DETAILED DESCRIPTION OF THE INVENTION

[0008] As shown in Fig. 1, the locking / unlocking security system A according to this embodiment includes a security sensor B and a communication terminal C. The security sensor B is attached to a locking / unlocking device D, detects the locking / unlocking of the locking / unlocking device D, and wirelessly transmits the detection result to the communication terminal C. The communication terminal C notifies the user of the notification received from the security sensor B on its screen or as a sound.

[0009] The locking / unlocking security system A is a system that uses a security sensor B and a communication terminal C to monitor the locking / unlocking of a locking / unlocking device D. The locking / unlocking security system A realizes home security by notifying the communication terminal C of the locking / unlocking state of the locking / unlocking device D detected by the security sensor B.

[0010] First, the details of the locking / unlocking device D according to this embodiment will be described. The locking / unlocking device D is a mechanical security device that is attached to entrances and windows of a building to prevent intrusion of suspicious persons into the building, and has a built-in security sensor B. As shown in Figs. 2A to 2C, the locking / unlocking device D comes in various types such as a smart crescent X, a smart thumb turn Y, and a smart cremone Z. The types of the locking / unlocking device D are not limited to these, and there are various types such as a smart cam latch.

[0011] As shown in Fig. 2A, the smart crescent X includes a base x1 and an operating lever x2 that houses a security sensor B. The smart crescent X is a locking / unlocking device A that is mainly used to lock windows, and can be switched between a locked state and an unlocked state by operating the operating lever x2.

[0012] As shown in Figure 2B, the smart thumb turn Y includes a base y1 and an operating lever y2 that houses a security sensor B. The smart thumb turn Y is a locking / unlocking device A that is primarily used to lock and unlock doors, and is switched between a locked state and an unlocked state by operating the operating lever y2.

[0013] As shown in Fig. 2C, the smart cremone Z comprises a base z1 and an operating lever z2 that houses a security sensor B and has a locking function. The smart cremone Z is a locking / unlocking device A that is mainly used to lock windows, and the state is switched between locked and unlocked by operating the operating lever z2.

[0014] Although not shown, the smart cam latch has a base and an operating lever without a locking function that houses a security sensor B. The smart cam latch is a locking / unlocking device A that is mainly used to lock windows, and the state can be switched between locked and unlocked by operating the operating lever.

[0015] The security sensor B is a detection device that is incorporated into the locking / unlocking device D and detects whether the locking / unlocking device D is locked or unlocked, and has the function of wirelessly communicating with the communication terminal C. As shown in Figure 1, the security sensor B has an alkaline battery B1 and a sensor board B2. As shown in the figure, the sensor board B2 has a connector 1, a DC / DC converter 2, a 3-axis acceleration sensor 3, a DIP_SW 4, a microcomputer 5, an RF circuit 6, an antenna 7, and an LED 8.

[0016] The security sensor B is also called a crime prevention sensor, and is attached to the entrances and windows of the building to detect any intrusions into the building. The security sensor B is built into the locking / unlocking device D that is provided at the entrances and windows of the building, and when it detects any intrusions into the building, it reports the detection of the intrusion to the outside.

[0017] The alkaline batteries B1 are the power source for the security sensor B. The alkaline batteries B1 are, for example, AAA or AA batteries, and two of them are connected in series to supply 3.0 V (volts) of DC power to the sensor board B2. In this embodiment, two alkaline batteries B1 are used as the power source for the security sensor B, but the power source for the security sensor B is not limited to the alkaline batteries B1.

[0018] The power source for the security sensor B is selected appropriately taking into consideration the trade-off between the external size, battery capacity, and power consumption of the sensor board B2, etc. For example, a button battery or a AAA or AA secondary battery may be used as the power source for the security sensor B.

[0019] The sensor board B2 is the main body (sensor main body) of the security sensor B. The sensor board B2 is a single-layer or multi-layer printed circuit board (electronic circuit board) that exhibits the desired electrical performance (sensor function) based on the DC power supplied from the alkaline battery B1. The sensor board B2 detects intrusions into the building based on the DC power and reports the detection results to the communication terminal C using radio waves.

