[0014] The embodiments of the present application provide an intelligent control method and an intelligent control device for an AGV light strip, thereby solving the technical problem that the existing AGV light strip control method cannot adapt to AGV light strips of various types and specifications, resulting in poor control compatibility and flexibility, and difficulty in meeting the diverse needs of AGV indicator light control in different scenarios, thereby achieving the technical effect of improving the flexibility of AGV light strip control and scene adaptability.

[0015] Embodiment 1, as Figure 1 As shown, the embodiment of the present application provides an intelligent control method for an AGV light strip, the method comprising:

[0016] Step S1: Determine the target AGV in the interactive target scene, and extract AGV characteristic information according to the target AGV, wherein the AGV characteristic information includes control communication information and AGV light strip information.

[0017] Specifically, the target scenario refers to the working environment or task requirement scenario of the AGV. AGV characteristic information refers to the parameters and information required by the AGV during operation, including control communication information and AGV light strip information. The control communication information refers to the method and protocol for data exchange between the AGV and the control system; the AGV light strip information refers to the specific information of the indicator light strip installed on the AGV, such as the voltage requirement and working mode of the light strip.

[0018] Get the target scene where the AGV is located and determine the target AGV that needs to be operated. For example, in a large logistics warehouse scene, determine a specific AGV based on the task requirements of cargo handling. Then extract AGV characteristic information from this target AGV, including control communication information and AGV light strip information. By obtaining AGV characteristic information in a specific scene, basic data is provided for subsequent light strip control to improve the targeted control.

[0019] Step S2: According to the AGV light strip information, define the light strip driving voltage of the AGV control board, and establish a control connection between the AGV light strip and the AGV control board.

[0020] Specifically, the light strip driving voltage is the voltage value provided to the AGV light strip to make it work properly. Different types of light strips may require different driving voltages, for example, some light strips may require a driving voltage of 12V, while others may require 24V, etc. The AGV control board is the core hardware used to manage the various components of the AGV. Its functions include the control and voltage regulation of the light strip. The control connection refers to the electrical connection or communication connection between the control board and the light strip, ensuring that the control instructions can be passed from the control board to the light strip.

[0021] Define the light strip drive voltage of the AGV control board according to the AGV light strip information extracted in the previous step. For example, if the light strip information shows that a 12V voltage is required, the control board will be set to 12V output accordingly. Next, configure the control line between the AGV control board and the AGV light strip, and establish an electrical connection between the control board and the light strip. By defining the light strip drive voltage, the light strip can be guaranteed to work normally and stably, avoiding damage or abnormal operation of the light strip caused by voltage mismatch. Establishing a control connection provides a channel for subsequent control signal transmission, thereby improving the reliability of light strip control.

[0022] Step S3: According to the control communication information, define the control communication mode of the AGV light strip, and configure the communication connection between the AGV control board and the control signal source accordingly.

[0023] Specifically, the control communication method refers to the way of information exchange between the AGV light strip and the control signal source, such as wired communication, wireless communication, etc. Select a suitable communication protocol (such as RS232, RS485, CAN, TTL, etc.) according to the control communication information obtained in step S1, and configure the corresponding hardware interface according to the communication protocol to establish a communication connection between the AGV control board and the control signal source to ensure that the control signal can be smoothly transmitted from the signal source to the control board. By defining a suitable control communication method and configuring the communication connection, it can be ensured that the control signal can be accurately and efficiently transmitted between the control signal source and the AGV control board, which improves the reliability and flexibility of communication and adapts to the communication needs in different scenarios.

[0024] Step S4: the AGV control board receives the control instruction through the control connection, generates a corresponding control signal through the embedded instruction processor, and sends the control signal to the corresponding AGV light strip through the communication connection to perform intelligent control.

[0025] Specifically, the command processor is a processing unit embedded in the AGV control board, which is used to process the received control commands and generate corresponding control signals according to the command content. The control command is a command from the control signal source, which is used to guide the behavior of the AGV light strip. The control signal is a signal generated by the control board after processing the control command, which is used to control the working state of the AGV light strip, such as turning on, off, brightness adjustment, color switching, etc.

[0026] The AGV control board receives control instructions from the control signal source (such as a remote operation device) through the previously established control connection. For example, it receives an instruction to change the color and flashing frequency of the light strip. Then the embedded instruction processor inside the AGV control board processes this instruction and generates a corresponding control signal according to the specific requirements of the instruction. This control signal is sent to the corresponding AGV light strip through the previously configured communication connection, thereby realizing intelligent control of the AGV light strip.

