When there is a response, it sends security information, etc. consisting of the own terminal number, the block to which the alarm belongs, the specified data of the related block, the data of the specified block, and a data end signal to the alarm receiving center, and When there is no response from the receiving center, the sending of the security information, etc. to the alarm receiving center is abandoned and the security information, etc. and line status information indicating that there is no response are stored in a storage means. The security terminal device according to the present invention is provided with a call control means for controlling the information stored in the storage means to be sent to the alarm reception center when there is an incoming call from the alarm reception center. A security terminal device with characteristics can be obtained.

Examples of this invention Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram showing the configuration of an implementation fa11 of the security terminal device according to the present invention. In FIG. 2, a telephone number storage unit 101 stores the telephone number of the alarm reception/1δ center and sequentially transmits the numbers in accordance with the dialing timing of the network control unit 104. In addition to detecting good news, it also detects signals that manage the main body itself, such as starting and canceling reservation, and sends information corresponding to each to the information storage section 106.

The scheduled transmission control section 103 has an internal clock.

For example, a scheduled transmission request signal k is sent to the information storage section JO6 every two hours. The network control unit 104 is the information transmission control unit 10
In response to the activation request signal from 7, the alarm reception center is dialed via telephone line a.

The telephone port i1J a is connected to the information transmitting/receiving section 105, and when the transmission operation is completed, the telephone line a is restored. If the network control unit 104 detects two incoming calls, it outputs an incoming call detection signal m to the incoming call control unit 108.

The information transmitting/receiving unit 105 converts the security data f from the information storage unit IO6 into a multi-frequency signal (MF multiplied signal).

The information sending control unit sends the security information C to the alarm receiving center via the telephone line a, and converts the control signal 1 sent from the alarm receiving center into a digital signal, for example, a voice band signal of 1800 Hz, etc. 107 Outputs center signal e. When the information storage unit 106 detects an alarm or the like with the sensor 102 or receives the scheduled oscillation request signal k from the scheduled transmission control unit 103, the information storage unit 106 outputs the information transmission request signal j to the information transmission control unit 107, and then controls the information transmission. The security data f is outputted to the information transmitting/receiving section 105 in accordance with the timing clock g sent from the section 107, and a transmission end signal l is outputted to the information transmitting control section 107 when the transmission is completed. The information storage unit 106 still stores the security information until it receives the normal end signal, and also remembers that there was no response from the reporting center to the transmission abandonment signal n.

The information sending control section 107 outputs the timing cross g to the information storage section 106 in response to the control signal from the information transmitting/receiving section 105, that is, the center signal e, and the transmission to the alarm receiving center is completed T (that is, the control signal e in FIG. 1). After receiving the normal end WH from the information reception center, a normal end 1 flag is output to the information storage section 106. The information transmission control unit 107 is still L.
It has a function that automatically dials a predetermined number of times when there is no response from the f-loss receiving center (including when the line is busy), and if the information receiving center does not respond even after the predetermined number of automatic dials are completed. is the transmission abandonment signal n.

It is output to the information storage section 106 and the incoming call control section 108.

The incoming call control unit 108 has an internal timer and sends a transmission abandonment signal n.
After receiving the incoming call detection signal m within a certain period of time, for example, 5 minutes.
The status transmission request signal t is output to the information transmission control unit 107 only when the status transmission request signal t is received.

The operation of the present invention will be explained below with reference to FIG.

First, it is assumed that only the own terminal number and data end code are stored in the information storage unit 106 as an initial state. In this state, when an alarm etc. occurs, the sensor etc. 102 detects the alarm and sends the specified data of the block to which the alarm belongs and related blocks (transmission block data in Fig. 1), and the data of the specified block ( Intoxication information in Figure 1).

is sent to the information storage section 106. The information storage unit 106 stores this information, that is, security information, etc., and then outputs an information transmission request signal j to the information transmission control 107. Upon receiving the information transmission request signal j, the information transmission control section 107 transmits an activation request signal S to the network control section 104. Network control unit 104
The telephone number storage unit 101 is activated by this activation request signal.
The telephone number of the alarm reception center stored in the telephone number is dialed via the telephone line a in accordance with the dial timing.

At this time, if there is no response from the alarm reception center even after dialing a predetermined number of times due to reasons such as two-line busy, the information transmission control section 107 sends a transmission abandonment signal n to the information storage section 10.
6 and output to the incoming call control unit 108. Information storage unit 10
6 stores line state information indicating that there is no response from the alarm reception center due to the transmission abandonment signal n, and 2 call control unit 108 activates the call control unit 108 according to the transmission abandonment signal n.

In this state, the occurrence of the previous report will not be transmitted to the alarm reception center.

Thereafter, the scheduled transmission control section 10:3 learns from the clock that a predetermined time has elapsed, and sends a scheduled transmission request signal k to the information storage section 106. When the information storage unit 106 receives the scheduled transmission request signal 1, it outputs the information transmission request signal j to the information transmission control unit 107.
When receiving the information transmission request signal j, it sends an activation request signal j to the network control section 104. In response to this activation request signal, the network control section 104 dials the telephone number of the alarm reception center stored in the telephone number storage section 101 via the telephone line a in accordance with the dialing timing.

However, even in this case, there may be cases where there is no response from the alarm reception center even after dialing a predetermined number of times due to reasons such as a busy line as described above. In this case, the information sending control unit 107 transmits the transmission abandonment signal n to the information storage unit 106 and the call receiving control unit 1.
Output to 08. The information storage unit 106 stores the line status information in the same way as described above in response to the transmission abandonment signal n, while the second call control unit 108 starts a timer in response to the transmission abandonment signal n.

At the alarm reception center, the above-mentioned scheduled transmission signal, which should be sent at predetermined intervals, is not being sent.

Make a call to the security terminal device. The network control unit 104 of the security terminal device detects an incoming call via telephone line a, and
The incoming call detection signal m is output to the incoming call control section 108. When the incoming call control unit 108 receives the incoming call detection signal m within 5 minutes after the timer starts, it outputs the status transmission request signal t to the information sending control unit 107. The information transmission control unit 107 that has received the status transmission request signal t starts transmitting the timing clock g to the information storage unit 106. The information storage unit 106 that has received the timing clock g sends the stored security information, etc. and circuit status information to the information transmitting and receiving unit 105 as I'l (itti data f.Information yld transmitting and receiving unit 1
05 converts this security data f into a multi-frequency signal and sends it to the alarm reception center via telephone line a. When the alarm receiving center receives the data end code (see Figure 1) sent at the end of the received signal, it sends a normal end signal (in a voice band such as 1800 Hz) to the security terminal device via telephone line a. (see Figure 1). The information transmitting/receiving section 105 of the security terminal device converts the normal completion signal d, which is an analog signal, into a digital signal and outputs it to the information sending control section 1 (17) as a center signal e. 110till ) and outputs a transmission end signal i to the information transmission control section 107.The information control section 107, which has received the transmission end signal i, turns off the activation signal.Network control section 104
Knowing that the transmission operation is completed by turning off this activation signal, the telephone line A is restored.

In addition, although the above embodiment describes an example equipped with the scheduled transmission control section 103, this scheduled transmission control section 103
2 is not an essential component of the present invention, and configurations other than this are also possible.

Of course, it is included in the present invention.

Effects of the Invention As explained above, the present invention can be applied even when there is no response from the alarm reception center and the transmission of security information is abandoned.

This is because the security information etc. can be transmitted when there is an incoming call from the alarm reception center.

Confirmation from the alarm reception center is now possible, which is effective in centrally monitoring a large number of terminal devices.
