The server 400, for example, provides general content to a person who has not introduced (used) the control device 200, and includes information obtained from the control device 200 to a person who uses the control device 200. May provide special content.

FIG. 6 is a diagram showing a configuration example of the server 400 in the information providing system 10 according to the present embodiment. The information terminal 300 and the network 31 are added to the figure.

As shown in FIG. 6, the server 400 includes a receiving unit 410, a transmitting unit 420, a communication unit 430, and an authentication unit 440.

The receiving unit 410 is composed of a communication circuit and has a function of receiving request information requesting information from the information terminal 300. In the information terminal 300, the communication unit 310 transmits the request information to the server 400 in response to the user operation detected by the detection unit 330. The request information includes, for example, information for identifying the address of the information terminal 300 (for example, an IP address, etc.). The request information includes information that requests energy management information (measurement result of power consumption in facility 20 and the like) (predetermined request information) and the like.

The communication unit 430 is composed of a communication circuit, and when the control device 200 is installed in the facility 20, it can communicate with the control device 200 via the network 31 and the router 30 (see FIG. 1) of the facility 20.

The authentication unit 440 is realized by, for example, a processor that executes a program, and has a function of authenticating the control device 200 installed in the facility 20 via the communication unit 430. It is assumed that the authentication is successful when the predetermined conditions are satisfied in order to confirm that the communication path (logical connection) for transmitting information between the server 400 and the control device 200 is established. If the conditions are not met, it is treated as not successful in authentication. For example, when the information transmitted between the control device 200 and the server 400 is protected by cryptographic communication technology, a logical connection is established by sharing the key according to a predetermined authentication procedure. To do. If the control device 200 is not installed in the facility 20, the authentication unit 440 does not succeed in authenticating the control device 200. When the control device 200 is introduced into the facility 20 and appropriately set, the authentication of the control device 200 by the authentication unit 440 becomes successful. In the authentication, for example, it is a condition of successful authentication that the predetermined request information received by the receiving unit 410 of the server 400 includes the predetermined authentication information. That is, the authentication unit 440 authenticates by communicating with the control device 200 using the predetermined authentication information via the communication unit 430. The predetermined authentication information may be the information itself required for communication with the control device 200 and the authentication of the control device 200 in the server 400, or may be information used for specifying the necessary information. The predetermined authentication information is, for example, an authentication code set in the control device 200 or the like. If the predetermined request information does not include the predetermined authentication information, the authentication unit 440 treats that the authentication is not successful. When the authentication unit 440 has succeeded in authenticating the control device 200, the communication unit 430 can receive consumption information and the like related to the power consumption of the facility 20 from the control device 200.

The transmission unit 420 is configured by, for example, the same communication circuit as the reception unit 410, and has a function of transmitting information (for example, information related to a web page to be displayed by the browser function of the information terminal 300) to the information terminal 300. .. For example, when the authentication unit 440 succeeds in authenticating the control device 200, the transmission unit 420 does not transmit the control information to the information terminal 300, and the authentication unit 440 does not succeed in the authentication of the control device 200. The control information is transmitted to the information terminal 300. The control information is transmitted, for example, included in the information related to the web page. The control information is the same as that described in the first embodiment, and is the information for presenting the information recommending the introduction of the control device 200 into the facility 20. Similar to the first embodiment, the control information may include information indicating the function of the control device 200. The transmission unit 420 transmits information (for example, information related to a web page including control information and the like) to the information terminal 300 with the address specified based on the predetermined request information received by the reception unit 410 as the transmission destination. .. Further, when the authentication unit 440 succeeds in authenticating the control device 200, the transmission unit 420 relates to, for example, consumption information received from the control device 200 by the communication unit 430 (for example, a web page including the consumption information). Information) can be transmitted to the information terminal 300 with the address specified based on the predetermined request information as the transmission destination. Further, when the authentication unit 440 has not succeeded in (or has succeeded in) authenticating the control device 200, the transmission unit 420 provides, for example, information related to a web page including product information of various products or other information. Can be transmitted to the information terminal 300 with the address specified based on the predetermined request information as the transmission destination. In the information terminal 300, the display unit 320 displays information (for example, a screen representing a web page) on the display device based on the information received from the server 400 by the communication unit 310.

