Abstract

PURPOSE:To surely generate the buzzer tone of a 2nd end terminal equipment through the input of a buzzer switch of a 1st terminal equipment by providing a buzzer switch and a 1st timer or the like to the 1st terminal equipment and a buzzer tone generating means or the like to the 2nd terminal equipment. CONSTITUTION:When a buzzer switch 14 of the 1st terminal equipment 1 is depressed, a control section 6 uses a transmission means 7 at first to send a buzzer ON signal and sets a 1st timer 17 to 300ms, which is started. When the timer 17 expires, the input of the switch 14 is confirmed and the similar operation is repeated till the switch 14 is released and a buzzer ON signal is sent to an interval of the timer 17 from the means 7. Then a reception means 8 in the 2nd terminal equipment receives a buzzer ON signal periodically at an interval of the timer 17 and a control section 9 decides it to raise the buzzer and starts a 2nd timer 18 and the buzzer ON signal is received till the timer 18 expires. Thus, the buzzer tone of the terminal equipment 2 is surely generated through the input of the switch 14 of the terminal equipment 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a remote control device for operating equipment.

Prior Art A conventional remote control device was constructed as shown in FIGS. 5 and 6. When the user of the first terminal calls attention to the user of the separated second terminal, the buzzer of the second terminal is sounded by turning on the buzzer switch of the first terminal. As shown in Fig. 5, when the buzzer switch of the first terminal is input, a buzzer ON signal is transmitted from the first terminal, and as shown in Fig. 6, the second terminal receives the buzzer ON signal from the first terminal. is received and a buzzer sound is generated.

When the buzzer switch of the first terminal is released, a buzzer OFF signal is transmitted from the first terminal, and the second terminal receives the buzzer OFF signal from the first terminal and stops the buzzer sound.

Problems to be Solved by the Invention However, the above configuration has the following problems.

(1) The second terminal generates a buzzer sound in response to the buzzer ON signal, so if it cannot be received normally, the second terminal will not be able to generate a buzzer sound even if the first terminal's buzzer switch is input. .

(2) Even if the second terminal normally receives the buzzer ON signal and generates a buzzer sound, the buzzer is turned off from the first terminal.
If the signal cannot be received normally, the second terminal will continue to buzz.

The present invention solves such conventional problems, and aims to provide a simple method that reliably generates a buzzer sound of a second terminal by inputting a buzzer switch of a first terminal.

Means for Solving the Problems In order to solve the above problems, the remote control device of the present invention is activated by the input of the buzzer switch 14, operation switches 15 and 16 that perform other functions, and the switches 14 and 15. a first timer that periodically overflows and restarts while the first timer is activated; and a first timer that transmits a corresponding signal to each of the switches 14, 15 each time the first timer is activated. a terminal, a receiving means 8 for receiving the buzzer ON signal, and the buzzer ON signal;
a second timer that is activated by a signal and overflows in a longer time than the first timer; and a second terminal that includes a buzzer sound generating means that generates a buzzer sound until the second timer overflows when activated. a receiving means 11 that receives a predetermined signal; a control section 12 that performs predetermined control based on a predetermined signal transmitted from the first terminal; a third terminal including a controlled section; The terminal includes a transmission means for transmitting signals between the terminal, the second terminal, and the third terminal.

Effect of the Invention With the above-described configuration, the present invention can reliably generate the buzzer sound of the second terminal while the buzzer switch of the first terminal is input.

Embodiment Hereinafter, a remote control device according to an embodiment of the present invention will be explained based on the accompanying drawings. In FIG. 1, l is a first terminal, 2 is a second terminal, 3 is a third terminal,
Each is connected by a signal transmission means 4. 1st
The terminal 1 is composed of an operation section 5, a control section 6, and a transmitting means 7. The second terminal 2 includes a receiving means 8, a control section 9, and a buzzer sound generating means 10. The third terminal 3 is composed of a receiving means 11, a control section 12, and a controlled n section 13. The operation section 5 includes a buzzer switch 14, an operation switch 15 having a self-repeat function (hereinafter referred to as a self-repeat switch), and other operation switches 16. The control unit 6 first includes timers 17, 11. A second timer 18 is built into the lllil section 9.

Next, the operation when the operation switch 16 of the first terminal is pressed will be explained with reference to FIGS. 1, 2, 3, and 4.

When operating a device normally, as shown in FIG. 2, by pressing the operating switch 16, the control section 6 determines the type of switch and controls the transmitting means 7 to transmit a predetermined signal. The transmitting means 7 transmits a predetermined signal to the third terminal 3 through the transmitting means 4. In the third terminal, as shown in FIG. 4, the receiving means 11 receives the signal, the control section 12 determines the signal, and controls the controlled section 13.

