Description

[Technical field]

[0001] The present technology relates to an alarm controller that controls the operation of an alarm device. [Background technology]

[0002] A security system has been proposed that includes multiple normally-closed sensors that are connected in series to form a closed loop, and an alarm switch for starting alarm (see Patent Document 1). When the alarm switch is turned on, alarm starts after a predetermined delay time has elapsed. Therefore, the user can retreat outside the detection range of the sensor within the delay time.

[0003] [Patent Document 1] JP 2004-178103 A Summary of the Invention [Problem to be solved by the invention]

[0004] Some users may wish to begin being alerted immediately.

[0005] The present disclosure has been made in consideration of the above circumstances, and aims to provide an alarm controller that can start alerting at a desired timing. [Means for solving the problem]

[0006] An alarm controller according to one embodiment of the present disclosure comprises a control board which controls an alarm based on detection results obtained from a detector which detects abnormalities, a selection switch connected to the control board and which selects whether to start or stop control of the alarm, and a designation switch which designates either a first control method which starts control of the alarm after a first predetermined time has elapsed if the selection switch selects to start control of the alarm, or a second control method which starts control of the alarm if the selection switch selects to start control of the alarm, and the control board starts control of the alarm using the first control method if the designation switch designates the first control method, and starts control of the alarm using the second control method if the designation switch designates the second control method.

[0007] In one embodiment of the present disclosure, after a user selects to begin controlling the alarm, the alarm controller will either arm after a first predetermined time period or immediately, depending on the user's selection.

[0008] In one embodiment of the alarm controller of the present disclosure, the selection switch includes a first selection switch positioned within the detection range of the detector and a second selection switch positioned outside the detection range of the detector, and the first control method is a method of starting control of the alarm after the first predetermined time has elapsed if the first selection switch selects to start control of the alarm, and the second control method is a method of starting control of the alarm if the second selection switch selects to start control of the alarm.

[0009] In one embodiment of the present disclosure, when start of alarm control is selected by a first selection switch located within the detection range of the detector, alarming begins after a first predetermined time has elapsed, and when start of alarm control is selected by a second selection switch located outside the detection range of the detector, alarming begins immediately.

[0010] In an alarm controller according to one embodiment of the present disclosure, the control board executes a first determination process of determining whether a predetermined second predetermined time has elapsed since the detection result indicating the abnormality was obtained from the detector when the designation switch designates the first control method and control of the alarm has begun after the first predetermined time has elapsed, a second determination process of determining whether a detection result indicating the abnormality has been obtained if it is determined in the first determination process that the second predetermined time has elapsed, and a process of activating the alarm if it is determined in the second determination process that a detection result indicating the abnormality has been obtained.

[0011] In one embodiment of the present disclosure, after detecting an abnormality, the controller waits for a second predetermined time to elapse and then determines whether an abnormality is detected again. If an abnormality is detected again, the alarm is activated.

[0012] An alarm controller according to one embodiment of the present disclosure comprises a voltage converter that converts an AC voltage input from a commercial power source into a DC voltage, a first output terminal connected to the voltage converter and outputting the DC voltage, and a second output terminal connected to the commercial power source via a relay board, the DC voltage being supplied from the first output terminal to the detector, and when the detector detects an abnormality, the control board outputs a control output signal to the relay board, and the AC voltage of the commercial power source is supplied to the alarm from the second output terminal.

[0013] In one embodiment of the present disclosure, a commercial power supply voltage is supplied to an alarm device driven by an AC voltage, such as a warning light, and a constant DC voltage is supplied to a detector driven by a DC voltage.

[0014] An alarm controller according to one embodiment of the present disclosure is provided with a third selection switch for selecting whether or not to repeatedly activate the alarm, and when the control board selects via the third selection switch to repeatedly activate the alarm, it activates the alarm for a predetermined activation time, and after the activation time has elapsed, repeats the process of stopping the alarm for a stop time.

