Description

Technical Field

[0001] The present invention relates to the field of warehousing and logistics vehicles, and specifically to an aluminum pallet that can sense the usage status. The pallet has an embedded intelligent module that integrates a variety of sensors and mobile communication chips to sense changes in the usage status of the pallet in real time, identify whether the pallet is in an idle state, and periodically obtain the location information and other environmental information of the pallet, and use this information to achieve effective management of the pallet circulation turnover. Background Art

[0002] Pallet is the most basic unitized platform device in modern logistics system. It gathers scattered goods into cargo units with uniform specifications and consistent standards, which is convenient for mechanized operations of loading and unloading, warehousing management and transportation and distribution. It is a key basic equipment in the modern logistics industry and plays an important role in improving logistics efficiency and reducing costs.

[0003] Since the manufacturing cost of pallets is high and the demand is particularly huge, and the production of wooden pallets also consumes forest resources, it is natural to hope that pallets can be used throughout the entire logistics process and can be recycled many times. As a result, the pallet circulation sharing system has emerged. The pallet circulation sharing system realizes efficient logistics and effective circulation of resources, and can ensure the circulation and sharing of pallets in a certain region or nationwide. Its core includes physical networks distributed in the region or the country, computer information networks, pallet asset pools and professional operation teams. The pallet circulation sharing system uses a number of technologies including item coding technology, RFID electronic tags, GPS satellite positioning system, GIS geographic information system, computer information management system, etc.

[0004] Pallets circulating in the pallet circulation sharing system must be coded before they can be managed. Furthermore, the newly emerged "smart pallets" have added RFID electronic tags, which manage the receipt, delivery, entry and exit of pallets through manual code reading or automatic code reading by readers and writers. If the coding information of the goods carried by the pallet is bound to the pallet code through a computer information management system, the logistics process of the goods can also be tracked through pallet coding management. This is the so-called visualization of the logistics process. Some "smart pallets" have also added GPS satellite positioning technology, so that the location and transportation route of the pallet can be known.

[0005] The use of pallets and the emergence of pallet circulation and sharing systems have greatly improved logistics efficiency and reduced logistics costs for logistics demanders in many aspects. It is a trend and direction for the development and progress of the logistics industry.

[0006] In my country, the total number of pallets in the society is about 1.2 billion (2017), of which nearly 80% are wooden pallets. Standard pallets account for about 25%, which is much lower than 70% in the EU and 55% in the United States. However, thanks to the support of national policies, the growth rate of standard pallets is very fast. In 2016, the output of standard pallets was close to 40% of the total output of all pallets. The standardization of pallets is a prerequisite for the circulation and sharing of pallets. In addition, the rental volume of standard pallets in 2016 was close to 20 million, an increase of about 30% over the previous year. However, compared with the total number of pallets in the society, it is still very low. So far, there are only a handful of domestic companies engaged in pallet rental.

[0007] The reality reflected by the above data is that most pallets (including rented pallets) are currently circulating within the enterprise and rarely leave the enterprise. In other words, most companies have not yet achieved full-process pallet transportation. Some companies that use full-process pallet transportation use disposable pallets. From a global perspective, the current efficiency of pallet use in my country is very low, and an open pallet circulation and sharing system has not yet been formed. The survey found that there are many reasons why companies do not use full-process pallet transportation and use disposable pallets, including the lack of standardization of pallets, the contradiction between loading rate and loading and unloading efficiency, etc. The most important reason is that the turnover and recycling management of pallets is difficult. For companies engaged in pallet leasing, there are also problems such as low pallet turnover rate, high loss rate and damage rate, which result in increased capital investment and operating costs. Due to the lack of credit guarantee and monitoring system for cross-enterprise pallet circulation and sharing, pallet leasing companies find it difficult to obtain key information such as where the rented pallets are, who is using them, and whether they are vacant, which reduces the circulation efficiency of pallets and increases circulation costs. A complete logistics process may go through many links and last a long time. Only by timely grasping the location information of the pallet and knowing whether the pallet is still loaded with goods or is idle, can the pallet operator accurately and efficiently plan the recovery and scheduling of the pallet based on this information.

[0008] Traditional pallets have no identification mechanism and cannot carry logistics information, which makes the supervision of pallets more difficult. Under such circumstances, the risk of open pallet recycling is undoubtedly quite large. Therefore, the management of pallets has been improved through item coding technology, and RFID electronic tags have been further used for management. These measures can better solve the problem of pallet identification.

