Description

Technical Field

[0001] The present invention relates to a notification device, and in particular to a non-extension type remote call notification device. Background Art

[0002] The notification devices currently in use adopt the technology of telephone extensions, and such technology has many deficiencies. For example, if the microphone of one of the extensions is not hung up, the notification host will not be able to dial the fire department because the line is busy; or when the fire department calls back, due to the line of the notification host being busy, the fire department will hear a busy tone when dialing the notification host, resulting in the inability to complete the notification process. This will cause the notification device to keep dialing and the fire department's phone to keep ringing, which is a quite serious problem; in addition, if there is a call in progress, this situation will also cause the inability to hang up the local line.

[0003] In addition, the more extensions there are, the more amplification devices need to be added additionally during expansion, resulting in an increase in its installation cost. Moreover, since the extensions are connected to external telephone lines, there is an easy risk of being damaged externally, such as lightning strikes and high-voltage currents. Summary of the Invention

[0004] In view of the above problems, the purpose of the present invention is to provide a non-extension type remote call notification device that is connected to a fire telephone. The non-extension type remote call notification device includes: a notification host, a plurality of remote activation devices, and a variable source line terminal impedance unit.

[0005] The notification host includes: a notification host processing module; a telephone module, connected to the notification host processing module, including a telephone detection interface and a call module. The telephone detection interface detects the local line current and incoming call ringtone, and the call module conducts a call; a modulation and demodulation module, connected to the notification host processing module and the telephone module, dials and detects the signal tone and sends the signal tone; a voice module, connected to the notification host processing module and the telephone module, sends the stored voice; a notification host sound source module, connected to the notification host processing module, generates a notification sound source; and a notification host network module, connected to the notification host processing module.

[0006] Each remote activation device includes: an activation device processing module; a microphone unit, connected to the activation device processing module, including a microphone and a hook detection module. The microphone is used to communicate with the fire telephone, and the hook detection module detects whether the microphone is hung up; an activation device sound source module, connected to the activation device processing module, and connected to the notification host sound source module and the activation device sound source module of another remote activation device, converts the notification sound source and transmits it to the activation device sound source module of another remote activation device; a speaker module, connected to the activation device sound source module and plays the notification sound source; and a remote activation device network module, connected to the activation device processing module, and connected to the notification host network module to communicate and exchange information with the notification host network module.

[0007] A variable audio source line terminal impedance unit is connected to the audio source module of one of the remote activation devices to adjust the call volume of the microphone.

[0008] The non-extension type remote call notification device of the present invention can know whether the connected remote activation device has a communication disconnection or the microphone is not hung up (not positioned) through the local area network, or restart the remote activation device through the local area network. In addition, abnormal events such as communication disconnection, microphone not hung up (not positioned), or even failure of the aforementioned remote activation device, or restart are recorded on the notification host for query to understand the details, and it is more convenient for maintenance if a failure occurs. Furthermore, the present invention can effectively solve the serious defect in the prior art that if one extension microphone is not hung up, other extensions cannot make notifications. The remote activation device can achieve all the functions of the extension device in the prior art, such as key notification, incoming call ringing, and communication with the fire department. Also, the present invention can save more costs, for example, the remote activation device does not require NCC PSTN certification fees. In addition, since the audio source is not connected to the telephone line, the risk of external line lightning strike or high voltage can be reduced.

[0037] The following specific embodiments are given to illustrate the content of the present invention in detail, and the accompanying drawings are used as auxiliary explanations. The symbols mentioned in the specification refer to the symbol explanations.

[0038] Please refer to Figures 1 to 4 As shown, it is the schematic diagrams (1) to (4) of the non-extension type remote call notification device of the present invention. The non-extension type remote call notification device of the present invention is connected to the fire fighting telephone 80 and can be used for emergency notifications, such as fire alarms and disaster relief notifications. The non-extension type remote call notification device of the present invention includes a notification host 10, a plurality of remote start devices 20, and a variable sound source cable terminal impedance unit 50.

[0039] The notification host 10 mainly consists of a notification host processing module 11, a telephone module 12, a modulation and demodulation module 13, a voice module 14, a notification host sound source module 15, and a notification host network module 17. However, the composition of the notification host 10 is not limited thereto.

[0040] The notification host processing module 11 is preferably a processor for controlling the entire notification process and various switches.

[0041] The telephone module 12 is connected to the notification host processing module 11 and can be composed of a telephone detection interface 121 and a call module 122. Among them, the telephone detection interface 121 detects the current of the local line (i.e., the telephone line) and the incoming call ringtone, and the call module 122 is used to make and answer calls for communication.

