[Industrial applications]

 The present invention relates to an illegal intrusion notification device for notifying an unauthorized intruder of the location of the device to a surveillance place via a telephone line, and particularly to a simplified illegal intrusion notification device suitable for temporary use. Regarding

[0002]

[Prior art]

 Conventionally, a device having a similar purpose of this kind has been generally considered to be a system in consideration of long-term use and not operating after being installed once. Therefore, it was relatively expensive, and a little specialized knowledge was required when installing the equipment, and a specialist or a full-time worker was doing the installation work. Then, a sensor for intruder monitoring was screwed to the wall or ceiling, a cable was connected between the attached sensor and the main body, and the cable was stretched to an inconspicuous place such as the floor, wall, or ceiling.

[Problems to be solved by the device]

 However, there are various purposes for installation, and in some cases, short-term monitoring is sufficient. Even in such a case, the conventional device requires a lot of labor and time to install the device, and a general person can operate the device once it has been installed.However, at least the installation and removal should be done by a handling specialist. There was an inconvenience that I had to make a decision and the dedicated person had to do it. In addition, the conventional infrared sensor for monitoring has a narrow angle to be monitored, and one sensor may not be able to cover the desired monitoring range.

The object of the present invention is to solve the above problems, to wirelessly connect the detection unit and the main body, and to simplify the functions of the main body, thereby making it inexpensive, easy to temporarily install, and wide in angle. An object is to provide a simple illegal intrusion notification device capable of monitoring.

【Example】

 Next, the present invention will be described in detail with reference to the drawings. FIG. 1 is a systematic diagram of a system configuration showing an embodiment of the present invention. In this embodiment, as shown in FIG. 1, it comprises a detection unit 10 and a communication control unit 20. In FIG. 1, 1 is an infrared sensor, 2 is a detection control circuit, 3 is a dial tone multi-frequency signal generation circuit, 4 is an FM transmitter, A-1 is a detection side antenna, and A-2 is a communication control side. An antenna, 11 is an FM receiver, 12 is a dial tone multi-frequency signal decoder, 13 is a communication control circuit, 14 is an automatic dial transmitter, and 15 is a voice recording / reproducing device.

The operation of the detection unit 10 side will be described below. First, when the intruder enters the detection range, the infrared sensor 1 detects infrared rays emitted from a person and sends an intruder detection signal to the detection control circuit 2. The detection control circuit 2 sends an activation signal for 5 seconds to the dial tone multi-frequency signal generation circuit 3 and the FM transmitter 4 according to the detection signal from the sensor. The dial tone multi-frequency signal generation circuit 3 is activated by the activation signal from the detection control circuit 2, generates a dial tone multi-frequency signal, and sends it to the FM transmitter 4. The FM transmitter 4 is activated by the activation signal from the detection control circuit 2, and sends the dial tone multi-frequency signal from the detection unit side antenna A-1 as an FM radio wave.

The operation on the communication control unit 20 side will be described below. The FM receiver 11 receives the detection signal from the detection unit 10 via the communication control unit side antenna A-2, demodulates it, and sends it to the dial tone multi-frequency signal decoder 12. The dial tone multi-frequency signal decoder 12 detects the dial tone multi-frequency signal from the received signal, confirms that it is the signal from the detection unit 10, and sends the result to the communication control circuit 13. The communication control circuit 13 receives the signal from the dial tone multi-frequency signal decoder 12, and activates the automatic dial transmitting device 14 and the voice recording / reproducing device 15. Upon receiving the activation signal from the communication control circuit 13, the automatic dial transmission device 14 makes a call to a preset telephone number, and the voice recording / reproducing device 15 sends out a prerecorded notification message to the telephone line.

An example of the method of using this embodiment will be described. FIG. 2 is an explanatory view showing the installation situation of the embodiment of FIG. In FIG. 2, reference numeral 30 is a communication device installation location, 40 is a telephone exchange office, and 50 is a monitoring telephone installation location. C-1 is a connection point of the modular cord attached to the communication control unit 20, and C-2 is a connection point of the modular cord attached to the monitoring telephone set T. In the installation work of the present embodiment, the modular cord attached to the communication control unit 20 is inserted into the telephone line lead-in terminal (C-2) of the building (for example, 50) where the illegal intruder is expected to be damaged, and the detecting unit 10 is connected. All you have to do is place it in an unobtrusive place (such as on the rocker) toward the passage where illegal trespassing is expected. Moreover, although not shown, since a curved lens is attached to the front surface of the infrared sensor 1, wide-angle intrusion detection is possible.

The setting operation of the communication control unit 20 may be a simple key operation or switch operation for registration of a report destination telephone number, registration of a notification message, and notification operation setting. In the case of the present embodiment, the content of the notification message can be registered for about 20 seconds. The power source of the detection unit 10 can be continuously used for about 3 hours by using a dry battery, and the communication control unit 20 normally uses AC100V, but it has a built-in battery and operates even during a power failure. In the circuit of this embodiment, many inexpensive mass-produced parts (infrared sensor unit, FM transmitter kit, FM radio, CPU kit, memory auto dialer, voice recording / playback kit, etc.) are used, and We are trying to reduce the price.

[Effect of device]

 As described in detail above, the present invention uses a wireless connection between the detection unit and the communication control unit, and simplifies the function of the communication control unit, so that it is inexpensive but requires a lot of labor and time for installation. Instead, it has the effect of making temporary installation extremely easy. In addition, by using this embodiment, a dedicated person for installation or removal is not required. Furthermore, by mounting a lens on the front surface of the monitoring sensor, the monitoring range becomes wider, which has the effect of enabling a wider range of monitoring than before.
