Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing an example of the appearance of a determination apparatus 1 in the present invention. The determination apparatus 1 determines the quality of the substrate accommodated in the own apparatus. Here, the substrate is, for example, a substrate used for a transmission device on the station side. As an example, the substrate may be a substrate used on a 3.4 KHz dedicated line. The determination device 1 includes the touch panel 10 and the storage unit 20.

The touch panel 10 displays various information and receives an input of an instruction from the user.
The accommodation unit 20 is an accommodation port for accommodating a substrate (hereinafter referred to as a “target substrate”) which is a target of the quality determination. Here, the quality determination is processing to determine whether or not there is a problem with the target substrate itself or the function, and for example, the quality of the power supply system at the time when the target substrate is accommodated in the storage unit 20 for quality determination. There are determination and determination of good or bad in a function test executed after the target substrate is stored in the storage unit 20.

  In the quality determination of the power supply system, the quality of the target substrate is determined based on whether the power supplied from the determination device 1 is supplied to the target substrate. In the quality determination in the function test, the quality of the target substrate is determined based on whether the function of the target substrate is equal to or higher than a predetermined performance. In this embodiment, as a functional test, a case of performing level measurement, transmission loss frequency measurement, execution return loss measurement, and no-talk time noise measurement will be described as an example. In addition, an interface for connecting to the target substrate is provided in the storage unit 20.

FIG. 2 is a view showing a configuration example of a target substrate.
FIG. 2A is a view showing a hardware configuration of the target substrate 21, and FIG. 2B is a view showing an example of an LED lamp provided on the target substrate 21.
The target substrate 21 corresponds to 2 W type setting and 4 W type setting as the line setting. As shown in FIG. 2A, the target substrate 21 includes an input / output connector 22, a control circuit 23, and a light emitting unit 24. The input / output connector 22 is an interface for connecting the determination device 1 and the target substrate 21. The input / output connector 22 outputs the signal output from the determination device 1 to the control circuit 23, and outputs the signal output from the control circuit 23 to the determination device 1.

  The control circuit 23 is a circuit that controls the target substrate 21. For example, when power is supplied from the determination device 1, the control circuit 23 causes the light emitting unit 24 to light. Specifically, when power is supplied from the determination device 1, the control circuit 23 causes the light emitting unit 24 to light by outputting a signal for lighting the light emitting unit 24 to the light emitting unit 24. When power is supplied from the determination device 1, the control circuit 23 outputs a notification that power is received to the determination device 1 via the input / output connector 22. Further, the control circuit 23 switches between the 2 W setting and the 4 W setting according to an instruction from the determination device 1.

  Further, as illustrated in FIG. 2B, the light emitting unit 24 includes a first lamp 241 and a second lamp 242. The first lamp 241 and the second lamp 242 are, for example, LED (Light Emitting Diode) lamps, and are lit in response to an instruction from the control circuit 23. The light emitting unit 24 lights either the first lamp 241 or the second lamp 242 in accordance with the signal output from the control circuit 23. The first lamp 241 emits light when power is supplied. The second lamp 242 emits light when the lighting test of the LED lamp is instructed.

The display control unit 111 controls the display of the touch panel 10. The input / output control unit 112 controls input / output of signals of the input / output connector 13 and the input / output unit 15. The signal generation unit 113 generates various signals. For example, the signal generation unit 113 generates a signal for lighting the second lamp 242 for test (hereinafter, referred to as “test signal”) and a function test signal.

  The measurement unit 114 measures the level diagram, the transmission loss frequency, the execution return loss, and the no-talk time noise when the functional test is performed. The determination unit 115 determines whether the target substrate 21 is good or bad. For example, the determination unit 115 determines the quality of the target substrate 21 based on the power supply by the power supply unit 12. Further, for example, the determination unit 115 determines the quality of the target substrate 21 based on the measurement result of the measurement unit 114.

The feed unit 12 feeds power to the target substrate 21 when the target substrate 21 is connected to the input / output connector 13.
The input / output connector 13 is an interface for connecting the own device and the target substrate 21. The input / output connector 13 inputs / outputs a signal from the own device to the target substrate 21 and a signal from the target substrate 21 to the own device.

