Description

  The present invention relates to an air conditioning control system.

  In recent years, social demands for energy conservation due to global warming are increasing. The current energy conservation law obliges the consumer sector not only to improve the energy conservation performance of individual devices, but also to conserve energy in terms of management using BEMS (Building and Energy Management System).

  However, as the actual situation of building management, the building manager does not always operate air conditioning devices such as cooling and heating appropriately from the viewpoint of comfort and energy saving. In particular, with regard to thermal environment management (for example, temperature management) of living spaces where energy saving and comfort are intricately related, a customary target temperature is set for ease of management, and it is received from users who enjoy the thermal environment. Generally, the set value is changed according to a claim.

  In other words, because temperature management is performed without fully considering the characteristics of the building or occupants, the living space is not necessarily kept in a comfortable state for the user, and furthermore, waste of energy consumed by the air conditioner occurs. There is. In addition, some users are dissatisfied with being unable to control their own thermal environment because they are in a thermal environment managed by the building manager.

In response to the problems caused by temperature management of air conditioning control, users' requests for thermal environment are collected in real time from personal computer terminals (hereinafter referred to as personal computers) operated by each individual. There is a method to set the target temperature based on the relationship between the thermal environment desired by the user and the target temperature in real time, the user characteristics that change from moment to moment, the difference between the actual temperature of the living space and the detected temperature, etc. It is possible to change the thermal environment according to the characteristics of each building. (For example, refer to Patent Document 1).

  By the way, the air-conditioning control using the user's request can be efficiently operated by using information such as the user, location, and sex. For example, it is possible to perform air-conditioning control without being influenced by a request from a user with a high input frequency by determining the request from the same user based on the identification information. However, this requires labor for registering the user's personal information (name, gender, location, etc.) in the server device, and further labor is required to update the personal information.

  By the way, with the spread of the Internet in recent years, the equipment industry is also accelerating the use of WEB for equipment controllers. To access the WEB server in the equipment controller, it is necessary to verify that it is a registered user by comparing the user name of the access source with the user name registered in the WEB server, The authentication method is well known. This authentication is performed for the purpose of restricting access and users in order to construct a robust security system for the equipment system.

  In addition, in the entrance / exit management system, the personal information registered in the personal card is read by the card reading terminal and collated with the personal information stored in the server to manage the entrance / exit persons. .

  In addition, even in a WEB service that provides a dedicated page for each individual on the WEB server and provides a service for each individual, authentication is performed by checking the user name and the user name registered in the WEB server. Yes. In particular, since a WEB server existing on the Internet is accessed anonymously by an unspecified number of WEB users, robustness of personal information security is required as a social background.

  Thus, the authentication method in the WEB server is becoming normal from the viewpoint of personal information protection, and this is influenced by social trends such as the Personal Information Protection Law.

  However, as in the air conditioning control system of the above-mentioned Patent Document 1, a request is made for the temperature to be raised, the temperature is to be lowered, and the service status is displayed on the user side. As shown in FIG. 2, personal information is registered in advance in the database 201a of the server 201, identification information is transmitted from each user's personal computer 202, and the server 201 stores the identification information transmitted from the personal computer 202 in the server 201. Adopting an authentication method that collates with registered personal information must be said to be excessive security. The provision of personalized services and the use of personal information performed by such air conditioning systems are related to the user characteristics (especially gender, age, location) necessary to properly control the indoor thermal environment, and further acquisition of requests. Sometimes it is necessary to identify whether or not it is the same person as the person who has already requested, and it does not require "identification of a specific person" that is the subject of the Personal Information Protection Law. As described above, registering a large number of personal information in the server for information that does not require a high level of security is considered to be a waste of registration man-hours.

  In addition, a method of registering information by the user is conceivable, but many users generally do not update the registered information once and do not delete it when it becomes unnecessary. Therefore, when a department is moved or the service is no longer used, unnecessary information remains on the server, and if control is performed based on this unnecessary information, the control becomes inappropriate. It is expected that. Furthermore, it cannot cope with the recent free address type office form.

