Description

Sample collection device and method

Technical Field

The invention relates to the field of quality supervision and detection of constructional engineering, in particular to auxiliary equipment and a method for supervision and management of authenticity and uniqueness of a concrete test block sample, and more particularly relates to a concrete test block sample collection device implanted with an implant corresponding to an anti-counterfeiting ID and a method.

Background

In the field of construction, in order to monitor the quality of concrete entities, currently, in China, concrete test pieces are manufactured as detection pieces while concrete entities are poured, and construction units send the concrete test pieces to detection units for detection. The concrete test block reflects the strength of the concrete entity to a certain extent and is a main basis for quality evaluation of concrete, so that monitoring and management of the concrete test block have important significance for guaranteeing the quality of the concrete entity. In the actual operation process, the phenomenon that the witness sampling work is lack of attention of individual construction units or on-site supervision, the number of witness holding personnel is insufficient, the management work is not in place, even the witness is intentionally falsified in the raw material sampling or the concrete test block manufacturing, the test concrete test block sample is exchanged or some illegal contractors falsify the test sample for the test to be qualified occurs, and therefore the proper effects of the concrete test block sampling, maintenance and witness inspection work are lost. Therefore, it is indispensable how to perform anti-counterfeiting supervision on the concrete test block to ensure the reality of the concrete test block corresponding to the concrete entity, and at present, the traditional technical scheme adopted in the field is as follows:

firstly, an RFID chip is implanted into the interior or the surface of a concrete test block, and the unique authenticity of the test block is marked and confirmed through sample information stored by the RFID radio frequency chip.

The first technical scheme has the following problems:

1) the RFID chip is large in size, and when the RFID chip is implanted into a concrete test block, the strength structure of the concrete can be damaged, so that the concrete test block with the originally qualified strength can not pass a witness pressure strength test due to the addition of the RFID chip.

2) The RFID chip can be exchanged and the package can be removed before the concrete is not completely solidified, and the possibility that the RFID label in the concrete test block with low strength grade is stolen into the concrete test block with high strength grade to serve as the concrete test block with high strength grade exists.

3) The RFID chip has relatively high cost, and the use of a large number of RFID chips can increase the cost of a construction unit and cause great obstruction to comprehensive popularization and use.

And secondly, implanting a two-dimensional code label into a concrete test block manufactured on site, scanning the two-dimensional code on site by using a mobile phone, shooting the two-dimensional code label of the test block, implanting a picture and a mobile phone GPS positioning function, binding test block information, monitoring the whole process from manufacturing time, position and personnel to an experiment of the test block, and preventing a false test block from being manufactured.

The second technical scheme has the following problems:

1) the two-dimensional code label is implanted, when the concrete test block is manufactured and is not solidified, a long solidification time exists between the test block manufacturing and the complete solidification inspection, and the subsequent maintenance inspection can be performed generally by waiting for 8 hours or even longer. The supervisors cannot supervise the whole solidification process of the test block all the time, so that the possibility exists that the supervisors take out the two-dimensional code labels in the test block from the original test block when not in the presence, then make fake test blocks by using other concrete and implant the labels again.

2) The two-dimensional code label is bigger, generally pastes on the surface of concrete test block, drops easily, and the two-dimensional code label of pasting on concrete test block surface is fallen the package very easily, is pasted the two-dimensional code label that the concrete test block that intensity grade is low corresponds on the concrete test block that intensity grade is high by the people easily, realizes the concrete test block that the intensity grade is low with the concrete test block that intensity grade is high impersonation.

3) The concrete test block is made by cement, stone etc. and the two-dimensional code label is damaged easily, can't guarantee that information is by normal discernment.

The third scheme is an improvement of the second scheme and is added with photographing contrast, and the specific method comprises the following steps: when a concrete test block is manufactured, embedding an identification tag into the test block and exposing an identification part to the surface of the test block, immediately photographing the surface of the test block exposed with the identification tag after the test block is manufactured to obtain a non-solidified two-dimensional code photo, then transmitting the non-solidified test block photo and related photographing information during photographing to a detection unit, and after the test block is solidified and formed, transmitting the test block to the detection unit; and after receiving the test block, the detection unit shoots and compares the picture of the test block to be detected with the received picture in the non-solidified state under the same condition, if the picture is completely consistent, the test block is judged to be valid, and otherwise, the test block is judged to be invalid.

The third scheme has the following problems:

1) the detection unit is required to take a comparative picture under the same condition, which is difficult to achieve, the picture is taken when the concrete is in an unset state, and then the standard curing period of 28 days is required for the concrete, and during the period, the label on the concrete and the outer surface of the concrete can be correspondingly changed, so that the outer surface of the test block taken by the detection unit, the label and the outer surface of the test block taken by the detection unit in the unset state and the label are greatly different, and the operability is not strong.

