[0024] Embodiment 1

[0025] Figure 1 A flowchart of a short-range wireless communication method is provided for Embodiment 1 of the present invention. This embodiment is applicable to the scenario where data collection results are sent according to a certain transmission power while ensuring a balance between the reliability of wireless transmission and low power consumption. The method can be executed by a short-range wireless communication device, which can be implemented in the form of hardware and / or software.

[0026] Correspondingly, such as Figure 1 As shown, the method includes:

[0027] S110, acquiring data collection results in real time, and storing the data collection results in a cache.

[0028] The data collection result may be a result of data collection obtained by a data collection device performing a data collection operation on data within a period of time. The cache may be a cache capable of storing data collection results.

[0029] Generally speaking, a cache may refer to a cache with a faster access speed than a general random access memory. In this embodiment, the cache may be used to synchronize data acquisition time and wireless transmission speed, and the wireless transmission power may be adjusted by obtaining the amount of data in the cache.

[0030] Optionally, data collection results are acquired in real time and stored in a cache, including: whenever a data collection condition is met, a set number of data collection operations are performed, and each collected data collection result is stored in the cache.

[0031] The data collection condition can be used in a data collection device to detect the data collection condition, and when the data collection condition is met, a data collection operation is performed. The set number of times can be a preset number of collection times performed by the data collection device.

[0032] In this embodiment, each time the data collection condition is met, the data collection device needs to collect data multiple times until the number of data collection times reaches the set number. Further, each time data collection is performed, it is necessary to determine whether the current number of data collection times reaches the set number of data collection devices, and perform corresponding processing operations according to the determination result.

[0033] Optionally, whenever the data collection conditions are met, a set number of data collection operations are performed, and the data collection results collected each time are stored in the cache respectively, including: periodically obtaining a data collection flag; when the data collection flag is obtained, performing a data collection operation, and after the collection is completed, storing the collected data collection results in the cache; updating the current number of data collection times through a counter; judging whether the current number of data collection times reaches the set number, and if so, determining that the set number of data collection operations are completed; if not, returning to perform a data collection operation, and after the collection is completed, storing the collected data collection results in the cache, until the current number of data collection times reaches the set number.

[0034] The data collection mark may be a mark that triggers the data collection device to collect data.

[0035] Specifically, the data acquisition device periodically detects the data acquisition mark. Assuming that the data acquisition mark is detected at the current moment, the data acquisition device performs data acquisition operations. If the data acquisition mark is not detected at the current moment, the data acquisition device waits for the arrival of the next cycle moment and then performs data acquisition mark detection and acquisition operations.

[0036] The current data collection times may be the times of executing data collection in the current cycle counted by a timer.

[0037] For example, assume that the preset number of times of the data acquisition device is 10 times, and the initial value of the counter is 0. When the data acquisition device obtains the data acquisition flag, it needs to perform a data acquisition operation, and after the acquisition is completed, the collected data acquisition results are stored in the cache. Further, the data acquisition device needs to update the current data acquisition times through the counter, that is, the current data acquisition times is 1.

[0038] Next, it is necessary to determine whether the current data collection times (value is 1) has reached the set times 10. Since the current data collection times has not reached the set times, the data collection operation will continue until the current data collection times reaches the set times. That is, when the current data collection times is 10, it is determined that the set times of data collection operations have been completed.

[0039] The advantage of this setting is that the current data collection times are updated through the timer, and the current data collection times are compared with the preset times to determine whether to continue the data collection operation. This allows data collection to be performed more reasonably and accurately. In addition, the data collection flag is obtained periodically, and whether to start data collection is determined based on whether the data collection flag is obtained. This can improve the reliability of data collection.

[0040] Optionally, after the collection is completed, the collected data collection results are stored in the cache, and it also includes: determining whether the current cached data volume in the cache exceeds a preset overflow data volume threshold, and if so, clearing the cache.

[0041] The current cache data volume may describe the amount of cached data in the cache. The larger the current cache data volume, the higher the wireless transmission rate needs to be to reduce the data pressure of the cache. Conversely, the wireless transmission rate needs to be reduced. The overflow data volume threshold may indicate that the amount of buffered data in the current cache is too much, resulting in an overflow of the cache data volume.

[0042] In this embodiment, it is assumed that the preset overflow data volume threshold is T. After the data acquisition device completes data acquisition, the acquired data acquisition results are stored in the cache memory, and then the current cache data volume is determined to be M.

