A mobile terminal and a method are provided for power saving. The mobile terminal monitors changes of data on a UART bus, acquires current operating states of a Bluetooth chip and a main control chip on the mobile terminal, and when detecting that there is no data on the UART bus, the main control chip controls a Bluetooth module to enter into a power saving mode. By adopting the technical scheme described, once it is detected that there is no data on the bus, the Bluetooth module will be enabled to enter into a state of power saving mode immediately, which ensures that the Bluetooth module is always in the state of power saving mode when there is no service ongoing, thereby increasing the standby time of the mobile terminal to the maximum extent, and improving the level of the user experience.

Mobile terminal and power saving method thereof

A method for vertically grounding and leading down form an inner side of a composite pole tower and pole tower thereof, wherein the method includes the following steps: extending an upper metal cross arm from an extended line of at least one side of a ground wire cross arm which is made of metal, vertically leading down a ground down-leading wire from a distal end of the upper metal cross arm, connecting the ground down-leading wire to the pole tower via a lower metal cross arm at a distance under a lower lead, and grounding the ground down-leading wire along a tower body of the pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is selectively directly connected to the metal pipe via the lower metal cross arm. The upper metal cross arm and the lower cross arm are able to provide a distance between the ground down-leading wire and the pole tower. The method enhances the ability of bearing lightning flashover, increases the insulating intensity to lightning impact, and prevents burning to composite insulator by power-flow current after lightning flash over. And also the method is easy and simple for application.

A method for vertically grounding and leading down form an outer side of a composite pole tower and pole tower thereof, wherein the method includes the following steps: extending an upper metal cross arm from an extended line of at least one side of a ground wire cross arm, vertically leading down a ground down-leading wire from a distal end of the upper metal cross arm, connecting the ground down-leading wire to the pole tower via a lower metal cross arm at a distance under a lower lead, and grounding the ground down-leading wire along a tower body of the pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is selectively directly connected to the metal pipe via the lower metal cross arm. The method facilitates in compressing the width of the transmission corridor to a maximum extent as well as designing a lightning protection, preventing the ground down-leading wire from short-circuiting with the tower body, and realizing the insulation function of the composite material tower body. The manner of using unilateral ground down-leading wire saves material, and is economical and simple in structure.
