The invention relates to the field of the Internet of Things, system development and distributed deployment, and specifically discloses a highly customized distributed platform development method, comprising a cloud server, a client server and a client terminal, wherein the development of a platform system is completed by establishing a universal template, extracting a common function, developinga cloud service system, performing customized development, and performing distributed deployment, and the numerous customized promotion of the platform is finally achieved through the customized development and distributed deployment of different customers. According to the highly customized distributed platform development method disclosed by the invention, by developing the template and providing the common function, the platform system development and customization of a large number of similar institutions becomes more efficient and faster, so that the purchase and development costs are reduced, the hardware requirements for a deployment system are reduced, the local operation and maintenance pressure is reduced, and a part of local maintenance work can also be performed by an upper-level cloud server, so that the system use effect of a user is improved. Meanwhile, important information and data are locally privatized, thereby improving the information security of the cloud servicesystem.
