DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an overall view of an industrial radio control system using an industrial radio control receiver of the present invention. In this figure, the radio control transmitter 1 has a transmission button 1-1 for channel 1 (CH1), a transmission button 1-2 for channel 2 (CH2), and a transmission button 1- for channel 3 (CH3).
3 is provided. These send buttons 1-1 to 1-
When one of the transmission buttons 3 is operated, a radio wave is transmitted from the transmission antenna 2 of the radio control transmitter 1. This radio wave is a weak radio wave system, and its frequency is, for example, about 304M.
The transmission antenna 2 is built in the small radio-controlled transmitter 1.

Further, the industrial radio control receiver 10 has a receiving antenna 3 for receiving the radio wave transmitted from the transmitter 1, a high frequency circuit 4 for amplifying / detecting the received radio wave, and a decoder circuit 5 for demodulating a modulated signal. And an operation setting dip switch 6 for setting the operation mode of the decoder circuit 5, and an output circuit 7 for outputting ON / OFF control outputs of CH1 to CH3 of the momentary operation or the latch operation.

The operation of the industrial radio-controlled device thus configured will be described. CH1 to CH3 of radio control transmitter 1
When the transmission buttons 1-1 to 1-3 are operated, the radio wave modulated by the modulation signal including at least the channel code of the operated channel is transmitted from the transmission antenna 2. This radio wave is the receiving antenna 3 of the radio control receiver 10.
When the signal is received at, it is amplified and detected by the high frequency circuit 4 and supplied to the decoder circuit 5. This decoder circuit 5 is set by the operation setting DIP switch 6 to determine whether each channel performs the momentary operation or the latch operation, and it is determined according to the code of the demodulated channel and the operation mode set by the DIP switch 6. The demodulated signal is output to the output circuit 7. The output circuit 7 receives the demodulated signal and outputs the output signals to the output terminals 7-1 to 7-3 of the respective channels.
The ON / OFF output control signal of the operation mode set by the DIP switch 6 is output.

The operation setting DIP switch 6 for setting the operation mode in the decoder circuit 5 is arranged on the substrate on which the receiving circuit is assembled, and a lid provided on a part of the housing of the radio control receiver 10 is used. The dip switch 6 can be changed and set by opening it, and the flow when the setting of the dip switch 6 is changed is shown in FIG. Figure 2
When the power of the radio control receiver 10 is turned on in step S100, the decoder circuit 5 determines in step S100 by software how the operation setting dip switch 6 is set. Set the output control operation to momentary operation or latch operation. The decoder circuit 5 may be composed of a microcomputer (CPU). When changing the setting of the DIP switch 6 in this way, after switching the DIP switch 6,
By turning on the power of the radio control receiver 10, the change setting is read and the change is performed.

Next, FIG. 3 shows an example of the structure of a modulation signal for modulating the radio wave transmitted from the radio-controlled transmitter 1. The modulation signal, as shown in FIG. 3, is a synchronization signal (Sync) for synchronizing the radio control receiver 10 with the radio wave transmitted from the radio control transmitter 1, and a CH indicating which channel is the on / off control signal. Code and radio controlled device ID
It is composed of a code and an error detection code for preventing malfunction. The radio control transmitter 1 has a send button 1-1.
While 1-3 are operated, the modulated signal having the configuration shown in FIG. 3 is repeatedly transmitted.

Upon receiving the transmitted radio wave, the radio control receiver 10 recognizes that its own ON / OFF control signal has been received when the decoder circuit 5 detects its own ID code two or more times in succession, and CH1 When the channel code of CH3 is detected twice or more consecutively, it is recognized that the ON / OFF control signal of the detected channel is received. Then, the decoder circuit 5 is
The ON / OFF control signal is supplied to the output circuit 7 so that the output circuit 7 operates by the momentary operation or the latch operation set by the DIP switch 6. The output circuit 7 controls on / off of the recognized channel based on the supplied control signal.

An example of the operation of the decoder 5 and the output circuit 7 will be specifically described with reference to FIG. However, in this figure, it is assumed that CH1 to CH3 are set by the dip switch 6 so as to perform the latch operation.
As shown in FIG. 5A, when the radio button including the channel code information of CH1 is transmitted by operating the transmission button 1-1 of the radio control transmitter 1 at time t1, the decoder 5 detects the channel code of CH1. Therefore, the decoder 5 supplies the output circuit 7 with the control signal which is turned “on” at the time t1. In response to this, the output circuit 7 turns on the output of CH1 as shown in FIG.

