Description

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

  With the diversification of electronic devices, there are various AC adapters (a type of power supply device), and it is possible to inadvertently connect other AC adapters incorrectly. Here, AC is an abbreviation of alternating current.

  Misconnection of the AC adapter may damage the connected electrical equipment and in severe cases may lead to a burnout accident. The reason is that, if the current capacity of the AC adapter is too large, the electric device may cause an excessive current to flow to the electric device due to erroneous connection, which may generate heat due to the excessive current. On the other hand, if the current capacity of the AC adapter is too small, erroneous connection may cause the electric device to malfunction.

  The following method is disclosed for preventing erroneous connection of the AC adapter. For example, Patent Documents 1 and 2 disclose a method of monitoring an input voltage from an AC adapter to perform circuit protection. In addition, Patent Document 3 discloses a method of monitoring a noise level from an AC adapter to perform circuit protection.

  On the other hand, Patent Document 4 generates a predetermined voltage level while the power supply pressure is lower than the reference voltage level, and the power supply pressure exceeds the time for the power supply pressure to fall below the normal operating voltage. A method of generating the indication signal in response to a level is disclosed.

  However, because there are many AC adapters with the same rated voltage and different current capacities, the AC adapter determined to be appropriate by the above method of monitoring the input voltage from the AC adapter may not necessarily be appropriate. is there.

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

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

  The supply device 101a is a device for converting the power supplied from the power supply (not shown) into a predetermined DC power and supplying the converted 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, which is typically supplied through an outlet, and supplies the converted power to an electric device.

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

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

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

  The control unit 141a is a part that determines whether the supply device 101a is appropriate as a supply device that supplies power to the electric device 136a, and performs processing described later according to the determination result of the determination. Hereinafter, determination as to whether or not the supply device 101a is appropriate as a supply device for supplying power to the electric device 136a is referred to as “appropriate determination”, and evaluation about the supply device 101a based on the appropriate determination is referred to as “appropriate evaluation”. Let's say.

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

  The wiring indicated by the solid line in the power supply system 100a is a path of supplied power connecting the respective components shown in FIG. Further, the wiring indicated by the dotted line in the power supply system 100a is a signal path connecting the processing unit 121a and each configuration connected to the processing unit 121a.

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

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

  When the processing unit 121a determines that the disconnection has been performed, the processing unit 121a starts measuring the elapsed time by a timer (not shown) based on the determination time.

  Then, the processing unit 121a determines whether the voltage value sent from the voltage measurement unit 127a is smaller than a predetermined threshold value Th3.

  Then, when determining that the voltage value has fallen below the threshold value 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 the elapsed time is in a range of a predetermined elapsed time.

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

  On the other hand, when the processing unit 121a does not determine that the elapsed time is in the range, the processing unit 121a instructs the display device to display that the supply device 101a is not suitable for supplying power to the electric device 136a. send. Then, when the terminals A and B are connected, the processing unit 121a sends instruction information to instruct disconnection between the terminals A and B to the connection unit 111a. When the terminals A and B are already disconnected, the processing unit 121a maintains the disconnection.

  The display unit 126a displays the instructed content in accordance with the instruction information from the processing unit 121a. The display unit 126a is, for example, a display.

  The connection unit 111 a is a switch that performs connection and disconnection between the terminals A and B according to the information sent from the processing unit 121 a.

  The sub power supply 116a is disconnected from the power supply of the supply device 101a after the supply device 101a is connected to the power supply, and when the voltage input thereby drops, the necessary power is supplied for a predetermined period. Do. The targets to which power is supplied 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 146.

  When the 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. The predetermined operation is, for example, a communication operation associated with a call or the like when the electric device 136a is a mobile phone.

  FIG. 2 is a conceptual diagram showing a configuration of a processing unit 121b which is an example of the processing unit 121a shown in FIG.

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

  The arithmetic unit 164a performs an operation on the process 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 the information held by the instruction of the arithmetic unit 164a to the arithmetic unit 164a.

