Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating an operating voltage Processing method according to an exemplary embodiment, and as shown in fig. 1, the operating voltage Processing method may be used in a microprocessor such as a Processing module or an embedded controller on a computing board, which may be a computing chip and/or an image Processing chip, but is not limited to a computing chip and/or an image Processing chip (GPU), and the like, wherein the computing chip includes but is not limited to an Application Specific Integrated Circuit (ASIC) chip. As shown in fig. 1, the disclosed method includes the steps of:

in step S11, the operating voltage of the load on the computing board is collected.

Here, the load on the computing board may be part or all of the load of the computing board, for example, the load of each chip on the computing board, the load of part of an integrated circuit or the load of some components, and so on. The working voltage refers to a voltage required by the load of the whole force computing board when working, such as 18V or 20V.

The processing module of this embodiment can be installed on the board of doing all can, as shown in fig. 4, can reduce the use of connecting wire like this, has simplified the structure of board of doing all can promptly, also conveniently gathers the operating voltage of load on the board of doing all can.

In step S12, it is determined whether the minimum operating voltage of the load in the current period exceeds a stored voltage, wherein the stored voltage is: a minimum operating voltage of the load over a historical period of time.

The current time period may be a preset time period in the current load operation process. For example, in the load working process, the processing module acquires the working voltage of the load on the computing board, and determines the preset time length T to divide the time. The current time period is: the current time is within a time period equal to T.

The T may be 5, 10, 15, or 30 minutes, etc. in duration.

For example, whether the minimum operating voltage in the current 10 minute period exceeds the storage voltage, or whether the minimum operating voltage in the current 30 minute period exceeds the storage voltage, etc. in this embodiment, the preset period is not specifically limited, and may be, for example, 20 minutes or 40 minutes, etc.

Optionally, the processing module of this embodiment periodically acquires the working voltage of the load on the computing board within a preset time period. Illustratively, the processing module collects the operating voltage of the load on the computing board for half an hour every 10 minutes, and determines whether the minimum operating voltage exceeds the stored voltage for the current half hour, or the processing module begins collecting the operating voltage of the load on the computing board for half an hour according to a set point in time, such as the processing module collecting the operating voltage of the load on the computing board for half an hour 10 minutes at 13, and determines whether the minimum operating voltage exceeds the stored voltage for the current half hour.

Here, for the force calculation board just put into use, the minimum operating voltage in the history period at this time may be 0V; for the force calculation board put into use for a period of time, the minimum operating voltage of the historical period at this time may be the minimum operating voltage of the force calculation board in the previous period.

Because the voltage value that processing module can gather may be less than the actual operating voltage of load, so can carry out the step-down processing to the operating voltage of load earlier when processing module gathers load operating voltage for the voltage value after the step-down accords with the voltage acquisition requirement of processing module. It should be understood that, in this embodiment, the setting of the minimum operating voltage in the history period is not particularly limited, and may also be a voltage of the over-frequency operation that is pre-manufactured in the factory, for example, the voltage of the over-frequency operation may be an operating voltage of an over-frequency state written according to statistical data or laboratory data.

In step S13, when the minimum operating voltage in the current period exceeds the stored voltage, the minimum operating voltage in the current period is updated to the stored voltage, where the stored voltage is at least used to determine whether the load on the computing board has operated in the over-frequency state.

Illustratively, during the load operation, the processing module collects the operating voltage of the load on the computing board and determines whether the minimum operating voltage in the current time period exceeds the storage voltage, for example, the minimum operating voltage in the current 30-minute time period is 4V, and the storage voltage is 3V, so that the minimum operating voltage 4V in the current time period exceeds the storage voltage 3V, and the minimum operating voltage 4V in the current time period is updated to the storage voltage, that is, the storage voltage becomes 4V.

Optionally, the storage voltage is maintained when the minimum operating voltage in the current period does not exceed the storage voltage. Illustratively, the processing module collects the working voltage of the load on the computing board, and determines that the minimum working voltage in the current 10-minute period is 2V and the storage voltage is 3V, so that the minimum working voltage 2V in the current period does not exceed the storage voltage 3V, and the storage voltage is maintained, i.e. the storage voltage is still 3V.

The stored voltage may be used at least to determine whether the load on the force plate has been operated in an overclocking state.

In the related art, when the over-frequency judgment is carried out after the fault is sold, the log is captured by the control panel, the judgment is carried out manually, the efficiency is low, and the judgment cannot be carried out by 100%. However, in meeting the work requirements, the force board may often overclock in order to obtain more data, resources, benefits, etc. However, the log is easily modified or deleted, so that it cannot be accurately determined whether the force board is over-frequency.

