Abstract
This introduces the deviceofsingle-tank liquid level control,including the analysis of a single-bit control system to establish the mathematical model, and the establishment of a single-bit control system solution to control the level of the digital simulation model by automatic control system process, As an level control experimental device , single-bit control system has some experimental functions, whichcan be targeted at first-order control, and can be used aslaboratory equipment for liquid level control algorithm to show that.
This liquid level control devicewhich selectsthe experimental liquid level / pressure for the control as objects, designed AT89C51 for the master chip, supported by pressure sensors, A/D0809 as well as the liquid level relay control system.it focused on single-chip AT89C51 on Machine data acquisition and processing system and C language on the data transfer module design process, the working process.
The study ,summarized single-chip's advantages based on the liquid level control system:small size, simple practical application system,low cost, a high cost performance, the system susceptible to interference, high reliability.
