Description

Technical Field

[0001] The present invention relates to the field of electric energy meters, and more specifically, to a method, a system, and a storage medium for suppressing impulse groups of electric energy meters and terminals. Background Art

[0002] During the design process of the three-phase electric energy meter hardware circuit, the designed product needs to successfully pass the impulse group experiment. Problems at the circuit design level often cause SPI communication errors between the system MCU and the metering chip during the impulse group experiment, which in turn triggers the MCU to perform a reset operation on the metering chip.

[0003] Regarding this problem, there are currently various solutions. One solution is to change the communication method to low-speed serial communication to solve the communication problem between the MCU and the metering chip. Although this method successfully overcomes the problem of communication failure in the impulse group experiment, compared with SPI interface communication, the speed of serial communication is significantly reduced, and it is difficult to meet the actual requirements in scenarios with high real-time requirements.

[0004] Pass the impulse group experiment. Problems at the circuit design level often cause SPI communication errors between the system MCU and the metering chip during the impulse group experiment, which in turn triggers the MCU to perform a reset operation on the metering chip

[0024] Figure 1 The flowchart of a method for suppressing impulse groups of an electric energy meter and a terminal is shown.

[0025] As Figure 1 shown, in the first aspect of the present invention, a method for suppressing impulse groups of an electric energy meter and a terminal is disclosed, and the method includes: S102, obtaining first voltage information; S104, according to the first voltage information and a preset voltage reference value, obtaining first deviation information according to a preset deviation integration algorithm; S106, according to the first deviation information, obtaining first resistance adjustment amount information according to a preset adjustment amount algorithm; S108, obtaining first resistance information and second resistance information; S110, according to the magnitude relationship between the first resistance adjustment amount information, the first resistance information and the second resistance information, updating the first resistance information or the second resistance information.

[0026] It should be noted that the first voltage information is the voltage value on the communication line; the first deviation information is the deviation value calculated according to the deviation integral value obtained by the set deviation integral algorithm; the first resistance adjustment amount information is the adjustment amount for adjusting the grounding resistance value obtained by the set adjustment amount algorithm; the first resistance information is the resistance value of the first grounding resistance between the neutral wire trace and the ground wire trace on one side in the power metering circuit; the second resistance information is the resistance value of the second grounding resistance between the neutral wire trace and the ground wire trace on the side opposite to the first grounding resistance in the power metering circuit.

[0027] In this embodiment, a grounding resistance with an adjustable resistance value is provided on the neutral wire traces on both the left and right sides of the power metering circuit. By analyzing the voltage interference situation on the communication signal line in real time and through real-time feedback adjustment, the resistance values of the grounding resistances on both sides are adjusted to achieve the adjustment of the voltage difference between the neutral wires on both sides, and to reduce the interference of the burst voltage on the communication signal in the burst experiment. Specifically, first, after measuring the first voltage information according to the preset deviation integral algorithm, the first deviation information is calculated; among them, the deviation integral algorithm is used to analyze the fluctuation of the first voltage information within a set time period. Then, according to the first deviation information, the first resistance adjustment amount information is calculated according to the preset adjustment amount algorithm; among them, the adjustment amount algorithm is a feedback control algorithm, which can improve the sensitivity of adjustment. Finally, according to the magnitude relationship between the resistance values of the grounding resistances on both sides and the first resistance adjustment amount information, the resistance value of at least one side of the grounding resistance is updated to achieve the effect of adjusting the voltage difference between the neutral wires on both sides.

[0028] Figure 2 The execution flowchart of the deviation integral algorithm provided in this embodiment is shown.

[0029] According to an embodiment of the present invention, as Figure 2 shown, according to the first voltage information and a preset voltage reference value, the first deviation information is obtained according to the preset deviation integral algorithm, specifically: S202, obtain the first period information; S204, determine the second period information according to the first period information; S206, obtain the first quantity information according to the second period information and the preset integral calculation period; S208, collect the first voltage information according to the preset second period information; S210, if the first voltage information exceeds the set first voltage range, then obtain the first deviation value according to the first voltage information and the first voltage range; S212, accumulate the first deviation value to obtain the first deviation sum; S214. Calculate the mean value based on the first quantity information and the first total deviation to obtain the first deviation information.

