Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a security / security system which is convenient when the security system is in a security set and is to be used for a short trip at night.

[0002]

2. Description of the Related Art In a security crime prevention system used in a general house, when a crime prevention set is used, even if a door such as a front door is opened, the alarm output is delayed for a predetermined time. For example, it is customary that the alarm is not output.

However, in such a system, even when going out for garbage disposal at night set in the crime prevention set, an alarm is output when the crime prevention system is not released at the time of returning. There was a problem of doing. Also, if you cannot return within the delay time of the crime prevention system, you must release the crime prevention system that has been set in advance as a crime prevention set.In such a case, after returning home, do the operation carelessly. I forgot.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and its purpose is to cancel the crime prevention when returning home immediately after going out for a while when in the state of the crime prevention set. It is to provide a security crime prevention system that eliminates the need to operate the crime prevention set again after the operation.

[0005]

The present invention according to claim 1, which is proposed to achieve the above object, provides an entrance / exit detection sensor installed at an entrance / exit such as an entrance or a selfish entrance, and A security crime prevention system configured to combine a crime prevention receiver that processes a detection signal and switches between a crime prevention set and a cancellation state.When the crime prevention receiver is in the crime prevention set, The detection sensor detects that the person is out and when the return home is detected within a predetermined time, the alarm output of the security receiver is prohibited.

According to the present invention as set forth in claim 2, when the crime prevention receiver is in the crime prevention set state, and when a person's going out is detected by the entrance / exit detection sensor, the crime prevention receiver is temporarily released from the crime prevention. When the return home is detected within a predetermined time, the crime prevention receiver is configured as a crime prevention set. The entrance / exit detection sensor emits infrared rays generated by the human body in addition to a pair of transmitted light type sensors.
A structure has been proposed in which the reflected light is detected to detect the entrance and exit of a person (claim 3).

[0007]

In the security crime prevention system according to claims 1 and 2, when the exit / entry detection sensor detects that the person is out, the internal timer starts counting the time, and the person's time is set before the preset predetermined time elapses. When the return home is detected, the security receiver does not output an alarm, so it is not necessary to bother to release the security set and then immediately operate the security set.

Further, if an infrared ray sensor is adopted as the entrance / exit detection sensor proposed in claim 3, the detection accuracy, controllability, and simplification of the structure can be obtained, which is convenient.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram showing a security crime prevention system of the present invention. In this system, two sets of first and second entrance / exit detection sensors 3 and 4 installed at entrances and exits such as entrances are connected to the security receiver 2 installed at appropriate places in the house 1. The alarm buzzer built in the security receiver 2 is activated based on the output / incoming detection signals from the first and second in / out detection sensors 3 and 4 to output an alarm.

The first and second entrance / exit detection sensors 3, 4
Is a transmissive type in which a transmitting medium and a receiving side of a detection medium such as light, infrared rays, and ultrasonic waves are separately opposed to each other, and the signal processing unit 10 connected to both sides detects a cutoff. Based on the order in which the signals are detected, the passing direction of a person is determined and the entrance / exit is detected. That is, as for the case of a family member, if the first entrance / exit detection sensor 3 outputs the detection signal first and the second entrance / exit detection sensor 4 outputs the detection signal later, it is determined that the person is out and in the reverse order. If there is, it is judged to be home. The signal processing unit 10 is not indispensable, and instead of this, a CP for signal processing provided in the security receiver 2.
The above determination may be performed by U (not shown) or the like.

Further, instead of the above-mentioned transmission type first and second entrance / exit detection sensors 3 and 4, as shown at 15 in FIG. 5, the projected infrared rays are received by two receiving beams, and the infrared rays are reflected respectively. A double-beam infrared sensor, which has the function of identifying the moving direction of the detected object by detecting the change in light, is used as an entrance / exit detection sensor. It may be installed toward.

If such an infrared sensor is used,
Compared with the case where the transmission type first and second entrance / exit detection sensors 3 and 4 are adopted, the control is relatively easy and the detection is accurate, and the installation can be facilitated due to the simplification of the structure. Benefits are obtained. Next, the operation of the security crime prevention system of the present invention will be described. As is apparent from the time charts shown in a) to e) of FIG. 2, when the crime prevention receiver 2 is in the crime prevention set state, one set of the first and second access detection sensors 3 and 4 is used. When it is determined that the family member is going out by the detection signal, the security receiver 2 does not output an alarm at this time, activates an internal timer (not shown), and sets a predetermined time t (for example, 1 minute). Or 2 minutes).

If it is not determined that the housekeeper has returned home by the detection signals of the first and second entrance / exit detection sensors 3 and 4 before the predetermined time t has passed by the internal timer, the crime prevention receiver 2 is internally operated. An alarm is output in response to the count-up signal from the timer, but before the internal timer counts up, the first and second access detection sensors 3, 4
The alarm output is prohibited when it is determined that the family member is going home by the detection signal of.

Before the elapse of the predetermined time t,
When the detection signals from the first and second entrance / exit detection sensors 3 and 4 indicate the going-out direction, the internal timer should be restarted at this point, or an alarm should be issued immediately at this point. It may be appropriately changed according to the embodiment such as whether to output. However, before a predetermined time t has elapsed and only one of the first and second entrance / exit detection sensors 3 and 4 transmits a detection signal, or after the predetermined time t has passed. Then, it is preferable that the security receiver 2 immediately outputs an alarm.

3 and 4 are flowcharts showing the operation procedure of the security crime prevention system of the present invention. Steps 100 to 106 in FIG. 3 correspond to claim 1, and after the detection of going out. , When the internal timer is set, the crime prevention set is kept as it is at the same time as the operation, and waiting for return detection (steps 101 to 1)
03, 105), and steps 200 to 208 in FIG. 4 correspond to claim 2. After the detection of going out, once the crime prevention set is released, the detection of returning home is waited for.
It shows how to return to the crime prevention set when returning home.

As can be seen from these time charts, naturally, in the case of FIG. 4, the crime prevention setting is automatically performed again after the time is up, and an alarm is output when an abnormality is detected. By the way, in this embodiment, as shown in FIG. 1, the security receiver 2 is an operation unit for comprehensively managing the house 1 in various directions by monitoring other various sensors. For the crime prevention receiver 2, a window opening / closing detection sensor 5 provided in the window 12, a door 11 such as a front door or a door opening 13 and a door opening detection sensor 6 provided in the door 13 as well as a range stand 14 etc. Gas leak sensor 7 and fire detection sensor 8 arranged as
The emergency button 9 and the like are also connected. Therefore, an alarm is output when a detection signal from these various sensors or a button operation is received.

The window opening / closing detection sensor 5 has a magnet on the window 12 side and a reed switch on the window frame side, a reflector on the window 12 side and a proximity switch on the window frame side, or the window 12 side. An appropriate one such as one having a cam-shaped protrusion on the side and a limit switch on the window frame side is used. The door opening detection sensor 6 is similar to the door opening detection sensor 5 and the operating state of the electric lock. What can be judged is used.

[0018]

As can be understood from the above description, according to the security crime prevention system according to the present invention, when the security set is in the state, the crime prevention reception is carried out when going out for a short while and going home immediately. Since the machine is configured to prohibit the alarm output, there is no need to perform the crime prevention release operation or the crime prevention set operation again thereafter, and the trouble and troublesomeness can be eliminated.
