It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

[0055] The following description, in conjunction with the accompanying drawings, details the apparatus, method, and equipment for determining the operating frequency of RFID tags for power facilities provided in this application, through specific embodiments and application scenarios.
[0056] Example 1
[0057] Figure 1 This is a flowchart illustrating the device for determining the operating frequency of RFID tags for power facilities provided in Embodiment 1 of this application. Figure 1 As shown, the specific steps include the following:
[0058] Information acquisition module 101 is used to acquire at least one communication frequency of RFID tag;
[0059] The interaction module 102 is used to communicate with one antenna of the RFID tag based on the communication frequency to obtain the data content fed back by the current antenna, and to obtain the communication frequency information of the RFID tag.
[0060] The parsing module 103 is used to read the number of communication frequencies of the RFID tag and the specific value of each communication frequency based on the communication frequency information.
[0061] The communication frequency switching module 104 is used to determine the target communication frequency for interacting with the RFID tag based on the specific value of the communication frequency, and to interact with the RFID tag through the target communication frequency.
[0062] Firstly, this solution is intended for scenarios involving the collection of data from power facilities using RFID tags. This solution can be executed by the smart chip installed inside the reader or by external smart terminal devices, such as desktop computers, laptops, mobile phones, and tablets.
[0063] In this solution, the information acquisition module 101 uses the communication frequency of the RFID tag, which can be a frequency supported by one or more antennas of the RFID tag. It is understandable that one antenna can support a fixed frequency or frequency range, while when the RFID tag has multiple antennas, it can support multiple frequencies or frequency ranges.
[0064] The methods for obtaining the communication frequency of RFID tags can include the following:
[0065] 1. Based on the current basic communication frequency of the cable layout, which can be the default communication frequency used by all RFID tags installed on power facilities, such as transmitting 100-200Hz radio frequency signals, and check the other frequencies of the RFID tags contained in the returned data to obtain the communication frequency of the RFID tags.
[0066] Second, the reader internally caches the communication frequency of the RFID tag. Instructions are used to read the cached communication frequency. This can be a command executed by the reader to read data, for example, a string of binary digits consisting of an opcode and an address code. The opcode indicates that the operation to be performed is reading, and the address code indicates the content of the object being operated on or the address of its storage unit. For example, this storage unit address might be used to store the communication frequency of the RFID tag.
[0067] 3. Use the frequency sweep method. Have the reader transmit radio frequency signals within a certain frequency range, from low to high, and check for feedback within a 3-second timeframe. For example, the reader might transmit a 100-200Hz radio frequency signal and wait for feedback. If there is feedback, it indicates that the current RFID tag's communication frequency is within the 100-200Hz range. If there is no feedback, the current frequency is not the RFID tag's communication frequency. Continue having the reader transmit increasingly higher radio frequency signals, such as 200-300Hz, 300-500Hz, 500-1000Hz, etc., and wait for feedback.
[0068] For RFID tags, different frequencies produce different feedback results, and each frequency range with feedback results includes the RFID tag's communication frequency. Each communication frequency can be used to exchange different data stored in the RFID tag. This configuration in this solution can protect the data, making the data stored in the RFID tag more secure.
[0069] The interaction module 102 communicates with one antenna of the RFID tag based on the obtained communication frequency. For example, it sends a data request through the communication frequency to obtain data content fed back by the RFID tag. This data content may include information about the RFID tag, as well as other communication frequencies of the RFID tag. Specifically, the first field of the data content fed back by the RFID tag can be filled with information that needs to be fed back at the current communication frequency, such as ambient temperature, ambient humidity, cable current value, and one or more other information. The second field of the data content fed back by the RFID tag can be filled with all communication frequencies currently supported by the RFID tag, or other communication frequencies other than the currently supported communication frequency.
