JPH05175878A - Press-to-talk speaking controller - Google Patents

Abstract

PURPOSE:To provide the press-to-talk controller which simplifies structure and improves operability. CONSTITUTION:When a press-to-talk switch 1 is turned on, this is detected by an ON detection part 11. When the ON of the switch 1 is detected, a transmission permission part 12 permits transmission. At the same time, an ON time count part 13 starts counting time t1. When an OFF detection part 14 detects the OFF of the switch 1, a comparison part 15 judges whether the time t1 is longer than prescribed time (t) or not. In the case of t1>=t, a transmission inhibit instruction part 16 is operated to inhibit the transmission of speaking. On the other hand, in the case of t1<t, a transmission continuation instruction part 17 permits the continuation of speaking transmission. Thus, either temporary speaking or continuous speaking can be selected by the ON time of the press-to-talk switch 1, and operability is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a press talk call control device, and more particularly to a press talk call control device capable of selecting one of two call methods according to the operation of a press talk switch.

[0002]

2. Description of the Related Art Conventionally, a paging system has been adopted in a large construction site, a photo studio or the like so that workers, site supervisors and the like can communicate with each other. In this paging system, the worker, site supervisor, etc. individually carry a portable transceiver in a pocket.

This transceiver operates without any operation on the receiving side. However, when transmitting or transmitting, the press talk switch provided on the transceiver can be operated. You will need it. This press talk switch can be operated in two ways. One is a simple operation that turns on while the press talk switch is pressed and turns off when released, and the other is a lock operation that locks the press talk switch after it has been pressed and turned on.

When the former simple operation is performed, the user can talk only while the user presses the press talk switch with his finger. On the other hand, when the latter lock operation is performed, even if the press of the press talk switch is released, the ON state is locked, so that the call can be transmitted while it is locked.

The receiver operates regardless of whether the press talk switch is on or off, and is always effective.

[0006] The same communication means as described above is also used in a broadcasting station or the like on an operation panel of an operator of a broadcasting device for giving instructions to performers through a window made of transparent glass or a plastic plate. ..

[0007]

As described above, the conventional press talk switch is configured to allow a simple ON operation and a locked ON operation depending on the way of operation by the user. There are problems that the structure of the switch and the structure of the housing are complicated and that the manufacturing cost is high.

Further, in order to lock the press talk switch, it is necessary to perform an operation other than the operation of pressing the switch, for example, the operation of pressing and rotating the switch or the operation of sliding while pressing the switch. In order to do so, for example, an operation of pressing and turning in the reverse direction, or an operation of pressing and sliding in the opposite direction is required, and there is also a problem in terms of operability.

An object of the present invention is to eliminate the above-mentioned problems of the conventional device, and to provide a press talk communication control device having a simple structure and improved operability.

[0010]

In order to achieve the above object, according to the present invention, a count unit for measuring the ON time of the press talk switch and a time t1 measured by the count unit are predetermined. It is characterized in that it is provided with a comparing section for comparing with a predetermined time t, and means for switching the communication method depending on the magnitude relation between the times t1 and t.

[0011]

According to the present invention, if the ON time t1 of the press talk switch is shorter than the predetermined time t, continuous communication can be performed, and if the ON time t1 is longer than the predetermined time t, temporary communication can be performed. it can.

Therefore, the continuous call and the temporary call can be selected by a simple operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings. FIG. 2 is a block diagram showing a hardware configuration of an example of the press talk communication device of the present invention. In the figure, 1
Is a press talk switch, 2 is a control device (CPU), 3
Is a communication device and 4 is an antenna. Further, 5 is an exchange that sends and receives signals to and from the antenna 4. Although the illustrated example is a wireless press talk communication device, it may be wired.

Next, the operation of the control device 2 will be described with reference to FIGS. 3 and 4. FIG. 3 is a flow chart for explaining the operation of the control device 2, and FIG. 4 is a time chart for turning on and off the press talk switch 1.

In step S1, it is determined whether or not the call is continuing. If this determination is negative, the process proceeds to step S2, and it is determined whether or not the press talk switch 1 has been pressed.

When the press talk switch 1 is pressed, the process proceeds to step S3 to start a call, and a timer (not shown) starts counting the switch pressing time t1. Next, in step S4, it is determined whether or not the press of the press talk switch 1 is restored. When the depression is restored, the process proceeds to step S5 to stop counting the switch depression time t1.

