Description

  The present invention relates to a wireless security system in which a security terminal having a sensor unit, a wireless transmission / reception unit, and the like and a controller are connected wirelessly.

  In general, a security terminal in a radio security system often operates with a primary battery, and at this time, a problem in operation is the life of the battery. Since the frequency of battery replacement increases as the battery life is shortened, various methods for extending the battery life have been adopted. On the other hand, in the wireless security system, there is a concept of warning / canceling, where “warning” is when the system is set to a warning state, and “canceling” is when the system is set to a released state. At the time of release, there is a high possibility that the security terminal will detect and operate a person in a state where there is a person in the alert area.In addition, at the time of alert, the guard area will be unattended and there will be no movement. For example, the security terminal basically does not perform detection operation, and when a person is detected at the time of the warning, this can be determined as an intruder.

  Conventionally, for example, Patent Documents 1 to 3 have been disclosed as this type of wireless security system. The security system disclosed in Patent Document 1 turns off the power supply to the security terminal (input device) when the system is released, and always performs reception by the security terminal to perform the alarm / release of the controller (control device) in real time. Is receiving. In addition, in the security system (wireless security device) disclosed in Patent Document 2, the security terminal (wireless sensor) includes a sensor unit, a transmission / reception circuit, and two switches. As long as reception is always performed. Furthermore, the security system (wireless sensor system) disclosed in Patent Document 3 turns off the power supply of the transmission unit when the system is released, and the security terminal (sensor unit) is always in an operating state and is set to a controller (controller unit) at regular intervals. ) And receive in sync.

  However, in the security system disclosed in Patent Document 1, although it is possible to prevent malfunction detection information transmission failure due to radio wave interference when a plurality of security terminals transmit simultaneously, the security terminal outputs an abnormal signal. If a response is not received within a certain time after transmission, an abnormal signal is retransmitted to the controller. When this retransmission is repeated, the current consumption of the security terminal increases and the battery life of the security terminal tends to be shortened. .

  In addition, in the security system described in Patent Document 2, since the power of the security terminal is turned on only when transmission with the controller is necessary, the power consumption of the security terminal battery can be reduced to some extent, Sometimes the power is always supplied to the transmission / reception circuit so that reception is possible, so that the battery of the security terminal is consumed at the time of release, and it is difficult to sufficiently extend the battery life.

  Furthermore, in the security system disclosed in Patent Document 3, when the security terminal is switched to the cancellation, the CPU of the terminal cancels the detection signal of the detection unit and stops the unnecessary transmission operation at the time of cancellation. However, it is possible to eliminate wasteful power consumption at the time of release, but the detection unit will not function at the time of release, so the controller cannot determine whether the operation of the sensor unit is normal or not, and the controller performs warning and release operations.

The best mode for carrying out the present invention will be described below in detail with reference to the drawings.
As shown in the block diagram of FIG. 1, a wireless security system 1 according to the present invention includes a security terminal 2 and a controller 3, which are connected wirelessly. The security terminal 2 is installed, for example, in an office such as a factory, a store such as various stores, or an entrance / exit of a security target facility such as a general home, and includes a terminal control unit 4 including a CPU 4a and a storage unit 4b. Have.

  On the input side of the terminal control unit 4, a sensor unit 5 including various sensors such as a heat ray sensor and a door sensor (magnet sensor) and a switch unit 6 including a user switch 6 a described later are connected. On the output side, a display unit 7 composed of an LED, a buzzer or the like is connected. In addition, a wireless transmission / reception unit 8 having an antenna 8a is connected to the terminal control unit 4, and various signals (data) are exchanged with the controller 3 via the wireless transmission / reception unit 8 as wireless signals. It has become. The security terminal 2 includes a battery 9 (primary battery), and power is supplied from the battery 9 to each unit via the terminal control unit 4.

  The security terminal 2 operates on the battery 9 and can transmit and receive signals wirelessly by the wireless transmission / reception unit 8, and determines whether the wireless security system 1 is warned or released from a return signal received from the controller 3 after transmission. However, it operates continuously during alertness. Further, the operation of the security terminal 2 is invalidated for a predetermined time t1 and t2 stored in advance in the storage unit 4b during the release, or the operation is invalidated for a predetermined time t3 until the user operation. It is like that.