(Step S34). The predetermined request information is, for example, information obtained by adding an IP address or the like of the information terminal 300 to a predetermined command.

When the server 400 receives the predetermined request information by the receiving unit 410, the server 400 authenticates the control device 200 by the authentication unit 440 (step S35). However, if the control device 200 is not installed, the authentication fails because the communication with the control device 200 cannot be performed. If the authentication fails, the server 400 uses the transmission unit 420 to send the information related to the web page representing the information recommending the introduction of the control device 200 to the destination specified by the IP address or the like included in the predetermined request information, that is, the predetermined destination. It is transmitted to the information terminal 300 that is the source of the request information (step S36).

The information terminal 300 receives information related to a web page representing information for which the introduction of the control device 200 is recommended by the communication unit 310, and displays the screen of the web page based on the received information on the display device by the display unit 320. (Step S37). As a result, the user can know that the control device 200 can be introduced. The information recommending the introduction of the control device 200 is the same as that shown in the first embodiment, and may be information indicating a method of introducing the control device 200, advantages of introduction, a function of the control device 200, and the like. ..

When the authentication unit of the device 200, etc.) succeeds in authenticating the control device 200, the information terminal 300 is authenticated without transmitting the control information for presenting the information recommending the introduction of the control device 200. A transmission unit (transmission unit 420 or transmission unit 130) that transmits control information to the information terminal 300 when the unit has not succeeded in authenticating the control device 200 is provided. The introduction of the control device 200 is an introduction to the information providing system 10, for example, an introduction to the facility 20. With this introduction, the control device 200 can communicate with the devices constituting the information providing system 10.

With this configuration, the introduction of the control device 200 into the facility 20 can be promoted. Further, the control device 200 can suppress energy consumption such as electric power.

(2) For example, the information providing system 10 further includes a receiving unit (reception unit 410 or 120) that receives predetermined request information including information for specifying the address of the information terminal 300 from the information terminal 300. The transmitting unit may transmit the control information to the information terminal 300 with the address specified based on the predetermined request information received by the receiving unit as the transmission destination. The information for specifying the address may be an address, or information for specifying the address by a correspondence table, arithmetic processing, etc. (for example, user identification associated with the address in the registration table, etc. by user registration in advance). Information, etc.).

As a result, the information providing system 10 can provide control information for recommending the introduction of the control device 200 in response to the access from the information terminal 300.

(3) For example, the control device 200 has a function of acquiring the measurement result of energy consumption in the facility where the control device 200 is installed and holding the consumption information generated based on the measurement result, and the information providing system 10 has a function. Further, when the authentication unit 440 (or the authentication unit 150 or the like) succeeds in authenticating the control device 200, the communication unit 430 (or the communication unit 140) for receiving consumption information from the control device 200 is provided, and the transmission unit 420 is provided. (Or, if the authentication unit 440 (or the authentication unit 150, etc.) succeeds in authenticating the control device 200, the transmission unit 130 is based on the predetermined request information received by the reception unit 410 (or the reception unit 120). The consumption information received by the communication unit 430 (or the communication unit 140) may be transmitted to the information terminal 300 using the specified address as the transmission destination.

As a result, when the control device 200 is installed in the facility 20, the user can know the information on the energy consumption by the information terminal 300.

(4) For example, the transmission unit 420 transmits the consumption information to the information terminal 300 on the condition that the predetermined request information received by the reception unit 410 includes the predetermined authentication information (for example, an authentication code), and the reception unit 420. If the predetermined request information received by the 410 does not include the predetermined authentication information, it is considered that the authentication by the authentication unit 440 has not succeeded, and the control information (information for recommending the introduction of the control device 200) to the information terminal 300. ) May be sent. The predetermined authentication information may be directly used for the authentication of the control device 200, or the information for specifying the information used for the authentication of the control device 200 (for specifying by a predetermined correspondence table, arithmetic processing, etc.). Information).

