The utility model discloses a debugging meter reading system for collective meter reading of electric energy meters. The system comprises a 485 communication trunk, a plurality of 485 communication branches and a plurality of electric energy meters. The 485 communication branches are connected to the 485 communication trunk in an electric communication manner. The electric energy meters are connected to the corresponding 485 communication branches one by one in an electric communication manner. The system further comprises a safety wire clamp and a meter reading terminal. One end of the safe wire clamp is detachably connected to the 485 communication trunk in an electric communication manner, and the other end of the safe wire clamp is connected to the meter reading terminal in an electric communication manner. The communication line of the safety wire clamp is provided with an RS232 serial port connector. The meter reading terminal is disposed on the 485 communication trunk through the safety wire clamp, so as to timely test wire connection conditions of a circuit under test in the 485 communication trunk, and rapidly detect wire connection conditions of an electric energy meter collective meter reading system. The system is advantaged by being simple to find out problems, portable, and easy to understand and learn. The system is further used for rapid meter reading of an electric energy meter by operating personnel at a short range.
