Abstract

PROBLEM TO BE SOLVED: To shorten time until transmission is started after a press switch is depressed and to dissolve or reduce the interruption of the state of speech, which occurs during transmission, by executing an inside starting processing and a transmission channel setting processing, detecting the on-state of the press switch and setting it in a transmission start state. SOLUTION: When a control circuit 26 detects that a touch sensor 14 is operated, DC power is supplied from a power circuit 27 to a transmission circuit 25 and the inside starting processing of the transmission circuit 25 is executed. When the inside starting processing is terminated, the control circuit 26 sets a transmission channel with opposite radio device designated by the dial key of an operation part 12. When it takes time in the setting processing and a press switch 13 is depressed for a prescribed distance and is turned on later, the transmission circuit 25 becomes a transmission mode and becomes a transmission start state. Thus, the conventional interruption of the state of speech does not occur even if a user starts speaking from a moment when the press switch 13 is depressed by the prescribed distance.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio apparatus of a press-talk system in which a transmission mode and a reception mode are alternately switched to communicate with a radio apparatus of the other party.

[0002]

2. Description of the Related Art Conventionally, in a press-talk type radio device, since the communication line is one circuit, pressing a press switch attached to a radio device main body puts the radio device in a transmission mode, and conversely, the other party's side. When receiving from a user, the user releases the press switch to put the wireless device in a receiving mode, and can speak only in one direction of transmission or reception.

[0003]

By the way, in the above-mentioned conventional press-talk type radio apparatus, when the user sets his / her radio apparatus to the transmission mode and talks to the other party's radio apparatus, he or she speaks with the press switch pressed down. Has become.

However, in order to prevent battery consumption, the transmission circuit starts a startup process after the press switch is pressed,
After the start-up processing is completed, transmission is enabled. Especially in a digital modulation type radio device, the power consumption of a DSP (Digital Signal Processor) is large.
After the press switch is pressed, the DSP is started, and after the operation clock is stabilized and the training is performed, the transmission is started. For this reason, a slight time lag occurs before the transmission is started.

[0005] Therefore, if the sender immediately starts talking by pressing the press switch, the beginning of the speech is interrupted without being transmitted at the beginning of the talk. For example, I had said, "Hello" is, without being transmitted is "crowded" of the speech head,
This is a phenomenon in which only "Hello" is transmitted.

The present invention has been made to solve such a conventional problem, and shortens the time from the pressing of a press switch for setting a transmission mode to the start of transmission, thereby reducing the beginning of a call that occurs during transmission. It is an object of the present invention to provide a wireless device capable of achieving cancellation or reduction.

[0007]

SUMMARY OF THE INVENTION In a wireless device according to the present invention, a press switch which is depressed a fixed distance to be turned on, a touch sensor attached to an operation surface of the press switch, and an operation of the touch sensor are detected. A control circuit for performing an internal start-up process including power supply to the transmission circuit and a transmission channel setting process for setting up a communication line with a transmission destination, detecting an ON state of a press switch and setting a transmission start state.

According to the present invention, it is possible to obtain a radio apparatus capable of shortening the time from the pressing of the press switch for setting the transmission mode to the start of transmission and eliminating or reducing the disconnection of the head of the head occurring during transmission.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention comprises a press switch which is depressed a fixed distance to be turned on, a touch sensor attached to an operation surface of the press switch, and an operation of the touch sensor. A control circuit that performs internal start-up processing including detection and power supply to a transmission circuit, performs transmission channel setting processing for setting a communication line with a transmission destination, detects an ON state of a press switch, and sets a transmission start state. It is provided.

According to the present invention, the start-up process and the transmission channel setting process by the control circuit are completed between the time when the touch sensor is operated and the time when the press switch is pressed down and turned on, so that the press switch is pressed down by a certain distance. This has the effect that even if the user starts speaking from the moment when the speech is made, the head disconnection does not occur.

According to a second aspect of the present invention, there is provided a press switch which is depressed a fixed distance to be turned on, a touch sensor attached to an operation surface of the press switch, and a transmission circuit for detecting an operation of the touch sensor and transmitting a signal to a transmission circuit. A control circuit that performs an internal startup process including power supply, detects an ON state of a press switch, performs a transmission channel setting process for setting a communication line with a transmission destination, and sets a transmission start state after the transmission channel setting process. It is provided.

