Background Art

[0002] In recent years, radio frequency identification (RFID) technology has shown great potential in the fields of material tracking and inventory management due to its advantages such as non-contact identification, fast identification speed, high accuracy, and simple operation. However, the application of RFID technology in the field of equipment management still faces some challenges.

[0003] Equipment is usually stored in equipment cabinets or equipment racks with limited space and complex environments, such as metal materials and electromagnetic interference, which may affect the recognition effect of RFID tags. Secondly, equipment management has extremely high requirements for security and accuracy. Any recognition errors or data leakage may have serious consequences. Therefore, how to overcome the influence of complex environments in a limited space, achieve efficient and stable RFID recognition, and ensure the security and integrity of data has become an urgent problem to be solved. Summary of the invention

[0004] The main purpose of the present invention is to provide a method and device for accurately locating and identifying the equipment's return and departure positions, so as to achieve standardized one-to-one management of the equipment storage rack positions, accurately locate and identify the equipment's position when it is taken from the equipment rack, and ensure that the equipment is placed in the correct corresponding position on the equipment rack.

[0005] To achieve the above object, the present invention provides a method for accurately locating and identifying the position of equipment in a homing state and out of a homing state, comprising the following steps: Obtaining an ID number of an in-situ detection device, wherein the ID number of the in-situ detection device is pre-associated with a position number of an equipment rack; The first position information of the equipment in the equipment rack is determined by the ID number of the in-position detection device; the equipment rack is provided with a plurality of numbered equipment placement positions, each of which is provided with an in-position detection device, and when the in-position detection device of the equipment placement position detects that the equipment is placed in or out of position, the position information of the current equipment placement is determined according to the ID of the in-position detection device; The tag on the equipment is read by an RFID phased-control antenna, wherein the RFID phased-control antenna is a phased-control planar array antenna with relatively uniform radiation intensity distribution in the near and mid-fields, and the inconsistency of the radiation intensity distribution is less than ±2.5dBV / m; Determining whether the TID or EPC number of the tag matches the first position information, the TID or EPC number of the tag on the equipment being pre-associated with the position and equipment number in the equipment rack; If there is no match, matching the second position of the pre-associated equipment in the equipment rack based on the tag TID or EPC number, and generating a second position signal; Based on the second position signal, a reminder instruction is generated, and the corresponding light unit and sound unit are activated by the reminder instruction.

[0006] Furthermore, the step of reading the tag on the equipment by the RFID phased antenna includes: The RFID tag on the equipment is read through the RFID phased antenna to obtain the TID or EPC number of the equipment.

[0007] Furthermore, the step of reading the tag on the equipment by using the RFID phased antenna also includes: Read the TID or EPC number and RSSI value of the tag on the equipment through the RFID phased antenna; Based on the RSSI value of the tag and the pre-associated ID number of the presence detection device, the location information of the current equipment returning to the position is determined from the tag information of multiple equipments.

[0008] Furthermore, the step of reading the tag on the equipment by using the RFID phased array antenna also includes: The RSSI value of the tag on the equipment is identified by the RFID phased array antenna, where the RSSI is the signal strength returned by the tag; According to the formula of RSSI and distance, the distance values ​​between multiple equipped tags and RFID phased antenna are calculated.

[0009] Furthermore, the formula of RSSI and distance is:

[0010] Where P(d) represents the signal strength received by the receiver when the distance from the transmitter is d, that is, the RSSI value; P(d0) represents the signal power received by the receiver when the distance from the transmitter is d0, d0 is the reference distance, n is the path loss index, and σ is a Gaussian random variable with a unit of dBm and an average value of 0; The relationship between distance and RSSI is calculated based on the RSSI algorithm:

[0011] A is the RSSI value received by the receiving node when the wireless transceiver nodes are 1 m apart, and d is the distance between the equipment tag and the RFID phased antenna.

