One point.Point B (200,0) is exactly the upper drop of zero passage detection signal along corresponding one of point.In specific implementation, step
S10 and S11 can be regarded as transformer side control execution.Firstly, in power line carrier communication network, into a certain range
Power carrier communication module send broadcast singal, it should be noted that for send broadcast singal when require, it is necessary to
It is sent in the rising edge or failing edge of the zero passage detection signal of electric power signal.When power carrier communication module receives broadcast singal
Afterwards, wiring correct information or wiring error information are sent to transformer side control according to receiving broadcast singal.If transformation
When device side controller receives the wiring correct information of power carrier communication module transmission, it is determined that power carrier communication module
The wiring of power line is correct, when receiving the wiring error information of power carrier communication module transmission, determines that power carrier is logical
Believe the wiring error of the power line of module.Due to having multiple power carrier communication modules, it is possible to transformer in an area Ge Tai
Side controller can directly transmit broadcast singal to whole power carrier communication modules, it is also possible to which needs receive broadcast letter
Number power carrier communication module to other power carrier communication modules forward broadcast singal.It either directly transmits or indirect
Broadcast singal is sent, as long as power carrier communication module receives broadcast singal.
It is understood that forwarding broadcast singal, then the power line carrier, PLC mould if necessary to power carrier communication module
Block forward broadcast singal at the time of necessarily with transformer side control forward broadcast singal at the time of it is consistent, i.e., if transformer
In the rising edge of the zero passage detection signal of electric power signal, then power carrier communication module at the time of side controller forwards broadcast singal
