Description

一种用于施工现场人员安全预警的方法 技术领域
本发明涉及一种用于施工现场人员安全预警的方法,属于建筑施工领域。
背景技术
目前,国内各线城市中均有大型的新建、改建或扩建项目,在大型工地的施工现场,存在诸多危险源,一旦现场各类人员对各类危险源缺乏识别能力或反应不及时,就可能发生生产安全事故,造成生命和财产的直接和间接损失,给社会带来了及其恶劣的影响。目前各类工地中,主要的生产事故为高处跌落,以及物体的主动打击和被动打击,比如,对于大型工地来说,一般洞口临边纵深较大,且引发主动打击的物体较大,往往会直接导致人员死亡事故的发生。
施工现场往往针对不同等级的危险源设定不同的安全防护措施,对于危险源较多的工地,不利于现场管理,也不利于施工人员人为识别。另外,由于施工现场环境较为复杂,固定的防护措施在环境变化时可能会降低安全性,比如露天作业时,当出现大雾天气时,施工人员仍可能误触危险源。
因此亟待开发出一种可应用于所有危险源的安全预警方法。
发明内容
本申请提供了一种用于施工现场人员安全预警的方法,用于解决现有的预警不利于识别,未考虑环境、人员因素对事故发生概率的影响程度。
为解决以上技术问题,本发明包括如下技术方案:
一种用于施工现场人员安全预警的方法,包括:
服务器中预设一级安全距离L 1和二级安全距离L 2,其中L 1>L 2
在电子地图中标识出危险源,设定危险源等级,并根据危险源具体情况设 定危险源安全因子N 1;采集施工人员的信息,并针对施工人员分别设定人员安全因子N 2;根据环境变化,设定环境安全因子N 3
佩戴有定位装置的施工人员进入施工现场后,施工现场中设置有与定位装置匹配的位置采集装置,位置采集装置采集施工人员的位置并上传至服务器;
服务器中设置一级预警实际触发距离L 10、二级预警实际触发距离L 20的计算公式,服务器计算与最近危险源的距离是否小于等于L 10,若是服务器则控制施工现场的警报装置发出一级预警信息,并计算与最近危险源的距离是否小于等于L 20,若是服务器则控制施工现场的警报装置发出二级预警信息;其中,L 10=L 1×N 1×N 2×N 3,L 20=L 2×N 1×N 2×N 3
进一步,服务器中设置有危险源安全监视距离L 0,其中L 0>L 1
当施工人员与危险源之间的距离达到L 0时,服务器将施工人员标记为重点监控人员,提高距离采集频率和精度,并判定该施工人员与危险源之间的距离是否小于等于L 10、L 20
进一步,服务器中设置有施工人员行走路径,当施工人员被标记为重点监控人员后,通过临近采集的数据,判定该施工人员行走方向,若该施工人员行走方向或路径并非朝向所述危险源时,将该施工人员由重点监控人员修改为普通施工人员,对于普通人员不计算L 10、L 20。。
进一步,若该施工人员行走方向或路径朝向所述危险源时,判定是否在b秒内进入危险源L 1范围内,如果该施工人员行走方向和路径虽然朝向所述危险源,但在b秒不会进入危险源L 1范围内,也将该施工人员由重点监控人员标记为普通施工人员。
进一步,施工人员行走路径根据施工环境预设,或者通过服务器采集的路径点进行DBSCAN聚类后形成。
进一步,一级预警信息或二级预警信息触发后,服务器自动跟踪并记录施工人员后续路径,直至警报解除或离开危险源辐射的区域;
如预警信号发出后服务器智能识别该行为逐渐临近危险源时,服务器将发送信号及时通知安全管理人员。
进一步,警报装置为施工人员佩戴的手机或其它具备震动或声音提示的设备;
一级预警信息为间隔振动提醒,二级预警信息为持续振动。
进一步,危险源处设置有声光报警装置,当服务器判定施工人员处于危险源L 20范围内时,控制声光报警装置发出声光报警。
进一步,危险源危险等级的降低或消除需要两个安全管理人员同时作出指令;
当服务器接收到的一名施工人员针对一处危险源降低危险等级或消除危险源的操作时,判断是否有另一名施工人员针对同一处危险源作出相同操作,若是,则降低危险等级或消除危险源。
进一步,当服务器接收到的一名施工人员新增危险源或增加危险源危险等级时,服务器执行相应操作。
