[0002] 2. Description of the Related Art Conventionally, there exists a technique for preventing damage to a vehicle by determining whether the vehicle is safe and issuing a warning or alert before an illegal act is committed (for example, Patent Document 1).

[0003] JP 2013-228912 A

[0004] However, the conventional technology is unable to provide appropriate notifications depending on the situation inside and outside the vehicle. For example, in a situation where an alarm is not required for the situation outside the vehicle, it is unable to provide a notification to the outside when a small child or a pet is left inside the vehicle. Thus, the above-mentioned problems are cited as examples of the problems that the present invention aims to solve.

[0005] In order to solve the above-mentioned problems and achieve the object, the invention described in claim 1 is characterized by having an outside-vehicle detection unit that detects moving objects outside the vehicle, an inside-vehicle detection unit that detects moving objects inside the vehicle, and a notification unit that detects the approach of a moving object to the vehicle using the outside-vehicle detection unit and, when the inside-vehicle detection unit detects a moving object inside the vehicle, sends a first notification and a second notification to the outside of the vehicle.

[0006] The invention described in claim 10 is a monitoring method executed by a computer, characterized in that it includes an outside-vehicle detection process for detecting a moving object outside the vehicle, an inside-vehicle detection process for detecting a moving object inside the vehicle, and a notification process for notifying the outside of the vehicle of a first notification and a second notification when the outside-vehicle detection process detects a moving object approaching the vehicle and the inside-vehicle detection process detects a moving object inside the vehicle.

[0007] The invention described in claim 11 is characterized in that a computer executes an outside-vehicle detection step for detecting a moving object outside the vehicle, an inside-vehicle detection step for detecting a moving object inside the vehicle, and a notification step for notifying the outside of the vehicle of a first notification and a second notification if the outside-vehicle detection step detects a moving object approaching the vehicle and the inside-vehicle detection step detects a moving object inside the vehicle.

[0009] Hereinafter, a mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described with reference to the drawings. Note that the present invention is not limited to the embodiment described below. Furthermore, in the description of the drawings, the same parts are given the same reference numerals.

[0010] (Embodiment) [Configuration of Monitoring System] First, the configuration of a monitoring system according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing the configuration of an information processing system according to an embodiment. Fig. 1 shows a monitoring system 1 as an example of an information processing system according to an embodiment.

[0011] 1, the monitoring system 1 may include an in-vehicle device 10 and a monitoring device 100. The in-vehicle device 10 and the monitoring device 100 are connected to each other via a network N so as to be able to communicate with each other via a wired or wireless connection. The monitoring system 1 shown in FIG. 1 may include any number of in-vehicle devices 10 and any number of monitoring devices 100.

[0012] The in-vehicle device 10 may be a dedicated sensor device built into or externally attached to the vehicle VEx, or may be a recording device (drive recorder) or other device installed in the vehicle VEx for crime prevention or to prevent tailgating.

[0013] The in-vehicle device 10 may also be configured with a sensor device and a notification device. As an example, the in-vehicle device 10 may be a composite device in which a sensor device and a notification device that are independent of each other are connected to each other so as to be able to communicate with each other. As another example, the in-vehicle device 10 may be a single device having a sensor function and a notification function.

[0014] Furthermore, a user can connect a predetermined sensor to a portable terminal device (e.g., a smartphone, a tablet terminal, a notebook PC, a desktop PC, a PDA, or the like) that they use on a daily basis and install a predetermined application, thereby substituting the portable terminal device as the in-vehicle device 10. For example, a portable terminal device that is equipped with a predetermined sensor or to which a predetermined sensor is connected can be understood as the in-vehicle device 10 referred to here. When the portable terminal device is used as the in-vehicle device 10, it is installed, for example, on the dashboard of the vehicle VEx while driving.

[0015] The in-vehicle device 10 may also include various sensors. For example, the in-vehicle device 10 may include various sensors such as a distance sensor (a microwave sensor, a LiDAR (light detection and ranging) or other motion sensor), a temperature sensor, a microphone, a GPS sensor, an acceleration sensor, a gyro sensor, a camera, and an air pressure sensor.