  The controller 3 is installed at a predetermined position of the security target facility, such as a security guard room, and is connected to a controller control unit (a control unit in the figure) having a CPU and a storage unit (not shown) and the controller control unit. A wireless transmission / reception unit having an antenna 10 connected, a notification unit connected to a security center of a security company through a wireless line, and connected to the input side of the controller control unit, for example, the wireless security system 1 can be set to warning and release An operation unit, a display unit capable of displaying various information, a power supply unit, and the like.

  The controller 3 operates with a commercial power source, and various wireless signals (various data) are exchanged with the wireless transmission / reception unit 8 of the security terminal 2 via the wireless transmission / reception unit. Various signals can be exchanged with the security center, and warning or cancellation (cancellation) of the wireless security system 1 can be set by the operation unit or an external control device.

  2 to 4 show a first embodiment of the wireless security system 1. The wireless security system according to the first embodiment is a security system in which only the abnormal signal S1 is transmitted from the security terminal 2 to the controller 3, as shown in the schematic diagram of FIG. In the case of this wireless security system 1, when the sensor unit 5 of the security terminal 2 detects an intruder or the like in the security area, an abnormal signal S1 is transmitted (1) to the controller 3, and the controller 3 receives this abnormal signal S1. Then, when the wireless security system 1 is released, a release signal S2 shown in FIG. 2A is returned (2) to the security terminal 2, and when the wireless security system 1 is an alert, the security terminal 2 is returned. A warning signal S3 shown in FIG. 2B is returned (2).

  Then, as shown in FIG. 2A, when the release signal S2 is returned from the controller 3, the security terminal 2 disables the security terminal 2 for a predetermined time t1 (3). This invalidity means that power from the battery 9 of the security terminal 2 to the sensor unit 5, the switch unit 6, the display unit 7, the wireless transmission / reception unit 8, etc. (hereinafter referred to as the sensor unit 5) via the terminal control unit 4. This is done by stopping the supply, whereby the interrupt processing from the sensor unit 5 to the CPU 4a of the terminal control unit 4 is canceled for a fixed time t1. Further, as shown in FIG. 2B, when the warning signal S3 is returned from the controller 3, the state in which power is supplied from the battery 9 of the security terminal 2 to the sensor unit 5 or the like is maintained, and the terminal control is performed. The interrupt process from the sensor unit 5 to the CPU 4a of the unit 4 remains valid (3).

This operation is specifically shown in the timing chart of FIG. 3 and the flowchart of FIG. This will be described below. The flowchart shown in FIG. 4 is automatically executed in accordance with a program stored in advance in the storage unit 4b of the terminal control unit 4 (the same applies to the flowcharts of FIGS. 7, 9, and 12 below). ). First, as shown in FIG. 4, when the program is started (S100), for example, when the security terminal 2 is turned on, the CPU 4a of the terminal control unit 4 shifts to the low power consumption mode (S101). This low power consumption mode is a mode that suppresses the power consumption of the security terminal 2. When the interrupt process of the CPU 4a of the terminal control unit 4 to be described later is valid, the sensor unit 5 can be input and the interrupt process is performed. In the case of invalidity, the input of the sensor unit 5 is canceled.

  When the mode is shifted to the low power consumption mode in step S101, it is determined whether or not there is an input from the sensor unit 5 (S102). If “YES” in this determination S102, that is, a person has entered the warning area and detected. When a factor is generated and detected by the sensor unit 5 and a detection signal is input to the terminal control unit 4, the low power consumption mode of the CPU 4a is canceled (S103), and the abnormal signal S1 is transmitted to the wireless transmission / reception unit 8 Is transmitted to the controller 3 via S (S104). When the abnormal signal S1 is transmitted to the controller 3, it is determined whether or not a reply signal as a response signal of the abnormal signal S1 is received from the controller 3 (S105). If this determination S105 is “YES”, that is, a security terminal. When a reply signal based on the abnormality signal S1 is returned from the controller 3 after 2 transmits the abnormality signal S1, it is determined whether or not the reply signal is in a warning mode (a warning signal S3) (S106).

