  In the device control apparatus described above, if the conditional expression set in the program (for example, firmware) for operating the apparatus is satisfied by the value obtained by the sensor, the control contents of the device set in the program are also executed. To control the equipment.

  However, the sensor has been changed to another sensor with a different manufacturer or specification. In that sensor, the interface, protocol, and detection interval with the device control device are different from those before the change. As a result, it may not be possible to perform correct device control.

  In that case, it is necessary to modify a program for operating the apparatus or to replace the apparatus itself. Even if a new sensor is added, it is necessary to modify the program. Therefore, the labor for changing or adding the sensor is great.

  In addition, when one of the two conditional expressions is satisfied, the other may always be satisfied. At this time, the control content when one conditional expression is satisfied and the control content when the other conditional expression is satisfied are executed. However, for example, the control content of turning on the device and the control content of turning off the device may contradict each other, but the above device control device cannot detect such a contradiction. I can't do that.

  In addition, the detection result changes only for a short time due to noise or the like, and there is a possibility that the device is controlled unexpectedly.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a device control apparatus that reduces labor during sensor change or addition.

  Another object of the present invention is to provide a device control apparatus that can detect contradictions in control contents.

According to the first aspect of the present invention, when changing or adding a sensor, the state information storage means changes the state information for the sensor before the change to the state information for the sensor after the change, or an added sensor. By creating and storing status information for use, correct device control can be performed, and therefore, changes in the program for operating the device control apparatus and replacement of the apparatus are not affected, and labor can be reduced.

For example, the device control device reads state information including one of two sensor conditions including the same sensor type and the same sensor identification information and state information including the other from the state information storage unit, and the one state information When the sensor condition of the other state information is satisfied, it is determined whether or not the sensor condition of the other state information is satisfied. When the state corresponding to the sensor condition of the one state information is satisfied, the sensor condition of the other state information is When it is determined whether or not the corresponding state is always satisfied, and at least when the state corresponding to the sensor condition of one state information is satisfied, it is determined that the state corresponding to the sensor condition of the other state information is always satisfied , from the control information storage unit includes state identification information of the control information and other status information includes status identification information of one of the state information control It reads information comprises determining control contents contradiction judging means for determining whether or not the control content that conflict with each other in both the control information.

Whether or not a state corresponding to the state identification information of the state information is established for each piece of state information stored in the state information storage unit by the state establishment determination unit structured in the device control device , the determination result by the sensor condition establishment determining means, or, using the determination result by the sensor condition establishment determining means, by judging whether the logical expression of the corresponding is satisfied, determine If then, the device control means arranged to said device control apparatus, for each condition information stored in said state information storage means, the state corresponding to the state identification information of the state information is determined to be satisfied Then, the control information including the state identification information is read from the control information storage unit, and the device is controlled according to the control content of the control information .

According to the second aspect of the present invention, when the sensor is changed or added, the state information for the sensor before the change is changed to the state information for the sensor after the change or added in the state information storage means. By creating and storing status information for use, correct device control can be performed, and therefore, changes in the program for operating the device control apparatus and replacement of the apparatus are not affected, and labor can be reduced.

For example, the control content contradiction determining unit configured in the device control device includes state information including one of two sensor conditions including the same sensor type and the same sensor identification information and the other from the state information storage unit. The state information is read, and when the sensor condition of one state information is satisfied, it is determined whether the sensor condition of the other state information is always satisfied, so that the state corresponding to the sensor condition of one state information is satisfied Sometimes it is determined whether or not a state corresponding to the sensor condition of the other state information is always satisfied, and at least when a state corresponding to the sensor condition of the one state information is satisfied, it corresponds to the sensor condition of the other state information When it is determined that the state is surely established, the control information including the state identification information of one state information and the other from the control information storage unit Reading control information including a state identification information of the state information determines whether or not the control contents of both control information are inconsistent with each other.

