DETAILED DESCRIPTION

[0018] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0019] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] See also Figure 1 , Figure 1 A schematic diagram of a flow chart of a short-range wireless transmission method provided in an embodiment of the present application, such as Figure 1 As shown, the short-range wireless transmission method provided in the embodiment of the present application includes steps S1 to S5.

[0021] Step S1: Acquire data to be transmitted, and determine the data volume of the data to be transmitted.

[0022] The data to be transmitted includes but is not limited to data collected by sensors, control instructions generated by a central control system, data information obtained from the cloud, and data information input manually, and the data volume is the total bit value of the data to be transmitted. Specifically, the data to be transmitted is subjected to bit value analysis by a preset data analysis module to determine the bit value of the data to be transmitted.

[0023] Step S2: obtaining current channel state information through a preset channel detection device; wherein the channel state information includes signal power, noise power and bandwidth of multiple channels.

[0024] The channel detection device may be a spectrum analyzer or a software defined radio (SDR) device.

[0025] Step S3: for each of the channels, determine the transmission rate of the channel based on the signal power, noise power and bandwidth of the channel.

[0026] Specifically, the transmission rate of the channel is determined using the Shannon-Hartley theorem.

[0027] Step S4: Determine the short-range transmission rate of the data to be transmitted based on the data volume.

[0028] Specifically, the short-range transmission rate is obtained by dividing the data volume by a preset short-range transmission time threshold. It can be understood that in order to ensure the timeliness of short-range transmission, this embodiment sets a short-range transmission time threshold for short-range transmission.

[0029] Step S5: Determine whether the maximum transmission rate among the transmission rates is greater than the short-range transmission rate.

[0030] Step S6: If not, transmit the data to be transmitted to the receiving end based on a preset multi-channel transmission method.

[0031] Specifically, step S6 includes the following steps: Acquire a historical channel transmission rate information set connected to the current moment and within a preset time period after the current moment in the database; the historical channel transmission rate information set includes a plurality of historical transmission rate curve information of each of the channels within the preset time period, and each of the historical transmission rate curve information includes a plurality of historical transmission rate curves; the duration corresponding to the preset time period is the short-range transmission time threshold; Determine a minimum transmission rate among all transmission rates corresponding to all the historical transmission rate curves; Determine the amount of transmission data corresponding to the minimum transmission rate; specifically, obtain the amount of transmission data by multiplying the minimum transmission rate by the short-range transmission time threshold; The data to be transmitted is segmented based on the data amount and the transmission data amount to obtain a plurality of data blocks corresponding to the data to be transmitted, and the data blocks are arranged in sequence based on the positions of the data blocks in the data to be transmitted to obtain a data block sequence; wherein, when the ratio of the data amount to the transmission data amount is an integer, the number of the data blocks is the ratio of the data amount to the transmission data amount, and the data amount of each of the data blocks is the transmission data amount; when the ratio of the data amount to the transmission data amount is a decimal, the number of the data blocks is an integer adjacent to the ratio and greater than the ratio, for example, if the ratio is 3.3, the number of the data blocks is 4, and the data amount of each of the data blocks shall not be greater than the transmission data amount; For each of the data blocks, marking the sequence number of the data block in the data block sequence on the data block to obtain a marked data block; determining a plurality of target channels based on the number of the data blocks and the historical channel transmission rate information set; The data to be transmitted is transmitted to the receiving end through the multiple target channels. Specifically, each of the marked data blocks is transmitted to the receiving end through different target channels. After receiving each of the marked data blocks, the receiving end splices each of the data blocks based on the serial numbers marked on each of the marked data blocks to obtain the data to be transmitted.

[0032] It can be understood that the above-mentioned method of transmitting the data to be transmitted to the receiving end based on a preset multi-channel transmission method, by determining the amount of transmission data corresponding to the minimum transmission rate, and segmenting the data to be transmitted based on the data amount and the transmission data amount, obtains multiple data blocks corresponding to the data to be transmitted and subsequent steps, which can improve the effectiveness of transmitting each data block to the receiving end, and help prevent delays in short-range wireless transmission while ensuring the stability of data transmission.