The test result storage unit 14 stores the result of the functional test as storage data. For example, the test result storage unit 14 associates and stores identification information (for example, No.) for identifying the storage destination and the result of the functional test.
The input / output unit 15 is an interface for connecting the own apparatus and another apparatus (for example, an information processing apparatus such as a personal computer). The input / output unit 15 outputs storage data in a predetermined format to another connected device. Here, the predetermined format is, for example, a format of a CSV file.

The screen shown in FIG. 5 is displayed on the touch panel 10 after the function test button 32 is selected on the selection screen 30 and the function test is performed. In the following description, the screen shown in FIG. 5 is described as a functional test result display screen. In the function test result display screen, an inspection item 37 on which the function test is performed and a determination result 38 of the function test on the inspection item 37 are displayed in association with each other. In FIG. 5, the determination results for the items of the level diagram and the transmission loss frequency characteristic, the determination results for the item of the execution return loss, and the determination results for the no-talk time noise item are displayed in different modes. The display control unit 111 executes such display based on the following three display criteria. As shown in FIGS. 6 and 7, there are a plurality of items to be measured (hereinafter referred to as "measurement items") for each of the inspection items of the function test.

(Display standard)
1. All the measurement results of the measurement items in the inspection item by the function test are the values specified in the specifications of the target substrate 21 (hereinafter referred to as “specified values”) and values considered to be better than the specified values ( Hereinafter, it is referred to as “recommended threshold”) or more. When all the measurement results of the measurement item in the inspection item by the function test are above the specified value and some or all are below the recommended threshold value When part or all of the measurement results of the measurement item in the inspection item by the function test is less than the specified value

  For example, in FIG. 5, the inspection items of the level diagram and the transmission loss frequency characteristic are: The inspection items of the execution return loss that satisfy the display criteria of 1. The inspection items of the noise during call that satisfy the display criteria Meeting the display criteria of. In this case, as shown in FIG. 5, the display control unit 111 displays the determination result in the display mode in accordance with the satisfied condition of the display standard.

6 and 7 are diagrams showing an example of detailed screen data of each function test.
FIG. 6 (A) shows the measurement result for the measurement item of the level diagram, FIG. 6 (B) shows the measurement result for the measurement item of the transmission loss frequency, and FIG. 7 (A) shows the execution return loss FIG. 7B is a diagram showing the measurement result for the measurement item of no-talk time noise. As shown in FIGS. 6 and 7, in the measurement results for the measurement items, the display control unit 111 displays in a different manner depending on whether the measurement result is equal to or greater than the specified value or whether it is equal to or greater than the recommended threshold. Do.

  For example, FIG. 6 shows that the measurement result for the measurement item of the level diagram and the measurement result for the measurement item of the transmission loss frequency characteristic are all above the recommended threshold. Also, for example, in FIG. 7A, among the measurement results for the measurement item of the execution return loss, a part of the measurement results (measurement results of 0.60 KHz) is not less than the specified value and less than the recommended threshold. It is shown. Further, for example, in FIG. 7 (B), it is shown that among the measurement results for the measurement item of no-call noise, some measurement results (measurement results of no-call noise of 4 W) are less than the specified value. ing.

FIG. 8 is a diagram showing an example of a list screen of stored data.
The list screen of stored data is a screen displayed on the touch panel 10 when the result display button 33 is selected on the selection screen 30. As shown in FIG. 1 to No. A storage area 39 of twenty twenty stored data is displayed. As shown in FIG. 8, the display control unit 111 displays the identification number for identifying the stored data in a different manner based on the measurement result of the stored data stored. For example, no. 8-No. 10, no. 14 and no. In 15, all the measurement items have data above the recommended threshold, that is, in all the inspection items of the functional test, all the measurement items have data above the recommended threshold. In this case, the display control unit 111 changes and displays the display mode so as to indicate that.