Therefore, the embodiment determines whether the load on the computation force board works in the over-frequency state or not by storing the voltage, and the identification speed is high and the accuracy is high.

Optionally, the processing module of this embodiment may directly determine whether the load on the computation force board has operated in the over-frequency state by storing the voltage. Specifically, when the storage voltage is greater than the minimum over-frequency voltage, it is determined that the load on the computation board has operated in an over-frequency state; when the storage voltage is not greater than the minimum over-frequency voltage, it is determined that the load on the computing board does not work in the over-frequency state, for example, the current storage voltage is 4V, the minimum over-frequency voltage is 3.5V, it is determined that the load on the computing board does work in the over-frequency state, or the current storage voltage is 3V, the minimum over-frequency voltage is 3.5V, it is determined that the load on the computing board does not work in the over-frequency state.

In other embodiments, the original voltage of the storage voltage may be 0V, so that the minimum operating voltage of the force plate just put into use during the first period can be successfully recorded as the storage voltage.

Optionally, in this embodiment, the upper computer may obtain the storage voltage of the processing module, and then the upper computer determines whether the load on the computation force board has worked in the over-frequency state through the storage voltage.

As shown in fig. 4, the upper computer is connected to a signal output pin of the processing module, the upper computer obtains a current storage voltage of the processing module, and when the storage voltage is greater than the minimum over-frequency voltage, it is determined that the load on the computation board has been operated in the over-frequency state. And when the storage voltage is not greater than the minimum overclocking voltage, determining that the load on the computing board does not work in an overclocking state. For example, the current storage voltage acquired by the upper computer is a first voltage, and the minimum overclocking voltage stored inside the upper computer is a second voltage greater than the first voltage, so that it is determined that the load on the computation board has operated in an overclocking state. The minimum overclocking voltage is the minimum voltage which is stored in the upper computer and is loaded on the computing board to work in an overclocking state.

In some embodiments, after it is determined that the load on the computation force board works in the overclocking state, information such as storage voltage, overclocking time period or time in the current overclocking state is recorded, so that the failed computation force board is conveniently judged, and the failure reason of the computation force board is quickly determined.

In other embodiments, whether the load on the computation board is in a normal working state or whether a fault occurs or the like can be further determined through the stored voltage of the embodiment.

In the embodiment, aiming at the characteristic that the overload needs to be pressurized, the working voltage of the load is obtained in real time through the processing module on the force calculation board, and whether the load on the force calculation board works in the overload state is determined by comparing the minimum working voltage of the load in the current time period with the stored voltage, namely, the method is solidified on the force calculation board, so long as the user carries out pressurization and overload, the user can be identified and recorded by the processing module on the force calculation board, the identification speed is high, the accuracy is high, meanwhile, the after-sale department can conveniently judge the failed force calculation board, and the fault reason of the force calculation board is quickly determined.

In one embodiment, all the working voltages collected at the preset frequency in the current time period are recorded, and when the minimum working voltage in the current time period needs to be determined, all the recorded working voltages are traversed to determine the minimum working voltage.

In another embodiment, as shown in fig. 2, the operating voltage processing method may further include:

in step S21, the current operating voltage of the load collected at a preset frequency is compared with the recorded voltage during the current period.

Here, the recording voltage may be a voltage pre-manufactured in the factory, and is used to determine a minimum operating voltage of the load in the current period, for example, the recording voltage is 5V, or may be an operating voltage for writing statistical data or laboratory data, and the like.

For example, in the current half-hour period, the processing module collects the current working voltage of the load at 20000Hz and compares the working voltage of the load collected each time with the recording voltage, for example, the recording voltage may be 5V, and the processing module compares the working voltage collected each time with 5V.

The embodiment does not specifically limit the preset frequency, preferably, the preset frequency is greater than 10000Hz, so that voltage collection in the over-frequency state can not be missed due to too few collection times, the working state of the load on the real-time monitoring computing force board is guaranteed, and the over-frequency identification accuracy is improved.

In step S22, when the current operating voltage is less than the recording voltage, the current operating voltage is updated to the recording voltage.

In step S23, when the current operating voltage is greater than the recording voltage, the current recording voltage is maintained.

In step S24, at the end of the present period, the recording voltage is determined as the minimum operating voltage within the present period.

Specifically, referring to fig. 3, the recording voltage is a, the current operating voltage is B, and the storage voltage is C. The processing module collects the working voltage of the load on the force calculation plate at a preset frequency, compares the collected current working voltage B of the load with the recorded voltage A in the current half-hour period, and updates the current working voltage B into the recorded voltage A if the current working voltage B is smaller than the recorded voltage A.

