Description

  The present invention relates to a security system typified by home security, and more particularly to a security system configured to be able to quantitatively evaluate a security risk of a provider that provides a security service. The present invention also relates to a charging fee calculation method for the provider in providing such a security service.

  In recent years, home security services for single-family houses, condominiums, or small-scale stores are becoming widespread. In particular, as a typical service to be provided, when an intrusion from a window or door is detected, a management company that operates the security service is notified of the intrusion. A system that dispatches staff to the provider or contacts the police station or the fire department as necessary.

  In the conventional home security service, the intrusion detection is performed by a monitoring camera, an intrusion detection sensor, or the like arranged at a monitoring target location. At this time, it is difficult for a surveillance camera or sensor to distinguish between intrusion by a suspicious person and entry / exit by a non-suspicious person. It can be switched to a non-security mode that does not require intrusion detection. While the non-security mode is set, the surveillance camera and sensor are turned off. For example, even if a person passes through the sensor detection area, the fact is not recognized by the sensor, and a notification to that effect is sent to the operating company. Also not done.

  In other words, while the non-security mode is set, the security service is not functioning, while the fee structure provided by the operating company that operates the conventional security service is a fixed fee regardless of the functional state of the service. From the standpoint of consumers, there was a sense of being expensive, and this was one factor that prevented security services from spreading.

  Thus, a home security system is disclosed that includes a billing fee calculation means based on a pay-per-use method that generates a fee according to the level of service used (see, for example, Patent Documents 1 and 2).

  According to Patent Document 1, it is possible to provide a pay-per-use system by recording an operation history of an intrusion detection sensor and calculating a fee based on the history. According to Patent Document 2, a plurality of services are provided, and individual charges are set according to the types of each provided service, and the type of service actually used by the customer from the plurality of provided services is managed by the operating company. Therefore, it is possible to provide a pay-as-you-go billing system by charging a fee only for the service actually used.

  According to the methods described in Patent Document 1 and Patent Document 2 described above, the user can enjoy security services at a low price compared to the conventional charging fee system that generates a predetermined fixed fee regardless of the usage form. There is.

  By the way, the users of home security services include, for example, users who are almost at home all day on weekdays, users who frequently go out during the day on weekdays, users who go out during the night on weekdays, and users who go out during the day on holidays. Etc., and there are various lifestyles for each user. On the other hand, it is statistically known that intrusions of suspicious people, especially empty nests, are more frequently committed during the day than at night. Risk) is generally referred to as "security risk"), which is higher in the daytime than at night. Furthermore, the risks for suspicious person intrusion such as empty nests vary depending on the user's residential area and lifestyle, and are not necessarily at the same risk level.

  For this reason, according to the charging method described in Patent Document 1 or Patent Document 2, the service user has the effect of lowering the fee to be paid to the operating company as compared to the conventional fixed fee system. The price is not set considering the risk level. In other words, if the security risk is low, the same price is set despite the low possibility that security services will be dispatched from the security service operator compared to the high security risk. There was unfairness to users.

  The present invention has been made in view of the above problems, and provides a security system capable of quantitatively evaluating security risks in order to set charging charges according to security risks when providing security services. It is intended to do. It is another object of the present invention to provide a charging fee calculation method for providing a security service using a security risk quantitatively evaluated in this way.

  In order to achieve the above object, a security system according to the present invention uses a first storage unit that stores a reference value having a predetermined relationship with a utility usage amount in a monitoring target, and uses the utility usage amount and the reference value. An index value calculation unit that calculates an index value indicating a human activity state in the monitoring target by performing a predetermined calculation; and a risk evaluation unit that evaluates a security risk for the monitoring target based on the index value; The first feature is to include the above.

