Description

  The present invention relates to a security system including a security device that monitors an abnormality of a security target, and more particularly, to a security system including an illumination device that lights and illuminates when a human body is detected.

  Conventionally, a security system has been developed for detecting an intruder intrusion into a store or a house and enabling early dispatch of a reporter or coping personnel (see Patent Document 1).

For example, in Patent Document 1, an intruder detection sensor (security sensor) installed in a surveillance building to be guarded is connected to a controller (security device), and the controller communicates when the intruder detection sensor detects an abnormality. A centralized monitoring system for transmitting an abnormal signal to a central monitoring center through a line is disclosed.
In this centralized monitoring system, the central monitoring center includes a central monitoring device that receives abnormal signals from a plurality of controllers. When the central monitoring device receives an abnormal signal, the central monitoring device displays the name of the security target in which the abnormality has occurred. The controller of the central monitoring center constantly monitors the central monitoring device to check whether there is an abnormality in the security target. Then, when the controller confirms that an abnormality has occurred, it instructs the coping personnel in charge of the security of the security target in which the abnormality has occurred to instruct the security target. Then, the coping staff who receives the request for coping starts the coping toward the security target where the abnormality has occurred.

In general, when the response personnel arrive at the security target, before entering the security target facility, inspection starts from the outer periphery of the security target, such as the entrance / exit of the facility, windows, outer walls, etc. Check if there is evidence of intrusion. As a result, coping personnel can detect the presence of an intruder before inspecting the inside of the guarded object, and request the monitoring center controller to report to the police or to support other coping personnel. It becomes possible.
Here, on the outer periphery of the security target, when the human body is detected, it is turned on to provide a guidance illumination for guiding a legitimate user, or a human body detection function for performing a threatening illumination to threaten a suspicious person An attached lighting device, so-called sensor light, may be installed (see, for example, Patent Document 2). In addition, by linking the camera to such illumination, a camera with a human body detection function and an illumination function that turns on the illumination for shooting when a human body is detected and also takes a picture with the camera, so-called sensor light camera is installed. (For example, refer to Patent Document 3).

A security system comprising at least a security device is provided. In such a security system, the security device includes a mode setting unit that manages a plurality of operation modes including a patrol mode that the coping personnel are handling, and a lighting control that prohibits lighting of the lighting device when the operation mode is the patrol mode. It has the part.
With this configuration, the lighting device can be prohibited from being turned on when the security device to be guarded is set to the patrol mode. Can be reduced.
The security target may be an individual building itself or a section of a certain building.

  In addition, the lighting device is installed so as to illuminate the outer periphery based on the human body detection in the outer periphery of the facility to be guarded, and the guard device is a communication unit that receives a transition signal to the traveling mode transmitted wirelessly or by wire. It is preferable to have. With this configuration, when the lighting device is installed on the outer periphery of the facility to be guarded, it is possible to shift to the patrol mode from a remote location. It is possible to prevent an intruder inside the security target facility from being detected. In addition, it is preferable that the transition signal to the traveling mode according to the present invention is transmitted as a radio signal from the center device through a communication line or from a portable terminal possessed by a coping person.

Further, the security device has an operation unit that is operated by the coping personnel to shift the operation mode to the internal inspection mode, and the patrol mode includes an external inspection mode in which the coping personnel inspects the outer periphery of the facility to be guarded, and a security mode. Including the internal inspection mode for inspecting the inside of the target, when the mode setting unit receives a transition signal to the external inspection mode from the communication unit, the mode setting unit shifts to the external inspection mode and sends a transition signal from the operation unit to the internal inspection mode. When received, it is preferable to shift to the internal inspection mode, and it is preferable that the lighting control unit prohibits the lighting device from being turned on only in the external inspection mode.
With such a configuration, lighting of the lighting device is prohibited only when the coping personnel are coping, especially when the coping personnel checks the outer periphery of the security target facility. That is, when the coping personnel inspect the inside of the security target facility, the lighting device is allowed to turn on, so that the intruder escapes outside the security target or the intruder ambushes around the security target facility. Coping personnel can easily detect that

