Description of the invention: [Technical field to which the invention pertains] The invention is a power supply system having: a power supply connection flat 7L 'which is connected to an electric load and serves to supply electric power to an electric load Control n (slave); and display 4, which has a master for displaying a display device of the power usage state of the power supply connection unit. [Prior Art] Conventionally, it is necessary to check the plug-in (four) power miscellaneous embedded in the wall of a room in a house or the like. There is a known display device having the power consumption of the inspection socket (for example, Japanese Patent Laid-Open Application No. 2GG2-365312). Note that the display device can display another power usage state, * not limited to power consumption. Such as the current value. The configuration of the conventional socket will be explained with reference to Fig. 15. As shown in Fig. 15, in the socket 200, the socket member 21 is provided, and the plug of the appiance (not shown) is inserted. Therein, electrical power is supplied to the negative device via the plug. Above the socket member 21G, a display device 220 is provided for displaying the power consumption supplied from the socket member 21 to the load device via the plug in a number of ways. The conventional socket 200 has the disadvantage that the size of the socket 200 has been expanded. Specifically, the socket is designed to have a standardized size. When the socket 2a is squeaked with a resizing size, the size of the display device 220 becomes larger. This _ makes it possible to visually recognize the power consumption shown on the display unit 220. Therefore, in order to improve the disadvantage, the display should be expanded. 201125255 JUUUipif However, such a configuration has another disadvantage: the size V of the socket 200 exceeds the standardized size due to the expansion of the display device. Further, in the case where the sockets 200 are installed at a plurality of places in a space therebetween, In order to understand the power consumption of the outlet 200 in each place, it is necessary to individually check the display device 22 provided for the outlet 200 (μ, therefore, this makes the inspection very troublesome. Note that another power supply connection unit embedded in the wall ( For example, the present invention aims to provide a power supply system capable of accommodating the power usage state of the power supply connection unit. The size of the power supply connection unit needs to be expanded. In the first aspect of the invention, a power supply system is provided, the work vehicle supply connection unit connected to the electric load and serving as the electric power, t a controlled controller of the load; and a page of the open day connected to the power supply connection and the remote controller by a signal line The main controller has display means for displaying the power usage state of the power supply connection unit by receiving signals from the power source two-two transmission wheels, each of which assigns 1) an address to the location In the power supply connection unit, wherein: the power supply connection unit has: ° 疋. The device 'records the power supply connection unit address 201125255 ^ouoipif recorded on the display unit; current debt measurement unit And detecting a current supplied to the power supply connection unit; and transmitting and receiving components, wherein the current value detected by the current debt detecting component and the power supply connection unit are located via the signal line Transmitting the address to the display unit, and wherein the display unit is provided with: a receiving component that receives the signal from the power supply connection unit; and a control component that is detected based on the current detecting component The current value is used to calculate the power usage state of the power supply connection unit. According to such a configuration, the display unit is configured to be separated from the power supply connection unit. Therefore, compared with the configuration of the conventional socket 200 as the display device is provided in the power supply connection unit, the power supply system can suppress the amplification of the power supply connection unit while checking the power usage state via the display device. . In addition, the power usage status of the respective power supply connection units can be checked via the display unit of the display unit. Therefore, it is possible to easily check the power usage states of a plurality of power supply connection units as compared with the conventional configuration. In a second aspect of the present invention, a power supply system is provided, comprising: a plurality of power supply connection units connected to an electric load and serving as a slave to supply electric power to the electric load; and a display unit, It is connected to the power supply connection 201125255 via a signal line and acts as a master having a display of the power supply connection unit by receiving a signal transmitted from the power supply. a display device of a power usage state, wherein an inherent address is assigned to each of the power supply connection units, wherein the power supply connection unit is provided with: an address setting component that is to connect the power supply connection unit a address recorded on the display unit; a current detecting component that detects a current supplied to the power supply connection unit; and a transmitting and receiving component that detects the current detecting component via the signal line Transmitting the current value and the address of the power supply connection unit to the display unit; and controlling a component based on The current value detected by the current detecting component is different from the power usage state of the power