The development of modern science and technology has provided a wealth of means and methods for the development of modern agricultural plant protection. The remote real-time monitoring system of pests is a very important monitoring method for pests and diseases. Its successful application has not only improved the workload of traditional monitoring methods. , time-consuming and time-consuming work, and improving the working environment of the monitoring staff has played an increasingly important role in improving the current warning level of pests and diseases, greatly improving the ability of the Chinese agricultural sector to respond to natural disasters, and for large areas of prevention. The control has a certain guiding role and effectively guarantees the safety of food production.

Topp Yunnong R&D and production of remote pest real-time monitoring system applied the most advanced technology, will be remote photo insect report lamp, remote photo spore capture device, wireless remote photo spore capture device, wireless remote automatic weather station, Remote video surveillance systems and other systems are organically integrated and have the function of pest forecasting and disease monitoring. It is one of the specific applications of modern scientific and technological methods in pest and disease early warning monitoring. The system monitors pests remotely and real-time, monitoring data passes. The wireless network is sent to the dispatcher's mobile phone or computer terminal, and the dispatcher can understand the pests and diseases in the field in the control room, and provide timely guidance on large-scale prevention and control based on the knowledge of the occurrence and growth of pests.
With the development of modern plant protection information technology, the general prevention and control of agriculture requires generally unified command and deployment. The remote real-time monitoring system of pests can not only quickly and accurately predict the occurrence of pests and diseases in the monitoring and forecasting area, but also serve as a command and control for experts. The basis for decision-making, and the use of pest remote real-time monitoring systems, can also achieve information sharing, and greatly promote the standardization, networking, modernization, automation, and visualization of agricultural pest forecasting and early warning.
The valve stem is an important part of the valve.
It is used to drive, connect the actuating mechanism or handle, and directly
drive the spool to move or rotate, so as to realize the function of valve switch
or regulation.Valve stem in the valve opening and closing process is not only
moving parts, stress components, but also seals. At the same time, it is
subjected to the impact and corrosion of the medium, and it also causes friction
with the packing. Therefore, in selecting the stem material, it must be
guaranteed that it has sufficient strength at the prescribed temperature, good
impact toughness, scratch resistance, corrosion resistance. The valve stem is a
vulnerable part, and the mechanical performance and heat treatment performance
of the material should be paid attention to when selecting.The valve stem in the
valve opening and closing process, under tension, compression and torsion force,
and direct contact with the media, as well as the relative motion between the
friction and filler, so in the choice of stem material, must ensure that it
provides adequate temperature strength, good impact toughness, abrasion
resistance and corrosion resistance of.
