Automatic filling machine based on industrial control computer and RS485 field bus to achieve the signal acquisition, processing, control and output, constitutes a cost-effective weighing system; the use of local area network to achieve the field monitoring computer and management computer communication; weighing software using modular approach using VC + + compilation. The actual operation shows that the system is reliable, easy to maintain and use, friendly man-machine interface, and has good control effect.

Automatic Filling machine adopts man-machine interface, display LCD module selects Delta's T6963C, the P1, P2, P3 ports of the main control chip AT89C52 are used as data port lines to exchange data with the outside, EA pin is connected to the +5V power supply, PSEN pin is connected to the OE terminal of the external 12C887, and the ALE pin is connected to the OE pins of the 74 series driver chips. T0, T1 timer mode, T2 adopts count reset mode.
Weighing control system in order to facilitate the operation of the user, the filling machine in the keyboard setup adopts the key multiplexing, through the software setting, in different display interface, the key function is different. The clock function of the control system is completed by DS12C887 chip, which has a perpetual calendar and can set the running time of the system. At the same time, the system can be set with a password, so that the system can work normally after reaching the running time and losing the password.
Weighing and filling machine through the SOL + WINCC software development of filling management system. The use of computers to achieve monitoring and control functions, through the programming software to realize the process and equipment control probe signals, liquid level, pressure, mixing, current signals: pumps and other facilities such as the state of the equipment, start and stop and other equipment data and the process of the Filling system to form a cause and effect conditions, to achieve the logic of interlocking control.
