Description

Technical Field

[0001] The present invention relates to the technical field of drug transportation, and in particular to an automated medical logistics transportation system and method. Background Art

[0002] Medical logistics delivery systems play a vital role in the medical field. Their main purpose is to achieve efficient and accurate transportation of medicines, medical devices and other materials within hospitals to ensure the smooth progress of medical services.

[0003] At present, drugs are delivered from storage points such as pharmacies or drug warehouses according to the needs of departments. When manually transporting, staff receive a list of drug needs, go to the storage point to pick up the drugs, and then push the drugs to various departments through corridors, elevators and other channels. However, manual transportation is slow and staff need to spend a lot of time on the road. Especially in large hospitals, departments are widely distributed and the building structure is complex. Manual distribution may need to cross multiple areas, resulting in long drug transportation time. Secondly, during the transportation process, due to the instability of manual operation, drugs are easily affected by bumps, collisions, etc. In particular, some fragile drugs or drugs that require special storage conditions may be damaged due to improper operation during manual transportation, affecting the quality of the drugs and even having a negative impact on the treatment effect of patients. Therefore, an automated medical logistics transportation system and method are proposed. Summary of the invention

[0022] The route marking module is used to analyze the maximum transportation speed based on the identified drug data combined with the shapes of multiple sections of track that the transportation needs to pass through, and obtain the maximum speed at which the transport vehicle can travel safely in each section of track.

[0023] As a further improvement of the technical solution, the safety buffer rate acquisition unit extracts according to the speed change of the transport trolley, monitors the moving speed of the transport trolley when the transport trolley departs from the drug storage point, stops monitoring when the moving speed of the transport trolley reaches the maximum drivable speed of the track, and saves the image data of the process;

[0024] When the image data shows that the drug is at risk of tilting and being damaged during the monitoring process, the acceleration rate is immediately reduced.

[0025] As a further improvement of the technical solution, the safety buffer rate acquisition unit includes a drug determination module and a safety buffer rate analysis module;

[0026] The drug determination module is used to perform type analysis based on the drug data obtained by the drug identification module to obtain drugs in the transport trolley that may be damaged due to tilting;

[0027] The safety buffer rate analysis module is used to extract the moving speed of the transport cart at the same time node according to the time node of the extracted image data, and perform buffer rate analysis in combination with the image data to obtain the buffer rate of each drug under the safe and non-tilted condition, and then comprehensively extract the buffer rate of each drug, and use the minimum buffer rate as the safety buffer rate corresponding to the transport cart's transportation this time.

[0028] As a further improvement of the technical solution, the buffer area setting unit includes a buffer area analysis module and a buffer area positioning module;

[0029] The buffer area analysis module is used to perform buffer area analysis based on the safety buffer rate combined with the maximum speed of the track where the transport trolley is located and the maximum speed of the lower track to obtain the length of the buffer area between the two tracks;

[0030] The buffer area positioning module is used to divide the buffer area according to the speed of the track combined with the speed of the lower track and the safety buffer rate when the lower track of the transport trolley needs to be accelerated, and the starting point of the buffer area is set at the starting point of the lower track. Conversely, when the lower track of the transport trolley needs to be decelerated, the buffer area is divided according to the speed of the track combined with the speed of the lower track and the safety buffer rate, and the end point of the buffer area is set at the starting point of the lower track, limiting the speed change of the transport trolley within the safety buffer area until the drug transportation is completed.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1 As shown, one of the purposes of the present invention is to provide an automated medical logistics transportation system, including a transmission establishment unit 10, a route planning unit 20, a transportation route speed marking unit 30, a safety buffer rate acquisition unit 40 and a buffer area setting unit 50;

[0043] The transmission establishment unit 10 is used to establish a drug transmission management terminal so that the transmission vehicle can move to each department and drug storage point and parking point through the track;

[0044] The transmission establishment unit 10 installs a transport track between each department and drug storage point in the hospital, extends and installs a parking point in the transport track, and then installs a corresponding transport trolley. The transport trolley can move to each department, drug storage point, and parking point through the track, and the transport trolley is parked at the parking point when idle;

[0045] The transport track is composed of multiple sections of track spliced ​​together;

[0046] The drug delivery management terminal is used to receive the drug needs of each department, and then send the drug needs to the drug storage point, so that the doctor can place the corresponding drugs in the transport vehicle according to the drug needs.

[0047] The route planning unit 20 is used to divide the track into sections according to different connection points, determine the drug transportation task, select the nearest transport vehicle for route planning according to the drug transportation task, and obtain multiple sections of track that the transportation needs to pass through;

[0048] The route planning unit 20 includes a track segmentation module and a route planning module;

[0049] The track segmentation module is used to segment the track according to different connection points, divide the transport track into multiple sections, and number each section individually;

[0050] The transport track is divided into multiple sections according to the connection points, and each section is individually numbered. Digital numbers or a combination of letters and numbers can be used to facilitate accurate identification and distinction.