  Thus, in the air conditioning control system, only “user characteristics related to air conditioning control” are required, but not “identification of specific individuals”, so a large number of personal information is registered in the server. The implementation of the personal authentication method is an excessive specification, and there is a problem that a large amount of man-hours are required for information registration.

  The present invention has been made in view of the above-described reasons, and its object is to provide an air conditioning control system that can suppress the registration cost of user information, and can prevent misuse of information, not excessive specifications. It is in.

According to the first aspect of the present invention, there is provided an air conditioning equipment that varies the temperature of a space to be air-conditioned, an air conditioning controller that controls the operation of the air conditioning equipment based on the target temperature, and a central control that sets a target temperature in the air conditioning controller. And an input device that provides request information on the temperature of the space input from a user existing in the space to the central control device together with identification information consisting of personal information for identifying the user. Request information acquisition means for acquiring request information from the input device together with identification information, request temporary storage means for storing the request information acquired by the request information acquisition means in association with the identification information, and the target based on the request information A demand information acquisition means including a control plan deriving means for deriving a temperature, and the demand information acquisition means is added with the same identification information as the identification information already stored in the demand temporary storage means If acquired, the request information already stored in association with the identification information is deleted, and the request temporary storage means deletes the identification information associated with the request information after a predetermined time from storing the request information. It is characterized by doing.

  According to the present invention, since it is possible to identify users without registering a large number of user identification information in the central control device, a large number of identification information is registered in the central control device instead of overspecs. Compared to the personal authentication method, the registration cost of identification information can be suppressed. Furthermore, there is no identification information that is user information in the central control unit, and the information is not abused.

  According to a second aspect of the present invention, in the first aspect, the input unit includes a request history storage unit that stores a history of input request information, and transmits a feedback request together with the request information history and the identification information to the central control unit. When the central control unit receives the feedback request together with the control history storage means for storing the control history of the target temperature and the request information history and the identification information, the content of the request information history is based on the request information history and the control history. It is characterized by comprising feedback information generating means for determining whether or not it has been realized and returning the determination result to the input device that is the transmission source of the feedback request.

  According to this invention, it is possible to confirm whether or not the user's request has been realized.

  As described above, there is an effect that the registration cost of the user's information can be suppressed and the abuse of the information can be prevented, not the excessive specification.

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

(Embodiment)
FIG. 1 shows a configuration of an air conditioning control system according to the present embodiment, in which one or a plurality of users exist and a thermal environment is constructed by the system (for example, a floor in a building, each room, or a wide area). Public area) On the air conditioning equipment 1 and air conditioning control device 2 installed in A, and on a communication network NT (Ethernet (registered trademark), etc.) in which each user in the space A inputs desired information on the temperature of the space A A central control device that connects a plurality of input devices 3 composed of personal computer terminals to each input device 3 via a communication network NT, and sets a target temperature To of space A based on desired information input by each user. (Hereinafter referred to as a server device) 4.

  The input device 3 includes an information input unit 31, a request history storage unit 33, and a display unit 34. When each input device 3 inputs desired information, the air conditioning number of the target air conditioning equipment 1 (number specifying the air conditioning area of the air conditioning equipment 1) and unique identification information (for example, an individual name or Identification information and an air conditioning number are added when request information and the like are transmitted on the communication network NT. Alternatively, the identification information is stored in identification information storage means (not shown) by reading personal information (ID number, gender, age, location, etc.) registered in an ID card carried by the user. But you can.

  The server device 4 receives request information from the input device 3 together with the identification information and the air conditioning number via the communication network NT, and a request temporary storage for storing the request information in association with the identification information and the air conditioning number. Based on the means 42 and the desired information, the target temperature To of the space A is derived based on the total content and the judgment criteria registered in the judgment criteria database 43, and the communication network NT is connected to the air conditioning control device 2. Control plan drafting means 44 passed through, control history storage means 45 for storing the history of the target temperature To, and feedback information generating means 46 for generating feedback information in response to a feedback request from the input device 3.