  The timer 163a measures the elapsed time in accordance with an instruction from the calculation unit 164a. Then, the timer 163a sequentially sends the measured time to the computing unit 164a.

  Each component of the processing unit 121 b operates by the power sent to the terminal D. The wiring between the terminal D and each component is not shown in FIG.

  FIG. 3 is a conceptual diagram showing a configuration of a secondary power supply 116b which is an example of the secondary power supply 116a shown in FIG.

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

  The capacitance of the capacitor 138a is an evaluation process performed by the processing unit 121a and a process performed based on the evaluation result, and a current and a voltage necessary for operations performed by the voltage measurement unit 127a, the display unit 126a, and the connection unit 111a along with these processes. And from the operating time. Here, the evaluation is an evaluation as to whether the supply device 101a is a suitable supply device to supply power to the electric 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. Note that the upper, lower, left, and right in the description of the embodiment indicate upper, lower, left, and right in the drawing to be described unless otherwise specified.

  As described above, from the supply device 101a shown in FIG. 1, power (voltage) is supplied to the left end of the diode 137a through the terminal E. 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. Then, as described above, even when the power supplied from the power supply device 101a to the electric device 136a through the connection portion 146 is reduced by disconnecting the power supply device 101a from the power supply, the capacitor 138a keeps the power for a predetermined period. Continue supply. The components to which power is supplied are the connection unit 111a, the voltage measurement unit 127a, the processing unit 121a, and the display unit 126a.

  The diode 137a cuts off the current from the right to the left of the diode 137a. Accordingly, no power is supplied from the capacitor 138a to the operation unit 131a through the connection unit 111a.

The secondary power supply 116a shown in FIG. 1 may be a simple battery other than the secondary 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 evaluation processing performed by the processing unit 121a illustrated in FIG. The evaluation is an evaluation as to whether the supply device 101a is a suitable supply device to supply power to the electrical device 136a.

  First, in step S101, the processing unit 121a determines whether the voltage value sent from the voltage measurement unit 127a exceeds the threshold Th1. Here, the threshold Th1 is a threshold for the voltage value predetermined for the process of S101. The process of S101 is a process performed to determine whether the supply device 101a shown in FIG. 1 is connected to the connection unit 146 and the supply device 101a is connected to the power supply.

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

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

  When the processing unit S <b> 103 is performed, the processing unit 121 a determines whether the supply device 101 a has been disconnected from the power supply, as the same processing. The said cutting | disconnection can be performed by the person's exterior etc. as mentioned above. The processing unit 121a performs the determination, for example, by determining that the amount of decrease in the voltage value within a unit time exceeds a predetermined value.

  If the determination result in the process of S103 is yes, the processing unit 121a performs the process of S104.

  On the other hand, when the determination result by 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 measurement of an elapsed time as the same process.

  Then, as the process of S105, the processing unit 121a determines whether the voltage value is less than the threshold value Th3. Here, the threshold Th3 is a threshold for the voltage value predetermined for the process of S105. The threshold value Th3 is determined, for example, by selecting an appropriate value from the time change of the voltage value when using a supply device known to be suitable for supplying power to the electric device 136a.

  If the determination result by the process of S105 is yes, the processing unit 121a performs the process of S106.

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

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

  Then, as the process of S107, the processing unit 121a determines whether the elapsed time is within a predetermined range. The predetermined range is a range of elapsed time predetermined for the process of S107.

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

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

  In the case of 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 suitable for supplying 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 device 101a is unsuitable as one for supplying power to the electric device 136a. The processing 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 showing an example of a processing flow of processing performed by the processing unit 121 a based on an evaluation result by the processing shown in FIG. 4.

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

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

  Next, in step S200B, the processing unit 121a starts measuring time, and then determines whether a predetermined time has elapsed. The process of S200B is performed to wait for the elapse of a predetermined time for which it is estimated that the process shown in FIG. 4 started by the power supply from the supply apparatus 101a to the operation unit started by the process of S200A is completed. It is a process.

