Fig. 3 is painted the state transition diagram of an embodiment according to the present invention, with reference to the method flow diagram and Fig. 2 of Fig. 1
Schematic device be illustrated.In subtracting energy state S01, attempt to reduce transimission power used in wireless transceiver 2, with test
Lower transimission power, which whether can be used, successfully to be communicated.In an embodiment, wireless transceiver 2 has multiple pre-
If usable transimission power grade (such as 10dBm, 9dBm, 8dBm ... etc.), enter that subtract can state S01 drop in each
When low transmission power, it can choose and turn down one or more levels transimission power grade.
Transimission power is progressively reduced in subtracting energy state S01, until judgement transmission failure, such as ACK can not be properly received
Respond, representing current transimission power may be too low so that wireless transceiver 2 can not successful data transmission package to far end device
30, then enter recoil state S02.It in one embodiment, can be with when far end device 30 can not have successfully received data packet
It transmits NAK to respond, therefore communication unit 204 can be responded when receiving NAK response, or being not successfully receiving ACK
When, processing unit 202 determines to enter recoil state S02.
In recoil state S02, progressively increase transimission power, until judging transmission success, such as ACK can be properly received
Respond, enter back into compensating coefficient S03, can so learn wireless transceiver 2 in current environment, about needed for use it is minimum
Transimission power, it is ensured that data can save power consumption with Successful transmissions and effectively.The process for increasing transimission power for example can be with
It is that one or more levels transmission function is turned up from multiple preset usable transimission power grades when entering recoil state S02 every time
Rate grade.
And progressively increase transimission power during, wherein may some data packet lose, Wu Facheng
Function is received by far end device 30.Since using energy transmission, these last fail are sent to far end device 30 to wireless transceiver 2
Package, therefore cause additional power loss, processing unit 202 can be used to calculate increase transimission power herein during,
Because adding up capability of energy dissipation Ec consumed by transmission failure.
Accumulative capability of energy dissipation Ec can be and consume the positively related numerical value of energy, such as can be made by accumulative transmission every time
Energy, power, voltage, electric current or other be relevant to consumption energy numerical value and be calculated.For example, if in returning
During multiple state S02 increases transimission power, communication unit 204 is sequentially sealed using transimission power Px, Py, Pz transmission data
Packet, these three data packets, which all fail, to be sent to far end device 30 (communication unit 204 receives NAK response, or does not receive
ACK is responded), then this data transmission three times all causes power loss, and processing unit 202 calculates accumulative capability of energy dissipation Ec, example
Such as it is equal to Px+Py+Pz.Certainly, it is merely illustrative a kind of possible embodiment for calculating accumulative capability of energy dissipation Ec, meter herein
The implementation for calculating accumulative capability of energy dissipation Ec is not limited to this, and for example, processing unit 202 can also use power over time
Integral calculation, or by the cumulative numerical value for being positively correlated with consumption power to calculate accumulative capability of energy dissipation Ec, such as can tire out
Add consumption electric current when each transmission.
In recoil state S02, it is assumed that when transimission power increases to Pc, can be successfully received ACK response, then then into
Enter compensating coefficient S03, and continues to transimission power equal to Pc.In compensating coefficient S03, for previously in recoil state
The accumulative capability of energy dissipation Ec of S02 consumption is compensated.Processing unit 202 can be used to calculate accumulative energy-saving index Es, calculating side
Method for example can be according to current transimission power Pc compared with an a reference value, and accumulative energy-saving index Es can be and save energy positive
The numerical value of pass, for example, can by accumulative transmission every time compared to energy that a reference value is saved, power, voltage, electric current or other
It is relevant to the numerical value for saving energy and is calculated.This, which calculates a reference value used in step, can be a mark predetermined
Quasi- reference value, in another example can be the maximum transmission power that wireless transceiver 2 can use.Such processing unit 202 can obtain
Know in the every transmission primaries data packet of compensating coefficient S03, the power consumption that can be saved compared to this reference value.Persistently maintain this
Transimission power Pc is more than accumulative capability of energy dissipation Ec until accumulative energy-saving index Es, that is, represents and previously wasted in recoil state S02
The energy fallen has been compensated for finishing in current compensating coefficient S03, and then processing unit 202 determines to enter maintenance state S04.
