Abstract

PURPOSE:To receive no undesired signal when the signals are congested on a transmission line and to save the electric power with a receiving device which receives a signal containing a transmitting address identification code. CONSTITUTION:The transmitting address identification code of the signal received by a receiving means 4 is detected by an address detecting means 8. Then a reception deciding means 6 decides the signal addressed to its own from the output of the means 8 and the stored contents of a self-identification code storage means 7. The means 6 reports the coincidence if secured between the transmitting address identification code detected by the means 8 and the self-identification code stored in the means 7 to a reception inhibiting means 11 which inhibits the receiving action of the means 4 for a prescribed period. When the means 11 knows a fact that a signal is received by a receiving device 10 from the means 6, the means 11 inhibits the receiving action of the means 4 for a prescribed period and therefore shortens the operating time of the means 4.

The remote control device sends the set temperature to the water heater main body to supply hot water. The hot water supply temperature of the machine body is changed, the hot water supply machine body transmits the hot water discharge temperature as a monitor signal to the remote control device, and the remote control device receives the monitor signal and displays the hot water discharge temperature. Less than,
The configuration will be described with reference to FIG.

As shown in the figure, a remote control device 1 as a receiving device has a receiving means 4 for receiving a signal from a water heater main body 2 via a transmission path 3 and a signal processing for processing the received signal. The means 5, the reception confirming means 6 that permits the signal processing means 5 to process the received signal, the self-identification code storage means 7 that stores the self-identification code, and the destination identification code of the signal received by the reception means 4 The reception confirmation means 6 is composed of a destination detection means 8 for detecting and a display means 9 for displaying. The reception confirmation means 6 stores the destination identification code detected by the destination detection means 8 in the self-identification code storage means 7. When it coincides with the self-identification code, the signal processing means 5 notifies the signal processing means 5 of the received hot water temperature on the display means 9 as shown in FIG.

[0005]

In the conventional structure as described above, the receiving means 4 receives the monitor signal from the water heater main body 2, and therefore must always receive the signal.
When a battery is used as the power source, there is a problem that the power consumption increases and the life of the battery shortens. For this reason, as a receiving device using a battery, a method is adopted in which the presence or absence of a signal is checked at regular intervals, and if there is a signal, reception is performed, but even if the presence or absence of a signal is intermittently checked, reception is performed. Even if there is a signal on the transmission line 3,
During that time, it is necessary to perform reception so long as the signal on the transmission path 3 such as a wire or infrared light is relatively limited, but the signal on the transmission path 3 such as a radio wave is not limited, and congestion is caused. When it is easy to do so, signals are received one after another, and it is difficult to obtain the effect of measures for extending the battery life.

An object of the present invention is to solve the above problems, and an object thereof is to provide a receiving apparatus capable of saving power without receiving an unnecessary signal when a signal on a transmission line is congested. ..

[0007]

In order to achieve the above object, the present invention has a receiving means for receiving a signal, and a reception confirming means for judging that the signal received by the receiving means is a signal addressed to itself. A self-identification code storage means for storing a self-identification code, which is the self-identification code, a destination detection means for detecting a destination identification code of a signal received by the receiving means, and a receiving means for a predetermined period. And a reception prohibition means for prohibiting reception of the reception identification means, wherein the reception confirmation means matches the destination identification code detected by the destination detection means with the self-identification code stored in the self-identification code storage means. In this case, the reception prohibiting means is informed, and when the reception prohibiting means is informed of the reception to the receiving device from the reception confirming means, the reception by the receiving means is predetermined. The that be prohibited time is set to the first means for solving problems.

Further, the reception prohibiting means of the first problem solving means, during the signal length of the signal to be transmitted / received when the reception confirming means informs the reception device,
The second problem solving means is that the reception by the receiving means is prohibited.

Further, the reception prohibiting means of the first problem solving means, when the reception confirming means informs that there is a reception to this receiving device, the reception prohibiting means operates for a time equal to the transmission prohibiting time of the transmitting device. The third problem solving means is that reception is prohibited.

[0010]

According to the first means for solving the above problems, the present invention provides:
When the receiving means receives the signal, the destination detecting means detects the transmission destination identification code of the signal received by the receiving means and transmits it to the reception confirming means. Upon receiving the transmission destination identification code of the signal received from the destination detection means, the reception confirmation means compares it with the self-identification code stored in the self-identification code storage means. Communicate the reception. Accordingly, the reception prohibiting means prohibits the reception means from receiving a signal for a certain period of time and stops receiving other signals.

Further, according to the second means for solving the problems, even when the transmission signals are transmitted one after another on the transmission line, it is possible to eliminate the reception of the extra signal transmitted immediately after the reception.