[0020] The connector 1 mechanically accommodates and holds the alkaline battery B1 and has a pair of power terminals that contact the positive and negative terminals of the alkaline battery B1. The connector 1 receives DC power from the alkaline battery B1 via the pair of power terminals and outputs it to the DC / DC converter 2.

[0021] The DC / DC converter 2 is connected to the connector 1 via a predetermined power line and boosts the DC power supplied from the alkaline battery B1 via the connector 1 and the power line. The DC / DC converter 2 converts the 3.0V DC power (primary power) supplied from the alkaline battery B1 into an operating voltage (circuit power supply voltage) for a power receiving unit such as a microcomputer 5, and supplies the power to the power receiving unit as a circuit power supply. The operating voltage (circuit power supply voltage) is, for example, 5V, which is higher than the output voltage of the alkaline battery B1.

[0022] The three-axis acceleration sensor 3 detects the gravitational acceleration acting on the operating part of the locking / unlocking device D. The three-axis acceleration sensor 3 is an acceleration sensor whose sensitive directions are three orthogonal axes, namely the X-axis, Y-axis, and Z-axis, and detects the gravitational acceleration acting in the X-axis direction, the Y-axis direction, and the Z-axis direction. The three-axis acceleration sensor 3 outputs the detected X-axis acceleration value, the Y-axis acceleration value, and the Z-axis acceleration value to the microcomputer 5.

[0023] The detected X-axis acceleration value, the detected Y-axis acceleration value, and the detected Z-axis acceleration value are physical quantities that indicate the rotation angle θ of the operating part of the locking / unlocking device D. When the locking / unlocking device D is rotated to unlock, the detected X-axis acceleration value, the detected Y-axis acceleration value, and the detected Z-axis acceleration value change uniquely depending on the rotation direction (left or right) and the rotation angle θ.

[0024] The sign (positive or negative) of the change in the detected X-axis acceleration value, the detected Y-axis acceleration value, and the detected Z-axis acceleration value indicates the rotation direction of the operating unit, and the value (amount of change) of the change in the detected X-axis acceleration value, the detected Y-axis acceleration value, and the detected Z-axis acceleration value indicates the rotation angle θ of the operating unit. The three-axis acceleration sensor 3 is a rotation sensor that detects the rotation angle θ of the locking / unlocking device D and outputs the detected X-axis acceleration value, the detected Y-axis acceleration value, and the detected Z-axis acceleration value as detection signals indicating the rotation angle θ.

[0025] The DIP_SW4 is an electronic component that houses multiple slide switches, each with a pair of external connection terminals, and is known as a DIP switch. The DIP_SW4 has three slide switches, corresponding to three binary bits. The DIP_SW4 has a first slide switch corresponding to the first binary bit, a second slide switch corresponding to the second binary bit, and a third slide switch corresponding to the third binary bit.

[0026] In the first to third slide switches, the open state corresponds to, for example, a binary "1," and the closed state corresponds to a binary "0." In the first to third slide switches, the non-conductive state of a pair of external connection terminals corresponds to a binary "1," and the conductive state of a pair of external connection terminals corresponds to a binary "0."

[0027] The setting state of DIP_SW4, that is, the setting states (open / closed states) of the first to third slide switches, corresponds to the type of locking / unlocking device D, as shown in Figure 3. When the first to third bits are all set to "0," this corresponds to a smart crescent (left) with an unlocking direction to the left and an unlocking angle of 8°. When the first bit is set to "1" and the second and third bits are set to "0," this corresponds to a smart cam latch (left) with an unlocking direction to the left and an unlocking angle of 15°.

[0028] When the first and third bits are set to "0" and the second bit is set to "1," it corresponds to the Smart Cremon (Left) with an unlocking direction to the left and an unlocking angle of 10°. When the first and second bits are set to "1" and the third bit is set to "0," it corresponds to the Smart Security Thumbturn (Left) with an unlocking direction to the left and an unlocking angle of 15°. When the first and second bits are set to "0" and the third bit is set to "1," it corresponds to the Smart Crescent (Right) with an unlocking direction to the right and an unlocking angle of 8°.