  The storage unit 65 includes a rewritable nonvolatile memory such as a flash memory or an EEPROM and a ROM. The storage unit 65 includes a control program for the security device 6, a mode flag indicating the operation mode of the security device 6, verification information for verification with the identification number acquired from the operation unit 63, the center device 7, or the mobile terminal 10, and abnormality detection An abnormality history representing the history of the image and an image taken by the sensor light camera 5 are stored. As the verification information, for example, a password, an identification number of a registered user or handling person, an identification number of the traveling portable terminal 10, an identification number of the center device 7 or the like is used. These pieces of information are read from the storage unit 65 by the control unit 66 or written into the storage unit 65 by the control unit 66 as necessary.

The control unit 66 includes a CPU, a ROM, a RAM, and the like. The control unit 66 includes control programs and settings for the overall control of the security sensor 3, the sensor light 4, and the sensor light camera 5 connected to each part of the security device 6 and the security device 6. Process according to the selected operation mode. For this purpose, the control unit 66 receives an authentication unit 661 that determines whether or not to permit mode setting based on the mode transition signal and the identification number acquired from the communication unit 62 or the operation unit 63, and the determination result of the authentication unit 661. A mode setting unit 662 that manages a plurality of operation modes of the security device 6, and an illumination control unit 663 that controls lighting of the sensor light 4 and the sensor light camera 5. The authentication unit 661, the mode setting unit 662, and the illumination control unit 663 are implemented as program modules that constitute a part of a control program executed by the control unit 66.
Since other techniques such as memory control, communication control, monitor display control, etc. are performed normally, a detailed description thereof will be omitted.

  The mode setting unit 662 sets the operation mode of the security device 6. Here, three types of operation modes of the security device are prepared: a security set mode, a security release mode, and a patrol mode. The patrol mode includes an external inspection mode and an internal inspection mode.

  In the security set mode, the security device 6 is set in a normal monitoring state. When this mode is set (for example, when the value of the mode flag is set to '0' to indicate the security set mode), the security device 6 is connected to the security sensor 3, the sensor light 4 or the sensor light camera 5. When a detection signal is received from any one of them, the center device 7 is notified as an abnormality detection signal. Furthermore, image information captured by detecting an intruder or the like with the sensor light camera 5 is transmitted to the center device 7.

  The security release mode is a state where the security device 6 does not monitor the security target. When this mode is set (for example, when the value of the mode flag is set to “1” to indicate the security release mode), the security device 6 is connected to the security sensor 3, the sensor light 4, or the sensor light camera 5. Even if a detection signal is received from either one, it is ignored and no notification to the center device 7 is made.

  The patrol mode is a mode indicating that the coping personnel are coping with the security target informed of the occurrence of abnormality by the center device 7. The patrol mode includes an external inspection mode indicating that the handling personnel are dealing with the outer periphery of the guarded facility 2, and an internal inspection mode indicating that the handling personnel are dealing with the inside of the guarded facility 2. There is. When the external inspection mode is set (for example, when the value of the mode flag is set to “2” to indicate the external inspection mode), the security device 6 has the security sensor 3, the sensor light 4, or the sensor light camera 5. When the detection signal is received from any of the above, the abnormality history in the storage unit 65 is updated. When the external inspection mode is set, since the center apparatus 7 is notified that an abnormality has already occurred, the detected abnormality is not notified to the center apparatus 7. In addition, you may make it notify to the center apparatus 7 not as abnormality but as sensor detection information at the time of patrol mode. When the external inspection mode is set, the security device 6 is installed on the outer periphery of the security target facility 2 so that the intruder in the security target facility 2 does not realize the presence of the handling personnel. The lighting of the sensor light 4 and the sensor light camera 5) is prohibited. Further, image information captured by detecting a human body with the sensor light camera 5 is also temporarily stored in the storage unit 65. In addition, unlike the security set mode, all of the lighting prohibition signals are used to control the sensor light 4 or the sensor light camera 5 so that the sensor light 4 or the sensor light camera 5 is not turned on even if the sensor light 4 or the sensor light camera 5 detects a human body. The sensor light 4 and the sensor light camera 5 are transmitted.

