With the continuous implementation of Industry 4.0, the logistics industry has also moved towards intelligence. Unmanned handling and intelligent sorting have been applied to the transportation industry. The emergence of AGV smart cars has greatly improved the efficiency of various tasks and also saved In consideration of labor costs, AGV handling robots are bound to play an important role in various fields.
Tangxiang Intelligent Research Institute has developed the industrial touch display screen of the AGV vehicle monitoring system. The system can realize the factory-level and workshop-level AGV system vehicle management, traffic management, dispatch management, operation management, task management, communication management, and automatic charging functions. . The system can be connected with the MES system, WMS system, production line system, etc., through the AGV trolley to understand the entire production process and analyze the data automatically generated by the AGV trolley backstage, and continuously optimize the production process to create a flexible and modern intelligent logistics system.
The AGV system is mainly composed of AGV trolley, ground navigation and positioning system, charging system, WG581 industrial intelligent gateway wireless communication, and vehicle-mounted industrial tablet computer. Among them, the industrial intelligent gateway has its own WIFI function and is installed in the AGV car body through the workshop. Wireless APs in different areas (or through 3G/4G networks) establish wireless connections, complete security features to ensure that the system is protected from intrusion, support a wide operating temperature, meet a variety of harsh outdoor environment applications, and ensure the AGV monitoring center cloud platform and on-site sports Reliable communication of AGV vehicles in China.
System functions:
The AGV is controlled by PLC, and the car has an industrial intelligent gateway, which can communicate wirelessly with the AGV cloud platform and execute the instructions of the AGV cloud platform. The AGV cloud platform can monitor the operating status of all AGV trolleys in the system according to the position and status signals reported by the AGV trolley, complete the alarm operation when an abnormality occurs, and is also responsible for collecting the transportation requirements of each station in the transportation system, and according to the signal of each transportation station The state automatically assigns the tasks of the AGV trolley, and the PLC makes the AGV trolley read the ground identification through RFID according to the read data, and make corresponding actions (change speed, steering, positioning and parking, etc.), so as to realize the function of the AGV dispatching system and the station GPS.
AGV system advantages:
①Safety-The path of a human-driven vehicle cannot be ascertained, but the guidance path of the AGV is very clear, which improves safety.
②Cost control-The capital investment of the AGV system is short-term, while the employee's salary is long-term, which will continue to increase with inflation. The battery charging and management are automatically completed by the AGV system, which can prolong battery life and reliability, and can also reduce cargo damage caused by manual and rude operations.
③Flexible and predictable dispatching ability-AGV will automatically stop when encountering obstacles on the driving path or allow to change the path planning to the greatest extent, but it is not necessary for human-driven vehicles.
④Edge computing to realize predictive operation and maintenance-Wutong AGV system has edge computing capabilities. Through the local deployment of applications, it realizes real-time data processing, local pre-analysis, and real-time fault warning. At the same time, predictive operation and maintenance can be realized through the collaboration of edge computing and cloud big data analysis.
⑤Open architecture, innovation and value-added-The industrial intelligent gateway in the AGV system of Wutong Company integrates computing, storage, analysis, data and other functions. It can be connected to cameras, other peripherals, etc., and is open to third parties through the industrial intelligent gateway Software developers to facilitate AGV manufacturers to develop unique value-added functions.
⑥ IOT data application platform-Wutong's application cloud system can perform data management and big data analysis. According to the characteristics of AGV industry equipment and applications, data mining, intelligent analysis and display of industry curves, reports, map locations, etc. can be performed.