[0030] It should be noted that the first cycle information is the communication cycle on the communication line; the second cycle information is the sampling cycle of the first voltage information; the first quantity information is the number of times the first voltage information can be collected within a set deviation integration calculation cycle; the first deviation value is the voltage value when the first voltage information exceeds the first voltage range; the first total deviation is the sum of the first deviation values within the deviation integration calculation cycle.

[0031] In this embodiment, an execution process of a deviation integration algorithm for analyzing the fluctuation of the first voltage information within a set time period is provided. First, confirm the sampling cycle according to the data transmission communication cycle of the communication line; usually, the sampling cycle is at least twice the communication cycle to improve the accuracy of data analysis; then, determine the quantity of the first voltage information sampled within the calculation cycle according to the calculation cycle of the deviation integration algorithm. Then, if the collected first voltage information exceeds the voltage range corresponding to the level, calculate the voltage value when the first voltage information exceeds the voltage range, that is, the first deviation value, for accumulation to obtain the first total deviation. Finally, calculate the quotient of the first total deviation and the first quantity information, that is, calculate the average value of the first total deviation to obtain the first deviation information.

[0032] According to an embodiment of the present invention, the obtaining of the first deviation value based on the first voltage information and the first voltage range is specifically as follows: Obtain the level stage of the first voltage information; Obtain the first voltage range according to the level stage; Calculate the absolute value of the difference between the first voltage information and the upper limit value or the lower limit value of the first voltage range to obtain the first deviation value.

[0033] It should be noted that the level stage includes a high level stage and a low level stage, which are used to represent the digital level of the communication line. The logic levels on the communication line are usually divided into high level and low level. Taking a system with a power supply of 3.3V as an example, in the low level stage, the first voltage range is [0V, 0.7V]; in the high level stage, the first voltage range is [2.7V, 3.3V]. When the measured voltage value is outside the first voltage range of the corresponding level stage, calculate the absolute value of the difference between the first voltage information and the upper limit value or the lower limit value of the first voltage range to obtain the first deviation value; for example, in the high level stage, when the first voltage information is 3.5V, its first deviation value is 0.2V.

[0034] According to an embodiment of the present invention, the obtaining of the first resistance adjustment quantity information based on the first deviation information according to a preset adjustment quantity algorithm is specifically as follows: Obtain the first weight information, the second weight information, and the third weight information; Calculate the product of the first weight information and the first deviation information to obtain a first control quantity; Calculate the product of the second weight information and the integral value of the first deviation information to obtain a second control quantity; Calculate the product of the third weight information and the differential value of the first deviation information to obtain a third control quantity; Calculate the sum of the first control quantity, the second control quantity, and the third control quantity to obtain the first resistance adjustment quantity information.

[0035] It should be noted that the first weight information is the weight for calculating the proportional control quantity in the adjustment quantity algorithm; the second weight information is the weight for calculating the integral control quantity in the adjustment quantity algorithm; the third weight information is the weight for calculating the differential control quantity in the adjustment quantity algorithm. The first control quantity is the proportional control quantity in the adjustment quantity algorithm; the second control quantity is the integral control quantity in the adjustment quantity algorithm; the third control quantity is the differential control quantity in the adjustment quantity algorithm. In this embodiment, a feedback control algorithm is applied to improve the sensitivity of adjustment. First, calculate the product of the first weight information and the first deviation information to obtain the proportional control quantity. Secondly, obtain the integral value of the first deviation information according to the record of the first deviation information, and calculate the product in combination with the second weight information to obtain the integral control quantity. Then, obtain the differential value of the first deviation information according to the record of the first deviation information, and calculate the product in combination with the third weight information to obtain the differential control quantity. Finally, calculate the sum of the proportional control quantity, the integral control quantity, and the differential control quantity to obtain the first resistance adjustment quantity information.

[0036] Figure 3 The flowchart showing the update of the ground resistance value provided by the embodiment of the present invention is shown.

