Abstract:Due to the instability of the work performance of DPZ1 integrated hardware controller,the integrated meteorological observation service software ISOS cannot collect meteorological observation data normally,which will affect the uploading of the observation data of the station.Through the joint efforts of station operators and equipment support personnel,repeated observation tests are conducted.The faults are caused because of the poor performance of the built-in network card of the DPZ1 integrated hardware controller,which has resulted in the unstable performance of the integrated hardware controller.After the replacement of the relevant equipment,the problems that had been troubling the station observation personnel for a long time are solved by troubleshooting.
