[Prior Art] So-called wireless transmission control systems that wirelessly operate chimes and emergency receivers by transmitting weak radio waves have recently been widely used in homes and offices. Transmission data sent from a wireless transmitter is attached with a house code (ID code) that defines the channel, and the wireless receiver that received the transmission data confirms that the house code matches. , consideration is usually taken to prevent interference with other wireless systems.

17 and 18 show how to set a house code when such a wireless system is applied to a wireless chime. On the wireless transmitter 200 side, as shown in FIG. Operation switch 200

Depending on the purpose, a plurality of wireless receivers B may be combined with a plurality of wireless transmitters.

Next, the basic operation of the system of the present invention will be explained.

When the start switch 24a is operated, the internal circuit of the wireless receiver B is powered on, the timer control circuit section 27 is activated, and the mode indicator light 28 blinks to display the registration mode. Note that when the receiver is powered on, the mode indicator light 28 is dimly lit to indicate energization, unlike the mode indicator light 28 that is lit during operation.

When the registration mode is set in this manner, all data such as ID codes registered in the system data registration means 22 (#t) to (#n) are cleared (cold star 1.).

Then, depending on the control group of receiver B, sensor O
Operate the N/OFF setting switch 31 to set the sensor to O.
After setting the N and OFF signals, press the group selection switch 24. When you operate the call switch Ia of one of the wireless transmitters A that constitutes the registration by operating b, the antenna for that wireless transmitter outputs transmission data including the ID code in the form of a radio signal. This radio wave signal is captured by the antenna 2a of the receiver B, demodulated by the front end/decoder section 20, and transmitted data with an ID code is extracted.

The ID code extracted in this manner is registered in the data table constituting the designated system data registration means 22, and is included in the transmission data transmitted from any wireless transmitter A in this manner. When the ID code is registered in the designated system data registration means 22, the timer of the timer control circuit section 27 described above is activated, and the time T until the activated timer times up is determined by the wireless transmitter A. Sent ID
System data registration means 22 in which codes are specified one after another
will be registered.

Note that registration in the system data table is done using the same I
If a D code is received, subsequently received ID codes are ignored.

When the timer of the timer control circuit section 27 times up, the registration mode is switched to the normal control mode, and the mode indicator light 28 changes from blinking to lighting.

FIG. 7 shows the operation in the registration mode in this case with a flowchart, and FIGS. 8a) to 8d) show the operation in the registration mode with a time chart.

An outline of the operation of the system of the present invention will be explained based on FIG. 7. Even if the star j switch 24a is turned on, the front end/decoder section 20 confirms the reception of the transmitted data from the wireless transmitter A, and then sends the ID. The timer of the timer control circuit 27 is not activated until the :2-code is registered in the designated system data registration means 22, and the timer is activated only after this registration is confirmed.

When the activated timer times up after the set time T has elapsed, the timer is reset, the mode indicator light 28 lights up, the mode shifts to the control mode, and the wireless transmitter A
When the ID code of the transmitted data matches the ID code registered in the system data registration means 22, a control signal is sent from the data discrimination/control means 25 to the corresponding control object and remote control is performed.

In FIG. 8, a) shows the operation of the start switch 24a, and b) shows the reset signal output by operating the start switch 24a. This reset signal is input to the CPU constituting the control section of the receiver B. Then, all data registered in the system data registration means 22 are cleared all at once (cold start).

C) is the registration mode time period, d) is the wireless transmitter A
This shows the ID code sent from. Even if the start switch 24 & is turned on, unless any ID code is registered to the wireless transmitter,
It can be seen that the timer of the timer control circuit section 27 is not activated and maintains the registration mode, and shifts to the normal control mode only after the timer times out.

This example shows a so-called cold start mode in which all data registered in the system data registration means 22 is cleared when the start switch 24a is operated, but it may be configured such that additional data is registered.

FIG. 16 shows the configuration of the transmitting circuit section oscillation circuit section included in the transmitting control circuit.

The wireless transmitter 10B has a configuration including an oscillation circuit 101, a frequency multiplier 102, and a loop antenna 10a. In the figure, Ql is a transistor of a crystal oscillation circuit, and this transistor Q1 is a resistor in terms of direct current. R
1 and R2, and DC negative feedback is applied by resistor R3.

The oscillation circuit 101 also includes a crystal oscillator X, coils L, 1
．． It is configured to oscillate at a frequency determined by the capacitor Ct, but in order to maintain stability of the oscillation operation, the amount of positive feedback is determined by capacitor C2, and the amount of negative feedback is determined by capacitors C3, C4, and coil L2 to maintain stability. This ensures that oscillation is maintained.

The output of the oscillation circuit 101 is passed through the capacitor C6.
Coil L3. The harmonics of the frequency of the resonant circuit formed by capacitor C7 are selectively amplified, supplied to loop antenna loa through capacitors C8 and CjO, and radiated as a radio signal.

Here, the parallel resonant circuit formed by the capacitor C9 and the coil L4 is tuned to the target oscillation frequency, and has a low impedance for other frequencies.
It acts as a filter to remove interference waves.

Further, the capacitor C1l connected to the loop antenna 10a is provided to improve the radiation efficiency of the antenna together with the inductance component of the loop antenna 10a.

When forming such an oscillation circuit section on one side of a circuit board, it is desirable to form a conductive shield with a conductive plate pasted on the back side of the circuit board except for the part corresponding to the loop antenna 10a. , something like this:
The high-frequency magnetic field generated by the high-frequency waves generated by the oscillation circuit induces eddy currents in the conductive plate, and a magnetic field is generated that attempts to block this eddy current, so the incoming magnetic field is canceled out and attenuated, eliminating interference from disturbance waves. I can do it.
