Description

Technical Field

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

[0002] Medical logistics transportation systems play a crucial role in the medical field. Their main purpose is to achieve efficient and accurate transportation of materials such as drugs and medical devices within a hospital to ensure the smooth progress of medical services.

[0003] Currently, drugs are dispatched from storage points such as pharmacies or drug warehouses according to the needs of departments. When manually transporting, after receiving a drug demand list, staff go to the storage point to pick up the drugs and then push the drugs through passages such as corridors and elevators to each department. However, manual transportation is slow, and staff need to spend a lot of time on the way. Especially in large hospitals, departments are widely distributed and the building structure is complex. Manual distribution may require passing through multiple areas, resulting in long drug transportation times. Secondly, during the handling process, due to the instability of manual operations, drugs are easily affected by jolts, collisions, etc. Especially for some fragile drugs or drugs that require special storage conditions, they may be damaged due to improper operations during manual handling, affecting the quality of drugs and even potentially 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

[0004] The purpose of the present invention is to provide an automated medical logistics transportation system and method to solve the problems raised in the above background art.

[0005] To solve the above technical problems, one of the purposes of the present invention is to provide an automated medical logistics transportation system, including a transmission establishment unit, a route planning unit, a transportation route speed marking unit, a safety buffer rate acquisition unit, and a buffer area setting unit;

[0006] The transmission establishment unit is used to establish a drug transmission management terminal, enabling the transmission trolley to move to each department, drug storage point, and parking point through the track;

[0007] The route planning unit is used to segment the track according to different connection points, and at the same time determine the drug transportation task, select the nearest transmission trolley according to the drug transportation task for route planning, and obtain multiple segments of the track that need to be passed during transportation;

[0008] The transportation route speed marking unit is used to obtain the image data inside the transmission trolley, identify the drugs according to the image data, analyze the maximum speed based on the identified drugs and the multiple segments of the track that need to be passed during transportation, and mark the transportation route of the transmission trolley according to the obtained speed;

[0009] The safety buffer rate acquisition unit is used to determine damaged drugs due to tilting when the transport trolley departs from the drug storage point, then extract the image data of such drugs, extract the moving speed at the same time node according to the time node of the image data, and combine them for buffer rate analysis, so as to determine the safety buffer rate for the transport trolley;

[0010] The buffer area setting unit is used to perform buffer area analysis according to the safety buffer rate in combination with the track where the transport trolley is located. When the lower section of the track of the transport trolley needs to be speeded up, a buffer area is set at the lower section of the track. On the contrary, when the lower section of the track of the transport trolley needs to be decelerated, a buffer area is set at the track where it is located, restricting the speed change of the transport trolley within the safety buffer rate.

[0011] As a further improvement of this technical solution, the transmission establishment unit installs transport tracks between each department in the hospital and the drug storage point, extends and installs parking points in the transport tracks, and then installs transport trolleys correspondingly. The transport trolleys can move to each department, the drug storage point, and the parking points through the tracks, and the transport trolleys are parked at the parking points when idle;

[0012] The transport track is composed of multiple sections of tracks spliced together;

[0013] The drug transmission management terminal is used to receive the drug requirements of each department, and then send the drug requirements to the drug storage point, so that doctors can place the corresponding drugs in the transport trolley according to the drug requirements.

[0014] As a further improvement of this technical solution, the route planning unit includes a track segmentation module and a route planning module;

[0015] The track segmentation module is used to segment the transport track into multiple sections of tracks according to different connection points of the tracks, and number each section of the track separately;

[0016] The route planning module is used to collect drug transportation tasks at the drug transmission management terminal, and select the transport trolley closest to the drug storage point according to the drug transportation tasks for route planning. After obtaining the real-time position of the transport trolley to reach the drug storage point, it then obtains the multiple sections of tracks that need to be passed to reach the target department.

[0017] As a further improvement of this technical solution, when the route planning module selects a transport trolley, the transport trolley needs to be in an idle state;

[0018] When the transport trolley is transporting drugs, it is in a working state;

[0019] When the transport trolley is parked at the parking point and on the way back to the parking point, it is in an idle state.

[0020] As a further improvement of this technical solution, the transportation route speed marking unit includes a drug identification module and a route marking module;

[0021] The drug identification module is used to install a camera inside the transport trolley to obtain real-time image data inside the transport trolley, collect picture data of the drugs at the same time, combine the drug image data and the image data for drug identification, and obtain the drug data transported in the transport trolley according to the image data;

[0022] The route marking module is used to analyze the maximum transportation speed according to the identified drug data and the shapes of multiple sections of tracks that the transportation needs to pass through, and obtain the maximum speed that the transport trolley can travel safely in each section of the track.

[0023] As a further improvement of this technical solution, the safety buffer rate acquisition unit extracts according to the speed change of the transport trolley. When the transport trolley departs from the drug storage point, the moving speed of the transport trolley is monitored. When the moving speed of the transport trolley reaches the maximum speed that can be traveled on this track, the monitoring stops, and the image data of this process is saved;

[0024] When the image data shows a risk of the drug tilting and being damaged during the monitoring process, immediately reduce the acceleration rate.

