[0026] Please refer to Figures 2-3 In an embodiment, the scraper identity mark recognition system 10 comprises an electronic tag 11 installed on the scraper 201 of the scraper chain 200 and a reader 12 installed on the side of the sunroof middle slot 100, the chain of the scraper chain 200 is divided into a plurality of specific coding areas through the electronic tag 11, the reader 12 reads the tag information of the electronic tag 11, the tag information includes tag number and position coordinates, and generates scraper positioning information according to the tag information, and the reader 12 is in communication connection with the controller 30 to transmit the scraper positioning information to the controller 30.

[0027] The scraper chain information acquisition and analysis system 20 comprises a Hall sensor 21 installed on the plug-in plate of the sunroof middle slot 100 and a signal processor 22 installed on the side of the sunroof middle slot 100, the Hall sensor 21 is in communication connection with the signal processor 22, the voltage signal of the passing scraper chain 200 is collected through the Hall sensor 21 and transmitted to the signal processor 22, the voltage signal is analyzed and processed through the signal processor 22 to obtain the scraper and chain ring discrimination information; the signal processor 22 is in communication connection with the controller 30 to transmit the scraper and chain ring discrimination information to the controller 30.

[0028] In a specific embodiment, the entire chain of the scraper chain can be divided into specific coding areas due to the uniform distribution of a certain number of electronic tags 11 on the entire chain. When the scraper chain passes through the reader 12 and the Hall sensor 21 installed on the middle slot 100 of the open window, the reader 12 reads the tag information of the electronic tag 11 of the scraper passing through, so as to know the number and position coordinates of the scraper contained in the tag information, i.e. the scraper positioning information of the scraper, and the reader 12 sends the scraper positioning information to the controller 30; at the same time, the Hall sensor 21 collects the voltage signal when the scraper passes through, and sends the voltage signal to the signal processor 22, and the signal processor 22 analyzes and compares the voltage signal with the preset scraper voltage signal, and judges that the voltage signal represents the scraper, and sends the judgment information to the controller 30, and the controller 30 encodes and positions the scraper according to the received scraper positioning information and judgment information, such as encoding 1, and the controller 30 takes the installation position of the reader 12 and the Hall sensor 21 as the initial position, and according to the real-time received information, takes the current passing scraper as the reference scraper, and combines the position coordinates of the scraper with the initial position coordinates, to realize real-time positioning and tracking of the scraper. Since the scraper and the next scraper are connected by a plurality of chain links, the chain links are divided into flat links and vertical links, which are alternately connected.