2) The identification tags on the exposed surface of the concrete are also at risk of being replaced by a person.

In conclusion, the conventional anti-counterfeiting supervision scheme for the concrete test block cannot achieve efficient and all-around anti-counterfeiting supervision, and the risk that the concrete test block is illegally replaced exists to a great extent.

Based on the problems existing in the conventional technical scheme, researchers put forward that implants (such as magnetic bodies and the like) which do not damage the strength of the concrete test block are implanted into the concrete test block, and the implants are arranged according to a certain rule to be mapped into a certain anti-counterfeiting ID code in a database.

In a sample collection link, the traditional technical scheme mostly depends on manual comparison, the efficiency is low, and whether counterfeiting occurs or not can not be judged, and errors are easy to occur. Taking the two-dimension code label as an example, when a test block collects a sample, the sample collecting means is to manually scan a bar code or a two-dimension code attached to the surface of the test block through a code scanning gun, so as to obtain identity information corresponding to the test block, and store related information of the test block into a database. The code scanning gun only identifies the two-dimensional code attached to the surface of the test block, and then stores the identified relevant information of the test block into a database; it is not verified. Because the test block maintenance time is longer, the censorship side can change bar code or two-dimensional code on the test block surface at will when censorship the concrete test block, falls the package to the concrete test block easily, and sweeps a yard rifle and can both discern the two-dimensional code, can not carry out the true and false verification to the test block of pasting the two-dimensional code, leads to the data that the concrete test block detected unreal to can not reflect real engineering quality situation. In addition, bar codes or two-dimensional codes are also easy to damage or fall off, so that test block information can not be read when the code scanning gun detects, unnecessary workload is increased for detection of concrete test blocks, and authenticity of the test blocks during detection cannot be guaranteed.

Although the new scheme adopting the implant can effectively prevent illegal replacement and counterfeiting, the scheme also depends on manual comparison during sample collection, the efficiency is very low, time is consumed, and errors easily occur, so that the problems of authenticity verification, low efficiency and error easily in the sample collection link can be solved by the scheme for automatically collecting samples, which can be applied to a new anti-counterfeiting technology.

In order to better understand the present invention, in the embodiments of the present invention, the bearing object is exemplified by a concrete test block, and the implant is exemplified by a magnetic body.

According to one embodiment of the invention, the server is a cloud server, the communication module is a wireless communication module, the sample receiving device comprises a panel and a detection device, the panel is used for placing a concrete test block to be received, the detection device is used for detecting magnetic body information in the concrete test block to obtain a corresponding code of the magnetic body information, and the code information is compared with code information corresponding to an anti-counterfeiting ID in a database for verification so as to judge whether the bearing object to be received is real. As shown in fig. 1, the detection device includes a detection board and a main control board, the detection board is configured to detect magnetic substance information in a concrete test block to be sampled to obtain a corresponding binary sequence, the main control board is configured to analyze the binary sequence detected by the detection board and send an analysis result to the cloud server through the wireless communication module, and compare the analysis result with data in a database of the cloud server, and the comparison result is received by the main control board through the wireless communication module. The detection board comprises an implant detection unit and a shift register, wherein the implant detection unit is an array circuit consisting of a plurality of Hall elements and is used for detecting information of a magnetic body in a concrete test block to be sampled and converting the information into high/low level signals; the shift register is used for converting the high/low level signals converted by the implant detection unit into corresponding binary sequences to be output. The main control board comprises a wireless communication module and a data processing module, and the wireless communication module is used for realizing the communication between the sample collecting device and the server; the data processing module is used for analyzing the binary sequence output by the shift register according to the encoding rule of the anti-counterfeiting ID to obtain the encoding information in the concrete test block to be sampled, and sending the encoding information to the server through the communication module to compare and verify the encoding information with the encoding information of the anti-counterfeiting ID corresponding to the concrete test block stored in the database of the server so as to judge whether the concrete test block to be sampled is real or not and receive the judgment result of the server.

