[0073] Example 3

[0074] like Figure 1As shown, a hospital drug management system based on digitization includes a database, an algorithm module, a control module and a positioning module. The database is used to store basic information, inventory information and expiration information of drugs; the algorithm module includes a drug storage optimization algorithm, a pick-and-place path planning algorithm and an inventory early warning algorithm; the control module is used to control the operation of the pick-and-place device according to the calculation results of the algorithm module; the positioning module is used to locate and record the location information of each drug, so as to facilitate the control of the pick-and-place device to accurately pick and place the drug.

[0075] The drug storage optimization algorithm in the algorithm module is as follows: define the comprehensive priority P of the drug, and the calculation formula is:

[0076]

[0077] Among them, F is the frequency of drug use, which is obtained by counting the number of times the drug is taken within a certain period of time; V is the volume of the drug, V max It is the largest storage compartment in the medicine cabinet; T exp is the expiration date of the drug, T now is the current time; α, β, γ are weight coefficients, and α+β+γ=1; the drugs are sorted according to their comprehensive priority P, and the drugs with high priority are preferentially allocated to the storage compartments close to the access port.

[0078] The pick-and-place path planning algorithm in the algorithm module selects the optimal path by evaluating the cost function f(n) of each node. The calculation formula of the cost function f(n) is:

[0079] f(n)=g(n)+h(n)

[0080] Among them, g(n) is the actual cost from the starting node to the current node n, that is, the distance moved by the longitudinal track 2 and the installation frame 6; h(n) is the estimated cost from the current node n to the target node, which is estimated using the Manhattan distance;

[0081] The inventory warning algorithm in the algorithm module is used to monitor the inventory quantity of drugs in real time. When the drug inventory is lower than the set threshold, an early warning is issued in time. The specific formula is:

[0082]

[0083] Among them, S wnrning is the inventory warning threshold, U is the average usage of the drug within a certain period of time, and λ is the warning coefficient, which is adjusted according to factors such as the importance of the drug and the stability of supply.

[0084] Working principle: first install the transverse track 1 on the top and bottom of the medicine cabinet, then connect the transverse drive assembly 3 with the longitudinal track 2, and install the drive screw 4 inside the longitudinal track 2, and install the longitudinal drive assembly 5 at the bottom of the longitudinal track 2, so that the longitudinal drive assembly 5 and the drive screw 4 are meshed. Then fix the longitudinal track 2 between the two transverse tracks 1; and install the electric push rod 7 in the installation frame 6, and then fix the electric suction cup 9 and the barcode scanner 10 with the structure of the installation plate 8 at the output end of the electric push rod 7. Build a management system, including the software installation and configuration of the database server, algorithm module, control module and positioning module. Enter the basic information of the medicine, initial inventory information, etc. into the database. Debug the system to test the movement accuracy of the longitudinal track 2 and the installation frame 6, the scanning accuracy of the barcode scanner 10, the positioning accuracy of the positioning module, and whether the various functions of the management system are normal. When there is a demand for taking and placing medicines, the management system receives the medicine collection information and determines the storage location of the medicine according to the medicine storage optimization algorithm. The control module plans the optimal pick-and-place path for the longitudinal track 2 and the electric push rod 7 according to the pick-and-place path planning algorithm, and sends control instructions to the lateral drive component 3 and the longitudinal drive component 5. The longitudinal track 2 and the electric push rod 7 move to the drug storage position according to the planned path, use the barcode scanner 10 to scan the barcode or QR code of the drug, and after confirming that the drug information is correct, the electric push rod 7 cooperates with the electric suction cup 9 to perform the pick-and-place operation. After the pick-and-place operation is completed, the management system updates the inventory information in the database and monitors the drug inventory in real time according to the inventory warning algorithm. When the drug inventory is lower than the warning threshold, the system issues a warning message to remind the staff to replenish the stock in time.

[0085] To sum up, compared with the prior art, the present application can reasonably allocate drug storage locations and plan the optimal picking and placing paths through the drug storage optimization algorithm and the picking and placing path planning algorithm, which greatly shortens the time for picking and placing drugs and improves the work efficiency of the hospital pharmacy; at the same time, with the cooperation of the transverse track 1 and the longitudinal track 2, the mounting frame 6 cooperates with the structure of the electric push rod 7 to move back and forth in front of the medicine cabinet, and the electric push rod 7 cooperates with the electric suction cup 9 to pick and place drugs inside the medicine cabinet, thereby facilitating the fastest way to pick and place drugs through the management system.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
