Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an indoor-related alarm device that communicates or notifies rooms.

[Background technology] Recently, houses have become more and more two-story structures, airtight, and sound insulated, and family communication has become neglected. Furthermore, especially in households where there are elderly or sick people, there was a problem that even if the elderly or sick person called for help from family members, other family members could not hear their voices. For this reason,
Conventionally, there are devices that allow family members to communicate wirelessly, but when installing the child device and the parent device, there were problems such as it being difficult to fix and requiring a large space for installation.

Therefore, as a way to improve this point, for example, the main unit as a main unit is buried in the wall of a room where family members are likely to be present, such as the living room or kitchen. A transmitter as a slave device is buried in the wall of a patient's room, etc., and this main device and each transmitter are connected to each other.
By connecting with wire wiring and pressing the push button on the transmitter, the main unit will display that there is a call, and the buzzer will sound to call the family member who is on the main unit side. There was something that improved communication and made it possible for the elderly and sick to contact each other for help.

However, with conventional indoor alarms of this type, when transmitters are placed in multiple rooms and a call is received from the transmitter, the buzzer sounds the same and it is difficult to tell which room the call is coming from. In order to confirm this, there was a problem in that it was necessary to check the display on the main unit installed in each room.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and its object is to provide an indoor room in which calls from each room in which a transmitter is installed can be identified by sound. The purpose is to provide a communication alarm.

A call button that is connected by a signal line and is operated when calling the main device side, and a notification device that notifies you of a response sound when a call is received from the main device or when the main device responds to the call. A constant voltage is individually applied between the signal line and a plurality of response call buttons provided on the transmitter and operated when individually calling each transmitter or individually responding to a call from the transmitter. a constant voltage means, and a call detection means for detecting which transmitter is calling from the current flowing between the signal lines when the call button of the transmitter is operated and any of the signal lines is short-circuited. and a notification device that notifies the caller by distinguishing from which transmitter the call is coming from based on the detection output of the call detection means, and a call signal or a call signal via the signal line when any of the answer call buttons is operated. The main appliance is equipped with a response sound sending means that sends out a response signal and sounds a ringing tone or answering sound from the notification device of the corresponding transmitter, and the call detection means detects which of the current flowing between the signal lines is detected. The system detects whether the call is coming from a transmitter, and based on the detection output of the call detection means, the notification device distinguishes which transmitter the call is coming from and notifies the call. It is designed so that it can be clearly identified.

As shown in the figure, an additional buzzer 27 can be added to another room. In other words, when a call is received from the transmitter 2, the family member is not necessarily present in the room where the main device 1 is installed. Therefore, in order to be able to notify you of a call as reliably as possible, we installed two additional buzzers in each other room.
7 can be provided.

The transmitter 2 is connected to the main unit 1 by a two-wire non-polar wiring, and a call button 6 is connected between these two wires, and a response call button 21 is connected between the two wires. Buzzer 2 to which the basic oscillator circuit 19 output is applied via transistor Q ₂ when operated
It is equipped with 2.

The operation of the example of the present invention will be described below. First, it is assumed that a certain call button 6 is pressed to call a member of a family member who is present at the main unit 1 installed in the kitchen, for example. When the transmit button 6 of the transmitter 2 is pressed, the wires connecting the main device 1 and the transmitter 2 are short-circuited. Due to this short circuit caused by the transmission button 6, the current flowing through the resistance _R1 of the transmission detection section increases. Therefore, the voltage across the resistor _R1 increases, turning on the transistor _Q4 , and turning on the transistor _Q4 turns on the transistor _Q3 . At this time, since the output inverted via the inverter I becomes a low level, the indicator lamp 3 corresponding to the transmission button 6 pressed on the display section 16 is turned on. Note that this display section 16
The indicator light 3 remains lit until the time limit T seconds of the timer circuit section 17 has elapsed as shown in FIGS. 4a and 4b, or until the response call button 21 is pressed as shown in FIGS. 4c and d. continue. In the notification sound generation section 18,
Depending on which transmitter 2 receives a call, the oscillation frequency of the basic oscillation circuit 19 is switched high or low by the switching circuit, and the output of the flicker oscillation circuit 20 is output or stopped, thereby producing a different ringing sound for each transmitter 2. emanate. In addition, the buzzer 5 is the call button 6.
It is designed to emit a notification sound only while it is pressed. FIG. 3 is a diagram showing that the ringing sound of the buzzer 5 on the main device 1 side is made different for each transmitter 2 in each room. For example, when four transmitters 2 are provided, each transmitter 2 It is designed to emit continuous high-pitched sounds, high-pitched flickering sounds, continuous low-pitched sounds, and low-pitched flickering sounds. In this way, the person on the main device 1 side can be called with a different sound depending on the call from each transmitter 2, so the person on the main device 1 side can hear the call from which room using only the ringing tone. You can know what. Then, the person in the room where the main device 1 is installed, who hears this notification sound, presses the answering call button 21.
is pressed as shown in Fig. 3 j to m. By pressing this response call button 21, the output of the basic oscillation circuit 19 is applied to the base of the transistor _Q2 , and is applied to the transmitter 2 via two wires to generate the buzzer 22 of the transmitter 2.
sounds as shown in Fig. 3 b, d, f, and h.
Therefore, the person making the call can confirm by this answer tone that the person on the main device 1 side has noticed the call. When the user presses the response call button 21 for the above-mentioned response, the buzzer 22 of the transmitter 2 sounds to call the person on the transmitter 2 side.

Furthermore, the operation of this embodiment will be briefly explained. When the call button 6 is pressed, a ring tone sounds while the call button 6 is pressed. Then, the indicator light 7 of the transmitter 2 lights up, and the indicator light 3 on the main device 1 side lights up. Then, when the person on the main device 1 side who hears the ringing tone presses the response call button 21, the buzzer 22 of the transmitter 2 sounds. Furthermore, when the response call button 21 is pressed, the timer circuit section 17 is reset.
Therefore, the indicator light 3 is turned off. Although the control circuit for the indicator light 7 on the transmitter 2 side is not shown, it is designed to turn off at the same time as the indicator light 3.

In addition, if the response call button 21 is pressed after the time-limited operation of the timer circuit section 17 has ended, the indicator light 3,
7 is off, so the buzzer 2 on the transmitter 2 side
2 only beeps.
