Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to handy type wireless keyboards and
In remote control circuits for wireless remote control systems that support multiple functions and require complex operations, such as remote controllers for V-compatible systems, the main device is particularly susceptible to problems such as noise and transmission distance. The present invention relates to a remote control circuit with improved operability for re-instructing a life action when it is not executed.

[Conventional technology]

2. Description of the Related Art Remote controllers are increasingly being used as wireless remote controllers for personal combinators and other household electrical appliances. Furthermore, the Personal Combi 2-Y has great expectations in the future as an information terminal for general home use.

By the way, input devices for personal combiators for general home use are required to be easy to use, such as being easy for the operator to perform input operations and being operable from any position in the room.

A conventional example of a personal computer using a remote control will be explained below with reference to FIGS. 4 and 5.

FIG. 4 is a block diagram showing a remote control circuit of a conventional personal combinator, and FIG. 5 is a diagram showing the state of signal codes of each part.

In the figure, (capital) is the remote control, 31 is the operation input section,
32 is the transmission control circuit, oh is the transmission circuit, ah is the main device, 35
36 is a reception circuit, 37 is an operating section, wings are a motion detection circuit, 39 and 41 are display circuits, and 40 is an operation detection circuit.

The operation input section 31 outputs a predetermined digitally encoded operation signal by selectively operating the main device 34, such as a personal computer, in accordance with each operating function. FIG. 5a shows an example of an output 8-bit operation signal. This operation signal is then input to the transmission control circuit 32. The transmission control circuit wing includes a transmission circuit 33 and an operation detection circuit 40.
is connected.

Based on the input operation signal, this transmission control circuit 32 generates a 16-bit operation signal consisting of an operation signal as shown in FIG.
In addition to generating a bit data code, a 16-bit custom code consisting of a limited code and an inverted limited code to prevent interference with signals from other devices is also generated. The non-inverted code and the inverted code are compared and judged by the main unit 34, and when the respective codes are the corresponding codes, they are provided to prevent malfunctions to enable subsequent operations. The 16-bit custom code and data code are combined into 32 bits and input to the transmitting circuit 33 as an operation data signal. At this time, an input operation signal is sent from the transmission control circuit 32 via the operation detection circuit 40, and the display circuit 41 displays the contents of the operation. Then, the transmitting circuit 33 emits an infrared light operation command signal based on the input operation data signal, and transmits it to the main equipment R34. The receiving circuit 35 of the main device detects an operation command signal of infrared light transmitted from the remote controller 30 using a light receiving element. The operation command signal detected by the light receiving element is outputted from the reception circuit as a code having the same content as the operation data signal, inputted to the reception control circuit 36, and subjected to malfunction prevention processing as follows.

The limited code of the custom code and the inverted limited code are added, and it is determined whether all 8 bits are "1". As a result of the addition, if "O" is detected in at least one bit, no further operation is performed. Then, when all bits are "1", the limited code is compared with the limited code set in advance in the main system #A, and if they match, then the data code is subjected to malfunction prevention processing in the same way as the custom code. If it is normal, the operation signal will be decoded. Here, if an abnormality is detected and the process is interrupted midway, the system is reset by a command signal that is input again and the same process is performed.

The decoded operation signal is outputted from the reception control circuit 36 to the operation section J based on the content of the operation signal, and the operation section 37 performs the operation selected by the remote control 30. Further, the operating state of the operating section 37 is converted into a display signal via the operation detection circuit blade, and displayed on the display circuit 39.

[Problem that the invention seeks to solve]

However, the conventional remote control circuit as described above has the following problems.

That is, depending on the operating position, the receiving condition may become unstable in terms of transmission distance or infrared noise, and the signal may not be correctly transmitted to the main device and error processing may occur. In such a case, the operator must repeat the command and issue the command again, but if the command requires multiple operations, the operator must check the main unit to determine which operation resulted in an error. It is necessary to look and compare the display of the remote control with the display of the remote control, which impairs the operability when making corrections, and is difficult to apply to equipment that requires a large number of commands. allows the operator to quickly check the reception status of the commanded signal even for complex movement commands.
A technical problem is to provide a remote control circuit with improved corrective operation when a reception error occurs.

[Means for solving problems]

In order to solve the above technical problem, the present invention includes an operation input section 2 that outputs an operation signal a, a first storage circuit 6 that stores the operation signal a, and generates a light signal based on the operation signal a. A transmitter 18 that transmits a signal; a receiver 19 that receives a signal from the transmitter 18 in a first receiver circuit 8 and stores it in a second storage circuit; A reply unit 20 transmits an optical signal to the receiving circuit 15 of the second receiving circuit 15, and compares the signal received by the second receiving circuit 15 with the signal stored in the first memory circuit 6, and if they match, the second memory A signal for operating the actuating device 11 based on the signal stored in the circuit is output to the transmitter 18, and when they do not match, a signal is displayed for displaying the content stored in the first storage circuit 6 as an error. The instruction control circuit 4 outputs an output to the section 17.

[Effect]

The above technical means works as follows.

The signal received by the main device 7 is transmitted to the command control circuit 4 of the remote control 1.
It is compared with the operation signal a stored in the transmitting section 18, and if the contents match, a signal for operating the actuating device 11 of the main device 7 is output to the transmitting section 18, and when they do not match, the content of the error is displayed on the display section 17. Outputs a signal to display. Then, as soon as the operator confirms the location of the error displayed on the display section 17 of the remote controller 1, he or she will perform the operation again.

The operation signal a is once stored in the storage circuit 6, and is not output from the transmission control circuit 3 to the storage circuit 6 until the transmission control circuit 3 is reset.

Furthermore, when the transmission control circuit 3 receives the feedback signal C from the command control circuit 4, it performs the following operations regardless of whether the operation signal a is input.

First, when the feedback signal C is a data code for executing the operation of the 8-bit main device 7 shown in the second row, the 16-bit operation data signal shown in the figure is output from the transmission control circuit 3. and the main device 7 via the transmitting circuit 5.

The motion detection circuit 12 outputs a signal e as an 8-bit data code as shown in FIG. 2 e1 to the transmission control circuit 13 based on the signal input from the operating device 11.

The transmission control circuit 13 performs the following operations based on signals input from the reception control circuit 9 and the operation detection circuit 12 of the reception section 19.

First, when the signal from the reception control circuit 9 is input to the transmission control circuit 13, the "l" and rOJ of the custom code section are inverted as shown in @22 duplication regardless of the signal e from the operation detection circuit 12. The data is then output to the transmitting circuit 14 together with the data code section.

On the other hand, when there is no signal from the reception control circuit 9, the transmission control circuit 13 operates as follows using the signal e input from the operation detection circuit 12. When an 8-bit data code as shown in FIG. 2e is input to the transmission control circuit 13, the operating device 1
