Description

Technical Field

[0001] The present invention relates to the field of key bolt anti-loosening monitoring for harvesters, and in particular to an intelligent monitoring system and method for a bolt connection anti-loosening early warning device. Background Art

[0002] Bolts are common mechanical connection elements, crucial in engineering and manufacturing. They provide essential support and assurance for the proper functioning of mechanical equipment through functions such as connection, disassembly, adjustment, force transmission, and loosening prevention. In everyday life, bolts are most fundamentally used to connect various materials. They embed the threaded portion into the objects being connected, leveraging the friction and tightening force of the threads to securely fasten two or more objects together. This connection is also removable, making repair, replacement, and adjustment more convenient.

[0003] Bolts in agricultural machinery like harvesters are exposed to high temperatures and high vibrations for extended periods, causing them to expand and contract, which reduces the friction of the bolt threads. Over time, the bolts and threads may wear and corrode, causing the threads to loosen. Furthermore, if exposed to vibrations for extended periods, the bolts may fall out due to external forces. When bolts in critical locations loosen, the impact on a device or even an entire machine can be devastating, potentially causing the entire machine to collapse.

[0004] The existing technology for bolt loosening detection has the following shortcomings: it is impossible to monitor a large number of bolt devices, and the existing monitoring devices are all disposable devices with low replaceability and reusability, and cannot be used multiple times or replaced. The existing bolt monitoring devices have poor adaptability to bolts of different sizes, and one device cannot monitor bolts of various sizes. There is no corresponding coding processing for the loose bolt information. When the number of bolts is too large, it is difficult for the system to identify the loose bolt information. Summary of the Invention

[0005] To address the above technical issues, the present invention provides an intelligent monitoring system for a bolt connection anti-loosening warning device. This device can adapt to the installation and loosening monitoring of bolts of different sizes and shapes. This monitoring system reduces the cost of monitoring bolts of different sizes and shapes while significantly improving the adaptability of the bolt anti-loosening device to anti-loosening monitoring of different bolts on various machines. The intelligent monitoring system for bolt connection anti-loosening warning devices described in the present invention can simultaneously monitor the loosening of a large number of bolts on multiple pieces of equipment.

[0006] The present invention also provides a control method for the intelligent monitoring system of the bolt connection anti-loosening warning device, which can realize the anti-loosening monitoring of multiple bolts by multiple monitoring devices at the same time. Different devices send different information codes when detecting loose bolts, so that staff can accurately find the location of the loose bolts through the code.

[0007] This invention improves the safety and stability of harvesters when used in bolt anti-loosening monitoring applications. It is beneficial for the development of high-quality, intelligent monitoring for harvesters, as well as for their safety and service life. It also reduces the cost of harvester safety monitoring and improves monitoring efficiency for harvesters with large spans, thus having significant implications for harvester construction.

When the bolt is loosened, the bolt adapter ring drives the circuit rotation connection mechanism to rotate, so that the monitoring box matching circuit and the circuit rotation connector touch and connect, the monitoring device circuit is connected and the pressure information and coding information are sent to the short-range data monitoring station.

[0014] Furthermore, the bolt adapter ring has multiple models, and the wall thickness of the inner wall of the bolt adapter ring can be set to different thicknesses, so that the circuit rotation connection mechanism can cooperate with bolt heads of different models and sizes through bolt adapter rings of different thicknesses.

[0017] When the two diagonal circuit rotary connectors and the monitoring box are connected, the monitoring device circuit power supply circuit will be connected. In the above scheme, the monitoring device circuit includes a pressure sensor adjustment bolt, a signal transmission antenna, multiple A / D adjustment potentiometers, a power supply button battery, a circuit power supply circuit, a device information processing center, a pressure monitoring plate, and a pressure monitoring plate circuit;

[0018] The pressure sensing piece adjustment bolt is connected to the screw hole built into the monitoring device circuit, and the end is connected to one side of the pressure monitoring piece for adjusting the height of the pressure monitoring piece; the signal transmitting antenna is located on one side of the device information processing center for signal transmission; the built-in circuit of the A\D adjustment potentiometer is connected to the built-in A / D interface of the device information processing center for setting different potentials for encoding; the power supply button battery is connected to the device information processing center through the circuit power supply circuit; the other side of the pressure monitoring piece is connected to the device information processing center through the pressure monitoring piece circuit, and the pressure monitoring piece is used to detect the pressure information given by the bolt.

