The basic information of the target medicine includes the name of the medicine, the shape, size, hardness, water content of the medicine, and the desired pulverization effect, for example, whether the target medicine is desired to be pulverized into a crushed state, a coarse powder state, a fine powder state, an ultra-fine powder state, or a specific size of the medicine pieces is given, for example, a certain medicine is pulverized into medicine pieces having a length of 3mm, the hardness and water content of the medicine are determined, and a basis is set for compaction of the pulverization control parameters to be subsequently performed.
Step S200: putting the target medicine into a crushing unit, setting crushing control parameters based on basic information, and controlling the crushing unit to crush the target medicine based on the set crushing control parameters;
specifically, the medicine to be crushed is put into a crushing unit, crushing control parameters are set by taking basic information of a target medicine as a reference, the crushing control parameters comprise crushing speed and crushing time, the crushing speed refers to feeding speed of the crushing unit, the feeding speed refers to the amount of the medicine put in the unit time, the crushing time is time required for completing a crushing task, and the crushing unit is further controlled by taking the crushing control parameters as the reference to perform medicine crushing treatment.
Step S300: setting an initial airflow control parameter based on the crushing control parameter and the basic information, and controlling an airflow cleaning control unit to filter dust of the crushed target medicine through the initial airflow control parameter;
specifically, after being pulverized, the medicine is divided into three parts, which are respectively: the first part, which is the most desirable part we need, is the large particle drug, collected in the drug reservoir; the second part is a powder medicament which is collected in a powder storage device; and the third part, the unnecessary part, is collected into the dust collecting port. The initial airflow control consists of two parts: the first airflow cleaning control unit controls the medicine storage part, so that only the crushed medicine with the preset particle size in the medicine storage tank cannot have dust, otherwise, the medicine is polluted; and a second airflow cleaning control unit for controlling the dust collecting part to judge whether the dust is too large and not collected in the powder storage device. The air flow control parameter controls the air flow intensity of the air flow cleaning control unit, namely the power of the air flow cleaning control unit during working, an initial air flow control parameter needs to be set according to the crushing control parameter and the medicine basic information, medicine dust which does not conform to the preset particle size in the medicine storage tank is blown out, it is guaranteed that only large-particle medicine which is needed by people is in the medicine storage tank, no dust exists, it is guaranteed that excessive and overlarge dust is not collected in a dust collection part, and medicine loss and waste are caused.
Step S400: setting dust particle size concentration measuring units at the dust collecting port and the medicine storage port, and measuring the dust particle size and the concentration based on the set dust particle size concentration measuring units to generate a particle size measuring result and a concentration measuring result;
specifically, the dust particle size concentration measuring units are respectively arranged at the dust collecting port and the medicine storage port to determine the dust particle size and the dust concentration of the dust collecting port and the medicine storage port, and the dust particle size concentration measuring units are arranged at the medicine storage port to determine whether the medicine particles in the medicine storage port conform to the expected particle size and whether the medicine storage port contains dust, which is one of reference information for subsequently determining the effectiveness of the first airflow cleaning control unit and performing feedback control. The dust particle size concentration measuring unit is arranged at the dust collecting port so as to detect whether large-particle dust is not processed at the dust collecting port and whether the powder medicine is excessively lost or not, because the dust at the dust collecting port is not needed in principle, if the dust concentration is too high or large-particle medicine fragments are generated, the medicine is wasted, and how the effectiveness of the second airflow cleaning control unit is determined according to the particle size measuring result and the concentration measuring result, so that a reference basis is provided for the subsequent feedback control.
Step S500: and generating a feedback air flow control parameter based on the particle size measurement result and the concentration measurement result, and controlling the air flow cleaning control unit to perform pulverization control of the target medicine based on the feedback air flow control parameter.
Specifically, a particle size measurement result and a concentration measurement result of the positions of the dust collection port and the medicine storage port are used as references to generate feedback airflow control parameters, if dust is contained in the position of the medicine storage port, the effectiveness of the first airflow cleaning control unit is too weak, all dust is not blown out, the airflow control parameters need to be adjusted appropriately, and the effectiveness of the first airflow cleaning control unit is increased; if the dust concentration of the dust collection port is too high, the power of the second airflow cleaning control unit is too weak, a large amount of loss of the powdery medicine is caused, the airflow control parameters of the second airflow cleaning control unit need to be adjusted, the power is increased, the powdery medicine is blown out, the powder storage position is collected, on the basis of the airflow control parameters, feedback airflow control parameters are generated, the airflow cleaning control unit is further subjected to feedback control, the crushing control of the target medicine is performed, the medicine is finally obtained, the crushed particles and the powdery medicine are effectively separated from dust, the pollution of the medicine particles is avoided, and the medicine is lost and wasted.