[0015] In one embodiment of the present disclosure, after activation of the alarm device begins, activation of the alarm device continues intermittently. Effect of the Invention

[0016] In an alarm controller according to one embodiment of the present disclosure, after a user selects to start control of an alarm device, the alarm controller will either begin alerting after a first predetermined time has elapsed or immediately, depending on the user's selection, allowing the user to cause the alarm controller to begin alerting at the desired timing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] (Embodiment 1) The present invention will be described below with reference to the drawings showing an alarm controller 1 according to embodiment 1. Fig. 1 is a block diagram of the alarm controller 1. The alarm controller 1 includes a control board 2, a sensor board 3, a first selection switch 4, a second selection switch 5, a designation switch 6, a voltage converter 7, a first output terminal 8, a relay 9, a second output terminal 10, a terminal block 11, a display board 12, and the like.

[0019] The control board 2 includes a processor (e.g., CPU, MPU, etc.), a main memory (e.g., RAM), an auxiliary memory (e.g., ROM, EEPROM, flash memory, etc.), a VRM, and a timer. A control program, a first and second predetermined time, a drive time, and a stop time are stored in advance in the auxiliary memory. A user can change the first and second predetermined time, the drive time, and the stop time by operating an operation unit (not shown). The processor reads the control program from the auxiliary memory to the main memory and executes the control program. The VRM converts the voltage supplied from the voltage converter 7 into a drive voltage for the processor and supplies it to the processor. Note that a logic circuit (e.g., FPGA, ASIC, etc.) may be provided instead of the processor.

[0020] Power is supplied to the control board 2 from a commercial power source 23 via a voltage converter 7. The commercial power source 23 is, for example, an AC 100V power source. The voltage converter 7 converts, for example, the AC 100V supplied from the commercial power source 23 into a predetermined AC low voltage, and further converts the AC low voltage into DC 24V, DC 12V, DC 5V or DC 3.3V, and supplies it to the control board 2, the sensor board 3 and the first output terminal. A display board 12 is connected to the control board 2. The display board 12 is provided with, for example, an alert lamp that indicates whether or not an alert is being activated. The alert lamp is disposed, for example, near the first selection switch 4. When control of the alarm 25 and the notification device 26 is being executed, the alert lamp is turned on, and when control of the alarm 25 and the notification device 26 is not being executed, the alert lamp is turned off.

[0021] The sensor board 3 is connected to the control board 2. The sensor board 3 is provided with an indicator light that turns on when the sensor detects an abnormality and turns off when the sensor does not detect an abnormality. The indicator light is disposed, for example, near the first selection switch 4.

[0022] The first sensor 21 and the second sensor 22 are connected in series to the sensor board 3 so as to form a closed loop. The first sensor 21 and the second sensor 22 are equipped with normally closed switches, i.e., B-contact switches. The first sensor 21 is a human presence sensor that uses, for example, infrared rays or ultrasonic waves, and is a sensor that requires a supply of power in order to output infrared rays or ultrasonic waves. The first sensor 21 is connected to the first output terminal 8, and power is supplied to the first sensor 21 via the first output terminal 8. The first sensor 21 is installed, for example, in a room in which the alarm controller 1 is installed, and detects the presence or absence of an intruder in the room. When the B-contact switch is open, the first sensor 21 detects the presence of an intruder in the room, i.e., an abnormality.

[0023] The first sensor 21 may be, for example, a vibration sensor installed in a currency exchange machine in a coin laundry. The front of the currency exchange machine faces a washing and drying room in which washing machines and dryers are installed, and the back of the currency exchange machine faces the back yard, i.e., the room in which the alarm controller 1 is installed. In other words, the first sensor 21 is installed in the room in which the alarm controller 1 is installed. When the B-contact switch is open, the first sensor 21 detects that the currency exchange machine has been forced open, i.e., that an abnormality has occurred.

[0024] The second sensor 22 is, for example, a magnet sensor, and is a sensor that does not require a power supply. The second sensor 22 is installed, for example, on a window of a room in which the alarm controller 1 is installed, that is, installed in the room in which the alarm controller 1 is installed, and detects whether the window is open or closed. When the B-contact switch is open, the second sensor 22 detects that the window is open, that is, an abnormality. The number of sensors is not limited to two, and may be one, or three or more. The first sensor 21 and the second sensor 22 constitute a detector.