[0029] The state where the first and third bits are set to "1" and the second bit to "0" corresponds to a smart cam latch (right) with an unlocking direction to the right and an unlocking angle of 15°. The state where the first bit is set to "0" and the second and third bits are set to "1" corresponds to a smart cremone latch (right) with an unlocking direction to the right and an unlocking angle of 10°. The state where all of the first to third bits are set to "1" is unspecified, and the type of the corresponding locking / unlocking device D is not set.

[0030] The Smart Crescent (Left) is a crescent lock that is locked by rotating the operating part to the left, and is a type of locking / unlocking device D that incorporates a security sensor B. The Smart Cam Latch (Left) is a cam latch lock that is unlocked by rotating the operating part 15° to the left, and is a type of locking / unlocking device D that incorporates a security sensor B.

[0031] The Smart Cremon (Left) is a cremon lock that is locked by rotating the operating part 10 degrees to the left, and is a type of locking / unlocking device D that incorporates a security sensor B. The Smart Security Thumbturn (Left) is a thumbturn lock that is locked by rotating the operating part 12 degrees to the left, and is a type of locking / unlocking device D that incorporates a security sensor B.

[0032] The Smart Crescent (Right) is a crescent lock that locks by rotating the operating unit 8 degrees to the right (Right), and is a locking / unlocking device D of a type that incorporates a security sensor B. The Smart Cam Latch (Right) is a cam latch lock that locks by rotating the operating unit 15 degrees to the right (Right), and is a locking / unlocking device D of a type that incorporates a security sensor B. The Smart Cremon (Right) is a cremon lock that locks by rotating the operating unit 10 degrees to the right (Right), and is a locking / unlocking device D of a type that incorporates a security sensor B.

[0033] DIP_SW4 is a lock designation unit that selectively designates the unlocking direction and unlocking angle for a specific locking / unlocking device D into which the security sensor B is incorporated, among the unlocking directions and unlocking angles for multiple types of locking / unlocking devices D. DIP_SW4 is set appropriately by an operator when assembling the security sensor B inside the locking / unlocking device D. When assembling the security sensor B to the smart crescent (left), the operator sets DIP_SW4 to the binary number "000".

[0034] When assembling security sensor B to the smart cam latch (left), the worker sets DIP_SW4 to the binary number "001." When assembling security sensor B to the smart cremone (left), the worker sets DIP_SW4 to the binary number "010."

[0035] When assembling security sensor B to the smart security thumb turn (left), the worker sets DIP_SW4 to the binary number "011." When assembling security sensor B to the smart crescent (right), the worker sets DIP_SW4 to the binary number "100."

[0036] When assembling security sensor B to the smart cam latch (right), the worker sets DIP_SW4 to the binary number "101." When assembling security sensor B to the smart cremone (right), the worker sets DIP_SW4 to the binary number "110."

[0037] The microcomputer 5 is an unlocking determination unit that determines whether the locking / unlocking device D is unlocked based on the rotation angle θ of the locking / unlocking device D. The microcomputer 5 acquires the rotation angle θ of the locking / unlocking device D based on the X-axis acceleration detection value, Y-axis acceleration detection value, and Z-axis acceleration detection value input from the three-axis acceleration sensor 3 (rotation sensor), determines whether the locking / unlocking device D is unlocked based on the rotation angle θ, and generates a notification signal indicating the result of the determination.

[0038] As described above, the rotation direction of the operating part for unlocking, i.e., the unlocking direction, differs between left and right depending on the type of locking / unlocking device D. The rotation angle θ of the operating part for unlocking, i.e., the unlocking angle, also differs depending on the type of locking / unlocking device D.

