    The objective of the discrete measuring device by multivariate nir reflectance of the glucococcal index in grapes for winemaking is to detect and measure the glycocid index in grape for winemaking. From this index the device will identify the stages of maturity of the grape. This will be done automatically using reflectance measurements at certain near-infrared wavelengths. After the calibration of the device, the measurement is made in a timely manner on the surface of the fruit, which is placed inside the system. This system is applicable to quality control in the food industry, in agriculture and in related areas dedicated to research and development.

    The two methods described above are laborious and / or destructive. It would be interesting to be able to replace them with new non-destructive techniques, provided they are approximately as accurate as the physical-chemical methods. In recent times, hyperspectral image analysis techniques have emerged with great potential to become a fast and non-destructive way of performing food analysis. In a work done previously in this laboratory [3], with the help of a near infrared hyperspectral image analysis device (NIR), the sugar concentration and total acidity in grapes vinification, that is, the glucoacidic index.
    Hyperspectral image analysis is therefore a good tool to achieve this purpose, however, the hyperspectral devices present in the market are very expensive. One way to reduce the costs of this type of technique may be to determine which wavelengths are most influential, and to design a spectral measurement device based only on those wavelengths.
    Based on a study conducted previously in this laboratory [3] it has been possible to obtain a reduced number of wavelengths useful for calculating the glucoacidic index. In this way, the 6 most characteristic wavelengths belonging to the near infrared region between 950 and 1650 nm have been selected by statistical treatments, thus minimizing the loss of spectral information.
    The automatic NIR system for determining the glucoacidic index for grape wine vinification presented here would be an option to determine this index non-destructively and faster than the methods traditionally used. And also, with a system much cheaper and more accessible than the hyperspectral devices that are being proposed for these purposes in recent times.

    The discrete NIR reflectance measuring device of the grape glucoacid index in winemaking is based on a sensor that is used to detect the information of light in the NIR that comes from the object of interest. In addition, it has six different lighting components each emitting at different wavelengths. These lighting components, arranged in the form of a circular crown around the sensor, are directed towards the object of interest to illuminate it at an angle of 45 ° and, by reflection, deliver the light to the sensor. The signal is subsequently processed by a microcontroller that determines the glucoacidic index and from it, the stage of maturity in which the grape is found. This information is subsequently transferred to the user through a screen
    Led. DESCRIPTION OF THE FIGURES

    The discrete NIR reflectance measuring device of the grape glucoacid index for winemaking is based on an InGaAS 1 sensor whose detection range is between 800 nm and 1700 nm. The sensor is used to detect the light information in the NIR that comes from the object of interest.
    The discrete NIR reflectance measurement device of the grape glucoacid index for winemaking consists of six different lighting components emitting at 1050 nm, 1150 nm, 1200 nm, 1300 nm, 1450 nm, 1600 nm respectively 2-7. These are directed towards the object of interest to illuminate it at an angle of 45 ° 22 to reduce the specular reflection component that reaches the sensor. By reflection 23, the light reaches the sensor 1; where, the information of the light signal is extracted and the energy reflected by the object of interest is quantified. Once the signal is in the sensor, it converts it to an analog signal. This is conditioned by a signal conditioning stage 9 and subsequently processed by a microcontroller 8.
    The microcontroller 8 contains the algorithms and all the instructions necessary for the operation of the system which are: control the lighting components, receive the conditioned signal, process the received signals, display data, calibration processes and identification process. Within the signal processing, the microcontroller is responsible for translating the spectral data to glucoacidic index values and with this determines the stage of maturity in which the grape is found. The output values of the glucoacid index provided by the microcontroller range from O to 5, considering value 3 as the threshold from which the fruit is ripe. For this, the algorithm includes several mathematical models previously developed for this purpose [3].
    , Sugar concentration
    Glucoacid Index = --------
    Total acidity
    The system is provided with a housing 14 for protection thereof, and also with a support 15 to place the objects of interest and carry out the calibration process.
    or identification The LCD 16 displays: the data of the sensor 1 signal, the indications for calibrating the system and the identification of the glucoacid index. Once the system is calibrated, it automatically goes into mode: waiting for an object of interest; when an object is placed on the support 15, it proceeds to acquire the information of its discrete spectrum and, subsequently, indicates on the screen the maturity phase to which it corresponds or, failing that, displays the legend "out of range" if The information does not fit with the calibration information. If the system is not calibrated, using the LCD screen you will be asked to perform the procedure to calibrate the system. This LCD screen is interconnected with the microcontroller as shown in 17. Communication between the user and the device is possible thanks to three 18-20 buttons.
    The system is energized by means of a 24 V regulated source 24 connected to the current through an external connection. The regulated source converts the 110 V or 220 V AC signal to a 5 V regulated DC signal.
    The support 15 has the function of allowing the object of interest to be placed in such a way that it is in the correct position to receive the illumination from the lighting components 2-7 and subsequently, allow its reflection towards the sensor 1 with the information of the discrete spectrum 23.
    The calibration process is a process that is selected by the user manually. If this sequence is not chosen, the system is initialized with the preprogrammed values. This calibration process begins by requesting a reference target; subsequently, a sequence of illumination and signal capture is executed to normalize the sensitivity levels. Once this task is completed, display a legend informing that the calibration process has been carried out successfully.
    The analysis process occurs when the user selects the option to start sampling. At this time the device proceeds directly to use the pre-programmed values or those of the calibration process. After choosing this sequence, the system will be ready to initiate analysis of the fruit from its reflectance to detect the glucoacidic index and identification of the stage of maturity.
