The full beer bottle detection of beer filling production line

Abstract

At present, the amount of beer filling line detection equipment market is largely monopolized by foreign corporations with high price. In order to break the monopoly of foreign technology, and to improve domestic competitiveness of enterprises in beer production, we have developed the amount of beer filling line detection equipment of our own with independent intellectual property rights. Full bottles detection is one of the sub-topics. Firstly, multiple detection methods are compared in this paper, including infrared detection, ultrasonic testing, and high-frequency electric field detection. And finally we choose high-frequency electric field detection scheme. Sensor parameters are chosen. This paper focuses on the design of high-frequency driven circuit and signal conditioning circuit, including high-frequency small-signal resonant amplifier circuit, integrated broadband amplifier circuit, peak detector, and microprocessor signal processing circuit. Microchip ATmega64 is used to process digital signal. Substandard products are achieved to detect, to alarm, to remove. Bubble compensation is carried out in the procedure. The hardware circuit, which is based on ENC28J60 Ethernet controller, is designed to communicate with host computer, accurately, fast and conveniently. On the basis of the actual objects, a lot of experiments have been done. Experimental results show that beer bottle in a fixed orbit is the key to the stability of the detection system.