[0037] According to the embodiment of the present invention, as Figure 3 shown, updating the first resistance information or the second resistance information according to the magnitude relationship between the first resistance adjustment quantity information, the first resistance information, and the second resistance information is specifically as follows: S302. Determine the resistance adjustment direction according to the first resistance adjustment quantity information; S304. Obtain a first resistance reference value and a second resistance reference value according to the first resistance information, the second resistance information, and the resistance adjustment direction; S306. Determine whether the sum of the first resistance reference value and the second resistance reference value is greater than the first resistance adjustment quantity information; S308, if so, set a distribution weight according to the first resistance reference value and the second resistance reference value for updating the first resistance information or the second resistance information; S310, if not, update the first resistance information or the second resistance information according to the first resistance reference value and the second resistance reference value.

[0038] It should be noted that the first resistance reference value is the upper limit value of the resistance value adjustment of the first resistance to the ground; the second resistance reference value is the upper limit value of the resistance value adjustment of the second resistance to the ground. First, determine the adjustment direction of the resistance to the ground according to the first resistance adjustment amount information, that is, upward adjustment or downward adjustment; then, according to the current resistance value of the resistance to the ground and the adjustable range of the resistance value of the resistance to the ground, confirm the upper limit value of the adjustment, that is, the resistance reference value. Then, calculate the sum of the two resistance reference values to the ground for judging the magnitude relationship between the sum of the reference values and the first resistance adjustment amount information. When the sum of the reference values is greater than the first resistance adjustment amount information, after calculating the distribution weight obtained, update the resistance value of the first resistance to the ground or the resistance value of the second resistance to the ground according to the distribution weight. When the sum of the reference values is not greater than the first resistance adjustment amount information, update the resistance value of the first resistance to the ground or the resistance value of the second resistance to the ground according to the upper limit value of the resistance value adjustment.

[0039] According to an embodiment of the present invention, the setting of the distribution weight according to the first resistance reference value and the second resistance reference value for updating the first resistance information or the second resistance information is specifically as follows: Judge whether the first resistance reference value is greater than the first resistance adjustment amount information; If so, update the first resistance information according to the first resistance adjustment amount information; If not, update the first resistance information according to the first resistance reference value, and update the second resistance information according to the difference between the first resistance adjustment amount information and the first resistance reference value.

[0040] It should be noted that, as an implementation manner, the principle of preferentially adjusting the resistance value of the first resistance to the ground is adopted to update the resistance values of the two resistances to the ground. If the first resistance reference value is greater than the first resistance adjustment amount information, it means that only updating the resistance value of the first resistance to the ground can meet the resistance value adjustment requirement of the resistance to the ground; at this time, update the first resistance information according to the first resistance adjustment amount information. If the first resistance reference value is not greater than the first resistance adjustment amount information, it means that it is necessary to update the resistances to the ground on both sides at the same time to meet the resistance value adjustment requirement of the resistance to the ground; at this time, update the first resistance information according to the first resistance reference value; and update the second resistance information according to the difference between the first resistance adjustment amount information and the first resistance reference value.

[0041] It is worth mentioning that setting the allocation weight according to the first resistance reference value and the second resistance reference value for updating the first resistance information or the second resistance information further includes: Determining a third resistance reference value according to the sum of the first resistance reference value and the second resistance reference value and the first resistance adjustment amount information; Updating the first resistance information according to the difference between the first resistance reference value and the third resistance reference value; Updating the second resistance information according to the difference between the second resistance reference value and the third resistance reference value.

[0042] It should be noted that as another implementation manner, the resistance values of two resistors to ground are updated based on the principle of balance adjustment; that is, the reference values of the adjusted resistors on both sides are the same. Determine a third resistance reference value according to the sum of the first resistance reference value and the second resistance reference value and the first resistance adjustment amount information; wherein, the third resistance reference value is the target reference value of the resistor to ground after adjustment. Then update the first resistance information according to the difference between the current reference value of the resistor to ground and the target reference value.

