detailed description

The content of the present invention will be further described below in conjunction with the accompanying drawings.

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

The invention provides a method for establishing a database of outcrop rocks in the field, which comprises the following steps:

1) Collect existing field outcrop information, set up field outcrop text information template library and field outcrop picture template library; Wherein:

The outdoor outcrop picture template library is to collect photos of outcrop rocks in the wild with digital cameras, obtain rock thin slice pictures through polarizing microscopes, cathodoluminescence microscopes, and scanning electron microscopes, and perform image processing and save them as jpg format files. The template library for outcrop pictures in the wild includes Unique picture code and storage path, wherein the content of the field outcrop picture template library includes overall photos of field outcrops, partial photos, photos of some special phenomena, and rock thin-section polarizing microscope, cathodoluminescence microscope, and scanning electron microscope pictures.

3) Integrate the field outcrop position database, field outcrop occurrence database, field outcrop rock information database and field outcrop cause analysis database, and connect with the field outcrop database after fusion. The field outcrop database performs field outcrop information content for the four databases according to the rules. Combination, and use the reasoning engine to promote the fusion of the outcrop database and the four databases to complete the establishment of the outcrop database.

In the above step 3), the rules are as follows: define S as a rule set, C={C1, C2...Cn} as a conditional attribute set, V=(Vc1, Vc2...Vcn) as the value of the conditional attribute and decision attribute Domain, D is the decision attribute set, (d1,d2,d3...dv) is the decision value. The rule is: if the input condition attribute C1 is a certain value Vc1 in the value range V, then the decision attribute D is the corresponding decision value d1, that is, the attribute corresponding to the corresponding field when the output satisfies Vc1; if two condition attributes C2 and C3 are input , where C2 is a certain value Vc2 in the value range V, and C3 is a certain value Vc3 in the value range V, then the decision attribute D is the decision value d2, that is, the attribute corresponding to the corresponding field when the output satisfies Vc2 and Vc3.

For example, when the input condition attribute C1 is the outcrop code, D is the rock name, and Vc1=LT001, then output the rock name of the outcrop when the outcrop code is LT001.

In the above step 3), as shown in Figure 1, the reasoning engine includes the following steps:

(1) Matching: Whether the relevant facts of the current solution problem in the outcrop database match the condition part of the rule in the outcrop knowledge base. If the two match, enable this rule, enter step (3) to execute according to the execution operation part of the rule; if there are multiple rules at the same time, the condition part matches the relevant facts of the problem to be solved, then enter step (2).

(2) Conflict resolution: When the condition part of more than one rule matches the relevant known facts, it is necessary to decide which rule should be enabled first. This process is called conflict resolution. Priority is set for the condition part of all rules in advance. When there are multiple rules whose condition part matches the relevant facts of the problem to be solved, the rule with the higher priority of the condition part is given priority.

(3) Executing operation: Execute the operation part of enabling the rule, obtain new facts after performing the operation, and send the obtained new facts into the current outcrop knowledge database. While other rules can be reasoned using new facts to get knowledge closer to problem solving.

Above-mentioned step 3) in, the fusion method of described field outcrop position database, field outcrop occurrence database, field outcrop rock information database and field outcrop cause analysis database comprises the following steps:

(1) An outcrop can be uniquely determined according to the code of the outcrop database. According to the location of the outcrop, the photo, nature of the outcrop, cause of the outcrop, and occurrence of the outcrop can be retrieved synchronously.

(2) According to the fields such as the nature of the outcrop in the outcrop rock information database, fuzzy search the sentence meaning database, and search out the outcrop position satisfying the same similar nature, the cause of the outcrop, the outcrop occurrence, and the outcrop photo, thereby realizing the field outcrop position database, Integration of field outcrop occurrence database, field outcrop rock information database and field outcrop cause analysis database.

Above-mentioned each embodiment is only for illustrating the present invention, and each step all can be changed to some extent, on the basis of the technical solution of the present invention, all improvements and equivalent transformations carried out to individual steps according to the principles of the present invention should not be excluded outside the protection scope of the present invention.
