  FIG. 4 is a diagram illustrating a hardware configuration of the external terminal 200 of FIG.

  The CPU 201 comprehensively controls each device and controller connected to the system bus 204.

It is remembered. The RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program necessary for execution of processing into the RAM 203 and executing the program.

  An input controller (input C) 205 controls input from a pointing device such as a keyboard 209 or a mouse (not shown). A video controller (VC) 206 controls display on a display device such as a CRT display (CRT) 210. The display device may be a liquid crystal display as well as a CRT. These are used by the administrator as needed. The memory controller (MC) 207 is stored in a hard disk (HD), a floppy (registered trademark) disk, or a PCMCIA card slot that stores a boot program, browser software, various applications, font data, user files, editing files, various data, and the like. Controls access to an external memory 211 such as a compact flash (registered trademark) memory connected via an adapter.

In addition, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the CRT 210.

  A power supply control program for realizing the present invention is recorded in the external memory 211 and is executed by the CPU 201 by being loaded into the RAM 202 as necessary. Furthermore, a definition file and various information tables used by the power supply control program according to the present invention are stored in the external memory 211.

  FIG. 5 is a flowchart showing a control process of the power supply control apparatus 100 according to the present embodiment. This program is stored in the EPROM 104, and is executed by the CPU 103 to execute each step.

  First, the CPU 103 determines whether or not the protection mode is set by SW3 (step S501).

  If the result of determination in step S501 is that the mode is “normal mode”, power is supplied to each CH with a default power supply pattern (step S511). By default, for example, a voltage is applied to the relays 115a to 115d at the same time without delay. In the protection mode, in order to prevent the CH1 to CH4 from being energized at the same time by stopping the voltage applied to the relays 115a to 115d when a current value higher than a predetermined value flows by a protection circuit (not shown), In this mode, the power supply pattern is used, and the normal mode does nothing. The default setting is “protection mode”, and can be switched to “normal mode” using SW3.

  If it is determined in step S501 that the mode is "protection mode", it is determined whether there is a power supply pattern stored in the EPROM 104 (step S502).

  If the result of determination in step S502 is that there is a power supply pattern stored in the EPROM 104, power supply using the power supply pattern stored in the EPROM 104 is started (step S510), and this process is terminated.

  On the other hand, if the result of determination in step S502 is that there is no power supply pattern stored in the EPROM 104, one arbitrary CH is selected, energized (power supplied), and power consumption for a predetermined time (for example, 2 minutes). Data is acquired and stored in the EPROM 104 (step S503). Here, the power consumption data is acquired. However, when the voltage applied to the device is very small, the current consumption data and the power consumption data are in a proportional relationship. Good. In addition, since the predetermined time is a time set for acquiring power consumption data of a device connected to each CH, when the device connected to each CH is turned on, activated, and in an energy saving mode. Time required for detecting the power consumed in the time and standby mode is preferable.

  Next, feature extraction of the power consumption pattern is performed from the power consumption data stored in the EPROM 104 (step S504). Here, for example, power consumption data as shown in FIG. 6A is averaged conditionally. When averaging, data having a difference in amperage greater than or equal to a predetermined value is not averaged, and data within a predetermined value is averaged in a relatively fine unit (for example, 0.1 second). By repeating this process a predetermined number of times while slightly changing the difference in the amperage, a power consumption pattern as shown in FIG. 6B is acquired.

  Next, the CPU 103 extracts a characteristic relationship between the power consumption value and time from the power consumption pattern of FIG. 6B and stores it in the EPROM 104 (step S505). Here, the averaged values having the same amperage are extracted together with the time information, and a table as shown in FIG. 7 is created and stored in the EPROM 104.

  Subsequently, for all outlets (CH1 to CH4), it is determined whether or not the creation of the table of FIG. 7 has been completed (step S506). If the creation of the table of FIG. 7 has not been completed, step S503 is performed. On the other hand, when the creation of the table of FIG. 7 is completed, a power supply pattern is created using the result (step S507). For example, when starting a device whose maximum allowable current value of the power supply control device 100 is 18 A and inrush current as shown in FIG. 7 is activated, when other devices are already operating, the total current value is There is a possibility of exceeding 18A. For this reason, the power supply to the outlet to which the device shown in FIG. 7 is connected is first performed, and after stabilization (for example, after 30 seconds), to the outlet (CH) to which another device is connected. In order to supply power, a power supply pattern such as voltage supply to a relay corresponding to the CH is created.