  In the case of “NO” in this determination S106, that is, when the release signal S2 is returned from the controller 3 and the wireless security system 1 is in the release mode, the CPU 4a of the terminal control unit 4 is shifted to the low power consumption mode (S107), The fixed time t1 is invalid (S108). As described above, the invalidity of the predetermined time t1 is performed by stopping the supply of power from the battery 9 to each unit, and the interrupt process from the sensor unit 5 to the CPU 4a is cancelled. During this fixed time t1, the power consumed by the security terminal 2 is reduced, and the consumption of the battery 9 is suppressed.

  If “NO” in the determination S105, that is, if the return signal is not returned from the controller 3 even if the abnormal signal S1 is transmitted, the process jumps to step S107 to shift to the low power consumption mode. Further, when the determination S102 is “NO”, that is, when the sensor unit 5 does not detect an abnormality, and when the determination S106 is “YES”, that is, the return signal from the controller 3 is the warning signal S3 and the wireless security system 1 In the case of the alert mode, the program is ended (S109).

  That is, in the case of the first embodiment, as shown in FIG. 3, when a detection factor occurs during the release of the wireless security system 1, an abnormal signal S1 is transmitted to the controller 3, and after this transmission, the release signal S2 from the controller 3 is transmitted. Is received and the security terminal 2 receives this, the security terminal 2 becomes invalid for a predetermined time t1 preset in the storage unit 4b of the terminal control unit 4 from this reception. Therefore, even if a detection factor occurs during a certain time t1 (during release), the security terminal 2 is invalidated, and the abnormal signal S1 is transmitted from the wireless transmission / reception unit 8 or the return signal from the controller 3 is received. Or the sensor unit 5 does not perform a detection operation, and the consumption of the battery 9 of the security terminal 2 is suppressed.

  Further, during the alert after the fixed time t1 elapses, the transmission of the abnormal signal S1 and the reception of the alert signal S3 are executed every time the detection factor is generated, and the detection accuracy during the alert is improved. In addition, as the fixed time t1, a settable fixed time that can correspond to the first detection factor after the start of the warning mode is used according to the form of the warning area.

  The security terminal 2 of the first embodiment is suitably used for a heat ray sensor that detects a temperature difference between the background temperature and the body temperature, for example. That is, in the case of a heat ray sensor, while the wireless security system 1 is being released, a person goes back and forth on the sensor side, so that abnormalities are continuously detected and transmitted, and the security terminal 2 is kept constant during the release. By disabling the time t1, the number of detection / transmissions of the terminal 2 is reduced, and consumption of the battery 9 is suppressed.

  Thus, in the wireless security system 1 of the first embodiment, when the return signal transmitted from the controller 3 based on the abnormal signal S1 transmitted from the security terminal 2 is the release signal S2, the security terminal In order to stop the supply of power from the battery 9 to each part of 2 and invalidate the security terminal 2 for a predetermined time t1, a wasteful abnormal signal S1 from the security terminal 2 is transmitted to the controller 3 during release. It is no longer necessary to receive a reply signal from the controller 3, and the operation of the security terminal 2 being released can be reduced as much as possible, and consumption of the battery 9 of the security terminal 2 can be suppressed.

  In particular, when the wireless security system 1 is released, the CPU 4a automatically shifts to the low power consumption mode, and only when a detection signal is input from the sensor unit 5, the low power consumption mode is canceled and shifts to the normal mode. Therefore, the power consumption of the CPU 4a can be effectively suppressed, and the consumption of the battery 9 can be further reduced. Further, when the warning signal S3 is returned from the controller 3 after transmitting the abnormal signal S1, the detection signal is input from the sensor unit 5 while maintaining the low power consumption mode without invalidating the security terminal 2. Therefore, the abnormality signal detected during the warning can be reliably transmitted to the controller 3, and the detection accuracy during the warning can be further improved.

