CONSTITUTION:Switches 4 are set in areas 1, 2, 3... as patrol confirming means to output when the patrolman to patrol the plural areas 1, 2, 3... in a building in a prescribed sequence performs a prescribed operation. A patrol operation is confirmed by a signal when the patrol confirming means 4 are operated in the areas 1, 2, 3... and when the sensor 4 issues the detection signal in the area apart by a beforehand specified distance or above from the prescribed route while patrolling, when the detection signal is issued in a fixed number of areas or above, or when a prescribed patrol termination operation is not performed within a prescribed time from when the patrol is started, it is processed as the alarm.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention provides a method for patrolling a plurality of areas in a building along a predetermined route,
The present invention relates to a patrol alarm method for issuing an alarm when an abnormality is detected, and an equipment for implementing the method.

[Prior Art] For example, in a building such as an office building, an alarm device or a management device is used that monitors the situation using a monitoring device that includes various sensors placed at appropriate locations, and issues an alarm when an abnormality is detected. ing. Generally, such alarm devices are installed in the control room of a building, and when sensors placed at the entrances, exits, windows, etc. of each room in the building detect an abnormality such as an intrusion into the room, they issue an alarm or take other actions. If the building is constantly monitored, alarms may be issued for situations that frequently occur on a daily basis (for example, workers passing by), which can be more of an inconvenience when there are workers inside the building. become. Therefore,
The alarm device can be switched between an alert state and a non-alert state. Specifically, during times when workers are present, situations that occur frequently, such as people entering and leaving the room, are set to a non-alert state in which detection signals from sensors are ignored. For example, only at night), a warning state is set in which an alarm is generated in response to an abnormality detection signal.

Therefore, the alarm device is equipped with a manually operated switch, and the guard operates the switch to switch between the alert state and the non-alert state.

On the other hand, there is also a security method (referred to as a "patrol tour") in which security guards patrol multiple areas within a building following a predetermined route at night. Therefore, in addition to switching the entire building from an alert state to a non-alert state, the management device monitors the patrol start time and end time, as well as the time taken to move from one area of the building to the next. Ta.

[Problem to be solved by the invention 1 However, in such conventional patrolling methods, the entire building is placed in a non-alarmed state, so areas far away from the area where the patroller is located are not monitored, making it difficult for intruders to enter the building. There has been a problem that it may not be possible to discover something, or the discovery may be delayed.

Therefore, it is an object of the present invention to prevent the entire building from becoming alarmed when patrolling a building along a predetermined route, and to treat abnormality or other detection signals from sensors as alarms under certain conditions. To provide a patrol security method that ensures safety, does not issue an immediate alarm even if a patroller deviates from a predetermined route, and provides a certain degree of freedom in the patrol course, and an alarm device for carrying out the method. It is.

[Means for Solving the Problems] The present invention provides a method for patrolling a plurality of areas in a building along a predetermined route,
In a patrol alarm method that issues an alarm when an abnormality is detected, when a detection signal is generated in an area more than a predetermined distance from a predetermined route during patrolling, or a detection signal is generated in more than a certain number of areas. It is sometimes treated as a warning.

Further, in this method, it is preferable that a warning is also processed when a predetermined tour end operation is not performed within a predetermined time after the start of the tour.

The present invention also provides an alarm device that is switched between an alert state and a non-alert state to monitor the inside of a building, and generates an alarm when an abnormality is detected in the building during the alert state. A patrol confirmation means is installed in each area that outputs an output when a patroller patrolling on the route performs a predetermined operation, and when a detection signal is generated in an area more than a predetermined distance from the predetermined route during the patrol, or It is configured to process as an alarm when a detection signal occurs in a certain number of areas or more.

[Operation] According to the method of the present invention, when a detection signal is generated in an area more than a predetermined distance from the area where the patroller is present while patrolling multiple areas in a building in a predetermined order, When a detection signal occurs in more than one area, it is treated as an alarm.

Further, even when a predetermined tour end operation is not performed within a predetermined time after the start of the tour, it may be processed as an alarm. In this way, when an abnormality or other detection signal is generated from a sensor, it is treated as an alarm under certain conditions, giving patrollers a certain degree of freedom in their actions depending on the actual situation at the time of patrolling, and also allowing them to control buildings. Even if there is an intruder, you will not be left defenseless and safety will be ensured. When the patrol ends, the entire building will return to the alert state again, and even if there is no operation to end the patrol, the entire building will be automatically turned off after a predetermined time (for example, the time required for a normal patrol) has elapsed. By returning the aircraft to alert status, it is possible to deal with unexpected situations that occur during patrolling.

Further, according to the device of the present invention, when an abnormality or other detection signal is generated from the sensor during patrolling, it is processed as an alarm under certain conditions, and the output from the patrolling confirmation means is used to prevent security guards etc. from patrolling each area. You can check each time.

