Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an intelligent device and a logistics asset management system. Background Art

[0002] Transport containers such as dry cargo containers, tank containers, IBC packaging barrels, etc. are the main carriers for cargo distribution, transportation, production and processing at this stage. They usually undergo long-term, long-distance, and multi-link transportation. During this process, the safety supervision of goods is a very important issue.

[0003] At present, during the distribution and transportation of transport containers, the items can generally be safely supervised through satellite positioning, base station positioning and other technologies. However, when the transport container enters the factory for production and processing, it is impossible to obtain the precise positioning of the transport container in the factory, resulting in the inability of the transport container to participate in production and processing management after entering the factory, such as the inability to accurately know the warehouse or workstation where the transport container is located. Moreover, if satellite positioning, base station positioning and other technologies are continued to be used to supervise the items after the transport container enters the factory, a large amount of approximate data of little value will be generated, and the energy storage power battery will be heavily loaded, resulting in a high cost.

[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application 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 application and are not used to limit the present application.

[0050] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0052] Transport containers such as dry cargo containers, tank containers, IBC packaging barrels, etc. are the main carriers for cargo distribution, transportation, production and processing at this stage. They usually undergo long-term, long-distance, and multi-link transportation. During this process, the safety supervision of goods is a very important issue.

[0053] At present, during the distribution and transportation of transport containers, the safety of items can generally be supervised through satellite positioning, base station positioning and other technologies. However, when the transport container enters the factory for production and processing, it is impossible to obtain the precise positioning of the transport container in the factory, resulting in the inability of the transport container to participate in production and processing management after entering the factory, such as the inability to accurately know the warehouse or workstation where the transport container is located. Moreover, if satellite positioning, base station positioning and other technologies are continued to be used to supervise items after the transport container enters the factory, a large amount of approximate data of little value will be generated, and the energy storage power battery will be heavily loaded, resulting in a high implementation cost. If a smart device is used for periodic uploads by wireless terminals outside the factory and uploads by wired terminals inside the factory, the difficulty of management will be greatly increased.

[0054] Based on this, the embodiment of the present application proposes an intelligent device and logistics asset management system. It is intended to install the intelligent device on the transport container, and through the design of the intelligent device, the positioning management of the transport container can be realized through the positioning module and the communication module during the distribution and transportation of the transport container. After the transport container enters the target area (such as a factory), the positioning module can be controlled to turn off, saving the power of the intelligent device and reducing costs; at the same time, the environmental information of the transport container (including the loaded items) in each processing step can be monitored through RFID electronic tags to achieve safe processing management. That is, in the distribution and transportation scenario, the positioning module is used to participate in in-transit management, and in the factory workshop scenario, the RFID electronic tags are used to accurately locate the process stations of the production process and participate in the production and processing process management.

[0055] Reference Figure 1 , Figure 1 is a first structural block diagram of the smart device provided in the embodiment of the present application. Figure 1 As shown, the smart device includes a microcontroller module 110, a communication module 120, a data acquisition module 130, a positioning module 140, an RFID electronic tag 150 and a radio frequency reading and writing module 160. Among them, the communication module 120, the data acquisition module 130, the positioning module 140 and the radio frequency reading and writing module 160 are all connected to the microcontroller module 110, and the RFID electronic tag 150 is connected to the radio frequency reading and writing module 160. Among them:

[0056] The positioning module 140 is used to collect the current location information of the smart device.

[0057] The communication module 120 is used to establish a communication connection with the data center platform to exchange data with the data center platform.

[0058] The data collection module 130 is used to collect the environmental information of the transport container.

[0059] The RFID electronic tag 150 is used to record the environmental information of the transport container and the positioning information of the smart device.

[0060] The radio frequency reading and writing module 160 is used to read the information recorded in the RFID electronic tag 150 and update the information recorded in the RFID electronic tag 150;

[0061] The microcontroller module 110 is used to:

[0062] When the smart device does not enter the target area, the control positioning module 140 works to obtain the current location information of the smart device and upload the location information to the data center platform. The target area includes an area where the transport container is stored for a preset time period and an area where the transport container is loaded and processed.

