Description

[Technical Field]

[0001] The present invention relates to a security fee determination system and method. [Background technology]

[0002] A well-known home security system involves placing various security sensors inside the house and automatically notifying a security center via a communication device inside the house if it detects an anomaly, such as an intruder entering the house. Such systems monitor homes 24 hours a day, 365 days a year, and security guards are stationed at the security center. Therefore, it is common for a security fee to be charged for using such a system. [Overview of the project] [Problems that the invention aims to solve]

[0003] The probability of a home security system detecting an anomaly and requiring action from the security center or security guards likely differs between households that regularly lock their doors and have a high level of security awareness and those that do not. Despite this, traditional security fees have not differentiated significantly between these two types of households.

[0004] The present invention has been made in view of the above problems, and aims to provide a security fee determination system that can improve each household's security awareness or security actions by differentiating the fees for home security based on differences in security awareness or security actions. [Means for solving the problem]

[0005] To solve the above problems, the security fee determination system according to the present invention includes a sensor that detects the open / closed state or locked state of at least one of the windows or exterior doors provided in a house; a security level determination means that determines the security level of the house based on the detection result of the sensor; and a security fee determination means that determines the fee for security of the house based on the determined security level.

[0006] Here, the sensor may detect the open / closed state of at least one of the window or the exterior door. The security level determining means may determine the security level of the house based on the time during which at least one of the window or the exterior door is open in a unit period.

[0007] Further, the sensor may detect the locked state of at least one of the window or the exterior door. The security level determining means may determine the security level of the house based at least on the time during which the window or the exterior door is unlocked in a unit period.

[0008] Further, the system may further include presence determining means for determining whether a resident is present in the house. The security level determining means may determine the security level of the house further based on whether a resident is present in the house while at least one of the window or the exterior door is open.

[0009] Further, the security level determining means may determine the security level of the house further based on whether a resident is present in the house while at least one of the window or the exterior door is unlocked.

[0010] Further, the system may further include temperature and humidity acquiring means for acquiring at least one of the temperature or humidity outside the house. The security level determining means may determine the security level of the house based on the temperature or humidity outside the house while the window is open.

[0011] Further, the security fee determining method according to the present invention includes a step of detecting, by a sensor, the open / closed state or locked state of at least one of a window or an exterior door provided in a house, a step of determining the security level of the house based on the detection result of the sensor, and a step of determining a fee related to security of the house based on the determined security level. Effects of the Invention

[0012] According to the present invention, it is possible to differentiate the fees for home security based on differences in crime prevention awareness, thereby improving crime prevention awareness or crime prevention behavior in each household. [Brief explanation of the drawing]

[0014] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0015] Figure 1 is an overall configuration diagram of a security fee determination system according to an embodiment of the present invention. As shown in the figure, the security fee determination system 10 according to this embodiment consists of a plurality of sensors placed inside and outside a residence (including apartment buildings and other multi-unit dwellings) 20, a home server 30 that aggregates information from these sensors, a management server 50, a payment server 60, and a residential security server 70. The home server 30, management server 50, payment server 60, and residential security server 70 are, for example, computers, and are all connected to a communication network 40 such as the Internet, and are able to communicate data with each other.

[0016] The house 20 is equipped with a window 21 and an entrance door 22. The window 21 is fitted with a window open / close sensor 32 to detect its open / closed state and a window lock sensor 33 to detect its locked state. The entrance door 22 is also fitted with a door open / close sensor 36 to detect its open / closed state and a door lock sensor 35 to detect its locked state.

[0017] Inside the house 20, an occupancy sensor 34 is installed to detect the presence or absence of residents using cameras, motion sensors, microphones, etc. Outside the house 20, an outdoor temperature and humidity sensor 31 is installed to detect the outside temperature and humidity. The home server 30 acquires detection signals from these sensors 31-36 in real time and obtains information such as the outside temperature and humidity, the open / closed and locked status of the windows 21 and the front door 22, and whether or not there are people inside the house. Based on the information thus acquired, it generates daily locking data. The daily locking data indicates the level of crime prevention awareness or crime prevention behavior of the residents of the house 20 on a daily basis. The home server 30 transmits this daily locking data to the management server 50. It also displays the daily locking data on a display 37 installed inside the house 20. Furthermore, the daily locking data may be transmitted to a smartphone or other mobile device owned by the residents of the house 20 (not shown), and the daily locking data may be displayed on such a mobile device. This allows residents to check their daily locking data, thereby increasing their awareness of crime prevention and improving their crime prevention behavior.

