The photoelectric conversion interface for connecting the clip-on ammeter and the computer consists of a computer interface (1) and an ammeter interface (2) and is characterized in that a wireless transmitting adapter (12) consists of a light-emitting diode (121) and a photoelectric converter (122), and a wireless receiving adapter (21) consists of a photosensitive diode (211) and the photoelectric converter (122). The photoelectric conversion interface has long communication distance, high communication speed, strong interference immunity and simple structure and is convenient to use.
Description
Technical field
The utility model relates to the utility model and relates to the apparatus field that the electromagnetic radiation of infrared radiation, light or shorter wavelength is converted to electric energy, is specially a kind of opto-electronic conversion interface that clamp on amperemeter is connected with computer that is used for.
Background technology
Extensive use along with computer, a lot of equipment have all attached and have been used for the interface that is connected with computer, RS-232 interface is to use very general one at present, even if visual plant also adopts in a large number, but RS-232 is a point-to-point interface, and this transmission range that has limited between equipment and the computer can not surpass 15m.Simultaneously, USB interface is also used on computers in a large number at present, a common desktop computer has 2～4 USB interface, but when a computer connects a plurality of USB external equipment simultaneously, if these external equipments have been got involved high voltage interference, just may burn out the USB interface of computer, when serious even will damage computer and external equipment.In the practice, clamp on amperemeter often needs be connected with computer, and clamp on amperemeter during owing to the factor of its environment for use regular meeting bring high voltage interference into, this just makes that the influence to computer was even more serious when clamp on amperemeter was connected with computer.
The utility model content
In order to overcome the defective of prior art, a kind of communication distance length, the conversion equipment of strong interference immunity are provided, the utility model discloses a kind of opto-electronic conversion interface that clamp on amperemeter is connected with computer that is used for.
The utility model reaches goal of the invention by following technical solution:
A kind ofly be used for the opto-electronic conversion interface that clamp on amperemeter is connected with computer, form by computer interface and ammeter interface, computer interface is made up of the USB plug and the wireless transmitting adaptor that connect by lead, the ammeter interface is made up of the wireless receiving adapter and the RS-485 plug that connect by lead, it is characterized in that: wireless transmitting adaptor is made up of light-emitting diode and optical-electrical converter, USB plug, optical-electrical converter is connected by lead successively with light-emitting diode, the wireless receiving adapter is made up of photodiode and optical-electrical converter, photodiode, optical-electrical converter is connected by lead successively with the RS-485 plug.
Describedly be used for the opto-electronic conversion interface that clamp on amperemeter is connected with computer, it is characterized in that: optical-electrical converter adopts the fast infrared line standard.
