[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0041] See also Figure 1 , Figure 1 Schematic diagram of the structure of the RFID system applicable to the embodiment of the present application. Figure 1 As shown, the RFID system includes a receiver (R), an exciter (Q) and a tag (T), and the receiver and the exciter, the exciter and the tag, and the tag and the receiver can communicate with each other. The working principle of the RFID system is that the exciter sends a radio frequency signal of a certain frequency through its own antenna. When the tag enters the working area of ​​the transmitting antenna, an induced current is generated, and the tag obtains energy and is activated; the tag carries its own information to the reflected signal and sends it out through its own built-in antenna: the receiving antenna of the receiver receives the reflected signal sent from the tag.

[0042] In an RFID system, the receiver mainly performs the following operations:

[0043] 1. The receiver sends a control signal to the exciter to control the exciter, such as turning on or off the exciter's forwarding function, controlling the exciter's power / rate, etc.

[0044] 2. The receiver sends inventory signaling to the exciter, such as standard inventory signaling, query signaling (Query), query reply signaling (QueryRep), etc.

[0045] 3. The receiver receives the confirmation signaling returned by the exciter.

[0046] 4. The receiver sends a broadcast message to the exciter. The broadcast message is used by the exciter to perform frame synchronization operations and heartbeat functions (the exciter detects whether the receiver is online). The sending period of the broadcast message can be set according to the actual situation, such as setting it to send a broadcast message every 1 second.

[0047] In the RFID system, the actuator mainly performs the following operations:

[0048] 1. The exciter receives the control signaling sent by the receiver, and turns on or off the forwarding function, adjusts the power / rate, etc. according to the control signaling.

[0049] 2. The activator receives the inventory signaling sent by the receiver and forwards the inventory signaling to the tag.

[0050] 3. The activator returns confirmation signaling to the receiver, such as a command confirmation response (ACK).

[0051] In an RFID system, tags mainly perform the following operations:

[0052] 1. After the tag is charged, it carries its own information on the reflected signal and sends it to the receiver through its own built-in antenna.

[0053] The communication messages between the receiver and the actuator can be divided into the following two types:

[0054] 1. Inventory signaling: such as query signaling (Query), query reply signaling (QueryRep), etc.

[0055] 2. Control signaling: Control signaling is divided into control messages and broadcast messages. Control messages are other signaling except inventory signaling and broadcast messages.

[0056] See also Figure 2 , Figure 2 It is the signaling timing diagram of the RFID system in the prior art. Figure 2 It can be seen that there is a timing conflict between different types of signaling (such as inventory signaling and control signaling, that is, inventory signaling and broadcast messages / inventory signaling and control messages), which leads to low communication reliability. At present, in order to avoid timing conflicts between different types of signaling, if control signaling is sent during inventory, it is necessary to end the inventory first and then send the control signaling. However, this solution leads to low communication efficiency.

[0057] To solve this problem, the present application provides a communication method. The communication method provided by the present application is described in detail below with reference to the accompanying drawings through specific embodiments.

[0058] See also Figure 3 , Figure 3 It is one of the flow charts of the communication method provided in the embodiment of the present application. The communication method provided in the embodiment of the present application is executed by the receiver, and includes the following steps:

[0059] Step 101, during the inventory, sending a target signaling to an exciter, wherein the target signaling includes a first code segment and a second code segment;

[0060] The first code segment is used to indicate inventory information, and the second code segment is used to indicate control information.

[0061] See also Figure 4In the prior art, during the inventory period, there is an idle period between the sending of two inventory signals. The embodiment of the present application utilizes this idle period to send the second code segment to the exciter, which does not affect the exciter forwarding the first code segment, and can also control the exciter through the second code segment without causing interference to the tag.

[0062] The first code segment is an inventory signaling that complies with a standard protocol and is used for inventory.

[0063] The second code segment can be set according to actual needs. The second code segment is used to control the exciter during the inventory, such as turning on or off the forwarding function of the exciter, controlling the power / rate of the exciter, etc.

[0064] The second code segment may be located after the first code segment or before the first code segment. In order to further improve communication efficiency, in an optional embodiment, the second code segment is located after the first code segment. In this way, the exciter can decode and forward part of the code segments in the decoded target signaling at the same time. Since the second code segment is located after the first code segment, when decoding to the second code segment, the first code segment has been decoded and forwarded to the tag. When decoding to the second code segment, the exciter stops forwarding the remaining code segments of the first signaling (i.e., the second code segment) and performs corresponding operations according to the instructions of the second code segment. If the second code segment can be located before the first code segment, the exciter needs to decode the entire first signaling before determining the first code segment to be forwarded, which will reduce communication efficiency.

