Description

The present invention relates to a rotating power supply system for charging a plurality of information devices and the like using a rechargeable battery.

Education using ICT has started in elementary and junior high schools, but as of March 2019, PC terminals prepared for each school (tablet terminals, laptop PCs, etc. that are lightweight and have a built-in rechargeable battery). The national average of the number of children is only one in 5.4 children. For this reason, the supplementary budget for the 1st year of Reiwa, which was approved by the Cabinet in December 2019, included a move toward the realization of the so-called GIGA school concept of deploying one PC terminal per student (5th, 6th, middle). 1). Furthermore, the supplementary budget for the 2nd year of Reiwa was established in April 2020, and it was decided to advance the terminal maintenance support that was planned to be achieved in the 5th year of Reiwa (small 1-4, middle 2, middle 3). It is unlikely that all the students enrolled in the school will use the PC terminal at the same time, but the situation is about to be such that one class of students will use one PC terminal at the same time to participate in the class. If there are about 40 students enrolled in one class, at least the same number of PC terminals will be prepared. Before class, the rechargeable battery needs to be charged enough to be able to operate during class hours, but in conventional schools, power outlets for the number of students are not set up in the classroom. Therefore, a rechargeable storage storage that stores PC terminals and has power outlets for the number of PC terminals inside has been proposed and is commercially available. Demand is increasing as schools are purchasing / preparing storage for storing and charging PCs, and various companies are trying to enter the market. In Patent Document 1, it is possible to indicate that charging is complete when charging is completed and information devices such as PC terminals can be used without the need for special outlets or wiring work for wiring. A control device and a storage system in a storage for storing equipment are provided.

Further, a timekeeping means is provided for each group corresponding to each of the plurality of the groups, and each of the timekeeping means measures the cumulative energization time of each group and reaches a preset value for the cumulative energization time of all the groups. When the current value flowing during charging of each group reaches a predetermined value, charging is completed. In addition, charging to the information equipment group of the corresponding group is started according to the charging order for each group determined in advance, and the measurement result of the charging current for each group of the current measurement circuit is used to determine the individuality of each group according to the predetermined charging order. Controls to switch from energization to simultaneous energization of multiple groups including groups in the following order. Therefore, a current measurement circuit is required for each charging group, and cumulative charging time must be measured and recorded for each charging group, which requires a large number of equipment components and is costly.

Hereinafter, the present invention will be described with reference to embodiments, but the “current” used in the description can be read as “electric power”. Since the voltage of electricity provided for general commercial use takes almost a predetermined value, the object of the present invention can be achieved even if it is composed of electric power represented by the product of current and voltage.
The present invention is not limited to the embodiment.

<Outline of Embodiment 1> Claim 1 (basic)
The rotation power supply system of the first embodiment is a power supply group that is connected to an external power source such as an outlet installed on the wall of a school classroom, receives power, and is supplied with power from the rotation power supply system and the power supply outlet of the rotation power supply system. The total supply current value of the charging current of the PC terminal etc. connected for charging is measured and acquired. A group switch unit (C) that can turn on / off the power supply is provided for each of the plurality of power supply outlets that supply power to the power supply group. Based on the held order information, the new power supply outlet selection operation judgment unit (F) determines the execution of the selection operation that sequentially selects and turns on the power supply outlet, and the group switch unit (F) so as to execute the rotation process. C) is controlled by the rotation execution unit (G).

FIG. 23 shows a schematic view of a PC terminal or the like using the rotary power supply system of the present invention (a tablet terminal, a laptop PC, or the like that is lightweight and portable and has a built-in rechargeable battery) as viewed from the left side of the storage. The storage storage (2300) is installed near the wall surface (2316) of the facility such as a school, and the rotation power supply system (2301) receives power from the power outlet (2309) on the facility side, and the entire storage storage (2300) is received. Power is supplied to each part. The storage cabinet (2300) is supported on the floor surface (2315) of the facility by lockable wheels (2308) provided on the bottom surface of the housing. In addition to the wheels, an adjuster bolt for temporary fixing may be provided on the bottom surface. Open the door (2303) of the storage that can be seen and locked inside from the window in which the transparent acrylic plate is fitted, and enter the space partitioned by the support plate (2317) on the internal shelf plate (2305). A tablet terminal (2311) held upright is stored. A charging cable (2312) is connected to the connection terminal of the tablet terminal (2311), and is connected to the AC adapter (2313). The AC adapter (2313) is plugged into the power strip (2304) through the hole in the partition plate (2302) with a hole for passing cords, etc., installed in the back of the storage room where the tablet terminal (2311) is stored. , It is ready to be charged. In FIG. 23, one power strip (2304) is provided with eight power supply outlets as described on the right side of the storage cabinet (2300). In the schematic diagram of the storage, eight power outlets are lined up from the front to the back. In addition, the reason why the main body storage part such as PC and the AC adapter storage part are separated by installing a partition plate as shown in Fig. 23 and made into a separate room is to prevent the wiring of multiple AC adapters from being mixed. It is based on the example of the standard specifications for the charging storage stored in the "Standard Specifications for Realizing the GIGA School Concept" issued by the Ministry of Education, Culture, Sports, Science and Technology on March 30. The tablet is stored vertically according to the above specification example.

