The Design Of Automatic Monitoring And Control System For The Production Line Of Concrete Activator

In the domestic concrete activator enterprises, above 95% are the small andmedium-sized enterprise, furthermore, production craft and equipment of the concreteactivator is backward, automaticity is low, personal error is big, the production efficiency islow, therefore, in view of the domestic multitudinous similar small and medium-sizedenterprise, developing automatic monitoring system in the production line of the concreteactivator has the certain application value and the practical significance.This article, in view of the concrete activator production line of some building materialslimited company in Shijiazhuang, uses two levels of computer controls that PC makes the onposition machine and four piece of singlechips make the lower position machine, toconstitude small Distributing Control Systems, realizing the monitoring to the producingscene. The hardware aspect has designed the simulation quantity input/output circuit, digitalquantity input/output circuit, serial communication circuits between singlechips and PC, andhardware system interference circuits;The software aspect has established on positionmachine monitoring software based on the virtual instrument developing platform-LabVIEW7 Express, communication software between the on position and the lower position machineand the lower position machine industrial control software.This system software design is simple, clear, and the user operation contact surfacedirect-viewing, friendly, its operation is simple. Multi-level and multithreading modulardesign has guaranteed the system reliability and the extension. Moreover, the hardware circuitdesign of circuit precision, reliable performance and low cost advantages, will help topromote the automation process in the production line of concrete activator...