[0027] By generating accurate control signals through the command processor and accurately sending them to the light strip through the communication connection, precise control of the AGV light strip can be achieved, the flexibility and accuracy of the AGV light strip control can be improved, and the AGV indicator light control requirements in different scenarios can be met.

[0028] Further, step S1 includes:

[0029] Step S11: determining the identity information of the target AGV, and matching the AGV specification data corresponding to the identity information in the AGV management database of the target scene.

[0030] Step S12: Based on the preset recognition prompt words, the AGV specification data is parsed in combination with the large language model to obtain the AGV light strip voltage information, light strip type information and light strip connection form information, and output as the AGV light strip information, wherein the light strip type information includes common cathode type and common anode type; the light strip connection form information includes light strip series connection and light strip parallel connection.

[0031] Specifically, the identification information is a set of information used to uniquely identify the AGV, which can be the AGV number, QR code, RFID tag, etc. The AGV management database is a database that stores the specifications and configuration information of all AGVs, and is used to manage and maintain the status and configuration of the AGV. The identification information of the target AGV is scanned or read through a visual recognition system, RFID reader or other sensor. After obtaining the identification information, the AGV specification data matching the identification information will be queried in the AGV management database. These data include the model, performance parameters and configuration information of the AGV.

[0032] The recognition prompt words are a set of keywords or phrases used to assist in parsing the AGV specification data, and are used to quickly locate and extract the required information. The large language model is a natural language processing technology that can understand and parse natural language text, and is used to extract specific information from the AGV specification data. The obtained AGV specification data is parsed using the preset recognition prompt words and the large language model. The prompt words can quickly locate the information related to the light strip in a large amount of text. After parsing this information, the information is integrated into the AGV light strip information and output for use in subsequent steps. For example, the AGV specification data contains a description: "This model AGV is equipped with a 24V common cathode light strip, and the connection method is parallel." These key information is extracted by recognizing the prompt words "24V", "common cathode" and "parallel", and output as AGV light strip information, that is: "The light strip voltage information is 24V, the light strip type information is common cathode, and the light strip connection form information is parallel." In this way, the subsequent light strip control and configuration can be performed based on this information.

[0033] Among them, the AGV light strip information includes the light strip voltage information, the light strip type information and the light strip connection form information. The light strip voltage information refers to the voltage level required for the light strip, and common voltage levels include 12V, 24V, etc. The light strip voltage information determines the value of the driving voltage. The light strip type information refers to the information that distinguishes whether the light strip is a common cathode type or a common anode type. A common cathode type light strip means that the cathodes (negative poles) of all lamp beads are grounded together, and the current controls the switch through the anode (positive pole) of each lamp bead. The control of the common cathode type light strip is relatively simple and suitable for lower current and voltage occasions. A common anode type light strip means that the anodes (positive poles) of all lamp beads are connected to the power supply together, and the current controls the switch through the cathode (negative pole) of each light strip. Common anode type light strips are usually used in scenarios that require higher voltage. The light strip connection form information refers to the physical connection method of the light strip, including series connection of the light strip and parallel connection of the light strip. Series connection means that all the lights in the light strip are connected end to end, the current flows through each light in turn, and the voltage is distributed to each light. Parallel connection means that all lights in the light strip are connected in parallel, and each light has an independent power connection.

[0034] By identifying and extracting the target AGV’s light strip information (including voltage type, type, and connection method), it ensures that the control board can provide the correct driving voltage for the light strip and selects the appropriate control strategy.

[0035] Further, step S3 includes:

[0036] Step S31: define the control instruction format according to the light strip control requirements of the target AGV.

[0037] Step S32: The interactive target scenario obtains historical operating condition data and performs operating condition clustering to obtain an operating condition interval set, wherein the operating condition interval set includes a primary operating condition interval, a secondary operating condition interval, and a tertiary operating condition interval.

[0038] Step S33: define the communication transmission mode under the operating condition interval set, and configure the corresponding control communication mode based on the communication transmission mode definition result.

[0039] Step S34: Associating the operating condition interval set, the communication transmission mode and the control communication mode, establishing a communication connection configuration table, and performing a communication connection between the AGV control panel and the control signal source according to the communication connection configuration table.

