At present, vehicle information recognition is mainly done by manual methods or video recognition methods. Relying on humans is prone to information errors and delays, resulting in inefficiency and data disorder. Although video recognition technology is easy to automate information, it requires frequent wiring in the field. Undoubtedly, these two methods are not ideal management tools for engineering fleets contracting short- and medium-term projects. With the help of RFID handheld, vehicle counting and labor cost settlement can be carried out for this project, which is convenient and reliable, and it is once and for all. At present, this solution has been successfully applied in an engineering fleet.