  Furthermore, since the security terminal 2 can determine whether the wireless security system 1 is released or warned by a reply signal returned from the controller 3 based on the abnormal signal S1 transmitted from the security terminal 2, the security terminal 2 The reply signal can be effectively used without adding a new mechanism or the like to 2 and the configuration of the wireless security system 1 can be simplified. As a result, it is possible to provide a highly reliable wireless security system 1 that can simplify the configuration, extend the life of the battery 9 as much as possible, reliably determine the warning status, and sufficiently improve the detection accuracy (alarm). Is possible.

  5 to 9 show a second embodiment of the wireless security system according to the present invention and its modification. Hereinafter, the same parts as those of the first embodiment will be described with the same reference numerals (the same applies to the third embodiment described later). This 2nd Embodiment is a security system which can transmit abnormality signal S1 and abnormality recovery signal S4 from the terminal 2 for security. That is, as schematically shown in FIG. 5A, when the abnormality recovery signal S4 is transmitted (1) from the security terminal 2 to the controller 3, and the controller 3 receives the abnormality recovery signal S4, the wireless security system 1 When is released, a release signal S2 is returned (2) from the controller 3 to the security terminal 2. Then, the security terminal 2 receives the release signal S2 from the controller 3, the power supply from the battery 9 to the sensor unit 5 is suspended for a certain period of time t2, and the security terminal 2 is disabled, Interrupt processing from the sensor unit 5 to the CPU 4a is cancelled.

  Further, as shown in FIG. 5B, when the abnormal signal S1 or the abnormal recovery signal S4 is transmitted (1) from the security terminal 2 and the warning signal S3 is returned (2) from the controller 3, The terminal 2 is kept valid (3), the state in which power is supplied from the battery 9 to the sensor unit 5 and the like is maintained, and the interrupt processing from the sensor unit 5 to the CPU 4a of the terminal control unit 4 is validated. The Further, as shown in FIG. 5C, when the abnormal signal S1 is transmitted (1) from the security terminal 2 and the release signal S3 is returned (2) from the controller 3, the warning signal S3 is transmitted. As in the case, the security terminal 2 remains valid (3).

  This operation is specifically shown in the timing chart of FIG. 6 and the flowchart of FIG. This will be described below. Note that steps in the same part as FIG. 4 in FIG. 7 will be described in a simplified manner (the same applies to FIGS. 9 and 12 below). As shown in FIG. 7, when the program is started by turning on the security terminal 2 (S200), the CPU 4a of the terminal control unit 4 shifts to the low power consumption mode (S201). Then, it is determined whether or not there is an input from the sensor unit 5 (S202). If “YES” in this determination S202, the low power consumption mode of the CPU 4a is canceled (S203), and the abnormal signal S1 is wirelessly transmitted. It transmits to the controller 3 via the transmission / reception part 8 (S204).

  When the abnormal signal S1 is transmitted to the controller 3 in step S204, it is determined whether or not a reply signal is received from the controller 3 (S205). If “YES” in this determination S205, the state of the sensor unit 5 is recovered from the abnormality. It is determined whether or not (S206). In the case of “abnormal recovery” in this determination S206, it is determined whether or not the return signal returned from the controller 3 is in a warning mode (warning signal S3) (S207). If the answer signal is “NO” in this determination S207 and the return signal is the release signal S2, the CPU 4a of the terminal control unit 4 is shifted to the low power consumption mode (S208), and then the security terminal 2 is disabled for a predetermined time t2 (S209). ), The program becomes the end (S210).

  If “NO” in the determination S205, the process jumps to the step S208 to shift to the low power consumption mode, and if “abnormal” occurs in the determination S206, that is, the state of the sensor unit 5 is an abnormal occurrence state. If the response signal from the controller 3 is “YES” in the alert signal S3 (alert mode) in the determination S207, the program is ended (S210).

  That is, in the case of the second embodiment, as shown in FIG. 6, when a detection factor is generated while the wireless security system 1 is released, this detection factor is removed, and the abnormality recovery signal S4 is transmitted to the controller 3. The release signal S2 is transmitted from the controller 3 based on the abnormality recovery signal S4, and the security terminal 2 is invalidated for a predetermined time t2 from the reception of the release signal S2. Therefore, as in the first embodiment, even if a detection factor occurs during a certain time t2 (during release), the security terminal 2 is inactive and in a dormant state, and the radio transmission / reception unit 8 sends an abnormal signal S1. No transmission or reception of a reply signal from the controller 3, etc., and the consumption of the battery 9 of the security terminal 2 can be suppressed. Note that the fixed time t2 is also set to an arbitrarily settable time that can correspond to the first detection factor after the start of the warning mode according to the form of the warning area, similarly to the fixed time t1.

