Description

Technical Field

[0001] This invention relates to the field of medical waste management, and in particular to a medical waste management platform based on RFID technology. Background Technology

[0002] Medical waste, as a type of hazardous waste, is of great significance for environmental protection, public health, and the sustainable development of the medical industry. This type of waste may carry highly infectious pathogens such as bacteria, viruses, and fungi. Improper handling can easily lead to the spread of disease and threaten the health of nearby residents. Currently, most hospitals still rely mainly on manual visual sorting of medical waste, without sufficient intelligent equipment to assist them. This makes the sorting process inefficient, and there is no traceability mechanism for the entire medical waste treatment process. Once a problem occurs, it is impossible to find the root cause of the problem. RFID technology is a technology that uses radio frequency signals to achieve contactless information transmission through spatial coupling and uses the transmitted information to achieve the purpose of identification. It can be involved in the entire process of medical waste treatment and can realize the accurate classification and traceability of medical waste. To address this, a medical waste management platform based on RFID technology has been launched. Summary of the Invention

[0003] In view of this, the present invention provides a medical waste management platform based on RFID technology to solve the problems mentioned in the background.

[0004] The objective of this invention can be achieved through the following technical solution: a medical waste management platform based on RFID technology, comprising: Container deployment module: Used to deploy containers for storing medical waste in various departments of the hospital; Personnel registration module: Used for hospital medical personnel, collection personnel, and management personnel to register on the medical waste management platform; Container Management Module: Used to manage medical waste containers, summarize and organize each storage and transfer record, and issue processing instructions when preset conditions are met; Transfer module: Used to record the entire process of collection personnel transferring medical waste from medical waste containers in various departments to the hospital's temporary storage center; Storage module: Used to monitor and record each storage process when medical personnel store medical waste into the medical waste container; Temporary storage center module: Classifies all medical waste and manages the waste bags in the temporary storage center by zone according to the classification results; Early warning module: processes various early warnings issued by other modules; Abnormality management module: record the abnormal behavior of the collection personnel and medical personnel.

[0005] Further, the specific operation of the container arrangement module is: Based on the type of department, the type of medical waste corresponding to the department is obtained, the types of medical waste corresponding to each department are further classified, medical waste of different categories is allocated to different medical waste containers for storage, and each medical waste container of the department is uniquely numbered., using an RFID reader to store the type of medical waste stored in each medical waste container, the name of the department and the number of the medical waste container in the RFID tag, and pasting the FRID tag on the surface of the medical waste container of the corresponding department.

[0006] Further, the specific operation of the personnel registration module is: Medical personnel registration information includes: medical personnel department, name, age and contact information; collection personnel registration information includes: collection personnel name, age and contact information, and the division of collection departments for each collection personnel, different collection personnel corresponding to different department medical waste collection; management personnel registration information includes: management personnel position, age, name and contact information.

[0007] Further, the specific steps of the container management module are: Grouping by the number of medical waste containers forms a first-level page, which also contains the department to which the medical waste container belongs, the type of medical waste allowed to be put, and the location. The type of medical waste allowed to be put is the type of medical waste allocated to each medical waste container by the container arrangement module; the storage record and the transfer record are located in the second-level page; For each storage record, first identify the number of the medical waste container, divide the storage record into the corresponding medical waste container according to the number, classify by the type of medical waste, and count the quantity of each type of medical waste and the earliest storage time of each type of medical waste; based on the difference in the type of medical waste, a preset container storage time is set, the current time is subtracted from the earliest storage time of each type of medical waste, and the storage time of each type of medical waste is obtained; Extract the weight of each type of medical waste from the preset database, multiply the weight of each type of medical waste by the corresponding quantity and sum, and the sum is taken as the waste weight of the corresponding medical waste container. A waste weight threshold is preset. extracting the earliest storage time of each medical waste type in the medical waste container, subtracting the earliest storage time from the current time to obtain the residence time of each medical waste type; presetting a residence time threshold of each medical waste type, dividing the residence time of each medical waste type by the corresponding residence time threshold and summing up to obtain a residence comprehensive index of the garbage bag; presetting a severity score for each type of medical waste, obtaining the corresponding quantity of each type of medical waste in the medical waste container, dividing the quantity of each type of medical waste by the total quantity of medical waste in the garbage bag to obtain the proportion of each type of medical waste, denoted as quantity ratio, multiplying the quantity ratio of each type of medical waste by the corresponding severity score and summing up to obtain a severity indication value of the medical waste container; presetting weight influence factors of the residence comprehensive index and the severity indication value, multiplying the normalized residence comprehensive index and the normalized severity indication value by the corresponding weight influence factors and summing up to obtain a processing value of each medical waste container, and presetting a processing value threshold; When the medical waste container meets the preset condition, a processing instruction is sent to the mobile terminal of the collection personnel, and the position and number of the medical waste container are synchronously sent to the mobile terminal of the collection personnel. The preset condition refers to: the storage time of any type of medical waste is greater than the corresponding container storage time, or the waste weight is greater than the waste weight threshold, or the processing value is greater than the processing value threshold. After receiving the processing instruction, the collection personnel goes to the position of the medical waste container to collect the medical waste; For each transfer record, first, the transfer record is divided into the corresponding medical waste container according to the medical waste container number; based on the distance of each waste container from the hospital medical waste temporary storage center, a transfer time is preset; the time when the medical waste leaves the container is extracted from the transfer record, and the time is counted from the time when the medical waste leaves the container. If the counting exceeds the transfer time, a transfer timeout warning is issued.

