[0002]
[Prior art]
In order to realize energy saving, while developing the power saving inside the equipment, it is also necessary to ask the user side for caution and cooperation regarding how to use the equipment. As a method for encouraging users to save energy, conventionally, an advertisement is presented from the government or a power company, and the manufacturer describes the power consumption in the device specification.
[0003]
[Problems to be solved by the invention]
However, in daily life, it is considered that there is little if the user is clearly aware of the amount of power consumption when using the device. Even if the amount of power used as one household total is known, it is not possible to grasp how much power each device actually consumes.
[0004]
Possible causes of increased power consumption include failure, component wear, or equipment malfunction due to electrical leakage. It is necessary to prevent the inside of the device from being heated while the user is not aware of the abnormality of the device, causing the user to be burned or causing a fire. In addition, the wear of consumable parts may not be noticed, and a load higher than normal may be applied when the device is in operation.
[0005]

Once the breaker is shut off, in many cases the power supply panel installed at a high place is operated to perform restoration work, but it is considered that the work at a high place involves danger.
[0006]
In the recent super-aged society in Japan, the number of patients with dementia is expected to increase in the near future, and it will be necessary to consider the possibility that devices operated by patients will be left as they are. For example, when a patient operates and leaves a device intended for heating in a time zone that is unreachable by the family living together, it is necessary to prevent a fire from occurring.
[0007]
  In view of the above-described conventional problems, the present invention detects an amount of current used by a device.TheApplied to detect abnormalities of equipment and predict the life of the equipment to contribute to the normal use of equipment, system to prevent breaker blockage due to exceeding the power supply allowance when using multiple equipment, and abnormal use status of equipment The purpose is to provide a system to deal with.

The power obtained by connecting the outlet unit 101a to the power source is supplied to the device 302 from the outlet unit 101b via the current flow rate detection circuit unit 102 and the current cutoff circuit unit 103, while being charged to the battery unit 107, When the power supply from the unit 101a is stopped, the necessary power is supplied to the control processing unit 104.
[0024]
The current flow rate detection circuit unit 102 detects the current flow rate flowing into the device 302 connected to the outlet unit 101b. The current interruption circuit unit 103 interrupts current inflow to the outlet unit 101b in accordance with an instruction from the control processing unit 104 described later. The control processing unit 104 receives the current flow rate data detected by the current flow rate detection circuit unit 102 and sends data to a communication processing unit 105 described later or issues a current cutoff instruction to the current cutoff circuit unit 103. The communication processing unit 105 transmits the current flow rate data received from the control processing unit 104 on the bus 108, or receives and decodes an instruction from a controller connected via the bus 108. The electronic culture is assumed to be compliant with the HBS standard (ET-2101), for example. The RS-232c or IRda circuit unit 106 exchanges data with the display or input device connected via the RS-232c or IRda, such as the current flow data held by the control processing unit 104 and the presence / absence of a current interruption instruction. I do.
[0025]
FIG. 2 is a detailed configuration diagram of the control processing unit 104. As shown in FIG. 2, the control processing unit 104 includes a change detection unit 201, a data storage unit 202, a control unit 203, and a measurement interval setting timer unit 204.
[0026]
The change detection unit 201 receives current flow rate data detected by the current flow rate detection circuit unit 102 for each timing signal from a measurement interval setting timer unit 204 described later. The data accumulation unit 202 accumulates output data from the change detection unit 201. The control unit 203 compares the detection result of the change detection unit 201 with the information of the data storage unit 202 sampled last time, and outputs the latest data to the communication processing unit 105 when there is a change. If the change data is a value that requires immediate current interruption, the current interruption circuit unit 103 is instructed to interrupt current. In addition, when a current cut command is received from the communication processing unit 105, the current cut circuit unit 103 is similarly instructed to cut off the current. Further, when there is a request for confirmation of the presence / absence of current flow data or current interruption instruction from the IRda circuit unit 106, the information is output to the IRda circuit unit 106. In addition, the timer of the measurement interval setting timer unit 204 is activated.

