Description

The present invention is a guard including a control device that controls the operation and stop of an abnormality detection unit that can detect an abnormality inside a room, and a plurality of authentication portable terminals that wirelessly communicate with the control device and that instructs the operation and stop. The present invention relates to the control device and the security system in a system.

For example, in a security system that is installed in a house such as a house and detects illegal intruders indoors, when a resident goes out, set a warning mode to warn the illegal intruder and when the resident returns home. To cancel the warning mode and switch to the normal mode. In a system that authenticates a mobile terminal for authentication when a user performs a switching operation between a warning mode and a normal mode, a control device of the system authenticates the terminal by performing wireless communication.

JP, 2016-200975, A

The range in which the authentication portable terminal and the control device can wirelessly communicate is generally set to about several meters to several tens of meters. Therefore, immediately after the resident has gone out, it may be possible to authenticate the authentication portable terminal carried by the resident. In a general security system, it is necessary to secure enough time for a family member to properly operate the security mode, so even if an intrusion of a person is detected, it will not be reported for a predetermined period. There is. Therefore, there is a possibility that a person who intends to invade the house at that time can perform the operation of canceling the warning mode. If the transmission power of the authentication mobile terminal is weakened in order to eliminate this possibility, for example, depending on the state in which the resident carries the authentication mobile terminal, mode switching will not be performed as expected, and the operability of the system will be reduced. May decrease.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a control device and a security system for a security system capable of reliably eliminating an unauthorized operation by an intruder without degrading operability. is there.

According to the control device of the security system, the control unit controls the operation and stop of the abnormality detection unit based on the operation of the operation unit and the authentication result of the authentication unit. Then, the control unit, within a certain time from the time when the abnormality detection unit is operated, when the operation for canceling the warning mode is performed, the reception intensity measured by the measurement unit exceeds a predetermined threshold value. The operation of the anomaly detector is stopped under the condition that it is present.

For example, right after a family member who is a legitimate operator goes out after setting the alert mode, the control device is ready to receive the radio signal of the authentication portable terminal carried by the operator, and it is illegal during that time. It is assumed that a different operator invades a house and performs an operation to cancel the warning mode. Since the authentication terminal is carried by the person who operates the operation unit, the authentication terminal is in the vicinity of the control device if the authorized operator is performing the operation for canceling. Therefore, the reception intensity of the radio signal becomes high and does not fall below the predetermined threshold.

Then, even if an operation to cancel the warning mode is performed by a person who has invaded the house within a certain period of time, if the distance between the house carrying the authentication portable terminal and the house is a certain distance, the measurement unit measures The received strength is relatively low. Therefore, if the control unit sets the standard of the signal strength required at the time of authentication to be stricter than usual, if the measured reception strength exceeds a predetermined threshold value, the operability is deteriorated. It is possible to prevent an unauthorized operator from canceling the warning mode within a certain period of time. In the following, operating the abnormality detection unit may be referred to as “setting the alert mode”, and stopping the operation may be referred to as “releasing the alert mode”.

According to the control device of the security system, the control unit, at least for the authentication portable terminal possessed by the person who performs the setting operation when operating the abnormality detection unit, the reception intensity measured by the measurement unit is predetermined. The operation of the abnormality detection unit is stopped on the condition that the threshold value is exceeded. Normally, since the authentication portable terminal possessed by the person who has performed the operation of setting the warning mode is present near the control device, the terminal is authenticated by the control device. Therefore, for the authenticated mobile terminal for authentication, if the operation of the abnormality detection unit is stopped under the condition that the reception strength exceeds a predetermined threshold, an unauthorized operator can cancel the warning mode within a certain period of time. Can be eliminated.

According to the control device of the security system, the control unit, when there are a plurality of authentication mobile terminals that have received the radio signal when the abnormality detection unit is activated, performs measurement on the plurality of authentication mobile terminals. The operation of the abnormality detection unit is stopped on the condition that the reception intensity measured by the unit exceeds a predetermined threshold value. For example, when a plurality of family members try to go out with their own portable terminals for authentication, in addition to the terminal authenticated by the control device, there are family members who possess other terminals around the control device. It is also assumed.

