The invention discloses a remote-concentrated meter reading system for residents. the remote-concentrated meter reading system is composed of a main station, an acquisition terminal and an electricity meter, wherein the main station communicates by a wireless public network and the acquisition terminal; the acquisition terminal and the electricity meter are connected through a bus mode; a data receiving device and a data sending device are arranged on the bus; and the data receiving device is provided with a power adapter. Improved designs comprise a sampling circuit, a switching circuit and a switching reset circuit, wherein the bus accesses to the data receiving device through the sampling circuit; and the power adapter accesses to a circuit board in the data receiving device through the switching circuit. Various works such as remote meter reading, load monitoring and the like are effectively carried out by utilizing technical requirements for a low-voltage acquisition system and various functions of the terminal, a concentrator, a wireless collector and a carrier collector, thereby greatly reducing pressure of low-voltage meter reading work. The application of the low-voltage remote meter reading system can effectively guide and ensure smooth implementation of various indicators of the low-voltage electricity consumption management.
