[0022] In short, the basic technical scheme of the utility model is briefly described as follows: a device for auxiliary positioning of steel pipes, including: a signal beacon 11, a connector, a Bluetooth receiver 13, and a server 14; the signal beacon 11 is fixedly installed on the inner wall of the steel pipe through the connector; a Bluetooth receiver 13 is respectively arranged on both sides or both ends of each storage position of the steel pipe finished product warehouse, the Bluetooth receiver 13 is wirelessly connected with the signal beacon 11, and the signal beacon 11 sends out a Bluetooth signal with data information; the Bluetooth receiver 13 receives the data information of the signal beacon 11; the server 14 is communicatively connected with the Bluetooth receiver 13; the Bluetooth receiver 13 sends the data information to the server 14; the server 14 determines the specific position of each signal beacon 11 according to the data information of multiple Bluetooth receivers 13.

[0023] The present application installs a signal beacon 11 that continuously transmits signals in a steel pipe. The transmitted signal is received by a Bluetooth receiver 13 installed in a fixed position. The Bluetooth receiver 13 sends the received data information to a server 14, and the server determines the specific position of the steel pipe.

[0024] The following is a detailed description of a steel pipe auxiliary positioning device of the present application. The device comprises: the signal beacon 11, the connector, the Bluetooth receiver 13, and the server 14 mentioned in the above embodiment.

[0025] The signal beacon 11, i.e., a wireless Bluetooth device, emits a Bluetooth signal with data information; specifically, the signal beacon 11 continuously emits a periodic signal. The signal beacon 11 is fixedly mounted on the inner wall of the steel pipe through a connector. The signal beacon 11 is fixedly connected to the connector. In one specific embodiment, the signal beacon 11 and the connector are screwed and fixed. In another specific embodiment, the signal beacon 11 and the connector are glued or fixed with a cable tie. Specifically, the signal beacon 11 can be fixedly connected to the connector by glue, adhesive strips, tape, cable ties, magnets, and bolts. The data information of the steel pipe is stored in the signal beacon 11. A battery for providing power is provided in the signal beacon 11. The cross-sectional shape of the signal beacon 11 can be polygonal, circular, or elliptical. Preferably, the cross-sectional shape of the signal beacon 11 is circular.

[0026] There are multiple Bluetooth receivers 13, and Bluetooth receivers 13 are respectively arranged on both sides or both ends of each storage position of the steel pipe finished product warehouse. The Bluetooth receiver 13 is wirelessly connected with the signal marker 11; the signal marker 11 sends out a Bluetooth signal with data information, and the Bluetooth receiver 13 receives the data information of the signal marker 11; it is ensured that the Bluetooth signal sent out by the signal marker 11 of each storage position can be received by the two closest Bluetooth receivers 13, and the Bluetooth receiver 13 covers the entire finished product storage area, that is, there is no blind spot of Bluetooth receiver coverage in the entire finished product storage area. Among them, the more Bluetooth receivers receive the Bluetooth signal sent out by each signal marker 11, the more accurate the position of the obtained signal marker is, and the smaller the error is. A battery for providing power is arranged in the Bluetooth receiver 13. In a specific embodiment, the steel pipes in each storage position are aligned on one side, and the signal marker 11 is placed on one side of the storage position, and the measurement error is small; the distance between the Bluetooth receiver 13 and the signal marker 11 cannot be too far, and it can be installed on both sides of the storage position, or it can be installed at both ends of the storage position, so as to facilitate the reception of Bluetooth signals;

[0027] In a specific embodiment, the finished product storage area is provided with 10 storage locations, and a Bluetooth receiver 13 is provided on both sides of each storage location. The Bluetooth signal emitted by each signal marker 11 is received by at least the two closest Bluetooth receivers. By using each Bluetooth receiver 13 to measure the signal strength emitted from the signal marker 11 in the steel pipe, the distance between the signal marker 11 and the Bluetooth receiver is calculated according to the signal strength, and the position of the signal marker 11 is determined. Specifically, RSSI (Received Signal Strength Indicator) or ToF (Time of Flight) can be used to calculate the distance, determine the position of each signal marker 11, and then locate the specific position of the steel pipe.

[0028] In another specific embodiment, the finished product storage area is provided with 5 storage locations, and a Bluetooth receiver 13 is provided on both sides of each storage location. The Bluetooth signal emitted by each signal beacon 11 is received by at least the three closest Bluetooth receivers. By using each Bluetooth receiver 13 to measure the signal strength emitted from the signal beacon 11 in the steel pipe, the distance between the signal beacon 11 and the Bluetooth receiver is calculated according to the signal strength, and the position of the signal beacon 11 is determined. Specifically, RSSI (Received Signal Strength Indicator) or ToF (Time of Flight) can be used to calculate the distance, determine the position of each signal beacon 11, and then locate the specific position of the steel pipe. The position of the signal beacon obtained when the Bluetooth signal emitted by each signal beacon is received by 3 Bluetooth receivers than when it is received by 2 Bluetooth receivers. The more Bluetooth receivers receive the Bluetooth signal emitted by each signal beacon 11, the more accurate the position of the obtained signal beacon is.

[0029] The Bluetooth receiver 13 is connected to the server 14 in a communication manner (either wired or wireless), and the Bluetooth receiver 13 sends data information to the server 14. The server 14 processes the data information to monitor and manage the steel pipes, which facilitates the staff to manage the steel pipe models, locations, and quantities in real time in the finished product warehouse.

