Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.

In the description of the present disclosure, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present disclosure, "a plurality" means two or more unless otherwise specified.

In the embodiment of the application, the visual medicine distribution method is applied to the electronic device, and the electronic device can be a medicine distribution robot per se, and can also be other devices in communication connection with the medicine distribution robot, such as a server or a cloud server (namely a cloud end). As shown in fig. 1, the visual dispensing method includes the following steps.

Step 101: a target quantity of the drug is obtained.

Step 102: the medicine in the medicine storage cup of the medicine distribution robot is pushed to the medicine distribution tray of the medicine distribution robot.

Step 103: the number of the dialed medicines is identified based on the image photographed by the photographing module.

Step 104: and judging whether the number of the dialed medicines is less than or equal to the target number.

Specifically, if it is determined that the number of medicines to be dialed is equal to or less than the target number, step 105 is performed. If it is determined that the amount of the medicine to be dispensed is greater than the target amount, step 107 is performed.

Step 105: the medicine poking rod of the medicine dispensing robot is controlled to poke the poked medicine to the medicine taking cup.

Step 106: it is determined whether the number of medicines dialed is equal to the target number.

Specifically, if it is determined that the number of the medicines to be dialed is equal to the target number, the medicine dispensing process is ended, and if it is determined that the number of the medicines to be dialed is not equal to the target number, the step 101 is executed again. When returning to step 101, the target number obtained in step 101 = the sum of the number of medicines that the user needs to take-the number of medicines each time drawn into the medicine taking cup; alternatively, the target number of drugs = target number in the previous dispensing process-number of drugs drawn to the dispensing cup in the previous dispensing process.

Step 107: based on the image shot by the shooting module, the medicine poking rod is controlled to scratch the medicine from the medicine distribution tray to the medicine fetching cup.

In this application embodiment, through the shooting module of dividing medicine robot, acquire the image of dividing the medicine tray to know the medicine distribution condition of dividing medicine tray top based on the image. The control module controls the medicine poking rod to poke the specified number of medicines to the medicine taking cup according to the medicine distribution condition so that a user can take the medicines conveniently. Compared with the method that a user takes the medicine with a hand after pouring out the medicine, the medicine with the designated quantity is obtained through the medicine distributing robot, and the possibility of manual operation errors is avoided by providing medicine distributing service for the user who does not have the capacity of accurately taking out the medicine with a certain quantity due to diseases. In addition, the medicine dispensing robot is used for obtaining the medicines with the specified quantity, so that the pollution to the medicine not taken at this time is less, and the safety of the medicines is improved.

In one embodiment, for step 101, at the time of first dispensing, the dispensing robot may determine the number of medicines that the user needs to take based on the user's medication plan, and take the required number of medicines as the target number of medicines; alternatively, the dispensing robot sets the number of medicines to be taken, which is input by the user, as the target number of medicines. After the medicine is distributed for the first time, the medicine distribution robot calculates the target number according to the number of the medicines which need to be taken by the user and the number of the medicines which fall to the medicine taking cup each time.

The following exemplifies a manner in which the dispensing robot acquires a medicine taking plan.

The administration plan includes what drugs are taken, the usage amount of the drugs, the administration time, and the like. The medicine taking plan can be input into the medicine dispensing robot by a user, or can be actively sent to the medicine dispensing robot or a cloud end connected with the medicine dispensing robot by a medical service or health service provider of the user at the cloud end, or a request can be sent to the medical service or health service provider of the user by the medicine dispensing robot or the cloud end, and the medical service or health service provider of the user sends the request to the medicine dispensing robot or the cloud end after receiving the request.

In one example, the manner in which the user enters the medication plan into the dispensing robot includes, but is not limited to:

mode 1: the user puts the identification code on the medicine bottle (can be in any place of the medicine bottle) in the shooting area of the external camera of the medicine dispensing robot. The external camera of the medicine dispensing robot scans the identification code attached to the medicine bottle (which can be anywhere on the medicine bottle) to obtain the medicine taking plan. The external camera is a camera located outside the medicine dispensing robot in a shooting area. The identification code may be a two-dimensional code, a bar code, or the like.

Mode 2: the user places the paper material for recording the medicine taking plan in a shooting area of an external camera of the medicine dispensing robot. The dispensing robot recognizes the administration plan on the paper material using an OCR (Optical Character Recognition) technique.

Mode 3: the user interacts with the medicine dispensing robot through a language or a keyboard, and the medicine taking plan is input into the medicine dispensing robot.

Mode 4: the user inputs the medicine taking plan into the terminal, the terminal transmits the medicine taking plan to the medicine distributing robot, or the terminal transmits the medicine taking plan to the cloud, and the cloud issues the medicine taking plan to the medicine distributing robot.

In one embodiment, for step 102, the user or the caregiver of the user separately and independently fills each of the medication (or healthcare products) to be taken into the drug cup of the dispensing robot.

The manner in which the dispensing robot moves the medicine to the dispensing tray is exemplified below.

