Technical Field

[0001] The present invention relates to the technical field of data acquisition, and in particular to a wireless communication acquisition method for a three-phase smart electric energy meter. Background Art

[0002] With the popularization of new energy vehicles, charging piles, as a crucial infrastructure in the use of electric vehicles, have gradually become the focus of urban development and traffic management; the existing charging pile networks are mostly built by power companies or commercial service providers; however, due to the insufficient number of charging piles, uneven distribution and poor management, users often encounter great difficulties in finding charging piles; with the increase in the popularity of electric vehicles, the demand for home charging piles is increasing day by day; traditional home charging piles are usually only for private use, but in order to improve resource utilization efficiency, more and more home charging piles have begun to be opened to the public and provided to other users; however, this also brings new challenges, that is, how to efficiently and conveniently allow users to find suitable open charging piles and properly arrange charging time.

[0003] Traditional methods of finding charging piles mostly rely on a single geographic location screening method, that is, charging piles are recommended only based on the geographic location of the charging pile and the user's current location. This method fails to take into account the differences in user charging needs and the real-time status of the charging pile. For example, factors such as the user's vehicle model, power level, charging target, and remaining mileage will have an important impact on the choice of charging pile. At the same time, some charging piles have time period restrictions, such as time periods that only allow owners to use them. These have not been fully considered in traditional methods, resulting in low utilization of charging piles and user experience.

[0004] In summary, there is an urgent need for a wireless communication collection method for a three-phase smart energy meter to realize the intelligent allocation of charging pile resources and improve the efficiency and safety of the charging process through real-time monitoring of the three-phase smart energy meter.

[0012] Optionally, also include: According to the recommendation strategy, charging piles are pushed to users when they are looking for charging piles. Specifically: Setting a probability threshold, which is used to determine whether to push a charging pile to the user; When users look for home charging stations open to the public on the charging platform; Obtain all charging piles that meet the charging conditions of this user to form a target set; For any charging pile in the target set; Get the total probability of being selected by other users; If the total probability of a charging pile being selected by other users is greater than or equal to the probability threshold, when the user searches for an open home charging pile on the charging platform, the charging pile will not be displayed to the user; If the total probability of a charging pile being selected by other users is less than the probability threshold, when the user searches for an open home charging pile on the charging platform, the user displays the charging pile; If there are charging piles in the fourth set within the user's sub-path, when the user searches for home charging piles open to the public on the charging platform, only the charging piles in the fourth set within the sub-path will be displayed to the user.

[0013] Optionally, also include: When the user arrives at the charging station, the user confirms arrival on the charging platform; For a charging station; If there are multiple users queuing at the same charging station; The actual output power of the charging pile is collected through a three-phase smart meter; Set the minimum charging power threshold; The minimum charging power threshold is used to determine whether to terminate the charging operation of the current charging vehicle; If the actual output power of the charging pile is less than or equal to the minimum charging power threshold, the charging operation for the current vehicle will be stopped.

[0014] The present invention has the following beneficial effects: 1. The wireless communication acquisition method of the three-phase smart energy meter obtains the central position of the first user, and draws a circle with the central position of the user as the center and the remaining distance as the radius to form a circular domain; obtains all the household charging piles open to the public in the circular domain and constitutes a first set; the charging piles outside the circular domain are charging piles that cannot be reached based on the remaining mileage of the first user's vehicle, and the charging piles within the circular domain are charging piles that may be reached based on the remaining mileage of the first user's vehicle; then for each charging pile in the first set, obtain the distance of the shortest travel path to the central position, if the distance is greater than the remaining distance, it means that the user cannot reach the charging pile, if the distance is less than the remaining distance, it means that the user can reach the charging pile, and the charging piles in the first set whose distance to the shortest travel path to the central position is less than the remaining distance constitute a second set; subsequently, the charging piles are searched in the second set for charging, and in this way, the charging piles that cannot be reached based on the remaining mileage of the first user's vehicle can be preliminarily excluded, avoiding the situation that the first user cannot reach the charging pile, thereby improving the user experience.

[0015] 2. The wireless communication collection method of the three-phase smart energy meter obtains the rated charging power of each charging pile in the second set, and then estimates the estimated remaining power percentage of the vehicle when the first user arrives at the charging pile, and calculates the charging time required by the first user according to the estimated remaining power percentage, the charging target power percentage, the vehicle model and the charging pile power; estimates the charging interval required by the first user according to the charging time required by the first user, and obtains the time interval set by the owner of the charging pile when the charging pile is not open to the public, which is recorded as the prohibited charging time interval; combines the charging interval required by the first user and the prohibited charging time interval to determine whether the charging pile meets the conditions; if there is an intersection between the actual charging interval and the prohibited charging time interval, it means that if the first user goes to this charging pile to charge, it will be at the charging pile. The first user will charge the battery within the prohibited charging time interval set by the owner, thereby hindering the charging experience of the owner of the charging pile; if the actual charging interval and the prohibited charging time interval do not overlap, it means that if the first user goes to this charging pile to charge, the charging will not be carried out within the prohibited charging time interval set by the owner of the charging pile, and the charging experience of the owner of the charging pile will not be hindered; the charging piles in the second set whose actual charging interval and the prohibited charging time interval do not overlap constitute a third set, and charging piles are subsequently sought in the third set; the charging piles selected by this method ensure that the first user can charge at a suitable time period; this optimization not only improves the user experience of the first user, but also improves the user experience of the owner of the charging pile, and avoids charging conflicts caused by time management problems of the charging pile.

