The initial time that hardware layer can filter out current demand signal is current less than preset value with the time interval of the initial time of previous signal
Signal, the MCU of receiving terminal do not make any response to such signal, and the only initial time and previous letter to current demand signal
Number the time interval of initial time respond more than or equal to the current demand signal (i.e. the Z signal) of preset value, so can be with
The detection efficiency of follow-up useful signal is improved, so as to reduce the workload of MCU.
Further, the filtration of above-mentioned hardware layer can be in the following ways：The signal receiver of receiving terminal is from first for receiving
The initial time T of individual useful signal starts timing, in the time range of T+ preset values does not receive any signal, and pre- from T+
If restarting again to receive signal from being worth this moment, until receiving the Z signal (Z=2), and with the Z signal (Z=2)
Initial time as new T, repeat the above steps, till the Y signal is received.
Further, the preset value be obtain the corresponding relation in time interval minima.Due to current demand signal
Minima of the time interval of initial time and the initial time of previous signal less than the time interval in the corresponding relation, then
The current demand signal is necessarily not belonging to the useful signal described in step 103, therefore can not receive the current demand signal.
In an optional embodiment of the present embodiment, in the case where transmitting terminal sends handshake to receiving terminal, then in step
Receive described in rapid 102 for, before indicating signal that data transfer starts, K signal can also be received, detect K signal
Between whether meet preset relation, wherein, the value of K can be default.Receiving terminal can pass through to judge
It is no to meet preset relation and judge whether the K signal is handshake.The step for receiving Z signal is performed if preset relation is met
Suddenly, that is, determine that the K signal for receiving is handshake, the signal after K signal is data signal；If being unsatisfactory for presetting
Relation then continues to detect K follow-up signal, until detecting K signal for meeting preset relation, that is, is being not detected by holding
In the case of handss signal, receiving terminal persistently detects handshake, just starts receiving data until detecting handshake, that is, shakes hands
Last signal of signal is indicated for the signal that data transfer starts, such that it is able to avoiding the maloperation of transmitting terminal or making an uproar
Acoustical signal disturb in the case of to receiving terminal sending signal situation, while improve data transmission efficiency.
Further, whether the K signal meets preset relation can be：Time interval (K between K signal of detection
>=2 and K is integer, and at least two) initial time one time interval of generation of two signals, handshake should judge
The very first time is spaced whether meet preset relation and the second time interval between, wherein, the very first time is at intervals of i-th signal
Time interval between start time and the start time of the i-th -1 signal, the second time interval are the start time of i-th signal
And the time interval between the start time of i+1 signal, i=2,4 ... ..., 2j, j=(K-1)/2, K >=3 and K are odd number.
In this optional embodiment, the preset relation met between very first time interval and the second time interval can arbitrarily be sent out
The relation that sending end is made an appointment with receiving terminal, such as the second time interval are two times of very first time interval, naturally it is also possible to for other
Relation, concrete the present embodiment are not construed as limiting.Transmitting terminal meets the handshake of preset relation by sending so that receiving terminal can lead to
Cross whether the signal for receiving meets preset relation to judge to receive whether signal is handshake.For example, when producing and send
During 5 handshake, including 4 time intervals t0, t1, t2 and t3, wherein, very first time interval can include t0 and t2,
Second time interval can include t1 and t3, and the preset relation that wherein very first time interval is met with the second time interval can be：
T1=2t0, t3=2t2.
Further, the K signal that can also pass through to receive carries time parameter, then in a step 101, can be according to K
Signal determines time parameter, then according to the time parameter come the corresponding relation in obtaining step 101.It is alternatively possible to first really
Determine very first time interval group and the second time interval group, wherein, very first time interval group includes that at least one very first time was spaced,
Second time interval group includes at least one second time intervals, then according to very first time interval group and/or the second time interval group
Determine time parameter.For example, if 5 handshake of transmitting terminal transmission, time parameter includes two：Etu and pdt, then
Very first time interval group includes：T0 and t1, then can be t0=etu, t1=etu+pdt, then receiving terminal can be true according to t0 and t1
The value of parameter etu of fixing time and pdt；Or, it is also possible to determined according to the t2 in the second time interval group and t3,2t2=2etu,
2t1=2 (etu+pdt), receiving terminal can also determine the value of time parameter etu and pdt according to t2 and t3.Or, t0 and t1
Other relations can also be met, as long as the value of time parameter etu and pdt can be obtained by the value of t0 and t1.Separately
Outward, if time parameter only one of which, directly can also determine by a time interval in K signal that the time joins
Number, or, if time parameter has three, can be by the relation of the multiple time intervals satisfactions between K signal come really
The value of fixed these three time parameters, concrete the present embodiment are repeated no more.Time parameter is determined by K signal, can be overcome and be connect
The theoretical time parameter of the receiving end situation inconsistent with parameter actual time, ensures the correctness of data transfer.
