Description

Technical Field

[0001] This utility model relates to the field of warehouse management, specifically to a weighing system. Background Technology

[0002] The management of goods and items in warehouses and other areas is a process by which enterprises utilize warehouse resources for efficient planning and warehousing services, and it plays a very important role in logistics and economic activities.

[0003] In related technologies, video surveillance is usually used to monitor the entry and exit of goods from and from warehouses. However, in practice, this method is not sufficient to monitor the entry and exit operations. When there is a discrepancy between the weight of the goods and the logistics, if it is necessary to review the entry and exit operations, it is impossible to accurately obtain information such as the weight of the goods by relying solely on video surveillance, which increases the difficulty of supervision. Utility Model Content

[0004] In view of this, the present invention provides a weighing system, comprising:

[0005] The support platform includes a group of support plates and detection components. The support plates and the detection components are configured to transmit force. The detection components are located at the bottom of the support plates and are suitable for detecting weight changes of people or items on the support plates.

[0006] The display unit is equipped with an input device and a display, and the input device and the display are electrically connected.

[0007] The timing module is configured to acquire the weighing time point of the weight change data fed back by the detection component;

[0008] The system includes a storage cloud server, which is communicatively connected to the detection device and the timing module. The storage cloud server is configured to store the weight change data fed back by the detection device and the weighing time node that stores the weight change data fed back by the detection device. The storage cloud server is also communicatively connected to the display unit.

[0009] When the user triggers the input device, the display unit displays the weight change data at a specified time point; when the user does not trigger the input device, the display unit displays the weight data at the current time point.

[0010] Beneficial effects: During the warehouse entry and exit phase, the support plate supports the items on it. When the load is stable for a set time, the detection device detects the weight change data of the items on the support plate. The timing module obtains the weighing time point of the weight change data fed back by the detection device, and the weight change data and weighing time point are fed back to the cloud storage server for storage. Users can accurately and in real time know the changes in the amount of items stored and retrieved and the time point of the storage and retrieval through the display screen, which is convenient for users to calculate the internal inventory of the warehouse and reduce the difficulty of warehouse management and supervision. This application is particularly suitable for use with liquids and irregular items that are difficult to count.

[0011] In one optional embodiment, the weighing system further includes a control unit electrically connected to the detection element, electrically connected to the timing module, and communicatively connected to the storage cloud server.

[0012] Beneficial effects: The control unit is used to convert the analog signal generated by the detection device into a digital signal, and transmit the digital signal to the cloud storage server for storage; the control unit triggers the timing module to respond to the feedback analog signal based on the weight change data fed back by the detection device, so as to obtain the digital signal corresponding to the time node of the weight change data, and transmit the digital signal to the cloud storage server for storage.

[0013] In one optional implementation, the weighing system further includes a counting module electrically connected to the control unit. The counting module contains weight data for a single item and is used to calculate the quantity of the items to feed back to the display unit and / or the cloud storage server.

[0014] Beneficial effects: The counting module is used to calculate the quantity of items. The control unit triggers the counting module to respond with a feedback analog signal based on the weight change data fed back by the detection device, so as to obtain a digital signal of the quantity of items corresponding to the weight change data of the items, and transmits the digital signal to the cloud server for storage. Of course, a signal connection path can be established between the counting module and the display unit to directly display the digital signal of the quantity of items on the display unit's screen, so as to achieve the purpose of weighing and displaying the quantity of items in real time.

[0015] In one optional embodiment, the bearing platform further includes a force transmission plate disposed between the bearing plate and the detection element, with one side of the force transmission plate fixedly connected to the bearing plate and the other side of the force transmission plate abutting against the detection end of the detection element.

[0016] In one alternative embodiment, the upper end face of the support plate is recessed to form a receiving cavity.

[0017] In one alternative implementation, the sensing element is configured as a resistance strain gauge sensor, a piezoelectric sensor, or an electromagnetic sensor.

[0018] In one alternative embodiment, the weighing system further includes a chassis having at least one loading position, the load-bearing platform being correspondingly disposed at the loading position, and the detection element being installed inside the chassis.

[0036] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] According to an embodiment of the present invention, a weighing system is provided, such as... Figures 1 to 3 As shown, the weighing system includes a chassis 1, a load-bearing platform 2, a display unit 3, a timing module 5, and a cloud storage server 6. The chassis 1 has one or more loading positions 101, and the load-bearing platform 2 is configured at the loading position 101. Each load-bearing platform 2 can be assembled through each loading position 101 on the chassis 1.