[0019] Furthermore, the coding information of the A / D adjustment potentiometer is obtained by:

[0020] Multiple A\D adjustment potentiometers are named respectively and connected to the A\D interface of the device information processing center through circuits. The different digital levels of the A\D adjustment potentiometers make the A\D interfaces of the A\D adjustment potentiometers read different voltages after power is turned on, forming different coding information corresponding to different bolts. The device information processing center detects the A\D values ​​of different A\D adjustment potentiometers and sends out different bit information.

[0021] Furthermore, the number of the A / D adjustment potentiometers is four, and each A / D adjustment potentiometer is provided with 12 levels;

[0022] The four A\D adjustment potentiometers are named potentiometer A, potentiometer B, potentiometer C, and potentiometer D, and are connected to the A\D interface of the device information processing center through circuits. The different bit levels of the A\D adjustment potentiometers make the voltages read at the A\D interfaces of the A\D adjustment potentiometers different after power is turned on.

There are a total of 12*12*12*12=20736 four-digit information. 20736 coded information can be set to monitor and warn 20736 bolts.

[0073] The present invention can replace different bolt adapter rings 301, and at the same time, the coding information of the monitoring device circuit 305 is adjustable, so that the bolt loosening monitoring device 3 can monitor bolts of different sizes; in a specific embodiment of the present invention, the bolt loosening monitoring device 3 is provided with four 12-bit adjustable coding devices, which can realize 20736 different four-bit coding information, so that one device can realize 20736 types of information coding, and realize different bolts to be monitored by devices with different codings, so as to determine which bolt is loose; after the loosening alarm occurs, the device can be reused by manually adjusting the device and replacing the battery, thereby improving the replaceability and reusability of the bolt monitoring device.

[0074] like Figure 11 As shown, preferably, the short-range data monitoring station 4 is installed on the most central of the multiple harvesters 1 within the monitoring range, and is used to monitor the harvesters in a short farm range; the data recording and uploading processing center 5 is installed at the edge of the field of the harvester 1 to be monitored; the harvester monitoring and processing station 6 is installed on one side of the data recording and uploading processing center 5, which is convenient for staff to manage more harvesters; the cloud service monitoring platform 7 can be installed in the server of the farm monitoring center.

[0075] like Figure 12As shown, data can be transmitted between the short-range data monitoring stations 4, and the central harvester 1 installed on multiple harvesters 1 monitors the bolt anti-loosening warning devices on all harvesters in a radial form; the data record upload processing center 5 can accept information processing from a single or multiple short-range data monitoring stations 4; the cloud service monitoring platform 7 uploads the data to the cloud server, and the harvester monitoring processing station 6 can read the data on the cloud service monitoring platform 7. If there are loose bolts, a maintenance instruction will be issued to facilitate maintenance personnel to handle it.

[0076] In a specific embodiment of the present invention, by adjusting the four-bit code of the bolt anti-loosening warning device, each four-bit code corresponds to each bolt that needs to be monitored for anti-loosening, and then the adjusted bolt anti-loosening warning device is installed in the harvester 1, and the short-range data monitoring station 4 is installed in a harvester 1 in the center of multiple harvesters 1. The short-range data monitoring station 4 on the central harvester 1 radially monitors all bolt anti-loosening warning devices 3 on the harvesters 1 within the nearby range; the data record upload processing center 5 receives data from the short-range data monitoring station 4, and uploads the data to the cloud service monitoring platform 7, and the harvester monitoring processing station 6 obtains data from the cloud service monitoring platform 7.

