Description

A kind of electric cooker telechirics

Technical field

The present invention relates to a kind of electric cooker telechirics, belong to Smart Home technical field.

Background technology

In prior art, for the Long-distance Control of electric cooker, major way is by connecting WiFi or Bluetooth pairing customer mobile terminal, then user installs APP on mobile terminals and controls, although it is comparatively easy that this mode controls for single electric cooker, but in real life, often there is multiple equipment to connect WiFi in user family simultaneously, and network may be in full load condition (such as user opens download software in computer end before going out and downloads) in family, the mode of therefore carrying out Control on Communication by WiFi often can not meet the requirement of control, and by mode that bluetooth connects, user also cannot Long-distance Control, moreover change the electric cooker with remote control function to realize Long-distance Control, obvious user cost is too high, general user is difficult to accept, on the other hand, adopt the mode of APP, for majority is middle-aged and old, also more difficult at present, a lot of the elderly is still in the situation can dialed reluctantly, send short messages at present, and will install APP smoothly and smooth use, reality does not meet current social present situation.

Summary of the invention

For solving the problems of the technologies described above, the invention provides a kind of electric cooker telechirics, this electric cooker telechirics effectively can ensure that communication can meet control overflow, conflict can not be produced with other communications applications, and install easily, no matter do not exist and change the high problem of equipment cost, be that person in middle and old age client or young client all can conveniently control simultaneously.

The present invention is achieved by the following technical programs.

A kind of electric cooker telechirics provided by the invention, comprises receiving end carrier module, receiving end signal analysis chip, voltage control circuit, power line carrier module, middle control chip, transformer, communication module, net background; The power supply input of described power line carrier module and transformer access household electric, transformer is controlled chip and household electric is depressurized to 5V in connecting and is delivered to middle control chip, middle control chip connection control power line carrier module; The equal circuit of described receiving end carrier module, voltage control circuit connects power line carrier module, voltage control circuit is all connected receiving end signal analysis chip with receiving end carrier module, and voltage control circuit is also connected electric cooker control circuit with receiving end signal analysis chip; Described middle control chip also understands communication module; Described communication module communication connection family expenses route, and by family expenses route network interconnection network backstage; Household electric is depressurized to 5V and is delivered to receiving end signal analysis chip by described voltage control circuit, and it is electric electric cooker control circuit to be obtained household electric conducting; Described net background mobile terminal receive note, and according to the instruction that short message content comprises, the communication module to middle control chip connection control sends corresponding steering order, simultaneously according to the feedback information obtained, sends note to mobile terminal.

Described middle control chip sends Address Confirmation instruction by communication module and family expenses route to net background when obtaining electric startup, is in waiting status subsequently, and sends state confirmation instruction every the set time to net background, and this set time is not less than 10s; Middle control chip in the wait state, when receiving the steering order of net background, transmitted control signal to receiving end signal analysis chip by power line carrier module, receiving end carrier module, and feedback information is sent to net background by communication module, family expenses route.

Described middle control chip, when starting, after sending Address Confirmation instruction, receives the anticipation network address lastest imformation of net background.
