Abstract:
A fallen fruit collecting apparatus comprises: a global positioning system which calculates current position information by receiving position information from a satellite; a database which stores map information and fruit position information; a central processing part which determines a moving path by receiving information from the global positioning system and the database; an equipment control part which controls moving equipment and collecting equipment according to the command of the central processing part; and an image control part which receives and processes an image according to the command of the central processing part, wherein the central processing part judges the existence of fallen fruit by receiving the image from the image control part, and the equipment control part controls the moving equipment to move along the moving path and controls the collecting equipment to collect the fallen fruit.
Abstract:
PURPOSE: A method for switching on and off a security lamp in a security lamp system is provided to control the on and off of the security lamp according to illumination around a relay. CONSTITUTION: A surrounding illumination is sensed by using an embedded illumination sensor(S310). The sensed illumination is compared with a preset reference value(S320). A security lamp on command or a security lamp off command is transmitted to a security lamp switch(S330,S360).
Abstract:
PURPOSE: An apparatus and method of displaying a multi-path for an RF(Radio Frequency) routing unit are provided to confirm an RSSI(Received Signal Strength Indicator) value of a corresponding RF terminal, the number of RF terminals which enables the communication with a sync node, and the number of RF terminals which enables communication in the communication distance of 1 hop based on a response request message. CONSTITUTION: An RF terminal sends a response request message to all other terminals and sync nodes within the communication distance of 1 hop based on a broadcasting command(S20). The RF terminal receives a response message from the adjacent RF terminals(S30), and analyzes the response message(S40). The RF terminals generates the display information(S50).
Abstract:
본 발명은 UART 기반의 RF 통신장치 및 방법에 관한 것으로, RF 통신부를 복수개 구비하고, 각 RF 통신부에서 서로 다른 주파수 대역을 이용하여 신호를 송수신함으로써, 하나의 송신 신호에 대해 서로 다른 주파수 대역으로 신호를 전송하고, 서로 다른 주파수 대역으로부터 동일 데이터를 수신하여 무결한 데이터를 처리하도록 한다. 본 발명에 따르면, RF 환경을 사용하는 센서 네트워크 또는 무선환경 통신망에서 무결한 데이터를 무선환경으로 전송해야 할 경우 데이터의 깨어짐 없이 비교적 깨끗하게 데이터를 전송할 수 있는 이점이 있다. 특히, UART 방식으로 통신을 수행하는 RF 통신칩에 대해서 송신의 경우는 추가적인 소프트웨어 동작 없이 이중으로 데이터를 보낼 수 있는 효과가 있다.
Abstract:
PURPOSE: A guard lamp for transmitting an accident alarm, providing a vehicle parking guide broadcast, and performing an emergency call-out vehicle guide function are provided to rapidly evacuate residents by transmitting a warning call for informing an accident. CONSTITUTION: A guard lamp(100) includes a network connection unit, a speaker drive unit, a warning lamp drive unit, and a control unit. The network connection unit is connected to a guard lamp management server(200). The speaker drive unit transmits an accident alarm through a speaker and provides a vehicle parking guide broadcast. A warning lamp drive unit drives a warning lamp for guiding an emergency vehicle to an accident spot. The control unit controls operations of the speaker driving unit and the warning lamp drive unit according to a control command of the guard lamp management server.
Abstract:
PURPOSE: The train approach alarm device and method. Carrying possibles. The train approach is sensed and the train taking shelter hour is secured enough. CONSTITUTION: The train entry alarm device is composed of the first terminal(100), and second terminal(200). For in the first terminal, the track worker, carrying possibles. It grasps the location information and current location of the train and the first terminal calculates the expected time of arrival of the train. The second terminal informs distance and the calculated expected time of arrival to operator.
Abstract:
PURPOSE: A terminal for vehicles and a method for operation thereof, and a server for providing information and method thereof are provided to supply accurate traffic information in real time by using a vehicle driving on a fixed route. CONSTITUTION: A receiver(210) receives a plurality of traffic signals. A plurality of traffic signal information comprises the identifier information and GPS information of each traffic signal. A GPS receiver(220) receives the GPS information of the terminal for the vehicles. A calculation unit(230) calculates a waiting time at an intersection and the operation time of the intersection. A transmitter-receiver(240) transmits standby time and operation time of the intersection to an information providing server.
Abstract:
PURPOSE: A node updating method based on a database and a target node operating method thereof are provided to update an image of a sensor node by communicating only delta information consisting of difference between a present execution image and an image to update of the sensor node. CONSTITUTION: A database storing a node identifier and an execution image about each node is constructed. The execution image of a target node from the database is extracted by using an identifier of the target node(S330). The similarity of data between the execution image and an updating image is compared with reference to an address field. The data includes a record of the updating image which is not similar. Delta information is generated(S350).