In one example, a dispensing robot includes: a main shaft; the medicine distribution tray is connected with the main shaft and is provided with a longitudinal through hole; the medicine poking rod is arranged above the medicine distribution tray and connected with the main shaft; the first power module is connected with the medicine poking rod; and a control module connected to the first power module; the shooting module is connected with the control module; the shooting area of the shooting module comprises an area where the medicine distribution tray is located; the medicine taking cup is arranged below the medicine distribution tray; the rotary tray is connected with the main shaft, the rotary tray is arranged below the medicine distribution tray, and the medicine taking cup is arranged on the rotary tray; the medicine storage cup comprises a medicine storage cup wall and a medicine storage cup movable cup bottom, and the medicine storage cup movable cup bottom is positioned in the medicine storage cup wall; the second power module is connected with the rotating tray and is used for controlling the rotating tray to rotate; the first push rod is connected with the movable cup bottom of the medicine storage cup; and the third power module is connected with the first push rod. The medicine dispensing robot controls the medicine dispensing rod to rotate, and medicines are dispensed from the medicines taken out of the medicine storage cup to the medicine dispensing tray.

In another example, a dispensing robot includes: a main shaft; the medicine distribution tray is connected with the main shaft and is provided with a longitudinal through hole; the medicine poking rod is arranged above the medicine distribution tray and connected with the main shaft; the first power module is connected with the medicine poking rod; and a control module connected to the first power module; the shooting module is connected with the control module; the shooting area of the shooting module comprises an area where the medicine distribution tray is located; the medicine taking cup is arranged below the medicine distribution tray; and, a housing; and the hanging rod and the medicine storage cup, one end of the hanging rod is fixed on the shell, and the other end of the hanging rod is connected with the inclined rod at the bottom of the medicine storage cup. When medicine needs to be taken, the control module of the medicine distribution robot controls the inclination angle of the inclined rod to pour the medicine onto the medicine distribution tray.

It should be noted that, as will be understood by those skilled in the art, in practical applications, the medicine in the medicine storage cup may be obtained in other manners, which are not listed in this embodiment.

In one embodiment, before identifying the amount of the medicine dialed based on the image captured by the capturing module, the method further comprises: judging whether the dialed medicine is arranged in a preset shape or not; if yes, a step of identifying the number of the dialed medicines based on the images shot by the shooting module is executed.

It should be noted that, as can be understood by those skilled in the art, the preset form may be a linear form, or may be other forms, and the embodiment is not limited thereto.

It is worth mentioning that the dialed medicines are arranged into a preset shape, so that the electronic equipment can conveniently identify the quantity of the medicines.

It should be noted that, because of the reasons such as the friction between the medicines, the friction of medicine and branch medicine tray and the shape of medicine, when dialling the medicine pole and changeing to the rotation stop bit, the medicine also can't arrange into and predetermine the form, nevertheless no matter whether the medicine arranges into and predetermines the form, through dialling the stirring of medicine pole, the arrangement that the medicine can be ordered relatively has greatly reduced the degree of difficulty that visual system discerned medicine quantity. For arrangement modes with different forms, the artificial intelligence algorithm can accumulate the experience of finding the optimal entry point through continuous learning and is realized through the matching of the front driving lever and the rear driving lever.

In one embodiment, if it is determined that the dispensed drug is not arranged in the predetermined configuration, the visual dispensing method further comprises: judging whether the medicine poking rod reaches a rotation stop position, if so, controlling the medicine poking rod to stop rotating, and identifying the number of the poked medicines based on the image shot by the shooting module; if the determination is not yes, the medicine poking rod is controlled to rotate along the first direction. In order to avoid the falling of the medicine, the medicine distributing robot is marked with a rotation stop position in the medicine distributing working area. And if the medicine poking rod reaches the rotation stop position, the rotation is stopped.

It should be noted that, as can be understood by those skilled in the art, the medicine dispensing robot may learn the rotation stop position of the medicine dispensing working area by learning the image of the medicine dispensing working area with the mark, or may learn the rotation stop position of the medicine dispensing working area by recognizing the mark made on the medicine dispensing working area, which is not listed in this embodiment.

In one embodiment, before controlling the drug-poking rod to rotate in the first direction, the method further comprises: and determining the medicine pulling speed of the medicine pulling rod according to the type of the medicine. Specifically, considering that the shape, weight, external material and friction of each medicine are different, the medicine poking rod can poke the medicine at different medicine poking speeds according to different medicines, so that the medicines are arranged in a preset shape.

In one embodiment, after controlling the medicine poking rod to scratch the medicine from the medicine distribution tray to the medicine fetching cup based on the image shot by the shooting module, the method further comprises the following steps: the medicine poking rod is controlled to poke the residual medicines to the medicine storage cup or the waste medicine cup of the medicine distribution robot.

In one embodiment, after controlling the drug-poking rod to poke the residual drug to the drug storage cup or the waste drug cup of the drug dispensing robot, the method further comprises the following steps: identifying the number of the drawn medicines based on the image shot by the shooting module; judging whether the number of the drawn medicines is equal to the target number or not; if yes, controlling the medicine poking rod to poke the scratched medicine to the medicine fetching cup; if not, judging whether the number of the drawn medicines is smaller than the target number; if the number of the scratched medicines is determined to be smaller than the target number, controlling the medicine poking rod to poke the scratched medicines to the medicine fetching cup, and returning to the step of acquiring the target number of the medicines; and if the number of the drawn medicines is larger than the target number, returning to execute the step of drawing the medicines to the medicine taking cup from the medicine distribution tray based on the image shot by the shooting module and controlling the medicine drawing rod.