In the example of FIG. 23, six power strips (2304) are arranged in the storage storage (2300) and are inserted into the power supply outlets on the side surface of the rotation power supply system (2301). A service outlet (2306) is arranged in the upper part of the back surface of the storage (2300). Further, the facility LAN outlet (2310) near the facility power outlet (2309) on the facility wall surface (2316) and the rotation power supply system (2301) are connected by a LAN cable. This is used for monitoring the status of the rotation power supply system (2301) via the wired LAN line in the facility, rewriting and updating the settings, and the like. Although not explicitly shown in the figure, a wireless LAN transmission / reception system is provided in the storage (2300), power is supplied from the rotation power supply system, and the LAN communication cable is connected to the rotation power supply system (2301). Similarly, it may be useful for monitoring the status of the rotation power supply system (2301) and rewriting and updating the settings. A service LAN outlet (2307) may be arranged in the vicinity of the service outlet (2306) above the back surface of the storage (2300). By connecting the service LAN outlet (2307) to the facility wired LAN line, for example, a teacher's PC can be preferentially connected to the facility network line. It is assumed that the PC terminals and tablet terminals used by children and students will use wireless LAN. When projecting a video of a streaming distribution with a heavy line load or a video call through a WEB camera with a remote location with a projector as part of the class, if the teacher's PC is connected to a wired LAN, communication will be possible. This is preferable because it makes it easier to secure a band. A projector used for image projection can be placed on the top plate of the storage cabinet, and a service outlet can be used as its power source. The service outlet may have multiple power outlets instead of one.

The rechargeable battery mounted on the PC terminal or tablet and the AC adapter generate heat slightly during charging. When about 40 devices are stored and stored, all the devices may not be charged at the same time due to the rotation power supply, but the atmospheric temperature in the storage rises during the charging operation. For example, the bottom surface of the storage can be made of a mesh steel plate, and when the temperature sensor inside the storage detects that the atmospheric temperature has reached a predetermined temperature or higher, the exhaust fan provided on the upper back surface or the like can be turned on to exhaust heat. Alternatively, although not explicitly shown in the figure, it is preferable to provide a liquid crystal display, an LED number display, an LED lamp, or the like as a display for displaying the supply current value (or power value) and the power supply outlet number currently being supplied. Alternatively, when the door of the storage is opened, the lighting that illuminates the inside of the storage can be turned on as needed. When providing a power source for interior lighting, power should be supplied from a service outlet series that is not subject to rotation in the rotation power supply system. LED lighting with low power consumption and long life is preferable. In addition to the general commercial AC 100V, it is convenient to have a DC output of about 5V or 12V as a service outlet. Power for driving temperature sensors and exhaust fans, display for display, LED lighting, etc. are also supplied from the power supply of the rotary power supply system and are subject to current or power monitoring.

FIG. 24 shows an outline of the configuration of the rotation feeding system mounted on FIG. 23. Inside the metal case (2400), power supply unit / cutout / current meter (2401), relay (2402), power supply relay control (2403), MPU / crystal oscillator / various memories (2404) arranged on the printed circuit board. ), Various communications (2405), LED control / Dip switch (2410), power supply outlet (2406), service outlet (2407), external power connection port (2408), communication cable outlet (2409), etc. There is. For the external power supply connection port (2408), for example, an IEC60320 compliant C14 type inlet can be used. Since the power cord can be removed, it is convenient because it does not get in the way when moving the storage to another classroom. The cutout of the power supply unit, cutout, and ammeter (2401) is an excess of the minimum maximum rated current among the members that make up the wiring of the facility side power supply, the rotation power supply system, and the storage to the rotation power supply system. It is a device that turns off the current supply in order to prevent damage to the equipment and smoke and ignition accidents due to heating when current is about to flow. At the same time, it is more preferable to have measures against lightning surges. The relay (2402) may be an electromagnetic relay, a MOS FET relay, or a switch of a type that can be turned ON / OFF by remote control. Various communications (2405) are for I2C communication used for communication with the current meter of the power supply unit, cutout, and current meter (2401), LAN communication for connecting to the in-facility wired LAN or wireless LAN input / output device, and other input / output. Controls input / output such as serial communication such as RS232C. LED control ・ Dip switch (2410) controls the lighting of the LED that shows the operating status of the rotation power supply system, displays the power supply outlet during power supply, and turns off the power supply to multiple power supply outlets individually. It is used to switch the operation mode, the switching order when the rotation process is executed, and the timer cycle setting when the rotation is executed. The DIP switch can also be configured to set a current value that serves as an ON / OFF determination criterion for each power supply outlet for executing rotation processing, which will be described later. This current value can also be configured to be set from a PC terminal or the like outside the rotation power supply system through a LAN line.

