Abstract

PURPOSE:To allow the integrated control of apparatus of different kinds and the setting of the control varying with each of the respective apparatus by providing a pattern memory section in wireless signal receivers and setting a pattern setting instruction and a pattern reproduction instruction as control codes. CONSTITUTION:The apparatus 1 to 4 stored with the same pattern numbers in the pattern memory section 15 are integrally and simultaneously controlled upon receipt of the pattern reproduction instruction if the respective wireless signal receivers 5 are subjected to the setting by the pattern setting instruction by transmitting the pattern setting instruction from a wireless signal transmitter 6 when illuminating appliances 1, 2, an air cleaner 3 and a motor operated curtain 4 are connected as the loads of the respective wireless signal receivers 5. Plural pieces of the pattern number can be set for one signal receiver 5 and, therefore, the control states are discretely set for the apparatus 1 to 4. The integral and simultaneous operation of these apparatus by one time of the operation of the signal transmitter 6 is then possible.

Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to an optical wireless transmission system that remotely controls various devices installed in a house or in a building using optical wireless signals.

[Conventional technology]

2. Description of the Related Art Conventionally, remote control devices have been provided that remotely control various devices installed in houses and buildings using optical wireless signals. The wireless signal transmission format in this type of remote control device is as shown in Figure 8, and basically consists of a device code DV indicating the type of device, and an address code AD individually given to each device.
, and a control code CN that instructs the content of control of each device. Furthermore, the device code DV consists of a product group code GC that indicates the type of device such as a lighting fixture or an air purifier, and a product name code PC that indicates the individual product name of each product group. It consists of an operation code OP that instructs the type of control such as off control or dimming control, and an operand code RD that instructs the specific content and level of control. Therefore, as shown in FIG. 7, the following steps are taken to control each of the various devices installed indoors, such as lighting fixtures 1 and 2, air purifier 3, and electric curtain 4. That is, a wireless receiver 5 is connected to each of the devices 1 to 4, and a wireless signal of the above format is transmitted from the wireless transmitter 6 using light such as infrared rays. In the wireless receiver, when the preset device code DV and address code AD match those included in the wireless signal, each device 1 to 4 is controlled according to the control code CN included in the wireless signal. be.

[Problem to be solved by the invention]

In the above configuration, in one operation of the wireless transmitter 6,
Only one device 1 to 4 can be controlled. However, there are cases where it is necessary to control a plurality of devices 1 to 4 at the same time, and there is a problem in that the above configuration cannot satisfy such requirements. Here, for devices with the same device code, it is possible to control multiple devices at once by matching only the address code AD, but in this case, the control codes are the same. Therefore, it is only possible to set each device to a different state. Moreover, devices with different device codes cannot even be controlled all at once. The present invention aims to solve the above-mentioned problems, and is an optical wireless device that allows devices of different types to be controlled at the same time, and also allows different control states to be set for each device. The aim is to provide a transmission method.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an optical system that transmits a wireless optical signal from a wireless transmitter, receives the wireless signal by a wireless receiver connected to each device, and controls each device. In the wireless transmission system, the wireless signal includes a device code indicating the type of device, an address code indicating an address individually given to each device, and a control code indicating the control details for the device. is equipped with a pattern storage section, and when the control code is a pattern setting command, the control state of the device at that time is stored in the pattern storage section along with a pattern number that identifies the type of pattern, and the device code is stored in the pattern storage section. Covers all equipment,
When the control code is a control code or a pattern playback command, each wireless receiver that has a pattern number that matches the pattern number included in the pattern playback command or that is stored in the pattern storage unit ignores the type of device and receives the wireless signal. The control state corresponding to the pattern number included in the pattern number is read out from the pattern storage section and each connected device is controlled to that control state.

[Effect]

According to the above configuration, the wireless receiver is provided with a pattern storage unit, and a pattern setting command and a pattern reproduction command are set as control codes, and when the control code is a pattern setting command, together with a pattern number for identifying the type of pattern. The control status of the device at that time is stored in the pattern storage unit, and if the device code is targeted at all devices, and the control code is a pattern playback command, the pattern number that matches the pattern number included in the pattern playback command is Each wireless receiver stored in the pattern storage section ignores the type of device and reads the control state corresponding to the pattern number included in the wireless signal from the pattern storage section to control each connected device. Since the control is controlled to that control state, wireless receivers with the same pattern number set by the pattern setting command can be controlled all at once regardless of the type of device, and each device can be controlled at the same time. The control state is reproduced as it was at the time the pattern setting command was received, and the control state can be set individually for each device. In short, it is possible to individually set the control status of multiple types of devices and operate them all at the same time with a single operation of the wireless transmitter.