The internal inspection mode is a mode used when the coping staff inspects the inside of the security target facility 2 in which the occurrence of abnormality is notified to the center device 7. When this mode is set (for example, when the value of the mode flag is set to “3” to indicate the internal inspection mode), the security device 6 is connected to the security sensor 3 and the sensor light in the same manner as the external inspection mode. When a detection signal is received from either 4 or the sensor light camera 5, the abnormality history in the storage unit 65 is updated. Further, the detected abnormality is not notified to the center device 7. In addition, you may notify the mobile terminal 10 for patrol which the coping staff possesses that the abnormality was detected and the installation location of the detected sensor. Further, image information captured by detecting a human body with the sensor light camera 5 is also temporarily stored in the storage unit 65. However, unlike the external inspection mode, when the human body is detected by either the sensor light 4 or the sensor light camera 5, the detected sensor light 4 or the sensor light camera 5 is controlled to be lit and illuminated. A lighting prohibition release signal is transmitted to all sensor lights 4 and sensor light cameras 5.
In the present embodiment, the patrol mode is distinguished from the external inspection mode and the internal inspection mode, but only the external inspection mode may be set as the patrol mode without making such distinction.

The mode setting operation by the mode setting unit 662 will be described below.
When the mode setting unit 662 acquires the mode transition signal from the operation unit 63 and the authentication unit 661 permits the change of the operation mode by the mode transition signal, the security device 6 is set to the operation mode corresponding to the mode transition signal. To do. When the mode shift signal is received from the center device 7 through the communication line 9 and the authentication unit 661 permits the change of the operation mode by the mode shift signal, the security device 6 is set to the operation mode corresponding to the mode shift signal. To do. Similarly, when the mode transition signal is received by wireless communication from the traveling portable terminal 10 and the change of the operation mode by the authentication unit 661 is permitted, the security device 6 is set to the operation mode corresponding to the mode transition signal.
The mode setting unit 662 updates the value of the mode flag stored in the storage unit 65 to a value representing the operation mode after the change every time the operation mode is changed. Further, the operation mode after the transition is transmitted to the center device 7 through the communication line 9 together with the identification number of the security device 6.

  The authentication unit 661 determines whether or not the operator of the operation unit 63 has a proper operation authority such as a registered user or a coping person. For this purpose, it is checked whether or not the identification number acquired from the operation unit 63 matches that previously registered in the storage unit 65. If they match, the operator is authenticated as having a proper operation authority, and the operation mode of the security device 6 can be shifted by an operation performed through the operation unit 63. If a password is set, it is also checked whether the password acquired from the operation unit 63 matches the password stored in the storage unit 65. Only when the password matches, the operation mode transition is permitted. To do.

  Here, when the card type information of the ID card included in the mode transition signal input from the operation unit 63 represents the circulating card, the authentication unit 661 is in the security set mode, the security release mode, or the internal inspection mode. The transition to one of the operation modes is permitted. However, when the card identification information included in the mode transition signal input from the operation unit 63 represents a user card, only the change to the security set mode or the security release mode is permitted, and the external inspection mode or Transition to internal inspection mode is not permitted.

  In addition, when the security device 6 receives a mode transition signal from the communication device 62 from the center device 7 or the mobile terminal 10 for patrol, the authentication unit 661 stores an identification number representing the transmission source received together with the mode transition signal, It is collated with the identification number of the apparatus that permits the setting change registered in advance in 65. If it matches any of the identification numbers, the authentication unit 661 permits the transition to the operation mode corresponding to the mode transition signal. However, even if the transition signal to the internal inspection mode is received from the communication unit 62, the transition to the internal inspection mode is not permitted.