[0025] The first selection switch 4 and the second selection switch 5 are switches that select starting or stopping control of the alarm 25, and are connected in parallel to the sensor board 3. The first selection switch 4 and the second selection switch 5 may be connected to the control board 2. The first selection switch 4 and the second selection switch 5 are normally open switches, i.e., A-contact switches, and when the A-contact switch is closed, it selects starting control of the alarm 25, and when the A-contact switch is open, it selects stopping control of the alarm 25. When the A-contact switch is closed, the first selection switch 4 and the second selection switch 5 are turned on, and when the A-contact switch is open, the first selection switch 4 and the second selection switch 5 are turned off.

[0026] The first selection switch 4 is installed in the room in which the alarm controller 1 is installed, for example, in the same manner as the first sensor 21 and the second sensor 22. That is, the first selection switch 4 is installed within the detection range of the first sensor 21 and the second sensor 22. The second selection switch 5 is installed outside the room, for example, outside a door provided at the entrance to the room. That is, the second selection switch 5 is installed outside the detection range of the first sensor 21 and the second sensor 22. For example, after going outside the room, the user can lock the door and operate the second selection switch 5 to select the start of control of the alarm device 25. Note that the second selection switch 5 may be operated in conjunction with the locking or unlocking of the door to select the start or stop of control of the alarm device 25.

[0027] The designation switch 6 is a switch that designates either the first control method or the second control method. The designation switch 6 is connected to the sensor board 3. The designation switch 6 may also be connected to the control board 2. The first control method is a control method that starts control of the alarm device 25 and the notification device 26 after a first predetermined time has elapsed when the first selection switch 4 or the second selection switch 5 selects to start control of the alarm device 25. The second control method is a control method that starts control of the alarm device 25 and the notification device 26 when the first selection switch 4 or the second selection switch 5 selects to start control of the alarm device 25. The user operates the designation switch 6 to designate either the first control method or the second control method.

[0028] A second output terminal 10 is connected to the control board 2 via a relay 9. The second output terminal 10 is, for example, a female connector. A commercial power supply 23 is connected to the relay 9. A connector 24 of an alarm device 25 is connected to the second output terminal 10. The connector 24 of the alarm device 25 is, for example, a male connector. The alarm device 25 is, for example, a rotating light or a sound generator. The user can install the alarm device 25 simply by connecting the male connector 24 of, for example, a warning light and a sound generator to the female second output terminal 10, which reduces the effort required to install the alarm device 25 compared to connecting wiring to a terminal.

[0029] The relay 9 connects and disconnects the commercial power supply 23 and the second output terminal 10. The control board 2 controls the connection and disconnection by the relay 9. The control board 2, for example, outputs a control output signal to the relay 9 to connect the relay 9, and stops outputting the control output signal to the relay 9 to disconnect the relay 9. When the commercial power supply 23 and the second output terminal 10 are connected, power is supplied from the commercial power supply 23 to the alarm 25.

[0030] A notification device 26 is connected to the control board 2 via the terminal block 11. The notification device 26 is connected to, for example, a server of a security company via a communication network. When the notification device 26 receives a notification command from the control board 2, it transmits a notice indicating the occurrence of an abnormality to the server of the security company, i.e., reports the abnormality. Note that the notification device 26 does not have to be connected to the terminal block 11.

[0031] 2 is a flow chart explaining the alarm processing by the alarm controller 1. The control board 2 determines whether or not the first control method has been specified by the designation switch 6 (S1). If the first control method has been specified (S1: YES), the control board 2 determines whether or not the first selection switch 4 or the second selection switch 5 has been turned on (S2), i.e., whether or not the start of control of the alarm 25 and the notification device 26 has been selected. If the first selection switch 4 or the second selection switch 5 has not been turned on (S2: NO), i.e., if both the first selection switch 4 and the second selection switch 5 are off, the control board 2 returns the process to step S1.

[0032] When the first selection switch 4 or the second selection switch 5 is turned on (S2: YES), i.e. when starting control of the alarm device 25 and the notification device 26 is selected, the control board 2 determines whether or not a first predetermined time has elapsed after selecting to start control of the alarm device 25 and the notification device 26 (S3). If the first predetermined time has not elapsed (S3: NO), the control board 2 returns the process to step S3. If the first predetermined time has elapsed (S3: YES), the control board 2 starts control of the alarm device 25 and the notification device 26 (S4). The control board 2 turns on the warning lamp on the display board 12 when control of the alarm device 25 and the notification device 26 starts.

