Described WIFI serial port module 2 uses the integrated chip of ESP8266, outer plus a 10K, a 1K resistance and the resistance of a 100R, also 104 electric capacity.
Described kernel control module 4 uses arm processor STM32F103C8T6, STM32 and ESP8266 to be communicated by USART, and the level of their GPIO mouth is all 3.3V, without pre-add level switch module.
Described ULN2003 module 6 is high electric current Darlington pressure, big display, is made up of seven silicon NPN Darlington transistors, and every a pair Darlington of ULN2003 module is all connected the base resistance of a 2.7K.
Described AC-DC power module 8 uses voltage dropping power supply module HLK-PM01, and 220V is turned 5V.
Described ASM117 Voltage stabilizing module 9 uses SOT-223 to encapsulate, and it is internally integrated overtemperature protection and current-limiting circuit.
Described relay module 10 uses 4 SRD-05VDC-SL-C relays.
Described TTL module 12 uses MAX3232 chip, the single supply electrical level transferring chip of standard serial port, uses+5V single supply to power.
With STM32F103C8T6 chip as control core, relay module 10 is as change-over circuit, instruction is initiated with mobile phone terminal app, hardware components WIFI serial port module 2 receives instruction, pass to main control chip STM32F103C8T6, instruction is resolved by main control chip, instruction good to the instruction parsed and the other side's agreement is contrasted, last main control chip just can control peripheral relay, motor according to this instruction, relay module 10 can drive the electric light of family, fan etc., and motor can be used to drive the door of family, curtain.Reasonably mechanical encapsulation, can realize app-things system.Make pcb board by hand, see that Fig. 4 is intelligent domestic system PCB circuit diagram.After PCB prints with transfer paper, it is transferred on copper coin with flatiron, with the copper coin after transfer, is put into the corrosion of caustic (ferric chloride) warm water, after sand papering.
Software is the WIFI hot spot that the WIFI serial ports of Android platform infinitely controls program, first mobile phone ESP8266 to be connected module, and startup program can enter the interface of mastery routine, connects IP and the port of ESP8266.There are the frame that IP address is arranged, also port numbers in the interface of program, is 8 button controls controlling household electrical appliance with that, each control has corresponding audiomonitor, when a button is depressed, sends and instruct to STM32 single-chip microcomputer accordingly.So the function of software is first to can connect to IP and the port of ESP8266, the equipment of correspondence secondly can be opened and closed exactly.Facility switching has the switch of 3 electric lights, and also fan (socket) switch, is exactly also the switch of door, and they can control corresponding relay on-off respectively.Mobile phone is that the agreement by TCP/IP completes with communicating of WIFI serial ports.User interface uses reference software frame structure, it is provided that interactive operation intuitively, five operating user interface simplicity.Every a pair Darlington of ULN2003 module is all connected the base resistance of a 2.7K, and under the running voltage of 5V, it can be joined directly together with TTL and cmos circuit, can directly process the data originally needing standard logic buffer to process.
When the intelligent domestic system work controlled based on STM32 Yu Android:
Open circuit switching plate 5, then opens mobile phone WIFI and arranges, connect focus (WILDFIRE), and initial password is E12345678;Opening " Internet of Things household ", startup program can enter the interface of mastery routine, connects IP and the port 13 of ESP8266, clicks on the cross in the upper right corner, interface, will become hook number, represents successful connection;Here it is control 8 button controls (14-23) of household electrical appliance, corresponding audiomonitor is had on each control, when a button is depressed, send and instruct to STM32 single-chip microcomputer 4 accordingly, hardware components WIFI serial ports 2 receives instruction, passes to main control chip STM32F103C8T6, and instruction is resolved by main control chip 4, instruction good to the instruction parsed and the other side's agreement is contrasted, and last main control chip 4 just can control peripheral components according to this instruction.Then first lamp 18 can be lighted;Light second electric light 17.Close first lamp 19, then turn on second lamp 20.First can close all of equipment 23, click on door close button 22 after then clicking on door open button 15, or several seconds again, will rotate and reverse by steering wheel 1, the angle of rotation oneself can be arranged inside program.Clicking on and open all devices 14, all of electric light 7 is the most light, motor 1 rotates, also have socket 11 the most automatically to power on;Clicking on and close all devices, all of electric light 7 has all gone out, motor 1 stops operating, also have socket 11 also to automatically power off.
Electric light 7 controls: the electric light 7 of family is typically all 220V voltage, in order to control 220V household electrical appliances, native system uses relay 10, uses the normally opened and normally-closed contact of relay 10 to realize.
Socket 11 controls: traditional household socket, it is simply that simply realize power supply conveying, and socket 11 can realize mobile phone to be opened or closed the power supply of socket, it is achieved controlled in wireless.
Door and window controls: accurately control the corner of steering wheel 1, uses PWM pulse-width controlled, reaches the purpose of precise positioning point, steering wheel 1 is arranged on the door and window of family, control the door and window of family with steering wheel 1.Steering wheel module 1, the running voltage of small-sized steering machine 1 is generally 4.8V or 6V, and rotating speed is not quickly, and its operation principle is that control signal is by the passage entering signal modulation chip 4 of receiver, it is thus achieved that DC offset voltage.Having a reference circuit inside it, the generation cycle is 20ms, and width is the reference signal of 1.5ms, by the voltage ratio of the DC offset voltage obtained and potentiometer relatively, it is thus achieved that voltage difference exports.Finally, the positive negative output of voltage difference determines the rotating of motor 1 to motor 1 driving chip.When the timing of motor 1 rotating speed one, potentiometer is driven to rotate by cascade reduction gearing so that voltage difference is zero, and motor 1 stops operating.Controlling it is generally required to the time main pulse of an about 20ms of steering wheel 1, the high level part of this pulse is generally the Angle ambiguity segment pulse in the range of 0.5ms-2.5ms.
Program part is broadly divided into: Single Chip Microcomputer (SCM) program and APP design program:
1. singlechip main program:
int main ( void )
{
PWM_Init(); The output of //PWM steering wheel pulsewidth initializes
USARTx_Config(); // initialize serial ports
SysTick_Init(); // initialize ticking intervalometer
ESP8266_Init(); // initialize ESP8266
LED_Init (); // initialize LED
ESP8266_StaTcpClient_UnvarnishTest ();// wait instruction order
while(1);
}
2.APP designs part mastery routine
Program // enter the to join id of // packing instruction is to specify which button opt to refer to the function selected
public byte[] packageCmd(byte id,byte opt) {
byte[] cmd=new byte[]
{0x43,0x4D,0x44,0x5F,0x4C,0x45,0x44,0x5F,id,0x5F,opt};
return cmd;
}
Above-mentioned design part mastery routine for singlechip main program and APP.
The above-described presently preferred embodiments of the present invention that is only, but the interest field of the present invention can not be limited with this, and the equivalence that therefore the claims in the present invention are made replaces, revise and improvement etc., still falls within the scope that the present invention is contained.
