Description

The present invention relates to an evaluation device for evaluating a power supply device.

  Various AC adapters (a type of power supply device) exist due to diversification of electronic devices, and other AC adapters may be inadvertently connected inadvertently. Here, AC is an abbreviation for altering current.

  If the AC adapter is connected incorrectly, the connected electrical device may be damaged, and if it is severe, it may lead to a burnout accident. The reason is that if the current capacity of the AC adapter is too large, the electrical device may cause an excessive current to flow through the electrical device due to incorrect connection, and heat may be generated due to the excess current. On the other hand, when the current capacity of the AC adapter is too small, malfunction may occur in the electrical device due to incorrect connection.

  The following method is disclosed in order to prevent erroneous connection of the AC adapter. For example, Patent Documents 1 and 2 disclose a method for protecting a circuit by monitoring an input voltage from an AC adapter. Patent Document 3 discloses a method of protecting a circuit by monitoring a noise level from an AC adapter.

  On the other hand, in Patent Document 4, a predetermined voltage level is generated while the power supply pressure is lower than the reference voltage level, and the predetermined voltage is exceeded when a time until the power supply pressure decreases below the normal operating voltage is exceeded. A method for generating the display signal in response to a level is disclosed.

  However, since there are many AC adapters having the same rated voltage and different current capacities, there is a possibility that the AC adapter determined to be appropriate by the method of monitoring the input voltage from the AC adapter is not necessarily appropriate. is there.

  Also, there is no problem with the power supply noise for a while after connection, and the AC adapter may generate abnormal heat after a long period of use. Therefore, the AC adapter determined to be appropriate by the method of monitoring power supply noise described above is not necessarily appropriate. It may not be.

The evaluation unit derives a predetermined evaluation result regarding the voltage value drop state due to disconnection of the supply device from the power supply after the supply device is connected to the power supply. The output unit outputs the evaluation result.

<First embodiment>
The first embodiment is an embodiment related to an electrical device that determines whether or not the supply device is suitable for supplying power to the electrical device based on the time required for the voltage drop of the input from the supply device.
[Configuration and operation]
FIG. 1 is a conceptual diagram illustrating a configuration of a power supply system 100a that is an example of a power supply system to which the electrical device of the first embodiment can be applied.

  The power supply system 100a includes a supply device 101a and an electric device 136a.

  The supply device 101a is a device for converting electric power supplied from a power source (not shown) into predetermined DC power and supplying the converted electric power to a certain electric device (not limited to the electric device 136a). . The supply device 101a is an AC adapter that converts AC power supplied typically through an outlet and supplies it to an electrical device.

  The supply apparatus 101a includes a conversion unit 156a. The conversion unit 156a supplies the power obtained by converting the power supplied from the power source to the connection unit 146 of the electric device 136a.

  The electrical device 136a includes a connection unit 146, a control unit 141a, and an operation unit 131a.

  The connection unit 146 is a part that connects or disconnects the output from the supply device 101a to the inside of the electric device 136a by an external operation such as a person. The connection part 146 is typically a connector.

  The control unit 141a is a part that determines whether or not the supply device 101a is suitable as a supply device that supplies power to the electrical device 136a, and performs processing described later according to the determination result. In the following, the determination as to whether or not the supply device 101a is suitable as a supply device that supplies power to the electrical device 136a is “appropriate determination”, and the evaluation of the supply device 101a based on the appropriate determination is “appropriate evaluation”. I will say.

  The control unit 141a includes a voltage measurement unit 127a, a processing unit 121a, a display unit 126a, a connection unit 111a, and a sub power source 116a.

  In addition, the wiring represented by the solid line in the power supply system 100a is a path of supplied power that connects the components illustrated in FIG. Moreover, the wiring represented by the dotted line in the power supply system 100a is a signal path that connects the processing unit 121a and each component connected to the processing unit 121a.

  The voltage measurement unit 127 a is a voltmeter that sequentially measures the voltage input from the connection unit 146. And the voltage value which concerns on the said voltage is sent to the process part 121a sequentially.

  The processing unit 121a determines from the voltage value sent from the voltage measurement unit 127a whether or not the supply device 101a is once disconnected from the power source after being connected to the power source. A specific example of this determination will be described later in the [Processing flow] section. The connection and disconnection of the supply device 101a from the power source can be performed by human work such as inserting a plug into an outlet or removing a plug from the outlet.

  When it is determined that the cutting has been performed, the processing unit 121a starts measuring elapsed time using a timer (not shown) based on the determination time.

  Then, the processing unit 121a determines whether or not the voltage value sent from the voltage measurement unit 127a is smaller than a predetermined threshold Th3.

