  The terminal device 200 is typically a mobile phone or PDA (Personal Digital Assistant) carried by the user. As shown in FIG. 7, the terminal device 200 includes a terminal control unit 201, a terminal storage unit 202, a terminal input unit 203, a terminal display unit 204, and a terminal communication unit 205.

  The terminal control unit 201 includes, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), various drivers, and the like. The terminal control unit 201 controls each unit of the terminal device 200 and is stored in the terminal storage unit 202. Each process to be described later is executed based on the operation program.

  The terminal storage unit 202 is configured by a predetermined storage device such as a ROM (Read Only Memory) or a flash memory, for example. In addition to an operation program (application) executed by the terminal control unit 201, data necessary for executing each process Or data acquired or generated by execution of each process.

  The terminal communication unit 205 includes an interface for performing wireless communication, and wirelessly communicates with the information providing apparatus 100 in accordance with a predetermined protocol.

  Subsequently, the operation of the information providing apparatus 100 will be described. The processing executed by the information providing apparatus 100 is broadly classified into a current information providing process performed in the normal mode and an expected information providing process performed in the prediction mode. First, the current information providing process will be described with reference to the flowchart of FIG. As a premise, it is assumed that the operation mode of the information providing apparatus 100 is set to the normal mode. In addition, it is assumed that the environment storage unit 105 and the power consumption storage unit 107 store and store information indicating the environment of each room R1 to Rn and the power consumption of the device 300, respectively.

  When the predetermined time has elapsed, or when the communication unit 102 receives a request for information acquisition from the terminal device 200 (step S101; Yes), the room detection unit 103 is located in which room in the building the terminal device 200 is located. Is determined (step S102).

  Subsequently, the current information acquisition unit 108 stores the information indicating the current environment of the determined room R and the information indicating the current power usage of the device 300 installed in the room R with the environment storage unit 105 and the power usage memory. Each is acquired from the unit 107 (step S103). For example, when it is determined that the terminal device 200 is located in “room R1”, the current information acquisition unit 108 is “room R1” among the environments of the rooms R1 to Rn stored in the environment storage unit 105. And, the latest one is acquired as the current environment. Further, the current information acquisition unit 108 is “room R1” among the power consumption amounts of the devices 300 in the rooms R1 to Rn stored in the power consumption storage unit 107, and the latest one is the current one. Acquired as the amount of power used by the device 300.

  Subsequently, the current information acquisition unit 108 creates current status display data for causing the terminal device 200 to display the acquired information as a graph or the like (step S104). When it is desired to display the room name and the type of the device 300, the current information acquisition unit 108 may acquire the corresponding room name and the type of the device 300 from the fixed information storage unit 101.

  Subsequently, the communication unit 102 transmits the created display data to the terminal device 200 (step S105).

  When the terminal communication unit 205 of the terminal device 200 receives the current status display data from the information providing device 100, the terminal control unit 201 causes the terminal display unit 204 to display the received display data. FIG. 9 shows an example of a screen displayed on the terminal display unit 204. On this screen, the environmental information (room temperature, humidity) of the room R1 is displayed as text at the top, and the power consumption of the device 300 (air conditioner, lighting) is displayed as a bar graph. This display example is merely an example, and the amount of power used may be displayed as a pie chart or a line graph, or all information may be displayed as text. This is the end of the current information providing process.

  Next, the prediction information providing process will be described with reference to the flowchart of FIG. As a premise, it is assumed that the operation mode of the information providing apparatus 100 is set to the prediction mode. In addition, the environment storage unit 105, the power usage storage unit 107, and the operation status storage unit 110 store information indicating the environment of each room R1 to Rn, the power consumption of the device 300, and the operation status of the device 300, respectively. It shall be remembered.

  When the predetermined time has elapsed or when the communication unit 102 receives a request for information acquisition from the terminal device 200 (step S201), the room detection unit 103 is located in which room in the building the terminal device 200 is located. (Step S202).

