Design of a multifunctional curtain controller with indoor anti-theft alarm
provides you with a basic design idea and sample code of key functions to help you start developing a multifunctional curtain controller with indoor anti-theft alarm.
Design ideas:
1. Hardware design: Use 51 microcontroller to control the switch and position of the curtains, and connect various sensors (such as infrared sensors, door magnetic sensors, etc.) to detect intrusions.
2. Curtain control: Use the GPIO port of the 51 microcontroller to control the switch and position of the curtain motor. You can choose the appropriate drive circuit based on your specific motor type.
3. Alarm function: When the sensor detects an intrusion, the alarm function is triggered, such as a buzzer sounding an alarm, and alarm notifications can be sent through other methods (such as text messages, phone calls, etc.).
4. User interface: LCD display and buttons can be added to display curtain status, set parameters and operate the controller.
Sample code:
Below is a simple sample code to control the switch and position of the curtains, as well as detect intrusion and trigger the alarm function. Please note that this is just an example and you will need to modify and extend it appropriately based on your specific hardware and functional requirements.
#include <reg51.h>
sbit curtainOpen = P1^0; // 窗帘打开信号
sbit curtainClose = P1^1; // 窗帘关闭信号
sbit curtainPosition = P1^2; // 窗帘位置信号
sbit alarm = P2^0; // 报警信号
sbit infraredSensor = P3^0; // 红外传感器
sbit doorSensor = P3^1; // 门磁传感器
void delay(int ms) {
int i, j;
for (i = 0; i < ms; i++) {
for (j = 0; j < 1000; j++);
}
}
void openCurtain() {
curtainOpen = 1;
delay(1000);
curtainOpen = 0;
}
void closeCurtain() {
curtainClose = 1;
delay(1000);
curtainClose = 0;
}
void setCurtainPosition(int position) {
curtainPosition = position;
}
void triggerAlarm() {
alarm = 1;
delay(5000);
alarm = 0;
}
void checkIntrusion() {
if (infraredSensor == 1 || doorSensor == 1) {
triggerAlarm();
}
}
void main() {
while (1) {
// 检测入侵
checkIntrusion();
// 检测按键控制
if (P1^3 == 1) {
openCurtain();
} else if (P1^4 == 1) {
closeCurtain();
}
}
}Please note that this is just a simple sample code to demonstrate basic functionality. Actual design and development may require more complex code and hardware connections. You need to make appropriate modifications and extensions based on your specific needs and hardware design.
Hope this sample code helps you! If you need more help or have additional questions, please feel free to ask.
