Background technology
Along with development of science and technology, the development of communications industry is particularly rapid, multiple communication modes occurred, and these communication modes respectively have pluses and minuses, and commonly used has:
The serial communication mode is in the RS232 communication again; Be meant that computer passes through the mode that the RS232 international standard protocol is carried out communication with serial port connecting wire and single device (controller); Communication speed (baud rate Baud Rate): common have 1200,2400,4800,9600,19200, a 38400bps etc., baud rate is big more, and transmission speed is fast more; But stable transmission range is short more, and antijamming capability is poor more.
The basic communication mechanism of RS485 and RS232 is consistent, and it is short that his advantage is to have remedied the RS232 communication distance, can not carry out the shortcoming that multiple devices carry out network management simultaneously.Computer connects many 485 equipment successively through the RS232RS485 transducer, adopts the mode of poll, and the equipment on the bus is carried out communication in turn.
10/100base tx RJ45 interface is the Ethernet interface of using always, supports 10,000,000 and 100,000,000 adaptive network connection speeds.
Optical Fiber Transmission advantage: 1, bandwidth; 2, loss is low; 3, in light weight; 4, antijamming capability is strong; 5, fidelity is high; 6, reliable working performance.
CAN (CONTROL AREA NETWORK) is a German BOSCH company for solving a kind of serial communication network that the exchanges data between the numerous controllers and transducer is developed on the automobile; Because it has that antijamming capability is strong, reliability is high, real-time is good and is easy to characteristics such as use; Being widely used in a plurality of fields such as industrial automation, the vehicles, Medical Instruments, building automatic, is to be known as one of the most promising field bus technique.
The SC optical fiber interface office of being mainly used in net switched environment provides this interface on dried million switches of some high-performance and router, its shell adopts moulding technology, processes with the mold fiberglass plastic, is the square type; Plug ferrule (also claiming contact pin) is processed by high technology ceramics, and coupler sleeve is a metal slotted grommet structure, and its physical dimension is identical with the FC type, and end face is handled and adopted PC or APC type lapping mode; Fastening means is to adopt insert-pull pin door bolt formula, need not rotate.This type of connector is cheap, plugs easy to operately, and insertion loss fluctuation is little, and compression strength is higher, and packing density is high.
At present at home so that the data protocol translation interface of selling on the world market reach hundreds of; Can carry out data transaction between these interfaces; Comprise RS232 and change RS485 interface, RS232 commentaries on classics RJ45 interface, optical fiber interface commentaries on classics RJ45 interface, RS232 commentaries on classics CAN interface; But neither one data protocol conversion equipment is included all common interfaces forms up to now, relates in particular to photoelectric conversion technique phoenix feathers and unicorn horns especially; Therefore the data transaction intermediate link between all types of interfaces is many, uses inconvenience very.
The utility model content
The utility model technical problem to be solved is: a kind of multi-functional data transducer is provided; Can realize the data transaction between these five big types of common interfaces of RS232 interface, RS485 interface, RJ45 interface, CAN interface and SC optical fiber interface; To cut down the number of intermediate links convenient the use.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the multi-functional data transducer; Comprise housing; Said housing is provided with RS232 interface, RS485 interface, RJ45 interface, CAN interface and SC optical fiber interface; Be provided with in the said housing and be used to receive signal and carry out data compilation again or carry out the protocol conversion process module that photoelectricity changes mutually according to the corresponding interface corresponding protocols mode, described RS232 interface, RS485 interface, RJ45 interface, CAN interface and SC optical fiber interface all are connected with the protocol conversion process module.
As a kind of improvement, said protocol conversion process module comprises that TxD sends data cell, RxD receiving data units, RTS request transmitting unit, CTS clear to send unit, DSR data preparatory unit, DCD carrier wave detecting unit and DTR terminal preparatory unit.
After having adopted technique scheme; The beneficial effect of the utility model is: owing to RS232 interface, RS485 interface, RJ45 interface, CAN interface all are connected with the protocol conversion process module with the SC optical fiber interface; Five big types of common interfaces are concentrated link together, realized whole digital information treatment technologies, merged the advantage of total interface; Remedied simultaneously the deficiency of each interface again each other; The signal decomposition that each protocol interface is received is an initial data, in the built-in data storage of the equipment that is kept at, when each interface uses, adopts the corresponding interface corresponding protocols mode to carry out data compilation again or carry out photoelectricity and change mutually; Reduce intermediate link, made things convenient for the user to use.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing 1 is the structural representation of the utility model embodiment;
Among the figure: 1, protocol conversion process module, 2, the RS232 interface, 3, the RS485 interface, 4, the RJ45 interface, 5, the CAN interface, 6, the SC optical fiber interface.
Embodiment
Shown in accompanying drawing; A kind of multi-functional data transducer; Comprise housing; Said housing is provided with RS232 interface 2, RS485 interface 3, RJ45 interface 4, CAN interface 5 and SC optical fiber interface 6; Be provided with in the said housing and be used to receive signal and carry out data compilation again or carry out the protocol conversion process module 1 that photoelectricity changes mutually according to the corresponding interface corresponding protocols mode; Described RS232 interface 2, RS485 interface 3, RJ45 interface 4, CAN interface 5 all are connected with protocol conversion process module 1 with SC optical fiber interface 6, and said protocol conversion process module 1 comprises that TxD sends data cell, RxD receiving data units, RTS request transmitting unit, CTS clear to send unit, DSR data preparatory unit, DCD carrier wave detecting unit and DTR terminal preparatory unit.
During use,
Send on data cell and the RxD receiving data units at TxD,
Logical one (MARK)=-3V～-15V
Logical zero (SPACE)=+ 3～+ 15V
On RTS request transmitting unit, CTS clear to send unit, DSR data preparatory unit, DCD carrier wave detecting unit and DTR terminal preparatory unit,
Signal effective (connecting ON state, positive voltage)=+ 3V～+ 15V
Invalidating signal (breaking off OFF state, negative voltage)=-3V～-15V
More than regulation has been explained the definition of RS-323C standard to logic level, and for data (information code): the level of logical one (mark) is lower than-3V, and the level of logical zero (spacing) is higher than+3V; For control signal; On-state (ON) is that the effective level of signal is higher than+3V, and off-state (OFF) is that the level of invalidating signal is lower than-3V, just when the absolute value of transmission level during greater than 3V; Circuit can be checked out effectively; Between-3～+ voltage between the 3V is meaningless, be lower than-15V or be higher than+voltage of 15V also thinks meaningless, therefore; During real work, should guarantee that level is between ± (3～15) V.
Through the definition of above logic level the signal that the need translation interface receives is decoded, be compiled as the interface protocol pattern after the conversion via the internal data processor.
The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection range of the utility model.
