Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to an intrusion monitoring device that generates an alarm when there is an intrusion from the outside within a range to be monitored.

[Technical background of the invention and its problems] Figure 2 shows a system in which a plurality of intrusion sensors 3 are installed around a building 1 in order to monitor and protect an important facility or building 1 from intrusion from the outside. It is a double arrangement. The area around the building 1 to be monitored is divided into a plurality of sections, and the sensor 3 is arranged for each section, so that each sensor 3 monitors the corresponding section. In addition, by arranging the sensors 3 in duplicate, intrusion can be monitored more completely, and the degree of intrusion and intrusion can be determined, for example, if the outer sensor detects an intrusion but the inner sensor cannot. It is now possible to identify and distinguish the proximity of each other.

FIG. 3 shows a reception processing device 7 consisting of a conventional sequencer or relay circuit that receives signals from sensors arranged as shown in FIG. 2, processes them, and supplies them to the monitoring panel 5. It is something that exists. This reception processing device 7
receives detection signals from each sensor divided into sections and arranged in duplicate in a time-division manner, analyzes and processes the signals into a light alarm signal and a heavy alarm signal, and supplies the signals to the monitoring panel 5.

That is, the reception processing device 7 receives the infiltration detected temperature @SX! from the sensor placed inside, for example, when receiving the section i. and an intrusion detection signal Syi from a sensor placed outside. Then, when the reception processing device 7 receives both the signals 3xi and Syl, that is, when the intrusion is detected by both the dually arranged sensors, the reception processing device 7 receives the heavy alarm signal @3.
ai, and the reception processing device 7 outputs the signal Sxi or Sy.
If only one of the signals of l is received, that is, if the intrusion is detected by only one sensor,
It is designed to output a light warning signal of 3bis.

By the way, in such a conventional reception processing device 7, the detection signals from each sensor divided into sections are all time-divisionally received and processed by one common reception processing device 7. In a typical intrusion monitoring device, the range to be monitored is changed or added depending on changes in various situations. Therefore, in the reception processing device 7 configured as described above, it is necessary to change the wiring or add sensors and other parts every time such changes or additions are made. There is a problem that it cannot respond to changes and expansions.

Furthermore, the above-described configuration has a problem in that in the event that the reception processing device 7 fails, intrusion monitoring of the entire area cannot be performed.

[Purpose of the Invention] This invention was made in view of the above circumstances, and its purpose is to easily cope with changes and additions to monitoring areas, and to prevent the occurrence of situations in which monitoring is not possible for all areas. An object of the present invention is to provide an intrusion monitoring device that prevents.

[Summary of the Invention] In order to achieve the above object, the present invention divides a predetermined range to be monitored into a plurality of sections, provides a sensor for detecting intrusion from the outside in each section, and detects a signal from the sensor. The gist of the present invention is that a plurality of reception processing devices for receiving the information and monitoring for intrusion are provided independently corresponding to each section.

[Embodiments of the invention] Next, embodiments of the invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.

In the figure, a reception processing device 9i ('l-1, 2, 3...) receives and processes detection signals from each sensor 3 for each section i (i = 1.2.3...) In addition, each section 1 receives an intrusion detection signal 3xi from the sensor 3 placed inside the sensor network arranged in two sets, and an intrusion detection signal 3xi from the sensor placed outside. The intrusion detection signal Syi is supplied to each reception processing device 91 corresponding to section i.In each reception processing device 9j, when both signals Sxi and Syl are received, that is, intrusion is arranged doubly. When detected by both sensors, a heavy alarm signal 3ai is output, and when only one of the signals S×i or Syi is received, that is, when intrusion is detected only by one sensor. , the light alarm signal Sbi is output.Then, the heavy alarm signal 5att from each reception processing device 91 is output.
'3 and the light alarm signal Sbi are supplied to the monitoring panel 5,
Here, for example, an alarm is generated to notify of an intrusion, and
It is designed to display various information such as the location of the intrusion.

In the intrusion monitoring device configured as described above, when the monitoring area is determined, this monitoring area is divided into several sections, and the reception processing device 9 is installed in the number of sections corresponding to each of the divided sections. Install and monitor. Even if the monitoring area is changed or expanded after that,
This does not affect other reception processing devices 9 that have not been changed, and it is possible to respond to changes or increases in the area by simply adding or deleting reception processing devices 9.

In addition, in the above embodiment, the case where the sensors are arranged double is explained, but the invention is not limited to this.
The present invention can be applied to triple-layered structures and various other structures.

[Effects of the Invention] As explained above, according to the present invention, since the reception processing device is independently provided corresponding to each section, even if the monitoring area is changed or expanded, the change will not be affected. Other reception processing devices that are not required will not be affected at all, and you can easily respond to changes or increases in the monitoring area by simply adding or deleting new reception processing devices, and the related installation Construction will be easier and faster, and construction costs will be lower.

In addition, since the reception processing HMs are provided independently, even if one reception processing device fails, it will not affect the reception processing device for the song, preventing the unmonitored state from extending to the entire monitoring area. can.