[0039] The microcomputer 5 stores in advance in an internal memory the correspondence between the setting value of DIP_SW4 shown in Fig. 3 and the type of locking / unlocking device D (i.e., the unlocking direction and unlocking angle) as information (unlocking determination information) for determining the unlocking of the unlocking device B. Based on the setting value of DIP_SW4, the microcomputer 5 reads out from the internal memory the unlocking direction and unlocking angle corresponding to the setting value, and sets the unlocking direction and unlocking angle as the unlocking determination threshold value.

[0040] The microcomputer 5 determines whether the locking / unlocking device D is locked or unlocked based on the rotation angle θ of the locking / unlocking device D and the unlocking determination threshold value obtained from the X-axis acceleration detection value, the Y-axis acceleration detection value, and the Z-axis acceleration detection value of the three-axis acceleration sensor 3, and generates first and second alarm signals indicating the determination result. The microcomputer outputs the first alarm signal to the RF circuit 6 and the second alarm signal to the LED 8.

[0041] The microcomputer 5 also functions as a pairing setting unit that sets up pairing with an external communication terminal C. The microcomputer 5 executes pairing processing based on the unique power supply pattern of the power source supplied from the alkaline battery B1 or the unique fluctuation pattern of the rotation angle θ of the locking / unlocking device D, and establishes pairing with the communication terminal C.

[0042] Once pairing is set up, the microcomputer 5 stores in its internal memory the identification information of the set communication terminal C and pairing completion information indicating that pairing has been completed. Once pairing is complete, the microcomputer 5 performs wireless communication via the RF circuit 6 and the antenna 7 with the communication terminal C as the communication destination.

[0043] The RF circuit 6 performs a predetermined modulation process on the first annunciation signal input from the microcomputer 5 to generate a transmission signal, which is an RF (radio frequency) signal, and outputs the transmission signal to the antenna 7. The transmission signal is, for example, a radio frequency signal that complies with ZigBee (registered trademark), a well-known short-range wireless communication standard. The RF circuit 6 and the antenna 7 constitute a communication unit that communicates with the communication terminal C that has been paired by the pairing process.

[0044] The RF circuit 6 generates a transmission signal by performing signal processing in accordance with ZigBee (registered trademark) on the first notification signal input from the microcomputer 5. The transmission signal does not need to be a high-frequency signal in accordance with ZigBee (registered trademark), and may be one in accordance with other wireless communication standards such as Bluetooth (registered trademark) or Wi-Fi (registered trademark).

[0045] The antenna 7 radiates the transmission signal supplied from the RF circuit 6 into the air as radio waves (transmission waves). The antenna 7 is, for example, a relatively small dielectric antenna, and converts the transmission signal into radio waves (transmission waves) with high efficiency (high output). The RF circuit 6 and the antenna 7 constitute a first notification unit that notifies the communication terminal C of the unlocking of the locking / unlocking device D using radio waves (transmission waves) based on the first notification signal.

[0046] The LED 8 is a light emitting diode (LED) that notifies the communication terminal C of the locking / unlocking of the locking / unlocking device D based on a second notification signal input from the microcomputer 5. The LED 8 visually notifies the outside that the locking / unlocking device D has been locked or unlocked, and for example, flashes when the locking / unlocking device D has been unlocked. The LED 8 is a second notification unit that visually notifies the unlocking of the locking / unlocking device D by emitting light based on the second notification signal.

[0047] The communication terminal C is an electronic device with a communication function, such as a smartphone, tablet terminal, or desktop computer, that is carried by the user of the locking / unlocking security system A. In addition to the function of communicating with the security sensor B, the communication terminal C also has the function of generating various instruction signals to be sent to the security sensor B, and the output function of displaying or sounding signals received from the security sensor B.

[0048] The communication terminal C establishes pairing with the security sensor B through wireless communication with the security sensor B. Once the pairing is established, the communication terminal C performs wireless communication with the security sensor B with which the pairing has been established as the communication destination.

[0049] The operations of the security sensor B and the locking / unlocking device D according to this embodiment will be described with reference to FIGS.

[0050] First, the first pairing process initially performed by the security sensor B will be described with reference to Fig. 4. The security sensor B sets up pairing with the communication terminal C based on the power supply. The microcomputer 5 of the security sensor B determines whether or not circuit power is supplied from the DC / DC converter 2 (step S1), and if the determination is "Yes," determines whether or not pairing with the communication terminal C has already been completed (step S2).