[0008] Further, the specific steps of the storage module for detecting and recording each storage process are: When the medical staff prepares to store the medical waste into the medical waste container, first, the hand-held RFID reader is logged in, and then the RFID reader scans the RFID tag of the medical waste container, the RFID reader receives the information returned by the RFID tag and sends it to the control center, the control center extracts the department name and the medical waste container number in the returned information, and compares it with the department to which the medical staff currently logged in the hand-held RFID reader belongs, if the names are inconsistent, the hand-held RFID reader will be sent a storage error warning; if the names are consistent, the medical staff inputs the type and quantity of the medical waste stored this time in the hand-held RFID reader, after the input is completed, the type of the medical waste stored this time is sent to the control center, the control center obtains the allowed medical waste types according to the medical waste container number, and compares the types of the medical waste stored this time with the allowed medical waste types, if the comparison fails, the hand-held RFID reader will be sent a type mismatch warning, and the medical waste type that fails to match will be marked red; If the comparison is successful, the type and quantity of the medical waste stored this time, the storage time, the medical staff registration information currently logged in the hand-held RFID reader, and the current medical waste container number are integrated to form a storage record, and sent to the container management module.

[0009] Further, the specific steps of the transfer module are: When the collection personnel collect the medical waste, first, the hand-held RFID reader is logged in, after logging in, the RFID tag of the medical waste container is read and written by the hand-held RFID reader, and the content in the RFID tag is sent to the control center, the control center extracts the department name in the RFID tag, and compares it with the collection department of the collection personnel currently logged in the hand-held RFID reader, if the result is inconsistent, the hand-held RFID reader will be sent a collection error warning; If the result is consistent, the collection personnel take out the garbage bag in the medical waste container and seal it, get the types of medical waste in the current medical waste container, the quantity of each type of medical waste, and the waste weight from the container management module, and request the control center to generate a unique string, then use the hand-held RFID reader to write the types of medical waste in the current medical waste container, the quantity of each type of medical waste, the waste weight, and the string into a new RFID tag, and paste the new RFID tag on the surface of the garbage bag; at the same time, the time when the medical waste leaves the container, the medical waste container number, the name and contact information of the collection personnel, and the string are integrated to form a transfer record, and sent to the container management module; Subsequently, collection personnel transported the garbage bags to the hospital's temporary storage center along a pre-set route. At the entrance of the temporary storage center, fixed RFID readers and weighing devices were installed. Collection personnel first placed the garbage bags on the weighing device, which then transmitted the weight of the garbage bags to the fixed RFID readers. Simultaneously, the fixed RFID readers read the RFID tags on the surface of the garbage bags and sent the RFID tag information and the weight of the garbage bags to the control center. The control center extracted a string from the tag information and located the corresponding container in the container management module based on the string. The system retrieves the waste weight from the transfer record, calculates the difference between the waste weight and the weight of the garbage bag, and takes the absolute value as the difference weight. A preset difference weight threshold is set. If the difference weight exceeds the threshold, a transfer error warning is issued. Otherwise, the garbage bag is stored in the corresponding temporary storage area, and the storage time is obtained. If the container management module does not issue a transfer timeout warning before storing the garbage bag in the temporary storage area, the timer is stopped and the storage time is written to the corresponding transfer record. If a timeout warning has been issued, only the storage time is written to the corresponding transfer record.

[0010] Furthermore, the specific steps of the temporary storage center module are as follows: Medical waste is categorized into five types: infectious, pathological, traumatic, pharmaceutical, and chemical, and the specific type of medical waste in the garbage bags is matched accordingly. The temporary storage center is divided into five areas, each corresponding to a type of medical waste, and the garbage bags are stored in the corresponding area according to their type.