[0012] Further, after the step of calculating the distance values ​​between the tags of multiple devices and the RFID phased antenna according to the formula of RSSI and distance, the method further comprises: When the near-field radiation intensity distribution in the RFID antenna is relatively uniform, the positive correlation between the distance d between the RFID phased antenna and the tag on the equipment and the RSSI, as well as the characteristics of the close-range equipment presence detection device, are used to determine the TID or EPC number of the currently stored equipment, and locate the position information on the equipment rack corresponding to the currently returned or unlocated equipment.

[0013] Further, after the step of obtaining the ID number of the in-situ detection device, wherein the ID number of the in-situ detection device is preliminarily associated with the position number of the equipment rack, the method further includes: Obtain equipment identity and return and departure position information through the equipment positioning and identification detection network on the equipment rack; Analyze the equipment usage patterns and storage anomalies through machine learning algorithms, and intelligently locate and identify the identity information of the equipment and its location information in the equipment rack. The equipment positioning and identification detection network includes an in-place detection device, an RFID reader and writer, and an RFID phased antenna, wherein the in-place detection device is installed at each equipment storage position of the equipment rack, and sends out signals in real time and continuously to detect whether there is equipment returning to or leaving its position. When it is detected that equipment has returned to or left its position, the equipment return and departure position information is generated through the in-place detection device ID.

[0014] The present invention also provides a device for accurately locating and identifying the position of equipment in a homing state and out of a homing state, comprising: An in-place detection module is used to obtain an in-place detection device ID number, wherein the in-place detection device ID number is pre-associated with a position number of an equipment rack; An information identification module is used to determine the first position information of the equipment in the equipment rack by using the ID number of the in-position detection device; the equipment rack is provided with a plurality of numbered equipment placement positions, each of which is provided with an in-position detection device, and when the in-position detection device of the equipment placement position detects that the equipment is placed in or out of position, the position information of the current equipment placement is determined according to the ID of the in-position detection device; An RFID sensing module is used to read the tag on the equipment through an RFID phased-control antenna. The RFID phased-control antenna is a phased-control planar array antenna with relatively uniform radiation intensity distribution in the near and mid-fields, and the inconsistency of the radiation intensity distribution is less than ±2.5dBV / m. An information matching module, used to determine whether the TID or EPC number of the tag matches the first position information, the TID or EPC number of the tag on the equipment being pre-associated with the position in the equipment rack and the equipment number; An information generating module, configured to match a second position of the pre-associated equipment in the equipment rack based on the tag TID or EPC number, and generate a second position signal; The signal indication module is used to generate a reminder instruction based on the second position signal, and start the corresponding light unit and sound unit through the reminder instruction.

[0015] The present invention also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, the steps of the above-mentioned method for accurately locating and identifying the equipment's homing and out-of-position positions are implemented.

[0016] The present invention also provides a computer-readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, the steps of the above-mentioned method for accurately locating and identifying the position of the equipment when it is in the home position and out of the home position are implemented.

[0017] The method and device for accurately locating and identifying the equipment homing and out-of-position positions provided by the present invention have the following beneficial effects: (1) By pre-associating the in-place detection device ID with the equipment rack position number, and combining the RFID phased antenna to read the equipment tag information and match it, the position of the equipment in the equipment rack can be determined from multiple dimensions. The setting of the in-place detection device at the equipment placement position enables the immediate acquisition of position information when the equipment is returned or removed, and the tag information read by the RFID phased antenna further accurately verifies the position. For example, when many similar equipment are stored in a large warehouse, this dual positioning method can effectively avoid positioning errors caused by human negligence or environmental factors, ensuring that the equipment is always in a state of accurate monitoring.

[0018] (2) Accurate positioning and identification helps to achieve standardized management of equipment storage. The storage location of the equipment and its return or removal status can be quickly known, reducing the time spent on finding equipment and improving the efficiency of daily equipment management. In industrial production, if the tools or spare parts on the production line can be accurately located, they can be quickly obtained when needed, improving the continuity and efficiency of the entire production process. At the same time, the inventory, scheduling and other management tasks of equipment have become more convenient and efficient, and managers can make reasonable resource allocation based on accurate location information.

