Embodiment 1

[0014] A device that can continuously measure the intensity of ultraviolet rays in an outdoor environment is characterized in that it includes an ultraviolet emitting device, a radiation detection device, a data monitoring and recording device 8, and a distribution box 3, and the emitting device includes at least one ultraviolet emitting unit. The unit includes an ultraviolet lamp 2 and a lamp bracket 1. The ultraviolet lamp 2 is horizontally suspended on the lamp bracket 1. The ultraviolet lamp 2 in each ultraviolet emitting unit is electrically connected with the distribution box 3, and the control ultraviolet lamp is arranged in the distribution box 3. A timer for switching time and a lamp ballast. The radiation detection device includes at least one ultraviolet radiation probe 5 and a data collector 7. The ultraviolet radiation probe 5 is arranged at the level of the plant canopy below the ultraviolet lamp 2 and connected with the The data collector 7 is connected through t...

Embodiment 2

[0016] The invention provides a device capable of continuously measuring the intensity of ultraviolet rays in an outdoor environment, and its specific implementation method includes the following steps:

[0017] 1. The construction of the device for increasing the intensity of ultraviolet radiation in the outdoor environment. Including the following steps:

[0018] (1) Build a light bracket that is easy to move, disassemble, and height adjustable. Use triangular steel strips with holes, stainless steel strips with holes and screws to make a bracket for hanging the lamp tube. The bracket is light and easy to move and adjust the height of the lamp tube.

[0019] (2) Customized stainless steel rainproof lampshade, install 2 ultraviolet (UV-B) lamp tubes under each lampshade; hang the lampshade on the bracket. Pressing thin steel into a slanted-wall lampshade with a small width can solve the problem that the previous finished lampshade is too large and has an impact on the preci...

Embodiment 3

[0027] To study the effects of enhanced surface ultraviolet radiation on soybean growth. In the experiment, the intensity of ultraviolet radiation was designed as two levels: control (intensity of ultraviolet rays in natural light), treatment (intensity of ultraviolet rays increased). Turn on the power switch, start the ultraviolet radiation generating device, the ultraviolet lamp tube is 1m away from the plant canopy, and realize the increase of ultraviolet radiation. The system composed of ultraviolet radiation probe, data collector and computer as data monitoring and recording device will automatically detect and record the intensity of ultraviolet radiation for control and treatment (test and record every 1 minute in the experimental setting). After the experimental results, the control and treatment UV radiation intensities have been recorded throughout the experiment.

Abstract

The invention relates to a device which can continuously measure ultraviolet radiation intensity in the outdoor environment. The device comprises an ultraviolet transmitting apparatus, a radiant quantity measuring device, a data monitoring-recording device and a distributor case, wherein the transmitting apparatus comprises at least one ultraviolet transmitting unit which comprises an ultraviolet light and a light bracket, and the ultraviolet light is horizontally hung on the bracket; the ultraviolet light in each ultraviolet transmitting unit is electrically connected with the distributor case, and a timer controlling the on-off time of the ultraviolet light and a light tube ballast are arranged in the distributor case; the radiant quantity measuring device comprises at least one ultraviolet radiation detector and a data collecting device, the ultraviolet radiation detector is arranged below the ultraviolet light to be level with a plant canopy and is connected with the data collecting device through a data wire; and radiant strength signals collected by the data collecting device are together transferred to the data monitoring-recording device through a data wire. The invention relatively conveniently builds an adjustable ultraviolet radiation strengthening environment, and can continuously automatically observe and record the ultraviolet radiation strength.

Description

1. Technical field [0001] The invention belongs to the technical and method field of ecological and meteorological environment regulation, in particular to a device capable of continuously measuring the ultraviolet intensity in an outdoor environment. 2. Background technology [0002] Existing technology: The enhancement of surface ultraviolet radiation is a global environmental problem, and it is an important scientific issue to carry out research on the impact of ultraviolet radiation enhancement on ecosystems and its response. However, there are still major deficiencies in the method and technology of artificially simulating the enhancement of ultraviolet radiation. There is a lack of devices that are easy to move, disassemble, and adjust in the field environment, and devices that continuously and automatically measure and record the intensity of ultraviolet radiation. [0003] Due to the large-scale emission of chlorofluorocarbons and other substances by humans, the stra...
