Referring to fig. 1 to 3, fig. 1 is an exploded perspective view of a broadband power carrier equipment maintenance terminal according to the present invention. Fig. 2 is a perspective view of the broadband power carrier device maintenance terminal of the present invention. Fig. 3 is a perspective view of the broadband power line carrier device maintenance terminal according to the present invention. The utility model provides a broadband power line carrier equipment maintains terminal 10, it includes: rear shell 1, face-piece 2, mainboard 3, HPLC module 4, coupling antenna 5 and mounting bracket 6. Wherein, the rear shell 1 and the face shell 2 are mutually matched to form an accommodating cavity; the motherboard 3, the HPLC module 4, the coupling antenna 5 and the mounting rack 6 are all mounted in the receiving cavity. HPLC module 4 and coupling antenna 5 are mounted to motherboard 3 by means of mounting bracket 6.
For example, the main board 3 includes functional modules such as a processor and a display screen. The coupling antenna 5 is in a wire winding shape and is made into a multi-turn circular coil by using an enameled wire. The side of the mounting frame 6 facing the rear housing 1 is provided with a support slot 65 for cooperation with the coupling antenna 5. By means of this support slot 65, the coupling antenna 5 is electrically connected to the HPLC module 4, for example: the HPLC module 4 is provided with a connector protruding through the bottom of the supporting slot 65, and electrically connected to the coil on the coupling antenna 5.
The rear case 1 is provided with a power line coupling mating part 15 corresponding to the mounting position of the coupling antenna 5.

HPLC module 4 provides broadband power carrier communication functionality. HPLC module 4 and mainboard 3 electric connection adopt the serial ports to communicate between HPLC module 4 and the mainboard 3, and HPLC module 4 is controlled by mainboard 3. The information received by the HPLC module 4 through the power line is sent to the mainboard 3; the information sent out by the HPLC module 4 through the power line comes from the main board 3. The HPLC module 4 is coupled to the power line by means of a coupling antenna 5 and is capable of receiving/transmitting, related to communication signals.
The application of the maintenance terminal 10 is various, for example, the maintenance terminal 10 is suitable for an application scenario of a power consumption information collection system. The main technical indices of HPLC module 4 are: modulation scheme, OFDM (Orthogonal frequency division Multiplexing); working frequency band, 0.7-3 MHz; data communication rate, 55 kbps-1 Mbps; under the emission power spectral density and standard test environment, the frequency band is not more than-45 dBm/Hz in the working frequency band and not more than-75 dBm/Hz outside the working frequency band; the attenuation resistance and the in-band emission power spectral density are not less than 85dB under the condition of-45 dBm/Hz; signal coupling mode, single-phase or three-phase mutual inductance coupling; powerline channel, 220VAV ± 30% 50 Hz. The HPLC module 4 couples the transmission signal through the coupling antenna according to the energy space through the coupling antenna 5, so that the space radiates outwards to allow the HPLC unit of the electric energy meter, the collector or the concentrator to receive an effective data signal, and simultaneously receives data information of an HPLC space wireless signal sent by the electric energy meter, the collector or the concentrator through the power line through the coupling antenna 5, thereby completing wireless communication of high-speed carrier interconnection.
