Description

TECHNICAL FIELD

[0001] The utility model relates to a gamma energy spectrum monitoring device, especially to an environmental gamma energy spectrum monitoring device for open field deployment. BACKGROUND

[0002] In the event of a radiological / nuclear emergency, monitoring with a field-installed gamma energy spectrum monitoring device is very important for real-time identification of atmospheric radionuclides. This in turn helps to quickly implement countermeasures against radionuclides, thereby greatly reducing the overall exposure of radiation workers, the public, facilities and the environment.

[0003] The existing gamma energy spectrum monitoring device mainly has two application scenarios: a scenario where alternating current power supply can be continuously and stably supplied, and an unattended field environment where power supply cannot be continuously supplied. For the scenario where alternating current power supply can be continuously and stably supplied, a gamma spectrometer is generally used, which mainly includes a gamma ray sensor and a computer. The gamma ray sensor is responsible for capturing gamma rays in the environment and converting them into electrical signals for real-time data analysis in the computer. For the open and unattended field environment, a gamma spectrum detection device is used to collect on-site gamma ray energy, radiation dose rate, time spectrum data, radionuclide spectrum, etc. and send them to a remote cloud platform for data processing through wireless transmission. The gamma spectrum detection device uses solar power supply, but the solar panel is fixed in orientation and cannot adjust the orientation and inclination angle with the change of the sun position, so the power generation efficiency is low. Moreover, due to the intermittent nature of solar energy and the inability of the fixed orientation solar panel to flexibly track the sun, the power generation of the product will fluctuate greatly with changes in weather and sunlight conditions, which will affect the stable operation of the radiation monitoring system and the continuity of data collection.

Its structure basically includes a control circuit, a motor and a solar photovoltaic panel. The control circuit includes two photosensitive resistors and a TDA2822 chip. The photosensitive resistors are located on both sides of the solar photovoltaic panel and collect incident light intensity to send to the chip for comparison processing.