[0042] The modulation and demodulation (modem) module 13 is connected to the notification host processing module 11 and the telephone module 12 to make a call and detect and send a signal tone.

[0043] The voice module 14 is connected to the notification host processing module 11 and the telephone module 12 to send the stored voice, where the stored voice is stored in the voice module 14.

[0044] The notification host sound source module 15 is connected to the notification host processing module 11 to generate a notification sound source. Here, the notification host sound source module 15 preferably can include a pair of sound source output lines and a pair of sound source input lines. The sound source output lines are used to output the sound source to the remote activation device 20, and the sound source input lines are used to receive the sound source from the remote activation device 20.

[0045] The notification host network module 17 is connected to the notification host processing module 11 and is used to communicate and exchange information with the remote activation device 20.

[0046] Here, the notification host 10 can further be provided with an input / output interface (not shown in the figure), which can be, for example, a plurality of operation buttons, LED lights, a display screen, etc. for operation, display, and input and output of shift reports.

[0047] The remote activation device 20 mainly can be composed of an activation device processing module 21, a microphone unit 22, an activation device sound source module 25, a speaker module 26, and a remote activation device network module 27, but the composition of the remote activation device 20 is not limited to this.

[0048] The activation device processing module 21 is preferably a processor for controlling the entire notification process and various switches.

[0049] The microphone unit 22 is connected to the activation device processing module 21 and can be composed of a microphone 221 and a hook detection module 222. Among them, the microphone 221 is used to communicate with the fire telephone 80, and the hook detection module 222 detects whether the microphone 221 is hung up.

[0050] The sound source module 25 of the starting device is connected to the processing module 21 of the starting device, and is also connected to the sound source module 15 of the notification host and the sound source module 25 of another remote starting device 20, converting the notification sound source and transmitting it to the sound source module 25 of another remote starting device 20. Here, the sound source module 25 of the starting device preferably may include a first pair of sound source output lines and a second pair of sound source output lines. Among them, the first pair of sound source output lines is used to convert the sound source from the notification host 10 and output it to the sound source input line of the next remote starting device 20; the second pair of sound source output lines is used to be connected in parallel with the second pair of sound source output lines of other remote starting devices 20 and is connected to the sound source input line of the notification host 10.

[0051] Here, since the sound source lines are divided into input and output, the sound source output of the notification host 10 to multiple remote starting devices 20 is one-to-many, so it is in series; but multiple remote starting devices 20 to the notification host 10 is many-to-one, so it is in parallel. However, the foregoing description is only for illustration and does not limit the present invention thereby.

[0052] The speaker module 26 is connected to the sound source module 25 of the starting device to play the notification sound source, or may play other sound sources to achieve the effect of sound amplification or broadcasting.

[0053] The network module 27 of the remote starting device is connected to the processing module 21 of the starting device and is connected to the network module 17 of the notification host to communicate and exchange information with the network module 17 of the notification host. Here, the network module 17 of the notification host detects the connection status of the network module 27 of each remote starting device 20; in addition, when the microphone 221 of a certain remote starting device 20 is in a call or not hung up, its network module 27 of the remote starting device can transmit this status to the network module 17 of the notification host, so that the notification host 10 can know that the microphone 221 of a certain remote starting device 20 is in a call or not hung up (it can be displayed on an external or built-in display screen or displayed by a warning light).

[0054] The variable sound source line terminal impedance unit 50 is connected to the sound source module 25 of one of the multiple remote starting devices 20 to adjust the call volume of the microphone 221. Here, the variable sound source line terminal impedance unit 50 can be connected to the first pair of sound source output lines of one of the multiple remote starting devices 20, and the sound source terminal impedance will change its requirement for increasing the call volume due to the number of remote starting devices 20.

[0055] In addition, the fire telephone 80 of the fire department can answer and dial to the notification host 10 and communicate with the remote starting device 20.

[0056] In one embodiment, the notification host 10 may further be equipped with a digital voltage regulator 18, which is connected to the notification host processing module 11 to control the amplification factor during a conference call. When multiple remote activation devices 20 are connected to the external line and a conference call is in progress, the amplification factor is controlled via the digital voltage regulator 18 to achieve the effect of adjusting the volume, and the call quality can be further improved.