  The illumination control unit 663 controls the illumination of the sensor light 4 and sensor light camera 5 connected to the security device 6 with respect to each sensor light 4 and sensor light camera 5 as necessary. A control signal is generated and output through the input / output unit 61. Specifically, when the lighting operation signal or the extinguishing operation signal is input from the light switch of the operation unit 63, the illumination control unit 663 performs the following operation on the sensor light 4 or the sensor light camera 5 specified by the light switch. A lighting operation signal or a light-off operation signal is output through the input / output unit 61.

In addition, when the operation mode of the security device 6 is set to the external inspection mode by the mode setting unit 662, the lighting control unit 663 inputs / outputs the input / output unit 61 to all the sensor lights 4 and sensor light cameras 5 connected thereto. The lighting prohibition signal is output through On the other hand, the lighting control unit 663 is connected when the mode setting unit 662 changes the operation mode of the security device 6 from the external inspection mode to another mode, that is, the security set mode, the security release mode, or the internal inspection mode. A lighting prohibition release signal is output through the input / output unit 61 to all the sensor lights 4 and the sensor light camera 5.
In addition, when the sensor light 4 and the sensor light camera 5 are also installed inside the security target facility 2 and are connected to the security device 6, the lighting prohibition signal and the lighting prohibition release signal are provided on the outer periphery of the guard target facility 2. Be sent to what is installed. In this case, the lighting device installed in the storage unit 65 is stored separately from the lighting device installed outside, and the lighting control unit 663 judges the lighting device installed on the outer periphery and turns on the lighting prohibition signal and the lighting device. A prohibition release signal may be transmitted.

Next, the center apparatus 7 installed in the monitoring center 8 that centrally monitors a plurality of monitoring targets via the communication line 9 will be described.
The center device 7 is installed in the monitoring center 8, a communication unit for communicating with each guard device 6 through the communication line 9, a monitor for displaying the status of each guard device 6, and a controller of the center device 7. An operation panel for performing operations and a control unit for controlling the entire center device 7 are configured. Then, when the center device 7 receives the abnormality detection signal from any of the security devices 6, the center device 7 displays that the abnormality has occurred on the monitor and the security device (or the security target) where the abnormality has occurred, and notifies the controller. Further, the center device 7 can transmit a mode transition signal so as to set the operation mode to the external inspection mode to the security device 6 that has received the abnormality detection signal by the operation of the controller through the operation panel. At that time, the identification number of the center device 7 is also transmitted for verification in the security device 6. The center device 7 can also transmit a mode transition signal for changing the operation mode of the security device 6 to the security set mode or the security release mode together with the identification number of the center device 7 by the operation of the controller through the operation panel.
The mode transition signal from the center device 7 is not necessarily required if the traveling portable terminal 10 described later is used. When the controller confirms on the monitor that an abnormality has occurred in the monitoring target, the controller instructs the coping staff to handle the monitoring target.

  The traveling portable terminal 10 is a wireless communication terminal possessed by the coping personnel, and is capable of communication using the same wireless communication protocol as the short-range wireless communication protocol used in the communication unit 62 of the security device 6. In addition, the mobile terminal 10 for patrol is a mode transition signal for setting the operation mode of the security device 6 to the external inspection mode, the security release mode, or the security set mode, and the mobile terminal 10 for patrol by the operation of the handling personnel. You can send your own identification number.

Next, the operation flow of the operation mode transition process of the security device 6 will be described with reference to FIG. The process flow described below is performed by the mode setting unit 662 and the illumination control unit 663 of the control unit 66. This flow is started when a mode transition signal is input to the mode setting unit 662 when the authentication unit 661 permits mode transition.
As shown in FIG. 3, when a mode transition signal is input first, the mode setting unit 662 determines whether or not the mode transition signal is a transition signal to the external inspection mode (step S201). When the mode setting unit 662 is a transition signal to the external inspection mode, the mode setting unit 662 sets the operation mode to the external inspection mode, and rewrites the value of the mode flag stored in the storage unit 65 to a value representing the external inspection mode ( Step S202). Further, the center device 7 is notified that the operation mode has been shifted to the external inspection mode together with the identification number of the security device 6. When a setting operation is performed using the traveling mobile terminal 10, the traveling mobile terminal 10 is also notified that the operation mode has been shifted to the external inspection mode. Thereafter, the illumination control unit 663 outputs a lighting prohibition signal to the sensor light 4 and the sensor light camera 5 through the input / output unit 61 as a lighting control signal (step S203). Thereafter, the migration process ends.