Therefore, if there are multiple authentication mobile terminals that have received a radio signal, if the operation of the abnormality detection unit is stopped on the condition that the reception strength exceeds a predetermined threshold for all of those terminals, It is possible to surely prevent an unauthorized operator from canceling the warning mode.

According to the control device of the security system, the control unit has the maximum reception intensity measured by the measurement unit when there are a plurality of authentication portable terminals that have received the radio signal when the abnormality detection unit is activated. Regarding the existing authentication portable terminal, the operation of the abnormality detection unit is stopped on the condition that the reception intensity exceeds a predetermined threshold value.

When multiple householders try to go out with their own portable terminals for authentication, the terminal authenticated by the control device and the terminal possessed by the householder who performed the operation to set the alert mode are different. Is also envisioned. In this case, after the control device authenticates the mobile terminal for authentication, the family member carrying a different terminal is located closer to the control device.

In this state, when the control device performs wireless communication in order to grasp the authentication portable terminals existing in the vicinity, the reception strength of the radio signal of the terminal possessed by the family member who performed the operation to set the warning mode is the highest. Get higher Therefore, for the terminal, if the operation of the abnormality detection unit is stopped on condition that the reception intensity exceeds a predetermined threshold value, the authentication portable terminal that is located near the control device at the end is used to obtain a constant value. It is possible to prevent an unauthorized operator from canceling the warning mode in time.

According to the control device of the security system, the authentication unit authenticates the mobile terminal for authentication even when the operation of setting the warning mode is performed, and the control unit determines that the mobile terminal for authentication is authenticated. The abnormality detection unit is activated. With this configuration, it is possible to prevent the warning mode from being set by a person who has an authentication portable terminal that is not authenticated.

According to the control device of the security system, the control unit controls the operation and stop of the abnormality detection unit based on the operation of the operation unit and the authentication result of the authentication unit. Then, the control unit performs the operation of canceling the warning mode within a certain time from the time when the abnormality detection unit is operated, and the result of the authentication by the authentication unit is the terminal that is authenticated when the abnormality detection unit is operated. If there is, the operation of the abnormality detection unit is stopped on condition that the reception intensity measured by the measurement unit exceeds a predetermined threshold value.

For example, right after a family member who is a legitimate operator goes out after setting the alert mode, the control device is ready to receive the radio signal of the authentication portable terminal carried by the operator, and it is illegal during that time. It is assumed that a different operator invades a house and performs an operation to cancel the warning mode. Since the authentication terminal is carried by the person who operates the operation unit, the authentication terminal is in the vicinity of the control device if the authorized operator is performing the operation for canceling. Therefore, the reception intensity of the radio signal becomes high and does not fall below the predetermined threshold.

Then, at this time, even if the result of the authentication is the terminal authenticated when the abnormality detection unit is activated, the control unit may allow the housekeeper carrying the authentication portable terminal and the house to be separated to some extent. For example, the reception strength measured by the measuring unit becomes a relatively low level. Therefore, under the condition that the measured reception intensity exceeds the predetermined threshold value, the control unit can exclude an unauthorized operator from canceling the warning mode without lowering the operability.

According to the control device of the security system, the control unit does not recognize the existence of the authentication result in the authentication unit when the abnormality detection unit is activated, as well as the operation of canceling the alarm mode within the fixed time period is performed. If it is a portable terminal for authentication, the operation of the abnormality detection unit is stopped without applying the above conditions.

For example, suppose that after the family member B goes out, the family member A sets the warning mode and goes out. Then, when the control device applies the above condition when the family member B returns home within a certain period of time and performs an operation of canceling the warning mode, the family member B cannot cancel. Therefore, the control unit did not recognize the existence when setting the alert mode, that is, when authenticating the terminal that was not authenticated, by stopping the operation of the abnormality detection unit without applying the condition, The resident B can also cancel the warning mode without any problem.

According to the security system, when the control unit of the control device activates the abnormality detection unit, the control unit transmits an instruction to reduce the transmission output of the radio signal used for wireless communication to the authentication mobile terminal, and receives the instruction. The mobile terminal for authentication reduces the transmission output for a certain period of time.