[0025] As a further improvement of this 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 according to the drug data obtained by the drug identification module to obtain the drugs in the transport trolley that will be damaged due to tilting;

[0027] The safety buffer rate analysis module is used to extract the moving speed of the transport trolley at the same time node according to the time node of the extracted image data, and combine it with the image data for buffer rate analysis to obtain the buffer rate in the case of no tilting of each drug. Then, the buffer rates of each drug are comprehensively extracted, and the minimum buffer rate is used as the safety buffer rate corresponding to this transport of the transport trolley.

[0028] As a further improvement of this 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 according to the safety buffer rate, the maximum speed of the track where the transport trolley is located, and the maximum speed of the next track, and obtain the buffer area length between the two tracks;

[0030] The buffer area positioning module is used to divide the buffer area according to the speed of the current track, the speed of the lower track and the safety buffer rate when the lower track of the transfer cart needs to be accelerated, and set the starting point of the buffer area at the starting point of the lower track. On the contrary, when the lower track of the transfer cart needs to be decelerated, the buffer area is divided according to the speed of the current track, 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, restricting the speed change of the transfer cart within the safe buffer area until the drug transportation is completed.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figure 1 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 trolley can move to each department, drug storage point, and parking point through the track;

[0044] The transmission establishment unit 10 installs transportation tracks between each department and drug storage point in the hospital, and extends and installs parking points in the transportation tracks, and then correspondingly installs transportation trolleys. The transportation trolleys can move to each department, drug storage point, and parking point through the track, and the transportation trolleys are parked at the parking points when idle;

[0045] The transportation track is composed of multiple sections of tracks spliced together;

[0046] The drug transmission management terminal is used to receive the drug requirements of each department, and then send the drug requirements to the drug storage point, so that the doctor can place the corresponding drugs in the transportation trolley according to the drug requirements.

[0047] The route planning unit 20 is used to segment the track according to different connection points, and at the same time determine the drug transportation task, select the nearest transmission trolley according to the drug transportation task for route planning, and obtain multiple sections of tracks that need to be passed during transportation;

[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 transportation track according to different connection points of the track, divide the transportation track into multiple segments of tracks, and assign a separate number to each segment of track;

[0050] Dividing the transportation track into multiple segments of tracks according to the connection points and assigning a separate number to each segment of track can be done using numerical numbers or a combination of letters and numbers for accurate identification and differentiation.

[0051] The route planning module is used to collect drug transportation tasks at the drug transmission management terminal, select the transmission trolley closest to the drug storage point according to the drug transportation tasks for route planning. After obtaining the real-time position of the transmission trolley to reach the drug storage point, it then goes to the multiple segments of tracks required to reach the target department. The specific steps are as follows:

[0052] Collection of drug transportation tasks: The drug transmission management terminal collects the drug transportation tasks sent by each department of the hospital in real time, including information such as drug name, quantity, target department, etc. The management terminal determines according to the position of the drug storage point;

[0053] Selection of transmission trolley: Calculate the distance between each idle transmission trolley and the drug storage point. Among them, the distance is calculated according to the actual path length of the track, and select the idle transmission trolley closest to the drug storage point to execute the drug transportation task;

[0054] Route planning and execution: Determine the real-time position of the selected transmission trolley, plan the route for the transmission trolley to reach the drug storage point from the current position, determine the numbers of the multiple segments of tracks to pass through, and after the transmission trolley reaches the drug storage point, load the drugs and plan the route to the target department again, clarifying the multiple segments of tracks required to pass through.

[0055] When the route planning module selects a transmission trolley, the transmission trolley needs to be in an idle state;

[0056] When the transmission trolley transports drugs, it is in a working state;

[0057] When the transmission trolley parks at the parking point and returns to the parking point on the way, it is in an idle state to be selected when there are new drug transportation tasks.

[0058] The transportation route speed marking unit 30 is used to obtain the image data inside the transmission trolley, identify the drugs according to the image data, analyze the maximum speed according to the identified drugs in combination with the multiple segments of tracks required for transportation, and mark the transportation route of the transmission trolley according to the obtained speed;

[0059] The transportation route speed marking unit 30 includes a drug identification module and a route marking module;

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

[0061] Hardware installation: According to the space and light conditions inside the transport trolley, select a high-definition camera with low illuminance and wide angle, and install it at the center of the roof or above the area close to the drug placement area to ensure that the entire picture of the drugs inside the vehicle can be clearly captured;

[0062] Image data acquisition: When the transport trolley starts, start the camera at the same time to make it start to collect real-time image data inside the vehicle. The camera transmits the collected image data to the drug transmission management terminal through a network connection, and then the drug transmission management terminal stores the received image data in chronological order;

[0063] Drug image data collection: Establish a drug picture database containing standard pictures of commonly used drugs in hospitals. These pictures can be taken and collected when the drugs are put into storage to ensure that the pictures clearly and accurately show the appearance characteristics of the drugs, including packaging, labels, shapes, colors, etc. Then, use an image matching algorithm to compare and combine the real-time collected image data inside the transport trolley with the standard pictures in the drug picture database, find the standard picture that is most similar to the drug in the collected image, and finally, according to the result of the image matching, determine the drug name, specification and other information of the drugs transported inside the transport trolley, so as to obtain the drug data.