[0065] The specific form of the second code segment is not limited here, and the specific form of the second code segment includes but is not limited to the following two:

[0066] Example 1: The second code segment is in the form of post-E-TRcal.

[0067] Example 2: The second code segment is in the form of post-E-TRcal+post-control code.

[0068] In Example 1 and Example 2, E-TRcal can be set to the waveform of TRcal in the standard protocol, and E-TRcal can also be set to other waveforms except the TRcal waveform according to actual needs.

[0069] In Example 1, the waveform change of the post-E-TRcal can be used to control the physical parameters of the actuator or indicate the synchronization point of the broadcast message.

[0070] In Example 2, the end mark of the first code segment can be indicated by post-E-TRcal to distinguish the first code segment and the second code segment as different types of signaling; the control information can be indicated by post-control code, such as setting a 16-bit post-control code, and using different control codes to represent different control information. For example, the post-control code is 1000, indicating that the state of the exciter is switched from the TRAN state to the CMD state in the next step; the post-control code is 1001 to indicate antenna switching; the post-control code is 1002 to indicate that the exciter performs power adjustment.

[0071] It should be understood that the length of the post-control code can be set according to actual needs, and can be specifically determined according to the length of the idle period and the rate of the relay link (ie, the communication link between the receiver and the exciter).

[0072] It should be noted that during the inventory, when the exciter needs to be controlled, a target signaling is sent to the exciter, and when the exciter does not need to be controlled, an inventory signaling that complies with the standard protocol is sent to the exciter.

[0073] In the embodiment of the present application, the target signaling includes a first code segment and a second code segment. The first code segment is used to indicate the inventory information, and the second code segment is used to indicate the control information. By sending the target signaling to the exciter during the inventory period, the first code segment indicating the inventory information and the second code segment indicating the control information can be combined and sent, and the exciter can be directly controlled during the inventory period, thereby improving communication efficiency.

[0074] The specific content of the control information is not limited here. In one embodiment, the control information includes at least one of the following:

[0075] first control information for adjusting a physical parameter of the actuator, the physical parameter comprising at least one of power, rate and frequency;

[0076] second control information used to indicate synchronization between different types of signaling;

[0077] The third control information is used to switch the antenna of the exciter.

[0078] In one embodiment, the control information includes first control information for adjusting a physical parameter of the actuator, wherein the physical parameter includes at least one of power, rate and frequency.

[0079] For example, see Figure 5, the second code segment is in the form of post-E-TRcal. E-TRcal is designed according to the waveform of TRcal, and the waveform of TRcal is determined according to specific needs (different waveforms correspond to different control information), so as to realize the control of the physical parameters of the exciter through target signaling during the inventory. Taking power control as an example, a high level of 1.0Tari can be used to increase the power of the exciter by 1dB, and a high level of 1.5Tari can be used to reduce the power of the exciter by 1dB. Similarly, larger granularity control such as ±2dB and ±3dB can also be performed, corresponding to 2.0Tari (increase 2dB), 2.5Tari (decrease 2dB), 3.0Tari (increase 3dB), 3.5Tari (decrease 3dB), etc.

[0080] In this embodiment, the physical parameters of the actuator may be adjusted during the inventory by indicating the first control information for adjusting the physical parameters of the actuator through the second code segment in the target signaling.

[0081] It should be noted that the second code segment can also be used to indicate the adjustment of other parameters of the actuator in addition to the physical parameters, that is, during the inventory, multiple parameters can be controlled according to the change of the waveform. The control granularity can be determined according to actual needs.

[0082] During the inventory process, if the broadcast message conflicts with the inventory signaling timing, how to achieve downlink synchronization is an urgent problem to be solved.

[0083] The conflict mainly exists in the following two conflict scenarios:

[0084] Scenario 1: Broadcast message during inventory signaling;

[0085] Scenario 2: Inventory signaling during broadcast message sending.

[0086] For scenario 2, since the sending time of the broadcast message is short, you can wait until the broadcast message is sent before sending the inventory signaling, so this scenario can be ignored.