  When determining that the voltage value has fallen below the threshold Th3, the processing unit 121a records the elapsed time at the time of the determination in a recording unit (not shown).

  Then, the processing unit 121a determines whether or not the elapsed time is in a range for a predetermined elapsed time.

  When the processing unit 121a determines that the elapsed time is in the range, the processing unit 121a transmits instruction information for instructing a display indicating that the supply device 101a is appropriate to supply power to the electric device 136a. The processing unit 121a also sends information instructing connection between the terminals A and B to the connection unit 111a.

  On the other hand, if the processing unit 121a does not determine that the elapsed time is in the range, the processing unit 121a displays instruction information indicating a display indicating that the supply device 101a is not appropriate for supplying power to the electrical device 136a. send. Then, when the terminals A and B are connected, the processing unit 121a sends instruction information for instructing disconnection between the terminals A and B to the connection unit 111a. When the space between the terminals A and B has already been disconnected, the processing unit 121a maintains the disconnection.

  The display unit 126a displays the instructed content according to the instruction information from the processing unit 121a. The display unit 126a is, for example, a display.

  The connection unit 111a is a switch that performs connection and disconnection between the terminals A and B in accordance with information transmitted from the processing unit 121a.

  The sub power supply 116a supplies necessary power for a predetermined period when the supply apparatus 101a is disconnected from the power supply after the supply apparatus 101a is connected to the power supply, and the input voltage is thereby reduced. Do. The power supply targets are the voltage measurement unit 127a, the processing unit 121a, the display unit 126a, and the connection unit 111a. The input voltage is a voltage input through the connection unit 146.

  When predetermined power is supplied from the connection unit 146, the operation unit 131a performs a predetermined operation using the power. The predetermined operation is a main operation performed by the electric device 136a. For example, when the electric device 136a is a mobile phone, the predetermined operation is a communication operation associated with a call or the like.

  FIG. 2 is a conceptual diagram illustrating a configuration of a processing unit 121b that is an example of the processing unit 121a illustrated in FIG.

  The processing unit 121b includes a calculation unit 164a, a recording unit 162a, and a timer 163a. The terminals a, b, and c are connected to the voltage measurement unit 127a, the connection unit 111a, and the display unit 126a shown in FIG. 1 through signal lines, respectively.

  The calculation unit 164a performs a calculation for processing performed by the processing unit 121b. The calculation unit 164a includes, for example, a central processing unit.

  The recording unit 162a records information instructed by the calculation unit 164a. The recording unit 162a also sends information held by an instruction from the calculation unit 164a to the calculation unit 164a.

  The timer 163a measures the elapsed time according to an instruction from the calculation unit 164a. Then, the timer 163a sends the measured time to the sequential calculation unit 164a.

  Each component of the processing unit 121b is operated by electric power sent to the terminal D. In FIG. 2, the wiring between the terminal D and each component is not shown.

  FIG. 3 is a conceptual diagram illustrating a configuration of a sub power source 116b that is an example of the sub power source 116a illustrated in FIG.

  The sub power supply 116b includes a diode 137a and a capacitor 138a.

  The capacity of the capacitor 138a is determined based on the evaluation process performed by the processing unit 121a, the process performed by the evaluation result, and the current and voltage necessary for the operations performed by the voltage measurement unit 127a, the display unit 126a, and the connection unit 111a. And the operation time. Here, the evaluation is an evaluation as to whether or not the supply device 101a is an appropriate supply device that should supply power to the electrical device 136a.

  The left end of the diode 137a is connected to the terminal E. The right end of the diode 137a is connected to the upper end of the capacitor 138a and the terminal F. The lower end of the capacitor 138a is connected to the ground 139a. In the description of the embodiment, the upper, lower, left, and right represent the upper, lower, left, and right in the drawing to be described unless otherwise specified.

  As described above, power (voltage) is supplied to the left end of the diode 137a through the terminal E from the supply device 101a shown in FIG. The voltage passes through the diode 137a and is supplied to the upper end of the capacitor 138a. The capacitor 138a is charged by the supply. As described above, even after the supply device 101a is disconnected from the power source and the power supplied from the supply device 101a to the electrical device 136a through the connection unit 146 decreases, the capacitor 138a is Continue supplying. What is supplied with electric power is a connection unit 111a, a voltage measurement unit 127a, a processing unit 121a, and a display unit 126a.

  The diode 137a cuts off the current from the right side to the left side of the diode 137a. Accordingly, power is not supplied from the capacitor 138a to the operation unit 131a through the connection unit 111a.

