The utility model relates to a kind of cap type pier block tool for ship sub-assembly construction, including steel structure portable cap and concrete cement pier block, steel structure portable cap is detachably sleeved at the top of concrete cement pier block;Steel structure portable cap includes a roof, and the edge below of the four edges of roof is respectively welded with side edge reinforcing plate, and form the groove of bottom surface opening;Concrete cement pier block includes pier block body, and two dumper insertion holes are set in the lower part of its opposite sides, and pier block dumper insertion hole penetrates concrete cement pier block.The utility model effectively reduces the cost of all-steel pier block, solves the problem that pure concrete pier block is easily damaged and cannot be fixed linear section, has the advantages of low cost, good durability, strong adaptability, flexible transfer and the like, significantly improves the support safety and economy of ship sub-assembly construction.

The invention discloses an information sharing method and device, electronic equipment and a readable storage medium, and belongs to the field of information processing. The method comprises the following steps: displaying a running interface of a first application program and a running interface of a second application program; receiving a first input for target information; in response to the first input, sharing the target information through the first application program and / or the second application program; wherein the first application program and the second application program are both installed in the first electronic equipment, or the first application program is installed in the first electronic equipment, and the second application program is installed in the second electronic equipment.

The invention provides a call library system and method based on package management in a PLC compiler, and the system comprises a system library module which is internally provided with a library function, and when a user quotes the library function, a PLC system copies a library package of the function to a project directory, carries out the distribution of a system library, and provides a bottom layer support for a user library; and the user library module realizes functions according to an interface provided by the system library, a user defines a library function and writes a program, and after successful compiling and publishing, other users import and use the user library module. According to the method, the organization structure of the call library file is optimized, and a reasonable organization mode is provided for the call library with various implementation modes, so that the optimal compiling effect is achieved, and the optimization of the efficiency during operation is realized.

The invention provides a lightweight function operation method and system oriented to a server perception-free computing scene. The method comprises the following steps: providing a communication primitive for rapid cold start and high-performance intermediate data transmission of an isolated environment; for a workflow scene without perceptual function calculation of a server, providing a novel software stack architecture during operation; a function and a bottom layer on which the function depends during operation are all deployed in the same CPU privilege level and address space for cold start operation; a library operating system of workflow granularity is used for providing bottom layer runtime service for functions, and meanwhile, a memory security language is used for providing memory isolation and sharing; and realizing an on-demand loading mechanism for the library operating system. The technical problems of slow cold start in an isolation environment, poor intermediate data transmission performance, large cold start range, high cost and poor memory isolation and sharing flexibility are solved.

This invention proposes a blockchain-based access control method for mobile edge-cloud collaboration. The steps are as follows: initializing protocol parameters within the mobile edge network domain; generating the master key and public key of the edge-cloud collaboration system; generating public / private key pairs for the cloud server, edge server, and terminal members; terminal members register their identities, obtain attribute permission parameters, and write them into the blockchain; after successful registration, resource providers share data and set attribute sets and access control policies for accessing the resource; resource visitors access resources within the domain; if the required resource is not found within the domain, the visitor requests a signature from the local edge server and obtains the signature to access the resource across domains. This invention employs hidden attribute authentication technology, ensuring that attributes are not leaked during transmission, thus more effectively and securely protecting personal privacy information. Simultaneously, the protocol, combined with blockchain technology, ensures resistance to collusion attacks, making access control more flexible, efficient, and practical.

The invention discloses a wearable device data processing method based on cloud computing, and the method comprises the steps: a data owner defines a data access strategy, encrypts the data of a wearable device through employing a variant Paillier homomorphic encryption public key, and transmits the data to a service provider; the service provider receives a data aggregation request from the data requester and executes corresponding homomorphic operation according to the request type to aggregate the encrypted data; performing mask processing on the aggregation result, and sending the masked aggregation data to a calculation party; the calculation party uses the strong decryption key to decrypt the mask data, performs calculation processing on the data, re-encrypts the data and sends the data back to the service provider; the service provider carries out mask removal processing on the mask data and sends the aggregated data after mask removal to the data requester; and the data requester decrypts the aggregated data by using the attribute-based encryption private key of the data requester according to an access policy defined by the data owner. According to the method, the privacy of the user can be protected, and flexible data aggregation and sharing can be supported.

The invention relates to the technical field of multi-core DSP application software development, in particular to a multi-core DSP inter-core data sharing method based on a shared memory, which comprises the following steps: a sending core writes shared data into a storage address in a storage address field agreed by the shared memory; the sending core updates the log data of the storage address of the shared data; receiving core loop check log data; the receiving core reads the shared data. According to the method, by following the memory address allocation of the Cache Line, the consistency of the multi-core cache is met; and system abnormity and performance reduction caused by inter-core data asynchronization and inter-core memory access blockage are prevented, so that the signal processing process is efficient, stable and reliable.
