[0003] Usually, RFID (Radio Frequency Identification) tags are pasted or embedded on the battery. When the user replaces the battery through the battery swap cabinet, the RFID identification device on the battery swap cabinet triggers the battery swap process of the battery swap cabinet by scanning the RFID tag. However, when the battery swap cabinets are placed side by side, the scanning areas of the RFID identification devices of the side-by-side battery swap cabinets will overlap.

[0046] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0047] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The main solution of the embodiment of the present application is: the battery swap cabinet controller obtains the signal strength record of each battery swap cabinet scanning the RFID tag of the battery to be replaced; then determines the decision value of each battery swap cabinet based on each signal strength record; and selects the battery swap cabinet with the largest decision value as the operating battery swap cabinet for replacing the battery to be replaced, and determines the selection result.

[0049] In this embodiment, for ease of description, the following description will be made using the battery swap cabinet controller as the executing entity.

[0050] Since RFID tags are usually attached or embedded on batteries, when users replace batteries through a battery swap cabinet, the RFID identification device on the cabinet triggers the battery swap process by scanning the RFID tags. However, when the battery swap cabinets are placed side by side, the scanning areas of the RFID identification devices of the side-by-side cabinets will overlap. If the user places the battery in the overlapping area, multiple cabinets may identify the RFID tags on the battery, causing the doors of multiple cabinets to open at the same time, adding unnecessary business load to the cabinet system.

[0051] The present application provides a solution, by obtaining the signal strength record of each power swap cabinet scanning the RFID tag of the battery to be replaced, determining the decision value of each power swap cabinet, and then selecting the power swap cabinet with the largest decision value as the operating power swap cabinet for performing the battery swap operation on the battery to be replaced. That is, after each power swap cabinet scans the RFID tag of the battery to be replaced, since the signal strength record of each power swap cabinet scanning the battery to be replaced is different, the decision value that needs to be operated for each power swap cabinet can be determined through the signal strength record, and according to the decision value, one operating power swap cabinet for performing the battery swap operation for the battery to be replaced is selected from each power swap cabinet, so as to avoid the situation where multiple power swap cabinets scan the RFID tag of the battery to be replaced and all perform the cabinet opening operation for the battery to be replaced. Therefore, after multiple power swap cabinets scan the RFID tag of the same battery to be replaced, the decision value of each power swap cabinet is determined by the signal strength record obtained after scanning the RFID tag, and according to the decision value, a suitable operating power swap cabinet is selected from the multiple power swap cabinets to replace the battery to be replaced, thereby reducing the business load of the power swap cabinet system.

[0052] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a battery swap cabinet controller, etc. The following takes the battery swap cabinet controller as an example to illustrate this embodiment and the following embodiments.

[0053] Based on this, the embodiment of the present application provides a method for selecting and operating a power exchange cabinet, referring to Figure 1 , Figure 1 A flowchart of the first embodiment of the method for operating a battery swap cabinet selected for this application.

[0054] In this embodiment, the method for selecting and operating a power exchange cabinet includes steps S10 to S30:

[0055] Step S10, obtaining the signal strength record of each battery swap cabinet scanning the RFID tag of the battery to be replaced;

[0056] It should be noted that the battery to be replaced can be a battery that the user needs to replace, and the battery is embedded with an RFID tag. The RFID tag can be an electronic tag that stores the battery code. The RFID tag consists of a chip and an antenna, and uses radio frequency signals for communication. It can read and write data without linear alignment scanning, which improves the efficiency of data collection. Among them, the battery code can be understood as the identity information of the battery to characterize the uniqueness of the battery. The signal strength record can be information such as the recorded signal strength and the timestamp of scanning the RFID tag.

[0057] It should also be noted that the signal strength can be used to characterize the quality of information obtained by scanning the RFID tag. The stronger the signal strength, the higher the quality of information obtained by scanning the RFID tag, that is, the strength of the radio frequency signal received from the RFID tag. The timestamp can be the time point of the battery code of the battery to be replaced obtained by scanning the RFID tag.

[0058] It is understandable that since the battery to be replaced is placed in the overlapping RFID scanning area of ​​the side-by-side power exchange cabinets, multiple power exchange cabinets may scan the RFID tag of the battery to be replaced. In order to avoid multiple power exchange cabinets opening the doors for the battery to be replaced, a signal strength record is obtained, including the signal strength when each power exchange cabinet scans the RFID tag and the timestamp when the RFID tag is scanned, so as to facilitate the selection of a power exchange cabinet for replacing the battery to be replaced from multiple power exchange cabinets through the two dimensions of signal strength and time.