  In general, a space such as a residence with a high home ratio has a low risk (security risk) against suspicious person intrusion, and a space with a low home ratio has a high security risk. According to the first characteristic configuration of the system of the present invention, the utility usage amount tends to increase as a result of human life activities when the home staying rate is high, the past utility usage amount in the monitoring target, and Processes required for risk assessment because the risk assessment unit performs risk assessment based on index values obtained by performing prescribed calculations using utility usage and reference values that have a prescribed relationship All can be performed only by a predetermined calculation process, and objective risk evaluation becomes possible. As a result, it is possible to perform risk evaluation on the monitoring target by computer processing.

  As the utility, it is possible to employ electric power, water, LPG, oil, etc. in addition to city gas.

  In addition to the first feature configuration, the security system according to the present invention has a second feature that the reference value is a past utility usage result value in the monitoring target.

  According to the second characteristic configuration of the system of the present invention, it is possible to compare the past utility usage actual value to be monitored with the latest usage data. At this time, for example, when the latest usage data is extremely small compared to the past actual usage value, the time that the owner or the related party stayed within the monitoring target in the latest period is the past comparison target. It can be concluded that the time was short compared with the period, that is, it can be determined that the state is in a high risk state.

  In addition to the first or second feature configuration, the security system according to the present invention is a standard past utility usage actual value of a utility user showing the same attribute as the monitoring target in addition to the first or second characteristic configuration. It is a third feature.

  The above-mentioned attributes include the family structure of the user's home (single-person household, elderly couple household, couple-only household, couple and children household, etc.), total floor area, and types and number of gas appliances (floor heating installation area, gas Fan heater total output, gas stove size, stove number, etc.). When the number of people at home increases, human activities increase, so the amount of utility usage increases and the number of people increases, so the security risk decreases. For this reason, based on the information about the user home family structure, the risk evaluation unit has a lower security risk for a user home with a large number of members constituting a family compared to a user home with a small number of members constituting a family. It is good as what evaluates.

  According to the third characteristic configuration of the system of the present invention, it is possible to compare a standard utility usage actual value configured with the same attribute as the monitoring target and the latest usage data. At this time, for example, when the most recent usage data is significantly smaller than the standard utility usage actual value, the time that the owner or related person stayed in the monitoring target in the most recent period is past. It is possible to conclude that it was a short time compared to the comparison target period, i.e., it is possible to determine a high-risk state. Furthermore, a more rigorous risk evaluation can be performed by combining with past performance values in the monitoring target.

  Further, the security system according to the present invention provides a security service provided to the monitoring target by performing a predetermined calculation based on the index value in addition to any one of the first to third characteristic configurations. A fourth feature is that a billing fee calculation unit for calculating a billing fee is provided.

  According to the fourth characteristic configuration of the system of the present invention, the billing fee for the security service providing destination is a fee system according to the security risk, so that it is possible to set a fairer fee than the conventional pay-per-use system.

  In addition, since the charging fee for the security service is calculated based on the utility usage, if the utility provider and the security service provider are, for example, companies related to each other, the fee for the utility usage And security service charges can be billed together, and the efficiency of charge collection work can be improved.

  On the other hand, for users with a large amount of utility usage, the fee for utility usage increases, while the security risk decreases, so the fee for security services decreases. Conversely, the month when utility usage is low. The security risk increases, but the fee for the security service will increase, but the fee for the utility usage will decrease, so the fee fluctuation will be leveled out considering the total fee for the utility usage and the security service fee There is an effect.

  Further, the security system according to the present invention includes the monitoring measured at predetermined intervals by the utility usage measuring means installed in the monitoring target in addition to any one of the first to fourth characteristic configurations. A fifth feature is provided with a second storage unit in which, when the utility usage amount in a target is input via a telecommunication line, information on the utility usage amount is stored so as to be readable from the index value calculation unit. To do.

  At this time, a gas meter, a watt hour meter, a water meter, an oil meter, etc. can be used as the utility usage measuring means. Moreover, the configuration may be such that information relating to the usage amount is input from the measurement means to the system of the present invention via a telecommunication line, and the information relating to the usage amount measured by the measurement means is provided by the present invention from other telecommunication terminals. It does not matter as a configuration input to the system.

