Description

  The present invention relates to a power supply sequence measuring apparatus, a control method thereof, a program, and a recording medium, and more particularly to measurement of a power supply sequence of an image forming apparatus controller having a plurality of voltage systems.

  As a conventional multi-channel measurement apparatus, a multi-channel measurement apparatus that measures each measurement object at an optimal timing is considered in consideration of measuring a plurality of completely different measurement objects that have no temporal relationship. (For example, patent document 1). In addition, a multi-channel AD converter reading method has been proposed in which the processing time at the time of channel switching is shortened and the processing performance is improved (for example, Patent Document 2). Also, a power supply sequence detection device capable of detecting a power supply sequence abnormality between the power supply unit and the power supply unit by detecting a power supply sequence abnormality (undervoltage or overvoltage power supply abnormality) in the power supply unit. And a power supply sequence detection method has been proposed (for example, Patent Document 3). In addition, when confirming the control signal and response signal for sequence control exchanged between the control unit and the controlled unit, even if the control unit or the controlled unit is a single unit, the exchange can be confirmed. A sequence evaluation apparatus has been proposed (for example, Patent Document 4).

  Also, in an image forming apparatus having a plurality of voltage systems, each voltage system of the controller starts up in turn when the main power is turned on or when returning from the energy saving mode, but at the specified voltage level in the order and timing as designed. You have to check if it has reached. One of the means is to measure with an oscilloscope.

  When using an oscilloscope to measure a multi-channel power supply sequence, the equipment itself is large, the environment setting is difficult, and the usage is complicated. In addition, there are many oscilloscope channels with 4 channels, and measuring each voltage of equipment with a voltage system with dozens of patterns in 4 channels requires a huge amount of man-hours and is complicated. . In addition, there is a problem in that a determination result may be broken due to a determination error or a person because a human performs OK / NG determination of the measurement result. Further, the multi-channel measuring device requires an A / D converter for each of a plurality of objects to be measured, and the configuration of the device is complicated.

As a measure against this, for example, analog data to be sent to the means for A / D conversion is switched and selected, compared with stored sequence information, and OK based on predetermined voltage level / timing information of each channel. A measurement device that performs / NG determination is conceivable. The measurement apparatus further includes ON / OFF control means for main power of a controller provided in the image forming apparatus, and ON / OFF control time setting means for setting an interval time of ON / OFF control of the main power to a predetermined time. May be. In this way, it is possible to measure analog inputs sequentially by switching the main power supply ON / OFF.

In an actual power supply device, the rising slope of the power supply may vary depending on the device and may cause a malfunction. However, in the above measuring device, the power supply waveform itself such as the rising slope of the main power supply as shown in FIG. Cannot be controlled. For this reason, a margin evaluation test or the like for the rising waveform of the power supply cannot be performed only by the measuring apparatus. In addition, since only the control of the controller is targeted, a test for controlling a plurality of power supplies and evaluating a margin for the power-on time between the power supplies cannot be practiced only with the measuring apparatus. When performing such an evaluation, it is necessary to use a dedicated power supply device separately from the above-described measuring device, but the device becomes large.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments described below are preferred embodiments of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

  The configuration of the power supply sequence measuring apparatus 10 of the present embodiment is shown in FIG. The power sequence measuring apparatus 10 is roughly divided into a configuration for outputting power and a configuration for performing measurement and determination.

(Configuration to output power)
As a configuration for outputting power, the power supply sequence measuring apparatus 10 includes a power supply information storage unit 1 that stores sequence information for an output power supply, a power supply control unit 2 that reads the stored information and transmits it to the power supply output unit 3, and a power supply A power output unit 3 that actually outputs a voltage based on information from the control unit 2 is provided.

  As power supply sequence information, data of a rising waveform such as a power supply rise time and a voltage level as shown in FIG. 2 is stored in the power supply information storage unit 1 in advance. Specifically, the voltage level information at each time is converted into digital data and stored in each address of the power supply information storage unit 1 as shown in FIG.