By doing so, it is possible to detect a contradiction in the control contents.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration and a usage form of a device control apparatus 1 according to the present embodiment.

  The device control apparatus 1 is connected to one or more sensors S, one or more devices D, and an input device (not shown) such as a keyboard, and operates by a computer program (software). The sensor S detects, for example, temperature, illuminance, door opening / closing, and the presence of a person. The device D is, for example, an illumination (light) or an air conditioner (air conditioner).

  The device control apparatus 1 includes a state information storage unit 11 that stores state information in which a sensor condition that is a condition of a value obtained by detection performed by the sensor S on a detection target is stored, and detection performed by the sensor S. The conversion unit 12 that converts the obtained result into a value, and the state information is read out from the state information storage unit 11, and a sensor condition establishment determination that determines whether or not the sensor condition of the state information is satisfied by the converted value Part 13 and whether or not the state defined by the state information is established is determined by the determination result obtained by the determination of the sensor condition establishment determination unit 13 and the determination by the state establishment determination unit 14 The device control unit 15 that controls the device D in accordance with the determination result obtained in step S1 and the control information in which the control content when the state determined by the state establishment determination unit 14 is established are stored. Two pieces of state information are read from the control information storage unit 16 and the state information storage unit 11, and when the sensor condition of one state information is satisfied, it is determined whether the sensor condition of the other state information is always satisfied. Thus, when the state of one state information is established, it is determined whether or not the state of the other state information is always established. If so, one state is established from the control information storage unit 16. Control information including the control content at the time and control information including the control content when the other state is established, or control information including both control content, and determining whether or not the two control content contradict each other And a contradiction determination unit 17. Each storage unit is configured in a main storage device (memory) or an external storage device.

  The status information is created according to the wishes of the user who uses the device control apparatus 1 or the device D. That is, the state is defined by the user.

  FIG. 2 is a diagram illustrating state information. The status information is created in a language called XML (Extensible Markup Language) as shown in FIG. 2 by operating the input device, for example.

  The state information St1 shown in FIG. 2 is obtained by detection performed by a sensor S (referred to as a projector sensor) in which the identification information (id) is set to 1 in a type (Type) called a projector sensor (Projector Sensor). Sensor condition CP (<and id = “1”> and </ and> surrounded by <sensor id = “1”>, </ sensor> and these tags) Part) and a condition of a value obtained by detection performed by a sensor S (referred to as an illuminance sensor) in which identification information (id) is set to 1 in a sensor S of a type (Type) as an illuminance sensor (Illuminate Sensor) <Sensor in the part enclosed by the condition CI (<and id = “2”>) and </ and> id = “2”>, </ sensor>, and a portion surrounded by these tags), and includes <event id = “1”> and </ event>, so that state information The identification information (id) is 1 in FIG.

  The state information St1 indicates that the state of the state information St1 is satisfied when one or both of the conditions are satisfied by surrounding the sensor condition CP and the sensor condition CI with <or> and </ or>.

  The sensor condition CP includes a conditional expression of value = 0 (<condition> == </ condition> and <value> 0 </ value>), and a time length of 60 seconds (<time> 60 </ time> ) Is set. This indicates that the sensor condition CP is satisfied if the length of time for which the conditional expression is satisfied is 60 seconds or more.

  The sensor condition CI includes a conditional expression of value = 50 (<condition> == </ condition> and <value> 50 </ value>) and a time length of 5 seconds (<time> 5 </ time> ) Is set. This indicates that the sensor condition CM is satisfied if the length of time for which the conditional expression is satisfied is 5 seconds or more.

  In addition to the sensors shown in FIG. 2, there are sensors corresponding to a temperature sensor, a humidity sensor, an illuminance sensor, a timer that detects the current time, a human body sensor, and the like. The sensor condition of such a sensor describes the type of the sensor.

  FIG. 3 is a diagram illustrating control information. The control information is created, for example, in an XML language as shown in FIG. 3 by operating the input device.