FIG. 9 is a flowchart showing the flow of processing of the determination device 1. In addition, in FIG. 9, the process of the quality determination of the object board | substrate in the time of a board | substrate being accommodated in the accommodating part 20 of the determination apparatus 1 is demonstrated.
When the substrate is accommodated in the accommodation unit 20, the input / output control unit 112 instructs the feed unit 12 to supply power. The power supply unit 12 supplies power to the target substrate via the input / output connector 13 according to the instruction of the input / output control unit 112 (step S101). The determination unit 115 determines whether or not there is a response from the target substrate via the input / output connector 13 (step S102). Specifically, the determination unit 115 determines whether or not there is a response from the target substrate based on whether or not a notification indicating that power is being received via the input / output connector 13 is obtained. When the notification that power is being received through the input / output connector 13 is obtained, the determination unit 115 determines that there is a response from the target substrate. When the notification that power is being received through the input / output connector 13 is not obtained, the determination unit 115 determines that there is a response from the target substrate.

  If there is a response from the target substrate (YES in step S102), the determination unit 115 then determines whether the target substrate stored in the storage unit 20 is the correct target substrate (step S103). Here, the correct target substrate refers to a target substrate that is the target to be originally subjected to the quality determination in the determination apparatus 1. In the present embodiment, for example, the correct target substrate is a substrate used for the transmission apparatus on the station side. The determination as to whether or not the target substrate is the correct target substrate is performed as follows. When a signal is given to a certain terminal of the input / output connector 13 and a signal is obtained from a predetermined terminal, the determination unit 115 determines that the target substrate stored in the storage unit 20 is the correct target substrate. . On the other hand, when a signal is given to a certain terminal of the input / output connector 13 and no signal is obtained from a predetermined terminal, the determination unit 115 determines that the target substrate stored in the storage unit 20 is not the correct target substrate. It is determined that

  If the target substrate stored in the storage unit 20 is the correct target substrate (YES in step S103), the determination unit 115 outputs, to the display control unit 111, a notification that the target substrate is the correct target substrate. When receiving the notification that the target substrate is the correct target substrate, the display control unit 111 displays a selection screen on the touch panel 10 (step S104).

  Also, if there is no response from the target substrate in the process of step 102 (step S102-NO), or if the target substrate stored in the storage unit 20 in the process of step 103 is not the correct target substrate (step S103) The determination unit 115 outputs a notification to that effect to the display control unit 111. The display control unit 111 displays an error screen on the touch panel 10 when it receives a notification that there is no response from the target substrate or a notification that the target substrate stored in the storage unit 20 is not the correct target substrate. (Step S105).

FIG. 10 is a flowchart showing the flow of the process of the determination apparatus 1. In addition, in FIG. 10, a selection screen is displayed on the determination apparatus 1, and the process of the quality determination of the object board | substrate after an instruction | indication is input is demonstrated.
The determination unit 115 determines an instruction input via the touch panel 10 (step S201). Specifically, the determination unit 115 determines which of the LED test, the function test, and the result display the instruction input through the touch panel 10 is. Although the brightness adjustment is also displayed on the selection screen, the description of the brightness adjustment is omitted because it has been described in FIG.

  When the LED test instruction is input (step S201-LED test), the determination unit 115 outputs, to the input / output control unit 112, a notification that the LED test instruction has been input. When receiving the notification that the LED test instruction has been input, the input / output control unit 112 instructs the signal generation unit 113 to generate a test signal. The signal generation unit 113 generates a test signal in accordance with an instruction from the input / output control unit 112 (step S202).

  When the test signal is generated by the signal generation unit 113, the input / output control unit 112 executes the LED test (step S203). Specifically, the input / output control unit 112 controls the signal generation unit 113 to output the test signal to the target substrate 21 through a specific terminal of the input / output connector 13. Thereby, the test signal is output to the target substrate 21. The control circuit 23 lights the second lamp 242 based on the test signal input through the specific terminal of the input / output connector 22.

  Further, when an instruction of a function test is input in the process of step S201 (step S201-function test), the determination unit 115 outputs, to the display control unit 111, a notification that the instruction of the function test is input. When the display control unit 111 receives the notification that the function test instruction has been input, the display control unit 111 displays the storage destination candidate on the touch panel 10. Specifically, the display control unit 111 displays a screen similar to the screen shown in FIG. 8 on the touch panel 10, and receives the selection of the storage destination from the user. When the display control unit 111 displays the storage destination candidate on the touch panel 10, the storage destination of the identification number not stored in the test result storage unit 14 is the identification number stored in the test result storage unit 14 It may be displayed in a manner different from the storage destination. For example, the display control unit 111 may display the storage destination of the identification number stored in the test result storage unit 14 in gray scale so as not to be selectable.