[0019] (3) When the TID or EPC number of the tag does not match the location information determined by the in-situ detection device, a reminder instruction can be generated in time and the light and sound units can be activated. This mechanism is of great significance for standardizing the storage and retrieval of equipment. In some scenarios with strict requirements on operating procedures, such as the management of chemical reagents or precision instruments in laboratories, irregular storage or retrieval may cause safety accidents or experimental failures. This method can effectively supervise operators to ensure that they operate the equipment in accordance with the prescribed procedures, thereby ensuring the safety and reliability of the entire operating environment.

[0021] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1 , which is a flow chart of a method for accurately locating and identifying the position of equipment in a homing state and out of a homing state proposed by the present invention, comprising the following steps: S1, obtaining the ID number of the in-situ detection device, wherein the ID number of the in-situ detection device is pre-associated with the position number of the equipment rack; S2, determining the first position information of the equipment in the equipment rack by the ID number of the in-position detection device; the equipment rack is provided with a plurality of numbered equipment placement positions, each of which is provided with an in-position detection device, and when the in-position detection device of the equipment placement position detects that the equipment is placed in or out of position, the position information of the current equipment placement is determined according to the ID of the in-position detection device; S3, reading the tag on the equipment by using an RFID phased-control antenna, wherein the RFID phased-control antenna is a phased-control planar array antenna with relatively uniform radiation intensity distribution in the near and mid-fields, and the inconsistency of the radiation intensity distribution is less than ±2.5 dBV / m; S4, determining whether the TID or EPC number of the tag matches the first position information, the TID or EPC number of the tag on the equipment being pre-associated with the position in the equipment rack and the equipment number; S5, if there is no match, matching the second position of the pre-associated equipment in the equipment rack based on the tag TID or EPC number, and generating a second position signal; S6: Generate a reminder instruction based on the second position signal, and activate the corresponding light unit and sound unit through the reminder instruction.

[0024] As described in step S1 above, the ID number of the in-place detection device is obtained, and the ID number of the in-place detection device is pre-associated with the position number of the equipment rack. Among them, the in-place detection device is arranged at each return position of the equipment rack, and is a device used to detect whether there is equipment at the corresponding position (i.e., return to position) or whether the equipment is taken away (i.e., out of position), and has a unique identification number (ID number); in the construction of the entire equipment management system, a corresponding relationship is established between the ID number of each in-place detection device and the specific position number on the equipment rack through a certain configuration program. For example, an equipment rack has multiple layers and columns of storage grids (return positions), which are marked as grid 1, grid 2, etc. (these are the position numbers). The ID number of the in-place detection device installed at grid 1 is associated with the position number "grid 1", which is convenient for the subsequent accurate positioning of which specific position has undergone the return or out-of-position change of the equipment according to the situation of the detection device.

[0025] As described in step S2 above, the first position information of the equipment in the equipment rack is determined by the ID number of the in-place detection device; the equipment rack is provided with a plurality of numbered equipment placement positions, and each of the equipment placement positions is provided with an in-place detection device. When the in-place detection device of the equipment placement position detects that the equipment is returned to or out of position, the position information of the current equipment return to or out of position is determined according to the ID of the in-place detection device. Among them, each equipment placement position is equipped with an in-place detection device, and these devices have their own ID numbers, and correspond one-to-one with the position of the equipment rack. When the in-place detection device of a placement position detects that the equipment has returned to or out of position, the ID number of this device can be used to determine the position of the equipment rack at this moment. For example, the in-place detection device of placement position No. 3 detects that the equipment has changed, then according to its ID, it can be known that the equipment is at position No. 3 of the equipment rack to determine the first position information of the equipment.