[0040] Among them, the control communication mode of the AGV light strip includes at least IO input control, RS232 communication control, RS485 communication control, CAN communication control and TTL communication control, and IO input control is the first priority control mode.

[0041] Specifically, the control instruction format refers to the structure and encoding rules of the control signal, which is used to ensure that the control signal can be correctly parsed and executed. The format of the control instruction is defined according to the light strip control requirements of the target AGV. This format will contain all the necessary information to ensure that the light strip can receive and execute the correct instructions. Exemplarily, the control instruction format can be [frame header][light strip number][instruction type][color information][brightness information][verification], where the frame header is used to identify the start of the instruction; the light strip number clearly indicates which light strip is to be operated; the instruction type indicates the type of operation to be performed, such as color change, brightness adjustment, etc.; the color information and brightness information specify the visual effect to be achieved by the light strip, and the verification part is used to check the accuracy of the instruction.

[0042] Historical operating data refers to the working status and environmental data collected by the AGV during its past operation. The operating interval set is a series of intervals defined according to different working conditions and requirements, which are used to guide communication and control strategies. Interact with the target scene, collect the historical operating data of the AGV, and then use data analysis technology to perform clustering to identify different working modes. These working modes are defined as different operating intervals, including primary, secondary and tertiary operating intervals, each of which corresponds to different working conditions and control requirements. In the operating interval, the control requirements decrease step by step in the order of primary, secondary and tertiary.

[0043] The communication transmission mode refers to the communication strategy used under specific working conditions, including the rate, reliability and real-time requirements of data transmission. Based on the defined working condition interval set, define the appropriate communication transmission mode for each interval. These modes will consider the efficiency and reliability of data transmission to meet the control requirements under different working conditions. For example, in the light load and low speed interval, a lower data transmission rate is selected to save energy; while in the heavy load and high speed interval, a high data transmission rate is required to ensure real-time control.

[0044] The communication connection configuration table is a table containing the correspondence between the working condition interval, communication transmission mode and control communication method, which is used to guide the setting of communication connection. Associate the working condition interval set, communication transmission mode and control communication method to establish a communication connection configuration table. This table will guide the AGV light strip control system on how to select the appropriate communication method according to the current working conditions and configure the communication connection between the AGV control board and the control signal source.

[0045] The control communication mode refers to the different ways of data exchange between the AGV control board and the control signal source, which determines how to transmit control instructions and receive feedback information, including but not limited to IO input control, RS232 communication control, RS485 communication control, CAN communication control and TTL communication control. IO input control is a way to directly control the light strip through the input / output interface. Because of its simple implementation and fast response speed, the highest priority is set for IO input control. When selecting the control communication mode, IO input control is preferred. Only when the current working scene or AGV does not support IO input control, other control communication modes will be selected. RS232 communication control is a serial communication protocol that realizes data transmission between devices through the serial port. It is suitable for short-distance communication and is usually used for simple serial communication between devices. RS485 communication control is a differential serial communication protocol that is suitable for long-distance transmission and supports multi-point communication. Compared with RS232, RS485 has stronger anti-interference ability and is suitable for use in industrial environments. CAN communication control is a communication protocol designed specifically for complex systems and is suitable for multi-node systems. In AGV control, CAN communication is often used in control scenarios that require high speed and high reliability, especially in complex industrial automation and robotics systems. TTL communication control is a low-level voltage serial communication method that is suitable for scenarios that require high communication speed and short transmission distance.

[0046] Further, step S33 includes:

[0047] Step S331: define the communication transmission mode of the first-level operating condition interval as full-duplex, and correspondingly configure the control communication mode supporting full-duplex for synchronous execution of instruction transmission and feedback transmission.

[0048] Step S332: define the communication transmission mode of the secondary operating condition interval as half-duplex, and correspondingly configure the control communication mode supporting half-duplex for alternately executing command transmission and feedback transmission.

[0049] Step S333: define the communication transmission mode of the third-level operating condition interval as simplex, and correspondingly configure the control communication mode supporting simplex for executing feedback-free instruction transmission.

[0050] Specifically, the communication transmission mode of the first-level working condition interval is defined as full-duplex. The full-duplex mode allows simultaneous command transmission and feedback transmission, that is, data can be received while sending data. And configure the corresponding full-duplex control communication mode. Such as RS485 communication control or CAN communication control. Through the full-duplex control communication mode, two-way communication between the AGV control board and the control signal source can be achieved in the first-level working condition interval, which has high control requirements. For example, in a complex automated production scenario, the task execution of the AGV is very compact and requires a fast response. When the control signal source issues a command to the AGV light strip to change the color and brightness, it can also receive feedback from the AGV light strip about the current state (such as whether the command is successfully received, the current actual brightness and color, etc.). In this way, the control strategy can be adjusted in time to ensure that the control effect of the light strip reaches the best state, thereby meeting the production requirements of high precision and high real-time performance.