  The operation of the power control unit 2 is controlled by a signal from the overall control unit 7, and the timing of measurement and power output is linked. Further, when the power supply control unit 2 starts outputting power, the power supply control unit 2 reads the rising waveform data stored in the power supply information storage unit 1 shown in FIG. 3 and transmits the information to the power supply output unit 3 every predetermined time. Do. At the end of output, it also performs a function of notifying the overall control unit 7 of the end timing.

  The power supply output unit 3 includes a DA converter, an amplifier, and the like, and D / A converts and amplifies the waveform information transmitted from the power supply control unit 2 and outputs a voltage. After the power is turned on, it outputs a constant voltage.

  In the above example, when the power supply control unit 2 starts power supply output, the data control unit 2 reads data 0 from the address xx00 of the power supply information storage unit 1 (usually RAM) and sets it in the DA converter of the power supply output unit 3. Subsequently, for example, data at address xx01 is read after 0.1 ms, and then data at address xx02 is read at 0.1 ms, and 1, 4,... 255 are sequentially set in the DA converter. The DA converter is set so that 0V is output for data 0 and 5V is output for data 255, and a rising voltage as shown in FIG. 2 can be realized.

(Configuration for measurement / judgment)
The power supply sequence measuring apparatus 10 measures the voltage of the measurement target 30 and transmits the information to the overall control unit 7 as a configuration for measuring and determining each sequence of the measurement target 30. The measurement result storage unit 5 that stores the sequence data, the determination information storage unit 6 that stores the comparison sequence, and the entire apparatus are controlled, and the measurement result and the determination information are compared to determine OK / NG. It has an overall control unit 7 for performing, and a determination result output unit 8 for outputting a determination result.

  As in the case of the output power sequence information (rising waveform data) described above, the measurement result is converted into digital data at the voltage level at each sampling interval, and sequentially stored at each address of each storage unit. Information for determination includes threshold values of voltage L and H at each voltage of the measurement target 30, waveform type (rising or falling), rise (falling) time information, and rising (falling) before the measurement target. Information on the power supply sequence and information on the interval between the power supply sequence and the relationship (OK if the time interval is greater than or equal to the set value, OK if less) are stored. In the example of FIG. 5, information as shown in FIG. 4 is stored in the form of predetermined digital data.

  The voltage measurement unit 4 has a plurality of measurement channels, measures each voltage value to be measured at a constant sampling interval, performs A / D conversion, and transmits the information to the overall control unit. The measured information is stored in the measurement result storage unit 5. When making the determination, the information stored in the measurement result storage unit 5 and the information stored in the determination information storage unit 6 are read out and compared by the overall control unit 7 to determine OK / NG. Is called. As shown in FIG. 5, the determination criteria are the voltage level, the rise (fall) time, and the order and interval of the rise (fall) of each sequence.

For example, when making a determination regarding sequence 2,
-Voltage level determination: whether the measured voltage value exceeds the value of VH2min-Rise time: Whether the time from when the measured voltage exceeds VL2max until it exceeds VH2min is within t2-Sequence Order / interval with 1: Determination is made based on whether or not the time from VH1min to VL2max exceeds t1_2.

  For example, assuming that measurement data is stored as shown in FIG. 6, each determination method at this time will be described below.

<Determination method of voltage level>
The stored measurement voltage values are checked in order, and if there is a measurement value that satisfies the standard, it is determined as OK. For example, when the value of VL2max is a digital conversion value and is set to 231, since the value of the measurement value stored at the address of yy6F is 232, the voltage level is OK.

<Rise (fall) time judgment method>
Regarding the time, in the above example, it is determined based on the time lag per address first place and how much the address of each measurement value is deviated. For example, regarding the rise time, assuming that the digital conversion value of VL2max is set to 25, the address 96 is shifted from when VL2max is exceeded (yy0F) to when VH2min is exceeded (yy30). . Assuming that the sampling interval is 0.1 ms and the rise time standard is 10 ms, the address shift corresponding to 10 ms is 100, so it can be determined that the rise is within the standard time.