In one embodiment, processing unit 202 can be used electric current and calculate accumulative capability of energy dissipation Ec, can also use electric current
Accumulative energy-saving index Es is calculated, is finished with knowing when to compensate.For example, if being calculated by cumulative electric current
Accumulative capability of energy dissipation Ec numerical value be ilost, and assume that a reference value in this can be used using wireless transceiver 2
Maximum current imax, transmitting electric current used in data packet every time in compensating coefficient S03 is icomp, then processing unit can be counted
Data packet transmission times needed for calculating compensating coefficient S03Denominator (the i of aforementioned calculating formulamax-
icomp) it is positively correlated with saving power, after compensating coefficient S03 data packet transmission times reach Cnt, maintenance state can be entered
S04。
According to the Poewr control method and wireless transceiver of above-described embodiment, transmission function can be gradually decreased subtracting energy state
Rate, and transimission power is gradually increased in recoil state, to find transimission power used in suitable wireless transceiver, Neng Gouyou
Effect saves power consumption and extends battery life.In addition, the energy spent by recoil state, can be mended in compensated stage
It repays, compensates for the power loss that can not previously transmit data.
Fig. 4 is painted the state transition diagram of another embodiment according to the present invention.In this embodiment, original state is further included
S00, original state S00 are, for example, the state initially entered when the booting of wireless transceiver 2 or restarting.In original state S00,
Processing unit 202 can set the initial value of transimission power, and can set accumulative capability of energy dissipation Ec as zero, enter that subtract can state later
S01.The initial value that transimission power is set in original state S00 can be used as used a reference value when compensating coefficient S03,
It calculates accordingly and saves power.
In subtracting energy state S01, transimission power is progressively reduced since initial value, after judging transmission success (such as at
Function receives ACK and responds), maintenance subtract can state S01, so persistently reduce transimission power until judgement transmission failure (such as can not
ACK is properly received to respond), into recoil state S02.For example, wireless transceiver 2 can be passed every a fixed time period
Send a data packet, and detected whether to receive ACK response, processing unit 202 can according to whether receive ACK respond determine it is next
A state.
Increase transimission power in recoil state S02, after judgement transmission failure (such as ACK can not be properly received and responded),
Recoil state S02 is maintained, continues to increase transimission power after judging transmission success (such as be properly received ACK and respond), enters
Compensating coefficient S03.In an embodiment, the cumulative data packet of transmission every time can be used in recoil state S02 processing unit 202
Transimission power is to obtain accumulative capability of energy dissipation Ec.
Assuming that entering compensating coefficient S03 when transimission power is Pc.In compensating coefficient S03, when communication unit 204 successfully connects
When receiving ACK response, representing current transimission power Pc can be with successful data transmission package, therefore can compensate for previous loss energy
Amount, processing unit 202 can determine to maintain compensating coefficient S03.And when judgement transmission failure (such as communication unit 204 can not be at
Function receive ACK respond when), indicate in current communication environment, transimission power Pc can not successful data transmission package, therefore need
It is further added by transimission power, processing unit 202 can determine to enter recoil state S02.It also, may be also that is, in compensating coefficient S03
It does not compensate and finishes accumulative capability of energy dissipation Ec, that is, transmission failure occurs or the situation of ACK response can not be properly received, jump back at this time
Recoil state S02 to increase transimission power, and continues accumulation calculating in recoil state S02 and adds up capability of energy dissipation Ec.
In one embodiment, processing unit 202 is to according to " initial value of transimission power set by original state S00 "
Saving power is calculated with the difference of " the transimission power Pc that compensating coefficient S03 is used ".Initial value can there are many may setting
Mode can give initial value appropriate according to circuit design.For example, in the initial of original state S00 setting transimission power
Value can be maximum transmission power Pmax used in wireless transceiver 2, then the saving power of compensating coefficient S03 can be equal to
It (Pmax-Pc), is to calculate to transmit data packet using transimission power Pc in compensating coefficient S03 every time, compared to using maximum
Transimission power Pmax transmission, can save how many power consumption.
In one embodiment, adding up the embodiment of capability of energy dissipation Ec in the compensation of compensating coefficient S03 is processing unit
202 to subtract saving power for accumulative capability of energy dissipation Ec, and the lower limit value of accumulative capability of energy dissipation Ec is zero, when accumulative energy consumption refers to
When mark Ec is reduced to zero, i.e. compensation finishes accumulative capability of energy dissipation Ec.Saving power therein can be according to the transmission of compensating coefficient S03
Power P c is calculated compared with a reference value.Also that is, accumulative capability of energy dissipation Ec can be subtracted section when entering compensating coefficient S03 every time
Save power；And when entering recoil state S02 every time, accumulative capability of energy dissipation Ec can be added the transmission used in recoil state S02
Power.When accumulative capability of energy dissipation Ec is reduced to zero, representative has been compensated for finishing, and can enter maintenance state S04.