  The control information Pg1 shown in FIG. 3 is a control content Pgl1 (<) that turns on the device D (referred to as light) whose identification information (id) is 1 among the devices D of the type (Type) as light. In the portion surrounded by event id = “2”> and </ event>, <device id = “1”>, </ device> and the portion surrounded by these tags) are set.

  The control content Pgl1 is surrounded by <event id = “1”> <state tf = “true”> and </ state> </ event>, and the condition for executing the control content Pgl1 is state information. It shows that the state of St1 is established.

  Next, the operation of the device control apparatus 1 will be described.

  Each sensor S in FIG. 1 performs detection on a detection target of detection performed by itself.

  The conversion unit 12 continuously obtains the result by waiting or polling the detection result. Then, the result is converted into a value, and the value is stored in a memory or the like.

  For example, if the character string “on” is acquired from the projector sensor when the room is in the room, these are converted to a value of 0, and if it is “off”, they are converted to 1, and these are stored in a memory or the like. Remember me. Also, for example, if a numerical value expressed by 1 digit below the decimal point of “50.0” is obtained from the illuminance sensor, it is converted into a value not expressed by the decimal point of 50 and stored in a memory or the like. .

  Such conversion is performed according to the method of expressing the detection result and the method of expressing the value in the conditional expression in the sensor condition of the state information. As another example, for example, the character string “27 degrees” as a result of detection by the temperature sensor is converted to a value “27.0”. Alternatively, the character string “12:10”, which is the result of detection by a timer that is a sensor that detects the current time, is converted to the value “1210.0”. Alternatively, the result when the human body cannot be detected by the human body sensor is converted to the value “0.0”, while the result when the human body is detected is converted to the value “1.0”.

  Next, the process of the sensor condition establishment determination unit 13 will be described.

  FIG. 4 is a flowchart of the sensor condition establishment determination unit 13. Here, the sensor condition CP of the state information St1 will be described as an example. In this case, the sensor condition satisfaction determination unit 13 measures the length of time.

  First, a value converted from the result of detection by the projector sensor is read from a memory or the like (S1). The sensor condition establishment determination unit 13 can acquire the type (Type) of the sensor (in this case, the projector sensor) corresponding to the value and the identification information (id) in the sensor S of that type. Next, the state information St1 in which the sensor condition CP including the type and the identification information is set is read from the state information storage unit 11, and it is determined whether or not the sensor condition CP is satisfied by the acquired value. (S3). That is, it is determined whether or not the conditional expression “value = 0” of the sensor condition CP is satisfied (S3). For example, if the value is 1 and it is determined as NO, it is determined whether or not the length of time is being measured (S5). If it is determined as NO, the sensor condition CP is at this time point. If it is not established (S7), the process returns to S1. If YES is determined in S5, the measurement of the length of time is terminated (S9), and the process proceeds to S7.

  If it is determined as YES in S3, it is determined whether or not the time length is being measured (S11). If it is determined as NO, measurement of the time length is started (S13). Return to S1.

  If YES is determined in S11, it is determined whether or not the length of time from the start of measurement is equal to or longer than the length of time (60 seconds) set in the sensor condition CP (S15). If NO is determined, the process returns to S1. If YES is determined, the sensor condition CP is assumed to be satisfied (S17), and the process returns to S1.

  The sensor condition establishment determination unit 13 performs the process of FIG. 4 in parallel for other sensor conditions, and stores success or failure of each sensor condition in a memory or the like.

  If the time length is not set in the sensor condition, it is determined whether or not the conditional expression is satisfied by the value. If the conditional expression is satisfied, the sensor condition is satisfied and the conditional expression is not satisfied. Then, the sensor condition is not satisfied. Even if an inequality sign is included in the conditional expression, the success or failure of the sensor condition may be determined by the success or failure of the conditional expression including the inequality sign.

  Next, processing of the state establishment determination unit 14 will be described.