[0016] 3. The wireless communication collection method of the three-phase smart electric energy meter obtains the working status of each charging pile in the actual charging range for each charging pile in the third set. If the working status of the charging pile in the actual charging range is charging, the first user will queue up to charge at this charging pile; therefore, only the charging piles whose working status in the actual charging range is idle are selected to form the fourth set; through this method, the waiting time before the first user charges can be avoided, thereby improving the user experience of the first user.

[0017] 4. The wireless communication collection method of the three-phase smart energy meter obtains the destination of the user and the shortest travel path from the center position to the destination of the user, and combines the remaining distance to determine whether there is a charging pile in the fourth set during the remaining distance of the first user's travel along the target travel path. If there is no charging pile in the fourth set, it means that there is no charging pile along the way in the first user's driving path. At this time, for all charging piles in the fourth set, the actual distance from the center position to the charging pile position is obtained respectively, and the inverse of the actual distance is calculated as the inverse distance value, and the sum of the inverse distance values ​​of all charging piles is obtained. For one charging pile, the inverse distance value from this charging pile to the center position is calculated ÷ the sum of the inverse distance values ​​of all charging piles in the fourth set to the center position. The result is the probability that the first user goes to this charging pile; if there is a charging pile in the fourth set, then This indicates that there are charging piles along the way in the first user's driving route. At this time, only the charging piles along the way are considered; the charging piles in the fourth set that exist in the sub-paths constitute the fifth set; at this time, for all the charging piles in the fourth set, the actual distance from the center position to the charging pile position is obtained respectively, and the inverse of the actual distance is calculated as the inverse distance value, and the sum of the inverse distance values ​​of all the charging piles is obtained. For one charging pile, the inverse distance value from this charging pile to the center position is calculated ÷ the sum of the inverse distance values ​​from all the charging piles in the fifth set to the center position, and the result is the probability of the first user going to this charging pile; when there is a charging pile along the way, the user is likely to not go to the charging piles that are not along the way. By making this distinction, the probability of the user going to each charging pile is more accurate; by analyzing the user's sub-paths and recommending charging piles in the paths, the system can provide services to users more intelligently.

[0018] 5. The wireless communication acquisition method of the three-phase smart energy meter, when the user is looking for a charging pile, first obtain all the charging piles that meet the user's charging conditions to form a target set; for each charging pile in the target set, obtain its total probability of being selected by other users, and set a probability threshold; if the total probability of the charging pile being selected by other users is ≥ the probability threshold, it means that this charging pile has been selected by other users with a high probability, so when the user is looking for a charging pile, this charging pile is not displayed to the user; if the total probability of the charging pile being selected by other users is < the probability threshold, it means that this charging pile has not been selected by other users with a high probability, so when the user is looking for a charging pile, this charging pile is displayed to the user; in this way, when the user is looking for a charging pile, only the charging piles with a high probability of being idle can be displayed, avoiding the situation where the user has to queue up after going to the charging pile, which improves the user experience to a certain extent.

[0019] 6. The wireless communication collection method of the three-phase smart energy meter, when there is a queue for charging at a charging pile, obtains the actual output power of the charging pile and sets the minimum charging power threshold. If the actual output power of the charging pile is ≤ the minimum charging power threshold, it means that the vehicle being charged at this time is about to be fully charged. Due to the factor of protecting the battery, the actual charging speed is reduced. If the battery is fully charged at this time, it will take a long time. Therefore, the charging operation of the current vehicle is stopped at this time, and the charging operation of the vehicles in the queue is carried out. In this way, the charging time of the owners in the queue can be saved, and the charging pile can charge more electricity to different cars as much as possible, thereby improving the economic benefits of the owners of the charging piles.

[0028] Also includes: When the user arrives at the charging station, the user confirms arrival on the charging platform; For a charging station; If there are multiple users queuing at the same charging station; The actual output power of the charging pile is collected through a three-phase smart meter; Set the minimum charging power threshold; The minimum charging power threshold is used to determine whether to terminate the charging operation of the current charging vehicle; If the actual output power of the charging pile is less than or equal to the minimum charging power threshold, the charging operation for the current vehicle will be stopped; The wireless communication collection method of the three-phase smart energy meter, when there is a charging queue at a charging pile, obtains the actual output power of the charging pile and sets the minimum charging power threshold. If the actual output power of the charging pile is ≤ the minimum charging power threshold, it means that the power of the vehicle being charged at this time is about to be fully charged. Due to the factor of protecting the battery, the actual charging speed is reduced. If the battery is fully charged at this time, it will take a long time. Therefore, the charging operation of the current vehicle is stopped at this time, and the charging operation of the vehicles in the queue is performed. In this way, the charging time of the owners of the queue can be saved, and the charging pile can charge more power to different cars as much as possible, thereby improving the economic benefits of the owners of the charging piles.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
