Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1, in a first embodiment of an RFID data transmission method of the present invention, the method includes:
s1, scanning all RFID available channels corresponding to the RFID data transmission in the network to obtain the available levels of the RFID available channels; that is, before the RFID data transmission is established, a transmission channel corresponding to the RFID data is obtained through channel scanning, and may also be understood as a channel capable of supporting the RFID data transmission protocol, that is, an RFID available channel. Meanwhile, the available grades of all the RFID available channels are established according to the scanning result in the scanning process or after the scanning is finished. That is, the scanned available channels of the RFID are evaluated to confirm the possibility that the available channels can be used for transmitting RFID data, and the available levels are ranked according to the possibility of use, with the higher the possibility, the higher the available level; the lower its probability, the lower the available rank, and the selection of the actually used channel is made in the order in actual use. The network may be understood as a 2.4GMz bandwidth network.
S2, acquiring a first channel and a second channel according to the available grade, and synchronizing the first channel and the second channel; according to the above obtained available rank ordering, two channels satisfying the condition, i.e., a first channel and a second channel, are selected from the available rank ordering and are subjected to channel synchronization. The transmission of the RFID data will be performed later on the basis of the two channels after synchronization.
S3, splitting the RFID data according to a first preset rule, and transmitting the split data through a first channel and a second channel according to a second preset rule. And splitting and analyzing the RFID data, wherein the RFID data can be original data or data processed by a compression algorithm. After the RFID data is split, the split data is transmitted through a first channel and a second channel according to a preset rule, that is, a second preset rule, that is, the processed RFID data obtains a small data block, the small data block can be transmitted through one channel, for example, the first channel, and after the first channel is completely transmitted, the data block is transmitted again through another channel, for example, the second signal, and then the data block is transmitted back to the previous channel, that is, the first channel, to form the repeated transmission of the split small data blocks by two channels in sequence, and the process can be understood as a processing process in which the frequency hopping processing process is similar to the frequency hopping processing. The two optimal transmission channels are selected for alternate and repeated transmission of communication data, so that the communication quality is improved, and the anti-interference capability in data transmission is improved.
Optionally, as shown in fig. 2, in step S1, scanning all RFID available channels corresponding to the RFID data in the network to obtain an available level of the RFID available channels includes:
s11, scanning the RFID available channel to acquire the existing signal strength of the RFID available channel; in the process of scanning the RFID available channel, the existing signal strength of the RFID available channel is obtained, namely whether the RFID available channel is occupied or whether the received interference signal is large is judged according to the existing signal strength. When the RFID available channel is occupied, the occupied signal of the RFID available channel is scanned, and the strength of the occupied signal is obtained, namely the strength corresponds to the existing signal strength. When the RFID available channel is interfered by an external signal, the RFID available channel is scanned to have an external interference signal, and the strength of the external interference signal is acquired and corresponds to the strength of the existing signal.
And S12, acquiring the available grade of the available RFID channel according to the existing signal strength, wherein the higher the existing signal strength is, the lower the available grade is. And after the existing signal strength corresponding to the RFID available channel is obtained, sequencing the RFID available channels according to the existing signal strength.
In an embodiment, the available RFID channels may be sorted according to the order of the strength of the existing signal, and the available levels of the available RFID channels are correspondingly set according to the order, that is, the available levels of the available RFID channels may be sorted from low to high according to the strength of the existing signal, where the higher the strength of the existing signal is, the lower the available level of the available RFID channel is, and the lower the existing signal is, the higher the available level of the available RFID channel is.
