Abstract:
The present invention relates to a fishing net moving device of cultured species which allows cultured species to actively move as they grow thereby reducing stress according to artificial movement and lowers decline in growth and a disease incidence rate. A fishing net moving device of cultured species comprises: an attracting device installed to move cultured species in the fishing net to a fishing net at the other side; a movement access net installed between the fishing net and the other side fishing net, a movement passage door installed at the center of the movement access net; a measurement unit for measuring a size of the cultured species; and a control device to open the movement passage door if the size of the cultured species is more than a determined value.
Abstract:
PURPOSE: A movable environment controlling apparatus is provided to consider the condition of the plants in a greenhouse and not the work time for obtaining minimum space for controlling the environment of the greenhouse. CONSTITUTION: A controlling node(20) is installed at a ceiling part. A movable part is installed between a ceiling part and a frame(5) for the ceiling of the greenhouse to have a pulley(41) which moves up and down. The controlling part operates the movable part according to the set conditions so that the space for controlling the environment of the greenhouse which is controlled by the controlling node is controlled by moving the ceiling part up and down.

Abstract:
PURPOSE: An apparatus for managing a controlling node, a method for the same, a growing environment sensor network system using the same are provided to reduce the overhead of a data frame by managing data for the controlling node at a separate server. CONSTITUTION: A data analyzing part(31) analyzes data collected from a sensor node. The data analyzing part selects a controlling node containing a controlling device to be controlled. A server accessing part(32) communicates with a managing server(50) saving and managing metadata. A metadata acquiring part(33) acquires the metadata related to the controlling device contained in the selected controlling node.
Abstract:
PURPOSE: An apparatus and a method for managing a slot are provided to manage a slot through the three times of command frame exchange and the primitive exchange of MLME(MAC sublayer management entity) and an upper layer. CONSTITUTION: A node 3 transmits a DSME-GTS(Deterministic And Synchronous Multi-Channel Extension Guaranteed Time Slot) request command for requesting the allocation of a slot to a node 1(S310). The DSME-GTS request command includes the number of a requested slot and information about a current DSME slot allocation bit-map sub block. DSME SAB(Slot Allocation Bitmap), sub block information has a bit-mapped form. The node 1 broadcasts assigned slot information and a DSME-GTS response command, which includes a destination address, to an adjacent node(S320). The assigned slot information includes the DSME SAB sub block information A node 3 broadcasts the slot information assigned to inform an allocation result to the adjacent node and the DSME-GTS notification command including the destination address to the adjacent node(S330).
Abstract:
PURPOSE: A constant amplitude decoding apparatus and method are provided to determine whether vertical direction decoding and horizontal direction decoding are repeatedly executed or not by restoring a constant amplitude multiplexed signal to a two dimension signal. CONSTITUTION: Inverse diffusion and inverse multiplexing module(110) receive data row of constant amplitude. The inverse diffusion and diverse multiplexing module inversely diffuses and multiply the data row of constant amplitude and restores to a two dimension signal. A decoding module(120) executes vertical direction decoding about the two dimension signal. A control module(130) determines whether the vertical direction decoding and horizontal direction decoding are repeatedly executed or not. A bit row information output module outputs a result which is decoded by the decoding module to a bit row.
Abstract:
PURPOSE: A method and a device for synchronous sensor network construction are provided to comprises a sensor network through Power-Beacon which is output-controlled in a sensor node having one radio transceiver. CONSTITUTION: A beacon frame is outputted. The beacon frame controls a coordinator(401) and active period and inactive period of device nodes. The device node is converted to the active period by the beacon frame. The device nodes collect data. The data is received from the coordinator of the first sensor field and relay node coordinator of the second filed. The relay node coordinator shares at least one of the device nodes with the first sensor node.
