Fig. 6 is a kind of flow chart of the method for transmitting signals shown according to another exemplary embodiment, the signal transmission side
Method is applied in locator as shown in Figure 2 or Figure 3, as shown in fig. 6, the method for transmitting signals includes the following steps.
In step 601, when low-power consumption bluetooth component includes processor, RF switch is controlled by processor and is in the
Two-state.
Before locator sends position signal to terminal, locator needs to establish bluetooth connection with terminal.Due to positioning
Device and terminal are matched when establishing bluetooth connection, and both need reception signal with clock synchronization locator, it is also desirable to send letter
Number, at this point, processor, which can control RF switch, is in the second state, i.e., bluetooth connection is established by alternate path and terminal.
In step 602, bluetooth connection is established by low-power consumption bluetooth component and terminal.
Wherein, the low-power consumption bluetooth component in locator carries out pairing with the low-power consumption bluetooth component in terminal and resume is blue
The technology of tooth connection is highly developed, does not repeat herein.
In step 603, RF switch is controlled by processor and first state is switched to by the second state.
After locator and terminal establish bluetooth connection, processor can control RF switch and is switched to by the second state
First state, to send position signal to terminal by the first access.
Since the power consumption of the power amplifier in the first access is higher, processor can also need not send position
RF switch is controlled when confidence and is in the second state, and when needing to send position signal, control RF switch is cut by the second state
It is changed to first state, to reduce power consumption.
Wherein, RF switch is controlled by processor and first state is switched to by the second state, including：

It is whether identical, when current position signal and prior location signal difference, determine that position signal meets transmission conditions；
2) when signal component output is positioning component, the position that current position signal and terminal are calculated by processor is believed
Second distance between the first distance between number and prior location signal and the position signal of terminal, whether the first distance of detection
Determine that position signal meets transmission conditions, the position signal of terminal when the first distance is more than second distance more than second distance
It is that processor is got before control RF switch is switched to first state by the second state；
3) when signal component output is acceleration transducer, whether it is more than by the numerical value of processor test position signal
Predetermined threshold determines that position signal meets transmission conditions when the numerical value of position signal is more than predetermined threshold.
In the first realization method, transmission conditions are for detecting whether locator occurs change in location.Assuming that pre- timing
Between section be 1 minute, processor can detect geographical location indicated by the position signal obtained before 1 minute and current time is obtained
Whether the geographical location indicated by position signal taken is identical.When two geographical locations are identical, determine that position does not occur for locator
Variation is set, position signal is unsatisfactory for transmission conditions；When two geographical location differences, determine that change in location, position occur for locator
Confidence number meets transmission conditions.

It it is 1 minute, and the first distance between the position signal of locator obtained before 1 minute and the position signal of terminal is 30
Rice, the second distance between the position signal of locator and the position signal of terminal that current time obtains is 30 meters, and it is fixed to determine
For position device not far from terminal, position signal is unsatisfactory for transmission conditions；The position signal and terminal for the locator that current time obtains
Second distance between position signal is 40 meters, determines locator far from terminal, position signal meets transmission conditions.
Wherein, the position signal of terminal can establish bluetooth connection in locator and terminal, and in RF switch by the
What two-state was got before being switched to first state.
In the third realization method, transmission conditions are for detecting whether locator rocks.Assuming that predetermined threshold is
0, when the numerical value of the acceleration for the locator that current time obtains is zero, determine that locator is not shaken, position signal is discontented
Sufficient transmission conditions；When the numerical nonzero of the acceleration for the locator that current time obtains, determine that locator is shaken, position letter
Number meet transmission conditions.

Power consumption bluetooth module.
After processor control RF switch is switched to first state by the second state, the first access is in running order,
Position signal can be exported and give low-power consumption bluetooth component by signal component output at this time.
In step 605, when RF switch is in first state, position signal is exported by low-power consumption bluetooth component
To power amplifier.
In step 606, position signal is amplified by power amplifier, and amplified position signal is exported
To antenna.
Wherein, the technology that power amplifier is amplified signal is highly developed, does not repeat herein.

When the low-power consumption bluetooth component includes processor, the RF switch is controlled by the processor and is in described the
Two-state；
The bluetooth connection is established by the low-power consumption bluetooth component and the terminal；
The RF switch is controlled by the processor, and the first state is switched to by second state.
7. according to the method described in claim 6, it is characterized in that, it is described by the processor control the RF switch by
Second state is switched to the first state, including：
Every prescribed time period obtains the position signal of the signal component output output by the processor；
Detect whether the position signal meets transmission conditions by the processor；
When the position signal meets the transmission conditions, the RF switch is controlled by described second by the controller
State is switched to the first state.
8. the method according to the description of claim 7 is characterized in that described be by the processor detection position signal
It is no to meet transmission conditions, including：
When the signal component output is the positioning component, current position signal and previous position are detected by the processor
Whether confidence number is identical, when the current position signal and the prior location signal difference, determines that the position signal is full
The foot transmission conditions；
When the signal component output is the positioning component, current position signal and the end are calculated by the processor
Second distance between the first distance between the position signal at end and prior location signal and the position signal of the terminal, inspection
Survey it is described first distance whether be more than the second distance, when it is described first distance be more than the second distance when, determine described in
Position signal meets the transmission conditions, and the position signal of the terminal is that the processor is controlling the RF switch by institute
It states the second state and is switched to what the first state was got before；
When the signal component output is the acceleration transducer, the number of the position signal is detected by the processor
Whether value is more than predetermined threshold, when the numerical value of the position signal is more than the predetermined threshold, determines that the position signal is full
The foot transmission conditions.
9. according to any method of claim 6 to 8, which is characterized in that the method further includes：
After the amplified position signal is sent to the terminal by the antenna, by being penetrated described in processor control
Frequency switch is switched to second state by the first state.