  When the storage destination candidate is selected through the touch panel 10, the input / output control unit 112 instructs the signal generation unit 113 to generate a function test signal. The input / output control unit 112 instructs the signal generation unit 113 to generate the next functional test signal each time one functional test is completed. For example, the input / output control unit 112 instructs the signal generation unit 113 to generate a function test signal as follows. First, the input / output control unit 112 instructs the signal generation unit 113 to generate a function test signal related to the level diagram. When the functional test on the level diagram is completed, next, the input / output control unit 112 instructs the signal generation unit 113 to generate a functional test signal on transmission loss frequency characteristics. When the function test on the transmission loss frequency characteristic is completed, the input / output control unit 112 instructs the signal generation unit 113 to generate a function test signal on the execution return loss. When the function test on the execution return loss is completed, the input / output control unit 112 instructs the signal generation unit 113 to generate a function test signal related to no-call noise.

  The signal generation unit 113 generates a function test signal according to an instruction from the input / output control unit 112 (step S205). For example, the signal generation unit 113 generates a function test signal of each frequency illustrated in FIG. 6B as a function test signal related to the transmission loss frequency characteristic. Also, for example, the signal generation unit 113 generates a function test signal of each frequency illustrated in FIG. 7A as a function test signal related to the execution return loss. Also, for example, the signal generation unit 113 generates a function test signal configured with a value of 0 as a function test signal related to no-call noise.

  When the function test signal is generated by the signal generation unit 113, the input / output control unit 112 executes the function test (step S206). Specifically, the input / output control unit 112 controls the signal generation unit 113 to output a function test signal related to the level diagram to the target substrate 21 through a specific terminal of the input / output connector 13. Thus, a function test signal related to the level diagram is output to the target substrate 21. Then, the measuring unit 114 measures the level diamond from the signal obtained through the input / output connector 13. When the measurement result of each item of the level diagram is obtained, the determination unit 115 determines the quality of the measurement result for each item of the level diagram.

  Specifically, the determination unit 115 determines whether the measurement result for each item of the level diagram is a specified value or more and a recommended threshold or more, or a specified value or more and less than the recommended threshold It is determined which one is less than the specified value. Then, if there is even one item smaller than the prescribed value among the items of the level diagram, the determination unit 115 determines as NG as a result of the function test on the level diagram.

  In addition, among the items of the level diagram, the determination unit 115 determines that there is one or more items that are equal to or greater than the specified value and less than the recommended threshold for all the items, or among the items of the level diagram If all items are equal to or higher than the recommended threshold, it is determined as OK as a result of the functional test on the level diagram. The determination unit 115 outputs the determination result to the control unit 11.

  The display control unit 111 displays the result of the functional test on the level diagram based on the determination result output from the determination unit 115 (step S207). Specifically, when the output determination result indicates “NG”, the display control unit 111 displays that the function test related to the level diagram is “NG”. For example, the display control unit 111 displays the determination result in red so as to indicate that the output determination result is NG. Further, when the output determination result indicates OK, the display control unit 111 displays that the function test related to the level diagram is OK.

However, the display control unit 111 has different display modes depending on whether there is at least one item that is equal to or greater than the specified value and less than the recommended threshold for all the items and if it is greater than or equal to the recommended threshold for all the items. indicate. For example, the display control unit 111 displays the determination result in yellow when there is even one item which is equal to or more than the specified value and less than the recommended threshold value in all the items.
In addition, for example, the display control unit 111 displays the determination result in blue when all items are equal to or more than the recommended threshold.

The input / output control unit 112 determines whether all the functional tests have been completed (step S208). When all the function tests have not been completed (step S208-NO), the control unit 11 performs all the process from step S205 to step S207 described above (transmission loss frequency characteristics, execution return loss and no call) Noise).
On the other hand, when all the functional tests have been completed (YES in step S208), the input / output control unit 112 saves the result of the functional test in the storage destination selected before the functional test execution (step S209).

