Abstract
The invention discloses a kind of packing chest of certainly lowering the temperature with amplifying circuit, the sidewall of packing chest arranges small fan, the inner set temperature sensor of described packing chest, temperature signal is transferred to micro controller system by this temperature sensor after A/D change-over circuit, described micro controller system controls according to temperature signal the small fan be arranged on sidewall and rotates, amplifying circuit of connecting between described A/D change-over circuit and micro controller system.By arranging small fan on casing, and in casing set temperature sensor, when the temperature in casing is higher than design temperature, micro controller system just control small fan running, thus the object that realization is lowered the temperature to the temperature in casing, reach temperature intelligent cooling object in casing.
Description
Technical field
The present invention relates to packing chest field, particularly, relate to a kind of packing chest of certainly lowering the temperature with amplifying circuit.
Background technology
At present, in the transportation needing vegetables, because itself can produce a large amount of heats, need to lower the temperature to it, existing technology all adopts refrigerator-freezer car to carry out low-temperature transport, but low temperature can reduce the moisture in vegetables, thus reduce mouthfeel and the nutrition of vegetables, as adopted the transport trolley with ventilation function, then reasonably can not lower the temperature to the vegetables in each packing chest, rotting of Vegetable can be caused unavoidably.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of packing chest with intelligent cooling function, to realize in the advantage to temperature intelligent cooling in casing.
For achieving the above object, the technical solution used in the present invention is:
A kind of packing chest of certainly lowering the temperature with amplifying circuit, the sidewall of packing chest arranges small fan, the inner set temperature sensor of described packing chest, temperature signal is transferred to micro controller system by this temperature sensor after A/D change-over circuit, described micro controller system controls according to temperature signal the small fan be arranged on sidewall and rotates, amplifying circuit of connecting between described A/D change-over circuit and micro controller system:
Described amplifying circuit: the first resistance that the inverting input of transport and placing device A1 is connected, to connect between described transport and placing device A1 inverting input and transport and placing device A1 mouth the second resistance and the 4th resistance, second resistance and the 3rd resistance of connecting between the 4th resistance intermediate node and ground, the 5th resistance of connecting between the in-phase input end of described transport and placing device A1 and ground.
Technical scheme of the present invention, by arranging small fan on casing, and in casing set temperature sensor, when the temperature in casing is higher than design temperature, micro controller system just controls small fan running, thus the object that realization is lowered the temperature to the temperature in casing, reach temperature intelligent cooling object in casing.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