supply connection unit, and wherein the display unit is provided with a receiving component that receives the power supply connection The signal of the unit. According to such a configuration, the display unit is configured to be provided separately from the power supply connection unit. Therefore, the power supply system can suppress the amplification of the power supply connection unit while easily checking the power usage state via the '(4) display device, compared to the configuration in which the display device is provided in the power supply connection unit. . Further, the respective use states of the power supply connection units can be checked via the display means of the display unit. Therefore, the power usage status of multiple power supply connection units can be easily checked compared to the conventional 201125255 ^ouoipif configuration. In the above power supply system, there is provided a power supply part that supplies electric power for driving the display unit and the power supply connection unit while being connected to the display unit via a power line and connected via the display unit To the plurality of power supply connection units. The power line also acts as a signal line. The transmitting and receiving unit of the power supply connection unit may superimpose the signal and the electrical power to transmit it to the display unit. Since the power line also functions as a signal line, the wiring configuration for connecting the display unit and the power supply connection unit can be simplified as compared with the individual wiring of the signal line and the power line. In the above power supply system, the display device can be based on The current value detected by the current measuring component is used to display the cumulative amount of electrical power consumed in a predetermined period of time. In the case where the cumulative amount of electric power is displayed, the display device needs to be enlarged to some extent. In this regard, since the display unit is provided separately from the power supply connection unit, the power supply system can easily check the cumulative amount of electric power displayed on the display device. In the above power supply system, when the accumulated amount of electric power exceeds a predetermined decision value, the power supply system may interrupt electric power supplied to the power supply connection unit. By interrupting the electric power supplied to the power supply connection unit when the accumulated amount of electric power exceeds a predetermined decision value, the power supply system can prevent excessive electric power from being supplied from the power supply connection unit to the load device. In the above power supply system, when the power supply system is in a condition, the current value detected by the power supply connection unit exceeds a decision value, and the power supply system can interrupt the supply to the power supply connection unit. Electric power. The power supply system can prevent excessive current supply to the load device by interrupting the electric power supplied to the power supply connection unit when the current value detected by the power supply connection unit exceeds the decision value. Therefore, this situation makes it possible to avoid the failure of the load device due to excessive current supply to the load device. In the above power supply system, when the period in which the power supply connection unit supplies DC power (hereinafter referred to as "DC power") to the load device exceeds a predetermined decision value, the power supply system may interrupt the supply to The power supply supplies electrical power to the connection unit. The power supply system may reduce supply to the power supply by interrupting electric power supplied to the power supply connection unit when a period of time during which the power supply connection unit supplies DC power to the load device exceeds a predetermined decision value The waste of electrical power of the connection unit. Therefore, this situation saves the electrical power of the power supply system. In the above power supply system, the power supply connection unit may be a socket embedded in a wall constituting a mounting surface. This situation makes it easy to check the power usage state of the embedded outlet via the display device of the display unit. That is, such embedded sockets are often mounted in a wall near a person's foot. In this case, if the 201125255 JOUOipif device is displayed via Group II to provide the Syrian money, it becomes difficult for the lining to check the display device and thus reduce its operability. In addition, such a configuration would make the socket itself larger as described above. In this regard, since the power supply system according to the present invention can mount the display unit at the place where the recording is performed, it becomes possible to easily check the display device of the display unit. In addition, since the display device is not placed in the socket, the expansion of the socket can be prevented. In the above power supply system, the power supply connection unit may be a switch embedded in a wall. This situation makes it easy to check the power usage state of the embedded switch via the display device of the display unit, that is, when the display device is provided in the embedded switch towel, this type of device makes the switch itself h. In addition, when the power supply system has many At the time of switching, it becomes difficult to recognize the respective switches individually corresponding to the display device. In this regard, since the power supply system according to the present invention can check the power usage state of the embedded switch depending on the respective addresses of the switches, it becomes easy to recognize the plurality of switches corresponding to the display device. Further, since