【摘要】 为了满足商场较大型停车场顾客停车需要导引的需求,文章介绍一种基于单片机的商场停车场导引系统的设计,以AT89C52单片机为主控芯片,采用HC-SR04超声波传感器采集车位信息,通过串行口和n RF24L01无线传输模块向上位机传送数据,上位机软件采用VB编写,利用MSComm控件接收数据。实验表明,此系统具有成本低、功耗低、可靠性高等优点,具有一定的实用性。更多还原

【Abstract】 To meet the needs of customer parking guidance in large parking lots of shopping malls, this paper introduces a design of a parking lot guidance system based on single chip microcomputer. It uses AT89 C52 microcontroller as the main control chip, uses HC-SR04 ultrasonic sensor to collect parking information, and transmits data to the computer through serial port and nRF24 L01 wireless transmission module. The host computer software is written by VB and receives data by MSComm control. The experiment shows that the system has the advantages of low cost,low power consumption and high reliability as well as certain practicability.更多还原