[0064] The route marking module is used to analyze the maximum transport speed according to the recognized drug data in combination with the shapes of multiple sections of tracks that need to be passed during transportation, and obtain the maximum speed that the transport trolley can travel safely in each section of the track. The specific steps are as follows:

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

[0066] According to the recognized drug data, determine the physical properties of the drugs, 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; for liquid drugs, according to their packaging and stability, the value ranges from 0.6 to 0.8;

[0067]

[0068] Among them, obtained according to the centripetal force formula in physics, F is the centripetal force, m is the total mass of the transport trolley and the drugs, v is the speed, r is the bend radius. To ensure the safe driving of the transport trolley on the bend, the centripetal force cannot exceed the friction force between the trolley tires and the track. Let the maximum static friction force be Fmax , in the case of a horizontal bend, 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 of the bend can be obtained

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

[0071] When the transport trolley travels on a sloped track, the component of gravity along the track direction needs to be considered. According to Newton's second law F = ma, in the direction along the slope, mgsinθ - F friction = ma, where a is the acceleration and F friction is the frictional force, and F friction = αmg cosθ;

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

[0073] mgsinθ - αmg cosθ = ma safe

[0074] The maximum safe speed v slope on the slope can be solved for the case where the initial velocity is 0, and then according to the motion formula where 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 inclined and damaged drugs when the transport trolley departs from the drug storage point, then extract the image data of this type of drug, extract the moving speed at 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 safety buffer rate for the transport trolley;

[0077] The safety buffer rate acquisition unit 40 extracts according to the speed change of the transport trolley. When the transport trolley departs from the drug storage point, the moving speed of the transport trolley is monitored. When the moving speed of the transport trolley reaches the maximum speed that can be traveled on this track, the monitoring is stopped, and the image data of this process is saved;

[0078] When the image data shows a risk of inclined and damaged drugs during the monitoring process, immediately reduce the acceleration rate;

[0079] By continuously analyzing the image data collected by the internal camera of the transport trolley, image recognition algorithms can be used to detect possible damage situations such as whether the drugs are tilted. For example, it can be determined whether the drugs are tilted by detecting whether the edge lines of the drug packaging have a large angle with 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 recognition module to obtain the drugs in the transport trolley that may be damaged due to tilting;

[0082] Classification can be carried out from aspects such as the physical properties, packaging characteristics, and stability of the drugs. The drugs can be divided into different types such as solid drugs, liquid drugs, and fragile drugs. The considerations include the fragility of the drugs, the impact resistance of the packaging, and the internal structure of the drugs. By comprehensively evaluating these factors, it is 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 trolley 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 in the case where each drug is safely not tilted. Then, the buffer rates of each drug are comprehensively extracted, and the minimum buffer rate is used as the safety buffer rate corresponding to this transport of the transport trolley. 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, and the acceleration can be calculated by the speed change and time of the transport trolley;

[0086] In order to prevent the drugs from being damaged when tilted, the impact force P cannot exceed the bearing capacity of the drug packaging. Let the maximum bearing force of the drug packaging be P max , then there is P ≤ P max , according to this condition, the required buffer rate can be deduced;

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

[0088] The buffer area setting unit 50 is used to analyze the buffer area according to the safety buffer rate in combination with the track where the transfer cart is located. When the lower track of the transfer cart needs to be speeded up, a buffer area is set at the lower track. Conversely, when the lower track of the transfer cart needs to be decelerated, a buffer area is set at the track where it is located, restricting the speed change of the transfer cart within the safety 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 analyze the buffer area according to the safety buffer rate in combination with the maximum speed of the track where the transfer cart is located and the maximum speed of the lower track, and obtain the length of the buffer area between the two tracks. The specific steps are as follows:

[0091] If K1≥k2, it is regarded as the deceleration state:

[0092]

[0093] If K1<k2, it is regarded as the acceleration state:

[0094]

[0095] Among them, H is the length of the buffer area, k1 is the maximum speed of the track where the transfer cart is currently located, 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 where it is located, the speed of the lower track, and the safety buffer rate when the lower track of the transfer cart needs to be speeded up, and set the starting point of the buffer area at the starting point of the lower track. Conversely, when the lower track of the transfer cart needs to be decelerated, the buffer area is divided according to the speed of the track where it is located, 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, restricting the speed change of the transfer cart 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 transportation method, including the automated medical logistics transportation system in any one of the above, including the following steps:

[0098] S1. Establish a drug transfer management terminal, so that the transfer cart can move to each department, drug storage point, and parking point through the track;

[0100] S3. Extract the moving speeds at the same time nodes according to the time nodes of the image data, combine them for buffer rate analysis, so as to determine the safety buffer rate for the transport trolley, analyze the buffer area according to the safety buffer rate in combination with the track where the transfer trolley is located, and complete the setting of the buffer area.
