A reception processing means processes the fr9 signal and reflects it on a code signal similar to the code haiku input from the cable (8), and a code from each code ilgo window yohi cable (8) output from the processing membrane. The J+41 is a receiver/decoder (a computer into which the 13th valley E code data is input, forms a monitoring processing means, and is equipped with a Target map data, 25 and valley sensor fil~

Based on the data and monitoring processing program, an approach or intrusion is detected and generated.

In addition to determining the route, type, and direction of the approaching or intruding object (hereinafter referred to as a suspicious object), all inferences are made such as the suspicious object's expected future course and target location, and the determination results and inferences are displayed on the map. A display signal of an alarm screen obtained by displaying the result is outputted to the ML monitor television forming the screen display means.

Based on the control of the camera (9), which is a video processor that processes all video signals from the Hv, the camera (9) is fully controlled via the cable Qll, and the camera (9) is operated by the cable αG? The screen display number ζ of the video signal is output to '@2 monitor television +171.

will be processed.

Further, the sensor (31) includes a sensor that detects both a person and a vehicle, and a sensor that detects only a two-wheeled vehicle.

The sensors fll~+51 have, for example, the performance shown in the following table, and for example, the sensor 21. +31 is buried underground, and other sensors fi+, +4
1. The lfi+ is installed on the ground so that it is not easily seen, and at this time, it is possible to detect the approach of the target outdoor area, detect intrusion, and distinguish between quarrels, etc. from the detection signals of each sensor 11 to 61. They are rearranged at relatively narrow intervals.

Furthermore, the processor (61, feed IN (7), cable (8)
, antenna (121 forms signal transmission means, processing t
The ta+, transmitter, and transmitter (7) are installed underground.

The detection signals of the sensors fi1 to (51) are constantly transmitted to the receiver/decoder (13) by wireless transmission through the processor or wired transmission via the cable +81'f!:.

Just in case, the decoded data of the detection signals of each sensor fil~(6) is sent from the receiver/decoder Q31 to the computer fi41.
For example, each sensor is assigned a number and output.

Furthermore, based on each decoded data input to the computer t14, the basic data, and the monitoring processing program, the approach or intrusion of a suspicious object is monitored, and when there is no approach or intrusion of a suspicious object, the A display signal of a map of the security target is output to a51.

When a suspicious object approaches or intrudes, the computer
I41 detects all approaches and intrusions from the decoded data of the detection signals of valley sensors [11 to (61), determines the place where the hot water occurred, and immediately displays the screen of the TV (151).

Based on the audio output from a speaker outside the area, the time of occurrence in the area 0 of the hot water area is displayed, a sound is output, and an initial warning is issued.

Furthermore, the decoded data of the detection signals of the sensors f11 to (6) is accumulated in the computer 114 in 111 units, and based on the combination of changes in the accumulated decoded data, the computer circle detects the suspicious W body. In addition to determining the type, i.e., proboscis, vehicle, noise, speed, and direction of travel, it also determines the route of approach and intrusion, and displays the results of this determination on a map and displayed on the TV (16). let

At this time, on the ufi+'@ of the television (1b), the type and direction of the suspicious object are shown on the map using nine letters and figures, and the route thereof is displayed, for example, as a red line.

Furthermore, the computer 04 infers the expected future course of the suspicious object, the target location, etc. based on the route determination result and, for example, the layout of each structure in the facility, type 1 deviation, etc., and uses the result of guess #B. For example, if you want to know the course etc. on TV (1) in green,
5).

Furthermore, when the non-fF object arrives within the field of view of the camera (9), the operator 114) commands the processor H to display a photograph, and the camera (9) is fully activated and the television (one camera) is activated. Display the shooting screen of the camera (9).

By the way, when you operate the keyboard of the computer Q41 to command printing, the printer α~ prints the TV+15
1 screen, or a character 1 figure of a discrimination or inference result, etc., is created.

Further, in special cases, the computer Q41 determines the type and number of unwound objects and displays them on the television Q51 by selecting a processing mode based on, for example, a thousand-board operation.

Therefore, in the case of the above embodiment, the small sensors fil~(6) are used to monitor approach and intrusion, and moreover, the sensors 121. f31 and processor (61, transmitter (7
), the cable (8) is buried underground, making it possible to reliably monitor the approach and intrusion of suspicious objects in an extremely discreet manner.

In addition, based on the detection 2 discrimination and inference of the computer Q41, the type and speed of suspicious objects are detected, which was previously impossible.

Not only can you know the direction of movement, approach, and progress of intrusion, you can also know the expected course and target location, and what's more, the identification and inference results are displayed and announced in an easy-to-understand manner on the TV (16). Therefore, all measures can be taken quickly and accurately.

Moreover, when a suspicious object arrives within the field of view of the camera (9), the suspicious object will be displayed on the TV f+71, allowing you to visually confirm the suspicious object. It is also possible to create a hard record fdk of , approach, and intrusion.

3. In the embodiment described above, the detection signals of the sensors i11 to (41) were transmitted wirelessly, and the detection signals of the sensor (6) were transmitted by one line, but the detection signals of all the sensors fi1 to (6) were transmitted by wire.

In the case of wired transmission, it is possible to omit the reception processing means of the transmitter (7) and receiver (13), and in the case of wireless transmission. The cable (8) can be completely omitted.

Furthermore, it goes without saying that the number and type of each of the sensors (1) to (61) may be arbitrarily set depending on the size and characteristics of the object to be guarded.

By the way, in addition to using the stationary monitoring device i11' (j), in Fig. 2, the same symbols as in No. 1 (2) indicate the same or equivalent items.

The monitor (19) is driven by a primary or secondary battery, etc., and the radio waves from the transmitter +73 of each sensor ill~(4) are received by the antenna ■, and the received signal of the antenna (7) is input to the monitor head. be done.

At this time, the monitor (1g!) includes a computer having all or part of the functions of the computer circle shown in FIG.
A display for the determination and inference results, such as a liquid crystal display, is provided to monitor the detection status of each of the sensors 111 to 41, and to display an alarm for the determination and inference results.

【Effect of the invention〕

As described above, according to the outdoor security device of the present invention, instead of the conventional TV camera and wires, various sensors are used all around the sensor, and the detection signals of each sensor are transmitted to the monitoring device by wire or wirelessly, and the monitoring processing means is installed. In addition to detecting approach and intrusion, it also detects the type of object and the direction of movement, something that could not be done conventionally.

By discriminating the 8-way route and displaying the discrimination result in J blue on the gold map, monitoring can be carried out in a way that is less conspicuous, and detailed information can be displayed in an easy-to-understand manner. It is possible to reliably monitor the approach or intrusion of suspicious objects and take prompt and appropriate countermeasures.