[0033] When the user specifies the first control method, it is assumed that the user will have enough time to evacuate from the room and will therefore turn on the first selection switch 4. In this embodiment, even if the first selection switch 4 is off, as long as the second selection switch 5 is on, the control board 2 will control the alarm 25 and the notification device 26 using the first control method. For example, even if the user forgets to turn on the first selection switch 4, the control board 2 can control the alarm 25 and the notification device 26 as long as the second selection switch 5 is on after leaving the room.

[0034] The control board 2 determines whether or not an abnormality has been detected by the first sensor 21 or the second sensor 22 (S5). If no abnormality has been detected (S5: NO), the control board 2 returns the process to step S5.

[0035] If an abnormality is detected (S5: YES), the control board 2 determines whether or not a second predetermined time has elapsed since the abnormality was detected in step S5 (S6). Note that the sensor board 3 turns on the indicator light when an abnormality is detected. If the second predetermined time has not elapsed (S6: NO), the control board 2 returns the process to step S6. If the second predetermined time has elapsed (S6: YES), the control board 2 determines whether or not an abnormality has been detected again (S7). If an abnormality is not detected again (S7: NO), the control board 2 returns the process to step S5. If an abnormality is detected again (S7: YES), the control board 2 connects the relay 9 to activate the alarm 25 and transmits a notification command to the notification device 26 (S8).

[0036] After detecting an abnormality, the control board 2 waits for a second predetermined time to elapse, and if an abnormality is detected again, it activates the alarm 25 and sends a notification command to the reporting device 26. In other words, if no abnormality is detected again, the alarm 25 is not activated and the reporting device 26 does not report. Therefore, if the first sensor 21 or the second sensor 22 malfunctions, for example, if a user strikes the coin changer and erroneously activates the first sensor 21, or if a user accidentally touches a window during maintenance and activates the second sensor 22, it is possible to prevent the alarm 25 from being activated and the reporting device 26 from reporting unnecessarily.

[0037] The control board 2 determines whether or not the drive time has elapsed since drive of the alarm 25 and notification by the notification device 26 began in step S8 (S9). If the drive time has elapsed (S9: YES), the control board 2 stops the alarm 25 and the notification device 26 (S11) and ends the processing. When the alarm 25 and notification device 26 are stopped, the control board 2 turns off the warning lamp on the display board 12.

[0038] If the drive time has not elapsed (S9: NO), the control board 2 determines whether the first selection switch 4 and the second selection switch 5 are turned off (S10). If the first selection switch 4 and the second selection switch 5 are not turned off (S10: NO), the control board 2 returns the process to step S9. If the first selection switch 4 and the second selection switch 5 are turned off (S10: YES), the control board 2 stops the alarm 25 and the notification device 26 (S11) and ends the process. When the alarm 25 and the notification device 26 are stopped, the control board 2 turns off the warning lamp on the display board 12. The drive of the alarm 25 and the notification by the notification device 26 continue until the drive time has elapsed.

[0039] In step S1, if the first control method has not been specified (S1: NO), i.e., if the second control method has been specified, the control board 2 determines whether or not the first selection switch 4 or the second selection switch 5 has been turned on (S12), i.e., whether or not a selection has been made to start control of the alarm 25 and the notification device 26. If the first selection switch 4 or the second selection switch 5 has not been turned on (S12: NO), i.e., if the first selection switch 4 and the second selection switch 5 are off, the control board 2 returns the process to step S1.

[0040] When the first selection switch 4 or the second selection switch 5 is turned on (S12: YES), that is, when starting control of the alarm device 25 and the notification device 26 is selected, the control board 2 starts control of the alarm device 25 and the notification device 26 (S13). When starting control of the alarm device 25 and the notification device 26, the control board 2 turns on the warning lamp on the display board 12. The control board 2 determines whether or not an abnormality has been detected by the first sensor 21 or the second sensor 22 (S14). If no abnormality is detected (S14: NO), the control board 2 returns the process to step S14.