本发明由于采用以上技术方案,使之与现有技术相比,具有以下的优点和积极效果:本申请所述的方法通过设置二级预警,并考虑危险源种类、不同气候条件、人员因素等影响,分别设定安全因子N 1、N 2、N 3,从而计算出预警触发实际距离L 10、L 20,通过采集施工人员的位置信息,计算与危险源之间的实际距离,并判定实际距离与L 10、L 20之间的关系,从而使报警信息更加与施工现场具体安全情形相一致,能有效避免现场各类伤亡事故和质量事故的发生。所述方法还能够灵活增加或消除危险源及更改危险源危险等级,使得判定结果更贴近实际情况。所述方法通过设置危险源安全监视距离L 0,当施工人员与危险源之间的距离达到L 0时,将施工人员标记为重点监控人员,提高距离采集频率和精度。
附图说明
图1为本发明中的用于施工现场人员安全预警的方法的流程框图。
具体实施方式
以下结合附图和具体实施例对本发明提供的一种用于施工现场人员安全预警的方法作进一步详细说明。结合下面说明,本发明的优点和特征将更清楚。需说明的是,附图均采用非常简化的形式且均使用非精准的比例,仅用以方便、明晰地辅助说明本发明实施例的目的。
实施例一
我们知道,事故的危害性与危险源的危险级别相关,因此,必须对危险源的危险级别加以区分。我们将危险源分为三级:一级危险源触发的事故发生则大概率造成人员死亡事件,或直接经济损失极大,或对社会造成极大恶劣影响,比如未封闭且无法及时封闭的临边洞口;二级危险源触发的事故发生则大概率造成人员受伤事件且小概率发生人员死亡概率,造成的经济损失严重,或对社会可能造成不良的影响的事故,比如高处临时悬挂未安装牢固的材料或设备以及施工现场可能发生触电、中毒、烫伤、刺伤危险的区域;三级危险源触发的事故不会造成人员伤亡,但会导致一定的经济损失,产生的社会不利影响极小,比如施工现场未干的油漆区域。
申请人发现,环境的变化会影响安全事故发生的概率,比如大风、暴雨、大雾等天气,如遇到未及时封闭的洞口,会使跌落的概率增加。申请人还发现,个人因素的差异也会影响安全事故的发生,比如施工人员年龄、性别、视力、反应能力等。
本申请采用两级预警的模式,当施工人员与危险源之间的距离达到实际触发预警的距离L 10、L 20,分别发出一级预警、二级预警。实际触发预警的距离L 10、L 20,是在预设的一级安全距离L 1和二级安全距离L 2的基础上通过设危险源安全因子N 1、人员安全因子N 2、环境安全因子N 3加以调整。为了避免事故的发生,提高预警能力,本申请还设置有危险源安全监视距离L 0,当施工人员与危险源之间的距离达到危险源安全监视距离L 0时,将施工人员标记为重点监控人员,可以提高距离采集频率和精度。由于采集频率和精度的提高,会增加设备能耗,会增加存储的数据量,加大计算机运算量,而通过将施工人员区分为普通施工人员和重点监控人员,对普通施工人员采用较低的距离采集频 率,可以降低设备能耗,降低采集数据量,并提高数有效据处理的速度。
如图1所示,本实施例提供的一种用于施工现场人员安全预警的方法,包括:
服务器中预设一级安全距离L 1和二级安全距离L 2,其中L 1>L 2
在电子地图中标识出危险源,设定危险源等级,并根据危险源具体情况设定危险源安全因子N 1;采集施工人员的信息,并针对施工人员分别设定人员安全因子N 2;根据环境变化,设定环境安全因子N 3
佩戴有定位装置的施工人员进入施工现场后,施工现场中设置有与定位装置匹配的位置采集装置,位置采集装置采集施工人员的位置并上传至服务器;
服务器中设置一级预警实际触发距离L 10、二级预警实际触发距离L 20的计算公式,服务器计算与最近危险源的距离是否小于等于L 10,若是服务器则控制施工现场的警报装置发出一级预警信息,并计算与最近危险源的距离是否小于等于L 20,若是服务器则控制施工现场的警报装置发出二级预警信息;其中,L 10=L 1×N 1×N 2×N 3,L 20=L 2×N 1×N 2×N 3
需要说明的是,危险源安全因子N 1与危险源等级相对应,比如一级危险源、二级危险源、三级危险源对应的N 1分别为a 1、a 2、a 3,a 1、a 2、a 3为预设值,a 1>a 2>a 3,比如a 1=1.2、a 2=1.1、a 3=1。对于同一安全等级的危险源,还可以根据危险源的具体情形,进一步进行调整。比如同为二级危险源,一个的N 1=1.1,另一个根据安全员具体情形不同,设置为N 1=1.11。
