The invention relates to the technical field of
signal transmission, in particular to a centralized meter reading method, an acquisition terminal and a fusion terminal. The method comprises the following steps: after establishing
Bluetooth communication connection with a plurality of
electric energy meters, dividing the plurality of
electric energy meters into different
communication quality groups based on a
joint evaluation result obtained by measured
Bluetooth signal strength and communication error rate of each
electric energy meter, and configuring adaptive communication configuration parameters for each group; according to the communication configuration parameters, a differential broadcast strategy is adopted to synchronously send a meter reading instruction to each electric energy meter, and power utilization data is received in parallel; and in response to a
polling request of the fusion terminal, sending the cached
power consumption data to the fusion terminal. By jointly evaluating the
Bluetooth signal strength and the communication error rate, dynamically configuring the communication configuration parameters and implementing the differentiated broadcast strategy, the
concurrency and reliability of meter reading in a high-
noise environment can be improved, the communication conflict and
retransmission rate are effectively reduced, and the
data acquisition efficiency and the overall stability of centralized meter reading are improved.