[0011] Furthermore, the specific steps for the early warning module to process various early warnings are as follows: Transfer Timeout Warning: Obtain the transfer route of medical waste containers that trigger the warning, divide the transfer route into monitoring areas to form sub-routes, locate the corresponding collection personnel in the monitoring video, calculate the residence time of the collection personnel in each sub-routes, and preset the standard residence time value for each sub-routes based on the length of each sub-routes; subtract the corresponding standard residence time value from the residence time of the collection personnel in each sub-routes to obtain the timeout value for each sub-routes; If no collection personnel are detected in the monitoring video of a certain transfer sub-route, it is determined that the collection personnel did not transfer according to the preset route. The control center sends a situation report to the collection personnel's mobile terminal. After the collection personnel completes the report, they send it back to the control center. The control center records the situation report under the corresponding collection personnel in the anomaly management module. At the same time, the control center sends the situation report and the collection personnel's registration information to the mobile terminal of the management personnel for comprehensive decision-making. If a collection person is detected in all the transfer sub-routes, then extract the sub-routes in each sub-routes whose dwell time is greater than the standard dwell time value, and record the extracted sub-routes below the corresponding collection person in the anomaly management module; Collection error alert: Acquire video of the area where the medical waste container triggers the alert, acquire monitoring video of the preset time interval according to the alert time, locate the collection personnel through facial recognition technology, and generate a collection error record under the corresponding collection personnel in the anomaly management module; Transfer error warning: The control center sends a transfer error warning to the mobile terminal of the management personnel. The management personnel retrieve and analyze the video of the entire process of the corresponding medical waste container being first put into the garbage bag and transferred to the hospital's temporary storage center, and determine the specific handling plan. Storage Error Alert: Obtain video footage from the medical waste container that triggered the alert, acquire surveillance video within a preset time interval based on the alert time, locate the medical personnel, and use multimodal fusion technology to determine whether the medical personnel disposed of medical waste into the medical waste container. If no waste was disposed of, generate a container classification error record under the corresponding medical personnel in the anomaly management module; if waste was disposed of, generate a storage error record under the corresponding medical personnel in the anomaly management module. Mismatch Alert: Acquire video footage of the medical waste container that triggered the alert, and obtain surveillance video within a preset time interval based on the alert time to locate the medical personnel; acquire a frame image of medical waste that has not been disposed of in the medical waste container, and use an object detection algorithm to determine the type of medical waste that the medical personnel are preparing to dispose of, as the initial disposal type; acquire a frame image of medical waste that has not been disposed of in the medical waste container after disposal, and use an object detection algorithm to determine the type of medical waste that has not been disposed of, as the final disposal type; The system compares the end-of-life category with the medical waste categories marked in red using the handheld RFID reader. If the end-of-life category is the same as the medical waste category marked in red, a classification error record is generated under the medical personnel corresponding to the anomaly management module. If the end-of-life category includes all medical waste categories marked in red, and the number of end-of-life categories is greater than the number of medical waste categories marked in red, a disposal incomplete record is generated under the medical personnel corresponding to the anomaly management module. If the medical waste categories marked in red include all end-of-life categories, and the number of end-of-life categories is less than the number of medical waste categories marked in red, a storage category error record is generated under the medical personnel corresponding to the anomaly management module.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention assigns RFID tags to medical waste containers in each department. The tags store the department to which the medical waste container belongs and the types of medical waste that are permitted to be disposed of. When a medical staff member puts medical waste into the medical waste container, the system first compares the departments. If they do not match, an error warning is issued. Then, it compares the types of medical waste. If they do not match, a type mismatch warning is issued. The warning module analyzes the warnings to ensure the proper disposal of medical waste. This invention categorizes and organizes the storage records of medical waste containers to obtain the earliest storage time of various types of medical waste, the waste weight of the medical waste containers, and the treatment value. By issuing treatment instructions through threshold comparison, it can effectively avoid medical waste from being stored in containers for too long, reduce the risk of infection and contamination, and prevent medical waste containers from overflowing. This invention monitors the entire process of medical waste transfer from medical waste containers to a temporary storage center using a transfer module. When the waste bags are packed in the medical waste containers, the system matches the collection personnel's department with the department to which the medical waste container belongs. If the match fails, a collection error warning is issued. At the entrance of the temporary storage center, the difference between the waste weight and the actual weight of the waste bag is obtained. A threshold comparison is used to determine if there is a problem with the weight of the waste bag, and a transfer error warning is issued. The warning module handles both collection and transfer error warnings, improving the accuracy and efficiency of medical waste transfer management and reducing management risks.

[0014] Several embodiments of this application will now be described in more detail with reference to the accompanying drawings to enable those skilled in the art to implement this application. This application may be embodied in many different forms and for various purposes and should not be limited to the embodiments set forth herein. These embodiments are provided to make this application thorough and complete, and to fully convey the scope of this application to those skilled in the art. The embodiments described do not limit this application.

