Fig. 3 shows a flowchart of a product model verification provided by an embodiment of the present invention.
According to an embodiment of the present invention, as shown in fig. 3, the determining whether a preset voltage threshold requirement is met according to the second voltage information is specifically:

It should be noted that, the present invention also checks whether the current first application program is adapted to the electrical characteristics of the electronic circuit through the second voltage information, so as to determine whether the product model is selected correctly; that is, when the second voltage information reaches the preset voltage threshold, the product model is selected correctly. Firstly, judging whether the second voltage information is in a preset stable state or not; the preset stable state indicates whether the floating condition of the second voltage information meets the requirement of the first application program operation. When the second voltage information is in a stable state, calculating a difference value between the second voltage information and a preset voltage threshold value to obtain first voltage difference value information; the preset voltage threshold is a reference standard of the second voltage information when the first application program runs. For the preset voltage threshold, a corresponding first difference range is also set, and in practical application, the first difference range is usually set as a percentage floating value of a reference standard, for example, when the voltage threshold of 1V is used as the reference standard, the floating value of 10% is calculated, and the floating difference is 0.1V, that is, the first difference range is-0.1V to 0.1V. When the first voltage difference information is within the first difference range, the second voltage information obtained by the measurement electronic circuit is in accordance with the voltage threshold requirement set by the first application program, that is, the application software is matched with the electronic hardware, and the model selection can be determined to be correct. When the first voltage difference information exceeds the first difference range, the second voltage information obtained by the measurement electronic circuit does not meet the voltage threshold requirement set by the first application program, namely, the application software is not matched with the electronic hardware, the model selection error can be determined, the user needs to jump to the starting program again, and the selection operation of the first application program, namely, the model selection operation, is executed. The invention improves the accuracy of model selection in a verification mode.
According to an embodiment of the present invention, the determining whether the second voltage information is in a preset stable state specifically includes:
acquiring the second voltage information in a preset time period;
extracting at least two pieces of nearest second voltage information and calculating average voltage to obtain voltage average information;
calculating the difference value between the extracted second voltage information and the voltage average value information to obtain second voltage difference value information;
judging whether the second voltage difference information is lower than a preset difference threshold value or not;
if so, the state is in a stable state.
It should be noted that, with a preset sampling period, the second voltage information is continuously collected through the analog-to-digital converter. At least two newly acquired second voltage information are extracted for calculating an average voltage. Calculating the difference value of the extracted second voltage information and the voltage average value one by one, and recording the difference value as second voltage difference value information; if each second voltage difference value information is lower than a preset difference value threshold value, the second voltage is in a stable state; if any one of the second voltage difference information is higher than the difference threshold value, the state is in an unstable state. When the first application program is operated, the voltage for supplying power to the circuit where the first resistor is positioned is usually the voltage for supplying power to the processing of the electronic product; if the second voltage information is in a stable state, the second voltage information indicates that the power supply voltage is in a stable state. That is, when the second voltage information is in a stable state, the stability of the power supply voltage meets the operation requirement of the processor.
According to an embodiment of the present invention, further comprising:
the first digital rheostat is used for adjusting the first resistance information;
and adjusting the resistance information of the first digital rheostat through a preset communication instruction to switch the product model.
It should be noted that the first resistor may be formed by one or more resistors connected in series or in parallel, where at least one resistor is a first digital varistor; among them, a digital varistor is also called a digital programmable resistor, which is a resistor capable of digitally adjusting a resistance value. By means of the first digital varistor, it is possible to realize a software-regulated first resistance information of the first resistor. The processor is communicatively coupled to the first digital varistor via a predetermined communication protocol including, but not limited to, reading a resistance value of the first digital varistor via a predetermined read command in real-time communication, and adjusting the resistance value of the first digital varistor via a predetermined modify command. And adjusting the first resistance information through the first digital rheostat, so that the function of modifying the product model through software is realized.
