specific Embodiment 1
[0034] Specific embodiment one, such as figure 1 as shown,
[0035] A smart home control App, including a top-level interface and a bottom-level control module, wherein the top-level interface includes three parts, which are a monitoring data display unit, an electrical appliance control button unit, and a new device network access button unit. The environmental data values collected by each sensor, the monitoring data display unit described in this embodiment includes temperature, humidity, gas concentration, brightness, PM2.5 value, wherein, temperature, humidity, PM2.5 value includes living room, bedroom, bathroom The temperature, humidity, and PM2.5 value in the home, the brightness includes the brightness of the living room and bedroom, and the gas concentration includes the gas concentration of the bathroom and kitchen.
[0036] The appliance control button unit is used to select and control various electrical equipment in the home network. The new device network acce...
specific Embodiment 2
[0042] Specific embodiment two, such as figure 2 as shown,
[0043] The configuration data setting process for the new device to enter the network is as follows:
[0044] Step 1. Open the smart home control app and select the new device network connection button;
[0045] Step 2. Set 3 cycles of high level and 3 cycles of low level to represent code '0', 3 cycles of high level and 6 cycles of low level represent code '1', and 3 cycles of high level Level and a low level greater than or equal to 9 cycles represent the beginning of a new byte;
[0046] Step 3, input the configuration data of the new device through the keyboard input module;
[0047]Step 4, the transmitter encodes the configuration data in step 3 according to the encoding rules of step 2, and the encoded signal is a char array;
[0048] Step 5. Call the sound card driver to play the encoded signal through the speaker to generate modulated ultrasonic waves.
specific Embodiment 3
[0050] Take the IP address of the sending device as an example for illustration, and the methods for other parameters are the same.
[0051] For example: the IP address of the new network video needs to be set to 192.168.2.100, the sampling frequency Fs of the sound card of the mobile phone is 48000Hz, and the sound wave frequency Fv is 12000Hz. The encoding process is as follows:
[0052] Step 1. The binary code of the IP address 192.168.2.100 is:
[0053] 11000000 10101000 00000010 01100100, the transmission sequence is first high and then low.
[0054] Step 2, the coding rules are:
[0055] The high level of n cycles and the low level of n cycles represent the code '0'; the high level of n cycles and the low level of 2n cycles represent the code '1'; the high level of n cycles is greater than or equal to The low level of 3n cycles represents the beginning of a new byte. In this example, n takes the value 3;
[0056] The value of the sampling point can be calculated by th...
