Description

Detailed Description of the Invention 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a transmission control device that remotely controls a plurality of devices using a transmission channel.

BACKGROUND OF THE INVENTION Many transmission control devices that remotely control multiple devices using conventional technology transmission channels have been reported. As the transmission communication path, it is possible to use a power line, a coaxial line, a zero-source cable line, a telephone line, etc. depending on the purpose of the box. A plurality of terminal devices are connected to these transmission communication paths. Terminal equipment is electrical equipment connected to the self (lighting, etc.).

It has the ability to directly control air conditioners (air conditioners, etc.). Control details include turning off equipment and brightness/darkness of lighting.

There are many possibilities, such as switching between cooling and heating in an air conditioner.

Transmits control signals to terminal equipment via transmission communication channels,
Also, a control@device has a centralized monitoring control function of displaying the status of the device transmitted from the terminal device.

A control device generally has an operation section and a display section in order to perform all of the above-mentioned functions. The operating part is usually a switch, and the display part is usually a lamp. That is, the user presses a switch to control the device and confirms the control result by looking at the lamp. Now, it is possible to use a remote control device as the operation section of the control device, and a display device such as a television receiver as the display section. By using both, the user can control the equipment with a remote control device from a distance from the control equipment,
The control results can be confirmed on a display device with a large display surface and good visibility even from a distance. FIG. 2 shows a transmission control device using this remote control device and display device. When the user presses the push button switch 2 of the remote control device 1, a remote control signal is input to the remote control receiving means 6 of the control device 4, and the arithmetic control means 6 to which this signal has been input uses the transmitting/receiving means 7. , transmits control signals to the power line 8, which is a transmission communication path. The terminal device 9 that has received the control signal controls the device 10 connected to itself according to the control content. Here, it is assumed that the device 10 is controlled from OFF to ON. Then, the terminal device 9 transmits a signal to the power line 8 indicating that the device 10 is turned on. The arithmetic control means 6 which received this signal via the transmitting/receiving means 7 causes the image generating means 11 to generate an image indicating that the device 10 has turned OW. This image is displayed on the display device 12 connected to the control device 4, and the user confirms that the control has been executed. The above is a series of control processes.

Problems to be Solved by the Invention A remote control device has the advantage that it can be controlled from anywhere within the range of its signal. Therefore, it can be placed anywhere, such as on a desk or on the floor.

Since it can be placed anywhere, there is a possibility of inadvertent manipulation. For example, this could be caused by placing your elbow on the edge of a push button switch of a remote control device, placing something on it, or dropping something on it. Now, a display device generally has a plurality of display modes. For example, in the case of a television receiver, there are a television broadcast mode, a video mode, and an RGB mode. Therefore, when a remote control device is inadvertently operated, the television receiver does not necessarily display the control screen.

This means that one of the devices is malfunctioning without the user's knowledge, which may lead to danger.

The present invention aims to eliminate the danger associated with this unconscious operation.

Means for Solving the Problems In order to solve the above-mentioned problems, the transmission control device of the present invention includes a transmission communication path, a terminal device that controls the equipment connected to the transmission communication path and connected to itself, and a transmission control device that also controls the transmission communication path. a control device connected to a transmission/reception means, an arithmetic control means, an image generation means, a display switching means for switching the display mode of a display device connected to the control device, and a remote control signal receiving means for receiving a remote control signal; It consists of a display device that displays a control screen and a remote control device that sends remote control signals to the control device.

Effect With the above configuration, when the remote control counter is operated, the control device forcibly switches the display mode of the display device to a specific mode.

Embodiment FIG. 1 is a configuration diagram showing an embodiment of a transmission control device of the present invention.

A terminal device 14 is connected to the power line 13, which is one of the communication transmission paths. The terminal device 14 has a function of directly controlling the device 15 connected to itself. A control device 16 is also connected to the power line 13 .

The arithmetic control means 17 of the control device 16 transmits and receives transmission signals to and from the power line 13 via the transmitting and receiving means 18. The arithmetic control means 17 is also connected to a remote control signal receiving means 19 to receive remote control signals.

The arithmetic control means 17 further prompts the video generation means 20 to generate a necessary control screen. A video signal generated by the video generating means 2o is input to a display device 21 such as a television receiver, and a necessary control screen is displayed. Arithmetic control means 17
is connected to the display switching means 22 and urges the display device 21 to generate a display mode switching signal. The output of the display switching means 22 is connected to the display mode switching terminal 23 of the display device 21, and the display mode of the display device 21 is switched as necessary.

The method of switching the display mode of the display device 21 is an existing technique. When the user controls the device 15, the user uses the remote control device 2
4. Press the push button switch 25. Then, the control signal is sent to the remote side (goods) signal receiving means 19.calculation control means 17. Transmitting/receiving means 18. The signal is transmitted to the terminal device 14 via the power line 13, and the device 15 is controlled. When the control of the device 16 is completed, a signal to that effect is transmitted from the terminal device 14 to the power line 13.
．． It is transmitted to the calculation control means 17 via the transmission and reception means 18. A video signal indicating that the control of the device 15 has been completed according to the command from the arithmetic control means 17 is displayed on the device 21 comprising the video generation means 2o. Generally, before performing control, the operator switches the display mode of the display device 21 to display the desired control screen and then performs control to prevent malfunctions. When the push button switch 26 is pressed and a control signal is input to the arithmetic control means 17 via the remote control receiving means 19, the arithmetic means 17 must first command the display switching means 22 to switch the display device. The display mode is forcibly switched to the display mode switching terminal 23 of 21 so that the desired control screen is displayed. By doing this, even if you inadvertently perform an erroneous operation, the results of the control will be displayed on the display device 21.
The user will later be able to notice that the control has been implemented, and will no longer remain unaware that the control has been implemented.

Effects of the Invention According to the present invention, it is possible to always display the control results of the device on the display device and notify the person who uses the ash. This can prevent situations that could lead to danger. In other words, this has the effect of increasing the safety of the device. In addition, if the user does not notice that the device has been turned on due to an incorrect operation, the device will operate unnecessarily, which is wasteful. However, if the user notices the incorrect operation, he can immediately turn off the device and do not waste electricity. It also has the effect of becoming an economical device.
