In order to solve the problem of inaccurate ringing time of existing school bell equipment, we must have an accurate timing system and a reliable device to control the ringing, both of which are indispensable. If only the timing system is accurate, but the equipment that controls the ringing cannot perform reliably, or the equipment that controls the ringing can perform reliably, but the timing system is inaccurate. It is impossible to ring the bell accurately.
In view of the above problems, the solution is as follows: First, using satellite time service can achieve high accuracy, and the program can be set to calibrate every 5s. That is to say, we can keep the same time with the National Time Service Center almost every moment. Second, on the controlled equipment, the wireless drive is adopted, that is, the control system controls our equipment such as ringing through the 2.4GHz radio signal.
The specific method is to use the GPS module to receive the satellite standard time, transmit it to the microcontroller through serial communication, and the microcontroller demodulates the signal to complete the timing of the clock module. The operator can set (ringing time, alarm clock, etc.) through the infrared remote control. The system can transmit the command to the remote relay module through the wireless module according to the time set by the operator, and drive various control devices through the relay module to achieve the corresponding functions
GPS automatic time service, receiving satellite time and completing time service to clock chip; Wireless transmission of control signals to control the work of bell ringing equipment and household appliances or school electrical equipment; The regular ringing function can ring the bell at a fixed time for the ringing device, and can start and shut down the household appliances or school appliances at a fixed time; Fire and earthquake alarm, alarm in case of fire or earthquake, and automatically or manually trigger the alarm device; The perpetual calendar displays the year, month, day, hour, minute, second, lunar calendar, temperature and 24 solar terms on the LCD screen; Birthday reminder and holiday reminder function, using the large screen LCD display to display the corresponding text to remind the family of birthdays and holidays; Software dynamic timing can correct clock error (when GPS is not used) to ensure travel time accuracy; There are two setting modes: button and infrared remote control. Infrared can improve operation flexibility and security.