[0043] Furthermore, the data acquisition device needs to determine whether the current cached data volume M in the cache exceeds the preset overflow data volume threshold T. Assuming M≤T, it can be determined that the current cached data volume does not exceed the preset overflow data volume threshold, so the data acquisition operation will continue. Assuming M>T, it can be determined that the current cached data volume has exceeded the preset overflow data volume threshold, and the data acquisition device clears the cache.

[0044] The advantage of this setting is that by judging the relationship between the current cache data volume of the cache and the preset overflow data volume threshold, the decision on whether to perform data collection and clear the cache can be made in one step, thereby more accurately determining the wireless transmission power and improving the reliability of wireless data transmission.

[0045] S120: Determine a current radio frequency transmission power value according to the real-time cache data amount in the cache.

[0046] The larger the cache data volume, the higher the RF transmission power value.

[0047] The cached data volume may be the size of the data volume cached in the cache memory. The current radio frequency transmission power value may be the size of the radio frequency transmission power used when the data acquisition device transmits data.

[0048] Specifically, the larger the amount of cached data in the cache, the greater the data pressure of the cache, and the higher the data transmission speed needs to be. The smaller the amount of cached data in the cache, the smaller the data pressure of the cache, and the lower the data transmission speed needs to be.

[0049] In this embodiment, the current RF transmission power value is determined by the amount of cached data, which can avoid power consumption waste caused by sending too little data and overflow of data in the cache due to too much data but not sending it in time, causing data failure problems.

[0050] S130: According to the current radio frequency transmission power value, the data collection result is obtained from the high-speed buffer in real time and sent to a target receiving device over a short distance.

[0051] In this embodiment, the current radio frequency transmission power value is determined according to the amount of buffered data, and the data collection result is sent over a short distance according to the determined current radio frequency transmission power value to the target receiving device.

[0052] The technical solution of the embodiment of the present invention obtains data acquisition results in real time and stores the data acquisition results in a cache; determines the current RF transmission power value according to the real-time cached data volume in the cache; obtains the data acquisition results from the cache in real time and transmits them to the target receiving device over a short distance according to the current RF transmission power value. It is possible to adjust the corresponding transmission power according to the data volume of the data acquisition results, so that the data acquisition results can be sent more reasonably according to the corresponding transmission power, achieving a balance between the reliability of wireless transmission and low power consumption, and effectively adjusting the power consumption problem.

[0053] Embodiment 2

[0054] Figure 2 A flowchart of another short-range wireless communication method provided in Embodiment 2 of the present invention. This embodiment is refined based on the above embodiments. In this embodiment, the current RF transmission power value is determined based on the real-time cache data amount in the cache memory and further refined.

[0055] Correspondingly, such as Figure 2 As shown, the method includes:

[0056] S210, acquiring data collection results in real time, and storing the data collection results in a cache.

[0057] S220. Whenever a transmit power adjustment condition is met, obtain a current cache data amount in the cache.

[0058] Among them, the transmission power adjustment condition can be used for the power adjustment device to determine whether the transmission power adjustment condition is met. If it is met, the power adjustment device needs to adjust the transmission power. If it is not met, there is no need to perform the transmission power adjustment operation.

[0059] S230: Compare the current cache data volume with at least one preset data volume threshold to obtain a comparison result.

[0060] The data volume threshold may be a threshold describing the size of the data volume in the high-speed buffer, and the data volume threshold may include a first data volume threshold, a second data volume threshold, and a third data volume threshold. The comparison result may be a result obtained by comparing the current cache data volume with the data volume threshold.

[0061] Optionally, the current cached data volume is compared with at least one preset data volume threshold to obtain a comparison result, including: the preset data volume threshold includes: a first data volume threshold, a second data volume threshold and a third data volume threshold; if it is determined that the current cached data volume is less than the first data volume threshold, a first comparison result is obtained; if it is determined that the current cached data volume is greater than or equal to the first data volume threshold and less than the second data volume threshold, a second comparison result is obtained; if it is determined that the current cached data volume is greater than or equal to the second data volume threshold and less than the third data volume threshold, a third comparison result is obtained.

[0062] Among them, the first data volume threshold may be the smallest data volume threshold among the first data volume threshold, the second data volume threshold and the third data volume threshold, reflecting that the current data volume pressure of the cache is not too large. The first comparison result may be the result obtained by comparing the current cache data volume with the first data volume threshold. The second data volume threshold may be the middle data volume threshold among the first data volume threshold, the second data volume threshold and the third data volume threshold. The second comparison result may be the result obtained by comparing the current cache data volume with the first data volume threshold and the second data volume threshold. The third data volume threshold may be the largest data volume threshold among the first data volume threshold, the second data volume threshold and the third data volume threshold, reflecting that the current data volume pressure of the cache is relatively large. The third comparison result may be the result obtained by comparing the current cache data volume with the second data volume threshold and the third data volume threshold.

