Description

[Detailed description of the device]

[Field of Industrial Application] [0001] The present invention relates to a remote control device for industrial machinery and consumer equipment, or a data collection device such as a contact point / sensor.

[Prior Art] Conventionally, there has been a remote control device having a plurality of switches and performing an operation corresponding to a pressed switch.

[Problems to be solved by the invention] Since switches are coded and sent, when a plurality of switches are pressed at the same time, the pattern of the switches cannot be reproduced on the receiving side, and a plurality of operations are simultaneously performed. I couldn't do it. Also, I couldn't do it even if I tried to send the data of contacts and sensors. The present invention has been made to eliminate these drawbacks.

[Means for Solving the Problem] The inventor pondered how to solve the above-mentioned problems, and as a result, the transmitter side turned on and off the plurality of SW (1) states. Is input as a digital signal from the input interface circuit (2), and following the start data from the transmission start data generation circuit (3), the input data and its inverted data are transmitted to the transmission parallel-in serial-out shift register (4). It is characterized in that a plurality of operating parts can be simultaneously controlled by the number of a plurality of SW (1) by sequentially transmitting the data alternately.

[Operation] According to the present invention, a plurality of pieces of contact information input to the transmitting side can be completely reproduced on the receiving side of the remote control device.

[Embodiment] An embodiment shown in the drawings will be described in more detail below. On the transmission side of FIG. 1, the ON-OFF states of a plurality of SWs (1) are input to the data input from the input interface circuit (2) and its inverted data by the shift of the transmission parallel internal out shift register (4). Input to the register alternately. At the same time, the data to be the start mark of the start data generating circuit (3) for transmitting a series of waveform data is input. The shift register takes in the input data internally by the output of the counter (7), sequentially shifts it by the output of the transmission oscillation circuit (6), and outputs it to the transmission module (5). On the receiving side in FIG. 2, the output of the receiving module (8) is input to the receiving parallel in-serial-out shift register (11). In the receiving parallel in-serial-out shift register (11), the receiving oscillator circuit (10) is input. The output is sequentially shifted and output as parallel data. At this time, the reception synchronization circuit (9) controls the reception oscillation circuit (10) so that the data is normally shifted. The data output from the reception parallel-in serial-out shift register (11) is first detected by the start mark digital comparator (13) to detect the start mark. In the data string after the start mark, the input data after the start mark and its inversion data are output alternately, so the data returned together with the input data after the start mark and the inverted data by the inverter (14) are used for data. Input to the digital comparator (15). If the start mark is matched by the start mark digital comparator (13) and the input data after the start mark and the inverted data are matched by the data digital comparator (15), the AND gate (16) is used. Output a match signal. The output latch circuit (17) takes in the input data after the start mark internally by the coincidence signal from the AND gate (16) and outputs it to the output section of the output interface circuit (18).

The check points a to e in FIGS. 1 and 2 have waveforms as shown in FIGS. 3 and 4. Checkpoint a in FIG. 1 is the shift clock waveform of the transmission parallel-in serial-out shift register (4), and checkpoint b is the timing point at which the input data is loaded into the transmission parallel-in serial-out shift register (4). is there. Checkpoint d in FIG. 2 is the output waveform from the receiving module (8) when the input is FFFFh, and checkpoint e is the shift clock waveform from the receiving oscillator circuit (10). Checkpoint c1 in FIG. 3 is an output waveform from the transmission parallel internal out shift register (4) in the case of input FFFFh, and checkpoint c2 is the transmission parallel in serial out shift register (4) in the case of input A5A5h. ) Is an output waveform from.

As the transmitting module (5) and the receiving module (8), any module such as infrared ray / FM modulation can be used. Further, the circuit of this embodiment can be replaced with a microcomputer or the like. In addition, it can be used as a data collection device in a wide range of fields such as industrial machinery, consumer equipment, home appliances, housing / health appliances, and teaching materials.

[Advantages of the Invention] According to the present invention, even if a plurality of SWs (1) are pressed at the same time in a remote control device for industrial machinery and consumer equipment, the input pattern can be reproduced on the receiving side. The operating points can be controlled simultaneously. It can also be used as a data collection device for contacts and sensors, taking advantage of the fact that input data can be sent as it is.