[0015] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It will be further understood that terms such as those defined in commonly used dictionaries shall be interpreted as having a meaning consistent with their meaning in the relevant field and / or the context of this specification, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0016] Please see Figure 1 As shown, a medical waste management platform based on RFID technology includes: a container deployment module, a personnel registration module, a container management module, a storage module, a transfer module, a temporary storage center module, an early warning module, and an anomaly management module; Container deployment module: Used to deploy containers for storing medical waste in various departments of the hospital; Based on the type of department, obtain the corresponding medical waste types of the department, perform secondary classification of the medical waste types of each department, assign different types of medical waste to different medical waste containers for storage, and assign a unique number to each department's medical waste container. Use an RFID reader to store the type of medical waste stored in each medical waste container, the department name, and the medical waste container number into an RFID tag, and affix the RFID tag to the surface of the corresponding department's medical waste container. By assigning a unique number to each container and storing key information in an RFID tag that is affixed to the container surface, each container and the waste inside it are uniquely identified. In subsequent storage and transfer processes, the tag information can be read to accurately trace the source department and category of the waste, making it easier to quickly locate the root cause when problems occur. Personnel registration module: Used for hospital medical personnel, collection personnel, and management personnel to register on the medical waste management platform; The registration information for medical personnel includes: the department to which the medical personnel belong, their name, age, and contact information; the registration information for collection personnel includes: the name, age, and contact information of the collection personnel, and the departments to which each collection personnel collects medical waste are assigned, with different collection personnel corresponding to the collection of medical waste from different departments; the registration information for management personnel includes: the position, age, name, and contact information of the management personnel.

[0017] Container Management Module: Used to manage medical waste containers, summarize and organize each storage and transfer record, and issue processing instructions when preset conditions are met; The medical waste containers are grouped by their numbers to form a first-level page. The first-level page also includes the department to which the medical waste container belongs, the types of medical waste that can be disposed of, and its location. The types of medical waste that can be disposed of are the types of medical waste assigned to each medical waste container by the container deployment module. The storage records and transfer records are located on the second-level page. For each storage record, first identify the number of the medical waste container, and then classify the storage record under the corresponding medical waste container according to the number. Classify the medical waste by type, and count the quantity of each type of medical waste and the earliest storage time of each type of medical waste. Based on the different types of medical waste, a container storage time is preset. Subtract the earliest storage time of each type of medical waste from the current time to obtain the storage time of each type of medical waste. Extract the weight of various types of medical waste from the preset database, multiply the weight of each type of medical waste by the corresponding quantity and then sum them up. The sum is used as the waste weight of the corresponding medical waste container. A preset waste weight threshold is set. Extract the earliest entry time of each type of medical waste in the medical waste container, and use the current time minus the earliest entry time as the retention time of each type of medical waste; preset the retention time threshold for each type of medical waste, divide the retention time of each type of medical waste by the corresponding retention time threshold and then sum them up, and use the result as the comprehensive retention index of the garbage bag. Based on the infection risk and hazardous substance content of various types of medical waste, a severity score is preset for each type of medical waste. The higher the infection risk and the higher the hazardous substance content of a type of medical waste, the higher the corresponding severity score. The quantity of each type of medical waste in the medical waste container is obtained. The quantity of each type of medical waste is divided by the total quantity of medical waste in the garbage bag to obtain the proportion of each type of medical waste, which is recorded as the quantity ratio. The quantity ratio of each type of medical waste is multiplied by the corresponding severity score and then summed. The final result is used as the severity indicator value of the medical waste container. The weighting factors of the retention comprehensive index and severity indicator value are preset. After normalizing the retention comprehensive index and severity indicator value, they are multiplied by the corresponding weighting factors and then summed to obtain the treatment value of each medical waste container. The treatment value threshold is preset. When the medical waste container meets the preset conditions, a processing instruction is sent to the mobile terminal of the collector, and the location and number of the medical waste container are sent to the mobile terminal of the collector simultaneously. The preset conditions refer to: the storage time of any type of medical waste is greater than the corresponding container storage time, or the waste weight is greater than the waste weight threshold, or the processing value is greater than the processing value threshold; after receiving the processing instruction, the collector goes to the location of the medical waste container to collect the medical waste. By setting storage time, calculating waste weight and treatment value, and comparing thresholds, the system can promptly issue treatment instructions to collection personnel when medical waste containers meet preset conditions. This can effectively avoid the risk of infection and pollution caused by long-term storage of waste in containers, prevent container overflow, and ensure the safety of the hospital environment. For each transfer record, the transfer record is first assigned to the corresponding medical waste container according to the medical waste container number; a transfer time is preset based on the distance of each waste container from the hospital's medical waste temporary storage center; the time when the medical waste leaves the container is extracted from the transfer record, and the timer starts from the time when the medical waste leaves the container. If the timer exceeds the transfer time, a transfer timeout warning is issued. Based on the preset transfer time between the container and the temporary storage center, the transfer process is timed and monitored. If the transfer time is exceeded, an overdue warning is issued to ensure that the collection personnel transfer the waste to the temporary storage center in a timely manner, thus ensuring the timeliness of medical waste transfer and avoiding the impact on the overall processing flow due to untimely transfer.

