7results about How to "Reduce disputes" patented technology

The invention discloses a building supply chain transparent communication system and method based on a block chain, and relates to the field of block chain technology and building supply chain management, and the system comprises the following components: a block chain underlying network, an intelligent contract module, a terminal collection node, an authority management module and a communication interaction module. According to the invention, by deploying the intelligent contract module, the business rules of automatic payment, performance verification and dispute early warning are realized, and the application of a dynamic acceptance weight verification algorithm and a dynamic threshold dispute early warning mechanism enables the payment trigger logic to better meet the actual demand of a project, improves the payment accuracy by 27%, reduces disputes caused by fuzzy acceptance standards, and improves the payment efficiency. Meanwhile, the dispute early warning mechanism monitors on-chain performance data in real time, automatically triggers early warning when the data deviates from a preset threshold value, synchronously pushes early warning information to related nodes, and generates an on-chain early warning certificate.

In the implementation process, between every two adjacent compartment wall plates, the first butt joint plate is detachably connected with the main plate body butt joint part of the first compartment wall plate, and the butt joint plate is detachably connected with the main plate body or the main plate body butt joint part of the second compartment wall plate.

The bladder blood clot remover comprises a hollow sleeve and an inner core, a water inlet is formed in the tail of the hollow sleeve, the head of the hollow sleeve is tilted upwards, a long hole is formed in the back side of the tilted part of the hollow sleeve, and the length direction of the long hole is consistent with the length direction of the hollow sleeve; the water inlet is provided with a closing device; the inner core is inserted into the hollow sleeve from the tail of the hollow sleeve, the diameter of the head of the inner core is larger than that of the middle of the inner core, a groove is formed in the head of the inner core, and the elastic ring is arranged in the groove in a sleeved mode. And when the inner core is inserted into the hollow sleeve from the tail part of the hollow sleeve, a piston effect is formed through the elastic ring and the middle part of the hollow sleeve. The bladder blood clot remover has the advantages of being simple and reasonable in structure, convenient to use, clean in blood clot removal, high in efficiency and the like.

The invention provides an electronic document encryption and decryption system and method based on a block chain, a medium and equipment, the system comprises a block chain evidence tracing layer, an electronic document security layer and a security access and identity management layer, and the block chain evidence tracing layer is used for tracing an evidence uploaded by data; the electronic document security layer comprises an uploading node processor and a downloading node processor, and is used for encrypting uploaded data by using an uploading data node and decrypting block data by using a downloading data node, and the encryption and decryption processes are processed based on a self-defined ciphertext policy attribute proxy re-encryption mechanism; and the security access and identity management layer is used for verifying the security attribute of the node and performing management. According to the method, while full-link traceability and tampering prevention of the document process are realized, dynamic and fine-grained regulation and control of the access permission of the encrypted document are supported, and authenticity, privacy and controllable sharing of data are comprehensively guaranteed.

The invention discloses an order agricultural performance evidence storage and dynamic settlement method based on satellite-ground cooperative verification and privacy calculation, and belongs to the cross technical field of intelligent agriculture and financial science and technology. According to the invention, crop growth data is collected, encrypted and uploaded to a block chain evidence storage platform in real time through an Internet of Things node which is deployed in a farmland and has a trusted execution environment and a hardware encryption module; and meanwhile, acquiring a multi-temporal satellite remote sensing image of the target land parcel, extracting a vegetation index characteristic curve, and calculating a space-time consistency correlation coefficient with the ground data to realize anti-counterfeiting verification of the ground evidence data. In addition, the farmer side generates compliance proof without leaking original production details by using a zero-knowledge proof protocol, and the compliance proof is automatically verified by an intelligent contract. In the settlement stage, the intelligent contract calls an external market oracle machine to obtain a real-time market price, dynamic price adjustment based on a preset economic model is executed in combination with a peasant household block chain credit score, and automatic fund settlement is completed through a programmable payment interface. According to the invention, three problems of data source counterfeiting, business privacy leakage and price game default in order agriculture are effectively solved, and credible, private and fair automatic performance and settlement are realized.

The invention provides a method for transmitting process steps in a quality tool, relates to the technical field of manufacturing industry management and data processing, and realizes automatic transmission of the process steps and special characteristics among APQP, PFMEA, CP, DFMEA, MSA and SPC modules by fusing a bill of materials, production parameters and process images to generate an adaptive semantic association model and combining an adaptive dynamic topology network. According to the process steps, an APQP flow chart is generated and then automatically transmitted to a PFMEA generation report, special characteristics are imported into APQP from a DFMEA list and marked on CP, and finally the APQP is output to an MSA / SPC module to generate a measurement task and a process capability report, so that the consistency of data in different files is ensured. Compared with a fixed transmission path described by a file, by dynamically adjusting the network topology weight, monitoring the data integrity in real time and automatically repairing format errors or omissions, an automatic transmission mechanism remarkably improves the collaboration efficiency between modules, and errors caused by manual intervention are reduced.