[0063] When it is detected that the smart device enters the target area, the positioning module 140 is controlled to be turned off, and when it is detected that the information recorded in the RFID electronic tag 150 changes, the radio frequency reading and writing module 160 is controlled to update the changed information in the RFID electronic tag 150 .

[0064] In the embodiment of the present application, the intelligent device is installed on a transport container such as a dry cargo container, a tank container, and an IBC packaging barrel. In the process of distributing and transporting items through the transport container, the monitoring information and location information collected by the intelligent device can be regularly recorded and updated through wireless data communication technology. Specifically, by setting a positioning module 140 and a communication module 120 in the intelligent device, satellite positioning such as GPS, Beidou, or communication base station positioning technology can be used to obtain the location information of the transport container in the distribution and transportation links, and timely update the logistics information of the items loaded in the transport container. Among them, the positioning module 140 and the communication module 120 can be integrated into one chip, for example, the EC600U chip can be used. The EC600U chip has a location collection function and a communication function, and can collect the latitude and longitude information of the current location of the transport container, and then send it to the data center platform to locate the location of the transport container.

[0065] In the embodiment of the present application, the data acquisition module 130 mainly includes several sensors, such as temperature sensors, humidity sensors, pressure sensors, etc., which are used to detect the environmental information of the transport container. The type of sensor can be determined according to the type of items loaded in the transport container and the regulatory requirements. For example, if the items loaded in the transport container are food, excessively high temperatures may affect the food, so the type of sensor can be set as a temperature sensor to collect the temperature of the environment in which the transport container is located.

[0066] The data center platform can be a cargo supervision platform or a logistics information monitoring platform. After receiving the information (including location information, environmental information, etc.) sent through the communication module, the data center platform can record and save this information, or send this information to a third-party platform, such as various logistics sites, or merchants, or buyers and other cargo-related parties.

[0067] The RFID tag 150 is usually composed of a chip and an antenna. The chip stores the tag information, and the antenna is used to receive and send signals. When the RFID tag 150 passes through a reader (i.e., a radio frequency reader / writer), the reader emits radio waves, which are reflected by the RFID tag 150 and transmit the information to the reader. The reader can read and write the tag information, thereby achieving automatic identification and tracking.

[0068] The materials of the RFID electronic tag 150 mainly include polyester film, copper foil, conductive adhesive, etc. Among them, the polyester film has good flexibility and is suitable for tags of various shapes; the copper foil has good conductivity and corrosion resistance and is a key material for realizing high-frequency reading and writing of the RFID electronic tag 150; the conductive adhesive is used to connect the copper foil and the polyester film together to form a good conductive path.

[0069] When selecting materials for the RFID electronic tag 150, factors such as the conductivity, flexibility, and cost of the material need to be comprehensively considered. Generally speaking, materials with good conductivity can improve the read and write performance of the tag, but the cost is relatively high; materials with good flexibility are suitable for making tags with complex shapes, but the conductivity is poor. Therefore, when selecting materials, it is necessary to make a trade-off based on the specific application scenario.

[0070] In the embodiment of the present application, when the microcontroller module 110 detects that the smart device has entered the target area, such as entering the factory, dock, warehouse and other areas, it is considered that after the transport container enters the target area, it is either stored in the warehouse waiting to be used, or it enters the factory workshop to join the production and processing link. At this time, the location of the transport container can only be obtained in the target area through the positioning module 140, such as only the location of the transport container can be obtained in the factory, and the specific location of the transport container in the factory cannot be accurately obtained, such as the location or workstation of the transport container cannot be accurately obtained. That is, after the transport container enters the factory, the transport container cannot be accurately tracked. Based on this, the embodiment of the present application sets an RFID electronic tag 150 in the smart device, so that after the smart device enters the target area, the specific location of the transport container (including the loaded items) in the factory can be located and tracked by the RFID electronic tag 150. At the same time, the RFID electronic tag 150 can also write the environmental information of the transport container, that is, the microcontroller module 110 can obtain the environmental information collected by the data acquisition module 130, and then control the radio frequency reading and writing module 160 to write the environmental information into the RFID electronic tag 150, so as to monitor the environmental information of the transport container (including the loaded items) in each processing step through the RFID electronic tag 150, and realize safe processing management. For example, the temperature information, pressure information, humidity information, etc. of the transport container (including the loaded items) during the processing of the workshop assembly line can be detected, thereby realizing abnormal monitoring of the transport container (including the loaded items) during the processing.

