In order to facilitate a better understanding of the innovative aspects of the present invention for those skilled in the art, the structure of the brand switching station will first be described. As shown in fig. 1, the brand exchanging station is installed in the material conveying pipe arrangement area between each feeder and each product manufacturing machine, and mainly comprises a feeder end interface station (comprising a plurality of inlet ends), a product manufacturing machine end interface station (comprising a plurality of outlet ends), an inner straight pipe, an elbow pipe, a high-level pipeline suspension structure, a low-level pipeline supporting structure and the like. The pipeline connection in the brand exchange station is basically based on a unique grid line design, namely, after an input port (an inlet end) and an output port (an outlet end) are determined, the pipeline connection is realized through a unique pipeline, the pipelines for feeding and discharging materials are respectively positioned in two planes with different heights, and each pipeline component is manufactured by a factory according to standards so as to realize the random switching of the material conveying pipelines.
Path connecting the inlet end to the outlet end within the brand exchange station: if the number of inlet end interfaces (connected from each pipeline of the feeding machine) of the brand exchange station is n, the number of outlet end interfaces (connected to each product manufacturing machine) of the brand exchange station is m, and n is larger than or equal to m and larger than or equal to 1, the number of pipeline connecting paths which can be theoretically realized is n according to the principle of arrangement and combination
. Under the conditions of multiple brands, multiple pipelines and multiple connecting paths, the requirements on the accuracy and the reliability of the pipeline connection in the brand exchange station are obviously higher.
The following describes the principle of monitoring the switch of material grade based on bimodal signal detection with reference to fig. 2.

The dual-mode signal means that after a certain material pipeline in the brand exchange station is disconnected with the inlet end and the outlet end of the brand exchange station, a lead wire attached to the material pipeline is simultaneously disconnected with a first relay arranged at the corresponding inlet end and a second relay arranged at the corresponding outlet end (namely, after the certain material pipeline in the brand exchange station is disconnected, the connection of only one first relay and one second relay can be simultaneously disconnected, namely two falling edges appear simultaneously, which is a mode one), and after the certain material pipeline is connected with the inlet end and the outlet end of the brand exchange station, the lead wire attached to the material pipeline can connect the first relay and the second relay arranged at the corresponding inlet end and the corresponding outlet end in series to form a passage (namely, after the certain material pipeline in the brand station is connected, only one first relay can be simultaneously connected with one second relay, i.e., two rising edges occur simultaneously, which is mode two), which are collectively referred to as a bimodal.
Signals of two relays (a first relay and a second relay) in the first mode and the second mode are changed simultaneously, unique codes (such as addresses or numbers) associated with corresponding feeders and product manufacturing machines are configured for each first relay and each second relay, and the actually switched feeders and product manufacturing machine codes can be determined according to the detected codes of the first relay and the second relay corresponding to the bimodal signals, so that the change of the connection relation between the feeders and the product manufacturing machines caused by pipeline switching is determined, on the basis, the actually switched feeders and product manufacturing machine codes can be compared with the feeders and product manufacturing machine codes switched in advance according to production scheduling instructions through a judging unit (which can be realized by running a switching result judging program pre-installed in a PLC) of the monitoring controller, and judging whether the material brand switching is accurate or not, outputting a judgment result, and prompting the result by adopting different sound and light and pictures. The working process of the material grade switching and monitoring system based on bimodal signal detection for tobacco shred grade switching and monitoring is shown in figure 3.