  On the other hand, if the mode transition signal is not a transition signal to the external inspection mode in step S201, the mode setting unit 662 determines whether or not the mode transition signal is a transition signal to the internal inspection mode (step S204). If the signal is a transition signal to the internal inspection mode, the mode setting unit 662 sets the operation mode to the internal inspection mode, and rewrites the value of the mode flag stored in the storage unit 65 to a value representing the internal inspection mode ( Step S205). Further, the center device 7 is notified that the operation mode has been shifted to the internal inspection mode together with the identification number of the security device 6. Thereafter, the lighting control unit 663 determines whether or not the operation mode before the transition is the external inspection mode (step S206), and when the operation mode before the transition is the external inspection mode, the lighting control signal is turned on as a lighting control signal. The release signal is output to the sensor light 4 and the sensor light camera 5 through the input / output unit 61 (step S207). Thereafter, the migration process ends. On the other hand, when the operation mode before the transition is an operation mode other than the external inspection mode, the transition process is terminated without outputting a lighting control signal.

If the mode transition signal is not the transition signal to the internal inspection mode in step S204, the mode setting unit 662 determines whether or not the mode transition signal is a transition signal to the guard set mode (step S208). When the mode transition signal is a transition signal to the guard set mode, the mode setting unit 662 sets the operation mode to the guard set mode, and sets the value of the mode flag stored in the storage unit 65 to a value representing the guard set mode. Rewriting is performed (step S209). Further, the center device 7 is notified that the operation mode has been shifted to the security set mode together with the identification number of the security device 6. On the other hand, when the mode transition signal is not a transition signal to the security set mode, that is, in this embodiment, when the mode transition signal is a transition signal to the security release mode, the mode setting unit 662 sets the operation mode to the security release mode. And the value of the mode flag stored in the storage unit 65 is rewritten to a value representing the security release mode (step S210). Further, the center device 7 is notified that the operation mode has been shifted to the security release mode together with the identification number of the security device 6.
After step S209 or S210, after the process of steps S206 and S207, the migration process ends.

  The sensor light 4 and the sensor light camera 5 are illumination devices including a sensor that detects a human body that has entered the detection range and a light source for illumination, and are installed on the outer periphery of the security target facility 2. The sensor light 4 and the sensor light camera 5 are turned on when a human body is detected within the detection range when the illuminance of the ambient light is not more than a predetermined value, and illuminate the surroundings. Further, when the sensor light camera 5 detects a human body, the sensor light camera 5 acquires image information obtained by capturing a predetermined range, and transmits the acquired image information to the security device 6.

  FIG. 4 is a functional block diagram of the sensor light 4. As shown in FIG. 4, the sensor light 4 includes an illumination unit 41, an illuminance sensor 42, a detection unit 43, a storage unit 44, an input / output unit 45, and a lighting control unit 46.

The illumination unit 41 includes a light source such as a halogen lamp and an incandescent lamp, a power supply circuit that supplies current to the light source, a switch provided in the power supply circuit, and the like. When a lighting instruction is issued from the lighting control unit 46, a switch is connected to light the light source and illuminate a predetermined range.
The illuminance sensor 42 includes a photoelectric conversion element that generates current according to the amount of received light, such as a phototransistor, and an electronic circuit that amplifies the generated current, and measures the illuminance of ambient light around the sensor light 4. Then, the illuminance sensor 42 transmits the measured illuminance of the ambient light to the lighting control unit 46.

