如图1所示，为本发明实施例所提供的一种高温气冷堆控制棒棒位监测方法，包括：
S110：获取高温气冷堆控制棒的驱动电机动作信号、步进检测信号和上极限位信号。
本发明的方法在进行高温气冷堆控制棒棒位监测时，依托于如图2所示的监测装置进行。具体的，该装置包括：控制棒驱动器1、控制棒棒位变送器2、控制棒驱动电机3、传动机构4、备用步进检测器5、轮毂机构6、步进检测器7、上极限位开关8、控制棒9；
控制棒驱动电机3、传动机构4、轮毂机构6、上极限位开关8顺次连接，控制棒驱动电机3连接控制棒驱动器1，上极限位开关8连接控制棒9。
控制棒驱动器1为控制棒驱动电机3的动力控制装置，内部包含两个动力控制模块，每个模块独立连接到控制棒驱动电机3的一个绕组，均可实现控制棒驱动电机3的转动控制；两个控制模块互为备用，一个模块出现故障后，另一模块立即启用。图2中，11表示控制棒驱动器输出端子，12表示控制棒驱动器输入端子，通过控制棒驱动器输入端子12获取步进电机的电机动作信号，识别具体类型，并通过控制棒驱动器输出端子11发送至控制棒棒位变送器2。
控制棒棒位变送器2为控制棒9控制逻辑处理装置。图2中，21表示控制棒棒位逻辑处理器，22表示控制棒棒位变送器输入端子，23表示控制棒棒位变送器输出端子。通过控制棒棒位变送器输入端子22接收电机动作信号、步进检测信号及上极限位信号，通过控制棒棒位变送器2内部的逻辑处理器进行逻辑处理，得到故障信号、限位输出信号及棒位输出信号，并通过控制棒棒位变送器输出端子23输出。
控制棒驱动电机3为双绕组步进电机或伺服电机，采用一用一备的绕组设置，采用外花键或平键与传动机构4的输入轴连接。
传动机构4由行星轮减速器41、电磁离合器42和电磁阻尼器43组成，起到传动、限速和棒位保持功能。
备用步进检测器5为安装在轮毂机构6齿轮侧边的涡流传感器；轮毂机构6齿轮顶部与涡流传感器探头之间距离随着齿轮转动发生周期性；轮毂机构6每转动一个齿间距，涡流传感器的信号发生一个周期性的变化；涡流传感器的监测信号通过导线传递给控制棒棒位变送器2，将一个周期性变化识别为一个步进信号，实现控制棒棒位的在线监测；备用步进检测器5的检测信号作为控制棒棒位变送器2的备用比对信号，校准主信号的准确度并在主信号故障时作为紧急棒位测量信号使用。
轮毂机构6为阶梯状圆筒形结构，下部安装有钢丝绳导轮，上部圆筒上开有导缆槽，用于钢丝绳缠绕时的导向；圆筒两端有齿轮，左侧为平齿轮，用于运行过程中棒位监测，右侧为锥齿轮，与传动装置的锥齿轮啮合，将步进电机的旋转运动传递到轮毂机构6；中间有轴，轴两端安装轴承；钢丝绳最终紧固在轮毂一侧的锥齿轮固定孔上。
步进检测器7为安装在轮毂机构齿轮对侧的另一个涡流传感器；轮毂机构6齿轮顶部与涡流传感器探头之间距离随着齿轮转动发生周期性；轮毂机构6每转动一个齿间距，涡
流传感器的信号发生一个周期性的变化；涡流传感器的监测信号通过导线传递给控制棒棒位变送器2，将一个周期性变化识别为一个步进信号，实现控制棒棒位的在线监测；步进检测器信号作为主要棒位检测信号，监测结果作为反应性控制的主要依据，在步进检测器7故障时，需进行停堆检修，备用步进检测器5仅作为停堆时棒位指示使用。
上极限位开关8是安装有行程开关的环套管结构，环套管中间开孔尺寸可以通过钢丝绳，但无法通过控制棒9，在环套管内部设置行程开关，使控制棒提升至上极限位置时接触行程开关，触发上极限位信号。
本发明采用的控制棒9为链节式节棒结构；采用备用棒位和逻辑棒位双重验证，确保棒位测量的准确性；通过上极限位开关实现棒位漂移监测，修正因高温蠕变等原因导致的钢丝绳伸长，使反应性控制更为精准；设置采用双绕组电机和双驱动模块设置，使驱动机构可靠性提高，保证反应堆的安全性。
