Abstract

PURPOSE:To reduce the wear of a battery by supplying a battery power to a drive control circuit only when a remote control signal from a transmitter is received. CONSTITUTION:A power supply circuit 14 is provided between a power terminal VDD of a reception control circuit 15 and a battery power supply 19. The power supply circuit 14 starts its operation when a reception circuit 13 receives a remote control signal and after a prescribed time, its operation is stopped and when a signal is received by the control circuit 15, the circuit 14 supplies power for a prescribed time only. The control circuit 15 discriminates the propriety of the reception signal inputted to an input terminal SDI and when the signal is a correct data, a relay drive signal is outputted from an output terminal RC to a chime drive circuit 17. Since the power supply to the control circuit 15 is reduced only at the reception of signal in this way, the wear of the battery is saved remarkably in comparison with the case of a conventional circuit.

Then, the operation of the appended embodiment will be explained.

However, when the switch (IC) is turned off, the transistor (4) is turned off, so the transmission control circuit (5)
No power supply voltage is applied to the power supply terminal (vDD) of the switch (IC), and the transmission control circuit (5) does not operate to output a pulse signal from the transmission output terminal (SDO).
By turning on, the transistor of the Mino J supply circuit (, 5) is turned on, and by turning on the transistor, the power supply terminal (V
DD), the internal circuit of the control circuit (5) is reset, and the start signal of the control circuit (5) is input from the delay circuit (4) after 15 m has passed since the switch (IC) was turned on. A high level star signal is input to the terminal (ST) for a period of 15 m5ec.

Then, with the start signal of +JiJkihachiireheru,
A pulse train of a predetermined transmission take internally modulated with 120 songs is output from the transmission output terminal (SDO) of the control circuit (5) at 151.
A pulse signal whose edges are repeated f'' twice in 1'l5 is output, and the 1JiJ pulse signal is detected by the detection circuit (7) and transmitted to the transmitting circuit (8).l51nSeC includes two transmission takes repeatedly. C. The remote control signal is transmitted, the remote control signal is output from the transmitting antenna (9), and the remote control signal described in I'iJ is received by the receiving circuit (埒) via the receiving antenna (1'4). , as shown in FIG. 5(a), similarly to the remote control signal, l51'n5
A received signal that repeatedly includes the same reception take as the two transmission takes is output to eC, and the received signal is input to the receiving side power supply circuit 04) and the control circuit (5).

At this time, current from the battery (1!) flows through the battery (into the container when 191 is set) to one input terminal of the OR gate (26), and the OR gate t-(26+
Since a high-level reset signal is input to the reset terminal (R) of the DFF (22), I) F Ii' (221) is reset six times before the received signal.

Next, by the human power of the received signal "l-+1", as shown in FIG.
As shown in b), the clock terminal (CK
) input time 1. It's hot at the same time as l D F F (
The Q output terminal (Q) of 221 is at low level 1. By inverting the Q output terminal (Q) to H, the content (24) is charged, and the transistor (outside the transistor) is activated, and the received signal is Based on the input to the reception input terminal (SDI), the control circuit 051 determines whether or not the reception take included in the input reception signal is a correct take. ), after the output of the 11J reception number, a high level relay drive is applied from the output terminal (ILC) of the control circuit 0■ to the chime drive circuit α!

- The coil is excited and the relay contact turns on, as shown in the same figure (r).
As shown in , when the relay contact is turned on, the chime is energized and the chime sounds.

At this time, if the control circuit is 0, it will remain for a while after the power is turned on!
Because the operation is unstable, the control circuit q (g) does not determine whether the e-value data included in the input received signal is correct data during that time, but the receive take is performed twice. As the process is repeated, the operation of the control circuit (1) eventually becomes stable, and while the second take is repeated, it is determined whether the received data is a correct take or not.

Then, by charging the content (24), the content (

151 stops operating, and as shown in the same figure (e), the output of the /S irregular relay drive control signal from the output terminal (aC) stops, and the excitation of the relay coil I stops. As shown in FIG.
Therefore, according to the embodiment described in ff1iJ, the transmitter (1
) can only supply power to the control circuit (old battery (one)), which can greatly reduce the consumption of the battery (19), which is very practical and Economical.

Also, on the transmitter (1) side, battery power is supplied to the control circuit (5) only when the switch (IC) is turned on, so battery consumption on the transmitter (1) side can be significantly reduced. I can do it.

Note that the control circuits (5) and Q■ may have other circuit configurations or may be constructed from other LSTs.

Of course, the present invention can be applied to systems other than the seat control type team.