In one embodiment, the method for moving the medicine in the medicine storage cup of the medicine dispensing robot to the medicine dispensing tray of the medicine dispensing robot comprises the following steps: determining that the medicine storage cup is positioned below the longitudinal through hole of the medicine distribution tray; a first push rod of the medicine dispensing robot is controlled to push the movable cup bottom of the medicine storage cup to move upwards; the medicine poking rod is controlled to rotate along the first direction so as to poke the medicine in the medicine storage cup.

In one embodiment, the first push rod for controlling the medicine dispensing robot pushes the movable cup bottom of the medicine storage cup to move upwards, and the method comprises the following steps: determining a first moving distance according to the number of the targets; and controlling the first push rod to push the movable cup bottom to move upwards for a first movement distance. Specifically, when the lifting height of the movable cup bottom of the medicine storage cup is too low, the medicine pulled out by the medicine pulling rod is too small, and the quantity of the needed medicine is not enough; the movable cup bottom of the medicine storage cup is too high in lifting height, so that too many medicines are pulled out by the medicine pulling rod, and the difficulty of pulling out the medicines of a target quantity by the medicine pulling rod is increased. Therefore, the medicine distributing efficiency is affected by the fact that the movable cup bottom of the medicine storage cup rises too high or too low. In order to improve the medicine distribution efficiency, the control module controls the rising height of the movable cup bottom of the medicine storage cup to control the amount of the medicines to be dispensed according to the obtained target quantity, and excessive or insufficient medicines are prevented from being dispensed.

Optionally, after determining whether the number of the medicines to be dialed is less than or equal to the target number, the method further includes: adjusting parameters in the first constraint relation or the second constraint relation according to the judgment result; or calculating the difference between the number of the medicines to be dialed and the target number; and adjusting parameters in the first constraint relation or the second constraint relation according to the calculated difference.

The following exemplifies a manner of determining the first movement distance based on the number of targets.

In a first example, the dispensing robot calculates the first movement distance based on the number of targets and a first constraint relationship between the number of targets and the first movement distance. Optionally, the medicine dispensing robot continuously adjusts the first constraint relation based on the first constraint relation initially set by the developer and a subsequent medicine dispensing process, so as to improve accuracy of the first constraint relation.

For example, after determining whether the number of the dispensed drugs is equal to or less than the target number, the dispensing robot adjusts the parameters in the first constraint relationship according to the determination result. Specifically, the determination result indicates a magnitude relationship between the number of medicines dialed and the target number. If the number of the medicines to be dialed is larger than the target number, adjusting parameters in the first constraint relation so that the first moving distance calculated based on the adjusted first constraint relation is smaller than the first moving distance calculated based on the first constraint relation before adjustment for the same target number. If the number of medicines dialed is equal to the target number, the first constraint relationship is not adjusted. If the number of the medicines to be dialed is smaller than the target and the number, adjusting parameters in the first constraint relation, so that the first moving distance calculated based on the adjusted first constraint relation is larger than the first moving distance calculated based on the first constraint relation before adjustment aiming at the same target number.

For another example, after determining whether the number of the medicines to be dispensed is less than or equal to the target number, the medicine dispensing robot calculates a difference between the number of the medicines to be dispensed and the target number, and adjusts a parameter in the first constraint relation according to the calculated difference. If the difference is greater than 0, for the same target number, the first movement distance calculated based on the adjusted first constraint relation is smaller than the first movement distance calculated based on the first constraint relation before adjustment. If the difference is equal to 0, the first constraint relationship is not adjusted. If the difference is smaller than 0, adjusting parameters in the first constraint relationship so that the first moving distance calculated based on the adjusted first constraint relationship is larger than the first moving distance calculated based on the first constraint relationship before adjustment for the same target number.

It should be noted that, as can be understood by those skilled in the art, the first constraint relationship may be a fixed constraint relationship preset by a developer, and the embodiment is not limited.

In a second example, the dispensing robot determines the first movement distance based on the target quantity, the information of the medicine, and a second constraint relationship between the target quantity, the information of the medicine, and the first movement distance. Specifically, the information of the medicine includes information such as a volume of the medicine. Due to the fact that different medicines are different in size and the like, for different medicines, when the same target quantity is to be obtained, the heights of the medicines which need to be higher than the dispensing tray are different, namely the first moving distances are different. Therefore, the medicine dispensing robot can store the first moving distance in advance, and the medicine dispensing robot calculates the first moving distance according to the target number, the medicine information and the second constraint relation.

For example, the medicine dispensing robot adjusts the parameter in the second constraint relationship according to the determination result after determining whether the number of the medicines to be dispensed is equal to or less than the target number. Specifically, the determination result indicates a magnitude relationship between the number of medicines dialed and the target number. If the number of the medicines to be dialed is larger than the target number, adjusting parameters in the second constraint relationship so that the first moving distance calculated based on the adjusted second constraint relationship is smaller than the first moving distance calculated based on the second constraint relationship before adjustment for the same target number. If the number of the medicines dialed is equal to the target number, the second constraint relationship is not adjusted. If the number of the medicines to be dialed is smaller than the target and the number, adjusting parameters in the second constraint relationship so that the first moving distance calculated based on the adjusted second constraint relationship is larger than the first moving distance calculated based on the second constraint relationship before adjustment for the same target number.

