Description

[Detailed Description of the Invention] The present invention relates to a reporting device for crime prevention, and is an economical system that can distinguish between the normal handling of the reporting device and the external intruder who is the object of security. The purpose is to provide a reliable reporting device.

Figure 1 shows a configuration diagram of a conventional reporting device, in which information from various sensors (3) connected to a reporting device (2) installed inside a guarded building (1) is transmitted through a telephone line (4). It appears that it will be sent to the security company's seven-terminal. In addition, in this V step 5, the main alarm device (2) is installed indoors and near the outdoor entrance to distinguish the same information from normal residents and external intruders, such as opening and closing of doors and windows for crime prevention. Star F, operating device (61,
It was guarded in a configuration where it was installed independently. In other words, when you live in a building (!), whether it's a business office or a private home, you can use the operating device (5) to alert yourself in order to prevent alerts even if the sensor (3) is activated by opening a door or window. It resets the circuitry so that it does not occur, and at the same time sends a signal that it is not on alert. At a business office, when the door is locked after returning to work at night, and at home, when going out, the alarm reset state is set to the alarm start state and a start signal is sent to the center, and an intruder alarm is sent when the pre-intrusion fence is activated. It has become. However, such a configuration has the following drawbacks.

■ Install the operating device (5) and notification device (2) indoors and outdoors.
Because it is a separate piece of equipment, the price including construction costs is high.

■ There are concerns about the management of the operating device (6) installed outdoors.

■ Especially in ordinary households, if the door is opened without resetting the security when returning home, an intrusion alarm will be sent.

■ Particularly in the case of ordinary households, if unfortunately there is an intruder in the home and the security guard has not arrived yet, the person returning home will not know the situation.

The present invention eliminates the above-mentioned drawbacks and will be described below with reference to an embodiment shown in FIG.

Here, (6) a sensor such as a company intrusion sensor, (7) a sensor operation detection circuit, (8) a first timer, and (9)
-4-titch circuit, QO is the first gate circuit, aυ is the second
, (to) is a buzzer, (2) is a second gate circuit, (b) is a transmission control circuit, and (g) is a key switch.

Next, the details of the operation of this configuration in a general household will be described below. If you are usually at home, use the key switch (2)
The contact point (tSa) is connected in series with the sensor (6), so that even if the sensor (6) is activated, no output is generated from the sensor operation detection circuit (7).

When you go out, turn the key switch to 1 home mode”
When you set “Outside Mode” from , the first timer (8
) works and at the same time sounds the buzzer (2).

[Since this type of reporting device is usually installed at the front door, the first timer (8) is usually set to the time required for the householder to open the front door and close the door. 〕At this time,
The input from the sensor (6) that operates when the front door is opened is sent to the latch circuit (
9), while the first timer (II) is operating, the latch circuit (9) is reset and set to a normal state. After the operation of the first timer (8) is completed, the buzzer (2) stops, and the outgoing signal enters the transmission control circuit axis via the second gate circuit (to), and then passes through the subscriber telephone line* to the center side. is sent to the receiver. A timing chart in this case is shown in FIG. [Second timer] Shu is in one set state due to the output of the first timer (8). ] On the other hand, when the front door is opened when returning home, the input of the sensor (6) is detected by the sensor operation detection circuit (7)K and held by the latch circuit (9), but at the same time the second timer Q
11 is activated and the buzzer (b) sounds. In this case, the output of the sensor signal is prohibited by the first gate circuit 01 during the timer operation time. When the person returning home sets the G-switch Ql) from "outside mode" to "home mode" during the operation period of the second timer Ql), the latch circuit (9) and the second timer (2) is reset,
The sensor at the entrance door does not report human power, but a home signal is sent from the transmission control circuit (b) to the receiver at the center. A timing chart in this case is shown in FIG.

Next, if there is an intruder after setting the out-of-home mode.

While the buzzer (2) operates for the time set by the second timer OP, the first gate circuit 01) is then opened as shown in the timing chart of FIG. 5, and the alarm signal is sent to the transmission control circuit a4. The center will be notified through.

In the above operations, the buzzer @ sounds when the operator ((.

This warning sound can remind you to set the switch (to) to "outside mode - mode 1 to 1" during the ringing period when operating when going out.

A similar message will be applied to an intruder when in "outside mode", but unless the key, which only the householder has, is inserted and the system is set to "at home mode", an intrusion signal will be sent for a certain period of time.

Furthermore, unless you go into "home mode", the latch circuit information (in the event of an intruder bus) is not reset, so if an intruder is unlucky enough to be in your home and your family member returns home and opens the front door before the security guard arrives. Even in the event of an emergency, the buzzer υ does not sound like it would normally, so those returning home can immediately detect an abnormality in the home and protect themselves.

As explained above, according to the reporting device according to the present invention, since the reporting device and the operating device are integrated, it is possible to reduce costs including construction costs, and it can be installed in the home. It is convenient for management because it can be done. Furthermore, it is easy to handle and prevents operational errors by the operator.