[0051] The supply of circuit power from the DC / DC converter 2 to the microcomputer 5 is governed by whether or not an alkaline battery B1 is attached to the security sensor B. When the alkaline battery B1 is attached to the security sensor B and connected to the connector 1 of the security sensor B, the output power (battery power) of the alkaline battery B1 is supplied to the DC / DC converter 2.

[0052] The DC / DC converter 2 outputs circuit power to the microcomputer 5. When the alkaline battery B1 is not attached to the security sensor B, battery power is not supplied to the DC / DC converter 2, and therefore circuit power is not supplied from the DC / DC converter 2 to the microcomputer 5. The determination in step S1 becomes "Yes" when the alkaline battery B1 is attached to the security sensor B.

[0053] If the determination in step S1 is "Yes," the microcomputer 5 determines whether pairing is not yet established by searching for pairing completion information in the internal memory (step S2). If pairing is completed, that is, if the determination in step S2 is "No," the microcomputer 5 waits until a pairing start instruction is input (step S3).

[0054] When a user of the locking / unlocking security system A attempts to pair a communication terminal C with a security sensor B, the user operates the communication terminal C to send a pairing start command to the security sensor B. The pairing start command is received by the antenna 7 of the security sensor B and input to the microcomputer 5 via the RF circuit 6.

[0055] If pairing is not completed, that is, if the determination in step S2 is "Yes," the microcomputer 5 determines whether a pairing start instruction has been input (step S3). If a pairing start instruction has been input, the determination in step S3 becomes "Yes," so the microcomputer 5 sets its own operation mode to pairing mode, thereby executing pairing with the communication terminal C (step S4), and further causes the LED 8 to flash (step S5).

[0056] When pairing with the communication terminal C is completed (step S6), the microcomputer 5 increases the blinking speed of the LED 8, and then turns off the LED 8 after a predetermined time has elapsed (step S7). The rapid blinking of the LED 8 followed by its turning off is intended to notify the user that the first pairing process has been completed.

[0057] The above is the details of the pairing process (first pairing process) based on the attachment of the alkaline battery B1 to the security sensor B, i.e., the supply of power to the security sensor B. The first pairing process can be performed before the security sensor B is attached to the locking / unlocking device D.

[0058] Since the security sensor B is attached to the locking / unlocking device D with the alkaline battery B1 installed, it is difficult to perform the first pairing process after the security sensor B is attached to the locking / unlocking device D. The second pairing process described below sets up pairing with the communication terminal C based on a unique variation pattern of the rotation angle θ, regardless of whether the alkaline battery B1 is installed.

[0059] Next, the second pairing process will be described with reference to Fig. 5. In the second pairing process, the microcomputer 5 first determines whether a pairing start instruction has been input (step S1a). As described above, when the user of the locking / unlocking security system A wants to pair the communication terminal C with the security sensor B, the user operates the communication terminal C to send a pairing start instruction to the security sensor B.

[0060] The pairing start instruction is received by the antenna 7 of the security sensor B and input to the microcomputer 5 via the RF circuit 6. When the pairing start instruction is input from the RF circuit 6 and the determination in step S1a is "Yes," the microcomputer 5 detects the rotation angle θ of the locking / unlocking device D based on the detected X-axis acceleration value, the detected Y-axis acceleration value, and the detected Z-axis acceleration value input from the triaxial acceleration sensor 3, and determines whether the rotation angle θ, i.e., the locking / unlocking operation of the locking / unlocking device D, has an unusual fluctuation pattern (step S2a).

[0061] The variation pattern is a pattern in which a predetermined number of locking and unlocking operations are performed within a predetermined period. The predetermined period is, for example, 5 seconds, and the predetermined number of sets is, for example, 10 sets (10 times). In step S2a, the microcomputer 5 determines whether the locking / unlocking device D has repeatedly locked and unlocked 10 times within 5 seconds based on the rotation angle θ.