[0071] In the embodiment of the present application, the microcontroller module 110 is connected to the communication module 120, the data acquisition module 130, the positioning module 140 and the radio frequency reading and writing module 160, and is used to control the communication module 120, the data acquisition module 130, the positioning module 140 and the radio frequency reading and writing module 160. Specifically, the microcontroller module 110 can control the data acquisition module 130 to collect the environmental information of the transport container in real time or periodically, and can control the positioning module 140 to collect the location information of the transport container in real time or periodically. After detecting that the data acquisition module 130 collects the environmental information of the transport container, the communication module 120 can be controlled to establish a wireless communication connection with the data center platform to upload the environmental information of the transport container to the data center platform. After detecting that the positioning module 140 collects the location information of the transport container, the microcontroller module 110 can control the communication module 120 to establish a wireless communication connection with the data center platform to upload the location information of the transport container to the data center platform. When receiving the environment information collection instruction and location information collection sent by the data center platform, the microcontroller module 110 controls the data collection module 130 to collect the environment information of the transport container and controls the positioning module 140 to collect the location information of the transport container, and feeds back the collected information to the data center platform. At the same time, the microcontroller module 110 can also pre-write a program to determine whether the data of the transport container is abnormal, so that when the microcontroller module 110 detects that the environment information collected by the data collection module 130 is abnormal, it can control the communication module 120 to establish a communication connection with the data center platform to upload the abnormal environment information and abnormal alarm information to the data platform center, so as to achieve safe management of the transport container. After detecting that the transport container enters the target area, the microcontroller module 110 can control the positioning module 140 to shut down, such as disconnecting the power supply to the positioning module 140 so that the positioning module 140 does not work, or sending a control signal to the positioning module 140 to put the positioning module 140 in a standby state. This can save power consumption and increase the service life of the reserve battery of the smart device. At the same time, after the transport container enters the target area, when it is detected that the information recorded in the RFID electronic tag 150 has changed, the radio frequency reading and writing module 160 can be controlled to update the information recorded in the RFID electronic tag 150, thereby realizing the positioning supervision and production and processing safety supervision of the transport container in the target area (such as the factory area).

[0072] It should be noted that in the embodiment of the present application, since the smart device is installed on the transport container, it is considered that the smart device is bound to the transport container, and the location information of the smart device is the location information of the transport container, and the environment information of the smart device is the environment information of the transport container. When the transport container is loaded with items, the location information of the smart device is the location information of the transport container, which is the location information of the items, and the environment information of the smart device is the environment information of the transport container, which is the environment information of the items.

[0073] In one embodiment of the present application, the RFID electronic tag 150 is also used to record the identity information of the smart device, information related to the items loaded in the transport container, and timestamp information.

[0074] In the embodiment of the present application, the RFID electronic tag 150 is also used to record the identity information of the smart device, so that the transport container (including the items loaded in the transport container) can be bound to the smart device one-to-one. For example, the ID number of a smart device is bound to a transport container, and is bound to the items in the transport container. The RFID electronic tag 150 is also used to record information related to the items loaded in the transport container, such as recording the type, name and quantity of the items loaded in the transport container, thereby realizing the supervision of the information flow of the transport container during production and processing. At the same time, the RFID electronic tag 150 is also used to record the corresponding timestamp information, so that various types of information can be corresponded to the corresponding recording time, and the information flow supervision of the transport container based on the timeline during production and processing can be realized.

[0075] In the embodiment of the present application, in addition to recording the environmental information of the transport container and the positioning information of the smart device, the RFID electronic tag 150 also records the identity information of the smart device, the information related to the items loaded in the transport container, and the timestamp information. Therefore, after the transport container enters the target area (such as the factory area), the RFID electronic tag 150 can participate in the production area management, such as process management and material management. Let the internal and external management achieve one item and one code, and the information recorded by the RFID electronic tag 150 can realize information distribution without account management, and achieve the synchronization of usage rights and information rights, which will not be limited to the authority and data security of factories of different customers, and can reduce the data management costs of all parties in the operation and improve the efficiency of Internet of Things data application. And the information recorded by the RFID electronic tag 150 has the real-time nature of data, which can realize the integration of materials and material information, break down information barriers, avoid the duplication of data platforms, and reduce management costs.

