  The presence / absence determining unit 20 determines the presence / absence of the person based on the power consumption based on the current sensor 7 of each power monitoring unit 4 and the illuminance data obtained by the illuminance sensor 8 obtained from the synchronized block chain. For example, when the power consumption obtained by the current sensor 7 of the power monitoring unit 4 to which the TV is connected is a predetermined value or more and the illuminance data of the illuminance sensor 8 of the power monitoring unit 4 is a predetermined value or more, It is determined that there is a person in the room where the power monitoring unit 4 exists.

  The smart key processing unit 26 has a function of sending a command to lock the smart key system at the entrance of the building 1 when the presence / absence determination unit 20 determines that a person is present. Thus, even when the entrance lock is forgotten when returning home, the entrance lock is automatically performed, which is advantageous in terms of security.

  The lightning surge protection unit 27 should block the power supply path to the electrical device 3 in order to protect the electrical device 3 from the lightning surge based on the detection data of the lightning sensor 19 of each power monitoring unit 4.

The certain number of times includes one time.

  This block data includes the acquisition date and time and identification information of the power monitoring unit 4 to which the distributed database 28 belongs. Further, each piece of data constituting the block data (power consumption or detection data for each sensor) includes type information indicating a data type such as power consumption or illuminance data. The block data is broadcast to the other power monitoring unit 4 via the communication unit 30.

  Further, similar block data received from the other power monitoring unit 4 via the communication unit 30 is additionally written into the distributed database 28 (at the end of the block chain). As a result, a block chain composed of a large number of block data is formed in synchronization in the distributed database 28 of each power monitoring unit 4.

  The processing unit 5 of each power monitoring unit 4 is activated by power feeding from the power supply port 2 when the power monitoring unit 4 is connected to the power supply port 2. In response to this, the block chain forming unit 29 of the processing unit 5 forms a block chain network with the processing unit 5 of the other power monitoring unit 4 that is already connected to the other power supply port 2, and blocks It becomes a chain node. That is, from this time, in the distributed database 28 of the power monitoring unit 4, the block chain is the same as that of the processing unit 5 of the other power monitoring unit 4 (synchronized). Will be shared.

  FIG. 4 is a block diagram illustrating a configuration of the control unit 10. As shown in the figure, the control unit 10 has two CPUs (central processing units), that is, a CPU 31 and a CPU 32. Detection data of the current sensor 7 is input to the CPU 31 via an ADC (analog / digital converter) 33. The CPU 31 obtains the current supplied to the electrical device 3 by analyzing the value of the current flowing through the secondary coil of the current sensor 7 and the induced voltage based on this detection data according to an appropriate program.

  The CPU 32 receives data detected by the illuminance sensor 8 and the temperature / humidity sensor 9, current values obtained by the CPU 31, and the like. The CPU 32 monitors power consumption (Kw), power consumption (Kw / h), and the like in the electric device 3 based on the current value according to an appropriate program.

  For example, the CPU 32 can communicate with the CPU 32 of another power monitoring unit 4 via the communication module 34 compliant with IEEE 802.15.4. That is, the communication module 34 constitutes the communication unit 30 of the processing unit 5.

  Further, the command transmission unit 14 in FIG. 2 and the like can be connected to the CPU 32 via the expansion port 35. That is, the expansion port 35 constitutes the additional function connection unit 15 in FIG.

  Further, the CPU 32 is connected to a relay 36 constituting the power cut-off unit 13 in FIG. The processing unit 5 of FIG. 3 is configured by causing the CPU 32 to run a program including an OS suitable for configuring the block chain described above.

  FIG. 5 is a flowchart showing a part of processing in the processing unit 5 of the power monitoring unit 4 connected to the power supply port 2 in the building 1. This process is repeatedly performed at regular short time intervals.

  This processing is performed by the processing unit 5 of any one power monitoring unit 4 connected to the power supply port 2, and as a result, information that needs to be notified to the processing unit 5 of the other power monitoring unit 4 is generated. May notify the processing unit 5 of the other power monitoring unit 4 via the communication unit 30.

  In this case, the power monitoring unit 4 that performs the processing of FIG. 5 can make a determination based on the order of connection to the power supply port 2 or can determine the power monitoring unit 4 based on a user instruction. For example, the power monitoring unit 4 connected to one of the power supply ports 2 may be determined first.

  Further, the processing of FIG. 5 may be performed by the processing units 5 of two or more power monitoring units 4 connected to the power supply port 2. In this case, since the block chain in the distributed database 28 of the processing unit 5 of each power monitoring unit 4 is synchronized as described above, each power monitoring unit 4 is based on the block chain of its own distributed database 28. Similar processing results can be obtained even when the processing of FIG. 5 is performed at the same time.

