摘要:

在工业生产过程中电子皮带秤普遍采用多个称重传感器输出信号的并联方法,而该方法对多个称重传感器无法独立采集同时无法准确判断故障;应用TI公司MSC1210单片机最小系统和信号分离器,设计一种并联传感器系统压力传感器故障诊断系统,实现多个称重传感器并联应用时的独立采集；发明一种皮带秤称重传感器累计量校准方法,将不断变化的累计量转换成定量值实现并联传感器系统压力传感器故障诊断;结果表明该系统较好实现多个称重传感器的独立采集和故障传感器判断,为皮带秤等计量装置并联传感器系统的技术升级提供有效手段。

Abstract:

Electronic belt scale widely used the parallel method of multiple weighing sensor output signals in the process of industrial production. For each weighing sensor the method cannot separate collection at the same time difficult to determine the fault accurately. Using the TI company MSC1210 single chip microcomputer minimum system and signal separator,to design the pressure sensor fault diagnosis system of the parallel sensor system and to achieve the independent acquisition when the multiple weighing sensor output parallel applications; Invented the cumulative amount calibration method of belt scale weighing sensor,will continue to change the cumulative amount and transformed into quantitative values and realize pressure sensor fault diagnosis of the parallel sensor system. Results show the system better meet the requirements of multiple independent acquisition of the weighing sensor and the fault sensors,for the technology upgrade of parallel sensor system and provide effective means centralized monitoring.