[0030] In a specific embodiment, an analysis module is provided in the Bluetooth receiver, which is used to determine the specific position of the signal beacon 11 according to the strength of the Bluetooth signal received from the signal beacon 11; and the Bluetooth receiver is connected to the Bluetooth receiver for communication.

[0031] In another specific embodiment, the server 14 determines the specific location of each signal marker 11 based on the data information of multiple Bluetooth receivers 13. There may be no analysis module in the Bluetooth receiver, and the server makes a specific analysis and judgment to determine the location of each signal marker 11. In other words, the server can determine the specific location of each signal marker 11 based on the strength of the Bluetooth signal received from each signal marker; specifically, multiple Bluetooth receivers 13 cooperate to locate the signal marker 11 based on the strength of the Bluetooth signal received from each signal marker 11, determine the specific location of the signal marker 11 through an algorithm, and then determine the specific location of the steel pipe and the warehouse number of the steel pipe. The data information sent by the Bluetooth receiver 13 to the server 14 includes the data information of the signal marker 11.

[0032] Preferably, the connecting member is a magnet 12. In a specific embodiment, the magnet 12 is adsorbed on the inner wall of the steel pipe, such as Figure 1As shown. The magnet 12 is installed on the outside of the signal beacon 11. It should be noted that the inner side is closer to the central axis of the steel pipe, and the outer side is farther away from the central axis of the steel pipe. In other words, the signal beacon 11 is fixedly installed in the steel pipe through the magnet 12. There are multiple magnets 12. In order to strengthen the adsorption force and prevent the signal beacon 11 from falling during the lifting of the steel pipe, preferably, two magnets 12 are provided. The magnet 12 is firmly adsorbed in the steel pipe, so that the signal beacon 11 can be lifted together with the steel pipe.

[0033] When in use, the signal marker 11 is placed in the corresponding steel pipe, and at least one signal marker 11 is set for each type of steel pipe. The steel pipe enters the finished product storage area and is placed in the storage location. The Bluetooth signal emitted by each signal marker 11 in the steel pipe is received by the two nearest Bluetooth receivers 13 in the finished product storage area. The position of each signal marker 11 is determined and continuously updated based on the strength of the Bluetooth signal. The position of each signal marker 11 is identified, and then the specific storage location number of the steel pipe where each signal marker is located is obtained.

[0034] In a specific embodiment, before the steel pipe enters the finished product warehouse, the staff uses a handheld device to scan the QR code label to bind each signal mark 11 to the card number of the steel pipe and manually input the number of steel pipes entering the warehouse. The steel pipe is affixed with a QR code label in the finished product packaging process. The information on the QR code label includes the card number, bundle number, number of pieces, length, weight, brand, furnace number, specification, standard, contract number, card date, etc. of the steel pipe. Among them, the card number is the number bound when the steel pipe is produced, which is used to distinguish the steel pipe; this application can read the card number of the steel pipe. The steel pipe enters the finished product warehouse area and is placed in the warehouse. The Bluetooth signal emitted by the signal mark 11 in the steel pipe is received by the nearby Bluetooth receiver 13 in the finished product warehouse area. Multiple Bluetooth receivers 13 cooperate to determine the position of each signal mark 11 according to the strength of the Bluetooth signal received from each signal mark 11, and then determine the position of the steel pipe. Because the signal mark 11 and the card number are bound when the steel pipes are put into storage, the steel pipes in the finished product warehouse are located and managed in real time based on the card number, and updated in real time; that is to say, the management of the steel pipes in the finished product warehouse can accurately obtain the location of the steel pipe (i.e. the warehouse location number of the steel pipe) according to the card number and continuously update it.

[0035] In another specific embodiment, each signal marker 11 is set to a number or name, and corresponds to a certain type of steel pipe. The position of the signal marker 11 is determined according to the strength of the Bluetooth signal received from the signal marker 11; the steel pipes in the finished product warehouse are managed with the signal marker as a unit. For example, by querying the number or name of the signal marker 11, the position of the steel pipe can be easily obtained without binding the card number of the steel pipe; the number or name of the signal marker 11 is defined when the steel pipe is entered into the warehouse, so that the steel pipe information in the finished product warehouse is updated in real time with the signal marker 11 as a unit. After each steel pipe position changes, the server 14 updates the warehouse location number according to the data of the Bluetooth receiver 13 to complete the real-time positioning update of each steel pipe.

[0036] This application is applied to the inventory management of steel pipe finished product warehouse, and successfully realizes the automatic identification of warehouse location number when steel pipe enters the finished product warehouse, and the system quickly locates the position of steel pipe, improves the efficiency of warehouse space utilization, improves the efficiency of search operations, reduces the workload of personnel, and reduces inventory costs. In a specific embodiment, a steel pipe factory uses this device to save 2.17 million yuan in funds for adding warehouse shelves.

[0037] The present application discloses a device for assisting the positioning of steel pipes. The difficulty in finding steel pipes lies in the frequent outbound and inbound movement of steel pipes in the finished product warehouse area, and the location of the steel pipes often changes, making it impossible to quickly and effectively locate the location of the steel pipes. The device places a signal beacon 11 that continuously transmits a Bluetooth signal on the inner wall of the steel pipe. When the steel pipe enters the finished product warehouse area, a Bluetooth receiver 13 installed in the warehouse area receives the Bluetooth signal emitted by the signal beacon 11, and determines the warehouse number of the steel pipe by the strength of the Bluetooth signal, thereby achieving the purpose of locating the steel pipe position and improving work efficiency.