According to the present invention, the internal start-up process is completed between the time when the touch sensor is operated and the time when the press switch is pressed down for a certain distance and turned on, and the transmission channel is set from the time when the press switch is turned on. Therefore, it is possible to greatly reduce the time at which the beginning of the speech is interrupted, and to greatly reduce the disconnection of the head of the speech. Further, since the transmission channel is set after the press switch is turned on, there is an effect that unnecessary power consumption for setting the transmission channel when the touch sensor malfunctions can be saved.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIGS.

(Embodiment 1) FIGS. 1 and 2 are an external perspective view and a block configuration diagram of a wireless device according to an embodiment of the present invention.

The appearance of the wireless device 1 according to the present embodiment includes a display unit 11 having an LCD (Liquid Crystal Display) on the front surface 2a of a box-shaped housing 2 and an operation unit 12 including dial buttons and various function buttons. And a press switch 13 for selecting a transmission mode and a touch sensor 14 on the side surface 2b of the housing 2, and the antenna 3 is installed on the ceiling surface 2c so as to extend and contract. The press switch 13 is a switch that is turned on when depressed by a predetermined distance d, and is normally urged outward as shown in the figure.

Note that a speaker and a microphone (not shown) are built in the front surface 2a of the housing 2. The touch sensor 14 is attached to the operation surface 13 a of the press switch 13, and is configured to operate only by touching the user to press the press switch 13.

The electrical configuration of the wireless device 1 according to the present embodiment is the same as that of the transmitting / receiving duplexer 2 connected to the antenna 3.
1. A receiving circuit 22 which is connected to the transmitting / receiving splitter 21 and operates in a receiving mode, a receiver 23 which amplifies an audio signal demodulated by the receiving circuit 22 and outputs it from a speaker, and amplifies and outputs an audio signal picked up by a microphone. And a transmitting circuit 25 that operates in the transmission mode and modulates the audio signal output from the transmitter 24 and outputs the modulated signal to the transmission / reception splitter 21. In the digital wireless device 1, a DSP is arranged in the receiving circuit 22 and the transmitting circuit 25.

The wireless device 1 includes a control circuit 26 for controlling the operation of the reception circuit 22 and the transmission circuit 25, and a power supply circuit 27 having a battery configuration for supplying DC power to each unit.
The display section 11, the operation section 12, the press switch 13, and the touch sensor 14 are connected to the control circuit 26.

Next, the operation of the wireless device 1 according to the present embodiment in the transmission mode will be described with reference to the flowchart shown in FIG. 3 and the timing chart shown in FIG.

First, when the user starts operating the press switch 13 of the wireless device 1 at time t1, the touch sensor 14 is operated because the touch sensor 14 is attached to the operation surface 13a of the press switch 13. (Step S1).

When the control circuit 26 detects that the touch sensor 14 has been operated, it supplies DC power from the power supply circuit 27 to the transmission circuit 25 to perform an internal activation process of the transmission circuit 25 (step S2). In particular, the DSP performs program reading, operation clock stabilization, training, and the like.

Suppose that time T1 is spent for the internal start-up process, and time t
When the internal activation process is completed in step 2, the control circuit 26 sets a transmission channel with the other wireless device designated by the dial button of the operation unit 12 (step S3).

When the time T2 is spent for this setting process, and the press switch 13 is depressed by a predetermined distance d and turned on at time t3 (step S4), the transmission circuit 25
Is in the transmission mode and is in the transmission start state (step S
5).

In this way, during the time T3 from the time t1 when the touch sensor 14 operates to the time t3 when the press switch 13 is depressed and turned on, the internal startup processing and the transmission channel setting processing by the control circuit 26 are completed. Preparation for transmission is completed. For this reason, the press switch 1
Even if the user starts speaking from the moment when 3 is depressed by a certain distance d, there is no occurrence of the conventional head disconnection.

If the press switch 13 is not turned on even after a lapse of a predetermined time Ts from the activation of the touch sensor 14 (step S6), the control circuit 26 determines that the touch sensor 14 has malfunctioned, The startup process ends (step S7), and the process returns to the standby state of step S1.