[0087] To solve the problem of how to achieve downlink synchronization in scenario one, in one embodiment, the control information includes the second control information;

[0088] The second code segment includes a first sub-code segment and a second sub-code segment, the first sub-code segment is used to indicate a synchronization command, and the second sub-code segment is used to indicate a synchronization position.

[0089] For example, see Figure 6, the E-TRcal of 2 Tari can be used to indicate the synchronization command for synchronizing the broadcast message and the inventory signaling. The post-control code (such as code 100) indicates the synchronization position, which can indicate that the broadcast message is synchronized at the 4th bit after the starting point of the target signaling. The length of a bit is calculated according to Tari. For example, if the Tari is 6.25us, the synchronization point is 25us after the starting point of the target signaling is received.

[0090] To switch the antenna of the exciter, for example, from <Exciter 1, Antenna 1> to <Exciter 2, Antenna 2>, see Figure 7 , Figure 7 It is a flow chart of switching antennas in the prior art. In the prior art, it is necessary to first send a CMD1 command (FM0 code) to stop the inventory of <exciter 1, antenna 1>, and then send a CMD2 to open the forwarding link of <exciter 2, antenna 2>.

[0091] This method has the following problems.

[0092] 1. Mis-forwarding problem: Since the exciter opens the forwarding link, some preamble and data bits will still be forwarded before the FM0 path recognizes the preamble, resulting in unpredictable results;

[0093] 2. Power-off and power-on issues: The delay in sending and processing CMD is calculated based on a Tari of 6.25us and a CMD length of 20 bits. The signaling delay is 125us. If other factors (AGC pre-control and parameter configuration, etc.) are considered, the delay will be even greater, even reaching the level of several ms. This delay is likely to cause the tag to lose power, thus affecting the expectations of the inventory algorithm.

[0094] like Figure 8 As shown in the figure, the power-on time of Tr (500us) + Ts (1500us) takes 2ms. This is because, according to the standard protocol, the reader cannot send any cmd before Ts, otherwise the tag is likely to not respond to the command, thus affecting the first inventory command after the switch. For example, the most serious loss of a Query may cause a round of inventory failure.

[0095] 3. Efficiency issues: An antenna switch may cause delays such as tag power-on and parameter configuration, and the direct efficiency loss may even reach hundreds of milliseconds. The direct efficiency loss of multiple antenna switches can reach seconds. If repeated inventory and abnormal inventory (such as failure to receive queries due to power failure) are added, the efficiency loss will be even greater.

[0096] To solve the above problem, in one embodiment, the control information includes the third control information;

[0097] The second code segment includes a third sub-code segment and a fourth sub-code segment, the third sub-code segment is used to indicate an antenna switching command, and the fourth sub-code segment is used to indicate a target antenna.

[0098] In a specific implementation, the current antenna is switched to the target antenna based on the third subcode segment and the fourth subcode segment.

[0099] For example, see Fig. 9 For example, 1000 indicates an antenna switching command, 00 represents the target antenna as antenna 1, 01 represents the target antenna as antenna 2, 10 represents the target antenna as antenna 3, and 11 represents the target antenna as antenna 4. Then 100000 indicates switching the current antenna to antenna 1.

[0100] Different codes of the fourth subcode segment correspond to different target antennas. Usually, one exciter (Q) has at most four antennas, so the fourth subcode segment is usually set to have 2 bits.

[0101] In this embodiment, the control information (CMD) for switching antennas can be sent concurrently with the inventory information. Fig.10 ,In the switching of a single exciter antenna, there is no need to send CMD separately. CMD and inventory ,information are sent concurrently, which avoids the problems of mis-forwarding and power-off and power-on, and ,also improves the efficiency of antenna switching.

[0102] See also Fig.11 , the two CMDs are sent concurrently with the inventory information (requiring a longer second code segment) to achieve seamless switching, avoiding the problems of erroneous forwarding and power-off and power-on, and also improving the efficiency of antenna switching.

[0103] In summary, the control information (CMD) for switching the antenna can be sent concurrently with the inventory information, which can reduce the delay caused by sending the CMD command separately, and can be executed synchronously with opening and closing the antenna, further improving efficiency.

[0104] In one embodiment, the first code segment and the second code segment have the same coding type, and the inventory information and the control information are distinguished by two different independent preamble codes.

