Abstract

The invention provides a circuit channel gating control method and device, and a vehicle-mounted navigation positioning system. The method is applied to vehicle-mounted navigation and positioning equipment, and the vehicle-mounted navigation and positioning equipment at least comprises an active antenna circuit channel and a passive antenna circuit channel. The method comprises the following steps: detecting whether an insertion signal of an active positioning antenna exists in the vehicle-mounted navigation positioning equipment or not; under the condition that the insertion signal of the active positioning antenna is not detected, outputting a low-level switch control signal; disconnecting the output of the power supply module according to the low-level switch control signal, and gating the input of the positioning module to the passive antenna circuit channel; under the condition that the insertion signal of the active positioning antenna is detected, outputting a high-level switch control signal; and closing and conducting the power supply module according to the low-level switch control signal, and gating the input of the positioning module to the active antenna circuit channel. By adopting the method disclosed by the invention, the use is more convenient, and the robustness of receiving the positioning signal of the vehicle-mounted navigation positioning equipment is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle-mounted multimedia, in particular to a gate control method and device for a circuit channel, and a vehicle-mounted navigation and positioning system; in addition, it also relates to an electronic device and a non-transient computer-readable storage medium. Background technique [0002] In recent years, with the rapid development of communication technology, various positioning and navigation technologies have become more and more mature, and are widely used in multimedia devices such as mobile phones and vehicles. In particular, in order to ensure safe driving on the vehicle multimedia device (vehicle machine), its positioning and navigation function has become an indispensable part of the vehicle machine, and is widely used in navigation and positioning scenarios. [0003] At present, due to different factors such as the installation environment of the existing vehicle-mounted multimedia ...
