Abstract

PURPOSE:To grasp the trepass route of a trepasser by displaying 'information indicating detection order' additionally to the installation position formation of a detecting means which detects the presence of the trepasser. CONSTITUTION:When the trepasser enters a building, detecting means S1-S3 detect that and outputs detection signals to a control means 11 and when the trepasser moves in the building, detecting means S4-S6 installed at respective places in the building outputs detection signals to the control means 11 similarly. The control means 11 once supplied with the detection signal accesses a registration table 13 to read the installation position information on the corresponding detecting means S1-S6 and writes the read installation position information and additional information indicating the detection order in a display memory 22 successively. The contents written in the display memory 22 are outputted to and displayed on a monitor display 14. Consequently, the trepass course of the trepasser can be grasped.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to building management technology for disaster prevention and crime prevention, and particularly relates to a crime prevention monitoring system for commercial buildings.

<Conventional Technology> Commercial buildings containing many stores, such as department stores, are equipped with various security equipment.

One of them is a security monitoring system. What is well known is that a monitoring panel is installed in the central monitoring room where security guards are stationed, and sensors that detect the opening/closing status of entrance/exit doors on each floor of the building are installed at various locations within the building. A system that lights up a warning lamp on a surveillance panel in response to a detection signal from a sensor that detects illegal entry, or a system that installs a monitor TV in addition to the surveillance panel and uses a television camera that takes pictures of the inside of the building. This is a system that displays images on a TV monitor.

Crime prevention measures are taken in such a way that when a lamp on the monitoring panel indicates an abnormality, some of the security guards stationed in the central monitoring room rush to the abnormal area and check the situation. .

<Problem to be solved by the invention> In buildings where the above-mentioned crime prevention monitoring system has not been introduced, or in buildings where it has not been introduced yet, crime prevention measures such as having a large number of security guards patrol and monitor the building in shifts are necessary. One of the purposes of the crime prevention monitoring system is to save the manpower required for security.

However, as with the above-mentioned crime prevention monitoring system, it is difficult to understand the intrusion route of an illegal intruder by simply notifying the intruder by lighting a lamp, which saves the manpower required to track the intruder. The disadvantage is that it cannot be expected to change.

This is because the lamps on the monitoring panel turn on randomly depending on the destination of the trespasser, and after many lamps have been lit, it is not possible to grasp the elapsed time of lamp lighting. Moreover, it becomes difficult to understand the route of intrusion by illegal intruders.

Understanding the intrusion routes of illegal intruders not only saves manpower, but also provides useful information for future crime prevention measures, which cannot be obtained with conventional systems. There is also a disadvantage.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a crime prevention monitoring system that can grasp the intrusion route of an illegal intruder.

<Means for Solving the Problems> In order to achieve the above object, the present invention has the following configuration.

That is, the crime prevention monitoring system of the present invention includes a detection means installed at various places in a building to detect the presence of an illegal intruder;
A registration table in which at least the installation position information of each of the detection means is registered in advance, and information indicating the detection order by reading out the installation position information of the corresponding detection means from the registration table in response to a detection signal from the detection means. The present invention is characterized by comprising a control means for adding and writing the contents of the display memory into the display memory, and a monitor display for displaying the contents of the display memory.

<Effect> The effects of the present invention are as follows.

When an illegal intruder enters the building, the detection means detects this and outputs a detection signal to the control means.

Furthermore, when the trespasser moves within the building, each detection means installed throughout the building similarly outputs a detection signal to the control means.

When the control means is given the detection signal, it accesses the registration table and reads out the installation position information of the corresponding detection means. Information j indicating the detection order is added to the read installation position information and sequentially written into the display memory.Then, the contents written to the display memory are output and displayed on the monitor display.

In this way, information indicating the detection order is added to the installation location information of the detection means that detects the presence of an illegal intruder, so it is possible to display the information in which order the illegal intruder moved within the building. In other words, the route traveled is presented on the monitor display.