[0018] The management server 50 calculates the security level of the house 20 based on daily locking data for a certain period (e.g., one month) transmitted from the home server 30, and determines the security fee corresponding to the security level. The determined security fee information is notified to the settlement server 60, and the settlement process for that fee is carried out. The security fee can be any fee related to security, such as the dispatch fee for security guards or the usage fee for security-related systems. Any of these fees can be calculated according to the security level. The security level is also transmitted to the home server 30 and displayed on the display 37. The security level, like the daily locking data, may also be transmitted to the resident's mobile device.

[0019] The residential security server 70 receives notifications from the home server 30 when suspicious intrusions or anomalies are detected in the house 20, and informs security guards of these occurrences. For example, it is installed in a residential security company.

[0020] According to this embodiment, the home server 30 and the management server 50 work together to determine the security level of the residents of the house 20 and to determine the security fee according to the determined security level. This makes it possible to lower the security fee for residents with a higher level of security awareness, thereby encouraging residents to improve their security awareness. In addition, daily locking data and security levels are displayed on the display 37 or transmitted to the residents' mobile devices to notify them. This helps to encourage residents to lock their doors.

[0021] Figure 2 is a functional block diagram of the home server 30. As shown in the figure, the home server 30 functionally includes a temperature and humidity storage unit 30a, an occupancy information storage unit 30b, a window opening time calculation unit 30c, a window unlocking time calculation unit 30d, a front door opening time calculation unit 30e, a front door unlocking time calculation unit 30f, and a data transmission unit 30g. These functions are realized by the execution of a predetermined program on the home server 30, which is a computer. This program may be stored in various computer-readable storage media and installed from there to the home server 30. Alternatively, it may be downloaded from another computer connected to the communication network 40.

[0022] The temperature and humidity storage unit 30a stores the temperature and humidity of the outside air obtained from the outside temperature and humidity sensor 31 in chronological order. The occupancy information storage unit 30b stores information regarding the presence or absence of residents, i.e., occupancy information, obtained from the occupancy sensor 34, in chronological order.

[0023] The window open time calculation unit 30c calculates the time the window 21 is open in a day (unit period), i.e., the window open time, based on the detection signal from the window open / close sensor 32, and determines the window open time level based on that window open time. The window unlock time calculation unit 30d calculates the time the window 21 is not locked in a day, i.e., the window unlock time, based on the locking information from the window lock sensor 33, and determines the window unlock level based on that window unlock time. The front door open time calculation unit 30e calculates the time the front door 22 is open, i.e., the front door open time, from the detection result of the front door open / close sensor 36, and calculates the front door open time level based on that front door open time. Furthermore, the front door unlock time calculation unit 30f calculates the time the front door 22 is not locked, i.e., the front door unlock time, based on the detection result of the front door lock sensor 35, and determines the front door unlock time level based on that front door unlock time.

[0024] Each of these levels is an important indicator showing the daily security awareness and actions of the home 20, and is generated within the home server 30. The data transmission unit 30g constructs daily locking data using the window open time level, window unlocking time level, front door open time level, and front door unlocking time level, and transmits this daily locking data to the management server 50.

[0025] Figure 3 is a functional block diagram of the management server 50. As shown in the figure, the management server 50 functionally includes a daily data storage unit 50a, a security level determination unit 50b, a security level output unit 50c, and a security fee determination unit 50d. These functions are realized by the execution of a predetermined program on the management server 50, which is a computer. This program may be stored in various computer-readable storage media and installed on the management server 50 from there. Alternatively, it may be downloaded from another computer connected to the communication network 40.

[0026] The daily data storage unit 50a stores the daily locking data transmitted from the home server 30. Specifically, as shown in Figure 4, the window open time level, window unlocked time level, front door open time level, and front door unlocked time level are stored for a month at a time for each day. These levels are represented by values ​​from 1 to 10, for example, with higher numbers indicating longer periods of time when the windows 21 or front door 22 are left open or unlocked. Based on this accumulation of daily data, the management server 50 calculates the security level of the house 20 using the security level determination unit 50b. Specifically, the average or weighted average of each level related to the windows 21 and front door 22 is calculated, and the final security level is derived by subtracting this value from 11. This security level falls within the range of 1 to 10, with higher numbers indicating better locking conditions. The calculated security level is notified to the home server 30 by the security level output unit 50c and presented to the resident via the display 37. Alternatively, it can be sent to the mobile devices of residents who have registered in advance and presented to them.

[0027] The security fee determination unit 50d performs fee determination processing so that the security fee is set lower for houses 20 with a higher level of security. This ensures that the increased security awareness of residents of houses 20 is reflected in the fees. The timing of security fee updates can be set arbitrarily; for example, new security fees can be applied monthly or every few months.

