Description

Technical Field

[0001] This invention relates to the field of control technology for work machinery, and in particular to a boom position detection system, method, and work machinery. Background Technology

[0002] Existing telescopic booms of work machinery can be categorized into two types based on their telescopic mechanism: dual-cylinder rope-operated and single-cylinder pin-operated. In work machinery using a single-cylinder pin-operated boom, the cylinder barrel is equipped with a plugging / unplugging mechanism. During cylinder extension and retraction, this mechanism connects to the corresponding boom pin, thus linking the boom to the cylinder barrel. When the work machinery has multiple telescopic boom sections, it is necessary to determine which boom section the cylinder barrel is connected to during cylinder extension and retraction—that is, to obtain the boom position information—to ensure the safe operation of the work machinery.

[0003] In existing technologies, multiple proximity switches and boom position detection blocks are used in conjunction with existing ones to obtain the boom position information, implemented in binary code. This method requires a large number of proximity switches and boom position detection blocks, necessitating numerous communication cables and posing risks of interference, friction, and breakage between these cables and the detection blocks. Furthermore, during actual operation, if the boom position detection blocks fail to transmit signals to the controller synchronously, it can lead to abnormal boom control. Summary of the Invention

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0050] The following is combined with Figures 1 to 8 The arm position detection system of the present invention is described.

[0051] This invention provides an arm position detection system, such as... Figure 1 As shown, the system includes: at least one smart arm pin 101, a smart plug-in mechanism 102, and a display device 103. The smart plug-in mechanism 102 and the display device 103 are communicatively connected, and the smart arm pin 101 and the smart plug-in mechanism 102 are wirelessly connected.

[0052] The smart arm pin 101 is used to store the arm position information of the corresponding telescopic arm, wherein at least one smart arm pin 101 corresponds to one telescopic arm section.

[0053] The intelligent plug-in mechanism 102 is used to determine the arm position information of the telescopic arm that is in operation based on the intelligent arm pin 101, use the arm position information of the telescopic arm that is in operation as the target arm position information, and send the target arm position information to the display device 103.

[0054] Display device 103 is used to display target arm position information.

[0055] Specifically, the display device 103 includes a display screen that displays target arm position information.

[0056] Specifically, in addition to storing arm position information, the intelligent arm pin 101 can also store other information, including: the model and production year of the corresponding operating machinery, the model and production year of the intelligent arm pin 101, and the version information of the program stored in the intelligent arm pin 101, etc.

[0057] Specifically, users can set the intelligent plug-in mechanism 102 to determine other information about the telescopic arm that is in operation, and send the other information to the display device 103 for display, according to actual needs.

[0058] Specifically, the at least one smart arm pin 101 included in the arm position detection system refers to all smart arm pins 101 in the arm position detection system, and the at least one smart arm pin 101 corresponding to a telescopic arm section refers to all smart arm pins 101 corresponding to that telescopic arm. The number of at least one smart arm pins 101 included in the arm position detection system is the product of the number of at least one smart arm pins 101 corresponding to a telescopic arm section and the number of telescopic arm sections.

[0059] In one specific embodiment, such as Figure 2 As shown, the intelligent arm pin 101 includes a first intelligent device 201 and an arm pin body 202. The first intelligent device 201 is installed on the arm pin body 202. The first intelligent device 201 is used to store the arm position information of the corresponding telescopic arm.

[0060] Specifically, the first intelligent device 201 has a structure that is shockproof and oil-resistant. For example, the first intelligent device 201 is made of a malleable polymer material.

[0061] Specifically, depending on the type of the first intelligent device 201, the first installation position on the arm pin body 202 varies.

[0062] For example, when the first intelligent device 201 is based on a structure such as a barcode or QR code, the first intelligent device 201 is mounted on the outer surface of the shaft of the arm pin body 202, such as... Figure 3 As shown, in Figure 3 The diagram is illustrated using several thick lines; for example, when the first intelligent device 201 is based on a structure such as an intelligent ring, the first intelligent device 201 is installed within the range of the limiting ring of the arm pin body 202, such as... Figure 4 As shown, in Figure 4The diagram is illustrated using several thick lines; for example, when the first intelligent device 201 is based on a structure such as an identification card, the first intelligent device 201 is mounted on the end face of the arm pin body 202 on the same side as the limiting ring, as shown below. Figure 2 As shown, in Figure 2 The diagram is illustrated using thick lines. The identification card includes an electronic tag.

