Description

Technical Field

[0001] The embodiments of the present invention relate to the field of logistics technology, and specifically to a logistics information tracking method and system. Background Art

[0002] In intelligent logistics production lines, RFID (Radio Frequency Identification) systems are often used to track logistics information. By reading and writing data on RFID tags attached to products, companies can accurately monitor and manage the status, location, and quantity of products on the logistics line.

[0003] At present, the traditional RFID system consists of a reader / writer, an electronic tag and an RFID controller. The electronic tag is a transceiver with a wireless antenna and a readable and writable chip inside. The reader / writer can read the data in the chip of the electronic tag, and can also write data to the chip of the electronic tag through the instructions of the RFID controller. At the same time, the RFID controller communicates with the relevant host computer to realize centralized control and perform relevant application processing on the data.

[0004] However, the reader / writer of the RFID system generates radio frequency signals when reading and writing data in the chip of the electronic tag. The energy generated by the radio frequency signal cannot meet the minimum energy standard of intrinsic safety explosion-proof certification, which will cause the RFID system to fail to achieve intrinsic safety explosion-proof certification and achieve certification in the form of flameproof. This makes the RFID system unable to be used in explosion-hazardous environments with electrical intrinsic safety requirements. During the installation and implementation process, the cables of the relevant electrical systems cannot be laid without protection like the intrinsic safety system, but must be protected by explosion-proof products, resulting in additional cost expenditure. At the same time, the application and processing of RFID system data must be implemented using independent supporting software, which requires maintenance personnel to conduct additional learning and training on the supporting software of the RFID system in addition to maintaining the main equipment system of the production line. Therefore, the RFID system has problems such as a narrow application range, cumbersome installation, high cost of use, and extra maintenance effort in logistics production lines in explosion-hazardous environments.

[0067] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0069] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0070] The word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if determining" or "if monitoring (stated condition or event)" may be interpreted as "when determining" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0071] The radio frequency signals generated by the reader / writer of the traditional RFID system when reading and writing the data in the chip of the electronic tag will cause the RFID system to fail to achieve intrinsic safety explosion-proof certification, and it must be certified in the form of explosion-proof. This makes it impossible for the RFID system to be used in explosion-hazardous environments with electrical intrinsic safety requirements. During the installation and implementation process, the cables of the relevant electrical system cannot be laid without protection like the intrinsic safety system, but must be protected by explosion-proof products, resulting in additional cost expenditure. At the same time, the application and processing of RFID system data must be implemented using independent supporting software, which requires maintenance personnel to carry out additional learning and training on the supporting software of the RFID system in addition to maintaining the main equipment system of the production line. Therefore, the RFID system has problems such as a narrow application range, cumbersome installation, high cost of use, and extra maintenance effort in logistics production lines in explosion-hazardous environments.

[0072] In view of this, the embodiment of the present invention provides a new idea. In order to facilitate the understanding of the present application, the system architecture based on the embodiment of the present invention is first described. Figure 1 An exemplary system architecture to which the present invention can be applied is shown. Figure 1 As shown in , the system architecture may include a terminal device and a logistics information tracking device located on the server side.

[0073] The terminal devices may include, but are not limited to, smart mobile terminals, smart home devices, wearable devices, PCs (Personal Computers), etc. Smart mobile terminals may include mobile phones, tablet computers, laptop computers, PDAs (Personal Digital Assistants), Internet cars, etc. Smart home devices may include smart TVs, smart refrigerators, etc. Wearable devices may include smart watches, smart glasses, virtual reality devices, augmented reality devices, mixed reality devices (i.e., devices that can support virtual reality and augmented reality), etc.

[0074] The logistics information tracking device can use the logistics information tracking method provided in the embodiment of the present invention to track logistics information.

[0075] The above-mentioned logistics information tracking device can be set up in a single server, in a server group consisting of multiple servers, or in a cloud server. A cloud server, also known as a cloud computing server or cloud host, is a host product in the cloud computing service system to solve the defects of difficult management and weak service scalability in traditional physical hosts and virtual private servers (VPS). Figure 1In addition to the shown architecture, the logistics information tracking device can also be set on a computer terminal with strong computing power.

[0076] Figure 2 A flow chart of a logistics information tracking method provided by an embodiment of the present invention, the method can be Figure 1 The logistics information tracking device in the system shown is executed. Figure 2 As shown in , the method may include the following steps:

[0077] Step 201: Obtain a target address in the first logistics information table corresponding to the current workstation, where the target address in the first logistics information table is the address of the designated workstation to which the first box is to be transferred on the logistics production line.

