[0003] [Patent Document 1] Patent No. 6155032 Summary of the Invention [Problem to be solved by the invention]

[0004] In monitored areas such as stores and homes, various security devices may be installed, such as transmitters for manually reporting abnormalities to the outside and height measuring devices for measuring the height of intruders. However, in conventional technology, these security devices require individual operations to execute actions in response to abnormalities. Therefore, when an abnormality occurs, users must not only operate the transmitter to report the abnormality to the outside, but also operate the other security devices, which places a heavy operational burden on the user.

[0005] An object of the present invention is to reduce the burden on users of operating a security system when an abnormality occurs. [Means for solving the problem]

[0006] One aspect of the present invention provides a security system comprising a height measurement device that measures the height of a person passing through an entrance or exit of a monitored area, and a transmitting device that transmits a signal in response to operation using an operating unit, wherein the transmitted signal notifies the outside of an abnormality and the height measurement device is controlled to perform an action in response to the abnormality. [Effects of the Invention]

[0007] According to the present invention, it is possible to reduce the burden on the user of operating the security system when an abnormality occurs. [Brief explanation of the drawings]

[0009] 1. First embodiment 1-1.Configuration FIG. 1 is a diagram showing an example of the configuration of a security system 100 according to the first embodiment. The security system 100 is installed in a store such as a convenience store, and is used as a security measure against intruders such as burglars. A store is an example of a monitored area according to the present invention. In the first embodiment, the user of the security system 100 is, for example, a store employee. The security system 100 includes a transmitting device 110, a relay device 120, an automatic door 130, a height measurement device 140, and a paint spraying device 150.

[0010] 2 is a diagram showing an example of the configuration of the transmitting device 110. In response to a user's operation, the transmitting device 110 notifies the outside of an abnormality and transmits a signal to control the automatic door 130, the height measurement device 140, and the paint spraying device 150 to perform operations in response to the abnormality. The transmitting device 110 includes a control unit 111, a storage unit 112, a communication unit 113, and an operation unit 114. The control unit 111 is connected to the storage unit 112, the communication unit 113, and the operation unit 114 via a bus.

[0011] The control unit 111 controls each unit of the transmitting device 110 and performs various processes. The control unit 111 includes a processor such as a CPU. The storage unit 112 stores programs for realizing the functions of the transmitting device 110 and various data. The storage unit 112 includes memories such as RAM and EEPROM. The communication unit 113 communicates with other devices included in the security system 100. This communication may be wireless or wired. The communication unit 113 includes a network adapter, for example. The operation unit 114 is used to operate the transmitting device 110. The operation unit 114 includes push buttons, for example.

[0012] Control unit 111 functions as transmission unit 115. This function is realized by control unit 111 executing a program stored in storage unit 112 to perform calculations or control each unit of transmitting device 110. Note that at least a part of the function of control unit 111 may be realized by a hardware module such as an electronic circuit.

[0013] The transmitter 115 transmits a signal in response to a user's operation using the operation unit 114. The transmitter 115 transmits an alarm signal in response to a first operation performed by the user using the operation unit 114. The first operation is, for example, a short press on the operation unit 114. This alarm signal causes a notification signal to be transmitted to notify the outside of an abnormality, and also controls the automatic door 130, the height measurement device 140, and the paint spray device 150 to transition to an alarm state and perform an operation in response to the abnormality. In other words, the alarm signal serves both as a signal to notify the outside of an abnormality and as a signal to control the automatic door 130, the height measurement device 140, and the paint spray device 150 to perform an operation in response to the abnormality. The alarm signal is an example of a first signal according to the present invention. The operation in response to the abnormality includes reducing the opening / closing speed of the automatic door 130, activating the height measurement device 140, and activating the paint spray device 150.

[0014] Furthermore, the transmitter 115 transmits a release signal in response to a second operation performed by the user using the operation unit 114. The second operation is different from the first operation. For example, the second operation is a long press on the operation unit 114. This release signal causes intruder information 128 indicating the intruder to be transmitted to the outside, and also controls the automatic door 130, the height measurement device 140, and the paint spray device 150 to return from the alarm state to their normal states. In other words, the release signal serves both as a signal for transmitting the intruder information 128 to the server device and as a signal for controlling the automatic door 130, the height measurement device 140, and the paint spray device 150 to return to their normal states. The release signal is an example of a second signal according to the present invention.

[0015] FIG. 3 is a diagram showing an example configuration of relay device 120. Relay device 120 is connected to a server device (not shown) via a communication line such as the Internet. The server device is operated and managed by an organization that deals with abnormalities in response to reports from users, for example. Relay device 120 transmits a notification signal for reporting the abnormality to the outside or intruder information 128 to the server device in response to an operation of transmitting device 110. Relay device 120 includes a control unit 121, a storage unit 122, a first communication unit 123, and a second communication unit 124. Control unit 121 is connected to storage unit 122, first communication unit 123, and second communication unit 124 via a bus.

