The hydraulic torque wrench 2 is provided with an electronic reading and writing device 5 for reading and writing the electronic tag 4, a parameter acquisition unit 6 for acquiring the screwing process parameters of the bolt and nut 1, and a starting timer 7 for calculating the starting time of the hydraulic torque wrench 2; after the hydraulic torque wrench 2 is started, the electronic reading and writing device 5 collects the identification codes of the bolt and nut 1 in the electronic tag 4, the parameter collection unit 6 collects the screwing process parameters of the bolt and nut 1, the screwing timer records the starting time of the hydraulic torque wrench 2 and then uploads the starting time to the cloud platform 3 after the starting time is correlated, the cloud platform 3 is internally provided with a parameter detection unit for detecting the screwing process parameters of the bolt and nut 1 uploaded by the parameter collection unit 6, if the starting time is not consistent with the set standard value, the alarm prompt unit of the cloud platform 3 sends an alarm prompt, and the alarm prompt can be a display prompt and/or an acousto-optic prompt.
The technical scheme is specifically described by combining the embodiment as follows:
firstly, the nut identity card is established by adopting the following three methods.
1. Electronic label 4
a. Carrying a unique nut identification code by using a bar code or a two-dimensional code;
b. carrying a nut unique identification code by using an anti-Metal NFC chip (On-Metal NFC);
c. and (4) directly stamping relevant information and a serial number on the surface of the nut by using an OCR/OCV technology reading manufacturer.
The common point of the above a and b is that a system identification code generator is required, the identification code generator generates identification codes which include nut manufacturer information and also carry identification information for the wind turbine engine room, the generator, the hub, the blade, the multiple sections of towers and the like, and the system identification code generator finally prints identification codes (steel seal) or embeds electronic tags 4. Therefore, the relationship between the identification code (electronic tag 4) and the bolt nut 1 (or other fan devices) is independent of each other. After the identification code is generated, the identification code needs to be manually pasted on the bolt nut 1, and the optimal scheme of the embodiment is that the NFC chip embedded with the identification code needs to be manually pasted on the top of the specified bolt. This pasting operation is an additional influence (one-step process flow is added) on the production process flow by introducing an informatization system. And the c is integrated in the production process of the bolt and nut 1 manufacturer, a system identification code generator is not needed, and the pasting operation is not needed.
The above a has no technical bottleneck, but when the bolt and nut 1 is placed in the fan nacelle (after manual operation), the operator needs to input the 'identity' of the bolt and nut 1 into the system (cloud platform 3) by scanning the code with the portable code scanning machine, and the position of the bolt and nut 1 can be determined.
The operation process can be intelligentized, the hydraulic torque wrench 2 is required to be provided with an NFC card reader (an electronic read-write device 5) carrying a communication module, in actual operation (in the process of screwing the bolt and nut 1), the identity and the operation information of the bolt and nut 1 are pushed to the cloud platform 3 in real time through the NFC card reader, the distance for the card reader to read data in an NFC chip in a non-contact mode must be within five centimeters (5cm), and specific use methods of the NFC card reader and the hydraulic torque wrench 2 can be discussed in subsequent chapters. The NFC chip carrying the nut identification card is an optimal technical solution in this patent embodiment, and its bright spot is the interactivity using the NFC technology, and the NFC chip on the bolt and nut 1 not only represents its identity, but also can acquire code reader information (such as the current torque) and feed it back to a subsequent reading event (such as screwing the bolt and nut 1 again), and in addition, the device will be docked with a robot data interface, and bind its operating data (torque, time, nut position) and the nut identity (identification code) and upload it to the cloud platform 3.
The OCR/OCV in the step c is a method for quickly identifying images by optical imaging, the technology is mature and widely applied, the accuracy rate of normal environment is more than 99%, particularly, an identification code printed on the surface of a nut by steel can be effectively identified and obtained on an automatic production line, the only requirement is to ensure that the surface of the bolt nut 1 is clean and smooth, the image identification difficulty is avoided, the environment built by a fan is poor, dust and sand are blown out, and the steel print on the surface of the nut is easy to be unclear.
2. Electronic read-write equipment
The electronic read-write equipment acts on the contactless read-write communication equipment of the electronic tag 4, and the electronic read-write equipment is different according to the type of the electronic tag 4, and the electronic read-write equipment needs to be arranged at a proper position of the hydraulic torque wrench 2 (the following sections will be described in detail).
If be used for reading and writing the NFC read write line of NFC chip, its inside MCU treater, WIFI module, state display module, torque sensor, modules such as receiver, power of being equipped with, the MCU treater is equallyd divide and is do not coupled modules such as WIFI module, state display module, torque sensor, receiver, power, and the antenna is connected in the receiver coupling.
And Optical Character Recognition (OCR) and Optical Character Verify (OCV) mature technique as the instrument, and the instrument can read bolt nut 1 manufacturer embossed seal identification code on bolt nut 1 fast to analyze out the identification code, the nut number will bind the operating data, upload to cloud platform 3 through the communication module (the bridging net cloud) that integrates.