  When the processing of FIG. 5 is started, the processing unit 5 first causes the presence / absence determination unit 20 to obtain detection data of the current sensor 7, the illuminance sensor 8, and the temperature / humidity sensor 9 in each power monitoring unit 4 from the block chain of the distributed database 28. Based on this, presence / absence determination processing for determining whether there is a person in the building 1 is performed (step S1). The detection data acquired from the block chain is the latest one or has occurred within a certain past time from the processing point. The same applies to the following processing.

  In this determination, for example, if the current value indicated by the detection data of the current sensor 7 is equal to or greater than a predetermined value and the illuminance indicated by the detection data of the illuminance sensor 8 is equal to or greater than a predetermined value, it is determined that there is a human. In addition, the accuracy of determination can be improved in consideration of the temperature and humidity indicated by the detection data of the temperature / humidity sensor 9. For example, if the temperature is within a predetermined range, there is a high probability that a person exists.

  Next, it is determined whether or not monitoring of a human such as a child or an elderly person is necessary, that is, whether or not the user is instructed to perform such monitoring (step S2). If it is determined that monitoring is not necessary, the process proceeds to step S6. If it is determined that monitoring is necessary, it is determined whether or not it is determined that a person is present in the building 1 by the presence / absence determination process in step S1 (step S3).

  When it is determined in step S3 that a human is present in the building 1, the human monitoring unit 22 detects the current position sensor 16 connected to the additional function connecting unit 15 of each power monitoring unit 4 from the block chain. Based on the data, a predetermined output relating to the current position of the person is performed (step S4), and the process proceeds to step S6.

  The predetermined output corresponds to, for example, displaying a mark indicating the position of the person on the floor plan of the building. Such a display may be transmitted to a mobile device registered in advance.

  If it is determined in step S3 that no human is present in the building 1, there is a possibility that the person to be monitored has gone out of the building 1, so a predetermined warning indicating that fact is output (step S5). ), And proceeds to step S6. This output can be performed, for example, by outputting sound, an image, or the like. Such a warning may be transmitted to a mobile device registered in advance.

  In step S6, it is determined whether or not it is determined that the person exists in the building 1 by the presence determination process in step S1. If it is determined that no human is present in the building 1, the process proceeds to step S12.

  On the other hand, if it is determined in step S6 that a human is present, the process proceeds to step S12 after performing the processes in steps S7 to S11.

  That is, in the command instruction process in step S7, the command instruction unit 21 uses the detection data obtained from the block chain for the illuminance sensor 8 or the temperature / humidity sensor 9 of each power monitoring unit 4 as the lighting device or the air conditioner. A command to be transmitted to the lighting apparatus or the air conditioner is instructed to the power monitoring unit 4 to which the conditioner is connected. The command instruction may be broadcast. When the lighting apparatus or the air conditioner is connected to the power monitoring unit 4, the command to be transmitted to the lighting apparatus or the air conditioner by the command instruction unit 21 to the command transmitting unit 14. Instruct.

  For example, the detection data of the illuminance sensor 8 or the temperature / humidity sensor 9 is compared with a reference value. If the illuminance value or temperature / humidity indicated by the detection data is smaller than the reference value, the illuminance sensor 8 or the temperature / humidity sensor 9 is provided. The power monitoring unit 4 is instructed with a command for increasing the output of a lighting fixture or an air conditioner connected thereto.

  When the power monitoring unit 4 receives the command instruction, the command monitoring unit 4 transmits the command to the lighting apparatus by the command transmission unit 14 connected to the additional function connection unit 15. Thereby, for example, the illuminance due to the illumination of the luminaire can be matched with the reference value.

  In the fire notification process in step S8, the fire notification unit 23 detects from the block chain the fire sensor 17 connected to the temperature / humidity sensor 9 of each power monitoring unit 4 or the additional function connection unit 15 of each power monitoring unit 4. When it is determined that a fire has occurred based on the data, the fact is notified.

  In addition, notification that a fire has occurred can be performed by outputting sound, an image, or the like, or sending a mail indicating that a fire has occurred to a mobile device registered in advance.

  In the security process of step S9, the safety process unit 24 exists in the building 1 based on the detection data obtained from the block chain for the current position sensor 16 connected to the additional function connection unit 15 of each power monitoring unit 4. Then, a process related to the determined human current position is performed.

  The process related to the current position of the person corresponds to, for example, a process of displaying a sketch of the building 1 on the current position of the person and displaying a mark indicating the current position thereon. The current position may be output by voice or the like. Further, such display and output information may be transmitted to a mobile device registered in advance. Such security processing is performed when instructed by the user in advance.

  In the water leakage notification process of step S10, the water leakage notification unit 25 indicates that there has been water leakage based on the detection data obtained from the block chain for the water leakage sensor 18 connected to the additional function connection unit 15 of each power monitoring unit 4. When it is detected, an output for notifying that effect is performed.