[0016] The control unit 121 controls each unit of the relay device 120 and performs various processes. The control unit 121 includes a processor such as a CPU. The storage unit 122 stores programs for realizing the functions of the relay device 120 and various data. The storage unit 122 includes memories such as RAM and EEPROM. The first communication unit 123 communicates with other devices included in the security system 100. This communication may be wireless or wired. The first communication unit 123 includes a network adapter, for example. The second communication unit 124 communicates with a server device. The second communication unit 124 includes a network adapter, for example.

[0017] Control unit 121 functions as receiving unit 125, recording unit 126, and transmitting unit 127. These functions are realized by control unit 121 executing a program stored in storage unit 122 to perform calculations or control each unit of relay device 120. Note that at least some of the functions of control unit 121 may be realized by a hardware module such as an electronic circuit.

[0018] The receiving unit 125 receives the alarm signal and the cancellation signal from the transmitting device 110. The receiving unit 125 also receives the height of the intruder from the height measuring device 140.

[0019] The recording unit 126 stores intruder information 128 in the memory unit 122 based on the height received by the receiving unit 125. The intruder information 128 is information about the characteristics, behavior, or status of the intruder. The intruder information 128 is used, for example, to track the intruder.

[0020] FIG. 4 is a diagram illustrating intruder information 128 according to the first embodiment. The intruder information 128 includes a date and time, a height, and a sprayed amount of paint. The date and time indicates the date and time when the intruder's height was measured. For example, a timestamp indicating the date and time when the receiving unit 125 received the height from the height measurement device 140 is used as the date and time. The height is the height of the intruder received by the receiving unit 125. The date and time and height are an example of height-related information according to the present invention. The sprayed amount of paint is the amount of paint sprayed on the intruder by the paint spraying device 150. This sprayed amount is obtained, for example, by multiplying the amount of paint sprayed per time by the paint spraying device 150 by the number of intruders. The amount of paint sprayed per time is determined in advance. The number of intruders is, for example, the heights measured by the height measurement device 140.

[0021] When the alarm signal is received by the receiving unit 125, the transmitting unit 127 transmits a notification signal to the server device. When the receiving unit 125 receives a release signal, the transmitting unit 127 transmits the intruder information 128 stored in the memory unit 122 to the server device.

[0022] Returning to FIG. 1 , the automatic door 130 is installed at the entrance of a store and opens and closes automatically when a person passes through the entrance. The automatic door 130 includes a communication unit 131 and a control unit 132. The communication unit 131 communicates with other devices included in the security system 100. The communication unit 131 receives an alarm signal and a cancellation signal from the transmitting device 110. The control unit 132 adjusts the opening and closing speed of the automatic door 130. The automatic door 130 normally opens and closes at a standard speed. When an alarm signal is received, the control unit 132 reduces the opening and closing speed below the standard speed. When a cancellation signal is received, the control unit 132 returns the opening and closing speed to the standard speed. When the opening and closing speed of the automatic door 130 decreases, the time it takes for the automatic door 130 to open increases. When the opening and closing speed of the automatic door 130 returns to the standard speed, the time it takes for the automatic door 130 to open returns to the original standard time. Therefore, a reduction in the opening and closing speed is an example of an increase in the time it takes for the automatic door to open according to the present invention. The method of increasing the time it takes for the automatic door 130 to open is not limited to slowing down the opening and closing speed, but may be, for example, a method of slowing down the response time of the automatic door 130.

[0023] 5 is a diagram showing an example of the configuration of height measurement device 140. Height measurement device 140 is installed inside the entrance of a store and measures the height of a person passing through the entrance. Height measurement device 140 includes a communication unit 141, a control unit 142, and a line sensor 143. Communication unit 141 communicates with other devices included in security system 100. Communication unit 141 receives an alarm signal and a cancellation signal from transmitting device 110. Communication unit 141 also transmits the height of an intruder measured by control unit 142 and line sensor 143 to relay device 120.

[0024] The control unit 142 controls the operating state of the height measurement device 140. The height measurement device 140 is normally stopped. When an alarm signal is received, the control unit 142 starts the height measurement device 140. When a release signal is received, the control unit 142 stops the height measurement device 140 again. Furthermore, when the height measurement device 140 is started, the control unit 142 measures the height of a person passing through a doorway using the line sensor 143.

[0025] The line sensor 143 includes multiple pairs of light-emitting units 143a and light-receiving units 143b. The multiple light-emitting units 143a are provided at one end of the entrance and are arranged at a predetermined interval, such as 10 cm, along the height direction of a person. Each light-emitting unit 143a emits infrared light. Note that the light emitted by the light-emitting units 143a is not necessarily limited to infrared light. For example, the multiple light-emitting units 143a may each emit visible light of a different color. The multiple light-receiving units 143b are provided at the other end of the entrance and are arranged at a predetermined interval, such as 10 cm, along the height direction of a person. Each light-receiving unit 143b receives infrared light emitted from its corresponding light-emitting unit 143a. When a person passes through the entrance, in the pair of light-emitting unit 143a and light-receiving unit 143b arranged at a height equal to or shorter than the person's height, the infrared light emitted from the light-emitting unit 143a is blocked by the person passing through the entrance and is not received by the light-receiving unit 143b. The control unit 142 determines the height of the light receiving unit 143b that is located at the highest position among the light receiving units 143b that block and do not receive infrared rays as the height of the person passing through the doorway.

