The wireless sensor network node of the utility model has a plurality of wireless radio frequency modules, and can communicate with a plurality of nodes or computers simultaneously. A plurality of wireless radio frequency modules of the wireless sensor network node of the utility model can work simultaneously, the simulation of a plurality of nodes on a signal node and the simulation of the communications among a plurality of nodes or between a plurality of nodes and computers are realized, thus creating a condition for the research of large-scale wireless network node.
Description
Technical field
The utility model relates to wireless sensor network, particularly the node of wireless sensor network.
Background technology
Characteristics such as environment detail perception that wireless sensor network is powerful and arrangement convenience, extended capability are strong make it all obtain in the industry-by-industry field paying close attention to widely.
Wireless sensor network generally comprises a plurality of transducers, a plurality of wireless sensor network node, has the wireless network card computer; The corresponding wireless sensor network node of transducer, each transducer carries out communication by wireless network card and other wireless sensor network node of each self-corresponding wireless sensor network node and computer.
In the existing wireless sensor network, for improving the scale of wireless sensor network, make full use of limited frequency band resource, people adopt methods such as frequency division is multiplexing, time-sharing multiplex to realize a plurality of network node controls.As adopt in the wireless sensor network of wireless radio frequency modules of 2.4GHz, adopt frequency division the operating frequency section can be divided into 16, that is: wireless sensor network allows 16 network nodes to carry out communication simultaneously at most.The method of employing time-sharing multiplex is stipulated the time period of each network node communication etc.
Existing wireless sensor network node comprises processor, sensor interface, a wireless radio frequency modules; Processor is connected by control line, holding wire with sensor interface, and processor is connected by bus mode with wireless radio frequency modules.
But above-mentioned wireless radio frequency modules is divided into the radio-frequency module of fixed frequency and the radio-frequency module of automatic frequency-hopping.But but the radio-frequency module automatic frequency-hopping of automatic frequency-hopping selects idle frequency band to carry out communication.
The defective of existing wireless sensor network node is: wireless sensor network node at one time can only with a node or computer communication, cause the limited operating frequency section resource and the waste of wireless sensor network node.In addition, though under the network work state, the most time free time, resource utilization is low, to under the actual application environment being necessary requirement, but in some technical field, as in the wireless sensor network research field, particularly when the massive wireless sensor node is tested, will on experimental cost and space, cause unnecessary waste.The requirement of wireless sensor networks is extensive, how large-scale network node being managed is the direction that people study, and existing wireless sensor network node costs an arm and a leg, and environment that can't an extensive layout sensor network nodes of real simulation brings difficulty for research in this respect.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of wireless sensor network node is provided, this wireless sensor network node at one time can with a plurality of nodes or computer communication.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of wireless sensor network node, it comprises processor, wireless radio frequency modules; Processor is connected by bus with wireless radio frequency modules; Wireless radio frequency modules quantity is more than two.
In the such scheme, but wireless radio frequency modules is the radio-frequency module of automatic frequency-hopping.
Have a plurality of wireless radio frequency modules on the utility model wireless sensor network node, at one time can with a plurality of nodes or computer communication.
But the wireless radio frequency modules on the utility model wireless sensor network node adopts the radio-frequency module of automatic frequency-hopping, can utilize the frequency band resource of network more fully.
The utility model wireless sensor network node, can work simultaneously by a plurality of radio-frequency modules, on individual node, realize simulating a plurality of nodes, simulate between a plurality of nodes or the communication between a plurality of node and the computer, for condition has been created in the research of large-scale wireless network node.
