Abstract

The invention relates to an air velocity transducer for monitoring environment, and in particular to an air velocity transducer which is capable of being configured to be current output or voltage output. The velocity transducer comprises a power circuit, a photovoltaic conversion circuit, a single-chip microcomputer minimum system and a digital-to-analogue conversion circuit, wherein the power circuit is connected to the photovoltaic conversion circuit, the single-chip microcomputer minimum system and the digital-to-analogue conversion circuit respectively, the photovoltaic conversion circuit is connected to the single-chip microcomputer minimum system, and the microcomputer minimum system is connected to the digital-to-analogue conversion circuit. Compared with the prior art, the air velocity transducer has the advantages that one air velocity transducer is compatible with four output modes which are 0 - 20mA current output, 4 - 20mA current output, 0 - 5V voltage output and 0 - 10V voltage output. And the required output mode can be configured to be one of the four above modes through modifying embedded software without replacing the air velocity transducer.

Description

technical field [0001] The invention relates to a wind speed sensor for environment monitoring, in particular to a wind speed sensor which can be configured as a current / voltage output. Background technique [0002] Wind speed measurement requires different output methods in different applications. The existing output methods include frequency output, serial bus output, current output and voltage output. Among them, the common current output forms are 0-20mA current output and 4-20mA current output, and the common voltage output forms are 0-5V voltage output and 0-10V voltage output. [0003] The existing wind speed sensor can only provide one output mode in one instrument, if another output mode needs to be used, the sensor needs to be replaced, which increases the cost and brings trouble. Contents of the invention [0004] In view of the problems existing in the existing wind speed sensor, the present invention proposes a wind speed sensor that can be configured as a cu...
