Specific examples
To make the purpose, technical solutions and advantages of the disclosed examples clearer, the technical solutions in the disclosed examples will be clearly and completely described below with reference to the drawings in the disclosed examples.
Along with the accumulation of the travel of the motor vehicle, the power supply devices such as storage batteries and the like for providing power sources for the automobile actuator have the phenomena of aging, unstable output voltage of a generator and the like, and further the actuator works in an unstable condition.
In the prior art, an automobile electronic controller can collect the power supply voltage of power supply devices such as a storage battery in real time, adjust the power supply voltage of the power supply devices according to the collected power supply voltage, and control the power supply devices such as the storage battery to input the adjusted power supply voltage to an actuator, so that the actuator works in a stable state.
Taking a voltage control system of an automobile as an example, a storage battery of a power supply device outputs direct current, a controller adjusts the power supply voltage opening of the storage battery, namely the voltage duty ratio, through a Pulse Width Modulation (PWM) technology, so that the direct current is changed into high-level and low-level voltages, and then the controller controls the power supply device to input the high-level and low-level voltages into an actuator, so that the actuator works; in the process, the controller can acquire the voltage amplitude of the direct current output by the storage battery of the power supply device in real time, and when the voltage of the direct current output by the power supply device fluctuates, the controller can adjust the voltage opening of the direct current in real time through a PWM (pulse width modulation) technology, so that an actuator only responding to the current can work stably.
However, the method depends on whether the acquired power supply voltage can truly reflect the power supply voltage of the power supply device, when a module of the controller for acquiring the power supply voltage breaks down, the acquired power supply voltage is inaccurate, the power supply voltage of the power supply device adjusted according to the acquired power supply voltage is also inaccurate, and after the adjusted inaccurate power supply voltage is input to the actuator, the actuator works in an unstable state.
In other words, the reliability of the collected power supply voltage is not judged in the prior art, and for the problem, the present disclosure provides a voltage reliability verification method, a verification apparatus, a control device, and a storage medium, so as to judge the reliability of the collected power supply voltage.
Fig. 1 is a schematic structural diagram of a voltage control system based on the present disclosure, and as shown in fig. 1, the voltage control system includes a power supply device 10, a controller 20, and an actuator 30, where the power supply device 10, the controller 20, and the actuator 30 are electrically connected in sequence, and the controller 20 is configured to adjust a power supply voltage of the power supply device 10 and control the power supply device 10 to input the adjusted power supply voltage to the actuator 30.
In a first aspect, the present disclosure provides a voltage credibility checking method, and fig. 2 is a schematic flow chart of the voltage credibility checking method provided by the present disclosure, it should be noted that the voltage credibility checking method is applicable to the voltage control system shown in fig. 1, and an execution subject of the method is the controller 20 or an independent checking device and the like in the voltage control system shown in fig. 1. When the execution main body is an independent verification device, the verification device can receive data provided by the voltage control system in a wired or wireless, near field or remote mode and feed back the data after corresponding processing is carried out on the data.
As shown in fig. 2, the voltage reliability verification method includes:
In this step, the actuator may be an actuator that responds only to the current, that is, the actuator may be a flow rate metering unit, a hydraulic valve, or the like, as long as the current input to the actuator is the current required by the actuator, regardless of the magnitude of the supply voltage of the power supply device. The collected voltage opening value of the actuator refers to the duty ratio of the voltage input to the actuator.
And step 202, inquiring theoretical voltage of the power supply device in a preset relation comparison table according to the current value and the voltage opening value.
The relation comparison table records the comparison relation between the actuator in the normal working state and the theoretical voltage output by the power supply device under different current values and different voltage opening values.
In this step, according to the collected current value and voltage opening value, and by looking up a table, the output voltage of the power supply device corresponding to the actuator at a certain current value and a certain voltage value is obtained.
As an optional example, the relationship comparison table is obtained by a calibration method, which specifically includes the following steps:
adjusting the current and voltage opening of the actuator in a normal working state under each working condition so as to enable the actuator to be at a plurality of current values and a plurality of voltage opening values;
and acquiring the output voltage of the power supply device when the actuator has a plurality of current values and a plurality of voltage opening values, and taking the output voltage as the theoretical voltage of the power supply device to obtain the relation comparison table.
In this step, the current feedback actuator with stable working condition is selected, the current feedback actuator is adjusted to be in different current and voltage openings, the output voltage of the power supply device at the moment is recorded, the output voltage is recorded as the theoretical voltage of the power supply device, and a relation comparison table is obtained according to the theoretical voltage.
And 203, judging whether the power supply voltage measured value is credible according to a comparison result of the power supply voltage measured value and the theoretical voltage.
In this step, the measured value of the supply voltage is compared with the theoretical voltage value, and when the difference between the measured value of the supply voltage and the theoretical voltage value is large, it indicates that a large error exists in the measured value of the supply voltage collected at this time, that is, the measured value of the supply voltage is not reliable, and the supply voltage of the power supply device cannot be adjusted according to the measured value of the supply voltage. When the difference between the measured value of the power supply voltage and the theoretical voltage value is small, the reliability of the acquired measured value of the power supply voltage is high, and the controller can adjust the power supply voltage of the power supply device according to the measured value of the power supply voltage.