[0018] Storage module: Used to monitor and record each storage process when medical personnel store medical waste into the medical waste container; When medical personnel are preparing to store medical waste in a medical waste container, they first log in using a handheld RFID reader. Then, they use the RFID reader to scan the RFID tag on the medical waste container. The RFID reader receives the information returned by the RFID tag and sends it to the control center. The control center extracts the department name and medical waste container number from the returned information and compares it with the department of the medical personnel currently logged in to the handheld RFID reader. If the names do not match, an error warning is sent to the handheld RFID reader via the wireless network. Before medical personnel deposit waste, the system compares their department with the department of the container. If they do not match, an error warning is issued. This measure can effectively prevent medical personnel from depositing waste into containers of the wrong department, avoid deviations in subsequent processing due to departmental confusion, and maintain the departmental correspondence order of waste management. If the names match, the medical personnel enter the type and quantity of medical waste to be stored in the handheld RFID reader. After entering the information, the type of medical waste to be stored is first sent to the control center via the wireless network. The control center obtains the permitted types of medical waste based on the medical waste container number and compares the type of medical waste to be stored with the permitted types. If the comparison fails, that is, the type of medical waste entered by the medical personnel does not match the permitted types, the control center sends a type mismatch warning to the handheld RFID reader via the wireless network and marks the medical waste type that failed to match in red. The control center compares the types of waste stored with the types allowed to be disposed of in the containers. If there is a mismatch, an alert is issued and the incorrect type is marked in red. This mechanism ensures that medical waste is disposed of in accordance with regulations, reduces the processing risks caused by mixing different types of waste, and improves the accuracy of waste classification. If the comparison is successful, the type and quantity of medical waste deposited this time, the deposit time, the registration information of the medical personnel currently logged into the handheld RFID reader, and the number of the current medical waste container will be integrated to form a deposit record, which will be sent to the container management module via wireless network. The deposit time is the time displayed on the handheld RFID reader after the medical personnel have entered the type and quantity of medical waste to be deposited this time. These records cover the type and quantity of waste, storage time, personnel information, and container number, providing detailed evidence for the full traceability of medical waste from its source to subsequent treatment, facilitating the rapid identification of responsibility and links when problems occur.

[0019] Transfer module: Used to record the entire process of collection personnel transferring medical waste from medical waste containers in various departments to the hospital's temporary storage center; When collecting medical waste, the collectors first log in to a handheld RFID reader. After logging in, they use the handheld RFID reader to read the RFID tag on the medical waste container and send the contents of the RFID tag to the control center via a wireless network. The control center extracts the department name from the RFID tag and compares it with the department of the collector currently logged in to the handheld RFID reader. If the results are inconsistent, a collection error warning is sent to the handheld RFID reader. If the results match, the collection personnel remove and seal the waste bags from the medical waste containers. Using a wireless network, they obtain the types of medical waste, the quantity of each type, and the weight from the container management module. They then request the control center to generate a unique identifier string that corresponds to the currently collected waste bag. Subsequently, using a handheld RFID reader, they write the types of medical waste, the quantity of each type, the weight, and the string into a new RFID tag and affix it to the surface of the waste bag. Simultaneously, they integrate the time the medical waste left the container, the medical waste container number, the collector's name, contact information, and the string to form a transfer record, which is then sent to the container management module via a wireless network. A unique identifier string is generated for each waste bag and relevant information is recorded. Key data during the transfer process is integrated into a record and sent to the container management module. This makes the flow of medical waste from departmental containers to the temporary storage center traceable, which facilitates subsequent query and management and allows for quick identification of the link and responsible person in case of problems. Subsequently, collection personnel transported the garbage bags to the hospital's temporary storage center along a pre-set route. At the entrance of the temporary storage center, fixed RFID readers and weighing devices were installed. The weighing device and the fixed RFID reader were connected via Wi-Fi. Collection personnel first placed the garbage bags on the weighing device, which then transmitted the weight of the garbage bags to the fixed RFID reader via the wireless network. Simultaneously, the fixed RFID reader read the RFID tags on the surface of the garbage bags and transmitted the RFID tag information and the weight of the garbage bags to the control center via the wireless network. The control center extracted the string from the tag information. The system locates the corresponding transfer record in the container management module based on the string, extracts the waste weight from the transfer record, calculates the difference between the waste weight and the weight of the garbage bag, and takes the absolute value as the difference weight. A preset difference weight threshold is set. If the difference weight is greater than the difference weight threshold, a transfer error warning is issued. Otherwise, the garbage bag is stored in the corresponding temporary storage area, and the storage time is obtained. If the container management module does not issue a transfer timeout warning before the garbage bag is stored in the temporary storage area, the timer is stopped and the storage time is written to the corresponding transfer record. If a timeout warning has been issued, only the storage time is written to the corresponding transfer record. At the entrance of the temporary storage center, the actual weight of the garbage bag is compared with the recorded weight. If the difference is too large, an error warning is issued to ensure the accuracy of the waste weight. At the same time, combined with the transfer timeout warning mechanism, the transfer time is monitored to ensure that medical waste is stored in the temporary storage center in a timely and accurate manner, thereby improving the quality of transfer management.

