The present invention utilizes RFID technique, is made up of an expelling plate 1 and a dash receiver 4, and adopt Low-power Technology, expelling plate 1 is by user operation, and user can operate user's timing switch circuit 8 and determine that dash receiver is the power-on time of node module 7.
Open the power supply of expelling plate 11 user after, expelling plate 1 sends data according to the transmitting antenna 2 that is arranged through of user to the reception antenna 3 of dash receiver, dash receiver antenna 3 receives the data that expelling plate antenna 2 is launched, pass data to the microcontroller 13 of dash receiver, first microcontroller 13 judges that the whether specific expelling plate of these data launches 1 data sent, if perform the data command received, can not perform if not microcontroller 13.
User operation timing circuit 8 can set timing, this timing is different according to node module, the different time periods can be set, user arranges the time of timing as required, such as arrange one hour, so the microcontroller 9 of expelling plate 1 just can monitor the timing that user is arranged, and microcontroller 9 just launches this data to transmitter module, sends data through transmitting antenna 2.
Reception antenna 3 receives data, be sent to the microcontroller 13 of dash receiver, microcontroller 13 by analysis, first the data that the transmitting terminal of whether this system is launched are determined, if so, microcontroller breaking dormancy state, continues to perform instruction below, if not, microcontroller is in resting state.After breaking dormancy state, perform the timing that transmitting terminal sends, start timing, and switched on power by switching circuit 14, for node module work.After microcontroller 13 timing terminates, such as, reach one hour, at once closing switch circuit 14, for the power-off of node module 7, node module 7 loses power supply and quits work, and reaches the effect of saving electric energy.
The timing switch circuit 8 of this expelling plate is a kind of switching circuit of self-locking of many gears, and user can determine the time of timing as required.Different according to node module, the switch of this many gears is also different, and the timing range therefore arranged is actually the needs according to node module, arrange gear number and the setting of timing section.
Timing function is a bright spot in this invention, user operation timing switch circuit 8 can be useful among various application, such as, after long timing, can operation transformation be short timer again, if the time of the short timer deficiency of time timing at this moment reset, to timing be continued, after reaching short time timing, then closed node power supply; If the short timer time reset has met or exceeded the time of timing, by the power supply of closed node module immediately.The timing that the time of and for example retiming is greater than original setting, so will continue timing, after reaching the timing set below, then the power supply of closed node module.Here it should be noted that if reset timing, the time of timing originally can not reset, and will add up timing, thus reaches the consistency of user's setting and timing.
This invention have employed the RFID module of low-power consumption, utilizes the wireless transmission function of RFID module, realizes the object of node module power saving.Decrease the cost of exploitation in addition in force, saved the time of exploitation, made this circuits shortens of the exploitation construction cycle.Adopt the microcontroller of low-power consumption, this microcontroller has dormancy and the function waken up, it power consumption very low, when waking up, the electric current of only tens milliamperes, only has the electric current of tens microamperes when dormancy.The time of microcontroller dormancy is far longer than the time of waking up in circuit, and therefore, the power consumption of microcontroller and RFID module is low-down.
Further describe advantage of the present invention below by the embodiment of the present invention and comparative example two groups test, the present invention and comparative example often group arrange 7 sensor nodes, aggregation node, a media gateway A8 composition; When Software for Design becomes to click the respective sensor icon on A8 screen, transducer wakes up from sleep, starts image data and by the transfer of data that collects to A8, clicks to terminate that time delay 5s is laggard to be entered to sleep.
In experiment, a kind of timing of the present invention low-power consumption energy saver embodiment is PIND1003 scheme, and employ an expelling plate 1,7 dash receivers 4, dash receiver 4 connects acquisition module respectively; Expelling plate 1 have employed Micro Energy Lose chip, use the Leah powered battery of 3.6 volts, a joint, dash receiver 4 have employed Micro Energy Lose chip equally, the Leah battery of 3.6 volts, a joint is used to power for receiver module and microcontroller, the 5# south of 1.5 volts, two joint is used to inspire confidence in serial battery for switching circuit 14 and power output circuit 16, to provide the power supply of Internet of Things module.As shown in Figure 5.
