Abstract

PROBLEM TO BE SOLVED: To easily set the sound volume of a ringer for informing a call without using any special hardware. SOLUTION: When a responding switch 38 for responding to a call at the time of a normal operation is pressed for a while at the time of power supply, a CPU 31 actuates and processes a program for setting a sound volume in an ROM 32. In this program, the ringer with various volumes is repeatedly operated until the above-mentioned responding switch pressing is released, and when the responding switch pressing is released during the ringer tone, the singing level at that time is set as the volume level at the time of the normal operation.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed control device which receives calls from a plurality of calling devices via wireless communication, stores and displays the contents of the calls, and further notifies the calling by a ringing device. The present invention relates to a method for setting a volume of a ringing device when a call request is made.

2. Description of the Related Art FIG. 2 is an explanatory diagram of a paging system using a radio transmission line, in which a fixed control device 2 and movable paging devices 1, 1,... Are connected by a radio transmission line. . In this figure, the calling devices 1, 1,.
Indicates only three units, but in general this may be more.

FIG. 3 is a block diagram showing the configuration of the control device 2. The CPU 31 controls the operation of the entire control device.
A memory (ROM) 32 for storing an operation procedure (program) of U31, a memory (RAM) 33 for temporarily storing information necessary for the operation of the CPU 31, and receiving and receiving radio signals from a calling device A wireless transceiver 34 for transmitting data for responding based on the received data,
A ringing device 35 for sounding a buzzer or the like in response to a signal from the calling device, a volume level setting unit 37 and an input port 36 for the CPU to take in information therefrom, and a response signal to the calling device that made the calling request. It comprises a push button 38 for emitting and an input port 39 for taking in contact information.

[0004]

In the above-mentioned prior art, the sound volume level setting section 37 is constituted by, for example, a volume using a variable resistor or a plurality of resistors and switches. The CPU 31 sets the sound volume of a buzzer or the like based on the setting information of the sound volume level setting unit 37. However, in this conventional technique, there is a problem that circuit parts for setting the sound volume level are required, and the cost is increased.

An object of the present invention is to provide a sound volume setting method which can realize a low-cost sound volume setting mechanism which does not require circuit components for setting a sound volume when a buzzer or the like sounds, which is a problem of the prior art. It is in.

[0006]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a method for generating a ringing sound when a call is made from a calling device via a wireless transmission path. A volume setting method for setting a volume level of the ringing sound of a called device in which an operator is notified and an operator operates a response switch to respond to the calling device, wherein When the power of the apparatus is turned on while the response switch is kept pressed, the operation starts, and a plurality of predetermined volume levels are sequentially sounded for a predetermined time, and during the sounding, And setting the volume level during the sounding as the level of the subsequent sounding when the pressed state of the response switch is released.

[0007]

Embodiments of the present invention will be described below. FIG. 1 is a block diagram showing a configuration example of a control device configured to set a ringing sound volume at the time of calling using the volume setting method according to the present invention, and FIG. 4 shows an operation of the volume setting method. It is a flowchart shown. The configuration of FIG. 1 differs from the conventional configuration of FIG. 2 in that the conventional volume level setting unit 37 and its input port 36 are eliminated, and the other hardware configurations are the same. . Where R
A program for setting the volume is added to the program stored in the OM 32, and performs the processing shown in the flowchart of FIG.

The volume setting program is started when the power of the control device is turned on while the push button 38 for response is kept pressed, and the parameter j is set to 1 (step 41). Next, if j ≦ jmax (step 42),
The volume level L is set to L (j) (step 43).
The software-set volume level L is determined by the CPU 31
Is output to the ringing device 35, and the ringing device 3
5 sounds at a volume level corresponding to the volume level L (step 44). In this state, if the response switch is turned off before the predetermined time T elapses (step 4).
5, 46), the sound volume level at that time is determined as the sound level for the subsequent normal operation (step 48), and the program for sound volume setting is terminated to shift to the normal operation.

If the response switch is not turned off even after the lapse of the set time T, the routine proceeds to step 47, where the parameter j is incremented by 1, and the routine returns to step 42. At this time, j = 2, the volume level L = L (2), and the ringing device 35 sounds at a volume corresponding to L (2) for a predetermined time T or until the response switch 38 is turned off. This operation is repeated below, and the volume can be set by turning off the response switch at a desired volume level while the user listens to the sound. When the predetermined volume has jmax stages corresponding to j = 1 to jmax, and the response switch is not turned off until j> jmax, the process returns from step 42 to step 41 and returns to j again. Move to the operation from = 1.

According to the above-described volume setting method, only the program provided for the volume setting is provided, and there is no need to particularly provide a volume level setting means having a conventional hardware configuration. The control device can be configured at a low cost.

In the processing shown in FIG. 4, if the sound level corresponding to the set sound volume level L is displayed simultaneously with the sound volume level at that time, the setting operation can be more easily understood.

[0012]

According to the present invention, a hardware circuit for setting the volume is not required, the control device can be economically constructed, and the setting can be made while listening to the actual sound in advance according to the use environment. Can be easily performed, so that an appropriate setting can always be made.