[0070] The parsing module 103 acquires data containing communication frequency information of the RFID tags. The data content corresponding to each communication frequency may be different. It reads the number of communication frequencies of the RFID tags and the specific values of each communication frequency from the acquired data. The number of communication frequencies is determined by the number of connectors in the field content of the data content. The specific values of the communication frequencies are analyzed according to the communication protocol. For example, the data content may contain a field including 010a-011b-100c, which can be understood as containing three communication frequencies: 100Hz, 300Hz, and 500Hz.
[0071] The communication frequency switching module 104 obtains the specific value of the communication frequency, which is the target communication frequency for interacting with the RFID tag. After determining the target communication frequency, an activation signal can be sent to the RFID tag using the currently used communication frequency. Upon receiving the activation signal, the RFID tag changes its current antenna frequency to the target communication frequency. The activation signal can be a pre-determined digital command based on the communication protocol, such as sending a 0110 digital command. After receiving the command, the antenna changes its communication frequency to the target communication frequency. The reader then transmits a radio frequency signal at the target communication frequency to interact with the RFID tag. Referring to the example above, after determining the target communication frequency to be 400Hz, an activation signal can be sent to the RFID tag using the currently used 100Hz communication frequency. Upon receiving the activation signal, the RFID tag changes its current antenna frequency to 400Hz.
[0072] In this embodiment, an information acquisition module is used to acquire at least one communication frequency of the RFID tag; an interaction module is used to communicate with one antenna of the RFID tag based on the communication frequency to acquire the data content fed back by the current antenna and acquire the communication frequency information of the RFID tag; a parsing module is used to read the number of communication frequencies of the RFID tag and the specific value of each communication frequency according to the communication frequency information; and a communication frequency switching module is used to determine the target communication frequency for interaction with the RFID tag according to the specific value of the communication frequency and interact with the RFID tag through the target communication frequency. By implementing this solution, the problems of limited use and insufficient security of single-antenna RFID tags can be solved. By acquiring at least one communication frequency of the RFID tag and interacting with the antenna to obtain the communication frequency information of the RFID tag in the data content fed back by the antenna, and reading all the communication frequencies of the RFID tag from the data content, the robustness of the communication process can be improved, and the goal of efficient information exchange can be achieved.
[0073] Based on the above technical solution, optionally, the device further includes:
[0074] The target antenna activation module is used to determine the target antenna according to the target communication frequency, and when the target antenna is different from the current antenna, to feed back target antenna activation information to the RFID tag based on the current communication frequency to activate the target antenna.
[0075] Specifically, feeding back target antenna activation information to the RFID tag can be done by feeding back activation information to the RFID tag. The activation information can be a digital command pre-determined based on the communication protocol, such as issuing a digital command of 0111.
[0076] The technical solution provided in this embodiment uses a target antenna activation module to determine a target antenna based on the target communication frequency. When the target antenna differs from the current antenna, it feeds back target antenna activation information to the RFID tag based on the current communication frequency to activate the target antenna. This allows for the activation of the target antenna even when the target antenna determined by the target communication frequency differs from the current antenna, by feeding back target antenna activation information to the RFID tag based on the current communication frequency.
[0077] Example 2
[0078] Figure 2 This is a schematic diagram of the operating frequency determination device for RFID tags used in power facilities provided in Embodiment 2 of this application. Figure 2 As shown, it specifically includes the following:
[0079] Information acquisition module 101 is used to acquire at least one communication frequency of RFID tag;
[0080] The interaction module 102 is used to communicate with one antenna of the RFID tag based on the communication frequency to obtain the data content fed back by the current antenna, and to obtain the communication frequency information of the RFID tag.
[0081] The parsing module 103 is used to read the number of communication frequencies of the RFID tag and the specific value of each communication frequency based on the communication frequency information.
[0082] The communication frequency switching module 104 is used to determine the target communication frequency for interacting with the RFID tag based on the specific value of the communication frequency, and to interact with the RFID tag through the target communication frequency.
[0083] The interaction module 102 includes:
[0084] The data content receiving unit 1021 is used to communicate with one antenna of the RFID tag based on the communication frequency to obtain the data content fed back by the RFID tag using the current antenna; wherein, the data content includes preset interaction content of the RFID tag using the current antenna;
[0085] The communication frequency information acquisition unit 1022 is used to acquire the communication frequency information of the RFID tag from a preset field of the data content fed back by the current antenna of the RFID tag.