[0026] As described in the above step S3, the tag on the equipment is read by the RFID phased antenna, and the RFID phased antenna is a phased array planar array antenna with relatively uniform radiation field strength distribution in the near and mid-fields, and the inconsistency of the field strength radiation distribution is less than ±2.5dBV / m. Among them, the reading of the tag on the equipment by the RFID phased antenna refers to using the RFID phased antenna to obtain the relevant information carried by the RFID electronic tag installed on the equipment. The RFID phased antenna is used to read the equipment tag information, which contains codes that can identify key content such as the identity of the equipment. Among them, the RFID phased antenna is mainly used to transmit and receive signals to realize the reading of tag information. In the working near and mid-field area, the electromagnetic field strength radiated by the RFID phased antenna is relatively evenly distributed in each plane from the antenna surface, and there will be no situation where the field strength is very strong in some places and very weak in others. To put it in specific terms, the inconsistency of its field strength radiation distribution is less than ±2.5dBV / m, which means that the actual field strength fluctuates within ±2.5dBV / m compared with a standard reference field strength. This ensures that no matter where the tag on the equipment is located in the near-field radiation area of ​​the antenna, the field strength when the tag is activated is relatively consistent, and the information can be read by the antenna more reliably and accurately, which helps to improve the success rate and accuracy of tag information reading.

[0027] As described in the above step S4, it is determined whether the TID or EPC number of the tag matches the first position information, and the TID or EPC number of the tag on the equipment is pre-associated with the position in the equipment rack and the equipment number. The tag information (TID number or EPC number) read from the equipment and the "first position information" of the equipment in the equipment rack previously determined by the in-place detection device are checked to see if the two are consistent with each other. When the entire equipment management system is set up, a corresponding relationship has been established between the TID number or EPC number of the tag on each piece of equipment and the specific position and equipment number where it should be placed on the equipment rack. For example, the TID number of the tag on a piece of equipment corresponds to the No. 5 placement position on the equipment rack.

[0028] As described in the above step S5, if there is no match, the second position of the pre-associated equipment in the equipment rack is matched based on the tag TID or EPC number, and a second position signal is generated. If the TID or EPC number of the tag on the equipment is inconsistent with the first position information determined by the in-place detection device, it means that the current position of the equipment may not be the correct position where it should be placed, and the misplacement occurs. Although the current position of the equipment is wrong, since the tag TID or EPC number of each equipment has been pre-associated with a specific position in the equipment rack when the system is initially set, it can rely on the existing association relationship and use the existing TID or EPC number of the equipment tag to find and determine the correct position where it should be placed on the equipment rack. This correct position is the "second position". After determining this correct second position, the system will generate a corresponding electrical signal or data signal (second position signal) to identify this correct position information. This signal can be subsequently received and processed by other modules in the system, such as used to prompt the operator where to put the equipment correctly, or stored as record information to facilitate subsequent further management and adjustment of the equipment position.

[0029] As described in step S6 above, based on the second position signal, a reminder instruction is generated, and the corresponding light unit and sound unit are activated by the reminder instruction. When the system obtains a signal representing the correct position of the equipment (that is, the second position), it will generate an instruction information for reminding relevant personnel based on this signal. This reminder instruction is essentially a control signal. In the activation of the corresponding light unit and sound unit by the reminder instruction, the light unit is composed of some indicator lights (such as LED lights of different colors, etc.), and the sound unit can be a device that can make sounds such as a buzzer and a speaker. When the reminder instruction is issued, it will trigger the corresponding circuit or control module, so that the light unit starts to light up (for example, a red light is lit to intuitively indicate that an error has occurred), and the sound unit will also emit a corresponding prompt sound (such as a continuous alarm sound or an intermittent prompt sound, etc.), through the two sensory stimulations of vision and hearing, it is more effective to remind the personnel on the scene to pay attention to the fact that the equipment is misplaced, so that they can move the equipment to the correct second position in time according to the prompt, and ensure the accuracy and standardization of equipment management.

[0030] In one embodiment, when the equipment is placed in a certain return position of the equipment rack, the presence detection device of the return position first detects the equipment return operation, generates and obtains the presence detection device ID number. After the presence detection module receives this ID number, the information identification module determines the first position information of the equipment in the equipment rack based on the relationship between the pre-associated presence detection device ID number and the equipment rack position number. At the same time, the RFID sensing module reads the RFID tag information on the equipment through the RFID phased antenna. Specifically, the RFID tag on the equipment is read first to obtain the TID or EPC number of the equipment. At the same time, the RSSI value of the tag is also read, and based on the RSSI value of the tag and the ID number of the presence detection device, the position information of the current equipment return is further determined from the tag information of multiple equipment.

