In addition, the steel product management software can display the warehouse map and display the information of the steel product operation task, so that the forklift driver can grasp the real-time steel product operation dynamic. An example of the display interface of the steel management software is shown in Figure 2. In one embodiment, for example, when steel products are taken out from a truck, when the stacker is loaded with steel products 105, the photoelectric sensor 130 detects the steel products and determines that the steel products have been stored according to the time that the steel products stay in the stacker. Loaded stably (that is, the steel product stays stably in the position where the stacker is raised and the photoelectric sensor can continuously sense the range of the steel product). When the information collected by the steel management software from the photoelectric sensor 130 can confirm that the steel is stably loaded, the signal read by the electronic tag reader 140 from the first antenna 122 will be collected to determine the loaded steel. identity and quantity. In another embodiment, the steel products are unloaded from the stacker to the storage area. When the stacker arrives at the steel product storage area, such as the storage area 160, the electronic tag reader 140 can read the corresponding storage area 160.

At this time, if the photoelectric sensor 130 detects that the steel product is unloaded, the electronic tag reader 140 will also read the information from the photoelectric sensor 130 and transmit it to the steel product management software. Finally, the steel product management software determines the identity, quantity and location of the steel products that have been placed in the steel product storage area 160 according to the position signal and unloading information received by the electronic tag reader, and displays the relevant information. It should be noted that the steel management software has already obtained the identity and quantity of the steel when the steel is loaded. Therefore, when unloading the steel products to the storage area, the identity, quantity and position of the stored steel products can be determined only according to the unloading information of the photoelectric sensor 130 and the position signal of the second antenna.

Please refer to Figure 3 and match Figure 1 at the same time. Fig. 3 is a flowchart of the steel product management method of the present invention. First, step S1 is performed: a plurality of electronic tags of steel products are respectively arranged on the steel products 105 . In one embodiment, the steel products 105 are all provided with electronic tags, such as RFID. Next, step S2 is performed: a plurality of position electronic tags are correspondingly arranged in the steel product storage areas 160 , 170 and 180 . The ground of each steel product storage area is provided with at least one location electronic tag 110, such as a buried RFID.

Next, step S3 is performed: a plurality of antennas 120 are arranged on the stacker to receive the signals of the steel product electronic tag and the position electronic tag 110 .

For the task of receiving steel products, referring to the display interface of FIG. 2 , the driver can see from the mobile device 150 that the steel product management system indicates how many steel products are expected to be transported, and provides the area where these steel products will be stored Location. For example, when steel products are taken out from a truck, when the stacker is loaded with steel products, the photo sensor 130 will detect the steel products 105 and determine that the steel products 105 have been stably loaded according to the time that the steel products 105 stay in the stacker. When the information collected by the steel management software from the photoelectric sensor 130 can confirm that the steel is stably loaded, the signal read by the electronic tag reader 140 from the antenna 120 will be collected to determine the identity of the loaded steel 105 and quantity. In addition, the steel product management software will provide the steel product storage area, so that the forklift driver can know which steel product storage area 160, 170, 180 to go to. When the stacker comes to the designated area, the antenna 120 on the stacker will receive the signal of the position electronic tag 110 . At this time, if the photoelectric sensor 130 detects that the steel product is unloaded, the steel product management software will receive the unloading information from the electronic tag reader 140 . Finally, the steel product management software can determine the identity, quantity and location of the steel products unloaded to the steel product storage area according to the signals and information received by the electronic tag reader 140, and display the relevant information. In this embodiment, the steel product management software will further transmit the information to the above-mentioned upper-level system, indicating the completion of the procedures of logistics and information flow.