[0026] Returning to FIG. 1, the paint spraying device 150 is installed outside the entrance of a store and sprays paint onto a predetermined part of a person passing through the entrance. The paint is, for example, fluorescent paint. The paint is used as a marker for intruders. The predetermined part is, for example, the ankle. The paint spraying device 150 comprises two nozzles 151, a communication unit 152, and a control unit 153. Note that in FIG. 1, the control unit 153 is connected to only one of the two nozzles 151, but in reality, the control unit 153 is connected to both of the two nozzles 151.

[0027] One of the two nozzles 151 is provided at one end of the entrance, and the other nozzle 151 is provided at the other end of the entrance. Each nozzle 151 sprays paint. The communication unit 152 communicates with other devices included in the security system 100. The communication unit 152 receives an alarm signal and a release signal from the transmitting device 110. The communication unit 152 also receives the height of an intruder from the height measuring device 140. The control unit 153 controls the operating state of the paint spraying device 150. The paint spraying device 150 is normally stopped. When the control unit 153 receives an alarm signal, it starts the paint spraying device 150. When the control unit 153 receives a release signal, it stops the paint spraying device 150 again. When stopping the paint spraying device 150, the control unit 153 moves the nozzle 151 to a predetermined position. The predetermined position may be a standby position or a position for replenishing paint. For example, the predetermined position is an upward position.

[0028] Furthermore, when the paint spraying device 150 is activated, the control unit 153 sprays paint onto a predetermined part of the person using the height received from the height measurement device 140. More specifically, the control unit 153 calculates a paint spray angle for spraying paint at a position at the average height of the predetermined part according to the received height. The average height of the predetermined part is determined in advance for each height. The control unit 153 adjusts the angle of the spray nozzle 151 according to the calculated spray angle, and sprays paint from the spray nozzle 151 onto the person passing through the entrance / exit.

[0029] 1-2.Operation 6 is a sequence chart showing an example of the operation of the security system 100 according to the first embodiment. Here, it is assumed that an intruder has broken into a store. In this case, for example, as the intruder flees toward the entrance, the user briefly presses the operation unit 114 of the transmitter 110 to put the security system 100 into an alarm state.

[0030] In step S101, when operation unit 114 is short-pressed, transmission unit 115 of transmitting device 110 transmits an alarm signal to relay device 120, automatic door 130, height measurement device 140, and paint spraying device 150. Receiving unit 125 of relay device 120, communication unit 131 of automatic door 130, communication unit 141 of height measurement device 140, and communication unit 152 of paint spraying device 150 receive the alarm signal from transmitting device 110. In step S102, when the alarm signal is received, transmission unit 127 of relay device 120 transmits a notification signal to the server device.

[0031] In step S103, upon receiving the alarm signal from the transmitting device 110, the control unit 132 of the automatic door 130 reduces the opening / closing speed. For example, if the standard opening / closing speed is V1, the control unit 132 changes the opening / closing speed to V2, which is slower than V1. In step S104, upon receiving the alarm signal from the transmitting device 110, the control unit 142 of the height measurement device 140 activates the height measurement device 140. In step S105, upon receiving the alarm signal from the transmitting device 110, the control unit 153 of the paint spraying device 150 activates the paint spraying device 150.

[0032] When an intruder exits the store through automatic door 130, the opening / closing speed of automatic door 130 is reduced in step S103 described above, and automatic door 130 opens slowly. Therefore, the intruder will pause in front of automatic door 130 and then pass through the entranceway slowly. In step S106, control unit 142 of height measurement device 140 measures the height of the intruder passing through the entranceway slowly using line sensor 143. For example, when an intruder passes through the entranceway, if a pair of light-emitting unit 143a and light-receiving unit 143b is installed at a height higher than 170 cm, infrared light emitted from light-emitting unit 143a will be received by light-receiving unit 143b, whereas if a pair of light-emitting unit 143a and light-receiving unit 143b is installed at a height equal to or lower than 170 cm, the infrared light emitted from light-emitting unit 143a will not be received by light-receiving unit 143b. In this case, control unit 142 will measure the intruder's height as 170 cm. After the height measurement device 140 is activated, if multiple intruders pass through the entrance, the control unit 142 measures the height of each of these intruders.

[0033] In step S107, communication unit 141 of height measurement device 140 transmits the height measured in step S106 to paint spraying device 150. For example, if the intruder's height is 170 cm, communication unit 141 transmits the height of 170 cm. Communication unit 152 of paint spraying device 150 receives the height from height measurement device 140.

