Embodiment
As shown in Figure 1, the present invention is made up of radio-frequency module, key-press module, display module, decoder module, signaling module and control module; Key-press module is connected control module respectively with decoder module, and control module connects display module and signaling module respectively, control module and radio-frequency module interconnection, control module built-in FLASH.
At first, learning type infrared remote-controller is installed over against air-conditioning, system powers on, the wait initialization is finished, the icon of seeing infrared remote control on gateway lights, and the expression telepilot has added wireless sensor network, and this part work is worked in coordination with by radio-frequency module and control module and finished.
The telepilot coding of learning objective electrical equipment, this part work are worked in coordination with by decoder module and control module and are finished.With the telepilot of target electric appliance (being called for short the target remote control) and learning type infrared remote-controller over against, the operator scheme button makes learning-oriented remote control enter mode of learning.Successively press the function button of learning-oriented remote control and the function button of target remote control, just can finish the process of learning objective telepilot coding, after each coding study was finished, the learning state pilot lamp of correspondence can be pointed out whether learning success of user's present encoding.The coding of successfully acquiring deposits among the FLASH, in case lose after the power down.After having learnt all keypress functions, press mode key once more, system promptly withdraws from learns the sign indicating number state, then enters the process that adds wireless sensor network again.
After learning-oriented remote control adds wireless sensor network again, promptly enter dormant state.It just can receive from the gateway or the steering order of user mobile phone (be actually mobile phone and give learning-oriented remote control by gateway forwards) as a control device in the network, thereby realizes the Long-distance Control to target electric appliance.Control module regularly wakes up automatically, and the back of waking up receives the steering order that radio sensing network transmits, and by control module the instruction that receives is resolved, and controls the signaling module then target electric appliance is carried out signaling control.
In addition, learning-oriented remote control also can be worked as normal remote control and use after being added network.After learning-oriented remote control networked successfully, the most of the time was in dormant state, and manually button can directly wake it up, handles manual key information by control module, controls the signaling module then target electric appliance is carried out signaling control.Therefore, available learning-oriented remote control replaces original-pack telepilot to use.
The radio-frequency module frequency of operation is 433MHz, 255 of channel numbers, and message transmission rate and adjustable power, peak transfer rate 500kbps, maximum transmission power 10dBm, the wireless transmission distance maximum at the spaciousness place can arrive 300m.
The omnidirectional antenna of the employing vertical polarization directions of radio-frequency module, maximum antenna gain 2.5dBi, maximum standing-wave ratio (SWR) 2.0.
Whole system operating voltage 3.3V, the AC/DC that adopts big 12V provide system required 3.3V as input after the DC/DC module on the circuit board is changeed.Working current during dormant state is less than 1mA, and maximum operating currenbt is less than 50mA.
Software workflow:
As shown in Figure 2, at first system powers on, and finishes some initial configuration work, as the emissive power of radio-frequency module, transfer rate etc.
After system initialization was finished, study remote controller just began to add wireless sensor network.In case successfully add network, control module and radio-frequency module enter dormant state, have only that built-in timer interrupts this moment, the reception message interrupts of radio-frequency module, and manual button interrupt waking control module up.
If control module is waken up, at first judge and interrupt the source, if radio-frequency module receives message interrupts, then the network information is resolved, control signaling module controls target electric appliance then; If timer interrupts, show it is frame arrival lock in time, control module wakes radio-frequency module up, by radio-frequency module and wireless network exchange message; If manually button interrupts, show the manual remote controllers of user, learning-oriented remote control enters manual control model.After entering manual control model, judge at first whether button is the mode of learning key, if the mode of learning key, the study of encoding of control module control decoder module, if the general function button, control module is controlled signaling module signaling.
After handling interrupting information, control module and radio-frequency module enter dormant state again, wait for the next arrival of interrupting.
The present invention has adopted intelligentized decoding process, need not to know in advance the coded format by learning object, so long as the infrared coding of 38KHZ almost can both be learnt.Its decoding process highly versatile, be decoded into the power height.This device is easy to use, both can manually directly control, and can carry out Long-distance Control by mobile phone or gateway again.Adopt a series of low-power consumption and integrated device, apparatus of the present invention have volume characteristics little, low in energy consumption.Adopt wireless radiofrequency transmission technology and AC/DC power supply, make layings, safeguard simply and cost low.The device working stability is reliable, and the continuous firing ability is strong.The present invention has a wide range of applications in the household electrical appliance Long-distance Control.
