Detailed Description

The invention is further illustrated with reference to the following figures and examples.

As shown in fig. 1, the fruit sugar data acquisition device of the present invention comprises a fruit juice extracting module, a sugar degree detecting module, a control module 6 and a data storing and transmitting module 7. The fruit juice squeezing module comprises an extruding component 1, a drainage and filtering component 2 and a stirring component 3; the sugar degree detection module comprises a refractometer 4 and an infrared detection component 5, and a sample placing port of the refractometer 4 is arranged right below the drainage and filtration component 2; the control module 6 comprises a single chip microcomputer which is connected with the refractometer 4, the infrared detection component 5 and the data storage and transmission module 7.

The data storage and transmission module comprises a data storage component and a data transmission component. The system also comprises a matched information platform, wherein the information platform comprises a database, a server and executable software facing to an object.

Stirring subassembly 3 comprises paddle and drive structure, and stirring subassembly 3 is installed and is being close to the drainage cup wall, is close to the position of bottom, and when the bottom of cup storage stay to stir the juice, manual control drive structure makes the paddle rotate and accomplishes the stirring process.

The specific embodiment is as follows:

as shown in figures 2 and 3, the fruit to be measured is put on a hard base with holes in the drainage cup, a filter disc with fine holes is attached to the surface of the hard base, and the fruit to be measured is sufficiently squeezed and ground so as to be crushed and the juice can flow out.

The clarified juice filtered by the filter disc will reach the bottom of the cup along the wall of the drainage cup, and the juice will be temporarily stored in the drainage cup due to the switch at the bottom of the cup being in the off state. At this time, the juice is sufficiently stirred by the stirring component 3, so that the components of all parts of the juice are uniform. Then the pull-type switch at the bottom of the drainage cup is opened to drip the juice, and the pull-type switch is closed after the juice drips.

The juice drips the in-process and can pass through infrared detection subassembly 5, and infrared detection subassembly 5 will produce a pulse signal and transmit the singlechip rather than being connected this moment, and the singlechip then can be after the very short delay with this signal conversion control signal to transmit refractometer 4 rather than being connected, and the very short delay is in order to let the juice have abundant time to drip on the sample detection region of refractometer 4. And after receiving the control signal from the single chip microcomputer, the refractometer 4 automatically starts to work, juice positioned on the sample detection area is continuously detected for three times, and the continuous three-time detection result can be displayed on a display screen of the refractometer. If the operator thinks that the measurement has a certain error, the sugar degree of the sample to be measured can be measured again by manually controlling the control module 6 of the refractometer 4.

When the operator considers that the measurement result is reliable, the switch of the control module 6 can be turned on, the single chip microcomputer controls the refractometer to store the measurement result to the data storage component, and after the measurement of the batch is completed, the single chip microcomputer controls the data sending control switch on the refractometer to upload the detection result stored in the data storage component to a designated database.

The database is placed on a server, main data types of the database comprise production place information, brix data and user information, data in the database can be read and written in real time through object-oriented executable software, data variance, median, most value, mean value, mode, variation coefficient and quartile are calculated, and data distribution conditions are expressed through a histogram, a scatter diagram and a box diagram.

Before the next detection, the drainage cup, the stirring component and the refractometer sample placing opening need to be cleaned and replaced by a new filter disc.