In the example of FIG. 24, six power supply outlets (2406) are shown, and as in the example of FIG. 23, power strips are connected to the power supply outlets one by one for use. The cord may be extended to the outside of the metal case (2400) and directly connected to the power strip without the intervention of the power strip. In the example of FIG. 23, the power strip corresponds to the power supply group. The power supply outlet of the power strip may be a USB terminal instead of a general AC 100V outlet, or may have both.
Further, instead of the power strip, it may be branched to a power supply outlet having a desired number of fractions. If it is branched into a single power supply outlet, it has the effect of increasing the degree of freedom in the layout design of the power supply outlet in the storage. In FIG. 24, a power supply outlet (2406) is attached to the side surface of the metal case, but a cord having one power supply outlet at the end corresponding to the number of power supply outlets (2406) is taken out from the metal case (2400) and stored. It may be stretched and dispersed in the refrigerator. The purchaser of the storage can purchase and install a commercially available power strip for the required number of minutes.

Since the standard number of children in elementary and junior high schools is 40, it is preferable that one storage unit equipped with a rotation power supply system can charge the PC terminals used by 40 children. More preferably, it is better to have at least one power supply outlet capable of preferentially charging the teacher's PC terminal to be instructed. Since the maximum rating of a general outlet is 1500W (15A), the wall outlet in the classroom usually has the same standard. Therefore, the upper limit of the power supplied to the rotation power supply system is 1500 W. The electric power when charging a general tablet terminal using an AC adapter is about 10 W to 16 W. When the above tablet is connected to a power strip having a plurality of power supply outlets for charging, for example, in the case of a power strip having eight power supply outlets, 16W x 8 = 128W, and when the power supply is 100V, it is 1.28A. In the case of a rotating power supply system that supplies power from a power supply outlet that supports 6 power strips equipped with 8 power supply outlets for one class of around 40 people, a tablet with a charging power of 16 W to all 48 power supply outlets. When these are connected, 16 (W / piece) x 48 (pieces) = 768 (W). It is below the maximum rated power of 1500W. However, since the charging power of a general notebook PC is 45 W / unit, the same calculation shows that 45 × 48 = 2160 W, which exceeds the maximum rated power. Therefore, not all devices can be charged at the same time, and it is necessary to supply power by rotation.

The rotation execution unit (G) controls the selection and switching of the power supply outlet that supplies power for charging, but in the description of the first embodiment, it is controlled by a device having a configuration similar to that of a PC as shown in FIG. 3 to be described later. Is assumed. However, the configuration is not limited to this, and control may be performed by a logic circuit incorporated in the FPGA or ASIC. Regardless of the configuration, the switch operation may be performed by an electromagnetic relay or a MOS FET relay, or by using a switch of a method that can be turned ON / OFF by remote control by another method. Further, as in the embodiment described later, a device that wants to be preferentially supplied with power for charging a teacher's PC terminal may be separately provided with a service outlet that is a power supply outlet configured so as not to be included in the target of rotation. It can also be used to turn on a projector (generally about 300W) for explaining lessons while continuing to charge the equipment for children. Details will be described later, but even if a load is suddenly added to the power supply outlet of the power supply group that supplies power from the power supply outlet that is the target of the rotation power supply or the service outlet during the rotation power supply for charging, the target of the rotation power supply is adjusted and changed. And the order can be changed to continue power supply.

In the present specification, "power supply ON", "power supply ON", "power supply", "power supply OFF", "power supply OFF", "power supply stop", "power supply interruption" to the power supply outlet or power supply group. In the case of such a notation, even if it is not specifically stated, it includes turning on / off each switch in charge of the power supply outlet or the power supply group.

<Embodiment 1 Functional Configuration>
FIG. 1 is a diagram showing a functional block of the rotation feeding system of the present embodiment. As shown in the figure, the rotary power supply system (0100) of the first embodiment includes a power supply unit (A) (0101), a group switch unit (C) (0102), a rotation number execution unit (G) (0103), and the rotation power supply unit (G) (0103).

Each functional block constituting the rotation feeding system described below may be realized by hardware, software, or hardware and software. Specifically, if a computer is used, a CPU, main memory, GPU, image memory, graphic board, bus, or secondary storage device (hardware, non-volatile memory, storage medium such as CD or DVD, and them). Input devices such as operation buttons used for inputting information, keyboards, mice, touch panels, electronic pens used exclusively for the purpose of touching touch panels, joysticks or pointer position input devices similar to joysticks, etc. Hardware components such as external peripheral devices, interfaces for the external peripheral devices, GPS reception interface, GPS computing device, gyro sensor, acceleration sensor, rotation detection sensor, signal processing device for these sensors, camera, image file Biometric devices such as processing circuits, communication interfaces, bar code readers, POS terminals, face recognition devices, encryption devices, fingerprint authentication devices, palm print authentication devices, retinal authentication devices, and driver programs for controlling those hardware.

Instructions to control the are generated. Here, the above program may be realized as a plurality of modularized programs, or may be realized as one program by combining two or more programs.

Further, the present invention can be partially configured as software. Further, a storage medium in which such software is recorded is naturally included in the technical scope of the present invention (not limited to this embodiment, but the same throughout the specification).