[0078] Step 202: Determine whether the target address in the first logistics information table is the address of the current workstation where the first box is located.

[0079] Step 203: If not, a first conveying instruction is sent to a first conveying device at the current workstation, where the first conveying instruction is used to instruct the first box to be conveyed to the next workstation.

[0080] Step 204: Update the information of the second box in the second logistics information table corresponding to the next workstation to the information of the first box in the first logistics information table, and delete the information of the first box in the first logistics information table.

[0081] Step 205, determining whether the target address in the second logistics information table is the address of the next workstation where the first box is located.

[0082] Step 206, if yes, determine that the first box is transferred to the designated workstation of the logistics production line; otherwise, jump to the previous step 202.

[0083] It can be seen from the above process that the cables of the relevant electrical system in the embodiment of the present invention can be laid without protection like the intrinsically safe system during the installation and implementation process, without the need for additional explosion-proof products for protection. Therefore, the installation is simple, no additional cost expenditure is required, and the cost is low. The embodiment of the present invention does not use the RFID system, and no additional learning and training is required for the supporting software of the RFID system, and no additional maintenance effort is required. At the same time, since the embodiment of the present invention does not need to use the RFID system, it can be applied to the logistics production line in the explosive hazardous environment. Therefore, the embodiment of the present invention has a wide range of applications.

[0084] The following is a detailed description of each step in the above process and the effects that can be further produced in conjunction with the embodiments of the present invention. It should be noted that the "first" and "second" and other limitations involved in the embodiments of the present invention do not have limitations in terms of size, order, and quantity, and are only used to distinguish them in name, for example, "first conveying device" and "second conveying device" are used to distinguish two different conveying devices.

[0085] First, the above step 201, i.e., "obtaining the target address in the first logistics information table corresponding to the current workstation, where the target address in the first logistics information table is the address of the designated workstation to which the first box is to be transferred on the logistics production line" is described in detail in combination with an embodiment of the present invention.

[0086] In an embodiment of the present invention, step 201 is implemented by the following steps: obtaining the warehousing arrangement target information of each box; assigning the warehousing arrangement target information of the first box to the target address in the first logistics information table corresponding to the current workstation.

[0087] It is understandable that each workstation has a corresponding logistics information table. The logistics information table stores the target address of the box. The logistics information table is stored in the register corresponding to the workstation. Exemplarily, the current workstation is workstation 1, and the logistics information table corresponding to it is the first logistics information table. The first logistics information table stores the target address 1 of the first box. The first logistics information table is stored in register 1 corresponding to workstation 1.

[0088] In one example, the target information of each box is obtained. The target information of the box is the target address of the designated station to be transferred to the logistics production line after the box is stored. The target information of the first box is assigned to the target address in the first logistics information table corresponding to the current station, so that the target address of the first box is stored in the first logistics information table. The target address is the address of the designated station to be transferred to the logistics production line by the first box.

[0089] In the embodiment of the present invention, it can be understood that obtaining the warehousing arrangement target information of each box can be achieved through the following steps: obtaining target parameters, the target parameters including material production output parameters, warehousing location number parameters and warehousing box quantity parameters; determining the warehousing arrangement target information of each box according to the material production output parameters, warehousing location number parameters and warehousing box quantity parameters.

[0090] As a possible implementation method, the storage location number parameter and the storage box quantity parameter are determined according to the material production output parameter and the preset threshold. The target address of each box is generated according to the material production output parameter, the storage location number parameter and the storage box quantity parameter, which serves as the storage arrangement target information of each box.

[0091] In an example, if the material production output parameter is less than or equal to 5 tons, the boxes do not need to be stored. If the material production output parameter is greater than 5 tons and less than or equal to 7.5 tons, the boxes need to be stored (there are 4 storage locations and 4 boxes per storage). If the material production output parameter is greater than 7.5 tons and less than or equal to 10 tons, the boxes need to be stored (there are 8 storage locations and 4 boxes per storage). If the material production output parameter is greater than 10 tons and less than or equal to 12.5 tons, the boxes need to be stored (there are 8 storage locations and 4 boxes per storage). If the material production output parameter is greater than 12.5 tons and less than or equal to 15 tons, the boxes need to be stored (there are 8 storage locations and 6 boxes per storage). If the material production output parameter is greater than 15 tons and less than or equal to 20 tons, the boxes need to be stored (there are 16 storage locations and 4 boxes per storage). If the material production output parameter is greater than 20 tons and less than or equal to 25 tons, the boxes need to be stored (there are 16 storage locations and 5 boxes per storage). If the material production output parameter is higher than 25 tons and lower than or equal to 30 tons, the boxes need to be put into storage (there are 16 storage spaces, and each space has 6 boxes).