  If the determination result by the process of S200B is yes, the processing unit 121a performs the process of S201.

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

  When performing the process of S201, the processing unit 121a sends, to the connection unit 111a, instruction information for disconnecting the terminals A and B shown in FIG. 1 as the process. The connection unit 111 a disconnects the terminals A-B in response to the instruction information.

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

  Then, as the processing of S203, the processing unit 121a determines whether the evaluation result read in the processing of S202 is OK. 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 by the process of S203 is yes, the processing unit 121a performs the process of S203A.

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

  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 as the same processing. In response to the instruction information, the display unit 126a displays that the evaluation result is OK. The display is, for example, character display of “good connection”, continuous lighting of a green lamp, or the like. The display unit 126a may express that the evaluation result is OK by voice or vibration along with or instead of the display.

  Then, in the processing of S204, the processing unit 121a sends, to the connection unit 111a, instruction information indicating an instruction to connect the terminals A and B shown in FIG.

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

  On the other hand, when performing the processing of S203B, the processing unit 121a sends instruction information for instructing the display unit 126a to display that the evaluation result is NG as the same processing. In response to the instruction information, the display unit 126a displays that the evaluation result is NG. The display is, for example, character display of “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 along with or instead of the display.

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

  When the processing of step S205 is performed, the processing unit 121a determines whether to end the processing illustrated in FIG. 5 as the processing. The processing unit 121a performs the determination, for example, by determining the presence / absence of input of end information from the outside.

  If 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 of S205 is no, the processing unit 121a performs the process of S202 again.

  If the supply device 101a shown in FIG. 1 is suitable for supplying power to the electric device 136a, the electric device 136a shown in FIG. 1 obtains an evaluation result indicating that it is OK by the process of S108 in FIG. Then, the electric device 136a displays the evaluation result indicating OK by the process of S203A shown in FIG. 5 based on the evaluation result indicating the OK. The electric device 136a further enables the power from the supply device 101a to be supplied to the operation unit 131a by the process of S204 based on the evaluation result indicating that the OK is performed. Accordingly, when the supply device 101a is connected to the power supply in this state, the supply of power from the supply device 101a to the operation unit 131a is performed.

  On the other hand, when the supply device 101a shown in FIG. 1 is not suitable for supplying power to the electric device 136a, the electric device 136a obtains an evaluation result indicating NG by the process of S109 of FIG. Then, the electrical device 136a displays the evaluation result indicating NG by the process of S203B shown in FIG. 5 based on the evaluation result indicating the NG. The electric device 136a further holds the state in which the power from the supply device 101a is not supplied to the operation unit 131a in the process of S201 based on the evaluation result indicating the NG. Therefore, when the supply device 101a is connected to the power supply in this state, the supply of power from the supply device 101a to the operation unit 131a is not performed.

In this manner, damage to the operation unit 131a that occurs when the control unit 141a and the supply device 101a are not suitable for supplying power to the electric device 136a can be suppressed.
[effect]
When the supply device 101a is connected to the power supply and then disconnected from the power supply with the supply device 101a connected to the connection unit 146, the control unit 141a illustrated in FIG. The evaluation result according to the appropriate evaluation is obtained. The control unit 141a obtains the evaluation result from the time required for a predetermined drop of 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 drop condition of the voltage 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 condition is a drop condition of the voltage of the input from the connection unit 146 when the supply device 101a is disconnected from the power supply after supplying power from the supply device 101a to the operation unit 131a of the electric device 136a. is there. Thus, if the descent status of the feeding device 101a is similar to the descent status of the feeding device designed for the electrical device 136a, the feeding device is suitable for supplying power to the electrical device. Can be judged.

  And the time which the above-mentioned descent takes is a value showing the descent situation. Therefore, if the time required for the descent is similar to the time required for the descent of the supply device designed for the electrical device 136a, the supply device 101a is suitable as a device for supplying power to the electrical device 136a. Can be determined.

