Abstract
The utility model relates to a plant photosynthetic active radiation sensor which comprises a light detector, a bracket, a cosine correction sheet, a transmission line and an outer casing. The cosine correction sheet is located above the light detector and is electrically connected with the light detector. The light detector and the cosine correction sheet are in the outer casing. The bracket is located at the lower part. According to the utility model, the provided novel cosine correction improves the accuracy of the sensor; the transparent outer casing is used, so that the light detector and the cosine correction sheet are protected from external interference and the detection effect of the sensor is not influenced; and the bracket is arranged, which is convenient for sensor mounting.
Description
Technical field
The utility model relates to the proportion of crop planting field, is specifically related to the effective radiation sensor of a kind of plant photosynthesis.
Background technology
At present, at agricultural and forestry plant studying technological domain, when observation of plant is grown and recorded, be all manual observation,
Measure and stamp label and make upper record.Be difficult to accomplish accurately, continuously, in real time from the time, the observed data provided be all generally with " day " office, as research and analysis often the cycle very long, the support of the many sets of data of needs just can be accomplished accurate judgement.Plant growth can be obtained in the growth conditions data acquisition aspect various illumination, temperature, humidity and different crossbreeding by the plant growth data sampling sensor, first hand plant growth data can be obtained in real time.But current, for the sensor ubiquity of measuring the solar radiation visible radiation that resolution is low, error is large, poor stability, the harsher shortcoming of application conditions.
The utility model content
For solving existing measurement photosynthesis of plant to the above-mentioned shortcoming of the measurement mechanism of the assimilation effect of light, the utility model provides a kind of novel plant photosynthesis effective radiation sensor.
The utility model is achieved through the following technical solutions:
The effective radiation sensor of a kind of plant photosynthesis comprises: photo-detector, support, cosine trim tab, transmission line, shell, and the cosine trim tab is positioned at the photo-detector top and is electrically connected to, and in the enclosure, support is positioned at bottom for photo-detector and cosine trim tab.
Described shell is light transmitting shell, and light can radiation pass through shell.
Described sensor is connected with external controller by transmission line.
Described support is the adjustable sensor lifting, and sensor can be used in the plnat monitoring of differing heights, and can stretch at an easy rate the inner use of plant tree crown.
The beneficial effects of the utility model are: the novel cosine correction provided by the utility model has improved the precision of sensor; adopt light transmitting shell both to protect photo-detector and cosine trim tab not to be subject to external interference; do not affect again the detection effect of sensor; the installation of sensor is convenient in the setting of support, has enlarged the usable range of sensor.
The accompanying drawing explanation
Fig. 1 is the effective radiation sensor of plant photosynthesis.
Embodiment
The effective radiation sensor of a kind of plant photosynthesis, comprise: photo-detector 3, support 4, cosine trim tab 2,, transmission line 5, shell 1, cosine trim tab 2 is positioned at photo-detector 3 tops and electrical connection, photo-detector 3 and cosine trim tab 2 are in shell 1, and support 4 is positioned at bottom.Cosine trim tab 2 is used for reducing the error of the cosine response of photosynthetically active radiation sensor, improves accuracy and the sensitivity of device.
Described shell 4 is light transmitting shell, and light can radiation pass through shell 4.
Described sensor is connected with external controller by transmission line 5, the light signal collected is transformed into to electric signal transmission and is analyzed to controller.
Described support 4 is the adjustable sensor lifting, adopts the aluminum material, not only firm but also can anticorrosion.
Use if the user thinks for a long time this instrument to be fixed on field, can combine and use by sensor and ring support.
