2. department of general surgery's wound-cleaning device as claimed in claim 1, it is characterised in that the controller is for interference signal and reference
The multimode situation of each self-contained some interference characteristic vectors of signal, disturbance state now
S(VI, VS),
It is calculated as below：
Wherein S [VI, VS]M×N
It is referred to as each element in disturbance state matrix, matrix
Represent VI
In k-th of characteristic vector
And VS
In l-th of characteristic vector disturbance state, when each element is not disturbed in only two characteristic vector set,
S(VI, VS)=0
Interference signal is not just disturbed contrast signal formation；Conversely,
S(VI, VS) ＞ 0,
Now interference signal will form interference to contrast signal.
3. department of general surgery's wound-cleaning device as claimed in claim 1, it is characterised in that the wireless location method of the controller is specific
Comprise the following steps：
Anchor node coordinate in node O communication ranges to be positioned is Aixi,yi, wherein i=0,1 ..., n n >=4；
Step one：Node docking collection of letters r t to be positioned sample obtaining sampled signal rn, wherein, n=0,1 ..., N-1, N
The subcarrier number that OFDM symbol is included is represented, while the sending node of the received signal of record is Ai(xi,yi)；
Step 2：According to sampled signal r n, cross correlation value E is calculated：
Step 3：According to log-distance path loss model model, equation below calculates node to be positioned and anchor node AiBetween away from
From：
Pr d′i=Pr d0-10·γlg d′i+Xσ；
Wherein, Pr d 'iRepresent that apart from transmitting terminal distance be d 'iWhen the cross correlation value that obtains, Pr d0Represent apart from transmitting terminal d01 meter
Locate the cross correlation value obtained, γ represents path-loss factor, and lg represents the logarithm operation that bottom is 10, XσIt is 0, mark to obey average
The Gaussian Profile that quasi- difference is；
It is respectively d ' to calculate the distance between each anchor node and node O to be positioned using above formulai, the seat of corresponding anchor node
Mark is respectively Ai xi,yi, wherein i=0,1,2 ..., n；
Step 4：According to adaptive distance correction algorithm, the coordinate Ox, y of node to be positioned are estimated.
