Abstract
The utility model discloses a solar power weighting meter. A meter display part is mounted in a casing, the meter is characterized in that a solar battery is mounted outside the casing, a power supplycontrol module and a storage battery are mounted inside the casing, the solar battery is connected with the power supply control module, the power supply control module is respectively connected withthe meter display part and the storage battery, the storage battery is connected with the meter display part, the power supply control module is equipped with a protective circuit, and the meter is provided with a stabilized voltage power supply interface. The weighting meter adopts the solar battery, can change the luminous energy to the electric energy and directly supplies power for the meter;and the solar battery supplies power for the meter, and charges for the storage battery at the same time, the solar battery can not directly supply power for the meter when the light is insufficient,but the storage battery can be used for supplying power for the meter. By adopting the two methods of the solar battery and the storage battery to alternately supply power for the meter, the servicelife of the storage battery can be prolonged, and when not in use for a long time, all that is needed is to place the meter in the lighting position to self-refresh, therefore, the use is convenient.
Description
Technical field
The utility model relates to a kind of weighing instrument, particularly a kind of sun power weighing instrument.
Background technology
At present, known electronic platform scale instrument is used accumulator or electric power network power supply, needs periodic charge or connect electrical network for a long time to use.Must periodic charge or the special-purpose supply line of laying when occasion is used in the open.But under the situation of some open-air occasion, remote districts, power supply inconvenience, use relatively difficulty.And the instrument of using accumulator needs periodic charge to safeguard that nonstandard maintenance can reduce the life-span of battery.
Summary of the invention
The utility model provides a kind of sun power weighing instrument, and purpose is to solve the prior art problem, provides a kind of charging convenient, can be in the open air or the weighing instrument of long-term use under the situation of electric power supply inconvenience.
The utility model technical scheme that adopts of dealing with problems is:
The sun power weighing instrument, the instrument display unit is installed in the housing, it is characterized in that: housing is equipped with solar cell outward, energy supply control module and accumulator are installed in the housing, solar cell links to each other with energy supply control module, energy supply control module is connected with instrument display unit and accumulator respectively, and accumulator is connected with the instrument display unit.
Also is furnished with holding circuit in the described energy supply control module.
Described instrument has the stabilized voltage supply interface.
The beneficial effects of the utility model: this weighing instrument adopts solar cell, luminous energy can be converted into electric energy under well-lighted situation, is instrument power supply directly, and it can be used for a long time the local of power supply inconvenience.Because solar cell also can be charge in batteries when being instrument power supply, solar cell can not directly be an instrument power supply under the situation of insufficient light, but can use accumulator to be instrument power supply.Owing to adopt solar cell and two kinds of methods of accumulator alternately instrument to be powered, prolonged the serviceable life of accumulator, reduced pollution to environment.The time spent has not been placed on illumination place with instrument and can have charged voluntarily for a long time, need not manual maintenance, and is easy to use.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; the sun power weighing instrument is equipped with instrument display unit 2 in the housing 1, a solar cell 3 is installed outside the housing 1; energy supply control module and accumulator are installed in the housing 1, and wherein energy supply control module includes holding circuit.Solar cell 3 links to each other with energy supply control module, and energy supply control module is connected with instrument display unit and accumulator respectively, and accumulator is connected with instrument display unit 2.Also has stabilized voltage supply interface 4 on the instrument.
The solar cell 3 that has on the instrument can be more than one, and solar cell 3 can be positioned at front, reverse side or the top of housing 1, and solar cell 3 is positioned at the back side of housing 1 in the present embodiment.3 pairs of accumulators of solar cell charge when sufficient irradiate light, and power to weighing instrument.
The solar cell working principle as shown in Figure 5, during use, towards sunlight, solar cell 3 is converted into electric energy with luminous energy and by energy supply control module accumulator is charged with solar cell 3, simultaneously by energy supply control module to instrument power supply.When sunlight illumination is not enough, this moment solar cell 3, the electric energy that is transformed is not enough to instrument is powered, powered to instrument by electric energy stored in the accumulator this moment.Solar cell 3 was also sustainable when instrument was closed charges reserve power for the use of start back to accumulator.
Is furnished with holding circuit in the instrument; when not using for a long time, only need solar cell 3 can be charged to accumulator towards well-lighted place; holding circuit will stop charge in batteries after accumulator is full of electricity, and preventing to overcharge causes damage to accumulator.Prolong the serviceable life of accumulator.
Weighing instrument configuration stabilized voltage supply interface 4 can adopt electrical network that accumulator is charged under the situation of overcast and rainy or long-term insufficient light.
This weighing instrument adopts solar cell, luminous energy can be converted into electric energy under well-lighted situation, is instrument power supply directly, and it can be used for a long time the local of power supply inconvenience.Because solar cell also can be charge in batteries when being instrument power supply, solar cell can not directly be an instrument power supply under the situation of insufficient light, but can use accumulator to be instrument power supply.Owing to adopt solar cell and two kinds of methods of accumulator alternately instrument to be powered, prolonged the serviceable life of accumulator, reduced pollution to environment.The time spent has not been placed on illumination place with instrument and can have charged voluntarily for a long time, need not manual maintenance, and is easy to use.