[0051] Define a half-duplex communication transmission mode for the secondary working condition interval. In this working condition, the AGV control board needs to send instructions and receive feedback alternately, and cannot do so at the same time. At the same time, configure a control communication method that supports half-duplex for the secondary working condition interval to meet the data transmission requirements of this working condition. For example, RS485 communication control or RS232 communication control.

[0052] A simplex communication transmission mode is defined for the three-level working condition interval. In this working condition, the AGV control board only sends instructions and does not receive feedback. At the same time, a control communication method that supports simplex (such as IO input control) is configured for the three-level working condition interval to simplify the communication process.

[0053] Further, such as Figure 2 As shown, step S2 includes:

[0054] Step S21: extracting the light strip voltage information based on the AGV light strip information.

[0055] Step S22: If the light strip voltage information is within the adjustable range of the AGV control board driving voltage, the driving voltage of the AGV control board is defined by the light strip voltage information.

[0056] Step S23: based on the AGV light strip information, extract the light strip type information and the light strip connection form information, and configure the light strip type information as a first call constraint, and configure the light strip connection form information as a second call constraint.

[0057] Step S24: According to the first call constraint and the second call constraint, traverse the preset control connection solution library, match the corresponding control connection solution, and perform control connection between the AGV light strip and the AGV control board according to the matching result.

[0058] Specifically, the adjustable range of the AGV control board driving voltage refers to the voltage range that the AGV control board can adjust. The control board can adjust the output voltage according to this range to match light strips with different voltage requirements. The adjustable range of the AGV control board driving voltage determines the type of light strips that the control board can adapt to.

[0059] The light strip voltage information is obtained through the AGV light strip information extracted in step S1. Check whether the extracted light strip voltage information is within the adjustable voltage range of the AGV control board. If so, the output voltage of the control board is set to the light strip voltage information.

[0060] Extract the light strip type information (such as common cathode or common anode) and the light strip connection form information (such as series or parallel connection) from the AGV light strip information, and set the light strip type information as the first call constraint, and the light strip connection form information as the second call constraint. These two call constraints restrict the control scheme to ensure that the control connection scheme can meet the specific requirements of the light strip.

[0061] According to the first and second call constraints configured in step S23, the preset control connection scheme library is traversed to find the control connection scheme that best suits the current AGV light strip. The control connection scheme library stores a variety of preset control connection schemes, including information such as control methods, driving voltages, circuit connection methods, etc. for light strips of different types and connection forms. Once a matching scheme is found, the connection configuration between the AGV light strip and the control board is performed according to the scheme, such as connecting the corresponding lines or configuring related circuit parameters to ensure that the light strip can correctly receive the control signal. By setting call constraints and matching the control connection scheme according to the constraints, it can be ensured that the control connection method that best suits the current light strip type and connection form is found, thereby improving the accuracy and efficiency of the control connection.

[0062] Further, step S34 includes:

[0063] S341: Based on the association between the first-level operating condition interval, the second-level operating condition interval, the third-level operating condition interval and the communication transmission mode, and the control communication method in the operating condition interval set, construct the communication connection configuration table, wherein each row in the communication connection configuration table corresponds to an operating condition interval, and each column corresponds to a communication transmission mode, the control communication method and a specific configuration identifier.

[0064] S342: According to the AGV role information of the target AGV, multiple working condition matching is performed in the working condition interval set to obtain a target working condition set.

[0065] S343: Perform traversal matching in the communication connection configuration table based on the target operating condition set, simplify the matching results with the minimum control communication mode as the target, and output as a target connection solution.

[0066] S344: Establishing a communication connection between the AGV control board and the control signal source according to the target connection scheme.

[0067] Specifically, the relationship between different operating ranges, communication transmission modes and control communication methods is sorted and recorded to construct a communication connection configuration table. Each row in the communication connection configuration table corresponds to an operating range, and each column corresponds to a communication transmission mode, a control communication method and a specific configuration identifier. This table will serve as the basis for subsequent matching and configuration of communication connections.