step S530a: and when the measured dust particle size cannot meet the crushing particle size constraint threshold, generating first feedback information, and performing feedback control on the first airflow cleaning control unit based on the first feedback information.
Specifically, the first airflow cleaning control unit controls the position of the medicine storage port, the dust particle size of the medicine storage port is measured through the dust particle size concentration measuring unit, a crushing particle size constraint threshold is set, the particle size can be the diameter of the dust particle, the crushing particle size constraint threshold is the crushing effect which we want to achieve, whether the dust measured particle size meets the crushing particle size constraint threshold is judged, when the dust measured particle size cannot meet the crushing particle size constraint threshold, first feedback information is generated, feedback control of the first airflow cleaning control unit is performed based on the first feedback information, for example, in one medicine crushing process, the dust particle size measurement result of the medicine storage port is 400-600 μm, the crushing particle size constraint threshold which we set is 3-5mm, and therefore the fact that the dust measured particle size cannot meet the crushing particle size constraint threshold is judged to be smaller than the crushing particle size constraint threshold, it is stated that the power of the first airflow cleaning control unit is not large enough, dust exists in the medicine storage port, first feedback information is generated, the working power of the first airflow cleaning control unit is further adjusted to be a standard, the dust which cannot meet the crushing particle size constraint threshold is blown out, and large particles are obtained.
Further, as shown in fig. 3, the airflow cleaning control unit further includes a second airflow cleaning control unit, and the second airflow cleaning control unit is disposed at the position of the dust collecting port, and step S500 in the embodiment of the present application further includes:
step S510b: obtaining the dust measurement concentration of a dust collection port in the particle size measurement result;

step S540b: and performing feedback control of the second airflow cleaning control unit through the second feedback information.
Specifically, the second airflow cleaning control unit controls the position of the dust collection port, the dust concentration of the dust collection port is measured through the dust particle size concentration measuring unit, a dust concentration constraint threshold is set at the same time, the measured dust concentration of the dust collection port cannot exceed the dust concentration constraint threshold, if the measured dust concentration exceeds the dust concentration constraint threshold, the power of the second airflow cleaning control unit is too low, the dust concentration of the dust collection port is too high, a large amount of powder medicine is lost, and medicine waste is caused.

step S620: performing powder characteristic detection on the real-time powder image set to generate a powder characteristic detection result;
step S630: generating third feedback information based on the powder characteristic detection result;
step 640: and performing feedback control of the first airflow cleaning control unit through the third feedback information.
Specifically, the powder storage position is a dust collection position, the collected powder medicine is powder medicine and cannot contain large-particle medicine fragments, the image acquisition unit comprises but is not limited to a camera and a device capable of acquiring real-time images and is in communication connection with an intelligent control system and used for acquiring real-time powder images of the powder storage position, the real-time powder image set comprises a plurality of acquired powder images, the acquired powder image set is subjected to image processing to extract powder characteristics, whether the powder storage position contains large-particle medicine or not is judged, convolution can be selected to check the powder image processing, firstly, image characteristics can be extracted from an image containing the large-particle medicine fragments and serve as standard characteristics, then, the images in the real-time powder image set are subjected to characteristic matching, the matching degree of the characteristics is evaluated according to the numerical value of convolution kernel, whether the large-particle medicine fragments exist in the powder storage position or not is determined, if the large-particle medicine fragments exist in the powder storage position, the first airflow cleaning control unit is over strong, not only dust in the medicine storage tank is blown out, but also large-particle medicine fragments are blown out, third airflow cleaning adjustment information is generated, and the first airflow cleaning control unit is used for ensuring that the airflow control parameters of the first airflow is not blown out.
Further, step S640 in the embodiment of the present application further includes:
step S641: judging whether the first feedback information and the third feedback information exist at the same time;
step S642: when the first feedback information and the third feedback information exist at the same time, performing feedback control on the first airflow cleaning control unit based on the third feedback information, and generating a crushing feeding amount constraint parameter based on the first feedback information;
step S643: and controlling the feeding speed of the crushing unit through crushing feeding amount constraint parameters.
Specifically, the dust particle size at the position of the medicine storage opening is measured by a dust particle size concentration measuring unit, and when the dust particle size measuring result does not meet the crushing particle size constraint threshold, the effect of the first airflow cleaning control unit is over-small, and high power needs to be adjusted, so that first feedback information is generated; the real-time powder images are collected through the image collecting unit arranged at the powder storage position, powder characteristic detection is carried out on the collected powder image set, and the powder storage position is found to contain large-particle medicines, so that the effect of the first airflow cleaning control unit is too strong, power needs to be reduced, and third feedback information is generated based on the effect. We find that the first feedback information and the third feedback information are both feedback-controlled for the first airflow cleaning control unit, and the feedback control of the first airflow cleaning control unit and the feedback control of the third feedback information are different, so we need to judge whether the first feedback information and the third feedback information exist at the same time, and if the first feedback information and the third feedback information exist at the same time, we need to select the third feedback information as a reference for performing the feedback control of the first airflow cleaning control unit, that is, we need to moderately reduce the airflow control parameter of the first airflow cleaning control unit, so as to reduce the power of the first airflow cleaning control unit, and the first feedback information is used for performing the feedback control on the feeding speed of the crushing unit, so as to generate the crushing feeding amount constraint parameter with the first feedback information as a reference, thereby moderately slowing down the feeding speed of the crushing unit, and facilitating the first airflow cleaning control unit to better separate large-particle medicines from dust.