  The control unit 141a presents the evaluation result to the user etc. and, based on the evaluation result, performs processing to enable or disable the power supply to the operation unit 131a. As described in [Background Art], when the current capacity of the supply device is too large, the electric device may cause an excessive current to flow to the electric device due to a misconnection, which may cause heat generation due to the excess current, etc. is there.

The control unit 141a disables the power supply to the operation unit 131a when the supply device 101a is not suitable for supplying power to the electric device 136a, and thus the control unit 141a may generate the operation unit 131a that may be generated due to excessive current. You can reduce the damage.
Second Embodiment

  The connection unit 151 a is a switch that performs connection and disconnection between the terminals A and B according to instruction information sent from the processing unit 121 a.

  The supply device 101a is connected to a power supply (not shown).

  The control unit 141a illustrated in FIG. 6 includes a signal path represented by a dotted line between the processing unit 121a and the connection unit 146, in addition to the configuration included in the control unit 141a illustrated in FIG.

  Then, the processing unit 121a illustrated in FIG. 6 performs the following operation as necessary in addition to the operation performed by the processing unit 121a illustrated in FIG. That is, the processing unit 121a illustrated in FIG. 6 transmits instruction information for instructing the supply device 101a to connect and disconnect the terminals GH by the connection unit 151a.

The case where the processing unit 121a illustrated 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 a process of replacing the processes of S101 and S103 shown in FIG.

  The processing unit 121a illustrated in FIG. 6 transmits connection instruction information to the connection unit 151a of the supply device 101a as the process of S102-2 after the start illustrated in FIG. The connection unit 151a that has received the connection instruction information performs connection between the terminals GH.

  Then, as the process of S102-3, the processing unit 121a starts measuring time, and thereafter determines whether a predetermined time has elapsed. In the process of S102-3, the connection between the terminals GH by the connection unit 151a is performed by the connection instruction information sent by the process of S102-2, and the power from the supply device 101a to the operation unit 131a of the electric device 136a This process is performed to wait for the supply to be performed.

  If 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 process of S102-4, the processing unit 121a sends disconnection instruction information to the connection unit 151a as the same process. The connection unit 151a that has received the disconnection instruction information disconnects the connection between the terminals GH.

  Then, the connection unit 151a performs the process of S104 illustrated in FIG.

  In the power supply system 100a shown in FIG. 1, it is necessary to perform the connection to the power supply of the supply device 101a and the subsequent disconnection by an operation outside the power supply system 100a by a person's work or the like. On the other hand, in the power supply system 100a shown in FIG. 6, the power supply system 100a automatically performs the connection to the power supply of the supply device 101a and the subsequent disconnection.

  The processing flow example of the processing performed by the control unit 141a illustrated in FIG. 6 and performed based on the evaluation result by the processing illustrated in FIG. 7 is the processing of S203-2 illustrated in FIG. 8 between yes in S203 illustrated in FIG. It is inserted.

  The description of the power supply system 100a shown in FIG. 9 is the same as the description of the power supply system 100a shown in FIG. 1 except for the following. However, when the following description contradicts the explanation of FIG. 1, the following description is given priority.

  The supply device 101a illustrated in FIG. 9 includes a communication unit 125a in addition to the configuration of the supply device 101a illustrated in FIG.

  The communication unit 125a performs wireless communication with a communication unit 124a described later.

  The control unit 141a illustrated in FIG. 9 includes a communication unit 124a in addition to the configuration of the control unit 141a illustrated in FIG.

The processing unit 121a illustrated in FIG. 9 performs the following operation as necessary in addition to the operation performed by the processing unit 121a illustrated in FIG. That is, the processing unit 121a illustrated in FIG. 9 transmits instruction information for instructing connection and disconnection between the terminals G and H by the connection unit 151a to the supply device 101a through the communication unit 124a and the communication unit 125a. The case where 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 a process of replacing the process of S101 and S103 shown in FIG.

  After the start shown in FIG. 4, the processing unit 121a illustrated in FIG. 9 instructs the communication unit 124a to send connection instruction information to the communication unit 125a as the process of S102-2a. The communication unit 124a that has received the instruction 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 the terminals GH.