  Next, it is determined whether or not power can be supplied to all devices connected to the respective outlets (CH1 to CH4) (step S508). If there is a device that cannot supply power, a warning is issued. (Step S512). As a warning method, the LED provided on the display unit 111 or the numerical value display unit 301 may be blinked, a beep sound is output from a sound output unit (not shown), or “the maximum current value is exceeded”. Such audio data may be output. In the determination in step S508, the combination of the maximum allowable current value and the inrush current of each device and the current during normal operation is compared as described above to determine whether the maximum allowable current is exceeded in any way. It is.

  On the other hand, if it is determined in step S508 that power can be supplied to all devices, the power supply pattern created in step S507 is stored in the EPROM 104 (step S509), and the stored power supply pattern is stored. Based on the above, power supply to all devices connected to the respective outlets (CH1 to CH4) is started (step S510), and this process is terminated.

  In the control processing of the power supply control device 100 described above, the power supply control device 100 creates a power supply pattern by itself and executes power supply to all devices connected to each outlet (CH1 to CH4). However, the external terminal 200 connected to the power supply control apparatus 100 via the network 700 creates a power supply pattern for the power supply control apparatus 100 and transmits the power supply pattern to the power supply control apparatus 100, so that the power supply control apparatus 100 You may make it perform the power supply to all the apparatuses connected to each outlet (CH1-CH4) based on this power supply pattern. As a result, the external terminal 200 can execute remote control of the power supply control device 100.

  Hereinafter, a case where the external terminal 200 executes remote control of the power supply control device 100 will be described.

  FIG. 8 is a flowchart showing a process for displaying power consumption data of the power supply control device 100 on the CRT 210. This process is executed by the CPU 201 of the external terminal 200.

  First, it is determined whether or not power consumption data for a predetermined time (for example, 2 minutes) for each CH has been received (step S201). The power consumption data for a predetermined time for each CH is transmitted to the external terminal 200 via the NIC 107, and the external terminal 200 receives the power consumption data via the communication I / FC 208. The determination in step S201 is repeated until power consumption data for all CHs is received. After receiving the power consumption data of all the CHs, the power consumption data of all the CHs is stored in the RAM 203 or the external memory 211 (step S802), and the power consumption data is displayed on the CRT 210 via the video controller 206. (Step S803), the process is terminated. FIG. 9 is a diagram showing the power consumption data of CH1 displayed on the CRT 210 of the external terminal 200.

  FIG. 10 is a flowchart illustrating processing in which the external terminal 200 executes remote control of the power supply control device 100. The CPU 201 of the external terminal 200 loads the program stored in the external memory 211 into the RAM 203 and executes it, thereby performing the necessary processing in the external terminal 200 below.

  First, the CPU 103 of the power supply control device 100 determines whether or not the protection mode is set by SW3 (step S1001).

  If the result of determination in step S1001 is that the mode is “normal mode”, power is supplied to each CH using the default power supply pattern (step S1009), and this process ends. On the other hand, if the result of determination in step S501 is that the mode is “protection mode”, it is determined whether or not there is a power supply pattern stored in the EPROM 104 (step S1002). If there is a power supply pattern stored in the EPROM 104, power supply by the power supply pattern stored in the EPROM 104 is started (step S1008), and this process is terminated. On the other hand, if there is no power supply pattern stored in the EPROM 104, the CPU 103 transmits a power supply pattern generation request to the external terminal 200 (step S1003), selects one arbitrary CH, and supplies power (power supply). Supply), power consumption data for a predetermined time (for example, 2 minutes) is acquired, and the acquired power consumption data is transmitted to the external terminal 200 together with the CH information (step S1004). Thereafter, it is determined whether or not CH information and power consumption data have been transmitted to the external terminal 200 for all outlets (CH1 to CH4) (step S1005), and CH information and consumption for all outlets (CH1 to CH4). If the transmission of power data has not ended, the process of step S1004 is repeated. On the other hand, if the transmission of CH information and power consumption data has ended for all outlets (CH1 to CH4), the external terminal 200 It is determined whether or not a power supply pattern for each CH has been received (step S1006).