  As shown in FIG. 2A, the air conditioning equipment 1 used in the system of the present embodiment is installed in the air conditioning equipment room 100 in the form of cold / hot water from a heat source (not shown) consisting of a refrigerator (cooling tower) or boiler. It consists of an air conditioner consisting of an installed air conditioner 101, a duct 102 disposed in the space A, and an outlet 104, and heats and cools air (heat exchange with air) in the air conditioner 101, The heat-exchanged air is supplied into the space A from the dozen or more outlets 104 provided in the space A that is the floor of the environment control target through the duct 102. As for the return air, an air conditioner is used that secures a return air path 105 indicated by a broken line from the central passage of the space A toward the air conditioning equipment room 100, mixes the outside air at the same time, and performs air conditioning. In this air conditioning equipment, the air conditioner 101 changes the supply air temperature and controls the room temperature.

  Here, the thermal environment control target space A of the present embodiment is an office floor, for example, and a large number of desks 106 are arranged in the space A as shown in FIG. It has come to be used. In such a space A, the input device 3 which is a personal computer on the desk used by the user who enjoys the thermal environment accesses a WEB server (not shown) in the server device 4 and inputs content for inputting environmental information to the WEB. The information input means 31 is realized by obtaining from the server. In the illustrated example, it is assumed that a system capable of communicating with the server device 4 is constructed for all the input devices 3 via the communication network NT, and information input means 31 is provided between the server device 4 and the input device 3. Realized software runs.

  The server device 4 constitutes the core of the system of this embodiment, and a WEB server (not shown) in the server device 4 is necessary for the input device 3 in response to access from each input device 3. It has a function to provide data. That is, each input device 3 can download necessary information such as a question format from a WEB server and upload information through client software having a standard browser function.

  FIG. 3 shows a monitor screen displayed on the display means 34 after the input device 3 is started. The user of the input device 3 inputs request information indicating a request for the temperature of the current space A. This is a screen for selecting and inputting a request for temperature such as “I want you to raise the temperature” and “I want you to lower the temperature”, and pointing the check fields C1 and C2 corresponding to the corresponding request with a mouse etc. By checking using the device and clicking the transmission button B1, the request information of a specific user at that time is uploaded to the server device 4 together with the identification information of the user. The screen for inputting the request information can be displayed on the input device 3 at an arbitrary timing not only when the input device 3 is started but also by a user operation or an instruction from the server device 4. .

  The request information acquisition means 41 of the server device 4 uses the browser software installed in each input device 3 used by the user, and the request information transmitted to the server device 4 side together with the identification information and the air conditioning number. The request information is collected and stored in the request temporary storage means 42 in association with the identification information and the air conditioning number.

  In response to the request information collected from the input device 3 in this way, the control plan planning unit 44 of the server device 4 stores the request information stored in the request temporary storage unit 42 and the database 43. And calculate the ratio (request ratio) to the total number of users of the two conflicting demand information such as "I want you to raise the temperature" and "I want you to lower the temperature". The target temperature To is determined in light of the determination criterion rule, and the history of the target temperature To is stored in the control history storage unit 45. The total number of users is determined by the number of activated input devices 3 and the number of users in the space A counted by an entrance / exit management device (not shown).

  Specifically, the control plan creation means 44 performs processing according to the flowchart of FIG. First, when the request information acquisition unit 41 collects the request information together with the identification information from each input device 3 (step S1), it collates with the information in the request temporary storage unit 42 (step S2). When the request information is stored in the request temporary storage unit 42 in association with the identification information, the request information acquisition unit 41 acquires the request information to which the same identification information as the already stored identification information is added. The request information already stored in association with this identification information is erased, and the newly acquired request information is stored in association with this identification information. That is, a control effective data extraction process in which the latest request information is associated with each piece of identification information is performed (step S3). The request temporary storage means 42 is composed of a high-speed storage device such as a cache memory in the CPU.

