Abstract
Systematic unified coding is carried out on all nodes in a system in a wireless micro-power routing-free automatic remote communication technology of fixed nodes, and directionality parameters and distance parameters are carried in coding. In the system, at least three nodes with known positions are pre-arranged, and the nodes obtained through location computation are taken as known points, the position of each node of the system is located one by one, a distance between each node and a fixed original point is taken as a radius of a sphere, and longitude and latitude of the nodes are taken as directions to mark, so that system coding of all nodes in the system is determined. The method belongs to the field of wireless communication. Figures in abstract indicate communication transfer and relay determination, and all nodes in a columnar region in a certain radius of a target node are taken as a communication participation group to participate in signal forwarding waiting and forwarding.
Description
Technical field
The present invention a kind ofly carries out Unified coding and realizes the method for communication protocol each stationary nodes in full stationary nodes system.Belong to wireless communication field.
Background technology
In needing system in " a kind of stationary nodes wireless micro-power is without the route automatic remote transmission communication technology ", all nodes carry out systematic unity coding, and realize communications by this coding.
Summary of the invention
In needing system in " a kind of stationary nodes wireless micro-power is without the route automatic remote transmission communication technology ", all nodes carry out systematic unity coding, and are with directivity parameter and distance parameter in coding.In system, we can arrange the node that is no less than three known location in advance, and using location Calculation node out also as known point, one by one the each node of system is carried out to location, position, distance taking node to fixed origin is the radius of a ball, taking the longitude and latitude of node as hand designations, determine the system coding of all nodes in system with this.
On communication is transmitted and is determined with relaying, participate in family using all nodes in destination node certain distance radius cylindrical region as communication, the forwarding that participates in signal is waited for and is forwarded.
Fig. 1 is that fixed general-purpose system coding is determined schematic diagram with the participation family that communicates by letter.Suppose to have signal will transmit D4 point from O point, communication participates in family and leads to all nodes in the cylindrical region that O orders at D4 point taking r as radius.
Fig. 2 is the schematic diagram of system being simplified with respect to velocity of electromagnetic wave.System node can plane polar coordinates mode mark coding.
Fig. 3 participates in the again simplification communication scheme of family's node with respect to velocity of electromagnetic wave to the communication in Fig. 2.
Fig. 4 is system node location schematic diagram.When positioning calculating formula to 1 region each point, 2,3, the 4 whole power down in region, system is by the calculating that positions a little one by one in known O, 1,1 pair of 1st district.Carry out the node in other each districts also to position with same method again, the each node of system is just located by region by direction like this, can carry out Unified coding.
Fig. 5 is at water, electricity, gas, heating power table radio meter register actual condition and the sense of building cigarette, Disaster prevention and alarm actual condition schematic diagram.Because all nodes are all in the region being fixed on regularly separately, so just can directly carry out taking direction and apart from removing this link of location Calculation from as basic coding.
Claims (4)
1. arrange that for full stationary nodes system is artificial being no less than three nodes positions calculating as known point to other each nodes of system.
2. based on claim 1, system is carried out taking longitude and latitude as direction coordinate to the coding method taking the node radius of a ball of living in as range coding reference.
3. based on claim 2, can obtain the polar coordinates system coding method of almost plane to system simplification.
4. based on claim 1 and 3, for checking meter as water, electricity, gas, heating power and the actual condition such as the sense of building wireless smoke, Disaster prevention and alarm, can directly be reduced to fixed-direction with apart from assembly coding.