[0086] In this embodiment, the communication process can involve the reader transmitting a radio frequency signal at a communication frequency to communicate with one antenna of the RFID tag, thereby acquiring the data content of the RFID tag. The preset interaction content can be the data content of the RFID tag at different frequencies. For example, the preset interaction content at 200Hz is communication frequency information, temperature, current, etc., while the preset interaction content at 300Hz is communication frequency information, humidity, current, etc.
[0087] The preset fields are information fields within the preset interactive content. For example, the interactive content at 200Hz might include communication frequency, temperature, and current. Its preset fields would be the corresponding communication frequency, temperature, and current. The process of acquiring communication frequency information involves obtaining the preset interactive content and then using a data read instruction to read the information from the preset communication frequency fields. This data read instruction might be a computer instruction, for example, composed of a string of binary digits, consisting of an opcode and an address code. The opcode indicates that the operation to be performed is reading, and the address code indicates the content of the operation object or the address of its storage unit. For example, this storage unit address might be used to store the information from the preset communication frequency fields within the preset interactive content.
[0088] The technical solution provided in this embodiment involves a data content receiving unit in the interaction module communicating with one antenna of the RFID tag based on the communication frequency to obtain the data content fed back by the current antenna. This data content includes preset interaction content of the RFID tag using the current antenna. The communication frequency information acquisition unit then obtains the communication frequency information of the RFID tag from preset fields in the data content fed back by the current antenna. This allows communication between the RFID tag's antenna and the current communication frequency to be conducted, and after obtaining the data content, the communication frequency information of the RFID tag can be retrieved from preset fields within the data content.
[0089] Based on the above technical solution, optionally, the parsing module 103 is further used for:
[0090] The communication frequency information in the preset field is parsed to obtain the number of subfields occupied by the communication frequency, so as to determine the number of communication frequencies of the RFID tag, and the field content of each subfield is read to determine the specific value of each communication frequency.
[0091] In this embodiment, the parsing process may involve obtaining the communication frequency information, segmenting it according to the connectors in the information, parsing the communication protocol, and then retrieving the parsed content from the subfields. For example, the communication frequency information for the 200Hz communication frequency field is 010a-011b-100c, which, after segmentation, are 010a, 011b, and 100c. After parsing, the content of the subfields is 100Hz, 300Hz, and 500cHz. The number of communication frequencies is determined based on the number of subfields in the preset communication frequency field. Reading the content of each subfield may involve using a data read command to read the field content and obtain the specific values of each communication frequency.
[0092] The technical solution provided in this embodiment, through a parsing module, analyzes the communication frequency information in the preset field to obtain the number of sub-fields occupied by the communication frequency, determines the number of communication frequencies of the RFID tag, and reads the content of each sub-field to determine the specific value of each communication frequency. It can parse the communication frequencies in the preset field and, by analyzing the number of sub-fields occupied by the communication frequency and the content of each sub-field, achieve the effect of determining the number of communication frequencies of the RFID tag and the specific value of each communication frequency.
[0093] Example 3
[0094] Figure 3 This is a schematic diagram of the operating frequency determination device for RFID tags used in power facilities provided in Embodiment 3 of this application. Figure 3 As shown, it specifically includes the following:
[0095] Obtain the interaction information corresponding to the specific values of each of the aforementioned communication frequencies;
[0096] Determine the target interaction information;
[0097] Based on the target interaction information, the target communication frequency for interacting with the RFID tag is determined, and the interaction with the RFID tag is performed through the target communication frequency.
[0098] The interactive information refers to other information corresponding to the specific numerical value of each communication frequency. For example, when the communication frequency is 200 Hz, the corresponding interactive information might be temperature, current, etc. When the communication frequency is 300 Hz, the corresponding interactive information might be humidity, current, etc. The target interactive information is the corresponding information you want to obtain, and the communication frequency is determined based on the target interactive information. You can understand it as wanting to obtain interactive messages about temperature and current. Therefore, temperature and current are the target interactive information, and the communication frequency corresponding to the target interactive information is the target communication frequency. Interaction with the RFID tag is conducted through the target communication frequency.