Similar to the above example, when a family member who is a legitimate operator goes out after setting the alert mode, the family member, who is in a state in which communication with the control device is possible at that time, is carried by the family member. The authentication portable terminal including the above reduces the transmission output of the radio signal in response to the instruction from the control device. Therefore, even if an unauthorized operator invades the house and cancels the warning mode immediately after the family member goes out, the operation of the abnormality detection unit is not stopped and cannot be canceled. As a result, similarly, it is possible to prevent an unauthorized operator from canceling the warning mode without deteriorating the operability. Here, "reducing the transmission output" includes stopping the transmission of the radio signal itself.

According to the security system, when the authentication mobile terminal determines that the abnormality detection unit has been activated as a result of being authenticated by the control device based on the confirmation signal received from the control device, the transmission output is reduced for a certain period of time. Let In this case as well, similar to the ninth aspect, it is possible to exclude an unauthorized operator from canceling the warning mode.

According to the security system, the authentication portable terminal is configured such that the operator can cancel the state in which the transmission output is reduced within a fixed time. With this configuration, when a family member who has tried to go out after setting the alert mode returns to the house, for example, when he or she notices something left behind and performs an operation to cancel the alert mode, the radio signal is transmitted by himself/herself. The alarm mode can be released by returning the output to the original level and enabling wireless communication with the control device.

(First embodiment)
Hereinafter, the first embodiment will be described with reference to FIGS. 1 to 4. FIG. 1 is a functional block diagram showing the configuration of the security system of this embodiment. The security system 1 includes a controller 2 and a tag 3 which is a mobile terminal for authentication. The security system 1 is a so-called home security system that detects an abnormality inside a house such as a residence and takes measures such as notification. The security system 1 is not limited to a house such as a residence, but may be installed in a business office or a warehouse. The controller 2 corresponds to a control device and controls the operation and stop of the abnormality detection unit 4.

The abnormality detection unit 4 detects an illegal invasion of an indoor by an intruder as an abnormality. The controller 2 switches the operation and stop of the abnormality detection unit 4, that is, the operation and stop of the security system 1. In addition, as the abnormality detection unit 4, a window opening/closing sensor for detecting opening/closing of the window, a window breaking sensor for detecting breaking of the window due to vibration of the window, a fire sensor for detecting fire, and a gas leak sensor for detecting gas leakage. May be included.

The controller 2 includes a control unit 11, an operation unit 12, and a communication unit 13. The control unit 11 is composed of, for example, a microcomputer, and includes therein various functional units such as a clock 14, a radio wave intensity measuring unit 15, an authentication unit 16 and a storage unit 17. The controller 2 is driven by a battery when it is installed in a place without a power supply or a place where wiring of the power supply is difficult. The operation unit 12 is a switch or the like for being operated by the user and inputting instructions for setting and canceling the warning mode. The communication unit 13 is an interface for the control unit 11 to perform wireless communication with the tag 3, and in the present embodiment, for example, Bluetooth (registered trademark) is used as a communication protocol.

The clock 14 is used to measure the time when a family member goes out and the elapsed time from that time. The radio wave intensity measurement unit 15 is a functional unit that measures the intensity of the radio wave signal received from the tag 3 when performing the above-described wireless communication. The authentication unit 16 is a functional unit that authenticates the ID of the tag 3 included in the radio signal as information. The time of going out and the like are stored in the storage unit 17.

The tag 3 has a size that can be carried by a person, and includes a communication unit 18 and a control unit 19. The communication unit 18 is a communication interface similar to the communication unit 13. The control unit 19 is also composed of a microcomputer and performs various controls as a communication terminal. The tag 3 may be a mobile terminal such as a smartphone.

Next, the operation of this embodiment will be described with reference to FIGS. In these figures, “state: at home” corresponds to a state in which the abnormality detection unit 4 is deactivated and the security mode of the security system 1 is released, and “state: out” indicates that the abnormality detection unit 4 is This corresponds to the state in which the security system 1 is activated and the security mode is set. In the case shown in FIG. 2, the household A carries the tag 3(A), and returns home within 30 minutes after a crime prevention operation, that is, an operation of setting the alert mode, and releases the alert mode. This is the case when an operation is performed.

