Description

  The present invention relates to an environment conflict detection apparatus, method, and program used for detecting environment conflicts in a space where a plurality of real space services operate in parallel and in adjacent space-times in a real space service providing system.

  In recent years, a system has been proposed that provides various real-space services to users using devices such as home appliances, information devices, sensors, and actuators interconnected by a network. For example, in the field of home network services, sensors that detect temperature, humidity, human sensation, body movement, and biological information where a user exists and devices such as air conditioners, sashes, doors, and television receivers are used. Provide various real space services such as sleep support, sash control, crime prevention control, and health care.

  As a more specific configuration for realizing this type of system, for example, a method of executing a real space service using an agent model in which an agent is defined for each user, place, and device has been proposed (for example, a patent) (See Reference 1 or Patent Reference 2). By using such a method, a desired real space service can be realized by appropriately linking agents.

Japanese Patent No. 4779027 JP 2012-18608 A

  However, the conventional real space service providing system has the following problems to be solved. In other words, when there are multiple spatial services that affect a specific space, environmental factors such as physical logic resources such as sound, light, temperature, current, radio waves, odor, and psychology such as the tension of the place May have an impact on physical resources. This effect on environmental factors is called environmental competition. Environmental competition can be broadly divided into competition between space and space, and time-series competition in the same space, and countermeasures are required for each. However, an effective index for detecting environmental competition has not yet been found, and an effective countermeasure is eagerly desired.

  The present invention has been made by paying attention to the above circumstances, and the object of the present invention is to make it possible to accurately express environmental competition with a simple index, thereby making environmental competition at least in the same time and space relatively easy and accurate. It is an object of the present invention to provide an environmental conflict detection apparatus, method, and program which can be detected in a simple manner.

In order to achieve the above object, a first aspect of the present invention is an environment conflict detection apparatus used in a real space service execution system that executes a plurality of real space services for each space, and is prepared for each space. In the storage means, a degree of exclusiveness indicating a degree that each of the plurality of real space services does not want to change the environmental factor of the space is stored in association with the real space service . Then, when executing the real space service in the space, the first influence degree that the execution of the real space service gives to the environmental factor of the space is calculated, and the calculated first influence degree is Compared with the degree of possession for the environmental factor stored in advance in association with another real space service executed at the same time in the same space as the space, and based on the first determination information representing the comparison result The real space service execution is determined to be permitted or not.

According to a second aspect of the present invention, the storage means further stores a first propagation rate indicating a degree of propagation of the environmental factor between the space and the adjacent space at the same time. Based on the first propagation rate, when the real space service is executed in the space, the second influence degree that the execution of the real space service gives to the environmental factor of the adjacent space at the same time is further calculated. Then, the calculated second influence degree is compared with the degree of possession with respect to the environmental factor stored in the storage means in association with another real space service executed in the adjacent space at the same time, and it is obtained so as to determine whether to permit the execution of the real space service based on the second determination information and the first determination information representing the comparison result.

Then, based on the third determination information representing the comparison result and the first determination information, whether to execute the real space service is determined.

Further, according to a fourth aspect of the present invention, the storage means further stores a third propagation rate indicating a degree of propagation between the space of the environmental factor and the adjacent space of the adjacent time, and stores the third propagation rate. Based on the third propagation rate, when executing the real space service in the space, the fourth influence degree that the execution of the real space service has on the environmental factor in the space adjacent to the space and in the adjacent time And the calculated fourth influence degree is compared with the degree of exclusiveness stored in the storage means in association with another real space service executed in the adjacent space in the adjacent time zone, based on the fourth determination information and the first determination information representing the comparison result of that, it is obtained so as to determine whether to permit the execution of the real space service.

According to the first aspect of the present invention, when a real space service is executed in a certain space and another real space service is executed at the same time in the same space as that space, the real space service is changed in the space. By executing, the first degree of influence given to the environmental factor of the space is calculated, and the calculated first degree of influence is associated with another real space service that is simultaneously executed in the same space as the space. by comparing the stored exclusive of Te, whether the execution of the real space service is permissible it is determine constant. For this reason, when multiple real space services are executed simultaneously in the same space, it is possible to easily and accurately detect environmental conflicts between these real space services before the real space service is executed.

