Description
Technical field
The utility model relates to optical networking pick-up unit, particularly a kind of novel hand-held light power meter.
Background technology
. light power meter is the necessary equipment of test optical fiber and optical device test, be widely used in engineering site test and production test, relative to single binary channels power meter equipment, Multichannel optical power meter achieves multiple channel optical power synchronism detection, improve testing efficiency, current Multichannel optical power meter adopts Universal Asynchronous Receive/dispensing device (being called for short " UART ") to realize communicating between master control borad and head end test plate, because UART does not belong to bus, can only realize 1 to 1 communication, therefore master control borad must adopt a lot of UART ports, UART wiring quantity for communicating is many, be limited to the feature of UART simultaneously, the speed of communication is low, in addition, UART communication does not possess frame concept, the application inconvenience when continued high load data communication.
Light power meter is mainly used in the measurement of continuous light signal power; be widely used in the field such as optical cable construction and maintenance, optical fiber communication, Fibre Optical Sensor, Optical CATV, existing light path rate detecting head exposes, and can not obtain good protection; button does not arrange insulation system, dangerous.
Utility model content
The purpose of this utility model provides a kind of novel hand-held light power meter with automatic Proofreading, life-span length to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, a kind of novel hand-held optical power gauge designed by the utility model, comprise the light power meter main body with display screen and button, the back of the body end of this power meter main body is provided with battery compartment, the upper end of light power meter main body is provided with interface, it is characterized in that: described button outer end is provided with can the dust-proof protective layer with waterproof, and described light power meter main body side is also provided with AccessPort interface.
Preferably, described light power meter main body outer end cover has soft protective jacket.
Preferably, described button comprises LIGHT button, ZERO button, DB button and λ button.
Preferably, described interface is general-purpose interface, and general-purpose interface is connected with block, supports SC/FC/ST interface.
Preferably, inner photoelectric conversion module, classification programmable amplifier, A/D modular converter and the processor be also connected with successively of light power meter main body.
A kind of novel hand-held light power meter that the utility model obtains, have shell firm, volume is little, lightweight, is easy to carry and the feature of low-power consumption, adopts LCD display, makes surveying work more convenient.