[Example 1 As shown in Fig. 1, multiple areas (numbers 1 to N
) in a predetermined order (for example, from each room on the first floor to each room on the second floor), a switch 4 is installed in each area as a patrol confirmation means that outputs an output when a patroller performs a predetermined operation. These switches 4 are connected to the alarm device 1 shown in FIG. The alarm device 1 includes one or more transmission lines 2
It is connected to the sensor 3 that detects the condition inside the building via the
For example, it has a function to transfer information to a building management device). Sensors 3 are placed on the ceiling, wall entrances, windows, etc. of each area, and usually detect large vacating situations, door opening/closing, locking/unlocking status, etc., as well as detecting locations and times when there are no workers in the building. to detect intruders, etc. into the building.

The alarm device l of the embodiment confirms the patrol operation by a signal when the patrol confirmation switch 4 is operated in each area as described later, and also confirms the patrol operation in an area that is more than a predetermined distance from a predetermined route during the patrol. When the sensor 3 generates a detection signal, when a detection signal is generated in a certain number of areas or more, or when a predetermined patrol end operation is not performed within a predetermined time after starting the patrol, an alarm is issued. Process. A microcomputer is used as a means for performing such operations.

Next, patrol using the alarm device of the example! Explain how to prepare.

First, patrols by security guards are carried out with the entire building in a state of alert, such as during nighttime hours. Then, as shown in FIG. 1, the process starts from the security room 5, sequentially moves through areas 1 to N (for example, N=18), and ends when it returns to the security room 5.

The alarm device 1 installed in the security room 5 operates according to the procedure shown in the flowchart of FIG.

First, it is checked whether or not a tour start operation has been performed. If NO, the next operation is not performed and the state waits for the tour start operation again. The patrol start operation is performed, for example, by the patroller turning on a patrol switch attached to the alarm device 1.

When the above patrol start operation is performed, the value (area number) i of the patrol area counter of the alarm device is set to 1, and alarm output is prohibited. Here, the generation of detection signals from the sensors placed in the building is checked, and if "Yes", it is determined whether the number of detection signals is greater than or equal to a predetermined number m1, and
If o"°, determine whether the distance from area i (1=1 in this case) to the area where the detection signal is generated is 01 or more. As a result, if the distance is n1 or more, cancel the alarm output prohibition. , the detection signal from the sensor is processed as an alarm.

Furthermore, if the number of detection signals is m1 or more, area i (
In this case, the distance from 1=1) to the detection signal generation area is 0.
It is determined whether the number of detection signals of 2 or more is m2 or more.

However, m2≦m and n2≦n1. As a result of the judgment,
If the number of detection signals is m2 or more, the warning output prohibition is canceled and the detection signal from the sensor is processed as a warning.

Here, the distance between each area is determined, for example, as shown in the following table.

On the other hand, if no detection signal is generated from the sensor, if a detection signal is generated but the distance to the area where it is generated is shorter than 01, or if the number of detection signals whose distance to the area where the detection signal is generated is 02 or more is m2 If the number is less (connector ■), it is determined whether a ``travel operation'' has been performed in area i'.

The patrol operation is performed by the patroller turning on the patrol confirmation switch 4 in each area. When this patrol operation is performed, ii+1, that is, the value i (area number) of the patrol area counter, is incremented by one, and the state returns to the state of checking the generation of a detection signal from the sensor. From then on, perform the above operations in each area.

On the other hand, if there is no patrol operation in area I, it is determined whether or not a tour end operation has been performed. The tour end operation is performed by turning off the tour switch that was turned on at the start of the tour, as described above. When this patrol end operation is performed, the alarm output prohibition state is canceled and the operation is ended, and even if there is no patrol end operation by the time T has elapsed, the alarm output prohibition state is canceled and the operation is ended. Become. This is because the fixed time T is the time required to patrol all areas, and if the patroller does not return to the security room 5 and complete the patrol within that time, an alarm will be issued immediately in the event of an abnormality. It is. Therefore, until the predetermined time T has elapsed, the operation of checking the generation of a detection signal from the sensor and sequentially determining whether or not there has been a patrol operation in each area i, and further whether there has been a tour end operation is repeated.

In addition, it is determined whether the patrol operation in each area i has been performed within a certain period of time Ti, and if there is no patrol operation for a certain period of time T.
The warning output prohibition may also be canceled when i has elapsed. This means that a certain time Ti is the time required to move from area i-1 to area i, and within that time the patroller
This is to immediately issue a 7 report in response to the occurrence of an abnormality even if the patrol confirmation switch 4 is not operated.

Although the embodiments have been described above, the present invention is not limited thereto. For example, the specific configuration of the alarm device that implements the above patrol method, the alarm output from the device, etc. are arbitrarily determined depending on the security and other system configurations. Also,
Patrols include not only security, but also sequential cleaning of each area within the building.

Furthermore, it is also possible to install display means such as indicators or displays that operate in response to patrol confirmation operations in each area in the security room or the center that manages the building to indicate when the patrol is underway. be.

[Effects of the Invention] As described above, the method and apparatus of the present invention can be used even during a tour.
When a predetermined condition is met, the detection signal from the sensor is processed as an alarm, so the entire building does not become alarmed, and it can be used in cases such as when an abnormality occurs in a place far away from the patroller. can detect this and issue an alarm, ensuring higher safety than conventional patrols. Moreover, even if a patroller deviates from a predetermined route, an immediate warning is not issued, and the patroller is given a degree of freedom according to the actual situation of the patrol.
