described above, a plurality of operation switches 1 are provided. Therefore, a plurality of switches of the operation switch 1 may be operated in a short period of time, so-called simultaneously. Since there is little need for simultaneous load operations in a normal remote control transmitter, no signal is output to the subsequent circuit when the operation switches 1 are operated simultaneously. However, when controlling loads such as lighting equipment as in this embodiment, it is often desired to control a plurality of loads at the same time.

For this purpose, the output of the operation switch 1 is temporarily stored in the operation memory circuit 2, and the operation state of the operation switch 1 stored in the operation memory circuit 2 is read out in a sequential feed circuit 3 according to a preset priority order to generate a PCM code. Output to circuit 4. In this way, it is possible to handle simultaneous operations of the operation switches 1. Then, the PCM code generation circuit 4 generates a PCM code according to the operation contents of the operation switch 1.
A code signal is created, this PCM code signal is modulated to a carrier by a carrier modulation circuit 5, and a drive circuit 6
The light-emitting cable 7 is caused to emit light through the light-emitting cable 7.

Next, the operation of the transmission control section will be explained. Here, it is assumed that a load control signal from another infrared remote control transmitter B is received by the light receiving element 8. The output of this light-receiving element 8 is amplified by an amplifier circuit 9, and a detection circuit 10 detects whether the signal being transmitted from another infrared remote control emitter Mf'1jlB is a control signal for controlling the operation of the load. To detect.

By driving the control circuit 11 with the output when the control signal is detected by the detection circuit 10, the control circuit 11 is controlled.
The sequential feed circuit 3 of the l signal transmitting section temporarily stops the operation of reading out the operation contents of the operation switch 1 from the operation storage circuit 2 and outputting it to the PCM code generation circuit 4, and enters a standby state. When the transmission of the control signal from the other infrared remote control transmitter fiB is completed, the control of the sequential feed circuit 3, which has been in a standby state, is released by the output of the control circuit 11, and the normal transmission operation is performed. In this way, it is configured to detect that the other infrared remote control transmitter (i) is transmitting a load control signal, and to control the load operation when the Ike's infrared remote control transmitter finishes transmitting the load control signal. , the infrared remote control transmitter can be operated regardless of the operating state of other infrared remote control transmitters.

[Advantageous Effects of the Invention 1] As described above, the present invention includes an operation storage circuit that stores the operation state of the operation switch, and a control signal that transmits a control 1 signal that controls the operation of a load based on the stored contents of the operation storage circuit. A transmitter, a receiver circuit that receives control signals transmitted by other infrared remote control transmitters, and a receiver circuit that receives control signals from other infrared remote control transmitters. Since it is equipped with a transmission control section consisting of a control circuit that stops reading out the operation contents from the operation storage circuit, the reception circuit of the transmission control section can detect that another infrared remote control transmitter is transmitting a load control signal. The control circuit can be set to a standby state so that the control signal transmitter does not transmit a control signal to control the operation of the load until the other infrared remote control transmitter finishes transmitting. The effect is that the infrared remote control transmitters can be operated simultaneously regardless of the operating state of the infrared remote control transmitters.