[0063] Wherein, in this invention Figure 2 The illustration is based on the example of installing the first intelligent device 201 on the end face of the arm pin body 202.

[0064] In one specific embodiment, such as Figure 5 As shown, the intelligent plug-in mechanism 102 includes: a second intelligent device 501 and a plug-in mechanism body 502. The second intelligent device 501 is mounted on the plug-in mechanism body 502. The second intelligent device 501 is used to determine the arm position information of the telescopic arm that is in operation based on the first intelligent device 201, take the arm position information of the telescopic arm that is in operation as the target arm position information, and send the target arm position information to the display device 103.

[0065] Specifically, the second intelligent device 501 is a mechanism for preventing collisions and oil stains. For example, the second intelligent device 501 is made of a malleable polymer material.

[0066] Specifically, because the first intelligent device 201 is installed in a different first mounting position on the arm pin body 202, the second intelligent device 501 is installed in a different second mounting position on the insertion and removal mechanism body 502. The second mounting position needs to correspond to the first mounting position so that the second intelligent device 501 can quickly and accurately determine the arm position information of the telescopic arm that is in operation.

[0067] Wherein, in this invention Figure 5 With Figure 2 The example of the first intelligent device 201 being installed on the end face is illustrated accordingly. Figure 5 The second intelligent device 201 is illustrated with thick lines.

[0068] In one specific embodiment, such as Figure 6 As shown, the plug-in / plug-out mechanism body 502 includes: a plug-in / plug-out structure 601 and a slot 602; a second intelligent device 501 is installed on the slot 602, and the slot 602 on which the second intelligent device 501 is installed is installed on the plug-in / plug-out structure 601.

[0069] Specifically, slot 602 is a dovetail-shaped slot, defined as a dovetail slot, which enables the intelligent arm pin 101 and the intelligent insertion / removal mechanism 102 to move stably and rapidly. Among these, through... Figure 7 This illustrates the dovetail groove.

[0070] In one specific embodiment, the first intelligent device 201 includes a passive signal generating component; the passive signal generating component includes a passive signal generating component body and a carrier recording arm position information. The second intelligent device 501 is used to detect the passive signal generating component, and when the passive signal generating component is detected, to identify the arm position information recorded on the carrier, to use the identified arm position information as target arm position information, and to send the target arm position information to the display device 103.

[0071] Specifically, passive signal generating components are components that only have storage functions and no signal transmission functions, such as components based on barcodes or QR codes.

[0072] At this point, the passive signal generating component is made of transparent, impact-resistant, and stain-resistant material, and the carrier is a barcode or QR code, with the passive signal generating component protecting the carrier. For example, the passive signal generating component is made of a malleable polymer material.

[0073] Specifically, the second intelligent device 501 has a detection function, which needs to determine whether a passive signal generating component can be detected. If no passive signal transmitting component is detected, no operation is required. If a passive signal generating component is detected, the arm position information recorded on the carrier is identified.

[0074] Specifically, the method for determining whether a passive signal generating component can be detected is as follows: the second intelligent device 501 includes a visual camera and a processor. The visual camera acquires captured images or videos, and the processor extracts features from the captured images or videos. When the features of the passive signal generating component are obtained, it is determined that the passive signal generating component has been detected. The information recorded on the carrier in the captured images or videos is identified and extracted to obtain the arm position information.

[0075] In one specific embodiment, the first intelligent device 201 includes: an active signal generating component; the active signal generating component is used to send an arm position signal, the arm position signal carrying the arm position information of the corresponding telescopic arm. The second intelligent device 501 is used to receive the arm position signals; determine the signal strength of each arm position signal; identify the telescopic arm corresponding to the active signal generating component of the arm position signal with the strongest signal strength as the telescopic arm that is currently in operation; analyze the arm position signal with the strongest signal to obtain target arm position information, and send the target arm position information to the display device 103 so that the display device 103 displays the target arm position information.

[0076] Specifically, the arm position detection system may also include a control device, which is communicatively connected to the second intelligent device 501 and the display device 103.

[0077] The control device can be a controller, such as a microcontroller unit or a chip.

