Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Internet of things node is the basic functional units of wireless sensor network, and as shown in Figure 1, its structure mainly comprises sensor assembly, micro controller module, four parts such as radio-frequency module and solar-electricity source module.Wherein, sensor assembly is responsible for gathering the information of monitored area and is finished data transaction, and the information of collection can comprise temperature, humidity, luminous intensity, acceleration and atmospheric pressure etc.; Micro controller module is responsible for controlling processing operation, Routing Protocol, synchronously location, power managed and the task management etc. of whole node.Radio-frequency module is responsible for carrying out radio communication with other nodes or aggregation node, exchange control message and transmitting-receiving image data; The solar-electricity source module provides node to move needed energy, the solar-electricity source module comprises solar cell, control circuit and rechargeable battery, solar cell is connected with described rechargeable battery by the control circuit that is used for the control charging and discharging, and rechargeable battery is given respectively sensor assembly, radio-frequency module and micro controller module power supply.
As shown in Figure 2, control circuit control rechargeable battery charging and discharging, the solar-electricity source module can carry out real time charging in the environment that has light source to exist, guarantee that Internet of things node has sufficient power supply, do not need to charge frequently and avoid because power supply exhausts and interruption of work the on-the-spot trouble with changing battery of must sending someone; Do not having light source in particular cases, rechargeable battery is kept the Internet of things node normal operation.
In Fig. 3, Fig. 4 and embodiment shown in Figure 5, that the utility model adopts is 16 single-chip microcomputer MSP430 with super low-power consumption characteristics, and built-in 8051 single-chip microcomputers of MSP430 are as the core of processing module.Its static current of lcd has reached the mA level.Have powerful operational capability and abundant peripheral hardware.Peripheral hardware is DLL (dynamic link library) preferably, can be so that this Internet of things node upgrade internal firmware at any time, and practicality is got up more flexible.
Radio frequency the utility model is selected the CC2430 chip of 0.18 μ m CMOS explained hereafter, only need peripheral circuit seldom, and the original paper cost of selecting is low, can support the structure of quick, cheap ZigBee node.The sleep pattern of CC2430 and and mode of operation between ultrashort activation change-over time so that this RF-IC becomes the ideal solution of using for the overlength battery.
Select this radio frequency chip can be so that Internet of things node has super low-power consumption, high sensitivity, outstanding antinoise and antijamming capability.
For emulation, debugging convenient and compunication and chip, the utility model has designed two interface road USART(Universal Synchronous/Asynchronous Receiver/Transmitter at node circuit, universal synchronous/asynchronous serial reception/transmitter) interface and JTAG(Joint Test Action Group, joint test behavior tissue) interface.The USART interface is used for synchronous/asynchronous serial communication, the emulation of jtag interface chip, debugging (DEBUG).
Current, USB interface is used widely, for USART is connected more easily with computer, the design has also designed " USB turns serial ports (USB-Serial) " data wire, this data wire can make usb signal and rs 232 serial interface signal mutually change, thereby node module can be connected more easily with computer.
Sensor assembly is used for the required information of acquisition node, if serviceability temperature transducer only can adopt the built-in temperature sensor of CC2430, if require more high accuracy, and can be at the higher temperature sensor of choice accuracy, such as adopting digital hygro sensor SHT1x.