Next, a case where the self-repeat switch 15 is input will be explained. When the self-repeat switch 15 is pressed, the control unit 6 first causes the transmitting means 7 to transmit a signal (hereinafter referred to as a self-repeat signal) transmitted by a switch having a self-repeat function. At the same time, set the self-repeat timer (first timer 17) to 500 m5 and start it.If the self-repeat timer overflows, that is, after 500 m5, check the switch input. If the self-repeat switch 15 continues to be input, the self-repeat signal is retransmitted, the self-repeat timer is set to 300 m5, and restarted. Thereafter, the same operation is repeated until the self-repeat switch 15 is released. Through this operation, the transmitting means 7 transmits a self-repeat signal at the interval of the first timer 17. Since the third terminal 3 periodically receives the self-repeat signal, the control unit 12 determines the signal and sequentially updates the settings of the controlled unit 13.

Next, regarding the case where the user of the first terminal l wants to alert the user of the second terminal 2, in other words, by pressing the buzzer switch 14 of the first terminal operator, the buzzer sound of the second terminal 2 is activated. A case in which this occurs will be explained. As shown in FIG. 2, when the buzzer switch 14 is pressed, the transmitting means 7 causes the itIIIm section 6 to transmit a buzzer ON signal. At the same time, set the buzzer timer (first timer! 7) to 300 seconds and start it. If the buzzer timer overflows, check the input of the buzzer switch 14.

Thereafter, the same operation is repeated until the buzzer ON switch 14 is released. Through this operation, the buzzer ON signal is transmitted from the transmitting means 7 at the interval of the first timer 17.

In the second terminal 2, as shown in FIG. 3, the buzzer ON signal is periodically received from the receiving means 8 at the interval of the first timer 17 (300 ma). The control unit 9 determines the buzzer ON signal and starts the buzzer at the same time as the second timer 1B.
(500m5) Start.

It then waits to receive the next buzzer ON signal until the second timer 18 overflows. When the buzzer ON signal is received, the second timer 18 is restarted. Then, it waits to receive the next buzzer ON signal until the second timer 18 overflows again. 1st
When the buzzer switch 14 of the terminal l is released and the buzzer ON signal is no longer received, the second timer 18 overflows and stops the buzzer sound.

As described above, the buzzer sound of the second terminal 2 can be generated only while the buzzer switch 14 of the first terminal 1 is input. In this embodiment, the first terminal 1 and the second terminal 2 Since timers 17 and 18 are set to periodically send and receive buzzer ON signals, even if transmission is not possible, the buzzer sound will only be interrupted for a moment, and the user of the second terminal 2 is hardly recognized intuitively and poses no problem in practical use.Also, since the buzzer ON signal is transmitted periodically at fixed intervals, other signals can be transmitted between the buzzer ON signals. This is the same as before,
Furthermore, in this embodiment, since the buzzer timer set in the first terminal l is shared with the self-repeat timer, the first
A large amount of memory and execution time of the microcomputer normally used in the control unit 6 of the terminal l are not required, and the control unit 6 can execute other processes.

In the remote control device of this embodiment, the first timer 17 is set to 300+ms, and the second timer 18 is set to 500m5, but the time is not limited to these. 3 is assumed to be three, but it goes without saying that the number is not limited to this number.Also, the buzzer switch 14 of the first terminal 1 is input to generate the buzzer sound of the second terminal 2, but the buzzer Which terminal 1.2 is the switch 14 and the buzzer sound generating means lO connected to?
．． 3, there is no equivalent problem, and the operation section 5 and transmission means 7
, receiving means 8.11. The controlled unit 13 is connected to which terminal 1.2.
Needless to say, the same problem does not arise even if the terminals 1, 2, and 3 are used, and the transmission means 4 between the terminals 1, 2, and 3 may be of a wireless type or a wired type.

Effects of the Invention As described above, the remote control device of the present invention provides the following effects.

(1) Input the buzzer switch of the first terminal and
When generating a buzzer sound from a terminal, the buzzer ON signal and buzzer OFF signal are not transmitted separately, but the buzzer ON signal is transmitted periodically, so even if transmission is not possible normally, there will be no problem. A buzzer sound can be generated.

(2) Since the timer for the buzzer ON signal and the timer for self-repeat are shared, a large amount of memory and execution time of the microcomputer normally used in the control section of the terminal are not required.
