Security level output system and method

[0001] This invention relates to a security level output system and method.

[0002] Smart homes, which connect residential equipment and household appliances to the internet to improve the comfort of the home, are attracting attention. Home security systems, which use various security sensors placed inside the house to detect anomalies such as intruders entering the home, are also well known.

[0003] In order to continue living safely and comfortably, it is essential that residents have sufficient crime prevention awareness or take appropriate crime prevention actions. However, until now, there has been no system in place to encourage residents to improve their crime prevention awareness or crime prevention actions.

[0004] The present invention has been made in view of the above problems, and aims to provide a security level output system that can notify residents of the security level of their home, thereby encouraging residents to improve their security awareness or security behavior.

[0011] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0012] Figure 1 is an overall configuration diagram of a security level output system according to an embodiment of the present invention. As shown in the figure, the security level output system 10 according to this embodiment consists of a plurality of sensors placed inside and outside a house (including apartment buildings and other multi-unit dwellings) 20, a home server 30 that aggregates information from these sensors, and a management server 50. The home server 30 and the management server 50 are, for example, computers, and both are connected to a communication network 40 such as the Internet, and are able to communicate data with each other.

[0013] The house 20 is equipped with windows 21 and an entrance door (exterior door) 22. The windows 21 are fitted with a window open / close sensor 32 to detect the open / closed state and a window lock sensor 33 to detect the locked state. The entrance door 22 is also fitted with a door open / close sensor 36 to detect the open / closed state and a door lock sensor 35 to detect the locked state.

[0014] Inside the residence 20, an occupancy sensor 34 that detects whether a resident is present or absent via a camera, human motion sensor, microphone, or the like is provided. Outside the residence 20, an outdoor air temperature and humidity sensor 31 that detects the temperature and humidity of outdoor air is provided. The home server 30 acquires detection signals from these sensors 31 to 36 in real time, and obtains information such as the temperature and humidity of outdoor air, the open / closed and locked states of the window 21 and the entrance door 22, and occupancy information indicating whether there is a person indoors or not. Then, daily lock-up data is generated based on the information thus acquired. The daily lock-up data indicates the level of the resident's crime prevention awareness or crime prevention behavior of the residence 20 for each day. The home server 30 transmits this daily lock-up data to the management server 50. In addition, the daily lock-up data is displayed on a display 37 installed in the residence 20. Furthermore, the daily lock-up data may be transmitted to a smartphone or other portable device owned by the resident of the residence 20 (not shown), and the daily lock-up data may be displayed on such a portable device. This allows the resident to raise their own crime prevention awareness and improve their crime prevention behavior while checking the daily lock-up data.

[0015] The management server 50 calculates the crime prevention level of the residence 20 based on the daily lock-up data for a fixed period (for example, one month) transmitted from the home server 30. The crime prevention level is transmitted to the home server 30 and displayed on the display 37. Similar to the daily lock-up data, the crime prevention level may also be transmitted to the resident's portable device.

[0016] According to the present embodiment, the daily lock-up data and the crime prevention level are displayed on the display 37 or transmitted to the resident's portable device to notify the resident. This can prompt the resident to lock up the residence.

[0017] Fig. 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 status information storage unit 30b, a window open time calculation unit 30c, a window unlocked time calculation unit 30d, an entrance door open time calculation unit 30e, an entrance door unlocked time calculation unit 30f, and a data transmission unit 30g. These functions are realized by executing 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 to the home server 30 from such media. Alternatively, the program may be downloaded from another computer connected to the communication network 40.

[0018] The temperature and humidity storage unit 30a stores the temperature and humidity of outside air acquired from the outside air temperature and humidity sensor 31 in time series. The occupancy status information storage unit 30b stores information relating to whether a resident is at home or not acquired from the occupancy sensor 34, that is, occupancy status information, in time series.

[0019] The window open time calculation unit 30c calculates a time during which the window 21 is open in one day (a unit period), that is, a window open time, based on a detection signal from the window open / close sensor 32, and determines a window open time level based on the window open time. The window unlocked time calculation unit 30d calculates a time during which the window 21 is not locked in one day, that is, a window unlocked time, based on locking information from the window lock sensor 33, and determines a window unlocked level based on the window unlocked time. The entrance door open time calculation unit 30e calculates a time during which the entrance door 22 is open, that is, an entrance door open time, from a detection result of the entrance door open / close sensor 36, and calculates an entrance door open time level based on the entrance door open time. Further, the entrance door unlocked time calculation unit 30f calculates a time during which the entrance door 22 is not locked, that is, an entrance door unlocked time, based on a detection result of the entrance door lock sensor 35, and determines an entrance door unlocked time level based on the entrance door unlocked time.

[0020] 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.

[0021] 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, and a security level output unit 50c. 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.

[0022] 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 and 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 displayed 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.