[0068] AGV role information is information that identifies the role or task type of the AGV in operation. According to the AGV role information of the target AGV, a match is performed in the working condition interval set to determine multiple working condition intervals applicable to the AGV, forming a target working condition set, so as to identify different communication configurations required by the AGV under different working conditions.

[0069] The target connection scheme is the optimal communication connection scheme obtained by matching the target working condition set and the communication connection configuration table. Based on the target working condition set, the communication connection configuration table is traversed and matched to determine the most suitable communication connection scheme under each working condition. All the matched communication connection schemes are screened to simplify the matching results with the goal of controlling the minimum communication mode, that is, the communication connection scheme that meets as many working conditions as possible is selected and determined as the final target connection scheme to reduce the complexity of the system and the communication cost.

[0070] Establish a communication connection between the AGV control board and the control signal source according to the target connection scheme, including selecting appropriate cables and interfaces for hardware connection according to the control communication method specified in the target connection scheme, and then configuring the corresponding communication parameters in the software, such as baud rate, data bit, stop bit, etc. By establishing a communication connection, the control signal can be accurately transmitted from the control signal source to the AGV control board, thereby realizing the control of the AGV light strip.

[0071] Furthermore, the method further comprises:

[0072] S345: Monitor the task list of the target AGV in real time, and determine the forward-looking working condition interval corresponding to the task at the next moment in the task list according to the working condition interval set.

[0073] S346: If the level of the forward-looking operating condition interval is lower than the level of the operating condition interval corresponding to the current communication connection, the communication transmission mode is downgraded when the task is executed at the next moment.

[0074] S347: If the forward-looking operating condition interval is higher than the level of the operating condition interval corresponding to the current communication connection, the communication transmission mode is upgraded before the next task is executed.

[0075] Specifically, the task list of the target AGV is monitored in real time. The task list contains the task sequence that the target AGV needs to perform, including information such as the type, sequence, and time of the task. According to the specific content and time schedule of the task, the task that the AGV will perform at the next moment is predicted, and the forward-looking working condition interval corresponding to the task is determined according to the working condition interval set, so that the communication configuration can be prepared and adjusted in advance to adapt to the upcoming task requirements.

[0076] Compare the level of the forward-looking working condition interval corresponding to the task at the next moment with the level of the working condition interval corresponding to the current communication connection. If the level of the forward-looking working condition interval is lower than the working condition interval corresponding to the current communication connection, the communication transmission mode will be automatically reduced when the task is executed at the next moment to reduce resource consumption and maintain communication efficiency. For example, if the current communication connection is configured as full-duplex mode, which is suitable for the first-level working condition interval, and the forward-looking working condition interval is the second level, the communication mode will be downgraded to half-duplex when the task is executed, and the control communication mode corresponding to half-duplex will be switched to meet the needs of the second-level working condition interval.

[0077] If the level of the forward-looking working condition interval is higher than the working condition interval corresponding to the current communication connection, the communication transmission mode will be automatically improved before the next task is executed to ensure the reliability and real-time performance of the communication, and to ensure that the AGV can stably and reliably receive and send data in high-demand tasks. For example, if the current communication connection is configured as half-duplex mode, which is suitable for the second-level working condition interval, and the forward-looking working condition interval is the first level, the communication mode will be upgraded to full-duplex during task execution, and the control communication mode corresponding to full-duplex will be switched to meet the high requirements of the first-level working condition interval.

[0078] In summary, the intelligent control method of an AGV light strip provided in the embodiment of the present application has the following technical effects:

[0079] By interactive target scenarios, the target AGV is determined and AGV characteristic information is extracted to obtain the personalized features of the AGV, ensuring that the subsequent light strip control can be optimized for the specific needs of each AGV. The light strip driving voltage is defined according to the AGV light strip information, and the control connection between the AGV light strip and the AGV control board is established to ensure that the power supply of the control system matches the working requirements of the light strip, avoiding control failure or light strip failure caused by voltage mismatch. The communication mode of the light strip is defined according to the control communication information and the connection between the AGV light strip and the control signal source is established to ensure that the control command can be transmitted from the AGV control board to the light strip. In this way, different types of AGVs can use different communication methods, which enhances the compatibility and flexibility of the control system. The control instructions are received and the corresponding control signals are generated through the command processor embedded in the control board, and the signals are sent to the AGV light strip for execution through the preset communication connection, realizing intelligent automatic control and improving the real-time and accuracy of the control.
