Description

Intelligent medicine unitized transportation method and system based on Internet of things
Technical Field
The invention relates to the technical field of Internet of things, in particular to an intelligent medicine unitized transportation method and system based on the Internet of things.
Background
The medicine is used as a special commodity, a lot of problems need to be noticed in the transportation process, the selection of a loading container of the medicine, the transportation traceability and the real-time visibility of the state of the medicine in the transportation process need to be considered, and the temperature of a bearing container needs to be monitored for some special medicines such as Chinese herbal medicine products containing volatile oil, so that the influence of temperature change on the medicine effect is prevented. In recent years, the infrastructure of a medicine supply chain is gradually improved, particularly, two-ticket system is implemented in 2018 countries, the chain of the medicine supply chain is further shortened, medicine production, medicine circulation and terminal combination on the chain nodes are tighter, part of traditional circulation distribution enterprises are transformed like supply chain service providers, the aggregation effect of an industrial park is more obvious, the medicine distribution efficiency is greatly improved, the medical service level is improved, the flattening trend of the supply chain is remarkable, and decentralization is achieved.
The selection of drug loading containers is closely related to the number of batches and deliveries of drugs per delivery. In the transportation process of medicines, the medicine loading, unloading and carrying are intelligentized and widely applied to various medicine supply chains. However, specifications and packages of various medicines are inconsistent, standardized containers are lacked, the utilization rate of transportation space is low, so that batches of medicine transportation in the same batch are increased, the transportation efficiency is reduced, the temperature storage requirements of some special medicines cannot be met by the containers for loading the medicines, and the medicine effect of the medicines cannot be well guaranteed. Various medicine transport containers appear in the market at present, the utilization degree of the storage space of the containers is limited, the temperature environment required by medicine storage cannot be well guaranteed, and the medicine transport efficiency is difficult to further improve.
The source and flow of the drug is critical to the timely delivery of the correct drug to its destination, and thus traceability of drug delivery has become a critical part of drug delivery. Different medicines come from different production places, in order to know medicine transportation information in real time, the transportation process of the medicines needs to be traced, the tracing of the current medicine transportation process usually adopts an RFID technology, however, common medicine transportation tracing equipment on the market is usually accurate to a certain batch, rather than a certain unit, even a certain medicine, the tracing information of the medicines is fuzzy, and the error probability is increased.
The reform of the medicine supply chain promotes the development of the medicine supply chain towards flattening and decentralization, the supply chain is further shortened, and the medicine production, the medicine circulation and the terminal combination on the chain node are tighter. The method confirms that the two-ticket system is implemented on the spot, can greatly improve the drug transportation efficiency, improves the medical service level, and is beneficial to reducing the cost and sharing the resources of the medical information. However, in the current market, few medicine supply chains can confirm the implementation situation of two tickets, the cost reduction situation of medicine transportation is limited, and the transportation efficiency is difficult to go to the first floor.
The currently popular drug loading containers on the market have a small capacity and cannot dynamically adjust the temperature in the container according to the characteristics of the drugs, thereby reducing the drug transportation efficiency and possibly even affecting the shelf life and efficacy of the drugs. Medicine intelligence letter sorting equipment in the market, the categorised arrangement of medicine all need manual operation, have increased the probability of making mistakes to it is inefficient.

wherein:qdescribed is the average latency, L, of a standard cell in a queueqThe average number of standard cells waiting in the queue is described, and δ is the arrival rate of the standard cell. The system will prioritize the standard cells into a queue of shorter average wait times, the standard cells being transported along the conveyor in the queue, the RFID tag readers of the robotic arms on the conveyor identifying the RFID tags of the standard cells, and loading the standard cells into the intelligent transport unit. The RFID tag reader in the intelligent transportation unit will again identify the RFID tag of the standard unit to ensure that the loading is error-free. And the intelligent transportation unit sends the vehicle out of the cross reloading system after all the standard units are loaded.
In the embodiment of the invention, the intelligent sorting line with the tracing label code is provided for solving the problem of fuzzy tracing information in the drug transportation process, and the intelligent sorting line is incorporated into the cross reloading system. The method comprises the steps that corresponding label codes are attached to packages from a production place, the label codes record the types and specifications of medicines and the sources and the flow directions of the medicines, after the medicines enter an intelligent sorting line, machines on the sorting line scan the label codes of the medicines, and then the medicines are placed into each standard unit according to information on the label codes.
The background of the intelligent sorting line uploads the information on the label codes to the cloud and updates the flow direction information of the medicines, and the information of the standard units and the information of the medicines are correlated. The standard cells are then loaded into the intelligent pharmaceutical pig by a robotic arm. Overtime standard units can enter a temporary storage area to be temporarily stored for waiting for next batch of transportation, when the standard units enter the temporary storage area, sorting lines can identify the information of the standard units and update the logistics information of the standard units, and due to the fact that the medicine information is correlated with the standard unit information, the flow direction information of the medicines is correspondingly updated, and therefore traceability of the information of each medicine in each standard unit is achieved.
In the embodiment of the invention, aiming at the implementation situation problem of the two-ticket system, the intelligent cross reloading system based on the internet of things technology is provided. The label code of the medicine contains invoice information of the medicine, the cross reloading system can obtain the invoice information through scanning the label code, and strictly audit and file the information, and the transportation is carried out before the ticket replenishment is carried out on the condition that the short-supply medicine is confirmed to belong to two tickets. For the temporary drug supply source of bills, the cross reloading system can establish electronic files for real-time tracking, and complete bills are guaranteed.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