According to the second aspect of the present invention, when a real space service is executed in a certain space and another real space service is executed in a space adjacent to the same time, The second degree of influence given to the environmental factor of the real space service is calculated based on the first propagation rate indicating the degree of propagation between the space of the environmental factor and the adjacent space at the same time. Whether or not the execution of the real space service is permitted by comparing the calculated second degree of influence with the degree of exclusiveness stored in association with another real space service executed in the adjacent space at the same time or it is determine constant. For this reason, even when real space services are executed in two adjacent spaces at the same time, environmental conflicts between these real space services can be detected easily and accurately before the real space services are executed.

  FIG. 2 is a block diagram showing a functional configuration of the space servers SVα, SVβ, SVγ, SVδ. The spatial servers SVα, SVβ, SVγ, and SVδ include a control unit 1, a storage unit 2, and an input / output interface unit 3.

  The input / output interface unit 3 transmits / receives information to / from the service server SVs, the environmental contention arbitration service server SVp, and a space server in an adjacent space via a network (not shown).

  The storage unit 2 includes a nonvolatile memory such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) that can be written and read as needed as a storage medium, and a propagation rate database (propagation rate DB) 21 is provided in the storage area. And an exclusiveness database (exclusiveness DB) 22 is provided.

  The propagation rate DB 21 stores information representing the propagation rate distributed from the service server SVs. The propagation rate is a time unit representing the degree of transmission according to environmental factors between the own space and the adjacent space for each of the spaces α, β, γ, and δ. The propagation rate is set, for example, by the system operator or the real space service provider actually measuring the propagation rate for each environmental factor between adjacent spaces α, β, γ, and δ in time units. FIG. 4 shows information representing the propagation rate set for the space α as an example.

  The exclusiveness DB 22 stores information representing the exclusiveness distributed from the service server SVs. The degree of occupancy represents the degree to which the space α, β, γ, δ does not want to change the environmental factor of the space when the space is executed in the space. , Β, γ, and δ are set in units of time for each environmental factor. FIG. 3 shows an example of this, and shows the degree of exclusiveness information set for the space γ. The degree of exclusiveness is arbitrarily set by the real space service provider.

  FIG. 5 shows an example of information representing the degree of occupation and propagation rate set for time (t) in each of the spaces α, β, γ, and δ. This example is set on the premise that the kitchen does not face the garden, and “sleep support” is used in the bedroom, “cooking support” is used in the kitchen, and “TV watching” is used in the living room. Further, the propagation rate may be dynamically changed depending on the situation (weather, opening / closing of windows, learning results, etc.). In addition, when a space (π) is defined in which the propagation rate of “current” between all spaces is “1” and the degree of occupancy is “100”, it is possible to express environmental competition regarding breakers (resources).

  FIG. 6 shows an example of propagation rate information set for the adjacent time (t to t + 2) in each of the spaces α, β, γ, and δ. In this example, the influence of most environmental factors does not propagate in the time axis direction because the garden is outside air, but the influence is propagated for some environmental factors in a relatively open living room. It was set in consideration of the strong influence transmitted in the bedroom. For example, in order to perform “sleep support” from time t + 2 in the bedroom, if the degree of occupancy is reserved in Sα (t + 2), the effect before time t + 2 may interfere due to temperature or odor. ing.

  Environmental factors include physical resources, logical resources, and psychological resources. The physical resources are sound, light, temperature, humidity, radio wave, odor, wind direction, wind speed, and the like, all of which can be acquired by a sensor. Logical resources are defined by standards such as current, capacity, and maximum load capacity. Psychological resources are a sense of tension and atmosphere (brightness, cleanliness, etc.) in a space (place), and can be acquired by detecting and analyzing the behavior of a service user using a vital sensor or the like.

  By using these environmental factors, for example, if you focus on current, you will compete for breakers, and if you focus on radio waves, you will compete with devices that generate radio waves in the same frequency band, such as microwave ovens and Bluetooth (registered trademark) speakers. In addition, it is possible to detect a user's psychological competition by paying attention to the tightness of the space (place).

  The adjacent space-time link structure shown in FIGS. 5 and 6 may or may not be a full mesh. That is, whether or not the propagation rate is set to “0” or more may be set so that a space group with the same management entity is a full mesh and only a related part is linked to a space group with a different management entity. In addition, the propagation rate set for the link in the adjacent space-time may be symmetric or asymmetric with respect to the direction, and the propagation rate set for the time axis may have a different value between specific times. Furthermore, it is possible to use only the adjacent time set in the same space.

