Description

Technical Field

[0001] The invention relates to the technical field of electric control systems, in particular to an automatic control system for cement production and a control cabinet thereof. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material, which forms a slurry after adding water and mixing. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime pozzolana cement. It is used to bond concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water.

[0003] The basic production processes of cement include mining and crushing, raw material pretreatment, sintering and calcining (denitrification treatment), grinding and packaging and storage. With the improvement of automation level and optimization of control modules, the processing devices corresponding to multiple processes can be connected in series and work together, and are uniformly coordinated by a complete control system, which greatly improves the efficiency of cement production.

[0004] However, the existing production automation control system has the following shortcomings:

[0005] Since there is a certain time difference in the ordering of each process in cement production, and material transfer is required between some corresponding devices, the existing control system is mainly used to start and stop each device, and the conditions for the operation of the system rely on multiple electrical components. Affected by various external factors, the commands issued by the system may not be able to be fed back to the pre-processing device in time. Since some processes do not require personnel to stay, the traditional control system cannot obtain the status information of each device in time, resulting in problems in a certain link, which will affect the operation of the entire process.

[0006] Therefore, we proposed a cement production automation control system and its control cabinet to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a cement production automation control system and a control cabinet thereof. The image data collected by a corresponding camera can be input into a data review unit in real time to determine whether the equipment status conforms to the command content. If the conclusion is contradictory, the single chip will send the same command to the device again, and then the secondary judgment module will directly retrieve the equipment status graph according to the previous path to determine whether the equipment is executed. If the conclusion is correct, the detection signal can be quickly imported into the single chip microcomputer to control the subsequent processing equipment normally. Otherwise, the secondary judgment module controls the opening of the alarm light to remind peripheral staff to quickly rush to the single chip microcomputer to check the content displayed on the display screen, including the specific location of the faulty equipment and whether the command is received, and manually control the physical automatic control knob to perform emergency processing in time to solve the problems raised by the above background technology.
