Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic reporting terminal device for automatically reporting to a monitoring center or the like. Various automatic systems such as an emergency call system for home care support for the elderly, a mechanical security system, a home security system for reporting illegal intrusions and gas leaks in houses, a facility monitoring system for monitoring various facilities with sensors, etc. Notification systems are known. Such an automatic notification system automatically notifies a monitoring center or the like from an automatic notification terminal device via a telephone line when an abnormality occurs. Therefore, when the exchange is in a congested state, or when all the lines to be notified such as the monitoring center are busy, automatic notification cannot be performed. In such a case, it is required to improve reliability by making it possible to report to other monitoring centers.

[0002]

2. Description of the Related Art FIG. 7 is an explanatory view of an automatic notification system. Reference numeral 51 is a monitoring center, 52 is an exchange, 53 is an automatic notification terminal device, 54 is a telephone line, 55 is various sensors, 56 is an emergency button, and 57 is an emergency button. Automatic caller including dial function, 5
Reference numeral 8 is a control processing unit.

The control processing unit 58 controls the automatic calling unit 57 by pressing the emergency button 56, detecting the occurrence of a fire by the sensor 55, detecting the occurrence of gas leak, detecting the illegal intrusion, detecting the occurrence of an abnormality in the surveillance machine, and the telephone line 54. The dial number of the monitoring center 51 is sent to. The exchange 52 receives and identifies this dial number to call the monitoring center 51, and the monitoring center 5
Data such as the cause of the abnormality is sent from the control processing unit 58 by the automatic response 1 or the manual response 1.

In this case, if the telephone line 54 to which the automatic notification terminal device 53 is connected is a dial pulse (DP) line, the exchange 52 automatically connects the DP receiver by detecting the calling of the automatic notification terminal device 53. The dial pulse from the automatic calling section 57 of the notification terminal device 53 is received and identified. If the telephone line 54 is a push button (PB) line, the exchange 52 connects the PB receiver upon detection of the calling of the automatic notification terminal device 53, and pushes from the automatic calling unit 57 of the automatic notification terminal device 53. The button signal will be received and identified.

That is, the automatic calling unit 57 of the monitoring center 51 of the report destination corresponds to the dial type whether the telephone line 54 is a dial pulse (DP) line or a push button (PB) line. The dial number sending function is set. Normally, this is done by switching the setting switch when the automatic notification terminal device 53 is installed.

[0006]

[Problems to be Solved by the Invention] Automatic notification terminal device 53
Since the first installation is performed by an expert or a technician and the test report is sent to the monitoring center 51, the setting error of the dial type does not occur. But,
The installation location may be changed or the dial type of the telephone line 54 may be changed. In that case, for example, when the dial pulse (DP) line is changed to the push button (PB) line, the dial type of the telephone line 54 will not match unless the setting of the dial type of the automatic calling section 57 is switched. Therefore, automatic notification to the monitoring center 51 cannot be performed.

Further, it has been proposed to automatically determine the dial type of a telephone line in a general telephone and set the dial type of a built-in automatic dial sending section. In such a telephone, whether or not the dial type setting is correct can be easily identified by the calling operation.
Also, when the other party is busy, it can be easily identified by the busy tone, so that the call is called again after a while. However, it is necessary for the automatic notification terminal device to automatically and quickly notify the notification destination such as the monitoring center, and when the first notification destination such as the monitoring center is busy, the automatic notification terminal device notifies the second notification destination. Need to report. It is an object of the present invention to quickly determine a dial type and enable re-call processing or prompt notification to other callees by detecting when the callee is busy.

