FDC2214-based paper quantity detection system and method

Abstract

The invention discloses an FDC2214-based paper quantity detection system, which comprises a signal acquisition module, a signal processing module and a display module, and is characterized in that thesignal acquisition module adopts a capacitive sensor FDC2214, and the signal processing module comprises a single chip microcomputer; the signal acquisition module adopts a capacitance sensor FDC2214to acquire a paper capacitance signal between preset metal polar plate areas and sends the capacitance signal to the single-chip microcomputer; the signal processing module performs data processing on the received capacitance signals, stores the capacitance signals into a database and detects the number of paper sheets; and the display module displays the input state capacitance value and the detection state paper quantity value. According to the system and the method, through cooperation of the capacitance sensor and the single-chip microcomputer, paper placed between the two metal polar plate areas is converted into an accurate capacitance signal, so that paper quantity detection can be realized. And compared with the traditional technologies such as the existing manual counting and currency counting machine, the system has the advantages of high precision, low power consumption, low noise, strong anti-interference capability and low cost.

Description

technical field [0001] The invention relates to an FDC2214-based paper quantity detection system and method, belonging to the field of sensing detection technology and single-chip microcomputer control technology. Background technique [0002] my country is a big country in the printing industry. Low-cost, fast, convenient and high-quality integrated services are the general requirements of today's printing industry. Processes are constantly being improved, and new technologies such as big data are constantly emerging. During the transfer of printed paper pallets between processes, the accuracy of the quantity is always the most basic requirement. In order to meet this requirement, it is of great significance to the entire industry to develop a set of paper quantity detection devices that are fast, efficient, low in cost, and have little impact on paper quality. [0003] In the printing and packaging industry, the most important method for accurate counting and packaging of...

Problems solved by technology

Manual counting requires a large number of workers to coordinate counting, which wastes a lot of manpower and time, and the counting is greatly affected by subjective factors

Money counter is a typical mechanical counting equipment. Because it will contact with the blade of the mechanical equipment when counting, the way of counting the paper through the mechanical equipment is easy to cause damage to the quality of the paper. When the machine is running, it will generate a lot of noise. In addition, the mechanical equipment There are strict requirements on paper specifications and the number of counts at one time

The above two paper counting methods require a lot of manpower and material resources, increase operating costs and reduce production efficiency, and the blades that are in direct contact with paper have a serious impact on paper quality