需要说明的是,在施工作业人员和管理人员初进入工地前,安全管理员会根据具体人员的年龄、反映能力、辨别能力、行动能力和是否有违规记录等因素,个性化的针对每一个人设置人员安全因子N 2,比如N 2数值范围设定为1~1.1,当然,取值范围可根据需要进行设定。
需要说明的是,环境安全因子N 3,可根据实际环境情况进行设定。服务器可采集施工现场当地气象局发出的实时气候(主要为天气状态及风力等级)精准预测,并结合现场光照、湿度、具体时间段,由管理人员设定环境安全因子N 3,管理人员设定环境安全因子N 3时,可将不同的施工区域、不同的施工 高度对环境安全因子N 3的数值进行调整。作为举例,环境安全因子N 3的数值数值范围为1~1.2。
需要说明的是,本申请中采用定位装置和位置采集装置对施工人员进行定位,当位于室内时,可采用UWB定位技术、蓝牙定位技术或红外定位技术等方式进行,需要注意的是,室内的柱子、墙、梁等土建将会导致UWB、蓝牙、RFID定位精度下降,位置采集装置的布设时需要避免出现精度下降较大的情形;还需要注意蓝牙、红外定位的时钟同步性,以提升其定位精度。当位于室外时,可以用北斗或GPS定位,该定位技术拥有亚米级甚至厘米级定位精度,并且成本较低。
具体方式不做限定,只要能实现对施工人员位置采集即可。比如施工人员佩戴有定位芯片的可穿戴设备(安全帽、手环)或卡片,施工场地分布若干信号采集装置,采集与定位芯片之间的距离。
需要说明的是,警报装置可以为施工人员佩戴的手机或其它具备震动或声音提示的设备。作为举例,一级预警信息可为间隔振动提醒,其振动频率可设置为1秒/次,此类预警信息人员及时停止行走,观测并辨别周围危险源;二级预警信息可为持续振动,提示施工人员危险源离人体非常近,必须停止行走并及时观察。各施工现场亦可根据实际需要在服务器中设置提示因素,比如危险源种类、与危险源的距离,也可以设置报警种类,如提示现场人员远离未干的油漆区域。
需要说明的是,本申请设置有危险源安全监视距离L 0,其中L 0>L 1>L 2;当施工人员与危险源之间的距离达到危险源安全监视距离L 0时,将施工人员标记为重点监控人员,提高距离采集频率和精度。然而,如果施工人员虽然在危险源安全监视距离L 0的范围内,然而行走方向和/或路径并不是朝向危险源,此时该施工人员并非需要的重点监控人员,如果标记为普通施工人员,将更加节能并降低采集、存储的无效数据数量。进一步,服务器中设置有施工人员行走路径,当施工人员被标记为重点监控人员后,通过临近采集的数据,判定施工人员行走方向,若该施工人员行走方向或路径并非朝向所述危险源时,将该 施工人员修改为普通施工人员。还可以根据该施工人员的行走方向和路径,判定是否在b秒内进入危险源L 1范围内,如果该施工人员行走方向和路径虽然朝向所述危险源,但行走速度很慢,在b秒不会进入危险源L 1范围内,也可暂时将该施工人员标记为普通施工人员。作为举例b=10s。路径的设置,可以采用根据施工环境预设,也可以根据采集的路径点进行DBSCAN聚类后形成行走路径。
为了便于及时发现现场各类危险情况做出通报,也便于今后事故的溯源和记录,各类警报一旦触发,服务器自动跟踪并记录后续路径,直至警报解除或离开危险源辐射的区域。如预警信号发出后服务器智能识别该行为有进一步扩大至警报级别时,可将这一信息及时通知安全管理人员;同时,危险源上方可悬挂警示装置,一旦该类情况发生或达到警报级别,处于危险源附近的警报装置由服务器提供信号而产生预警,以起到进一步提醒的作用。
进一步的,由于现场对危险源是处于不断整改和修复过程中的,因此现场安全管理员应根据每日早上巡查的现场情况考虑现场各类危险源调整,为了降低人为操作的误差,应由另一名有权限的人员确认后,在计算机对危险源修改等级指令确认达到“与”逻辑后,在服务器中可实现危险源的消项或危险等级的降低。若危险源等级升高,仅一名安全管理员上传即可临时修改,进一步,服务器还同时通知至少一名其他安全管理人员在时间T内进行确认,若在时间T内未收到确认信息,则恢复至修改前设置,只要有一名安全管理人员确认,即确认该修改信息。
实施例二
