Research of intelligent remote control parking space based on single chip microcomputer
Abstract
At present,theresearch of intelligent parking lock has been a group of pioneers, they have great significance to promote the development of parking lock in the research of this topic, to meet the needs of the market and the owner. In this paper, the research background of parking lock is briefly introduced, then the current research status is analyzed, and the significance of the research topic is discussed. Then, the research program of this paper is introduced, namely, how to implement the control of parking space lock by remote control, which is mainly related to the wireless transmitting and receiving and circuit driver. And the system introduced the hardware, MCU 51 contains, transmitting and receiving chip PT2262 / 2272, L298 driver chip. It mainly introduces the pin definition of these chips, circuit principle and work process. Finally, the design scheme of contact to the use of the software are introduced in this paper, and a description of a software program, gives the design procedure, and an additional simulation circuit diagram, program input to the simulation of the circuit in the final simulation.
Keywords: remote control parking lock wireless transmission and reception simulation
