1 Basic working principle of the system
The production and sales (or use) in the drug supply chain are likely not to be located in the same area adjacent to each other. There must be several links (production, warehousing, distribution, Transportation, etc.) to coordinate operations. In terms of logistics, there are usually air, sea, and land transportation for non-locally produced drugs. Taking sea transportation as an example, medicines are shipped to the destination port and then transported by land (train or truck) to reach the destination. Take air transportation as an example. Pharmaceutical cargo is loaded and transported to the destination airport, and then transported by other means of transportation to reach the destination. In response to these situations, the system adopts a “linkable” system structure, that is, each storage and each conversion and transportation is a “chain unit”. According to actual needs, multiple “chain units” can be linked to form a slave A complete system from the place where the goods are sent to the place where the goods arrive, tracking and managing the entire logistics link.
2 Basic functions of the management system
The mobile computer equipped with the system is equipped with the RFID drug logistics management system “chain unit system”, which includes various management functions such as label management, warehouse management, transportation management, and receiving management in the logistics link. In specific applications, each “chain unit” will be configured with corresponding functions according to its location in the logistics link (storage unit, transit unit, receiving unit). For example, the transfer unit cannot use the label management function, but can only use the receipt and delivery function. The following are the functions of a single “chain unit”:
2.1 Label issuance management function
The label issuance management subsystem in the drug logistics management system is mainly to complete the label issuance work before the drug goods are put into the warehouse. For the first chain unit, electronic labels (abbreviated as: labeling) must be affixed on the transport packaging of the goods in the warehouse before they can be truly included in the management of the system. The subsystem can perform operations such as label production and distribution, label and cargo information association based on background data.
2.2 Goods receiving and dispatching management function
The cargo receiving and dispatching management subsystem in the pharmaceutical logistics management system is mainly to complete the management of the entry and exit of pharmaceutical cargo. If it is the first “chain unit”, it will be processed according to the order list, if it is the middle “chain unit”, it will be processed according to the delivery list sent from the previous “chain unit”. This subsystem can perform procedures such as receiving, picking, and shipping. List the “Pick List” according to the “Order List” (or Delivery List), and transfer to the “Delivery List” after picking is completed. It can also convert the “Shipping List” into a “Shipping List” and send it to the unit responsible for transportation. The “chain unit” automatically updates the inventory list in the local database according to the incoming and outgoing goods information collected by the RFID reader, and transmits the processing information to the back-end data center.
If the RFID reader scans the goods that are not in the delivery list, the system will alarm by displaying the information and making a sound to prevent the goods that should not be out of the warehouse.
2.3 Warehousing goods inventory function
The inventory management subsystem of warehousing goods in the pharmaceutical logistics management system is mainly to complete the statistical inquiry of the receipt and delivery information in the system database and the verification of inventory information. If there is an inconsistency between the actual inventory information and the database inventory information in the inventory, The system will initiate an alarm and inform the management staff in the form of text and sound.
2.4 Cargo transportation monitoring function
The transportation monitoring management subsystem in the pharmaceutical logistics management system is mainly to complete the collection processing, monitoring the transportation process, and confirming the arrival of the goods. In order to improve transportation efficiency, the system will calculate a reasonable configuration plan for cargo collection and delivery vehicles to avoid false reports that may occur when third-party logistics is used, and to save logistics costs as much as possible.
In addition, the system can automatically generate a static diagram of temperature changes in the entire supply chain based on the collected temperature measurement record electronic tags. If the temperature exceeds the preset specified temperature, the temperature curve of the temperature static diagram will become Red to indicate alarm. The horizontal axis of the temperature static graph is time, and the vertical axis is temperature, so you can know exactly what changes in temperature occurred at what time, so that information can be traced back and responsibilities defined. If special medicines are to be transported, the on-board RPT Box system on the special vehicle can collect GPS information and RFID information of the goods carried in the carriage and the RFID information of the vehicle at the originally set data collection time interval, and transmit them To the back-end data center.
