AGV real-time monitoring system

Abstract

The invention discloses an AGV real-time monitoring system. The system comprises an upper computer and an LORA gateway. Each AGV is provided with an LORA module. The LORA modules are in communicationconnection with the AGVs. The LORA modules and the AGVs form LORA terminals. Each LORA terminal and an LORA gateway form a star-shaped wireless network, and the LORA gateway is in network connection with an upper computer. The LORA module collects operation data of the AGV, the LORA module sends the operation data to the LORA gateway through a star-shaped wireless network, and meanwhile the LORA module can also receive the data transmitted by the LORA gateway. The LORA gateway is responsible for protocol conversion and data forwarding of LORA physical layer messages of all acquisition nodes, receiving uplink frame data of the LORA terminal module, analyzing and reporting the uplink frame data to the upper computer, receiving network downlink frame data from the upper computer, encoding andsending the network downlink frame data to the corresponding LORA terminal. The system can remotely monitor the running state of the AGV in real time, and is simple in structure, low in cost and suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of automatic guided transport vehicles, in particular to an AGV trolley real-time monitoring system. Background technique [0002] AGV (Automated Guided Vehicle) is an automatic guided transport vehicle, which is equipped with automatic guidance devices such as electromagnetic or optical, and is widely used in logistics and other industries. [0003] The working area of ​​AGV cars is large, and there are many AGV cars. In order to ensure that the AGV cars can carry out normal transportation work, it is often necessary to collect the data of the AGV cars during transportation and upload the data to the monitoring center for monitoring. However, the current traditional remote monitoring system functions Therefore, the remote monitoring data of AGV needs a data transmission network that can solve such problems.

Problems solved by technology

[0003] The working area of ​​AGV cars is large, and there are many AGV cars. In order to ensure that the AGV cars can carry out normal transportation work, it is often necessary to collect the data of the AGV cars during transportation and upload the data to the monitoring center for monitoring. However, the current traditional remote monitoring system functions The consumption is large and the scalability is weak. Therefore, the remote monitoring data of AGV needs a data transmission network that can solve such problems

[0004] The Chinese patent of "A LIFI communication device and AGV system for AGV system" (publication number CN 207612261 U), the device can realize the information exchange between the AGV car and the PC terminal of the host computer, and a local area network can also be formed between the AGV cars , but the cost of the device is high, and its function is complicated

The Chinese patent of "An Intelligent Express System Based on AGV Car Detection and UAV Communication Linkage" (public number CN 207851890 U), its system can realize data communication between AGV car and UAV, but the cost is too high, Highly affected by the environment