  In addition to the fifth feature configuration, the security system according to the present invention includes each of the monitoring targets measured every predetermined period by each utility usage measuring unit installed in the plurality of monitoring targets. When the utility usage amount is input via the telecommunications line, information on each utility usage amount is stored in the second storage unit, and the index value calculation unit is configured to use the utility usage amount for each monitoring target. From the second storage unit to calculate the index value, and the risk evaluation unit evaluates the security risk based on the index value corresponding to each monitoring target.

  According to the sixth characteristic configuration of the system of the present invention, it is possible to realize the security risk evaluation for each of a plurality of security service providing destinations by one system. Also, when using past utility usage actual values by users of the same attribute as reference values, for example, the past actual values of all corresponding providers are read from the first storage unit and average values are calculated. By using this calculation result as a reference value, the index value calculation unit can calculate the index value. For this reason, the information stored in the 1st memory | storage part is automatically updated by setting it as the structure by which the newest performance value given sequentially is stored in a 1st memory | storage part, and, thereby, a standard usage amount actual value Need not be reviewed regularly.

  In addition to the sixth feature configuration, the security system according to the present invention reads out each security risk for each of the plurality of monitoring targets from the risk evaluation unit, and also reads the plurality of read security risks. A seventh feature is that a warning level determination unit that determines a warning level of an area including the plurality of monitoring targets according to the size is provided.

  Here, as a method of determining the alert level according to the size of the security risk, for example, monitoring when individually monitoring each jurisdiction area from a security center capable of integrally monitoring a plurality of jurisdictions Depending on the length of time distributed in proportion to the ratio of the number of suppliers (hereinafter referred to as “high risk rate”) showing a value that exceeds the value of the security risk that is a predetermined standard Determine the number of security guards to be dispatched when the security sensor is activated, or arrange the number of security center personnel in charge of each area to the high risk rate ratio. It is possible to arrange them accordingly.

  According to the seventh feature configuration of the present invention, by placing a limited number of security guards by making a decision to raise the warning level in advance for an area that is determined to have a high security risk, Since it can be placed intensively in areas with a relatively high security risk, it is possible to shorten the time required for the security guards to go to the site when a vacant nest or the like actually occurs, and the clearance rate is improved.

  The charging fee calculation method according to the present invention is a charging fee calculation method for calculating a charging fee for a security service provided to a monitoring target by data processing of a computer, wherein the monitoring target is measured every predetermined period. A utility usage amount input step, a reference value derivation step having a predetermined relationship with the utility usage amount stored in advance, and a predetermined calculation using the reference value to perform a predetermined calculation in the monitoring target The method includes a step of calculating an index value indicating a person's activity state, and a step of calculating the charging fee by performing a predetermined calculation based on the index value.

  According to the method of the present invention, the billing fee for the security service can be automatically calculated by computer processing based on the utility usage amount.

  According to the present invention, since it is possible to evaluate the level of security risk with respect to the monitoring target based on the utility usage, it is possible to objectively and quantitatively evaluate the risk. As a result, for example, it is possible to provide a fair and safe security service such as setting a service provision fee according to a security risk and setting a warning level according to the risk.

  Hereinafter, embodiments of a security system according to the present invention (hereinafter referred to as “the present invention system” as appropriate) will be described with reference to the drawings.

  The system of the present invention is a security system that makes it possible to quantitatively evaluate the security risk of a security service provider by computer arithmetic processing, and is composed of computer hardware and application software executed on the hardware. ing. Here, when calculating for risk evaluation, information on the utility usage of the security service provider is used. In the following embodiments, city gas is taken as an example of the utility. However, the utility is not limited to city gas, and other utilities such as power, water, LPG, and oil may be used.

<First Embodiment>
A first embodiment of the system of the present invention (hereinafter referred to as “this embodiment” as appropriate) will be described with reference to FIG.