When an instruction to display a result is input in the process of step S201 (step S201-result display), the display control unit 111 causes the touch panel 10 to display a list of stored data of test results stored in the test result storage unit 14. It displays (step S210). For example, as shown in FIG. 8, the display control unit 111 displays the identification information of the storage destination in a different manner based on the test result stored as the storage data.
When storage data is selected via the touch panel 10, the display control unit 111 displays detailed information of the selected storage data on the touch panel 10 (step S211). For example, the display control unit 111 displays a screen as shown in FIGS.

Thereafter, the input / output control unit 112 determines whether an instruction to output stored data has been made (step S212). If the storage data output instruction has not been issued (NO in step S212), the determination apparatus 1 ends the process of FIG.
On the other hand, when a storage data output instruction is issued (step S 212 -YES), the input / output control unit 112 causes the selected storage data to be specified for another device connected via the input / output unit 15. It outputs in a form (step S213).

  The determination apparatus configured as described above includes the storage unit 20 for storing the target substrate 21, the signal generation unit 113 that generates a signal for confirming the function of the target substrate 21, and the generated signal. And a determination unit 115 which determines the quality of the target substrate 21 from the result obtained. Thereby, the quality determination can be easily performed.

  Also, as described above, conventionally, the functional test has been performed at a distant place in determining the quality of the substrate. In this case, when the distance between the location of the transmission apparatus in which the substrate is accommodated and the location of the measurement apparatus is long, the loss may increase, and an error may occur in the determination result. On the other hand, in the present invention, the housing portion 20 for housing the substrate is provided in the determination device 1, and the device for housing the substrate and the device for performing the measurement are the same housing. Therefore, the distance to perform measurement becomes short, and the loss can be reduced. As a result, quality determination of the function of the target substrate 21 can be performed more accurately.

Further, the determination apparatus 1 displays the measurement result in three different stages according to the measurement result. Thereby, the user can easily grasp which function is deteriorated in the target substrate 21.
In the display of the storage results, the data that “all the inspection results are OK and the values that satisfy all inspection results are considered to be better” and “all the inspection results are OK and some The display mode is changed for each of the data of the test result (even one value) that does not meet the level considered to be better and the data of "part or all of the test result is NG". For example, "green" is displayed with data that "all inspection results are OK and all inspection values are considered to be better", or "all inspection results are OK, In addition, the "orange" data is displayed that indicates that some test results (even one value) do not meet the standard that is considered to be better. "Some or all of the test results are NG" Display in "red", etc.

  In addition, in the conventional method, it is necessary to determine the housing position of the substrate, connect the wiring of the measuring apparatus, etc. in order to perform measurement in one functional test (for example, the execution return loss) It took (for example, 10 minutes). Moreover, in order to perform measurement in different functional tests (for example, level diamonds), it is necessary to newly change the connection of the wiring, which requires more time. On the other hand, in the determination apparatus 1 according to the present invention, in the apparatus incorporating the accommodation position for accommodating the package inside, switching of a plurality of inspection signals is performed with one button, and a plurality of inspections (level diagram , Transmission loss frequency, return loss, no-call noise), and display the inspection result. As described above, in the determination apparatus 1 according to the present invention, since a plurality of functional tests can be performed by one unit, the time required for measurement in the functional test can be reduced. For example, in the determination apparatus 1 of the present invention, the time required for all the functional tests in the embodiment is 25 seconds. As a result, it is possible to determine whether the number of target substrates 21 is good or bad.

<Modification>
In the present embodiment, as the functional test, the level measurement, the transmission loss frequency measurement, the execution return loss measurement, and the no-talk time noise measurement are described as examples, but the functional test does not have to be limited to this. For example, the function test may be any of level measurement, transmission loss frequency measurement, execution return loss measurement and no-talk time noise measurement, and may include functions other than those described above. If the function test is any of the level diagram measurement, the transmission loss frequency measurement, the execution return loss measurement and the no-talk time noise measurement, for example, the display control unit 111 measures the level diagram by the user, the transmission loss frequency measurement, the execution return loss An indication may be provided to select which of the measurement and no-talk noise measurement functional tests are to be performed.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design and the like within the scope of the present invention.