[0078] The second intelligent device 501 is used to receive arm position signals; determine the signal strength of each arm position signal; identify the telescopic arm corresponding to the active signal generating component of the arm position signal with the strongest signal strength as the telescopic arm that is in operation; and send the arm position signal with the strongest signal strength to the control device; the control device is used to analyze the arm position signal with the strongest signal strength to obtain the target arm position information, and send the target arm position information to the display device 103.

[0079] Specifically, active information generating components are components with storage and signal transmission functions, such as components based on structures like smart rings, or components based on structures like identification cards, etc.

[0080] Specifically, the second intelligent device 501 of the present invention can simultaneously receive multiple arm position signals and process the multiple arm position signals simultaneously.

[0081] For example, if eight arm position signals are sent to the second intelligent device 501 at the same time, the second intelligent device 501 can simultaneously determine the signal strength of each arm position signal.

[0082] For example, if six arm position signals are sent to the second intelligent device 501 at the same time, the second intelligent device 501 can simultaneously determine the signal strength of each arm position signal.

[0083] For example, if four arm position signals are sent to the second intelligent device 501 at the same time, the second intelligent device 501 can simultaneously determine the signal strength of each arm position signal.

[0084] Specifically, the operating telescopic boom is identified using Received Signal Strength Indication (RSSI) technology. The RSSI value directly reflects the distance between the first intelligent device 201 and the second intelligent device 501. Therefore, the operating telescopic boom can be determined by measuring the RSSI value. Since the first intelligent device 201 corresponding to the operating telescopic boom is closest to the second intelligent device 501, its RSSI value is the highest, indicating the strongest signal strength.

[0085] In one specific embodiment, the first intelligent device 201 includes: an active signal generating component; the active signal generating component is used to send an arm position signal, the arm position signal carrying the arm position information of the corresponding telescopic arm; the second intelligent device 501 is used to receive the arm position signal; and execute the following signal strength determination strategy: if it is determined that the number of arm position signals received at the current time is greater than a first preset number, a delay command is sent to a second preset number of active signal generating components, and the signal strength of the arm position signals corresponding to the first preset number of active signal generating components is determined, and a sleep command is sent to the first preset number of active signal generating components, wherein the second preset number is less than the number of signals, and the first preset number is the difference between the number of signals and the second preset number; the signal strength determination strategy is repeatedly executed until the signal strength of each arm position signal is determined; the telescopic arm corresponding to the active signal generating component of the arm position signal with the strongest signal strength is taken as the telescopic arm that is currently operating; the arm position signal with the strongest signal is analyzed to obtain the target arm position information, and the target arm position information is sent to the display device.

[0086] Specifically, the second intelligent device 501 can also send the arm position signal with the strongest signal strength to the control device after obtaining the arm position signal with the strongest signal strength; the control device is used to analyze the arm position signal with the strongest signal strength, obtain the target arm position information, and send the target arm position information to the display device.

[0087] Specifically, the second intelligent device 501 of the present invention cannot receive multiple arm position signals at the same time, nor can it process multiple arm position signals at the same time.

[0088] Specifically, the signal strength determination strategy includes: when the number of arm position signals received at the current time is greater than a first preset number, randomly selecting a second preset number of active signal generating components from the arm position signals; sending a delay instruction to the selected second preset number of active signal generating components, the delay instruction including a delay duration, the delay instruction being used to instruct that the arm position signal be transmitted again after the delay duration; and simultaneously sending a sleep instruction to the first preset number of active signal generating components, the sleep instruction being used to instruct the active signal generating components to sleep, so that the active signal generating components will no longer transmit arm position information before being woken up.

[0089] The above process is iterated until all active signal generating components send an arm position signal once, which is received and processed by the second intelligent device 501.

[0090] Specifically, the number of "multiple" here is determined based on a first preset number. For example, if the second intelligent device 501 can only receive and process one arm position signal at the same time, then more than one arm position signal is considered multiple arm position signal. For example, if the second intelligent device 501 can only receive and process two arm position signals at the same time, then more than two arm position signals are considered multiple arm position signals.

[0091] The following explanation uses the example of a first preset number of 1, meaning that the second intelligent device 501 can only receive and process 1 arm position signal at a time:

[0092] For example, at the same time, four arm position signals are sent to the second intelligent device 501. The second intelligent device 501 receives the arm position signals, determines the number of signals, and if the number is four (4 is greater than one), it randomly selects three of the four active signal generating components to send delay commands. It then receives the arm position signal from the remaining active signal generating component, determines its signal strength, and sends a sleep command to that remaining active signal generating component. This process is iterated until the strengths of the four signals are determined. Finally, the arm position signal with the strongest signal strength is selected from the four signal strengths.

