Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to Which the Invention Pertains] The present invention relates to a security terminal device for a security monitoring system using a telephone line, and particularly to information sending means of the security terminal device.

[Description of prior art]

Conventionally, in this type of security system, as shown in the procedure shown in Figure 1, for example, a security terminal automatically dials an alarm reception center, and when a response is received from the center, the terminal's sensor detects the call. Security information such as alarm signals is converted into multi-frequency signals and sent to the alarm reception center. If there is no response from the alarm receiving center even after performing automatic dialing a predetermined number of times, transmission is abandoned. Furthermore, this security terminal device performs automatic dialing at regular intervals and sends out a scheduled outgoing signal in order to notify the alarm reception center whether or not the terminal is operating in a confidential manner. The system automatically dials a predetermined number of times, but if there is no response, the transmission is abandoned.

At the alarm reception center, if the scheduled transmission signal does not arrive, it treats the device as abnormal and takes the same actions as when an alarm occurs, but the reason why the scheduled transmission signal does not arrive is due to a malfunction of the terminal. In many cases, the cause is the traffic on the line, and it is necessary to distinguish between the two in order to take appropriate measures. However, conventional terminals have the disadvantage that in order to confirm that the reason for not receiving the scheduled outgoing signal is due to one of the above, a person must actually go to the location where the terminal device is installed and inspect it.

[Purpose of the invention]

The present invention has been developed in view of the above-mentioned technical problem, and can actually be used even when a call made by automatic dialing from a security terminal device to a W alarm reception center does not arrive due to abandonment or the like and is determined to be abnormal. In addition to making it possible to determine whether there is a failure in the terminal device without having to go to the location where the terminal device is installed and inspect it, the alarm #fl necessary for the alarm reception center
1 Security terminal device that can reliably send out N-reports.
The purpose is to serve.

[Key points of the invention]

According to the present invention, when an automatic dialing call from a security terminal device to an alarm receiving center does not arrive due to abandonment or the like and it is determined that the terminal is abnormal, the alarm receiving center calls the security terminal device, If a call is received from an alarm receiving center within a certain period of time after the call is abandoned, the security information of the terminal device can be sent to the alarm receiving center, so that it can be determined whether the terminal device is malfunctioning or not. This is what I did. The feature of the present invention is that security information from sensors, etc. is divided into blocks, and WltJ
If this occurs, the alarm reception center will be automatically dialed.
It transmits its own terminal number, zone 1, 1 to which the above-mentioned alarm belongs, designated data of the related block, data of the designated block, and data end signal, and also transmits a scheduled transmission signal at regular intervals. In a security terminal device configured to automatically dial up to a predetermined number of times, there is provided a means for detecting a response signal from an alarm receiving center, a means for remembering that there is no response from the alarm receiving center, and an incoming call. and a timer that measures the time from the time when the alarm receiving center does not respond and abandons data transmission, and when an incoming call is detected within the time set by the timer, the alarm receiving center automatically The configuration is such that the terminal status signal is sent out at the time when GoogleTru is started.

[Explanation based on examples]

Hereinafter, the present invention will be explained based on the drawings.

FIG. 2 is a block diagram of an apparatus according to an embodiment of the present invention.

In the figure, the sensor 102 is not a component according to the present invention, but is described for purposes of explanation. This sensor 102

The scheduled transmission control unit 103 includes an internal clock circuit, and sends a scheduled transmission request signal k to the information storage unit 106 every two hours, for example.

The information storage section 10G is connected to the information transmission/reception section 105 and the information transmission control section 107, and sends the security data f to the information transmission/reception section 105.
7, the timing lock g1 normal end signal h, transmission end signal i, information transmission request signal j, and transmission abandonment signal n are sent and received. When the information storage section 106 detects an alarm etc., it outputs an information transmission request signal j to the information transmission control section 107, and then sends it from the information transmission control section 107 in accordance with the timing lock g. security data `` is output to the information transmitting/receiving section 105, and when the transmission is completed, a transmission end signal i is output to the information transmitting control section 107.

