Abstract
The invention discloses a gravity induction packing container with an amplification circuit. The gravity induction packing container with the amplification circuit comprises a gravity inductor, the amplification circuit, a single chip microcomputer and a buzzer. The gravity inductor is fixedly arranged at the top end of a shell body of the packing container. When the gravity inductor inducts the rotation of the packing container, the amplification circuit amplifies induction signals and transmits to the single chip microcomputer, and the single chip microcomputer drives the buzzer to work. By means of the arrangement of the gravity inductor on the packing container, when the packing container is selected, the gravity inductor inducts signals of rotation of a container body, the signals are amplified by the amplification circuit and transmitted to the single chip microcomputer, and the single chip microcomputer drives the buzzer to remind people that the packing container rotates. Therefore, damage of articles caused by improper placement of the articles can be avoided. Through adoption of the negative feedback amplification circuit, amplification signals are stable.
Description
Technical field
The present invention relates to the packing chest field, particularly, relate to a kind of gravity sensing packing chest with amplifying circuit.
Background technology
At present, packing chest is used in the industry-by-industry, uses packing chest goods to be packed the transportation that can make things convenient for goods.But many special article are arranged in the process of transportation, need to specifically put, above many packing chests are arranged, mark arrow, point out that placed face down.But in large batch of goods transport, or in the daily operation, inverted situation often occurs, thereby the article injury of opposite.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of gravity sensing packing chest with amplifying circuit, the advantage that the article of avoiding the placement of article mal to cause with realization damage.
For achieving the above object, the technical solution used in the present invention is:
A kind of gravity sensing packing chest with amplifying circuit, comprise gravity sensor, amplifying circuit, micro controller system and buzzer phone, described gravity sensor is installed in the top of packing case, when described gravity sensor is sensed the packing chest rotation, induced signal after amplifying, amplifying circuit is transferred to micro controller system, described Micro Controller Unit (MCU) driving buzzer phone work, 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.
Further, described micro controller system adopts 51 micro controller systems.
Further, described micro controller system adopts the 80C51 chip.
Technical scheme of the present invention, by at packing chest weight sensor being set, when packing chest is selected, weight sensor is sensed the signal of casing rotation, this signal is transferred to micro controller system after amplifying circuit amplifies, the Micro Controller Unit (MCU) driving buzzer phone reminds people to notice that packing chest rotates, thus the article damage of avoiding the placement of article mal to cause.Adopt negative feedback amplifier circuit, make amplifying signal more stable.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