【Example】

As shown in FIG. 1, a wireless signal using light such as infrared light is transmitted from the wireless transmitter 6, and when the wireless signal is received by the wireless receiver 5, it is connected to each wireless receiver 5 as a load 7. Each device is controlled based on control information included in the wireless signal. The wireless signal, as before, uses the device code DV.
(product group code GC and product name code PC), address code)'AD, control code CN (operation code O
P and operand code RD) (see Figure 8). However, as the product group code GC, there is a code that can specify all devices regardless of the type of device (common code), and as the operation code OP,
A pattern setting command and a pattern reproduction command are provided. Further, as shown in FIG. 1, the wireless receiver 5 includes a light receiving element 11 that receives a wireless signal, a light receiving circuit 12 that amplifies or waveforms the output of the light receiving element 11, and a light receiving circuit 12 based on the output of the light receiving circuit 12. A signal processing circuit 13 consisting of a microprocessor that controls the load 7, a device code DV
and a setting switch 14 for setting address code AD, and a pattern storage section 15 for storing pattern numbers, etc., which will be described later.
It is made up of. First, as shown in Figure 3, the operation code OP
The operation will be described when the pattern setting command PS is used. In this case, the pattern number PN is designated as the operand code RD. Further, other codes of the wireless signal are the same as when the loads 7 are individually controlled. When the signal processing circuit 13 of the wireless receiver 5 confirms that the wireless signal is a regular signal, as shown in FIG.
It is checked whether the address code AD or address code AD matches what is included in the wireless signal, and if they match, the operation code OP is decoded. When the operation code is OP or the pattern setting command PS, the control data indicating the control state of the load 7 at that time (that is, corresponds to the control code CN when controlling the load 7),
The pattern number PN set as the operand code RD is assigned and stored in the pattern storage unit 15. Such processing is performed on all wireless receivers 5 to which devices to be simultaneously controlled are connected as loads 7. Here, the same pattern number PN is assigned to the wireless receivers 5 that are to be controlled simultaneously. On the other hand, when controlling multiple devices at once,
As shown in FIG. 5, the wireless transmitter 6 sends out a wireless signal in which the operation code OP is a pattern reproduction command PR and the operand code RD is a pattern number PN. At this time, the product group code GC is set to a common code COM that applies to all devices. Upon receiving such a wireless signal, the wireless receiver 5 operates as shown in FIG. That is, after confirming that the wireless signal is a regular signal, if it is determined that the product group code GC is the common code COM and the operation code OP is the pattern reproduction instruction PR, then the operand code RD is determined. A certain pattern number P
A pattern number matching N is searched in the pattern storage section 15, and control data corresponding to the pattern number is read out. In this way, the control state of the load 7 is reproduced based on the control data read out from the pattern storage section 15. Here, when the product group code GC is the common code COM, the product name code PC and address code AD are ignored, and the pattern number PN specified by the operand code RD is the same as that of the pattern storage unit 15. The wireless receiver 5 stored in the wireless receiver 5 will be controlled regardless of the type of load 7. Therefore, as shown in FIG. 6, in a case where lighting fixtures 1 and 2, air purifier 3, and electric curtain 4 are connected as loads 7 to each wireless receiver 5,
If each wireless receiver 5 is configured in advance using a pattern setting command PS, when a pattern reproduction command PR is received, it is possible to select one of the devices 1 to 4 with the same pattern number stored in the pattern storage section 15. - They are all controlled at the same time. The pattern number is
Since it is possible to set a plurality of devices for one wireless receiver 5, it is possible to control each device 1 to 4 in a plurality of patterns depending on the control state of each device.

【Effect of the invention】

As described above, the present invention provides a wireless receiver with a pattern storage section, sets a pattern setting command and a pattern playback command as a control code, and when the control code is a pattern setting command, a pattern identifying the type of pattern is provided. The control state of the device at that time is stored in the pattern storage unit along with the number, and if the target is a device hood or all devices, and it is a control code or a pattern playback command, a pattern that matches the pattern number included in the pattern playback command. Each wireless receiver whose number or pattern is stored in its memory ignores the type of device, reads the control state corresponding to the pattern number included in the wireless signal from its pattern memory, and displays each connected Since the device is controlled to the control state, wireless receivers having the same pattern number set by the pattern setting command can be controlled all at once, regardless of the type of device. Furthermore, the control state of each device is reproduced as it was at the time the pattern setting command was received, and the effect is that the control state can be set individually for each device. In short, it is possible to individually set the control status of multiple types of devices and to operate them all at the same time with a single operation of the wireless transmitter.
