[0002] Torpedo tank cars, also known as torpedo-type mixing iron cars, are large-scale molten iron transportation equipment with advantages such as low heat loss, long heat preservation time, and energy conservation. They can also store molten iron to coordinate the temporary imbalance between ironmaking and steelmaking. At the same time, they can replace steelmaking mixing iron furnaces and ordinary molten iron tank cars, and can also complete desulfurization and dephosphorization operations during the molten iron transportation process.

[0003] After loading the molten iron, the torpedo tanker needs to be registered and then covered and opened before driving out.

[0043] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0044] An industrial wireless control method for adding and removing covers on torpedo tank cars, such as Figure 1 As shown, the method includes the following steps:

[0045] Step 1: The RFID reader reads the tag on the side of the torpedo tanker that enters the detection area to obtain the torpedo tanker and the cover information that needs to be added;

[0046] Specifically, a tag is first fixed to the surface of each torpedo tank car. The tag is used to mark the torpedo tank car number, size, amount of molten iron inside the torpedo tank car, transportation location, and the size of the cover to be added. A corresponding receiver is pre-installed for each torpedo tank car with a different number. When the torpedo tank car enters the detection area, the radio frequency identification reader reads and identifies the tag on the side of the torpedo tank car to obtain the information on the tag.

[0047] Step 2: The transmitter receives the information read and written by the RFID reader, and at the same time changes the channel of the transmitter to make it consistent with the pre-configured receiver channel;

[0048] Specifically, the transmitter is connected to the RFID reader / writer via a 485 wired interface. The transmitter reads the information read by the RFID reader / writer to obtain the torpedo tanker information and the cover opening information on the tag, and obtains the pre-assigned corresponding receiver by obtaining the torpedo tanker number. The transmitter changes its own channel according to the preset receiver to make the channel the same as the pre-assigned receiver channel, thereby achieving mutual communication between the two on a unique channel not occupied by other signals.

[0049] Step 3: The transmitter enters the standby controlled state and transmits information to the receiver, which is then pushed to the display or communication device through the relay;

[0050] Specifically, the receiver is connected to a display or communication device via two relays. At the same time, in order to ensure that the transmitter can communicate normally, the transmitter needs to enter a standby controlled state, specifically including: the transmitter is fed to the receiver via a first enable terminal and a second enable terminal in sequence; when the receiver receives the first enable terminal and the second enable terminal fed by the transmitter, the transmitter enters a standby controlled state;

[0051] For example, the transmitter end includes a 2-way switch signal input collector (i.e., the first enable end and the second enable end), and only after the first enable end and the second enable end are input at the same time, the transmitter officially enters the standby controlled state. When the host computer inputs the control instruction of the first enable end of the transmitter, it transmits it to the first enable end output of the receiver. When the host computer inputs the instruction of the second enable end of the transmitter, the transmitter transmits the signal to the second enable end output of the receiver. The first enable end of the receiver corresponds to 1 normally open point + 1 normally closed point. After the instruction of the first enable end is received, the normally open point is connected and the normally closed point is disconnected; the second enable end of the receiver is 1 normally open After receiving the instruction from the second enable terminal of the transmitter, the normally open point relay of the second enable terminal of the receiver is closed and connected; as long as either the first enable terminal or the second enable terminal is not input, the transmitter must not transmit the signal; in order to facilitate intuitive observation, the first enable terminal and the second enable terminal each correspond to an LED indicator, and only when the first enable terminal is input first, the second enable terminal input is valid. If the first enable terminal signal is not input, the second enable terminal signal cannot be sent out even if it is triggered; the first enable terminal is in a holding state, and the second enable terminal is in a quasi-inching state.

[0052] In addition, the transmitter receives information read and written by the RFID reader for 255 seconds. If the RFID reader and tag are disconnected and not reconnected during this time, the transmitter automatically clears the information read and written by the RFID reader. That is, if the tag recognizes a disconnected state within the 255-second receiving time of the transmitter, if it is reconnected within this period, or remains in a linked state, the transmitter and receiver will continue to maintain a controlled state. If they are disconnected and not reconnected within this period, once 255 seconds have passed, the tag's memory will be cleared and the next controlled state will be entered. At the same time point, only one tag can be identified.