[0016] The monitoring device 100 may acquire various types of data based on sensor information detected by these sensors (for example, by analyzing the sensor information). For example, the monitoring device 100 acquires information on moving objects inside and outside the vehicle from a moving object sensor. Also, for example, the monitoring device 100 acquires the temperature inside the vehicle from a temperature sensor. Also, for example, the monitoring device 100 acquires audio from a microphone. Also, for example, the monitoring device 100 acquires angular velocity from a gyro sensor. Also, for example, the monitoring device 100 acquires video data of the outside captured from inside the vehicle VEx by a camera. Note that the monitoring device 100 may acquire sensor information detected not only by sensors provided in the in-vehicle device 10, but also by sensors provided in the vehicle VEx itself.

[0017] The monitoring device 100 is a device that provides notifications according to the situation inside and outside the vehicle. For example, the monitoring device 100 determines the situation from information about moving objects outside the vehicle and information about moving objects inside the vehicle, and provides notifications to outside the vehicle. The monitoring device 100 also captures images inside and outside the vehicle according to the situation inside and outside the vehicle, and transmits the captured images simultaneously with the notification to outside the vehicle.

[0018] Here, if the in-vehicle device 10 is an edge computer that performs edge processing near the user, the monitoring device 100 may be, for example, a cloud computer that performs processing on the cloud side. In other words, the monitoring device 100 may be a server device.

[0019] Furthermore, in the following embodiment, an example is shown in which information processing according to the embodiment is realized in the monitoring system 1 by transmitting and receiving information between the in-vehicle device 10 and the monitoring device 100. However, the information processing according to the embodiment may be realized only on the edge side, i.e., by the in-vehicle device 10. In this case, the in-vehicle device 10 may be configured to behave like the monitoring device 100, for example, by an information processing program according to the embodiment.

[0020] [Configuration of Monitoring Device] First, the monitoring device 100 according to the embodiment will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example configuration of the monitoring device 100 according to the embodiment. As shown in Fig. 2, the monitoring device 100 has a communication unit 110, a storage unit 130, and a control unit 120. Each unit of the monitoring device 100 will be described below.

[0021] The communication unit 110 is realized by, for example, a network interface card (NIC), etc. The communication unit 110 is connected to the network N by wire or wirelessly, and transmits and receives information to and from the in-vehicle device 10, for example.

[0022] The storage unit 130 is realized by, for example, a semiconductor memory element such as RAM (Random Access Memory) or flash memory, or a storage device such as a hard disk or optical disk. The storage unit 130 stores information such as information about moving objects, risk points, temperature information, audio information, information about the target of notification, images (including moving images and still images), notification settings, other information necessary for monitoring, and other information necessary for notification.

[0023] The control unit 120 is realized using a central processing unit (CPU), a network processor (NP), a field programmable gate array (FPGA), or the like, and executes processing programs stored in memory. As shown in Fig. 2, the control unit 120 includes an outside-vehicle detection unit 121, an inside-vehicle detection unit 122, an acquisition unit 123, and a notification unit 124. Each unit included in the control unit 120 will be described below.

[0024] The outside-vehicle detection unit 121 detects a moving object outside the vehicle. For example, the outside-vehicle detection unit 121 detects the approach of a moving object to the vehicle. Examples of the moving object to be detected include a person, a vehicle, a pet, and a wild animal. The outside-vehicle detection unit 121 also detects the approach of a moving object to the vehicle using information on the position and direction. A specific method for detecting a moving object by the outside-vehicle detection unit 121 using information on the position and direction will be described later.

[0025] The interior detection unit 122 detects a moving object inside the vehicle. For example, the interior detection unit 122 detects a predetermined movement of a moving object inside the vehicle. For example, the interior detection unit 122 detects movement that may pose a risk of an accident, such as violent or abnormal movement of a person or pet waiting inside the vehicle.

[0026] The interior detection unit 122 detects a predetermined state inside the vehicle. For example, the interior detection unit 122 detects the movement of a moving object inside the vehicle. For example, the interior detection unit 122 detects the movement of a moving object inside the vehicle to a predetermined position. For example, the interior detection unit 122 detects the movement of a moving object inside the vehicle toward the driver's seat.

[0027] The acquisition unit 123 acquires information related to the vehicle. For example, the acquisition unit 123 acquires the temperature inside the vehicle. For example, the acquisition unit 123 acquires information that the temperature inside the vehicle is 10°C. Also, for example, the acquisition unit 123 acquires information that the temperature inside the vehicle is 32°C.

