Description
Technical field
The present invention relates to infrared detection field, more particularly to a kind of promoted based on dynamic benchmark correction algorithm infrared leaves inspection
The method for surveying accuracy.
Background technique
Cabinet for holding receipts receives equipment as a kind of common user's receipt self-service, and core function is that client is needed to lead by business hall
In drawer of the receipt taken by the corresponding deposit cabinet for holding receipts of user number, the family number and password that user can input oneself are got.
The granting of significant increase receipt and the efficiency received.It is widely used in business halls such as bank, electric power, postal services.
Because user cannot often take out receipt out of cabinet for holding receipts in time, so the drawer of cabinet for holding receipts will appear multiple receipt and wait for
The case where getting.User can occur receipt often when fetching list and leave.Therefore need cabinet for holding receipts that there is receipt to leave detection function
Can, remind user to have the receipt that leakage takes in time.
Receipt leaves detection generally using infrared emission detection method, installs a pair of of T-R tube by each drawer, passes through
The peak of signal strength determines whether receipt.To promote the space utilization rate of cabinet for holding receipts, and cost is reduced, row's drawer is multiple
With same group of infrared detection unit.But it is big and vulnerable to environment that this mode will lead to infrared signal difference that each drawer detects
It influences, and then the accuracy of detection is caused greatly to reduce, affect the usage experience of equipment.
Summary of the invention
The present invention is to overcome above-mentioned shortcoming, and it is an object of the present invention to provide a kind of red based on the promotion of dynamic benchmark correction algorithm
The method for leaving detection accuracy outside, the present invention is based on automatic correction algorithm, dynamic adjustment judges benchmark, and infrared inspection is substantially improved
The determination rate of accuracy of survey mode promotes user experience and substantially expands infrared detection distance, so as to use one group of infrared detection
The receipt state of one row or a column drawer, greatlys save cost and the device space.
The present invention is to reach above-mentioned purpose by the following technical programs: one kind is promoted infrared based on dynamic benchmark correction algorithm
The method for leaving detection accuracy, includes the following steps:
(1) circumstance of occlusion is detected using infrared transceiver device: infrared signal is emitted using infrared-emitting diode, it is infrared to connect
Closed tube receives infrared signal, receives blocking between transmitting tube by detection and judges whether drawer has receipt to leave；
(2) infrared signal that will test is converted into voltage signal by reception diode, is converted by AD/DA, turns
It is changed to digital signal；
(3) statistical analysis blocks the signal curve with unobstructed two states respectively, obtains the maximum difference of two kinds of curves
Characteristic is that curve rises and descending slope, curve rise and decline length；
(4) calculated curve slope and length characteristic, and benchmark is judged according to the correct sample dynamic corrections of history, specifically such as
Under:
(4.1) the corresponding signal strength F (A) of initial point A is calculated since drawer out code, and it is corresponding to calculate A+5 point
Signal length F (A+5) calculates signal strength difference △ F, i.e. △ F=F (A+5)-F (A) between A point and A+5 point；Difference △ F
It is compared, such as -10<△ F-M>10, then counts once, variable CONT adds 1 with a reference value M；Sampled point A is passed after the completion of calculating
Increase 1, successively calculates (A+1) and (A+1)+5；(A+2) with (A+2)+5......, until completing the closing of entire drawer, from
And the point of whole curve is calculated；
(4.2) work as CONT>80 item and determine drawer for sky, determine that there are receipt to leave if CONT<80；After result judgement,
Initialize CONT=0；
(4.3) dynamic correcting method of a reference value M is as follows: setting accumulated variables M1, when -10<△ F-M>10, then M1=M1
+△F；Statistical variable M2 is set, when -10<△ F-M>10, then M2=M2+1；Work as M2=10000, then a reference value is modified to M=
M1/M2。
Preferably, the infrared transceiver device can place up and down as needed or left and right is placed.
Preferably, the signal sampling rate is 250 times/second, the voltage value of 8 binary representation sampled points, highest
For 3.3V, corresponding sampled value is 255.
Preferably, the factor for influencing signal curve includes the use ring of the consistency of product batch production, product
The aging in border, product.
The beneficial effects of the present invention are: (1) the infrared accuracy rate for leaving detection judgement to receipt is improved, reaches more preferable
User experience；(2) it increases infrared to the distance of reaction blocked, makes receipt equipment that can be multiplexed a pair of infrared dress with entire row drawer
It sets, saves cost and space.
Detailed description of the invention
Fig. 1 is the schematic diagram of the invention left based on infrared transceiver device detection receipt；
Fig. 2 is the type signal curve for having receipt to leave in the embodiment of the present invention；
Fig. 3 is the type signal curve left in the embodiment of the present invention without receipt.
Specific embodiment
The present invention is described further combined with specific embodiments below, but protection scope of the present invention is not limited in
This:
Embodiment: a method of infrared leave is promoted based on dynamic benchmark correction algorithm and detects accuracy, including is as follows
Step:
(1) as shown in Figure 1, the circumstance of occlusion based on infrared transceiver device detection drawer circular hole, entire row drawer multiplexing one
To infrared transceiver device: emitting infrared signal using infrared-emitting diode, infrared receiving tube receives infrared signal, passes through detection
Receive blocking to judge whether drawer has receipt to leave between transmitting tube；Infrared transceiver device as needed can be placed up and down
Or left and right is placed；Wherein, when detecting the circumstance of occlusion in the hole 3CM, the distance between transmitting tube and access tube can be zoomed out
150cm, detection accuracy is greater than 99.99%, therefore whether the receipt that can be used for detecting an entire row drawer is left.
(2) infrared signal that will test is converted into voltage signal by reception diode, is converted by AD/DA, turns
It is changed to digital signal, sample rate is 250 times/second, and the voltage value of 8 binary representation sampled points, up to 3.3V are corresponding to adopt
Sample value is 255.
(3) as shown in Fig. 2, passing through the signal curve of analysis drawer hole occlusion state, that is, there is receipt state.It is dry that there are sharp waves
Signal and gentle fluctuations are disturbed, as shown in ABCD point.Drawer hole is remote from transmitting tube, can be whole by line since diffraction influences
Lifting.
(4) as shown in figure 3, passing through the signal curve of the analysis unobstructed state in drawer hole, i.e., without receipt state.Curve is with phase
To fixed slope and length rise and fall as shown in ABCD point.Drawer hole is remote from transmitting tube, due to the energy through drawer hole
Amount is reduced, and curve can entire lowering.
Wherein, the factor of signal curve is influenced also: product batch conformity of production, the use environment of product, product
Aging.