  Next, in step S102-3, the processing unit 121a starts measuring time, and then determines whether a predetermined time has elapsed. In the process of S102-3, the connection between the terminals GH by the connection unit 151a is performed by the connection instruction information sent by the process of S102-2, and the power from the supply device 101a to the operation unit 131a of the electric device 136a This process is performed to wait for the supply to be performed.

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

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

  When performing the process of S102-4a, the processing unit 121a instructs the communication unit 124a to send disconnection instruction information to the communication unit 125a as the same process. The communication unit 124a that has received the instruction sends disconnection instruction information to the communication unit 125a. The disconnection instruction information is sent from the communication unit 125a to the connection unit 151a. And the connection part 151a cuts between the terminals GH.

  Then, the connection unit 151a performs the process of S104 illustrated in FIG.

  FIG. 11 is a conceptual diagram showing the processing to be inserted into FIG. 5 performed by the processing unit 121a shown in FIG.

  Next to yes of S203 shown in FIG. 5, the processing unit 121a instructs the communication unit 124a to send connection instruction information directed to the connection unit 151a to the communication unit 125a as the process of S203-2a. The communication unit 124a that has received the instruction sends connection instruction information to the connection unit 151a to the communication unit 125a. Then, upon receiving the transmission, the communication unit 125a sends the connection instruction information to the connection unit 151a. Then, the communication unit 125a causes the connection unit 151a to perform connection between the terminals GH.

  In the power supply system 100a shown in FIG. 1, it is necessary to connect the power supply device 101a to the power supply and to disconnect the power supply device 101a from the outside of the power supply system 100a by a person's work or the like. On the other hand, in the power supply system 100a shown in FIG. 9, the power supply system 100a automatically performs the connection to the power supply of the supply device 101a and the subsequent disconnection.

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 shown in FIG. 9 wirelessly transmits and receives information between the supply device 101a and the electric device 136a. Therefore, the power supply system 100a illustrated in FIG. 9 can omit the wired signal path and the connection mechanism between the signal paths in the connection unit 146.
[effect]
The control unit 141a shown in FIG. 9 has a configuration similar to that of the control unit 141a shown in FIG. 6, and exhibits the same effect as the control unit shown in FIG.

In addition, the power supply system 100a illustrated in FIG. 9 wirelessly transmits instruction information from the processing unit 121a to the connection unit 151a. Therefore, the power supply system 100a shown in FIG. 9 can omit the wired signal path shown in FIG. 6 and the connection mechanism inside the connection portion 146 between the signal paths.
Fourth Embodiment
The fourth embodiment is an embodiment of the electric device that performs the appropriate determination in consideration of the noise level related to the input from the supply device to the electric device.
[Configuration and operation]
FIG. 12 is a conceptual diagram showing a configuration of a power supply system 100a which 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 shown in FIG. 12 is the same as the description of the power supply system 100a shown in FIG. 1 except for the following. However, when the following description contradicts the explanation of FIG. 1, the following description is given priority.

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

  The noise measurement unit 128 a 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 of a frequency higher than a predetermined frequency at the input. The noise measurement unit 128a is, for example, a noise measurement device capable of measuring an AC voltage of noise level.

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

  The terminal J of the noise measurement unit 128a is connected to the sub power supply 116a. When the voltage level of the input from the connection unit 146 is lowered due to the supply device 101a being disconnected from the power supply, it is necessary for the noise measurement unit 128a to operate from the secondary power supply 116a to the noise measurement unit 128a. Power is supplied.

  The processing unit 121a derives an evaluation result related to the appropriate evaluation based on the voltage value sent from the voltage measurement unit 127a and the noise level sent from the noise measurement 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 based on the evaluation result. Specific examples of the control will be described later in the section of the processing flow.
Processing flow
The first example of the process flow of the evaluation process performed by the processing unit 121a illustrated in FIG. 12 is a process of S107-1 and S107-2 illustrated in FIG. 13 between yes of S107 illustrated in FIG. 4 and the processes of S108 and S109. Processing is inserted.