[0092] In an example, assuming that the material production output parameter is equal to 10 tons, the corresponding storage locations are 8, and the number of boxes in each storage location is 4. The 8 storage locations can be selected by the operator. If the operator selects storage location numbers 1 to 7 and 9 in the embodiment of the present invention, the target address of each box generated thereby is in the following format {1, 2, 3, 4, 5, 6, 7, 9, 1, 2, 3, 4, 5, 6, 7, 9, 1, 2, 3, 4, 5, 6, 7, 9, 1, 2, 3, 4, 5, 6, 7, 9}.

[0093] It can be understood that assigning the warehousing arrangement target information of the first box to the target address in the first logistics information table corresponding to the current workstation can be achieved through the following steps: obtaining a first indication instruction, wherein the first indication instruction is used to indicate that the first box is already located at the current workstation of the logistics production line; assigning the warehousing arrangement target information of the first box to the target address in the first logistics information table corresponding to the current workstation.

[0094] It should be noted that an intrinsically safe level sensor is installed at the exit of the logistics path of each workstation to provide feedback on whether there are boxes staying at each workstation on the logistics production line. It is connected to the logistics information tracking device (i.e. Figure 5 and / or Figure 7 When the intrinsically safe level sensor detects that a box has stopped at a workstation, it will send an instruction to the logistics information tracking device. After the logistics information tracking device obtains the instruction, it will assign the storage arrangement target information of the aforementioned box to the target address in the logistics information table corresponding to the aforementioned workstation.

[0095] In one example, an intrinsically safe level sensor 1 is provided at the exit of the logistics path of the current workstation, i.e., workstation 1. When the intrinsically safe level sensor 1 detects that a first box has stopped at workstation 1, it sends a first instruction to the logistics information tracking device. After the logistics information tracking device obtains the first instruction, it assigns the storage arrangement target information of the first box to the target address in the first logistics information table corresponding to the current workstation.

[0096] The above step 202, i.e., "determining whether the target address in the first logistics information table is the address of the current workstation where the first box is located" is described in detail below in conjunction with an embodiment of the present invention.

[0097] In the embodiment of the present invention, if the target address in the first logistics information table is the address of the current station where the first box is located, it is determined that the first box has been transferred to the designated station of the logistics production line. If the target address in the first logistics information table is not the address of the current station where the first box is located, go to step 203.

[0098] The above step 203, i.e., "if not, sending a first conveying instruction to the first conveying device of the current workstation, wherein the first conveying instruction is used to instruct to convey the first box to the next workstation", is described in detail below in conjunction with an embodiment of the present invention.

[0099] In the embodiment of the present invention, the first conveying instruction includes: a second starting instruction.

[0100] As a possible implementation, step 203 can be implemented as follows: Figure 3 The steps shown achieve:

[0101] Step 301: If not, a first start instruction is sent to the second conveying device of the next station, where the first start instruction is used to instruct to start the second conveying device.

[0102] In the embodiment of the present invention, if the target address in the first logistics information table is not the address of the current station where the first box is located, it is determined whether there is a second box at the next station. If there is a second box, the first conveying device at the current station waits for delivery. Figure 4 As shown, if there is no second box at the next station, it is determined whether there is still information about the second box in the second logistics information table. If there is information about the second box, it means that the second box is being transported. If there is no information about the second box in the second logistics information table (the intrinsically safe level sensor is used to determine whether there is a second box at the next station, that is, station 3, and if so, Figure 4As shown, it is determined to delete the information of the second box in the second logistics information table), and then a descending instruction is sent to the first blocking device of the current station, so that the first blocking device descends to the first preset position. Then, a first start instruction is sent to the second conveying device of the next station to start the second conveying device to start conveying.

[0103] Step 302: Receive a first feedback signal fed back by a second conveying device, where the first feedback signal is used to indicate that the second conveying device has started conveying.

[0104] In the embodiment of the present invention, after the second conveying device starts conveying, it feeds back a first feedback signal to the logistics information tracking device. The logistics information tracking device receives the first feedback signal fed back by the second conveying device to determine that the second conveying device has started conveying.