[0028] Figure 5 is a flowchart showing the processing of the window opening time calculation unit 30c. As shown in the figure, the window opening time calculation unit 30c first checks the signal from the window opening / closing sensor 32 to determine whether the window 21 has been opened or not (S501). If it has not been opened, it checks whether the current time has reached a reference time set at the end of the day (such as a specific time in the middle of the night or early morning) (S502). If the reference time has not been reached, it returns to S501. On the other hand, if the reference time has been reached, it terminates the processing for the day.

[0029] On the other hand, if it is determined in S501 that the window 21 has been opened, the current time at that point is stored (S503), and then it is monitored whether the window 21 has been closed again, or whether the current time has reached a reference time (S504). When either of these occurs, the time during which the window 21 was open, that is, the time from the time stored in S503 to the current time, is calculated, and this time is denoted as t WO is acquired (S505).

[0030] Next, with reference to the presence / absence information storage unit 30b, it is determined whether a resident was inside the house during the time t WO (S506). If even a small amount of absence time is included during the time t WO , or if a certain proportion or more of the time t WO is absence, it may be treated that no resident was present. If it is determined that no resident was present, the process proceeds to S509. On the other hand, if it is determined that a resident was present, it is determined whether the outside air temperature and humidity stored in the temperature and humidity storage unit 30a satisfy predetermined comfortable temperature and humidity conditions (for example, an air temperature of 20°C to 35°C and a humidity of less than 70%) (S507). When the comfortable temperature and humidity conditions are satisfied, it is regarded that the window 21 was opened with the intention of taking in comfortable outside air, and the time t calculated in S505 WO multiplied by a coefficient k (0≦k<1) is added to the existing window opening time T WO , whereby the window opening time T WO is updated (S508). Here, the value of the coefficient k may be appropriately set within a range of 0 or more and less than 1. In this way, when a resident is present, by using the actual window opening time t WO multiplied by the coefficient k of 0 or more and less than 1, an increase in the window opening time T WO can be suppressed. Thereby, when a resident is present, even if the window 21 is open, the security level can be prevented from becoming lower than when no resident is present, and the resident's security awareness and security behavior can be appropriately evaluated.

[0031] On the other hand, when it is determined that the comfortable temperature and humidity conditions are not satisfied (S507) or when it is determined that the resident is absent (S506), the time t WO is directly used as the existing window opening time T WOAdd to the window opening time T WO Update (S509). Note that in S508, the time t was actually open of window 21. WO Using a smaller value (the value multiplied by the coefficient k) for the window opening time T WO By suppressing the increment of time t, WO In this system, it is possible to appropriately generate daily locking data and security levels, taking into account cases where the resident is inside the house 20 or where the window 21 is presumably opened to let in comfortable outside air.

[0032] In S510, the reference time and the current time are compared. If the reference time has not yet passed, the process returns to S501 and monitors the open / closed status of window 21 again. If the reference time has passed, the processing for the day is terminated. After the processing is complete, the window opening time T, which was finally determined in this way, is used. WO Based on this value, the window open time level is determined by comparing it with several pre-set ranges. A higher window open time level indicates that the windows were left open for a longer period of time that day. This level information is sent from the home server 30 to the management server 50 as part of the daily locking data and is used to determine the security level and security fees.

[0033] Figure 6 is a flowchart showing the processing of the window unlocking time calculation unit 30d. As shown in the figure, the window unlocking time calculation unit 30d first checks the signal from the window lock sensor 33 to determine whether the window 21 has been unlocked (S601). If it has not been unlocked, it checks whether the current time has reached the reference time (S602). If the reference time has not been reached, it returns to S601. On the other hand, if the reference time has been reached, it terminates the processing for the day.

[0034] On the other hand, if it is determined in S601 that window 21 has been unlocked, the current time at that time is stored (S603), and then it is monitored whether window 21 has been locked again or whether the current time has reached the reference time (S604). If either of these occurs, the time during which window 21 was unlocked, i.e., the time from the time stored in S603 to the current time is calculated, and that time is t WL It is acquired as (S605).

[0035] Next, refer to the presence / absence information storage unit 30b, time t WL It is determined whether the resident was inside the dwelling 20 during time t (S606). WL If there was even a short period of absence during that time, or if the time t WL If a certain percentage or more of the residents are absent, it may be treated as if there were no residents. If it is determined that there were no residents, the time t WL Existing window unlocking time T WL Add the window unlocking time T to this. WL Update (S608).