In step S6, it is judged whether or not the switch pressing time t1 is longer than the set time t.
When this determination is negative, the process proceeds to step S7 and the operation of continuing the call is continued. On the other hand, when the determination in step S6 is affirmative, the process proceeds to step S10 to disconnect the call.

That is, as shown in FIG. 4 (a), when the pressing time t1 of the press talk switch 1 is longer than a preset time t, the press state of the press talk switch 1 is in the calling state. It will be canceled as soon as it returns.

Further, as shown in FIG. 4 (b), when the pressing time t1 of the press talk switch 1 is shorter than a preset time t, the pressing state of the press talk switch 1 is not effective in the talking state. It continues even if it is canceled. That is, it becomes a continuous call.

If it is determined in step S1 in FIG. 3 that the call is being continued (Yes in step S1), the process proceeds to step S8, and it is determined whether the press talk switch 1 is pressed. When the determination is negative, the call is continued. When this determination is affirmative, the process proceeds to step S9, and it is determined whether or not the depression of the switch 1 is restored. If this determination is positive, the process proceeds to step S10, the continuation of the call is ended, and the call is disconnected.

That is, in FIG. 4B, when the switch is pressed a second time, the call state is released.

As described above, according to the present embodiment, the press talk switch 1 can have a simple structure, and depending on the length of time the switch 1 is pressed, continuous call or non-continuous call can be selected. As a result, the operability is greatly improved compared to the conventional one.

In the above-described embodiment, the continuous call is made when the pressing time t1 of the press talk switch 1 is shorter than the set time t, and the temporary call (non-continuous call) is made when the press time is longer than the set time t. It may be.

Next, a second embodiment of the present invention will be described with reference to FIG. As shown in FIG. 4A, the point that the continuous call is made when the pressing time t1 of the press talk switch 1 is shorter than the set time t is the same as the first embodiment. However, in this embodiment, the press talk switch 1
The call is continued even when the pressing time t1 is longer than the set time t, and when the set time t elapses, a signal such as a control tone is transmitted.

This control tone is sent to, for example, the main unit of the paging system, and when the main unit detects the control tone, a special operation, for example, the content of the talker's utterance is set by the paging system. It performs an operation of broadcasting with a speaker in a certain premises, or an operation of enabling a telephone call with a telephone connected by wire via the main device.

This operation ends when the press talk switch 1 is pressed again and then turned off.

According to this embodiment, continuous call and special call can be selected depending on the length of time the switch 1 is pressed.

Next, the function of the present invention will be described with reference to the functional block diagram of FIG.

In the figure, 1 is a press talk switch, 11 is an ON detection part of the press talk switch 1,
Reference numerals 12 and 13 are a transmission permission section and an on-time counting section that operate when the on-detection section 11 detects the on-state. Reference numeral 14 is an OFF detection unit of the press talk switch 1, and reference numeral 15 is a comparison unit that operates when the OFF detection unit 14 detects that the switch 1 is OFF. The comparison unit 15 compares the time t1 measured by the on-time counting unit 13 with a predetermined time t.

When it is judged from this comparison that t≤t1, the transmission prohibition instruction section 16 operates to stop the transmission operation.

On the other hand, when it is determined that t> t1, the transmission continuation instructing section 17 continues the transmission operation. Next, the ON detector 18 detects that the press talk switch 1 is ON,
Then, when the off detection unit 19 detects off, the transmission prohibition instruction unit 16 operates to stop the transmission operation.

As a result, when the ON time t1 of the press talk switch 1 is shorter than the predetermined time t, the continuous call is made, and when the ON time t1 is the predetermined time t or more, the discontinuous call, that is, the temporary call is made. ..

The ON detection units 11 and 18 and the OFF detection units 14 and 19 are usually the same, but in FIG. 1, for convenience of description, different reference numerals are given and they are described separately.

[0034]

As is apparent from the above description, according to the present invention, the time t1 during which the press-talk switch is turned on can be temporarily changed by making the time t1 longer or shorter than the predetermined time t. You can choose between call and continuous call. Therefore, there is an effect that the selection operation of the temporary call and the continuous call is simple, the configuration of the press talk call control device can be simplified, and the cost can be made inexpensively.
