Abstract
The invention relates to a power supply switch controller for a GPS receiver. Wherein, the power on/off state of a GPS receiver can be determined depending on whether the GPS receiver is moved. The power supply switch controller essentially comprises a position sensor (for example a gyrometer or a digital compass) and a power supply controlling module. After the position sensor provides any info on position, the power supply controlling module will determine the on/off of the power supply for the GPS receiver depending on the change in the info on position. In this way, so long that the position is not changed, and the GPS receiver is not moving, then it is not necessary to receive any positioning info, so the power supply of the GPS receiver can be switched off temporarily.

Hence one can see that, and bluetooth module 12 is not set up when online with the locating information analyzer as yet, and bluetooth module 12 does not need to transmit locating information.Since need not transmit locating information, bluetooth module 12 just these locating information have not been needed certainly yet.Since need not obtain locating information, can provide the gps receiver 14 of locating information just can be closed fully.So do not set up when online as yet when bluetooth module 12, be actually the power supply that to cut off gps receiver 14, but can not be closed fully because bluetooth module 12 still need wait for online requirement at any time with the locating information analyzer.
In a word, along with the short and small frivolous designer trends of electronic product, the satnav receiver also must be tried every possible means and be allowed its volume is littler, weight is lighter.But take the battery of many spaces and weight, according to present technical level, also can not reduce volume can significantly improve its charge capacity again in short time, so having only, each tame manufacturer tries every possible means to reduce satnav receiver power consumption, to avoid being forced to adopt the battery that volume is big, charge capacity is big.
See also Fig. 2, Fig. 2 is the synoptic diagram of another known satnav receiver.As shown in Figure 2, known satnav receiver 30 still mainly is made up of gps receiver 34 and bluetooth module 32, but in order to reach known power saving design, make into especially only bluetooth module 32 to be powered, and change by powering through 16 pairs of gps receivers of transmission line 34, changing whether gps receiver 34 is transmitted power supplys by switch 18 decisions.
The power saving design of known satnav receiver 30 mainly be according to the online mode between bluetooth module 32 and the locating information analyzer (not describing), and whether decision is to gps receiver 34 power supplies.Particularly, if online mode, is not powered to gps receiver 34 by switch 18 when online for setting up.Otherwise, if online mode, is just powered to gps receiver 34 when online for setting up.Thus, only if necessary (be on line state, may have needed to transmit locating information at any time and give the location information analyser) just to gps receiver 34 power supplies, and then saved unnecessary power consumption.
Except being decided the opportunity of cutting off the electricity supply by the online mode between bluetooth module 32 and the locating information analyzer, the PDA or the situation of movement of vehicle that load gps receiver 34 also can be used to determine powering mode.Specifically, if load the PDA of gps receiver 34 or vehicle when not mobile, gps receiver 34 received locating information must not have anything to change, since when not mobile and when not changing, that is temporary close gps receiver 34 certainly, and reaches power saving effect equally.
