Abstract
The invention discloses a self-cooling packing container with an amplification circuit. A small fan is arranged on a side wall of the packing container. A temperature sensor is arranged inside the packing container and transmits temperature signals to a single chip microcomputer through an analog to digital (A/D) conversion circuit. The single chip microcomputer controls the small fan arranged on the side wall of the packing container to rotate according to the temperature signals. The amplification circuit is connected between the A/D conversion circuit and the single chip microcomputer in series. The small fan is arranged on the packing container, and the temperature sensor is arranged inside the packing container, when the temperature in the packing container is higher than set temperature, the single chip microcomputer controls the small fan to rotate, so that the purpose of cooling of the temperature inside the packing container is achieved, and the purpose of intelligent cooling of the temperature inside the packing container is achieved.
Description
Technical field
The present invention relates to the packing chest field, particularly, relate to a kind of certainly cooling packing chest with amplifying circuit.
Background technology
At present, in needing the transportation of vegetables, because itself can produce a large amount of heats, need to lower the temperature to it, existing technology all adopts the refrigerator-freezer car to carry out low-temperature transport, but low temperature can reduce the moisture in the vegetables, thereby reduce mouthfeel and the nutrition of vegetables, have the transport trolley of ventilation function such as employing, then can not reasonably lower the temperature to the vegetables in each packing chest, can cause unavoidably rotting of Vegetable.
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 be implemented in the advantage to temperature intelligent cooling in the casing.
For achieving the above object, the technical solution used in the present invention is:
A kind of certainly cooling packing chest with amplifying circuit, sidewall at packing chest arranges small fan, the inner set temperature sensor of described packing chest, this temperature sensor is transferred to micro controller system with temperature signal behind the A/D change-over circuit, the described micro controller system small fan that control is arranged on the sidewall according to temperature signal rotates the amplifying circuit of connecting between described A/D change-over circuit and micro controller system:
Described amplifying circuit: series resistance R1 on the inverting input of transport and placing device A1, series resistance R2 and resistance R 4 between described transport and placing device A1 inverting input and the transport and placing device A1 mouth, series resistance R3 between resistance R 2 and resistance R 4 intermediate node and the ground, series resistance R5 between the in-phase input end of described transport and placing device A1 and ground.
Technical scheme of the present invention, by at casing small fan being set, and in casing the set temperature sensor, when the temperature in the casing is higher than design temperature, micro controller system is just controlled the small fan running, thereby the purpose that realization is lowered the temperature to the temperature in the casing has reached temperature intelligent cooling purpose in the casing.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
