Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things equipment for animal husbandry, and in particular to a precise temperature measurement and control system. Background Art

[0002] In recent years, with the widespread application of intelligent infrared body temperature screening systems in medical and epidemic prevention, infrared temperature measurement systems have also begun to be applied to livestock health management. However, existing products are either industrial temperature measurement products with temperature measurement accuracy that is not suitable for live animals, or live temperature measurement products with poor thermal imaging resolution, which are not enough to be used for accurate temperature measurement of livestock. The use of high-precision infrared imaging equipment often makes it difficult to achieve real-time synchronization of high-resolution temperature measurement raw data under limited hardware resources and communication conditions (such as livestock and poultry houses, farms, etc.) due to the large single imaging data flow, and it is difficult to achieve effective separation between the acquisition end and the processing end and the calculation end; this increases the difficulty of maintenance on the processing end on the one hand, and increases the workload of R&D personnel in raw data collection and calculation on the other hand (after the temperature measurement is completed, there is still a large amount of data export, temperature evaluation and statistical work waiting to be completed manually, which further brings about the uncertainty of human differences); based on the above, there is an urgent need for an accurate temperature measurement control system that can be applied to limited hardware resources and communication conditions and has the ability to process and synchronize high-resolution data in real time. Summary of the invention

[0003] In response to the above-mentioned problems in the prior art, the purpose of the present invention is to provide a precise temperature measurement and control system, which adopts a high-precision temperature measurement terminal to meet the high-precision temperature measurement needs while reducing the hardware requirements of the acquisition end, and can meet the large-scale precise temperature measurement in scenarios with limited hardware resources and communication conditions; the system also has an analysis terminal for real-time data uploading and data analysis, reducing the workload of manual data processing.