[0033] Wherein, determining a plurality of target channels based on the number of the data blocks and the historical channel transmission rate information set comprises the following steps: For each of the channels, determining a target number corresponding to the channel based on the historical transmission rate curve information corresponding to the channel; wherein the target number is the minimum transmission rate among all transmission rates corresponding to all historical transmission rate curves in the historical transmission rate curve information corresponding to the channel; Arranging the channels in sequence based on the target numbers corresponding to the channels to obtain a channel sequence; wherein the target numbers corresponding to the channels in the channel sequence decrease in sequence; A plurality of target channels are sequentially selected from the channel sequence; wherein the number of the target channels is consistent with the number of the data blocks.

[0034] It can be understood that the above-mentioned method of determining multiple target channels based on the number of data blocks and the historical channel transmission rate information set, determines that the transmission rate of each target channel within the preset time period is not less than the minimum transmission rate. Since the data amount of each data block is not greater than the transmission data amount corresponding to the minimum transmission rate, even if the transmission rate of each target channel within the preset time period is the minimum transmission rate, each target channel can smoothly transmit each marked data block to the receiving end. In fact, the transmission rate of each target channel within the preset time period is not less than the minimum transmission rate. Therefore, each target channel determined by the above method can ensure that each marked data block is transmitted to the receiving end.

[0035] The method provided in this embodiment ensures the data transmission rate while ensuring the stability of data transmission, thereby preventing the delay of short-range wireless transmission.

[0036] In some embodiments, after determining whether the maximum transmission rate among the transmission rates is greater than the short-range transmission rate, the method further comprises the following steps: If so, determining that the channel corresponding to the maximum transmission rate is the transmission channel; Acquire a historical channel transmission rate information set connected to the current moment and within a preset time period after the current moment in a database; the historical channel transmission rate information set includes a plurality of historical transmission rate curve information of each of the channels within the preset time period, and each of the historical transmission rate curve information includes a plurality of historical transmission rate curves; Based on the historical channel transmission rate information set, determining whether there is a channel with a transmission rate greater than the short-range transmission rate in real time within the preset time period; If yes, the data to be transmitted is sent to the receiving end through the transmission channel; it can be understood that if there is a channel with a transmission rate greater than the short-range transmission rate in real time within the preset time period, it helps to ensure the transmission rate of the data to be transmitted during the transmission process and prevent transmission delay; In the process of sending the data to be transmitted to the receiving end, the transmission channel is monitored in real time, and when the transmission rate of the transmission channel is lower than the short-range transmission rate, the transmission channel of the data to be transmitted is switched to the transmission channel with the highest transmission rate through a preset fast switching algorithm; this step is iterated until the data to be transmitted is transmitted to the receiving end; If not, the data to be transmitted is transmitted to the receiving end based on a preset multi-channel transmission method; it should be noted that the method of transmitting the data to be transmitted to the receiving end based on a preset multi-channel transmission method has been introduced in detail above and will not be repeated here.

[0037] Wherein, judging whether there exists in real time a channel having a transmission rate greater than the short-range transmission rate within the preset time period based on the historical channel transmission rate information set includes: Determine a minimum transmission rate among all transmission rates corresponding to all the historical transmission rate curves; comparing the minimum transmission rate to the short range transmission rate; If the minimum transmission rate is greater than the short-range transmission rate, determining that there exists in real time within the preset time period a channel whose transmission rate is greater than the short-range transmission rate; If the minimum transmission rate is not greater than the short-range transmission rate, it is determined that no channel having a transmission rate greater than the short-range transmission rate exists in real time within the preset time period.

[0038] The method provided in this embodiment ensures the stability and timeliness of the data to be transmitted when it is transmitted as a whole without segmenting the data to be transmitted, and can effectively prevent the occurrence of short-range wireless transmission delay when the data to be transmitted is transmitted as a whole.
