Abstract
The utility model discloses a multifunctional photoelectric integrated converter, which comprises an MCU, a light receiving module, a light emitting module, an RS232 interface, an RS485 interface and a USB interface. The light receiving module, the light emitting module, the RS232 interface, the RS485 interface and the USB interface are respectively connected with the MCU. The MCU is used for receiving signals sent by one of the TTL interface of the MCU itself, the RS232 interface, the RS485 interface, the USB interface and the light receiving module, and converting the signals into signals adapted to the output processing standards of the other four of the TTL interface, the RS232 interface, the RS485 interface, the USB interface and the light receiving module. In this way, due to the adoption of the multifunctional photoelectric integrated converter, the inter-conversion of signals adapted to the processing standards of the RS232 interface, the RS485 interface, the TTL interface and the USB interface, and optical signals can be realized. Meanwhile, the multifunctional photoelectric integrated converter is simple in structure and lower in cost.
Description
Technical field
The utility model relates to a kind of communication interface conversion device, relates in particular to a kind of multifunctional photoelectric one transducer.
Background technology
For short haul connection, interface commonly used mainly contains RS232, RS485, USB etc., and distinct device uses different interfaces, and same equipment generally can not have above-mentioned three kinds of interfaces concurrently, the connection communication issue that this just exists distinct device to cause because of distinct interface.And the control external equipment processor mostly uses is TTL signal or LVTTL signal, therefore, have the signal transfer problem between processor and the peripheral hardware equally.And for long haul communication, for example 2 485 equipment will carry out 5 kilometers communication, use traditional RS232 or RS485 then can't realize, but it can realize that through Optical Fiber Transmission there is the conversion of signal equally in this by converting the electrical signal to light signal.
Though the product of signal conversion in the market is a lot, all has the single deficiency of translation function.Some electric signal transducer can be realized conversion a kind of even two or three clock signal, can realize mutual conversion between RS232, TTL and the usb signal three such as the RS232-TTL-USB transducer, certain application is arranged in short haul connection, but can't be competent at for this series products of long haul communication; Though some types of fiber product can be realized the mutual conversion of the signal of telecommunication and light signal, yet there is the single deficiency of translation function equally.For example the RS485 fibre optic modem can be realized the exchange of 485 signals and light signal, but the kind of this series products switching signal is often very limited, can not satisfy the application of distinct device flexibly, and such valuable product.
The utility model content
The purpose of this utility model is to provide a kind of multifunctional photoelectric one transducer, to realize the mutual conversion between RS232, RS484, TTL, USB and the light signal.
For achieving the above object, the utility model provides a kind of multifunctional photoelectric one transducer, comprise MCU, and the Optical Receivers that links to each other with described MCU respectively, light emission module, the RS232 interface, RS485 interface and USB interface, described MCU is used for receiving self TTL interface, described RS232 interface, described RS485 interface, the signal that one of described USB interface and described Optical Receivers send, and this signal is converted to be suitable for described TTL interface as required, described RS232 interface, described RS485 interface, other four signals that output is handled in described USB interface and the described light emission module.
Multifunctional photoelectric one transducer of the present utility model, described MCU is single-chip microcomputer.
Multifunctional photoelectric one transducer of the present utility model, described Optical Receivers and described light emission module replace with optical transceiver module.
The signal that the MCU of multifunctional photoelectric one transducer of the present utility model can send one of reception self TTL interface, RS232 interface, RS485 interface, USB interface and Optical Receivers, and as required this signal is converted to the signals that are suitable for other four output processing in TTL interface, RS232 interface, RS485 interface, USB interface and the light emission module.Therefore, multifunctional photoelectric one transducer of the present utility model can be realized the mutual conversion between RS232, RS484, TTL, USB and the light signal, and it is simple in structure, and cost is lower.
Description of drawings
Fig. 1 is the schematic block circuit diagram of multifunctional photoelectric one transducer of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
With reference to shown in Figure 1, the multifunctional photoelectric one transducer of present embodiment comprises MCU(, and it adopts processing modules such as single-chip microcomputer), and the Optical Receivers that links to each other with MCU respectively, light emission module, RS232 interface, RS485 interface and USB interface.Wherein, MCU is used for the signal that one of reception self TTL interface, RS232 interface, RS485 interface, USB interface and Optical Receivers send, and as required this signal is converted to the signals that are suitable for other four output processing in TTL interface, RS232 interface, RS485 interface, USB interface and the light emission module.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model; for example Optical Receivers and described light emission module are replaced with optical transceiver module etc., all should fall in the definite protection range of claims of the present utility model.