When the resident A inputs (2) the crime prevention operation, that is, the operation of setting the alert mode by the operation unit 12 from (1) “state: at home”, the controller 2 (3) authenticates with the tag 3 (A). Communicate. When the ID of the tag 3(A) is authenticated, the warning mode is set and (4) the state is changed to "go out", and the ID of the tag 3(A) is set as the ID of the tag 3 possessed by the operator. Record. Immediately after that, the reception of the radio wave signal transmitted from the tag 3 is further tried, and based on the presence or absence of the radio wave signal having an ID other than the tag 3 (A) and the ID, (5) the tag 3 (A) Also check whether or not tags 3 other than the above exist.

(6) When the home operator A, who is the set operator, returns home within 30 minutes and performs an operation to cancel the warning mode, the controller 2 performs authentication with the tag 3 (A) in (7) as in (3). Communicate. When the ID of the tag 3(A) is authenticated, the strength of the radio wave signal received by the radio wave strength measuring unit 15 is measured. If the strength exceeds a predetermined threshold value (8) "reception level is high", (9) "state: at home" is switched to. On the other hand, if the reception intensity is less than or equal to the predetermined threshold (10) and it is determined that "reception level is low", (11) nothing is done and the "state: going out" is maintained. One of the processes (8) and (9) and the processes (10) and (11) is selectively executed.

As a result, when a suspicious person who does not have the tag 3 enters and performs the release operation using the operation unit 13 immediately after switching to the “state: going out” in (4), the controller 2 causes the tag 3 (A). Even in a state where the radio wave signal can be received, if the reception strength is determined at that time, the state is “out” as the “reception level is low” in (10).

FIG. 3 shows a case where the householder A carrying the tag 3(A) returns home after 30 minutes have passed from the crime prevention operation, and then performs the operation of canceling the warning mode. The items (1) to (5) are the same as those shown in FIG. 2, and the releasing operation of the item (6) is performed after 30 minutes have elapsed from the item (2). In this case, unlike the case of FIG. 2, the determination of the reception strength as in (8) to (10) is not performed, and only the result of the authentication communication in (7) is switched to (8) “state: home”. ..

In addition, in FIG. 4, as in FIG. 2, within 30 minutes after the housekeeper A performed the crime prevention operation, the housekeeper B carrying the tag 3 (B) returned home and performed the operation to cancel the warning mode. This is the case. The items (1) to (6) are the same as those in FIG. 2, and the controller 2 authenticates the ID of the tag 3 (B) through the authentication communication of (7). The tag 3(B), unlike the tag 3(A) that was authenticated when the crime prevention operation of (2) was performed, could not be authenticated at that time, that is, the tag 3 that did not exist around the controller 2 Is. Also in this case, similarly to FIG. 3, only the result of the authentication communication of (7) is switched to (8) “state: home”. Therefore, the family member B can also cancel the warning mode without any problem.

As described above, according to the present embodiment, the control unit 11 of the controller 2 controls the operation and stop of the abnormality detection unit 4 based on the operation of the operation unit 12 and the authentication result of the authentication unit 16. Then, the control unit 11 performs authentication when the operation to release the alert mode is performed within 30 minutes, which is a fixed time from the time when the operator sets the alert mode, and when the result of the authentication by the authentication unit 16 is activated. If it is the tag 3 that has been released, the warning mode is released on the condition that the reception intensity measured by the radio field intensity measuring unit 15 exceeds a predetermined threshold value.

As a result, for example, immediately after the householder A goes out after setting the warning mode, the controller 2 is ready to receive the radio signal of the tag 3(A) being carried, and a suspicious person intrudes into the house during that time. Even if the operation for canceling the warning mode is performed, the distance between the house A carrying the tag 3(A) and the house is apart to some extent, and thus the measured reception intensity becomes a relatively low level. .. Therefore, the control unit 11 imposes the above conditions that are stricter than those at the time of authentication associated with the normal release mode operation, and thus it is possible to exclude a suspicious person from releasing the alert mode without lowering the operability. Imposing the above condition on the tag 3 of the set operator is equivalent to limiting the authentication of the tag 3.