[0036] On the other hand, in S606, time t WL If it is determined that the resident was inside the house 20 during that time, proceed to S607, and the time t calculated in S605 WL The value obtained by multiplying this by a coefficient k (0 ≤ k < 1) is the existing window unlocking time T. WL This is added to the window unlocking time T. WL Update the following. The value of the coefficient k can be set appropriately within the range of 0 or greater and less than 1. The actual time t when window 21 was unlocked. WL Using a value smaller than (the value multiplied by the coefficient k) for the window unlocking time T WL By suppressing the increment of time t, WL Considering that the resident was inside the house 20, daily locking data and security levels can be appropriately generated.

[0037] In S609, the reference time is compared with the current time. If the reference time has not yet passed, the process returns to S601 and monitors whether window 21 will be unlocked again. If the reference time has passed, the processing for the day is terminated. After the processing is complete, the window unlock time T, which was finally determined in this way, is calculated. WL Based on this value, the window unlocking time level is determined by comparing it with several pre-set ranges. A higher window unlocking time level indicates that the window was left unlocked for a longer period of time that day. This level information is also sent from the home server 30 to the management server 50 as part of the daily locking data and is used to determine the security level and security fees.

[0038] Figure 7 is a flowchart showing the processing of the front door open time calculation unit 30e. As shown in the figure, the front door open time calculation unit 30e first refers to the signal from the front door open / close sensor 36 to determine whether the front door 22 has been opened or not (S701). If it has not been opened, it determines whether the current time has reached the reference time (S702). If the reference time has not been reached, it returns to S701. On the other hand, if the reference time has been reached, it terminates the processing for the day.

[0039] On the other hand, if it is determined in S701 that the front door 22 has been opened, the current time at that time is stored (S703), and then it is monitored whether the front door 22 has been closed again or whether the current time has reached the reference time (S704). If either of these occurs, the time the front door 22 was open, that is, the time from the time stored in S703 to the current time is calculated, and that time is t DO Acquired as (S705).

[0040] Next, refer to the presence / absence information storage unit 30b, time t DO During this time, check whether the resident was inside the house 20. DO If there was even a short period of absence during that time, or if the time t DO If a certain percentage or more of the residents are absent, it may be treated as if there were no residents. If it is determined that there were no residents, the time t DO The existing front door opening time T DO Add the front door opening time T DO Update (S708).

[0041] On the other hand, in S706, time t DO If it is determined that the resident was inside the house 20 during that time, the time t calculated in S705 DO The value obtained by multiplying this by a coefficient k (0 ≤ k < 1) is the existing front door opening time T. DO This is added to the front door opening time T. DO Update (S707). The value of the coefficient k may be set appropriately within the range of 0 or more and less than 1. The time t during which the front door 22 was actually open.DO Using a value smaller than (the value multiplied by the coefficient k) the front door opening time T DO By suppressing the increment of time t, DO Considering that the resident was inside the house 20, daily locking data and security levels can be appropriately generated.

[0042] After that, the reference time and the current time are compared (S709), and if it is not yet the reference time, the process returns to S701 and monitors again whether the front door 22 has been opened. If the reference time has passed, the processing for the day is terminated. After the processing is completed, the front door opening time T, which was finally determined in this way, is... DO Based on this value, the front door open time level is determined by comparing it with several pre-set ranges. A higher front door open time level indicates that the front door was left open for a longer period of time that day. This level information is also sent from the home server 30 to the management server 50 as part of the daily locking data and is used to calculate the security level and set security fees.

[0043] Figure 8 is a flowchart showing the processing of the front door unlocking time calculation unit 30f. As shown in the figure, the front door unlocking time calculation unit 30f first checks the signal from the front door lock sensor 35 to determine whether the front door 22 has been unlocked (S801). If it has not been unlocked, it checks whether the current time has reached the reference time (S802). If the reference time has not been reached, it returns to S801. On the other hand, if the reference time has been reached, it terminates the processing for the day.

[0044] On the other hand, if it is determined in S801 that the front door 22 has been unlocked, the current time at that time is stored (S803), and then it is monitored whether the front door 22 has been locked again or whether the current time has reached the reference time (S804). If either of these occurs, the time the front door 22 was unlocked, that is, the time from the time stored in S803 to the current time is calculated, and that time is t DL It is acquired as (S805).

[0045] Next, refer to the presence / absence information storage unit 30b, time t DL It is determined whether the resident was inside the dwelling 20 during time t (S806). DL If there was even a short period of absence during that time, or if the time t DL If a certain percentage or more of the residents are absent, it may be treated as if there were no residents. If there were no residents, the time t DL The existing front door unlocking time T DL Add the front door unlocking time T DL Update (S808).