  FIG. 1 is a block diagram showing a schematic configuration of the system of the present invention in this embodiment. As shown in FIG. 1, the system 1 of the present invention includes a storage unit 11, an index value calculation unit 12, and a risk evaluation unit 13. As will be described later, the storage unit 11 includes a measurement information storage unit 11A that stores measurement information and a record information storage unit 11B that stores record information.

  In FIG. 1, a city gas user's house 2 is assumed as a security service providing destination, and a gas meter 21 for measuring the amount of gas used is installed in the user's house 2. The gas meter 21 can be connected to the inventive system 1 via the telecommunication line 3, and the gas usage measured by the gas meter 21 is given to the inventive system 1 via the telecommunication line 3. is there.

  The gas meter 21 measures the amount of gas used in the user's house 2 within a predetermined period (for example, for one month), and transmits the amount of use data to the system 1 of the present invention via the telecommunication line 3. The system 1 of the present invention stores the usage data received via the telecommunication line 3 in the measurement information storage unit 11A. In the following, the gas usage for the most recent month is given to the present system 1 every month.

  On the other hand, the past gas use amount actual value in the user's house 2 is stored in the result information storage unit 11B. When the information sent from the gas meter 21 to the telecommunication line 3 is only the instruction value data indicated by the current gas meter 21, the difference from the instruction value data up to the previous month stored in the record information storage unit 11B is obtained. The gas usage data for this month calculated by taking the data is stored in the measurement information storage unit 11A.

  When the usage data for the current month is given from the measurement information storage unit 11A, the index value calculation unit 12 reads the actual usage data for the same month of the previous year from the actual information storage unit 11B and calculates the reciprocal of the ratio with the current month usage. (Refer to Equation 1). Hereinafter, the calculated value is referred to as “index value”, and the reference value read from the record information storage unit 11 for calculating the “index value” is referred to as “reference value”. Then, the index value calculation unit 12 outputs the calculated index value to the risk evaluation unit 13.

(Equation 1)
Index value = 1 / (current month usage / previous year same month usage)

  The risk evaluation unit 13 evaluates the security risk for the user's home 2 based on the index value given from the index value calculation unit 12. That is, as the index value increases, it is determined that the security risk of the user home 2 is higher. At this time, the degree of deviation of the index value from the predetermined reference value may be displayed as the risk level, or the ratio between the index value and the predetermined reference value may be displayed as the risk level.

  As described above, the index value is the reciprocal of the ratio of gas consumption for the current month to the gas consumption for the same month of the previous year.If the gas consumption for the current month has decreased compared to the same month of the previous year, this index The value gets bigger. Since the amount of gas used increases as the time spent in the user's home 2 during the period, the index value is larger in the user's home 2 for the current month compared to the same month of the previous year. It represents the short time of stay. If the staying time is short, conversely, it means that the absence time is long, that is, the security risk is high.

  In general, a space such as a residence with a high home ratio has a low risk (security risk) against suspicious person intrusion, and a space with a low home ratio has a high security risk. When the home use rate is high, if the gas use rate is high as a result of human activities, the home use rate is high and the security risk is low. On the other hand, when the gas usage is low, the home risk is low and the security risk is high. Therefore, according to the system of the present invention, specifically, the security risk for the current month can be quantitatively evaluated by performing a simple calculation using the value of the gas consumption for the current month.

  When reading the actual usage data for the same month of the previous year as a reference value, the temperature may be corrected to eliminate the effects of temperature differences between the same month of the previous year and the current month in order to perform a more rigorous evaluation. . Moreover, it is not limited to the same month in the previous year, and for example, it may be based on the average value of the actual usage amount in the same month for a plurality of years, or may be the average value of the three-month results including the two months before and after.