  FIG. 13 is a conceptual diagram showing a process performed by the processing unit 121a shown in FIG. 12 and inserted in the evaluation process shown in FIG.

  The processing unit 121a illustrated in FIG. 12 records the noise level sent from the noise measuring unit 128a as the process of S107-2 following the yes of S107 illustrated in FIG.

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

  The processing unit 121a performs the process of S109 illustrated in FIG. 4 when the determination result of the process of S107-2 is yes.

  On the other hand, when the determination result by the process of 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 device 101a to the information used for the evaluation process. As disclosed in Patent Document 3, noise may increase in the supplied power if the supply device is not suitable for supplying power to the electric device. 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 two steps. However, as described below, the evaluation result may have three or more stages. Then, as described below, the processing unit 121a may perform processing to be performed based on the evaluation result based on the evaluation result of the three or more stages.

  The second processing flow example of the evaluation processing performed by the processing unit 121a shown in FIG. 12 inserts the processing shown in FIG. 14 into the processing flow shown in FIG. 4 and further performs the processing of S108 and S109 shown in FIG. Is replaced by the process shown in FIG.

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

  The processing unit 121a records Level 2 in the evaluation result as the process of S102 after the yes of S107 shown in FIG. The evaluation results of Level 2 are in the middle of the three evaluation results. The process performed by the processing unit 121a in the case of level 2 will be described later with reference to FIG.

  After S102, the processing unit 121a performs the process of S103 shown in FIG.

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

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

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

  If the determination result in the process of S111 is yes, or if the determination result in the process of S107 shown in FIG. 4 is no, the processing unit 121a performs the process of S112.

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

  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 device 101a is most unsuitable for supplying power to the operation unit among the three evaluation results. The process performed by the processing unit 121a in the case of level 3 will be described later with reference to FIG.

  Then, the processing unit 121a ends the processing illustrated in FIG. 4, FIG. 14, and FIG.

  When performing the processing of S112, the processing unit 121a determines whether the noise level sent from the noise measurement unit 128a is higher than the threshold Th7 as the same processing. Here, the threshold Th7 is a threshold for the noise level sent from the noise measurement unit 128a, which is predetermined for the process of S111. The threshold Th7 is a value lower than the above-mentioned threshold Th6.

  If the determination result in the process of S113 is yes, the processing unit 121a ends the process illustrated in FIG. 4, FIG. 14 and FIG. Thereby, the processing unit 121a maintains the evaluation result of level 2 recorded by the process of S102 shown in FIG.

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

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

  Then, the processing unit 121a ends the processing illustrated in FIG. 4, FIG. 14, and FIG.

  Thus, the processing unit 121a illustrated in FIG. 12 holds the evaluation result of any one of level 1 to level 3 by the processing illustrated in FIG. 4, FIG. 14 and FIG.

  FIG. 16 is a conceptual diagram illustrating an example of a processing flow of processing performed by the 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 further connected to a power supply.

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

  Next, in step S200B, the processing unit 121a starts measuring time, and then determines whether a predetermined time has elapsed. The process of S200B is performed to wait for the elapse of a predetermined time for which it is estimated that the process shown in FIG. 4 started by the power supply from the supply apparatus 101a to the operation unit started by the process of S200A is completed. It is a process.

  The processing unit 121a performs the process of S301 when the determination result of the process of S200B is yes.

  On the other hand, when the determination result by 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 disconnection instruction information to the connection unit 111a as the same process. The connection part 111a cut | disconnects the connection between terminal AB by receiving the said delivery.

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

  Then, the processing unit 121a determines whether the evaluation result read in the process of S302 is level 1 as the 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.

  If the determination result by the process of S303 is yes, the processing unit 121a performs the process of S307.

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

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

  Then, the processing unit 121a sends connection instruction information to the connection unit 111a as the process of S308. The connection unit 111 a 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 the evaluation result of NG as the same process. In response to the instruction, the display unit 126a displays the evaluation result of NG.