  All of the control units 1 of the spatial servers SVα, SVβ, SVγ, SVδ are provided with a CPU (Central Processing Unit). As main control functions necessary for carrying out the present invention, an influence degree calculation unit 11 and a degree of exclusiveness allowance determination are provided. Unit 12 and a determination result output unit 13. All of these control functions are realized by causing the CPU to execute a program stored in a program memory (not shown).

  Prior to the execution of the real space service, the influence degree calculation unit 11 requests the environmental competition mediation service server SVp to evaluate the influence degree with respect to the environmental factor, and thereby the environmental factor of the space-time corresponding to the execution of the real space service. The process of obtaining the calculation result of the evaluation of the degree of influence on the image is performed.

  The exclusiveness allowance determination unit 12 determines that the real space service is the same based on the calculation result of the acquired evaluation of the influence degree and the exclusiveness and propagation rate stored in the propagation rate DB 21 and the exclusiveness DB 22. Whether the impact on time space, adjacent time of the same space, adjacent space of the same time, and other real space services executed in the adjacent space time is allowed is determined. Processing is sequentially performed in a chained manner until the threshold value is reached.

  The determination result output unit 13 grants the execution of the real space service based on the detection result by the exclusiveness allowance determination unit 12 so long as the influence is allowable, and exceeds the allowable range. If yes, the execution of the real space service is rejected, and processing for requesting mediation from the environmental competition mediation service server SVp is performed.

(Operation)
(1) Setting of Propagation Rate and Degree of Exclusiveness for Spatial Server First, the propagation rate and degree of exclusiveness are set for the spaces α, β, γ, and δ. First, with regard to the propagation rate, for example, the system operator actually measures the propagation rate for each environmental factor among the spaces α, β, γ, and δ in time units, and information on the propagation rate obtained thereby is obtained from the service server SVs. This is set by delivering to the corresponding spatial servers SVα, SVβ, SVγ, SVδ. An example of the setting result is as shown in FIGS.

  Next, with respect to the degree of exclusiveness, as shown in FIG. 7, the provider of the real space service arbitrarily determines the degree of exclusiveness for each real space service, and the information on the degree of exclusiveness is obtained from the service server SVs. Declare in step (1) to the server SVα (α is illustrated in FIG. 7). The space server SVα stores the exclusiveness information sent from the service server SVs in the exclusiveness DB 22 in steps (2) and (3) under the control of the management program. The example of FIG. 7 shows a case where the degree of occupation [X] is declared and set for the environmental factor [A] at the time [T] for the real space service [F].

  FIG. 8 is a flowchart showing the procedure and details of the setting process of the exclusiveness information. The service server SVs transmits the degree of exclusiveness [X] input by the service provider in step S1 to the corresponding spatial server SVα. The space server SVα stores the setting information {{T, {A, X}} of the exclusiveness sent from the service server SVs in the exclusiveness DB 22 in association with the time (t) in step S2. In step S3, the setting information of the exclusiveness is stored in the exclusiveness DB 22 in association with the adjacent times (t + θ) and (t−θ). Similarly, the setting information {{T, {A, X}} for the degree of exclusiveness for each environmental factor is stored in the exclusiveness DB 22 in time units for each real space service.

  Note that the setting information {{T, {A, X}} of the degree of exclusiveness stored in the degree of exclusiveness DB 22 indicates that the execution of the real space service ends in step S4, and that is notified from the service server SVs. In steps S5 and S6, they are released, that is, deleted from the exclusiveness DB 22.

(2) Detection of environmental competition due to execution of real space service Here, as described in (1) above, the setting information of propagation rate and occupancy is stored in each space server SVα, SVβ, SVγ, SVδ. An example will be described in which the service server SVs executes a real space service in the space α and drives a device [D] such as an audio device or an air conditioner. FIG. 9 is a diagram showing an outline of the operation.

  The service server SVs requests the space server SVα to drive the device [D] in step (1) according to the program of the real space service to be executed. First, in step (2) and (3), the space server SVα requests the environment competition mediation service server SVp to evaluate the degree of influence on the environment by driving the device [D] under the control of the management program. On the other hand, the environmental competition mediation service server SVp evaluates the degree of influence of the device [D] to be driven in the space α on each environmental factor of the space α, and sends the evaluation result to the requesting space server SVα. Return it.