The sub power supply 116a shown in FIG. 1 may be a simple battery other than the sub power supply 116a shown in FIG. In that case, the terminal E can be deleted.
[Processing flow]
FIG. 4 is a conceptual diagram illustrating an example of a processing flow of an evaluation process performed by the processing unit 121a illustrated in FIG. The evaluation is an evaluation as to whether or not the supply device 101a is an appropriate supply device that should supply power to the electrical device 136a.

  The processing unit 121a first determines whether or not the voltage value sent from the voltage measurement unit 127a exceeds the threshold Th1 as the processing of S101. Here, the threshold value Th1 is a threshold value for the voltage value determined in advance for the process of S101. The process of S101 is a process performed to determine whether or not the supply apparatus 101a illustrated in FIG. 1 is connected to the connection unit 146 and the supply apparatus 101a is connected to a power source.

  The processing unit 121a performs the process of S103 when the determination result by the process of S101 is yes.

  On the other hand, the process part 121a performs the process of S101 again, when the determination result by the process of S101 is no.

  When performing the process of S103, the processing unit 121a determines whether the supply apparatus 101a is disconnected from the power source as the same process. As described above, the cutting can be performed by an external person such as a person. For example, the processing unit 121a performs the determination by determining that the amount of decrease in the voltage value within a unit time exceeds a predetermined value.

  The processing unit 121a performs the process of S104 when the determination result by the process of S103 is yes.

  On the other hand, when the determination result of the process of S103 is no, the processing unit 121a performs the process of S103 again.

  When performing the process of S104, the processing unit 121a starts measuring elapsed time as the same process.

  And the process part 121a determines whether the said voltage value fell below threshold value Th3 as a process of S105. Here, the threshold Th3 is a threshold for the voltage value determined in advance for the process of S105. The threshold value Th3 is determined, for example, by selecting an appropriate value from the change over time of the voltage value when using a supply device that is known to be suitable for supplying electric power to the electrical device 136a.

  The process part 121a performs the process of S106, when the determination result by the process of S105 is yes.

  On the other hand, when the determination result obtained in S105 is no, the processing unit 121a performs the process in S105 again.

  When performing the process of S106, the processing unit 121a records the elapsed time as the same process.

  And the process part 121a determines whether the said elapsed time is in a predetermined range as a process of S107. The predetermined range is a range for an elapsed time predetermined for the process of S107.

  The processing unit 121a performs the process of S108 when the determination result by the process of S107 is yes.

  On the other hand, the process part 121a performs the process of S109, when the determination result by the process of S107 is no.

  When performing the process of S108, the processing unit 121a records that the evaluation result is OK. Here, the evaluation result of “OK” is an evaluation result indicating that the supply device 101a is appropriate as a device that supplies power to the electric device 136a.

  Further, when performing the process of S109, the processing unit 121a records that the evaluation result is NG. Here, the evaluation result of “NG” is an evaluation result indicating that the supply apparatus 101a is inappropriate for supplying power to the electric device 136a. A process performed by the processing unit 121a on the connection unit 111a and the display unit 126a based on the evaluation result when the evaluation result is OK or NG will be described later with reference to FIG.

  Then, the processing unit 121a ends the process illustrated in FIG.

  FIG. 5 is a conceptual diagram illustrating an example of a processing flow of processing performed by the processing unit 121a based on an evaluation result by the processing illustrated in FIG.

  As a premise of the process illustrated in FIG. 5, the supply device 101 a illustrated in FIG. 1 is connected to the connection unit 146, and the supply device 101 a is further connected to a power source.

  First, the processing unit 121a sends connection instruction information to the connection unit 111a as processing of S200A. The connection unit 111a receives the connection instruction information and connects the terminals A and B. As a result, power is supplied from the supply device 101a to the operating unit 131a.

  Next, the processing unit 121a starts measuring time as the processing of S200B, and then determines whether a predetermined time has elapsed. The process of S200B is performed in order to wait for a certain period of time estimated to end the process shown in FIG. 4 started by supplying power from the supply device 101a started by the process of S200A to the operation unit. It is processing.

  The process part 121a performs the process of S201, when the determination result by the process of S200B is yes.

  On the other hand, the process part 121a performs the process of S200B again, when the determination result by the process of S200B is no.

  When performing the process of S201, the processing unit 121a transmits, to the connection unit 111a, instruction information for disconnecting the terminals A and B illustrated in FIG. The connection unit 111a receives the instruction information and disconnects the terminals A and B.

  Next, the processing unit 121a reads the evaluation result as the processing of S202. The evaluation result is recorded by the processing unit 121a by the processing of S108 or S109 shown in FIG.

