The invention relates to a
broadband power line carrier communication module seven-stage
relay communication testing
system, which comprises an
alternating current filter, a power supply module, a
broadband power carrier centralized controller, a coupler, seven fixed attenuators, seven base table units and a seven-stage shield box, wherein the seven-stage shield box is provided with fourteen cells, the power supply module is arranged inside the first
cell of the seven-stage shield box, the fixed attenuator and the base table unit are arranged inside the second
cell, the base table units are respectively arranged in the fourth
cell, the sixth cell, the eighth cell, the tenth cell, the twelfth cell and the fourteen cell, the fixed attenuators re respectively arranged in the third cell, the fifth cell, the seventh cell, the ninth cell, the eleventh cell and the thirteenth cell, each base table unit is respectively connected with the same stage fixed attenuator and the next stage fixed attenuator, the power supply module and each base table unit are sequentially connected through power supply lines, and the
broadband power carrier centralized controller is connected with one of the fixed attenuators through the coupler. With the broadband power line carrier communication module seven-stage
relay communication testing
system of the present invention, the broadband power line carrier communication module seven-stage
relay communication test can be achieved, the integrity is high, the wiring is convenient, and the operation is flexible and simple.