the display device is not provided in the switch, the expansion of the switch can be prevented. In the above power supply system, the power supply connection unit may be an extension socket connected to a socket embedded in the wall portion. This situation makes it easy to check the power usage status of the extension jack via the display unit of the look-up unit. That is, when the display device is provided in the extension socket, such a configuration makes the extension socket itself large as described above. Further, when the display device is configured to be disposed in the extension socket, it is difficult to inspect the display device. In this regard, since the power supply according to the present invention 201125255 ipxf system can mount the display unit to an easily inspectable place, it becomes easy to inspect the display unit of the display unit. Further, since the display device is not disposed in the extension socket, the expansion of the extension socket can be prevented. Other objects and features of the present invention will become apparent from the following description of the embodiments. [Embodiment] An embodiment of a power supply system according to the present invention will be described with reference to Figs. 1 through 11. First, a power supply system for supplying g power to a power supply connection unit, and a power supply connection, which is connected to a load device or the like, will be explained with reference to Figs. In a power supply system, 'power is connected to the main controller via a power line (signal line) and connected to a plurality of controlled devices (for example, a socket, a switch, and a plug P) via the main controller, thereby using the electric power of the county Lai Ying to the main controller and the controlled device. In addition, between the master and the slave, signals are transmitted and received via signal lines. Each of the controlled 11-clothes has an intrinsic address' and the master stores the native address of the respective slave. The controller superimposes its own address on the money to be transmitted to the master (4) so that the master can know which slave has transmitted the signal. In addition, the master superimposes the address of the controller on the signal to be transmitted to the slave, and the slave only receives the signal with its own address superimposed on it. # By this way, the master can manage multiple slaves together. Specifically, as shown in FIG. 1, the power supply system 1 includes: an alternating current (AC) power source Ac (power supply unit) serving as a commercial power source; ac/dc 11 201125255 JUUOipif converter 2; a display unit 3 serving as a master; And a plurality of power supply connection units, which are constituted by the socket 4 and the switch 5 serving as a controlled device.

The electric appliance 6 is connected to the socket 4, and the lighting device 7 is connected to the switch 5. The AC power from the AC power source AC is converted into DC power by the AC/DC converter 2 and supplied to the display unit 3. The display unit 3 and the socket 4 and the switch 5 perform so-called power line carrier communication. In power line carrier communication, a communication signal for transmitting data by using a high frequency carrier is superimposed on a DC voltage. Based on the power line carrier communication, the power usage states of the outlet 4 and the switch 5 such as power consumption and power usage time are transmitted to the display unit 3, and the electric power supplied to the electric appliance 6 is controlled. Further, the AC power source AC supplies electric power for driving the display unit 3, the socket 4, and the switch 5.

There is an address and the address is rotated out to the smart component 13. The current sensor 16 detects the DC current to be supplied to the plug connection part 4a via the current sensor 16 at predetermined time intervals. The current value detected by the sensor 16 (hereinafter referred to as "current value AG") is output to the control unit π. The control unit 13 outputs the address of the socket 4 and the current value AG to the signal superimposition/separation circuit 11 as In addition, the control unit 13 controls a switching element such as a semiconductor switch and a relay (not shown in Fig. 201125255^OUOipif) to control the on and off to the plug connection component such as the electric power supply. operating In the process of the system, the superimposed signals supplied from the wire connection terminal 4c to the signal superposition/separation circuit 11 are separated into DC power and communication signals by the signal superposition/separation circuit 11.

When the current sensor 16 detects the current value AG, the superimposed L number is transmitted to the display unit 3. Therefore, the 'power usage state (such as the current value AG supplied to the outlet 4 and the power consumption based on the current value AG) is displayed on the display device 3b of the display unit 3. It is to be noted that the control structure of the switch 5 is substantially the same as that of the socket 4. Therefore, the same reference numerals are given to the same components as those of the socket 4, and the description thereof will be omitted. Note that the main description will be hereinafter with the socket. The second controlled device control circuit 10a includes an operation input receiving unit 17 that detects the pushing operation of the handle 5a, and a circuit cut/close control unit 18 that turns on and off the electric power supply to the lighting device 7. 15 201125255 ouuoipif : When the handle 5a is moving, 'the operation input receiving part 17 side of the bar a push operation and output its signal to the control: =) = r with switching elements (such as semi-conducting two, 'electrical appliances) And the switching element is controlled to be cut/closed.