For another example, after determining whether the number of the dispensed drugs is less than or equal to the target number, the drug dispensing robot calculates a difference between the number of the dispensed drugs and the target number, and adjusts the parameter in the second constraint relationship according to the calculated difference. If the difference is greater than 0, for the same target number, the first movement distance calculated based on the adjusted second constraint relation is smaller than the first movement distance calculated based on the second constraint relation before adjustment. If the difference is equal to 0, the second constraint relationship is not adjusted. If the difference is smaller than 0, adjusting parameters in the second constraint relationship so that the first moving distance calculated based on the adjusted second constraint relationship is larger than the first moving distance calculated based on the second constraint relationship before adjustment for the same target number.

It should be noted that, as can be understood by those skilled in the art, the second constraint relationship may be a fixed constraint relationship preset by a developer, and the embodiment is not limited.

It should be noted that, as can be understood by those skilled in the art, the dispensing robot may also calculate the first moving distance based on other manners, which are not described herein again.

In one embodiment, before controlling the medicine dispensing robot to dispense the medicine to the medicine taking cup, the method further comprises: and determining that the medicine taking cup of the medicine distribution robot is positioned below the longitudinal through hole.

In one embodiment, controlling the medicine poking rod to scratch the medicine from the medicine distribution tray to the medicine fetching cup based on the image shot by the shooting module comprises: determining a first angle and a second angle based on the image shot by the shooting module; controlling the medicine poking rod to rotate by a first angle along a second direction; the front shifting rod of the medicine shifting rod is controlled to rotate a second angle along the first direction; controlling the medicine poking rod to rotate along a first direction to scratch and fetch medicines to the medicine fetching cup; wherein the first direction and the second direction are opposite in direction. If the first direction is clockwise, the second direction is anticlockwise; if the first direction is counterclockwise, the second direction is clockwise.

Specifically, if the number of medicines dialed by the medicine dialing rod is larger than the target number, the front dialing rod and the rear dialing rod are matched to dispense medicines. Under the guidance of a visual system, the main joint drives the front driving lever and the rear driving lever to rotate for a first angle along a second direction, and then the auxiliary joint drives the front driving lever to rotate for a second angle along the first direction, so that the front driving lever and the rear driving lever form a certain angle. Finally, the auxiliary joint is fixed and the main joint rotates positively to complete the medicine preparation.

In one embodiment, determining the first angle and the second angle based on the image captured by the capturing module includes: determining medicine dialing information according to the image shot by the shooting module; the medicine dialing information comprises any one or any combination of a distribution area of the medicines, a volume of the medicines, the number of the medicines and a target number; determining a first angle according to the medicine dialing information and a third constraint relation between the medicine dialing information and the first angle; and determining the second angle according to the medicine dialing information and the fourth constraint relation between the medicine dialing information and the second angle. For example, a third constraint relation between the medicine dialing information and the first angle is established in advance, and the medicine dispensing robot calculates the first angle based on the third constraint relation and the medicine information. Calculate first angle based on dialling medicine information for first angle is more applicable to the present medicine of segmentation, improves branch medicine efficiency.

It should be noted that, as can be understood by those skilled in the art, the first angle may also be a preset angle, and the embodiment is not limited thereto.

It should be noted that, in the process of dispensing, the vision system may command the main joint and the auxiliary joint to perform fine adjustment according to the condition of the medicine on the dispensing work area, so as to find a better cutting angle.

In one embodiment, the visual dispensing method further comprises: and sending reminding information, wherein the reminding information is used for reminding the user to take medicine.

In one embodiment, the visual dispensing method further comprises: and judging whether the medicine taking cup is in a condition state or not, and if so, recording the medicine taking record of this time so as to record and count the medicine taking condition of the user. The medication record may include the time at which the medication was taken, the type of medication taken, and the number of medications taken.

In one embodiment, the medicine taking record of this time is uploaded to the cloud, so that the cloud records and counts the medicine taking condition of the user.

The medicine is confined in the dispensing work area 122 by the annular gate 121. The dispensing area 122 can be divided into two areas, namely, an area a and an area B. Zone a is the area where the longitudinal through hole 120 is located, i.e. the drug outlet. The region B is a region other than the region a in the dispensing work area 122. Because the inner edge of the medicine distribution working area 122 is smooth and has no dead angle which can not be touched by the medicine poking rod 13, the situation that the medicine distributed at this time is remained in the medicine distribution working area 122 and is wrongly identified as the medicine distributed to the patient at the next time, so that the patient eats the medicine by mistake can be avoided.

Optionally, the transverse through hole is located in the rear deflector rod.

It should be noted that, those skilled in the art can understand that the annular barrier can also adopt other arrangement modes, for example, an annular slide rail is arranged on the medicine dispensing tray, and the annular barrier is connected with the annular slide rail so that the annular barrier can rotate along the annular slide rail; the annular breast board is provided with an opening, and the medicine poking rod is arranged in the opening. Wherein, the opening size with dial the medicine pole phase-match to avoid the medicine to pass this opening and reach annular breast board inside.

