Description

The connection device of nonstandard bus connector system and STD bus connector system

Technical field

The present invention relates to data highway system, particularly a kind of system and the interconnect equipment that has used the STD bus connector system that has used the nonstandard bus connector.

Background technology

IEEE 1394 high-speed serial bus (being called for short 1394) standard, the trade mark that originates from Apple is called the high-speed serial bus standard of " Firewire ".In Dec nineteen ninety-five, IEEE 1394-1995 high-speed serial bus standard is adopted by the ieee standard council and ratifies.In order further to improve and improve the serviceability of bus, interconnected improve more and desirable that makes equipment between bus, the ieee standard council replenishes 1394 bus standard agreements, this complementary agreement is granted in March, 2000, be named as IEEE 1394a-2000 high-speed serial bus standard, its related content comprises: improve bandwidth utilization, bus reset, power management etc.Along with the continuous development of technology, its high-speed bus standard IEEE-1394b standard of future generation also went through in 2002, and supported Bus Speed is 800Mbps, 1.6Gbps and 3.2Gbps, and supported the different medium cable, as: plastic optical fiber etc.At present, the product that is operated in 800Mbps now occurs, and the equipment of 1.6Gbps also can appear on the market soon.If realized this speed, hundreds of video channels can transmit in real time by one 1394 bus.The IEEE-1394 standard except transmission speed soon, the transmission of real equity also is one of key advantages of IEEE-1394.

Since IEEE 1394 high-speed serial bus have plug and play, speed height, with low cost, be easy to superperformance such as use, on many equipment, all adopt IEEE 1394 high-speed serial bus products at present, mainly comprised household electrical appliance, PC and built-in External memory equipment, PC peripherals etc.

And along with the increase of the industry spot traffic, existing fieldbus has been difficult to satisfy the requirement in the real work.IEEE 1394 might become the novel bus standard of industry spot.In the aerospace field, also have at present with IEEE 1394 as communication bus dynamically, the observing and controlling environment that these fields all require to realize data transmission has high reliability in all fields.

But for IEEE 1394 high-speed serial bus that solution PC field multimedia communication problem is invented are not considered the request for utilization of connector in rugged surroundings.As the reliability that connects etc.Therefore, the defined various connectors of IEEE 1394 standards are at present the IEEE1394 high speed data bus to be applied in one of major obstacle in the observing and controlling environment that requires the high reliability data transmission.This problem can be easily by defining the nonstandard bus connector solution that other satisfies IEEE 1394 standard connector electrical specifications and can use in rugged surroundings.But this can bring the another one problem simultaneously, the uses such as test environment of a large amount of in the market available IEEE 1394 systems all be the bus connector of standard, how using the equipment as these test environments etc. in the system that has used the nonstandard bus connector effectively, is a problem that presses for solution.

Summary of the invention

The objective of the invention is to overcome the system that has used the nonstandard bus connector and can not be connected to the defective of having used the STD bus connector system, a kind of system and the equipment that has used the system interconnection of STD bus connector that has realized using the nonstandard bus connector is provided.

To achieve these goals, the invention provides the connection device of a kind of nonstandard bus connector system and STD bus connector system, comprise IEEE1394 STD bus connector 2 and non-IEEE1394 STD bus connector 3; It is characterized in that, also comprise the transmission of a deal with data and the physical chip 1 of reception usefulness; Described STD bus connector is meant the connector that satisfies IEEE 1394 high-speed serial bus standards at different levels, and described nonstandard bus connector is D connector or the aviation plug that satisfies IEEE 1394 standards on electrical specification; Described physical chip 1 has plural IEEE1394 mouth, wherein at least one IEEE1394 mouth links to each other with described IEEE1394 STD bus connector 2, and at least one IEEE1394 mouth is used for being connected with described non-IEEE1394 STD bus connector 3.

In the technique scheme, described physical chip 1 is the physical chip that satisfies IEEE 1394 each grade standard, is the various products that comprise TSB41AB3, TSB41LV04A, TSB41LV06, TSB41AB2, TSB41BA3, TSB81BA3.

In the technique scheme, described IEEE1394 STD bus connector 2 has one or more, and described non-IEEE1394 STD bus connector 3 has one or more.

The connection device of nonstandard bus connector system of the present invention and STD bus connector system has realized having used the system of nonstandard bus connector to be connected in the system that uses the STD bus connector, has solved problem how to use STD bus connector equipment in the system that has used the nonstandard bus connector effectively.