Then, at time t2, when the transmission button 1-2 of the radio-controlled transmitter 1 is operated to transmit the radio wave including the channel code information of CH2, the channel code of CH2 is detected by the decoder 5. 5
Supplies a control signal for turning on CH2 to the output circuit 7 at time t2 and a control signal for turning off CH1 to the output circuit 7. In response to this, the output circuit 7 turns off the output of CH1 at time t2 at the time t2 as shown in FIG.
The output of H2 is turned "on" at time t2.

At time t3, when the radio button including the CH3 channel code information is transmitted by operating the transmission button 1-3 of the radio-controlled transmitter 1, the decoder 5 detects the CH3 channel code. At time t3, CH3 supplies a control signal for turning on CH3 to the output circuit 7, and supplies a control signal for turning off CH2 to the output circuit 7. In response to this, the output circuit 7 outputs the output of CH2 at time t3 as shown in FIG.
Is turned off at the same time, and the output of CH3 is turned on at time t3 as shown in FIG. To turn off the output of CH3, either of the send buttons 1-1 and 1-2 other than CH3 may be operated.

Next, another example of the operation of the decoder circuit 5 and the output circuit 7 will be specifically described with reference to FIG. However, in this figure, it is assumed that CH1 and CH3 are set to perform the latch operation, and that CH2 is set to the momentary operation by the dip switch 6. As shown in FIG. 6 (a), at time t4, the transmission button 1-1 of the radio-controlled transmitter 1 is operated to CH.
When the radio wave including the channel code information of 1 is transmitted, the channel code of CH1 is detected by the decoder 5, and therefore the decoder 5 supplies the control signal which is “on” at the time t4 to the output circuit 7. In response to this, the output circuit 7 turns on the output of CH1 as shown in FIG.

Subsequently, during a period of time t5 to t6, when the radio button including the channel code information of CH2 is transmitted by operating the transmission button 1-2 of the radio control transmitter 1, C
Since the channel code of H2 is detected by the decoder 5, the decoder 5 receives CH2 during the period from time t5 to time t6.
Supplies to the output circuit 7 a control signal that turns on, and supplies a control signal to the output circuit 7 so that CH1 turns off at time t5. In response to this, the output circuit 7 turns off the output of CH1 at time t5 as shown in (d) of the figure, and turns on the output of CH2 at t5 to t6 as shown in (e) of the figure. And

Further, at time t7, when the transmission button 1-3 of the radio-controlled transmitter 1 is operated to transmit the radio wave including the channel code information of CH3, the channel code of CH3 is detected by the decoder 5, so the decoder 5 supplies the output circuit 7 with a control signal for turning on CH3 at time t7. In response to this, the output circuit 7 turns on the output of CH3 at time t7 as shown in FIG. When turning off the output of CH3,
Any of the send buttons 1-1 and 1-2 other than CH3 may be operated. Further, the number of channels is not limited to 3 and may be 4 or more.

In addition to the operation described above, the industrial radio-controlled receiver of the present invention may turn off the outputs of all channels when two transmission buttons are simultaneously operated. It should be noted that the modulation signal for modulating the radio wave transmitted from the radio control transmitter 1 is the same in any of the operation modes of the momentary operation and the latch operation. In the above description, the operation mode is set by the DIP switch, but the present invention is not limited to this, and a switch such as a jumper switch may be used instead of the DIP switch.

As described above, the industrial radio control receiver of the present invention can easily set the operation mode by the DIP switch or the like without using a soldering iron or the like. Further, since radio waves are used as the transmission medium for the ON / OFF output control signal, it has the advantages that it has no directivity like an infrared remote control device and that it is less susceptible to obstacles in the middle of the transmission path.

[0027]

Since the industrial radio control receiver of the present invention is configured as described above, the operation mode of each channel can be freely set to either the momentary operation or the latch operation by the DIP switch. Eliminating the need to prepare multiple types of industrial radio control receivers in advance. Therefore, the production cost can be reduced and the quality control can be easily improved.
