Methods and devices for process editing, acquisition, process data protection for solar cell production apparatus

A process acquisition method for a solar cell production apparatus, the process acquisition method comprises:

• setting independently a control component in an execution unit for the first process data and a control component in the execution unit for second process data of the production apparatus of a solar cell production line, respectively, as a first control component and a second control component;
• the second process data is not the process data of the first process data;
• setting independently programmable logic controllers PLC for the first control component and the second control component, respectively, as a first control component PLC and a second control component PLC;
• wherein,
• the first control component PLC is connected with the second control component PLC by communication, and the first control component PLC is configured to receive the first process data and to control the operation of the first control component;
• setting a process decoder in each of the production apparatus, and the process decoder has hardware information of the production apparatus;
• verifying, by the process decoder, whether hardware information in the first process file is consistent with hardware information in the process decoder, after the production apparatus receiving the first process file;
• and
• importing decoded first process data in the first process file into the first control component PLC, so as to control the first control component to execute the decoded first process data, and the second control component to execute the second process data, in the case that the hardware information is consistent.

• the first control component PLC is connected with the second control component PLC by communication, and the first control component PLC is configured to receive the first process data and control the operation of the first control component;
• setting a process editor, a process decoder and an execution unit control software in a control host of the production apparatus, wherein, the control host stores hardware information of each of the production apparatus of the solar cell production line, and the process decoder has hardware information of the production apparatus;
• the process decoder is integrated in the process editor;
• and the process decoder and the execution unit control software are set to prohibit the direct transmission of the first process data between the process decoder and the execution unit control software;
• editing the first process data of the production apparatus via the process editor;
• in the case that the production apparatus is not the current production apparatus, the first process data is encrypted according to stored hardware information of the production apparatus and an encryption method, to obtain the first process file of the production apparatus;
• the first process file is transmitted to the process editor of the control host of the production apparatus;
• after the process editor of the control host of the production apparatus receives the first process file, the process decoder verifies whether hardware information in the first process file is consistent with hardware information in the process decoder, in the case that the hardware information is consistent, decoded first process data is imported into the first control component PLC of the production apparatus, to control the first control component to execute the decoded first process data, in addition, based on input second process data, the execution unit control software of the production apparatus controls a second control component to execute the second process data;
• and
• in the case that the production apparatus is the current production apparatus, the edited first process data is imported into the first control component PLC of the current production apparatus to control the first control component to execute the decoded first process data, in addition, based on input second process data, the execution unit control software of the current production apparatus controls the second control component to execute the second process data.