[0059] Step S20, determining a decision value of each of the power swap cabinets based on each of the signal strength records;

[0060] It should be noted that the decision value can be a judgment condition for determining whether the battery swap cabinet needs to be operated. Since the decision value is determined based on the signal strength record, the decision value can also represent the value after comprehensive processing of the signal strength and timestamp.

[0061] It is understandable that in order to find a battery swap cabinet with a strong signal strength and which can quickly scan the RFID tag, it is necessary to determine the signal quality of each battery swap cabinet scanning the RFID tag based on the signal strength record. In other words, determine the decision value after comprehensive processing of the signal strength and timestamp, so as to facilitate the determination of the battery swap cabinet that needs to replace the battery to be replaced based on the decision value.

[0062] Step S30, selecting the battery swap cabinet with the largest decision value as the operating battery swap cabinet for replacing the battery to be replaced, and determining the selection result.

[0063] It should be noted that the operating battery swap cabinet may be the battery swap cabinet determined to be the battery swap cabinet for battery replacement, that is, the selection result will be sent to the operating battery swap cabinet.

[0064] It is understandable that since the decision value is determined based on the signal strength and timestamp, and the environment between the battery to be replaced and each battery swap cabinet will affect the signal strength and timestamp, and will also affect the convenience of the user replacing the battery, therefore, the battery swap cabinet with the largest decision value can be selected to replace the battery to be replaced. According to the signal strength and timestamp of the RFID tag scanned by each battery swap cabinet, the operating battery swap cabinet for the battery to be replaced that is convenient for the user to replace is screened out, thereby avoiding multiple battery swap cabinets opening the door for the same battery.

[0065] In the specific implementation, the maximum value is filtered out from the decision values ​​of each battery swap cabinet, and then the corresponding battery swap cabinet is marked as the operating battery swap cabinet to perform the battery swap operation of the battery to be replaced, and information characterizing the identity of the battery swap cabinet is obtained. Then, the selection result of the battery swap cabinet is obtained based on the information and the decision value, so as to facilitate the subsequent control of the operating battery swap cabinet to open the door for replacement for replacement according to the selection result, and avoid the other battery swap cabinets from opening the door for the battery to be replaced.

[0066] Optionally, in order to ensure that each power swap cabinet determines the selection result and to avoid that some power swap cabinets fail to determine the selection result and still open the compartment door for the battery to be replaced, after step S30, the method for selecting and operating the power swap cabinet may further include:

[0067] Broadcast the selection result, start timing, and record the timing duration;

[0068] When the timing duration meets the anti-concurrency time, the operation of the power exchange cabinet is controlled to open the door.

[0069] It should be noted that the timing duration can be the time difference from the start of broadcasting the selection result to the current time point. The anti-concurrency time can be the time to ensure that each power exchange cabinet can determine the selection result. The anti-concurrency time can be the average time of broadcasting the selection result based on the historical response of each power exchange cabinet. Among them, broadcasting the selection result can be to propagate the final selection result to each power exchange cabinet by broadcasting.

[0070] It is understandable that when the battery swap cabinet does not receive the selection result within a certain period of time, it will mistakenly determine that the battery swap cabinet controller is faulty, or the transmission path of the battery swap cabinet controller is faulty, so it fails to receive the selection result, and then determines that the selected power swap cabinet is this power swap cabinet. In order to make each power swap cabinet determine the selection result, and then control the operation of the power swap cabinet to open the door, to avoid the power swap cabinet opening the door for the battery to be replaced when the selection result is not determined, it is necessary to start timing after the selection result is broadcast. After the timing time meets the average time required for each power swap cabinet to determine the selection result, it is determined that each power swap cabinet has determined the selection result. At this time, the power swap cabinet is controlled to open the door, which can avoid the other power swap cabinets from opening the door for the battery to be replaced, thereby reducing the business load of the power swap cabinet system.

[0071] Optionally, in order to ensure that each battery swap cabinet can determine the selection result in a timely manner, the operating battery swap cabinet that receives the selection result continues to broadcast the selection result to speed up the rate at which the remaining battery swap cabinets obtain the selection results.

[0072] In the specific implementation, it is necessary to process the battery RFID tags read on this battery swap cabinet one by one; check whether all parallel placed battery swap cabinets have broadcast the battery swap cabinet selection result with this tag; if so, check whether the selected battery swap cabinet is this battery swap cabinet through selCabinetRecords. If so, start the battery swap process and delete the information corresponding to the tag from RFIDRSSIs; if this battery swap cabinet has made a decision, and the current time and decision time tsSel are greater than the anti-concurrency time, the information corresponding to the tag is deleted from RFIDRSSIs.