[0093] In one specific embodiment, the second intelligent device 501 includes an identification component and a communication component. The arm position detection system further includes a control device, which is wiredly connected to both the second intelligent device and the display device. The control device is further configured to send an enable signal to the communication component when it is determined that the active signal generating component is within the identification range of the identification component; the communication component is configured to receive the enable signal and activate the active signal generating component within its communication range.

[0094] The communication range is greater than the identification range.

[0095] Specifically, if the active signal generating component continuously generates an arm position signal, it consumes a large amount of power and has a short service life. Therefore, this invention puts the active signal generating component into sleep mode when it is determined that the active signal generating component is not within the recognition range of the second intelligent device 502, in order to save energy.

[0096] The communication component includes a low-frequency antenna.

[0097] Specifically, the identification component is used to receive arm position signals; determine the signal strength of each arm position signal; identify the telescopic arm corresponding to the active signal generating component of the arm position signal with the strongest signal strength as the telescopic arm that is in operation; and send the arm position signal with the strongest signal strength to the control device.

[0098] Specifically, the identification component receives arm position signals and executes the following signal strength determination strategy: if the number of arm position signals received at the current moment is greater than a first preset number, a delay command is sent to a second preset number of active signal generating components, and the signal strength of the arm position signals corresponding to the first preset number of active signal generating components is determined, as well as a sleep command is sent to the first preset number of active signal generating components, wherein the second preset number is less than the number of signals, and the first preset number is the difference between the number of signals and the second preset number; the signal strength determination strategy is repeated until the signal strength of each arm position signal is determined; the telescopic arm corresponding to the active signal generating component with the strongest signal strength is identified as the telescopic arm that is currently in operation; and the arm position signal with the strongest signal strength is sent to the control device.

[0099] Specifically, the identification component has a certain identification range. When the present invention determines that the finite signal generating component is within the identification range of the identification component, it activates or wakes up the active signal generating component within the communication range. By waking up the active signal generating component within the communication range, the accuracy of determining the operating telescopic arm is ensured.

[0100] In addition, the identification component and control device of the present invention communicate using high-frequency signals.

[0101] When the present invention determines that the finite signal generating component is within the recognition range of the recognition component, it activates the active signal generating component and transmits signals to it via 2.4Hz microwave. That is, the present invention uses low-frequency signals for precise positioning of the first intelligent device 201, and then uses high-frequency signals for rapid transmission to the display device. The recognition component transmits the acquired target arm position information back to the display device 103 via the CAN bus.

[0102] Of course, it can also be transmitted back to the display device 103 via wireless WiFi, 4G, 5G, Bluetooth, etc.

[0103] Correspondingly, the control device can send an enable signal to put the active signal generator into operation, and can also send a shutdown signal to put the active signal generator into sleep mode. It is evident that when the active signal generator is not activated, it is in sleep mode, i.e., in a low-power state, where power is only supplied to the portion of the active signal generator that stores data, thus extending the lifespan of the active signal generator.

[0104] In one specific embodiment, the second intelligent device 501 is further configured to adjust the arm position signal based on preset signal parameters after receiving the arm position signal, and determine the signal strength of the adjusted arm position signal.

[0105] Specifically, due to the instability of arm position signals, or the small difference in signal strength between two or more arm position signals, this invention uses preset signal parameters to increase the signal strength of the arm position signals based on the original arm position signals, so as to better distinguish the signal strengths with small differences and improve the accuracy of determining the arm position signal with the strongest signal strength.

[0106] In addition, the present invention can also reduce the transmission power of the active signal generator by using preset signal parameters, thereby reducing the number of arm position signals, reducing the amount of calculation, improving the calculation efficiency, and also extending the service life of the active signal generator component.

[0107] In one specific embodiment, the control device is also used to pre-bind the matching relationship between the second smart device 501 and each active signal generating component.

[0108] Specifically, each active signal generating component has a unique identifier. Through the matching relationship, the second intelligent device 501 ensures that it only processes active signal generating components that have a matching relationship with it, thus avoiding the intrusion of other active signal generating components.
