Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] This circuit is now applied on radar with PND (Portable Navigation Devices, portable automatic navigation system). In the past, radar was equipped with PND. In order to adapt to different schemes, different connecting lines are needed to adapt, which brings great benefits to production and users. It saves a lot of inconvenience, and can also be applied to PND with various serial port peripherals.

[0023] refer to Figure 2-7 , the adaptation circuit includes: a main control module, a first electronic switch connected to the main control module, a second electronic switch, the second electr...

Abstract

The invention, which is suitable for the field of electronic circuits, provides a simplex-duplex automatic adapted circuit and a system of portable navigation devices. The adapted circuit comprises a master control module, and a first electronic switch and a second electronic switch which are connected with the master control module, wherein, the second electronic switch is connected with a USB interface module, and the USB interface module is connected with a power-supply control module. According to the invention, the self-adaptation of different serial communication interfaces of portable navigation devices is solved, an effective method for connecting external serial devices with portable navigation devices is provided, thus the problem of adaptive line waste caused by using traditional methods is reduced.

Description

technical field [0001] The invention belongs to the field of electronic circuits, in particular to a single-duplex automatic adaptation circuit of a portable automatic navigation system and a corresponding portable automatic navigation system. Background technique [0002] With the opening of the US military's Global Positioning System (GPS) for civilian use, products that use satellites to position and navigate cars are not uncommon. Satellite positioning and navigation equipment was "passive" at the earliest time. To be precise, it can only be regarded as a satellite positioning system. It can only let others know the position of the receiver holder through the GPS receiver. Some satellite navigation products that appeared later are "active". This type of satellite navigation product is actively seeking "how to get there" while knowing its position. However, these products are not well integrated with life and mobile. Together, the portable automatic navigation system (PN...