Therefore, the DC power supplied to the first terminal ^3c is transferred to the second terminal 3d via the main controller control circuit 2. The main control 11 control circuit 20 includes a signal superimposition/separation circuit 21 and an electric selection circuit. The device 22, the control unit 23, the storage unit 24, the clock circuit 25, the display circuit 26, and a setting interface 27. Note that the power supply circuit component has the same function as that of the power supply circuit component 12. The k-th superposition/separation circuit 21 serves as a transmission and reception unit of the display unit. Specifically, the signal superimposition/separation circuit 21 is configured to separate the power line communication supplied from the outlet 4 to the display unit 3 into a DC power and communication signal 'and superimpose the communication signal on the DC power for the superimposed letter 201125255 The JUUUipif number is supplied from the display unit 3 to the outlet 4 or the switch 5. The time circuit circuit for supplying the electric power to the electric appliance 6 and the lighting device 7 by the clock circuit 25 to each of the socket 4 and the switch 5" exceeds one at the current value AG (from the socket 4 and the two units 3) When the predetermined rolling value (decjsi〇n vaiue) al is started, the counting is started. The clock circuit 25 stops counting when the current value AG becomes equal to or smaller than the decision value AL. The decision value AL is borrowed based on the standby power demand. The value is set by the current value. The storage unit 24 stores the result calculated by the clock circuit 25 and the control unit 23, and the address transmitted from the socket 4 and the switch 5. Then, the stored result is rotated to the control unit 23 Based on the calculation result based on the current value AG and the result calculated by the clock circuit 25 based on the current value AG, the control unit 23 calculates the power consumption and power usage time with respect to each of the socket 4 and the switch 5 or both (also That is, the 'power use state.' Note that the above power calculation includes temporary power consumption and total power consumption accumulated over a predetermined period of time. Then, the above calculated result is displayed on the display device 3b. 26 acts as a circuit for driving the display device 3b. The interface 27 outputs a signal to the control unit 23 at the operation of the display device. Then the control unit 23 outputs a control signal to the display based on the signal. Wei 26. The display circuit 26 drives the display device 3b based on the control number. The display device 3b displays the addresses of the socket 4 and the switch 5. Further, by operating a touch panel, the display device 3b can assign the load name to 17 201125255 ^woipif corresponds to the socket 4 and the switch 5 of the address. Therefore, for example, when checking the power usage state of the socket for the air conditioner, the display device 3b can display the load name by inputting or calling the socket. The power usage status of the socket. That is, the values of the load name and the power usage state are simultaneously displayed on the display device 3b. Here, the DC power supplied from the first terminal 3c to the signal superimposition/separation circuit 21 and the control of the control unit 23 are controlled. Signal superposition, 4 or switch 5. In addition, the superimposed signals supplied from the socket 4 and the switch 5 are separated into 〇 by the signal superposition/separation circuit 21 (electricity and communication) The signal signal 'and then the communication signal is input to the control unit 2. The control unit 23 displays the individual use state of the socket 4 and the switch 5 or the total power usage type on the display device % based on the communication signal. In the socket 4 and the switch 5, the on/off_control of the electric power supply for the subsequent electric appliance 6 and the illuminator 7 is performed by the above calculation result of the i control unit 23. Hereinafter, the socket is arranged, However, similar control is also performed in the switch 5. First, the electric power for the electric appliance 6 is supplied with reference to Fig. 6: power supply: ON and OFF control should be continuously exceeded in the control unit 23. 1 determines the decision value is '15 (4)) and continues - when the predetermined time is fine (for example, 〇 1 second), = turn to the socket 4. Note that the user can freely perform a predetermined period of time. 18 201125255 For example, as shown in Fig. 6, when the electric appliance 6 connected to the outlet 4 is activated (time T1), the current value AG rises. It is assumed that the current value AG consumed in the electric appliance 6 reaches the decision value (15 (A) in this embodiment) at time T2. If the electrical appliance 6 continues to be used under these conditions, the current value AG will exceed the decision value AJ. The electric power supply β for the electric appliance 6 from the outlet 4 is disconnected from the time T3 after the predetermined time T3, which prevents the socket 4 from being overheated, because the excessive current is higher than the decision value AJ continuously supplied to the electric power. Caused by appliance 6. The actual program flow of the power supply control by the control unit 23 as shown in Fig. 6 will be explained with reference to Fig. 7'. Note that the program is repeated at a predetermined interval. As shown in FIG. 7, in step s1, the control unit 23 = checks whether the detected current value 仏 is equal to or greater than the decision value aj. When the electric binary AG is equal to or greater than the decision value AJ (step $3Γ42: check if this condition is maintained for two periods, ^ or longer)::::::: The supply control, the base 4 to the electric appliance 6 to the period of time to perform the on and off self-insertion clock circuit 25, the suspect element 23 calculates the elapsed time TG _ (four) (four) between the TG.

