This case is related to the indoor intercom system, especially regarding an intercom system with unilateral forced broadcast function.

In the prior art indoor intercom system, a plurality of communication devices are usually connected to a central control host to achieve mutual communication, and the other communication devices can be directly broadcast by a single communication device. For example, a plurality of telephones can be used for dialing and broadcasting functions of multiple points through a telephone switchboard or an IP PBX network switch for command and voice concatenation.

For the architecture of data transmission through the IP network, a packet switch is usually required to relay, and the data of the single end can be forcibly broadcasted to other ends, for example, the invention patent of the Republic of China invention patent I325705.

In the foregoing system architecture, a relay device, such as a packet switch, a telephone switchboard, or an IP PBX network switch, becomes a necessity, increasing the cost of hardware and hardware construction. In the event of a new addition, deletion of the door number, and the need to re-set through the telephone switchboard or IP PBX, maintenance must be managed, and the system management troubles.

In the prior art, the indoor intercom system needs to pass through the relay device to achieve the mandatory broadcast. In view of the above problems, the present invention proposes an intercom system having a unilateral forced broadcast function, which can save the construction of the relay device and can be further applied to the built-in security system.

In order to achieve the above object, the present invention provides a regional communication system having a unilateral forced broadcast function, comprising a regional communication network for providing network connection; and a plurality of broadcast communication devices communicating with each other through the regional communication network, and Each of the broadcast communication devices can be switched to a master broadcast terminal and send broadcast data; wherein the broadcast communication device switched to the master broadcast terminal can issue a start command to at least one other broadcast communication device, so that The other broadcast communication device is forcibly switched to the controlled broadcast terminal to receive and execute the broadcast material.

The aforementioned broadcast material may be a combination of communication instructions, sound, video, text, music, pictures or the aforementioned items.

Through the start command, the broadcast communication device can be switched to the main control broadcast terminal and the controlled broadcast terminal. The broadcast control effect can be achieved without the need for the central control switch between the broadcast communication devices, and the architecture of the security system can be further applied. To protect the construction of the central control host.

As shown in FIG. 1 , an intercom system with a unilateral forced broadcast function, including a regional communication network 100 and a plurality of broadcast communication devices 200, is disclosed in the embodiment of the present invention.

As shown in "Figure 1," the regional communication network 100 is used to provide network connectivity. The regional communication network 100 is a wired or wireless network.

As shown in FIG. 1 and FIG. 2, each of the broadcast communication devices 200 includes a broadcast communication module 210 connected to the regional communication network 100 to enable the broadcast communication devices 200 to pass through the area. The communication networks 100 are connected to each other for communication and data transmission. Each of the broadcast communication devices 200 can be switched to a master broadcast terminal and send broadcast data, or be forced to switch to the controlled broadcast terminal after receiving a start command.

As shown in "3A", "3B" and "3C", three broadcast communication devices 200 will be described as an example. A plurality of broadcast communication devices 200 can be switched to the master broadcast terminal, and the start command and the broadcast data are sent to the other broadcast communication device 200, so that the other broadcast communication devices 200 are forcibly switched to the controlled broadcast terminal. Receive and execute broadcast material. Further, the user can select one of the broadcast communication devices 200 as the main control broadcast terminal. In this case, the remaining broadcast communication devices 200 can be selected as the controlled broadcast terminal, and the controlled broadcast terminal can be Single or multiple. After the selection is completed, the master broadcaster will issue a start command and transmit a start command to each of the remaining selected broadcast communication devices 200, whereby each of the broadcast communication devices 200 will be forced according to the received start command. Switching to the controlled broadcast end to receive broadcast data.

The aforementioned broadcast material may be a combination of communication instructions, sound, video, text, music, pictures or the aforementioned items. For example, the voice communication device 200 further includes a radio device 220 and a sound amplification device 230.

The radio device 220 is connected to the broadcast communication module 210. When a start button on the broadcast communication device 200 as the master broadcast terminal is pressed, the master broadcast terminal sends a start command to the other broadcast communication device 200 through the area communication network 100, so that each other broadcast communication device 200 is switched to Charged to the broadcast side. At this time, the radio device 220 of the master broadcast terminal, for example, a microphone, also starts to receive the sound, so that the broadcast data sent by the master broadcast terminal is the sound received by the radio device 220.

The sound amplification device 230 is connected to the broadcast communication module 210. After each of the other broadcast communication devices 200 is switched to the controlled broadcast terminal, the sound amplification device 230, such as a speaker, is also activated, and the sound received by the sound pickup device 220 is emitted to execute the broadcast data. In this way, the user on the master broadcast terminal can broadcast to the user of the controlled broadcast terminal.