In one embodiment, the dispensing robot further comprises: and the reminding module is connected with the control module and is used for reminding to take medicine. In particular, the development of the medical health industry has enabled many diseases to be treated or controlled, greatly improving the health level of human beings and extending the life of human beings. Many diseases that were originally difficult to cure have become chronic diseases that require long-term treatment. The problem that the medicine can not be taken on time is obvious in the long-term taking process. Meanwhile, the kinds of medicines and health care products to be taken by human beings are more and more, and therefore, the problem that the medicines required to be taken cannot be taken correctly and completely is caused. The medication compliance refers to the behavior of the patient in accordance with the medication and the medical orders. The reports of the world health organization show that 50% of the people in the world do not comply, causing huge losses. For example, the efficacy is not expected, and the course of the disease is prolonged; the doctor judges the curative effect wrongly and increases the dosage or changes the medicine; the risk of toxic and side effects is increased; the patient pays a large additional expenditure; wasting valuable medical resources of society, etc. Each individual in the united states is not dependent on an additional medical expenditure resulting in $ 2100 per year. An additional cost of $ 3000 billion per year is incurred in cardiovascular disease. Death of 12.5 million people is caused each year because of non-compliance. Worldwide drug enterprises generate 6000 billion dollars of losses each year because of non-compliance. The reasons for the problem of taking medicine are various, and 70% of the reasons are related to the behavioral factors of the people taking the medicine. These behavioral factors also vary widely from person to person. For example, age is different, most of the reasons for old people are forgetting, most of the reasons for middle-aged and young people are busy, most of the reasons for children are careless careers or immature children, and the like. Therefore, the more extensive administration management includes a series of services such as medicine taking reminding, usage amount prompting, rational medicine taking, patient education, follow-up visits, consultation guidance and the like so as to achieve the purposes of improving compliance and improving curative effect, and is the very important last mile in treatment. In view of these problems, in this embodiment, the medicine dispensing robot can automatically dispense each medicine to be taken, remind the user of taking medicine, know whether the user takes medicine, and even access the therapy. The medicine dispensing robot is placed beside a medicine taking person, and like a home care worker, the compliance of the medicine taking person is improved, and the medicine taking risk is prevented.

It should be noted that the reminding module can also remind the user through other manners. For example, the reminding module is a communication module, the communication module establishes communication connection with a terminal of a user, and reminding is performed by pushing information, sending short messages, making calls, videos and the like to the terminal of the user. For another example, the communication module is in communication connection with a third party (such as a medical care service provider), and the third party reminds the user so that the third party can follow up the medicine taking situation of the user. The embodiment is merely an example, and the implementation manner of the reminding module is not limited.

In one example, the dispensing robot performs the dispensing operation first and then performs the reminder operation. The medicine dividing operation is finished firstly, the user is reminded to take the medicine, and the user does not need to wait for the medicine dividing robot to finish the medicine dividing operation.

In another example, the dispensing robot performs the reminding operation first, and performs the dispensing operation after determining that the user is going to take the medicine through a camera or an infrared sensor. The medicine is re-distributed after the user is determined to take the medicine, so that the situation that the medicine is not taken by people after the medicine is distributed can be reduced.

In one embodiment, as shown in fig. 13, the first power module 31, the second power module 32, the third power module 33, the fourth power module 34, and the fifth power module 35 are all disposed on the main shaft.

It should be noted that all the modules referred to in the foregoing embodiments are logic modules, and in practical applications, a logic unit may be one physical unit, may also be a part of one physical unit, and may also be implemented by a combination of multiple physical units. In addition, in order to highlight the innovative part of the present invention, the above-mentioned embodiments do not introduce elements that are not so closely related to solve the technical problems proposed by the present invention, but this does not indicate that there are no other elements in the above-mentioned embodiments.

The application also provides a visual medicine distribution method based on the visual system of the medicine distribution robot. The vision system includes a shooting module and a vision algorithm (such as an image recognition algorithm), wherein the vision algorithm may be set in the control module, or may be set in a cloud, a terminal, or an edge server. The following description will be given taking the example of the visual dispensing method performed by the dispensing robot as an example. As shown in fig. 14, the visual dispensing method performed by the dispensing robot includes the following steps.

Step 201: a target quantity of the drug is obtained.

Step 202: the medicine in the medicine storage cup of the medicine distribution robot is pushed to the medicine distribution tray of the medicine distribution robot.

Step 203: the number of medicines dialed out is identified based on the image taken by the camera module.

Step 204: and judging whether the number of the dialed medicines is less than or equal to the target number.

Specifically, if it is determined that the number of medicines to be dialed is equal to or less than the target number, step 205 is executed, otherwise, step 207 is executed.

Step 205: the medicine poking rod of the medicine distribution robot is controlled to poke the poked medicine to a first preset position. The first preset position is the position of the longitudinal through hole.

Step 206: it is determined whether the number of medicines dialed is equal to the target number.

