[0032] The control module 3 is connected to the alarm module 4 for sending an alarm signal to the alarm module 4 after receiving the control signal sent by the forklift detection system 2;
[0033] The alarm module 4 is arranged around the workshop intersection and is used for giving an alarm after receiving the alarm signal sent by the control module 3 .
[0034] like Figure 3 As shown, in this embodiment, the forklift detection system 2 includes a license plate recognition unit, a storage unit and a comparison unit;
[0035] More specifically, the input end of the license plate recognition unit is communicatively connected to the output end of the monitoring module 1; the output end of the license plate recognition unit and the output end of the storage unit are electrically connected to the input end of the comparison unit respectively, and the output end of the comparison unit is electrically connected to the control module 3.