  FIG. 5 is an example of a flowchart of the state establishment determination unit 14. The state establishment determination unit 14 analyzes the relationship between AND and OR between the sensor conditions in the state information, and determines the success or failure of the state of the state information with an algorithm according to the analysis result. Here, the state information St1 in which only the OR relationship is set will be described as an example.

  First, the success or failure of a certain sensor condition is read from a memory or the like (S21). The state establishment determination unit 14 can acquire the type (Type) and the identification information (id) (identification information in the sensor S of that type) included in the sensor condition corresponding to the success or failure. In addition, the state information St1 in which the sensor condition CP including the type and the identification information is set is read from the state information storage unit 11, the success or failure of another sensor condition CI is read, and at least one of the sensor condition CP and the sensor condition CI is read. It is determined whether the sensor condition is satisfied (S23). If it is determined as YES, the state of the state information St1 is established (S25), and the process returns to S1. When it is determined NO, it is determined that the state of the state information St1 is not established (S27), and the process returns to S1.

  The state establishment determination unit 14 performs the processing of FIG. 5 in parallel on other state information, and stores the result in a memory or the like in a manner as shown in FIG.

  Next, processing of the device control unit 15 will be described.

  First, the success or failure of the state of certain state information is read from a memory or the like. Next, if the success / failure indicates the establishment of the state, the control information in which the control content at that time is set is read from the control information storage unit 16, and the device D is controlled according to the control content. For example, control information including <event id = “1”> and </ event> indicating identification information indicating the state information St1 if the success or failure of the state of the state information St1 is acquired and indicates that the state is established. Pg1 is read and the control content Pgl1 set therein is executed. This automatically turns on the light when the room is in the room.

  Next, the process of the control content contradiction determining unit 17 will be described.

  FIG. 7 is a flowchart of the control content contradiction determining unit 17.

  First, two state information is read from a memory or the like, and a pair of sensor conditions in one state information and sensor conditions in the other state information, the type (Type) and the identification information (id) being the same. It is determined whether there is one or more (S31). When it is determined NO, it is determined that there is a possibility that the state of one state information and the state of the other state information may be established at the same time (S33).

  Next, although the case where it determines with YES is demonstrated, suppose that only the applicable sensor conditions are set to two state information here. Further, the state of each state information is established when all the sensor conditions in the state information are satisfied. In addition, the sensor condition of the other state information that is not one of the state information is included in one of the corresponding sets.

  First, in all of the corresponding sets, the value (or range of values) specified by “the conditional expressions of both sensor conditions are both equal and the same value” or “one conditional expression (equal expression or inequality)” is It is determined whether or not “included in the range of values defined by the other conditional expression (inequality expression)” is satisfied (S35). That is, in all the corresponding groups, when the sensor condition of one state information is satisfied, it is determined whether the sensor condition of the other state information is always satisfied.

  If it is determined YES in S35, it is determined that the state of the other state information is necessarily established when the state of one state information is established (S37). That is, it is determined that one state is included in the other state.

  If it is determined NO in S35, “the value (or range of values) defined by one conditional expression (equal expression or inequality) and the conditional expression (equal expression or inequality) of the other state information are defined. It is determined whether or not there is one or more corresponding sets that “there is no common part with the value (or value range)” (S39).

  When it is determined YES in S39, it is determined that the state of one state information and the state of the other state information are not established at the same time (S41).

  When it is determined NO in S39, it is determined that there is a possibility that the state of one state information and the state of the other state information may be established at the same time (S33).

  In addition, when the state of the other state information is established by the establishment of any one of the sensor conditions in the state information, the state information in which one of the sensor conditions is set is used instead of the other state information, The process of FIG. 7 is performed for each sensor condition, and when the process proceeds to S37 in any one of the processes, it may be determined that the state of the other state information is always satisfied when the state of one state information is satisfied.