[0008]

The automatic notification terminal device of the present invention will be described with reference to FIG. 1. A call answering unit 1 that forms a loop with a telephone line 10 to form an off-hook state, Automatic dial unit 2 for sending dial pulse (DP) or push button (PB) signals to the telephone line 10.
A polarity reversal detection unit 3 for detecting a polarity reversal signal due to a report destination response from the exchange 7, a signal detection unit 4 for detecting AC signals of various signal tones from the exchange 7, and a signal type from the exchange. And a control processing unit 5 for controlling each unit
And a storage unit 6 for storing the dial type of the report destination, the control processing unit 5 sends the dial number of the report destination by a dial pulse or a push button signal, and dials the telephone line 10 depending on whether or not the dial tone stops. The type of call is automatically called to the callee, the presence or absence of a response from the callee is monitored, and the busy tone is detected when the callee is busy. It has a control structure for automatically calling.

Further, the control processing section 5 controls the calling response section 1 to form a loop in the telephone line 10 to bring it into an off-hook state, and based on the detection of the dial tone from the exchange by the signal detection section 4, the automatic dial section 2 Control and send the first digit of the dial number of the callee by selecting either dial pulse or push button signal for the dial type, and when the dial tone stops, send the remaining digits. , The dial type at that time is stored in the storage unit 6, and when the dial tone does not stop, the other one of the dial types is selected and the first digit of the dial number of the callee is sent, and when the dial tone stops, the rest remains. All digits are sent and the dial type at that time is stored in the storage unit 6. When the dial tone does not stop again, all digits are sent according to the previous dial type stored in the storage unit 6, and the dial of the call destination is sent. After sending all digits of the number The presence / absence of a response of the information destination is determined by the presence / absence of polarity inversion detection from the exchange by the polarity inversion detection unit 3, and the presence / absence of busy signal detection by the signal detection unit 4 is determined by the signal detection unit 4 whether or not the destination is busy. , Call response unit 1 when busy signal is detected
Is set to a re-calling state, and the dial number of the report destination or another report destination is sent from the automatic dial unit 2 in all digits according to the previous dial type.

[0010]

The control processing unit 5 controls the call response unit 1 to be in an off-hook state due to the occurrence of an automatic notification event such as a detection signal from a sensor or the pressing of an emergency button. Dial to. At that time, since the dial type of the telephone line 10 is unknown, for example, a dial pulse is transmitted. If the dial tone is stopped by this, it means that the dial pulse is received by the DP receiver of the exchange 7, so that it can be determined that the line is a dial pulse line. If the dial tone does not stop, the push button signal is switched to be sent. If the dial tone stops due to this, it means that the push button signal has been received by the PB receiver of the exchange 7, so it can be determined that the line is a push button line. In either case, if the dial tone does not stop, the dial number of the callee is sent according to the previous dial type stored in the storage unit 6. When a busy tone is detected when the callee is busy, a re-call process is performed. In this case, the calling process is performed by switching to the same report destination or another report destination.

Further, the control processing unit 5 controls the calling response unit 1 in the off-hook state when an automatic notification event occurs. As a result, the exchange 7 sends a dial tone. The dial tone is detected by the signal detection unit 4, the detected signal is applied to the control processing unit 5, and then the control processing unit 5 controls the automatic dial unit 2 to send the dial number of the callee. In that case, the dial type is selected and the first digit of the dial number is transmitted. When the control processing unit 5 determines that the dial tone cannot be detected by the signal detection unit 4 as a result, the dial type at that time is determined to be correct, the dial type is stored in the storage unit 6, and the automatic dial unit 2 To send the remaining dialed digits. If the dial tone continues to be transmitted from the exchange 7, the dial type is switched and the first digit of the dial number of the report destination is transmitted again. If the dial tone is stopped thereby, it is determined that the dial type at that time is correct, the dial type is stored in the storage unit 6, and the remaining dial digits of all digits are sent from the automatic dial unit 2. If the dial tone does not stop even if the first digit of the dial number is transmitted by any of the dial types, all digits of the dial number of the callee according to the previous dial type stored in the storage unit 6 are transmitted.

