TECHNICAL FIELD OF THE INVENTION
The present invention relates to a security system for buildings, houses, factories, and the like, and more particularly, to a wireless security system capable of appropriately knowing an internal state without entering a building or the like.
[0002]
[Prior art]
When an abnormality occurs in the security area, the security system notifies a controller installed in the security area to the security center via a communication line. When the security center received this abnormality report, the location of the abnormality and the content of the abnormality were reported to the person in charge, and the person in charge rushed to the applicable monitoring target and made an appropriate response.
[0003]
[Problems to be solved by the invention]
The situation inside the security area changes from moment to moment.For example, if there is an intruder such as a thief, the robot moves inside the security area, and although the sensor in the other place than the sensor originally detected is detecting, The coordinator could not know the status of the monitoring target at the time of such coping.
[0004]
Therefore, an object of the present invention is to realize a security system that enables a coping person to appropriately know a situation in a security area detected by a sensor and that can quickly and appropriately deal with an abnormality.
[0005]
[Means for Solving the Problems]
A wireless security system including a plurality of sensors installed in a security area, a controller that receives a detection signal from the sensor, and a portable confirmation device that is carried by a coping person, wherein the controller is configured to receive the detection signal from the sensor. Storage means for storing the detection history of the detection signal, receiving means for receiving a signal from the portable confirmation device , and a mode setting means for setting the security mode during patrol when receiving a patrol signal in the receiving means, Notifying means for notifying the security center when the receiving signal is received by the receiving means, and transmitting means for transmitting the detection history stored in the storing means to the portable confirmation device when receiving the request signal by the receiving means. has the door, the portable checking device includes an operation unit, a cyclic signal transmitter which transmits a cyclic signal to said controller in response to operation of the operation means A request signal transmitting means for transmitting a request signal to said controller in response to operation of the operation means, receiving means for receiving a detection history from the controller, display means for displaying the detection history received by said receiving means And reading the detection history of the storage means of the controller in response to the operation of the operation means of the portable confirmation device , provided that the security mode of the controller is patrol, and displays the detection history on the display means. A wireless security system is provided. Thereby, when the coping person wants to know the information of the sensor installed in the security area, the coping person can know the situation of the security area at this time, and can quickly cope with the abnormality. It is. For example, immediately before entering the inside of the monitoring target, the inside situation can be known from the outside, so that the coping person's judgment and action can be made accurate, and the coping person's safety can be improved. In addition, by reporting the arrival of the coping person from the controller to the security center, the coping status of the coping person can be grasped one by one at the security center. Further, the detection history cannot be read unless the security area is patrol.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall configuration diagram of the security system. The security system connects a plurality of security areas (A, B,... N) such as buildings, houses, factories and the like to a security center 4 via a communication line 3 such as a telephone line. The controller 1 determines whether an abnormality has occurred in the security area by determining whether a detection signal has been received from a sensor 2 that detects an intruder, a fire, a gas leak, or the like installed at an appropriate position in the security area. Monitoring. When the sensor 2 detects an abnormality, the controller 1 notifies the security center 4 via the telephone line 3 of the abnormality. Upon receiving the abnormality notification, the coping person carries the portable confirmation device 5 described later and heads for the security area.
[0009]
FIG. 2 is a block diagram of the controller 1. In the figure, a sensor I / F 11 is a means for receiving a detection signal from a sensor 2 such as an intruder sensor appropriately installed on a monitoring target, which is connected to the sensor 2 by wire, and which receives a wireless signal. There is. Here, only the sensor I / F 11 for wired connection with the sensor 2 is shown, and the case of wireless communication is omitted.
[0010]
The operation unit 12 includes a numeric keypad and a card reader, and is an operation unit operated by a regular user or coping person in the security area. For example, when the security area shifts from the security release state to the security state or vice versa, it is a means for inputting a password and reading data from an ID card.
[0011]
The display unit 13 includes an LED and an LCD, and displays the state of the security area (e.g., during security or cancellation), the presence or absence of an abnormality, and information on maintenance of the device.