  And the process part 121a determines whether the evaluation result read by the process of S202 is OK as a process of S203. At this time, if the evaluation result is NG or there is no evaluation result yet, it is determined that the evaluation result is not OK.

  If the determination result obtained in step S203 is yes, the processing unit 121a performs step S203A.

  On the other hand, the process part 121a performs the process of S203B, when the determination result by the process of S203 is no.

  When performing the processing of S203A, the processing unit 121a sends instruction information for instructing the display unit 126a to display that the evaluation result is OK. In response to the instruction information, the display unit 126a displays that the evaluation result is OK. The display is, for example, a character display of “Good connection” or continuous lighting of a green lamp. The display unit 126a may express that the evaluation result is OK by voice or vibration together with the display or instead of the display.

  And the process part 121a sends the instruction information showing the instruction | indication to connect between terminal AB shown in FIG. 1 with respect to the connection part 111a as a process of S204.

  Then, the processing unit 121a performs the process of S205.

  On the other hand, when performing the process of S203B, the processing unit 121a sends instruction information for instructing the display unit 126a to display that the evaluation result is NG. Upon receiving the instruction information, the display unit 126a displays that the evaluation result is NG. The display is, for example, a character display “connection failure”, blinking of a red lamp, or the like. The display unit 126a may express that the evaluation result is NG by voice or vibration together with the display or instead of the display.

  Then, the processing unit 121a performs the process of S205.

  When performing the process of S205, the processing unit 121a determines whether to end the process illustrated in FIG. 5 as the same process. The processing unit 121a performs the determination by, for example, determining whether there is input of end information from the outside.

  When the determination result in S205 is yes, the processing unit 121a ends the process illustrated in FIG.

  On the other hand, when the determination result in S205 is no, the processing unit 121a performs the process in S202 again.

  When the supply device 101a shown in FIG. 1 is suitable for supplying power to the electric device 136a, the electrical device 136a shown in FIG. 1 obtains an evaluation result indicating that it is OK by the process of S108 in FIG. Then, the electrical device 136a displays the evaluation result indicating that it is OK by the processing of S203A shown in FIG. 5 based on the evaluation result indicating that it is OK. Further, the electric device 136a can supply the power from the supply device 101a to the operation unit 131a by the process of S204 based on the evaluation result indicating that the device is OK. Therefore, when the supply device 101a is connected to the power supply in this state, power is supplied from the supply device 101a to the operation unit 131a.

  On the other hand, if the supply device 101a shown in FIG. 1 is inappropriate for supplying electric power to the electric device 136a, the electric device 136a obtains an evaluation result indicating that it is NG by the process of S109 of FIG. Then, the electrical device 136a displays the evaluation result indicating NG by the processing of S203B illustrated in FIG. 5 based on the evaluation result indicating that the device is NG. Further, the electric device 136a holds a state where the electric power from the supply device 101a is not supplied to the operation unit 131a by the process of S201 based on the evaluation result indicating that the electric device 136 is NG. Therefore, when the supply device 101a is connected to the power supply in this state, power is not supplied from the supply device 101a to the operation unit 131a.

In this way, it is possible to suppress damage to the operation unit 131a that occurs when the control unit 141a and the supply device 101a are not suitable for supplying electric power to the electric device 136a.
[effect]
When the supply device 101a is connected to the power source and then disconnected from the power source in a state where the supply device 101a is connected to the connection unit 146, the control unit 141a illustrated in FIG. The evaluation result relating to the appropriate evaluation is obtained. The control unit 141a obtains the evaluation result from the time required for a predetermined drop in the voltage value related to the input from the supply device 101a when the supply device 101a is connected to the power supply and then disconnected from the power supply.

  The voltage drop state related to the input from the supply device 101a is determined by the output impedance of the supply device 101a and the current load of the electric device 136a. Here, the drop state is a voltage drop state with respect to an input from the connection unit 146 when the supply device 101a is disconnected from the power supply after power is supplied from the supply device 101a to the operation unit 131a of the electric device 136a. is there. Therefore, if the lowering state of the supply device 101a approximates the lowering state of the supply device designed for the electric device 136a, the supply device is suitable for supplying electric power to the electric device. Can be determined.

  The time required for the above-mentioned descent is a value representing the descent state. Therefore, if the time required for the descent is close to the time required for the descent of the supply device designed for the electric device 136a, the supply device 101a is appropriate as a device for supplying power to the electric device 136a. Can be determined.

  The control unit 141a presents the evaluation result to a user or the like, and performs a treatment to enable or disable power supply to the operation unit 131a based on the evaluation result. As described in the section “Background Art”, if the current capacity of the supply device is too large, the electrical device may cause an excessive current to flow through the electrical device due to incorrect connection, and heat may be generated due to the excess current. is there.