First, according to the first resistance value adjustment amount information, determine the adjustment direction of the resistance to the ground, that is, upward adjustment or downward adjustment; then, according to the current resistance value of the resistance to the ground and the adjustable range of the resistance value of the resistance to the ground, confirm the upper limit value of the adjustment, that is, the resistance reference value. Then, calculate the sum of the two resistance reference values to the ground to judge the magnitude relationship between the sum of the reference values and the first resistance value adjustment amount information. When the sum of the reference values is greater than the first resistance value adjustment amount information, after calculating the allocated weight value, update the resistance value of the first resistance to the ground or the resistance value of the second resistance to the ground according to the allocated weight value. When the sum of the reference values is not greater than the first resistance value adjustment amount information, update the resistance value of the first resistance to the ground or the resistance value of the second resistance to the ground according to the upper limit value of the resistance value adjustment.

[0056] According to an embodiment of the present invention, setting an allocation weight value according to the first resistance reference value and the second resistance reference value for updating the first resistance information or the second resistance information specifically includes: Judge whether the first resistance reference value is greater than the first resistance value adjustment amount information; If so, update the first resistance information according to the first resistance value adjustment amount information; If not, update the first resistance information according to the first resistance reference value, and update the second resistance information according to the difference between the first resistance value adjustment amount information and the first resistance reference value.

[0057] It should be noted that, as an implementation manner, the principle of preferentially adjusting the resistance value of the first resistance to the ground is adopted to update the resistance values of the two resistances to the ground. If the first resistance reference value is greater than the first resistance value adjustment amount information, it means that only updating the resistance value of the first resistance to the ground can meet the resistance value adjustment requirement of the resistance to the ground; at this time, update the first resistance information according to the first resistance value adjustment amount information. If the first resistance reference value is not greater than the first resistance value adjustment amount information, it means that it is necessary to update the resistances to the ground on both sides simultaneously to meet the resistance value adjustment requirement of the resistance to the ground; at this time, update the first resistance information according to the first resistance reference value; and update the second resistance information according to the difference between the first resistance value adjustment amount information and the first resistance reference value.

[0058] It is worth mentioning that setting an allocation weight value according to the first resistance reference value and the second resistance reference value for updating the first resistance information or the second resistance information further includes: Determine a third resistance reference value according to the sum of the first resistance reference value and the second resistance reference value and the first resistance value adjustment amount information; Update the first resistance information according to the difference between the first resistance reference value and the third resistance reference value; Update the second resistance information according to the difference between the second resistance reference value and the third resistance reference value.

[0059] It should be noted that, as another implementation manner, the resistance values of two resistors to ground are updated by taking balance adjustment as the adjustment principle; that is, the reference values of the two adjusted resistors on both sides are made the same. Determine the third resistance reference value according to the sum of the first resistance reference value and the second resistance reference value and the first resistance adjustment amount information; where the third resistance reference value is the target reference value of the resistor to ground after adjustment. Then update the first resistance information according to the difference between the current reference value and the target reference value of the resistor to ground.

[0060] The third aspect of the present invention provides a computer-readable storage medium, which includes a program for the method of suppressing impulse groups of an electric energy meter and a terminal. When the program for the method of suppressing impulse groups of an electric energy meter and a terminal is executed by a processor, the steps of the method of suppressing impulse groups of an electric energy meter and a terminal as described in any one of the above are implemented.

[0061] In summary, a method, a system and a storage medium for suppressing impulse groups of an electric energy meter and a terminal are provided. First, according to the first voltage information and a preset voltage reference value, the first deviation information is obtained according to a preset deviation integration algorithm; then, according to the first deviation information, the first resistance adjustment amount information is obtained according to a preset adjustment amount algorithm; finally, according to the magnitude relationship between the first resistance adjustment amount information and the first resistance information and the second resistance information, the first resistance information or the second resistance information is updated; thereby adjusting the resistance values of the resistors to ground on the left and right sides in the electric energy measurement circuit, so as to adjust the voltage difference between the neutral lines on the left and right sides in the electric energy measurement circuit, and realizing reducing the interference of the impulse group voltage on the communication signal in the impulse group experiment.