[0028] The acquisition unit 123 also acquires sounds from inside the vehicle. For example, the acquisition unit 123 acquires the voices of people in the vehicle. For example, the acquisition unit 123 also acquires the cries of pets in the vehicle.

[0029] When the outside-vehicle detection unit 121 detects that a moving object is approaching the vehicle and the inside-vehicle detection unit 122 detects a moving object inside the vehicle, the notification unit 124 sends a first notification and a second notification to the outside of the vehicle. For example, the notification unit 124 issues an audible alarm as the first notification and sends a notification to the user terminal as the second notification.

[0030] For example, the notification unit 124 issues a sound or light alarm around the vehicle as the first notification. Furthermore, for example, the notification unit 124 issues a notification to a pre-registered user terminal as the second notification. The notification to the user terminal includes notifications that can be sent using functions provided in the user terminal, such as email, incoming calls, and notifications to apps.

[0031] The notification unit 124 may issue the same notification as the second notification as the first notification. The notification unit 124 may issue the same notification as the first notification as the second notification. The notification unit 124 may also notify the police or fire department at the same time as the first notification or the second notification.

[0032] Furthermore, the notification unit 124 issues a second notification to the outside of the vehicle when the vehicle exterior detection unit 121 does not detect the approach of a moving object to the vehicle and the vehicle interior detection unit 122 detects a predetermined state inside the vehicle. For example, the notification unit 124 issues a second notification to the outside of the vehicle when the vehicle exterior detection unit 121 does not detect the approach of a moving object to the vehicle and the vehicle interior detection unit 122 detects a moving object inside the vehicle. For example, the notification unit 124 issues a second notification to the outside of the vehicle when the vehicle exterior detection unit 121 does not detect the approach of a moving object to the vehicle and the vehicle interior detection unit 122 detects a predetermined movement of a moving object inside the vehicle.

[0033] Furthermore, for example, when the outside-vehicle detection unit 121 does not detect the approach of a moving object to the vehicle, the inside-vehicle detection unit 122 detects a moving object inside the vehicle, and the temperature inside the vehicle acquired by the acquisition unit 123 exceeds a threshold, the notification unit 124 issues a second notification to the outside of the vehicle. In this case, the notification unit 124 can use a predetermined threshold value, such as when the temperature falls below 0°C or exceeds 35°C, as the threshold value for the temperature inside the vehicle.

[0034] Furthermore, for example, when the vehicle exterior detection unit 121 does not detect the approach of a moving object to the vehicle and the volume of the sound acquired by the acquisition unit 123 exceeds a threshold, the notification unit 124 issues a second notification to the outside of the vehicle. At this time, the notification unit 124 can use a predetermined decibel, such as 80 decibels (dB), as the volume threshold. Furthermore, for example, when the vehicle exterior detection unit 121 does not detect the approach of a moving object to the vehicle, the vehicle interior detection unit 122 detects a moving object inside the vehicle, and the volume of the sound acquired by the acquisition unit 123 exceeds a threshold, the notification unit 124 issues a second notification to the outside of the vehicle.

[0035] Furthermore, for example, when the outside-vehicle detection unit 121 does not detect an approach of a moving object to the vehicle, the inside-vehicle detection unit 122 detects a moving object inside the vehicle, and the notification unit 124 determines that the sound acquired by the acquisition unit 123 is a predetermined type of sound (for example, a child's voice or a pet's bark), the notification unit 124 issues a second notification to the outside of the vehicle. At this time, the notification unit 124 may determine the predetermined type of sound by comparing it with a predetermined frequency pattern, or may determine the type of sound by using a machine learning model to estimate the type of sound using sound information as input.

[0036] Furthermore, for example, when the outside-vehicle detection unit 121 does not detect the approach of a moving object to the vehicle and the inside-vehicle detection unit 122 detects the movement of a moving object inside the vehicle toward the driver's seat, the notification unit 124 issues a second notification to the outside of the vehicle. Furthermore, for example, when the outside-vehicle detection unit 121 does not detect the approach of a moving object to the vehicle and the inside-vehicle detection unit 122 detects the operation of an in-vehicle device, the notification unit 124 issues a second notification to the outside of the vehicle.

