Description

[Detailed Description of the Invention] Industrial Application Field The present invention automatically controls the switch according to the emergency warning signal transmitted from the broadcasting station even if the receiver is switched off, so that the receiver can be alerted to earthquakes, tsunamis, etc. This invention relates to an emergency warning broadcasting receiver with a clock whose purpose is to quickly transmit disaster warnings.

BACKGROUND OF THE INVENTION Emergency warning broadcasting for transmitting urgent disaster information such as earthquakes and tsunamis has begun, and an example of the operation of this conventional emergency warning broadcasting receiver with a clock will be described.

Generally, an emergency warning broadcast receiver is composed of a tuner section for receiving emergency warning broadcasts, an alarm signal coincidence detection circuit, a display for receiving emergency warning broadcasts, and a sound generator. When the start signal is detected by the alarm signal coincidence detection circuit, the display and the sound generator for receiving the emergency alert broadcast are activated by the output of the alarm signal coincidence detection circuit. At this time, the sound generator is configured to output sound at a constant volume regardless of the position of the volume control. Furthermore, by operating the operation confirmation switch for confirming the operation of the receiver, the same operating state as when the start signal was received can be set.

When the display device and the sound generator, which have been activated in this manner, detect the end signal of the emergency warning broadcast by the warning signal coincidence detection circuit, they become inoperable due to the output of this detection circuit and return to the standby condition. It also includes an OFF switch for disabling the display and the sound generator without receiving an end signal, and even by operating the OFF switch, the display and the sound generator are placed in a standby state. You can also do it.

Next, to explain the operation of the clock section, this clock section automatically outputs a control output when the time set in advance by the user of the receiver arrives, and puts the sound generator into operation so that the user knows when the set time has arrived. Like the function that notifies you, the sound generator can be automatically activated or deactivated by setting the time. This clock unit causes the sound generating unit to become inactive,
By operating an OFF switch to turn off the control output of the timer, the sound generator can be put into a non-operating state and placed in a standby state for emergency warning broadcasting.

Problems to be Solved by the Invention: Emergency warning receivers are designed to quickly notify alert recipients of alarms, and are capable of automatically turning on the receiver even if it is turned off by means of a special signal sent from a broadcasting station. This function is added to a general receiver, and it is more expensive than a general receiver.Furthermore, the provision of various operation parts on the surface of the receiver makes it difficult for the receiver to operate the receiver. This has the problem that it becomes very difficult to handle.

In view of the above-mentioned problems, the present invention provides a switch to turn off the emergency warning broadcast when the receiver is in the state of receiving an emergency warning broadcast, and a switch to turn it off when the receiver is in the operating state under the control of the clock section. By sharing a switch to turn off the alarm, the cost can be reduced by reducing the number of parts, and the receiver is easy to operate, providing an emergency warning broadcasting receiver with a clock.

Means for Solving the Problems In order to solve the above-mentioned problems, the emergency warning broadcasting receiver with a clock according to the present invention includes an antenna and a tuner section.

Alarm signal coincidence detection circuit, emergency alert broadcast reception indicator.

Sound generator 2 consists of a clock section, an operation confirmation switch, a switching diode, and an OFF switch, and an OFF signal input terminal for turning off the output of the alarm signal coincidence detection circuit and an OFF signal input for turning off the control output of the clock section. terminals and O through switching diodes, respectively.
It is equipped with a configuration that connects to an FF switch.

Function The present invention has the above-described configuration, and has a switch that turns off the receiver when it is in a state of receiving an emergency warning broadcast, and a switch that turns off the receiver when it is in an operating state under the control of a clock section. Two switches can be shared by one switch.

6.\One Embodiment An emergency warning broadcasting receiver with a clock according to one embodiment of the present invention will be described below with reference to the drawings. The figure shows a block diagram of an emergency warning broadcasting receiver with a clock according to an embodiment of the present invention.

The emergency warning broadcast receiver with a clock configured as described above will be explained using the drawings.

In the figure, the Ushizu tuner section 2, the alarm signal coincidence detection circuit 3, and the clock section 8 are always in operation, and the radio waves sent from the broadcasting station are received by the tuner section 2 via the antenna 1, and the audio signal is extracted. . The audio signal is sent to the alarm signal coincidence detection circuit 3.
is input to the sound generator 5.

When the broadcasting station is performing normal broadcasting, the sound generator 5 is turned on by the operation switch constituted by the clock section 8, and if it is in operation, it outputs audio (No. M is for volume control via the low frequency circuit 6). The sound signal is output from the speaker 7 at a volume controlled to the volume of , and when the sound generator 6 is switched off, no sound signal is output.

Next, the emergency warning broadcast is received, and the alarm signal extracted as an audio signal by the tune section 2 enters the alarm signal coincidence detection circuit 3 and detects a start signal, and the emergency warning broadcast is received by the output of the alarm signal coincidence detection circuit 3. The display 4 and the sound generator 6 are put into operation. The sound generator 5 in the operating state outputs an audio signal from the speaker 7 at a constant volume regardless of the position of the volume control.

Furthermore, the audio output at a constant volume can be obtained by using the operation confirmation switch 9, which is used to confirm the operation of the receiver by setting the same operation state as when the start signal was received.

In addition to the above-mentioned start signal, when an emergency warning broadcast is detected by the end signal circuit 3 which returns the receiver to the state before receiving the start signal, the output of this detection circuit sends an emergency warning broadcast reception indicator 4 and an acoustic signal. Return the generator 5 to the state it was in before receiving the start signal. Here, when the receiver wants to deactivate the sound generator before receiving the end signal, or when the recipient wants to deactivate the sound generator that has been activated with the operation confirmation switch 9, the alarm signal coincidence detection is performed. By operating the OFF switch 12 connected via the switching diode 10 from the OFF signal input terminal for turning off the output of the circuit 3, the output of the alarm signal coincidence detection circuit 3 is controlled, and the sound generating section 5 is brought out of the operating state. 0 that can be changed to a non-operating state.Next, the control operation of the sound generator 5 by the clock section 8 will be explained. The clock part 8 has a function to automatically control the operation of the sound generator 5 at a set time, or to automatically set an alarm at a set time, in addition to having an operation switch that keeps the sound generator 6 in continuous operation. It has the ability to make sounds. The sound generator 6, activated by the control signal from the clock section 8, outputs an audio signal from the speaker 7 at a volume controlled by the volume controller 9...the troll volume. Here, when the receiver puts the sound generator 5 into the operating state with an operation switch that continuously turns the sound generator 6 into the operating state, or when the set time comes and automatically puts the sound generator 5 into the operating state, Even when it is desired to turn off the control output from the clock section 8 and put the sound generating section 5 into a non-operating state while outputting an audio signal or alarm sound, there is a method for turning off the control output of the clock section 8. OFF switch 12 connected from the OFF signal input terminal via a switching diode 11