  In this case, for example, the notification to be output is performed by transmitting and displaying the fact that water leakage has occurred in a mobile device registered in advance, or by outputting it by voice or an image. Thereby, the user can immediately know that water leakage has occurred in the washing machine or bathroom.

  In the smart key process of step S11, a command to lock the smart key system at the entrance of the building 1 is sent. In response, the smart key system locks the entrance. As a result, even if you forget to lock the entrance and enter the building 1, it is detected that the entrance has been entered (step S6), and the entrance is automatically locked. it can.

  In step S12, in order to protect the electrical equipment 3 from lightning surge, it is determined whether or not the power supply path to the electrical equipment 3 in each power monitoring unit 4 should be interrupted. In S <b> 13, a shut-off command to the effect that the power supply path should be shut off is transmitted to each power monitoring unit 4, and the processing in FIG. 4 ends. If it is not determined that it should be blocked, the processing in FIG.

  The determination as to whether or not to interrupt the power supply path is made, for example, based on whether the distance to the thundercloud indicated by the latest detection data of the lightning sensor 19 obtained from the block chain or whether the lightning energy exceeds a predetermined value. Alternatively, based on weather information obtained via a network such as the Internet, the determination may be made based on, for example, whether a lightning strike has occurred in a predetermined vicinity.

  When the cutoff command is transmitted, the power supply path to the electrical equipment 3 connected to each power monitoring unit 4 that has received this command is shut off by the power cutoff unit 13 of the power monitoring unit 4. Thereby, damage of the electric equipment 3 by a lightning surge, etc. are prevented.

  As described above, according to the present embodiment, the presence / absence determination unit 20 determines whether there is a person in the building 1 based on the detection data of the current sensor 7 and the illuminance sensor 8. This determination can be made without using it. Moreover, when it cannot be determined by the human sensor, for example, even when a human is away from the sensing range of the human sensor, it can be determined that a human is present in the building 1.

  Further, in addition to the current sensor 7 and the illuminance sensor 8, it is determined whether or not a person is present in the building 1 in consideration of the detection data of the temperature / humidity sensor 9. Therefore, the presence / absence of a person is determined with higher accuracy. be able to.

  In addition, when the presence / absence determination unit 20 determines that there is a person, the above-described command instruction process (step S7) is performed, so that the lighting apparatus and the air conditioner can be appropriately output for the person. Can be controlled. Alternatively, the presence or absence of a person may be determined for each room in the building 1, and the electrical device may be controlled for each room where a person is present according to the result. In this case, it is possible to set in advance in the processing unit 5 of each power monitoring unit 4 which room each power monitoring unit 4 is required in and in which room the electrical equipment 3 is connected.

  In addition, since the above-described human monitoring unit 22 performs a warning that there is no person to be monitored according to the determination result of the presence / absence determination unit 20, and an output related to the current position of the human determined to be present. The person to be monitored can be monitored by appropriately using the determination result of the existence determination unit 20.

  In addition, when the presence / absence determination unit 20 determines that there is a person, the processing unit 5 performs the fire notification process, the security process, the water leakage notification process, and the smart key process in steps S8 to S11. These processes can be performed while appropriately using the determination result by the presence / absence determination unit 20.

  Further, since the processing unit 5 transmits the interruption command by the lightning surge protection unit 27 based on the detection data of the lightning sensor 19, it is possible to effectively protect the electrical equipment 3 from the lightning surge. .

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this. For example, as the electrical equipment 3, in addition to the above-described lighting fixtures and air conditioners, other home appliances such as a fan, a heating appliance, a television, a refrigerator, and the like may be included.

  In addition to the current sensor 7, the illuminance sensor 8, and the temperature / humidity sensor 9, the presence / absence determination unit 20 may determine presence / absence of a human in consideration of detection data from a human sensor. Further, the presence / absence of a person may be determined based on the detection data of the current sensor 7 and the temperature / humidity sensor 9 without considering the illuminance data of the illuminance sensor 8.

  That is, the presence / absence determination unit 20 includes an illuminance sensor 8 that detects an amount of power consumed by each power monitoring unit 4 of the block chain, and an illuminance, temperature, and humidity around each power monitoring unit 4. It may be determined whether or not there is a person in the building 1 based on the detection data of one or more sensors selected from the above.

  Further, the range of the block chain network sharing the block chain, that is, the range of the power monitoring unit 4 to be processed in FIG. 5 is not limited to the building 1, but the power monitoring existing in a plurality of buildings 1 or a certain area. The range of part 4 may be sufficient.

  Further, instead of the CPUs 31 and 32, the first to third CPUs are adopted, the first CPU and the second CPU analyze the signal from the current sensor 7 and obtain the current, and the process according to the flowchart of FIG. The block chain forming unit 29 in FIG. 3 may be processed by the third CPU.
