Abstract

PURPOSE:To make a display on a display section of a transmitter match with the control state of a receiver by sending a control data again starting the load control operation at lapse of a prescribed time when the control data to start the load control operation is sent after lapse of a prescribed time. CONSTITUTION:When a control data is sent from a transmitter 1 to start control of a load after lapse of a prescribed time, the control data to start the load control is sent again after lapse of a prescribed time by a timer 15. Thus, even when a timer 25 of a receiver 2 is delayed, since the receiver starts the load control when the control data is received by the transmission of the control data representing the start of the load control from the transmitter, the display of the end of the timer 15 on a display section 16 of the transmitter is made match with the load control by the receiver.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wireless remote control device that transmits and receives wireless signals to perform control and notification.

[Conventional technology]

Generally, a wireless remote control device has one
It consists of one transmitter 1 and a plurality of receivers 2. Transmitter 1
As shown in FIG. 4, it consists of an operating section 11, a control section 12, a transmitting circuit 13, and an antenna 14. The operation unit 11 is provided with an operation button, and when a person operates the operation button, an operation signal is sent to the control unit 12. Control part 1
2, generating control data based on the operation signal;
It is sent to the transmitting circuit 13. The transmission circuit 13 modulates and amplifies the control data, and sends it into space as a wireless signal via the antenna 14.

The receiver 2 includes an antenna 21, a receiving circuit 22, a control section 23, and an output section 24, as shown in FIG. Control data sent from the transmitter 1 and transmitted through space as a radio signal is received by the antenna 21, amplified and demodulated by the receiving circuit 22, and input to the control unit 23.

The control section 23 generates a control signal based on the control data and inputs it to the output section 25 . The output unit 25 performs controls such as notifying and displaying the contents of the control data, or controlling the load according to the contents of the control data.

[Problem to be solved by the invention]

By the way, in such a wireless remote control system, if the transmitter/receiver 1 and 2 are each provided with a timer function, and the transmitter 1 is further provided with a function to display the time measured by the timer, the following will occur. There is a problem. That is, for example, when the transmitter 1 sends out control data that causes the load to stop operating after a predetermined period of time has elapsed, that is, to stop the output of the receiver 2, the transmitter 1 sends out the control data. At the same time, the time elapsed by the own timer is displayed on the display section, and when a predetermined period of time has elapsed, a message "Timer Ended" is displayed as shown in FIG. On the other hand, the receiver 2 operates its own timer according to the control data from the transmitter 1, and stops the output from the output unit 24 after a predetermined period of time has elapsed.

However, since the transmitter 1 and the receiver 2 use different timers, due to differences in the accuracy of each timer, the timer of the transmitter 1 does not use the timer of the receiver 2 even though the predetermined time has elapsed.
With the timer, it may happen that the predetermined time has not yet reached. Therefore, in this case, although the display section of the transmitter 1 shows that the "timer has ended", that is, the output of the output section of the receiver 2 has stopped, in reality, the display section of the receiver 2 This means that the output of the transmitter 1 has not stopped yet, and there is a problem in that the display of the transmitter 1 and the load control state by the receiver are different.

The present invention has been made in view of the above points, and its object is to provide a wireless remote control device that matches the display on the display of a transmitter and the control state of a load by a receiver. Our goal is to provide the following.

[Means to solve the problem]

According to claim 1, the present invention provides a wireless remote control device comprising a transmitter that transmits control data as a wireless signal, and a receiver that controls a load using the control data.
The transmitter and the receiver each include a timer, the transmitter further includes a display unit that displays time information measured by the timer, and the transmitter controls the load by the receiver after a predetermined period of time has elapsed. The present invention is characterized in that when control data for starting an operation is transmitted, control data for starting the load control operation is transmitted when the predetermined time has elapsed.

In claim 2, in the wireless remote control device of claim 1, when control data is transmitted from the transmitter to start a load control operation after a predetermined time has elapsed, the receiver is configured to The present invention is also characterized in that the load control operation is started after a long period of time has elapsed.

[Effect]

In claim 1, the wireless remote control device of the present invention includes:
When the transmitter transmits control data for starting a load control operation after a predetermined time has elapsed, the control data for starting the load control operation is transmitted again at the elapse of the predetermined time. Even if the timer on the receiver side is delayed, the transmitter sends control data indicating the start of load control operation, and the receiver starts load control as soon as it receives this control data. The timer expiration indication at the transmitter and the load control at the receiver coincide.