<Explanation of Embodiment 1 Configuration>
<Embodiment 1 Power supply unit (A) (0101)>
The power supply unit (A) (0101) is configured to have a plurality of power supply outlets for supplying power to a power supply group having a plurality of power supply outlets. The power supply outlet and the power supply outlet may be a general two-hole type for home use, but a three-hole type with a ground electrode is preferable. One power supply group and a power supply outlet have a one-to-one correspondence, but the power supply group connected to the power supply outlet has a general power strip (multiple power supply outlets are arranged on the opposite side of the power supply cord with a power plug on one end). It corresponds to the above, and it is used by inserting the plug into the power supply outlet. One plug may be branched into a plurality of power strips. Further, instead of the power strip, one that branches from one plug to a plurality of power cords and reaches one outlet for each may be used. The power supply outlet of the power tap may be a USB terminal type instead of a general commercial AC 100V power supply outlet, or may be provided with both an AC 100V outlet and a USB terminal. In the examples of FIGS. 23 and 24 described above, the case where the number of power supply outlets is six has been described, but the effect of the present invention can be obtained if the number of power supply outlets is not limited to six. If there are few such as two, the rotation power supply effect is small, and if there are many, there is a demerit of cost increase due to an increase in the number of parts.

<Embodiment 1 Group Switch Unit (C) (0102)>
The group switch unit (C) (0102) is configured to have a group switch for turning on / off the power supply for each at least one or more power supply outlets. The group switch is arranged for each power supply outlet for supplying power to at least one power supply group, and operates to turn on or off the power supply to the power supply outlet in charge by the control of the rotation execution unit (G) (0103) described later. do. The group switch itself may be provided near each power supply outlet in charge of each, or another rotation execution unit (G) (0103) or a new power supply outlet selection operation determination unit (F) (F) slightly separated from the power supply outlet. It may be arranged in the vicinity of a package integrated with 0106), an order information holding unit (D) (0105), a new selection stop threshold current value information holding unit (E) (0107), and the like. The switch may be turned on and off by using an electromagnetic relay or a MOS FET relay, or by operating a contact with a motor to switch the switch. It is not limited to the embodiment. In the embodiment of the sixth embodiment described later, the power supply outlet is not provided, and the power supply group having a plurality of power supply outlets is directly connected to the group switch by a cord.

<Embodiment 1 Rotating Execution Unit (G) (0103)>
When a predetermined condition is satisfied during power supply execution, the rotation execution unit (G) (0103) stops power supply to at least a part of the power supply outlets being power supply based on the held order information.

Based on the total supply current value information acquired in step 1 and the new selection stop threshold current value information (Ia), it is determined whether to cancel the selection of the new outlet during the power supply outlet selection operation, and the new selection stop threshold current value information (Ia) or higher. In the case of, in the new selection non-execution substep (h) (S1717) in the rotation execution step (g) (S1710), all the power supply outlets are selected as a result of selecting the power supply outlets that are not supplying power. In the case of a new power supply outlet selection operation determination step ( f) The process of returning to the back of (S1707) is performed, and when the power supply is to be continued in other cases, the process of returning to the front of the new power supply outlet selection operation determination step (f) (S1707) is performed. This is an operation method for causing the rotation power supply system to execute such a series of processes.
When the new selection cancellation threshold current value information (Ia) is larger than the total supply current value information, there are two criteria for the case where the new selection cancellation threshold current value information (Ia) is equal to or greater than the new selection cancellation threshold current value information (Ia). However, either condition determination method may be used to operate the rotary power feeding system of the present invention.
In the power supply stop processing control sub-step (p) (S1712) in the rotation execution step (g) (S1710), the total supply current value information regarding the power supply stop processing of the power supply outlet during power supply is the selection process stop threshold current value for power supply stop. Although it is assumed that it continues until it becomes less than or equal to the information (Ic), it may be continued until it becomes less than the power supply stop selection process stop threshold current value information (Ic).

<Outline of Embodiment 7> Claim 7 (rotary power supply service outlet)
The seventh embodiment is based on the rotation feeding system of any one of the first to sixth embodiments, and the feeding unit (A) further has a service outlet group (S) provided with at least one feeding outlet, and the total supply current is provided. The value information acquisition unit (B) acquires the total supply current value information, which is the information of the total supply current value including the service outlet group (S), and the rotation execution unit (G) excludes the service outlet group (S). It is configured to execute the process of starting and stopping the power supply to the power supply outlet.

<Structure of Embodiment 7>
FIG. 19 shows a functional block diagram of the rotation feeding system of the seventh embodiment based on the sixth embodiment. As described above, the service outlet group (S) (1916) is further configured in the power feeding unit (A) (1901) with respect to the sixth embodiment. Since the same is true for the sixth embodiment except for the service outlet group (S) (1916), only the service outlet group (S) (1916) will be described below. The same effect can be obtained by using any one of the first to fifth embodiments as a basis.

<Explanation of Embodiment 7 Configuration>
<Embodiment 7 Service Outlet Group (S) (1916)>
In the "service outlet group (S)" (1916), the power supply unit (A) further has a service outlet group (S) equipped with at least one power supply outlet, and the total supply current value information acquisition unit (B) has. , The total supply current value information including the service outlet group (S) (1916) was acquired, and the rotation execution unit (G) excluded the service outlet group (S) (1916). , It is configured to execute the process of starting and stopping the power supply to the power supply outlet.
The total supply current value information in the power supply unit (A) having multiple power supply outlets includes the current value of the service outlet group (S) as described above, and the group switch to each power supply outlet is turned on when the rotation process is executed. It affects the judgment of OFF. When a device with large power consumption (current) is connected to the service outlet group (S) (1916), the power supply outlet is used for the new selection stop threshold current value information (Ia) and the power supply stop threshold current value information (Ib). The current that can be supplied to the power supply will be reduced by that amount, and the time required to charge the device during charging will increase.
If a device with power consumption exceeding the maximum rated current is connected to the service outlet group (S) (1916), a cutout is provided between the external power supply and the total supply current value information acquisition unit (B) (1904). If this is the case, it is possible to prevent damage to the rotating power supply system, the connected PC terminal, and the like.