  Subsequently, the power consumption prediction unit 111 includes information indicating the environment in the room associated with the room number of the determined room, information indicating the power consumption of the device 300 in the room, Among the information indicating the operation state of the device 300, information (history information) for a predetermined period from the latest information is acquired from the environment storage unit 105, the used power storage unit 107, and the operation status storage unit 110, respectively (step S203). ).

  Subsequently, the power consumption prediction unit 111 predicts the power consumption after a predetermined time (for example, 3 hours later) of the device 300 in the room determined in Step S202 from the acquired history information (Step S204).

  Specifically, the power consumption predicting unit 111 obtains the average daily power consumption transition or the transition of the previous day power consumption from the acquired power consumption history, and follows the transition to determine the power consumption. Is assumed to change, and the amount of power after a predetermined time may be predicted. For example, when the daily power consumption is calculated to show a transition as shown by the dotted line in FIG. 11 and the current power consumption is P1, the subsequent power consumption changes along the dotted line in the figure. The amount of power used after a predetermined time is estimated to be P2. Note that the power amount after a predetermined time may be predicted on the assumption that the slope of the change in the power amount at the current time is obtained from the acquired history of the used power amount, and that the future power amount changes along this slope.

  In addition, the power usage prediction unit 111 determines the trend of the operation state of the device 300 for one day (for example, the time zone in which the device is mainly operated in one day, To find out when it will be stopped. Thereafter, the power usage prediction unit 111 predicts the operating state of the device 300 after a predetermined time based on this tendency, and determines the power amount when the device 300 is operated in the predicted operating state as the power amount after the predetermined time. You may expect.

  Subsequently, the power usage prediction unit 111 creates prediction result display data for displaying the prediction result on the terminal device 200 in a graph or the like (step S205). At this time, when it is desired to display the room name of the target room, the name of the device 300, and the like, the power consumption prediction unit 111 acquires the corresponding room name, the name of the device 300, etc. from the fixed information storage unit 101. That's fine.

  Subsequently, the communication unit 102 transmits the created prediction result display data to the terminal device 200 (step S206).

  When the terminal communication unit 205 of the terminal device 200 receives the predicted result display data from the information providing apparatus 100, the terminal control unit 201 causes the terminal display unit 204 to display the received predicted result display data. FIG. 12 shows an example of a screen displayed on the terminal display unit 204. On this screen, the current value of the power consumption of the device 300 (air conditioner, lighting) and the predicted value after 3 hours are displayed as a bar graph. Thus, the power consumption prediction process ends.

  As described above, in the present invention, when various types of information regarding a building are provided to the terminal device 200, the room (area) where the terminal device 200 is located is specified, and the information corresponding to the specified room is selected to be the terminal device. 200. Therefore, it is possible to display information with high real space. Further, in the present invention, since the power used by the device 300 can be predicted and displayed from the environment in the specified space and the history of the operating state of the device 300, it is excellent in real time in addition to real space. It is also possible to display.

  Moreover, according to these structures, the information provision apparatus 100 is in the room (area) discriminated based on the position confirmation signal and the room number (area identification information) received from the terminal apparatus 200 possessed by the user. Information indicating the amount of power used by each of the arranged devices 300 is transmitted to the terminal device 200. For this reason, the information which shows the electric power consumption of the apparatus 300 according to a user's position can be provided. Therefore, when the terminal device 200 displays information indicating the amount of power used by the device 300 according to the position of the user, real space and reality appear in the display content of the terminal device 200 for the user. Further, if the user moves the position and changes the room, the information transmitted from the information providing apparatus 100 to the terminal apparatus 200 changes, so the power consumption displayed by the terminal apparatus 200 also changes. For this reason, since the user continues to feel freshness in the displayed content even after a while, the user is not bored with the displayed content. Therefore, the user effectively uses the amount of power used displayed on the terminal device 200 and suppresses unnecessary power consumption, thereby realizing energy saving.