[0031] The information matching module matches the TID or EPC number of the read tag with the previously determined first position information to determine whether it is consistent with the equipment information pre-associated with the position. If the match is successful, it means that the equipment is correctly returned to the position, and the system records the return information and stores the relevant data. If there is no match, the information generation module matches the second position of the pre-associated equipment in the equipment rack based on the tag TID or EPC number, and generates a second position signal. The signal indication module generates a reminder instruction based on the second position signal, and activates the corresponding light unit (such as lighting up a red warning light) and sound unit (emitting an alarm) to remind the staff that the equipment is incorrectly returned and needs to be adjusted.

[0032] When the equipment is removed from a certain storage position on the equipment rack, the in-place detection device detects the equipment removal operation, and also generates an in-place detection device ID number and is obtained by the in-place detection module. The information identification module determines the initial position information of the equipment removal based on the ID number. The RFID sensing module reads the RFID tag information on the equipment through the RFID phased antenna, including the TID or EPC number and RSSI value. The distance value between the equipment tag and the RFID phased antenna is calculated through the formula of RSSI and distance.

[0033] The RSSI (Received Signal Strength Indicator) algorithm is a mathematical model based on the propagation characteristics of wireless signals. It is used to infer relevant information such as distance and object location by the strength of the received signal. The RSSI algorithm is: (1) In the formula, P(d) represents the signal strength received by the receiver when the distance from the transmitter is d, that is, the RSSI value; P(d0) represents the signal power received by the receiver when the distance from the transmitter is d0; d0 is the reference distance; n is the path loss index, which is usually obtained from actual measurements. The more obstacles there are, the larger the n value is, so the speed at which the average energy received decreases will become faster and faster as the distance increases: σ is a Gaussian random variable with a unit of dBm and an average value of 0, which reflects the change in the received energy when the distance is constant. In practical applications, a simplified gradual model is generally used for ease of expression and calculation, and d0 is usually taken as 1 m. So we can get: (2) Writing [P(d)]dBm in RSSI form gives: (3) Where A is the RSSI value received by the receiving node when the wireless transceiver nodes are 1 m apart. Formula (3) is the classic model of RSSI ranging, which gives the functional relationship between RSSI and d. Therefore, if the RSSI value received by the RFID phased antenna is known, the distance between it and the tag on the equipment can be calculated. When the near-field radiation intensity distribution in the RFID antenna is relatively uniform, the positive correlation between the distance d between the RFID phased antenna and the tag on the equipment and RSSI, as well as the characteristics of the close-range equipment in-place detection device, is used to further determine the TID or EPC number of the currently removed equipment, and locate the location information on the equipment rack corresponding to the currently removed equipment, thereby accurately recording the relevant information of the equipment leaving the equipment, including data such as equipment identity and departure location, for subsequent equipment management and tracking.

[0034] In addition, the system can obtain the equipment identity and return and departure location information through the equipment positioning and identification detection network on the equipment rack, and use machine learning algorithms to analyze the equipment usage patterns and storage anomalies. For example, by learning a large amount of equipment return and departure data, the machine learning algorithm can identify uncommon equipment usage times, abnormal equipment storage locations, etc., and intelligently locate and identify the identity information of the returned and departed equipment and the location information in the equipment rack. When an abnormal situation is found, early warning information is issued in a timely manner, further improving the safety and accuracy of equipment management.

[0035] In actual application scenarios, for example, in a military equipment warehouse, many weapons and equipment are stored on specific equipment racks. Through the system of the present invention, it is possible to ensure that each weapon and equipment is accurately placed in the corresponding position when returning to its place, and its identity and location information can be accurately recorded when leaving its place, effectively avoiding safety hazards and management chaos caused by poor equipment management, and greatly improving the efficiency and accuracy of equipment management.
