[Abstract]:In this paper, in connection with the project of "Science and Technology Project of High yield of Grain" in the 11th Five-Year Plan of Science and Technology support, a physical method for rodent killing by electromagnetic radiation has been developed, which can be used in the field of rodent and rodent control in grain storage, and a set of methods that can be used in the field of rodent and rodent control is developed. The pseudo-random rodent control system (STD-1), which is used in the medium grain depot without directional rotating electromagnetic field radiation, can gradually solve the problem of postpartum loss of grain. In this paper, we first collected a large number of biomedical experimental data and related literature records, comprehensively analyzed the effects of electromagnetic field frequency range and radiation intensity on the reproductive ability, central nervous system, learning ability of mice, etc. The frequency range and magnetic field intensity of electromagnetic field which are more serious to mice are determined, and the theoretical basis for the development of "STD-1" system is established. The design of pseudorandom undirected rotating electromagnetic field radiation "STD-1" device is divided into three parts: 1: research and design of signal source; 2: research and design of adaptive coding control system; 3: pseudorandom random rotating electromagnetic field radiation. In the research and design of pseudo-random rotating electromagnetic field radiation "STD-1" device, the method of "pseudo-random broad-spectrum compound frequency" signal as artificial field source is put forward for the first time to realize rodent and rodent extermination in grain storage environment. In the research and design of signal source, some key technologies, such as broad-spectrum property, initial phase synchronization, multi-frequency synchronous transmission and so on, are studied and designed. In the research and design of adaptive coding control system, the key technology of unoriented adaptive control of magnetic field is studied and designed. In the research and design of pseudorandom random rotating electromagnetic field radiator, the electromagnetic field theory analysis and the corresponding analysis of magnetic field intensity of low frequency current element radiation are carried out for the radiator part. A grounding dipole radiation device with invention patent is designed and simulated on computer. Through the whole machine test and simulation experiment of "STD-1" simulator, the result shows that the research and design of the system of "STD-1" reach the design requirements.
