Device for detecting buckling of radio frequency line

Abstract

The invention relates to the technical field of radio frequency antennas, and discloses a device for detecting the buckling of a radio frequency line, and the device comprises a plurality of detection assemblies which are sequentially connected in series. Each detection assembly in the plurality of detection assemblies comprises two radio frequency seats, and a radio frequency line is connected between the two radio frequency seats; the pin of the radio frequency seat at one end of the first detection assembly in the plurality of detection assemblies is a GPIO signal connection point, and the pin of the radio frequency seat at one end of the second detection assembly in the plurality of detection assemblies is used for grounding. During detection, if each radio frequency line is well buckled, GPIO signals can form a complete loop through a plurality of radio frequency lines which are connected in series, and at the moment, GPIO is in a low level; if any one or more radio frequency lines are buckled badly, the GPIO cannot form a loop, and the state of the GPIO is a default setting state (high level or high resistance state).

Description

technical field [0001] The invention relates to the technical field of radio frequency antennas, in particular to a device for detecting buckling of radio frequency lines. Background technique [0002] In the wireless terminal design, the design scheme of the main board and the sub-board is adopted, and the radio frequency signals of the main board and the sub-board are connected through radio frequency lines. [0003] In order to ensure the reliable transmission of RF signals between the main board and the sub-board, a radio frequency line buckle detection circuit will be designed. The principle of the radio frequency line detection circuit currently used is: add GPIO (general-purpose output / Input General-purpose input / output) detection signal to detect the buckling state of the RF line. [0004] However, if there are multiple RF channels between the main board and the daughter board, multiple RF wire connections are required, so multiple GPIO connection points are requir...

Problems solved by technology

The disadvantage of this design method is that multiple GPIO interfaces are required in the case of multiple RF lines, which increases the difficulty of wiring the printed circuit board. At the same time, the software needs to detect the status of multiple GPIO connection points, which increases the detection cost and reduces the software cost. operation efficiency