After sending all digits of the dial number of the callee, whether or not the polarity reversal detection unit 3 detects a polarity reversal signal from the exchange 7, and whether or not the signal detection unit 4 detects a busy tone from the exchange 7. Is monitored by the control processing unit 5, and when the polarity reversal signal is detected, it means that the report destination has responded, and therefore data is transmitted. Also, when there is no polarity reversal signal detected and a busy tone is detected, all the lines to be reported are busy,
Perform re-call processing. In this case, all digits of the dial number of the previous report destination or another report destination are transmitted according to the previous dial type without determining the dial type of the telephone line 10.

Also, the speech network unit 14 is a two-line-
It has a hybrid circuit function that performs 4-wire conversion. Further, the modem unit 15 detects, for example, a 400 Hz dial tone from the exchange and an intermittent busy tone of 0.5 second on and 0.5 second off by digital processing, and outputs the detection signal S2 to the input / output control unit 17. And corresponds to the signal detection unit 4 in FIG. The modem section 15 is switched between a mode for receiving data by a mode switching signal SWS from the input / output control section 17 and a detection mode for an AC signal such as 400 Hz, which is modulated after the callee responds. The mode is switched to the data reception mode for receiving the received data.

Further, the dialer section 16 has a dial pulse D
P and the push button signal PB are switched by the switching signal SWD from the input / output control unit 17, and the dial pulse D according to the dial number from the microprocessor 18.
In the case of P, the loop of the loop forming unit 12 is turned on and off,
In the case of the push button signal PB, an oscillator for generating a push button signal of a combination of two frequencies corresponding to the dial number is provided, and the push button signal is sent out via the speech network unit 14. Corresponds to part 2. Further, the microprocessor 18 is shown in FIG.
The memory 19 corresponds to the control processing unit 5 of FIG.
It stores the rank of the callee, the dial number and dial type of the callee, and the like. The memory 19
Can also be an external memory.

FIG. 3 is an operation flow chart of the embodiment of the present invention. As described above, the microprocessor 18 is not shown in the drawing due to the occurrence of a notification event due to the detection signal of the sensor or the pressing of the emergency button (a1). A message such as an abnormality is output from a speaker (not shown) by using a voice synthesizing means or the like (a2). Then, the call reception is monitored to see if the telephone line 11 is in use and the external telephone is disconnected (a3). That is, the telephone line 11 is not in use.

Then, the microprocessor 18 applies an off-hook signal OFK to the loop forming section 12 via the input / output control section 17 to bring it into a hook-off state (a4), and forms a loop on the telephone line 11. In the exchange, loop detection is performed in the subscriber circuit or the like, the dial tone trunk is connected, and the dial tone is sent to the telephone line 11. Therefore, the microprocessor 18 of the automatic notification terminal device performs the dial tone detection processing 1
Is started (a5). Since the dial tone is a continuous signal of 400 Hz, for example, it is detected by the modem unit 15 and the detection signal S2 is transferred to the microprocessor 18 via the input / output control unit 17.

The microprocessor 18 detects the detection signal S2.
If it is determined that a dial tone has been detected because the call has continued for a predetermined time, it is next determined whether or not it is the first report destination (a6). In the case of the first report destination, only the first digit of the dial number is dialed ( a7) If not the first report destination, dial all digits of the dial number (a12). Then, the process proceeds to step (a11).

If the first digit is dialed, then
The dial tone detection process 2 for determining the dial type is started (a8). Then, it is determined whether or not the dial tone for one second is not detected (a9), and the dial tone detection signal S2 by the modem unit 15 is detected.
When the dial tone is not detected (continuous OFF), the exchange stops sending dial tone by receiving the dial because the first one digit dial is the correct dial type. 16 is controlled to dial the second and subsequent digits (a10). Then, the timer is started for 32 seconds (a11).