  The detection unit 43 includes an infrared light receiving unit 431 and a determination unit 432, and detects the presence or absence of a human body within the detection range. The infrared light receiving unit 431 is a differential detector composed of a pyroelectric element or the like. The infrared light receiving unit 431 detects a change amount of infrared rays generated within the detection range and transmits the change amount to the determination unit 432 as an electric signal. . The determination unit 432 is configured by an electronic circuit or the like, and compares the amount of change in infrared received from the infrared light receiving unit 431 with a predetermined threshold. When the amount of change is larger than a predetermined threshold value, a detection signal indicating that a human body exists within the detection range is transmitted to the lighting control unit 46.

  The storage unit 44 includes a nonvolatile rewritable memory such as a flash memory and a ROM, and stores a control program for controlling the operation of the sensor light 4. In addition, the storage unit 44 stores a lighting prohibition flag indicating whether the sensor light 4 is turned on or off.

  The input / output unit 45 is an interface for communicating with the security device 6, and includes a connection terminal for connecting a communication line with the security device 6, a communication circuit, a control program thereof, and the like. Various control signals such as forcible lighting execution or lighting prohibition are received from the security device 6 according to a predetermined communication protocol defined between On the other hand, the input / output unit 45 transmits a signal representing the state of the sensor light 4 emitted from the lighting control unit 46, a detection signal, and the like to the security device 6. Note that the input / output unit 45 is not limited to a device that communicates with the security device 6 by wire, and may be a device that performs wireless communication.

  The lighting control unit 46 includes an embedded microprocessor and RAM, and operates according to a control program read from the storage unit 44 to control each unit of the sensor light 4. In particular, the lighting control unit 46 controls whether or not the lighting unit 41 is lit based on the illuminance of the ambient light detected by the illuminance sensor 42, the detection signal from the detection unit 43, and the value of the lighting prohibition flag. . Specifically, the lighting control unit 46 determines whether the illuminance of the ambient light is equal to or less than a predetermined threshold value. If the illuminance of the ambient light is equal to or less than a predetermined threshold, the lighting prohibition flag stored in the storage unit 44 is referred to, and the lighting prohibition flag is OFF, that is, a value indicating lighting permission (for example, the value is' When the detection signal indicating that the presence of an intruder within the detection range is detected from the detection unit 43, the illumination unit 41 is turned on. Then, after a certain period (for example, 30 seconds) has elapsed since the detection unit 43 no longer detects the presence of a human body, the illumination unit 41 is turned off. On the other hand, the lighting control unit 46 has the lighting prohibition flag ON, that is, a value indicating that lighting is not permitted, even when the ambient light illuminance is equal to or lower than a predetermined threshold value and a detection signal is received from the detection unit 43. In some cases (for example, when the value is “1”), the illumination unit 41 is not turned on. Further, the lighting control unit 46 does not light the lighting unit 41 when the illuminance of the ambient light is higher than the predetermined threshold or when the detection signal is not received. In addition, when the lighting operation signal for forcibly lighting the lighting is received from the security device 6, the lighting unit 41 is turned on regardless of the above.

Next, the illumination operation of the sensor light 4 will be described with reference to FIG. The process flow described below is controlled by a control program executed on the lighting control unit 46.
First, when the power of the sensor light 4 is turned on and the sensor light 4 starts to operate, the lighting control unit 46 sets the lighting prohibition flag to OFF, that is, a value indicating lighting permission (step S101). Thereafter, the lighting control unit 46 checks whether a lighting control signal is received from the security device 6 (step S102). When the lighting control signal is not received, the control is shifted to before step S110. On the other hand, when a lighting control signal is received in step S102, it is determined whether or not the lighting control signal is a lighting prohibition signal (step S103). When the lighting control signal is a lighting prohibition signal, the lighting control unit 46 rewrites the lighting prohibition flag to a value representing ON, that is, lighting prohibition (step S104). Then, the control proceeds to step S110.

  If the lighting control signal is not a lighting prohibition signal in step S103, the lighting control unit 46 determines whether or not the lighting control signal is a lighting prohibition release signal (step S105). If the lighting control signal is a lighting prohibition release signal, the lighting control unit 46 rewrites the lighting prohibition flag to OFF (step S106). Then, the control proceeds to step S110.

