MESH NETWORK SYSTEM IN ASYMMETRIC WIRELESS OUTPUT ENVIRONMENT

摘要

According to a feature of the present invention, by using a radio frequency in the 900MHz band functioning as a RS (Relay Station) to each other to form a mesh network (MN) and the operation control according to the control signal received through the mesh network (MN) A plurality of end node device units 110; And a signal connection to each end node device unit 110 through the mesh network (MN) and outputting a control signal for driving control of each end node device unit 110 according to an input signal or a programmed item. Station), the master device unit 120; includes, the master device unit 120 outputs a packet (Bd1-pkt) for the uplink updater, each end node device unit 110 is the uplink When the updater packet (Bd1-pkt) is received, the hop value (HOP) is increased to broadcast to the neighboring end node device units 110, and the hop included in the received uplink updater packet (Bd1-pkt) ( A mesh network system is provided in an asymmetric wireless output environment, characterized by updating the uplink table based on HOP), sequence number (SEQ), and received signal strength (RSSI).