[0037] [External Vehicle Detection Process] Next, the external vehicle detection process performed by the monitoring device 100 will be described with reference to Figures 3 and 4. The external vehicle detection unit 121 of the monitoring device 100 detects a moving object outside the vehicle using a moving object sensor such as a distance sensor (microwave sensor, LiDAR, etc.). At this time, as shown in Figure 3, the external vehicle detection unit 121 can perform a risk analysis of the approach of the moving object using information on the position (distance risk) and direction (directional risk). For example, the external vehicle detection unit 121 may perform a risk analysis using a table that multiplies the position and direction, and detect the approach of a moving object to the vehicle when the risk point exceeds a threshold. Note that, as shown in Figure 3, the external vehicle detection performed by the monitoring device 100 targets not only moving objects present to the sides of the vehicle, but also moving objects present around the vehicle, including in the forward and backward directions.

[0038] For example, in Figure 3, if the person moves from "a distance where it can be touched after a short movement" to "the direction of the car (center)," which is "a distance where it can be easily touched," the outside vehicle detection unit 121 analyzes that the distance to the car is getting closer and the movement is toward the center of the car, so the risk point is 6.

[0039] 3, if the vehicle moves from "distance where it can be easily touched" to "parallel to the vehicle," the vehicle exterior detection unit 121 analyzes that the risk point is 4 because the distance to the vehicle is close but the direction of movement is parallel to the vehicle. Also, if the vehicle moves from "distance where it can be touched after a short movement" to "opposite the vehicle" to "distance where it cannot be touched" in FIG. 3, the vehicle exterior detection unit 121 analyzes that the risk point is 1 because the distance to the vehicle is far and the direction of movement is opposite to the vehicle.

[0040] The vehicle exterior detection unit 121 may calculate risk points by various calculations, such as sum or product, using distance risk and directional risk. The vehicle exterior detection unit 121 may also perform risk analysis at predetermined intervals and add up risk points. The vehicle exterior detection unit 121 may also estimate the behavior of a moving object from fluctuations in the risk points, and detect the approach of a moving object to the vehicle when it is estimated that a predetermined behavior has been performed.

[0041] In this way, the monitoring device 100 detects a moving object outside the vehicle through risk analysis using the position and direction, and can detect the moving object after evaluating the object according to its movement, such as passing by, looking into the vehicle, or intruding into the vehicle. In other words, the monitoring device 100 can prevent false detections and reduce unnecessary alarms and notifications.

[0042] 4, the outside-of-vehicle detection unit 121 distinguishes between movement and stay using position information. For example, the outside-of-vehicle detection unit 121 distinguishes between movement and stay based on whether the movement distance in a predetermined period is equal to or less than a threshold. For example, the outside-of-vehicle detection unit 121 determines that the user is staying if the movement distance in X seconds is less than a radius R.

[0043] [Notification Process] Next, a notification to the outside of the vehicle performed by the monitoring device 100 will be described with reference to FIG. 5 . When the inside-vehicle detection unit 122 detects a moving object inside the vehicle without the outside-vehicle detection unit 121 detecting a person approaching the vehicle, the notification unit 124 sends a second notification to the outside of the vehicle. At this time, as shown in FIG. 5 , the notification unit 124 may notify the user terminal of the detected information, the response taken by the monitoring device 100, and an image. For example, the notification unit 124 notifies the user terminal of the message "A moving object was detected inside the vehicle without detecting any abnormality. It was determined that there was a waiting person, and the system was turned off," along with the date and time information "2022 / 08 / 01 14:35," the detection type "waiting person," and the target image.

[0044] [Flowchart] Next, the processing performed by the monitoring device 100 configured as described above will be described with reference to the flowchart in Fig. 6. The flowchart in Fig. 6 is mainly executed by the control unit 120. This flowchart can also be configured as a program executed by the CPU of the control unit 120 to form a monitoring program. Note that steps S101 to S106 below can also be executed in a different order. Also, some of the processing of steps S101 to S106 below may be omitted.

[0045] First, the notification unit 124 determines whether or not a moving object outside the vehicle has been detected by the vehicle exterior detection unit 121 (step S101). If the notification unit 124 determines that a moving object outside the vehicle has been detected by the vehicle exterior detection unit 121 (step S101 "YES"), the notification unit 124 subsequently determines whether or not a moving object inside the vehicle has been detected by the vehicle interior detection unit 122 (step S102).

[0046] Here, if the notification unit 124 determines that the in-vehicle detection unit 122 has detected a moving object inside the vehicle (step S102 "YES"), the notification unit 124 notifies the outside of the vehicle of the first notification and the second notification (step S103).