According to an embodiment of the present invention, further comprising:
acquiring first abnormal information in the running process of a first application program;
judging whether the first abnormal information is a preset abnormal code or not;
if yes, entering a self-checking program, and processing an abnormal state by switching the product model.
When the processor runs the first application program, when an abnormal state occurs, the processor records the abnormal program and has a unique abnormal code corresponding to the abnormal program. For example, the screen communication abnormality corresponding to the abnormality code is 0x0011, and the battery information acquisition abnormality corresponding to the abnormality code is 0x0023. The first abnormal information refers to the condition that the software driver is abnormal in communication with the hardware accessory, and a preset abnormal code is reported. For example, when the communication mode of the first application software to the screen is IIC and the communication mode of the screen hardware is SPI, the first anomaly information recorded by the first application software belongs to a preset anomaly code. When the first anomaly information is a preset anomaly code, the possibility of selection errors of the product model is indicated, and a self-checking program is needed. The self-checking program is the same as the process of detecting the product model by starting.
It is worth mentioning that the method further comprises:
acquiring a first remote instruction;
and adjusting the resistance information of the first digital rheostat according to the first remote instruction so as to switch the product model.
It should be noted that, when the serial products include the remote communication function, the remote switching of the product model may be implemented by a network, bluetooth, or the like. After receiving the first remote instruction, checking and analyzing the requirement of the remote instruction for switching the model of the product, and reversely inquiring the first resistance information of the corresponding first resistor according to the coding table when the model switching information is confirmed to be correct, and then calculating the resistance information of the digital rheostat according to the combination condition of the first resistance information; wherein the combination is typically at least one resistor of fixed value in series with at least one digital varistor. Finally, the resistance value of the digital rheostat is adjusted through a preset communication instruction, and the purpose of remotely switching the product model is finally achieved. In practical application, certain series products are divided into high-configuration, medium-configuration and low-configuration versions according to different software functions, but hardware accessories are always the same, when a user has the function configuration upgrading requirement, replacement or factory staff to upgrade on site is not needed, and the switching of product types is directly realized in a remote mode, so that the labor cost is saved, and the user experience is also improved.
It is worth mentioning that the method further comprises:
searching a preset coding table according to the first resistance information, and when no corresponding coding information exists;
acquiring resistance information of a first digital rheostat;
the resistance value is adjusted upwards or downwards according to the resistance value information;
if the obtained first resistance information is found, and the corresponding code cannot be found from the code table, it indicates that there is a setup error in the production process. In order not to influence the use of a user, the first resistance information is adjusted by adjusting the resistance information of the first digital rheostat upwards or downwards while recording the mark information, so that the model is searched in an adaptive mode. Because the product has model verification in operation, and when the hardware fittings are not matched, the self-checking mode is also entered, and model inquiry and switching are carried out according to the mark information.

When the first voltage difference information exceeds the first difference range, the second voltage information obtained by the measurement electronic circuit does not meet the voltage threshold requirement set by the first application program, namely, the application software is not matched with the electronic hardware, the model selection error can be determined, the user needs to jump to the starting program again, and the selection operation of the first application program, namely, the model selection operation, is executed. The invention improves the accuracy of model selection in a verification mode.
According to an embodiment of the present invention, the determining whether the second voltage information is in a preset stable state specifically includes:
acquiring the second voltage information in a preset time period;
extracting at least two pieces of nearest second voltage information and calculating average voltage to obtain voltage average information;
calculating the difference value between the extracted second voltage information and the voltage average value information to obtain second voltage difference value information;
judging whether the second voltage difference information is lower than a preset difference threshold value or not;
if so, the state is in a stable state.
It should be noted that, with a preset sampling period, the second voltage information is continuously collected through the analog-to-digital converter. At least two newly acquired second voltage information are extracted for calculating an average voltage. Calculating the difference value of the extracted second voltage information and the voltage average value one by one, and recording the difference value as second voltage difference value information; if each second voltage difference value information is lower than a preset difference value threshold value, the second voltage is in a stable state; if any one of the second voltage difference information is higher than the difference threshold value, the state is in an unstable state. When the first application program is operated, the voltage for supplying power to the circuit where the first resistor is positioned is usually the voltage for supplying power to the processing of the electronic product; if the second voltage information is in a stable state, the second voltage information indicates that the power supply voltage is in a stable state. That is, when the second voltage information is in a stable state, the stability of the power supply voltage meets the operation requirement of the processor.