<Order and interval with sequence 1>
Similar to the rise (fall) time, the temporal determination is performed.

  After the determination as described above is performed in the overall control unit 7, these determination results are displayed on the determination result output unit 8 using an LCD or the like.

(Measurement start timing)
In order to be able to observe all the movements of each sequence when the main power supply is started up, the measurement start timing is set so that the power supply starts up so that the power supply starts up after the measurement starts as shown in FIG. It is assumed that control is performed by the control unit 7. Specifically, the control is performed by shifting the transmission time of the measurement start signal sent from the overall control unit 7 to the voltage measurement unit 4 and the output start signal sent to the power supply control unit 2.

(Operation in this embodiment (voltage output, voltage measurement, OK / NG determination))
The operation in this embodiment is shown in the flowcharts of FIGS. FIG. 8 is a flowchart showing the operation from when the operation of the apparatus starts until the output voltage rises to a steady state. FIG. 9 is a flowchart showing the operation after a set time has elapsed since the steady state was reached.

  When starting the evaluation, first, the power source information storage unit 1 is accessed, and the power source control unit 2 performs a process of reading sequence information for output (step S1). Then, after the reading is completed, a reading completion signal is transmitted from the power supply control unit 2 to the overall control unit 7 (step S2). After the overall control unit 7 receives this signal, a measurement start signal is sent from the overall control unit 7 to the voltage measurement unit 4 (step S3), and the operation of the voltage measurement unit 4 is started. After the measurement is started, each voltage of the measurement object 30 is measured at a constant sampling interval by the voltage measurement unit 4 and the result is stored in the measurement result storage unit 5 (step S4).

  After shifting the measurement start signal by a set time, the overall control unit 7 sends an output start signal to the power supply control unit 2 (step S3). After receiving the signal, the power supply control unit 2 sends a power sequence for output. Information is started to be sent to the power supply output unit 3, D / A converted by the power supply output unit 3, and amplified to output a voltage and supply the voltage to the measurement object 30 (step S 5). In addition, after the voltage from a power supply output part rises completely, an output voltage shall be in a steady state for the set time.

  When the output voltage reaches a steady state, an output stop signal is sent from the overall control unit 7 to the power supply control unit 2 (step S6), and the output of the power supply is terminated (step S7). At the same time, a measurement end signal is transmitted from the overall control unit 7 to the voltage measurement unit 4 (step S6), the measurement is terminated, and then data storage is terminated (step S8).

  After the measurement is completed, the stored measurement results and the comparison sequence information are read from the measurement result storage unit 5 and the determination information storage unit 6, respectively, and the overall control unit 7 performs comparison to determine OK / NG (step S9). ). After the determination process is completed, the determination result is output by the determination result output unit 8 (step S10).

  According to the above embodiment, since it has a configuration for outputting power and a configuration for performing measurement / judgment, a voltage that rises with a stored slope is supplied to the measurement target, and each power sequence of the measurement target is OK. By determining / NG, it is possible to perform a margin test on the waveform of the supply voltage.

  In the power supply sequence measuring apparatus described above, the power supplied to the measurement target may be multi-channel. In this case, the power output unit 3 is configured to have a multi-channel output terminal. Regarding the sequence of the output power supply, as shown in FIG. 10, in addition to the rising slope and voltage level of each voltage, the interval at which each voltage starts rising is controlled. As for the rising waveform data, the voltage level at each time is stored in the form of digital data as in the case of the power supply sequence measuring apparatus described above, and the voltage is output by performing D / A conversion and amplification. The time interval is also controlled by this waveform data. In the example of FIG. 10, the output interval is controlled by putting 0 in the waveform data of each time of the power source 2 as shown in FIG.

  According to said structure, it becomes possible to operate the voltage of a some channel and to supply it to a measuring object.

  In the power sequence measuring apparatus described above, the waveform of the power supplied to the measurement target may be controlled even when the power is turned off. In this case, the power supply information storage unit 1 is configured to hold the falling information as shown in FIG. 12 in addition to the rising information of each voltage.

