[0034] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0035] An underwater thruster rental order processing system is provided in an embodiment of the present application, which is applied to an underwater thruster rental cabinet. The underwater thruster rental cabinet is provided with a plurality of return bins. Each return bin is used to store an underwater thruster or an underwater thruster battery. An electronic tag is arranged in each underwater thruster, and an electronic tag is arranged in each underwater thruster battery. An electronic tag reader and an equipment sensing sensor are arranged in each return bin. Figure 1 As shown in FIG. 1, the underwater thruster rental order processing system provided in the embodiment of the present application includes a central processing unit arranged in the interior of the underwater thruster rental cabinet, and a terminal processing unit arranged in the interior of each return bin. The central processing unit is in communication connection with each terminal processing unit.

[0036] The terminal processing unit is used to start the equipment sensing sensor and the electronic tag reader in the return bin when it is detected that the return bin satisfies the warehousing sensing condition. Based on the real-time sensing signal of the equipment sensing sensor and the real-time reading signal of the electronic tag reader, the type and information of the rental equipment warehoused in the return bin are identified and sent to the central processing unit. The type of the rental equipment includes an underwater thruster and / or an underwater thruster battery. The information of the rental equipment includes the number and identification of the rental equipment.

[0037] The central processing unit is configured to receive the returned storage-in storage-out rental equipment type and rental equipment information sent by the terminal processing unit, determine a target rental order from each uncompleted rental order based on the storage-in rental equipment type and rental equipment information, compare the storage-in rental equipment type and rental equipment information with the storage-out rental equipment type and rental equipment information associated with the target rental order to obtain a returned comparison result, and determine a rental equipment return result of the target rental order based on the returned comparison result.

[0038] In the embodiments of the present application, a device sensing sensor and an electronic tag reader are arranged inside each return storage, and an electronic tag is arranged inside each underwater thruster and an electronic tag is arranged inside each underwater thruster battery, wherein the device sensing sensor includes at least one of an ultrasonic sensor, a millimeter wave radar sensor, a ToF camera, and a laser ranging sensor; the electronic tag includes an RFID tag or a two-dimensional code, and correspondingly, the electronic tag reader includes an RFID card reader or a two-dimensional code scanner. In this way, by arranging the device sensing sensor and the electronic tag reader inside each return storage, and arranging the electronic tag inside each underwater thruster and the electronic tag inside each underwater thruster battery, a dual sensing of the electronic tag reader and the device sensing sensor is constructed, so that the dual sensing of the electronic tag reader and the device sensing sensor can be used to accurately identify the number and identification of the rental equipment of the underwater thruster and / or the underwater thruster battery, effectively improving the identification accuracy of the storage-in equipment, and thus when comparing the storage-in rental equipment type and rental equipment information with the storage-out rental equipment type and rental equipment information associated with the target rental order, a more accurate returned comparison result can be obtained, effectively improving the identification accuracy of the rental equipment return result and reducing the misjudgment rate. Moreover, by arranging the electronic tag inside each underwater thruster and each underwater thruster battery and arranging the electronic tag reader and the device sensing sensor inside each return storage, oxidation, damage, and the like can be avoided, thereby effectively reducing the subsequent maintenance and operation costs.

[0039] In a possible implementation, the central processing unit is further configured to, in response to a rental operation performed on the human-computer interaction interface, determine a rental equipment type and a rental equipment number corresponding to the rental operation, determine a return storage to be stored out from the plurality of return storages according to the rental equipment type and the rental equipment number, and send a storage-out instruction to the terminal processing unit inside the return storage to be stored out; and when receiving the storage-out rental equipment type and rental equipment information of the return storage sent by the terminal processing unit, generate a rental order based on the storage-out rental equipment type and rental equipment information and save the rental order.

[0040] The terminal processing unit is further configured to, when receiving the warehouse-out instruction issued by the central processing unit, start the device sensing sensor and the electronic tag reader inside the return warehouse where the terminal processing unit is located; identify the type and information of the rented device that is to be taken out of the return warehouse based on real-time sensing signals of the device sensing sensor and real-time reading signals of the electronic tag reader, and send the type and information of the rented device to the central processing unit.

