DETAILED DESCRIPTION OF THE INVENTION The present invention is a load control method that performs pattern control. Conventionally, in homes, stores, performance halls, stages, etc., there are many loads, for example electrical appliances such as lighting equipment (hereinafter referred to as controlled loads). ) are used, but these controlled loads are usually controlled individually.

However, these controlled loads, such as audio equipment,
Lighting loads, air conditioning, disaster prevention equipment, etc. are often connected to a plurality of four controlled loads that are used at the same time, and it would be very troublesome to control them individually in such cases.

The present invention provides a load control method that is not subject to regulations such as the Radio Law, is resistant to noise such as disturbances, and has excellent operability because the transmitter on the operating side is portable and wireless. There is something to do.

The present invention will be explained in detail below using examples.

FIG. 1 shows a schematic block M of an embodiment of the present invention.

This is for selecting and setting the controlled load (41) to be controlled for each system. (8) is a load control device, and the load control system vI (8) controls a predetermined controlled load among the connected controlled loads (41) based on the analysis data of the signal analysis circuit (7). The load (41)... is selected and each controlled load (41)... is controlled according to predetermined control details. In this case, if it is pattern control, the controlled load (41) and

1) Assuming that the system is installed in a large store such as a supermarket or department store, the use of the circuit shown in FIG. 1 according to the load control method of the present invention will be explained below.

First, in large stores such as supermarkets and department stores, the situation changes depending on conditions such as the day shoppers come and go in the sales floor, the time of day, and the weather. As a result, the sales areas that are crowded and those that are not will also change. Therefore, it is necessary to change the brightness of the lighting load depending on the number of customers, but in the embodiment shown in FIG.
By simply importing the pattern control selection data set according to other conditions, the desired pattern control data can be sent to the preparation section, and the receiving section
(By receiving and analyzing the incoming optical signal, it is possible to turn on, turn off, or control a predetermined controlled load (41), which is a lighting load, to a predetermined dimming level.
The operation of the I4 aircraft may be combined with the lighting control pattern to match the number of customers. Of course, more detailed control may be performed by selectively controlling individual controlled loads (41) depending on the situation. Of course, this lighting load control can be used for stage lighting, exhibition lighting, performance halls, and at home.

In addition to lighting loads and air conditioners, for example, it may be used for pattern control of audio equipment, etc. that is operated by a combination of lighting loads, air conditioners, etc.).

As shown in FIG. 3, the surface light transmitter fl+ includes a microphone (1) for determining input data from the +- board (31) and creating parallel predetermined code signals:
, a parallel/serial converter tto+ that converts the parallel code signals from the microphone 0 (9) and the microphone 0 (9) into a serial code signal, and the parallel/serial converter +101. For example, the serial code signal has a pulse width of logical value 111, 10I.
A pulse width modulation circuit (11) sets and modulates the pulse width modulation circuit (11), and a light emitting element (5) such as a semiconductor laser or a light emitting diode is driven by the modulation output of the nuclear pulse width modulation circuit (ll).
It is composed of a light emitting drive circuit (12) and a light emitting element (5), which causes the light to flash and generate a pulse-modulated optical signal x1. The circuit in Figure 3 uses pulse width modulation,
Pulse modulation methods such as pulse code variation and pulse number modulation may also be used. -As shown in Fig. 4, the force sensing receiver (6) includes a light receiving element such as a photodiode that receives the optical signal an optical signal detection circuit (I4) that detects a signal; and a demodulation circuit Q6 that demodulates the serial pulse width modulated pulse signal obtained from the optical signal detection circuit α and converts it into the original parallel code signal. The control content of the demodulation code signal of this demodulation circuit is determined by the above-mentioned signal analysis circuit (). Furthermore, the demodulation circuit 0 is used depending on the pulse modulation method of the optical transmitter (6), and if it is other pulse modulation such as pulse number modulation or pulse code modulation, the one corresponding to the pulse modulation method is used. Needless to say, it can be done.

Furthermore, when creating the optical signal I, a start pulse is inserted before the data signal to take a period of time, and a 1 esid pulse is inserted afterwards to indicate the end, or a specific receiver (6
) may be included.The present invention is capable of translating a pattern control signal converted into a specific code for controlling a predetermined combination of controlled loads among a plurality of controlled loads as an optical signal. a portable optical transmitter that emits and transmits data to a computer, a receiving means that receives and detects a specified optical signal that has propagated in space, and demodulates a pattern control signal; Selectively controls the controlled load corresponding to the pattern control content selected and determined by the signal analysis means that selects and determines the pattern control content that is preset corresponding to the control signal, and the inner core signal analysis unit of the connected controlled load. The present invention is equipped with an optical receiver equipped with a load control means to control the controlled loads by a spatially propagated optical signal, so that it is possible to remotely control a plurality of related controlled loads with a single operation. It is easier to operate than when controlling individual controlled loads, and since it is performed using optical signals, there are no legal regulations or effects on other equipment like with radio waves. Since the optical transmitter is portable, it can be used on the spot.
It is possible to perform on-the-spot control, further improving operability, and since it is converted into an optical signal of a specific code, there are fewer recreational operations caused by external noise, and the reliability of the device is improved.