After the judgment of the current working voltage and the recording voltage is completed once, whether the collection of the working voltage of the current round reaches a preset time length is judged, for example, half an hour.

And if the collection of the working voltage of the current round reaches the preset duration, determining the current recording voltage A as the minimum working voltage in the current time period.

And if the collection of the working voltage of the current round does not reach the preset duration, continuously collecting the current working voltage B, and continuously comparing the current working voltage B with the recorded voltage A until the current time period is finished.

Further, the processing module determines whether the minimum working voltage of the load in the current period exceeds the storage voltage C, updates the minimum working voltage in the current period to the storage voltage C when the minimum working voltage in the current period exceeds the storage voltage C, maintains the current storage voltage C if the minimum working voltage in the current period does not exceed the storage voltage C, continues to collect the current working voltage B in the next period, and judges whether the minimum working voltage in the next period exceeds the storage voltage C. Finally, whether the load works in the overclocking state can be determined according to the storage voltage C.

By adopting the mode, only one recording voltage needs to be stored in one time period, so that all the collected working voltages are equivalently stored, and the consumption of storage resources is reduced; and when a latest working voltage is collected, the latest working voltage is compared with the recording voltage, so that the recording voltage can be directly determined as the minimum working voltage of the current time period when the current time period is finished, and the method has the characteristic of high minimum working voltage determination speed.

In some embodiments, the operating voltage processing method may further include: and outputting a power-off signal when the minimum working voltage in the current period exceeds the storage voltage. The power-off signal is used for controlling the power supply module to stop supplying power to the load.

Referring to fig. 4, the processing module is also connected to a power supply module for supplying power to the load on the force computation board. When the processing module determines that the minimum working voltage in the current time period exceeds the storage voltage, the processing module can determine that the load works in the overclocking state, and in order to prevent the computing board from overclocking, the processing module can output a power-off signal to control the power supply module to stop supplying power to the load.

For example, the minimum working voltage in the current time period is 4.5V, the storage voltage is 4V, the processing module outputs a power-off signal and controls the power supply module to stop supplying power to the load, so that the phenomenon of the power board working at an excessive frequency can be reduced, namely, the power board can be forcibly powered off after the random time duration of the excessive frequency is achieved, and the damage degree of the power board caused by the excessive frequency working of the power board is reduced.

Optionally, the processing module of this embodiment may further store the minimum over-frequency voltage, and when the current stored voltage is greater than the minimum over-frequency voltage, it is determined that the load on the computation board has operated in the over-frequency state, and a power-off signal is output to control the power supply module to stop supplying power to the load.

For example, if the current storage voltage is 4.5V and the minimum over-frequency voltage is 3.5V, the processing module determines that the load on the computation board has operated in an over-frequency state, and outputs a power-off signal to control the power supply module to stop supplying power to the load, thereby reducing the time length of the over-frequency operation of the computation board and reducing the damage degree of the computation board caused by the over-frequency operation of the computation board.

In some embodiments, the power down signal may include: and the group of signals controls the power supply to sequentially cut off the power supply of different loads on the force calculation board according to the power-off protection time sequence of the force calculation board, so that the damage of software and hardware caused by cutting off all the power supply of the force calculation board at one time is reduced.

Optionally, as shown in fig. 4, the upper computer is connected to the processing module, and may also be connected to the power supply module. Therefore, the current storage voltage of the processing module can be obtained through the upper computer, when the storage voltage is larger than the minimum overclocking voltage, the fact that the load on the force calculation board works in an overclocking state is determined, and a power-off signal is output to the power supply module to control the power supply module to stop supplying power to the load, so that the phenomenon that the force calculation board works in an overclocking mode is reduced.

Of course, the storage voltage can be only used for the fault use of the subsequent positioning force calculation plate, and the upper computer does not need to output a power-off signal when the storage voltage is larger than the over-frequency working voltage. The output power-off signal under the condition is reduced, so that the user satisfaction caused by the stopping of the computing board or the forced stopping of the work of the computing board is caused.

In some embodiments, the processing module may have a first mode and a second mode.

Specifically, in the first mode, the power-off signal is generated when the processing module determines that the minimum working voltage in the current period exceeds the storage voltage. In a second mode, the processing module does not generate the power-off signal when determining that the minimum working voltage in the current period exceeds the storage voltage.

Thus, the use mode of the processing module can be selected according to actual requirements. For example, a sudden power failure may cause data loss or the like, which causes unnecessary loss, and at this time, the processing module only needs to record the storage voltage by selecting the second mode based on the user input.