[0057] In one embodiment, the digital voltage regulator 18 may further have multiple sets of impedance value parameters, which can automatically switch the corresponding impedance value parameters according to the number of remote activation devices 20 communicating with the fire telephone 80, so as to achieve the purpose of controlling the call volume and effectively improve the call quality. Here, the number of sets of impedance value parameters set by the digital voltage regulator 18 is greater than or equal to the number of remote activation devices 20 connected to the notification host 10. In other words, if the notification host 10 is connected to three remote activation devices 20, the number of sets of impedance value parameters set by the digital voltage regulator 18 is preferably three sets, but it can also be four sets or more. If the number of sets of impedance value parameters is greater than the number of remote activation devices 20, it will be convenient to increase the number of remote activation devices 20 in the future.

[0058] In one embodiment, the activation device sound source module 25 is wired in a one-in-one-out arrangement according to the internal coding. The digital voltage regulator 18 adjusts the impedance according to the call sequence of the remote activation device 20 to control the call volume. In other words, according to which coded remote activation device 20 answers the call first, the digital voltage regulator 18 automatically switches the corresponding impedance to control an appropriate call volume for communicating with the fire telephone 80. That is to say, the sound source wiring of the remote activation device 20 is wired in a one-in-one-out arrangement in sequence according to the internal coding. Usually, the later the remote activation device 20, the smaller the sound. Especially for the last remote activation device 20, in this embodiment, according to which coded remote activation device answers the call first, the digital voltage regulator 18 automatically switches the corresponding impedance to control an appropriate call volume for communicating with the fire department.

[0059] Furthermore, when communicating with the fire telephone 80 of the fire department, it can be a multi-to-one call. The notification host 10 is provided with a digital voltage regulator 18. The sound source wiring of the remote activation device 20 is wired in a one-in-one-out arrangement in sequence according to the internal coding. According to the number of remote activation devices 20 communicating with the fire telephone 80 of the fire department at the same time, and according to the preset parameter value to control the impedance, the corresponding impedance is adjusted and switched to control an appropriate call volume for communicating with the fire telephone 80 of the fire department.

[0060] In one embodiment, the activation device sound source modules 25 of the respective remote activation devices 20 are connected to the notification host sound source module 15 of the notification host 10 in parallel.

[0061] As shown Figure 4 In one embodiment, the variable audio source line terminal impedance unit 50 may further be provided with a detection module 51 to detect the number of remote activation devices 20, and the variable audio source line terminal impedance unit 50 may automatically adjust the impedance according to the detection result.

[0062] As shown Figure 4 In one embodiment, the variable audio source line terminal impedance unit 50 may further be provided with a switching module 52 to switch between multiple sets of impedances, that is, the switching module 52 can be switched to different impedances.

[0063] In one embodiment, the activation device audio source module 25 of the activation device may perform mutual conversion of voltage and current on the audio source and output it to the activation device audio source module 25 of another remote activation device 20.

[0064] In one embodiment, the notification host audio source module 15 may transmit the stored voice to the activation device audio source module 25 of the remote activation device 20, and the activation device audio source module 25 drives the speaker module 26 to play the stored voice.

[0065] In one embodiment, the notification host audio source module 15 of the notification host 10 may transmit multiple types of frequency tones of the modulation / demodulation (modem) module 13 to the activation device audio source module 25 of the remote activation device 20, and the activation device audio source module 25 drives the speaker module 26 to play the frequency tones. Here, the frequency tones may be, for example, signal tones, analog ringing tones when a fire department calls, etc.

[0066] In one embodiment, the notification host network module 17 of the notification host 10 may detect the connection status of the remote activation device network module 27 of each remote activation device 20. When the remote activation device network module 27 of the remote activation device 20 is not connected to the notification host network module 17 of the notification host 10, the remote activation device 20 will issue a warning. Here, for example, the remote activation device 20 may be provided with a display screen (not shown in the figure) or a warning light (not shown in the figure), and the notification host network module 17 of the notification host 10 can detect the local area network to know whether the remote activation device network module 27 of each remote activation device 20 is connected. If there is a disconnection, a warning can be issued through the display screen or warning light of the remote activation device 20 to achieve the function of self-detection. In addition, the remote activation device 20 can also directly issue a warning through the display screen or warning light according to the connection status of the remote activation device network module 27.

[0067] In one embodiment, when the hook detection module 222 of the remote activation device 20 detects that the microphone 221 is not hung up, a signal that the microphone 221 is not hung up can be generated and transmitted to the notification host network module 17 of the notification host 10 through the remote activation device network module 27, so that the notification host 10 knows that the microphone 221 of the remote activation device 20 is not hung up.