[0063] Exemplarily, assuming that the first data volume threshold is Th 1 , the second data volume threshold is Th 2 and the third data volume threshold is Th 3 , and the current cached data volume is A.

[0064] The current cached data volume A needs to be compared with the data volume threshold. Specifically, assuming A < Th 1 , it can be determined that the current cache data volume A is less than the first data volume threshold Th 1 , then we get the first comparison result Z 1 .

[0065] Furthermore, assuming that Th 1 ≤A<Th 2 , it can be determined that the current cache data volume A is greater than or equal to the first data volume threshold Th 1 , and is less than the second data volume threshold Th 2 , then the second comparison result Z is obtained 2 .

[0066] Accordingly, assuming that Th 2 ≤A<Th3 , it can be determined that the current cache data volume A is greater than or equal to the second data volume threshold Th 2 , and is less than the third data volume threshold Th 3 , then the third comparison result Z is obtained 3 .

[0067] S240: If a target transmit power adjustment level matching the current cache data amount is successfully acquired according to the comparison result, a current radio frequency transmit power value corresponding to the target transmit power adjustment level is acquired.

[0068] The target transmit power adjustment level may be a level describing the transmit power. Specifically, each comparison result may correspond to a transmit power adjustment level.

[0069] In this embodiment, it is assumed that the first comparison result corresponds to a first level of transmission power adjustment; the second comparison result corresponds to a second level of transmission power adjustment; and the third comparison result corresponds to a third level of transmission power adjustment.

[0070] Exemplarily, assume that the current RF transmit power value corresponding to the first level of transmit power adjustment is 0.036W; the current RF transmit power value corresponding to the second level of transmit power adjustment is 0.36W; and the current RF transmit power value corresponding to the third level of transmit power adjustment is 1W.

[0071] Further, assuming that the first comparison result Z is currently obtained 1 According to the first comparison result, the first level of transmission power adjustment matching the current cache data volume is successfully obtained, and then it can be determined that the current RF transmission power value is 0.036W.

[0072] Optionally, if it is determined that the current cached data volume is greater than or equal to the second data volume threshold and less than the third data volume threshold, after obtaining the third comparison result, it also includes: if it is determined according to the third comparison result that the current cached data volume in the cache exceeds the preset overflow data volume threshold, the most recently used RF transmission power value is used as the current RF transmission power value.

[0073] Continuing from the previous example, the preset overflow data volume threshold is T. Assume that Th 3 ≤A, requires the third comparison result Z 3 To determine whether the current cached data volume A in the cache exceeds the preset overflow data volume threshold T. If so, it is necessary to disconnect the transmission power device from the data acquisition device, and the data acquisition device clears the high-speed buffer and uses the most recently used RF transmission power value as the current RF transmission power value.

[0074] In addition, assuming that the current cache data volume A in the cache does not exceed the preset overflow data volume threshold T, according to the third comparison result Z 3 To determine the current RF transmit power value.

[0075] The advantage of this setting is that when it is detected that the current cached data volume in the cache exceeds the preset overflow data volume threshold, it is necessary to disconnect the connection with the data acquisition device in time, and the data acquisition device can clear the high-speed buffer in time, which can improve the reliability of RF power transmission and avoid waste of resources.

[0076] S250: According to the current radio frequency transmission power value, the data collection result is obtained from the high-speed buffer in real time and sent to a target receiving device over a short distance.

[0077] The technical solution of the embodiment of the present invention is to obtain the data collection results in real time and store the data collection results in a cache; whenever the transmission power adjustment condition is met, the current cache data volume in the cache is obtained; the current cache data volume is compared with at least one preset data volume threshold to obtain a comparison result; if the target transmission power adjustment level matching the current cache data volume is successfully obtained according to the comparison result, the current RF transmission power value corresponding to the target transmission power adjustment level is obtained; according to the current RF transmission power value, the data collection results are obtained from the cache in real time and sent to the target receiving device over a short distance. It is realized that the corresponding transmission power adjustment can be performed according to the data volume of the data collection results, so that the data collection results can be sent more reasonably according to the corresponding transmission power, and the reliability of wireless transmission and low power consumption are balanced, the power consumption problem is effectively adjusted, and the phenomenon of resource waste caused by resource occupation can also be avoided.