and 301, acquiring a current value and a voltage opening value of the actuator and a power supply voltage measured value of the power supply device in real time.
And 302, inquiring the theoretical voltage of the power supply device in a preset relation comparison table according to the current value and the voltage opening value.
The relation comparison table records the comparison relation between the actuator in the normal working state and the theoretical voltage output by the power supply device under different current values and different voltage opening values.
And step 304, judging whether the deviation is larger than a preset threshold value.
If the deviation is greater than the preset threshold, go to step 305; if the deviation is not greater than the predetermined threshold, go to step 306.
Step 301 and step 302 in this example are similar to the implementation manners of step 201 and step 202 in the foregoing example, and are not described herein again.
In contrast to the previous example, the present example further presents a method how to determine whether the collected supply voltage is authentic, i.e. by calculating the deviation of the supply voltage measurement from the theoretical voltage; judging whether the deviation is greater than a preset threshold value or not; if the deviation is larger than a preset threshold value, determining that the power supply voltage measured value is not credible; otherwise, the system can be trusted.
Specifically, the preset threshold value in this step may be set according to experience of those skilled in the art, and the present disclosure does not limit this. Optionally, after the power supply voltage measurement value is determined to be unreliable, collected unreliable information of the power supply voltage can be reported in modes of voice broadcasting or subtitles, so that a worker can be conveniently reminded of timely carrying out fault detection on a module for collecting the power supply voltage.
According to the voltage credibility verification method provided by the disclosed example, the current value and the voltage opening value of the actuator and the power supply voltage measured value of the power supply device are collected in real time; inquiring the theoretical voltage of the power supply device in a preset relation comparison table according to the current value and the voltage opening value, wherein the relation comparison table records the comparison relation between the actuator in the normal working state and the theoretical voltage output by the power supply device under different current values and different voltage opening values; calculating the deviation of the measured value of the power supply voltage and the theoretical voltage; judging whether the deviation is greater than a preset threshold value or not; if the deviation is larger than the preset threshold value, determining that the power supply voltage measured value is not credible; if the deviation is not greater than the preset threshold value, the power supply voltage measured value is determined to be credible, the credibility of the collected power supply voltage measured value is judged, the accuracy of adjusting the power supply voltage input to the actuator according to the collected power supply voltage measured value is further improved, and the working stability of the actuator is improved.
With reference to the foregoing examples, fig. 4 is a schematic flowchart of another voltage reliability verification method provided by the present disclosure, and as shown in fig. 4, the voltage reliability verification method includes:

And 403, calculating the deviation between the measured value of the power supply voltage and the theoretical voltage.
And step 404, judging whether the deviation is larger than a preset threshold value.
If the deviation is greater than the preset threshold, executing step 405 and step 407; if the deviation is not greater than the preset threshold, go to step 406.
Step 405, determining that the supply voltage measurement is not authentic.
The steps 401 and 406 in this example are similar to the implementation manners of the steps 301 and 306 in the foregoing example, and are not described herein again.
Unlike the previous example, this example further defines how to adjust the supply voltage, that is, correct the supply voltage of the power supply device according to the theoretical voltage, and control the power supply device to input the corrected supply voltage to the actuator when it is determined that the acquired supply voltage is not authentic.
Specifically, when the acquired power supply voltage is judged to be unreliable, an error occurs if the controller adjusts the power supply voltage of the power supply device according to the acquired power supply voltage, the power supply voltage with the adjusted error is input into the actuator, and the actuator works in an unstable state; therefore, the present example is that the theoretical voltage adjusts the supply voltage of the power supply device when it is determined that the collected supply voltage is not authentic.
As an alternative example, the modifying the supply voltage of the supply device according to the theoretical voltage includes:
and adjusting the voltage opening of the power supply voltage of the power supply device according to the theoretical voltage.
Specifically, when the acquired measured value of the power supply voltage is not credible, the power supply voltage of the power supply device is corrected according to the theoretical voltage, and when the acquired measured value of the power supply voltage is credible, the power supply voltage of the power supply device is corrected according to the acquired measured value of the power supply voltage. When the correction is performed, the voltage input to the actuator can ensure that the current of the actuator is just the current required by the stable operation of the actuator by changing the opening degree of the power supply voltage, namely the voltage duty ratio.
According to the voltage credibility verification method provided by the example of the disclosure, after the measured value of the power supply voltage is determined to be untrustworthy, the power supply voltage of the power supply device is corrected according to the theoretical voltage, and the power supply device is controlled to input the corrected power supply voltage to the actuator, so that the problem that the power supply voltage cannot be effectively adjusted due to the fact that the acquired measured value of the power supply voltage is untrustworthy is avoided.