  Next, in step (4), the spatial server SVα determines whether the degree of influence exceeds the degree of possession corresponding to the current time (t) stored in the degree of occupation DB 22 for the returned impact evaluation result for each environmental factor. Determine whether or not. In step (5), the propagation rate for the adjacent space and the adjacent time is read from the propagation rate DB 21 for each environmental factor, and based on the degree of influence evaluated by the environmental contention arbitration service server SVp and the read propagation rate. The degree of influence on the adjacent space is calculated. Then, the calculated degree of influence on the adjacent space is transferred to the space server SVβ of the adjacent space β in steps (6) and (7).

  Whether the spatial server SVβ exceeds the degree of exclusiveness corresponding to the current time (t) stored in the exclusiveness DB 22 in steps (6) and (7) under the control of the management program. Determine whether or not. Then, the determination result is returned to the requesting space server SVα.

  In step (8), the space server SVα reads the propagation rates at the adjacent times (t + θ) and (t−θ) in the space α from the propagation rate DB 21, and the influence evaluated by the environmental contention arbitration service server SVp. The influence degree of the adjacent times (t + θ) and (t−θ) in the space α is calculated based on the degree and the read propagation rate. Then, it is determined whether or not the degree of influence at the calculated adjacent time (t + θ) and (t−θ) of the space α exceeds the degree of possession corresponding to the current time (t) stored in the degree of possession DB 22. judge.

  Furthermore, in steps (9) and (10), the space server SVα transfers the degree of influence at the adjacent times (t + θ) and (t−θ) calculated to the space server SVβ in the adjacent space β. The spatial server SVβ, under the control of the management program, in steps (9) and (10), the transferred influence degree is stored in the exclusive time DB 22 at the adjacent times (t + θ) and (t−θ). It is determined whether or not the degree of occupancy is exceeded. Then, the determination result is returned to the requesting space server SVα.

  Based on the determination results in steps (4) to (10), the space server SVα drives the device [D] with the real space service to be executed if each influence level is less than the exclusive level. To give permission. On the other hand, if any one of the influence degrees exceeds the exclusive degree, the drive of the device [D] is rejected. If the degree of influence exceeds the degree of exclusiveness, the mediation request is made to the environmental competition mediation service server SVp.

Next, the above detection operation will be described in more detail. 10 and 11 are flowcharts showing the processing procedure and processing contents.
In accordance with the real space service program to be executed, the service server SVs requests the space server SVα to drive the device [D] [E] in step S1. The space server SVα first identifies the type [K] of the device [D] from the request information in step S2 under the control of the management program. Then, the evaluation request for the degree of influence including the type [K] of the specified device [D] is transmitted to the environmental contention arbitration service server SVp.

  On the other hand, in step S3, the environmental competition mediation service server SVp evaluates the degree of influence [Z] on the environmental factor due to the drive [E] of the device [D] of the type [K] in response to the evaluation request. For this evaluation, for example, in correspondence with the space α, a memory table in which the degree of influence is registered for each environmental factor for all models of all devices that are supposed to be driven is created in advance, and the degree of influence corresponding to the memory table is created. This is done by reading Note that an influence degree calculation formula may be stored, and the influence degree may be calculated according to the calculation formula, or the influence degree may be obtained using both the memory table and the calculation formula.

  When the evaluation result of the degree of influence [Z] is returned from the environmental competition mediation service server SVp, the space server SVα is set for other real space services at the current time (t) of the space α in step S4. The obtained degree of exclusiveness is read from the exclusiveness degree DB 22, and the returned influence degree [Z] for each environmental factor is compared with the read degree of exclusiveness. That is, the environmental conflict determination (i) described above is performed. If the degree of influence [Z] is less than or equal to the degree of exclusiveness set for all other real space services executed in the same space α at the same time, it is determined that there is no concern about environmental conflicts. Then, the process proceeds to step S5.

  On the other hand, if the degree of influence [Z] exceeds one of the degrees of exclusiveness set for other real space services executed in the same space α at the same time, the environmental contention arbitration service server SVp In response to the request for mediation, the environmental competition mediation service server SVp performs mediation processing in step S98. In this arbitration process, for example, a priority order is set between real space services or between devices, a real space service or device having a high priority is selected according to this priority order, and the result is sent to the requesting space server SVα. It is done by notifying. Note that the earlier drive request timing may be selected.