[0051] The route planning module is used to collect drug transport tasks at the drug transport management end, and select the transport vehicle closest to the drug storage point for route planning based on the drug transport task. After obtaining the real-time position of the transport vehicle and arriving at the drug storage point, it will go through multiple tracks to the target department. The specific steps are as follows:

[0052] Drug transport task collection: The drug transport management end collects drug transport tasks issued by various departments of the hospital in real time, including drug name, quantity, target department and other information. The management end collects drug transport tasks according to the location of the drug storage point;

[0053] Transport vehicle selection: Calculate the distance between each idle transport vehicle and the drug storage point. The distance is calculated based on the actual path length of the track, and the idle transport vehicle closest to the drug storage point is selected to perform the drug transportation task.

[0054] Route planning and execution: determine the real-time location of the selected transport vehicle, plan the route for the transport vehicle to reach the drug storage point from the current location, determine the numbers of the multiple sections of track that need to be passed, and after the transport vehicle arrives at the drug storage point, load the drugs, and plan the route to the target department again, clarifying the multiple sections of track that need to be passed.

[0055] When the route planning module selects a transport vehicle, the transport vehicle must be in an idle state;

[0056] The transfer trolley is in working state when transporting medicines;

[0057] The transport vehicle is in an idle state when it is parked at a parking point or on the way back to the parking point, so that it can be selected when there is a new drug transportation task.

[0058] The transport route speed labeling unit 30 is used to obtain image data inside the transport vehicle, identify the medicine according to the image data, analyze the maximum speed of the identified medicine in combination with the multiple sections of track through which the transportation needs to pass, and label the transport route of the transport vehicle according to the acquired speed;

[0059] The transport route speed labeling unit 30 includes a drug identification module and a route labeling module;

[0060] The drug identification module is used to install a camera inside the transport vehicle to obtain real-time image data inside the transport vehicle, collect drug picture data at the same time, and combine the drug image data with the image data for drug identification. The data of the drugs transported in the transport vehicle is obtained based on the image data. The specific steps are as follows:

[0061] Hardware installation: According to the space and light conditions inside the transport vehicle, select a low-light, wide-angle HD camera and install it in the center of the roof or above the drug placement area to ensure that the full view of the drugs in the vehicle can be clearly captured;

[0062] Image data acquisition: When the transport vehicle starts, the camera is also started to collect image data in the vehicle in real time. The camera transmits the collected image data to the drug transport management end through the network connection, and then the drug transport management end stores the received image data in chronological order;

[0063] Drug image data collection: Establish a drug image database that includes standard images of commonly used drugs in hospitals. These images can be captured when the drugs are put into storage to ensure that the images clearly and accurately display the appearance characteristics of the drugs, including packaging, labels, shapes, colors, etc. Then, use the image matching algorithm to compare and combine the real-time internal image data of the transport vehicle with the standard images in the drug image database to find the standard image that is most similar to the drug in the collected image. Finally, based on the results of image matching, determine the name, specifications and other information of the drugs transported in the transport vehicle to obtain drug data.

[0064] The route marking module is used to analyze the maximum transportation speed based on the identified drug data and the shapes of multiple sections of tracks that need to be transported, and obtain the maximum speed at which the transport vehicle can travel safely in each section of track. The specific steps are as follows:

[0065] Let the length of the track be L, the number of curves be n, the radius of the curve be r, and the slope be θ;

[0066] Based on the identified drug data, determine the physical properties of the drug and set a safety factor S for different types of drugs. For very fragile drugs, the value is 0.5, for ordinary solid drugs, the value is 1, and for liquid drugs, the value is between 0.6-0.8 according to their packaging and stability;

[0067]

[0068] Among them, according to the centripetal force formula in physics, F is the centripetal force, m is the total mass of the transport trolley and the medicine, v is the speed, and r is the radius of the curve. In order to ensure the safe driving of the transport trolley on the curve, the centripetal force cannot exceed the friction between the tires of the trolley and the track. The maximum static friction is Fmax , in the case of horizontal curve, F max =αmg, where α is the friction coefficient and g is the acceleration due to gravity;

[0069] When F = F max The maximum safe speed on the curve can be obtained when

[0070] Combined with the drug safety factor, the actual maximum safe speed on the curve is v bend-actual =v bend ×S;

[0071] When the transport vehicle is traveling on a sloped track, it is necessary to consider the component of gravity along the track. According to Newton's second law F = ma, in the direction of the slope, mgsinθ-F friction =ma, where a is the acceleration, F friction is the friction force, F friction =αmg cosθ;

[0072] For safe driving, the acceleration a cannot exceed a certain value. Assume that the safe acceleration is a safe , the formula is as follows:

[0073] mgsinθ-αmg cosθ=ma safe

[0074] The maximum safe speed v on the slope can be solved slope , when the initial velocity is 0, then according to the motion formula Among them, L slope is the length of the slope;

[0075] Combined with the drug safety factor, the actual maximum safe speed of the slope is v slope-actual =v slope ×S.