[0073] The present embodiment provides a method for selecting an operating power swap cabinet, by obtaining the signal strength record of each power swap cabinet scanning the RFID tag of a battery to be replaced, determining the decision value of each power swap cabinet, and then selecting the power swap cabinet with the largest decision value as the operating power swap cabinet for performing the battery swap operation on the battery to be replaced. That is, after each power swap cabinet scans the RFID tag of the battery to be replaced, since the signal strength records of each power swap cabinet scanning the battery to be replaced are different, the decision value that needs to be operated for each power swap cabinet can be determined through the signal strength record, so as to select an operating power swap cabinet for performing the battery swap operation from each power swap cabinet according to the decision value, so as to avoid the situation where multiple power swap cabinets scan the RFID tag of the battery to be replaced and all perform the cabinet opening operation for the battery to be replaced. Therefore, after multiple power swap cabinets scan the RFID tag of the same battery to be replaced, the decision value of each power swap cabinet is determined by the signal strength record obtained after scanning the RFID tag, and a suitable operating power swap cabinet is selected from multiple power swap cabinets to perform the battery swap operation for the battery to be replaced according to the decision value, thereby reducing the business load of the power swap cabinet system.

[0074] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S20 also includes steps S01 to S04:

[0075] Step S01, filtering effective strength information that meets a preset strength value within a preset time period from each of the signal strength records;

[0076] It should be noted that the preset strength value may be a signal strength that can ensure that the battery swap cabinet obtains complete RFID tag information. The effective strength information may be information about the signal strength of the complete RFID tag information obtained by the battery swap cabinet. The preset duration may be the time from the acquisition time point of the signal strength with reference value to the current time point. Since the factors affecting the signal strength between the battery swap cabinet and the battery to be replaced are constantly changing, the farther from the current time point, the smaller the reference value of the signal strength of the RFID tag. Therefore, it is necessary to determine the preset duration to obtain a signal strength with reference value within the preset duration.

[0077] It can be understood that since the signal strength of the RFID tag of the battery to be replaced scanned by each power swap cabinet is different, the lower the signal strength, the lower the information quality of the scanned RFID tag, and each power swap cabinet scans the RFID tag periodically, that is, the RFID tag is scanned once every predetermined period of time to update the information quality of the scanned RFID tag. Therefore, step S01 can be performed to filter out the valid strength information within the preset time period and with the signal strength meeting the preset strength value from the multiple information scanned by the RFID tag of each power swap cabinet, thereby avoiding processing of signal strength and timestamps with low quality and not within the reference time range, thereby reducing the screening time and improving the efficiency of selecting and operating the power swap cabinet.

[0078] Step S02, reading the timestamp of each scan of the RFID tag from the effective strength information;

[0079] It should be noted that the timestamp can be the time point of each scan of the RFID tag. Since each power swap cabinet has different capabilities to determine signal strength, it is possible that the power swap cabinet that scans the RFID tag first determines the signal strength later than the power swap cabinet that scans the RFID tag later. However, scanning the RFID tag first indicates that the battery to be replaced is closer to the power swap cabinet, or there are fewer obstructions between the battery to be replaced and the power swap cabinet, which makes it more convenient for users to replace the battery. Therefore, the timestamp represents the time point of each scan of the RFID tag.

[0080] Step S03, reading a determination parameter of a decision value from the effective strength information based on the timestamp;

[0081] It should be noted that the determination parameter may be the signal strength required to determine the decision value, so as to accurately determine the decision value of each battery swap cabinet based on this information.

[0082] Step S04: determine the decision value of the battery swap cabinet based on the determined parameters and the corresponding timestamp.

[0083] It can be understood that by utilizing the determined parameters and the corresponding timestamps to determine the decision value of the battery swap cabinet, it is convenient to subsequently select the operating battery swap cabinet from the two dimensions of signal strength and time through the decision value, so as to screen the battery swap cabinets with relatively stable signal strength for scanning RFID tags from the battery swap cabinets as the operating battery swap cabinets, that is, determine the battery swap cabinet with the largest decision value as the operating battery swap cabinet.

[0084] It is understandable that since both signal strength and timestamp can be automatically obtained, it is also possible to support automatic battery swap cabinet selection decisions from the two dimensions of signal strength and time, providing an efficient and available solution for battery swap cabinet selection.