And a bus 108. Information on the device 302 obtained by the current usage detection adapter 301 is passed to the controller 303 via the bus 108.
[0028]
The current usage detection adapter 301 is connected to a power source, and the device 302 receives power from the current usage detection adapter 102. When the device 302 is used, a current flows from the current usage amount detection adapter 301 to the device 302, and the current usage amount detection adapter 301 creates a message from the current flow rate information and transmits it to the controller 303 via the bus 108. . The controller 303 detects the amount of current used by the device 302 from the received information and determines whether an abnormality has occurred in the device 302. As a result of the determination, if it is determined that there is an abnormality, the abnormality occurrence information is transmitted to the status display device 304. The status display device 304 is a display device such as a CRT, for example. The status display device 304 receives abnormality occurrence information and displays a screen that informs the display device of device abnormality. Even when the determination result is not abnormal, it is possible to obtain a display indicating no abnormality from the status display device 304 by transmitting a request for confirming the device usage status from the status confirmation / control input device 305. The status display device 304 and the status confirmation / control input device 305 perform the same function even when connected to the controller 303 via the bus 108. The IRda information terminal 306 exchanges information with the current usage amount detection adapter 301 when checking the state of the device 302 without going through the controller 303. The information medium may be wired or wireless other than the bus 108.

The transmission / reception message processing unit 402 decodes the message transmitted from the current usage detection adapter 301. The device usage status control processing unit 403 manages the current flow rate change time and the current amount after the change based on the data decoded by the transmission / reception message processing unit 402, and analyzes the current flow rate abnormality and the usage status of the device. When an abnormality is recognized in the current flow rate of the device 302, an abnormality notification is output to the status display device 304. As described above, even when the analysis result is not abnormal, when a request for confirming the device usage status is received from the status confirmation / control input device 305, a display indicating that no abnormality has occurred is transmitted to the status display device 104. . Also, the device information setting unit 405 is instructed to cause a data storage unit 404 (to be described later) to perform settings for data storage, and the latest usage status of each device is output to the data storage unit 404. The data storage unit 404 stores the latest current flow rate data of the device 302. The device information setting unit 405 sets the address of the connected device, the type and number of devices.

Let B be the case. If there is no input, it is determined whether or not current change information is received (step S707), and if information is received, it is compared with the previously collected information in the data storage unit 404 (step S708). If there is a change, the process moves to step S710, and if not, the process returns to A. In step S710, the change information is requested to the device that shows the change, and the latest data is stored in the data storage unit 404 (step S711). This state is C.
[0038]
In step S707, if current change information has not been received, if the latest information collection timer has timed out (step S712), the latest information collection instruction from each device is instructed (step S713), and then the timer is restarted. Start (step S714). If the timeout is not reached, return to A.

In addition, by having a data communication circuit unit in a separate system from the line connected to the external controller, it is not necessary to check the amount of current used by the device up to the controller, and the device can check it.
[0080]
In addition, since the control means inside the current usage detection adapter can control the amount of current flowing into the device at its own discretion, people may get wet with the hand and touch the outlet part of the device at once. In a dangerous situation where current flows, current interruption processing can be performed immediately.
[0081]
Furthermore, by providing the battery unit, it is possible to charge power for driving the current usage amount detection adapter, and it is possible to distinguish whether the state in which the device does not operate is due to a power failure or a device failure.
[0082]
Furthermore, according to the current usage detection adapter application system of the present invention, it is possible to centrally manage the usage status of a plurality of home devices installed at a plurality of locations by systematization.
[0083]
Further, it is possible to detect the possibility of an abnormal load being applied to the device by determining whether or not the amount of current used by the device exceeds a certain level and notifying it.
[0084]
In addition, by calculating the device usage time, it is possible to know the actual device usage time that is difficult to grasp in real life, which can be used for comparison with the durable years and promotion of replacement of devices.
[0085]
Furthermore, by notifying that the device usage time has reached a certain level, it is possible to know the replacement time of consumable parts and the maintenance time of the device that needs to be periodically cleaned.
[0086]
In addition, it is possible to calculate the total amount of current used by multiple devices, determine the devices that can be used without exceeding the allowable power consumption, and notify the breaker when using multiple devices simultaneously. It can be avoided in advance.
[0087]
In addition, by managing the usage state and usage time of a device, it is possible to detect when the usage is different from the predicted device usage. Also, by identifying the type of device and determining the usage time, it is possible to detect the use of a dangerous device if left in use and to stop using the device in some cases .
[0088]
Furthermore, by recording the device usage status over a long period of time, it is possible to notify when the usage of the device exceeding the normal prediction is repeated.
[0089]
  As described above, the current usage detection adapter of the present inventionMeetSystem, based on the detection of the amount of current used by the device, performs device maintenance support, energy usage control, or living behavior abnormality detection, abnormal or inefficiency of the device itself, or inappropriate in the device usage method Can detect and deal with it.
