Problems solved by technology
The working status of the transmission lines in these large buildings, whether the transmission lines are connected to households, whether the neutral and live wires are connected in reverse, etc., have plagued people’s power quality. At present, the traditional detection of electric energy meters connected to households usually needs to be judged by pulling the switch. Judging whether the wiring is correct according to the on and off of the lighting lamp, the pull-up inspection technology is backward, the efficiency is low, and it requires the cooperation of multiple people, and it is even more troublesome for high floors. The entire floor was cut off, seriously affecting the quality of electricity for users

Embodiment Construction
[0024] The technical solutions of the present invention will be described in further detail below through specific implementation methods.
[0025] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a meter serial connection detection device includes a signal providing host and a signal feedback slave, the signal providing host is connected to the input end of the transmission line during detection, and the signal feedback slave is connected to the output of the transmission line terminal, such as the socket in the user's room; at the same time, purposely cut off the power for the user who needs to be detected to ensure the uninterrupted power consumption of other users, which not only meets the needs of transmission line detection, but also meets the power consumption requirements of users.
[0026] The signal supply host includes a host MCU and a host keyboard, a host communication module, a host display, and a host power supply that are respectively connecte...

The invention provides a meter serial connection detection device, which includes a signal supply host and a signal feedback slave, the signal supply host includes at least one signal output circuit, and the input terminals of different user transmission lines are connected through the signal output circuit , the signal feedback slave includes a signal feedback circuit, and the signal feedback slave is sequentially connected to output ends of power transmission lines of users in different rooms to detect the working status of the power transmission lines. The present invention also provides a detection method based on the electric meter serial connection detection device. The signal providing host and the signal feedback slave communicate with each other, so as to realize the detection of the working state of the user's power transmission line and avoid the occurrence of power transmission lines. Cross-connection of households, reverse connection of zero and live wires, etc.
Description
technical field [0001] The invention relates to a detection device and a detection method for the working state of a power transmission line, in particular, to a detection device and a detection method for the serial connection of electric meters. Background technique [0002] With the acceleration of the urbanization process, large buildings such as high-rise residential buildings and high-rise office buildings are increasing day by day, and the problem of electricity consumption is the main problem of people's life. The working status of the transmission lines in these large buildings, whether the transmission lines are connected to households, whether the neutral and live wires are connected in reverse, etc., have plagued people’s power quality. At present, the traditional detection of electric energy meters connected to households usually needs to be judged by pulling the switch. Judging whether the wiring is correct according to the on and off of the lighting lamp, the ...