[0038] In this embodiment, as Figure 3 As shown, the support platform 2 includes a group of support plates 201 and detection elements 202. The support plates 201 and detection elements 202 are configured to transmit force. The detection elements 202 are installed inside the housing 1 and are located at the bottom of the support plates 201. The detection elements 202 are used to detect changes in the weight of personnel or items on the support plates 201. One detection element 202 is correspondingly installed at the bottom of each support plate 201.

[0039] In this embodiment, as Figure 4 As shown, display unit 3 is equipped with an input device and a display. The input device and display are electrically connected. The input device is used for user input of operation commands, and the display is used for displaying data. Timing module 5 is configured to acquire the weighing time point of the weight change data fed back by the detection element 202. Cloud storage server 6 is communicatively connected to detection element 202 and timing module 5. Cloud storage server 6 is configured to store the weight change data fed back by detection element 202 and the weighing time point of the weight change data fed back by detection element 202. Cloud storage server 6 is electrically connected to display unit 3.

[0040] The weighing system provided in this embodiment displays weight change data at a specified time point on the display unit 3 when the user triggers the input device; and displays weight data at the current time point on the display unit 3 when the user does not trigger the input device.

[0041] The weighing system provided in this embodiment supports the items on the support plate 201 during the warehouse entry and exit phase. When the load is stable for a set time, the detection element 202 detects the weight change data of the personnel or items on the support plate 201. At the same time, the timing module 5 obtains the weighing time node of the weight change data fed back by the detection element 202, and feeds back the weight change data and the weighing time node to the cloud storage server 6 for storage. Users can accurately and in real time know the change in the amount of items stored and retrieved and the time point of storage and retrieval through the display screen, which is convenient for users to calculate the internal inventory of the warehouse and reduce the difficulty of warehouse management and supervision. This application is particularly suitable for use with liquids and irregular items that are inconvenient to count.

[0042] The weighing system provided in this embodiment allows users to input operation commands through the input device in the display unit 3, so that they can subsequently retrieve the associated weight change data and weighing time points. This makes it easy for users to know the changes in the amount of items stored and retrieved and the time points when the storage and retrieval occurred through the display screen.

[0043] The time limit for ensuring stable load-bearing of an item can be set to 10 seconds, 15 seconds, 30 seconds, or 60 seconds, depending on the specific configuration.

[0044] In one optional embodiment, the upper end face of the support plate 201 is recessed to form a receiving cavity. The receiving cavity can accommodate liquids, irregular items, or other items that are difficult to count, which helps to stabilize the supported items more quickly and facilitates weighing and counting of the items.

[0045] In one alternative implementation, such as Figure 2 As shown, the weighing system also includes a control unit 4, which is electrically connected to the detection element 202, electrically connected to the timing module 5, and communicatively connected to the storage cloud server 6.

[0046] The weighing system provided in this embodiment includes a control unit 4 that converts the analog signal generated by the detection element 202 into a digital signal, which is then transmitted to the cloud storage server 6 for storage. The control unit 4 triggers the timing module 5 to respond to the analog signal based on the weight change data fed back by the detection element 202, thereby obtaining the digital signal corresponding to the time node of the weight change data and transmitting it to the cloud storage server 6 for storage. For example, the control unit 4 can convert the analog signals generated by the detection element 202 and the timing module 5 into digital signals using a built-in A / D converter.

[0047] In one alternative implementation, the timing module 5 may employ a timer, a DS1302 clock module, or the like.

[0048] In one alternative implementation, such as Figure 2As shown, the weighing system also includes a counting module 7, which is electrically connected to the control unit 4. The counting module 7 contains the weight data of a single item and is used to calculate the quantity of items to feed back to the display unit 3 and / or the cloud server 6.

[0049] The weighing system provided in this embodiment uses a counting module 7 to calculate the quantity of items. The control unit 4, based on the weight change data fed back by the detection element 202, triggers the counting module 7 to respond with a feedback analog signal to obtain a digital signal representing the quantity of items corresponding to the weight change data. This digital signal is then transmitted to the cloud storage server 6 for storage. In the subsequent retrieval phase, an operation command is input through the input device in the display unit 3 to retrieve the quantity of items online. Alternatively, a signal connection path can be established between the counting module 7 and the display unit 3 to directly display the digital signal representing the quantity of items on the display unit 3's screen, achieving real-time weighing and display of the quantity of items for convenient real-time user access.