[0020] Temporary storage center module: Classifies all medical waste and manages the waste bags in the temporary storage center by zone according to the classification results; Medical waste is categorized into five types: infectious, pathological, traumatic, pharmaceutical, and chemical, and the specific type of medical waste in the garbage bags is matched accordingly. The temporary storage center is divided into five areas, each corresponding to a type of medical waste, and the garbage bags are stored in the corresponding area according to their type.

[0021] Early warning module: processes various early warnings issued by other modules; Transfer Timeout Warning: Obtain the transfer routes of medical waste containers that trigger the warning, divide the transfer routes into monitoring areas to form sub-routes, use facial recognition technology to locate the corresponding collection personnel in the monitoring video, calculate the time the collection personnel stay in each transfer sub-route, and preset the standard value of the stay time for each sub-route based on the length of each transfer sub-route; subtract the corresponding standard value of the stay time from the time the collection personnel stay in each sub-route to obtain the timeout value for each sub-route; If no collection personnel are detected in the monitoring video of a certain transfer sub-route, it is determined that the collection personnel did not transfer according to the preset route. The control center sends a situation report to the collection personnel's mobile terminal. After the collection personnel completes the report, they send it back to the control center. The control center records the situation report under the corresponding collection personnel in the anomaly management module. The content filled in the control report includes the actual route of this transfer and the reason for not following the preset route. At the same time, the control center sends the situation report and the collection personnel's registration information to the mobile terminal of the management personnel for comprehensive decision-making. If a collection person is detected in all the transfer sub-routes, then extract the sub-routes in each sub-routes whose dwell time is greater than the standard dwell time value, and record the extracted sub-routes below the corresponding collection person in the anomaly management module; By dividing the transfer routes and calculating the time that collection personnel spend on each transfer sub-route, problems such as transfer timeouts and route violations can be detected in a timely manner. When problems occur, information is collected through situation reports and decisions are made by management personnel. At the same time, anomalies are recorded to ensure that the transfer is carried out efficiently according to plan and to improve the overall circulation efficiency. Collection error alert: Acquire video of the area where the medical waste container triggers the alert, acquire monitoring video of the preset time interval according to the alert time, locate the collection personnel through facial recognition technology, and generate a collection error record under the corresponding collection personnel in the anomaly management module; Transfer error warning: The control center sends a transfer error warning to the mobile terminal of the management personnel. The management personnel retrieve and analyze the video of the entire process of the corresponding medical waste container being first put into the garbage bag and transferred to the hospital's temporary storage center, and determine the specific handling plan. Storage Error Alert: Acquire video footage of the medical waste container that triggered the alert, obtain surveillance video within a preset time range based on the alert time, locate the medical personnel using facial recognition technology, and determine whether the medical personnel disposed of medical waste into the medical waste container using multimodal fusion technology. If no waste was disposed of, generate a container classification error record under the corresponding medical personnel in the anomaly management module; if waste was disposed of, generate a storage error record under the corresponding medical personnel in the anomaly management module. Mismatch Alert: Acquire video footage of the medical waste container that triggered the alert, acquire surveillance video within a preset time interval based on the alert time, and locate medical personnel using facial recognition technology; acquire a frame image of medical waste that has not been disposed of in the medical waste container, and use object detection algorithms to determine the type of medical waste that the medical personnel are preparing to dispose of, as the initial disposal type; acquire a frame image of medical waste that has not been disposed of in the medical waste container after disposal, and use object detection algorithms to determine the type of medical waste that has not been disposed of, as the final disposal type; The system compares the end-of-life category with the medical waste categories marked in red using the handheld RFID reader. If the end-of-life category is the same as the medical waste category marked in red, a classification error record is generated under the medical personnel corresponding to the anomaly management module. If the end-of-life category includes all medical waste categories marked in red, and the number of end-of-life categories is greater than the number of medical waste categories marked in red, a disposal incomplete record is generated under the medical personnel corresponding to the anomaly management module. If the medical waste categories marked in red include all end-of-life categories, and the number of end-of-life categories is less than the number of medical waste categories marked in red, a storage category error record is generated under the medical personnel corresponding to the anomaly management module.

[0022] Anomaly Management Module: Records abnormal behaviors of data collection personnel and medical personnel.

[0023] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention.