In the above embodiment, the detection board is composed of a hall element array circuit and a shift register, and is responsible for detecting the existence of the magnetic body and sending signal data to the main control board; the main control board comprises a data processor and a wireless communication module and is responsible for analyzing the signal data according to a specific rule, obtaining the code of the concrete test block after analysis, transmitting the code to the cloud server through the wireless communication module for comparison, sending the comparison result to the data processor, and controlling a peripheral screen and a loudspeaker to make a corresponding sample collection prompt by the data processor. The Hall element array circuit is formed by arraying a plurality of Hall elements according to a certain rule, wherein the rule is a coding rule corresponding to the anti-counterfeiting ID in the server, and the quantity and the array form of the Hall elements can be selected in various ways, such as a square array, a circular array, a special-shaped array and the like, according to different coding rules; for convenience of explanation, the present invention uses an example of a4 × 4 matrix arrangement as shown in fig. 2, and it should be noted that the arrangement is only used for explaining the present invention and is not used to limit the present invention; as shown in fig. 2, the hall element array circuit is a4 × 4 square array arrangement circuit, correspondingly, the magnetic bodies on the surface of the concrete test block detected by the hall element array circuit are also arranged in an array according to the rule, 16 hole sites are also arranged on the surface of the concrete test block according to the array, and then the magnetic bodies are implanted into the concrete. When the Hall device body induces the magnetic body, a low level signal is output to the shift register, wherein the low level is represented by 0; when the Hall device body does not sense the magnetic body, a high level signal is output to the shift register, wherein the high level is represented by 1; of course, the high and low levels may be opposite depending on the type of the hall device or the parameters, that is, the high level 1 may be output when the magnetic substance is detected, and the low level 0 may be output when the magnetic substance is not detected. According to the working principle of the shift register, the shift register can serially arrange and output signals input by the Hall according to a fixed sequence, the output data is a binary sequence of 0 and 1, and the sequence is transmitted to the data processor for processing and identification. As shown in fig. 2, for a total of 16 hall elements, it should be noted that the numbers of the hall elements may be random, the output rule of the shift register may also be set arbitrarily, as long as the output rule conforms to the coding rule, and the numbers of the hall elements are respectively as follows: a1, A2, A3, A4, Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10, Q11 and Q12, wherein the output rule of the shift register is set to output binary sequences corresponding to Hall element input signals in the following order: a1 → a2 → A3 → a4 → Q1 → Q2 → Q3 → Q4 → Q5 → Q6 → Q7 → Q8 → Q9 → Q10 → Q11 → Q12, the concrete block implanted with the magnetic substance (black dot represents magnetic substance) arranged in the array as shown in fig. 3 is detected by a detection board including the hall element array circuit, and the shift register serially outputs a binary sequence corresponding to 16 bits 0 or 1 according to the detection of the hall elements.

According to an embodiment of the invention, the reading and processing of the detection data of the hall element array circuit adopts an origin positioning design, taking the example shown in fig. 2 and 3 as an example, the position corresponding to a1 in fig. 2 in fig. 3 is an origin position, the magnetic body corresponding to the coding starts from the position corresponding to a1 every time, the origin position corresponding to a1 always has a magnetic body as an origin identifier, the positions corresponding to a2, A3 and A4 do not have a magnetic body, the positions corresponding to hall elements Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10, Q11 and Q12 determine whether corresponding magnetic bodies exist according to the coding rules, taking the coding information as 1011000100111 as an example, clockwise skip coding rules are adopted, the skip coding rules mean that the hall element corresponding positions except for origin coding 1 are numbered with the rest coding information and hall elements corresponding positions except for four corners (a1, a2, A3 and A4), in this example, the origin is 1, there is a magnetic body, and then the subsequent codes in the example are subjected to magnetic body coding in the order of the jump positions, i.e., the order of the hall element Q2 → Q4 → Q6 → Q8 → Q10 → Q12 → Q1 → Q3 → Q5 → Q7 → Q9 → Q11 corresponding positions, where the position corresponding to code 1 has a magnetic body, the position corresponding to code 0 has no magnetic body, and the magnetic bodies coded last are arranged as shown in fig. 3. Based on the above rule, bit skip reading is also adopted when magnetic information is analyzed. After receiving the 16-bit binary sequence output by the shift register, the data processor firstly reads the data of the original point, then reads the data corresponding to the Hall elements at other positions according to the coding rule from the original point, and finally obtains the coding information. In the actual operation process, one side of the concrete test block implanted with the magnetic bodies is randomly placed on the detection plate, and the fact that the original point position of the magnetic bodies is corresponding to the A1 Hall element cannot be guaranteed, therefore, in order to facilitate detection of the concrete test block, a user can place the concrete test block without distinguishing directions, the side where the detection plate implanted with the detection unit is placed is rotated by 90 degrees at will with the plane where the detection plate implanted with the detection unit is located as a horizontal plane, namely, the concrete test block can be detected when placed in four directions, the Hall A1, A2, A3 and A4 in four corners are set as original point detection Hall in the coding rule, meanwhile, the concrete test block only allows one corner to have the magnetic bodies in four corners, and therefore, when the concrete test block is placed in any one direction, the original point can be identified, namely, the magnetic bodies are detected by any one of the four Hall elements A1, A2, A3 and A4. The data processor reads the data 1 of the origin, and then reads the data according to the encoding rule corresponding to the anti-counterfeiting ID, such as clockwise, anticlockwise, skip bit reading and the like, by taking the origin as the starting point. It should be noted that, since there is only one origin at each of the four corners, once the origin data is read, the data of the three remaining origins detecting the hall will not be read.

