The present invention relates to a parasitic control method and apparatus for HEMS that can be controlled in cooperation with lighting, and an energy-saving air-conditioning control method and apparatus using the same.

  HEMS for examining the usage amount of electricity, gas, etc. on a monitor screen or the like in connection with home appliances or electrical equipment or optimally controlling home appliances has been studied (see Patent Documents 1 to 5).

  In the conventional system, as illustrated in FIG. 1, a router 14 is connected to an existing HEMS 10 via a gateway 12, and an air conditioner 22, a lighting device 24, and a HEMS controller 26 are connected by, for example, a wired home network 20. Each connected device is capable of mutual data communication by a common communication standard called ECHONET Lite and is also called an EL device.

JP 2011-142753 A JP, 2014-124067, A JP 2014-222396 A Japanese Patent Laying-Open No. 2015-224854 Japanese Unexamined Patent Publication No. 2016-23819 JP 2011-220608 A (Claims 11 and 12, paragraphs 0121 to 0122) JP 2014-129936 A

  Conventionally, for energy-saving control, it is necessary to use a plurality of infrared (IR) remote controllers for each EL device or to control by the user using the HEMS controller 26, and the device cooperation desired by the user is created by himself. In addition to being difficult, control performed by the user for energy saving measures may harm the comfort of the indoor environment, but it must be controlled by interrupting the outside or enhancing the energy saving effect without the user's knowledge. I couldn't.

  The present invention has been made to solve the above-mentioned conventional problems, and a first object is to enable interruption to an existing HEMS from the outside.

  The second object of the present invention is to enhance the energy saving effect without the user's knowledge.

  In the present invention, a wireless LAN can be connected to an existing HEMS home network, a wireless terminal is connected using the wireless LAN, and the existing HEMS is interrupted using the parasitic control software installed in the wireless terminal. The first problem is solved by a parasitic control method for HEMS that controls home appliances connected to a home network.

  Here, the wireless terminal can download the required service from an external server.

  The present invention also includes a wireless LAN connection means for enabling connection of a wireless LAN to an existing HEMS home network, a wireless terminal connected using the wireless LAN connection means, and the wireless terminal installed in the wireless terminal Parasitic control software, and using the parasitic control software, the HEMS parasitic control device is characterized in that it can control an electric home appliance connected to a home network by interrupting an existing HEMS, Similarly, the first problem is solved.

  The present invention is also an energy-saving air-conditioning control method using the parasitic control method for HEMS, wherein the air-conditioner connected to the home network is operated until the initial set temperature is reached, and the predetermined time is reached after the initial set temperature is reached. When the time has elapsed, the set temperature is changed by a predetermined temperature in the energy saving direction, and even if the user instructs to change the set temperature, the first time is ignored, thereby solving the second problem. It is a thing.

  Here, when the user gives an instruction for changing the set temperature for the first time, the color of illumination can be changed to change the sensible temperature.

  Further, when the user gives an instruction for changing the set temperature for the second time or later, the set temperature can be changed.

  Further, the actual set temperature can be displayed on the wireless terminal.

  The present invention is also an energy-saving air-conditioning control device using the HEMS parasitic control device described above, wherein an air-conditioner connected to a home network is operated until reaching an initial set temperature, and a predetermined time has elapsed since the initial set temperature was reached. The energy-saving air-conditioning control device is equipped with software that controls the set temperature to change in the energy-saving direction by a predetermined temperature when it has passed, and ignores the initial setting even if the user instructs to change the set temperature. Similarly, the second problem is solved.

  According to the present invention, since it is possible to interrupt an existing HEMS from the outside, the user simply performs a conventional operation using, for example, an IR remote controller, and the actual control is not performed by the system connected to the outside. Therefore, the user does not need to think about it, and the energy saving effect can be enhanced where the user does not know.

  Particularly, when the required service can be downloaded from the server, the linkage control is easy.

  In the air conditioning control, the first set temperature change instruction is ignored, and the lighting is changed to warm color (during heating) or cold color (during cooling) as necessary. A comfortable indoor temperature environment can be maintained while planning.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited by the content described in the following embodiment and an Example. In addition, the constituent elements in the embodiments and examples described below include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those in the so-called equivalent range. Furthermore, the constituent elements disclosed in the embodiments and examples described below may be appropriately combined or may be appropriately selected and used.

  FIG. 2 shows an overall configuration of an embodiment of a HEMS system improved to carry out the present invention. This system makes it possible to connect a wireless LAN (in this case, WiFi) to an existing HEMS in a HEMS system having an existing HEMS 10, a gateway 12, a router 14, a home network 20, an air conditioner 22, and a lighting device 24 similar to FIG. Wireless router 30 for wireless communication, a wireless terminal 32 that is WiFi-connected using the wireless router 30 (here, an iOS device, for example, iPhone), and parasitic control software (here, “mistletoe”) installed in the wireless terminal 32 36), a device list creation algorithm 38 that operates in conjunction with the parasitic control software 36, a user setting algorithm 40, a temperature setting algorithm 42, an energy saving control algorithm 44, and an illumination color determination algorithm 46. It is. In the figure, 23 is an infrared (IR) remote controller for controlling the air conditioner 22, and 50 is a Web server (service server) capable of communicating with the wireless terminal 32.

