| 摘 要： | 提出了以CAN总线扩展超声波测距的基本思想,介绍了一种以AT89C52作为微控制器、SJA1000作为总线控制器和以82C250作为总线收发器的CAN总线智能超声波测距车载系统。与普通超声波测距系统相比,系统增加了CAN总线部分的设计,简化了系统控制核心的工作和硬件设计,并通过利用汽车上现有的资源,可节省硬件设计;另外,CAN总线的扩展也可使后续测距系统的进一步开发变得更为灵活。

| Abstract: | Presents a basic idea of extending ultrasonic distance measurement with CAN bus and introduces a kind of CAN bus-based intelligent ultrasonic distance measurement vehicular system, in which AT89C52 is utilized as microcontroller, SJA1000 as the bus controller and 82C250 as the CAN transceiver. The proposed ultrasonic distance measurement system excels ordinary ones in simplifying the work of the system's cybernetics core and the hardware design. It may well save hardware design since it can apply the available resources in the car. Besides, the extension of CAN bus can make the further development of follow-up distance measurement system more flexible. |
