The Hotel To Send Dish Car Design

Smart devices have good stability and accuracy. Smart devices, smart car with agood economy and accuracy. Smart car can be applied in a hotel, it can complete pathidentification, transportation task dishes, saving the hotel’s economic costs.Determine the car’s functions according to car use environment. Re-design of thesmart car hardware and software systems based on functional trolley system. Thehardware design of the system, including design choices sensors, steering gearselection and circuit. The modular design of the circuit to follow ideological system.After continuous tests found the car hardware system to achieve the intended function.Then according to the car’s functional design software systems, software part consistsmainly of initialization, algorithm design software. Part of the algorithm also followsthe modular idea.Path identification algorithm is to extract the main path. Using the differencebetween the treatment path data, extracting a predetermined path information.Mainstream speed control algorithm PID and fuzzy PID algorithm, the PID controland fuzzy PID control were compared, and finally decided to use fuzzy PID algorithm.After tests found steering servo control algorithm enables normal operation, fuzzyPID can satisfy the needs of the car.