  The air conditioner 22 and the lighting device 24 are commercially available EL devices compatible with ECHONET light, and can be operated by the IR remote controller 23.

  The system operates when a wireless terminal (for example, another iPhone, iPad, iMac) having the same OS (here, iOS) as the wireless terminal 32 is in the same WiFi environment.

  The home network 20 links an air conditioner 22 and a lighting device 24.

  By changing the router 14 to a wireless router, the separate wireless router 30 can be omitted.

  This system does not have the HEMS controller 26 shown in FIG. 1, and is automatically controlled by a method described in detail below.

  The wireless terminal 32 is composed of, for example, an iOS device. As shown in detail in FIG. 3, the GCD (Grand Central Dispatch) asynchronous UDP, which is a library obtained from the iOS 32A and the SSNG (Super Speed Speed Node Gerrerator) for Echonet Lite. (User Data Protocol) socket (GCD Async UDP Socket) 32B, output socket (Out Socket) 32C, EL transmission (Send EL) 32D, input socket (In Socket) 32E and EL reception (Receive EL) 32F, view controller ( (View Controller) 32G, and a user interface (UI) 32H configured with a touch panel, for example, for input and output. Since this iOS device uses a plurality of libraries, the library is managed using Cocoa Pods, which is a library management tool of iOS.

  The Receive EL 32F incorporates a program that sets tid to a value that is not normally used and performs filtering so as not to accept an unrelated EL command. That is, in the general process, as shown in FIG. 4A, in the case of SET, tid is sequentially incremented by 1 from 0000 to FFFF until the system is stopped (the first SET is 0001, the second SET is 0002). Accordingly, the GET tid is not changed because it is sent using the SET tid as it is.

  On the other hand, in this embodiment, as illustrated in FIG. 4B, by setting the tid at the time of SET to a value (eg, 1234) that is not normally used, only GETs from devices to be controlled are obtained. To receive.

  FIG. 5 shows the processing procedure of the EL command in the embodiment.

  First, in step 101, it is determined whether it is transmission or reception. If it is determined in step 101 that the transmission is performed, the process proceeds to step 102, and control is determined by the view controller 32G. Next, the process proceeds to step 103, and an EL command is created by EL transmission (Send EL) 32D. Next, the process proceeds to step 104, and an EL command is transmitted by the output socket (Out Socket) 32C. As a result, the EL device ((air conditioner 22 or lighting device 24) operates in step 105 and the process returns to step 101.

  On the other hand, when it is determined in step 101 that the signal is received, the process proceeds to step 112, and the EL command is received by the input socket (In Socket) 32E. Next, the process proceeds to step 113 where an EL command is created by EL reception (Receive EL) 32F. Next, the process proceeds to step 114 and is used for control by the view controller 32G. Next, the process proceeds to step 115, where the reception result (for example, the air conditioner temperature) is displayed on the user interface (UI) 32H, and the process returns to step 101.

  In the user setting algorithm 40, the illumination illuminance is set to a brightness suitable for the user, a security code is set, the age and gender of the person using the room to be used is set, the family Set presence / absence, set life patterns (profession, students, etc., control according to time (support darkness at bedtime, dazzle when waking up), etc.), favorite TV program (variety, animation, favorite Entertainers, etc.).

  The entire system operates according to a procedure as shown in FIG.

  That is, in step 201, multicasting is performed for EL devices in the same WiFi environment, and in step 202, a device list as illustrated in FIG. 7A is created. Next, in step 203, the service communicates with the Web server (service server) 50, searches for services that can be linked, and displays them on the wireless terminal 32 as illustrated in FIG. 7B. Next, in Step 204, a service (here, air conditioner energy saving control) that is desired to be used is selected. Next, the process proceeds to step 205, and it is determined how many times the access is made. When it is determined that it is the first time (n = 1), the process proceeds to step 206, a password for ensuring security is input, the service to be used is downloaded from the web server 50 in step 207, and the service is started in step 208 To do. After the service ends, the service is stopped at step 209 and the process returns to step 204.

  On the other hand, if it is determined in step 205 that the access is the second or later (n ≧ 2), the process proceeds to step 217 without inputting the personal identification number, is downloaded from the Web server 50, and the service is started in step 218. After the service ends, the service is stopped at step 219 and the process returns to step 204.

  An example of the selected service is shown in FIG. Here, the air conditioner energy saving control is selected.

  FIG. 8 shows a specific control procedure when air-conditioner energy saving control during heating is selected.

  First, a device list creation algorithm 38 including a multicast step 201 and a device list creation step 202 similar to those shown in FIG. 6 is executed, and download steps 207 and 217 and service start steps 208 and 218 similar to those shown in FIG. Run the service update algorithm that contains it.

