Abstract

PURPOSE:To accurately and rapidly execute the work of setting program data by providing a display means to a controller, displaying and confirming set program data collectively and transmitting said data to an controller collectively. CONSTITUTION:The displayer 12 and a data transmission button 13 are provided together with an operational keyboard 14, transmitter 15, and a receiver 16 on the controller 11-side. A receiver 17 and a transmitter 18 are provided to the controller 19 side to be controlled. From the equipment 11-side, a data transmission start request signal is transmitted at the state displaying word data in the displayer 12. Upon receiving a reception acknowledgement signal from the equipment 19, the controller 11 transmits the first word of plural word data, then the equipment 19 stores the words in a memory, and at the same time, and returns them to the controller 11. In case of coincidence between the two data above, the controller 11 transmits a data coincidence detection signal, so that the equipment 19 recognizes the formerly stored data as normal data, then request for the transmission of the following data. The above processing is repeated to complete the transmission of plural word data.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control system for transmitting a plurality of word data, in which a display device for displaying word data to be transmitted is provided on the control device side.

Conventionally, in a remote control system that transmits and receives several word data, as shown in FIG. , is transmitted to the receiver @7 on the controlled device 9 side and displayed on the display 2.

By the way, in the remote control system as described above, the display device 2 is provided on the side of the controlled device 9, so that it can be used to program reservations for television broadcasting, recording reservations for a video tape recorder, playback programs for a video disc player, or a computer. When setting a program consisting of multiple words that requires display, such as a program, if you set it from a remote location, it is difficult to confirm the settings.

The present invention has been made in view of the above-mentioned circumstances in conventional remote control systems, and is such that program data consisting of multiple word data such as recording reservation of a video tape recorder is displayed on a display means provided on the control device side. To provide a remote control system for transmitting multiple word data that is displayed all at once, allows the contents of each word data to be checked at a glance, and allows accurate and speedy program data setting work from a remote location from a control device. I am looking forward to it.

For this reason, the present invention sets program data such as a recording reservation for a videotape refugue consisting of a series of a plurality of word data on the control device side, and a remote controller that transmits the plurality of word data to be transmitted to a controlled device. In a control system, a control device is provided with a display means that displays program data all at once, the program data set on the display means is displayed all at once for confirmation, and the program data is sent all at once to a controlled device. It is characterized by

Embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

In FIG. 2, 11 is a control device, and in this embodiment, the display I2 and the data transmission button I3 are connected to the operating keyboard! 4. Provided on the control device 11 side together with the transmitter I5 and receiver 16.

On the other hand, the controlled device 19 side is provided with a receiver 17 and a transmitter 18 that perform bidirectional data transmission with the transmitter 15 and receiver I6.

In the above system, when a series of multiple word data is set using the operation keyboard 14, the word data is displayed on the display 12.

In the above state, after checking the display word data on the display 12,
By pressing the data transmission button I3, the transmitter! 5 transmits a data transmission start request signal.

The data transmission start request signal is received by the receiver 17 and sent to the controlled device 19, and the controlled device 19 transmits a data reception authorization signal from the transmitter I8.

When the receiver 16 receives the data reception authorization signal, the transmitter 15 of the control device 11 starts transmitting the plural word data.

Here, when the first word of the multiple word data to be transferred is transmitted from the transmitter 15 and received by the receiver 17, the controlled device 119 stores it in a memory (not shown) and transmits the first word. Control device 1 by machine 18
1 receiver 16.

The control device 11 receives data received by the receiver 16, and
of the multiple word data previously transmitted by the transmitter 15! The second word is compared, and if the two match, a data match detection signal is transmitted from the transmitter 15.

The receiver 17 on the controlled device 19 side receives the data coincidence detection signal, and the controlled device 19 recognizes the data previously stored in the memory as regular data, and issues a data transmission request requesting transmission of the next data. By transmitting the signal to the control device 11, data transmission of the l-th word is completed.

If data matching is not detected, data is transmitted again from the control device 11 side.

Transmission of a plurality of word data is completed by repeating the above operation for the number of words of the series of data.

As can be seen from the above, since the display 12 is provided on the control device 11 side, the transmitted word data can be easily confirmed.

Next, another embodiment of the present invention is shown in FIG.

The embodiment shown in FIG. 3 differs from the embodiment shown in FIG. 2 in that the receiver 16 on the control device 11 side and the transmitter 18 on the controlled device 19 are omitted, so compared to the system shown in FIG. This system is effective for systems with a small number of transmitted words.

In the embodiment shown in FIG. 3 above, by pressing the data transmission button 13 after setting the multi-word data to be transmitted using the operation keyboard 14, the multi-word data is encoded in the control device 11 and sent to the transmitter as one data. I am trying to transmit from I5.

In the embodiment shown in FIG. 3, in order to ensure the transmission operation, it is sufficient to add an error check code to the data hood or to transmit the transmission data multiple times.

As is clear from the detailed description above, according to the present invention, the set program data is displayed all at once on the display means provided on the control device side. When the data is composed of multiple word data, such as a recording reservation, the contents of each word data can be checked at a glance, and incorrect settings can be checked quickly and accurately, which is convenient.

Further, since the set program data can be confirmed and sent to the controlled device all at once, program data setting work can be performed accurately and quickly from a location away from the controlled device.
