摘　　要：为了解决目前汽车燃油加热器采集系统存在的问题,研制了一种基于RS-485总线的汽车燃油加热器数据采集系统。该系统采用触摸屏输入员工的信息、产品编号以及进行各项参数的设定;随后,采集模块将加热器的各项数据输入到PLC,并采用最小二乘法对温度测量数据进行修正。运行效果表明,系统操作简单、数据准确、适用性强,具有较高的推广价值。In order to solve the problem that existing in current data acquisition system for automotive fuel oil heater, the data acquisition system based on RS-485 for automotive fuel oil heater has been researched and developed. In this system, the personnel information, product serial number and various parameters are input and setup by using touch screen ; all the data of the heater are input to PLC through acquisition module later; and the measurement data of temperature are corrected with the least squares method. The operation results prove that the system offers easy operation, accurate data and good applicability; it possesses higher promoting value.