  Next, the process proceeds to step 301 of the temperature setting algorithm 42 for determining the temperature limit at which the user does not feel uncomfortable, and waits for the room temperature to become the initial set value by controlling the air conditioner 22. Next, the routine proceeds to step 302 where the initial set value is memorized. Next, the process proceeds to step 303 to determine whether or not the temperature is the lowest.

  If the determination result in step 303 is negative, the process proceeds to step 401 of the energy saving control algorithm 44, the set value is lowered by a predetermined temperature, for example, 1 ° C., the process proceeds to step 402, and the timer is reset. Next, the process proceeds to step 403, where it is determined whether or not the user has instructed the temperature change by the IR remote controller 23, for example. If the determination result is NO, the process proceeds to step 404 to determine whether or not a predetermined time, for example, 20 minutes, at which the room temperature is considered to have settled has been waited. If the determination result is NO and it is determined that 20 minutes have not elapsed, the process returns to step 403.

  On the other hand, when it is determined that the determination result in step 404 is positive and 20 minutes have been waited, the process returns to step 303 to determine whether or not the temperature is the lowest.

  On the other hand, when it is determined that the determination result in step 403 is positive and there is an instruction to change the temperature, the process proceeds to step 405 to determine how many times the instruction is made. When it is determined that the instruction is the first time (n = 1), the process proceeds to step 501 of the illumination color determination algorithm 46, the temperature change instruction is canceled, the process proceeds to step 502, the illumination color is changed to a warm color, and the energy saving control algorithm Returning to step 402 of 44.

  On the other hand, if it is determined in step 405 that the instruction is for the second time or later (n ≧ 2), the process proceeds to step 406, where the initial set value is increased by a predetermined value, for example, 1 ° C., and the process returns to step 402.

  An example of temperature setting in the temperature setting algorithm 42 is shown in FIG.

  In this embodiment, the temperature at which the air conditioner was stopped last time is stored and used. That is, the temperature when the air conditioner is stopped at P1 on the previous day is stored as the minimum value Tmin. The next day, the temperature is lowered to the minimum value Tmin at P2. The next day, when the set value is further lowered by the user by the IR remote controller 23, the minimum temperature is updated from Tmin to Tmin '(lowered) as in P3.

  Note that the initial set temperature can be reflected by grasping the state of a person using a human state sensor such as a body temperature, a skin surface temperature, a sweating amount, and a heart rate. Moreover, control according to room temperature and humidity can also be performed.

  In the energy saving control algorithm 44, an example of a temperature change and a lighting color change when heating is used is shown in FIG.

  The initial set temperature is Ts. In Q1, since there is no operation instruction from the IR remote controller 23, the set temperature is lowered by 1 ° C.

  Even if there is a temperature change instruction from the IR remote controller 23 at Q2, since it is the first time, the instruction is canceled, while a temperature change is detected at Qc1, and the illumination color is changed to a warm color at Qc2.

  When the temperature change instruction is received again from the IR remote controller 23 in Q3, the temperature is raised by 1 ° C. from Ts in Q4 because the second instruction is received.

  In Q5 to Q8, since there is no operation instruction from the IR remote controller 23, the set temperature is decreased by 1 ° C. every predetermined time (here, 20 minutes).

  In Q9, the minimum value (recommended temperature) is maintained.

  Here, the hatched area between the solid line (the set temperature of the air conditioner by the system) and the alternate long and short dash line (the display temperature of the IR remote controller) saves energy compared to the conventional case.

  As described above, since the actual set temperature is different from the display temperature of the IR remote controller 23, the actual set temperature can be displayed on the UI 32H of the wireless terminal 32 to notify the user as shown in FIG.

  An example of setting the illumination color by the illumination color determination algorithm 46 is shown in FIG.

  An illumination color can be selected according to a living scene (for example, a study room, a work room, a bedroom, etc.), and the illumination color can be changed according to a person's condition. For example, as shown in FIG. 11A, cold light such as blue light is used during study or work. Also, when it feels hot, it is assumed that the light is cold-colored, for example, blue light, as shown in FIG. On the other hand, for those who feel cold, warm color light, for example, red light, is selected as shown in FIG.

  The above embodiment is an example of heating, but at the time of cooling, it is determined at step 303 in FIG. 8 whether or not the maximum temperature is reached. In steps 401 and 406, the set value is increased by, for example, 1 ° C. Change it.

  In the embodiment, a device having an iOS, such as iPhone, is selected as the wireless terminal 32. However, the type of the wireless terminal is not limited to this, and an ipad, iMac, and Android OS having the same iOS are used. It may be a personal computer that has a smartphone, a tablet, or a Windows (registered trademark) OS, and is capable of wireless communication.

  Moreover, in the said embodiment, although this invention was applied to the cooperation control of an air-conditioner and illumination, the application object of this invention is not limited to this.
