[0002] The IGV automated unmanned vehicle in the automated horizontal transportation system has been running in a closed unmanned area for a long time. After a single-machine positioning and navigation failure occurs, the staff currently goes to the site to use the remote control equipment based on wireless communication 4G technology to straighten the IGV automated unmanned vehicle or drive it out of the work area for fault handling. The existing positioning fault troubleshooting process is as follows: Fault starts->Technical department notifies the business department of the troubleshooting site requirements->Business department sets up the relevant paths and task closed areas->Technical department corrects the location of the on-site equipment or manually tows it away from the business lane->Technical department on-site personnel evacuates the site->Business department restores relevant tasks and regional closed tests->Fault removal takes about 30-40 minutes. The fault handling process is relatively complicated, and there are many cooperating business departments, involving technical department personnel entering the site, which increases the risk of personnel entering the site, resulting in a large range of automated areas unable to operate automatically. In addition, the remote control equipment used for positioning fault troubleshooting is based on wireless communication 4G technology, which can only be used to transmit the automated vehicle's phased operation instructions and equipment operation. The latency and uplink bandwidth of wireless communication 4G technology cannot meet the remote real-time control of remote fault handling of IGV automated vehicles. Summary of the invention