The control unit 141a disables power supply to the operation unit 131a when the supply device 101a is not suitable for supplying power to the electrical device 136a, and therefore, the control unit 141a supplies power to the operation unit 131a that may be caused by excessive current. Damage can be suppressed.

That is, the processing unit 121a illustrated in FIG. 6 sends instruction information for instructing connection and disconnection between the terminals GH by the connection unit 151a to the supply device 101a.

In what case the processing unit 121a shown in FIG. 6 sends the instruction information will be described later in the section of the processing flow.
[Processing flow]
The processing flow example of the evaluation processing performed by the processing unit 121a illustrated in FIG. 6 is obtained by replacing the processing of S101 and S103 illustrated in FIG. 4 with the processing illustrated in FIG.

  FIG. 7 is a conceptual diagram showing processing for replacing the processing of S101 and S103 shown in FIG.

  The processing unit 121a illustrated in FIG. 6 sends connection instruction information to the connection unit 151a of the supply apparatus 101a as the process of S102-2 after the start illustrated in FIG. Receiving the connection instruction information, the connection unit 151a performs connection between the terminals GH.

  And the process part 121a starts measurement of time as a process of S102-3, and determines whether predetermined time passed after that. In the process of S102-3, the connection between the terminals GH by the connection unit 151a is performed based on the connection instruction information sent in the process of S102-2, and the power from the supply device 101a to the operation unit 131a of the electric device 136a This is a process performed to wait for the supply to be performed.

  When the determination result of the process of S102-3 is yes, the processing unit 121a performs the process of S102-4.

  On the other hand, when the determination result of the process of S102-3 is no, the processing unit 121a performs the process of S102-3 again.

  When performing the processing of S102-4, the processing unit 121a sends the disconnection instruction information to the connection unit 151a as the same processing.

In what case the processing unit 121a shown in FIG. 9 sends the instruction information will be described later in the section of the processing flow.
[Processing flow]
The processing flow example of the evaluation processing performed by the processing unit 121a illustrated in FIG. 9 is obtained by replacing the processing of S101 and S103 illustrated in FIG. 4 with the processing illustrated in FIG.

  FIG. 10 is a conceptual diagram showing processing for replacing the processing of S101 and S103 shown in FIG.

  The processing unit 121a illustrated in FIG. 9 instructs the communication unit 124a to send connection instruction information to the communication unit 125a as a process of S102-2a after the start illustrated in FIG. Receiving the instruction, the communication unit 124a sends connection instruction information to the communication unit 125a. The connection instruction information is sent from the communication unit 125a to the connection unit 151a. And the connection part 151a performs the connection between terminal GH.

  Next, the processing unit 121a starts measuring time as the processing of S102-3, and determines whether or not a predetermined time has elapsed thereafter. In the process of S102-3, the connection between the terminals GH by the connection unit 151a is performed based on the connection instruction information sent in the process of S102-2, and the power from the supply device 101a to the operation unit 131a of the electric device 136a This is a process performed to wait for the supply to be performed.

The power supply system 100a illustrated in FIG. 6 requires a wired signal path for sending instruction information from the processing unit 121a to the connection unit 151a. On the other hand, the power supply system 100a illustrated in FIG. 9 wirelessly transmits and receives information between the supply device 101a and the electric device 136a.

<Fourth embodiment>
The fourth embodiment is an embodiment of an electric device that performs appropriateness determination in consideration of a noise level related to an input from the supply device to the electric device.
[Configuration and operation]
FIG. 12 is a conceptual diagram illustrating a configuration of a power supply system 100a that is an example of a power supply system to which the electric device of the fourth embodiment can be applied.

  The description of the power supply system 100a illustrated in FIG. 12 is the same as the description of the power supply system 100a illustrated in FIG. 1 except for the following. However, when the following description and the description of FIG. 1 conflict, the following description is given priority.

  The control unit 141a of the supply device 101a illustrated in FIG. 12 includes a signal path represented by a dotted line between the noise measurement unit 128a and the processing unit 121a and the noise measurement unit 128a in addition to the configuration included in the control unit 141a illustrated in FIG. With.

  The noise measurement unit 128a observes the noise level at the input from the connection unit 146. The noise level is, for example, a voltage value of a voltage component having a frequency equal to or higher than a predetermined frequency at the input. The noise measuring unit 128a is, for example, a noise measuring device that can measure an alternating voltage having a noise level.

  The noise measuring unit 128a sends the measured noise level to the processing unit 121a.

