The invention provides a PLC automatic control system comprising a central control system, and an information acquisition system, a remote terminal and a controlled terminal which are connected with the central control system. The controlled terminal is connected with the information acquisition system. The controlled terminal comprises a powder conveying system and a powder reaction system. The information acquisition system comprises a temperature acquisition unit, a pressure acquisition unit, a humidity acquisition unit and a CCD image sensor. A data distribution unit is connected between the remote terminal and the central control system. According to the PLC automatic control system, continuous work of the whole PLC automatic control from input of material to end of reaction is realized so that quality fluctuation caused by uncertainty of manual operation in the intermediate process can be reduced and labor productivity can be enhanced. Besides, temperature, humidity, pressure, reaction time and material feeding automatic control are mutually restricted and controlled, and alarming is performed and the next reaction step is stopped if any one of the items cannot meet the prescribed requirements.
Description
technical field [0001] The invention relates to the field of automatic control of powder reactions, in particular to a PLC automatic control system. Background technique [0002] For powder reaction technology, the industry usually adopts intermittent (two or three stages) and manual control methods for production, which has low production efficiency and poor product quality. Contents of the invention [0003] Aiming at the problems of low production efficiency and poor product quality in existing powder reaction technology using manual control, the present invention provides a PLC automatic control system to realize automatic control and monitoring. In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: The present invention includes a controlled terminal, an information collection system, a central control system, and a remote terminal, and the central control system is connected to the information collection syst...