Above-mentioned is a kind of exemplary implementation, and another example implementation mode can be when recoil state S02, according to
Transimission power increases accumulative capability of energy dissipation Ec, when compensating coefficient S03, increases accumulative energy-saving index Es according to transimission power, in
Accumulative energy-saving index Es is more than to enter maintenance state S04 after adding up capability of energy dissipation Ec, and can will tire out after entering maintenance state S04
Meter energy-saving index Es is set as zero, and accumulative capability of energy dissipation Ec is set as zero.
In maintaining state S04 that can maintain transimission power Pc the first predetermined time length, processing unit 202 can be used to calculate in
The transmission quality of first predetermined time length, to determine maintenance state S04 after will enter subtract can state S01 or reply shape
State S02.If transmission quality is worse than the first critical value Th1, it is too low to represent transimission power used in maintenance state S04, and makes
Transmission quality is poor, and processing unit 202 can determine to enter recoil state S02, to increase transimission power.Conversely, if transmission quality
Better than the first critical value Th1, represent transimission power used at present there are also the space declined again, then processing unit 202 determine into
Enter to subtract energy state S01, to reduce transimission power.In one embodiment, transmission quality can be according to packet error (Packet
Error Rate, PER) determine, calculate maintain state S04 the first predetermined time length in, success transmit package with lose
The package number of mistake, packet error is higher, and the transmission quality that represents is poorer, therefore when packet error is greater than the first critical value Th1
When (for example, 1%), recoil state S02 can be entered, when packet error is less than the first critical value Th1, can enter and subtract energy shape
State S01.
Fig. 5 is painted the schematic diagram of the transimission power of an embodiment and time relationship according to the present invention, it can be seen that wirelessly
The state of transceiver switches and the corresponding variation situation of transimission power.Transimission power is set as initial value P when original state S00I,
Then in subtract can state S01 (time t0~t1), transimission power is gradually decreased until can not have successfully received ACK response, in this
In example, when transimission power drops to P1When receive NAK response, into recoil state S02.In recoil state S02 (time t1~t2) by
Until cumulative plus transmission rate function is responded until having successfully received ACK, in this example, when transimission power increases to P3When enter compensation shape
State S03.In recoil state S02 and calculate accumulative consumption ENERGY E, the number that e.g. can not be successfully sent to and (indicate in figure with NAK)
According to (such as the E=P of transimission power summation used in package1+P2)。
Then in compensating coefficient S03 (time t2~t3) maintain transimission power P3, and saving power is calculated, save power example
Such as it is equal to the difference (P of initial value and current transimission powerI-P3), one data packet of every transmission can be by accumulative consumption ENERGY E
It subtracts and saves power (PI-P3), when accumulative consumption ENERGY E drops to zero, i.e. representative compensation finishes, into maintenance state S04.Such as
Example shown in fig. 5 is all to have successfully received the case where ACK is responded in compensating coefficient S03, if receiving in compensating coefficient S03
NAK is responded, then can enter recoil state S02, is further continued for increasing accumulative consumption ENERGY E.After compensation finishes accumulative consumption ENERGY E,
Maintaining state S04 (time t3~t4) maintain transimission power P3(the first predetermined time length is t to first predetermined time length4-
t3), further according in the transmission quality for maintaining state S04 detection, determine next state.Example as shown in Figure 5 is maintaining shape
The transmission quality of state S04 is better than the first critical value, therefore may then enter into and subtract energy state S01, is further continued for reducing transimission power, with
Trial further decreases power consumption.
According to the Poewr control method and wireless transceiver of above-described embodiment, can by judging transmission success or failure and
Transimission power is adjusted, to find the transimission power that suitable wireless transceiver uses, and can reach reduces power consumption extension production
The advantages of product service life.Furthermore, it is possible to compensate the power loss that generates due to package loses in compensating coefficient, and can be through
It calculates and when is compensated and finished.Can separately state-detection maintained to determine whether the transimission power used can reach at present
Good transmission quality enough, further increases or decreases transimission power, reaches in response to surrounding environment change and dynamically adjusts biography
The effect of defeated power.
Certainly, the invention may also have other embodiments, without deviating from the spirit and substance of the present invention, ripe
It knows those skilled in the art and makes various corresponding changes and modifications, but these corresponding changes and change in accordance with the present invention
Shape all should fall within the scope of protection of the appended claims of the present invention.