Next, the timing chart shown in FIG. 5 shows a case where the time T3 from the time point t1 when the touch sensor 14 is activated to the time point t3 when the press switch 13 is turned on is short because the speed at which the press switch 13 is pressed down is fast. Is shown.

In this case, at the point in time t3 when the press switch 13 is depressed and turned on, the transmission channel setting process is still being performed with the other wireless device under the control of the control circuit 26. Has not been completed.

Therefore, if the user starts speaking at this time point t3, there is a possibility that the beginning of the speech will be cut off. In this case, the transmission preparation is completed at the immediately subsequent time point t4 (| t4-t3 | <T2). The time at which the beginning of the speech is interrupted can be greatly reduced as compared with the related art, and the beginning of the speech rarely occurs.

(Embodiment 2) Next, referring to a flowchart shown in FIG. 6 and a timing chart shown in FIG. 7, another operation of the wireless device 1 in the transmission mode will be described.
A description will be given as a second embodiment.

First, when the user starts operating the press switch 13 of the wireless device 1 at time t1, the touch sensor 14 is operated because the touch sensor 14 is attached to the operation surface 13a of the press switch 13. (Step S11).

When the control circuit 26 detects that the touch sensor 14 has been operated, it supplies DC power from the power supply circuit 27 to the transmission circuit 25 and performs an internal activation process of the transmission circuit 25 (step S12). In particular, the DSP performs program reading, operation clock stabilization, training, and the like.

The time T1 is spent for the internal start-up processing, and the time t
When the internal startup processing is completed in step 2, the control circuit 26 enters a standby state. When the press switch 13 is pressed down and turned on at the subsequent time point t3 (step S13), the control circuit 26 sets a transmission channel with the other wireless device specified by the dial button of the operation unit 12 (step S14). . A time T2 is spent for this setting process, and a time t
In step 4, the transmission circuit 25 enters the transmission mode and enters a transmission start state (step S15).

If the press switch 13 is not turned on even after the lapse of a predetermined time Ts from the activation of the touch sensor 14 (Step S16), the control circuit 26
4 is determined to have malfunctioned, the internal startup process ends (step S17), and the process returns to the standby state of step S11.

As described above, the control circuit 26 controls the touch sensor 1
The internal start-up process is completed during a time T3 from the time t1 when the press switch 4 operates to the time t3 when the press switch 13 is pressed down and turned on, and the time t when the press switch 13 is turned on
Since the transmission channel setting process is performed from 3, it takes time T2 until the transmission preparation is completed after the press switch 13 is depressed. Therefore, when the user starts talking from the time t3, the talk head may be cut off. In this case, since the internal start-up process is completed and the process is performed only for the set time T2 of the transmission channel, the transmission preparation is completed immediately thereafter at time t4. Can be greatly reduced. In addition, when the touch sensor 14 malfunctions, wasteful power consumption for setting the transmission channel can be omitted.

[0035]

As described above, according to the present invention, the internal start-up process and the transmission channel setting process by the control circuit are completed from the time when the touch sensor is activated to the time when the press switch is pressed down for a certain distance and turned on. So
An advantageous effect is obtained in that even if the user starts speaking from the moment when the press switch is pressed down, the head of speech does not break.

If the time from when the touch sensor is actuated to when the press switch is turned on is short because the speed at which the press switch is depressed is fast, transmission preparation is completed when the press switch is pressed down. There is a possibility that the beginning of the conversation will be interrupted.However, since the transmission preparation is completed immediately, the time during which the beginning of the conversation is interrupted can be greatly reduced compared to the past, and the beginning of the conversation may actually occur. An advantageous effect that there is hardly any is obtained.

Further, according to the present invention, the internal activation process by the control circuit is completed from the time when the touch sensor is activated to the time when the press switch is pressed down for a certain distance and turned on, and the transmission channel is started from the time when the press switch is turned on. Is set, the time during which the beginning of the speech is interrupted can be greatly reduced, and the advantageous effect that the beginning of the talk can be greatly reduced can be obtained. further,
Since the transmission channel is set after the press switch is turned on, there is an advantageous effect that unnecessary power consumption for setting the transmission channel can be saved when the touch sensor malfunctions.