  For example, the state information St2 of FIG. 8, that is, the sensor condition CP (<sensor id = “1”>, </ sensor> and a portion surrounded by these tags), and a type (Type) of a motion sensor (Motion Sensor). Sensor condition CM (<sensor id = “2”>) and </ value which is a condition of a value obtained by detection performed by sensor S (referred to as a motion sensor) having identification information (id) of 1 in S It is assumed that state information St2 in which “sensor> and a portion surrounded by these tags) is set is stored in the state information storage unit 11.

  The state information St2 indicates that the state of the state information St2 is satisfied when both the conditions are satisfied by surrounding the sensor condition CP and the sensor condition CM with <and id = “1”> and </ and>. .

  The sensor condition CM includes a conditional expression of value = 0 (<condition> == </ condition> and <value> 0 </ value>) and a time length of 10 seconds (<time> 10 </ time> ) Is set. This indicates that the sensor condition CM is satisfied if the length of time that the conditional expression is satisfied is 10 seconds or more.

  If one state information is the state information St2 and the other state information is the state information St1, the process of FIG. 7 is performed for the number of sensor conditions of the state information St1, and the process of the sensor condition CP returns to S37. Therefore, when the state of the state information St2 is established, it is determined that the state of the state information St1 is necessarily established.

  The control content contradiction determining unit 17 also performs the process of FIG. 7 for other combinations of state information, and stores control information for combinations of state information that are determined to always satisfy the other state when one state is satisfied. The control information corresponding to one state and the control information corresponding to the other state are read from the unit 16, and it is determined whether the control content of one control information and the control content of the other control information are inconsistent. To do.

  For example, in the control information Pg2 of FIG. 9, that is, the control content Pgl2 for turning off the light (<device id = “1”> and </ event>, <device id = “1”>) and </ It is assumed that control information Pg2 in which device> and a portion surrounded by these tags are set is stored in the control information storage unit 16.

  The control content Pgl2 is surrounded by <event id = “2”> <state tf = “true”> and </ state> </ event>, and the condition for executing the control content Pgl2 is state information. It shows that the state of St2 is established.

  In this case, when the state of the state information St2 is established, the control information Pg1 corresponding to the state information St1 is read for a combination (state information St1 and state information St2) that is determined to be necessarily established. Further, the control information Pg2 corresponding to the state information St2 is read out. Then, it is determined whether or not the control content Pgl1 of the control information Pg1 and the control content of the control information Pg2 contradict each other. Since the control content Pgl1 is the control content for turning on the light, and the control content Pgl2 is the control content for turning off the light, it is determined that there is a contradiction.

  In addition, as shown in FIG. 10, when both control contents are in the same control information, the control information may be read and it may be determined whether or not the control contents in the control information contradict each other.

  If it is determined that the control details are inconsistent, the user is notified of this, and either one of them is set to be executed with priority, or one is deleted, or both are reset. Alternatively, it is preferable to adopt a configuration in which execution of the control content is stopped.

  Now, the illuminance sensor is changed to another illuminance sensor, and as a result, the conditional expression (value = 50) of the sensor condition CI set in the state information St1 is not suitable for the changed illuminance sensor, and the above-described room exists. If the light is not turned on automatically in the room, the state information St1 is deleted from the state information storage unit 11, and a sensor condition having a conditional expression suitable for the changed illuminance sensor is set. The state information is generated and stored in the state information storage unit 11 so that the light can be correctly controlled. Further, even when a new sensor is added, by storing the state information for the sensor in the state information storage unit 11, correct device control can be performed. Therefore, it is not necessary to change the computer program itself for operating the device control apparatus 1 or replace the apparatus.

  In the present embodiment, the sensor condition establishment determination unit 13, the state establishment determination unit 14, and the control content contradiction determination unit 17 read the state information from the state information storage unit 11. A management unit may be provided, and the management unit may provide the sensor condition establishment determination unit 13 or the like with state information read by a request from the sensor condition establishment determination unit 13 or the like.