[0047] On the other hand, returning to step S102, if the notification unit 124 determines that the in-vehicle detection unit 122 has not detected a moving object inside the vehicle (step S102 "NO"), the notification unit 124 sends a first notification to the outside of the vehicle (step S104).

[0048] On the other hand, returning to step S101, if the notification unit 124 determines that the outside vehicle detection unit 121 has not detected a moving object outside the vehicle (step S101 "NO"), the notification unit 124 then determines whether the inside vehicle detection unit 122 has detected a moving object inside the vehicle (step S105).

[0049] Here, if the notification unit 124 determines that the interior detection unit 122 has detected a moving object inside the vehicle (step S105 "YES"), the notification unit 124 notifies the outside of the vehicle of a second notification (step S106).

[0050] On the other hand, returning to step S105, if the notification unit 124 determines that the in-vehicle detection unit 122 has not detected a moving object inside the vehicle (step S105 "NO"), the notification unit 124 does not issue either the first notification or the second notification.

[0051] [Effect] The monitoring device 100 according to the embodiment has an outside-vehicle detection unit 121 that detects moving objects outside the vehicle, an inside-vehicle detection unit 122 that detects moving objects inside the vehicle, and a notification unit 124 that, when the outside-vehicle detection unit 121 detects a moving object approaching the vehicle and the inside-vehicle detection unit 122 detects a moving object inside the vehicle, sends a first notification and a second notification to the outside of the vehicle.

[0052] As a result, the monitoring device 100 can use detection information of moving objects outside the vehicle and detection information of moving objects inside the vehicle to send multiple types of notifications to the outside of the vehicle, thereby providing appropriate notifications according to the situation inside and outside the vehicle.

[0053] In addition, in the monitoring device 100 according to the embodiment, the outside-of-vehicle detection unit 121 detects the approach of a moving object to the vehicle using information on the position and direction.

[0054] This allows the monitoring device 100 to detect moving objects outside the vehicle using position and direction information, preventing false detection of moving objects outside the vehicle, while also providing appropriate notifications depending on the situation inside and outside the vehicle.

[0055] Furthermore, in the monitoring device 100 according to the embodiment, the notification unit 124 issues an audible alarm as the first notification, and sends a notification to the user terminal as the second notification.

[0056] As a result, the monitoring device 100 can issue an alert for situations outside the vehicle that pose a high risk, and notify the user terminal for situations inside the vehicle that require notification, thereby providing appropriate notifications depending on the situation inside and outside the vehicle.

[0057] In addition, in the monitoring device 100 according to the embodiment, if the outside vehicle detection unit 121 does not detect the approach of a moving object to the vehicle, and the inside vehicle detection unit 122 detects a predetermined state inside the vehicle, the notification unit 124 sends a second notification to the outside of the vehicle.

[0058] As a result, the monitoring device 100 does not issue an alarm when an alarm is not necessary, and issues a notification when a specified state inside the vehicle is detected, thereby allowing the monitoring device 100 to provide appropriate notifications depending on the situation inside and outside the vehicle.

[0059] In addition, in the monitoring device 100 according to the embodiment, if the outside vehicle detection unit 121 does not detect the approach of a moving object to the vehicle, but the inside vehicle detection unit 122 detects a moving object inside the vehicle, the notification unit 124 sends a second notification to the outside of the vehicle.

[0060] This allows the monitoring device 100 to not issue an alarm when an alarm is not necessary, and to issue a notification when a moving object is detected inside the vehicle, thereby allowing the monitoring device 100 to issue an appropriate notification depending on the situation inside and outside the vehicle.

[0061] In addition, the monitoring device 100 according to the embodiment further includes an acquisition unit 123 that acquires the temperature inside the vehicle, and the notification unit 124 does not detect the approach of a moving object to the vehicle using the outside vehicle detection unit 121, but detects a moving object inside the vehicle using the inside vehicle detection unit 122, and if the temperature inside the vehicle acquired by the acquisition unit 123 exceeds a threshold value, it sends a second notification to the outside of the vehicle.

[0062] As a result, the monitoring device 100 does not issue an alarm when an alarm is not necessary, detects moving objects inside the vehicle, and issues a notification when the temperature inside the vehicle exceeds a threshold, thereby preventing accidents in which people are left inside the vehicle and providing appropriate notifications depending on the situation inside and outside the vehicle.

