[0021] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects described may be practiced without these specific details.

[0022] Combination Figure 1, an implementation mode of the present application. An equipment comprehensive management and evaluation system, comprising: a management module, a competitive product index acquisition module and an evaluation module, wherein the evaluation module compares and evaluates the stored equipment and external equipment according to the performance characteristics of the stored equipment recorded by the management module and the performance characteristics of the external equipment acquired by the competitive product index acquisition module; wherein the management module comprises: an input unit for inputting the overall performance characteristics and component performance characteristics of the stored equipment; an equipment database for storing the overall performance characteristics and component performance characteristics of the stored equipment; a clustering unit for extracting the overall performance parameters and component performance parameters of the stored equipment according to the overall performance characteristics and component performance characteristics of the stored equipment, and sorting the overall performance parameters and component performance parameters according to the equipment efficacy and component efficacy respectively; the input unit, ... The data base and the clustering unit are connected respectively; the competitive product index acquisition module includes: a collection unit for collecting external equipment information and extracting the performance characteristics of relevant external equipment; a transcoding unit for compiling the performance characteristics of the external equipment into a pattern or text information; a display unit for displaying the pattern or text information; the collection unit, the transcoding unit and the display unit are connected in sequence; the evaluation module is connected to the management module signal, and includes a shooting component for shooting the display content of the display unit; an identification unit for identifying the display content and restoring it to the performance characteristic information of the external equipment; a comparison unit for evaluating the external equipment and the equipment in stock respectively according to the performance characteristic information of the external equipment and the overall performance characteristics and component performance characteristics of the equipment in stock. In this embodiment, in order to realize the transmission of data from the external network to the internal network, this embodiment adopts a picture or text recognition method to convert the external network equipment information into a picture or text information, and then the shooting component shoots and recognizes and converts it, so as to effectively obtain the external equipment information without network interconnection, save labor costs, and improve the accuracy of information input.

[0023] Based on the above embodiment, further, the pattern or text information is a QR code pattern or Chinese character information. In this embodiment, the text and QR code information cannot transmit any program instructions, further avoiding the possibility of transplanting viruses into the intranet through coding. At the same time, the Chinese characters and QR codes in a unit image carry a large amount of information, which improves the efficiency of information transmission.

[0024] On the basis of one or more of the above embodiments, the present application further includes steps for evaluating external equipment and equipment in stock according to performance characteristic information of external equipment and overall performance characteristics and component performance characteristics of equipment in stock, including: obtaining equipment in stock whose overall performance characteristics and component performance characteristics are closest to those of external equipment, and evaluating whether there is equipment in the equipment library that is better than external equipment or closest to external equipment according to the sorting results of overall performance parameters and component performance parameters. In this embodiment, the closest equipment in the equipment in stock is selected for external equipment by performance parameters instead of equipment name or equipment type, and at the same time, whether there is overall performance characteristics or component performance characteristics of our equipment that are better than external equipment is obtained according to the sorting results of performance parameters, that is, evaluating whether we have products that are better than external equipment in all aspects or products that are partially better than external equipment. If it is partially better than external equipment, we can further carry out targeted research and development projects to level the equipment gap.