  In the above description, the index value is calculated using the actual value of the same month of the previous year as a reference value. For example, the standard gas of the same month by a user having the same attribute as the user who uses gas at the user's house 2 is used. The index value may be calculated using the usage amount. Here, the attributes include the family structure of the user's house (single-person household, elderly couple household, couple-only household, couple and children household, etc.), total floor area, and types and number of gas appliances (floor heating installation area, gas Fan heater total output, gas stove size, stove number, etc.).

  At this time, as the standard gas usage, the average value of past gas usage of the same month by users with the same attribute can be adopted. The index value may be the reciprocal of the ratio of the gas usage for the current month to the typical gas usage.

  Furthermore, it is good also as what uses both the track record value of the said same month last year and the standard track record value by the user of the same attribute as a reference value. In this case, for example, as shown in Equation 2, the ratio of the gas usage of the current month to the gas usage of the same month of the previous year and the gas usage of the current month relative to the standard gas usage by users of the same attribute of the same month of the previous year The index value can be obtained by the reciprocal of the value multiplied by the ratio of the quantities.

(Equation 2)
Index value = 1 / {(Usage amount of the current month / Usage amount of the same month of the previous year) x (Usage amount of the current month / Standard usage by users of the same attribute in the same month of the previous year)}

  In this way, by calculating the index value using the values of both the past results of the self and other results showing the same attribute as the reference value, and evaluating the security risk using this index value, a more rigorous risk Evaluation can be performed.

  In the above description, the index value is the reciprocal of the ratio between the amount used and the reference value for the current month. However, the gas usage of the current month for the past results within the same target or the past results by users with the same attribute. The calculation method is not limited to this method as long as the quantity situation can be objectively recognized. For example, a difference value obtained by subtracting the usage amount from the reference value can be used as the index value.

  In the above description, the gas meter 21 is configured to be connectable to the system 1 of the present invention via the electric communication line 3. However, even if the gas meter 21 does not have the function, the gas meter 21 performs measurement. Any configuration may be used as long as the amount of gas used is given to the system 1 of the present invention. For example, the indication value of the gas meter 21 is visually recognized, the indication value is input to the portable operation terminal, and the usage amount is given from the operation terminal to the system 1 of the present invention via the telecommunication line. You can also.

<Second Embodiment>
A second embodiment of the system of the present invention (hereinafter referred to as “this embodiment” as appropriate) will be described with reference to FIG. The system of the present invention in the present embodiment is different from the system of the present invention in the first embodiment in that gas usage information can be received from a plurality of security service providers. Further, the components constituting the system of the present invention are the same as those in the first embodiment.

  FIG. 2 is a block diagram showing a schematic configuration of the system of the present invention in the present embodiment. As shown in FIG. 2, the system 1 according to the present embodiment includes a plurality of user homes 2 a, 2 b,..., Gas meters 21 a, 21 b,. The amount of gas used at the user's home for the current month is given through the telecommunication line 3 and stored in the measurement information storage unit 11A. Then, the index value calculation unit 12 reads the gas use amount of the current month from the measurement information storage unit 11A and the past use amount actual value from the result information storage unit 11B for each user's home, respectively. The index value is calculated by the same method as in the first embodiment. Then, the risk evaluation unit 13 performs risk evaluation based on the calculated index value.

  At this time, the information sent from the gas meters 21a, 21b,... To the system 1 of the present invention includes information on the installation location where the gas meter is installed, that is, the user's home, in addition to the gas usage information of the current month. Information for identifying 2a, 2b,... (For example, contract number) is included.

  In addition, the record information storage unit 11B may store past record values related to all providers that provide security services in a database format. Further, the latest gas usage amount sent to the measurement information storage unit 11A may be sequentially sent to and stored in the result information storage unit 11B.

  Furthermore, by registering the attribute information of each service providing destination, as described in the first embodiment, when the past gas usage actual value of the same month by the user with the same attribute is used as the reference value, Reads out the data of the previous year of all the corresponding destinations from the record information storage unit 11B, calculates the average value, and the index value calculation unit 12 can calculate the index value by using this calculation result as a reference value. By being configured in this way, the information stored in the record information storage unit 11B is automatically updated every month, so that it is not necessary to periodically review the standard use amount record value. In addition to the past actual value of each provider, the attribute information may also be stored in the database format in the actual information storage unit 11B.

