Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alarm transmitting device, and particularly to a security information signal transmitting device installed in small-scale companies and ordinary homes.

Conventionally, this type of alarm transmitting device was placed in a security area surrounded by senna, and after the person exited the security area, the alarm transmitting device itself was activated by remote control to start security. Follow [You must prepare a separate, robust key box for this remote control,
There were problems in terms of cost, increased construction costs, and the selection of the installation location taking into account aesthetics, prevention of destruction, etc.

In addition, as a form omitting the key box, it is difficult to first set the alarm sending device to the security start state, then calculate the time it takes to exit the security area, for example, to the entrance, and then select the sensor alarm effectively after a certain period of time. However, there was a drawback that it caused false alarms regarding burglar intrusion alarms.

An object of the present invention is to solve the above-mentioned drawbacks of the burglar intrusion alarm by activating the alarm after a certain period of time after detecting the first intrusion, so that the security start operator can go outside. An object of the present invention is to provide a device that can eliminate false alarms.

Regarding the configuration of the present invention, the present invention relates to an alarm transmitting device that detects the occurrence of fire, gas leakage, burglary, etc. and automatically transmits an alarm to a receiving center. A detection section detects the input signals from the loops a1 to an, converts them to logic levels, and sends out the mouth/jick repai signals to the output lines b1 to bn corresponding to the respective sensor loops; A signal processing section that outputs a logic level signal from an output line corresponding to each input signal line, and an automatic dial that automatically dials various necessary information to the reception center based on the input signal of each input line from this signal processing section. and a flip 7 connected to the output line b1 assigned to thief intrusion.
Only the 0 tsug is configured to operate and output for the first time by the second and subsequent inputs using a bypassed flip-flop, a timer, and the other 7 resop-flops,
After the security start is set, the alarm transmitter immediately sends out an alarm in the event of a fire outbreak, gas leak, etc., but in the event of a burglary, the alarm is sent out after a certain period of time has elapsed.

Hereinafter, the present invention will be explained by way of examples with reference to the drawings.

FIG. 1 is a block diagram of the entire alarm transmission system according to the present invention. In FIG. 1, an alarm transmitting device 100 processes sensor loops a, -a, and (f) inputs and reports them to a receiving center 110 via subscriber telephone line 1°30. At the reception center 110, a supervisor constantly monitors the report and, in response to the report, is dispatched to the security light of the alarm transmitting device.

This alarm transmitting device 100 includes a detection section 101 and a signal processing section 1.
02 and an automatic dialing section 103. The detection unit 101 is a normal senna signal detection unit and converts the sensor loops a1 to in to open/shut logic levels. There are also senna signals that are modulated and input via power lines, but in these cases they are demodulated and converted to logic levels.

In the present invention, the detection section 101 may be a conventional detection section. The detection unit 101 outputs the logic level corresponding to the sensor loop 88 to the signal processing unit 102 via outputs 1mbl to bn. The signal processing unit 102 outputs lIb
Recognizes the logic level signals of 1 to bn, outputs the logic level signal to the automatic dial unit 103 via the output corresponding to the cough output line *ct-wcn, and activates the automatic dial unit 103 to the activation signal line Cr. Outputs a signal to However, the input line corresponding to the intrusion alarm will not be used until a certain period of time has passed after the first input of the intrusion loop 11 is recognized.
The logic level input of is ignored, and although it is desired to output nothing to the output line C1, the configuration is such that it is also output to c after a certain period of time has elapsed. The automatic dialing section 103 is connected to the activation signal line Cr.
The receiving center 110 connected by the subscriber telephone circuit 130 is automatically dialed by the DP or FB double signal according to the pre-stored telephone number of the center, and the output line CI%C is activated by the activation signal of A signal corresponding to the output alarm and the unique address of the alarm transmitting device 100 are transmitted to the receiving center 110. Is the transmitted signal a PB double signal or a subscriber phone line? 5130 is a modulated signal within one permissible ripple frequency band. After the transmission is completed, a transmission method signal is output to the signal processing unit 102 via the transmitted signal line Cp, and the signal processing unit 102 returns to the initial state by the error signal.

The internal configuration of the signal processing section 102 in FIG. 1 is shown in a block diagram as shown in FIG.

P (215), a set switch (221), a reset switch (220), three human forces θB (214), and pull-down resistors r, to r3. The security information outputted from the input lines ~bnVc from the detection unit 101 is connected to the set terminals of the 7 lip-flops 2B1~28n for loops.
And the intrusion loop input line b1 is connected to the other intrusion FF1 (2
11) is also connected to the set terminal.

The set switch (221) is set to F when security starts.
F (215) Nosey ) 1111 Vccl to child 111
ll, t +5v or +12V). The state in FIG. 2 is that security is being released, and the signal processing unit 102 has a special temperature F F (2B1 to 2Bn, 211.21
3.215) The beam is in the KY state and the output line -b
Information on all degrees Celsius is ignored. Now set switch (2
21) is brought into the security start state, the activation signal line CrK activation signal is output, and the reset of all FFs except the intrusion loop FF (2B1) is released. If intrusion information is input to the intrusion loop input line b1 in this state, the intrusion FF
l (211) is set, timer 2 (212)
is activated, and after a certain period of time, 1 for intrusion? F 2 (21
3) Set. By setting cough FP,
The reset of the intrusion loop FF (2B1) is released, and the intrusion security information that enters the input line thereafter becomes valid.

When intrusion information is input to the input line for the intrusion loop for the second time, 2B1 of the FF for the intrusion loop is set, timer 1 (210) connected to the Mukuro flip 70 tube is activated, and after a certain period of time, the input line is input to the output line C8. Output logic level as intrusion information. Before the certain period of time has elapsed, press the reset switch (2
20), the timer 1 (210) is reset and no output is output to the output line C1. This is provided to distinguish between a family member returning home and true intrusion information.

When the automatic dial section 103 finishes transmitting information after outputting the information to the output lines C1 to Cn, the dial section 103 outputs a transmitted signal (pulse) to the transmitted signal line Cp.

As a result, the loop 7 lip 7 in the signal 1 signal processing section 102
The Gl, l pins (2B1 to 2Bn) and the intrusion FFs (211° and 213) are all reset, and the signal processing unit 102 enters a state of waiting for input l1Ibl-bn. As a result, only the intrusion information becomes valid after a certain period of time after the first intrusion information, and other loop information (for example, fire outbreak, gas leak, etc.) becomes valid immediately after the start of security.

As described above, according to the present invention, by configuring the signal processing section as shown in FIG. 2, there is an effect of preventing false alarms regarding intrusion by an operator or the like at the start of security.