[0034] In step S108, control unit 153 of paint spraying device 150 calculates the paint spray angle using the received height. For example, if the intruder's height is 170 cm and the average height from the ankles of a 170 cm person is 10 cm, control unit 153 calculates the paint spray angle for spraying paint at a position 10 cm above the ground. In step S109, control unit 153 of paint spraying device 150 adjusts the angle of nozzle 151 in accordance with the spray angle calculated in step S108, and sprays paint from nozzle 151 at the intruder who is slowly passing through the entrance / exit.

[0035] In step S110, the communication unit 141 of the height measurement device 140 transmits the height measured in step S106 to the relay device 120. The receiving unit 125 of the relay device 120 receives the height from the height measurement device 140. In step S111, the recording unit 126 of the relay device 120 stores intruder information 128 in the memory unit 122 based on the received height. For example, if a height of 170 cm is received at 2:00 AM on April 1, 20XX, the intruder information 128 includes the date and time "2:00 AM on April 1, 20XX" and the height "170 cm," as shown in FIG. 4. In this example, the height measurement device 140 measures one height, so the number of intruders is one. If the amount of paint sprayed per time is 200 ml, the amount of paint sprayed this time is 200 ml × 1 = 200 ml. Therefore, the intruder information 128 includes the spray amount of paint, "200 ml."

[0036] When the intruder leaves the store, the user presses and holds operation unit 114 of transmitting device 110 to cancel the alarm. In step S112, when operation unit 114 is pressed and held, transmission unit 115 of transmitting device 110 transmits a cancellation signal to relay device 120, automatic door 130, height measurement device 140, and paint spraying device 150. Receiving unit 125 of relay device 120, communication unit 131 of automatic door 130, communication unit 141 of height measurement device 140, and communication unit 152 of paint spraying device 150 receive the cancellation signal from transmitting device 110.

[0037] In step S113, upon receiving the release signal from transmitting device 110, control unit 132 of automatic door 130 returns the opening / closing speed to the reference speed. For example, control unit 132 returns the opening / closing speed to V1, which is the reference speed. In step S114, upon receiving the release signal from transmitting device 110, control unit 142 of height measurement device 140 stops height measurement device 140. After height measurement device 140 has stopped, the heights of people passing through the entrance / exit are not measured. In step S115, upon receiving the release signal from transmitting device 110, control unit 153 of paint spraying device 150 moves spray nozzle 151 to a predetermined position and stops paint spraying device 150. After paint spraying device 150 has stopped, paint is not sprayed on people passing through the entrance / exit.

[0038] In step S116, when the transmission unit 127 of the relay device 120 receives the release signal from the transmitting device 110, it transmits the intruder information 128 stored in the memory unit 122 to the server device. This intruder information 128 allows the organization that received the report to know the intruder's height, which can be useful in tracking the escaped intruder. In addition, this intruder information 128 also indicates the amount of paint to be sprayed, which allows the paint spraying device 150 to be replenished with paint as needed.

[0039] According to the first embodiment described above, when an abnormality occurs, the user simply needs to briefly press the operation unit 114 of the transmitting device 110, which sends a notification signal to the server device and activates the height measurement device 140 and the paint spraying device 150, thereby reducing the burden on the user of operating the security system 100 when an abnormality occurs. Furthermore, when the alarm state is canceled, the user simply needs to long press the operation unit 114 of the transmitting device 110, which sends the intruder information 128 to the server device and stops the height measurement device 140 and the paint spraying device 150, thereby reducing the burden on the user of operating the security system 100 when the alarm state is canceled. Furthermore, when the alarm state is canceled, the intruder information 128, including the intruder's height, is sent to the server device, which can be used to track down an escaped intruder.

[0040] Furthermore, since the height measurement device 140 is activated in response to a user's operation, it is possible to prevent the height measurement device 140 from operating when the user does not need it. This makes it possible to prevent unnecessary height information from being acquired and transmitted to the server device. Furthermore, since the paint spraying device 150 is activated in response to a user's operation, it is possible to prevent the paint spraying device 150 from operating when the user does not need it. Furthermore, since the paint spraying device 150 sprays paint at an intruder, it becomes easier to track the intruder.

[0041] 2. Second embodiment 2-1.Configuration FIG. 7 is a diagram showing an example of the configuration of a security system 200 according to the second embodiment. The security system 200 is installed in, for example, an ordinary house, and is used as a security measure against intruders such as burglars. In the second embodiment, the users of the security system 200 are the residents of the house. The security system 200 includes a transmitting device 110, a relay device 120, a plurality of height measurement devices 140, a front door 210, and a gate 220. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and their description will be omitted.

[0042] The multiple height measurement devices 140 are installed at different entrances among multiple entrances, and measure the heights of people passing through the entrances. The multiple entrances include the entrance to the main hall and the entrances to rooms. The multiple height measurement devices 140 include a height measurement device 140-1 installed at the entrance, and height measurement devices 140-2 to 140-4 installed at the entrances to the rooms. The height measurement devices 140 may also be installed at windows. The configuration and operation of each height measurement device 140 are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0043] The front door 210 is installed at the entrance and is opened and closed manually. The front door 210 includes an electronic lock 211, a communication unit 212, and a control unit 213. The electronic lock 211 locks and unlocks the front door 210. The communication unit 212 communicates with other devices included in the security system 200. The communication unit 212 receives a gate arrival signal from the gate 220 indicating that an intruder has reached the gate 220. The communication unit 212 also receives an unlock signal from the transmitting device 110. The control unit 213 controls the electronic lock 211. When the gate arrival signal is received, the control unit 213 controls the electronic lock 211 to lock the front door 210. When the control unit 213 receives the unlock signal, the control unit 213 controls the electronic lock 211 to unlock the front door 210.