In addition, when the cancellation operator is a user other than the set operator within 30 minutes, that is, the control unit 11 performs the operation of canceling the warning mode, and the result of the authentication by the authentication unit 16 sets the warning mode. If the tag 3(B) is different from the authenticated 3(A) at the time, the warning mode is released without applying the above condition. Thereby, the occupant B can cancel the warning mode without lowering the operability even within 30 minutes.

(Second embodiment)
Hereinafter, the same parts as those in the first embodiment will be designated by the same reference numerals, the description thereof will be omitted, and different parts will be described. In the second embodiment, as shown in FIGS. 5 to 7, even if the warning mode is set by the tag 3(A), if it is within 30 minutes from that point, a user other than the set operator possesses it. All tags 3 including the tag 3 are subject to the authentication restriction, and the reception mode is released when any of the tags 3 has a reception intensity equal to or higher than a threshold value and the reception level is high. According to this embodiment, not only the tag 3 (A) possessed by the householder A who is a set operator but also the householder B who is in the vicinity and the outing regardless of whether the tag 3 (A) is communicable during the set operation or not. The tags B and C possessed by the house owner C are also subject to the authentication restriction. In this case as well, similar to the first embodiment, it is possible to exclude a suspicious person from canceling the warning mode immediately after the housekeeper A sets and outputs the warning mode.

(Third Embodiment)
In the third embodiment, as shown in FIGS. 8 and 9, in the configuration in which the tag 3 authentication at the time of the set operation is unnecessary, only the tag 3 possessed by the set operator is subjected to the authentication restriction at the time of the release operation. .. When the householder A carrying the tag 3 (A) performs an operation to set the warning mode, (5) the tag having the highest radio field intensity among the tags 3 that have received the radio signal when checking the surrounding tags 3 is set as the tag 3 possessed by the set operator and is subject to the authentication restriction. In FIG. 8, when the surrounding tags are checked in (5), the reception intensity of the radio wave signal is highest in the tag 3(A), and the radio wave signal emitted by the tag 3(C) is not received. Incidentally, the “connection tag” in the figure means the tag 3 existing in the range in which the controller 2 can communicate.

Then, as shown in FIG. 10, when the tag (3) is authenticated in (7) when the (6) release operation is performed, the reception intensity is equal to or higher than the threshold value, and the “reception level” is set. When it is determined to be "high", the alert mode is canceled. Other tags 3 (B) and 3 (C) can be released without imposing a condition that the reception intensity is equal to or higher than the threshold value.

In this embodiment, the tag 3 may be required to be authenticated during the setting operation. In this case, the authentication of the tag 3 is always tried while the warning mode is canceled, and (2) when the security operation is performed, the warning mode is set when the authentication is performed within a predetermined time immediately before, for example, 3 seconds. set.

(Fourth Embodiment)
In the fourth embodiment, as shown in FIGS. 11 and 12, when the housekeeper A carrying the tag 3(A) performs an operation to set the warning mode and then confirms the surrounding tags in (5). In addition, it is assumed that the tag 3(B) is recognized by the controller 2 in addition to the tag 3(A). In this case, the tag 3(A) and the tag 3(B) are targets of the authentication restriction. When the controller 2 is the tag 3(A) or 3(B) that is authenticated in (7) when the (6) release operation is performed, the reception intensity of these is greater than or equal to the threshold value. When it is determined that the reception level is high, the warning mode is canceled. Other tags 3 (C) can be released without imposing a condition that the reception intensity is equal to or higher than the threshold value. Also in this case, the same effect as the third embodiment can be obtained.

(Fifth Embodiment)
In the fifth embodiment, as shown in FIG. 14, after the householder A carrying the tag 3(A) carries out an operation to set the warning mode as in the fourth embodiment, the controller 2 sets the peripheral area at (5). When confirming the tag, a command for reducing the transmission output of the radio signal is transmitted to the tag 3. Then, the tags 3(A) and 3(B) that have received the command reduce the transmission output for a fixed time, for example, 30 minutes. After a certain period of time, the tags 3(A) and 3(B) restore the transmission output to the original level.

