Description
Technical field
The utility model relates to a kind of unidirectional information carrying means.
Background technology
Existing many moneys are applied to the USB unidirectional transmission equipment of data isolation object in the market, but there is following problem: first, its one-way transmission of most of equipment non-physical is unidirectional, and be only that logic is unidirectional, therefore can there is the reverse transfer of control and status signal; The second, even if the signal that some equipment does not return, but the signal of telecommunication itself can not ensure isolation completely, has reverse electromagnetic coupled to a certain degree; The two problems more than existed all result in the signal of telecommunication can not realize physical isolation completely, therefore in theory still there is the risk of information reverse leakage.
Utility model content
The purpose of this utility model is to provide a kind of unidirectional information carrying means, to overcome currently available technology above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of unidirectional information carrying means, comprise transmitter side control circuit and receiver side control circuit, unidirectional optical coupling isolator is provided with between described transmitter side control circuit and receiver side control circuit, one end of described transmitter side control circuit is provided with several transmitter side interfaces, and one end of described receiver side control circuit is provided with several receiver side interfaces.
Further, described unidirectional optical coupling isolator is the unidirectional optical coupling isolator of high speed.
Further, described transmitter side interface comprises serial ports, USB interface, Ethernet interface, IEEE 1394 interface, high-definition multimedia HDMI.
Further, described receiver side interface comprises serial ports, USB interface, Ethernet interface, IEEE 1394 interface, high-definition multimedia HDMI.
The beneficial effects of the utility model are: apparatus structure is simple, handled easily, the unidirectional isolation of transfer of data is realized by unidirectional optocoupler, cost is lower, and reliability is higher, effectively achieve the physical isolation of information one-way transmission, and improve security performance, be conducive to the propagation and employment in market.
