| Abstract: | The wide application of STP-yh system effectively ensures the on-site safety of shunting operation.However,with the increase of service life year by year,the pressures of operation and maintenance are becoming increasingly prominent.By analyzing the electromagnetic wave transmission loss of each component of wireless channel of STP-yh system,using the typical Hata-Okumura model curve method,combining with the specific situation in the actual maintenance,the main factors of wireless signal interruption are summarized,which provides theoretical guidance and maintenance technical requirements for the on-site equipment management department in the fault handling of wireless signal interruption. |
