Description
Technical field
The present invention relates to field of computer technology, particularly relate to the technology of a kind of serial ports conversion.
Background technology
Along with developing rapidly of information technology, in the control system of many modernization centralized management, need to use monolithic
Machine is to realize various test and to control function, and single-chip microcomputer is a wide in range address, 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
Sheet machine all has the peripheral hardware with external device communication so that it is can carry out information very easily mutual, and these equipment major parts are used
Serial Port Line is attached, and Serial Port Line uses the most universal in equipment communication.
Serial ports is the abbreviation of serial line interface, also referred to as serial communication interface (being often referred to com interface), is to use serial communication side
The expansion interface of formula.Serial line interface is divided by electrical standard and agreement and includes RS-232, RS-422, RS485 etc., wherein, and RS-
232 serial ports are the most frequently used a kind of serial communication interfaces, also referred to as standard serial port.Its full name is " data terminal equipment (DTE, Data
Terminal Equipment) and data communications equipment (DCE, Data Communicate Equipment) between 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
Being connected, information transmitting terminal (TXD) to be connected with the information receiving end (RXD) of another equipment, and the most so-called the intersection connects
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
Needle-like RS-232DB9 and pass RS-232DB9 schematic diagram it is respectively shown in Fig. 2.
Serial Port Line the most used has direct-connected line and reticule two kinds, is respectively applied to different demand scenes, the most not
Having needle-like (male) and pass (female) two kinds with the serial ports of equipment, therefore conversion head or data line group have 6 kinds of lists altogether
The Serial Port Line of one kind: male-male direct-connected, male-public transport fork, female-female direct-connected, female-female intersection, male-female intersection direct-connected, male-female.?
When carrying out debugging or the communication between devices of distinct device, may use certain conversion head in above-mentioned 6 kinds or data wire, this wants
Depending on field apparatus.
At present, conversion head or data wire on the market are all single, and existing equipment is of a great variety, various kinds of equipment interface
Type-Inconsistencies, the serial communication connected mode that each producer uses is the most different, has the direct-connected connection of employing, has employing to intersect even
Connecing, the Serial Port Line of existing single kind cannot meet on-the-spot needs.User needs to buy according to actual demand, the most 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,
During debugging, direct-connected or intersect and carry out manual wiring etc. under both of which, but, so need to consume a longer time choosing
With or transformation Serial Port Line with matching unit, inefficiency.When variety classes equipment debugging, above procedure is loaded down with trivial details, efficiency is low, non-
The most 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 reception data of equipment and transmission data, if to obtain whole communication informations of certain equipment, need more or more complicated
Data wire.
Therefore, how to realize a kind of serial ports conversion equipment, utilize this serial ports conversion equipment to facilitate user in time, effectively connect
Connect all kinds of equipment possessing different interface type, and utilize this this serial ports conversion equipment to obtain equipment bi-directional data, become this
One of skilled person's problem needing solution badly.