[0077] In a specific embodiment of the present invention, the pressure monitoring piece 305-7 of the monitoring device circuit 305 is connected to the device information processing center 305-6 through the pressure monitoring piece circuit 305-8, and the pressure monitoring piece circuit 305-8 has extra length to accommodate the adjustment of the pressure monitoring piece 305-7. By adjusting the pressure sensing piece adjusting bolt 305-1, the pressure monitoring piece 305-7 can be adjusted to contact the monitored harvester bolt 2 on the inner side of the circuit rotary connector 302, which can adapt to the anti-loosening monitoring of nuts or screws of different heights. When the bolt anti-loosening warning device 3 starts working, the device information processing center 305-6 will continuously send the pressure of the pressure monitoring piece 305-7 together with the four-digit code to the short-range data monitoring station 4. The larger the value monitored by the pressure monitoring piece 305-7, the faster the frequency of sending loosening information to the short-range data monitoring station 4, reminding the system and staff of the degree of bolt loosening.

[0078] The present invention sets up a short-range data monitoring station 4, which can transmit the loose bolt information on multiple machines to a single short-range communication device, and finally transmit it to the data record upload processing center 5. The cloud service monitoring platform 7 uploads the data to the cloud server. The harvester monitoring and processing station 6 can read the data on the cloud service monitoring platform 7 and notify manual processing of the loose bolts. The present invention improves the replaceability and reusability of the monitoring device, and improves the safety and stability of the harvester in the application of the harvester.

[0079] When the intelligent detection system of the bolt connection anti-loosening warning device starts working, the bolt loosening monitoring device 3 installed on the bolt that needs to be prevented from loosening is always in a power-off state to reduce the energy loss of the bolt loosening monitoring device due to long-term power supply. When the monitored bolt loosens and rotates, the bolt loosening monitoring device 3 will be powered on, and the generated tiny electrical signal will be transmitted to the internal device information processing center 305-6 of the bolt loosening monitoring device through the amplification circuit. After receiving the signal, the wireless small signal transmitting device signal transmitting antenna 305-2 of the bolt loosening monitoring device 3 will send the loosening information to the short-range data monitoring station 4, and the built-in recorder of the short-range data monitoring station 4 will record the loosening information. The module records the data, and the built-in data transmission module transmits the information to the data record upload processing center 5. The information processing module built into the data record upload processing center 5 then uploads the data records to the harvester monitoring and processing station 6 and the cloud service monitoring platform 7. This allows the harvester monitoring and processing station 6 to learn about the loose bolts, facilitating the dispatch of personnel to repair the loose bolts. At the same time, the loosening information of the harvester bolts is also uploaded to the cloud service platform. The cloud service can record and calculate the number of harvester bolts in the area, the pressure at the time of loosening, the loosening frequency, the loosening time, the temperature, etc., which helps to remind users which harvesters are prone to loosening due to environmental factors. This system improves the development of high-quality, intelligent monitoring of harvesters, the safety performance and service life of harvesters, while also reducing the cost of harvester safety monitoring. It can achieve monitoring efficiency for large-span harvesters and is of great significance to harvester construction.

When the harvester bolt 2 loosens and rotates, it drives the bolt adapter ring 301 to rotate. The rotation of the bolt adapter ring 301 will drive the circuit rotary connector 302 to rotate, so that the circuit rotary connector 302-2 on the circuit rotary connecting leaf 302-1 is connected to the monitoring box matching circuit 306-2 in the built-in groove 306-1 of the monitoring box, and the monitoring circuit The power supply circuit is connected, and the device information processing center 305-6 of the monitoring device circuit 305 reads the pressure of the bolt detected by the pressure monitoring piece 305-7 at this time, and obtains the four-bit coding data of the four A\D adjustment potentiometers 305-3. The device information processing center 305-6 sets the information transmission frequency according to the pressure value of the pressure monitoring piece 305-7. The device information processing center 305-6 transmits the pressure information and coding information to the short-range data monitoring station 4. The short-range data monitoring station 4 transmits the pressure information and coding information to the data record upload processing center 5. The data record upload processing center 5 uploads the pressure information and coding information to the cloud service monitoring platform 7. The harvester monitoring and processing station 6 reads the pressure information and coding information of the cloud service monitoring platform 7, and issues a warning signal to remind the staff to deal with the loosened bolts.