The information transmitting/receiving unit 105 is connected to the network control unit 104, and transmits security data f from the information storage unit 106 to a multi-frequency signal (
The security information C is created by converting it into an MF multiplied signal, and is transmitted from the network control unit 104 to the alarm reception center via the telephone line a, and at the same time, the control signal sent from the alarm reception center, such as 180011z, etc. The voice band signal is converted into a digital signal and outputted to the information transmission control section 107 as a center signal e.

A telephone number storage section 101 is connected to the network control section 104 .

This telephone number storage section 101 stores the telephone number of the alarm care center, and sequentially sends telephone number data to the network control section 104 in accordance with the dialing timing of the network control section 104. Network control unit 104 k;l information transmission control unit 10
In response to the activation request signal from 7, the alarm receiving center sends out a google signal via telephone line a and calls telephone line a.
is connected to the information transmitting/receiving section 105, and when the transmission operation is completed, the telephone line a is restored.

Further, an incoming call control unit 10B is connected to this network control unit 104, and when the network control unit 104 detects an incoming call, it outputs an incoming call detection signal m to the incoming call control unit 108.

When the information transmission control section 107 receives the information transmission request signal j from the 1n information storage section 106, it activates the network control section 103 and transmits the security information C to the alarm reception center via the telephone line a. Further, by receiving a control signal from the alarm reception center, that is, a center signal e, from the information transmitting section 105, a timing clock g for transmission is outputted to the information storage section 106. Furthermore, after the transmission to the alarm reception center is completed, a consolidation end signal is output to the information storage section 106. Furthermore, this information transmission control unit 107 has a function of automatically dialing a predetermined number of times when there is no response from the alarm receiving center (including when the line is busy), and even if the predetermined number of automatic dials are completed, If there is no response from the alarm receiving center, a transmission abandonment signal n is output to the information storage section 106 and the call control section 108.

The incoming call control unit 108 sends the status transmission request signal -M, 1 to the information sending control unit 107 only when the incoming call detection signal m is received within a certain period of time, for example, within 5 minutes after receiving the transmission abandonment signal n. This is a circuit for outputting data, and this example circuit is used as the third example circuit.
As shown in the figure.

In Fig. 3, 201.202 is the flinopso 1 knob, 203.204 is the counter, 205 is a part of the starting point, 207 is the impark, and 208.209 is the ann i.

- to be done. When this flip-flop 201 is set, the counter 203 starts operating, and after a certain period of time, the flip-flop 201 is reset to 1-. When the flip-flop 201 receives an incoming call detection signal m from the network control unit 104 while the flip-flop 201 is being turned on, the flip-flop 202 is set, and after the incoming call disappears, a status transmission request signal β is output to the information sending control unit 107. .

When the flip-flop 202 is set to 1, the counter 204 starts operating, and after a certain period of time, the flip-flop 202 is reset and the output of the status transmission request signal β is stopped.

Next, the operation of the device of this embodiment will be explained.

Now, an alarm has occurred on the security terminal device, and a call has been made to send the security information to the alarm reception center, but since there was no response even after making the predetermined number of calls, the terminal device has not sent the message. It is assumed that the alarm has been abandoned, and that there is an incoming call from the alarm receiving center within a predetermined time after this abandonment.

In this case, this incoming call is detected by the network control unit 104 and transmitted as an incoming call detection signal m to the incoming call control unit 10). Since this is within the predetermined clear interval after which the Zunawara counter 203 is operating and the -C flip-flop 201 is in the set state, the status transmission request signal a is output to the information transmission control section 107. The information transmission control unit 107 that received the transmission request signal l outputs the activation request signal l to the network control unit 104.The network control unit 104 that received the activation request signal l automatically dials the alarm reception center, and the alarm reception center automatically dials the alarm reception center. When an automatic call is received, a response signal and a data transmission command are returned.This return signal causes the information transmission control unit 1 to
07 is timing clock f? begins to be sent to the information record 1a section 106. The information storage unit 106 that has received the timing clock f() sends data such as the terminal number to the transmitter/receiver unit 1.
05, "ζ transmission" is carried out via the network control unit 104.

When the alarm reception center receives this data, it returns a consolidation completion signal. Through this series of operations, the alarm reception center can obtain necessary security information and determine whether or not there is a failure in the terminal device.