Specifically, if it is determined that the number of the medicines to be dispensed is equal to the target number, the medicine dispensing process is ended, and if it is determined that the number of the medicines to be dispensed is not equal to the target number, the process returns to step 201. That is, if the number of the medicines dialed by the medicine dialing rod is exactly equal to the target number, the medicine distributing robot controls the medicine dialing rod to continue rotating until all the medicines are pushed into the medicine taking cup. If the number of the separated medicines is smaller than the target number, the medicine distributing robot controls the medicine poking rod to continue rotating until the medicines are pushed into the medicine taking cup. The medicine dispensing robot continues the next medicine dispensing process. In the next medicine dispensing process, when the medicine dispensing robot acquires the target quantity of the medicines, acquiring the target quantity of the medicines = the quantity of the medicines which need to be taken by the user-the sum of the quantity of the medicines which are divided into medicine taking cups each time; alternatively, the target number of drugs = target number in the previous dispensing process-number of drugs dispensed to the dispensing cup in the previous dispensing process.

Step 207: based on the image of shooting the module shooting, the preceding driving lever and the back driving lever of control group medicine pole remove, draw from dividing medicine tray and get the medicine. Step 205 is then performed.

Through the operation, the medicine dispensing robot can dispense the medicines of the quantity required to be taken by a user to the medicine taking cup by controlling the medicine dispensing rod so as to realize automatic medicine dispensing.

In one embodiment, as shown in fig. 15, a visual dispensing method performed by a dispensing robot includes the following steps. Step 301, step 307, step 308, step 309 to step 311 are substantially the same as step 201, step 203, step 204, step 206 and step 207 respectively shown in fig. 14, and the same parts are not repeated herein, and differences are mainly introduced below.

Step 301: a target quantity of the drug is obtained.

Step 302: the rotary tray of the medicine distribution robot is controlled to rotate to a second preset position, and a first push rod of the medicine distribution robot is controlled to push the movable cup bottom of the medicine storage cup to move upwards.

Specifically, when the rotary tray is located at the second preset position, the medicine storage cup of the medicine distribution robot is located below the longitudinal through hole.

Optionally, before the first push rod is controlled to push the movable cup bottom of the medicine storage cup to move upwards, the medicine dispensing robot determines that the rotary tray is located at the rotary position, the rotary tray is controlled to rotate to a second preset position, and when the rotary tray rotates to the second preset position, the medicine storage cup is located below the longitudinal through hole, as shown in fig. 16 a. When the rotary tray is located the second preset position, the medicine storage cup for storing the required medicines is located below the longitudinal through hole. The dispensing robot controls the rotary tray to ascend to the dispensing position as shown in fig. 16 b. The medicine dispensing robot controls the first push rod to push the movable cup bottom of the medicine storage cup to move upwards, so that the medicines in the medicine storage cup pass through the longitudinal through hole and reach the upper part of the medicine dispensing tray, as shown in fig. 16 c.

Optionally, divide medicine machine robot control first push rod to promote the medicine storage cup activity bottom of cup rebound, include: determining a first moving distance according to the number of the targets; and controlling the first push rod to push the movable cup bottom to move upwards for a first movement distance.

Step 303: the medicine poking rod is controlled to rotate along the first direction.

Specifically, as shown in fig. 17a to 17d, the medicine dispensing robot drives the rear shifting lever, the auxiliary joint and the rear shifting lever to rotate by controlling the main joint, so as to dispense a certain amount of medicines from the medicine storage cup to the B area of the medicine dispensing working area.

Optionally, the start point of the drug-dialing rod is located at one side of the area a when the drug-dialing rod rotates, so as to ensure that the drug-dialing rod sweeps the whole area a. The medicine poking rod integrally rotates along a first direction in a straight line. The medicine poking rod pokes the medicines with proper quantity from the area A of the medicine distribution working area to the area B of the medicine distribution working area. The first direction may be a clockwise direction or a counterclockwise direction, which is not limited herein.

In one example, before the medicine dispensing robot controls the medicine poking rod to rotate along the first direction, the medicine poking speed of the medicine poking rod is determined according to the type of the medicine.

Step 304: and judging whether the dialed medicine is arranged in a preset shape.

Specifically, if the dispensing robot determines that the medicines are not arranged in the preset configuration, for example, a straight line, step 305 is performed, and if the dispensing robot determines that the medicines are arranged in the preset configuration, step 306 is performed.

Step 305: and judging whether the medicine poking rod reaches the rotation stop position.

Specifically, because be equipped with vertical through-hole in dividing the medicine workspace, when dialling the medicine pole and change back to vertical through-hole, can lead to the medicine of dialling to drop from vertical through-hole. Therefore, in order to avoid the falling of the medicine, the medicine distribution robot is marked with a rotation stop position in the medicine distribution working area. If the medicine poking rod reaches the rotation stop position, step 306 is executed, and if the medicine poking rod does not reach the rotation stop position, step 303 is continuously executed.

It should be noted that, as will be understood by those skilled in the art, step 304 and step 305 in the present embodiment may be selectively implemented, and are not necessary steps in the present embodiment.

Step 306: the medicine poking rod is controlled to stop rotating.

Step 307: the number of medicines dialed out is identified based on the image taken by the camera module.

Step 308: and judging whether the number of the dialed medicines is less than or equal to the target number.

Specifically, if it is determined that the number of medicines to be dialed is equal to or less than the target number, step 309 is executed, otherwise, step 311 is executed.