[0012]
The storage unit 14 is configured by a ROM and a RAM, and stores various data and programs such as a user identification code, an identification code of the portable identification device 5, a detection history, and a security system program. The detection history is stored for each detection type. For example, the detection history is stored for each type of fire or intrusion without confusing the fire detection information and the intrusion detection information.
[0013]
The notification unit 17 includes a dial relay or the like, and performs an abnormality notification or the like to the telephone number of the security center 4 stored in the storage unit 14 via the telephone line 3.
[0014]
Further, it has a transmitting unit 15 for transmitting a wireless signal to the portable confirmation device 5, a receiving unit 16 for receiving a wireless signal from the portable confirmation device 5, and a control unit 18 including a microcomputer for controlling these. .
[0015]
FIG. 3 is a block diagram of the portable confirmation device 5. The portable confirmation device 5 includes a display unit 51 including an LCD, an LED, and the like for displaying a state of a security area, an operation unit 52 including a patrol button 521 and a confirmation button 522 that are non-lock type SWs, a program, A storage unit 53 including a ROM and a RAM for storing various data, a transmission unit 54 and a reception unit 55 for transmitting and receiving signals to and from the controller 1, and a control unit 56 such as a microcomputer for controlling these units. .
[0016]
Here, the state of the security area, that is, each mode of the controller 1 during security, release, and patrol will be described. The term “during security” refers to a mode in which when the intruder detection sensor 2 detects an abnormality, the security center 4 is notified of the abnormality via the telephone line 3. On the other hand, it is said that the mode in which the security center 4 is not notified even if the intruder detection sensor 2 detects an abnormality is being canceled. In addition, the mode in which the coping person is in the security area is called patrol, and the security center 4 is not notified of the abnormality even if the intruder detection sensor 2 detects at this time. In order to shift from security to cancellation or from cancellation to security, a legitimate user to be monitored inputs an ID to the operation unit 12 and a user identification code stored in the storage unit 14 is entered. It allows you to migrate when they match. That is, the transition to the state during security or cancellation is restricted so that only authorized users to be monitored can perform the transition. If it is assumed that anyone other than a specific person can perform the transition in this way, for example, if an intruder who is familiar with the operation method of the security system, the transition from during security to during cancellation is performed This is because the security system will not work.
[0017]
Next, an operation flow of the controller 1 will be described. FIG. 4 shows an operation when the controller 1 receives a detection signal from the sensor 2.
[0018]
In step S41, the controller 1 monitors whether there is an input of a detection signal from the sensor 2. When receiving a detection signal of the sensor 2 from the sensor I / F 11, it is determined whether or not security is being performed (step S42). If security is being performed, an abnormality occurrence time, an abnormality type, an abnormality occurrence location, etc. are stored in the storage unit 14. Is stored (step S43). Then, the notification unit 17 dials the telephone number of the security center 4 stored in the storage unit 14 in advance, and notifies the security center 4 of the abnormality information such as the time of occurrence of the abnormality and the type of abnormality via the telephone line 3. (Step S44). Further, an abnormality display according to the type of the sensor 2 is performed on the display unit 13. For example, when the sensor 2 for detecting an intruder detects an abnormality, an intrusion abnormality display is displayed.
[0019]
On the other hand, when it is determined in step S42 that security is not being performed, it is determined whether or not patrol is in progress (step S45). If it is during the patrol, the detection information such as the detection time, the type of the sensor 2 and the occurrence location is stored in the storage unit 14 (step S45), and the process returns to step 41. On the other hand, when it is determined that the vehicle is not traveling, that is, when the vehicle is being released, the process returns to step S41 without performing abnormality storage or the like.
[0020]
Note that the storage unit 14 clears the stored abnormal information and the detection information during patrol when the mode shifts from during security or during patrol to release. Therefore, the detection of the sensor 2 during the cancellation is not stored, and all the abnormal information during the guard and the detection information during the patrol are stored.