When a dial tone is detected in step (a9), that is, when the dial transmission of the first digit is an incorrect dial type, the exchange does not receive the dial, so the dial tone is transmitted. Will continue,
In that case, it is determined whether or not both PB / DP have failed (a13), and when both are not failed, the PB / DP is switched to the DP and the DP / B is failed to the PB (a15). ), And the first digit of the dial number of the report destination is dialed again (a7). If both PB / DP fail, the dial type is set as the first type and the memory 19
(A14), and all digits are dialed according to the dial type (a12). In such repeated processing, a flag is provided in the microprocessor 18 to indicate whether it is the first time or the second time, so that it is possible to easily discriminate one failure or both failures of the PB / DP.

After the 32-second timer is started in step (a11), the polarity reversal detection process is started (a1
6) The presence / absence of polarity reversal is determined (a17). That is, the detection unit 13 detects whether or not the polarity of the telephone line 11 is reversed, and the polarity inversion detection indicates that the callee has responded.
In that case, data transmission / voice synthesis message output is performed (a19). Further, a busy sound detection process is performed (a20), and when the busy sound and the polarity inversion signal are not detected, it is determined whether or not the 32-second timer has timed out (a18). When the process of a19) is completed, the current dial type is stored in the memory 19 in the case of the first report destination (a21), the presence or absence of the next report destination is determined (a22), and if there is no next report destination, the process ends. If there is a next report destination, the line is released by switching to the next report destination and controlling the loop forming unit 12 (a23), and the process proceeds to step (a3).

FIG. 5 shows a dial tone detection process 1 according to the embodiment of the present invention.
4 is a flowchart of FIG. 3 and shows the processing in step (a5) of FIG. That is, after the hook-off (a4),
Start the 3-second timer (b1). Then, the modem section 15 is set to the signal detection mode to perform the signal detection processing at 400 Hz (b2). Then, it is determined whether or not a signal is detected (b3), and if it is not a signal, the process proceeds to step (b7). If a signal is detected, it is determined whether or not the dial tone on-timer has been started (b4), and the start is performed. If not already started, the dial tone on-timer is started (b5), and when the dial tone on-timer has been started, and after the start, it is judged whether or not it is on for 1 second continuously (b6). It is determined that the sound is detected (b9), and the process proceeds to step (a6). If the signal is not detected in step (b3) and the signal is not turned on for 1 second continuously in step (b6), it is determined whether or not the timer for 3 seconds has timed up. The process moves to (b2). If the time is up, it is determined that no dial tone has been detected, and the process moves to step (a6).

FIG. 6 shows a dial tone detection process 2 according to the embodiment of the present invention.
4 is a flowchart of FIG. 3 and shows the processing in step (a8) of FIG. That is, the first 1 of the dial number of the report destination
Dial the digit (a7) and start the 2-second timer (c1). Then, by detecting the dial of the first digit, it is detected whether or not the exchange has stopped transmitting the dial tone.
The 400 Hz signal detection process is started (c2).

ON detection when a 400 Hz signal is detected,
When the detection cannot be made, the OFF detection is performed, and it is determined whether the ON timer has been started or not by the OFF detection (c3).
When the N timer has been started, the ON timer is stepped and cleared (c4). After this process or when the ON timer is not started, it is determined whether the OFF timer is started (c5). If not started, the OFF timer is started (c6), and the OFF timer is started or started. It is determined whether the current OFF time is 1 second or longer (c7), and if it is not 1 second or longer, 2
It is determined whether or not the second timer time is up (c8), and if it is not time up, the process proceeds to step (c2). If time is up, the stop of the dial tone is detected, but the stop does not continue for a predetermined time In this case, it is judged that the dial type is neither correct nor correct (c9), and the process proceeds to step (a13).

At step (c7), the current OFF
If the time is 1 second or longer, it is determined that the dial type is correct (c15), and the 2-second timer and the OFF timer are cleared (c16). Then, the process proceeds to step (a10).

