Visual monitoring system and method for harmful gas in animal house based on terahertz spectroscopy

Abstract

The invention provides a visual monitoring system and method for harmful gas in an animal house based on a terahertz spectroscopy. The harmful gas visual monitoring system comprises a terahertz spectroscopy detection device and a harmful gas detection tank which are fixedly arranged, an air sampling device which is arranged in the target animal house, computer equipment which is in communication connection with the terahertz spectroscopy detection device, and visual alarming equipment which is in communication connection with the computer equipment, wherein the air sampling device is communicated with the harmful gas detection tank; the terahertz spectroscopy detection device is used for carrying out terahertz spectroscopy detection on each harmful gas in the air in the harmful gas detection tank, sending a detection result into the computer equipment and controlling the visual alarming equipment to carry out alarming according to types of the harmful gas with exceeding content. According to the visual monitoring system and method, provided by the invention, detection, advanced early warning and visual alarming of the harmful gas can be accurately realized in real time, and the timeliness and the safety of detection are improved, so that influences, caused by the harmful gas, on livestock are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of terahertz spectroscopy, in particular to a system and method for visually monitoring harmful gases in livestock houses based on terahertz spectroscopy. Background technique [0002] Livestock houses are designed and built for various breeding animals for their wintering, calving, supplementary feeding and growth and development. They can get rid of the constraints of poor living environment conditions and poor ability to resist natural disasters, so as to obtain safe, efficient and high-quality modern animals. The breeding production mode has the characteristics of technical equipment, scientific process, intensive mode and modern management. Livestock houses have become an important type of breeding in my country. Harmful gas in livestock houses is one of the most prominent disasters in modern aquaculture. The feces and urine produced by modern large-scale breeding sites far exceed the self-purification...

Problems solved by technology

Among all harmful gases, ammonia has the greatest impact on the environment. The release of ammonia not only pollutes the environment, but also reduces the efficiency of poultry manure as fertilizer.

[0003] The existing prevention methods are based on the experience of the barn practitioners and small sensors to bring the air collection in the barn to the indoor laboratory for identification, and then take corresponding countermeasures, which cannot meet the needs of accurate, timely, fast and effective prevention , fast, effective and timely scientific detection and early warning methods become the need

[0004] At present, farms generally do not carry out harmful gas detection, but directly ventilate to solve the hazard of harmful gas pollution, resulting in air pollution; in some farms equipped with harmful gas detection instruments, electrochemical workstations are currently the main detection method, but High cost, short service life, and requires professional technicians to operate

Other relatively mature detection methods are still lacking