[0025] Based on one or more of the above embodiments, the present application further refers to Figure 2, the evaluation module also includes a technology reuse evaluation module. When receiving the task of establishing a new equipment R&D project, the technology reuse evaluation module obtains the stored equipment that is associated with the overall performance characteristics and component performance characteristics of the equipment to be developed from the equipment database for the equipment to be developed, and obtains the overall performance parameters and component performance parameters closest to the equipment to be developed as potential reusable technologies according to the overall performance parameters and component performance parameters of the associated stored equipment and the ranking results of the overall performance parameters and component performance parameters of the stored equipment as potential reusable technologies, and evaluates the feasibility of the potential reusable technologies for the reuse of the equipment to be developed by combining the potential reusable technologies with the equipment to be developed. In order to further improve the speed of industrial upgrading and the technical level of industrial products in my country, my country has carried out a comprehensive industrial level survey in recent years. All provinces, cities and key units have conducted corresponding technical surveys and filing processes for upstream and downstream units and various institutional production enterprises. The above actions have a positive role in promoting my country's technological development, especially making outstanding contributions to the breakthrough of technical difficulties in related equipment in my country. For units within the system, how to save R&D funds and comprehensively utilize existing technology reserves for new technology research and development is also an urgent problem to be solved at this stage. At present, the research and development of special equipment in my country is mainly carried out by several leading group companies and related second- and third-level subsidiaries. Due to the physical constitution and confidentiality requirements of the above-mentioned units, the technology transfer procedures within the same group are particularly complicated, and it is more difficult for different groups to share technology. However, at this stage, it is not realistic to transfer related technologies across units for the sake of confidentiality of some technologies. In order to improve the efficiency of equipment research and development, targeted management and evaluation strategies are proposed for existing equipment in storage, and the production unit, research and development unit and evaluation unit of the corresponding equipment can be traced back to the performance indicators of each equipment. In the establishment of new equipment research and development projects, in order to improve the efficiency of research and development, this application adopts a multi-equipment cross-query method to conduct a comprehensive investigation of existing equipment technology and research and development units, and comprehensively utilize existing technologies to save new equipment research and development time. For example, in this embodiment, when a new model of special vehicle needs to be developed, Party A proposes the purpose and performance requirements of the equipment. Assume that Party A needs an unmanned vehicle with a crawler walking mechanism and an off-road speed of not less than 25km / h. The vehicle needs to have an anti-interference communication distance of 20 kilometers and a 1.5km personnel infrared / radar detection capability, and its own weight does not exceed 3 tons.When Party A makes a request, the present invention can input the index parameters of the crawler walking mechanism, load-bearing body, communication system, detection system, etc. into the index library according to the above-mentioned indexes, and the corresponding performance parameters of the existing equipment can be listed for each index in the index library. For example, for the above-mentioned index, after inputting the crawler walking + 25km off-road speed, various equipment with the above-mentioned equipment capabilities in the existing equipment can appear. After further inputting the dead weight not exceeding 3 tons, the overweight equipment can be screened out according to the dead weight index, and the qualified related equipment walking mechanism and the corresponding chassis and body technology as well as the corresponding technology research, production and testing units are retained. The reusability of the above-mentioned technology is further evaluated, and further communication is conducted with the R&D unit based on the evaluation results to effectively implement the reuse technology.

[0026] On the basis of one or more of the above embodiments, the present application further includes the process of obtaining the equipment in stock that is associated with the overall performance characteristics and component performance characteristics of the equipment to be developed from the equipment database for the indicators of the equipment to be developed, including: inputting the overall performance characteristics and component performance characteristics of the equipment to be developed into the indicator library respectively, and screening out at least one preferred solution for each performance characteristic. In this embodiment, since there is not a complete correspondence between the equipment to be inspected and the equipment in stock, in the case of a large gap in the overall performance characteristics, this embodiment also adds a performance characteristic retrieval method, such as splitting the equipment to be inspected into the walking mechanism, chassis bearing mechanism, power mechanism, communication mechanism, firepower mechanism and other component performance characteristics to retrieve products with similar technical parameters to each component, and then further judging whether there is a possibility of integration or reference for the product technology of each component by the research and development team.

[0027] On the basis of one or more of the above embodiments, the present application further divides the component performance characteristics into three levels according to the weights, wherein the first-level performance characteristics include the performance characteristics of the main system of the equipment to be studied, the second-level performance characteristics include the subsystem unit indicators that mainly constitute the system, and the third-level performance characteristics include the component indicators of each functional component. The first-level performance characteristics and the second-level performance characteristics are necessary input indicators, and the third-level performance characteristics are non-essential input indicators. In this embodiment, since the current equipment is a large system integration product, its various components are also provided by multiple R&D and supply units, this embodiment further classifies the unit-level technologies such as general research and sub-research. However, overly detailed classification will lead to a large amount of redundant information, so this application only has three levels of weights, and the third level is a non-essential input indicator to improve the convenience of early retrieval, and after determining the reusable technology, it is further refined through the three-level performance characteristics and detailed technical characteristics.

[0028] On the basis of one or more of the above embodiments, the present application further provides a process for entering component performance characteristics of warehoused equipment, including extracting component performance characteristics of each warehoused equipment, and classifying the component performance characteristics into three levels according to weights.

[0029] On the basis of one or more of the above embodiments, the present application further includes the process of evaluating the feasibility of the potential reusable technology for the equipment to be developed by: judging the degree of fit of the potential reusable technology to the equipment to be developed, and if at least five performance characteristics of the potential reusable technology meet the second level and all the first level performance characteristics meet, then the potential reusable technology is judged to be a reusable technology, otherwise it is a non-reusable technology. This embodiment improves the screening efficiency and further saves human resources through automatic evaluation.