According to an embodiment of the present invention, further comprising:
the first digital rheostat is used for adjusting the first resistance information;
and adjusting the resistance information of the first digital rheostat through a preset communication instruction to switch the product model.
It should be noted that the first resistor may be formed by one or more resistors connected in series or in parallel, where at least one resistor is a first digital varistor; among them, a digital varistor is also called a digital programmable resistor, which is a resistor capable of digitally adjusting a resistance value. By means of the first digital varistor, it is possible to realize a software-regulated first resistance information of the first resistor. The processor is communicatively coupled to the first digital varistor via a predetermined communication protocol including, but not limited to, reading a resistance value of the first digital varistor via a predetermined read command in real-time communication, and adjusting the resistance value of the first digital varistor via a predetermined modify command. And adjusting the first resistance information through the first digital rheostat, so that the function of modifying the product model through software is realized.
According to an embodiment of the present invention, further comprising:
acquiring first abnormal information in the running process of a first application program;
judging whether the first abnormal information is a preset abnormal code or not;
if yes, entering a self-checking program, and processing an abnormal state by switching the product model.
When the processor runs the first application program, when an abnormal state occurs, the processor records the abnormal program and has a unique abnormal code corresponding to the abnormal program. For example, the screen communication abnormality corresponding to the abnormality code is 0x0011, and the battery information acquisition abnormality corresponding to the abnormality code is 0x0023. The first abnormal information refers to the condition that the software driver is abnormal in communication with the hardware accessory, and a preset abnormal code is reported. For example, when the communication mode of the first application software to the screen is IIC and the communication mode of the screen hardware is SPI, the first anomaly information recorded by the first application software belongs to a preset anomaly code. When the first anomaly information is a preset anomaly code, the possibility of selection errors of the product model is indicated, and a self-checking program is needed. The self-checking program is the same as the process of detecting the product model by starting.
It is worth mentioning that the method further comprises:
acquiring a first remote instruction;
and adjusting the resistance information of the first digital rheostat according to the first remote instruction so as to switch the product model.
It should be noted that, when the serial products include the remote communication function, the remote switching of the product model may be implemented by a network, bluetooth, or the like. After receiving the first remote instruction, checking and analyzing the requirement of the remote instruction for switching the model of the product, and reversely inquiring the first resistance information of the corresponding first resistor according to the coding table when the model switching information is confirmed to be correct, and then calculating the resistance information of the digital rheostat according to the combination condition of the first resistance information; wherein the combination is typically at least one resistor of fixed value in series with at least one digital varistor. Finally, the resistance value of the digital rheostat is adjusted through a preset communication instruction, and the purpose of remotely switching the product model is finally achieved. In practical application, certain series products are divided into high-configuration, medium-configuration and low-configuration versions according to different software functions, but hardware accessories are always the same, when a user has the function configuration upgrading requirement, replacement or factory staff to upgrade on site is not needed, and the switching of product types is directly realized in a remote mode, so that the labor cost is saved, and the user experience is also improved.
It is worth mentioning that the method further comprises:
searching a preset coding table according to the first resistance information, and when no corresponding coding information exists;
acquiring resistance information of a first digital rheostat;
the resistance value is adjusted upwards or downwards according to the resistance value information;
if the obtained first resistance information is found, and the corresponding code cannot be found from the code table, it indicates that there is a setup error in the production process. In order not to influence the use of a user, the first resistance information is adjusted by adjusting the resistance information of the first digital rheostat upwards or downwards while recording the mark information, so that the model is searched in an adaptive mode. Because the product has model verification in operation, and when the hardware fittings are not matched, the self-checking mode is also entered, and model inquiry and switching are carried out according to the mark information.