[0021]
With reference to FIG. 5, a description will be given of a mode transition from during security to during patrol. In the figure, when the controller 1 receives the traveling signal from the portable confirmation device 5 by the receiving unit 16 (step S51), the identification uniquely assigned to each of the portable confirmation devices 5 included in the traveling signal. The code is compared with the identification code stored in the storage unit 14 in advance (step S52). If they match, the transmitting unit 15 wirelessly transmits the permission signal to the portable confirmation device 5 (step S53).
[0022]
Then, a tour signal indicating that the responder has arrived is transmitted from the notification unit 17 to the security center 4 via the telephone line 3 (step S54). Then, a response signal indicating that the traveling signal has been received is received from the security center 4 (step S55), and the traveling mode setting process ends. Although not shown, when a response signal is not received, a cyclic signal transmission operation is performed again. Thus, the security center 4 can confirm that the responder has arrived at the security area and is responding. On the other hand, if the identification codes of the portable confirmation device 5 do not match in step S52, the flow ends.
[0023]
Next, the mode transition of the controller 1 from patrol to guarding will be described with reference to FIG. When the controller 1 receives the under-guard signal from the portable confirmation device 5 at the receiving unit 16 when the patrol is completed (step S61), the controller 1 is individually assigned to the portable confirmation device 5 included in the under-security signal. Then, the identification code is compared with the identification code stored in the storage unit 14 in advance (step S62). If they match, it is determined whether all of the connected sensors 2 are in a normal state (step S63). Here, the condition that all the sensors 2 are in the normal state means that if the sensor 2 remains abnormal, the coping itself has not been completed. This is to prevent
[0024]
If it is determined that the normal state, (step S64) with wirelessly transmits a permission signal to the mobile-type checking device 5 proceeds into security from patrol mode (step S67).
[0025]
On the other hand, if any abnormality remains in the sensor 2, the process proceeds to step S65, in which a non-permission signal is wirelessly transmitted to the portable confirmation device 5, and thereafter, the present flow ends.
[0026]
When a transition is made during security, a security signal is transmitted to the security center 4 via the telephone line 3 (step S67). Then, a response signal to the security signal is received from the security center 4 (step S68), and the mode transition to security is completed. Although not shown, when the response signal is not received, the security signal is transmitted again. Thereby, the security center 4 can confirm that the countermeasures for the monitoring target have been completed.
[0027]
If the identification codes of the portable confirmation device 5 do not match in step S62, the flow ends.
[0028]
The transmission operation of the detection history information of the controller 1 will be described with reference to FIG. For example, when the coping person receives the detection history request signal from the portable confirmation device 5 outside the security area by the receiving unit 16 (step S71), the controller 1 determines whether the patrol is in progress in step S72. Note that the sensor type signal is transmitted from the portable confirmation device 5 together with the detection history request signal. Then, during the patrol, the detection history regarding the sensor 2 of the corresponding sensor type stored in the storage unit 14 is read, and the transmission history is wirelessly transmitted from the transmission unit 15 to the portable confirmation device 5 (step S73). Thereby, the coping person can know the detection status of the sensor 2 in the security area with the portable confirmation device 5, and without entering the security area, for example, the movement of the intruder, the spread state of the fire, and the like. I can judge.
[0029]
With reference to FIG. 8, an operation when the portable confirmation device 5 shifts the controller 1 from during security or cancellation to during patrol will be described. When the user presses the tour button 521 (step S81), the tour unit 54 wirelessly transmits the tour signal to the controller 1 including the own unique identification code stored in the storage unit 53 (step S82). . Thereafter, it is determined whether or not a permission signal has been received from the controller 1 via the receiving unit 55 within a predetermined time (step S83). If the permission signal has been received, the tour OK is displayed on the display unit 51 in step S84. On the other hand, when the permission signal is not received, the traveling NG is displayed on the display unit 51.
[0030]
Thereby, the coping person can confirm that the controller 1 is in patrol and that the security center 4 has been notified that the controller 1 has arrived at the security area.