Since the processing flow and the hardware configuration are the same as those in the sixth embodiment except that the service outlet group (S) is provided, the description thereof will be omitted.

<Outline of Embodiment 8> Claim 8 (having a plurality of power strips for rotating power supply)
The eighth embodiment is based on the rotary power feeding system according to any one of the first to seventh embodiments, and the feeding unit (A) has a plurality of feeding groups provided with a plurality of power feeding outlets in place of the feeding unit (A). It is configured to have.

The configuration of the eighth embodiment based on the first embodiment is shown in FIG. 20b. Similar effects can be obtained based on the second to seventh embodiments. A power strip (2008), which is a power supply group provided with a plurality of power supply outlets, is configured to be directly connected to a relay switch (2009) unit. If the number of power supply outlets provided by the power strip (2008) is predetermined, the member of the power supply outlet (2015) in FIG. 20a is not required, so that the parts cost and the processing fee can be reduced.

The power supply outlet may be a general two-hole type for home use, but a three-hole type with a ground electrode is preferable. In the power strip, which is a typical example of the power supply group, the power strip in FIG. 20b ( It is better to arrange them in the direction shown in 2008). Among the AC adapters for charging information terminals, there is also a type of product in which the AC adapter part and the insertion part to the power supply outlet are integrated, and they are arranged in the direction shown in Fig. 20b and the direction turned 90 degrees. In this case, it interferes with the adjacent power supply outlet, and the power supply outlet cannot be used closely. Alternatively, every other power supply group may be arranged so as to be on the opposite side to one side of the power supply group so that the distance between the power supply outlets on one side is wider than that on one side. One power supply group may be configured to be branched into a plurality of power strips, or a form in which one power strip is branched into a plurality of cords having one outlet at the end instead of the power strip, the effect of rotary power supply can be similarly obtained. can get. It is preferable to avoid facing the power outlet side upward as much as possible. This is because there is a concern that dust may enter the outlet of the power supply outlet, or if water or the like is spilled on the top plate of the storage and hits the heavy rain power outlet, it may cause a short circuit. The power supply outlet of the power tap (2008) may be an outlet for general commercial AC 100V, a USB type terminal, or both may be provided. This is because some mobile terminals on the market have a USB-type terminal for connecting the AC adapter and the charging cable.

The configurations of the first to seventh embodiments correspond to FIG. 20a. A power supply outlet (2015) is provided between the power strip (2008) and the relay switch (2009). The power supply outlet (2015) is connected by providing a plug (male type) at the end of the power tap (2008) and the shape of the outlet (female type), and power is supplied to the power tap. In this configuration, the power strip (2008) can be changed without rewiring. Therefore, for example, the number of power supply outlets provided in the power strip (2008) connected to the power supply outlets n = 1 and n = 2 may differ between the two.

In the rotation power supply system, new selection stop threshold current value information (Ia), order information, and although not shown in FIGS. 20a and 20b, power supply stop threshold current value information (Ib), power supply stop selection process stop threshold current value. Information (Ic), timer information, etc. are retained in the system. It can be configured to edit, delete, and register information remotely from an external management terminal via a communication line. 20a and 20b show an example using a wired LAN. Other general communication lines such as wireless LAN, mobile phone line, and telephone line may be used. In the figure, the communication unit controls the communication between the rotation power supply system and the outside, and the ID holding unit holds the ID number assigned to the rotation power supply system. The ID number may be set by the user, or may be set by a manufacturer other than the user and used by the user. Even if it is set by the user, a unique number that can be set and referenced by the manufacturer or an authorized person may be held separately. The ID number is used to specify the target rotation power supply system when rewriting each of the above information via the communication line. The control unit receives instructions from the external management terminal through the communication unit, accesses the corresponding function, and rewrites the corresponding information. The status information holding unit holds status information in which the operation history and operating status of the rotary power supply system and the setting status information of each information are associated with the time information.

FIG. 20c shows the configuration of the management terminal outside the rotation power supply system. The management terminal is used by a user such as a school who has introduced the rotation power supply system of the present invention, or / and is used by a management company entrusted with management by the user such as a school. The management terminal is an input reception unit that allows users and management companies to grasp the status of the rotation management system and receive instruction information for rewriting information, and an address such as the ID number or / or IP address of the rotation power supply system that is being managed. Obtained from an address acquisition unit that acquires information, an ID storage unit that stores and retains the acquired address information, a control command holding unit that holds control commands sent from the administrator terminal to each rotation power supply system, and each rotation power supply system. It consists of an information retention storage unit that stores and retains status information, and a communication unit that communicates with the rotation power supply system to be managed via a LAN line or the like.

