Data processing method and mirror server for low-power wireless personal area network system

A mirror server for a low-power wireless personal area network (WPAN) system including an electronic device, the mirror server comprising:

• a memory including a plurality of memory blocks;
• a communication circuit communicatively connected to the electronic equipment, wherein the communication circuit is configured to receive sensing data generated and transmitted by the electronic device at time intervals, and store the sensing data in one of a plurality of memory blocks of the memory, wherein the one of the plurality of memory blocks is indexed as a first time segment, the plurality of memory blocks further includes N memory blocks that are indexed from a second time segment of a previous unit time before the first time segment to an (N+1)th time segment of an Nth previous unit time before the first time segment, N is an integer greater than 1, and the electronic device generates, according to the time intervals, a last data record of the sensing data of the first time segment at a specific time;
• and
• a processing circuit configured to:
• determine whether or not the last data record of the sensing data of the first time segment is received in a fault-tolerant time segment between the first time segment and a next time segment;
• and
• in response to determining that the last data record of the sensing data of the first time segment is received in the fault-tolerant time segment, trigger a rollover mechanism to:
• move and store the sensing data stored in a memory block that is indexed as a (k+1)th time segment of a kth previous unit time before the first time segment of the plurality of memory blocks into a memory block that is indexed as a (k+2)th time segment of a (k+1)th previous unit time before the first time segment of the plurality of memory;
• and
• move and store the sensing data stored in the memory block that is indexed as the first time segment into the memory block that is indexed as the second time segment, wherein k is an integer from N−1 to 1.