[0009] Another important reason why pallets cannot be shared and recycled is that it is impossible to know the current location of the pallet. RFID electronic tags can solve this problem to a certain extent, that is, to track the pallet by reading the tag information at each logistics node. However, if the operation is not standardized, causing misoperation and omission, or the pallet does not reach the next logistics node, the tracking chain through the RFID electronic tag may be interrupted, thereby losing the pallet information. Another technical means that some companies are trying now is to install GPS on the pallet to obtain the geographical location information of the pallet. However, if the pallet is indoors, GPS may not work effectively. In addition, GPS consumes a lot of energy, which is not very practical for devices such as pallets that are not convenient for frequent energy supply.

[0010] Another important issue related to whether the circulation of pallets is efficient and smooth is how to know the current use status of the pallet and how to judge whether the pallet is empty and can be recycled. RFID electronic tags can help to know whether the pallet has entered the logistics destination warehouse, but the pallet may still be in the state of carrying goods after entering the warehouse, so it is inaccurate to judge based on the warehouse entry information. In order to obtain the status information of the pallet, the current common practice is to check it on site manually, which affects its efficiency and accuracy. Summary of the invention

[0069] In the above logistics process, the pallet performs LBS positioning operations multiple times a day to determine the current position, and sends the acquired position information to the remote server.

[0070] According to the application, a smart aluminum tray capable of sensing the usage status, the smart module is composed of an integrated circuit component and a lithium battery. The integrated circuit component includes:

[0071] -Microprocessor, used to execute various operation instructions;

[0072] - Flash Memory, memory, used to store pallet coding data, pallet status data, monitoring data, location information data, etc.;

[0078] According to the present application, a smart aluminum pallet capable of sensing the usage status is set as follows:

[0079] 1) Place a permanent magnet sheet with a cross-sectional size similar to that of the pier foot between the bottom plate and the anti-slip foot pad below the central pier foot of the tray;

[0080] 2) Place the intelligent module box in the central pier foot;

[0081] 3) The intelligent module box is designed as a square box with built-in integrated circuit board and lithium battery. The outer shell is made of engineering plastic and sealed;

[0082] 4) The Hall sensor is fixed on the top of the smart module box and is not attached to the integrated circuit board. Multiple Hall sensors can be arranged as needed. The Hall sensor is connected to the integrated circuit board through wires;

[0083] 5) The temperature and humidity sensor is led out of the smart module box through a wire and placed at the top of the outside of the smart module box, close to the upper bridge board of the pier foot;

[0084] 6) Screw holes are opened on both sides of the smart module box for fixing the smart module box and the pier feet with bolts. Inside the smart module box, the screw holes are connected to the signal input / output pins of the mobile communication chip on the integrated circuit board. Through this design, the pier feet are used as the external communication antenna of the smart module to avoid the aluminum material of the pier feet from shielding the wireless signal.

[0085] According to the present application, a complete method for using a smart aluminum pallet that can sense the usage status includes the following steps:

[0086] 1) After the new pallet is placed, the intelligent module is started through remote command operation;

[0087] 2) Through a specific procedure, the pallet code is bound to the smart chip identification code.

[0088] 3) The default status of the pallet when it leaves the factory is "in use". After the intelligent module is started, the management system determines whether the pallet is idle by sensing whether there are other pallets in close proximity and marks the status of the pallet in the system;

[0089] 4) The pallet then performs an LBS positioning operation and sends the acquired location information to the remote server;

[0090] 5) After completing the above two tasks, the intelligent module enters sleep mode;

[0091] 6) The pallet is sent from the operation center to the user for use. When sending it out, the manager uses a specific device to scan the pallet code, or the pallet passes through a fixed code reader during transportation to complete the pallet sending operation;

[0092] 7) When the pallet arrives at the user's site and is ready to be loaded, the pallet user's staff scans the code to enter the warehouse;

[0093] 8) The pallet senses the change in stacking status and sends a corresponding signal, and the system platform re-marks the pallet status;

[0094] 9) After the pallet is loaded, the user will carry out the outbound operation;

[0095] 10) After arriving at the logistics destination, the consignee performs warehousing and unloading operations;

[0096] 11) After unloading, the pallet is stacked and the system platform immediately changes the status mark of the pallet;

[0097] 12) During the above logistics process, the current position of the pallet is determined multiple times a day;

[0098] 13) The pallet operation management system summarizes and compiles data on pallets in various states at each location, and dispatches them according to the pallet demand and demand schedule in each region. Idle pallets may be put into use at the original location to continue carrying goods, or transported to another location for use, or transported to the operation center for maintenance.

