The invention proposes a handheld terminal system for an urban operation and management system, which is based on the operation platform of the urban operation and management system. The functions of the handheld terminal comprises: the function of information inquiring, the function of setting a control strategy, the function of pushing warnings, the function of GIS map positioning, the function of work order sending, the function of equipment management, and etc. The control strategy part, as the core content of the invention, is able to set a real-time and planned control strategy; and through the setting of the control mode, the light switching time, the light regulation value, the executing cycle, and etc. of the strategy, it is possible to make the urban illumination operation and management intelligent and automatic, and to conserve energy to the largest extent. The other important function of work order receiving is able to know about the detailed information of an arising fault instantly so that proper rescue measures could be taken in the first time and that the responding speed for management and emergency services can be increased. With the invention, it is possible to increase the levels for urban management and services at high efficiency and to stride forward for the goal of intelligent urban operation and management.

Mobile application system for urban illumination operation and management

The present invention is to provide a system and a method for maintaining a lighting device, which determines whether to occur deterioration in function and a failure in a lighting device to notify the same to a user, and improves maintenance through an A/S application and management of the lighting device. To this end, the system of the present invention comprises: a lighting unit for analyzing an operation state and light quantity information on a light source unit to determine whether to have abnormality, transmitting failure occurrence information and A/S acceptance request information to a predetermined user terminal when the abnormality of the light source unit is sensed, and transmitting A/S application information to a manufacturer server when A/S acceptance request approval information is input by the user terminal; a gateway for transmitting and receiving data between the lighting unit, the user terminal, and the manufacturer server using an arbitrary communication format; a user terminal for displaying the failure occurrence information and the A/S acceptance request information transmitted by the lighting unit, and receiving the A/S acceptance request approval information from a user to transmit the same to the lighting unit; and a manufacturer server for receiving and accepting A/S application information transmitted by the lighting unit, and transmitting an A/S acceptance result to the lighting unit. Therefore, the system of the present invention can determine whether to occur deterioration in function and a failure in a lighting device to notify the same to a user, and rapidly and accurately provides maintenance through an A/S application and management of the lighting device, which is difficult to be managed by the user.

System and method for maintaining lighting device

Disclosed are a power saving support apparatus of a radio repeater and a support method therefor. The power saving support apparatus of a radio repeater according to the present invention comprises: an information receiving unit for receiving information about an adjacent radio repeater from each of peripheral radio repeaters; a group formation unit for forming a group of radio repeaters on the basis of the information on each radio repeater received by the information receiving unit; a leader setting unit for setting a leader in the group of radio repeaters formed by the group formation unit; and a mode providing unit for providing a power saving mode to radio repeaters, other than a radio repeater set as a leader by the leader setting unit, in the group of radio repeaters formed by the group formation unit.

Power saving support apparatus of radio repeater and support method therefor

PURPOSE: A system and method for inspecting and managing a security light or a street light are provided to transmit information about the position of the defective security light or street light to the smart phone of a manager, thereby easily inspecting the security light or the street light. CONSTITUTION: A system for inspecting and managing a security light or a street light includes a repeater (130), a management server (110), and the smart phone (120) of a manager. The repeater automatically detects the inspection condition of at least one of the security light or the street light. The repeater transmits inspection data outside through a key communications network. The repeater requires the management server for condition inspection. The management server receives a civil appeal about defects through the transmission of information about the position of the smart phone of a civil petitioner. The smart phone of the manager informs the management server or the smart phone of the civil petitioner of the completion of the inspection. [Reference numerals] (110) Management server; (120) Smart phone; (AA) Network

Guard-lamp or street-lamp management system and the method

PURPOSE: A guard lamp wireless network structure and a control method thereof are provided to actively cope with surrounding environment changes. CONSTITUTION: A relay node(100) transmits control signal information to a plurality of controller nodes(200). The relay node receives monitoring information of a guard lamp from the controller nodes. The relay node transmits the monitoring information to a central control center. The controller nodes receive the control signal information from the relay node. The controller nodes control the guard lamp.