Secondly, a concrete implementation method of the electronic tag 4 carrying the identification code of the bolt and nut 1 is arranged on the bolt and nut 1, the bolt is taken as an example in the embodiment, and the concrete scheme is as follows:
the bolt identification code needs to be written into the electronic tag 4 in advance, the NFC chip is taken as an example below, the process of writing the nut identification code into the NFC chip is specifically described, any NFC chip has an initial and unique fixed UID, the whole writing process is completed in the environment of a server (server) of a fan factory and an NFC card reader, the UID of the NFC chip has uniqueness and can be the identification code of the bolt and nut 1, the code with the production tracing meaning such as a manufacturer number and a batch number can be added into the identification code of the bolt and nut 1, and the tracing query is convenient for the bolt and nut 1 to go wrong.
Thirdly, a parameter acquisition unit 6 for acquiring the screwing technological parameters of the bolt and the nut 1
Parameter acquisition unit 6 includes the moment of torsion and gathers the subelement, be used for gathering the moment of torsion parameter of applying on bolt nut 1 according to the frequency of setting for after hydraulic torque wrench 2 starts, gather in frequency accessible high in the clouds sets for back write in parameter acquisition unit 6, hydraulic torque wrench 2's execution end is equipped with torque sensor, directly record the torque value of applying on bolt nut 1, gather the torque value according to the frequency of setting for after hydraulic torque wrench 2 starts, and upload to host computer 9, host computer 9 can be ground station or high in the clouds, host computer 9 detects the torque value, if the torque value is less than the torque value of setting for, or not satisfy the qualification duration, be greater than the torque value of setting for and be greater than duration, host computer 9 sends the warning suggestion, the staff can remind field operation personnel, do rework and remedy.
The parameter acquisition unit 6 comprises a pressure acquisition subunit, the pressure parameters applied to the contact surface of the bolt nut 1 are acquired according to set frequency after the hydraulic torque wrench 2 is started, the torque value or the axial force applied to the bolt nut 1 can be calculated through the pressure parameters, the acquisition frequency can be written into the parameter acquisition unit 6 after being set through a cloud, the execution end of the hydraulic torque wrench 2 is provided with a plurality of pressure sensors which are annularly distributed, the pressure value can be detected through the pressure parameters, the contact surface between the hydraulic torque wrench 2 and the nut belongs to point contact, line contact or surface contact, whether the torque value is qualified or not is checked, if the torque value is not in point contact or surface contact, the pressure value is overlarge, the upper computer 9 sends an alarm prompt, and a worker can remind field operators to perform rework remediation.
The parameter acquisition unit 6 comprises a frequency setting subunit and is used for setting the parameter acquisition frequency for acquiring the screwing technological parameters of the bolt nut 1 by the parameter acquisition unit 6 after the hydraulic torque wrench 2 is started, receiving the frequency set value sent by the upper computer 9 and covering the current acquisition frequency. When the hydraulic torque wrench 2 is started, the parameter acquisition unit 6 is controlled to acquire parameter values according to a set frequency.
The parameter acquisition unit 6 comprises a process frequency subunit, and is used for weighting the frequency item of the identification code of the current bolt and nut 1 after the hydraulic torque wrench 2 is started. In this embodiment, the number of times is 3, namely, it is necessary to screw the same bolt and nut 1 at least 3 times, and in the processing of the wind turbine tower, because the connection surface between the wind turbine tower is too huge, the amount of required connecting pieces is large, and therefore, in order to balance the internal stress of the connection surface, the nut is screwed by using a cross diagonal method, and each nut needs at least 3 times. The hydraulic torque wrench 2 reads the identification code of the bolt and nut 1 in the electronic tag 4 after being started, the upper computer 9 weights the times of the identification code of the bolt and nut 1, if the weighted weight of the times is lower than 3, the upper computer 9 sends out an alarm prompt, and a worker can remind a field operator to perform rework remediation.
After the cloud acquires the parameters, the combination of the multiple parameters can be carried out through combining a corresponding inspection algorithm to carry out accurate detection, so that the type of unqualified types can be deduced, if the using torque is qualified, but the starting time is unqualified, the system deduces that the bolt and nut 1 is not screwed down by field workers, or if the torque is qualified, the starting time is qualified, but the pressure is overlarge, the contact surface of the hydraulic torque wrench 2 and the nut is in line contact, and the coincidence of the two is unqualified, so that the bolt and nut 1 needs to be inspected, and the like, different problem conditions are displayed by the cloud aiming at each bolt and nut 1 through different colors, so that monitoring personnel can accurately know the field construction conditions, the inspection working efficiency is greatly improved, and the construction cost is reduced.
The electronic reading and writing device 5 can write the screwing process parameters of the bolt and nut 1 acquired by the parameter acquisition unit 6 and the starting duration of the hydraulic torque wrench 2 recorded by the starting timer 7 into the electronic tag 4, and stores the acquired parameters such as the torque value, the pressure value, the time point, the number item weight, the frequency value and the like into the electronic tag 4 in the form of data blocks, and sorts the parameters according to the time point, so that the scanning and the checking of later-stage detection personnel are facilitated.
