Abstract:
PURPOSE: A device and method for a small amount payment accounting through an interlock with an advanced information communication processing system is provided to prevent an outflow of credit information by executing a small amount payment using a telephone network and to enable a seller to reduce an additional cost by withdrawing a commodity price through a communication network businessman. CONSTITUTION: A small amount payment service is supplied through an interlock with an AICPS(Advanced Information Communication Processing System) in an environment for supplying an electronic payment service. An AICPS telephone micro billing broker(23) is mounted in the AICPS, processes commodity data of a subscriber of a telephone network or an ISDN(Integrated Service Digital Network), and charges a server function in a small amount payment accounting. An AICPS telephone micro billing agent(25) is mounted in a server of an information provider based on a shopping mall(24) and operated, connects to the subscriber, requests to process a purchase data to the AICPS telephone micro billing broker(23), and charges a client function in the small amount payment accounting. The AICPS telephone micro billing broker(23) is connected to a PSTN(Public Switched Telephone Network) through a modem of the subscriber and recognizes a telephone number of the subscriber.

Abstract:
The present invention relates to a method for managing a location of operating device in a plant factory and an apparatus thereof. The method for managing a location of operating devices in a plant factory includes registering, in a sensor network, a plurality of operating devices and sensors installed at a plant factory; generating sensor IDs of the operating devices and sensors registered in the sensor network; and registering location information of the operating devices and the sensors based on the generated sensor IDs.

PURPOSE: A wireless sensor network system and a communication method of the same are provided to effectively respond abnormal situations by co-existing a zigbee-based wireless sensor network and a wireless local area network(LAN) system. CONSTITUTION: Sensor networks(11, 12, 13) include a plurality of sensor nodes. Local servers(21, 22, 23) function as gateways between the sensor networks and a backbone network and transmit data. The overlaying managing parts of the local servers generate wireless LAN overlay networks. Data transmitted from the sensor nodes are processed based on the wireless LAN overlay networks. A data processing process includes the following: the sensor nodes receive a response message containing an address allocated from a wireless LAN system; and the sensor nodes transmit and receive data through wireless LAN overlay network.
Abstract:
PURPOSE: A sensor node including a general-purpose interface port with a plug and play, sensor board including a general-purpose interface port with a sensor device driver, general-purpose interface port and each method thereof are provided to enable a control unit to automatically recognize and control a sensor unit through a universal interface port. CONSTITUTION: A universal interface port(240) offers an interface with a sensor board. The universal interface port downloads a sensor device driver from a connected sensor board. A controller(210) controls the sensor board by using the downloaded sensor device driver. The controller processes sensing data which is generated by a senor included in the sensor board. The universal interface port download a sensor device driver which is related with at least one among SPI(Serial Peripheral Interface), I2C(Inter-Integrated Circuit), ADC(Analog to Digital Converter), Interrupt, and frequency.