For users of schools that have introduced and are using the rotation power supply system, for example, the teacher in charge of each class has the authority to edit only the settings of the rotation power supply system of the class that he / she is in charge of. It is preferable to give multi-layered authority, such as expanding the scope of authority each time the system is increased, and allowing faculty members or full-time staff assigned to system management work to edit information on all rotating power supply systems. Furthermore, when a user such as a school outsources maintenance and management of a rotation power supply system to a management company outside the school, the management company acquires and browses each state information from the state information holding unit in each rotation power supply system. It is possible to deal with abnormalities. For example, it is possible to recommend maintenance and inspection or parts replacement when an abnormality occurs at night or on a holiday, or when the operating time is close to the expected occurrence of a failure in the near future. The management company can also edit each information of each rotation power supply system on behalf of the management company.

<Operation example of rotation power supply system>
In order to explain the operation of the rotary power feeding system, an operation example of the rotary feeding system having the configuration of FIG. 20b will be described with reference to FIG. 21. Even when the configuration of FIG. 20a is used, the same explanation can be made by replacing the “power supply group” with the “power supply outlet that supplies power to the power supply group”. In the following, for the sake of simplification of the explanation, it is assumed that a PC terminal of the same model is connected to each power supply outlet for charging.

The table of FIG. 21a shows the current value of each power feeding group during operation and the transition of ON / OFF of each group switch. In the table, 〇 indicates switch ON and × indicates switch OFF.

FIG. 21b is a graph showing the transition of the total current value at the time when each timer elapses, and the figure below the graph shows whether or not each power supply group is supplied with power (ON) or not (OFF). It is simply illustrated. 15.0A shown on the vertical axis of the graph of FIG. 21b indicates the maximum rated current value of the device, 13.0A (Ib) indicates the power supply stop threshold current value, and 10.0A (Ia) indicates the new selection stop threshold value. The current value is shown, and 4.0 A (Ic) indicates the power supply interruption selection process stop threshold current value. In the following description, they are referred to as Ib, Ia, and Ic.

FIG. 21c shows an outline of the time change of the current value when charging one PC terminal. Charging the rechargeable battery generally proceeds while the voltage increases in the constant current mode first, and then gradually decreases in the constant voltage mode. The PC terminal used in the explanation this time requires a current of 0.5 A / unit in the constant current mode at the start of charging, but the current gradually decreases after the charging progresses.
At the start of charging, among the 6 power supply groups (each having 8 power supply outlets) configured in the rotary power supply system, No. In the power supply group of 4, only 6 power supply outlets are connected, No. Only 5 power supply outlets are connected to 5, and all 8 power supply groups are connected.

The figure below the graph of FIG. 21b shows the order of ON / OFF of the group switch. In this example, the numbers proceed in ascending order of 1, 2, 3, 4, 5, and 6, and No. The order is loop-like, such as returning to 1 after 6. It is sufficient that the order of the rotation numbers is fixed, and the above-mentioned order is not always used.

(1) At the start As shown in the "Start" column in the table of FIG. 21a, No. 1 is turned on. The current value reaches Ic at 4.0 A, but it does not reach Ia, so No. 2 is also turned on. Since the total supply current value is 8.0 A, No. 3 is turned on. Since it exceeds Ia and is less than or equal to Ib, the new selection is canceled and the power supply to the selected power supply group is not turned off. No. The timer starts when the power supply is turned on for 1, 2 and 3.

(2) After 1 lapse of a predetermined time of the timer As shown in the "after 1 lapse" column of Fig. 21a, the No. 1 in the earliest order of the power supply group. Turn off 1. The total supply current value is 8.0 A, which is not less than Ic. 2 is also turned off. Since it reached 4.0 A and reached Ic, the work of turning off the power supply group during power supply is completed. No. 3 is a state in which power supply is being continued. Next, the work is switched to turning on the power supply group that was not supplying power.
As shown in the right column of "after 1 elapse" in the table of FIG. 21a, the No. Turn on from 4. No. When 4 is turned on, 7.0A, No. When 5 is also turned on, it becomes 9.5A. No. When 6 is turned on, it becomes 13.5A, which exceeds Ia, so No. The new selection after 6 is canceled, but Ib has also been exceeded, so No. Turn off 3. Therefore, the current value is 9.5A, which is lower than Ia, but No. With 4, 5 and 6 turned on, start the timer.

(3) After 2 lapses of the timer predetermined time As shown in the "after 2 lapses" column of the table of FIG. 21a, No. Power supply is turned off from 4. No. When the two power supply groups 4 and 5 are turned off, the power supply OFF work is stopped because the power supply becomes 4.0 A below Ic.
As shown in the right column of the column "after 2 elapses" in the table 21a, No. No. 6 was supplied with power but was not supplied. Turn on 1. Since the total supply current value is 8.0 A, which is smaller than Ia, the following No. Power 2 is turned on. Since it is 12.0 A and exceeds Ia, No. The work of turning on the power supply group after 3 was stopped, and No. The timer is started with the power supply ON for the power supply groups 6, 1 and 2.