Furthermore, in claim 2, the receiver starts the load control operation after a time period longer than the predetermined time, so that even if the timer on the receiver side runs out, This prevents the receiver from starting load control before the transmitter's timer is indicated as expiring.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. Since the basic configuration of the wireless remote control device is the same as that shown in FIG. 4, the same parts are given the same numbers and the explanation will be omitted.

FIG. 1 is a block diagram showing one embodiment of the present invention.

15 is a timer built in the transmitter 1, and the control unit 12
Measures time up to a predetermined time using control signals from
The measured time is output to the control section 12. Reference numeral 16 denotes a display section provided in the transmitter 1, which displays the measurement time status by the timer 15, the load control status by the receiver 2, etc.

25 is a timer built in the receiver 2, which measures time up to a predetermined time using a control signal output from the control unit 23 in response to control data from the transmitter 1, and transmits the measured time to the control unit 23. Output.

Here, when the transmitter 1 transmits control data that causes the load control operation to start after a predetermined period of time has elapsed,
When the predetermined time has elapsed, control data indicating the start of the load control operation is transmitted again.

Next, the operation of this embodiment will be explained. FIG. 2 is a time chart showing the operation of this embodiment. FIG. 2(a) is the end timing of the timer 15 of the transmitter 1, and FIG. 2(b) is the control data output from the transmitter 1. , FIG. 2(C) shows the output signal of the output section 24 of the receiver 2 when received without error, and FIG. 2(d) shows the end timing of the timer 25 of the receiver 2. Now, let us consider a case where the operation of the load is to be stopped after L hours from the current point in time. First, the operation section 11
Input control data to stop the load after the time . The control unit 12 sets the timer 15 to time t, starts time measurement, and transmits the control data to the receiver 2 via the transmission circuit 13 and antenna 14. Further, the control unit 12 causes the display unit 16 to display the time measured by the timer 15.

In the receiver 2, the antenna 21 and the receiving circuit 22 receive the control data, and the control unit 23 sets the timer 25 to time t to start time measurement. In the transmitter 1, when the timer 15 finishes measuring the time t, the display unit 16 displays a message indicating that the timer has finished, and the display shown in FIG. 2(b)
The control data CD for stopping the load, as in
Send n frames continuously. The purpose of continuously transmitting n frames is to prevent reception errors in the receiver 2. In the receiver 2, the end timing of the timer 25 is as shown in FIG.
As shown in d), even if there is a delay of ΔL, by receiving the control data CD, there will be almost no delay from the end of the timer 15 of the transmitter 1, as shown in FIG. 2(C). Then, an output signal can be outputted from the output section 24 to stop the operation of the load. Note that even if the receiver 2 is unable to receive all n frames of control data CD from the transmitter 1 due to an error, the load can be reliably stopped at the timing when the timer of the receiver 2 ends.

In the above embodiment, the timing at which the time measurement of the timer 25 of the receiver 2 ends is later than the end timing of the timer 15 of the transmitter 1. If the timer has advanced, the display section 16 of the transmitter 1 indicates that the timer has not ended, but the output section 24 of the receiver 2 outputs an output, indicating that the load has stopped. things happen. In order to solve this inconvenience, the time setting of the timer 25 of the receiver 2 is changed to
It is sufficient to make the time longer than the time setting of the timer 15 of the transmitter 1. The extent of this lengthening time is determined by the timer 25.
It is sufficient to make the setting time longer than the time it would take if the time was measured. By doing this, even if the time measurement of the timer 25 of the receiver 2 progresses, the timer 1 of the transmitter 1
Since the end timing of the timer 25 of the receiver 2 is still later than the end timing of the timer 5,
The above inconvenience will not occur.

[Effects of the Invention] As described above, according to the wireless remote control device of the present invention,
In claim 1, when the transmitter transmits control data that causes the load control operation to start after a predetermined time has elapsed, the control data that causes the load control operation to start is transmitted again at the elapse of the predetermined time. Even if the timer on the receiver side is delayed, the transmitter sends control data indicating the start of load control operation, and the receiver automatically adjusts the load as soon as it receives this control data. Since control starts, the timer end display on the transmitter matches the load control on the receiver, and the display on the transmitter display matches the load control status on the receiver. We were able to provide a wireless remote control device.

Furthermore, in claim 2, in the receiver, the load control operation is started after a time longer than the predetermined time has elapsed, so that even if the timer on the receiver side has advanced, the transmission This prevents the receiver from starting load control before the transmitter's timer ends, so even if the receiver's timer has advanced, the transmitter's display will not start to control the load. It has been possible to provide a wireless remote control device that matches the display and the load control status at the receiver.