[0076] In one embodiment of the present application, referring to Figure 2 , Figure 2It is a flowchart of the steps of the microcontroller module provided in the embodiment of the present application to detect whether the smart device enters the target area, including but not limited to steps S210 to S230.

[0077] Step S210, obtaining the current location information of the smart device collected by the positioning module;

[0078] Step S220, determining whether the current location information of the smart device belongs to the target area;

[0079] Step S230: When the current location information of the smart device belongs to the target area, it is determined that the smart device has entered the target area; otherwise, it is determined that the smart device has not entered the target area.

[0080] In the embodiment of the present application, the microcontroller module 110 can obtain the current location information of the smart device collected by the positioning module 140, so as to directly determine whether the current location information of the smart device belongs to the target area according to the current location information of the smart device collected by the positioning module 140. Among them, the target area is pre-written in the microcontroller module 110, so that after obtaining the current location information of the smart device collected by the positioning module 140, the microcontroller module 110 can compare the current location information of the smart device with the target area, that is, determine whether the current location information of the smart device falls into the pre-written target area, thereby determining whether the smart device has entered the target area.

[0081] In the embodiment of the present application, the microcontroller module 110 can accurately and timely determine whether the smart device has entered the target area, so that the control of the positioning module 140 and the like can be switched in time with the switching of the scene in which the transport container is located.

[0082] In one embodiment of the present application, when the smart device does not enter the target area, the microcontroller module is used to:

[0083] The control positioning module 140 periodically collects the current location information of the smart device, and controls the communication module 120 to periodically upload the current location information of the smart device to the data center platform.

[0084] In the embodiment of the present application, when the smart device does not enter the target area, such as when the smart device does not enter the factory area, the microcontroller module 110 can control the positioning module 140 to periodically collect the current location information of the smart device, and control the communication module 120 to periodically upload the current location information of the smart device to the data center platform. In this way, the location supervision of the transport container in the distribution and transportation links can be realized, and the logistics information of the items loaded in the transport container can be updated in time.

[0085] In one embodiment of the present application, when the smart device does not enter the target area, the microcontroller module is further configured to:

[0086] Controlling the data collection module to periodically collect environmental information of the transport container;

[0087] Determine whether there is any abnormality in the environmental information;

[0088] When it is determined that the environmental information is abnormal, the control communication module sends the environmental information and alarm information indicating that the environmental information is abnormal to the data center platform.

[0089] In the embodiment of the present application, when the smart device does not enter the target area, such as when the smart device does not enter the factory area, the microcontroller module 110 can control the environmental information of the transport container to be periodically collected by the data acquisition module 130, and detect whether the environmental information is abnormal. Among them, the microcontroller module 110 can pre-write a program for judging whether the environmental information of the transport container is abnormal, so that the microcontroller module 110 can judge whether the environmental information is abnormal after obtaining the environmental information of the transport container. For example, the temperature threshold and the pressure threshold are written in the microcontroller module 110. When the temperature of the transport container obtained by the collection exceeds the temperature threshold, it can be judged that an abnormal state occurs. Or when the pressure of the transport container obtained by the collection exceeds the pressure threshold, it can be judged that an abnormal state occurs. After judging that the environmental information is abnormal, the microcontroller module 110 can control the communication module 120 to establish a communication connection with the data center platform, so that the environmental information and the alarm information indicating the abnormality of the environmental information can be uploaded to the data center platform, and the data center platform will be uniformly supervised and saved. In this way, the safe supervision of the transport container during the distribution and transportation process can be achieved.

[0090] In one embodiment of the present application, referring to Figure 3 , Figure 3 It is a flowchart of the steps executed by the microcontroller module when the smart device enters the target area provided by the embodiment of the present application, including but not limited to steps S310 to S330.