[0053] Step 4: The display or communication device receives the information and calls the corresponding cover to close it on the torpedo tank car.

[0054] In order to ensure that the RFID reader can accurately identify labels on the surface of torpedo tankers of different models and sizes, the method of the present invention further includes:

[0055] Detecting the actual height of the torpedo tank truck through the detection module and obtaining a picture of the torpedo tank truck;

[0056] The position of the torpedo tanker label is calculated by a control module using a picture of the torpedo tanker and the actual height of the torpedo tanker. Specifically, the position includes: extracting the image outline on the picture through an image recognition and extraction unit; and obtaining the actual label position according to the image outline of the picture and the actual height of the torpedo tanker in proportion.

[0057] According to the position of the torpedo tanker label, the position of the RFID reader is adjusted by the height adjustment component and the horizontal adjustment component so that the RFID reader is opposite to the label.

[0058] The structures of the detection module, the height adjustment component and the level adjustment component are as follows: Figure 2 and 3 As shown,

[0059] A gate 7 is provided in the detection area 9, and a detection module 1 is provided at one end away from the gate 7, wherein the detection module 1 includes a camera 11 for obtaining a picture of the torpedo tanker and a height detector 12 for obtaining the height of the torpedo tanker. The side of the detection area 9 is also provided with a height adjustment component 4 and a level adjustment component 8 for adjusting the position of the RFID reader 5, wherein the height adjustment component 4 includes a motor 41, a screw 42, a nut 43, and a fixing shell 44, wherein the motor 41 is connected to the screw 42, and the screw 42 is connected to the nut 43, and the nut 43 is provided with an RFID reader. The RFID reader 5 is fixed in the fixed housing 44. The RFID reader 5 is raised and lowered by the principle of a ball screw. The horizontal adjustment assembly 8 includes a pneumatic slider 82 and a pneumatic slide rail 81. The pneumatic slider 82 is slidably connected to the pneumatic slide rail 81. The pneumatic slider 82 can slide on the surface of the pneumatic slide rail 81. The side of the pneumatic slider 82 is connected to the RFID reader 5 through the height adjustment assembly 4, thereby adjusting the horizontal position of the RFID reader 5. The side of the RFID reader is connected to the transmitter 6 via a wire.

[0060] In an implementation case, a remote control system involves 73 transmitters and 16 receivers, and specifies receivers for torpedo tank trucks with different numbers. During inspection, the torpedo tank truck 2 enters the inspection area 9. The camera 11 and height detector 12 in the inspection module 1 detect the image and height of the torpedo tank truck 2 and promptly calculate the position of the tag 3. The control module then controls the horizontal adjustment component 8 and the height adjustment component 4 to adjust the position of the radio frequency identification reader 5 so that it reaches the side of the tag 3 and identifies the tag 3. The radio frequency identification reader 5 identifies the number of the torpedo tank truck 2 and other information on the tag 3 and transmits it to the transmitter. After obtaining the information, the transmitter changes the channel to be in the same channel as the specified receiver and transmits the information. Finally, the information is sent to the display or communication device through a relay. The display or communication device receives the information and calls the corresponding cover to be closed on the torpedo tank truck.

[0061] The present invention uses a radio frequency identification method to identify the side tag of a torpedo tank truck to obtain information about the torpedo tank truck, and changes the channel of the transmitter to make it and the pre-configured receiver on the same channel, so that the two can communicate with each other on a unique channel without being occupied by other signals, and call the corresponding cover to close the cover; the present invention has a high degree of automation, does not require human intervention, has a low fault tolerance rate, and is highly efficient;

[0062] The radio frequency identification reader / writer housing of the present invention is adjusted according to the position of the tag so as to read the tag at the best position and ensure the accuracy of the acquired information.