Fourth, alarm
And if the identification code of the bolt and nut 1 is not acquired before the hydraulic torque wrench 2 starts screwing the nut, the hydraulic torque wrench 2 sends out an alarm prompt. Due to some reason, the electronic tag 4 falls off, but the nut can still be used, and the cloud platform 3 can give an early warning to the nut according to the received alarm signal, inform field supervision personnel, and can make up (patch the falling chip) at any time in the assembling acceptance or future operation and maintenance process and re-register. The operation process of the nut is bound with the new identity and cannot be lost. Or, because the fan job site all is in the place that people are rare such as open air, wilderness, so the signal transmission environment is not very good, in order to improve the accuracy of reporting to the police, can send the alarm signal to the ground station, and the ground station reports to the police, or the ground station sends the alarm signal to cloud platform 3 and reports to the police to and compensate the problem that the label drops in time.
Five, hydraulic torque wrench 2
The hydraulic torque wrench 2 is any one of a driving shaft hydraulic torque wrench 2, a hollow hydraulic torque wrench 2 or a tensioning wrench, and the electronic tag 4 is arranged at the top of the nut; wherein, the drive shaft hydraulic torque wrench 2 or the tensioning method tightening wrench, and the read-write end of the electronic read-write device 5 is arranged at one side or two sides of the drive shaft hydraulic torque wrench 2; the hollow hydraulic torque wrench 2 and the electronic reading and writing end of the electronic reading and writing device 5 are arranged at the top cavity opening of the hollow screwing cavity.
a. As shown in fig. 3a, the drive shaft hydraulic torque wrench 2 or the tension wrench will be covered by the tightening nut and the code reader cannot directly obtain the identity of the nut. Therefore, the identities of the left and right (front and back) adjacent nuts of the bolt and nut 1 are read, and the identities of the left and right adjacent nuts are continuously read (more than twice), so that the identities of the covered nuts can be calculated.
b. As shown in fig. 3b, the hollow hydraulic torque wrench 2 exposes the top of the nut so that the electronic reader/writer 5 can directly read the identity of the tightened nut.
Different card reader supports can be designed for different types of hydraulic torque wrenches 2, the card reader supports do not hinder the normal use of the hydraulic torque wrenches 2 by operators, and the electronic reading and writing device 5 is fixed under the condition of not introducing additional operation programs or burdens.
The hydraulic torque wrench 2 comprises an electric hydraulic pump with a digital hydraulic sensor and a communication module, the electric hydraulic pump is used for providing torque for the hydraulic torque wrench 2 to tighten nuts, pressure is generally set once, and the hydraulic torque wrench 2 can perform tightening operation by taking five continuous bolt nuts 1 as units according to an operation process (a cross diagonal method) until the whole process is completed. And setting the pressure of the next torque according to the requirement, and repeating the steps. The uploaded pressure data is likely to be a constant over a period of time, and for the bound bolt and nut 1, only the pressure at a certain point in time is concerned, so that the tightening torque can be calculated.
The hydraulic torque wrench 2 may also be equipped with a stress sensor and upload the torque of the tightened nut as the nut identity binding through the hydraulic torque wrench communication module 10. The hydraulic torque wrench 2 stress sensor may also act as a switch for a triggering event (reading the nut identification code and associated operational flow data).
Sixth, fan data acquisition communication scheme
As shown in fig. 4, according to the scheme, a local area network is arranged in a fan assembly area, so that the condition that a wind field network signal is weak or absent is avoided, when the identity of a screwed bolt and nut 1 and related operation processes (a plurality of communication module uploading nodes) respectively upload data, the data are in a communication process from a 'child-level' communication module to a 'parent-level' ground station, and the communication of the local area network is not influenced by the network signal. Data are uploaded to the ground station according to the triggering event, the ground station can upload the data to the cloud platform 3 in real time according to the network signal condition, if the signal is not good, the ground station serves as a data collecting center to play a role in temporary storage, when the signal exists, the ground station can automatically trigger the uploading of the temporarily stored data, and the ground station can be carried about by field supervision personnel (representing fan manufacturers).
Taking the connection of the tower drum at the bottom section of the fan and the foundation ring as an example, when the pressure pump is started, the pressure is adjusted, and the pressure data is uploaded through the communication module at the moment. An operator puts the hydraulic torque wrench 2 on the screwed bolt and nut 1, and at the moment, the electronic reading and writing device 5 fixed on the hydraulic torque wrench 2 uploads the identities of the bolt and nut 1 adjacent to the screwed bolt and nut 1. And starting the hydraulic torque wrench 2 and screwing the bolt and the nut 1. When the stress sensor of the hydraulic torque wrench 2 reaches specific pressure, the switch state is triggered and uploaded through the communication module, the ground station receives the trigger state (from the stress sensor), the identity (one or two) of the nut, the pressure (torque), the time and the position (relative) are bound and uploaded, and if the signal is not good (uploading fails), the data are temporarily stored in the ground station.
The ground station is responsible for sending the torque (pressure) for tightening the bolt and nut 1 to the electronic read-write device 5, and writing the torque (pressure) into the NFC chip, and the information can provide a supervision mechanism for the next cycle (torque and pressure) of tightening the bolt and nut 1.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