[0044] The gate 220 is installed at the outer gate of the entrance and is opened and closed manually. The gate 220 may be any gate that opens and closes the outer entrance of the entrance. For example, the gate 220 may include a parking lot shutter or a double entrance (a hood door) in cold regions. The gate 220 includes an electronic lock 221, a detection unit 222, an audio device 223, a communication unit 224, and a control unit 225. The electronic lock 221 locks or unlocks the gate 220. The detection unit 222 detects an intruder's arrival at the gate 220. The detection unit 222 includes, for example, a vibration sensor. For example, when the vibration sensor detects vibration of the gate 220, the detection unit 222 detects that an intruder has reached the gate 220. The audio device 223 outputs various sounds such as an alarm. The audio device 223 includes, for example, a speaker.

[0045] The communication unit 224 communicates with other devices included in the security system 200. The communication unit 224 receives a detection signal indicating that an intruder has been detected in the house from the relay device 120. The communication unit 212 also receives a release signal from the transmitting device 110. Furthermore, when the detection unit 222 detects that an intruder has reached the gate 220, the communication unit 224 transmits a gate arrival signal to the front door 210. The control unit 225 controls the electronic lock 221. When the intruder detection signal is received, the control unit 225 controls the electronic lock 221 to lock the gate 220. When the release signal is received, the control unit 225 controls the electronic lock 221 to unlock the gate 220. The control unit 225 also controls the audio device 223. When the detection unit 222 detects that an intruder has reached the gate 220, the control unit 225 causes the audio device 223 to output an alarm sound.

[0046] 2-2.Operation 8 is a sequence chart showing an example of the operation of security system 200 according to the second embodiment. Here, it is assumed that an intruder has broken into a house. In this case, for example, when a user of the house notices the intruder or when the intruder runs toward the entrance, the user briefly presses operation unit 114 of transmitting device 110 to put security system 200 into an alarm state.

[0047] In step S201, when operation unit 114 is short-pressed, transmission unit 115 of transmitting device 110 transmits an alarm signal to relay device 120 and height measurement device 140. Receiving unit 125 of relay device 120 and communication unit 141 of height measurement device 140 receive the alarm signal from transmitting device 110. In step S202, when the alarm signal is received, transmission unit 127 of relay device 120 transmits a notification signal to the server device.

[0048] In step S203, upon receiving the alarm signal from the transmitting device 110, the control unit 142 of each height measurement device 140 activates the height measurement device 140. In step S204, when an intruder passes through the entrance or doorway of the room where the height measurement device 140 is installed, the control unit 142 of each height measurement device 140 measures the height of the intruder using the line sensor 143, as in step S106 described above. In step S205, the communication unit 141 of each height measurement device 140 transmits the height measured in step S204 to the relay device 120 together with the identifier of each height measurement device 140. This identifier is assigned to each height measurement device 140 in advance. The receiving unit 125 of the relay device 120 receives the height from each height measurement device 140.

[0049] In step S206, the receiving unit 125 of the relay device 120 transmits an intruder detection signal to the gate 220 when it receives a height for the first time from any of the plurality of height measurement devices 140. The communication unit 224 of the gate 220 receives the intruder detection signal from the relay device 120. In step S207, when the intruder detection signal is received, the control unit 225 of the gate 220 controls the electronic lock 221 to lock the gate 220. In this way, when the height of an intruder passing through the entrance is measured for the first time by any of the plurality of height measurement devices 140, the gate 220 is locked.

[0050] When an intruder leaves the front door of the house and reaches gate 220, he or she attempts to unlock gate 220 and leave the gate. In step S208, detection unit 222 of gate 220 detects the intruder's arrival at gate 220 from vibrations generated when the intruder unlocks gate 220. In step S209, when control unit 225 of gate 220 detects the intruder's arrival at gate 220 in step S208, it causes audio device 223 to output an alarm sound. This alarm sound may be, for example, a signal sound or a voice message indicating that an intruder has entered.

[0051] In step S210, when the communication unit 224 of the gate 220 detects in step S208 that the intruder has reached the gate 220, it transmits a gate arrival signal to the front door 210. The communication unit 212 of the front door 210 receives the gate arrival signal from the gate 220. In step S211, the control unit 213 of the front door 210 controls the electronic lock 211 to lock the front door 210. This prevents the intruder from re-entering the house through the front door. Furthermore, because the gate 220 was also locked in step S207 described above, the intruder is temporarily trapped between the front door 210 and the gate 220.

