The invention discloses a full-life-cycle management and control system for metering designing. The system is composed of a management platform, distribution network design software, distribution network cost software and a mobile phone app. The management platform, the distribution network design software, and the distribution network cost software are based on a mobile internet. The operation and usage of the system are extended from a PC terminal to a hand-held terminal like a smart phone or an Ipad as well as to management and uploading of field surveying data. The management platform consists of an external system, a business platform, a development platform, middleware and a system platform. The external system includes planning software. According to the full-life-cycle management and control system, advanced applications of plan designing, engineering cost, project control, and teamwork of the whole process of the primary and secondary project designing of the distribution network for researching and development, designing and construction as well as development of a mobile phone app and a field surveying design terminal can be realized. With the information means, field data collection of the distribution network engineering project is simplified; the executive standards are standardized and unified; the material equipment model selection becomes simple; the reportingworkload is reduced; and the error rate is reduced.