  In step S105, when the lighting control signal is not the lighting prohibition release signal, the lighting control unit 46 determines whether the lighting control signal is a lighting operation signal or a lighting operation signal (step S107). When the lighting control signal is a lighting operation signal, the lighting control unit 46 lights the lighting unit 41 (step S108). Note that the lighting control unit 46 may refer to the value of the lighting prohibition flag, and may not turn on the illumination unit 41 when the lighting prohibition flag is ON. After step S108, the lighting control unit 46 shifts the control to before step S102. On the other hand, when the lighting control signal is a turn-off operation signal, the lighting control unit 46 turns off the illumination unit 41 (step S109). Thereafter, the control shifts before step S102.

Next, in step S <b> 110, the lighting control unit 46 checks whether or not a human body is detected by the detection unit 43. When a human body is not detected, if the illumination unit 41 is on, the illumination unit 41 is turned off after a certain period of time has elapsed (step S111), and control is transferred to step S102. On the other hand, when a human body is detected in step S110, it is determined whether or not the lighting prohibition flag is ON (step S112). If the lighting prohibition flag is ON, the control is shifted to before step S102. On the other hand, when the lighting prohibition flag is OFF, the lighting control unit 46 determines whether or not the illuminance measured by the illuminance sensor 42 is equal to or less than a predetermined value (step S113). And if illumination intensity is below a predetermined value, the lighting control part 46 will light the illumination part 41 (step S114). Thereafter, control is returned to before step S102. On the other hand, if the illuminance is higher than the predetermined value in step S113, the lighting control unit 46 returns the control to before step S102 without lighting the illumination unit 41.
The above processing is repeated until the sensor light 4 is turned off.

As illustrated in FIG. 6, the sensor light camera 5 includes an illumination unit 51, an illuminance sensor 52, a detection unit 53, a storage unit 54, an input / output unit 55, a lighting control unit 56, and an imaging unit 57. Among them, the illumination unit 51, the illuminance sensor 52, and the detection unit 53 have the same functions and configurations as the illumination unit 41, the illuminance sensor 42, and the detection unit 43 of the sensor light 4, respectively. Is omitted.

  The imaging unit 57 includes a detection element that is a two-dimensional array of photoelectric conversion elements such as a CCD and a C-MOS sensor, and an optical system that forms an image of a predetermined area on the detection element. Then, when the imaging unit 57 receives the imaging start signal from the lighting control unit 56, the imaging unit 57 starts imaging. The captured image information is output to the lighting control unit 56 until a shooting end signal is received from the lighting control unit 56. Note that when the detection unit 53 detects a human body, the imaging unit 57 preferably captures a range including the entire detection range of the detection unit 53 in order to record the detection target on the image.

  Similar to the storage unit 44 of the sensor light 4, the storage unit 54 is configured by a non-volatile rewritable memory such as a flash memory and a ROM, and a control program for controlling the operation of the sensor light camera 5 and lighting permission of the sensor light camera 5 Alternatively, a lighting prohibition flag indicating non-permission is stored. Further, the storage unit 54 may temporarily store image information captured by the imaging unit 57.

  Similarly to the input / output unit 45 of the sensor light 4, the input / output unit 55 includes a connection terminal for connecting a communication line with the security device 6, a communication circuit, a control program thereof, and the like. Various control signals such as forcible lighting execution or lighting prohibition are received from the security device 6 in accordance with a predetermined communication protocol defined between them. On the other hand, the input / output unit 55 transmits image information captured by the imaging unit 57 to the security device 6 in addition to a signal indicating the state of the sensor light camera 5 emitted from the lighting control unit 46, a detection signal, and the like.

  Similarly to the lighting control unit 46 of the sensor light 4, the lighting control unit 56 is also configured by an embedded microprocessor and RAM, and operates according to a control program read from the storage unit 54. Control. Further, the lighting control unit 56 controls whether or not the lighting unit 51 is lit based on the illuminance of the ambient light detected by the illuminance sensor 52, the detection signal from the detection unit 53, and the value of the lighting prohibition flag. .