In another embodiment, the intensity range of the preset interference signal corresponding to the RFID data can be obtained according to the transmission requirement of the RFID data, and the corresponding available grade sequence is set according to the intensity range; and acquiring the available grade of the RFID available channel according to the existing signal strength and the strength range. The method comprises the steps of acquiring the requirement of the RFID data on a transmission channel based on the transmission requirement of the RFID data, and confirming the influence degree of the intensity range of the interference signal intensity of the channel when the RFID data is transmitted on the transmission quality of the RFID data. For example, the transmission quality of the RFID data is classified into a high level, a medium level, and a low level, and corresponds to a strength range of an interference signal when the transmission quality is highest, corresponds to a strength range of an interference signal when the transmission quality is at the medium level, and corresponds to a strength range of an interference signal when the transmission quality is at the lowest level. The output quality of the interference signal processing method is not limited to a plurality of levels of three levels, namely, the output quality of the interference signal processing method is not limited to a plurality of levels of high, medium and low levels, the intensity range of the corresponding interference signal is also a plurality of intensity ranges, the available level sequence of the corresponding channel is set according to the plurality of intensity ranges, namely, when the interference signal of the channel is in one intensity range, the interference signal corresponds to one available level, when the interference signal of the channel is in another intensity range, the interference signal of the channel corresponds to another available level, and the like, so that the sequence of the corresponding relation between the intensity range of the interference signal on the channel and the available level of the channel is obtained. Then, according to the existing signal strength corresponding to the acquired channel, the corresponding strength range is confirmed, that is, the available level corresponding to the strength range can be the available level of the channel according to the acquired available level. It can be understood that, when the available level of the channel is higher, the smaller the corresponding existing occupied signal is, and the higher the transmission quality of the channel is.
Optionally, in an embodiment, the first channel and the second channel are obtained according to the available level; the method comprises the following steps: selecting two RFID available channels with the highest available grade according to the available grade as a first channel and a second channel respectively; specifically, when the channel is selected, it may be sorted according to available rank, for example, when the available rank obtained is sorted according to the existing signal strength, it may obtain two channels with the minimum existing signal strength according to the sorting for data transmission.
Optionally, in an embodiment, any two available RFID channels corresponding to the available levels meeting the preset condition may also be acquired as the first channel and the second channel, respectively. That is, when the channel selection is performed, it may not select the channel with the highest available rank for data transmission, it may select the channel having no influence on the RFID data transmission quality for data transmission, for example, it may select two channels with a relatively high available rank for data transmission, although it is not the optimum available rank, the interference signal of the channel may be almost negligible with respect to the RFID data, and it has almost no influence on the RFID data transmission quality, and thus it may also perform data transmission as a priority choice. Meanwhile, when the available level of the channel is divided according to the transmission quality of the RFID data, there may be more than two channels, and then two channels may be arbitrarily selected in the available level for the transmission of the RFID data.
Optionally, synchronizing the first channel and the second channel comprises: the first channel and the second channel are synchronized by a timing setting. Specifically, the two channels selected for transmitting the RFID data can be synchronized by timing, so as to achieve synchronization of the two channels, ensure synchronization of data in RFID data transmission, and ensure data transmission quality.
Optionally, as shown in fig. 3, in an embodiment, splitting the RFID data according to a first preset rule, and transmitting the split data through a first channel and a second channel according to a second preset rule includes: a1, splitting the RFID data by taking a data frame as a unit; a2, transmitting one or more data frames through any one of the first channel and the second channel; a3, switching to another channel of the first channel and the second channel to transmit one or more data frames again after the transmission of any channel is finished; a4, after the transmission of another channel is finished, switching to any previous channel to transmit one or more adjacent data frames, and executing step A3. The specific process comprises the steps of analyzing and processing RFID data according to data frames to obtain data blocks taking the data frames as units, transmitting one or more data frames through any one of two channels to transmit one or more data frames, and switching another channel to transmit one or more data frames after the transmission of the one or more data frames by the channel to transmit the one or more data frames again. And after the other channel finishes the transmission of the one or more data frames, switching to the previous channel to transmit the one or more data frames later, and sequentially repeating the switching of the channels to alternately and repeatedly transmit the data frames so as to realize the transmission of the whole RFID data.