[0041] If an abnormality is detected (S14: YES), the control board 2 connects the relay 9 to drive the alarm 25 and transmits a notification command to the notification device 26 (S15). The sensor board 3 turns on the indicator light when an abnormality is detected. The control board 2 determines whether the first selection switch 4 and the second selection switch 5 are turned off (S16). If the first selection switch 4 and the second selection switch 5 are not turned off (S16: NO), the control board 2 returns the process to step S16. If the first selection switch 4 and the second selection switch 5 are turned off (S16: YES), the control board 2 stops the alarm 25 and the notification device 26 (S11) and ends the process. When the alarm 25 and the notification device 26 are stopped, the control board 2 turns off the warning lamp on the display board 12. The driving of the alarm 25 and the notification by the notification device 26 continue until the first selection switch 4 and the second selection switch 5 are turned off.

[0042] When the user specifies the second control method, it is assumed that the user will not have enough time to evacuate from the room and will therefore turn on the second selection switch 5 installed outside the room. In this embodiment, even when the first selection switch 4 is turned on, the control board 2 can control the alarm 25 and the notification device 26 using the second control method. When the second control method is specified and the first selection switch 4 is turned on, the user is inside the room, so there is a possibility that the presence of the user will be erroneously detected by, for example, the first sensor 21, i.e., an abnormality will be detected.

[0043] By providing an alert lamp and an indicator lamp near the first selection switch 4, the user can confirm that the alert lamp and indicator lamp are lit, recognize that the user's presence has been falsely detected, and turn off the first selection switch 4 and the second selection switch 5 to stop the alarm 25 and the notification device 26. Then, by turning off the first selection switch 4 and leaving the room, and then turning on the second selection switch 5, control of the alarm 25 and the notification device 26 can be started without false detection of the user's presence.

[0044] In an initial state, the designation switch 6 designates the first control method. Even if the user forgets to designate the first control method using the designation switch 6, the designation switch 6 designates the first control method, so that erroneous detection by the first sensor 21 or the second sensor 22 can be suppressed.

[0045] In the alarm controller 1 of embodiment 1, after the user selects to start control of the alarm device 25 and the reporting device 26, the alarm controller 1 will either start alerting after a first predetermined time has elapsed or will start alerting immediately, depending on the user's selection of the first control method or the second control method, allowing the user to cause the alarm controller 1 to start alerting at the desired timing.

[0046] Furthermore, when the start of control of the alarm device 25 and reporting device 26 is selected by the first selection switch 4, which is positioned within the detection ranges of the first sensor 21 and second sensor 22, the alarm controller 1 begins alerting after the first predetermined time has elapsed. When the start of control of the alarm device 25 is selected by the second selection switch 5, which is positioned outside the detection ranges of the first sensor 21 and second sensor 22, the alarm controller 1 begins alerting immediately.

[0047] Furthermore, after detecting an abnormality, the control board 2 waits for a second predetermined time to elapse, and if an abnormality is detected again, it activates the alarm 25 and sends a notification command to the reporting device 26. In other words, if no abnormality is detected again, the alarm 25 is not activated and the reporting device 26 does not report. Therefore, for example, if a user strikes the coin changer and mistakenly activates the first sensor 21, or if a user accidentally bumps into a window during maintenance and activates the second sensor 22, it is possible to prevent the alarm 25 from being activated and the reporting device 26 from reporting unnecessarily.

[0048] Furthermore, the voltage of the commercial power supply 23 is supplied to the alarm device 25 that is driven by AC voltage, such as a warning light and sound generator. A constant DC voltage is supplied to the first sensor 21 and second sensor 22 that are driven by DC voltage. In other words, the alarm controller 1 can supply a voltage suitable for driving the alarm device 25 and sensors. Furthermore, the user can install the alarm device 25 simply by connecting the male connector 24 of, for example, the warning light and sound generator to the female second output terminal 10, which reduces the effort required to install the alarm device 25 compared to when connecting wiring to terminals.

[0049] (Embodiment 2) The present invention will be described below with reference to the drawings showing an alarm controller 1 according to a second embodiment. Fig. 3 is a block diagram of the alarm controller 1. Among the components of the alarm controller 1 according to the second embodiment, the same components as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted. The alarm controller 1 according to the second embodiment has the same components as those in the first embodiment, except that it is provided with a repeat switch 14.