[0099] 14) After maintenance, the pallets entering the operation center enter the next logistics cycle again.

[0100] According to the application of the intelligent aluminum pallet capable of sensing the usage status, the various functions and technical implementation methods of the present invention are as follows:

[0101] 1) Bind the smart chip identification code (ID) to the traditional pallet code (such as barcode, QR code, etc.). At each node of the pallet flow, the pallet is still managed by scanning the code, and the information read by the scan code enters the management platform database. During the in-transit process between each node, the smart chip ID is used instead of the pallet code to realize the monitoring and management of the pallet. The mobile communication module built into the smart module is located through the LBS mobile base station, and sends the current location information of the pallet and the smart chip ID to the remote platform several times a day. The frequency of daily communication with the remote platform can be set and adjusted on the platform server.

[0102] 2) In actual application scenarios, when the pallets are empty, they will be stacked neatly. At this time, for the two adjacent pallets, the distance between the Hall sensor in the lower pallet and the magnetic sheet in the upper pallet must be very close, usually less than 10 cm, such as Figure 4 As shown in the figure: As the magnetic sheet in the upper pallet is close to the Hall sensor in the lower pallet, the Hall sensor senses the presence of the nearby magnetic field and outputs a switch signal in real time. After the relevant information is transmitted to the remote platform, the platform will mark the pallet with the built-in Hall sensor as being empty. On the contrary, when the stacked pallets are removed and prepared for loading, as the magnetic sheet in the upper adjacent pallet moves away, the Hall sensor in the lower pallet will send out the opposite switch signal. After receiving the signal, the remote platform will mark the status of this pallet as "in use" until the pallet is stacked again and then re-mark the status.

[0103] 3) The temperature and humidity sensor in the intelligent module measures the temperature and humidity of the environment where the pallet is located on a daily basis, and sends it to the remote platform along with the geographic location information on a daily basis.

[0104] According to the present application, a smart aluminum pallet that can sense the usage status is redesigned and intelligently transformed from an ordinary pallet, combined with the application of the Hall effect principle, mobile communication technology, LBS service and GIS geographic information system, etc., to effectively solve the following problems existing in the recycling of pallets: 1) Pallet coding management and logistics process tracking; 2) Determination of the current position of the pallet; 3) Determination of the current usage status of the pallet, by determining whether the pallet has been idle through the presence or absence of a close-range sensing magnetic field by the Hall sensor.

[0105] According to the present application, a smart aluminum pallet that can sense the use status is applicable to aluminum pallets. Compared with pallets made of other materials, aluminum pallets have the following advantages: 1) high strength; 2) easy to clean and maintain; 3) little change in appearance after long-term use; 4) light weight; 5) the specification structure can be designed and customized according to needs; 6) the carrying capacity is suitable for light and heavy goods; 7) the product residual value is high. Therefore, aluminum pallets are more conducive to long-term recycling.

[0106] According to the application, a smart aluminum pallet capable of sensing the usage status has the beneficial effect of:

[0107] 1) Different from other "smart pallets" that use GPS positioning, this uses LBS mobile communication base station positioning to meet the needs of indoor positioning while reducing power consumption;

[0108] 2) Through the mobile communication module, the pallet can be connected to the Internet and conduct two-way communication with the remote server;

[0109] 3) The intelligent module is sealed inside the pallet and powered by a long-lasting lithium battery, which reduces the maintenance cost of the intelligent pallet;

[0110] 4) The wireless communication antenna of the intelligent module is led out to the external pier, which effectively overcomes the shielding of the wireless communication signal by aluminum;

[0111] 5) By binding the pallet code with the smart chip identification code, the pallet's control range is extended to the entire logistics process;

[0112] 6) Through the cooperation of the Hall sensor and the permanent magnet sheet, the change of the tray's usage status can be sensed in real time. It has a compact structure, is stable and safe, has low power consumption, and can be accurately and reliably identified.
