In-Place Inclinometer固定式测斜仪
7×24 automated deep-displacement monitoring. One RS485 cable chains up to 128 sensors, and a 120 g/m carbon-fiber rod lets a single operator install by hand — even in 60–100 m boreholes. 7×24 小时自动化深部位移监测。RS485 总线一根电缆串联多达 128 根传感器，120g/m 碳纤维杆身让单人徒手即可完成 60–100 米深孔安装。
Real-time data that manual surveys can never capture 捕捉人工巡检不可能发现的实时数据
If the sliding inclinometer solves manual-survey efficiency, the in-place inclinometer answers the need for 7×24 automated monitoring. It samples continuously at minute-level frequency — as fast as one reading per minute — capturing the instantaneous changes a daily site visit could never detect. 如果说滑动式解决的是"人工巡检效率"问题，固定式测斜仪满足的就是 7×24 小时自动化监测的需求。它以分钟级频率持续采集数据——最快 1 分钟一次，捕捉人工巡检根本不可能发现的瞬时变化。
- ✓Carbon-fiber rod, 120 g/m碳纤维杆身，每米仅 120 克
One-fifth the weight of a traditional metal rod — light yet high-strength (≥5.5 kN).仅为传统金属杆身的五分之一——轻巧且高强度（抗拉 ≥5.5kN）。
- ✓One RS485 cable, 128 nodes, AutoIDRS485 一根电缆串联 128 节，AutoID 自动编址
A single bus chains 128 segments; AutoID auto-addressing means no per-unit configuration.单根总线串联 128 节传感器；AutoID 自动编址，安装时无需逐一配置。
- ✓Electrolytic-solution sensor option可选电解质溶液传感器
Proprietary sensing element with 1×10⁻⁸-level long-term stability for multi-year projects.自研敏感元件，长期稳定性达 1×10⁻⁸ 量级，适用于多年期长期监测项目。
A Permanent Sensor String Inside the Casing永久封存在测斜管内的传感器串
If the sliding inclinometer is a stethoscope lowered into the borehole for each visit, the in-place inclinometer is a permanently implanted ECG: it seals the entire manual-survey process inside the grooved casing and runs it automatically, around the clock.如果说滑动式是临时下井的"听诊器"，固定式就是永久植入的"心电图"：它把每次手测的过程永久封存在带导槽的测斜管内，全天候自动运行。
- ✓Permanent, not periodic永久埋设，而非周期巡测
A sliding system competes on flexibility — one probe surveys many boreholes weekly or monthly during construction. The in-place type competes on permanence: installed once, it samples automatically at minute-level frequency with no site visits. Projects running three years or longer, or sites needing remote access, are IPI territory; sub-one-year construction monitoring usually favors the sliding type.滑动式以灵活性取胜——施工期一台仪器多孔轮测，周/月一次。固定式以永久性取胜：一次安装，分钟级自动采集，无需到场。周期三年以上或需要远程查看的项目选固定式；一年以内的施工期监测通常选滑动式。
- ✓Segment number ↔ depth, on record节点编号 ↔ 深度，一一对应建档
Segments are installed bottom-up, and each one is logged into a segment-number-to-depth table as it goes in. Any later anomaly in the remote data maps straight back to a specific segment at a specific depth — so maintenance targets one node instead of guessing.节段自下而上逐节安装，每装一节即录入"节点编号→深度"对照表。日后远程数据出现任何异常，都能直接对应到具体深度的具体节段——维护有的放矢，而非凭空猜测。
- ✓Cloud-managed alarms, automatically云端报警阈值，自动触发
Devices are bound to the cloud platform at the factory; on site, the controller registers and comes online by itself. Engineers then set rate and cumulative alarm thresholds per measuring point — when a reading exceeds them, the platform pushes SMS alerts, with multi-account views for owner, contractor, supervisor and third parties.设备出厂时即绑定云平台，现场部署后控制器自动注册上线。工程师为每个测点配置速率/累计变量报警阈值——数据超限即推送报警短信，并支持业主、施工、监管、第三方多账户视角。