  By configuring the system 1 of the present invention in this way, it is possible to perform security risk evaluation for each of a plurality of security service providing destinations with one system.

<Third Embodiment>
A third embodiment of the system of the present invention (hereinafter referred to as “this embodiment” as appropriate) will be described with reference to FIG. The system of the present invention in the present embodiment is different from the system of the present invention in the first embodiment in that the billing fee calculation unit 14 is further provided. Other components are the same as those in the first embodiment. The form is the same.

  FIG. 3 is a block diagram showing a schematic configuration of the system of the present invention in the present embodiment. As shown in FIG. 3, the system 1 a of the present invention in the present embodiment includes a charging fee calculation unit 14 that calculates a fee for charging a security service provider as a service consideration.

  The charging fee calculation unit 14 calculates a charging fee according to the size of the security risk evaluated by the risk evaluation unit 13. For example, there is a program that incorporates a risk-based billing system that multiplies a predetermined amount each time the security risk level rises, and thereafter, the security risk is a uniform fee up to a predetermined level. The billing fee can be calculated based on the program.

  Alternatively, the billing fee may be calculated using the index value calculated by the index value calculation unit 12. At this time, for example, when the index value is calculated by the reciprocal of the ratio of the gas usage of the current month to the gas usage of the same month of the previous year, the charging fee calculation unit 14 uses a predetermined basic fee (for example, 5000 yen) as the index value. The charging fee may be calculated by multiplying.

  When configured in this way, the charging fee for the security service providing destination has a fee structure corresponding to the security risk, so that it is possible to set the fee more evenly than the conventional pay-per-use charging system.

  In addition, since the charging fee for the security service is calculated based on the gas usage, if the gas company and the security service provider are, for example, related companies, the gas fee and the security service fee Can be billed in an integrated manner, and the efficiency of fee collection can be improved.

  On the other hand, for users with high gas consumption, gas charges will increase, but security risks will decrease, and security services will decrease. Because the risk increases, the fee for the security service increases, but the gas fee decreases, so there is an effect that the fluctuation of the fee is leveled in view of the total fee of the gas fee and the security service fee.

  In the present embodiment, as in the second embodiment, the gas usage information may be received from a plurality of security service providing destinations. With this configuration, it is possible to calculate a charging fee for each security service provider by one system.

<Fourth Embodiment>
A fourth embodiment of the system of the present invention (hereinafter referred to as “this embodiment” as appropriate) will be described with reference to FIG. The system of the present invention in the present embodiment is different from the system of the present invention in the second embodiment in that the system further includes a warning level determination unit 15, and the other components are the second implementation. The form is the same.

  FIG. 4 is a block diagram showing a schematic configuration of the system of the present invention in the present embodiment. As shown in FIG. 4, the system 1 b according to the present embodiment includes a warning level determination unit 15 that determines a warning level of an area including a plurality of security service providing destinations.

  In the present embodiment, each gas meter 21a, 21b,... Measures the amount of gas used for each predetermined time period and transmits the amount of use to the system 1 of the present invention via the telecommunication line 3. It is preferable to adopt a configuration in which At this time, the day may be divided into 24 hours, and the hourly usage may be measured and transmitted, or the day may be divided into a plurality of patterns in which two or more hours are one pattern, The usage amount may be measured for each pattern and transmitted to the system 1 of the present invention. Below, it demonstrates as what is measured and transmitted for every hour.

  In the system 1 of the present invention, the gas usage record for each hour is transmitted via the telecommunication line 3 from a plurality of security service providing destinations 2a, 2b,. The transmitted information on the gas usage is stored in the measurement information storage unit 11A. Moreover, the information regarding the gas consumption according to time zone before the previous day is stored in the performance information storage unit 11B. As in the second embodiment, the record information storage unit 11B stores information for each providing destination, and these may be held in a database format. In addition, the information stored in the record information storage unit 11B may be discarded or compressed after a predetermined period of time in order to reduce the amount of information.