[0041] In the embodiments of the present application, a user can perform a rental operation on the man-machine interactive interface, and select the type and quantity of the rented device, for example, one underwater thruster and one or more underwater thruster batteries. The central processing unit can determine the type and quantity of the rented device corresponding to the rental operation performed by the user on the man-machine interactive interface, so as to determine the return warehouse to be taken out of the warehouse from the plurality of return warehouses according to the type and quantity of the rented device, based on the type of the rented device stored in the plurality of return warehouses and the current storage state (empty or full) of the plurality of return warehouses, and issue a warehouse-out instruction to the terminal processing unit inside the return warehouse to be taken out of the warehouse, so as to trigger the terminal processing unit to identify the type and information of the rented device that is to be taken out of the return warehouse based on real-time sensing signals of the device sensing sensor and real-time reading signals of the electronic tag reader, and send the type and information of the rented device to the central processing unit. Then, the central processing unit can generate a rental order based on the type and information of the rented device that is to be taken out of the warehouse.

[0042] In a possible implementation, each return warehouse is provided with a warehouse door, and the warehouse door is provided with a door lock switch sensor;

[0043] The central processing unit is configured to, in response to a return operation performed on the man-machine interactive interface, determine a return warehouse to be taken into the warehouse from the plurality of return warehouses, and issue a warehouse-in instruction to the terminal processing unit inside the return warehouse to be taken into the warehouse.

[0044] The terminal processing unit is configured to, when receiving the warehouse-in instruction issued by the central processing unit, control the warehouse door of the return warehouse where the terminal processing unit is located to open, and determine that the return warehouse where the terminal processing unit is located meets the warehouse-in sensing condition when receiving real-time warehouse opening sensing signals of the door lock switch sensor.

[0045] In the implementation of the present application, the user can perform a return operation in the human-computer interaction interface, for example, select a type of rental equipment to be returned or input a rental order number. The central processing unit can determine the type of rental equipment to be returned or the rental order number according to the return operation performed by the user in the human-computer interaction interface. Thus, the type of rental equipment corresponding to the type of rental equipment to be returned or the rental order number can be determined. Based on the types of rental equipment stored in the plurality of return bins and the current storage state (empty bin or full bin) of the plurality of return bins, a return bin to be entered can be determined from the plurality of return bins. Then, an entry instruction is issued to the terminal processing unit inside the return bin to be entered to trigger the terminal processing unit to control the opening of the bin door of the return bin where the terminal processing unit is located. When a real-time bin opening sensing signal of the door lock switch sensor is received, the device sensing sensor and the electronic tag reader inside the return bin are started to perform device sensing. In this way, by guiding the user to put the rental equipment to be returned into the specified return bin during the return, the user's random placement can be effectively prevented, and the difficulty of subsequent device identification is reduced.

[0046] In a possible implementation, the underwater propeller rental order processing system provided by the embodiment of the present application further includes a camera arranged inside the underwater propeller rental cabinet and a hyperspectral imager arranged at the top of each return bin; the camera is in communication connection with the central processing unit, and the hyperspectral imager is in communication connection with the terminal processing unit.

[0047] The terminal processing unit is configured to start the device sensing sensor, the electronic tag reader and the hyperspectral imager inside the return bin when it is detected that the return bin where the terminal processing unit is located meets the entry sensing condition; identify the type of rental equipment and the rental equipment information of the rental equipment entered into the return bin based on a real-time sensing signal of the device sensing sensor and a real-time reading signal of the electronic tag reader; identify surface texture data of the rental equipment entered into the return bin based on real-time imaging data of the hyperspectral imager; and send the type of rental equipment, the rental equipment information and the surface texture data of the rental equipment entered into the return bin to the central processing unit.

[0048] The central processing unit is configured to determine a target rental order from each uncompleted rental order based on the type of rental equipment and the rental equipment information of the rental equipment entered into the return bin when the type of rental equipment, the rental equipment information and the surface texture data of the rental equipment entered into the return bin are received from the terminal processing unit; compare the type of rental equipment, the rental equipment information and the surface texture data of the rental equipment entered into the return bin with the type of rental equipment, the rental equipment information and the surface texture data of the rental equipment associated with the target rental order to obtain a return comparison result; and determine a rental equipment return result of the target rental order based on the return comparison result.

[0049] In the embodiments of the present application, the user's biological characteristics such as face and fingerprint are collected by the camera when the rental equipment is returned to the warehouse, and are bound with the rental order. The consistency of the biological characteristics is verified again when the rental equipment is returned to the warehouse, so as to ensure that the user, the rental equipment and the rental order match each other. In addition, a hyperspectral imager is additionally arranged in the warehouse, which scans the surface texture data of the rental equipment (such as the wear marks of the underwater thruster and the injection texture of the battery), so as to generate a unique physical fingerprint. The surface texture data of the rental equipment scanned when the rental equipment is returned to the warehouse is compared with the surface texture data scanned when the rental equipment is returned to the warehouse, so as to prevent the behavior of replacing the rental equipment of the same type. In this way, by combining the biological recognition characteristics and the equipment texture characteristics with the type of the rental equipment and the information of the rental equipment for return verification, the behavior of replacing the rental equipment can be effectively avoided.

