Abstract
The invention discloses a power cable with high-frequency communication capability, belongs to the technical field of power cables, and aims to provide a power cable with high-frequency communication capability, which has no interference on a communication cable. The invention adopts the technical scheme as follows: the power cable comprises a power copper core and a coaxial cable, wherein the power copper core and the coaxial cable are packaged in the same one power cable. According to the invention, the coaxial cable is adopted to achieve communication in which the base-band transmission is eliminated, i.e. the transmission is not performed at a low frequency, and the frequency band of communication is moved to a high range by the carrier adjustment method, as a result, the interference of the power cable on the communication cable is eliminated, the reliability is improved, and the power cable requirement for the integrated communication cable is lowered, for example, the power cable can not be shielded. The invention is applied to the field of underground coal mines and the like.
Description
Technical field
The present invention possesses the power cable of HF communication ability, belongs to the power cable technical field.
Background technology
Present power cable normally is encapsulated in the four-core copper cash in the cable, in order to satisfy the needs of communication, also can encapsulate several communication copper cash usually; The main distinction of communication copper cash and power copper cash is thickness, so power line provides energy thicker, the communication copper cash is then thinner; The power of main equipment is increasing at present, and all uses converter technology, causes power cable bigger to the interference ratio of telecommunication cable; Even power copper core is added shielding with the copper core of communicating by letter, effect is also very poor, its basic reason with the interference of frequency converter; The interference of large-scale power supply unit is mainly at low frequency end; And the copper core of communication usefulness also can only be in baseband transmission, and baseband transmission makes power line on mechanism, be difficult to remove to the interference of order wire just in low-frequency transmission.
Summary of the invention
The present invention possesses the power cable of HF communication ability, and technical problem to be solved provides a kind of a kind of power cable that possesses the HF communication ability that can eliminate power cable to the telecommunication cable interference.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: possess the power cable of HF communication ability, comprise power copper core and coaxial cable, power copper core and coaxial cable are encapsulated in the power cable.
The beneficial effect that the present invention compared with prior art has is: the present invention carries out communication through coaxial cable; Do not adopt baseband transmission during communication,, but move the frequency range of communication to high frequency through the mode of carrier wave adjustment just not in low-frequency transmission; So just having solved power line disturbs order wire; Increased reliability, also reduced of the requirement of integrated communicaton cable simultaneously, such as can not adding shielding etc. to power cable.
Description of drawings
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 is that power copper core, 2 is that coaxial cable, 3 is power cable.
Embodiment
As shown in Figure 1, the present invention possesses the power cable of HF communication ability, comprises power copper core 1 and coaxial cable 2, it is characterized in that: four power copper cores 1 and a coaxial cable 2 are encapsulated in the power cable 3.
The present invention carries out communication through coaxial cable 2; Do not adopt baseband transmission during communication,, but move the frequency range of communication to high frequency through the mode of carrier wave adjustment just not in low-frequency transmission; So just having solved power line disturbs order wire; Increased reliability, also reduced of the requirement of integrated communicaton cable simultaneously, such as can not adding shielding etc. to power cable.
Above-mentioned power copper core 1 belongs to prior art with coaxial cable 2.
Combine accompanying drawing that embodiments of the invention have been done detailed description above; But the present invention is not limited to the foregoing description; In the ken that those of ordinary skills possessed; Can also under the prerequisite that does not break away from aim of the present invention, make various variations, for example, the quantity of the power copper core 1 among the present invention can be confirmed its quantity according to the needs of reality.
Claims (1)
1. the power cable that possesses the HF communication ability comprises power copper core (1) and coaxial cable (2), it is characterized in that: power copper core (1) and coaxial cable (2) are encapsulated in the power cable (3).