  Next, the control plan drafting means 44 calculates a request rate from the valid data of the request information, and performs a process based on the agreement formation logic based on the request rate (step S4). The consensus building logic performed by the control planning means 44 will be described based on the flowchart of FIG. First, it is assumed that the request information of the users H1 to H3 is “I want you to raise the temperature”, whereas the request information of the user H4 is “I want you to lower the temperature”. The request rate calculated by the control planning means 44 in step S21 of the flowchart is 3/4 of the request rate of “I want to raise the temperature” and 1/4 of the request rate of “I want you to lower the temperature”. The target temperature To is determined by the logic based on the request rate and the criterion area shown in FIG. In other words, the region that meets the conditions is determined in step S22, and the above calculated request rate is plotted on the criterion of FIG. 5B. If the plotted position is in the range of □, the current target temperature To In the case of ▽, the temperature that is lower than the current target temperature To by a predetermined value (for example, Δt = 0.5 ° C.) is set as a new target temperature To. (Set temperature) A temperature that is a predetermined value (for example, Δt = 0.5 ° C.) higher than To is set as a new target temperature To (steps S23 to S25). The target temperature To is determined by this plot (step S26).

  Thus, the new target temperature To (target temperature To = target temperature To ± Δt) is obtained from FIG. 5B (step S5), and the target temperature To is determined (step S6).

  Then, the request temporary storage means 42 deletes the request information that has been stored for a predetermined time and the identification information associated therewith (step S7). Therefore, there is no identification information or request information that is user information remaining in the temporary request storage means 42, and even if the information enters the server device 4 via the communication network NT from the outside, such information will be stored after a predetermined time. Since it has been deleted, information cannot be misused.

  Thereafter, the information of the determined target temperature To is transmitted to the air conditioning control device 2, and a process of setting a new target temperature To in the air conditioning control device 2 is performed (step S8). The above operation is repeated until the operation is stopped. The air conditioning control device 2 includes a room temperature sensor 2a that measures the temperature in the space A, and the air conditioning equipment device 1 is adjusted so that the temperature measurement data measured by the room temperature sensor 2a matches the determined target temperature To. Control.

  As described above, since the user can be identified without registering a large number of pieces of identification information in the server device 4, it is not an excessive specification, but a personal authentication method for registering a large number of pieces of identification information in the server device 4. In comparison, the registration cost of identification information can be suppressed.

  Next, feedback processing for confirming whether or not the request input by the user has been adopted by the server device 4 and the air conditioning control according to the request has been performed will be described. First, in FIG. 4, after setting a new target temperature To in the air conditioning control device 2 in step S8, this target temperature To is sequentially stored in the control history storage means 45 together with the set date and time, and the control history of the target temperature To is the control history. It is stored in the storage means 45.

  The input device 3 includes request history storage means 33 that stores a history of input request information such as cookies, and transmits a feedback request to the server device 4 as shown in the flowchart of FIG. 4 (step S11). ), Identification information, air conditioning number and latest request information history are transmitted along with the feedback request.

  In the server device 4 that has received the feedback request to which the identification information, the air conditioning number, and the latest request information history are added (step S12), the feedback information generation unit 46 receives the latest request information history and the control history storage unit 45. The control history (control history of the area corresponding to the sent air conditioning number) is compared, the date and time of the request information and the request content (“I want you to raise the temperature” or “I want you to lower the temperature”), From the date and time of determination of the target temperature To and the comparison result with the direction of change (ascending direction or descending direction), it is determined whether or not the air conditioning control according to the request has been performed, and feedback information (information content) of the determination result is generated (Step S13), based on the identification information, the feedback information is returned to the input device 3 that is the source of the feedback request (step S13). Flop S14).

  For example, as shown in FIG. 6, the user H1 transmits request information “I want to raise the temperature” from the input device 3 at 16:00, and the target temperature To rises by 1.0 ° C. at 16:20. Suppose that Thereafter, when the user H1 transmits a feedback request from the input device 3 at 17:30, the feedback information generating means 46 of the server device 4 obtains the request “I want to raise the temperature” obtained at 16:00, It is determined that the target temperature To has been increased at 16:20, and feedback information including image data “the temperature has increased as requested by you” is generated and transmitted. Upon receiving the feedback information, the input device 3 displays the image data on the display means 34 and notifies the user of the determination result.

  In this feedback process, the identification information and the request information history transmitted from the input device 3 to the server device 4 are deleted from the server 4 when the server device 4 returns the feedback information.

  In the feedback processing, when only the air conditioning number is added to the feedback request without using the identification information, the server device 4 generates feedback information of the area corresponding to the air conditioning number, and the input device 3 is the server device. 4 may be accessed to browse this feedback information.