[0105] In this embodiment, because the coding type of the first code segment and the second code segment is the same, it is necessary to decode two different independent preamble codes before distinguishing the inventory information from the control information, which requires increasing the buffer of the exciter. If the buffer time of the exciter is 10s, then in this embodiment, the buffer of the exciter is 10s + the time required to decode the preamble code of the second code segment. This results in a low receiving efficiency of the exciter.

[0106] In order to improve receiving efficiency, in one embodiment, the encoding type of the first code segment is different from the encoding type of the second code segment.

[0107] In this embodiment, in order to distinguish between inventory information and control information, two encoding types are used. For example, the second code segment is encoded based on the encoding type FM0 to indicate control information, and the first code segment is encoded based on the encoding type PIE to indicate inventory information.

[0108] In this embodiment, since the encoding types of the first code segment and the second code segment are different, there is no need to increase the buffer of the exciter. If the buffer time of the exciter is 10s, then in this embodiment, the buffer of the exciter is still 10s, thereby improving the receiving efficiency.

[0109] In one embodiment, after sending the target signaling to the exciter, the method further includes:

[0110] receiving feedback information sent by the exciter, wherein the feedback information is used to indicate whether the exciter successfully receives the target signaling;

[0111] In a case where the feedback information indicates that the exciter has not successfully received the target signaling, the target signaling is sent to the exciter.

[0112] In specific implementation, when the receiver sends the first code segment for indicating the inventory information, it also sends the second code segment for indicating the control information (i.e., sending the target signaling). In order to ensure the accuracy of the target information received by the exciter, the exciter can reply with ACK (carrying the post-code) after receiving the target signaling. If the Ack is wrong, the target signaling is sent to the exciter again until the receiver receives the ACK correctly. Furthermore, if the number of times the exciter sends the target signaling exceeds the preset threshold and the ACK is still wrong, it indicates that the relay link is abnormal, and the inventory can be stopped and the relay link can be re-established.

[0113] See also Fig.12 , Fig.12 This is a second flow chart of the communication method provided in the embodiment of the present application. The communication method provided in the embodiment of the present application is executed by an exciter, and includes the following steps:

[0114] Step 201, during the inventory, receiving a first signaling sent by a receiver;

[0115] Step 202: decode the first signaling, and if the first signaling contains a first code segment and a second code segment, forward the first code segment, and perform a corresponding operation according to an instruction of the second code segment;

[0116] The first code segment is used to indicate inventory information, and the second code segment is used to indicate control information.

[0117] In the case that the first signaling has a first code segment and a second code segment, the first signaling is the above-mentioned target signaling, and the second code segment is located after the first code segment.

[0118] In specific implementation, during the inventory, the exciter decodes and forwards part of the decoded code segments in the first signaling. Since the second code segment is located after the first code segment, when decoding to the second code segment, the first code segment has been decoded and forwarded to the tag. When decoding to the second code segment, the exciter stops forwarding the remaining code segments of the first signaling (i.e., the second code segment) and performs corresponding operations according to the instructions of the second code segment. For example, the exciter adjusts its own physical parameters, the exciter switches its own antenna, etc.

[0119] In one embodiment, after receiving the first signaling sent by the receiver, the method further includes:

[0120] The first signaling is decoded, and when only the first code segment exists in the first signaling, the first signaling is forwarded to a tag.

[0121] In the case that the first signaling only has the first code segment, the first signaling is the inventory signaling in the prior art, and in this case, the inventory signaling can be directly forwarded to the label.

[0122] For example, the exciter reserves a buffer of the length of E-Trcal. When the decoding finds that it is not E-Trcal, it means that the first signaling only carries inventory information, and the exciter directly forwards the first signaling. When the decoding is E-Trcal, it means that the first signaling carries inventory information and control information, and the first signaling is the target signaling. At this time, the forwarding is stopped, and the subsequent second code segment is decoded, and then the corresponding operation is performed according to the instruction of the second code segment.

[0123] In one embodiment, the control information includes any one of the following:

[0124] first control information for adjusting a physical parameter of the actuator, the physical parameter comprising at least one of power, rate and frequency;

[0125] second control information used to indicate synchronization between different types of signaling;

[0126] The third control information is used to switch the antenna of the exciter.

[0127] In one embodiment, after receiving the first signaling sent by the receiver, the method further includes:

[0128] Sending feedback information to the receiver, where the feedback information is used to indicate whether the exciter successfully receives the first signaling;

[0129] In a case where the feedback information indicates that the exciter has not successfully received the first signaling, the exciter resends the first signaling to the exciter.
