海钓渔船安全检查预警数据
收藏资源简介：
一、适用对象与范围 服务于海事、渔业监管部门，对辖区内登记在册海钓渔船进行常态化安全监管。 二、核心功能与解决问题 通过分析海钓渔船船舶/船员证书有效性、关键安全设备（救生/消防）、通导设备及定位系统状态数据，自动生成 “合格”、“警告”、“严重警告” 三级预警结果。实现自动化、全覆盖、实时风险监测分级，解决人工抽查效率低、覆盖窄、响应慢的痛点。 三、核心价值与外部复用： 1.监管效能倍增：为执法提供精准依据与优先级，大幅提升资源利用效率。 2.事故主动预防：提前预警证书临期、设备故障等隐患，驱动船主自主整改（更新证书、修复设备），有效降低海上安全事故风险。 3.促进合规生态：常态化风险提示规范海钓渔船运营，保障海上安全。其预警数据可复用： ①船主自查自纠：作为船东主动管理安全的依据。 ②保险风险评估：为保险公司提供客观的风险定价参考。 ③行业安全评级：支持第三方机构建立渔船安全信用体系。1.数据采集：采集海钓渔船安全检查记录相关信息，把这些信息存储后用于计算 2.算法加工：使用IFS函数分类汇总出该渔船的各项安全检查数据，①船舶证书情况（船艇适航证书、船检证书、海钓证、保险单据）②船员职务证书情况（船长证）③船名号情况④安全设备情况（救生设备、救生圈、信号弹、灭火器、三色灯、哨子）⑤通导设备（AIS、雷达、罗经）⑥定位系统（北斗）⑦进出港报备⑧其他情况检查，将处理后的数据通过加权平均法：Y=(0.2X1+0.1X2+0.1X3+0.2X4+0.1X5+0.1X6+0.1X7+0.1X8)*100，Y: 海钓渔船安全检查预警分数，X1: 船舶证书情况预警分数，最高上限为1，有效=0，无效=1；X2: 船员职务证书情况预警分数，上限为1，有效=0，无效=1；X3：船名号情况预警分数，上限为1，清楚=0，不清楚=0.5，无=1；X4: 安全设备情况预警分数,上限为1，合格=0、缺少=0.5、无=1；X5：通导设备预警分数，上限为1，合格=0、缺少=0.5、无=1；X6：定位系统预警分数，上限为1，有=0、无=1；X7：进出港报备预警分数，上限为1，有=0、无=1；X8：其他情况检查预警分数，上限为1，通过=0、不通过=1。通过海钓渔船安全检查预警分数，对海钓渔船安全检查预警进行分类分级，得分=0，记为“合格”，0＜得分≤30，记为“警告”，得分>30，记为“严重警告”。
1. Scope and Target Applicants This dataset serves maritime and fishery regulatory authorities, enabling regular safety supervision over registered sea fishing vessels within their respective jurisdictions. 2. Core Functions and Solved Problems By analyzing data on the validity of sea fishing vessels’ and crew qualification certificates, key safety equipment (life-saving and fire-fighting equipment), communication and navigation equipment, and positioning system status, it automatically generates three-level early warning results: "Qualified", "Warning", and "Serious Warning". It realizes automated, full-coverage, real-time risk monitoring and grading, addressing the pain points of manual spot checks including low efficiency, limited coverage, and slow response. 3. Core Values and External Reusability 3.1 Multiplied Regulatory Efficiency: Provides accurate basis and priority for law enforcement, greatly improving resource utilization efficiency. 3.2 Active Accident Prevention: Early warns of hidden dangers such as expiring certificates and equipment failures, prompting vessel owners to take proactive rectification measures (renewing certificates, repairing equipment), effectively reducing the risk of maritime safety accidents. 3.3 Promote Compliance Ecology: Regular risk reminders standardize the operation of sea fishing vessels and ensure maritime safety. Its early warning data can be reused in the following scenarios: ① Vessel Owner Self-Inspection and Self-Correction: As a reference for vessel owners to proactively manage safety. ② Insurance Risk Assessment: Providing objective risk pricing references for insurance companies. ③ Industry Safety Rating: Supporting third-party institutions to establish a fishing vessel safety credit system. 4. Data Collection Collects relevant information from safety inspection records of sea fishing vessels, and stores the collected data for subsequent calculation. 5. Algorithm Processing and Scoring Uses the IFS function to classify and aggregate the safety inspection data of each sea fishing vessel, covering the following 8 aspects: ① Vessel certificate status: Including vessel seaworthiness certificate, ship inspection certificate, sea fishing permit, and insurance documents; ② Crew qualification certificate status: Captain's certificate; ③ Vessel nameplate status; ④ Safety equipment status: Life-saving appliances, life buoys, signal flares, fire extinguishers, tricolor lights, and whistles; ⑤ Communication and navigation equipment: AIS, radar, compass; ⑥ Positioning system: Beidou; ⑦ Port entry and exit declaration status; ⑧ Other inspection items. The weighted average formula is used for scoring: Y=(0.2X1+0.1X2+0.1X3+0.2X4+0.1X5+0.1X6+0.1X7+0.1X8)*100, where Y represents the safety inspection early warning score of sea fishing vessels, and each X term has a maximum cap of 1: - X1: Early warning score for vessel certificate status, 0 for valid, 1 for invalid; - X2: Early warning score for crew qualification certificate status, 0 for valid, 1 for invalid; - X3: Early warning score for vessel nameplate status, 0 for legible, 0.5 for illegible, 1 for absent; - X4: Early warning score for safety equipment status, 0 for qualified, 0.5 for missing, 1 for absent; - X5: Early warning score for communication and navigation equipment, 0 for qualified, 0.5 for missing, 1 for absent; - X6: Early warning score for positioning system, 0 for available, 1 for unavailable; - X7: Early warning score for port entry and exit declaration, 0 for declared, 1 for undeclared; - X8: Early warning score for other inspection items, 0 for passed, 1 for failed. Classify and grade the safety inspection early warnings of sea fishing vessels based on the early warning score: - Score = 0: Marked as "Qualified"; - 0 < Score ≤30: Marked as "Warning"; - Score >30: Marked as "Serious Warning".
