【正文】 where the first instruction of the program to the PC, and then made for each mand to be executed, the PC in the content will automatically increase, increase The amount is determined by the instruction length of this article may be 2 or 3, to point to the starting address of the next instruction to ensure the implementation of the instruction sequence. Microcontroller tower water level control system is the basic design requirements: inside the tower, we have designed a simple water level detection sensor used to detect the three water level, the low water level, the normal water level, water level. Low water to give a high singlechip, driven pumps and water, the red light。 water level in the normal range, the pump add water, the green light。 high water when the pump without water, the yellow light. The design process using the sensor technology, microputer technology, and light alarm technology and weak control the strong power of technology. Technical parameters and design tasks: 1, the use of the MCU to control the water level on the tower。, the water level in the water level detection sensor probe was the tower to give the microcontroller in order to achieve the water pump and water system and display system control。 3, the light alarm display system circuit, pumps and hydropower route relay control。, analysis is drawn on the working principle of the system structure and a system block diagram using the microcontroller as a control chip, the main work process when the water in the tower low water level, water level detection sensor gave a high microcontroller, microcontrollerdriven pump to add water and display system so that the red light lit。 pump add water when the water level within the normal range, the green light, when the water level in the highwater mark, The microcontroller can not drive the water pump to add water, the yellow light. Light alarm circuit, the relay control circuit it works: When the water level in the low water, low water level detection sensor line is not +5 V power supply guide pass into the regulator circuit is treated in the output of the voltage regulator circuit has a high level, into the port of the microcontroller, another high voltage circuit output of the microcontroller port SCM After analysis, the port outputs a low red light, drive, P1. 5 out a signal so that the optocoupler GDOUHE guide through so that the relay is closed, so that the water pump to add water。 when the water level in the normal range, water pump plus pin to a low level, so that the green light。 when the water level in the highwater zone, the sensor of the two detection lines are conduction, are +5 power conduction into the SCM, SCM After analysis, the pin out of a low yellow light, The optocoupler guide a low out of the can not pass, so that the relay can not be closed, the pump can not add water。 failure when three flashing light indicates the system.
