Real time monitoring of the tower liquid level changes, monitoring process intelligent, LCD display realtime display of liquid level, when the level exceeds the set value of the upper or lower buzzer alarm, LED lights flashing alarm. According to the main function of the remote monitoring system, the design scheme is presented and demonstrated. Design includes two parts of hardware design and software design. The hardware includes the smallest singlechip microputer, the matrix keyboard module, the wireless transceiver module, the display module and the alarm module of the five parts. Singlechip selection macro crystal STC STC89C52。 matrix keyboard input level simulating data value is passed to the wireless module, and data processing。 1602 LCD display tower liquid level information, and a parison with the input value。 lightemitting diode and the buzzer to alarm for abnormal situation. Software using modular design method, mainly divided into main program, wireless transmitting subprogram module, wireless receive subroutine, key detection subroutine, liquid crystal display subroutines, alarm module subroutine six parts. The system of hardware and software debugging, the simulation level of data through nrf24l01 module is transmitted to another nrf24l01 wireless module, through the microcontroller decoding display on the LCD display, when the numerical received more than 1000 or less than 10 ,the buzzer and the lightemitting will give an alarm.
