南京市建邺“智慧消防”建设模式是指建邺区民生消防物联网项目，项目始建于2018年，现在已经建设三期。建邺物联网平台采用标准的采用NB-IoT的数据通讯协议和标准的终端通信协议接入各种品牌厂商的各种消防物联网感知终端设备，感知终端可探测可燃气体泄露、烟雾超标、电气线路过热、消火栓管网压力不足、消防水箱液位不足等信息，向平台上报信息和报警。平台收到报警信息后，如果是故障信息则直接通知运维单位处置；如果是火警或煤气报警则及时通知住户处置警情或者逃生，同时通知附近消防站消防员/消防特勤人员及时核实与处置初期火情，一旦确认真实火警直接推送119智能接处警系统报。
目前，建邺物联网共布设了1万多套消防前端感知设备，包括4000多台无线感烟探测器、6000多台无线可燃气体探测器、176套简易喷淋装置、312套无线水压探测器。终端设备主要分布在建邺区各街道、社区的九小场所、电动车充电点、老旧小区的弱势群体家庭以及群租房等场所，涵盖南京市建邺区各民生工程内的6个街道、72个社区、4个商务建筑、1个派出所。建邺区消防救援大队建立了预警信息三级联动处置机制，成立了大数据中心和24小时监测中心，每天实时采集分析10万条运行数据，及时将预警信息分级分层加推到城市运管企业、行业主管部门和市应急指挥中心，联动处置预警信息。
系统运行以来，实现月均有效报警24.3起，成功预警燃气管网泄漏、烟雾浓度超标、供水管网泄漏、水厂泵站运行异常796多起。较系统应用前，全市地下管网事故发生率下降60%、风险排查效率提高70%。上述场所之前没有安装任何探测报警设备，属于火灾防控的薄弱环节，尤其是电动车充电点和使用燃气的场所。目前正在全面布点阶段，下一步将通过分区分级管理，由街道、社区负责所辖区域具体报警的及时核实、探测设备维保和燃气管线维修督办。
使用案例
可燃气体探测报警后自动关闭管道阀门。在沿街小餐馆安装部分安装机械手的可燃气体探测器，当探测到煤气浓度超标（浓度超标5%LEL）后，系统向用户发出浓度超标报警和附近消防特勤人员，并通过机械手自动关闭管道阀门，避免发生气体爆燃事故。
真实警情
2020年11月18日23点39分，燃气监测系统发现沙洲街道莲花社区寅春老卤面火灾报警器报警。经分析研判为火灾隐患推送给莲花社区值班室。经莲花社区复核确认为因面馆用火不规范导致起火。门面房位于老城区内，周围人口密度较大，老年人偏多，一旦发生火灾，会造成巨大的人员伤亡、财产损失。社区立即对门面房进行整改，至11月19日凌晨整改完成，避免了恶性事件的发生。
据统计，系统平均每日产生5-10条预警信息，经核实，报警信息中可燃气体泄露报警确实为探测浓度值超标所致，系统预警功能正常。平台开通至今安装使用单位和住户未发生火灾事故，整个建邺区同比去年全年接警起数下降了4.79%，未发生九小场所爆燃事故。
南京市“建邺民生工程消防物联网综合子平台”
Nanjing Jianye "smart fire" construction mode refers to Jianye District People's livelihood fire Internet of things project. The project was built in 2018 and has now been constructed in phase III. Jianye IOT platform uses standard NB IOT data communication protocol and standard terminal communication protocol to access various fire IOT sensing terminal equipment of various brand manufacturers. The sensing terminal can detect information such as combustible gas leakage, excessive smoke, overheating of electrical lines, insufficient pressure of fire hydrant pipe network and insufficient liquid level of fire water tank, and report information and alarm to the platform. After the platform receives the alarm information, if it is a fault information, it will directly notify the operation and maintenance unit for disposal; If it is a fire or gas alarm, timely notify the residents to deal with the alarm or escape, and notify the firefighters / fire secret service personnel of the nearby fire station to timely verify and deal with the initial fire. Once the real fire is confirmed, directly push the 119 intelligent alarm receiving and handling system to report.
At present, Jianye Internet of things has deployed more than 10000 sets of fire front-end sensing equipment, including more than 4000 wireless smoke detectors, more than 6000 wireless combustible gas detectors, 176 sets of simple sprinkler devices and 312 sets of wireless water pressure detectors. The terminal equipment is mainly distributed in nine small places in the streets and communities of Jianye District, electric vehicle charging points, vulnerable families in old communities and group rental houses, covering 6 streets, 72 communities, 4 business buildings and 1 dispatch office in the livelihood projects of Jianye District, Nanjing. Jianye District fire rescue brigade has established a three-level linkage disposal mechanism for early warning information, established a big data center and a 24-hour monitoring center, collected and analyzed 100000 operation data in real time every day, and timely pushed the early warning information to urban transportation management enterprises, industrial competent departments and municipal emergency command center in a hierarchical manner to handle the early warning information in a linkage manner.
Since the operation of the system, 24.3 monthly effective alarms have been realized, and more than 796 cases of gas pipe network leakage, excessive smoke concentration, water supply pipe network leakage and abnormal operation of water plant and pump station have been successfully warned. Compared with before the application of the system, the accident rate of underground pipe network in the city decreased by 60% and the risk investigation efficiency increased by 70%. No detection and alarm equipment has been installed in the above places, which belongs to the weak link of fire prevention and control, especially the charging points of electric vehicles and places using gas. At present, it is in the stage of comprehensive distribution. In the next step, the streets and communities will be responsible for the timely verification of specific alarms in the areas under their jurisdiction, the maintenance of detection equipment and the supervision of gas pipeline maintenance through zoning and hierarchical management.
Use case
Automatically close the pipeline valve after combustible gas detection and alarm. The combustible gas detector of the manipulator is installed in the installation part of the small restaurant along the street. When the gas concentration exceeds the standard (the concentration exceeds 5% LEL), the system sends the concentration exceeding alarm to the user and the nearby fire secret service personnel, and automatically closes the pipeline valve through the manipulator to avoid gas deflagration accident.
Real alarm
At 23:39 on November 18, 2020, the gas monitoring system found that the Yinchun old halogen fire alarm in Lianhua community, Shazhou Street gave an alarm. After analysis, it is determined that the fire hazard is pushed to the duty room of Lianhua community. After review by Lianhua community, it is confirmed that the fire of noodle restaurant is caused by non-standard fire. The facade room is located in the old urban area, with large population density and more elderly people. In case of fire, it will cause huge casualties and property losses. The community immediately rectified the front room and completed the rectification in the early morning of November 19, avoiding the occurrence of malignant events.
According to statistics, the system generates an average of 5-10 early warning information every day. After verification, the combustible gas leakage alarm in the alarm information is indeed caused by the excessive detection concentration value, and the early warning function of the system is normal. Since the opening of the platform, there has been no fire accident in the installation and use units and residents. The number of alarm receiving in Jianye District decreased by 4.79% year-on-year, and there has been no deflagration accident in nine small places.