  If the power supply pattern for each CH is not received from the external terminal 200, the determination process in step S1106 is repeated. On the other hand, if the power supply pattern for each CH is received from the external terminal 200, the received power supply pattern is received. Is stored in the EPROM 104 (step S1007), and power supply to all the devices connected to the respective outlets (CH1 to CH4) is started based on the stored power supply pattern (step S1008). finish.

  On the other hand, the CPU 201 of the external terminal 200 determines whether or not a power supply pattern generation request has been received from the power supply control apparatus 100 (step S1010), and receives a power supply pattern generation request from the power supply control apparatus 100. Until the power supply pattern generation request is received, the CH information and the power consumption data for each CH transmitted from the power supply control device 100 are received in step S1004, and the RAM 203 or Save in the external memory 211 (step S1011).

  The CPU 201 performs feature extraction of the power consumption pattern from the power consumption data for each CH stored in the RAM 203 or the external memory 211 (step S1012). Here, the power consumption data averaging process as described in step S504 is executed. Next, a characteristic relationship between the power consumption value and the time is extracted from the power consumption pattern and stored in the RAM 203 or the external memory 211 (step S1013). Here, the averaged values having the same amperage are extracted together with the time information, a table as shown in FIG. 7 is created, and stored in the RAM 203 or the external memory 211.

  Subsequently, for all outlets (CH1 to CH4), it is determined whether or not the creation of the table of FIG. 7 has been completed (step S1014). If the creation of the table of FIG. On the other hand, when the creation of the table of FIG. 7 is completed, a power supply pattern is created using the result and stored in the RAM 203 or the external memory 211 (step S1015). Although omitted for the sake of simplicity, in step S1015, the external terminal 200 may perform the determination in step S508 described above and perform the warning process in step S512.

  Thereafter, the power supply pattern for each CH stored in the RAM 203 or the external memory 211 is transmitted to the power supply control apparatus 100 (step S1006), and this process is terminated.

  As described above, according to the present embodiment, the power supply control device 100 extracts the characteristics of the power consumption pattern of each CH alone, and the relationship between the power consumption value and the time from the characteristics of the power consumption pattern. And a power supply pattern is created based on this relationship, and power is supplied to each CH based on the power supply pattern. Therefore, when devices connected to a plurality of CHs are simultaneously activated, The power supply can be prevented from dropping, and a plurality of devices can be started up efficiently.

  In addition, when a switch for supplying power to the power supply control device at a time is provided and the switch is turned on, or when the outlet of the power supply control device is connected to a commercial power supply with multiple devices connected In addition, even if a device with a large inrush current is included and the power is normally turned off, the power can be supplied. Further, by generating the power supply pattern, it is not necessary for a human to judge and generate the power supply pattern, and it is possible to avoid troublesome work. In addition, an inaccurate power supply pattern can be prevented.

  Further, in the power supply control system in which the external terminal 200 and the power supply control apparatus 100 are connected via the network 700, the external terminal 200 extracts the characteristics of the power consumption pattern of each CH, and the characteristics of this power consumption pattern. The relationship between the power consumption value and time is extracted from this, and a power supply pattern is created based on this relationship and transmitted to the power supply control device 100. Each of the power supply control devices 100 is based on the power supply pattern. Since power is supplied to the CH, it is possible to prevent the power from being dropped when devices connected to each of the plurality of CHs are simultaneously activated, and to efficiently start up the plurality of devices. be able to. In addition, the external terminal 200 can control energization and power consumption of each CH of the power supply control device 100.

  In the flowchart of FIG. 10, after the process of step S1006, it is not determined whether power can be supplied to all devices connected to each of the CH1 to CH4. However, this determination process is performed. May be. If there is a device that cannot supply power, the power supply control device 100 may issue a warning, or information on the presence of a device that cannot supply power is transmitted to the external terminal 200, and the information is sent to the CRT 210. You may make it display.

  The external terminal 200 can be connected to a plurality of power supply control devices, for example, connected to two power supply control devices, and the two power supply control devices have a total of 8 CHs. Alternatively, the power supply pattern can be generated so that the eight CHs do not exceed the maximum allowable power (current) value.