(4) After the timer predetermined time k + l has elapsed Even after the timer predetermined time 2 has elapsed, the rotation power supply is continued while monitoring the total supply current value in the same manner. After the timer predetermined time k + l elapses, charging enters the constant voltage mode, and the current value gradually decreases with time. Therefore, the current value required for charging each power supply group is decreasing as compared with the case after 2 elapses.
As shown in the column "after the elapse of k + l" in the table of FIG. 21a, immediately after the elapse of k + l, No. Power was supplied to the power supply groups of 3, 4, 5, and 6, and 6.8 A was flowing. No. 1 in the earliest order When turning off in order from 3, No. It falls below Ic when it is turned off to 4.
As shown in the right column of the column "after k + l elapses" in the table of FIG. 21a, the No. When 1 is turned on, it is 5.3A, which is smaller than Ia. Continue to No. When 2 is also turned on, it becomes 7.3A, which is still smaller than Ia. No. which was supplying power but was once turned off. Even if 3 is turned on again, it is 9.3A, which is still less than Ia. Therefore, the remaining No. When 4 is turned on, it exceeds 10.5 A and Ia, but it is less than Ib, so the timer is started with all the power supply groups turned on.

(5) After K + l The timer started with all power supply groups turned on. If the Ib is not exceeded due to the addition of a PC terminal during power supply, the charging current is getting smaller even when all the power supply groups are ON, so the operation of starting the timer again is repeated. As described above, if the PC terminal to be charged is added or a device with high power consumption is connected to the service outlet and the power consumption does not exceed Ib, the power supply ON / OFF of the power supply group is not reviewed and the entire power supply group is sent. Continue to supply power. However, as described above, it is determined whether or not power is supplied to all the power supply groups and whether or not the total supply current value information is Ib or more at predetermined time set by the timer. Normally, charging is performed from the evening when one day's lessons are completed to the next morning, so even if power supply continues as it is, there will be no significant overcharging. Depending on the PC terminal or tablet product, there is also a product in which the main body or the AC adapter has an overcharge prevention function, and such a product is still preferable.

Since the information on the total supply current value is constantly acquired and monitored, if a load is added to the power supply group or service outlet during power supply and the total supply current value is Ib or more, the following processing is performed. You may. As shown in FIG. 22b in the "flow of rotation power supply processing" described later, power supply stop control is performed to turn off the power supply group in the earliest order among the power supply groups targeted for rotation during power supply, and Ib is set. It is also possible to turn off the power supply groups in order until the value drops below, stop the power off operation when the power supply group falls below the level, and continue power supply until the timer predetermined time only for the power supply group during power supply.

In addition, since the total supply current value information is constantly acquired, the current supply end threshold current information, which is the current supply end threshold current value information, which is the threshold value for terminating the current supply, is acquired and held. A value information holding unit may be provided. When the total supply current value information falls below the current supply end threshold current value information while the rotation execution unit (G) controls the group switch unit (C) to supply power to all the power supply groups, the rotation execution unit (G) executes the rotation. The unit (G) can be configured to control the group switch unit (C) to turn off the power supply to all the power supply groups. Alternatively, the timer control means (M) controls the group switch unit (C) to turn off the power supply based on the elapsed time information from the rotation power supply start time, and the power supply is turned off by at least one or more means. You may. It is possible to prevent overcharging of the rechargeable battery of a PC terminal or tablet when it takes a relatively long vacation such as a weekend or a consecutive summer holiday. On the contrary, the timer control means (M) may be configured to start the rotary power supply at the set time lapse or the set date and time. In that case, the rotation power supply system can be started by a timer before the end of a long vacation, and charging can be completed before using it in a class or the like.

<Flow of rotation power supply processing>
22a and 22b show an example of a flowchart based on the sixth embodiment. Even if the service outlet group is based on the seventh embodiment, the same processing is performed. In FIGS. 22a and 22b, the correspondence with each step of FIG. 17 showing the flow of the process of the sixth embodiment is also shown.

This will be described with reference to FIG. 22a. The difference from FIG. 22b is that after the rotation processing is started, the power supply is basically continued and the rotation processing is continued even if the total supply current value information exceeds the power supply stop threshold current value information (Ib). However, as will be described later, this excludes the case where the total supply current value information exceeds Ib when the power supply is turned on only for one power supply outlet or the power supply group. In FIG. 22a, since the power supply is continued even if the total supply current value information exceeds Ib, the power supply may be based on the fifth embodiment, but as described above, the power supply is turned on only to one power supply outlet or the power supply group. Since the judgment using Ib is made so as to exclude the case where the supply current value information exceeds Ib, the sixth embodiment is used as the basis. As in the configuration shown in FIG. 20ab, a cutout is provided so that the maximum rated current does not flow to the external power supply. If the cutout exceeds the maximum rated current even if Ib is exceeded, the cutout is provided. Can be blocked at. Although it is described as "power supply group" in FIGS. 22a and 22b, it can be similarly described by reading it as "power supply outlet for supplying power to the power supply group".

The left side shows the flow of rotation power supply processing. The "startup" process includes the order information holding step (d) (S1701), the new selection stop threshold current value information step (S1702), the power supply stop selection processing threshold current value information holding step (n) (S1703), and the power supply stop. It corresponds to the threshold current value information step (q) (S1704) and the timer information holding step (k) (S1705).