Step 309: the rotary tray is controlled to rotate to a third preset position, and a medicine poking rod of the medicine distribution robot is controlled to poke the poked medicine to the first preset position. When the rotating tray rotates to a third preset position, the medicine taking cup is positioned below the longitudinal through hole; the first preset position is the position of the longitudinal through hole.

Optionally, before controlling the medicine dispensing rod of the medicine dispensing robot to dispense the dispensed medicine to the first preset position, the method further includes: controlling the rotating tray to rotate to a third preset position; when the rotary tray is located at the third preset position, the medicine taking cup of the medicine distribution robot is located below the longitudinal through hole.

Specifically, the dispensing robot controls the rotary tray to descend to the rotation position, as shown in fig. 18 a. The medicine dispensing robot controls the rotary tray to rotate to a third preset position, and when the rotary tray is located at the third preset position, the medicine taking cup is located below the longitudinal through hole, as shown in fig. 18 b. The dispensing robot controls the rotary tray to ascend to the dispensing position as shown in fig. 18 c. The medicine poking rod pokes the separated medicines to the position of the longitudinal through hole, so that the separated medicines fall into the medicine taking cup. After dispensing is completed, the dispensing robot controls the rotary tray to descend to the rotating position, as shown in fig. 18 d.

It should be noted that fig. 18a to 18d illustrate the lifting process of the medicine cup and the medicine cup by taking the medicine taking cup and the medicine storage cup as an example, and in practice, the lifting of the medicine storage cup or the medicine taking cup may be controlled independently.

Step 310: it is determined whether the number of medicines dialed is equal to the target number. If the number of the medicines to be dialed is determined to be equal to the target number, the medicine distribution process is ended, and if the number of the medicines to be dialed is determined not to be equal to the target number, the step 301 is executed again.

Step 311: based on the image of shooting the module shooting, the preceding driving lever and the back driving lever of control group medicine pole remove, draw from dividing medicine tray and get the medicine.

In one example, the medicine dispensing robot determines a first angle and a second angle based on an image shot by the shooting module; controlling the medicine poking rod to rotate by a first angle along a second direction; wherein the second direction is opposite to the first direction; the front shifting rod of the medicine shifting rod is controlled to rotate a second angle along the first direction; the medicine poking rod is controlled to rotate along the first direction to scratch and take the medicine. If the first direction is clockwise, the second direction is anticlockwise; if the first direction is counterclockwise, the second direction is clockwise.

Specifically, if the number of medicines dialed by the medicine dialing rod is larger than the target number, the front dialing rod and the rear dialing rod are matched to dispense medicines. As shown in fig. 19a, under the guidance of the visual system, the front shifter lever and the rear shifter lever are first driven by the main joint to rotate by a first angle along a second direction, that is, the current rotation direction is opposite to the rotation direction of the medicine pulling rod during the medicine pulling process described in step 303. Then, the auxiliary joint drives the front shifting lever to rotate by a second angle along the first direction, that is, the rotation direction is the same as the rotation direction of the medicine shifting rod in the medicine shifting process described in step 303, so that the front shifting lever and the rear shifting lever form a certain angle. Finally, the secondary joint is immobilized and the primary joint is rotated in the forward direction to complete the dispensing, as shown in FIG. 19 b.

Alternatively, determining the first angle and the second angle based on the image photographed by the photographing module includes: determining medicine dialing information according to the image shot by the shooting module; the medicine dialing information comprises any one or any combination of a distribution area of the medicines, a volume of the medicines, the number of the medicines and a target number; determining a first angle according to the medicine dialing information and a third constraint relation between the medicine dialing information and the first angle; and determining the second angle according to the medicine dialing information and the fourth constraint relation between the medicine dialing information and the second angle.

Step 312: and controlling the rotary tray to rotate to a second preset position or a fourth preset position, and controlling the medicine poking rod to rotate to a first preset position along the direction of the rest medicines. Step 309 is then performed.

Specifically, when the rotary tray is located at the fourth preset position, the waste medicine cup of the medicine distribution robot is located below the longitudinal through hole. The auxiliary joint drives the front deflector rod to rotate along a second direction, so that the front deflector rod and the rear deflector rod are aligned again. As shown in fig. 20 a. Then, the main joint drives the drug-pulling rod to rotate along the second direction, and the redundant drugs are pulled back to the drug storage cup, as shown in fig. 20b and 20 c. And finally, the control module controls the rotary tray to rotate to a third preset position, and controls the medicine poking rod to poke the poked medicine to the position of the longitudinal through hole. For example, as shown in fig. 21 a-21 c, the drug-dialing rod is rotated in a first direction to dial the dialed medicine to the location of the longitudinal through hole. For another example, as shown in fig. 22 a-22 c, the drug-dialing rod is rotated along the second direction to dial the dialed medicine to the position of the longitudinal through hole.

Optionally, before the medicine poking rod is controlled to rotate to the first preset position along the direction of the rest medicines, the medicine distribution robot controls the front poking rod to rotate by a second angle along the second direction.

It should be noted that, as those skilled in the art can understand, step 312 in this embodiment can be selectively implemented, and step 312 is not a necessary step of this embodiment. If step 312 is not performed, after step 311 is not performed, step 309 is performed.

In one embodiment, as shown in fig. 23, a visual dispensing method performed by a dispensing robot includes the following steps. Here, steps 401 to 412 are substantially the same as steps 301 to 312 of the visual medicine dispensing method shown in fig. 15, and are not repeated here.