  The flow of operation of the power supply sequence measuring apparatus having the above configuration will be described with reference to the flowchart of FIG. The process from the start of the operation of the apparatus to the steady state is the same as that shown in the flowchart of FIG. 8, and S1 to S5 and steps are replaced with S11 to S15. FIG. 13 shows the operation after the steady state is reached from step S15.

  After a certain time has passed since the steady state is reached, a signal indicating completion of the steady state is sent from the overall control unit 7 to the power supply control unit 2 (step S16). After receiving the signal, the power supply control unit 2 reads the sequence information for falling stored in the power supply information storage unit 1 (step S17). Then, the read information is transmitted to the power output unit 3, and a falling voltage starts to be output (step S18).

  After the power supply finishes falling, a signal is sent from the power supply control unit 2 to the overall control unit 7 to inform the end of the fall, and then a measurement end signal is sent from the overall control unit 7 to the voltage measurement unit 4 ( Step S19). After receiving the measurement end signal, the voltage measurement and storage operation is terminated (step S20).

  Thereafter, similarly to the above-described operation, the stored measurement result and the comparison sequence information are read and compared, OK / NG determination is performed (step S21), and the determination result is output after the determination process (step S22). .

  According to the above configuration, it is possible to perform a margin evaluation test regarding a waveform at the time of power supply falling.

  In the power supply sequence measuring apparatus described above, a plurality of patterns of power supply sequence information to be supplied to the measurement target may be prepared as shown in FIG. In this case, the power supply information is sequentially read and output according to the operation flow described so far, and determination is performed. That is, first, the power information of pattern 1 is read, output, and determined, and after the operation of the number of times set in pattern 1 is completed, the power information of pattern 2 is read, output, and repeated repeatedly. It reads different patterns, outputs voltage, and measures output voltage.

  According to said structure, it becomes possible to output the sequence of a different pattern sequentially and to measure continuously.

  In the power supply sequence measurement apparatus described above, a function for connecting a removal memory may be added, and the measurement result may be stored in the removal memory. The configuration of the apparatus in this case is shown in FIG. In the power supply sequence measuring apparatus 11 of FIG. 15, the removal memory I / F 9 is mounted with a removal memory for operation. At the first activation, the removal memory I / F 9 determines whether or not the removal memory is connected, and at the time of connection, the measurement results are sequentially transferred from the overall control unit 7 and stored in the removal memory.

  The operation after the output and measurement of the power supply are completed will be described with reference to the flowchart of FIG. After the measurement is completed, the remaining memory I / F 9 checks the remaining amount of memory (step S31). When the remaining capacity of the memory to be removed is sufficient (step S32 / Yes), the following measurement is performed. On the other hand, when there is no remaining memory capacity (step S32 / No), access to the memory is stopped (step S33), and a signal is sent from the removal memory I / F 9 to the overall control unit 7 (step S34). Thereafter, the determination result display unit 8 displays that there is no remaining amount (step S35).

  Thereafter, the removable memory is replaced (step S36), and after detecting the memory installation (step S37), the capacity is confirmed (step S38). If there is no capacity (step S39 / No), the output unit displays again (step S35). If there is capacity (step S39 / Yes), the measurement operation is resumed.

  According to said structure, it becomes possible to replace | exchange a removable memory during a continuous test, and to perform a test, preserve | saving all the measurement results.

  The above-described power supply sequence measurement apparatus may be provided with a function of changing the power supply measurement sampling interval for each preset time. In this case, as shown in FIG. 17, a sampling interval for each time is designated in advance and stored. Then, when the apparatus is in operation, the information is read by the overall control unit, and based on the information, control is performed to change the interval for measuring and storing the voltage value for each time. Since the stored measurement result is a voltage value for each measurement time, the amount of stored information can be reduced and the memory usage can be saved by roughening the sampling interval at an unnecessary time.

  According to said structure, it becomes possible to perform the continuous test which adjusted the sampling interval and restrained the consumption of memory.

  The above-described embodiment is a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiment alone, and various modifications are made without departing from the gist of the present invention.
