基于精确人员定位的煤矿放炮监控系统设计

Design of coal mine blasting monitoring system based on accurate personnel positioning

针对现有煤矿放炮监控系统无法精确监测放炮区域人员位置,易存在误检、漏检放炮区域人员的问题,设计了一种基于精确人员定位的煤矿放炮监控系统。该系统利用具备精确人员定位功能的动态目标识别器监测放炮区域人员位置分布及身份信息,并结合放炮区域瓦斯浓度,判断放炮区域是否符合班组长、放炮员、瓦斯巡检员均在放炮警戒点附近,放炮区域无人员,瓦斯浓度未超限的安全放炮条件;当符合安全放炮条件时,解锁无线发爆器进行放炮作业,否则将无线发爆器置于闭锁状态。现场应用结果验证了该系统的有效性。

In view of problem that existing coal mine blasting monitoring system could not accurately monitor position of personnel in blasting area,and it was easy to cause false detection and missed detection of personnel in blasting area,a coal mine blasting monitoring system based on accurate personnel positioning was designed.The system monitors position distribution and identity information of personnel in blasting area by use of dynamic target recognizer with accurate personnel positioning function.Combining with gas concentration in blasting area,it judges whether the blasting area meets safe blasting conditions such as group leader,blasting member and gas inspector are all near blasting warning point,no personnel in the blasting area and gas concentration do not exceed limit.When the safe blasting conditions are met,wireless exploder is unlocked for blasting operation,otherwise it is set in locked state.The field application results verify effectiveness of the system.