[0068] In one embodiment, when the notification host 10 learns that the microphone 221 of the remote startup device 20 is not hung up, the notification host 10 can generate a shutdown signal and send it to the remote startup device 20 with the microphone 221 not hung up. The remote startup device 20 deactivates the microphone 221 according to the shutdown signal.

[0069] In one embodiment, after the microphone 221 is deactivated (for example, the remote startup device 20 deactivates the microphone 221 according to the shutdown signal), if the hook detection module 222 detects that the microphone 221 is hung up (i.e., the user hangs up and positions the microphone 221), the remote startup device 20 can re-enable the microphone 221.

[0070] In one embodiment, the notification host 10 can send a restart signal to the remote startup device 20, and the remote startup device 20 can restart according to the restart signal. Here, the notification host 10 can send a restart signal to any one of the remote startup devices 20. Therefore, any one of the remote startup devices 20 can be restarted via the notification host 10, or all of the remote startup devices 20 can be restarted simultaneously.

[0071] Thus, if a non-voice call notification is to be made, or if the manual or linked notification trigger of the notification host 10 or the remote startup device 20 is activated, the notification host 10 makes a notification. The notification process is as follows:

[0072] Step 1.1: Dial the phone to the fire department's fire phone 80: The notification host 10 switches the trunk line, detects the dial tone through the modulation and demodulation module 13, and then dials the number.

[0073] Step 1.2: At this time, the fire phone 80 rings. The notification host 10 detects through the modulation and demodulation module 13 that the fire phone 80 of the fire department rings and the ringing stops, and then determines that the fire department has answered the call.

[0074] Step 1.3: The notification host plays the signal tone provided by the modulation and demodulation module 13 and the stored voice of the modulation and demodulation module 13 to the fire phone 80 of the fire department, and at the same time, through the sound source output line to the sound source input line of the remote startup device 20, and broadcasts through the speaker module 26.

[0075] Step 1.4: The notification host 10 pauses for 5 seconds, detects the busy tone of the fire department's phone through the modulation and demodulation module 13, and determines whether the fire department has hung up the phone according to the presence or absence of the busy tone. If there is no busy tone, go to Step 1.3.

[0076] Step 1.5: Hang up the phone and wait for the fire department to call. Wait for 20 seconds. If there is no call, go to Step 1.1.

[0077] Step 1.6: Ring the remote start device 20, and notify the host 10 through the ring tone detection of the phone detection interface 121, send the ring tone through the modem module 13 to simulate the ring tone, through the sound source output line to the sound source input line of the remote start device 20, and broadcast it through the speaker module 26 to remind the user at the location to answer the phone. If the ringing does not stop, hang up the phone after 2 minutes, complete the notification, and go to step 1.8.

[0078] Step 1.7: When the ringing stops, it is considered that the fire department has hung up the phone, and the notification is completed.

[0079] Step 1.8: Press the reset button on the notification host 10 or the remote start device 20 to complete the notification.

[0080] If a call notification is to be made, the notification host 10 or the remote start device 20 is manually or linked to trigger the notification, and the notification host 10 makes the notification. The notification process is as follows:

[0081] Step 2.1: Dial the fire telephone 80 of the fire department: notify the host 10 to switch the office line, detect the dial tone through the modem module 13, and then dial.

[0082] Step 2.2: At this time, the fire telephone 80 rings, and the notification host 10 detects through the modem module 13 that the fire telephone 80 of the fire department is ringing and the ringing stops, and then determines that the fire department has answered the call.

[0083] Step 2.3: The notification host plays the signal tone provided by the modem module 13 and the stored voice of the modem module 13 to the fire telephone 80 of the fire department, and at the same time broadcasts through the sound source output line to the sound source input line of the remote activation device 20 through the speaker module 26. If the microphone 221 of the remote activation device 20 is picked up, the call is carried out in step 2.8.

[0084] Step 2.4: The notification host 10 stays for 5 seconds, and the modem module 13 detects the busy tone of the fire department's phone. The fire department hangs up the phone based on whether there is a busy tone. If the microphone 221 of the remote start device 20 is picked up, go to step 2.8 to make a call. If there is no busy tone, go to step 2.3.

[0085] Step 2.5: Hang up the phone and wait for the fire department to call. Wait for 20 seconds. If there is no call, go to step 2.1.