  The terminal J of the noise measuring unit 128a is connected to the sub power supply 116a. When the voltage level of the input from the connection unit 146 is reduced due to the supply device 101a being disconnected from the power source, the noise measurement unit 128a is required to operate from the sub power source 116a to the noise measurement unit 128a. Power is supplied.

  The processing unit 121a derives an evaluation result related to appropriate evaluation based on the voltage value sent from the voltage measuring unit 127a and the noise level sent from the noise measuring unit 128a. An example of a derivation method by which the processing unit 121a derives the evaluation result will be described later in the section of the processing flow.

The processing unit 121a performs processing performed based on the evaluation result. A specific example of the control will be described later in the section of the processing flow.
[Processing flow]
The first example of the processing flow of the evaluation processing performed by the processing unit 121a illustrated in FIG. 12 is the processing of S107-1 and S107-2 illustrated in FIG. 13 between the yes of S107 illustrated in FIG. 4 and the processing of S108 and S109. A process is inserted.

  FIG. 13 is a conceptual diagram illustrating processing to be inserted into the evaluation processing illustrated in FIG. 4 performed by the processing unit 121a illustrated in FIG.

  The processing unit 121a illustrated in FIG. 12 records the noise level transmitted from the noise measurement unit 128a as the processing of S107-2 after the yes of S107 illustrated in FIG.

  And the process part 121a determines whether the noise level recorded by the process of S107-1 is larger than threshold value Th5 as a process of S107-2. Here, the threshold Th5 is a threshold for the noise level sent from the noise measuring unit 128a, which is predetermined for the process of S107-2.

  If the determination result obtained in S107-2 is yes, the processing unit 121a performs the process in S109 illustrated in FIG.

  On the other hand, when the determination result obtained in S107-2 is no, the processing unit 121a performs the process of S108 illustrated in FIG.

  When performing the evaluation process, the processing unit 121a illustrated in FIG. 12 adds the noise level of the input from the supply apparatus 101a to the information used for the evaluation process. As disclosed in Patent Document 3, when the supply device is not suitable for supplying electric power to an electric device, noise may increase in the supplied electric power. The processing unit 121a illustrated in FIG. 12 can derive a more accurate evaluation result by adding the noise level to the information used for the evaluation process.

  In the above, the supply apparatus 101a demonstrated the case where the evaluation result which concerns on appropriate evaluation was a two step. However, as will be described below, the evaluation result may have three or more stages. And the process part 121a may perform the process performed by the evaluation result based on the said 3 or more step evaluation result so that it may demonstrate below.

  In the second processing flow example of the evaluation processing performed by the processing unit 121a shown in FIG. 12, the processing shown in FIG. 14 is inserted into the processing flow shown in FIG. 4, and the processing of S108 and S109 shown in FIG. It is replaced with the process shown in.

  FIG. 14 is a conceptual diagram showing processing to be inserted into the processing flow shown in FIG.

  The processing unit 121a records level 2 in the evaluation result as processing of S102 after yes of S107 illustrated in FIG. The level 2 evaluation result is intermediate between the three levels of evaluation results. The processing performed by the processing unit 121a in the case of level 2 will be described later with reference to FIG.

  The processing unit 121a performs the process of S103 illustrated in FIG. 4 after S102.

  FIG. 15 is a conceptual diagram showing processing for replacing the processing of S108 and S109 shown in FIG.

  The processing unit 121a records the noise level sent from the noise measuring unit 128a as the processing of S107-1 after yes of S107 shown in FIG.

  And the process part 121a determines whether the noise level recorded by the process of S107-1 is higher than threshold value Th6 as a process of S111. Here, the threshold Th6 is a threshold for the noise level sent from the noise measuring unit 128a, which is predetermined for the processing of S111.

  The processing unit 121a performs the process of S112 when the determination result by the process of S111 is yes, or when the determination result by the process of S107 illustrated in FIG. 4 is no.

  On the other hand, the process part 121a performs the process of S113, when the determination result by the process of S111 is no.

  When performing the process of S112, the processing unit 121a rewrites the evaluation result to level 3 as the same process. Level 3 is an evaluation result indicating that the supply apparatus 101a is most inappropriate among the three-stage evaluation results for supplying power to the operating unit. The processing performed by the processing unit 121a in the case of level 3 will be described later with reference to FIG.

  And the process part 121a complete | finishes the process represented to FIG.4, FIG14 and FIG.15.

  When performing the process of S112, the processing unit 121a determines whether or not the noise level sent from the noise measurement unit 128a is higher than the threshold value Th7. Here, the threshold value Th7 is a threshold value for the noise level sent from the noise measuring unit 128a, which is predetermined for the processing of S111. The threshold value Th7 is a value lower than the aforementioned threshold value Th6.

