Description
Technical field
The present invention relates to the dedicated power supply units in power supply unit, especially weather station.
Background technique
Modern Automatic Meteorological Observatory System has been roughly divided into generally according to the timeliness and manual intervention degree for providing data
People's type on duty and unattended type two major classes.
Wherein, Attended mode type is typically mounted on the area of commercial power supply abundance, such as airdrome synoptic station, weather station.
The sensing apparatus such as the sensor at Attended mode type automatic Observation station and data processing terminal are usual at a distance of tens meters to several kilometers,
Between can be by the way of wired data communication, real-time property is preferable.
Unattended type automatic weather station is commonly used in setting up the area at someone station, including desert, plateau, seashore in inconvenience
Etc. the severe area of climatic environments, complete climatological observation and weather resource investigation.These areas can not usually ensure stable city
Power supply needs unmanned weather station that can support a variety of power supply modes such as solar energy, wind energy, while being equipped with the electric power storage of certain capacity
Pond is as backup power supply, and with support system 3~7 days even for longer periods continuous work, therefore Automatic Meteorological Observatory System is set
Timing usually requires to consider to reduce power consumption.
It is connect currently, domestic and international most of Attended mode type automatic weather stations mainly rely on the distribution box in observation field directly to draw
Alternating current in A.C. distribution box carries out AC/DC and DC/DC power conversion in outdoor synthetical collection cabinet, be collector and
Each outdoor sensor provides suitable operating voltage.If in there is also commercial power supplies for erecting bed unstable, line voltage wave
Larger problem is moved, needs to be equipped with outdoor UPS uninterruptible power supply+battery also usually to solve the above problems.Specifically, battery
It is typically placed in direct-current power distribution cabinet, can also be placed in individual waterproof sealing structure with UPS uninterruptible power supply.
Unattended type weather station power pack generally includes solar battery, solar charging controller and battery
Deng being that collector, sensor and wireless telecom equipment etc. provide direct-current working volts by solar charging controller.It is some just
It takes in formula and hand-held automatic weather station, mainly by storage battery power supply, for needing long-time field continuously to power, it is also desirable to
It is equipped with solar battery and solar controller.
Automatic weather station is a kind of pair of temperature, humidity, air pressure, wind direction, wind speed, radiation, sunshine, evaporation capacity, visibility etc.
The surface weather observation equipment that multiple meteorological elements are acquired in real time, handled, stored and transmitted, the equipment can reduce observation
Person works' amount, improves observed efficiency and quality.As meteorology influence movable on national economy is increasingly taken seriously, gas
As the real-time and accuracy of observation data are more and more important, the automatic meteorological device controlled by electronic equipment and computer is gradually
The artificial observation of ground substitution hard work just becomes trend.But since meteorological sight detection is a kind of highly professional subject,
More meteorological professional knowledge is needed, automatic Observation equipment development receives certain limitation.Now, Finland VAISALA company
The Meteorological Products of production use in the several countries in the whole world 70 and 20 several areas and the scope of organization.From in July, 1999, China
Automatic weather station, is put into the observation field of meteorological element by the automatic weather station for introducing Finland VAISALA company for the first time.In this
Meanwhile China also establishes the research and development echelon of oneself, the automatic meteorological observation dress for the voluntarily R&D and production higher efficiency of quickening one's step
It sets, on January 1st, 2000, first automatic weather station formal brought into operation.Currently, automatic remote meteorological station China
It is commonly used, successfully realizes the perfect combination of manual meteorological station and automatic weather station.Current country's automatic weather station is raw
It is many to produce manufacturer.But generally speaking, although the existing automatic weather station development speed in China quickly, with regard to its meteorological sensor
There are also a certain distance with World Developed Countries for technical level.Moreover there is also one for the layout of the existing weather station in China
The technique production of fixed deficiency, detection instrument, measuring technique, the depth of basic research and equipment need to be improved.Thus, into one
Step improve China's surface weather observation automatization level, update automatic weather station and improve dosimetric sensors measurement accuracy and
Efficiency becomes the Main way of current meteorological field.
The power supply subsystem of the above automatic weather station has the disadvantages that
1. in existing most automatic weather station, power protection, the power conversion unit of power pack are generally integrated in acquisition
In device, this integrated design can make that the automatic Weather Station collector of early stage is powerful and structure is simple.But prolonged
Using finding in summary, power failure is one of most common failure of automatic Weather Station, and such design necessarily brings system maintenance
Property it is insufficient, be unfavorable for malfunction elimination and problem exclude.
2. whether someone station and unmanned station, power pack are all to carry out special designing according to system requirements at that time,
When system requirements change, adaptive deficiency of the system for changes in demand.Such as is there is alternating current confession in someone weather station
When answering unstable, power supply subsystem needs to consider to increase UPS uninterruptible power supply and battery, it is also necessary to extraly consider equipment
Place space or environmental protection measure.
3. current China's operation automatic weather station has larger deficiency on lightning protection measures.Its power supply and signal lighting protection grade are all
Have to be hoisted.
4. lacking comprehensive power supply status monitoring.Currently, power supply status monitoring is still with electric in collector circuit in system
It is main to monitor collector operating current and voltage data based on stream/voltage monitoring, thus the power ground shape of side light system
State；And lack the condition monitoring to external power supply unit.
5. general automatic weather station is continuous work after power supply, midway is not supported generally to control the operation of power-off.Such as
Fruit power supply can effectively be controlled by program or software, and system can efficiently control reduction system power dissipation, and this function is to no popularity
As station makes great sense.Because the wireless telecom equipment of system is the unmanned most important current consuming apparatus in station, and unmanned station data
Frequency is not high, and most of time system is in standby, and if can accurately control the power supply shutdown of communication equipment, just
It can be to substantially reduce system power dissipation.