[0023] FIG. 5 is a flowchart showing processing by the window opening time calculation unit 30c. As shown in this figure, the window opening time calculation unit 30c first refers to a signal from the window opening / closing sensor 32 to determine whether the window 21 has been opened (S501). If the window has not been opened, it is checked whether the current time has reached a reference time set at the end of a day (such as a specific time at midnight or early morning) (S502). If the reference time has not been reached, the process returns to S501 again. On the other hand, if the reference time has been reached, the processing for the current day is ended there.

[0024] On the other hand, if it is determined in S501 that the window 21 has been opened, the current time at that time point is stored (S503), and then it is monitored whether the window 21 has been closed again or the current time has reached the reference time (S504). When any of these events 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 t ＷＯ and acquired as such (S505).

[0025] Next, with reference to the presence / absence information storage unit 30b, during the time t ＷＯ it is determined whether the resident was inside the house (S506). If the time t ＷＯ includes even a small amount of absence time, or a certain proportion or more of the time t ＷＯ is an absence period, the case may be treated as no resident being present. If it is determined that no resident was present, the process proceeds to the processing of S509. On the other hand, if it is determined that the resident was present, it is determined whether the outdoor air temperature and humidity stored in the temperature and humidity storage unit 30a satisfy predetermined comfortable temperature and humidity conditions (for example, the temperature is 20°C to 35°C and the humidity is less than 70%) (S507). If the comfortable temperature and humidity conditions are satisfied, it is considered that the window 21 was opened for the purpose of taking in comfortable outdoor air, the value obtained by multiplying the time t calculated in S505 ＷＯ by a coefficient k (0≦k<1) is added to the existing window opening time T ＷＯ , thereby updating the window opening time T ＷＯ (S508). Here, the value of the coefficient k may be appropriately set within the range of 0 or more and less than 1. As described above, when the resident is present, by multiplying the actual window opening time t ＷＯ by the coefficient k of 0 or more and less than 1 for use, the window opening time T ＷＯThis can suppress the increase in [unclear]. As a result, even if the window 21 is open when residents are present, the level of security will not be lower than when no residents are present, and the residents' security awareness and actions can be appropriately evaluated.

[0026] On the other hand, if it is determined that the conditions for comfortable temperature and humidity are not met (S507) or if it is determined that there are no residents (S506), time t ＷＯ Use the existing window opening time T as is. ＷＯ Add 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 presumed to be opened to let in comfortable outside air.

[0027] In S510, the reference time and the current time are compared, and if it is not yet the reference time, the process returns to S501 and the open / closed status of window 21 is monitored again. If the reference time has passed, the processing for the day is terminated. After the processing is completed, 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 open for a longer period of time on that day. This level information is transmitted 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.

[0028] 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 refers to 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.

[0029] On the other hand, if it is determined in S601 that the window 21 has been unlocked, the current time at that time is stored (S603), and then it is monitored whether the 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 the 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).

[0030] Next, refer to the presence / absence information storage unit 30b, time t ＷＬ It is determined whether the resident was inside the house 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 The existing window unlocking time T ＷＬ Add the window unlocking time T to this. ＷＬ Update (S608).

[0031] 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 value of the coefficient k. The value of the coefficient k can be set appropriately within the range of 0 or more 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.

[0032] 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 unlocking time T, which was finally determined in this way, is used. ＷＬBased 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 transmitted from the home server 30 to the management server 50 as part of the daily locking data and is reflected in the determination of the security level.

[0033] 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.

[0034] 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 It is acquired as (S705).

[0035] Next, refer to the presence / absence information storage unit 30b, time t ＷＬ During this time, it is confirmed 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).

[0036] 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 DOThe 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.

[0037] 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 used. 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 transmitted from the home server 30 to the management server 50 as part of the daily locking data and is reflected in the determination of the security level calculation.

[0038] 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 refers to the signal from the front door lock sensor 35 to determine whether or not 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.

[0039] 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).

[0040] Next, refer to the presence / absence information storage unit 30b, time t ＤＬ It is determined whether the resident was inside the house 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).

[0041] On the other hand, in S806, time t ＤＬ If it is determined that the resident was inside the house 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 time T required to unlock the front door. 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.

[0042] 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... 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 transmitted from the home server 30 to the management server 50 as part of the daily locking data and is reflected in the determination of the security level calculation.

[0043] As described above, the security level output 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, so that households that diligently lock their doors will have a higher security level. Daily locking data and security levels are presented to residents in real time via displays and mobile devices, allowing users to review their locking habits on a daily basis. This system encourages users to be more mindful of the importance of locking their doors and windows, ultimately reducing the risk of burglary and contributing to improved home security.

[0044] 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.

[0045] Furthermore, in the above embodiment, the presence or absence of a resident 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. In addition, in the above embodiment, the processing for determining the security level was divided between the home server 30 and the management server 50, but the manner of division is not limited to the above. Moreover, all processing may be performed by either the home server 30 or the management server 50 alone.

[0046] Furthermore, in the above embodiment, the security level was determined by comprehensively considering the open time and unlock time levels 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.