5゜Magnetic disk for recording the true news situation 16. A printer that outputs the true news situation as a printed matter 17. It is equipped with a communication modem 18 and the like for transmitting real news status.

The sensor information registered in the sensor registration table 13 includes the terminal number of the terminal block 4a to which each sensor 31 to S6 is connected, the type of each sensor 51 to S6 (for crime prevention or equipment), and the installation floor. , installation location (inside/outside the building), content (outline of objects detected by the sensor), and five types, etc. When each sensor 31 to S6 is installed,
It is created manually using the operator's keyboard 15 and registered in the sensor registration table 13. An example is shown in FIG.

The communication modem 18 connects the control center 20 and the personal computer body 10 via the communication cable 19, and when each sensor 31 to S detects an abnormality, it reports the abnormal situation determined by the CPU Ull to the control center 20. It is.

The control center 20 is a place that centrally manages crime prevention for multiple buildings, and has the function of, for example, notifying security guards of nearby buildings when a true alarm is received from a relatively small and unoccupied building. .

Next, the display of the intrusion route, which is a characteristic part of the present invention, will be explained based on the flowchart of FIG. 3 showing the processing procedure of CP Ull.

First, in step S1, various mode settings (status settings of the crime prevention monitoring system) specified by the operator are input. An example of the types of modes to be set is given below.

■Monitoring mode: This is the mode in which the security monitoring system functions, and security sensors S, S2. S.

This refers to the state in which the output from the device is received. Note that the outputs from the equipment sensors S, SS, and S6 are always on. In the case of a commercial building, this mode is canceled while each store is open, and set after the store is closed.

■Notification mode: Under monitoring mode, when an abnormality occurs,
Abnormal situation display on monitor display 14.

Displays the intrusion route.

■Alarm mode: In addition to the action in notification mode, abnormal situations are reported to the control center 20.

■Camera switching mode: The direction of the monitoring television camera 6 is set to the installation position of the sensor that detected the abnormality.

After inputting the settings for the various modes described above, the process proceeds to step S2, where it is determined whether the monitoring mode is set. When each store is closed and the operator sets the monitoring mote, security sensors S, S2 . S
, enters the "ON" wait state.

Here, it is assumed that a sensor installed along the east wall of the outer periphery of the first floor, for example, an infrared sensor S3, is in the "ON" state. The detection signal of sensor S3 is output to terminal block 4a. When the sensor S3 is connected to the terminal Nα1 of the terminal block 4a, the detection signal of the sensor S is given from the terminal Nα1 to the multiplex unit yXc. In response, the multiplex unit 4C sends identification signals of terminals No. 1 to the multiplex transmission line 5.

When the identification signal from the multiplex transmission line 5 is input, step S
In Step 3, it is determined that the sensor is in the "ON" state, and in Step S4, a BEEP sound (a sound emitted from the computer body 10, and the components for sound generation are added to a normal computer, so illustrations and explanations are omitted. ), and in step S5, the form of the abnormality report screen stored in advance is transferred to the VRAM 22. And VRAM22
The content of is output to the monitor display 14, and the display screen of the monitor display 14 is switched to an abnormality reporting screen.

A display example of the changed abnormality reporting screen is shown in the fourth bacterium.

In step S6, the sensor registration table 13 is read, and in step S7 it is determined whether the sensor that has become "ON" is a security sensor or an equipment sensor.

That is, from the identification signal of the given terminal Nα1, sensor registration table 1 is created using terminal No. 1 as a keyword.
3 (see Figure 2), read the input items of the sensor registered on terminal floor 1, and if it is registered as "crime prevention", proceed to step S9 and subsequent steps, and select " If "equipment" is registered, the process moves to step S8.

In this example, since "Crime Prevention J" is registered at the terminal Nα1, the process advances to step S9.

In step S9, the contents of the timer counter 21 (real time information), the type of mode setting, and the sensor registration table 13 are
One type of input and content information of the terminal Nα1 registered in the terminal Nα1 is extracted and transferred to the VRAM 22.