[0062] If the determination in step S2a is "Yes," the microcomputer 5 sets its own operating mode to pairing mode, thereby executing pairing with the communication terminal C (step S3a), and then causes the LED 8 to blink (step S4a). When the pairing with the communication terminal C is completed (step S5a), the microcomputer 5 increases the blinking speed of the LED 8, and then turns off the LED 8 after a predetermined time has elapsed (step S6a). The rapid blinking of the LED 8 followed by its turning off notifies the user that the second pairing process is complete.

[0063] The above is the details of the pairing process (second pairing process) based on the unique variation pattern of the rotation angle θ. Next, the process of re-pairing with communication terminal C (third pairing process) will be described with reference to Fig. 6. The third pairing process is to cancel pairing with communication terminal C and perform re-pairing with communication terminal C when intermittent power supply is detected a predetermined number of times within a predetermined period of time for the power source.

[0064] First, the microcomputer 5 determines whether or not the alkaline battery B1 has been inserted or removed from the security sensor B (step S1b). The microcomputer 5 determines whether or not the alkaline battery B1 has been inserted or removed from the security sensor B by detecting whether or not three intermittent power supplies have occurred within 30 seconds for the circuit power supplied from the DC / DC converter 2.

[0065] When a user of the locking / unlocking security system A wishes to cancel the pairing with the communication terminal C that has already been set up and to set up a new pairing with the communication terminal C, the user inserts and removes the alkaline battery B1 into and from the security sensor B three times within 30 seconds. The predetermined period in the third pairing process is 30 seconds, and the predetermined number of times is three.

[0066] When the determination in step S1b becomes "Yes," the microcomputer 5 cancels the pairing with the communication terminal C (step S2b), and then performs re-pairing with the communication terminal C (step S3b). The microcomputer 5 also blinks the LED 8 (step S4b) to notify the user of the locking / unlocking security system A that re-pairing is being performed.

[0067] When re-pairing with communication terminal C is completed (step S5b), microcomputer 5 increases the blinking speed of LED 8 and turns off LED 8 after a predetermined time has elapsed (step S6b). The rapid blinking and then turning off of LED 8 notifies the user that the third pairing process is completed.

[0068] When pairing or re-pairing between the security sensor B and the communication terminal C is completed, the microcomputer 5 executes normal processing. The normal processing of the security sensor B will be described below with reference to FIG.

[0069] In normal processing, the microcomputer 5 first reads the setting value from the DIP_SW4 (step S1c). The setting value is set in advance by the user of the locking / unlocking security system A. For example, when incorporating the security sensor B into the smart crescent X, the operator sets the DIP_SW4 to "000."

[0070] The microcomputer 5 determines whether the locking / unlocking device D is locked or unlocked based on the setting value of the DIP_SW4, and notifies the communication terminal C of the determination result. In the normal operating state of the security sensor B in which power is supplied from the alkaline battery B1 to the sensor board B2, the microcomputer 5 reads the setting value of the DIP_SW4.

[0071] Based on the setting value of DIP_SW4, the microcomputer 5 reads out the unlocking direction and unlocking angle corresponding to the setting value from the internal memory and sets them as the unlocking determination threshold value (step S2c). The processing of steps S1c and S2c is the initial setting in the normal processing.

[0072] After the initial setting is completed, the microcomputer 5 acquires the rotation angle θ at predetermined time intervals (step S3c). The microcomputer 5 acquires the rotation angle θ of the operation unit based on the detected X-axis acceleration value, the detected Y-axis acceleration value, and the detected Z-axis acceleration value input from the triaxial acceleration sensor 3.

[0073] The microcomputer 5 performs an unlocking determination by comparing the acquired rotation angle θ with the unlocking determination threshold value set in step S2c, i.e., the unlocking direction and unlocking angle (step S4c). The microcomputer 5 determines that the locking / unlocking device D is unlocked when the sign (positive or negative) of the rotation angle θ matches the unlocking direction and the value of the rotation angle θ exceeds the unlocking angle.

