Plastic packaging materials testing system based on internet of things and cloud technology

A plastic packaging material testing system comprising at least one remote testing laboratory system and a cloud computing center, wherein

• the remote testing laboratory system includes:
• a number of test units, each test unit having at least one packaging material testing instrument embedded with an identification code, the identification code including manufacturer information, instrument information and batch information, the identification code being preset in a memory of the packaging material testing instrument, the packaging material testing instrument being coupled with a sensor group and a data transceiver module (I), the sensor group detecting working environment data of the packaging material testing instrument, the packaging material testing instrument testing packaging materials, storing test data in an encoding format and transmitting the test data via the data transceiver module I, and
• at least one data acquisition server, the data acquisition server having a data transceiver module (II), the data acquisition server receiving the test data in the encoding format sent out by the test units via the data transceiver module II and processing the test data, the data acquisition server achieving automatic collection, storage, analysis of the working environment data and the test data, the data acquisition server being connected with the cloud computing center;
• and
• the cloud computing center includes
• at least one of a private cloud and a public cloud, for the private cloud, data being stored as a separate group of data in a database server based on a private infrastructure which is provided by a system provider, the system provider providing control of data, data security and service quality, and for the public cloud, a system provider ensuring system running and providing data service from a third party provider,
• wherein the cloud computing center performs data communication, data storage, data processing, report downloading and page displaying between customers and the remote testing laboratory system,
• and wherein the test data in the encoding format is packaged according to an equipment data frame that includes sensor information, an information acquisition device communication frame that includes test parameters and other information data which is collected by auxiliary information acquisition system, and a control frame that makes a data server control equipment test units by using line directives, wherein:
• in the equipment data frame, a frame head includes a frame sync byte, and bytes representing equipment ID, test ID, and test type information, a data section is formed of a plurality of bytes divided into four parts according to different reported information, which are equipment information, testing parameters, real-time data, and testing results, each part having a variety of frame formats according to specific content in the reported information and the frame formats being distinguishable from one another by feature coding within the frame head, and a frame tail saves a verification code which is a result of exclusive OR operation of the bytes of the frame head and data section byte-by-byte;
• the information acquisition device communication frame includes three parts, which are a frame head, data and frame tail, wherein the frame head part includes a frame sync byte, and bytes representing equipment ID, test ID, equipment type, reserved information, and frame format coding information, the data part contains bytes representing sample information and operator information that are sent to the data acquisition server and the test units, and the frame tail saves a verification code which is a result of exclusive OR operation of the bytes of the frame head part and the data part byte-by-byte;
• and
• in the control frame, a frame head includes a frame sync byte, and bytes representing server ID, target instrument ID, reserved information, and feature code information, a data section is formed of a plurality of bytes holding instructions, and issues the instructions which include instrument shutdown, call instrument time, set instrument time, call instrument sensor, switch information, switch control, call instrument parameters, start or stop tests, and call instrument log file, and the frame tail saves a verification code which is a result of exclusive OR operation of the bytes of the control frame byte-by-byte.
