Description

A kind of serial ports conversion equipment

Technical field

The utility model is related to field of computer technology, more particularly, to a kind of technology of serial ports conversion.

Background technology

Developing rapidly with information technology, in the control system of many modernization centralized management, needs to use monolithic To realize various tests and control function, single-chip microcomputer is a wide in range address to machine, and it includes many types, much series, its Feature is the attribute that one piece of IC chip has computer, is widely used in every field.The overwhelming majority is single Piece machine all has the peripheral hardware with external device communication so as to very easily information exchange can be carried out, and these equipment are most of to be used Serial Port Line is attached, and Serial Port Line is in equipment communication using very universal.

Serial ports is the abbreviation of serial line interface, and also referred to as serial communication interface (being often referred to com interface), is using serial communication side The expansion interface of formula.Serial line interface presses electrical standard and agreement divides and includes RS-232, RS-422, RS485 etc., wherein, RS- 232 serial ports are a kind of the most frequently used serial communication interfaces, also referred to as standard serial port.Its full name is " data terminal equipment (DTE, Data Terminal Equipment) between data communication equipment (DCE, Data Communicate Equipment) serial two enter Data exchange interface technical standard processed ".

When using serial communication, the information receiving end (RXD) of an equipment will be with the information transmitting terminal (TXD) of another equipment It is connected, information transmitting terminal (TXD) will be connected with the information receiving end (RXD) of another equipment, that is, so-called intersection is even Connect.For serial ports in actual use, the serial ports type of distinct device have needle-like (male), pass (female) point, such as Fig. 1 and It is respectively needle-like RS-232 DB9 and pass RS-232 DB9 schematic diagram shown in Fig. 2.

Usually Serial Port Line used has direct-connected line and two kinds of cross spider, is respectively applied to different demand scenes, not simultaneously Needle-like (male) and two kinds of pass (female), therefore conversion head or data line group is had to have 6 kinds of lists altogether with the serial ports of equipment The Serial Port Line of one species：Male-male direct-connected, male-public transport fork, female-female direct-connected, female-female intersection, male-female direct-connected, male-female intersection.? Carry out distinct device debugging or communication between devices when, certain conversion head in above-mentioned 6 kinds or data wire may be used, this will Depending on field apparatus.

At present, conversion head on the market or data wire are all single, and existing equipment species is various, various kinds of equipment interface Type-Inconsistencies, the serial communication connected mode that each producer adopts is also different, has using direct-connected connection, has using intersection even Connect, the Serial Port Line of existing single kind cannot meet live needs.User needs to be bought according to actual demand, so standby many The Serial Port Line of class single kind, relatively costly.Or, a Serial Port Line can be cut off by user in centre, finds out holding wire, In debugging process, direct-connected or intersect both of which under carry out manual wiring etc., however, so needing to consume a longer time choosing With or transformation Serial Port Line with matching unit, inefficiency.In variety classes equipment debugging, above procedure is loaded down with trivial details, efficiency is low, non- Often not convenient, and need to be known a priori by the interface type of equipment to be debugged.And the Serial Port Line of single kind cannot get simultaneously The receiving data of equipment and transmission data, if whole communication informations of certain equipment will be obtained, need more or more complicated Data wire.

Therefore, how to realize a kind of serial ports conversion equipment, facilitate user in time, effectively to connect using this serial ports conversion equipment Connect all kinds of equipment possessing different interface type, and obtain equipment bi-directional data using this this serial ports conversion equipment, become this One of problem of skilled person's urgent need to resolve.