举例一:施工工程为上海的某超高层建筑,冬日某日清晨8时,气候小雨,幕墙工程从下往上封闭至50层,经过安全管理员赵某和安全监理李某巡视后,由于设计变更,在115层西北向靠近核心筒处由于设计变更开设了一个尺寸为1m×0.5m的临时洞口,现场缺乏洞口的临时围挡,只能通过木质板对洞口临时覆盖,盖板上方安装一警铃,间断闪烁红光,该洞口用于安装空调风管,贯 穿10层,纵深35m左右,经分析应定义为一级危险源,现场安全监理对该危险源通过审核,危险源安全因子N 1=1.2。根据当天浦东地区官方播报的气象参数,当天的湿度为62%左右,官方提供的气候为小雨转晴,微风;经现场实探,安全管理员现场设置的实时气候参数小雨,风力中等,湿度73%左右,管理人员设定环境安全因子N 3为1.13。该层在这天需要进行管道安装作业,劳务作业人员王某,年龄24岁,无特殊职业病,视力和听力良好,自2年前进入工地后受过安全教育并每次安全考评均优秀,人员安全因子N 2=1;现场设定二级报警预警,一级初始触发为L 1=10m,二级初始触发L 2=3m。王某在离开核心筒施工电梯进入115层后,现场经过采集位置信息,服务器判定王某正向危险源靠近,当王某进入洞口附近的危险预警触发范围内,即王某进入以洞口为圆心,以L 10=L 1×N 1×N 2×N 3=10×1.2×1×1.13=13.56m为半径的范围内,经服务器自动判别可能出现高处坠落事故后,自动发送危险源预警信号至王某佩带的胸牌和智能手机上,此时王某由于手机关机,而冬日衣服较厚未感知预警信号的发生,继续向危险源方向前进。当王某进入以洞口为圆心,L 20=L 2×N 1×N 2×N 3=3×1.2×1×1.13=4.07m为半径的范围内时,服务器判定后发出警报,同时经过服务器发出的指令并同步抄送赵某,同步的,胸卡由之前的间断振动变为持续振动,并触发盖板上警铃的声光报警,同时反馈至安全管理员。在安全员赵某通过对讲机制止王某行动的同时,王某也通过盖板上的警铃发现了危险源位置,做出了及时驻足的行为,避免了可能发生的安全事故。王某打开手机,手机APP上马上通过语音播报显示此时危险源的位置和警示级别,王某通过手机操作消除了警报,服务器发出是否重复提醒该危险源的选项,王某在手机上操作取消该服务。
举例二:同日上午10时,天气转晴,115层风力减小为微风状态,安全管理员赵某和监理安全员李某再次巡视工地时发现实施例一中未封闭的洞口危险源得到了整改,两人在手机管理端对该危险源进行了消项处理,服务器接到两人一致的信号后,该危险源自动消除。此后李某离开施工现场,赵某继续巡视后发现在45层设备兼避难层东北角靠幕墙位置,有一个小型悬吊式风机 正处于安装阶段,但由于工具和辅材的缺乏,该风机暂时由手拉葫芦悬吊至2m高度后,待3日后安装,赵某发现该处可能会导致主动打击或被动打击,故在手机端经过精确定位定义此项为二级危险源,服务器识别后,此时平台自动将此位置转换成二类危险源,其危险源安全因子N 1=1.1。此时由于环境因素较实施例一有所改观,且由于幕墙封闭的作用施工现场无风,故此时该楼层环境安全因子设定为N 3=1.05。在服务器预设的对于二级危险源同样有2类预警和警报提示,其中L 1=8m,L 2=2m。1小时后,项目管理部的资料员陈某(女,49岁,重度近视,轻微残疾,人员安全因子N 2=1.17)需要经过该区域,当她处于该危险源半径范围L 10=10.81m时,服务器判定发出二级危险源预警,陈某及时发现手机APP端的振动和胸卡振动提醒,并根据语音提示识别危险源后,在手机端确认危险源,并选择了不需要重复提醒,警报解除。
举例三:次日,该工地地下二层车库某一区域浇筑环氧地坪,在施工完成后由于地面油漆未干应防止人员进入,但现场门禁损坏,经过赵某和李某共同确认后可能此区域会发生人员误闯,导致油漆被破坏,故此处为三类危险源,在平台中设置警示范围L 1=4m,而三类危险源由于不影响现场人员的生命财产安全,危险源安全因子可设置为1,由于危险性低、经济损失小,其它安全因子也可以设置为1。当现场人员处于该区域周边4m范围内时,平台发出预警信号。当天由于在此处安排了安保巡查,又在附近树立了相应的警示牌,故未发生预警事件。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