[0085] Furthermore, step S01 may also include:

[0086] Filtering a signal strength set at a time point of scanning the RFID tag that satisfies a preset time length from each of the signal strength records;

[0087] Screening invalid signal strengths whose signal strengths do not meet a preset strength value from the signal strength set;

[0088] The records corresponding to the invalid signal strengths are deleted from each of the signal strength sets to obtain valid strength information that meets the preset strength value.

[0089] It should be noted that the invalid signal strength may be a signal strength that has no reference value for determining the operation of the power swap cabinet.

[0090] It is understandable that since the signal strength is obtained too early or the signal strength is too small, the signal strength has no reference value. In order to reduce the computing power required to determine the decision value of each battery swap cabinet, the time point of scanning the RFID tag is screened from the signal strength record to meet the time range (preset duration) with reference value, reducing the meaningless signal strength that is too early; in order to reduce the impact of the poor signal strengths in the signal strength set on the accuracy of determining the decision value, the invalid signal strength that does not meet the preset strength value is screened out from the signal strength set that meets the preset time requirement, and the invalid signal strength is deleted from the signal strength set, and the record of the invalid signal strength is deleted to obtain valid strength information that meets the preset strength value. Therefore, the accuracy and speed of screening the operating battery swap cabinets from the battery swap cabinets can be improved.

[0091] Further, the determined parameter includes the first signal strength and the second signal strength, and the step S03 further includes:

[0092] Marking the earliest first timestamp and the latest second timestamp within the preset time length from the timestamps;

[0093] A first signal strength obtained by scanning the RFID tag at the first time stamp is read from the effective strength information, and a second signal strength obtained by scanning the RFID tag at the second time stamp is read.

[0094] In the specific implementation, for a battery RFID tag RFIDA, the RFID cabinet selection decision value is calculated for each battery swap cabinet that reports the battery RFID tag signal according to the following formula:

[0095] selCabinetRef = (RSSIn - RSSI0) * K / (tsn - ts0)

[0096] Among them: RSSIn is the battery RFID tag RSSI obtained by the RFID power cabinet for the last time;

[0097] RSSI0 is the battery RFID tag RSSI obtained by the RFID power cabinet at the earliest time;

[0098] tsn is the timestamp of the battery RFID tag last obtained by the RFID cabinet;

[0099] ts0 is the timestamp of the battery RFID tag obtained by the RFID cabinet the earliest time;

[0100] The K value is the result amplification factor, and its value should be greater than t3. It is generally recommended to be 10 times of t3. For example, if t3 is selected as 1000ms, the K value is recommended to be 10000. The most effective value actually depends on the specific test results. Among them, t3 can be the periodicity of the battery swap cabinet scanning the RFID tag, that is, scanning the RFID tags one by one every t3 time period.

[0101] The RFID battery swap cabinet with the largest selCabinetRef value is selected as the battery swap cabinet for the battery RFID battery tag, and the record is selCabinetRecords, whose parameters include the battery RFID tag code RFIDSN, the battery swap cabinet code cabinetSN and the decision time point tsSel.

[0102] In particular, if a tag reports the battery RFID tag signal strength only on one battery swap cabinet, there is no need for calculation and the battery swap cabinet with the battery RFID tag can be directly selected as the battery swap cabinet.

[0103] In particular, if two or more battery swap cabinets have the same selCabinetRef calculated for a certain tag, the battery swap cabinet that reports the tag earliest is selected as the selected battery swap cabinet.

[0104] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 3 , step S10 also includes steps S1 to S3:

[0105] Step S1, obtaining the signal strength of each power swap cabinet scanning the RFID tag of the battery to be replaced from the power swap cabinet that scans the RFID tag;

[0106] Step S2, obtaining the timestamp of each of the power swap cabinets scanning the RFID tag;

[0107] Step S3, based on the timestamp and the corresponding signal strength, obtain the signal strength record of the corresponding power exchange cabinet scanning the RFID tag.

[0108] It can be understood that since the signal strength represents the scanning quality and transmission rate of the power swap cabinet scanning the RFID tag, in order to screen out the power swap cabinets with high scanning quality and fast transmission rate from multiple power swap cabinets, it is necessary to obtain the signal strength of each power swap cabinet scanning the RFID tag. Since the faster the power swap cabinet scans the RFID tag, that is, the faster the transmission rate, the fewer obstructions or the closest distance between the power swap cabinet and the battery to be replaced, and the more convenient it is to replace the battery to be replaced. Therefore, the timestamp of each power swap cabinet scanning the RFID tag can also be obtained to facilitate the subsequent screening of the signal strength according to the timestamp.

[0109] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the method of selecting and operating the battery swap cabinet in the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