Further, according to the third problem solving means, by prohibiting the receiving operation after receiving the signal at the transmission prohibited time, the reception time can be shortened without failing to receive the signal from the transmitter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 1 for a remote controller for a water heater as in the conventional example. The same components as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 1, the remote control device 10 comprises a reception prohibiting means 11, and the reception confirming means 6 is stored in the transmission destination identification code detected by the destination detecting means 8 and the self-identification code storing means 7. If the received self-identification code matches, the reception prohibition means 11 is notified and the reception prohibition means 1
When the reception confirmation means 6 informs the remote control device 10 of the reception, the reception means 4 prohibits the reception by the reception means 4 for one signal length. 12a, 1
2b is a hot water outlet temperature setting device, which is connected to the transmission path 3.

The operation of the above structure will be described with reference to FIG. 2. When the hot water outlet temperature of the water heater main body 2 is changed by the hot water outlet temperature setting means 12a (FIG. 2 (A) -a),
Hot water temperature setting means 12a transmits the data of the set temperature to the water heater body 2 (FIG. 2 (A) -b). Although the remote control device 10 performs reception (FIG. 2 (E) -c), since the destination identification code detected by the destination detection means 8 is different, the reception confirmation means 6 does not confirm the signal reception. On the other hand, since the destination identification code of the water heater main body 2 is the self-identification code of the water heater main body 2, this signal is processed to change the hot water temperature (FIG. 2 (C) -d), and the remote controller 10 is operated. The outlet heated water temperature is transmitted to the destination (FIG. 2 (C) -e).

In the signal sent from the water heater main body 2 to the remote controller 10, the destination identification code is the remote controller 10.
Since it is the self-identification code of No. 2, when it is received by the receiving means 4 (FIG. 2E-f), the destination identification code detected by the destination detecting means 8 is stored in the self-identifying code storage means 7. Since it is equal to the self-identification code, the reception confirming means 6 confirms the reception of the signal, and the signal processing means 5 displays the outlet heated water temperature data of the received signal on the display means 9 (FIG. 2).
Along with (D) -g), the reception prohibition means 11 prohibits reception by the reception means 4 for one signal length (FIG. 2 (E) -h).

Next, when there is another hot water temperature setting device 12b waiting for transmission while the hot water temperature setting device 12a and the hot water heater body 2 are transmitting (FIG. 2 (B) -i), When the transmission is completed and the transmission path 3 becomes free, the hot water outlet temperature setting device 12b transmits the hot water to the main body 2 of the water heater (FIG.
j). The water heater main body 2 similarly receives this signal (Fig. 2 (C) -k) and changes the hot water temperature (Fig. 2 (C)-
l), the hot water outlet temperature is transmitted to the remote control device 10 (FIG. 2).
(C) -m), since the remote control device 10 receives the signal from the water heater main body 2 and the reception prohibiting means 11 prohibits the receiving operation for one signal length ((E) in FIG. 2). ) -H),
It does not receive the signal from the hot water temperature setting device 12b, but only the signal of the hot water temperature from the hot water heater body 2 thereafter (FIG. 2 (E) -n).

As described above, according to this embodiment, since the signal is not received for a certain period of time after receiving the signal from the water heater main body 2, unnecessary signal reception can be avoided and power consumption can be saved.

Next, another embodiment of the present invention will be described with reference to FIG. The same components as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted.

As shown in the figure, the transmitting device 13 transmits a signal from the water heater main body or the hot water outlet temperature setting device of the above-mentioned embodiment, and the transmitting means 14 and the transmission prohibition time timing for measuring a predetermined time. It has a means 15 and has a transmission prohibition time of a predetermined time after data transmission as in the case of communication with a specific low power, and transmits to the remote control device 16 via the transmission path 3. ..

The operation of the above-mentioned configuration will be described with reference to FIG. 4. The transmitting device 13 is as shown in FIG.
When the data is transmitted from the transmitting means 14, the transmission prohibition time measuring means 15 measures a predetermined transmission prohibition time t0, and the transmitting means 14 transmits the data until the transmission prohibition time measuring means 15 finishes the time measurement. It is prohibited. When the remote control device 16 receives the signal from the transmission device 13 as shown in FIG. 4B, the reception confirmation means 6 confirms the reception of the signal as shown in FIG. Processing means 5
Processes the received signal. On the other hand, the reception prohibition means 11
Prohibits reception by the receiving means 4 during the transmission prohibition time t0 as shown in FIG. 4 (D). When the transmission is completed, the transmission device 13 is prohibited from transmitting during the transmission prohibition time thereafter.
Even if it becomes necessary to transmit data immediately after transmission, the data is transmitted after the transmission prohibition time has elapsed. On the other hand, the remote controller 16
Receives the signal from the previous transmitter 13 and the reception prohibition means 11 prohibits the reception operation during the transmission prohibition time. Therefore, when the reception is started after the transmission prohibition time, the transmission is started at the same time. The signal from the transmitting device 13 is received.

As described above, according to this embodiment, the transmitter 1
After receiving the signal from No. 3, the remote control device 16 does not perform reception during the transmission prohibition time of the transmission device 13, so that a necessary signal is not missed and an unnecessary signal reception is avoided.
Electric power can be saved.
