Specific embodiments of the invention are as follows:
With reference to figure 5-6,258 processors of use carry the analog to digital converter of a 12bit, and sample frequency is 125KHz.Utilize an A/D input pin pinU11(INAUX0 of processor), be extended to 8 road AD(A0 ~ A7 by analog switch), wherein A4, A5 are used for plane type recognition, and A6 is used for version identification.
As shown in Figure 7: concrete regulation is: the analog to digital converter of processor uses 3.3V as the reference voltage, 3 external road circuit are by divider resistance dividing potential drop, by 0.4125V mono-grade, No. one bleeder circuit has 3.3V/0.4125V=8 shelves, analog to digital converter sampled value is maximum is 212=4096, so every grade 512.Represent by triad, first 2 of xxx, A4+A5 form type number, xxxxx, 25=32 kind type altogether, and last position of A5+A6 forms version number, xxxx, altogether 24=16 kind version.Here we use M to represent type number, and V represents version number.Wherein, because analog to digital converter pin is extended to 8 tunnels by an analog switch, analog switch can affect the sampling precision of AD, and the reference voltage of analog to digital converter is not very stable, and sampling error is larger, so regulation uses 0.4125V mono-grade.
By regulation, 8 grades are divided 3.3V voltage, convert the binary code of 3 to, get Δ=0.4125V, and specify that the voltage of all numerical value between 0.0000V-0.4125V is all used as 0 × Δ and is treated, represent with Binary Zero 00, voltage between all numerical value 0.4125V-0.8250V is all used as 1 × Δ and is treated, represent with Binary Zero 01 ... etc., as shown in table 1.In order to sampled value is not by the impact of voltage fluctuation, when configuration resistance is arranged, voltage is arranged the intermediate value of voltage range, voltage is had ± 0.20625V domain of walker.And 0 grade and 7 when being minimum sampled value and maximum sampled value, directly receive 0 level respectively and analog to digital converter reference voltage 3.3V level can accurately be sampled.Shown in the divider resistance table 1 that each shelves voltage is set using.
Table 1
The analog to digital converter used is 12 analog to digital converters, the sampled value of 12bit is converted to the sampled value of 3bit.Collection value is dextroposition 9 after smothing filtering.The binary number that A4, A5, A6 are corresponding three three.Get three of A4 number high 3 as type, high two low two as type number of A5, draw the type number of a 0x00 ~ 0x1F by bit arithmetic.A low high position as version number of A5, three of A6, as low three, draw the version number of a 0x00 ~ 0x0F by bit arithmetic.Table look-up with version number according to type number and draw corresponding type version.
Such as, the machine of K320-V2.2, type M=01, version number V=02.So the binary number of M should be the binary number of 00001, V is 0010.According to our afore mentioned rules, obtain A4=000, A5=010, A6=010.Known according to table 1:
A4 belongs to 0 grade, and magnitude of voltage should be set to 0, and pull-up resistor does not weld, and pull down resistor gets 0 Ω.
A5 belongs to 2 grades, and magnitude of voltage should be set to 1.03125V, and pull-up resistor gets 33K, and pull down resistor gets 15K.
A6 belongs to 2 grades, and magnitude of voltage should be set to 0V, and pull-up resistor gets 98K, and pull down resistor gets 30K.
12 analog to digital converter sampling precisions are 3.3V/4096=0.0008056640625V, and the sampled value on A4 is 768, and scale-of-two is 1100000000, and moving to right 9 is 001, i.e. [768/512] ≈ 1 grade.
M is high two compositions having A4 and A5, and V is that low of A5 is three of high-order and A6 and does low level and form.So there is the scale-of-two of A4 to be M binary shift right two (being equivalent to divided by 4); The scale-of-two of A5 be the binary shift left one (being equivalent to be multiplied by 2) of M add the most significant digit of V move to right 3 (being equivalent to divided by 8) and to 8 complementations; The scale-of-two of A6 is the binary low three of V, is equivalent to V to 8 complementations.Use formulae discovery gear number, gear number uses formulae discovery:
D(A4)=M/4; //A4 equals type and moves to right two
D(A5)=(M*2+V/8) %8; //A5 equal type move to left one add version move to right 3 and to 8 complementations
D（A6）= V%8。//A6 equals version to 8 complementations
Magnitude of voltage uses formulae discovery (M is type number, and V is version number)
VA4=[M/4]*0.4125+0.20625；
VA5=(M*2+V/8)%8*0.4125+0.20625；
VA6=V%8*0.4125+0.20625。
Domain of walker ± 0.20625 of voltage.
Physical circuit realization such as Fig. 5 ~ Fig. 6 EXP-AD is the AD sampling pin of processor.Processor is by control AD-C1, and AD-C2, AD-C3 select which is switched to and carry out AD sampling.
When the identification of type version, the mode of sampling as following table 2 is carried out.
Table 2
In specific embodiments of the invention, Machine-AD1 and Machine-AD2 of MUX is used for representing the identification of product type, and in this Fig. 6, Machine-AD1 crosses resistance R155 and directly pulls down to ground, and R153 does not weld, and makes Machine-AD1 be 0V; Machine-AD1 crosses resistance R158 pull-up, and R161 is drop-down, makes Machine-AD2 dividing potential drop be 1.03V; Tabling look-up 1, to obtain type version be 2.Obtaining version according to above-mentioned formulae discovery is V2.2.
Version-AD2 crosses resistance R157 pull-up, and R160 is drop-down, makes Version-AD2 dividing potential drop be 1.01V; According to above-mentioned formulae discovery, then table look-up 2 type be 0x01, corresponding K320 type.
Get this type and main board version configuration information corresponding to hardware according to planning table built-in in advance again, be identified as K320 type V2.2 version, continue the program that load operating is corresponding.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replacement are all included in the application's claim limited range.