Further, when the lighting control unit 56 receives a detection signal indicating that the presence of a human body within the detection range is detected from the detection unit 53, the lighting control unit 56 transmits a shooting start signal to the imaging unit 57 to start shooting. After that, when a certain period of time has elapsed since the detection signal is no longer received from the detection unit 53, the lighting control unit 56 transmits a shooting end signal to the imaging unit 57 to end the shooting. Meanwhile, the lighting control unit 56 receives the image information from the imaging unit 57 and stores it in the storage unit 54. Alternatively, the image information is transmitted to the security device 6 through the input / output unit 55.
Note that the illumination operation of the sensor light camera 5 and the control by the lighting control unit 56 for performing the illumination operation are the same as the illumination operation of the sensor light 4 and the control of the lighting control unit 46 described above. Omitted.

  As described above, in the security system to which the present invention is applied, the sensor light and the sensor light camera can be controlled so that the countermeasure light is not turned on even when the security personnel is detected while the security personnel are handling the security target. Therefore, it is possible to reduce the risk that the behavior of the coping personnel will be perceived by an intruder who is in the guard.

The preferred embodiments of the present invention have been described above, but the present invention is not limited to these embodiments. In the present embodiment, the configuration has been described in which the inspection mode has the external inspection mode and the internal inspection mode as the patrol mode, and the lighting device is prohibited to be lit only in the external inspection mode, but is not limited thereto. .
For example, without distinguishing between the external inspection mode and the internal inspection mode, a traveling mode transition signal is transmitted from the center device 7 or the traveling portable terminal 10 to the security device 6 or input from the operation unit 63 to the control unit 66. The lighting device may be prohibited from lighting when the mode shift is permitted by the authentication unit 661.
In this case, the operation flow shown in FIG. 3 of the security device 6 is changed as follows. That is, step S201 is to determine whether or not the mode setting unit 662 is a signal for shifting to the cyclic mode, and step S202 is to set the cyclic mode and notify the center device 7 to that effect. . Then, Steps S204 and S205 are deleted, and when it is determined in Step S201 that the signal is not a transition signal to the cyclic mode (Step S201: No), the process proceeds to Step S208.

  In addition, for example, the sensor light or the sensor light camera inquires and stores the operation mode from the security device 6 instead of referring to the lighting prohibition flag in order to determine whether lighting is permitted or prohibited. If it is determined that the operation mode is the external inspection mode (patrol mode) when the human body is detected, the lighting is controlled to be prohibited, and the operation mode is the external inspection mode (patrol mode). If it is determined that it is other than the above, it may be controlled to permit lighting.

In addition, the security device 6 may use biometric information in order to perform operator verification. In this case, the security device 6 is provided with a biometrics acquisition device that acquires biometric information such as fingerprints, palm prints, retinas, voices, face images, and the authentication unit stores the acquired biometrics information and the storage unit in advance. The registered biometric information of the registered user (including coping personnel) is checked. If the authentication unit determines that the acquired biometric information matches any registered biometric information, the authentication unit authenticates the operator as a registered user corresponding to the registered biometric information. Since various known algorithms can be used as the biometric information acquisition apparatus and the biometric information collation, detailed description thereof is omitted here.
Furthermore, the coping staff may not belong to the security company and may be a user of the security target facility 2. In this case, the user inputs identification information and operates to request a mode shift using a mobile phone as the mobile terminal 10 for patrol, and the mobile phone sends a mode setting signal to the security device 6 via the communication line. Will be sent.

  Furthermore, in the above embodiment, both the sensor light 4 and the sensor light camera 5 are used. However, the security system according to the present invention may use only the sensor light 4 or the sensor light camera 5. . Further, the sensor light camera 5 may further include an infrared camera that takes a picture when a human body is detected within the detection range when lighting is prohibited (that is, when the lighting prohibition flag is ON). By having such an infrared camera, it is possible to record image information of a human body that has entered the detection range even if the illumination is not turned on.

  As described above, various modifications can be made within the scope of the present invention according to the embodiment to be implemented.