[0052] In step S212, the recording unit 126 of the relay device 120 stores the intruder information 129 in the memory unit 122. FIG. 9 is a diagram illustrating the intruder information 129 according to the second embodiment. The intruder information 129 includes a date and time, a height, and a movement route. The date and time indicates the date and time when the intruder's height was measured. For the date and time, for example, a timestamp indicating the date and time when the height was received from each height measurement device 140 is used. The height is the height of the intruder received from each height measurement device 140. The movement route indicates the route traveled by the intruder.

[0053] Here, it is assumed that the identifiers of the plurality of height measurement devices 140-1 to 140-4 are "M1" to "M4," respectively. For example, it is assumed that an identifier "M1" and a height of "170 cm" are received from height measurement device 140-1 at 2:00 AM on April 1, 20XX, and then identifiers "M2" to "M4" and heights of "170 cm" are received in order from height measurement devices 140-2 to 140-4, respectively, and finally an identifier "M1" and a height of "170 cm" are received again from height measurement device 140-1. In this case, the intruder information 129 includes the date and time "2:00 AM on April 1, 20XX" and the height of "170 cm." Furthermore, based on the heights and identifiers received from the height measurement devices 140-1 to 140-4 and the order in which they were received, it can be seen that the height measurement devices 140-1 to 140-4 measured the height of the same intruder in the following order: height measurement devices 140-1, 140-2, 140-3, 140-4, 140-1. This means that the intruder moved through the height measurement devices 140 in this order. Therefore, the intruder information 129 includes a movement route of "M1 → M2 → M3 → M4 → M1," which indicates the identifiers of the height measurement devices 140 that the intruder passed through in order. Note that the intruder information 129 may include not only the date and time when the intruder was first measured by the height measurement device 140-1, but also all the dates and times when the intruder's height was measured by the height measurement devices 140-1 to 140-4. These dates and times indicate the dates and times when the intruder passed through each height measurement device 140. These dates and times make it possible to determine when and where the intruder passed through. Therefore, these date and time and travel route are an example of information relating to the travel route according to the present invention.

[0054] When the intruder unlocks gate 220 and exits the gate, the user presses and holds down operation unit 114 of transmitting device 110 to cancel the alarm state. In step S213, when operation unit 114 is pressed and held down, transmission unit 115 of transmitting device 110 transmits a cancellation signal to relay device 120, each height measurement device 140, front door 210, and gate 220. Receiving unit 125 of relay device 120, communication unit 141 of each height measurement device 140, communication unit 212 of front door 210, and communication unit 224 of gate 220 receive the cancellation signal from transmitting device 110.

[0055] In step S214, upon receiving the release signal from the transmitting device 110, the control unit 142 of the height measurement device 140 stops the height measurement device 140. After the height measurement device 140 has stopped, the heights of people passing through the entrance will not be measured. In step S215, upon receiving the release signal from the transmitting device 110, the control unit 213 of the front door 210 controls the electronic lock 211 to unlock the front door 210. In step S216, upon receiving the release signal from the transmitting device 110, the control unit 225 of the gate 220 controls the electronic lock 221 to unlock the gate 220.

[0056] In step S217, upon receiving the release signal from originating device 110, transmitting unit 127 of relay device 120 transmits intruder information 129 stored in storage unit 122 to the server device. This intruder information 129 allows the organization that received the report to know the intruder's height and movement route, which can be useful in tracking the escaped intruder.

[0057] According to the second embodiment described above, when an abnormality occurs, the user simply needs to briefly press operation unit 114 of transmitting device 110, which sends a notification signal to the server device and activates height measurement device 140, thereby reducing the burden on the user of operating security system 200 when an abnormality occurs. Furthermore, when the alarm state is canceled, the user simply needs to long press operation unit 114 of transmitting device 110, which sends intruder information 129 to the server device and stops height measurement device 140, thereby reducing the burden on the user of operating security system 200 when the alarm state is canceled. Furthermore, when the alarm state is canceled, intruder information 129 including the intruder's height and movement route is sent to the server device, so this intruder information 129 can be used to track down an escaped intruder.

[0058] Furthermore, because the height measurement device 140 is activated in response to a user's operation, it is possible to prevent the height measurement device 140 from operating when the user does not need it. This prevents unnecessary height information from being acquired and transmitted to the server device. Furthermore, when an intruder is detected inside the house, the gate 220 is locked, and when the intruder reaches the gate 220, the front door 210 is locked, so that the intruder is temporarily trapped between the front door 210 and the gate 220. At this time, an alarm is output by the sound device 223, making it easier for people outside the house to notice the intruder's intrusion into the house.

[0059] 3. Variations The present invention is not limited to the above-described embodiment. The above-described embodiment is an example, and may be implemented with the following modifications, or may be implemented by combining two or more of the following modifications.

