Water is the basic condition for human survival. Human beings can never live without water. Water is called the sweet spring of life. For a long time, people generally believe that water is “inexhaustible, inexhaustible”. They do not know how to cherish it and waste it. For a long time, most domestic water meters in

AGV path navigation algorithm is one of the key issues to improve the efficiency of AGV operation. In order to avoid AGV deviating from the established path due to the influence of external uncertainties in the operation process, this paper designs a PID controller for differential drive four-wheel AGV, which can accomplish the task of

DDR SDRAM uses double data rate structure. With its advantages of large capacity, high data transmission rate and low cost, it is increasingly used in high-speed data acquisition systems. The function of DDR controller is designed and implemented by using Cyclone FPGA chip of Altera Company. 　　The design idea is described, which has certain practical