As a result, as shown in FIG. 15, the housekeepers A and B carrying the tags 3(A) and 3(B) approach the controller 2 within the above-described fixed time, and the reception intensity on the controller 2 side is increased. When the threshold value is exceeded, the warning mode can be canceled. Note that the tags 3(A) and 3(B) that receive the command may stop the transmission output for a certain period of time by transmitting a command that stops the transmission output instead of the command that decreases the transmission output. ..

In this way, by reducing the transmission output on the side of the tags 3(A) and 3(B), the same condition as the condition that the strength of the radio signal received by the controller 2 is equal to or more than the threshold value as in the first embodiment, for example. It becomes a state. In other words, the housekeepers A and B who carry the tags 3(A) and 3(B) are in a state where they cannot cancel the warning mode unless they are close to the controller 2 within a certain period of time.

In this case, the tag 3 is configured so that the transmission level can be restored by the operation of the person who owns the tag 3 within a certain period of time during which the transmission level is lowered. For example, as shown in FIG. 16, the tag 3 is provided with a button B for restoring the transmission level, and when the button B is pressed, the transmission level is restored. Further, as shown in FIG. 17, an acceleration sensor is provided inside the tag 3, and the tag 3 is displaced so as to apply a certain acceleration or more in a predetermined direction to the tag 3 to restore the transmission level. And so on.

As a result, when the housekeeper who tries to go out after setting the alert mode returns to the house, for example, when he/she notices something left behind, and performs an operation to cancel the alert mode, the transmission output of the tag 3 is changed to the original one by his/her own operation. The alarm mode can be canceled by returning to the level and enabling wireless communication with the controller 2. Note that in this embodiment, the authentication restriction process performed by the controller 2 in the first to fourth embodiments is unnecessary.

(Sixth Embodiment)
In the sixth embodiment, as shown in FIG. 18, after the housekeeper A carrying the tag 3(A) carries out an operation to set the warning mode as in the fifth embodiment, the controller 2 sets the tag in (3). When the communication for authenticating 3(A) is performed, the tag 3(A) recognizes that the alert mode is set by the authentication signal transmitted from the controller 2 and the like. To do. The acknowledge signal corresponds to a confirmation signal. Then, (6) the tag 3 (A) spontaneously reduces the transmission output of the radio wave signal for a certain period of time. After that, as in the fifth embodiment, the tag 3(A) restores the transmission output to the original level after a certain period of time. Also in this case, the same effect as that of the fifth embodiment can be obtained. The confirmation signal may not be directly transmitted from the controller 2 but may be transmitted to the tag 3(A) via a server or the like.

The present invention is not limited to the embodiments described above or illustrated in the drawings, and the following modifications or expansions are possible.
In the second and fourth to sixth embodiments, the authentication of the tag 3 when setting the alert mode may be performed as necessary. For example, in the second embodiment, the authentication when the operation to set the alarm mode is not performed, the alarm mode is set, and the authentication communication is performed only when the alarm mode is released, and all the tags 3 are authenticated as described above. It may be subject to the restriction. In addition, in the fourth embodiment, when the operation to set the warning mode is performed, the tags 3 existing around are checked, and if the operation to cancel the warning mode is performed within 30 minutes from the setting, the setting operation is performed. The above condition may be imposed only on the tags 3 existing in the vicinity.

The fixed time in each embodiment is not limited to 30 minutes and may be changed as appropriate.
In each embodiment, the authentication communication is not limited to after the crime prevention operation, and may be changed appropriately. For example, it may be performed before the crime prevention operation.
In the fifth embodiment, the configuration in which the transmission level of the tag 3 can be restored may be adopted as needed. Moreover, you may apply the said structure to 6th Embodiment.
In each embodiment, the authentication communication is authenticated if wireless communication is possible, but the authentication communication is not limited to this. For example, the authentication may be performed when the reception intensity of the radio signal from the tag 3 is equal to or higher than a first threshold value set in advance. In this case, the tag 3 that is the subject of the authentication restriction is determined using the second threshold value set higher than the first threshold value.

In the drawings, 1 is a security system, 2 is a controller, 3 is a tag, 4 is an abnormality detection unit, 12 is an operation unit, 15 is a radio field intensity measurement unit, and 16 is an authentication unit.