As a result, the information providing system 10 provides the consumption information related to energy consumption to the information terminal 300 when the predetermined authentication information such as the authentication code is input, and when the predetermined authentication information is not input, the control device 200 Can provide information to promote the introduction of.

(5) For example, the information providing system 10 is a measuring device installed in the facility 20 and includes a measuring unit 110, an authentication unit 150, a transmitting unit 130, and a receiving unit 120 for measuring the power consumption of the facility 20. It may be provided with 100.

(6) For example, the transmission unit 130 may transmit the measurement result by the measurement unit 110 to the information terminal 300.

As a result, the information terminal 300 can receive information related to power consumption from the measuring device 100 of the facility 20, and when the measuring device 100 is accessed for receiving this information, the control device 200 is not installed in the facility 20. Information about the control device 200 can be received from the measuring device 100.

(7) For example, the authentication unit 150 certifies the control device 200 installed in the facility 20 in which the measuring device 100 is installed, and the measuring device 100 has succeeded in certifying the control device 200 by the authentication unit 150. In this case, the communication unit 140 is provided to transmit the measurement result by the measurement unit 110 to the control device 200, and the control device 200 communicates with the device (for example, the measurement device 100, the device 21, etc.) in the facility 20 in which the control device 200 is installed. By doing so, it has a function of acquiring the measurement result of power consumption and holding the consumption information generated based on the measurement result, and the information providing system 10 further receives the consumption information from the control device 200 and informs the consumption information. A server 400 for transmitting to the terminal 300 may be provided. The consumption information may be transmitted in response to an access from the information terminal 300, or may be performed by a communication method such as e-mail.

As a result, wherever the information terminal 300 can receive information from the server 400, the control device 200 of the facility 20 can be moved from the server 400 when the control device 200 is installed in the facility 20. It becomes possible to receive the consumption information generated based on the information related to the power consumption.

(8) For example, when the authentication unit 150 succeeds in authenticating the control device 200, the transmission unit 130 provides an information terminal with a computer program (for example, an application program) for receiving and displaying consumption information from the server 400. Information used for the 300 to acquire (for example, information on the website to which the program is downloaded) may be transmitted to the information terminal 300. An application program for receiving and displaying consumption information from the server 400 is, for example, a method of communicating a signal (consumption information) with the server 400 so that the server 400 can receive and display the consumption information in response to transmitting the consumption information. And the expression method etc. are matched.

As a result, the information terminal 300 can acquire and install the application program, so that the information terminal 300 can appropriately acquire consumption information by accessing the server 400, for example, with the application program.

(9) For example, the measuring device 100 may be located in the housing of the distribution board.

As a result, it is relatively easy for the measuring device 100 to separately measure the electric power or the amount of electric power consumed in the facility 20 by providing a current sensor for each branch circuit in the distribution board, for example. it can. Therefore, the measuring device 100 can provide useful information related to power consumption to the information terminal 300 and the like.

(10) For example, the control information (information for recommending the introduction of the control device 200) includes the content of the information recommending the introduction of the control device 200 or the presentation instruction of the information recommending the introduction of the control device 200. It may be that.

As a result, the information terminal 300 that has received the control information can present information that recommends the introduction of the control device 200. Therefore, the user can know the control device 200.

(11) For example, the control information may include information indicating the function of the control device 200.

As a result, the information terminal 300 that has received the control information can present information indicating the function of the control device 200. Therefore, the user can know the function of the control device 200.

(12) The information display method according to one aspect of the present invention is a control having a function of generating consumption information based on the measurement result of energy consumption in the facility 20 in which the control device 200 is installed in the display device provided in the information terminal 300.
