In the prior art, one centralized meter reading terminal device needs to manage dozens to hundreds of resident user electric meters in one transformer, and needs to collect multiple items of data of each user electric meter every day. At present, there are two main methods for downlink meter reading of a centralized meter reading system: the first is that the concentrator directly reads each ammeter through a power line carrier or a micro-power wireless module; secondly, in order to avoid installing a power line carrier or micropower wireless module for each electric meter, a collector is added in the meter box, namely, the concentrator wirelessly transmits data to the collector through the power line carrier or micropower, and the collector then transparently transmits the data to a certain electric meter through 485. The two methods have no essential difference in reading speed and reading effect, but the second method can reduce carrier modules on a plurality of electric meters by a collector, thereby reducing the cost. However, the above-mentioned method for reading data of an electric meter by using a centralized reading system is mainly a single-data-item question-answer mode, which requires multiple interactive processes for reading multiple data items of an electric meter, thus wasting time and increasing channel occupation, and the whole reading system has only one carrier or wireless channel, and all data of hundreds of electric meters need to be read from the channel, and only one data can be continuously read, so that the reading rate is very low, the occupation of the carrier or wireless channel is very frequent, and the working efficiency of the whole reading system is very low.
Assuming that the number of the electric meters in the region is 400, each electric meter collects 9 data items, reading of each data item requires two times of communication, namely one sending and one receiving, and the number of times of communication required for reading the data of the 400 electric meters is as follows: 2 times 9 times 400 times 7200 times, and the average time taken for each communication is about 4 seconds, the time taken to read the 400 meter data is 7200 times 4 seconds, 28800 seconds, 480 minutes, and 8 hours.