4. A medical waste management platform based on RFID technology according to claim 1, characterized in that, The specific steps of the container management module are as follows: The medical waste containers are grouped by their numbers to form a first-level page. The first-level page also includes the department to which the medical waste container belongs, the types of medical waste that can be disposed of, and its location. The types of medical waste that can be disposed of are the types of medical waste assigned to each medical waste container by the container deployment module. The storage records and transfer records are located on the second-level page. For each storage record, first identify the number of the medical waste container, and then classify the storage record under the corresponding medical waste container according to the number. Classify the medical waste by type, and count the quantity of each type of medical waste and the earliest storage time of each type of medical waste. Based on the different types of medical waste, a container storage time is preset. Subtract the earliest storage time of each type of medical waste from the current time to obtain the storage time of each type of medical waste. Extract the weight of various types of medical waste from the preset database, multiply the weight of each type of medical waste by the corresponding quantity and then sum them up. The sum is used as the waste weight of the corresponding medical waste container. A preset waste weight threshold is set. Extract the earliest entry time of each type of medical waste in the medical waste container, and use the current time minus the earliest entry time as the retention time of each type of medical waste; preset the retention time threshold for each type of medical waste, divide the retention time of each type of medical waste by the corresponding retention time threshold and then sum them up, and use the result as the comprehensive retention index of the garbage bag. A severity score is preset for each type of medical waste. The quantity of each type of medical waste in the medical waste container is obtained. The proportion of each type of medical waste is obtained by dividing the quantity of each type of medical waste by the total quantity of medical waste in the garbage bag. This proportion is recorded as the quantity ratio. The quantity ratio of each type of medical waste is multiplied by the corresponding severity score and then summed. The final result is used as the severity indicator value of the medical waste container. The weighting factors of the retention comprehensive index and severity indicator value are preset. After normalizing the retention comprehensive index and severity indicator value, they are multiplied by the corresponding weighting factors and then summed to obtain the treatment value of each medical waste container. The treatment value threshold is preset. When the medical waste container meets the preset conditions, a processing instruction is sent to the mobile terminal of the collector, and the location and number of the medical waste container are sent to the mobile terminal of the collector simultaneously. The preset conditions refer to: the storage time of any type of medical waste is greater than the corresponding container storage time, or the waste weight is greater than the waste weight threshold, or the processing value is greater than the processing value threshold; after receiving the processing instruction, the collector goes to the location of the medical waste container to collect the medical waste. For each transfer record, the transfer record is first assigned to the corresponding medical waste container based on the medical waste container number; a transfer time is preset based on the distance of each waste container from the hospital's medical waste temporary storage center; the time when the medical waste leaves the container is extracted from the transfer record, and the timer starts from the time when the medical waste leaves the container. If the timer exceeds the transfer time, a transfer timeout warning is issued.

5. A medical waste management platform based on RFID technology according to claim 1, characterized in that, The specific steps for the storage module to detect and record each storage process are as follows: When medical personnel are preparing to store medical waste in a medical waste container, they first register with a handheld RFID reader. Then, they use the RFID reader to scan the RFID tag on the medical waste container. The RFID reader receives the information returned by the RFID tag and sends it to the control center. The control center extracts the department name and medical waste container number from the returned information and compares it with the department of the medical personnel currently registered with the handheld RFID reader. If the names do not match, an error warning is issued to the handheld RFID reader. If the names match, medical personnel enter the type and quantity of medical waste to be stored in the handheld RFID reader. After entering the information, the type of medical waste to be stored is sent to the control center. The control center obtains the permitted types of medical waste based on the medical waste container number and compares the type of medical waste to be stored with the permitted types of medical waste. If the comparison fails, a type mismatch warning is sent to the handheld RFID reader, and the medical waste type that fails to match is marked in red. If the comparison is successful, the type and quantity of medical waste deposited, the deposit time, the registration information of the medical personnel currently logged into the handheld RFID reader, and the number of the current medical waste container will be integrated to form a deposit record and sent to the container management module.

