The non-attachment power supply and signal transmission device is characterized in that the emission apparatus is composed of an over-voltage protection circuit, an intermediate-frequency pulse generator, a power conversion circuit and a primary coil iron core, which are connected orderly; the receiving apparatus is formed by connection of a secondary coil iron core and a power restoring circuit, and the primary coil iron core and the secondary coil iron core are not interconnected, and are spaced by a certain gap. The non-attachment power supply and signal transmission device has the advantages of simple structure, convenience in use, steady operation, strong environmental suitability, long service life and the like.
Description
Technical field
The invention belongs to contactlessly powered and signal transmission technology field, particularly one is powered and signal transmission device without line.
Background technology
In the prior art, electric power transfer mainly adopts fixed electric wire transmission or has the electric power transfer mode of contact, but in a lot of product, there is the situation mutually needing transmission signal between motion two parts, the parts of parts as relatively-stationary in bottom and top rotary motion need the situation of transmission signal, such as: the product such as illuminator, radar system.The said goods all also exists not only needs supply of electric power, need again relative motion between parts, and currently used settling mode mainly realizes from mistake slip ring structure, the principle of slip ring structure is arranged on a contact on the ring-type of a conduction or the conductor of other present situations, can keep in touch in sliding process, thus reach the effect of electric energy transmitting; But the problem existing for this transmission structure is: first, two objects mutually move and produce friction, and object is damaged very soon, and useful life is limited; Second: easily produce loose contact between the conductor of motion mutually, thus produce spark, produce the damage that big current accelerates object; 3rd: due to motion mutually so be work under the state do not completely not cut off with air in a lot of situation, therefore be easily corroded in adverse circumstances.Therefore, develop a kind of can the new equipment of non contact transmission signal, become contactlessly powered and one of signal transmission technology field urgent problem.
Summary of the invention
The object of the present invention is to provide simple, easy to use, stable the powering and signal transmission device without line of a kind of structure.
The object of the invention is to adopt such technical solution to realize
:it comprises emitter and receiving system; it is characterized in that described emitter is made up of the overvoltage crowbar be connected successively, medium-frequency pulse generator, power converting circuit and primary coil iron core; described receiving system by secondary coil iron core and power supply also primary circuit be formed by connecting; described primary coil iron core is not connected mutually with secondary coil iron core, and has certain gap between the two.
Described overvoltage crowbar is by independently exchanging overvoltage crowbar and DC over-voltage protection circuit forms.
The present invention adopts converter technique and electromagnetic conversion principle, feeder ear Power convert can be become intermediate-freuqncy signal, then the magnetic field of corresponding frequencies is produced through primary coil iron core, secondary coil iron core is positioned at the magnetic field that primary coil iron core produces, secondary coil iron core can convert the magnetic field that primary coil iron core produces to electric energy, and the electric energy that secondary coil iron core converts to becomes to have power power-supply through power supply reduction circuit reduction; The present invention has that contactless transfer of electrical energy, energy loss are low, delivery of electrical energy safety and stability, can any environment be adapted under work, the advantages such as long service life.
