功能描述
IS200VTCCH1CBC是GE公司开发的热电偶处理器板。它是Mark VI控制系统的一部分。该板设计用于接受24种不同类型的热电偶输入，包括E型，J型，K型，S型或t型。热电偶输入连接到位于终端板上的两个端子块，称为TBTC。这些接线端子作为热电偶电缆的连接点。
特性
通信接口:配有模制插头的电缆便于终端板(TBTC)和VME机架之间的连接，VME机架是VTCC热电偶处理器板的所在地。这确保了热电偶输入和处理单元之间的无缝通信。
Simplex和TMR控制:根据系统要求，TBTC端子板提供了灵活的配置。它可以支持单工(TBTCH1C)和三模冗余(TMR)控制(TBTCH1B)。这允许基于冗余需求和系统架构的定制集成。
安装
安装终端板:首先将终端板安全地安装在系统设置内的指定位置。
热电偶输入接线:将热电偶输入连接到TBTC上的端子排。确保适当的标签和组织，以方便识别和排除故障。
连接到VME机架:利用带模制插头的电缆在终端板和VME机架内的VTCC热电偶处理器板之间建立连接。
配置灵活性:根据应用的具体要求，可根据需要将终端板配置为单工控制模式或TMR控制模式。
测试和验证:安装后，进行彻底的测试和验证程序，以确保热电偶输入和处理单元之间的正常功能和通信。
故障检测
高/低(硬件)限制检查:定期执行硬件限制检查，以检测与预设的高/低水平的任何偏差。这些限制的设置是为了防止可能损害系统完整性或导致设备故障的极端条件。如果测量参数超过或低于这些预定的限制，就会触发故障信号，表明存在需要注意的异常情况。
高/低系统(软件)限制检查:除了基于硬件的限制检查外，系统内还实施了基于软件的限制检查。这些软件限制是根据系统的操作参数和性能要求来定义的。该软件持续监控系统变量，并将它们与预定义的限制进行比较。当某个参数超过软件设置的高、低阈值时，将触发故障情况，提示相应的纠正措施。
所有tc, CJs，校准电压和校准零读数的监控读数:全面监控扩展到对系统运行至关重要的所有组件，包括热电偶(tc)，冷结(CJs)，校准电压和校准零读数。定期监测这些组件，确保它们在可接受的公差范围内运行，并准确反映系统的运行条件。在监测过程中发现的任何偏差或差异都被迅速标记为潜在的故障或异常，从而促使进一步的调查和纠正措施。

Functional Description
IS200VTCCH1CBC is a Thermocouple Processor Board developed by GE. It is a part of Mark VI control system. The board is designed to accept inputs from 24 different types of thermocouples, including type E, J, K, S, or T. The thermocouple inputs are wired to two terminal blocks located on the terminal board, known as TBTC. These terminal blocks serve as connection points for the thermocouple cables.
Features
- Communication Interface: Cables equipped with molded plugs facilitate the connection between the terminal board (TBTC) and the VME rack, where the VTCC thermocouple processor board is housed. This ensures seamless communication between the thermocouple inputs and the processing unit.
- Simplex and TMR Control: Depending on the system requirements, the TBTC terminal board offers flexibility in configuration. It can support both simplex (TBTCH1C) and triple modular redundant (TMR) control (TBTCH1B). This allows for tailored integration based on redundancy needs and system architecture.
Installation
- Mounting the Terminal Board: Begin by securely mounting the terminal board in the designated location within the system setup.
- Wiring Thermocouple Inputs: Connect the thermocouple inputs to the terminal blocks on TBTC. Ensure proper labeling and organization to facilitate easy identification and troubleshooting.
- Connecting to VME Rack: Utilize cables with molded plugs to establish connections between the terminal board and the VTCC thermocouple processor board housed in the VME rack.
- Configuration Flexibility: Depending on the specific requirements of the application, configure the terminal board for either simplex or TMR control mode, as needed.
- Testing and Validation: Once installed, conduct thorough testing and validation procedures to ensure proper functionality and communication between the thermocouple inputs and the processing unit.
Fault detection
- High/Low (Hardware) Limit Check: Hardware limit checks are performed regularly to detect any deviations from preset high and low levels. These limits are set to safeguard against extreme conditions that could potentially compromise system integrity or lead to equipment failure. If a measured parameter exceeds or falls below these predetermined limits, a fault signal is triggered, indicating the presence of an abnormal condition that requires attention.
- High/Low System (Software) Limit Check: In addition to hardware-based limit checks, software-based limit checks are implemented within the system. These software limits are defined based on the operational parameters and performance requirements of the system. The software continuously monitors system variables and compares them against the predefined limits. If any parameter surpasses the high or low thresholds set by the software, it triggers a fault condition, prompting appropriate corrective action.
- Monitoring Readings from all TCs, CJs, Calibration Voltages, and Calibration Zero Readings: Comprehensive monitoring extends to all components critical for system operation, including thermocouples (TCs), cold junctions (CJs), calibration voltages, and calibration zero readings. Regular monitoring of these components ensures that they are functioning within acceptable tolerances and accurately reflecting the system’s operational conditions. Any deviations or discrepancies detected during monitoring are promptly flagged as potential faults or anomalies, prompting further investigation and corrective measures.
