Technical field

The utility model relates to a kind of meteorological observation device, and machine is observed and predicted on specifically a kind of intelligent power supply ground.

Background technology

The automatic weather station ground measuring and reporting system of present national meteorological department is to adopt common computer to observe and predict machine as ground, is equipped with the ups power of common 4 hours long delays; The 5KW gasoline engine generator is arranged as the stand-by power supply power supply for guaranteeing automatic weather station ground measuring and reporting system 24 continuous throughout the twenty-four hour24s, also using.There is following problem in the electric power system that machine is observed and predicted on this ground:

The one, require of automatic weather station station is laid in outskirts of a town portion more, thereby can only to adopt the rural power grids power supply be power devices, and rural power grids power source voltage variation range is excessive, and surge is frequent, and it is frequent and irregular to have a power failure;

The 2nd, under aging circuit and the nonstandard situation of the construction of line, frequent high pressure intrusion accident makes the device damage situation of ground measuring and reporting system serious;

The 3rd, induction lightening ripple intrusion accident is frequent, and the lightning wave of introducing from supply line accounts for more than 70% of thunderbolt incident;

The 4th, because the rural power grids power supply quality is lower, the change in voltage scope is big, harmonic interference is serious, cause the battery charging and discharging of ups power frequent, battery capacity reduces greatly, serviceable life is well below product design, generally speaking, the automatic weather station ups power used after 1 year, and the power failure of most of ups power time-delay power-on time just shortens to be had only about 1 hour, caused a large amount of replacings of accumulator;

Five are to use the power supply of 5KW gasoline engine generator can't satisfy the requirement of long-term use, if stream time surpasses 10 hours, then its reliability is difficult to guarantee.

Therefore, because the strict demand of ground observation environment has determined that general layout is laid in the outskirts of a town of automatic weather station; And the outwardness of rural power grids power supply unreliability causes device damage serious, and accumulator property reduces, and maintenance cost increases, and data lack the survey problem and also are on the rise.

The utility model content

The purpose of this utility model just provides a kind of intelligent power supply ground and observes and predicts machine, to solve system's powerup issues such as line voltage and quality shakiness, ups power loss be serious, realizes safety, the stable operation of automatic weather station ground measuring and reporting system.

The utility model is achieved in that a kind of intelligent power supply ground observes and predicts machine, the intelligent power supply system and the low-power consumption industrial master board computing machine that are connected to form by intelligent power, solar panel and accumulator join, for low-power consumption industrial master board computing machine provides uninterrupted power source.

Intelligent power described in the utility model is connected and composed by PWM Switching Power Supply, solar charging controller and power management single-chip microcomputer, power module of voltage regulation; The input end of solar charging controller connects solar panel, and the output terminal of solar charging controller connects accumulator by power module of voltage regulation; The external low-power consumption industrial master board of the output of power module of voltage regulation computing machine.

The utility model is main, the auxiliary uninterrupted power source power supply mode to charge in batteries of civil power by selecting for use low-power consumption industrial master board computing machine as the basis that device constitutes, constituting a kind of solar cell for supplying power.In this scheme, adopt solar cell for supplying power, can reduce the turn-on time of civil power, thunder and lightning interference that reduction civil power cable is introduced and surge impact etc. cause the risk of damage to the equipment of ground measuring and reporting system; The civil power of wide region input PWM technology can effectively prevent the damage that the intrusion of 380V ac high voltage causes equipment.

Intelligent power provided by the utility model can be monitored various states information in real time, automatically the control civil power inserts and disconnects, reduce the intrusion risk of high pressure and lightning wave, improved the device security of automatic weather station ground measuring and reporting system thus, reduced scarce survey rate, also reduced the maintenance cost of equipment simultaneously because of the weather information due to the device damage.