  The index value calculation unit 12 calculates an index value by the same method as in each of the above-described embodiments, based on the latest gas usage amount and the standard gas usage amount of the user showing the same attribute. And the risk evaluation part 13 performs the risk evaluation for every time slot | zone based on the index value calculated for every service provision destination. In addition, the result of the security risk according to this time slot | zone is hold | maintained in the performance information storage part 11B.

  FIG. 5 is an example showing the result of security risk by time zone in a certain security service providing area, and the result calculated by the risk evaluation unit 13 for each time zone is read from the record information storage unit 11B and edited and displayed. Is. As the target area, the area including all the service providers is divided into predetermined jurisdiction areas including a plurality of service providers, and exceeds the security risk that is a predetermined standard for the total number of service providers belonging to each jurisdiction area. The ratio of the number of suppliers showing the values (hereinafter referred to as “high risk rate”) is displayed in% in FIG.

  For example, according to FIG. 5, the security risk is higher in the X2 district than in the X1 district from 0 o'clock to 1 o'clock as opposed to the entire X1 district, and conversely the X1 district from 13:00 to 14:00 in comparison with the X2 district. The security risk is higher.

  Thus, by calculating the high risk rate for each time zone for each jurisdiction area, the level of security risk for each time zone can be grasped.

  As shown in FIG. 5, the alert level determination unit 15 reads out the risk evaluation result evaluated by the risk evaluation unit 13 from the result information storage unit 11B, and selects a plurality of service providing destinations as an area including all the providing destinations. It is divided for each predetermined jurisdiction area, and a high risk rate for each time zone is calculated for each jurisdiction area. And based on the level of the security risk according to the time zone according to area, the decision which strengthens the monitoring level of an area with a high security risk for every time slot | zone divided beforehand is performed. As a method of strengthening the monitoring level, for example, the monitoring time for individually monitoring each jurisdiction area from a security center that can monitor a plurality of jurisdictions in an integrated manner is divided by the high risk rate ratio. The number of security personnel dispatched when the security sensor is activated is arranged according to the ratio of the high risk rate, or the number of security center personnel responsible for each area is determined. Arrangement according to the ratio of high risk rate.

  By being configured in this way, when a limited number of guards are placed, it can be placed in an area with a relatively high security risk, so if there is actually a vacant nest, etc. The dispatch time of security guards to the site can be shortened, and the clearance rate is improved.

  In FIG. 5, the alert level is determined by the high risk rate for each time zone. For example, the alert level is determined by further calculating the high risk rate by distinguishing between weekdays and holidays. It does not matter. Moreover, the decisive factor of the alert level is not limited to the ratio that the security risk is at a high level. For example, the alert level may be determined to increase the alert level for an area having a high absolute number of destinations indicating a high level. .

  Furthermore, in addition to the configuration of the present embodiment, the configuration may be such that the accounting fee calculation unit 14 described in the third embodiment is provided. The present invention system 1c shown in FIG. 6 is configured to further include a billing fee calculation unit 14 in addition to the present invention system 1b shown in FIG.

  At this time, in addition to the charging system according to the index value based on the monthly gas usage amount of each provider, the charging fee calculation unit 14 determines whether or not it falls in an area with a high high risk rate for each time zone. It is possible to further differentiate the settings. For example, a value obtained by multiplying a predetermined reference charge by a high risk rate is calculated for each time zone, and the sum total over one month is calculated. Further, according to the monthly risk-based billing system described in the third embodiment The calculated fee may be combined with the calculated fee. By being configured in this way, in addition to the security risk of the provider, the fee system takes into account the security risk of the entire area including the provider, so that a more fair fee can be set.