  In the present embodiment, the device control unit 15 and the control content contradiction determination unit 17 read out the control information from the control information storage unit 16, but the management unit of the control information storage unit 16 is provided, and the management unit However, the control information read by the device control unit 15 or the like may be given to the device control unit 15 or the like.

  Further, the control content contradiction determining unit 17 may determine whether or not the state of the other state information is always established when the state of one of the state information is established by an algorithm other than the above. That is, an algorithm corresponding to the setting of AND or OR in the sensor condition in the state information may be adopted.

  As described above, according to the device control apparatus 1 according to the present embodiment, the state serving as the state information storage unit stores the state information in which the sensor condition, which is the condition of the value obtained by the detection performed by the sensor, is stored. Sensor condition as sensor condition establishment determination means for determining whether or not the sensor condition of the state information read from the state information storage unit 11 is satisfied based on the information storage unit 11 and the value obtained by the detection performed by the sensor The establishment determination unit 13, the state establishment determination unit 14 serving as a state establishment determination unit that determines whether the state defined by the state information is established based on the determination result obtained by the determination, and obtained by the determination Device control unit 15 that is a device control means for controlling the device according to the determination result, the sensor information before the change in the state information storage unit 11 when the sensor is changed or added. By changing the status information to the status information for the sensor after the change, or by creating and storing the status information for the added sensor, correct device control can be performed. It is possible to reduce the time and effort without affecting the change of the program to be executed and the replacement of the device.

  Further, the control information storage unit 16 serving as a control information storage unit that stores control information in which the control content when the state determined by the state establishment determination unit 14 is established is stored, and the state information storage unit 11 are By reading the status information and determining whether or not the sensor condition of the other status information is satisfied when the sensor condition of one status information is satisfied, when the status condition of one status information is satisfied, the status information of the other When one state is established, if it is determined that the other state is necessarily established, the control information storage unit 16 obtains the control contents when the one state is established. Read out the control information including the control information when the other state is established or the control information including both control contents and whether both control contents contradict each other Because and a determining control contents conflict determination unit serving control content contradiction judging unit 17 whether it is possible to detect the inconsistency of control content.

  It should be noted that the control content contradiction is determined not only when it is determined that the other state is always established when one state is established, but in this case, the state of one state information and the state of the other state information are simultaneously determined. The determination may be made in both cases where it is determined that there is a possibility of being established (when the determination in S33 is performed).

  In the case where it is already verified that there is no contradiction in the control contents, the control content contradiction determination unit 17 may not be provided.

  Further, since the state establishment determination unit 14 determines whether or not the state has been established by combining the determination results of the plurality of sensor conditions, control according to the plurality of detection target states can be performed.

  The sensor condition establishment determining unit 13 measures the length of time that the conditional expression set in the sensor condition is established, and the measured time length is the length of time set in the sensor condition. Since it is determined whether the sensor condition is satisfied when it is determined whether or not it is equal to or longer than the length of the time, it is not surprising if a short-time change occurs in the result of detection by the sensor. It is possible to prevent inconvenience that the device is controlled. That is, the device can be controlled only when a desired detection result is obtained for a long time.

  Note that a computer program that causes the device control apparatus 1 to execute the operation method performed by the device control apparatus 1 in the present embodiment is a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, or a magnetic tape. The computer program may be stored and distributed for display, or the computer program may be transmitted via a communication network such as the Internet.

  Further, although the present embodiment has been described assuming that the device control apparatus is used in a single service, the apparatus may be used in a plurality of services. That is, the success or failure of the state obtained by the device control apparatus may be shared by a plurality of services.

  Moreover, you may utilize the success or failure of a state with a control apparatus as described in the following references 1 and 2. Such a control device accumulates operation performed on the service providing device as operation history in association with the environmental information to be monitored by the service providing device, and based on the operation history according to the change of the environment information, It controls a plurality of service providing devices. That is, by treating the success / failure of the state as environmental information, it is possible to change or add a sensor without correcting a program for operating the control device or correcting an operation history.