  The security terminal 2 of the second embodiment is suitably used for, for example, a door sensor (magnet sensor) that detects opening and closing of a door. That is, in the case of a door sensor that functions as a door switch for an entrance door, although the number of people entering and exiting is limited, the battery 9 of the security terminal 2 becomes very exhausted if transmission is performed every time the number of operations is relatively large. . Therefore, by suspending the security terminal 2 for a predetermined time t2 that can be arbitrarily set, the number of times of detection and transmission of the terminal 2 is reduced, and consumption of the battery 9 is suppressed.

  In the security terminal 2 of the second embodiment, when the abnormality recovery signal S4 is transmitted and the release signal S2 is received, the security terminal 2 is invalidated for a certain time t2, and the abnormality signal S1 is transmitted and released. When the signal is received, the security terminal 2 is not invalidated. However, as shown in FIG. 8, the process for the abnormality recovery signal S4 and the process for the abnormality signal S1 can be set in reverse.

  That is, as shown in FIG. 8A, when the abnormal signal S1 is transmitted (1) and the release signal S2 is returned (2) from the controller 3, the security terminal 2 is invalidated for a predetermined time t2. Further, as shown in FIG. 8C, when the abnormality recovery signal S4 is transmitted (1) and the release signal is returned (2) from the controller 3, it is effective without invalidating the security terminal 2. Keep (3). As shown in FIG. 9, in the flowchart in this modified example, in the determination S206, when the state of the sensor unit 5 is abnormal, it is determined whether or not the alarm mode is set (S207), and the state of the sensor unit 5 is abnormal. In the case of recovery, the program is the end (S210).

  In the wireless security system 1 according to the second embodiment, substantially the same functions and effects as those of the first embodiment can be obtained, and the battery 9 is disposed at the doorway of a door where people come and go. In a door sensor or the like where the consumption of the battery tends to become intense, the consumption of the battery 9 can be reduced as much as possible to extend its life.

  10 to 12 show a third embodiment of the wireless security system according to the present invention. This 3rd Embodiment is a security system provided with user switch 6a which can transmit abnormal signal S1 and abnormal recovery signal S4 from security terminal 2, and user can operate in security terminal 2. FIG. In this wireless security system 1, as shown in FIG. 10A, an abnormal signal S1 is transmitted (1) from the security terminal 2 to the controller 3, and a release signal S2 is returned from the controller 3 to the security terminal 2 (2 ), The security terminal 2 is stopped (disabled) for a time t3 until the user switch 6a is turned on, and the interrupt process from the sensor unit 5 to the CPU 4a is cancelled.

  Further, as shown in FIG. 10B, when the abnormal signal S1 or the abnormal recovery signal S4 is transmitted (1) from the security terminal 2 and the warning signal S3 is returned (2) from the controller 3, The terminal 2 remains valid (3), and interrupt processing from the sensor unit 5 to the CPU 4a is validated. Further, as shown in FIG. 10C, the user switch 6a of the security terminal 2 is operated, the operation signal is input to the terminal control unit 4 (1), and the abnormality recovery signal S4 is transmitted to the controller 3 (2). When the release signal S3 is returned (3) from the controller 3, the security terminal 2 remains valid (4) as in the case where the warning signal S3 in FIG. 10B is transmitted. The

  This operation is specifically shown in the timing chart of FIG. 11 and the flowchart of FIG. This will be described below. As shown in FIG. 12, when the program is started by turning on the security terminal 2 (S300), the CPU 4a of the terminal control unit 4 shifts to the low power consumption mode (S301). Then, it is determined whether or not there is an input from the sensor unit 5 (S302). If “YES” in this determination S302, the low power consumption mode of the CPU 4a is canceled (S303), and the abnormal signal S1 is wirelessly transmitted. It transmits to the controller 3 via the transmission / reception part 8 (S304).

