The invention discloses an access method, device and equipment and a computer readable storage medium, which are applied to the technical field of computers, and comprise the following steps: loading a consistency label list corresponding to an authorized access consistency domain; when an access request is initiated to a target consistency domain in the shared memory, performing permission verification on the access request through the consistency label list and the target consistency domain; when the permission verification is passed, determining whether an access conflict exists or not through a local access state cache and the type of the access request; if the access conflict exists, a controller arbitration engine is triggered, and the access request is executed according to an arbitration result; and if the access conflict does not exist, executing the access request. According to the method, the consistency label list and the access state cache are formulated for each device, the consistency problem existing when multiple devices access the shared memory in an existing system is solved, and efficient, low-conflict and flexible consistency guarantee can be achieved under the scene that multiple devices concurrently access the shared memory.

The invention discloses a code file metadata consistency management and control method in a low-code system, and relates to the field of low-code systems.The method comprises the steps that a code object set is extracted from a structured model code file through a code object extraction large language model; and graph static consistency checking is carried out on the code object set and the constructed data model metadata graph, so that the inconsistency problem of meta-model association errors or missing and the like in a page model and a process model can be effectively avoided. In addition, front-end and back-end static consistency checking is carried out on front-end and back-end code object sets in combination with front-end and back-end code jump URL routing configuration files, the null value obtaining error caused by inconsistent transmitted parameter variable names of front-end and back-end associated code files can be effectively avoided, dependence on experience of developers can be effectively reduced, and the development efficiency is improved. And the inconsistent position of the model code file is quickly found and positioned, and the operation stability of a low-code system is effectively improved.

The invention belongs to the technical field of intelligent control, and particularly discloses a multi-agent system consistency method based on adaptive shunt integral PI control, and the method comprises the following steps: obtaining the displacement, speed and time-varying disturbance data of each agent in a second-order multi-agent system under an undirected graph; calculating a displacement consistency error and a speed consistency error of each intelligent agent; an adaptive shunt integral PI controller is constructed, the controller comprises a proportional term, a shunt integral term and a disturbance estimation term, and the shunt integral term reduces system overshoot through a symbol switching mechanism; dynamically adjusting a disturbance estimation item, and describing the dynamics of a shunt integral item through a hybrid system model; and determining a self-adaptive shunt integral PI controller and constraint conditions of related control parameters in the self-adaptive law so as to enable the system to realize consistency under time-varying disturbance.

The embodiments of the present disclosure disclose a data consistency processing method and device under a micro-service architecture, a device and a medium. Based on a preset period, a plurality of groups of service data corresponding to a plurality of services are acquired from data sources of the plurality of services of a target application. Based on a preset comparison rule, the plurality of groups of service data are subjected to data consistency comparison to determine whether there is consistency problem data having a consistency problem among the plurality of groups of service data. In response to the existence of the consistency problem data, a data consistency task of the consistency problem data is generated. Based on the data consistency task, data compensation and repair processing is performed on the consistency problem data, which includes at least one of the following operations: updating data, synchronizing data, and triggering an associated business process operation. The present disclosure can flexibly and accurately determine the consistency problem data in the plurality of services through the preset comparison rule, and can quickly repair the consistency problem data.