  If the determination result obtained in step S113 is yes, the processing unit 121a ends the processes illustrated in FIGS. Thereby, the processing unit 121a maintains the level 2 evaluation result recorded by the processing of S102 shown in FIG.

  On the other hand, the process part 121a performs the process of S114, when the determination result by the process of S113 is no.

  When performing the process of S114, the processing unit 121a rewrites the evaluation result to level 1 as the same process. The evaluation result of level 1 is an evaluation result indicating that the supply device 101a is most suitable as the supply device 101a for supplying power to the operation unit among the three-stage evaluation results. Processing performed by the processing unit 121a when the evaluation result is level 1 will be described later with reference to FIG.

  And the process part 121a complete | finishes the process represented to FIG.4, FIG14 and FIG.15.

  In this way, the processing unit 121a illustrated in FIG. 12 holds the evaluation result of any one of the levels 1 to 3 by the processing illustrated in FIGS.

  FIG. 16 is a conceptual diagram illustrating an example of a processing flow of processing performed based on an evaluation result performed by the processing unit 121a illustrated in FIG.

  As a premise of the process illustrated in FIG. 16, the supply device 101a illustrated in FIG. 12 is connected to the connection unit 146, and the supply device 101a is connected to a power source.

  First, the processing unit 121a sends connection instruction information to the connection unit 111a as processing of S200A. The connection unit 111a receives the connection instruction information and connects the terminals A and B. As a result, power is supplied from the supply device 101a to the operating unit 131a.

  Next, the processing unit 121a starts measuring time as the processing of S200B, and then determines whether a predetermined time has elapsed. The process of S200B is performed in order to wait for a certain period of time estimated to end the process shown in FIG. 4 started by supplying power from the supply device 101a started by the process of S200A to the operation unit. It is processing.

  When the determination result obtained in S200B is yes, the processing unit 121a performs the process in S301.

  On the other hand, if the determination result from the process of S200B is no, the processing unit 121a performs the process of S200B again.

  When performing the process of S301, the processing unit 121a sends the disconnection instruction information to the connection unit 111a as the same process. By receiving the transmission, the connection unit 111a disconnects the connection between the terminals A and B.

  Next, the processing unit 121a reads the evaluation result recorded by the processes shown in FIGS. 4, 14, and 15 as the process of S302.

  And the process part 121a determines whether the evaluation result read by the process of S302 is level 1 as a process of S303. At this time, if the evaluation result is level 2 or level 3 or there is no evaluation result, it is determined that the evaluation result is not level 1.

  When the determination result obtained in step S303 is yes, the processing unit 121a performs step S307.

  On the other hand, the process part 121a performs the process of S304, when the determination result by the process of S303 is no.

  When performing the processing of S307, the processing unit 121a instructs the display unit 126a to display an OK evaluation result as the same processing. In response to the instruction, the display unit 126a displays an OK evaluation result.

  And the process part 121a sends connection instruction information with respect to the connection part 111a as a process of S308. The connection unit 111a receives the instruction information and performs connection between the terminals A and B.

  Then, the processing unit 121a performs the process of S309.

  When performing the process of S304, the processing unit 121a instructs the display unit 126a to display an NG evaluation result as the same process. In response to the instruction, the display unit 126a displays the evaluation result of NG.

  And the process part 121a determines whether the evaluation result read by the process of S302 is level 2 as a process of S305. At this time, if the evaluation result is level 3 or there is no evaluation result, it is determined that the evaluation result is not level 2.

  If the determination result in S305 is yes, the processing unit 121a performs the process in S308 described above.

  On the other hand, when the determination result in S305 is no, the processing unit 121a performs the process in S306.

  When performing the process of S306, the processing unit 121a sends the disconnection instruction information to the connection unit 111a as the same process. The connection unit 111a receives the instruction information and disconnects the terminals A and B.

  Then, the processing unit 121a performs the process of S309.

  When performing the processing of S309, the processing unit 121a determines whether to end the processing illustrated in FIG. 16 as the same processing. The processing unit 121a performs the determination by, for example, determining whether or not end information is input.

  If the determination result obtained in step S309 is yes, the processing unit 121a ends the process illustrated in FIG.

  On the other hand, when the determination result obtained in step S309 is no, the processing unit 121a performs the above-described processing in step S302 again.

  FIG. 17 is a table showing the display of the display unit 126a and the connection status of the connection unit 111a when the processing unit 121a performs the evaluation process shown in FIG. 15 and the evaluation result shown in FIG.

