【中国梦实践者】李宝昌:通信领域行家里手 几十载磨砺技术尖兵

2017-09-07 16:27:12   国际在线

 药到病除的救火队员

作为民航专家库其中的一员,李宝昌的技术能力在行业里是出了名的。这几年一直扮演着华北地区地空通信设备救火队员的角色,当设备遇到疑难问题,甚至连厂家也拿不出解决办法的时候就把他请过去,排故率达到了百分之百。

2015年底至2016年初,由于频率重新配置,内蒙古蛮汉山甚高频台的一个频率出现了奇怪的现象,在某位置前后10km左右的范围内,管制接收信号时有断续,机组接收正常。技术人员长时间跟踪记录和分析了各种飞机状态的信号质量,又请设备厂家现场进行了指标的测试工作,基本排除外界干扰和设备的因素,但仍然不能确定原因。这时候,大家想到了李宝昌。

在研讨一个下午的信息和细节后,他判断,设备运行正常,问题可能出在地形地貌导致的多路径反射上。第二天,他们上了蛮汉山雷达站,依靠多年的经验,他和同事对天线位置进行了改动,问题就此解决。

不管是判断故障原因,还是找到解决方法,靠的都是过硬的理论知识和丰富的经验,以及不放过每一个细节的“强迫症”。

2016年的冬季,天津甚高频台站频率串扰严重。他带领技术人员赶赴现场,在听取了技术报告后,其他技术人员逐步逐节点对设备进行检查,正当大家对此一筹莫展的时候,只见他蹲下身躯,在天馈系统的避雷器附件上摸着什么,就在大家充满疑惑的看着他时,却从他的脸上看到一丝笑意,大家知道这下有戏了,问题找到了。

“当时我摸着那个避雷器,就觉得不对劲,因为它是热的,可按常理来说肯定是不热的,说明这个地方有大的电流通过,所以才是热的。”经过检查,问题就出在了这个避雷器上,由于避雷器遭到雷击损坏,已经短路,发射时造成了信号的泄露,最终造成了频率的串扰。

从呼伦贝尔到河北再到郑州,李宝昌的身影无处不在,他被称为“救火队员”,用他的话来就是“每次都不白跑”,这是他自豪的。

 授之以渔的老师父

“李老师对我们是知无不言,言无不尽,绝对的有问必答,毫无保留。而且很多时候他教我们东西,不是告诉你怎么做就完了,而是要把整个原理都告诉你。”于品杰说。

同事们经常看见李宝昌在办公室里给年轻人“开小灶”。对待年轻人,他像对待自己的孩子一样,做的不好的地方就批评,生怕留下坏毛病。

“他对我们都很呵护,像个老师父一样,完全没有官架子。但是也很严格,不仅要完成工作还要做好工作。”朱琦说。

对年轻人的培养,李宝昌有自己的一套经验。“你如果说今天咱们来上上课,他们会反感,他们不喜欢说教啊、考试啊。我一般就是跟他们聊天,用讲故事的方式,把我这些年排除故障的经验讲给他们听。”

还有两年就退休的李宝昌很想把一肚子的经验都传授给年轻人,他说这个技术也没有多难,就是入门比较困难,我能教的就多教点。(素材来源:华北空管局党委 吕思敏 于品杰)