[0060] 3-1. Variation 1 In the first embodiment described above, the alarm signal serves as a signal for causing the relay device 120 to transmit a notification signal, a signal for slowing down the opening / closing speed of the automatic door 130, and a signal for activating the height measurement device 140 and the paint spraying device 150, but these may be separate signals. For example, the transmitting device 110 may transmit a signal for causing the relay device 120 to transmit a notification signal. The transmitting device 110 may also transmit a signal for causing the automatic door 130 to slow down its opening / closing speed. Furthermore, the transmitting device 110 may also transmit a signal for activating the height measurement device 140. Furthermore, the transmitting device 110 may also transmit a signal for activating the paint spraying device 150.

[0061] In the first embodiment described above, the release signal serves as a signal for causing the relay device 120 to transmit the intruder information 128, a signal for returning the opening / closing speed of the automatic door 130 to the reference speed, and a signal for stopping the height measurement device 140 and the paint spray device 150. However, these may be separate signals. For example, the transmitting device 110 may transmit a signal for causing the relay device 120 to transmit the intruder information 128. The transmitting device 110 may also transmit a signal for causing the automatic door 130 to return the opening / closing speed to the reference speed. Furthermore, the transmitting device 110 may transmit a signal for causing the height measurement device 140 to stop. Furthermore, the transmitting device 110 may transmit a signal for causing the paint spray device 150 to stop.

[0062] Similarly, in the second embodiment described above, the signal for causing the relay device 120 to transmit a notification signal and the signal for activating the height measurement device 140 may be separate signals. Also, the signal for causing the relay device 120 to transmit the intruder information 129, the signal for stopping the height measurement device 140, the signal for unlocking the front door 210, and the signal for unlocking the gate 220 may be separate signals.

[0063] In the first embodiment, the signal transmitted from the transmitting device 110 may be transmitted to the automatic door 130, the height measurement device 140, and the paint spraying device 150 via the relay device 120. Similarly, in the second embodiment, the signal transmitted from the transmitting device 110 may be transmitted to the automatic door 130, the height measurement device 140, the front door 210, and the gate door 220 via the relay device 120.

[0064] This modified configuration also reduces the burden on the user of operating the security system 200 when an abnormality occurs and when the alarm state is cancelled.

[0065] 3-2. Variation 2 In the first and second embodiments described above, transmitting device 110 may store intruder information 128 or 129 in memory 112 instead of relay device 120. In this case, height measurement device 140 transmits the height to transmitting device 110. When operation unit 114 is pressed and held, transmitting device 110 transmits intruder information 128 or 129 stored in memory 112 to the server device via relay device 120. Alternatively, if transmitting device 110 is connected to the server device via a communication line such as the Internet, transmitting device 110 may transmit intruder information 128 or 129 stored in memory 112 to the server device when operation unit 114 is pressed and held. Even with the configuration according to this modification, intruder information 128 or 129 can be transmitted to the server device.

[0066] 3-3. Variation 3 In the first and second embodiments described above, the height measurement device 140 is not limited to one that uses the line sensor 143. The height measurement device 140 may also measure the height of an intruder using an ultrasonic sensor. The ultrasonic sensor is installed, for example, on the ceiling of a doorway and uses ultrasonic waves to measure the distance to the top of the head of a person passing through the doorway. The height measurement device 140 measures the height of a person passing through the doorway by subtracting the measured distance from the distance from the floor to the ceiling. The configuration related to this modification can also measure the height of an intruder.

[0067] 3-4. Variation 4 In the first embodiment described above, the height measurement device 140 or the relay device 120 may calculate the paint spray angle according to the height of the intruder instead of the paint spray device 150. In this case, the height measurement device 140 or the relay device 120 transmits the calculated spray angle to the paint spray device 150. Even with the configuration according to this modification, it is possible to spray paint onto a predetermined part of the intruder.

[0068] 3-5. Variation 5 In the first embodiment described above, if the paint spraying device 150 has a function for measuring the amount of paint sprayed, the measured amount of paint sprayed may be transmitted to the relay device 120. In this case, the intruder information 128 may include the amount of paint sprayed received from the paint spraying device 150. This modification allows a more accurate amount of paint sprayed to be determined.

[0069] 3-6. Variation 6 In the first embodiment described above, the location where the paint spraying device 150 is installed is not limited to the outside of the entrance. For example, the paint spraying device 150 may be installed on the ceiling inside the entrance. In this case, the paint spraying device 150 may spray paint onto the back of an intruder who pauses in front of the automatic door 130. This modification makes it difficult for an intruder to notice the paint.

[0070] 3-7. Variation 7 In the first embodiment described above, the paint sprayed by the paint spraying device 150 is not limited to fluorescent paint. The paint may be colorless and transparent so that it is difficult for an intruder to notice. The colorless and transparent paint may be paint that glows in response to black light. The colorless and transparent paint may also have an odor that only a specific animal, such as a dog, or a specific insect can detect. When the colorless and transparent paint with such an odor adheres to an intruder, the intruder can be tracked by the specific animal or insect. Furthermore, the colorless and transparent paint may include a small GPS (Global Positioning System) transmitter and an adhesive that attaches the GPS transmitter to the intruder's clothing. When the GPS transmitter is attached to the intruder, the GPS transmitter transmits the intruder's location information, making it easier to track the intruder.

