Abstract

The invention discloses a plc protocol based data collection optimized method, and belongs to the technical field of data collection optimization. The method comprises the following steps that S1) a power supply is switched on, and different parts are connected to the network; S2) communication protocols of a PLC are used, an instruction is sent, a data collector identifies the instruction and then collects data, and obtained data is encrypted; S3) the obtained data is preprocessed and divided into multiple parts; S4) the different parts are found, and analyzed and processed, and the parts after processing and optimization are recovered to a main body; and S5) the processed data is reported to an Internet server via PLC communication protocols, stored in a data memory and then output. Thedata collection optimized method can be used to improve the reliability and operation speed of the system, can be conveniently mastered and operated by a user, and can be used to enhance the safety ofdata file storage.

Description

technical field [0001] The invention relates to the technical field of data acquisition optimization, in particular to a PLC protocol-based data acquisition optimization method. Background technique [0002] PLC (Programmable Logic Controller, Programmable Logic Controller) is a device dedicated to industrial control. PLC usually controls the bottom layer, collects sensor signals and controls field actuators through configuration logic. The communication protocol of PLC indicates which methods can be used To connect with third-party software, the commonly used communication protocols include Ethernet protocol, MUDBUS protocol, etc. [0003] The data encryption algorithm is a symmetric encryption algorithm. The basic process of data encryption is to process the original plaintext file or data according to a certain algorithm, making it an unreadable piece of code, usually called "ciphertext", making it The original content can only be displayed after entering the correspondi...
