Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, as shown in Figure 1, Figure 2 and Figure 3, provide a kind of wireless sensor network node system.
The wireless sensor network node system of the present embodiment, main improved design considerations has comprised:
Mini USB interface: use this port, node can be connected to the USB port of server.Have a typical USB cable of four wires: two for power supply and two for transfer of data.Two wires are connected to battery charger (MAX1551), and in the time of USB power failure, system can automatically switch to rechargeable battery.
Selector switch: the data wire of Mini USB interface, by selector switch, is then connected to a USB serialization controller (FT232RL).Its effect is, in the time that node is in running order, can, by data wire ground connection, so that PC can not detect the existence of this device, but provide power supply simultaneously.In fact, this switch is that 3 way switch switch between mode of operation, PC pattern and programming mode.Under mode of operation, data wire is all ground connection.Under programming mode, by the parameter of configuration MSP430, the data that port is received are regarded as new firmware.Under PC pattern, host node, as a peripheral hardware of PC, carries out transfer of data with PC by USB.This pattern is very useful, host node can be used as to gateway and base station is used (control computer), and it is equivalent to the network interface card that computer leads to wireless sensor network.
Expansion interface: expansion interface is for being connected between host node and vice-node.Although expansion interface is the interface that has adopted a USB pattern, itself do not have USB master control ability.In this experimental system, we are only design and the manufacturings that facilitates node with the interface of this pattern.It is connected with vice-node by RS232 serial signal.
The design of vice-node and host node is basic identical, can think that vice-node is a host node of removing radio-frequency module.The same with master reference node, secondary sensor node also possesses 3 mode selector switch, in order to switch the mode of operation of USB interface.In addition, it also has an outward appearance as the socket of USB female, for the more secondary sensor node of cascade.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