  The evaluation result is level 3 when the elapsed time required for the voltage drop is outside the predetermined range, and when the elapsed time is within the predetermined range but the noise level is high. Here, the elapsed time is the elapsed time recorded by the process of S106 in FIG. Further, the predetermined range is the predetermined time used for the processing of S107 in FIG. Moreover, a noise level is large means the case where a noise level is larger than threshold value Th6.

  When the evaluation result is level 3, the display unit 126a displays the NG evaluation result, and the connection unit 111a disconnects the terminals A and B shown in FIG. Even if the supply device 101a is connected to the power source by the disconnection, power is not supplied from the supply device 101a to the operation unit 131a.

  In addition, when the elapsed time required for the voltage drop is within a predetermined range and the noise level is medium, the evaluation result is level 2. Here, the medium noise level means that the noise level is equal to or less than the threshold Th6 and greater than the threshold Th7.

  When the evaluation result is level 2, the display unit 126a displays the NG evaluation result, but the connection unit 111a connects the terminals A and B shown in FIG. With this connection, power is supplied from the supply device 101a to the operating unit 131a by connecting the supply device 101a to a power source. This state represents that the supply device 101a is not suitable for supplying power to the operation unit 131a only by display to the user.

  When the elapsed time required for the voltage drop is within a predetermined range and the noise level is low, the evaluation result is level 1. Here, the low noise level means a case where the noise level is equal to or less than the threshold Th7.

  When the evaluation result is level 1, the display unit 126a displays the OK evaluation result, and the connection unit 111a connects the terminals A and B shown in FIG. With this connection, power is supplied from the supply device 101a to the operating unit 131a by connecting the supply device 101a to a power source. This state indicates to the user that the supply device 101a is suitable for supplying power to the operation unit 131a, and also enables power supply from the supply device 101a to the operation unit 131a. .

In the example in which the three-stage evaluation results described above are derived, the control unit 141a associates each evaluation result with a combination of the display operation by the display unit 126a and the connection operation by the connection unit 111a. Thereby, the control part 141a can provide a user with the said combination which is finer and appropriate.
[effect]
When the supply device performs the evaluation process, the processing unit 121a illustrated in FIG. 12 includes a time required for voltage reduction and a noise level when the supply device supplies power to the electrical equipment and then disconnects the supply device from the power source. Are used together. As described in Patent Document 3, it is known that noise may increase in the supplied power when the supply device is not suitable as an object for supplying power to the device. Accordingly, the processing unit 121a illustrated in FIG. 12 can derive a more accurate evaluation result by applying the noise level to the evaluation process.

  In the above description, in order to derive the evaluation result, the time required for a predetermined decrease in the voltage value when the connection with the power supply to the supply device is switched from connection to disconnection while the supply device is connected to the electrical device. The case of using was taken as an example. However, the evaluation result can be derived using a value representing the voltage value drop state other than the time. And what shows the said fall condition may be anything as long as it represents the drop situation of the said voltage value.

  For example, the drop state may be a time change of the voltage value.

  Alternatively, the drop state may be a value (similarity) representing the similarity between the time change of the voltage value and the time change of the reference voltage value.

  Furthermore, the value representing the drop state may be a value representing a characteristic of the voltage value over time. As a value representing the characteristic, in addition to the time required for the predetermined decrease in the voltage value, a predetermined slope or the like in a curve representing the time change of the voltage is assumed.

  FIG. 18 is a block diagram showing the configuration of the evaluation device 141x, which is the minimum configuration of the evaluation device of the present invention.

  The evaluation device 141x includes a voltage measurement unit 127x, an evaluation unit 121x, and an output unit 126x.

  The voltage measuring unit 127x measures a voltage value of an input from a supply device (not shown) that supplies predetermined DC power to an electric device (not shown) using power from the power source.

  The evaluation unit 121x derives a predetermined evaluation result for what represents the voltage value drop state due to disconnection of the supply device from the power supply after the supply device is connected to the power supply.

  The output unit 126x outputs the evaluation result.

  It is assumed that the power supplied from the supply device to the device including the operation unit is stopped by disconnecting the supply device from the power source. In this case, the drop state of the voltage supplied from the supply device to the operating unit is determined by the output impedance of the supply device, the output impedance of the device, and the current load of the device. Therefore, if the descent state of the supply device approximates a dedicated supply device designed for the device, it can be determined that the supply device is suitable as supplying power to the electrical equipment. .

  Therefore, the evaluation apparatus 141x has the effects described in the section [Effects of the Invention] with the above configuration.

  The embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments may be made without departing from the basic technical idea of the present invention.