What the Data Looks Like数据长什么样
Each segment continuously measures tilt over its gauge length; the platform converts the chain of readings into a displacement-vs-depth profile. Because sampling is automatic — as fast as one reading per minute — the profile is redrawn continuously, revealing how deflection develops over time instead of waiting for the next manual survey.每节传感器在其标距内连续测量倾角，平台将整串读数换算为"位移-深度"剖面曲线。由于采集全自动——最快 1 分钟一次——曲线持续刷新，变形如何随时间发展一目了然，无需等待下一次人工测量。
On network loss, each string buffers data in 16 GB of onboard storage — over a year of history — and resumes upload automatically once the connection recovers.断网时，板载 16GB 存储自动缓存数据——可保存一年以上历史数据——网络恢复后自动续传。
Built for Unattended, Long-Term Duty为长期无人值守而生
Two figures stand out: 0.05 W per segment means the system runs stably on solar power alone, and 5.5 kN tensile strength keeps deep-borehole installation structurally safe.两个数字值得特别强调：单节功耗仅 0.05 瓦，太阳能供电也能长期稳定运行；抗拉强度 5.5 千牛，确保深孔安装时的结构安全。

"Light yet Strong" — the Design Philosophy"轻而强"的设计哲学
While holding 5.5 kN tensile strength, the carbon-fiber rod cuts weight to one-fifth of a traditional metal rod — so operators install in 60–100 m deep boreholes by hand, with no hoisting equipment.碳纤维杆身在保持 5.5 千牛抗拉强度的同时，将重量降到传统金属杆身的五分之一——60 到 100 米深孔安装可由操作人员徒手完成，无需大型吊装机械。

Long-Term Stability高可靠 · 长期稳定
Even the best MEMS accelerometers drift at the 1×10⁻⁵ level over the years; Rasber's proprietary electrolytic-solution sensor holds 1×10⁻⁸ — three orders of magnitude less drift, ideal for 5-year-plus monitoring.最好的 MEMS 加速度计长期稳定性也只有 1×10⁻⁵ 量级；瑞茨柏自研电解质溶液传感器达 1×10⁻⁸——漂移小三个数量级，是 5 年以上长期监测的最稳方案。
In-place + sliding, better together: the in-place type captures instantaneous changes in real time (such as tidal fluctuations); the sliding type cancels zero drift with forward-and-reverse runs. Combined, they form the most complete deep-displacement monitoring solution. 固定式 + 滑动式，搭配更完整：固定式实时捕捉瞬时变化（如潮汐波动），滑动式通过正反测消除零漂。两者搭配使用，构成最完整的深层位移监测方案。
Installation: 12 Steps, Bottom-Up安装：自下而上 12 步
Before starting: identify the string's top (the segment with the aviation-plug cable) and bottom (no plug), and clamp the steel wire rope to the bottom segment. Three checkpoints gate the whole procedure — fixed-wheel orientation, connecting-rod engagement, and steel-wire-rope lock-off.开始前：先辨认序列头尾——顶部节点带电缆航空插头、底部节点无插头，并将钢丝绳用绳夹固定在底部节点。整个流程有三道"门禁"——固定轮朝向、连接杆对插、钢丝绳锁死。
- 1Compress the spring-loaded wheels压住动轮弹簧
Press the moving-wheel springs on the segment firmly before it enters the casing.用力压住待安装节点本体上的动轮弹簧。
- 2Slide the wheel set into the guide grooves — checkpoint导轮组滑入导槽——门禁
The fixed wheels must face the expected deformation direction of the excavation. Wrong orientation distorts all subsequent data.本体固定轮必须朝向基坑预期形变方向。方向装错，后续所有数据失真。
- 3Mate the connecting rod — checkpoint连接杆对插——门禁
