s2, distributing the medicines, wherein the PLC intelligent control unit controls the mechanical arm to convey the corresponding intelligent storage box to the position right above the medicine receiving container so as to distribute the medicines;
s3, weighing the medicine, wherein the high-precision weighing device measures the weight of the medicine falling into the medicine receiving container; according to the measured temperature and humidity data in the intelligent storage box, compensating the weighing result;
s4, packaging the medicines, wherein the medicine packaging unit is provided with a vacuum packaging bag, and the guides to be packaged independently are packaged independently according to the prescription and the administration rule and are bundled and packaged with the subsequent medicine bags;
s5, spraying codes on the medicines, wherein the medicine spraying unit sprays the codes on the vacuum packaging bag according to the patient information, the medication rule and the notice information;
and S6, dispensing the medicine, wherein the medicine dispensing unit is provided with a voice recognition module, recognizes and translates the dialect into standard mandarin, and checks whether the medicine is dispensed.
9. The PLC intelligent dispensing method according to claim 8, wherein in step S6, dialects across the country and data samples of standard Mandarin corresponding thereto are selected, adaptive deep training is performed using an adaptive deep neural network model to obtain a corresponding dialects-Mandarin acoustic conversion model, after training is completed, the dialects-Mandarin acoustic conversion model is evaluated using a test sample set, and after the accuracy probability exceeds a set threshold, the conversion model is issued to identify user voice information of taking a medicine, and the user information is checked to determine whether to dispense the medicine.
10. The PLC intelligent dispensing method according to claim 8, wherein in step S2, a pressure sensor arranged on the clamping structure of the end effector of the mechanical arm reads a pressure value, whether the pressure value of the pressure sensor is within a preset range is judged, if yes, a carrying action is executed, and if not, the clamping force is adjusted; and simultaneously reading pressure values measured by the pressure sensors corresponding to the clamping grooves, and if the difference value of each pressure value is greater than a preset threshold value, adjusting the posture of the mechanical arm until the difference value of each pressure value is less than the preset threshold value.
