Problems solved by technology

Although this method can reduce power consumption, its effect is still limited. After all, using a series of voice calls also consumes a lot of power. If the voice can be replaced with simple sound effects, the power consumption will be minimized

Embodiment Construction

[0033] figure 1 It is a structural diagram of a navigation device with a power saving mechanism according to an embodiment of the present invention. exist figure 1 Among them, the navigation device 100 with power saving mechanism includes a global positioning receiver 110 , a first processing unit 120 , a second processing unit 130 and a sound playing unit 140 . Wherein, the GPS receiver 110 is coupled to the first processing unit 120 and the second processing unit 130 , and the second processing unit 130 is coupled to the sound playing unit 140 .

[0034] Before describing the overall operation, it should be understood that the navigation device 100 with the power saving mechanism is a navigation device that can switch the working mechanism. Here, the navigation device 100 uses the first processing unit 120 to perform the switching action, that is to say, when the first processing unit 120 is in the first mode, the navigation device 100 will enter the normal working mechani...

Abstract

The invention relates to a navigation device with a power saving mechanism and a method thereof. The navigation device comprises a GPS receiver, a first processing unit, a second processing unit and a sound playing unit. The GPS receiver is used for receiving satellite signals of the GPS and producing longitude and latitude information. The first processing unit switches a first mode to a second mode according to a control signal, and is in a forbidden energy state after being switched. The second processing unit compares the longitude and latitude information with destination information for producing direction information and distance information when in a habilitation state. The sound playing unit selects two frequencies from a plurality of navigation frequencies according to the direction information and distance information and plays monophony signals formed by the two frequencies in sequence.

Description

technical field [0001] The present invention relates to a navigation device and its navigation method, and in particular to a navigation device with a power saving mechanism and its navigation method. Background technique [0002] GPS Satellite Vehicle Guidance System (Automatic Vehicle Guidance System, AVGS) is to use GPS technology, set the receiving antenna on the car, and combine the GIS database in the car, so that the screen in the car can display navigation data as a driving guide. Orientation guidance when driving. In addition, the driver can also choose the driving route to reach the destination quickly. [0003] However, the above-mentioned GPS satellite car automatic navigation system is built on the car, which will greatly increase the manufacturing cost of the car, and jointly increase the economic burden of consumers when buying a car. Therefore, in view of this shortcoming, a portable GPS navigation device with smaller volume and lower price has been develop...