6. A medical waste management platform based on RFID technology according to claim 1, characterized in that, The specific steps of the transfer module are as follows: When collecting medical waste, the collectors first register on a handheld RFID reader. After registering, they use the handheld RFID reader to read the RFID tag on the medical waste container and send the contents of the RFID tag to the control center. The control center extracts the department name from the RFID tag and compares it with the department of the collector currently registered on the handheld RFID reader. If the results are inconsistent, a collection error warning is sent to the handheld RFID reader. If the results match, the collection personnel remove and seal the waste bags from the medical waste container, obtain the type of medical waste, the quantity of each type of medical waste, and the weight of the waste from the container management module, and request the control center to generate a unique identifier string. Then, using a handheld RFID reader, they write the type of medical waste, the quantity of each type of medical waste, the weight of the waste, and the string into a new RFID tag and affix this new RFID tag to the surface of the waste bag. At the same time, they integrate the time when the medical waste left the container, the medical waste container number, the name and contact information of the collection personnel, and the string to form a transfer record and send it to the container management module. Subsequently, the collection personnel transported the garbage bags to the hospital's temporary storage center along a pre-set route. At the entrance of the hospital's temporary storage center, there were fixed RFID readers and weighing devices. The collection personnel first placed the garbage bags on the weighing device, and the weighing device sent the weight of the garbage bags to the fixed RFID readers. At the same time, the fixed RFID readers read the RFID tags on the surface of the garbage bags and sent the RFID tag information and the weight of the garbage bags to the control center. The control center extracted a string from the tag information, located the corresponding transfer record in the container management module based on the string, extracted the waste weight from the transfer record, and calculated the difference between it and the weight of the garbage bags. The absolute value of the difference was taken as the difference weight. A preset difference weight threshold was set. If the difference weight was greater than the difference weight threshold, a transfer error warning was issued. Conversely, the garbage bag is stored in the corresponding temporary storage area, and the storage time is obtained. If the container management module does not issue a transfer timeout warning before the garbage bag is stored in the temporary storage area, the timer is stopped and the storage time is written to the corresponding transfer record; if a timeout warning has been issued, only the storage time is written to the corresponding transfer record.

7. A medical waste management platform based on RFID technology according to claim 1, characterized in that, The specific steps of the temporary storage center module are as follows: Medical waste is categorized into five types: infectious, pathological, traumatic, pharmaceutical, and chemical, and the specific type of medical waste in the garbage bags is matched accordingly. The temporary storage center is divided into five areas, each corresponding to a type of medical waste, and the garbage bags are stored in the corresponding area according to their type.

8. A medical waste management platform based on RFID technology according to claim 1, characterized in that, The specific steps for the early warning module to process various early warnings are as follows: Transfer Timeout Warning: Obtain the transfer route of medical waste containers that trigger the warning, divide the transfer route into monitoring areas to form sub-routes, locate the corresponding collection personnel in the monitoring video, calculate the residence time of the collection personnel in each sub-routes, and preset the standard residence time value for each sub-routes based on the length of each sub-routes; subtract the corresponding standard residence time value from the residence time of the collection personnel in each sub-routes to obtain the timeout value for each sub-routes; If no collection personnel are detected in the monitoring video of a certain transfer sub-route, it is determined that the collection personnel did not transfer according to the preset route. The control center sends a situation report to the collection personnel's mobile terminal. After the collection personnel completes the report, they send it back to the control center. The control center records the situation report under the corresponding collection personnel in the anomaly management module. At the same time, the control center sends the situation report and the collection personnel's registration information to the mobile terminal of the management personnel for comprehensive decision-making. If a collection person is detected in all the transfer sub-routes, then extract the sub-routes in each sub-routes whose dwell time is greater than the standard dwell time value, and record the extracted sub-routes below the corresponding collection person in the anomaly management module; Collection error alert: Acquire video of the area where the medical waste container triggers the alert, acquire monitoring video of the preset time interval according to the alert time, locate the collection personnel through facial recognition technology, and generate a collection error record under the corresponding collection personnel in the anomaly management module; Transfer error warning: The control center sends a transfer error warning to the mobile terminal of the management personnel. The management personnel retrieve and analyze the video of the entire process of the corresponding medical waste container being first put into the garbage bag and transferred to the hospital's temporary storage center, and determine the specific handling plan. Storage Error Alert: Obtain video footage from the medical waste container that triggered the alert, acquire surveillance video within a preset time interval based on the alert time, locate the medical personnel, and use multimodal fusion technology to determine whether the medical personnel disposed of medical waste into the medical waste container. If no waste was disposed of, generate a container classification error record under the corresponding medical personnel in the anomaly management module; if waste was disposed of, generate a storage error record under the corresponding medical personnel in the anomaly management module. Mismatch Alert: Acquire video footage of the medical waste container that triggered the alert, and obtain surveillance video within a preset time interval based on the alert time to locate the medical personnel; acquire a frame image of medical waste that has not been disposed of in the medical waste container, and use an object detection algorithm to determine the type of medical waste that the medical personnel are preparing to dispose of, as the initial disposal type; acquire a frame image of medical waste that has not been disposed of in the medical waste container after disposal, and use an object detection algorithm to determine the type of medical waste that has not been disposed of, as the final disposal type; The system compares the end-of-life category with the medical waste categories marked in red using the handheld RFID reader. If the end-of-life category is the same as the medical waste category marked in red, a classification error record is generated under the medical personnel corresponding to the anomaly management module. If the end-of-life category includes all medical waste categories marked in red, and the number of end-of-life categories is greater than the number of medical waste categories marked in red, a disposal incomplete record is generated under the medical personnel corresponding to the anomaly management module. If the medical waste categories marked in red include all end-of-life categories, and the number of end-of-life categories is less than the number of medical waste categories marked in red, a storage category error record is generated under the medical personnel corresponding to the anomaly management module.