  Then, as the process of S305, the processing unit 121a determines whether the evaluation result read in the process of S302 is level 2. 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 of S308 described above.

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

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

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

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

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

  On the other hand, when the determination result by the process of S309 is no, the processing unit 121a performs the process of S302 described above 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 process performed by the evaluation result shown in FIG.

  When the elapsed time required for the voltage reduction is outside the predetermined range, and when the elapsed time is within the predetermined range but the noise level is large, the evaluation result is level 3. Here, the elapsed time is the elapsed time recorded by the process of S106 of FIG. The predetermined range is a predetermined time used for the process of S107 in FIG. Further, the noise level being large means that the noise level is larger than the threshold Th6.

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

  In addition, when the elapsed time required for the voltage reduction 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 larger than the threshold Th7.

  When the evaluation result is level 2, the display unit 126a displays the evaluation result of NG, but the connection unit 111a connects terminals A and B shown in FIG. By connecting the supply device 101a to the power supply through the connection, power is supplied from the supply device 101a to the operation unit 131a. The state indicates to the user that the supply device 101a is not suitable as power supply to the operation unit 131a only by display.

  If the elapsed time required to reduce the voltage is within a predetermined range and the noise level is small, the evaluation result is level 1. Here, that the noise level is small means that 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 evaluation result of OK, and the connection unit 111a connects the terminals A and B shown in FIG. By connecting the supply device 101a to the power supply through the connection, power is supplied from the supply device 101a to the operation unit 131a. The state indicates to the user by display that the supply device 101a is suitable for supplying power to the operation unit 131a, and enables power supply from the supply device 101a to the operation unit 131a. .

In the example which leads the evaluation result of three steps explained above, control part 141a matches the combination of each evaluation result, the display operation by display part 126a, and the connection operation by connection part 111a. Thereby, the control unit 141a can provide the user with the more detailed and appropriate combination.
[effect]
In the processing unit 121a illustrated in FIG. 12, when the supply device performs the evaluation process, the time required for the voltage drop and the noise level when the supply device supplies power to the electric device and then the supply device is disconnected from the power supply. Use together. As described in Patent Document 3, it is known that when the supply device is not suitable for supplying power to the device, noise may increase in the supplied power. 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, when deriving the evaluation result, when the connection with the power supply to the supply device is switched from the connection to the disconnection with the supply device connected to the electric device, the time required for the predetermined reduction of the voltage value is The case of use is taken as an example. However, for the derivation of the evaluation result, it is also possible to use one representing the drop condition of the voltage value other than the time. And what shows the said falling condition may be anything as long as it shows the falling condition of the said voltage value.

  For example, it may be a time change of the voltage value that represents the falling condition.

  Alternatively, the value representing the drop condition 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 falling condition may be a value representing the characteristic of the time change of the voltage value. As a value representing the feature, in addition to the time required for the predetermined reduction of the voltage value described above, a predetermined slope or the like in a curve representing a time change of the voltage is assumed.

  FIG. 18 is a block diagram showing the configuration of an 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 measurement unit 127x measures the voltage value of the input from the supply device (not shown) that supplies predetermined DC power to the electric device (not shown) by the power from the power supply.

  The evaluation unit 121x derives a predetermined evaluation result on what represents the drop condition of the voltage value due to the disconnection of the supply device from the power supply after the connection of the supply device to the power supply.

  The output unit 126x outputs the evaluation result.

  It is assumed that the supply of the power supplied from the supply device to the device including the operation unit is stopped by disconnecting the supply device from the power supply. In that case, the drop condition of the voltage supplied from the supply device to the operation unit is determined by the output impedance of the supply device, the output impedance of the device, and the current load of the device. Thus, if the descent situation of the supply device is similar to a dedicated supply device designed for the device, the supply device can be judged to be suitable for supplying power to the electrical device .

  Therefore, the evaluation device 141x exhibits the effect described in the section of the [effect of the invention] by the above configuration.
