And stable voltage is provided, infrared receiving circuit can work normally.
The network server is Blynk server；The operation program of remote control equipment is arranged in pairs or groups using Arduino software
ESP8266-CORE is developed in library, and HTML code is developed using Visual Studio Code, passes through 7ZIP boil down to gz lattice
Formula is carried out cross compile to it in Windows system, is obtained with SPIFFS Upload software upload to SPIFFS file system
To the binary code that can be run on risc platform, binary file downloaded to using USB TO UART downloader embedding
Enter in formula processor；Main control chip U1 includes the extraction of serial communication interface and the extraction of reset pin, and reset signal is low
Level is effective, powered on moment, peripheral capacitors conductive, reset pin（RST）Level is pulled low, and generates a reset signal, and one section
After time, capacitor gradually charges, and voltage is equal to 3.3V gradually, and reset signal disappears, it is desirable to download program for main control chip U1, need
To enter UART bootmode after the reset, the start-up mode after main control chip U1 resets selects to depend on the level of 3 GPIO,
After electrification reset, the pin of main control chip U1 is defaulted as high level, therefore GPIO2, without processing, GPIO15 needs a drop-down electricity
Resistance so that it becomes low level, meanwhile, the level state of GPIO0 will determine to be in UART bootstrap mould after main control chip U1 resets
Formula or normal operation mode only need to keep key to be in when needing program to download before IDE issues downloading reset signal automatically
The state being pressed；And after main control chip U1 enters normal mode of operation, the level of GPIO0 will not influence main control chip again
The operational mode of U1, while GPIO0 pin level can be by software control.

Enter frame and WiFi Password Input frame, clicks " after connection button ", execute the JavaScript code in webpage, can check first
Whether SSID and password are legal, and the POST request to " Link_wifi.x " can be initiated after confirmation is errorless, and the data of request include
" SSID " and " PASS ", the network configuration hot spot that the connection that controller receives can be tentative after POST request is submitted, when connecting into
When function, " 1 " can be returned to, browser just will pop up the dialog box of " successful connection " at this time, and at the same time, main control chip U1 can also be incited somebody to action
Configuration files are written in this network configuration, and restart, and complete initial setting, will use the auth in program after remote terminal successful connection
Code key connects network server, and after successfully docking, network server begins listening for server event, and mobile phone terminal downloads software
Blynk simultaneously logs in corresponding account, and so far the deployment of remote terminal is fully completed, and Blynk operational order has entity pin and void
Quasi- two kinds of modes of operation of pin, mobile phone can send modification instruction, then network service after clicking corresponding button to network server
This section of instruction is also sent to remote terminal by device, and remote terminal is made to issue the infrared signal that can be identified by electric appliance, remote terminal
Learning functionality records the infrared information of original product, by re-emitting remote control of the data recorded the realization to electric appliance, this function
Control instruction can be assigned by the Blynk application program remote inside network server, be realized according to infrared receiving circuit；Work as master
After control chip U1 receives infrared signal, the waveform height to original signal, duration are subjected to detailed record, are converted into
Text information, this process can be completed by third party's open source library IRremoteESP8266, and system judges the corresponding button after conversion
Infrared information file whether there is, if it is present being deleted and creating new file, new infrared information be written, if literary
Part is not present, then creates the file of corresponding title according to the key serial number of Blynk and infrared information is written to network service
In the file system of device, the calling of infrared data is then to be sent out using the retrieval to file according to the key of the corresponding serial number of Blynk
It instructs out, whether system has corresponding infrared information file according in sequence number search file system, if it is not, adjusting
The information for returning to a reading file error in window is tried, if smoothly retrieving file, data are loaded from file system
To memory；It such as needs to issue the data of record by infrared transmitting circuit using IRremoteESP8266, resets remote terminal
The method of connection WiFi is the reset button of long-pressing 6 seconds after booting, external interrupt can be triggered when pressing reset button, and open
One duration, 6 seconds timers, the meeting Off Timer when decontroling reset button, hold button can trigger timing after pressing 6 seconds
Device interrupts, and all configuration files can be destroyed in the interruption and are restarted, and guidance Setting pattern will be entered when being again started up.
The present invention includes network server and remote terminal, remote terminal it is small in size, low energy consumption, can networking control, more
New information, across the inter-product type remote control of brand, compared to traditional IR remote controller, remote terminal can access internet and realize far
Process control, household electrical appliances can be adapted to again after updating, and have good recycling rate of waterused, save the cost of building smart home.
Above embodiment cannot limit the protection scope of the invention, and the personnel of professional skill field are not departing from
In the case where the invention general idea, the impartial modification and variation done still fall within the range that the invention is covered
Within.
