[0046] Embodiment 2:

[0048] The present invention adopts radio frequency identification technology to carry out cold-rolled coil information identification and automatic identification. The cold-rolled coil radio frequency automatic identification device includes a composite label for cold-rolled coil identification, an automatic identification host and an automatic identification auxiliary machine. The automatic identification host is composed of a control machine, a UHF RFID reader / writer, an antenna array, a power supply component, a network device, an audible and visual warning device, a movable bracket and a protective cover auxiliary; the automatic identification auxiliary machine is composed of a UHF RFID reader / writer, an antenna array, a movable bracket and a protective cover. During installation, the main and auxiliary machines are installed on both sides of the transport lane.

[0049] The UHF RFID reader / writer uses a high-sensitivity, high-power, high-performance device. It can realize long-distance tag reading in conjunction with the antenna, while maintaining a reading frequency of 5 times / s. When the system is running on site, it can achieve reliable reading of RFID tags on up to 35 cold-rolled coils at a time. The RFID antenna adopts a high-gain, omnidirectional and directional composite layout to have enough energy to stimulate the normal operation of the tag and receive the feedback signal of the tag.

[0050] When the system is working, the radio frequency composite tag containing the cold-rolled coil information is attached to the cold-rolled coil. When the vehicle carrying the cold-rolled coil passes through the reading area of ​​the system, the system control module controls the reader-writer in the automatic identification host and auxiliary machine to transmit the radio frequency identification signal in turn, and the signal is transmitted to the working space of the lane through the antenna. After receiving the radio frequency signal from the reader-writer, the radio frequency composite tag will transmit the tag signal to the receiving antenna of the main and auxiliary machines. The reader-writer in the main and auxiliary machines receives the radio frequency tag information from the antenna and converts it into digital information and transmits it to the control machine in the host through the network device. The control machine is connected to the background system through the network to realize information interaction. During operation, the control unit in the host controls the radio frequency main and auxiliary machines to work in turn; at the same time, the network connection and power supply are carried out through the host.

[0051] A method for automatically identifying cold rolled coil identification information based on radio frequency identification technology, the reading process of which is radio frequency tag generation, automatic tag reading and identification of steel coil number output (see Figure 1 ), the cold-rolled coil information identification and automatic identification method based on radio frequency identification technology comprises the following steps:

[0052] Step 1: The cold-rolled coil label generation module generates information labels for cold-rolled coil identification. The cold-rolled coil identification information is obtained from the manufacturing system, including: factory type, coil number, specification, and weight. And it is converted into ASCII code, hexadecimal code, and binary code according to the encoding rules. After the encoding is completed, the label generation module outputs the encoding information and identification data to the interface of the radio frequency generation device, and the radio frequency generation device writes the label electronic information and generates and outputs the label visual information. The radio frequency identification composite label is a PP paper label with a radio frequency identification chip. The label adopts an anti-metal design and is installed in the radio frequency label generation device. After the label is generated, it is pasted on the core of the cold-rolled coil.

[0053] Step 2: The cold-rolled coil radio frequency automatic identification device includes an automatic identification host and an automatic identification auxiliary machine. The automatic identification host consists of a control machine, a UHF RFID reader / writer, an antenna array, a power supply component, a network device, a movable bracket and a protective cover; the automatic identification auxiliary machine consists of a UHF RFID reader / writer, an antenna array, a movable bracket and a protective cover. When working, the host control unit controls the radio frequency main and auxiliary machines to work in turn; at the same time, the network connection and power supply are carried out through the host (see Figure 2 ).

[0054] Step 3: When reading, the main machine and auxiliary machine are automatically identified and placed on both sides of the cold rolled coil transport vehicle channel (see Figure 3 ). When a vehicle carrying cold-rolled coils passes by, the system control module first controls the automatic identification host to transmit the RFID signal and receive the tag information fed back by the RFID tag; then starts the automatic identification auxiliary machine to transmit the RFID signal and receive the tag information fed back by the RFID tag (see Figure 4 ). The system works for 2 seconds each time; a total of 5 cycles of scanning and reading are performed.

[0055] Step 4: After the automatic identification host receives the cold-rolled coil label information, the system analysis module analyzes the received label information, and the system output module outputs the analysis result to the application interface.

[0056] Preferably, when the total number of label information, the label information and the planned number of cold-rolled coils in and out and the cold-rolled coil information received by the system are consistent, the correct reading information is output to the system status interface.

[0057] Preferably, when the total number of label information, the label information and the planned number of cold-rolled coils in and out and the cold-rolled coil information received by the system are inconsistent, the reading abnormality information is output to the system status interface.

[0058] The present invention can effectively improve the efficiency of cold-rolled steel coils entering and exiting warehouses, yards and other places, and reduce the intensity and error rate of manual work. The present invention realizes the visualization and electronicization of cold-rolled coil information by adopting radio frequency composite electronic tags; compared with traditional paper labels, the identification information is more reliable and less prone to contamination. The present invention realizes automatic reading of cold-rolled coil information through a radio frequency reading device; it is free from traditional manual operation and improves efficiency. The present invention improves the abnormal warning device, solves the problem that it is difficult for on-site personnel to detect abnormal cold-rolled coil numbers, and makes the system more intelligent.