[0050] In a possible implementation, the central processing unit is configured to, when it is determined that the target rental order has unreturned rental equipment based on the return comparison result, mark the device state of the unreturned rental equipment as a missing state, and output a missing prompt information; wherein the missing prompt information at least includes the type of the unreturned rental equipment, a return grace period and a missing compensation fee.

[0051] In the embodiments of the present application, if the user only returns part of the equipment (such as only returns the underwater thruster or the underwater thruster battery), the central processing unit automatically calculates the rental fee of the returned rental equipment, marks the device state of the unreturned rental equipment as a missing state, and notifies the user to return as soon as possible or handle it as a missing through the missing prompt information, for example, sets a return grace period, and if the return grace period is exceeded, the missing compensation fee will be deducted.

[0052] In a possible implementation, the terminal processing unit is configured to, when it is determined that at least two rental equipment are stored in the return warehouse based on the real-time sensing signal of the device sensing sensor and the real-time reading signal of the electronic tag reader, output a replay prompt information; wherein the replay prompt information is used to prompt that the at least two rental equipment are respectively stored in different return warehouses.

[0053] In the embodiments of the present application, if it is identified that the underwater thruster and the underwater thruster battery, or at least two underwater thrusters, or at least two underwater thruster batteries are stored in the return warehouse based on the real-time sensing signal of the device sensing sensor and the real-time reading signal of the electronic tag reader, the charging is performed according to the rental rules, and the user is prompted to return separately. For example, one underwater thruster and one underwater thruster battery are detected in one return warehouse at the same time. If the type and the number of the rental equipment correspond to the rental order, the charging is performed according to the rental rules, and the user is prompted to return separately. If the type and the number of the rental equipment do not correspond to the rental order, the user is reminded to return again, and the subsequent rental permission of the user may be suspended.

[0054] In a possible implementation, the central processing unit is further configured to periodically perform statistical analysis on the rental data, the return data and the device state data of historical rental orders to obtain rental demand data, and optimize the rental strategy and the device configuration based on the rental demand data.

[0055] In the embodiments of the present application, the rental data includes but is not limited to rental time, rental device type, rental device information, etc.; the return data includes but is not limited to return time, return position, state of returned device (such as remaining power), etc.; and the device state data includes but is not limited to whether rented, lost or damaged, etc. The central processing unit can obtain rental demand data of the underwater thrusters and underwater thruster batteries for the delivery site by periodically performing statistical analysis on the rental data, the return data and the device state data of historical rental orders, so as to optimize the rental strategy and the device configuration according to the rental demand data, such as reasonably adjusting the number ratio of underwater thrusters and underwater thruster batteries in the rental cabinet according to the rental demand of different time periods and locations, further improving the intelligent level and operation efficiency of the underwater thruster rental cabinet, and improving user experience and economic benefits.

[0056] In a possible implementation, the terminal processing unit is further configured to, if it is determined according to the real-time reading signal of the electronic tag reader that the electronic tag reader has not successfully read the device information stored in the electronic tag inside the underwater thruster or underwater thruster battery, gradually increase the transmission power of the electronic tag reader according to a power increment strategy, and report no device information to the central processing unit when the device information stored in the electronic tag inside the underwater thruster or underwater thruster battery is still not successfully read after the transmission power is increased to the maximum transmission power.

[0057] In the embodiments of the present application, when the electronic tag reader has not successfully read the device information stored in the electronic tag inside the underwater thruster or underwater thruster battery, the transmission power of the electronic tag reader is gradually increased according to a power increment strategy for re-reading, and it is determined that the reading fails only when the device information stored in the electronic tag inside the underwater thruster or underwater thruster battery is still not successfully read after the transmission power is increased to the maximum transmission power, which can significantly reduce false positives and false negatives.