  When the abnormal signal S1 is transmitted to the controller 3 in step S304, it is determined whether or not a reply signal is received from the controller 3 (S305). If “YES” in this determination S305, the reply signal returned from the controller 3 is determined. Is determined to be in a warning mode (warning signal S3) (S306). If the release signal S2 is returned in this determination S306 and the answer is “NO”, the CPU 4a of the terminal control unit 4 is shifted to the low power consumption mode (S307), the interrupt process of the CPU 4a is disabled (S308), Time t3 is stopped (S309). The time t3 at this time is the time from when the release signal S2 is received from the controller 3 until the user switch 6a of the security terminal 2 is operated.

  Then, when the security terminal 2 stops for a time t3, it is determined whether or not the input from the sensor unit 6 is in an abnormal recovery state (S310). In the case of "abnormal recovery" in this determination S310, that is, the security terminal 2 is in an abnormal recovery state. In the case of the state, a user operation (S311) is performed by the user switch 6a, an interrupt process to the CPU 4a is performed, the CPU 4a cancels the low power consumption mode (S312), and then an abnormality recovery signal S4 is sent to the controller 3. The program is sent (S313), and the program is ended (S317).

  On the other hand, if “abnormality occurs” in the determination S310, that is, if the security terminal 2 is in an abnormal state, a user operation (S314) is performed by the user switch 6a, an interruption process to the CPU 4a is performed, and the CPU 4a is low. The power consumption mode is canceled (S315), the abnormality recovery of the sensor unit 5 is performed (S316), the abnormality signal S4 is transmitted to the controller 3 (S313), and the program is ended (S317). If “NO” in the determination S305, the process jumps to step S307 to shift to the low power consumption mode, and if “YES” in the determination S306, the program is ended (S317).

  That is, in the case of the third embodiment, as shown in FIG. 11, when a detection factor occurs during the release of the wireless security system 1, the abnormal signal S1 is transmitted and the release signal S2 is received from the controller 3, From time t3 until the user operation is performed, the security terminal 2 stops and becomes invalid. Further, the abnormality recovery signal S4 of the security terminal 2 is in a transmission standby state for a time t4 after the user operation is performed until the abnormality recovery signal S4 is transmitted. Thereby, once the abnormal signal S1 is transmitted, the security terminal 2 can be invalidated and the power consumption of the security terminal 2 can be minimized until a recovery operation by the user is performed. Further, when the recovery operation is performed by the user, if the security terminal 2 is already in the recovery state, an immediate transmission is performed. If the recovery terminal is not in the recovery state, the recovery state is entered next (when the waiting time t4 has elapsed). Thus, it is possible to make a reservation so that the abnormality recovery signal S4 can be transmitted.

  The security terminal 2 of the third embodiment is preferably used for a door sensor using a magnet installed on an automatic door. That is, in the case of an automatic door, since an unspecified number of people enter and exit and the number of times of operation of the security terminal 2 is very large, the battery 9 of the security terminal 2 is extremely consumed when transmitted every detection, By transmitting only the first occurrence of anomaly, and then not transmitting the error recovery until the recovery work by the user is performed, and not performing any detection / transmission in the meantime, the current consumption of the battery 9 is reduced. Can be suppressed. That is, transmission / reception in the security terminal 2 is minimized, and the current consumption of the terminal 2 can be made very small.

  In the wireless security system 1 of the third embodiment, basically the same effects can be obtained as in the first embodiment and the second embodiment, and at the entrance and exit of an automatic door in which people are extremely in and out. In a door sensor or the like which is disposed and the battery 9 of the security terminal 2 is likely to be exhausted severely, it is possible to reduce the consumption of the battery 9 as much as possible within a range that does not adversely affect the detection accuracy, thereby extending its life.

  In addition, the configuration of the security terminal 2 and the controller 3 and the operation thereof in each of the above-described embodiments are examples, and other flowcharts that can obtain the same effects as the above-described flowcharts may be employed, The terminal 2 and the controller 3 can be appropriately changed without departing from the gist of each invention according to the present invention, such as another block configuration.

  The present invention can be used for all wireless security systems in which a security terminal and a controller are connected wirelessly.
