The invention discloses a making method of corn-wheat composite noodles added with arachin, and belongs to the field of food processing. The corn-wheat composite noodles are prepared from the following raw materials in percentage by mass: 70-76% of wheat flour, 21-25% of corn flour, 1-4% of arachin, 1-2% of table salt and 0.1-0.5% of dietary alkali. When the corn-wheat composite noodles are prepared, the overall quality of the corn noodles is improved in a mode of adding the arachin, the internal network structure of the noodles is more uniform, the quality is better, the requirements of zero food additives are met, and the addition amount of the corn flour is also increased.

The invention discloses an industrial non-intrusive measurement data transmission method and system based on wavelet transform compression. The method comprises the following steps: designing a data transmission protocol for I format information; the power system collects the equipment type, the operation mode, the real-time power, the real-time current, the transient power and the transient current on the production line, and uniquely encodes the equipment type and the operation mode; the power system monitors the start-stop state of electric equipment on the production line; transmitting a remote measurement value and a remote signaling value to a monitoring system; directly transmitting real-time power and real-time current through a network; the transient power and the transient current are compressed and then transmitted; the start-stop state of the electric equipment is directly transmitted through a network; data encryption is carried out before transmission; and the monitoring system carries out data decryption, verification and error processing on the received data. According to the invention, effective compression transmission of transient power and transient current data is realized, and high requirements of a modern industrial automation system on real-time performance and accuracy are met.