[0076] The safety buffer rate acquisition unit 40 is used to determine the tilted and damaged medicines when the transport vehicle departs from the medicine storage point, and then extract the image data of such medicines, extract the moving speed at the same time node according to the time node of the image data, and combine it to perform buffer rate analysis, so as to determine the safety buffer rate of the transport vehicle;

[0077] The safety buffer rate acquisition unit 40 extracts the speed change of the transport vehicle. When the transport vehicle departs from the drug storage point, the moving speed of the transport vehicle is monitored. When the moving speed of the transport vehicle reaches the maximum drivable speed of the track, the monitoring is stopped and the image data of the process is saved.

[0078] When the image data shows that the drug is at risk of tilting and damage during the monitoring process, the acceleration rate is immediately reduced;

[0079] By continuously analyzing the image data collected by the camera inside the transport vehicle, image recognition algorithms can be used to detect whether the medicine is tilted or otherwise damaged. For example, the tilt of the medicine can be determined by detecting whether the edge of the medicine package is at a large angle to the horizontal direction. When a risk is detected, the acceleration rate is immediately reduced.

[0080] The safety buffer rate acquisition unit 40 includes a drug determination module and a safety buffer rate analysis module;

[0081] The drug determination module is used to perform type analysis based on the drug data obtained by the drug identification module, and obtain drugs that may be damaged due to tilting in the transport trolley;

[0082] Drugs can be classified based on their physical properties, packaging characteristics, stability, etc., and divided into different types such as solid drugs, liquid drugs, and fragile drugs. Factors to be considered include the fragility of the drugs, the impact resistance of the packaging, the internal structure of the drugs, etc. Through a comprehensive evaluation of these factors, it can be determined which drugs will be damaged due to tilting.

[0083] The safety buffer rate analysis module is used to extract the moving speed of the transport vehicle at the same time node according to the time node of the extracted image data, and perform buffer rate analysis in combination with the image data to obtain the buffer rate of each drug under the condition of safety and no tilt, and then comprehensively extract the buffer rate of each drug, and use the minimum buffer rate as the safety buffer rate corresponding to the transport vehicle for this transportation. The formula is as follows:

[0084] P = ul

[0085] Where P is the impact force, u is the mass of the drug, and l is the acceleration, which can be calculated by the speed change of the transport trolley and time;

[0086] In order to prevent the medicine from being damaged when tilted, the impact force P cannot exceed the bearing capacity of the medicine packaging. Suppose the maximum bearing capacity of the medicine packaging is P max , then P≤P max ,According to this condition, the required buffering rate can be derived;

[0087] Assume that the speed of the drug needs to be reduced from the current speed x to the safe speed x within time t. safe , then the acceleration Then substitute it into P = ul, and we get Finally, the range of the buffering rate is obtained by solving this inequality.

[0088] The buffer area setting unit 50 is used to perform a buffer area analysis based on the safe buffer rate in combination with the track where the transport trolley is located. When the lower track of the transport trolley needs to be accelerated, a buffer area is set at the lower track. Conversely, when the lower track of the transport trolley needs to be decelerated, a buffer area is set at the track to limit the speed change of the transport trolley to within the safe buffer rate.

[0089] The buffer area setting unit 50 includes a buffer area analysis module and a buffer area positioning module;

[0090] The buffer area analysis module is used to perform buffer area analysis based on the safe buffer rate combined with the maximum speed of the track where the transport trolley is located and the maximum speed of the lower track to obtain the length of the buffer area between the two tracks. The specific steps are as follows:

[0091] K1≥k2, considered as deceleration state:

[0092]

[0093] K1<k2, regarded as acceleration state:

[0094]

[0095] Among them, H is the length of the buffer area, k1 is the maximum speed of the current track of the transport trolley, k2 is the maximum speed of the lower track, and a is the safety buffer rate.

[0096] The buffer area positioning module is used to divide the buffer area according to the speed of the track combined with the speed of the lower track and the safety buffer rate when the lower track of the transport trolley needs to be accelerated, and the starting point of the buffer area is set at the starting point of the lower track. Conversely, when the lower track of the transport trolley needs to be decelerated, the buffer area is divided according to the speed of the track combined with the speed of the lower track and the safety buffer rate, and the end point of the buffer area is set at the starting point of the lower track, limiting the speed change of the transport trolley within the safety buffer area until the drug transportation is completed.

[0097] The second object of the present invention is to provide an automated medical logistics delivery method, including any one of the automated medical logistics delivery systems described above, comprising the following steps:

[0098] S1. Establish a drug transport management terminal so that the transport vehicle can move to each department and drug storage and parking points through the track;

Determine the drug transportation task, select the nearest transport vehicle for route planning according to the drug transportation task, obtain multiple sections of track that the transportation needs to pass through, analyze the maximum speed of the multiple sections of track that need to be passed through, and mark the transportation route of the transport vehicle according to the obtained speed;

[0100] S3. Extract the moving speed of the same time node according to the time node of the image data and combine it for buffer rate analysis, so as to determine the safe buffer rate for the transport trolley, perform buffer area analysis based on the safe buffer rate combined with the track where the transport trolley is located, and complete the setting of the buffer area.
