Wind anemometers also need regular maintenance.
1, wind direction anemometer sensor regular inspection and maintenance
(1) wind direction and wind speed sensor to observe the wind cup and wind vane rotation is flexible and smooth. When abnormalities are found, clean the sensor bearings according to the "User Technical Manual" method, under normal circumstances, the sensor bearings should be cleaned once a year.
(2) humidity sensor maintenance temperature and humidity sensor head has a protective cover to prevent the sensing element is contaminated by dust, the monthly application of soft bristle brush to sweep the dust cover, do not touch the temperature and humidity sensor shroud with your hands or unclean objects, if you find that the contamination is serious, it should be promptly swept with a soft brush, can not be used in a timely manner should be replaced.
(3) air pressure sensor maintenance check the air pressure sensor vent nozzle, there shall be no foreign objects and pollution; monthly buffer box molecular sieve should be removed, dry and then placed in the box, and sealed.
(4) the maintenance of the volume sensor rain barrel water inlet funnel hole is easy to be dust, leaves, grass and leaves blocked, easy to cause rainfall error or lack of measurement. Therefore, it should be checked once a month to remove dust, gravel, grass, etc., and if necessary, the funnel hole can be unblocked with a fine wire to ensure that the rainwater enters the hopper smoothly.
Wind direction anemometer check the barrel, to ensure that the installation is solid, the mouth of the device level.
(5) temperature sensor maintenance a monthly or after the rain should be timely on the ground temperature sensors and shallow ground temperature sensors of the bare ground loosening, levelling. b, monthly should be a comprehensive view of the ground temperature sensors of the shallow ground temperature sensors of the buried situation, to maintain the ground temperature sensors half buried in the soil, half of the ground, sassafras stained floating in the above rain and debris, shallow ground temperature mounting bracket zero marking line should be flush with the ground. c, monthly or after the rain, the ground temperature sensors should be installed to ensure that the ground temperature sensors are installed to ensure that the ground temperature is not too high. C, monthly or after rain and snow melt should check the deep ground temperature hard rubber casing whether there is water, such as water, the head should be tied with cotton or sponge bamboo stick inserted into the pipe to suck the water dry, such as the casing is often found to be waterlogged, it should be examined for reasons, maintenance.
2 Maintenance of the external adapter box every day to check the sealing of the external adapter box.3 Maintenance of the data collector 1) Regularly use a brush to clean up the dust of the collector, do not electrically open the collector chassis as well as connecting and plugging cables, do not electrically undoing or installing sensors.2) Every day to check the collector with the computer, the external adapter (transmitter) connection is not loose, whether it is correct, and found to be loose or incorrect timely corrections.3) Found loose or incorrect timely corrections. ) found that the collector data abnormalities should be timely reset on the collector, if the reset can not be resolved, the collector memory should be cleared. If the memory is cleared from the new start microcomputer still can not solve the problem, should be promptly reported.
4 power supply system maintenance 1) continue to use the power supply system will be discharged once a month, when the battery voltage is lower than 11v, the power supply system automatically sound and light alarm, at this time should be immediately shut down, and timely charging, otherwise the power supply system will be scrapped. 2) continue to use the UPS should be discharged once a month, when the right side of the UPS power markers down to 20% (only two lights are on), the UPS continuous alarm, then should immediately stop discharging, and timely filling of electricity. Stop discharging, and fully charged in time, otherwise the UPS will be scrapped.
5 Computer Maintenance1) Pay attention to the order of power on the order of power on: power supply system - - UPS power supply ----- data collector ----- computer shutdown order: computer ---- collector -------UPS power supply ----- power supply system2) After 72 hours of continuous work, the computer must be shut down once and restarted, in order to eliminate the system's electronic debris.3) Try not to turn off the computer when it reads and writes data.4) 50 to the whole point of time can not be time-aligned, can not modify the time, to avoid losing the whole point of data.6) Rainfall can not be time-aligned, can not modify the time, to avoid losing the cumulative amount of rainfall of the data.7) To smoke in the measurement and reporting duty room, the use of humidifiers, otherwise it will reduce the life of the microcomputer.
6 wind direction anemometer lightning facilities maintenance 1) every year before the rainy season with a ground resistance meter on the observation field, the measurement room ground resistance test, if greater than 4 ohms, then the reason should be identified, if due to corrosion of the ground network is serious, should be redone ground network. 2) every year before the rainy season, should be the power supply surge arrester, the signal surge arrester should be a check, such as found in the aging of the denaturation of the should be replaced in a timely manner. 3) quarterly should be observed at the observation field, the duty room of all instruments grounding wire for a time. The grounding wire of all instruments should be inspected once a quarter, and should be connected in time if it is found to be disconnected or falsely connected. 4) The new instruments and equipments in the observation field and duty room should be grounded on the metal casing, and the grounding wires should be merged into the unified ground network, so that the whole ground network is connected to the electrical appliances, and the ground network is merged into the ground network, and if it is connected by welding, the grounding wires of all the instruments should be taken off in the observation field and the duty room before welding, or else it will be damaged, and the grounding wire of all the instruments will be connected to the earth wire of all the instruments and equipments after welding. After welding, ground all instruments and equipment.
