Describe principle of work of the present utility model and process below in detail.
That gsm module 3 of the present utility model is used is GSM whole world mobile network.User mobile phone forms communication link by gsm wireless network and gsm module 3, gsm module 3 is by forming communication link between serial communication module 4 and the embedded controller 5, the control output end of embedded controller 5 is connected with interface circuit 7, and interface circuit 7 is connected with the positive signal end of major loop o controller 8.System controlling software is installed in the embedded controller 5.The power input of major loop o controller 8 inserts the 220V civil power, and the first output terminal L and the second output terminal N accept load, and every road seals in current sensor 9 in the electric appliance load loop.
Gsm module feed circuit 1 are gsm module 3 power supplies, embedded controller feed circuit 2 are embedded controller 5 power supplies, gsm module 3 carries out communication by serial communication module 4 and embedded controller 5, system controlling software is responsible for the external coordination of embedded controller 5, embedded controller 5 is given an order to interface circuit 7, after the amplification of interface circuit 7 signals, the positive signal end of dc controling level to major loop o controller 8 is provided, thus the conducting of control major loop o controller 8 with close.Control between system controlling software and the gsm module 3 is undertaken by the AT order.AT order (AT Commands) is at first released by Hayes company, has become the Modem commands language system that all modem manufacturers adopt now.Every order is with letter " AT " beginning.AT heel letter and number shows concrete function.Comprise optocoupler 21 in the interface circuit 7, realize the input of signal, the triode 22 in the interface circuit 7 carries out current signal and amplifies to drive the conducting of major loop o controller 8 and close.
Gsm module 3 is integrated radio frequency unit and baseband processor are operated on four frequency ranges of GSM850/900/1800/1900MHz, support the gsm communication standard; Gsm module 3 comprises SIM card interface, RS232 interface, power interface, startup interface and duty interface.The core of system controlling software is the encoding and decoding that carries out short message.Short message sends the PDU pattern that adopts based on the AT order, not only supports Chinese pattern, also can send English note.Every message can be held 140 English bytes of maximum length or 40 Chinese characters.If there is new note to arrive, then gsm module 3 point out automatically to serial communication module 4, after embedded controller 5 receives signal, sends and reads information order, read note and processing from SIM card after, note is deleted.
The control output end of embedded controller 5 is P1.0-P1.7 and P2.0-P2.7 totally 16 I/O ports.Accordingly, the interface electronic circuit in the interface circuit 7 can be 1-16, and the number of major loop o controller 8 can be 1-16, and each major loop o controller 8 can be embedded into the control of formula controller 5 code identification.The signal output of the control output end of embedded controller 5 is given optocoupler 21 through phase inverter 26 backs, and the model of optocoupler 21 is OPTOISO1.The model of triode 22 can select 9013.Optocoupler 22 is isolated input/output signal, and triode 22 realizes that electric current amplifies.
In order to prevent the consideration of maloperation and security aspect, embedded controller 5 has been preset the cell-phone number that is authorized to mobile phone or security password as the security feature sign indicating number.User mobile phone sends note, after embedded controller 5 has read the note that gsm module 3 receives, check whether the phone number that sends note is the cell-phone number of presetting that is authorized to mobile phone, perhaps check in the content of note whether comprised specific security password, be used for carrying out the discriminating of security feature sign indicating number.
Monitoring power supply wireless controller groundwork process is as follows in real time for this:
The user sends note to gsm module 3 by user mobile phone, after gsm module 3 receives note, prompting serial communication module 4 has new information to arrive, serial communication module 4 prompting embedded controllers 5 carry out serial communication, the content of SIM card (note) reads in the embedded controller 5 by serial communication module 4 in the gsm module 3, system controlling software is resolved the content of note, at first carries out the discriminating of security feature sign indicating number; Distinguish control command then: the one, distinguish the port of embedded controller 5 control output ends, the 2nd, the order request of identification control.Short message content can be compiled as " OpenN " or " CloseN pass ", and wherein N represents the port of 1-16 embedded controller 5 control output ends.System controlling software forms control command after resolving short message content, and control command by the I/O port (P1.0-P1.7) of embedded controller 5 and (P2.0-P2.7) is exported high level or low level, is connected with the interface electronic circuit of separately interface circuit 7.When embedded controller 5 output high level, become low level after anti-phase by phase inverter 26, this moment, embedded controller 5 bore the electric current that recharges of about 15mA; When embedded controller 5 output low levels, become high level after anti-phase by phase inverter 26, high level presents high-impedance state, there is the drive current about 10mA in the input end of optocoupler 21 this moment, optocoupler 21 conductings, the base current of triode 22 is about 1mA, this moment, the collector current of triode 22 was about 100mA, the drive current of major loop o controller 8 is about 100mA, major loop o controller 8 output terminal conductings this moment, civil power 220V is loaded on the electric appliance load, and electric appliance load gets electric work.When therefore this real-time monitoring power supply wireless controller needs turn-on power, embedded controller 5 output low levels; When this real-time monitoring power supply wireless controller needs powered-down, embedded controller 5 output high level.
During embedded controller 5 electrification resets, each I/O port presents high level, and 8 outputs of major loop o controller are in dissengaged positions, can not cause the maloperation phenomenon of load.When 8 conductings of major loop o controller, when the electric appliance load loop had electric current to pass through, current sensor 9 detected size of current, and the signal end of current sensor 9 is connected with embedded controller 5.Embedded controller 5 obtains the real-time current numerical value in the electric appliance load loop of major loop o controller 8 by current sensor 9.User mobile phone can obtain the current situation of load end by gsm module 3 inquiries, and when user mobile phone was inquired about to gsm module 3 requests, embedded controller 5 sent to user mobile phone with electric appliance load current in loop situation through serial communication module 4 and gsm module 3.The user can inquire the actual working state of this real-time monitoring power supply wireless controller in real time when effective control of carrying out power supply, when avoiding system to break down, the user can't obtain the true operation conditions of electrical equipment.
The mode of the utility model power supply control belongs to wireless remote control, and it is low to control cost, and has realized multiple-output electric power control, and high safety meets the Internet of Things future development trend, satisfies the wireless sensing control needs of multichannel household electrical appliance power supply.The utility model can satisfy the controlled in wireless that domestic power supply is opened and closed, thereby realize the wireless remote control of household electrical appliance, the introducing of the real-time monitoring technique of loaded work piece electric current, the security of wireless remote control system and the property monitored have been strengthened, can promote the intellectuality of household electrical appliance to use, comply with the industry trend of Internet of Things Smart Home.