  The space server SVα next evaluates the influence on the adjacent space-time in step S5. In this evaluation, the propagation rate corresponding to the adjacent space and the adjacent time is read from the propagation rate DB 21 for each environmental factor, and is read out with respect to the influence degree [Z] previously evaluated by the environmental competition mediation service server SVp. Multiplying by the propagation rate of the adjacent space and the adjacent time for each environmental factor ([P] = [Z] × propagation rate). The evaluation calculation of the influence degree [P] in the adjacent space and the adjacent time is performed in principle for all the adjacent spaces and all the times, but may be omitted for the space and time where the propagation rate is zero.

The space server SVα transfers the calculated evaluation result [P] of the influence degree in the adjacent space to the adjacent space server (for example, SVβ). On the other hand, the adjacent space server SVβ reads out the degrees of exclusiveness set for the other real space services in association with the same time (t) of the space β in step S6 from the exclusiveness DB 22 and transfers them as described above. The degree of influence [P] for each environmental factor is compared with the read degree of possession. That is, the environmental conflict determination (ii) described above is performed. If the degree of influence [P] is equal to or less than the degree of exclusiveness set for all other real space services executed in the adjacent space at the same time, it is determined that there is no concern about environmental conflicts. The process proceeds to step S7.
If the degree of influence [P] exceeds one of the degrees of exclusiveness set for other real space services executed in the adjacent space at the same time, the same as in the case of (i) above. Next, it requests mediation from the environmental competition mediation service server SVp.

  The determination of the degree of influence on the adjacent space of the same time (t) performed in steps S5 and S6 is sequentially executed in adjacent space servers until the propagation rate becomes equal to or less than a threshold value, for example. That is, the determination process of environmental competition for other real space services executed in the adjacent space server is sequentially performed in a chain from the closest to the far from the space server SVα until the propagation rate falls below the threshold value. .

Next, in step S8, the space server SVα reads out the degrees of exclusiveness set for other real space services in association with the adjacent times (t + Δ) and (t−Δ) of the space α from the exclusiveness DB 22 respectively. . Then, the degree of influence [P] for each environmental factor calculated in step S5 is compared with the read degree of exclusiveness. That is, the environmental conflict determination (iii) described above is performed. As a result of the determination, if the degree of influence [P] is equal to or less than the degree of occupancy set for all real space services in the adjacent time in the same space α, it is determined that there is no concern that environmental conflict will occur. The process proceeds to S9.
In the case of (i) and (ii) above, if the degree of influence [P] exceeds one of the degrees of possession set for other real space services executed in the adjacent time of the same space α In the same manner as described above, the environmental competition mediation service server SVp is requested to mediate.

Next, in step S9, the space server SVβ reads the degrees of exclusiveness set for the other real space services in association with the adjacent times (t + Δ) and (t−Δ) of the space β from the exclusiveness DB 22, respectively. Then, the transferred degree of influence [P] for each environmental factor is compared with the read degree of possession. That is, the environmental conflict determination (iv) described above is performed. If the degree of influence [P] is less than or equal to the degree of occupancy set for all other real space services executed at adjacent times (t + Δ) and (t−Δ) in the space β, the environment It is determined that there is no risk of competition, and the process proceeds to step S10.
When the degree of influence [P] exceeds one of the degrees of exclusiveness set for other real space services executed at the adjacent time in the space β, the above (i) to (iii) In the same manner as in, the mediation request is made to the environmental competition mediation service server SVp.

  The determination of the degree of influence of the adjacent time on the adjacent space performed in step S9 is sequentially performed in the adjacent space server until, for example, the propagation rate becomes equal to or less than the threshold value. That is, the determination process of environmental competition for other real space services executed in the adjacent space server is sequentially performed in a chain from the closest to the far from the space server SVα until the propagation rate falls below the threshold value. .

  Finally, in step S10, the space server SVα determines whether or not the degree of influence [P] is within the allowable range according to the degree of occupancy set for the real space service executed at the adjacent time of the adjacent time. If the influence degree [P] is within the allowable range as a result of the determination, the process proceeds to step S11, and a signal for permitting the drive [E] of the device [D] is output.

  On the other hand, when the degree of influence [P] exceeds the allowable range, the environmental competition mediation service server SVp is requested for mediation as in the cases (i) to (iii) described above.

  If it is determined that the mediation is not successful as a result of the mediation by the environmental competition mediation service server SVp, the process proceeds to step S99, and a signal for rejecting the drive [E] of the device [D] is output.