[0046] On the other hand, in S806, time t DL If it is determined that the resident was inside the dwelling 20 during that time, the time t calculated in S805 DL The value obtained by multiplying this by a coefficient k (0 ≤ k < 1) is the existing front door unlocking time T. DL This is added to the front door unlocking time T. DL Update (S807). The value of coefficient k may be set appropriately within the range of 0 or more and less than 1. The actual time t when the front door 22 was unlocked. DL Using a value smaller than (the value multiplied by the coefficient k) the front door unlocking time T DL By suppressing the increment of time t, DL Considering that residents are inside the residence 20, daily locking data and security levels can be appropriately generated.

[0047] After that, the reference time and the current time are compared (S809), and if it is not yet the reference time, the process returns to S801 and monitors again whether the front door 22 is unlocked. If the reference time has passed, the processing for the day is terminated. After the processing is completed, the front door unlocking time T, which was finally determined in this way, is calculated. DL Based on this value, the front door unlocking time level is determined by comparing it with several pre-set ranges. A higher front door unlocking time level indicates that the front door was left unlocked for a longer period of time that day. This level information is also sent from the home server 30 to the management server 50 as part of the daily locking data and is reflected in the calculation of the security level and the setting of security fees.

[0048] As explained above, the security fee determination system 10 according to this embodiment measures the opening and closing times and unlocking times of windows 21 and entrance doors 22, and aggregates them as daily locking data. At this time, information on the presence or absence of residents and information on outside temperature and humidity are also taken into consideration, and the opening time of windows and entrance doors is evaluated as shorter if there is a reasonable reason, such as to let in comfortable outside air. As a result, the penalty in time calculation is reduced for opening or unlocking windows 21 and entrance doors 22 when there is a reasonable reason, while conversely, if windows 21 and entrance doors 22 are left open despite the resident being absent or the outside temperature and humidity being uncomfortably bad, the opening time and unlocking time are added as is, accurately reflecting actual security awareness and actions. The daily locking data thus obtained is transmitted to the management server 50, and the security level is determined by comprehensively considering the levels of opening time and unlocking time of windows 21 and entrance doors 22. Therefore, households that diligently lock their doors will have a higher security level and lower security fees. This system encourages users to be more mindful of the importance of locking their doors and windows on a daily basis, resulting in a significant reduction in the risk of burglary and improved home security. Furthermore, security levels and daily locking data are presented to residents in real time via displays and mobile devices, allowing them to reflect on their daily locking habits and consider the balance with security costs. This is expected to lead to increased security awareness and behavior in the long term, as well as improved efficiency in security operations.

[0049] It should be noted that the present invention is not limited to the above embodiments, and various modifications are also included in the present invention. For example, instead of the outside temperature and humidity sensor 31, the temperature and humidity of the outside air of the house 20 may be obtained from local weather information via the communication network 40. Alternatively, only one of temperature or humidity may be considered.

[0050] Furthermore, in the above embodiment, the presence or absence of residents was determined by the detection signal of the presence / absence sensor, but the presence or absence may also be determined from the operating status of air conditioning equipment, lighting equipment, changes in temperature and humidity sensors, etc.

[0051] Furthermore, in the above embodiment, the home server 30 and the management server 50 shared the processing for determining the security level and security fees, but the manner of sharing is not limited to the above. Also, either the home server 30 or the management server 50 may perform all the processing alone.

[0052] Furthermore, in the above embodiment, the security level was determined by comprehensively considering the levels of open time and unlocking time of multiple windows 21 and entrance doors 22. However, the security level may also be calculated based on daily locking data for only specific windows 21 or entrance doors 22.

[0053] Furthermore, in the above embodiment, the security level for each day was calculated using daily door locking data. However, the security levels for window open time, window unlocking time, front door open time, and front door unlocking time may also be calculated from one month's worth of daily door locking data.

[0054] Furthermore, in the above embodiment, the security level was represented by a predetermined numerical value from 1 to 10, but the security level may also be determined by assigning a "○" if the value is greater than a preset threshold (for example, 7). In addition, the security level may be determined by summing the number of "○"s for each security level: window open time level, window unlocked time level, front door open time level, and front door unlocked time level.

[0055] Furthermore, when determining the security level, it is not always necessary to consider the open / closed state of windows, the locked state of windows, the open / closed state of exterior doors, and the locked state of exterior doors; it is acceptable to determine the security level by considering only some of these factors.

[0056] Furthermore, by subtracting the window opening time from the window unlocking time, one can obtain the time when the window is closed but unlocked, and this can be used to determine the level of security. Similarly, by subtracting the external door unlocking time from the external door unlocking time, one can obtain the time when the external door is closed but unlocked, and this can be used to determine the level of security.