First, "n = 1st ON". If the total current value information exceeds the power supply stop threshold current value information (Ib), an unexpected situation or abnormality is connected to a device that allows a very large current to flow to the power supply outlet or one power supply group. Since there is a possibility that it may occur, the power supply is turned off, an alarm, and a warning light are operated to end the process. If it does not exceed Ib, in the next "I <Ia" part, whether the total supply current value information when power is supplied to the first power supply outlet or power supply group is less than the new selection stop threshold current value information (Ia). Judgment, if true (Y), the process of turning on the power supply outlet or power supply group until the new selection stop threshold current value information (Ia) or more is performed is the total supply current value information acquisition step (b) (S1706). , "Power supply outlet selection, power supply ON", corresponds to the new power supply outlet selection operation determination step (f) (S1707).

Next, in the portion from "timer ON" to "timer OFF", power is supplied to the power supply outlet or the power supply group for which power supply has been turned on for a predetermined time. The process from the timer OFF to the branching of all power supply group power supply is the total supply current value information acquisition step (b) (S1708), rotation execution step (g) (S1710), exception control substep (j) (S1711). ). In the case of the determination branch (Y) of "whether power is being supplied to all power supply groups", the process is returned before the timer is turned on, and the process of restarting power supply to all power supply groups is performed.

Next, from the judgment branch (N) of "whether power is being supplied to all power supply groups" to "I ≤ Ic", the power supply outlets or power supply groups that are being supplied are turned off one by one, and the power supply is stopped. The processing is repeatedly turned off until the value becomes equal to or less than the processing stop threshold current value information (Ic). This process corresponds to the power supply stop processing control sub-step (p) (S1712) and the total supply current value information acquisition step (b) (S1713) in the rotation execution step (g) (S1710).

Next, from "minimum power supply group ON during off" to "I ≤ Ib", new selection stop threshold current value information (Ia) or more, one by one from the power supply outlet that was not power supply or the one with the earliest order of the power supply group. Power is turned on until it becomes. If the new selection stop threshold current value information (Ia) or higher and the power supply stop threshold current value information (Ib) are exceeded, if there is only one power supply outlet or power supply group during power supply, power supply is turned off, and an alarm and warning light are turned on. Turns on and ends the process. This is because there is a possibility that an unexpected device has been connected or an abnormality has occurred. If power is being supplied to multiple power supply outlets or power supply groups, the timer is started again. If the power supply stop threshold current value information (Ib) is exceeded and the rated current value of the rotation supply system is exceeded, it can be cut off if a cutout is provided as shown in Fig. 20 to maintain the safety of the equipment. be able to. The process of this part corresponds to the timer control sub-step (m) (S1714) to the new selection non-execution sub-step (h) (S1717).

Another processing flow will be described with reference to FIG. 22b. In FIG. 22b, two types of flows are operated at the same time. One is the short flow on the right side that is always in operation. The total supply current value information acquisition unit (B) constantly monitors the total supply current value information, and if the value exceeds the power supply stop threshold current value information (Ib), the power supply outlet or power supply group during power supply The power supply is turned off one by one from the earliest order until the value becomes equal to or less than the value of the power supply stop threshold current value information (Ib).

Another flow of FIG. 22b will be described. Since the process from system startup to the branching of determining whether all power supply groups are being supplied after the timer is turned off is the same as in FIG. 22a described above, the description thereof will be omitted. If all power supply outlets or power supply groups are power supply, the process proceeds to the branch of "I ≦ Ib". If “I ≦ Ib”, the pre-processing for turning on the timer is returned, and the processing for resuming power supply to all the power supply outlets or the power supply group is performed. If "I> Ib" (when the power supply stop threshold current value information (Ib) is exceeded) or "whether all power supply groups are supplying power", when the branch is N, the order of the power supply outlet or power supply group during power supply is early. Turn off one by one. When the power supply stop threshold current value information (Ib) or less is reached, the timer is started again. If the power supply stop threshold current value information (Ib) or less is reached and the power supply outlet or power supply group during power supply is 0, the process ends. The process of this part corresponds to the timer control sub-step (m) (S1714) to the new selection non-execution sub-step (h) (S1717).

When determining the processing for the new selection stop threshold current value information (Ia), the power supply stop selection process stop threshold current value information (Ic), and the power supply stop threshold current value information (Ib) in the description of the embodiment. In addition, it does not depend on the gist of the present invention which side of the processing judgment includes the value such as "exceeds", "greater than or equal to", "less than or equal to", and "less than". The same effect can be obtained regardless of which setting is used. In addition, if the maximum rated current value for the device is not exceeded, even if the power supply stop threshold current value information (Ib) is exceeded in the power supply stop control step (r), the rotation power supply may be continued. can. However, since the margin between the maximum rated current value and the maximum rated current value becomes small, it is preferable to configure it so as not to exceed the power supply stop threshold current value information (Ib).

<5. Effect>
By using the rotation power supply system having the above configuration, the number of components is small (that is, at low cost) under the limitation of the capacity of the facility power supply, and the labor for setting is saved, and the order is set. By switching ON / OFF of the power supply to the power supply outlet or the power supply group, charging can be performed in the order close to the optimum.