[0099] This technical solution provides a method to determine target interaction information based on specific values of communication frequencies, and from this, determine the target communication frequency for interacting with the RFID tag. This solves the problem of determining target interaction information based on specific values of communication frequencies, achieving the effect of interacting with the RFID tag based on the target communication frequency in the target interaction information.
[0100] Based on the above technical solution, optionally, the communication frequency switching module 104 is further used for:
[0101] Obtain the identity information of RFID tags;
[0102] Based on the identity information, obtain a table from the target server relating the communication frequency and interaction information of the RFID tag;
[0103] Read the interaction information corresponding to the specific values of each of the communication frequencies from the associated table.
[0104] The RFID tag's identity information can be a unique, unchangeable identifier stored in its TID (Trust Identifier). The target server can be a large database storing an association table for each RFID tag. This association table consists of the RFID tag's communication frequency field and other information fields, populated by interactive information. Obtaining the RFID tag's identity information can be done by sending a read command. Alternatively, the target server can retrieve the association table by sending a data read command carrying the RFID tag's identity information. The read command then retrieves the interactive information corresponding to the specific communication frequency value in the association table.
[0105] The technical solution provided in this embodiment obtains the identity information of the RFID tag through the communication frequency switching module 104, and retrieves an association table of the RFID tag's communication frequency and interaction information from the target server based on the identity information. The interaction information corresponding to the specific values of each communication frequency is read from the association table. This solves the problem of retrieving the association table from the target server based on the RFID tag's identity information, achieving the effect of reading the interaction information corresponding to the specific values of each communication frequency in the association table.
[0106] The device for determining the operating frequency of the RFID tag for power facilities in this application embodiment can be a device, or a component, integrated circuit, or chip in a terminal. This device can be a mobile electronic device or a non-mobile electronic device. For example, mobile electronic devices can be mobile phones, tablets, laptops, PDAs, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc., while non-mobile electronic devices can be servers, network-attached storage (NAS), personal computers (PCs), televisions (TVs), ATMs, or self-service machines, etc. This application embodiment does not impose specific limitations.
[0107] The device for determining the operating frequency of RFID tags for power facilities in this embodiment can be a device with an operating system. This operating system can be Android, iOS, or other possible operating systems; this embodiment does not specifically limit its use.
[0108] Example 4

[0110] S401, acquire at least one communication frequency of the RFID tag through the information acquisition module;
[0111] S402, the interaction module communicates with one antenna of the RFID tag at the communication frequency to obtain the data content fed back by the current antenna, and obtains the communication frequency information of the RFID tag;
[0112] S403, the parsing module reads the number of communication frequencies of the RFID tag and the specific value of each communication frequency according to the communication frequency information;
[0113] S404, the communication frequency switching module determines the target communication frequency for interacting with the RFID tag based on the specific value of the communication frequency, and interacts with the RFID tag through the target communication frequency.
[0114] Furthermore, the method also includes:
[0115] The parsing module parses the communication frequency information in the preset field to obtain the number of subfields occupied by the communication frequency, thereby determining the number of communication frequencies of the RFID tag, and reads the field content of each subfield to determine the specific value of each communication frequency.
[0116] Furthermore, the method also includes:

[0124] Furthermore, the method also includes:
[0125] The target antenna activation module determines the target antenna based on the target communication frequency. If the target antenna differs from the current antenna, it sends target antenna activation information back to the RFID tag based on the current communication frequency to activate the target antenna. This solution addresses the limitations and security issues of single-antenna RFID tags. By acquiring at least one communication frequency of the RFID tag and interacting with the antenna, the communication frequency information of the RFID tag is obtained from the data fed back by the antenna. All communication frequencies of the RFID tag are read from the data content, improving the robustness of the communication process and achieving efficient information exchange.
