However, the type of the display device 40 is not limited to the scope of the present invention.
In the embodiment of the present invention, the host 30 and the display device 40 are two independent devices, and are coupled to each other in a wired or wireless manner, and the host 30 can connect the measuring apparatus BT1-BTMThe transmitted measurement data is transmitted to the display device 40 for display. In another embodiment of the present invention, the host 30 has a display device 40 built therein, so that the measurement device BT can be used1-BTMThe transmitted measurement data is directly displayed on the display device 40. However, the arrangement of the host 30 and the display device 40The manner does not limit the scope of the present invention.
FIG. 2 is a flowchart of a data management method according to an embodiment of the invention, which can be executed by the data management system 100 to perform the following steps:
step 210: the host computer 30 selects one measuring device from the M measuring devices as a target measuring device; step 220 is performed.
Step 220: the host 30 sets a threshold value for determining the connection quality as an initial value; step 230 is performed.
Step 230: the host computer 30 determines whether the signal intensity of the target measuring device is higher than a threshold value; if yes, go to step 250; if not, go to step 240.
Step 240: the host computer 30 increases the critical value to an adjustment value which is not less than the initial value and not more than the upper limit value; step 230 is performed.
Step 250: the host 30 selects the first transceiver 10 as the primary transceiver; step 260 is performed.
Step 260: the host 30 sends a read data request to the target measurement device via the primary transceiver; step 270 is performed.
Step 270: the host computer 30 determines whether the primary transceiver can receive measurement data from the target measurement device within a predetermined period; if yes, go to step 320; if not, go to step 280.
Step 280: the host 30 determines that a connection interruption event occurs and releases the connection resources of the primary transceiver; step 290 is performed.
Step 290: the host 30 determines whether the primary transceiver has been connected to more than N of the M measurement devices; if yes, go to step 310; if not, go to step 300.
Step 300: the host computer 30 selects another measuring device from the M measuring devices as a target measuring device; step 230 is performed.
Step 310: the host 30 selects the second transceiver 20 as the primary transceiver; step 260 is performed.
Step 320: displaying the measurement data transmitted by the target measurement equipment; step 330 is performed.
Step 330: the host computer 30 determines whether or not continuous K measurement data have been received from the target measurement device; if yes, go to step 340; if not, go to step 300.
Step 340: the host 30 sets the threshold value as an initial value; step 300 is performed.
In steps 210 and 300, the host 30 may select one measuring device from the M measuring devices as a target measuring device. In an embodiment, a manager or an operator of the data management system 100 may manually issue a user command to request one or more specific measuring devices of the M measuring devices to report the measurement data, so that the host 30 may sequentially set the one or more specific measuring devices indicated by the user command as the target measuring devices. In another embodiment, the host 30 may request one or more specific measuring devices of the M measuring devices to report the measurement data periodically, at a specific time or randomly according to the program codes stored in the memory thereof, so that the host 30 can set the one or more specific measuring devices indicated by the program codes stored in the memory thereof as the target measuring devices. However, the manner in which the host computer 30 selects the target measurement device does not limit the scope of the present invention.
In the present invention, the steps 220, 230, 240, 330 and 340 are to ensure the overall connection quality between the measuring device and the transceiver. Before the host 30 sends a request for data to the target measurement device, the threshold value set as the initial value is used to evaluate the connection quality of the target measurement device in steps 220 and 230. When the signal strength of the target measuring device is not higher than the threshold value, the host computer 30 sets the threshold value to an adjustment value that is not smaller than the initial value and not larger than the upper limit value in step 240, and then performs step 230 to evaluate the on-line quality of the target measuring device by using the threshold value set as the adjustment value. When it is determined that K consecutive measurement data have been received from the target measurement device (K is an integer greater than 1) in step 330, the host 30 sets the threshold value to the initial value again in step 340. The design of the K value is determined by the designer according to the actual situation, and may be, for example, 2, 3, 4, etc., which are not described herein again.
In an embodiment of the present invention, the signal strength of the target measurement device may be a Received Signal Strength Indicator (RSSI) parameter, and a larger RSSI value indicates a better connection quality between the measurement device and the transceiver. However, the parameters used to evaluate the quality of the connection between the measuring device and the transceiver do not limit the scope of the present invention.
