The design of syrup concentration detector based on ADuC812 single-chip and BP ANN

In order to achieve online testing the syrup concentration in the process of boiling sugar, the syrup concentration detector was designed by taking the ADuC812 chip as the microprocessor; the radio frequency and PLL technology were used in it. These had achieved real-time monitoring the syrup concentration. At the same time, taking into account the impact of temperature on the syrup concentration, the temperature was compensated by BP neural network. The methods of how to implement the neural network algorithm on the microcontroller were discussed. The experiment results show that the detector has high accuracy, fast response; it is meeting to the requirements of syrup concentration on-line measurement.
