Application of EVOC EPX products in the TCM code assignment system for IoT applications

The Internet of Things refers to the interconnection and interoperability of ubiquitous terminal devices and facilities, including sensors , mobile terminals, industrial systems, building control systems, home smart facilities, video surveillance systems, etc., and "external enablers", such as various assets with RFID , individuals and vehicles carrying wireless terminals, etc., through various wireless and wired long-distance and short-distance communication networks, large-scale application integration, and cloud computing-based SaaS operation models. In the intranet, private network, and Internet environment, appropriate information security protection mechanisms are adopted to provide safe, controllable and even personalized real-time online monitoring, positioning and tracing, alarm linkage, dispatching and command, plan management, remote control, security prevention, remote maintenance, online upgrades, statistical reports, decision support, leadership desktop and other management and service functions, so as to achieve the integration of "management, control and operation" of "everything" with "efficiency, energy saving, safety and environmental protection".

The electronic supervision code for drugs is a specific application of the concept of the Internet of Things. The electronic tag assigns a unique electronic supervision code to each smallest package of drugs, realizing "one code for one item" management, and collecting the dynamic information of drug production, circulation, use, etc. corresponding to the supervision code into the database in real time. Through a seamless network covering the whole country, a super-large database supporting tens of trillions of products of millions of enterprises and a professional customer service center, it provides information technology guarantee for the government to establish electronic archives for quality supervision from the source, track and trace the market, request certificates and invoices, implement incoming inspection and acceptance, establish electronic purchase and sales ledgers, and recall problematic drugs. Finally, an electronic supervision chain for the entire process of drugs from raw materials entering the factory, production and processing, factory sales to after-sales service has been established, and an electronic supervision chain for the entire process of drugs from planting and breeding, production and processing, circulation and sales to use has been established, providing an information technology platform for the establishment of a traceability and accountability system for drug quality and safety, and an electronic supervision network for drug quality covering the whole society has been established.

The drug supervision code data collection system can print labels on site or in advance during primary packaging. During secondary packaging, the drug supervision code of the primary packaging is scanned, and the system automatically counts according to the pre-set packaging specifications. When the number reaches the packaging specification, the system drives the barcode printer to print the secondary packaging code, and then packages and affixes the barcode. If there is a next-level packaging according to the packaging specification, the same packaging procedure is entered to perform a higher-level packaging operation. If the highest level of packaging specified in the packaging specification is reached, the packaging is prompted to be offline. In each layer of packaging, the upper-level packaging supervision code is automatically associated with the corresponding scanned lower-level supervision code. The packaging supervision codes of each layer of each largest package are associated as a whole through layer-by-layer association. The corresponding upper-level code or lower-level code can be queried in the system through any packaged supervision code.

The drug supervision code hardware system consists of a server, a printing PC , a flat labeling machine, an on-site industrial control computer, a drug supervision code scanner, a barcode printer, etc. In addition, the existing equipment needs to be modified according to the implementation of the system.

Based on the characteristics of the industry, the following requirements are put forward for the drug supervision code hardware system:

1. Diversified hardware peripherals: The drug supervision code assignment system consists of a variety of hardware devices, mainly including handheld, fixed, laser, barcode, label and other coding/scanning devices, all of which need to be connected to the coding industrial computer;

2. High stability and reliability: The system is used in the production line of a pharmaceutical factory, and general operators do not have professional computer maintenance capabilities. At the same time, the working status of the coding industrial computer directly affects the production process of the production line.

This product, which is professionally used in the drug supervision code assignment system, has several advantages:

1. EVOC's unique EPI bus and its interface use European connectors to replace the gold finger connection method, 360-degree contact, sealed and dustproof, solid structure, vibration resistance, and can withstand a certain gravity to ensure a stable and firm connection;

2. Excellent air intake and heat dissipation design, real-time monitoring of the whole machine temperature;

3. Rich expansion, fully satisfying the stable and convenient access of multiple coding/scanning devices such as handheld, fixed, laser, barcode, and label on-site control;

4. Support truly high-performance dual-gigabit networks, providing a good network environment for coding application/issuance.

In short, the EPI bus products developed by EVOC for high-reliability sites can comprehensively improve the problems of gold finger oxidation, deformation, dust, etc. caused by long-term use of traditional industrial control products. The European connector is used to replace the gold finger connection method, with 360-degree contact, sealed and dustproof, solid structure, anti-vibration, able to withstand a certain gravity, and ensure stable and firm connection. At the same time, this series of products has rich expansion capabilities, the whole machine supports PCI2.3 specifications, and is compatible with the customer's original function board, achieving a steady improvement in the overall system security performance and stability.