[0058] In a possible implementation, the terminal processing unit is further configured to: if it is determined, according to the real-time reading signal of the electronic tag reader, that the electronic tag reader successfully reads the device information stored in the electronic tag inside the underwater propeller or the underwater propeller battery, compare the device information with the in-warehouse device information, and determine, according to a comparison result, that the returned rental device in the return warehouse is the underwater propeller or the underwater propeller battery when the device information is not recorded in the in-warehouse device information, and determine, according to the comparison result, that the returned rental device in the return warehouse is not the underwater propeller or the underwater propeller battery when the device information is recorded in the in-warehouse device information; notify terminal processing units inside each surrounding return warehouse to start the electronic tag reader, receive device information stored in the electronic tag inside the underwater propeller and the underwater propeller battery successfully read by the electronic tag reader reported by the terminal processing unit inside any surrounding return warehouse, and determine, when the device information is not recorded in the in-warehouse device information, that the returned rental device in the return warehouse is the underwater propeller or the underwater propeller battery; and determine, when the device information successfully read by the electronic tag reader reported by the terminal processing unit inside all surrounding return warehouses is all recorded in the in-warehouse device information, that the returned rental device in the return warehouse is not the underwater propeller or the underwater propeller battery.

[0059] In the implementation of the present application, when a repeated or no-tag event occurs, the surrounding return warehouse linkage arbitration mechanism is adopted to trigger the adjacent return warehouse to assist in reading, and problems such as tag drift and return warehouse string reading are solved by using spatial redundancy, so that the accuracy and reliability of return identification can be improved.

[0060] In a possible implementation, the central processing unit is further configured to: construct a digital twin for each rental device to synchronize, in real time, device usage data (such as propeller motor current fluctuation, battery cycle number, etc.) and tag usage data (such as electronic tag usage number, etc.) of each rental device, and predict, by using an LSTM neural network, a device remaining life and a tag remaining life of each rental device; when the device remaining life of the rental device is less than a first life threshold, reduce a current rental of the rental device to a target amount corresponding to a device life interval in which the device remaining life is located, and return, to a user, a life premium token when it is detected that an actual remaining life of the rental device is better than the predicted device remaining life when the rental device is returned; and when the tag remaining life of the rental device is less than a second life threshold, reduce a current return identification confidence of the electronic tag to a tag return identification confidence corresponding to a tag life interval in which the tag remaining life is located, and increase a current return identification confidence of the device perception sensor to a sensor return identification confidence corresponding to the tag life interval in which the tag remaining life is located.

[0061] In the embodiments of the present application, by constructing a digital twin for each rental device to synchronize the device usage data (such as thruster motor current fluctuation, battery cycle number, etc.) and tag usage data (such as electronic tag usage number, etc.) of each rental device in real time, and predicting the device remaining life and tag remaining life of each rental device through the LSTM neural network, the rental of the rental device can be reduced (such as the rental of a device with 50% of the remaining life is reduced by 30%) when the device remaining life of the rental device is less than a first life threshold (for example, <10%), and the user can be returned a life premium token (which can be used for next rental discount) when the actual remaining life of the rental device is better than the predicted device remaining life (such as the battery capacity is better than expected) upon return. In addition, the return recognition confidence of the electronic tag can be reduced (such as from 95% to 70%) and the return recognition confidence of the device perception sensor can be increased (such as from 70% to 95%) when the tag remaining life of the rental device is less than a second life threshold (for example, <10%), so as to compensate for the recognition risk caused by the impending failure of the electronic tag. In this way, by coupling the device life and tag life prediction with the device recognition algorithm, the mutual coordination of life, pricing and recognition can be achieved, thereby improving the accuracy of rental order processing.

[0062] In a possible implementation, the central processing unit inside each underwater thruster rental cabinet serves as a light node, writes log data of rental orders into a blockchain in real time, automatically calculates rental fees by using a smart contract, and performs cross-region return verification by using zero-knowledge proof technology.

[0063] In the embodiments of the present application, the central processing unit inside each underwater thruster rental cabinet serves as a light node, writes log data such as device identification, rental / return time, rental cabinet coordinates, and in-cabinet photo hash of rental orders into a blockchain (such as Polygon), can automatically calculate rental fees by using a smart contract, and eliminate the problem of centralized tampering. In addition, cross-region return verification can be performed by using zero-knowledge proof technology, which can solve the problem of data island in cross-region return and improve the verifiability of cross-region return.

[0064] In addition, the embodiments of the present application also provide an underwater thruster rental cabinet, as shown in Figure 2 The underwater thruster rental cabinet provided by the embodiments of the present application includes a plurality of return bins and the above-mentioned underwater thruster rental order processing system; wherein each return bin is used for storing an underwater thruster or an underwater thruster battery, each underwater thruster and each underwater thruster battery is internally provided with an electronic tag, and each return bin is internally provided with an electronic tag reader and a device perception sensor.