[0050] In a specific implementation, the control unit 4 is configured as a Raspberry Pi. The Raspberry Pi can be installed inside the chassis 1. The Raspberry Pi has a processor, memory chip, power management chip, power supply port, network connection port, display port, at least three data ports, and the display port is connected to the display unit 3's monitor. The data ports are connected to the timing module 5, the storage cloud server 6, and the counting module 7.

[0051] In some optional implementations, the weighing system can be configured with a server and a user terminal. The server is used to access data on changes in the quantity of goods stored and retrieved, as well as the time points of these transactions, stored on the cloud server 6. The user terminal establishes a communication connection with the server and can input access commands to the server via an application to obtain the data on the quantity of goods stored and retrieved, as well as the time points of these transactions. Preferably, each time the data on the quantity of goods stored and retrieved, as well as the time points of these transactions, is stored on the cloud server 6, the server directly feeds it back to the user terminal, enabling the user to monitor the warehouse's management data, such as the quantity of goods stored and retrieved and the time points of these transactions, in real time through the user terminal's application.

[0052] In one optional embodiment, the detection element 202 is configured as a resistance strain gauge sensor, a piezoelectric sensor, or an electromagnetic sensor. A resistance strain gauge sensor offers a wide measurement range and high accuracy, making it suitable for weight monitoring of warehouse goods. A piezoelectric sensor provides high sensitivity, rapid response, high accuracy, and resistance to pressure and impact, making it suitable for dynamic measurements. An electromagnetic sensor offers high sensitivity, high accuracy, and good anti-interference capabilities.

[0053] In one alternative implementation, the input device is configured as at least one of a keyboard, mouse, and touchscreen. Of course, the input device can also be configured as an operation button.

[0054] In a specific implementation, operation commands can be input via a keyboard, and auxiliary input commands can be selected via a mouse. The keyboard and mouse are electrically connected to the control chip of the display unit 3 via A / D converters. The A / D converters convert the analog signals of the keyboard and mouse operation commands into digital signals recognizable by the cloud storage server 6, enabling the display unit 3 to access the cloud storage server 6 and display data such as the changes in the amount of items stored and retrieved, and the time of the storage / retrieval. In other implementations, operation commands can be input via a touchscreen to access and retrieve data such as the changes in the amount of items stored and retrieved, and the time of the storage / retrieval. It should be noted that the display unit 3 is equipped with a display; the user can select the input device according to actual needs to send read signals to the cloud storage server 6. The cloud storage server 6 then transmits the data to the display unit 3 for display. The user can adjust the input device as needed.

[0055] Of course, the control unit 4 can be connected to a configuration memory to directly store data such as changes in item access and the time when access occurred locally.

[0056] For the structural design implementation of chassis 1:

[0057] For example, in one alternative embodiment, the loading position 101 is configured as an assembly slot with a hollowed-out section inside the chassis 1, and the loading position 101 is arranged parallel to the length direction of the chassis 1.

[0058] For example, in one alternative implementation, such as Figure 1 As shown, the upper surface of the chassis 1 is provided with a partition 102, which is disposed between two adjacent loading positions 101. The partition 102 extends in a direction away from the upper surface of the chassis 1.

[0059] In a specific implementation, three loading positions 101 are provided, and two partitions 102 are provided, with the two partitions 102 respectively placed in two adjacent areas between the three loading positions 101.

[0060] For example, in one alternative implementation, such as Figure 1 As shown, a communication interface 103 is provided on the outer peripheral side wall of the chassis 1. The communication interface 103 is electrically connected to all the detection components 202, and the communication interface 103 is wired or wirelessly connected to the display unit 3.

[0061] When assembled and used, the chassis 1 can be placed on the external equipment rack, or the chassis 1 can be embedded in a groove in the ground to facilitate the weighing of personnel and goods.

[0062] In one alternative implementation, such as Figure 3 As shown, the bearing platform 2 also includes a force transmission plate 203, which is disposed between the bearing plate 201 and the detection piece 202. One side of the force transmission plate 203 is fixedly connected to the bearing plate 201, and the other side of the force transmission plate 203 abuts against the detection end of the detection piece 202. The force transmission plate 203 is used to transmit the gravitational force to the detection end of the detection piece 202.

[0063] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