[0063] In addition, the monitoring device 100 according to the embodiment further includes an acquisition unit 123 that acquires audio from inside the vehicle, and the notification unit 124 sends a second notification to the outside of the vehicle when the outside vehicle detection unit 121 does not detect the approach of a moving object to the vehicle and the volume of the audio from inside the vehicle acquired by the acquisition unit 123 exceeds a threshold value.

[0064] As a result, the monitoring device 100 does not issue an alarm when an alarm is unnecessary, and issues a notification when the volume of the voice inside the vehicle exceeds a threshold, thereby preventing accidents in which people are left inside the vehicle and providing appropriate notifications depending on the situation inside and outside the vehicle.

[0065] In addition, in the monitoring device 100 according to the embodiment, if the outside vehicle detection unit 121 does not detect the approach of a moving object to the vehicle, and the inside vehicle detection unit 122 detects the movement of a moving object inside the vehicle toward the driver's seat, the notification unit 124 sends a second notification to the outside of the vehicle.

[0066] As a result, the monitoring device 100 does not issue an alarm when an alarm is not necessary, and by notifying the driver when a moving object inside the vehicle moves toward the driver's seat, the monitoring device 100 can warn against accidental erroneous operation by waiting persons, etc., and can provide appropriate notifications depending on the situation inside and outside the vehicle.

[0067] In addition, in the monitoring device 100 according to the embodiment, if the outside vehicle detection unit 121 does not detect the approach of a moving object to the vehicle, and the inside vehicle detection unit 122 detects the operation of an inside vehicle device, the notification unit 124 sends a second notification to the outside of the vehicle.

[0068] As a result, the monitoring device 100 does not issue an alarm in situations where an alarm is not necessary, and by issuing a notification when it detects operation of an in-vehicle device, it is possible to prevent waiting persons, etc. from operating vehicle devices and to issue appropriate notifications depending on the situation inside and outside the vehicle.

[0069] [Hardware Configuration] The monitoring device 100 according to the embodiment described above is realized, for example, by a computer 1000 configured as shown in Fig. 7. Fig. 7 is a hardware configuration diagram showing an example of a computer that realizes the functions of the monitoring device 100. The computer 1000 has a CPU 1100, a RAM 1200, a ROM 1300, a HDD 1400, a communication interface (I / F) 1500, an input / output interface (I / F) 1600, and a media interface (I / F) 1700.

[0070] The CPU 1100 operates and controls each unit based on programs stored in the ROM 1300 or the HDD 1400. The ROM 1300 stores a boot program executed by the CPU 1100 when the computer 1000 starts up, programs that depend on the hardware of the computer 1000, and the like.

[0071] The HDD 1400 stores programs executed by the CPU 1100 and data used by the programs. The communication interface 1500 receives data from other devices via a predetermined communication network and sends the data to the CPU 1100, and transmits data generated by the CPU 1100 to other devices via the predetermined communication network.

[0072] The CPU 1100 controls output devices such as a display and a printer, and input devices such as a keyboard and a mouse, via the input / output interface 1600. The CPU 1100 acquires data from the input devices via the input / output interface 1600. The CPU 1100 also outputs generated data to the output devices via the input / output interface 1600.

[0073] Media interface 1700 reads a program or data stored in recording medium 1800 and provides it to CPU 1100 via RAM 1200. CPU 1100 loads the program or data from recording medium 1800 onto RAM 1200 via media interface 1700 and executes the loaded program. Recording medium 1800 is, for example, an optical recording medium such as a DVD (Digital Versatile Disc) or a PD (Phase Change Rewritable Disc), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory.

[0074] For example, when the computer 1000 functions as the monitoring device 100 according to the embodiment, the CPU 1100 of the computer 1000 executes programs loaded onto the RAM 1200 to realize the functions of the control unit 120. The CPU 1100 of the computer 1000 reads and executes these programs from the recording medium 1800, but as another example, the CPU 1100 may obtain these programs from another device via a predetermined communication network.

[0075] [Others] Although one example of an embodiment of the present invention has been described above, the present invention is not limited to the above example. In other words, a person skilled in the art can implement various modifications in accordance with conventionally known knowledge without departing from the gist of the present invention. As long as such modifications still include the monitoring device of the present invention, they are of course included in the scope of the present invention.
