Abstract: The present disclosure provides an integrated management and control system for a power plant including a power plant cloud edge vertical architecture system, which includes an inter-plant cloud platform, a plurality of intelligent control platforms, and a plurality of plant-side edge cloud platforms. Each intelligent control platform corresponds to one plant-side edge cloud platform and one power plant that are located in the corresponding power plant. The intelligent control platform is positively interconnected to the corresponding plant-side edge cloud platform via a forward isolation device, and the intelligent control platform is inversely interconnected to the corresponding plant-side edge cloud platform via a network switching device and a reverse isolation device. The plant-side edge cloud platform is bidirectionally interconnected to the inter-plant cloud platform over a private power network. The plant-side edge cloud platform is a reduced capacity private edge cloud system for a power plant.

Abstract: A regular octahedral iron phosphate, a preparation method thereof, a lithium iron phosphate cathode material, and a lithium iron phosphate battery are disclosed. The method for preparing the regular octahedral iron phosphate includes: obtaining a mixed solution A containing a phosphate and a ferrous salt, in which, the mixed solution A is an acidic solution; mixing the mixed solution A with an oxidant, during which, ferrous ions in the mixed solution A are oxidized into ferric ions, whereby obtaining a slurry A; mixing the slurry A with a phosphoric acid solution and enabling reaction under a heating condition, whereby obtaining a slurry B; and subjecting the slurry B to solid-liquid separation treatment, washing treatment, drying treatment, and calcination treatment, whereby obtaining the regular octahedral iron phosphate.

Abstract: A simple net cover device that includes a connecting plate, a cover body and a bottom fixing part. The cover body is set between the connecting plate and the bottom fixing part. The cover body includes the first end part and the second end part. The first end part is embedded into the connecting plate to locate the cover body and the connecting plate. The second end part is fixedly connected to the bottom fixing part. The simple net cover device is characterized by simple processing and assembly, low manufacture cost, not easy to wear in bottom and long life, and can ensure the net cover is supported. The present invention also provides a lamp including the simple net cover device, which can not only be used alone, but also can be strung into a string of lamps to meet the diversified use needs of the users.

Abstract: A simple watertight lamp and string lamp, including: lamp housing set with a mounting groove and two mounting blocks, containing a mounting hole connecting the mounting groove which is used for mounting the luminous module; hanger loop which is back on one side of the mounting groove together with the lamp housing and connects with the lamp housing to form a hanger loop mouth; two watertight covers set with a wire hole and can be dismounted and connected with mounting block, enabling that the watertight cover and the mounting block fit each other to seal the wire which goes through the wire hole; and lampshade which is mounted to the lamp housing in the sealed mounting groove. This realizes relatively independent wires and lamp by virtue of two watertight covers and the lamp housing of a removable structure, improving the mounting and maintenance efficiency of string lamp.
