Aiming at the lack of real-time data acquisition

storage and remote monitoring in the traditional low pressure casting process

low pressure casting machine data collection and implementation of remote monitoring system through the WEB client to access the database was developed by taking C8051F350 microcontroller as control core

microcontroller internal A/D achieving analogue acquisition

and using TLP521-4chip as the key component of digital data acquisition as well as sending data by WIFI on the PC side with the help of the development of software to realize the data receiving

analysis and storage.The system structure

working principle

hardware and software design were described.The developed system has the features of high precision and stability

which can achieve a number of ananlogue and digital long cycle real-time acquisition and transmission.