Similar to the signal of transmission data, receiving terminal can confirm to receive K in the case where K low level pulse is detected
Individual signal.Or, or detect K high level pulse, the low level/high level pulse can adopt square wave, sine
The modes such as ripple are realized.It is preferred that providing high level to receiving terminal using low level pulse, i.e. transmitting terminal is detected, needing to send K
During individual signal, K low level pulse is produced, so, when transmitting terminal is communicated with receiving terminal, receiving terminal can be carried using transmitting terminal
For high level as power supply, or inside receiving terminal, be not provided with power supply, and directly use the high level of transmitting terminal as power supply,
Using the equipment of the method, when information exchange is carried out, same single line can be used while completing power supply and information reception, reduced
Equipment volume and manufacturing cost.
In an optional embodiment of the present embodiment, X signal also including A end signal (A >=1 and for integer),
Or be further continued for receiving A end signal after the Y signal is received；End signal can be identical with handshake, also may be used
To be the signal of other specific formats, by the end signal, receiving terminal can determine whether whether data bit string receives to be terminated.
Below with Bit String to be received as 0011100100, N=1, the data receiver method that the present embodiment is provided is carried out simply
Illustrate：
Step 101, obtains the corresponding relation of each Bit String and time interval in the Bit String that 2 length are 1, wherein, 2
The Bit String is different, and the corresponding time interval of the different Bit Strings is different.
It is alternatively possible to first determine the time parameter of current transmission, for example, it is assumed that the time parameter of current transmission is two times
Parameter, i.e. very first time parameter etu and the second time parameter pdt, wherein etu=10 μ s, pdt=30 μ s.The number of time parameter
There is no corresponding relation with N, the present embodiment is not restricted to the concrete number of time parameter, as long as each data can be given expression to
The corresponding time interval of bit.In N=1, Bit String (the i.e. number of 1 bit that length is 1 is obtained according to time parameter
According to or 1 Bit String) corresponding to time interval, i.e., 0 corresponding time interval be etu, 1 corresponding time interval be pdt,
In the present embodiment, between the time that can adopt the multiple combination form of time parameter to express length corresponding to 1 Bit String
Every, it is not limited to this.
Step 102, receives Y signal, wherein, first signal in the Y signal is for indicating data transfer
The signal of beginning, wherein, Y is the total quantity of the signal for receiving.
Step 103, by described for indicating that the signal that data transfer starts is defined as first useful signal C1。
In this example, it is assumed that for indicating that the signal that data transfer starts is first signal after predetermined instant, the letter
Number for data transfer first signal.
Step 104, judgement receive the initial time of Z signal and the time interval of the initial time of previous useful signal
It is whether a time interval in the corresponding relation for obtaining, is then if so, useful signal by the Z signal record,
Wherein, Z=2,3,4 ... ..., Y；
For example, as shown in Fig. 2 calculating the initial time and first useful signal that the 2nd signal for receiving obtains the signal
C1The time interval of initial time be time in 5 μ s, the time interval and step 101 corresponding to 1 Bit String 0 and 1
Interval differs, therefore the signal is not useful signal, is invalid signals D by the signal record, should give up the invalid signals
D。
Continue to calculate the initial time and first useful signal C of the 3rd signal1Initial time time interval be 10 μ s, should
Time interval is identical with the time interval corresponding to 1 Bit String 0 in step 101, therefore the signal is useful signal, should
Signal record is second useful signal C2, and record second useful signal C2Initial time.
Calculate the initial time and second useful signal C of the 4th signal2Initial time time interval ...
By that analogy, till the Y signal ended for judging to receive.
Step 105, receives 11 useful signal (C1To C11), determine rising per two neighboring signal in this 11 signals
Begin the moment between time interval, obtain 10 time intervals be followed successively by etu, etu, pdt, pdt, pdt, etu, etu, pdt,
etu、etu。
Step 106, in obtaining above-mentioned 10 time intervals, each time interval distinguishes corresponding 1 Bit String, respectively obtains etu
1 Bit String 0 of time interval transmission, obtains 1 Bit String 0 of etu time intervals transmission, obtains pdt time intervals biography
1 defeated Bit String 1,1 Bit String 1 ... for obtaining the transmission of pdt time intervals obtain 1 of etu data breaks transmission
Bit String 0.
Step 107, the Bit String of each time interval transmission is spliced, and obtains the bit sequence of 10 time interval transmission