[0074] For example, in the case of the Smart Crescent (Left), the locking direction is to the left, and by rotating the operation unit 8 degrees to the right, the locked state is released and the Smart Crescent (Left) is unlocked. The microcomputer 5 reads the unlocking direction and unlocking angle of the Smart Crescent (Left) from the internal memory based on the setting value of DIP_SW4, and sets them as the unlocking determination threshold value, thereby determining whether the Smart Crescent (Left) is unlocked.

[0075] On the other hand, if the sign (positive or negative) of the rotation angle θ does not match the unlocking direction, or if it matches but the value of the rotation angle θ does not exceed the unlocking angle, the microcomputer 5 determines that the locking / unlocking device D is not unlocked.

[0076] If the sign (positive or negative) of the rotation angle θ matches the unlocking direction and the value of the rotation angle θ exceeds the unlocking angle, the result of the unlocking determination in step S4c will be "Yes." If the sign (positive or negative) of the rotation angle θ does not match the unlocking direction, or if it matches but the value of the rotation angle θ does not exceed the unlocking angle, the result of the unlocking determination in step S4c will be "No."

[0077] When the result of the unlocking determination in step S4c is "Yes," the microcomputer 5 generates a first alarm signal and outputs it to the RF circuit 6 (step S5c). The RF circuit 6 generates a transmission signal based on the first alarm signal and supplies power to the antenna 7 (step S6c). The antenna 7 emits a transmission wave (radio wave) based on the transmission signal toward the external terminal (step S7c).

[0078] Although not shown in Fig. 7, when the result of the unlocking determination is "Yes", the microcomputer 5 generates a second alarm signal in addition to the first alarm signal and outputs it to the LED 8. When the second alarm signal is input from the microcomputer 5, the LED 8 starts to light up to indicate that the locking / unlocking device D is unlocked.

[0079] After notifying the communication terminal C of the unlocking of the locking / unlocking device D, the microcomputer 5 subsequently repeats the process of step S3c. The process of step S3c is also repeated if the unlocking determination of step S4c is "No." The series of processes from step S3c to S7c is a regular process of the microcomputer 5, and is repeated at predetermined time intervals.

[0080] According to this embodiment, it is possible to provide a security sensor B that can be paired without using a dedicated pairing switch, a locking / unlocking device D that includes the security sensor B, and a locking / unlocking security system A.

[0081] The present disclosure is not limited to the above-described embodiment, and various modifications are possible.

[0082] (1) For the security sensor B according to this embodiment, the predetermined period in the second pairing process is not limited to 5 seconds, and the predetermined set is not limited to 10 sets (10 times). The predetermined period and the predetermined set may be any value that would not occur during normal operation of the locking / unlocking device D so as to prevent erroneous pairing.

[0083] (2) For the security sensor B according to this embodiment, the predetermined period in the third pairing process is not limited to 30 seconds, and the predetermined number of times is not limited to 3. The predetermined period and the predetermined number of times may be any number of times that the alkaline battery B1 is inserted and removed so as not to erroneously start re-pairing.

[0084] (3) The rotation sensor of the present disclosure is not limited to the triaxial acceleration sensor 3 that outputs detected X-axis, Y-axis, and Z-axis acceleration values ​​as detection signals. For example, a sensor that detects the rotation angle θ of the locking / unlocking device D as a physical quantity other than triaxial acceleration may be used as the rotation sensor.

[0085] (4) The notification unit of the present disclosure is not limited to the first notification unit that is configured by the RF circuit 6 and the antenna 7 and that uses radio waves (transmission waves) to notify the communication terminal C of the unlocking of the locking / unlocking device D. A notification unit that uses a communication medium other than radio waves, such as light or sound waves, to notify the communication terminal C of the unlocking of the locking / unlocking device D may also be employed.

[0086] (5) The notification unit of the present disclosure is not limited to the LED 8 that emits light to notify the outside that the locking / unlocking device D has been unlocked. For example, instead of the LED 8, a sound generating device such as a buzzer may be used as the notification unit. [Explanation of symbols]
