为了让管廊保持健康运转，海康威视部署了六台巡检轨道机。巡检轨道机上搭载的双光云台红外摄像机 分工明确：可见光镜头结合AI算法，能及时发现管廊侧壁、顶板的细微裂缝，以及内部管线的破损和 渗漏。 管廊内的高压线缆接头、电控箱等过电设备，因运行中电流负载大，容易出现局部过热问题，成为火灾 隐患。对此，巡检轨道机配备的红外热成像仪可实时监测这些设备温度，快速锁定温度异常点位并发出 预警，筑牢火灾防控防线。 对于热力舱管线、高压电力电缆这类长距离铺设且容易发热的特殊管线，仅靠轨道巡检机难以实现全段 全时监测。为此，管廊内部署了海康威视光纤测温系统——将光纤敷设在目标管线上，形成"温度监测 线"，通过光纤传感技术实时捕捉管线温度变化，弥补轨道机的巡检盲区。 同时，管廊内还部署了海康威视各类环控传感器，实时监测管廊内部的氧气浓度、甲烷浓度和温湿度等 环境量；沉降传感器则专注于管廊本体结构的稳定性，确保地下空间安全。 除了对管廊结构、设备与环境等进行智能监测外，海康威视智慧管廊解决方案还聚焦"人员安全"，构建 起包含"作业规范、实时定位、入侵防范"的全方位监测体系。 据悉，管廊内每200米就部署了海康威视高清摄像机及球机，实 ...

当地面上的摩天大楼持续向高空攀升时，地下也在进行着一场关乎城市运转的"生长"——地下管廊正像树木根茎一样 悄然蔓延。截至2022年6月，全国已建成综合管廊总长度5902公里（来源：新华社报道），这些地下"生命线工程"将 水、电、气、通信等各类市政管线集于一体，为管线提供了受保护的物理空间，同时也为运维人员创造了一个便捷的 巡检、维修环境，大幅提升城市管线运维效率。 然而，与地上相比，地下意味着更多的未知。管廊内部空间相对幽闭，还需应对管廊结构沉降、管线泄露、有害气体 积聚等复杂挑战，这对地下空间及管线管道的长期稳定以及运维人员的安全都构成了考验。 2025年，海康威视联合太仓市三峡城市综合管廊建设有限公司，为太仓大道地下综合管廊打造了智慧管廊解决方案， 通过部署各类传感器、巡检轨道机等物联感知设备，实时监测管廊结构、环境、设备状态及人员活动；结合"管廊综合 管理平台"实现对管廊的远程管控、智能预警和应急响应，显著提升运维效率和安全保障能力。 01 物联感知设备协同"把脉" 让管廊监测又快、又准、又全 让人员安全"看得见"、"管得住" 除了对管廊结构、设备与环境等进行智能监测外，海康威视智慧管廊解决方案还聚焦" ...

Core Viewpoint - The significant decline in performance of Dingxin Communications is primarily attributed to external environmental changes, particularly the impact of being "blacklisted" by State Grid and Southern Grid, leading to a drastic drop in revenue and profitability [1][2][3] Financial Performance - In the first half of 2025, Dingxin Communications reported revenue of 704 million yuan, a 50.99% decrease from 1.437 billion yuan in the same period last year [1][3] - The net profit attributable to shareholders was -219 million yuan, worsening from -48.64 million yuan year-on-year [1][2] Business Challenges - The core power business faced unprecedented challenges due to the dual "blacklist" from State Grid and Southern Grid, which is expected to result in a revenue loss exceeding 4 billion yuan over the next three years [2][3] - The company's firefighting business, which was hoped to offset losses, is also struggling due to the downturn in the real estate sector, leading to decreased demand for firefighting products [3][4] Strategic Shift - Dingxin Communications is transitioning from being a "device supplier" to a "solution provider," aiming to diversify its business model and reduce reliance on single-bid markets [2][3] - The company is accelerating its shift towards industrial firefighting, viewing it as a "second growth curve," with new products developed for various applications [3][4] Market Position and Future Outlook - The company has seen its sales in non-real estate markets surpass those in real estate for the first time, indicating progress in business structure optimization [4] - Despite this, the firefighting segment remains unprofitable, with the subsidiary reporting revenue of 157 million yuan but a net loss of 1.54 million yuan [4] - The lifting of the "blacklist" by the two major grids is approaching, with Southern Grid's warning expiring in October 2024 and State Grid's in February 2025, but the long-term impact of these events is expected to persist for 2 to 3 years [4]