If the force calculation board has a fault, data can be provided for maintenance personnel; for example, if the computing board is used normally and stably, the computing board can continue to work before power failure after power failure in order not to damage equipment or prevent data loss and the like of the computing board after power failure, so that the working mode of the processing module is set to the second mode, and a power failure signal is generated when the minimum working voltage in the current time period exceeds the storage voltage to protect the computing board, prolong the service life of the computing board, and reduce software and hardware faults of the computing board.

In one embodiment, as shown in fig. 4, at least one pin of the processing module is connected to a power bus of the load on the computing board; the power supply bus supplies power to the load, and the power supply voltage of the power supply bus is the working voltage of the load.

For example, a signal receiving pin of the processing module is connected with a power supply bus of a load on the computing board and used for collecting power supply voltage of the power supply bus, a signal output pin of the processing module is also connected with the power supply bus of the load on the computing board, and when the processing module generates a power-off signal, the connection between the power supply bus and the load can be controlled to be disconnected, and power supply to the load is stopped. Therefore, the processing module is not required to be connected with the power supply module, voltage collection and power supply control are facilitated, and the structure of the whole force computing board is simplified due to the fact that the use of connecting wires is reduced.

In some embodiments, the processing module may include: ADC, programmable unit and memory.

Illustratively, the analog pin of the ADC is connected to the supply bus; and an output pin of the programmable unit is connected with a switch on the power supply bus and used for disconnecting or connecting the connection between the load and the power supply bus. And a data receiving pin of the programmable unit is connected with the memory and is used for acquiring the storage voltage recorded by the memory.

In another exemplary embodiment, the ADC is configured to convert an analog signal of the obtained working voltage of the load into a digital signal, and output the digital signal to the programmable unit, the memory is configured to be used by the processing module to record a storage voltage, and the programmable unit may obtain the storage voltage from the memory and compare the storage voltage with the minimum working voltage. Here, the memory may be a Flash memory, or may be a data storage device such as a ROM or a Random Access Memory (RAM).

Illustratively, referring to fig. 6, the processing module may be a PIC chip including an ADC, a programmable unit, and a memory. For example, the analog pin RC2 of the PIC chip is connected to the power supply bus for collecting the voltage of the power supply bus, and the signal output pin RA2 of the PIC chip is connected to the switch on the power supply bus for controlling the switch on or off of the power supply bus, so as to control the power supply bus to supply power to the load. The programmable unit in the PIC chip determines whether the minimum working voltage of the load in the current period exceeds the storage voltage in the memory, and when the minimum working voltage in the current period exceeds the storage voltage, the minimum working voltage in the current period is updated to the storage voltage, so that whether the load on the computation board works in an over-frequency state can be determined according to the storage voltage.

The above embodiments, in hardware: the voltage of a power supply bus is divided and then supplied to the simulation pin of the processing module, the continuous acquisition and interruption function of the simulation pin of the processing module can ensure that the processing module is used for acquiring the working voltage of a load at a preset frequency, the minimum working voltage in the current time period is compared with the stored voltage stored in the internal storage, when the minimum working voltage exceeds the stored voltage, the minimum working voltage is updated to the stored voltage, namely, the stored voltage is updated to the memory for storage, the stored voltage is recorded in the internal storage, whether the load is overfrequency is determined according to the stored voltage, and therefore, the overfrequency identification structure and the process are simplified, the overfrequency identification speed is high, the accuracy is high, the overfrequency of a force calculation board is avoided, and normal work is ensured.

Meanwhile, the storage voltage in the internal memory is recorded and can be checked after sale, for example, after sale personnel can obtain the voltage value stored in the internal memory of the processing module from the force calculation board through a special jig and compare the voltage value with the minimum over-frequency voltage, and then whether the force calculation board uses special firmware over-frequency can be judged.

In one embodiment, a voltage division circuit is arranged between the processing module and the power supply bus; the voltage division circuit is used for dividing the power supply voltage of the power supply bus and then inputting the divided voltage to the processing module.

Because the normal working voltage of the load on the computing board is between 18V and 20V, and the processing module cannot directly acquire such a high voltage value, the voltage dividing circuit is utilized in the embodiment to reduce the actual working voltage according to the voltage dividing ratio, for example, the working voltage acquired by the processing module can be 3V or less than 3V, and the like, so that the acquisition requirement of the processing module is met; meanwhile, the voltage division circuit can also be used as a protection circuit to prevent the impact of high voltage on the processing module.

Alternatively, referring to fig. 5, the voltage dividing circuit of the present embodiment may include: a first resistor R29, a second resistor R32, a third resistor R28 and a filter unit 20.
