AI Technical Summary

Problems solved by technology

However, when the current Bluetooth GPS receiver 100 is used, the power supply of the signal receiving unit 110 must be manually turned on or off or the working mode of the signal receiving unit 110 must be switched.
Regardless of whether the Bluetooth transmission interface is connected to the corresponding wireless communication device 130 or not, the signal receiving unit 110 is in the normal working mode, which will cause waste of power for the signal receiving unit 110
[0004] Moreover, because it must be manually operated every time it is used, it causes a waste of manpower and cannot give full play to the wireless application spirit of the GPS receiver 100
If the user forgets to turn off the power or touches the switch by mistake when the GPS receiver 100 is not in use, it will cause improper waste of system power due to misoperation, and even damage some components due to excessive discharge.

Embodiment Construction

[0011] Please refer to FIG. 2 , which shows a block diagram of a GPS receiving device according to a preferred embodiment of the present invention. The GPS receiving device 200 includes a signal receiving unit 210 and a wireless transmission interface 220, and the signal receiving unit 210 is used for receiving and outputting a GPS data signal Sd, such as position and satellite-related information. The wireless transmission interface 220 is, for example, a bluetooth transmission interface, coupled to the signal receiving unit 210 for transmitting the GPS data signal Sd to the wireless communication device 230 used with the GPS receiving device 200 . The wireless communication device 230 is, for example, a mobile phone or a vehicle-used PDA.

[0012] The signal receiving unit 210 includes a power device 212 for providing power required for the operation of the signal receiving unit 210 . Before the wireless communication device 230 is connected with the GPS receiving device 20...

Abstract

The invention relates to a GPS receiving device wireless communication device that includes signal receiving unit and wireless transferring interface. The signal receiving unit is used to receive and output GPS data signal. The wireless transferring interface connects to signal receiving unit and transfers GPS data to wireless communication device. Before wireless communication device connecting to GPS receiving device, the signal receiving unit is in energy saving mode. After connecting, the signal receiving unit begins normal working state to output GPS data.

Description

technical field [0001] The present invention relates to a GPS receiving device and its signal transmission method, and in particular to a GPS receiving device which enters a normal working mode when it is connected with a wireless communication device and its signal transmission method. Background technique [0002] In recent years, due to the increasing demand for short-distance wireless communication applications, wireless Internet will be an important trend in the future. For example, the Bluetooth technology is a brand-new network architecture, which belongs to a small-scale radio communication network, which is not restricted by any direction and can penetrate obstacles for one-to-many short-distance transmission. At present, the most potential application is the combination with a Global Position System (GPS) receiver, such as a Bluetooth GPS receiver, which is then matched with various corresponding wireless communication devices to transmit positioning related inform...