Carefully insert the quick-connect port of the rod above the segment onto the metal connecting rod — fully seated, no gap. Any gap is an error source.将连接杆快速连接端口与本体金属连接杆仔细对插，完全插紧，不留空隙。留缝即是误差源。
- 4Tension and lock the steel wire rope — checkpoint钢丝绳抽紧锁死——门禁
Pull the wire rope through the rod fully taut, then lock the segment's rope clamp. An untensioned rope leaves segments unloaded and lets them drop out of position.在连接杆另一端将钢丝绳完全抽紧，再将本节钢丝绳扣紧锁死。未张紧即空载，节段会掉位。
- 5Secure the spare cable扣紧多余电缆
Wind excess cable around the connecting rod and fasten with cable clips, so it cannot rub against the casing wall.将多余电缆缠绕在连接杆上并用电缆扣扣紧，防止电缆在管内摩擦管壁。
- 6Lower and connect the next segment下放并对接下一节
Push the rod down, then insert the next segment's bottom metal rod into the quick-connect port — again with no gap.顺势将连接杆向下推动，把下一节底部金属连接杆插入上一节快速连接端口内，同样不留空隙。
- 7Repeat for every segment逐节重复
Repeat steps 1–5 segment by segment, bottom-up, until the string is complete.自下而上逐节重复第 1–5 步，直至整串安装完成。
- 8Lead out the top cable引出顶部电缆
Bring the top segment's cable and aviation plug out through the side slot of the casing-mouth protector.将顶部节点的电缆及航空插头从管口保护装置侧面孔槽引出。
- 9Seat the casing-mouth protector放入管口保护装置
Place the protector into the casing with its rim pressed onto the casing mouth.管口保护装置放入测斜管内，边缘压紧测斜管口。
- 10Tension the top wire, tighten the screws抽紧顶部钢丝绳，拧紧螺丝
Pull the wire rope above the protector until fully fixed, then tighten the butterfly screws on the protector.抽紧保护装置上方钢丝绳至完全固定，再拧紧管口保护装置上的蝴蝶扣螺丝。
- 11Stability check before power上电前稳固检查
Visually confirm the whole system sits firmly in the casing before energizing anything.先目视检查整套系统是否稳固安装在测斜管内，再上电。
- 12Power up and go online接电上线
Connect power and the controller, then bring the string online on the cloud platform — and verify the first remote reading before leaving site.接电、连接控制器、上线云平台——离场前先在云平台核对首次远程读数。
The Three Gates三道门禁
1 · Fixed-wheel orientation1 · 固定轮朝向
The fixed wheels must face the excavation's expected deformation direction. Installed the wrong way, readings persistently trend to one side — and the only remedy is re-installing with the correct orientation.固定轮必须朝向基坑预期形变方向。朝向装错，数据会持续偏向一侧——唯一的补救是重新拆装、调整朝向。
2 · Connecting-rod engagement2 · 连接杆对插
Every metal connecting rod must be fully seated in its quick-connect port with no gap. A loose segment-to-segment joint is a permanent error source.每根金属连接杆必须完全插入快速连接端口、不留空隙。节间对接松动就是长期误差源。
3 · Steel-wire-rope lock-off3 · 钢丝绳锁死
Tension first, then lock the rope clamp. If the rope will not pull through, the previous segment's clamp is still locked — open it before pulling. An untensioned rope leaves segments unloaded and out of position.先张紧，再锁死绳夹。钢丝绳抽不动，说明上一节绳夹仍处于锁死状态——先打开再抽。未张紧即空载，节段会掉位。
Field rule: no matter how tight the schedule, if any of the three checkpoints — fixed-wheel orientation, rod engagement, wire-rope lock-off — is wrong, stop and redo it. Continuing and patching later always costs more than redoing now. 现场红线：无论时间多紧，固定轮朝向、连接杆对插、钢丝绳锁死三件事任何一件做错，都必须停下来重做。继续装下去再补救的成本，永远高于停下来重做。