[0091] Step S310, obtaining the current location information of the smart device determined by the interaction between the RFID electronic tag and the radio frequency reader / writer set in the target area;

[0092] Step S320, determining whether the current positioning information is consistent with the last positioning information recorded by the RFID electronic tag;

[0093] Step S330: When the current positioning information is inconsistent with the last positioning information recorded in the RFID electronic tag, the radio frequency reading and writing module is controlled to update the last positioning information recorded in the RFID electronic tag to the current positioning information.

[0094] In an embodiment of the present application, a plurality of radio frequency reading and writing devices are provided in the target area (such as a factory area), including movable radio frequency reading and writing devices and fixed radio frequency reading and writing devices. For example, a fixed radio frequency reading and writing device is provided at the starting position of each assembly line in the factory workshop where each assembly line enters each different process, so that when the transport container flows through each assembly line and enters the starting position of each different process, the positioning information of the transport container in the factory area can be determined through the interaction between the RFID electronic tag 150 and the radio frequency reading and writing device. For another example, a radio frequency reading and writing device is installed on a forklift in the factory area, so that when the forklift is operating to transport the transport container, the positioning information of the transport container in the factory area can also be determined through the interaction between the RFID electronic tag 150 and the radio frequency reading and writing device. The determined positioning information can be written into the RFID electronic tag 150 by the microcontroller module 110 to control the radio frequency reading and writing module 160. After detecting that the smart device, i.e., the transport container, has entered the target area (such as a factory), the microcontroller module 110 can obtain the current location information of the smart device determined by the interaction between the RFID electronic tag 150 and the radio frequency reader / writer device set in the target area, and when it is determined that the current location information is inconsistent with the last location information recorded by the RFID electronic tag 150, the microcontroller module 110 controls the radio frequency reader / writer module 160 to update the last location information recorded by the RFID electronic tag 150 to the current location information. Thus, the specific location of the transport container after entering the target area (such as a factory area) can be updated, so that the location tracking of the transport container in the target area can be realized.

[0095] In one embodiment of the present application, referring to Figure 4 , Figure 4 It is another step flow chart provided by an embodiment of the present application when the smart device enters the target area and executed by the microcontroller module, including but not limited to steps S410 to S430.

[0096] Step S410, obtaining the current environment information of the transport container collected by the data collection module;

[0097] Step S420, determining whether the current environment information is consistent with the previous environment information recorded by the RFID electronic tag;

[0098] Step S430: When the current environment information is inconsistent with the last environment information recorded by the RFID electronic tag, the radio frequency reading and writing module is controlled to update the last environment information recorded by the RFID electronic tag to the current environment information.

[0099] In the embodiment of the present application, after the intelligent device, that is, the transport container enters the target area (such as a factory), is detected, the data acquisition module 130 will continue to collect the current environmental information of the transport container in real time or periodically. Similarly, the microcontroller module 110 can pre-write a program to determine whether there is an abnormality in the environmental information of the transport container, so that the microcontroller module 110 can determine whether there is an abnormality in the environmental information after obtaining the environmental information of the transport container. For example, the temperature threshold and the pressure threshold are written in the microcontroller module 110. When the temperature of the transport container obtained by the collection exceeds the temperature threshold, it can be determined that an abnormal state occurs. Or when the pressure of the transport container obtained by the collection exceeds the pressure threshold, it can be determined that an abnormal state occurs. After determining that the environmental information is abnormal, the microcontroller module 110 can control the communication module 120 to establish a communication connection with the data supervision system in the target area, so that the environmental information and the alarm information representing the abnormality of the environmental information can be uploaded to the data supervision system in the target area, and the data supervision system in the target area will be uniformly supervised and saved. In this way, the safe supervision of the transport container during the production and processing process can be achieved.

[0101] In the embodiment of the present application, after the alarm module 170 is added, the microcontroller module 110 can also be used to control the alarm module 170 to issue an alarm when an abnormality is detected in the current environmental information.

[0102] In the embodiment of the present application, regardless of whether the transport container enters the target area (such as the factory area), the data acquisition module 130 will collect the environmental information of the transport container in real time or periodically. Therefore, after the microcontroller module 110 collects the current environmental information of the transport container, the microcontroller module 110 will detect whether there is an abnormality in the current environmental information, and when the abnormality is detected in the current environmental information, the alarm module 170 will be controlled to issue an alarm.
