The invention discloses an urban environment quantized data organization method represented by vectors and grid hybrids, which includes that (1) construct a three-dimensional urban model; (2) the characteristic substances in the three-dimensional urban model is divided into two types including district environment and indoor architecture environment; for the district environment, precision setting is firstly made and then perform the division of map-layer, and present each divided map layer in a way of grid; for the indoor architecture environment, firstly perform the entity division on a semantic level and then perform the division of map-layer, and the map layer is presented in a way of vector; (3) map the grid-vector-based data map layers on the XML-based space objects one by one, the simulation application of the upper layer is actuated as the description above, and the characteristic substances act as query units so that the related environment information can conveniently be found out. The invention effectively avoids the drawbacks of using grids to describe the properties of urban environment such as large data amount and low precision, and at the same time expands the traditional two-dimensional description of environment information to the three-dimensional so as to be applied to the interactive simulation of the three-dimensional city.

The present invention relates to an electrical safety diagnosis system and apparatus, which are configured to enable sensed data on user surroundings in a U-city environment, such as electrical safety data for switchboards and distribution boards, and water leakages, faulty outlet connections, etc., to be managed remotely by a server at a U-city integrated information center. In particular, the present invention relates to an electrical safety diagnosis system and apparatus which use a U-city integrated information network to preemptively perform checking and analyzes for potential electrically-induced disasters that can occur in public facilities, stores, buildings, and homes within a U-city, by means of a U-city integrated information center, and prevent electrical fires or shocks at the electrical equipment of switchboards or distribution boards, and dangerous conditions (such as water leakages, abnormal temperatures, gas, and faulty outlet connections) in facilities used by users. The remote electrical safety diagnosis system of the present invention comprises: a digital switchboard including the functions of checking electrical equipment in a switchboard room using a contactless arc sensor and a partial discharge sensor on a power line, to diagnose the safety of the electrical equipment, diagnosing an arc or partial discharge in a detected waveform and storing the diagnosed data, and transmitting the diagnosed data to a higher level server; and a digital distribution board including a main circuit breaker and a partial circuit breaker, for checking an AC voltage or current input through the power line, storing the checked data, and transmitting the diagnosed data to the higher level server.
