The method disclosed by the invention unifies the data gateway, the demands of different services can be quickly satisfied, and the method hasthe features of being high in security, stable in data, high in concurrence, and flexible and dynamic in configuration.

The invention discloses a lithium ion battery positive electrode material, a lithium ion battery positive pole plate and a lithium ion battery, and relates to the technical field of lithium ion batteries. The lithium ion battery positive electrode material mainly comprises the following constituents based on percent by mass: 97.5-98.5% of positive active substance, 0.3-0.8% of conductive agent and1-2% of binding agent, wherein the positive active substance comprises 10-50wt% of lithium ferric manganese phosphate and 50-90wt% of Ni-Co lithium manganate, the lithium ferric manganese phosphate is LiMn<x>Fe<1-x>PO4, x is more than 0.5 but less than 1, the Ni-Co lithium manganate is Li(NixCoyMnz)O2, the conductive agent comprises graphene, and the graphene accounts for 40-100% of the mass of the conductive agent. By the lithium ion battery positive electrode material, the problem that the energy density and the safety of a traditional lithium battery cannot be compatible is solved. By improving the active substance and the conductive agent in the positive electrode material, the positive electrode composite material compatible with the energy density and the safety, the positive pole plate and the lithium battery are obtained.

The invention relates to the technical field of data processing, in particular to a cloud platform data processing method, which comprises the following steps: S1, performing communication connectionon a data acquisition module arranged on a cloud server and an Internet of Things platform, and performing communication connection on a data processing module arranged on the cloud server and the Internet of Things platform; S2, connecting a data distribution module to the data processing module, and storing the data distribution module on a local disk through respective distribution storage modules; S3, after the storage position of each block file is stored, pre-reading each block file, and executing pre-read data by an execution module and is processed by a processing module; and S4, communicating the service processing module with the Internet of Things platform and the data processing module, transmitting data through the service processing module, and providing a data analysis result. The technical problems that in the prior art, when data are analyzed, the cost is high, and the safety is low are solved, and the stability of the cloud computing service is guaranteed.

The invention provides a service control method and device, and the method comprises the steps: generating an internal unified operation code according to a request parameter carried by a first service request after the first service request transmitted by service request equipment is received; according to an operation command corresponding to the operation code determining a protocol of a service server executing the operation command and generating a second service request corresponding to the protocol so that service request control under different protocols can be centrally managed and then uniformly distributed, and service access among the servers is more efficient; and meanwhile, after the second service request is generated, searching for the service identifier of the target service server according to the operation code. Thus, the service request equipment cannot know the access address of the target service server, and the security problem caused by direct access between theservice request equipment and the service server is relieved. In addition, the service record is generated and displayed on the display equipment, so that the convenience of system maintenance is improved.