For example, assume that the host 30 first selects the measurement device BT in step 2101As the target measurement device, the threshold value is initially-95 dBm and the upper limit value is-82 dBm. If the measuring device BT1RSSI of less than-95 dBm, which may not successfully receive the read data request from the host 30, and the host 30 may not successfully receive the BT from the measuring device1The returned measurement data. Therefore, the host 30 increases the threshold to an adjusted value (e.g., -92dBm) that is not less than the initial value and not greater than the upper limit in step 240, i.e., the threshold is increased, and the increased threshold is still within an interval range, wherein the lower limit of the interval range is substantially the previous threshold and the upper limit of the interval range is not changed.
Assume that the host 30 then selects the measuring device BT in step 3002As a target measuring device, and a measuring device BT2RSSI of not less than-92 dBm, at which point the host may perform subsequent step 250; if the measuring device BT2Is less than-92 dBm, the host may repeat step 240 to set the threshold to the adjusted value (e.g., -89 dBm). In other words, when M measuring devices BT1-BTMWhen the overall signal strength is not good enough, the present invention will raise the threshold value in step 240, so that the host 30 will only send the data reading request to the target measurement device with higher RSSI. On the other hand, when M measuring devices BT1-BTMThe higher the success rate of transmitting measurement data when the overall signal strength is good. When it is determined in step 330 that consecutive K measurements have been successfully received from the target measurement device, the host computer may set the threshold value to an initial value in step 340.
When the signal strength of the target measuring device is determined to meet the standard (i.e., is higher than the threshold), the host 30 selects the first transceiver 10 as the primary transceiver in step 250, and sends a read data request to the target measuring device through the primary transceiver in step 260. When it is determined in step 270 that the primary transceiver can receive measurement data from the target measurement device within the predetermined period, the measurement data transmitted by the target measurement device may be displayed on the display device 40 in step 320.
When the connection between the primary transceiver and the target measurement device is not maintained for any reason, the measurement data sent by the target measurement device may be delayed or lost. In this situation, the present invention determines in step 270 that the primary transceiver is unable to receive measurement data from the target measurement device within a predetermined period of time. At this time, the host 30 determines that a connection interruption event occurs and releases the connection resources of the primary transceiver in step 280. In this way, the present invention can prevent the host 30 from continuously waiting for the response of the target measurement device, which results in the connection resources according to the first transceiver 10 being substantially occupied, but in practice, the data management system 100 does not respond and reduces the overall resource efficiency.
In step 290, if the host 30 determines that the primary transceiver is connected to more than N measuring devices (N is a positive integer less than M) of the M measuring devices, it represents that the target measuring device (e.g. measuring device BT) cannot be connected to the primary transceiver1) The successful reception of the measurement data may be caused by the host side, for example, the main transceiver (the first transceiver 10) is overloaded. In this case, the present invention proceeds to 310 to let the host 30 select the second transceiver 20 as the primary transceiver, and then proceeds to 260-280 again to attempt to send a read data request to the same target measurement device (e.g., the measurement device BT) via the other transceiver (the second transceiver 20)1)。
In step 290, if the host 30 determines that the primary transceiver is not connected to more than N of the M measuring devices, it represents that the target measuring device (e.g. measuring device BT) cannot be connected to the target measuring device1) The reason for successful reception of the measurement data may be caused by the measurement device, such as the target measurement device (measurement device BT)1) The wearer of (a) for this reason leaves the effective communication range of the primary transceiver (the first transceiver 10). In this case, the present invention performs 300 for the host 30 to select another measurement from the M measurement devicesDevice (e.g. measuring device BT)2) Serving as the target measuring device, step 230 is executed again to attempt to send the read data request to the other target measuring device (measuring device BT) through the same transceiver (first transceiver 10)2)。
In summary, the present invention can be applied to any data management system based on a wearable measurement device, such as a gymnasium where each member wears a measurement device to record the heart rate variation during exercise at any time. The data management method of the present invention will firstly ensure the connection quality between the target measurement device and the transceiver to meet the standard, and then send the read data request to the target measurement device. When the wearer of the target measuring device leaves the communication range due to reasons, the data management method can avoid the occupation of the connection resources to try to establish the connection with the target measuring device outside the communication range. Therefore, the invention can improve the resource efficiency and the connection quality of the data management system.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