[0031]
With reference to FIG. 9, an operation in which the portable confirmation device 5 confirms the abnormality history from the controller 1 will be described. First, when the confirmation button 522 is operated (step S91), the transmission unit 54 wirelessly transmits an abnormality history transmission request signal to the controller 1 together with the sensor type signal (step 92). Thereafter, it is determined whether or not the abnormality history signal has been received from the controller 1 via the receiving unit 55 within a predetermined time (step S93). If the abnormality history signal is received, the received abnormality history is displayed on the display unit 51 in step S94. On the other hand, if no abnormality history signal has been received, communication NG is displayed on the display unit 51 (step S95).

[0032]
Next, an operation sequence of the entire security system when an abnormality occurs in a security area during security will be described with reference to FIG.
[0033]
First, when the intrusion sensor 2 in the security area detects an intruder, the controller 1 notifies the security center 4 via the telephone line 3 to the security center 4 based on the operation flow described above with reference to FIG. Upon receiving the abnormality report, the security center 4 transmits a response signal to the effect that the security center 4 has received the notification. Then, the security center 4 sends the responder to the monitoring target that has reported the abnormality. The coordinator who has received the coping instruction carries the portable confirmation device 5 and rushes to the monitoring target where the abnormality has occurred (step S101).
[0034]
Thereafter, when the responder arrives at the monitoring target and presses the patrol button 521 of the portable confirmation device 5, a traveling signal is sent from the portable confirmation device 5 to the controller 1 as described above with reference to FIGS. When wirelessly transmitted, the controller 1 that has received the patrol signal wirelessly transmits a permission signal to the portable confirmation device, and transmits a patrol signal to the security center 4. When the portable confirmation device 5 receives the permission signal, the display unit 51 displays that the state has changed from guarding to patrol (step S102). Thereby, the security center 4 can confirm that the responder has arrived at the monitoring target. In addition, since the patrol signal is wirelessly transmitted from the portable confirmation device 5, it is possible to report to the security center 4 that security is being handled during inspection from outside the security area before entering the security area. The security center 4 can grasp the outside inspection status of the person.
[0035]
Next, when the user presses the confirmation button 522 of the portable confirmation device 5, as described above with reference to FIGS. 8 and 6, the portable confirmation device 5 wirelessly transmits an abnormality history transmission request signal to the controller. Upon transmission, the controller 1 wirelessly transmits the abnormality history information to the portable confirmation device 5. Then, the abnormality history is displayed on the portable confirmation device 5, and when the coping person wants to know, the detection status of the sensor 2 in the security area at that time, that is, the movement status of the intruder can be known. Yes (step S103). This allows the responder to know where in the security area the intruder is likely to be lurking at present without entering the security area.
[0036]
After performing appropriate measures such as confirming the presence or absence of an intruder and initial extinguishing a fire, when the patrol button 521 of the portable confirmation device 5 is pressed again, a guard signal is transmitted to the controller 1. Then, when the controller 1 receives the guarding signal, as described above with reference to FIG. 5, only when all abnormalities have disappeared, the mode is changed from patrol to patrol, and the guarding signal is sent to the guard center. Send to 4. Thus, the security center 4 can confirm that the handling of the abnormality has been successfully completed. Further, a response signal is transmitted to the portable confirmation device 5. Note that the guarding signal may not be transmitted from the portable confirmation device 5 and the operator may operate the operation unit 12 of the controller 1. Further, the detection history stored in the storage unit of the controller 1 is automatically deleted when the mode is changed. Thereby, effective use of the storage unit 14 can be achieved. However, without being limited to this, a first-in first-out type storage unit may be used to store only a predetermined amount of the latest detection history. Further, when the patrol button is pressed at the end of the handling or at the end of the raising inspection, the detection history of the sensor during the patrol may be displayed to confirm the location detected by the handling person.
[0037]
【The invention's effect】
As described above, the operator can know the state of the security area obtained from the sensor by operating the portable confirmation device. Therefore, not only the sensory information but also the sensory information of the coping person can be used, so that a more appropriate and prompt response to the abnormality can be performed. In addition, since the arrival of the coping person at the security center can be immediately known, it is useful for grasping the situation of the coping person, and as a result, the reliability of the security system is improved.
