Daily maintenance of various types of equipment at small weather stations 1, the ground temperature sensor maintenance The location of the ground temperature sensor must be half on the ground, half in the ground, and the head must be tightly integrated with the soil. Some workers on the ground should clean it up regularly to keep the sensor clean and keep the ground loose. These measures are to The ground temperature value and the manually measured meteorological observation value are close to each other, and the error will not be too large. It is also necessary to pay attention to the fact that the low temperature sensor cleans the soil on the surface temperature sensor surface after the rain is over and keeps the surface clean, especially if the soil changes after the strong wind and rain. , Regularly check whether there is water accumulation in the deep sensor casing. Use a piece of bamboo to tie the cotton on the head and place the cotton on the bottom of the casing to make the cotton absorb dry water. When there is regular water, the casing must be re-installed, and regularly check the exposed areas. Whether the cable is damaged, if damaged, replace the cable in time 2, the temperature and humidity sensor maintenance The head of the temperature and humidity sensor has a protective filter cover to prevent the sensing element from being contaminated by dust. If abnormal temperature and humidity are found, the filter cover should be disassembled and the surface dust should be cleaned with a soft brush. The protective filter should be replaced every six months. Cover, regularly check the connection box inside the shutter box for looseness, tighten the fastening screw to ensure good contact 3, pressure sensor Generally, check whether the air hole of the pressure sensor static pressure pipe communicates with the outside is unblocked. If it is not smooth, the air hole should be cleaned to keep it open. Check whether the desiccant in the air pressure sensor turns to pink, if it is, take out and dry 4, the wind sensor maintenance When we found that the sensor's wind is not strong, the wind vane is not very flexible rotation, we must promptly clean the dust on the above, the bearing must be visually checked once a year, check to remove the vane and the wind cup, under normal circumstances, the shaft should be flexible Lubrication, no obvious noise, often observe the wind rod pull rope is loose, if there is looseness should be tightened in time, and calibrate the verticality, if the error of a certain aspect is not easy to find, we can only use artificial observation data to compare, make those Faults are easier to find and compare. When we find that the error is greater than 30 seconds, we should adjust it in time. If we do not adjust it in time, we will increase the errors in the collection and make the problem more complicated.