As shown in "Fig. 4", after the broadcast communication device 200 is switched to the master broadcast terminal A, the user is operated and the broadcast function is activated (Step 110). At this time, the master broadcast terminal may first send a ring signal of less than one second to the controlled broadcast terminal B, C, so that the controlled broadcast terminal B, C issues a ringing prompt (Step 210).

The master broadcast terminal A then issues a start command (Step 120) and generates broadcast data to set the communication time and broadcast content (Step 130). At this time, based on the broadcast data, the controlled broadcast terminals B, C activate the sound amplification device 230 or other devices (such as the display device 260 and the light number indication device 270 described later) to output the broadcast data (Step 220). Finally, the master broadcast terminal A and the controlled broadcast terminal B, C enter the standby state after the set communication time elapses (Step 140, 230).

The aforementioned voice communication is only an example, and the broadcast data is not limited thereto.

Another example is to secure the device detection signal as broadcast material and forcibly transmit it to each controlled broadcast terminal.

In this example, each of the broadcast communication devices 200 includes a security device detection module 240 connected to the broadcast communication module 210, and is respectively connected to at least one security detection component 250 for receiving each security detection. The detecting signal of the component 250 is switched, and the broadcast communication device 200 is switched to be the main control broadcast terminal, and the startup command is generated and the detection signal is used as the broadcast data, and the other broadcast communication device 200 is forced to play.

The aforementioned security detecting component 250 can be a reed switch, an infrared sensor, an emergency help button, a fire detector or a gas detector.

For example, as shown in Figure 1 and Figure 2, with the fire detector as an example, when the security detection component 250 detects a fire alarm, the inspiring detection signal will be transmitted to the corresponding broadcast communication device. The broadcast communication module 210 of 200, at this time, the broadcast communication device 200 will be triggered by the detected signal and switched to the primary broadcast terminal. The broadcast communication device 200 will send a start command to the other broadcast communication device 200 through the broadcast communication module 210, so that the other broadcast communication device 200 is switched to the controlled broadcast terminal, and receives the detection signal as the broadcast data. The controlled broadcaster performs broadcast data to perform a fire alarm, for example, driving the sound amplifying device 230 to emit a warning sound.

In the foregoing architecture, each broadcast communication device 200 is switched to the main control broadcast terminal, and can play the role of preserving the central control host, and drive the warning sounds of each area. Therefore, the intercom system with the unilateral forced broadcast function of the present invention, when combined with the security detecting component 250, can be a security system without the need to additionally install a security central control host.

The aforementioned warning warning is not limited to the warning sound, and may also include the display of the warning picture. For example, each of the broadcast communication devices 200 further includes a display device 260 connected to the broadcast communication module 210 for displaying broadcast data, and the broadcast data may be a picture, an image, etc., and is not limited to being a security warning. Broadcast material attached to the voice broadcast.

Similarly, broadcast materials containing simple messages do not necessarily require the use of display devices. For example, when a fire alarm is issued, the area where the fire alarm is abnormal can be indicated by a light. Here, each of the broadcast communication devices 200 includes a light number indicating device 270 connected to the broadcast communication module 210 to display the light number according to the broadcast data. In addition, the broadcast data may be stored in the broadcast communication device 200 in advance. For example, in the case of a security application, the security detection component 250 provides only a simple detection signal to trigger the broadcast communication device 200 without further generating broadcast data. At this time, the broadcast communication device 200 can further include a storage device 280 connected to the broadcast communication module 210 for storing data. After the broadcast communication device 200 is triggered and switched to the main control broadcast terminal, the broadcast communication module 210 automatically extracts the corresponding data as the broadcast data. Alternatively, when being the controlled broadcast terminal, the voice, text, music, photos, and the like emitted by the master broadcast terminal may be directly stored in the storage device 280 of the controlled broadcast terminal after the display is performed.

The foregoing storage device 280 can be a memory card, a USB expansion device, a hard disk or a network storage device.

In addition, not all other broadcast communication devices 200 are necessarily switched to the controlled broadcast terminal. For example, the master broadcast terminal may first select a single or multiple controlled broadcast terminals, and the start command may add a corresponding identification code corresponding to the selected broadcast terminal. When the disclosed identification code is met, the broadcast communication device 200 is switched to the controlled broadcast terminal, and the speaker, the screen is directly turned on, and a broadcast prompt sound or a broadcast prompt screen appears at the same time.

The effect of the present case is that by switching between the main control broadcast terminal and the controlled broadcast terminal, the broadcast control device 200 does not need a central control switch, and the broadcast effect can be achieved, and the architecture of the security system can be further applied, and the security is saved. Control the host's construction.
