Description

Technical Field

[0001] The present invention relates to the technical field of material inventory counting, and in particular to an RFID-based photovoltaic station inventory counting robot. Background Art

[0002] The inventory of materials in traditional photovoltaic sites not only uses methods such as EXCEL ledgers, QR codes, bar codes, fixed asset cards, etc., but also uses the following methods:

[0003] 1. On-site inventory method

[0004] This method is to conduct a comprehensive inspection and assessment of the photovoltaic site, including the operating status, fault conditions, damage conditions, etc. of photovoltaic equipment such as photovoltaic modules and inverters.

[0005] On-site inventory helps to directly observe the actual condition of the equipment, but it may consume more manpower and time.

[0006] 2. Data Inventory Method

[0007] Data inventory refers to analyzing and comparing relevant data of photovoltaic sites, including the operating status of inverters and box transformers, power output, energy output and other data, to understand the actual situation of photovoltaic sites.

[0008] Through data analysis and comparison, the operating status and performance of the equipment can be more accurately understood, but it depends on an accurate data recording and analysis system.

[0009] 3. Drone inspection technology

[0010] With the development of drone technology, drones have been widely used in photovoltaic station inspections. Drones can easily and quickly perform various inspection tasks such as aerial inspections of photovoltaic panels, transmission towers, and booster station equipment. Drone inspections can provide clear and reliable video and photo data for subsequent data processing and fault analysis.

[0011] The drone inspection method requires accurate control of the drone's trajectory. The control process is relatively complicated and the cost of the drone is relatively high.

[0012] 4. Fixed assets inventory system

[0013] Some photovoltaic stations use fixed asset inventory systems based on different types of power stations, such as generating a virtual photovoltaic power station fixed asset library in a templated manner. Inventory personnel can use drones, mobile devices, and GPS information to conduct fixed asset inventory according to the virtual photovoltaic power station fixed asset library. This system is based on equipment information and generates interrelated codes in accordance with standard coding methods, which improves the efficiency and accuracy of inventory.

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Some embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] With the rapid development of the photovoltaic industry, the inventory and management of materials such as photovoltaic components and booster station equipment in photovoltaic stations have become particularly important. In order to improve the efficiency of inventory and reduce manual intervention, the present invention provides a robot based on RFID (Radio Frequency Identification) technology, which can realize unmanned automatic inventory of materials such as photovoltaic components and booster station equipment. The present invention uses RFID technology to read the material information on the label to realize fast and accurate unmanned automatic inventory.

[0042] See also Figure 1 The present invention provides a photovoltaic station inventory robot based on RFID, including an RFID reader / writer, a navigation unit, a positioning unit and a control unit, wherein the RFID reader / writer, the navigation unit and the positioning unit are all electrically connected to the control unit.

[0043] Among them, the RFID reader is used to identify the tags set on the materials to be counted, so as to read the corresponding material information on the tags. The tags can be attached to the photovoltaic modules and booster station equipment of the photovoltaic station waiting for inventory, and in order to facilitate reading by the RFID reader, the tags are set on the surface of the materials to be counted as much as possible and are not blocked by the materials to be counted. In order to improve the speed and accuracy of reading, the tags can be ultra-high frequency (UHF) RFID tags.

[0044] The navigation unit is used to plan the inventory route based on the layout of the photovoltaic station and the distribution of the materials to be counted through the built-in navigation algorithm. The planning of the inventory route needs to ensure that the robot can cover all the materials to be counted and try to avoid conflicts with personnel, equipment, etc.

[0045] The positioning unit is used to calibrate the initial position of the robot after it is started.

[0046] The control unit is used to control the robot to walk according to the inventory path.

[0047] Furthermore, the navigation unit includes obstacle avoidance equipment such as laser radar and infrared sensor. The navigation unit is also used to optimize the inventory path in real time during the robot's walking process based on the environmental information sensed by the laser radar and infrared sensor combined with the built-in navigation algorithm, thereby ensuring the safe driving of the robot. The control unit is also used to control the robot to walk according to the real-time optimized inventory path.

[0048] The positioning unit can be a BeiDou Navigation Satellite System (BDS). Compared with the traditional RFID technology, the present invention adds a positioning unit, which can realize the dual verification of spatial location information and material information, and improve the accuracy of inventory. RFID technology combined with BeiDou positioning enables the robot to locate and read material information more accurately.

[0049] In some embodiments, Figure 2 As shown, the robot includes a base 10 and a lifting rod 20 disposed on the base 10, an RFID reader 30 is fixedly disposed at the end of the lifting rod 20, and a control unit (not shown) is also used to control the lifting of the lifting rod 20, thereby adjusting the height of the RFID reader 30 to adapt to materials to be counted at different heights (not shown). Ensure that the RFID reader is within a suitable distance range from the label on the material to be counted, thereby ensuring that the robot can read the corresponding material information on the label through the RFID reader.

[0050] Therefore, the robot's inventory operation process can be:

[0051] The robot starts and calibrates its own position through the Beidou satellite navigation system.

[0052] The vehicle moves according to the initial inventory path or the real-time optimized inventory path. During the movement, obstacle avoidance equipment such as lidar and infrared sensors are combined with the navigation algorithm built into the navigation unit to ensure safe driving.

[0053] Walk to the materials to be counted, the control unit controls the lifting rod to adjust to the appropriate height, the RFID reader starts working, quickly scans the labels on the materials to be counted, and reads the material information on the labels.

[0054] After reading is completed, the robot continues to walk along the inventory path to the next material to be counted until all materials are counted.

[0055] Specifically, the robot also includes a transmission unit; the transmission unit is electrically connected to the RFID reader, and the transmission unit is used to wirelessly transmit the material information read by the RFID reader to the background management system, so that the background management system can process and analyze it. The background management system stores the material information counted by the robot in the database and generates corresponding reports and statistical data, which can be used for decision support in material management, inventory monitoring, production planning, etc.

[0056] In some embodiments, the control unit has a built-in AI (Artificial Intelligence) decision tree algorithm, which is used to control the robot to perform corresponding operations according to the preset emergency handling method when the robot encounters an abnormal situation, so as to have an emergency handling mechanism for sudden abnormal situations. For example, when the robot is low on power, the robot is controlled to return to the charging station; when the robot encounters an obstacle, the navigation unit is controlled to optimize the current inventory path, and the robot is controlled to walk along the optimized inventory path to continue to complete the inventory of materials. Furthermore, the control unit is also used to evaluate the risk factors in the environmental information in real time and automatically take the best response measures; and to intelligently classify and predict the material information read by the RFID reader, discover potential problems in advance, and achieve preventive maintenance. The control unit is provided with a voice interaction module, and control instructions are input through the voice interaction module to control the robot to perform corresponding operations, which can realize voice interaction and command control and improve the convenience of operation.

[0057] Specifically, the robot also includes a display unit; the display unit is electrically connected to the control unit, and the display unit is used to display the material information read by the RFID reader, and display an alarm prompt message when the robot encounters an abnormal situation.

[0058] The present invention realizes unmanned and intelligent inventory and management of key areas such as photovoltaic modules and booster station equipment in photovoltaic stations by refining the inventory operation process, improving the emergency response mechanism, and strengthening data processing and AI algorithm application. The present invention not only significantly improves the efficiency and accuracy of inventory, but also reduces labor costs and safety risks, and has significant innovation and practical value.