  Furthermore, according to these configurations, the power consumption after a predetermined time is predicted based on the tendency of the power consumption of the device 300 arranged in the determined room (area) over time. For this reason, the electric power consumption of the apparatus 300 after predetermined time can be estimated accurately.

  Moreover, according to these structures, the electric power consumption after predetermined time is estimated based on the tendency of the time change of the driving | running state of the apparatus 300 arrange | positioned at the discriminate | determined room (area). For this reason, the electric power consumption of the apparatus 300 after predetermined time can be estimated accurately.

  Furthermore, according to these configurations, in order to transmit the information indicating the predicted value of the predicted power consumption to the terminal device 200, the information indicating the predicted value of the power consumption of the device 300 according to the position of the user is provided. it can. Therefore, when the terminal device 200 displays information indicating the predicted value of the power consumption of the device 300 according to the user's position, for example, the user's position because the user does not perform an action for realizing energy saving. If the usage status of the device 300 corresponding to the change does not change, it becomes clear to the user what value the power consumption will be after a predetermined time. For this reason, the reality of the user with respect to the amount of power used after a predetermined time is improved. Therefore, it is possible to specifically prompt the user to analyze the energy consumption status, find a point to be improved regarding energy use, and take specific action for the improvement.

  According to these configurations, since the information indicating the environment of the determined area is transmitted to the terminal device 200, the information indicating the user environment can be provided to the terminal device 200. Therefore, when the terminal device 200 displays information indicating the user's environment, for example, the user suppresses the power consumption based on the displayed environment and the amount of power used to realize the environment. It can be easily determined whether or not to do so. For example, the reality of the user with respect to an increase in the amount of power used for reducing the temperature of a room where the user is located to a predetermined temperature is improved. For this reason, the user can easily take specific actions necessary for energy saving.

  In addition, this invention is not limited to the said embodiment, Of course, the various change in the range which does not deviate from the summary of this invention is possible.

  For example, information provided (transmitted) to the terminal device 200 by the information providing apparatus 100 is arbitrary. In the above embodiment, in the normal mode, the current environment of the room where the terminal device 200 is located and the current power consumption of the device 300 arranged in the room are acquired, and the acquired information is displayed. Current status display data for the user is created and transmitted to the terminal device 200. However, the information providing apparatus 100 may directly transmit the acquired information to the terminal apparatus 200 and process and display the data on the terminal apparatus 200 for display.

  In addition, the information providing apparatus 100 may acquire only the used power amount and transmit it to the terminal apparatus 200 in the normal mode. Alternatively, the amount of power used may be converted into an electricity bill or carbon dioxide emission, and the converted information may be transmitted to the terminal device 200. Further, in addition to the current environment of the room in which the terminal device 200 is located and the power consumption of the device 300, information indicating the environment of the room for the past predetermined period (for example, for one week) and the power consumption of the device 300 May be acquired from the environment storage unit 105 and the power consumption storage unit 107, respectively, and transmitted to the terminal device 200 together with the current information.

  In addition, in each of the rooms R1 to Rn of the building, a communication master device that can communicate only within the room (for example, infrared communication, communication by weak radio waves, visible light communication) is installed, and the communication master device is connected via the communication master device. When the information providing apparatus receives a radio wave from the communication terminal 200, the room detection unit 103 may detect the room by assuming that the communication terminal 200 is located in a room corresponding to the communication parent device.

  Further, the type of the environmental measurement sensor 500 that is connected to the information providing apparatus 100 according to the present invention and notifies the detection result is not limited, and may be a temperature sensor, a humidity sensor, an illuminance sensor, an infrared sensor, a carbon dioxide sensor, or the like. May be.

  In addition, for example, by applying an operation program that defines the operation of the information providing apparatus 100 according to the present invention to an existing personal computer, an information terminal device, or the like, the personal computer or the like functions as the information providing apparatus 100 according to the present invention. It is also possible to make it.

  Further, the distribution method of such a program is arbitrary. For example, the program can be read by a computer such as a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), an MO (Magneto Optical Disk), or a memory card.