[0086] Step 2.6: Ring the remote start device 20 to inform the host 10 that through the ring detection of the telephone detection interface 121, the ringtone is sent out as an analog ringtone through the modulation and demodulation module 13, through the sound source output line to the sound source input line of the remote start device 20, and broadcast by the speaker module 26 to remind the user at the location to answer the phone. If the microphone 221 of the remote start device 20 is picked up, inform the host 10 to answer the call, go to Step 2.8 for the call. If the ringing does not stop, hang up the call after 2 minutes, complete the notification, and go to Step 2.9.

[0087] Step 2.7: If the ringing stops, it is considered that the fire department has hung up the phone, then complete the notification, and go to Step 2.9.

[0088] Step 2.8: The remote start device 20 communicates with the fire department. If the modulation and demodulation module 13 detects a busy tone from the fire department or all the microphones 221 of the remote start devices 20 in normal calls have been hung up, then hang up the local line and complete the notification.

[0089] Step 2.9: Press the reset key on the notification host 10 or the remote start device 20 to complete the notification.

[0090] If there is a call notification for the remote start device 20 with the microphone 221 not hung up before the notification, then deactivate this microphone 221 at this time. The notification process is as follows:

[0091] Step 3.1: Dial the phone to the fire department's fire telephone 80: The notification host 10 switches the local line, detects the dial tone through the modulation and demodulation module 13, and then dials the number.

[0092] Step 3.2: At this time, the fire telephone 80 rings. The notification host 10 detects through the modulation and demodulation module 13 that the fire telephone 80 of the fire department rings and the ringing stops, then judges that the fire department has answered the call.

[0093] Step 3.3: The notification host plays the signal tone provided by the modulation and demodulation module 13 and the stored voice of the modulation and demodulation module 13 to the fire telephone 80 of the fire department. At the same time, through the sound source output line to the sound source input line of the remote start device 20, and broadcast through the speaker module 26. If the microphone 221 of the remote start device 20 is picked up, go to Step 3.8 for the call.

[0094] Step 3.4: The notification host 10 pauses for 5 seconds, detects the busy tone of the fire department's phone through the modulation and demodulation module 13, and judges whether the fire department has hung up the phone according to the presence or absence of the busy tone. If the microphone 221 of the remote start device 20 is picked up, go to Step 3.8 for the call. If there is no busy tone, go to Step 3.3.

[0095] Step 3.5: Hang up the phone and wait for a call from the fire department. Wait for 20 seconds. If there is no call, go to Step 3.1.

[0096] Step 3.6: Ring the remote activation device 20. Notify the host 10 to detect the ringtone through the ringtone detection of the phone detection interface 121, send out an analog ringtone through the modulation and demodulation module 13, through the sound source output line to the sound source input line of the remote activation device 20, and broadcast it by the speaker module 26 to remind the user at the said location to answer the phone. If the microphone 221 of the remote activation device 20 is picked up, notify the host 10 to answer the phone, go to Step 3.8 for a call. If the ringing does not stop, hang up the phone after 2 minutes, complete the notification, and go to Step 3.9.

[0097] Step 3.7: When the ringing stops, it is considered that the fire department has hung up the phone, then complete the notification, and go to Step 3.9.

[0098] Step 3.8: The remote activation device 20 communicates with the fire department. If the modulation and demodulation module 13 detects a busy tone from the fire department or all the microphones 221 of the remote activation devices 20 in normal calls have been hung up (excluding the previously deactivated microphones 221, but if the deactivated microphones 221 in the notification are hung up again, they can be re-enabled), then hang up the local line, and the notification is completed.

[0099] Step 3.9: Press the reset key on the notification host 10 or the remote activation device 20 to complete the notification.

[0100] In summary, for the non-extension type remote call notification device of the present invention, it can know whether the connected remote activation device 20 is disconnected from communication, the microphone is not hung up (not located), or restart the remote activation device 20 through the local area network. In addition, abnormal events such as communication disconnection, microphone not hung up (not located), or even failure of the aforementioned remote activation device 20 or restart are all recorded on the notification host 10 for querying to understand the details, and it is more convenient for maintenance if a failure occurs. Furthermore, the present invention can effectively solve the serious defect in the prior art that if one extension microphone is not hung up, other extensions cannot be notified. The remote activation device 20 can achieve all the functions of the extension device in the prior art, such as key notification, incoming call ringing, communicating with the fire department, etc. Also, the present invention can save more costs, for example, the remote activation device 20 does not require NCC PSTN certification fees. In addition, since the sound source is not connected to the telephone line, the risk of external line lightning strike or high voltage can be reduced.

[0101] Of course, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