According to the example of fig. 3, setting a1, a2, A3 and a4 as the origin detection hall, the data processor adopts the clockwise skip reading rule; if the data read out from A1 is 1, the original point of the magnetic code in the concrete test block is opposite to the A1 Hall element, the binary sequence output by the shift register to the data processor is shown in Table 1,

TABLE 1

Hall number	A1	A2	A3	A4	Q1	Q2	Q3	Q4	Q5	Q6	Q7	Q8	Q9	Q10	Q11	Q12
																	Register sequential output	1	0	0	0	1	0	0	1	0	1	1	0	1	0	1	0

According to the encoding rule, when data is analyzed, the data is read by jumping bits clockwise from the origin, and the reading sequence when the data processor analyzes is as follows:

a1 → Q2 → Q4 → Q6 → Q8 → Q10 → Q12 → Q1 → Q3 → Q5 → Q7 → Q9 → Q11, the data read is: 1011000100111, respectively;

if the a2 data is read to be 1, the magnetic encoding shown in fig. 3 is rotated by 90 degrees, the origin of the magnetic is rotated to face the a2 hall element, and thus, the binary sequence table 2 of the shift register output to the data processor shows:

TABLE 2

Hall number	A1	A2	A3	A4	Q1	Q2	Q3	Q4	Q5	Q6	Q7	Q8	Q9	Q10	Q11	Q12
																	Register sequential output	0	1	0	0	1	0	1	0	0	1	0	1	0	1	0	1

According to the encoding rule, when data is analyzed, the reading is carried out by jumping bits clockwise from the origin, the reading sequence when the data processor analyzes is A2, and the reading sequence is as follows:

a2 → Q4 → Q6 → Q8 → Q2 → Q11 → Q9 → Q3 → Q5 → Q7 → Q1 → Q10 → Q12, the data read is: 1011000100111.

as can be seen from the above example, after the concrete test block is rotated by 90 degrees, the data read by the data processor according to the above rule are the same, and in the same way, it can be verified that the data obtained by rotating the concrete test block by 180 degrees and 270 degrees on the basis of fig. 3 are also the same; therefore, the concrete test block can be placed into the detection plate at any 90 degrees in the horizontal direction, the code of the concrete test block can be normally detected and identified, and the detection efficiency is improved by the design.

If the server is successfully connected, a specific sampler with authority is used for operating, verification information such as a two-dimensional code is displayed on the display screen 2, the two-dimensional code comprises ID information of the sampler and is used for identity verification of a login sampler, and the sampler can log in by scanning the two-dimensional code through an APP; if the server fails to connect, a corresponding information prompt of the connection failure is displayed on the display screen 2. After the sample collecting device is successfully connected with the management system, a sample collector operating the sample collecting device logs in the management platform App by using the account and the password, scans the two-dimensional code on the display screen of the sample collecting device by using the code scanning function provided by the APP, reads the device ID contained in the two-dimensional code, and sends the device ID together with the login information of the current APP to the server for identity verification.

Wherein, the concrete test block of the arbitrary specification that accords with building industry standard all can put into the pick-up plate and detect, and the person of receiving the appearance can fix the concrete test block through changing the panel and adjusting the reference column. For convenient operation, receive appearance device and set two kinds of common specifications of 100mm and 150mm to default specification, to the test block of these two kinds of common specifications, receive appearance person need not to adjust the reference column, can directly put into the test block of pick-up plate with the test block that corresponds the specification and detect, improved and received appearance person's work efficiency, if need receive other specifications of appearance, then need replace the panel and adjust reference column 1. After identifying the code corresponding to the magnetic body in the concrete test block, the code of the concrete test block is directly uploaded to a background server, the server receives the code corresponding to the test block, the code is used as an index, important information such as items, mark sections and the like of the test block is retrieved and verified, meanwhile, relevant query is carried out on records corresponding to the sampling and maintenance stages of the test block, maintenance information of the test block is verified, and authenticity and uniqueness of the concrete test block are confirmed. And when all the information is verified to be correct, the cloud server can issue a result of the correct verification to the sampling client. After receiving the result, the sample collection equipment can prompt that the sample collection is successful in a voice broadcasting mode. If the information is not verified, the sample receiving equipment prompts 'sample receiving failure' in a voice mode, and corresponding failure reasons are displayed on a display screen of the sample receiving equipment, such as 'the test block code is wrong', 'the test block does not accord with the item information', and the like. The sampling result can be recorded into a sampling result library appointed by the server, and a sampler or related personnel can check the sampling result and the detailed information of the test block through a management platform or a corresponding App.

By adopting the sample collecting device, the bearing object is directly placed on the panel, and the surface implanted with the implant body is opposite to the detection device, so that automatic sample collecting identification can be completed, not only can anti-counterfeiting verification be effectively carried out, but also the sample collecting efficiency can be obviously improved, and the error rate of manual sample collection is reduced.