If the ON detection is made in step (c2), it is judged whether or not the OFF timer has been started (c1
0) If the timer has been started, the OFF timer is stopped and cleared (c11). After this processing or when the OFF timer has not been started, it is determined whether the ON timer has been started (c12). If it has not been started, the ON timer is started (c13). After this processing or if the ON timer has been started, the current ON time is 1
It is determined whether the time is longer than 2 seconds (c14), and if it is not longer than 1 second, the process proceeds to step (c8). If the time is longer than 1 second, it is determined that the dial type does not match (c17) and the 2 second timer is set. Clear (c18). Then, the step (a1
Go to 3).

As described above, the occurrence of the report event causes the microprocessor 18 to determine the dial type.
The first digit of the dial number of the callee is controlled by the dial type stored in the memory 19 and sent out. In this case, the dial type switching signal SWD is applied from the microprocessor 18 to the dialer section 16 via the input / output control section 17 to control switching between dial pulse and push button signal. And the dial pulse D
If it is P, the loop forming unit 12 is controlled to send dial pulses by turning the loop on and off to the telephone line 11, and if it is a push button signal PB, it is sent to the telephone line 11 via the speech network unit 14. To be done.

If the dial type in this case is correct, the exchange stops the dial tone, so the microprocessor 18 determines whether or not the dial tone is detected by the modem unit 15, and continues for a predetermined time or longer, for example, 1 second or longer. If not detected, it is determined that the dial tone has stopped, and in this case, it is determined that the dial type of the first 1-digit dial transmission is correct, and the dialer unit 16 is immediately controlled to transmit all the remaining digits. .
Therefore, the maximum of the dial tone detection test is 3 seconds, but as mentioned above, when it is determined that the dial tone has stopped after 1 second, dial the remaining digits immediately. Therefore, prompt notification is possible. In this case, memory 1
Since the dial type stored in 9 is correct,
The stored contents of the memory 19 are left unchanged.

If the dial tone is continuously detected, it means that the dial type is not correct. Therefore, the dial number is switched to another dial type and the first digit of the dial number of the receiver is sent again. If the dial tone stops, it can be determined that the dial type in this case is correct, so the memory 19 is updated to the dial type in this case. In addition, this memory 1
It is also possible to control the update of the dial type of 9 so as to be performed when the callee responds, that is, when the polarity inversion signal is detected.

If the dial tone does not stop even after switching the dial type, it is estimated that the line condition is deteriorated or that the DP receiver or PB receiver of the exchange is temporarily out of order, and the memory is All digits of the dial number of the report destination are transmitted according to the previous dial type stored in 19.

As described above, since the dial type is determined by sending the one digit of the dial number, it is possible to make the determination in a shorter time compared with the case where the dial type is determined after sending all digits. After sending all digits, the presence or absence of a response from the callee is determined by the presence or absence of a polarity reversal signal, and at the same time whether or not the callee is busy is determined by the presence or absence of busy signal detection, and the polarity reversal signal is detected. When the callee responds, the data is sent, and when the polarity reversal signal cannot be detected and the busy tone is detected, the callee is busy and the dial type is determined. Recall processing or call processing to another destination is performed without performing. That is, when there are a plurality of report destinations, it is possible to automatically notify the second report destination while the first report destination is talking.

[0033]

As described above, according to the present invention, the dial type is determined by the dialing of the first digit of the dial number of the callee when the report event occurs due to the sensor detection signal or the pressing of the emergency button. Even if the line is changed after the automatic notification terminal device is installed, it is possible to make a quick and automatic judgment compared to the case where the dial type is judged by sending all digits of the dialed number. It is possible to dial the addressee based on the result. Further, even when the dial tone does not stop by the first dialing of the leading one digit, the leading one digit can be dialed again by continuously switching the dialing type and the dial type can be judged without releasing the line. Furthermore, after sending all digits of the dial, the polarity reversal signal detection and busy tone detection are performed, and when the callee is busy, all digits of the dial number are sent to the re-call processing or other callees. As a result, there is an advantage that an emergency automatic call can be surely made.
