Calculate the displacement and driving car need wheel Angle, and then sends the data to the machineUnder the machine after receiving data, through software programming to control the car wheel rotation speed and Angle, so that it is in accordance with the scheduled path forwardA plete control system requirements of the system is closely linked to each function module, according to the order process and the relationship between them, the total design scheme of the system is available. design of basically has the following several modulesInformation collection modules: information collection part is posed of photoelectric detection and operation amplifier module, photoelectric detection were tracing test and speed test of two parts. Will detect the signal after budget amplifier lm324 amplification module plastic for SCM processing, its core part is several photoelectric sensor.Control processing module, processing module is a stc89c52 MCU as the core, the microcontroller will be collected from the information after the judgement, in accordance with the predetermined algorithm processing, the processing results to the motor driver and liquid crystal display module, makes the corresponding action.Perform modules: module consists of liquid crystal display (LCD), motor drive and motor, buzzer of three parts. Are handled will microcontroller LCD realtime display of the result, convenient for users to understand the current state of the system in time, motor driver based on single chip microputer instruction for the two motor movements, can according to need to make the corresponding action such as acceleration, deceleration, turning and parking, in order to achieve the desired purpose. Buzzer is mainly according to the requirements in a specific location to make a response to the report.references[1] naijing editor, development status and trend of mobile robot [J].