Step 401: a target quantity of the drug is obtained.

Step 402: the rotary tray of the medicine distribution robot is controlled to rotate to a second preset position, and the first push rod is controlled to push the movable cup bottom of the medicine storage cup to move upwards.

Step 403: the medicine poking rod is controlled to rotate along the first direction.

Step 404: and judging whether the dialed medicine is arranged in a preset shape or not.

Specifically, if the control module determines that the medicine is not arranged in the predetermined shape, for example, a straight line, step 405 is executed, and if the control module determines that the medicine is arranged in the predetermined shape, step 406 is executed.

Step 405: and judging whether the medicine poking rod reaches the rotation stop position.

Specifically, step 406 is executed if the drug-dialing rod reaches the rotation stop position, and step 403 is executed if the drug-dialing rod does not reach the rotation stop position.

Step 406: the medicine poking rod is controlled to stop rotating.

Step 407: the number of medicines dialed out is identified based on the image taken by the camera module.

Step 408: and judging whether the number of the dialed medicines is less than or equal to the target number.

Specifically, if it is determined that the number of medicines to be dialed is equal to or less than the target number, step 409 is executed, otherwise, step 411 is executed.

Step 409: the rotary tray is controlled to rotate to a third preset position, and a medicine poking rod of the medicine distribution robot is controlled to poke the poked medicine to the first preset position. When the rotating tray rotates to a third preset position, the medicine taking cup is positioned below the longitudinal through hole; the first preset position is the position of the longitudinal through hole.

Step 410: it is determined whether the number of medicines dialed is equal to the target number. If the number of the medicines to be dialed is determined to be equal to the target number, the medicine distribution process is ended, and if the number of the medicines to be dialed is determined not to be equal to the target number, the step 401 is executed again.

Step 411: based on the image of shooting the module shooting, the preceding driving lever and the back driving lever of control group medicine pole remove, draw from dividing medicine tray and get the medicine.

Step 412: and controlling the rotary tray to rotate to a second preset position, and controlling the medicine poking rod to rotate to a first preset position along the direction of the rest medicines.

Step 413: the number of the scribed medicines is identified based on the image photographed by the photographing module.

Step 414: it is determined whether the number of scored drugs is equal to the target number.

Specifically, if the dispensing robot determines that the number of the medicines to be dispensed is equal to the target number, step 415 is performed, otherwise, step 416 is performed.

Step 415: and controlling the rotary tray to rotate to a third preset position, and controlling the medicine poking rod to poke the scratched medicine to the first preset position. The flow is then ended.

Step 416: it is determined whether the number of the drawn medicines is smaller than the target number.

Specifically, if the control module determines that the number of the medicines to be drawn is smaller than the target number, the control module executes step 417, otherwise, executes step 411.

Step 417: and controlling the rotary tray to rotate to a third preset position, and controlling the medicine poking rod to poke the scratched medicine to the first preset position. Step 401 is then performed.

It should be noted that steps 401 to 417 are a one-time dispensing process, and when the process returns from step 417 to step 401, the dispensing robot starts the next dispensing process of the current medicine. At this time, the medicine dispensing robot acquires the sum of the target number of medicines = the number of medicines that the user needs to take-the number of medicines that are drawn to the medicine taking cup each time; alternatively, the target number of drugs = target number in the previous dispensing process-number of drugs dispensed to the dispensing cup in the previous dispensing process.

In this embodiment, the idea of "divide-and-conquer" (break one by one) can make up for the inaccuracy of the dispensing result caused by the low precision of the hardware of the dispensing robot. Namely, the accuracy of the dispensing result is improved by continuous repetition.

In one embodiment, the vision system, including the camera and vision algorithms, may also perform operations including, but not limited to:

Specifically, when pushing up the medicine, vision system can shoot the image of branch medicine workspace to send to control module or high in the clouds, control module or high in the clouds can predict the quantity that exceeds the planar medicine of branch medicine tray place according to the shape and the accumulational form of the medicine in the image, and control module or high in the clouds is based on the quantity of the planar medicine of branch medicine tray place, and the first push rod of control stops promoting.

And operation 4: the vision system shoots the image of the interior of the medicine taking cup and confirms whether the number of the taken medicines is correct or not based on the image of the interior of the medicine taking cup. Alternatively, an image of the interior of the dispensing cup may be saved as a record.

Operation 5: in the first medicine distributing process, before the dialed medicine is placed in the medicine taking cup, whether the medicine taking cup is empty or not is confirmed. If the medicine taking cup is not empty, the medicine which is separated last time may not be eaten, and the medicine taking cup is emptied by operating the second push rod and the medicine pulling rod.

And operation 6: the vision system has a medicine identification function. When the medicines in the medicine taking cup are not taken, the medicines in the medicine taking cup can be pushed to the medicine distribution tray, and then the medicines are identified based on the characteristics of the medicines such as shape and color. Optionally, in order to improve the identification efficiency, other medicine detection efforts, such as a raman spectrum detector, may be added to the medicine dispensing robot. Based on the identification result, the medicine is separated out through the medicine poking rod and is respectively poked into the corresponding medicine storage cups.
