Principle of remote door and window opening and closing system

principle of remote door and window system

principle of remote door and window system. In life, remote door and window system has become particularly common, among which single chip microcomputer system is a very important part of remote door and window system, so today I will explain the principle of remote door and window system for you. Principle of remote door and window system 1

Analysis of temperature and humidity based on single chip microcomputer The working principle of remote door and window system is as follows:

The temperature and humidity remote control system is mainly collected by SHT11 sensor, and the collected temperature and humidity are input to P1 and interfaces of AT89C51 of single chip microcomputer, and SCK signals are input to P1 and 1 interfaces of single chip microcomputer, and the received data are forwarded to STBY interface of MICR12 by P1 and 2 ports of single chip microcomputer. The DATA information received by the P1 and interfaces is forwarded by the P1 and 3 interfaces to the No.8 interface of MICRF12, and the data information is converted into a transmittable radio wave signal via MICRF12, which is transmitted by the self-made antennas of the No.6 and No.7 interfaces. The signal is received by MICRF2 at the user end. After the signal is converted, it is output to 8C51 single chip microcomputer. Then the single chip microcomputer analyzes the temperature and humidity and the internal clock to control the relay, so as to finally control the forward and reverse rotation of the motor, and finally achieve the effect of automatically closing the doors and windows.

the system is mainly composed of five parts, in which SHT11 sensor and AT89C51 microcontroller are used to collect and sum signals, MICRF12 is used to transmit digital signals, and MICRF2 receives digital signals, which are demodulated and transmitted to AT89C51 microcontroller, and finally the relay controls the motor to rotate forward and backward.

Mobile phone remote control switch (YD238-6) "Mobile Butler" brand: Insert a mobile phone card, connect to the power supply (22V or 12V), and you can access this controller anytime and anywhere by SMS, so as to operate household appliances, industrial motors and other electrical equipment, and achieve the purpose of remote control of electrical equipment by SMS. (Without any telephone line) This system can be remotely controlled and set by SMS. The specific functions are as follows:

1. The GSM controller can directly drive multiple relays. Multiple relays can be remotely controlled by SMS.

2. It has the function of sending back the remote control results of short messages.

3. The uniqueness of user password must be controlled by password.

4. Chinese is used as SMS remote control instruction, which can be customized by users.

5. remote control function: you can remotely control the operation of electrical appliances through short messages.

6. inquiry function: you can send short messages to inquire about the working status of an electrical appliance.

7. state change return function: after the working state of an electrical appliance changes, it will be automatically sent to the fixed mobile phone by SMS.

phone setting function: set the default control.