In the case where the electric device 6 and the device 7 are disconnected, the elapsed time TG passes through the sum of the time (10). Note that the user can freely set the decision value TJ by the touch panel of the second cumulative display=. 1 D For example, as shown in Fig. 8, assuming that the electric cooker 6 is repeatedly turned on and _ on, and in the case of the third operation_phase decision value η, the clock circuit 25 counts the time at T11 and The elapsed time from T11 to Τ12 is output to the control unit 23 as the inter-intermediate TG1. Similarly, the clock circuit outputs the output unit 23 by taking the elapsed time of Τ14 to Τ15 as the second elapsed time TG2. At this time, the cumulative value TGA (TG1 + TG2) of the first elapsed time TG1 and the second elapsed time ^ is smaller than the decision value TJ. Subsequently, the clock circuit 25 纟 T17 _ counts the time and accumulates the third elapsed time TG3. When the accumulated value TGA (TG1 + TG2 + TG3) reaches the value ^ at m, the electric power supply to the electric appliance 6 is turned off. Note that the accumulation time counted by the clock circuit 25 and the instruction to disconnect the electric power supply can be reset for a predetermined period of time (e.g., 24 hours). Referring to Fig. 9, a specific procedure of power supply control as shown in Fig. 8 will be explained. The procedure is repeated at a predetermined interval, and the cumulative value TGA of the elapsed time TG for each count is reset. As shown by 9, as shown in 9, in step S2, the control section 23 checks whether the current value AG is equal to or larger than the decision value AL. When the current value AG is equal to or greater than 20 201125255 to the discreet value AL (YES in step S20), the clock circuit 25 starts counting the time in step S2i. Subsequently, in step S22, the control section 23 checks whether or not the elapsed time TGX (which is the time elapsed since the self-clock circuit started counting the time) is smaller than the decision value TJ. When the elapsed time TGX is smaller than the decision value TJ (YES in step S22), the control section 23 determines that the electric power supply should be maintained, and checks in step S23 whether the current value AG is smaller than the decision value a1. On the other hand, when the elapsed time tgx is equal to or larger than the decision value TJ (NO in step S22), the electric power supply is turned off in step S27. When the current value AG is equal to or larger than the decision value AL (NO in step S23), the control section 23 determines that the electric appliance ό is in use, and continues counting the time. On the other hand, when the current value AG is smaller than the decision value a1 (YES in step S23), the control section 23 determines that the use of the electric appliance 6 has been terminated, and stops counting the time in step S24. The lapse/time is calculated, and the elapsed time TGY is calculated in step S25. Next, in step S26, the control section 23 checks whether the elapsed time TGY is equal to or larger than the decision value TJ<3. When the elapsed time is equal to or larger than the decision value TJ, the electric power supply is turned off in step S27. On the other hand, when the elapsed time TGY is smaller than the decision value TJ, step S2 is performed. In this case, each of the respective elapsed times TGX and TGY for comparison with tj is defined by accumulating the cumulative value TGA of the previous elapsed time TGY counted in the previous step. Looking at Figure 10, the power supply control of the control unit 23 will be explained, which is based on the amount of electric power supplied from the outlet 4 to the electric appliance 6 to control the electric power supply to the electric appliance 6. When the electric appliance 6 is connected to the outlet 4, the current value AG is increased to exceed 〇 (amperes). On the other hand, when the electric appliance 6 is removed from the socket 4, the current value AG is reduced to 0 (amperes). The control unit 23 calculates the total value AGT of the electric power consumed in the electric appliance 6 based on the current value AG described above.