[0071] 3-8. Variation 8 In the second embodiment described above, the paint spraying device 150 may be installed at the entrance or gate. For example, when the detection unit 222 of the gate 220 detects that an intruder has reached the gate 220, the communication unit 224 of the gate 220 may transmit a gate arrival signal to the paint spraying device 150, causing the paint spraying device 150 to spray paint at the intruder. This modification makes it easier to track the intruder.

[0072] 3-9. Variation 9 In the second embodiment described above, any one of the plurality of height measurement devices 140 may transmit an intruder detection signal to the gate 220 instead of the relay device 120. For example, the height measurement device 140-1 installed at the entrance functions as a master device, and the height measurement devices 140-2 to 140-4 function as slave devices. In this case, when the height measurement devices 140-2 to 140-4 measure the height of an intruder, the height measurement devices 140-2 to 140-4 transmit the measured height to the height measurement device 140-1. When the height of an intruder is measured for the first time by any one of the height measurement devices 140-1 to 140-4, the height measurement device 140-1 transmits an intruder detection signal to the gate 220. This modified configuration can also prevent an intruder from quickly escaping to the outside of the gate.

[0073] 3-10. Variation 10 In the second embodiment described above, gate 220 may further include a light emitting device. When detection unit 222 detects that an intruder has reached gate 220, control unit 225 may cause audio device 223 to emit an alarm sound and light the light emitting device. According to this modification, it is possible to notify people outside the house that an intruder has entered the house.

[0074] 3-11. Variation 11 In the second embodiment described above, the front door 210 and the gate 220 do not necessarily have to be unlocked when the unlocking signal is received. For example, the front door 210 and the gate 220 may be unlocked when a predetermined operation is performed after the unlocking signal is received.

[0075] 3-12. Variation 12 In the second embodiment described above, the security system 200 may include an intercom. When the intercom receives a release signal from the transmitting device 110, it outputs the sound from inside the house to the outside of the house. This allows the resident to use the intercom to call for help from someone outside the house.

[0076] 3-13. Variation 13 In the first and second embodiments described above, the security system 100 or 200 may include a window or light with an electronic lock. When an alarm signal is received from the transmitting device 110, the window may be locked by the electronic lock to lock in an intruder, or conversely, the window may be unlocked by the electronic lock to make it easier for the intruder to escape outside. The light is turned off when an alarm signal is received from the transmitting device 110. In particular, when the light is turned off at night, the intruder's visibility is reduced, so it is expected that the intruder will simply escape outside without committing a burglary. Note that the height measurement device 140 uses a line sensor 143, so the height of the intruder can be measured even when the light is turned off.

[0077] 3-14. Variation 14 In the first and second embodiments described above, the security system 100 or 200 may include other security devices. The other security devices may include, for example, a color sensor that reads the intruder's hair color and clothing color, a weight measuring device that measures the intruder's weight, and a surveillance camera. The color sensor is activated upon receiving an alarm signal from the transmitting device 110, reads the intruder's hair color and clothing color, and transmits the read data to the relay device 120. The weight measuring device is activated upon receiving an alarm signal from the transmitting device 110, measures the intruder's weight, and transmits the measured data to the relay device 120. The surveillance camera is activated upon receiving an alarm signal from the transmitting device 110, takes an image of the intruder, and transmits the image to the relay device 120. In this case, the intruder information 128 or 129 includes the intruder's hair color, clothing color, weight, and image. According to this modification, the intruder's hair color, clothing color, weight, and appearance can be determined.

[0078] 3-15. Variation 15 In the first and second embodiments described above, operation unit 114 of transmitting device 110 is not limited to a push button. For example, operation unit 114 may be a slide switch or a software button displayed on a display unit. Furthermore, the first operation and the second operation of operation unit 114 are not limited to a short press and a long press, respectively, and may be other operations as long as they can be distinguished from each other.

[0079] 3-16. Variation 16 The configurations, functions, and operations of the security system 100 or 200, the transmitter 110, the relay device 120, the automatic door 130, the height measurement device 140, the paint spraying device 150, the entrance door 210, and the gate 220 described in the first and second embodiments are illustrative and are not limited to these. These systems or devices may be configured to include one or more of the devices or components described above, or may be configured without including some of the devices or components. Furthermore, at least some of the functions of these systems or devices may be possessed by other devices. Furthermore, the order of the operation procedures of these systems or devices may be changed, or some operation procedures may be omitted, as long as there is no contradiction.

[0080] 3-17. Variation 17 Another aspect of the present invention may provide a method having operational steps performed in at least one of security system 100 or 200, transmitting device 110, relay device 120, automatic door 130, height measurement device 140, paint spraying device 150, front door 210, and gate 220. Furthermore, yet another aspect of the present invention may provide a program executed in transmitting device 110, relay device 120, automatic door 130, height measurement device 140, paint spraying device 150, front door 210, and gate 220. This program may be provided by being stored in a computer-readable recording medium, or may be provided by downloading via the Internet or the like. [Explanation of symbols]