[0105] Step 303: Send a second start instruction to the first conveying device of the current workstation according to the first feedback signal, where the second start instruction is used to instruct to start the first conveying device.

[0106] In the embodiment of the present invention, after receiving the first feedback signal fed back by the second conveying device, a second start instruction is sent to the first conveying device at the current workstation to start the first conveying device to start conveying.

[0107] Step 304: Receive a second feedback signal fed back by the first conveying device, where the second feedback signal is used to indicate that the first conveying device has started conveying.

[0108] In the embodiment of the present invention, after the first conveying device starts conveying, it feeds back a second feedback signal to the logistics information tracking device. The logistics information tracking device receives the second feedback signal fed back by the first conveying device to determine that the first conveying device has started conveying.

[0109] Step 305: Receive a second indication instruction, where the second indication instruction is used to indicate that the first box has arrived at the next workstation.

[0110] In the embodiment of the present invention, an intrinsically safe level sensor 2 is provided at the exit of the logistics path of the next station (i.e., station 2). When the intrinsically safe level sensor 2 detects that the first box has stopped at station 2, it sends a second indication instruction to the logistics information tracking device. After the logistics information tracking device obtains the second indication instruction, it determines that the first box has arrived at the next station.

[0111] The above step 204, i.e., "updating the information of the second box in the second logistics information table corresponding to the next workstation to the information of the first box in the first logistics information table, and deleting the information of the first box in the first logistics information table" is described in detail below in conjunction with an embodiment of the present invention.

[0112] In an embodiment of the present invention, when the intrinsically safe level sensor 2 detects that a first box is staying at the workstation 2 in step 203, the information of the second box in the second logistics information table corresponding to the next workstation is updated to the information of the first box in the first logistics information table, and the information of the first box in the first logistics information table is deleted.

[0113] The above step 205, namely "determining whether the target address in the second logistics information table is the address of the next workstation where the first box is located", is described in detail below in conjunction with an embodiment of the present invention.

[0114] In an embodiment of the present invention, when the information of the second box in the second logistics information table corresponding to the next workstation is updated to the information of the first box in the first logistics information table, it is determined whether the target address in the second logistics information table is the address of the next workstation where the first box is located.

[0115] The above step 206, namely "if yes, determine that the first box is transferred to the designated position of the logistics production line; otherwise, jump to the previous step 203" is described in detail below in conjunction with an embodiment of the present invention.

[0116] In the embodiment of the present invention, if the target address in the second logistics information table is the address of the next station where the first box is located, it is determined that the first box is transferred to the designated location of the logistics production line. If the target address in the second logistics information table is not the address of the next station where the first box is located, jump to the previous step 203.

[0117] It can be seen from the above that the cables of the relevant electrical systems in the embodiments of the present invention can be laid unprotected like the intrinsically safe system during the installation and implementation process, without the need for additional explosion-proof products for protection. Therefore, the installation is simple, no additional cost is required, and the cost is low. The embodiments of the present invention do not use the RFID system, and no additional learning and training is required for the supporting software of the RFID system, and no additional maintenance effort is required. At the same time, since the embodiments of the present invention do not require the use of the RFID system, they can be applied to logistics production lines in explosion-hazardous environments. Therefore, the embodiments of the present invention have a wide range of applications. In addition, at the explosion-hazardous area, the position of the box is determined by using an intrinsically safe level sensor with high market maturity and low cost that has passed the intrinsically safe explosion-proof certification, and the same function as the radio frequency identification system is achieved through the algorithm deployed in the control system in the safe area, which overcomes the problem that the energy generated by the radio frequency signal of the existing manufacturers cannot be reduced to the minimum energy standard that meets the intrinsically safe explosion-proof certification.

[0118] Based on the same concept as the above method embodiment, the embodiment of the present invention also provides a logistics information tracking system. Figure 5 As shown, the logistics information tracking system includes: a control system 501 and a logistics transportation system 502.

[0119] Control system 501, used to obtain the target address in the first logistics information table corresponding to the current workstation;

[0120] Determine whether the value of the target address in the first logistics information table is the value of the address of the current workstation where the first box is currently located;

[0121] If not, sending a first conveying instruction to a first conveying device, wherein the first conveying instruction is used to instruct to convey the first box to a next station;

[0122] Update the information of the second box in the second logistics information table corresponding to the next workstation to the information of the first box in the first logistics information table, and delete the information of the first box in the first logistics information table;
