Abstract

The invention provides a multichannel digital measurement and control system based on an I2C bus. The multichannel digital measurement and control system comprises a master controller unit, an I2C busisolation and conversion unit, an I2C bus driving conversion unit, an I2C bus parallel input / output conversion unit, a multichannel input / output isolation and conversion unit and a user interface unit. The system makes parameter setting flexible and convenient, can perform quick, stable and seamless switching and can also adapt to working occasions of complicated electromagnetic environment, longer transmission distance and high communication accuracy, and the reliability and rapidity of the multichannel digital input / output measurement and control system are ensured.

Description

technical field [0001] The invention belongs to the field of embedded technology, and in particular relates to a multi-channel digital measurement and control system based on an I2C bus. Background technique [0002] The research and operation practice show that the I2C bus communication method using the conventional method will often be disturbed in the application site with strong electromagnetic interference (such as the ship integrated power system mentioned above, which is one of the very typical application environments). , the reliability can not be improved, therefore, it can not meet the information exchange demand of the "blowout" growth of the system. Therefore, it is urgent to apply the mature, reliable, and real-time I2C bus technology to the multi-channel digital input / output measurement and control system in the ship's integrated power system to improve the efficiency and reliability of the ship's internal information exchange. sex.
