 3总线扫描通信交替闪烁电路故障，电路强制同步闪烁无CPU通信-块号冲突OFF闪烁电子设备/端子组件不匹配OFF无块电源，或块故障热电偶输入块2002年6月GFK-0055D 4块操作A热电偶输入块有三对隔离输入。变压器隔离电源，光耦合器提供信号隔离。对于每对输入：1.滤波后，每个信号输入被依次切换到公共放大器，其输出被施加到电压-频率转换器。VFC的输出信号频率通过光耦合器加到频率计数器。输出频率被计数400毫秒的选通时间，这提供了对线路频率拾取的抑制。2.多路复用器在两个主热电偶输入时间之间散布其他输入。这些其他输入来自冷端传感器和内部参考。测量并存储冷端输入，以便以后补偿正常热电偶输入测量误差。3.为了检测和校正放大器或VFC中的任何增益或偏移漂移，该模块在操作期间读取工厂校准的内部参考电平的新读数。将这些新测量值与块存储的参考值进行比较。4.处理器将冷端温度值转换为所用热电偶类型的电压。communications for 3 bus scans Alternate Blinking Circuit fault, Circuit forced Synchronous Blinking No CPU communications - block number conflict OFF Blinking Electronics/Terminal Assembly mismatch OFF OFF No block power, or block faulty Thermocouple Input Blocks June 2002 GFK-0055D 4 Block Operation A Thermocouple Input Block has three isolated pairs of inputs. Transformers isolate power and optical couplers provide signal isolation. For each pair of inputs: 1. After filtering, each signal input is sequentially switched into a common amplifier whose output is applied to a voltage to frequency converter. The output signal frequency of the VFC is applied to a frequency counter via an optical coupler. The output frequency is counted for a 400 millisecond gate time, which provides rejection of line frequency pickups. 2. The multiplexer intersperses other inputs between the two main thermocouple input times. These other inputs come from the cold junction sensors and from internal references. The cold junction inputs are measured and stored for later compensation of the normal thermocouple input measurement errors. 3. To detect and correct for any gain or offset drift in the amplifier or VFC, the block takes new readings of factory-calibrated internal reference levels during operation. These new measurements are compared to reference values stored by the block. 4. The processor converts the cold junction temperature value to a voltage for the thermocouple type in use.