[0050] The alarm controller 1 is equipped with a repeat switch 14. The repeat switch 14 is a switch that selects whether or not to repeat the activation of the alarm device 25 and the notification by the notification device 26. The repeat switch 14 is connected to the sensor board 3. When the repeat switch 14 is on, repeating the activation of the alarm device 25 and the notification by the notification device 26 is selected, and when the repeat switch 14 is off, repeating the activation of the alarm device 25 and the notification by the notification device 26 is not selected. The repeat switch 14 constitutes a third selection switch. The repeat switch 14 may be connected to the control board 2.

[0051] Figures 4 and 5 are flow charts for explaining the alarm processing by the alarm controller 1. The processing in steps S21 to S29, S31, and S35 to S40 shown in Figures 4 and 5 is the same as the processing in steps S1 to S10, S12 to S16, and S11 shown in Figure 2, and detailed explanations thereof will be omitted. Here, the processing in steps S30 and S32 to S34 shown in Figures 4 and 5 will mainly be explained.

[0052] In step S29, if the drive time has elapsed (S29: YES), the control board 2 determines whether or not the repeat switch 14 is on (S30). As described above, the drive time is stored in advance in the auxiliary storage unit. The user can change the drive time. If the repeat switch 14 is not on (S30: NO), that is, if the repeat switch 14 is off, the control board 2 stops the alarm 25 and the notification device 26 (S40) and ends the process.

[0053] In step S30, if the repeat switch 14 is on (S30: YES), the control board 2 stops the alarm 25 and the notification device 26 (S32) and determines whether the first selection switch 4 and the second selection switch 5 are turned off (S33). If the first selection switch 4 and the second selection switch 5 are turned off (S33: YES), the control board 2 ends the process. If the first selection switch 4 and the second selection switch 5 are not turned off (S33: NO), the control board 2 determines whether the stop time has elapsed since the alarm 25 and the notification device 26 were stopped (S34). If the stop time has elapsed (S34: YES), the control board 2 returns the process to step S28. If the second predetermined time has not elapsed (S33: NO), the control board 2 returns the process to step S33.

[0054] In the alarm controller 1 pertaining to embodiment 2, after activation of the alarm device 25 and notification by the notification device 26 have begun, activation of the alarm device 25 and notification by the notification device 26 continue intermittently. This makes it possible to reliably notify those in the vicinity that an abnormality has occurred.

[0055] (Embodiment 3) The present invention will be described below with reference to the drawings showing an alarm controller 1 according to embodiment 3. Among the components of the alarm controller 1 according to embodiment 3, the same components as those in embodiment 1 are given the same reference numerals and detailed description thereof will be omitted. Fig. 6 is a block diagram of the alarm controller 1. The alarm controller 1 according to embodiment 3 has the same configuration as embodiment 1, except that the first selection switch 4 and the second selection switch 5 are each connected to the sensor board 3 individually.

[0056] The alarm processing by the alarm controller 1 in the third embodiment is similar to that in the first embodiment, except for the processing of steps S2, S10, S12, and S16 in the first embodiment (see FIG. 2). In the third embodiment, in step S2, the control board 2 determines whether or not the first selection switch 4 is turned on, in step S10, the control board 2 determines whether or not the first selection switch 4 is turned off, in step S12, the control board 2 determines whether or not the second selection switch 5 is turned on, and in step S16, the control board 2 determines whether or not the second selection switch 5 is turned off.

[0057] In the alarm controller 1 pertaining to embodiment 3, when the start of control of the alarm device 25 and reporting device 26 is selected by the first selection switch 4, which is positioned within the detection ranges of the first sensor 21 and the second sensor 22, the alarm controller 1 begins alerting after the first predetermined time has elapsed. When the start of control of the alarm device 25 is selected by the second selection switch 5, which is positioned outside the detection ranges of the first sensor 21 and the second sensor 22, the alarm controller 1 begins alerting immediately.

[0058] It should be noted that a computer program can be deployed to be executed on a single computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.