At this time, the write address of the VRAM 22 is specified so that this information is displayed at a predetermined position on the monitor display 14. Then, the contents written to the VRAM 22 are displayed on the monitor display 14. As a result, as shown in Figure 4, '20:13, notification, crime prevention, IF
Along the east exterior wall, the text string ``Infrared rays'' will be displayed in a predetermined position.

In step S10, information on the installation floor and installation location registered in the terminal NQI (corresponding to installation position information) is extracted, and an "arrow symbol" as information J indicating the detection order is added to the information.
is added and transferred to the VRAM 22. At this time, the VRAM 22 is configured to display this information on the intrusion route display 11i1 (in this example, the blank field at the bottom of the abnormality reporting screen).
The write address of is specified. Then, the contents written to the VRAM 22 are displayed on the monitor display 14. As a result, as shown at the bottom of the screen in FIG. 4, the character string "rF 1st floor outer periphery →" and the "arrow symbol" are displayed at a predetermined position.

In this way, security sensors S, , S2. S3 is “
When the state is “ON”, the information of the corresponding sensor and
Intrusion route information with an arrow symbol added to the floor and location where the sensor is installed is displayed.

After the display, the process proceeds to step Sll, and it is determined whether the input mode setting is the above-mentioned camera switching mode. If the camera switching mode is set, the process advances to step S12.

In step S12, the identification signal of the sensor connected to terminal No. 1 is sent to the camera control section 7 and the illumination control section 30 via the camera switching box 8. Camera control section 7
controls the television camera 6 to face the sensor position, and the lighting control unit 30 turns on a light 31 installed on the ceiling or the like at the sensor position.

Furthermore, the process proceeds to step SI3, and if the input mode setting is the above-mentioned ■alarm mode, the abnormal situation (contents displayed on the abnormality notification screen) is reported to the control center 20 via the communication modem 18. (step 514).

Then, in step SI5, it is determined whether the next sensor is in the "ON" state in the same manner as in step S3, and if it is in the "ON" state, the processes from step S7 onwards are repeated.

In this example, for the sake of explanation, it is assumed that the next sensor is an equipment sensor that is in the "ON" state.

Step S7 moves to step S8, and step S9
In the same manner as above, the information of the activated sensor is displayed on the monitor display 14. This is the result of displaying '20:45, notification, equipment, IF circulation pump, electric motor' in Figure 4.

Also, if the next sensor is a security sensor, intrusion route information will be displayed along with the sensor information each time.
It is possible to understand the intrusion route of illegal intruders. Each piece of information about the displayed abnormality report is saved by being recorded on the magnetic disk 16 or printed by the printer 17.

The next sensor does not turn on, and the operator
Determine that end command J has been input (step S)
6), the process returns to step S], and if the monitoring mode is continued, the process enters the sensor "ON" wait state in step S3. If the monitoring mode is canceled at the opening time of each store, etc., the system enters a monitoring mode standby state in step S2.

In addition, in the embodiment described above, in order to display the intrusion route,
Although a display format in which the floors and locations of sensors are connected with arrows has been exemplified, the display format is not limited to this, and various display formats may be adopted.

For example, the floor plan of each floor may be entered in advance, and when the security sensor is turned on, the intrusion route may be displayed by connecting the sensor positions on the floor plan with line segments. .

In this case, a "line segment" connecting the positions of each sensor corresponds to "information suggesting the detection order."

<Effects of the Invention> As is clear from the above description, the crime prevention monitoring system of the present invention adds "information J indicating the detection order to the installation position information of the detection means for detecting the presence of an illegal intruder," Since this is displayed, the operator (security guard) can check on the monitor display the order in which the trespasser moved through the building, in other words, the route taken by the trespasser. can do.

Therefore, it is possible to save the labor of patrol personnel and personnel to track illegal trespassers, which were required in the past.Also, since it is possible to understand the intrusion route, useful information can be obtained for devising crime prevention measures, and future crime prevention. This can contribute to strengthening countermeasures.
