Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its His embodiment, shall fall within the protection scope of the present invention.

It is to be appreciated that the description of " first ", " second " involved in the present invention etc. is used for description purposes only, and should not be understood as Its relative importance of indication or suggestion or the quantity for implicitly indicating indicated technical characteristic.Define as a result, " first ", The feature of " second " can explicitly or implicitly include at least one of the features.In addition, the technical side between each embodiment Case can be combined with each other, but must be based on can be realized by those of ordinary skill in the art, when the combination of technical solution Conflicting or cannot achieve when occur will be understood that the combination of this technical solution is not present, also not the present invention claims guarantor Within the scope of shield.

First embodiment, as shown in Figure 1, a kind of optical sampling module 2 for having both sampling width and precision, including photocell 201, the signal picker 202 being connect with photocell 201, processor 203 and sampling resistor 204；Sampling resistor 204 is resistance R1, one end of sampling resistor 204 are connected between signal picker 202 and photocell 201, and the other end is in series with N number of compensation electricity Resistance 205, each 205 both ends of compensation resistance are parallel with switch, and the control terminal of switch is connect with processor 203；Compensating resistance 205 can To be arranged as needed, can be set to 1,2 or multiple, in the utility model, compensation resistance 205 using 2 come Illustrate, be resistance R2 and resistance R3 respectively, the both ends resistance R2 are parallel with switch one, and the both ends resistance R3 are parallel with switch two, switch One and the control terminal of switch two be electrically connected respectively with processor 203, processor 203 individually control switch one and switch two It opens and breaks, when processor 203 exports low level, switch is disconnected, i.e., switch one or/and switch two disconnect, and compensation resistance 205 connects Enter into sampling resistor 204 to increase the resistance value of resistance when signal picker 202 samples, i.e. resistance R2 or/and resistance R3 access In sampling resistor 204；When processor 203 exports high level, switch connection, i.e. switch one or/and switch two are connected, compensation electricity The resistance value of resistance, i.e. resistance R2 or/and resistance R3 are bypassed when 205 short circuit of resistance is to reduce the sampling of signal picker 202, resistance R2 Or/and resistance R3 is not involved in resistance when signal picker 202 samples.

As depicted in figs. 1 and 2, the resistance value of sampling resistor 204 is greater than the resistance value of compensation resistance 205, small one and large one two are not With resistance sampled, and by processor 203 come control switch close or close switch compensate resistance 205 access or Person does not access, and both can guarantee that high RST does not overflow, while also can normally recognize low signal.Specific principle is that signal is adopted Storage 202 detect signal it is strong when, processor 203 switches so that the resistance of the sampling of signal picker 202 is small, guarantees signal It does not overflow；When the signal that signal picker 202 acquires is very faint, processor 203 switches so that signal picker 202 The resistance of sampling is big, guarantees that faint signal also normally can be identified and be sampled.Sampling system is answered according to actual Then the sampling resistor value initialized with scene setting one carries out first time sampling, the number that processor 203 is sampled according to this According to being analyzed, if data are overflowed, the resistance when sampling of 202 front end of representation signal collector is excessive, then reduces letter Resistance when number collector 202 samples, is then once sampled again and exports suitable data；If it find that sampling for the first time Weak output signal, then the sampling resistor of 202 front end of representation signal collector is too small, then increase sampling when resistance simultaneously it is defeated Suitable data out.By the optimization of processor 203, the resistance value of resistance when sampling can be adjusted in real time, obtains optimal adopt Sample data.

As depicted in figs. 1 and 2, the step of optical sampling module 2 samples are as follows: S1, optical sampling module 2 are answered according to actual The sampling resistor value initialized with scene setting one；Then S2 carries out first time sampling；S3, signal picker 202 will acquire Signal pass to processor 203, processor 203 is analyzed according to this data sampled and judges the power of signal；S4, If data-signal is weak, i.e. the weak output signal of sampling for the first time, then resistance mistake when 202 front-end sampling of representation signal collector Small, 203 control switch of processor disconnects the resistance value of resistance when increasing sampling, is then sampled again, until output is suitable Data；S5, if data-signal is strong, i.e., data are overflowed, then resistance when 202 front-end sampling of representation signal collector is excessive, At this point, 203 control switch of processor is closed the resistance value of resistance when reducing sampling, then sampled again；S6, until output is closed Suitable sampled data；, therefore dynamic data sampling may be implemented.

Preferably, as shown in Figure 1, switch is triode, the input terminal and output end of triode are connected to compensation resistance 205 The control terminal at both ends, triode is connect with processor 203.In the utility model, compensation resistance 205 is illustrated using 2, respectively It is resistance R2 and resistance R3, the both ends resistance R2 are parallel with switch one, and switch one is triode Q1, and the both ends resistance R3 are parallel with switch Two, switch two is that the control terminal of triode Q2, triode Q1 and triode Q2 are electrically connected with processor 203 respectively, processor 203 Opening and breaking for triode Q1 and triode Q2 is individually controlled, is connected with resistance R7 between triode Q1 and processor 203, three It is grounded between pole pipe Q1 and resistance R7 by resistance R6；Resistance R5, triode Q2 are connected between triode Q2 and processor 203 It is grounded between resistance R5 by resistance R4.Wherein, the cathode of photocell 201 is connect with signal picker 202, photocell 201 Anode connect to power supply.

As depicted in figs. 1 and 2, optical sampling module 2 has unique design, compares existing product, has higher Sensitivity and broader signal measurement range.Optical sampling module 2 is using optical texture focusing altogether, total focusing optics The optical path focusing capability of structure is strong, and excitation light source is after over-focusing, and energy is concentrated, therefore can inspire bigger signal, together When altogether focusing optical texture can acquire more optical signals, after over-focusing, be transmitted to light on photoelectric sensor more Add concentration, signal strength is bigger, and stability is more preferable, and anti-interference ability is stronger.The optical element of optical sampling module 2 includes: purple Outer LED light, plano-convex lens, narrow band filter, collimation lens and dichroscope.Processor 203 in optical sampling module 2 is adopted With the control program of dynamic gain, for small-signal, optical sampling module 2 can be improved faint using the gain of high magnification numbe The amplitude of optical signal reduces the influence degree of interference signal, and for strong optical signal, processor 203 uses the gain of low power number, Anti- stop signal overflows and result is caused to be distorted.By the scheme for taking focusing performance excellent on optical texture, increase in conjunction with dynamic The control program of benefit, optical sampling module 2 can either have high detection sensitivity simultaneously and can have extremely wide detection Range has excellent performance compared to current existing product.
