蓝天白云下的渭南市城区。 蓝天，不仅是气象指标，更是城市治理水平和发展理念的真实映照。在陕西省渭南市，这份"蓝天之约"不是一句口号，而是一项项实打实的攻坚行动。从治 理"看得见的烟"，到盯紧"看不见的气"，从清理地头一把火，到拦截路上超标车，每一个决策的背后是"见微知著"的技术逻辑，更是"咬定青山不放松"的城 市决心。 数据印证了这一事实：2024年，渭南市中心城区环境空气质量综合指数为4.541，空气质量综合指数、优良天数、PM2.5浓度均创有监测记录以来最佳；截至 今年6月30日，渭南市优良天数118天，同比增加9天；六项污染物浓度"五降一升"。 科技赋能从人工到智能的跨越 7月4日上午10时许，渭南科顺新型材料有限公司门口，一辆大货车驶来，门口上方的高清摄像头精准识别，挡车杆随即自动抬起，一旁的运输监管屏即时显 示出车牌号码、排放阶段、通行时间、通行数量、通行提示、管控状态等信息。 "这就是我们企业升级后的环保门禁系统，能自动拦截国三以下货车，既提升效率，又降低人工误差，还能形成环保数据闭环。"公司安环部主管高子华说， 大货车进出厂区，门口摄像头抓拍车牌，系统比对排放数据库，达标秒放，不达标报警，并生成 ...

Core Viewpoint - The implementation of an upgraded environmental access control system in key vehicle enterprises in Pucheng County, Shaanxi Province, enhances the efficiency and precision of pollution management, contributing to the broader goal of air quality improvement. Group 1: Environmental Access Control System - The new access control system automatically connects to vehicle emission databases and the municipal environmental supervision platform, allowing for real-time monitoring and management of high-emission vehicles, preventing non-compliant vehicles from entering the facility [1][2] - The system captures vehicle data, including license plate numbers and emission status, and automatically uploads this information to the municipal regulatory platform, significantly reducing manual verification errors and improving operational efficiency [1][2] Group 2: Impact on Companies - Companies like Weinan Keshun New Materials Co., Ltd. have reported increased efficiency and reduced manual workload due to the new system, which allows for streamlined vehicle registration and monitoring [2] - The upgraded system enables better data analysis for vehicle dispatch, statistical analysis, and environmental self-inspection, thereby enhancing the company's environmental credit [2] Group 3: Broader Environmental Strategy - The initiative is part of a larger effort to combat mobile source pollution, with Pucheng County actively promoting the construction of environmental access control systems in key vehicle enterprises to achieve intelligent and traceable pollution management [2][3] - The local environmental authority plans to explore new models combining access control systems with environmental supervision to create a comprehensive regulatory framework that enhances pollution monitoring and response capabilities [3]
