摘　　要：2017年9月长汀地震台安装了VP宽频带倾斜仪,从这几年的运行情况来看,该仪器自动化程度、观测精度较高,能够为地震分析预报提供比较可靠的观测数据,但其稳定性较差,如:VP宽频带倾斜仪输出零漂较严重,常常需要调零,虽增加了自动调零装置,可通过网络实现远程调零功能,避免因人员进洞对仪器产生干扰,但调零模块经常出现故障,不是电机过载,就是芯片烧坏。本文通过对VP宽频带倾斜仪在日常观测中常见故障进行分析,寻找解决仪器故障的方法,并对VP宽频带倾斜仪日常维修进行总结,以备在今后的观测过程中快速判断仪器故障原因,及时完成仪器维修,确保资料连续可靠。In September 2017,Changting seismic station installed VP broadband tiltmeter.From its operation in recent years,the instrument has a high degree of automation and observation accuracy,which can provide more reliable observation data for earthquake analysis and forecast.However,its stability is poor.The output zero drift of VP broadband tiltmeter is serious,which often need to zero.Although the automatic zero device has been added,which can achieve remote zero function through the network to avoid interference with the instrument due to personnel entering the hole,the zero module often failure including motor overload,chip burn out.In this paper,the common faults of the VP broadband tiltmeter in daily observation were analyzed to seek solutions to instrument failure,and summarize the VP broadband tiltmeter daily maintenance.We can quickly determine the cause of the instrument failure,timely complete the instrument maintenance,ensure continuous and reliable data in the future similar problems in the observation process.
