In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. Every other embodiment that can be obtained by a person skilled in the art without making creative efforts based on the embodiments of the present application falls within the protection scope of the present application.

According to research, at present, container loading and unloading events are recorded in a manual recording mode, such as the condition and time of container loading or unloading, however, the manual recording mode is not only prone to errors, but also low in efficiency, and wastes a large amount of human resources.

Based on this, the embodiment of the application provides a loading and unloading event generating system for a container based on the RFID technology, and the loading and unloading event generating system can automatically generate the loading and unloading event of the container by scanning the RFID tags on the container and the truck, and does not need to manually record, thereby improving the working efficiency.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a system for generating a loading and unloading event of a container according to an embodiment of the present disclosure. As shown in fig. 1, a loading and unloading event generating system 100 provided in the embodiment of the present application includes: RFID scanner 110, transmitter 120, and server 130.

The RFID scanner 110 is configured to scan at least one RFID tag disposed on a container and/or a truck, generate corresponding target information based on the scanned RFID tag, and transmit the target information to the transmitter.

It should be noted that, the RFID (Radio Frequency Identification) tag herein refers to an electronic tag, and the electronic tag is a non-contact automatic Identification technology, and identifies a target object and obtains related data through a Radio Frequency signal, and the Identification work does not require manual intervention, and as a wireless version of a barcode, the RFID technology has the advantages of water resistance, magnetism prevention, high temperature resistance, long service life, large reading distance, capability of encrypting data on the tag, larger storage data capacity, free change of stored information, and the like, which are not possessed by the barcode. According to embodiments provided herein, the RFID tag may be disposed on the container and/or the truck, and thus the RFID tag may include at least one of a container RFID tag and a truck RFID tag. Wherein, the container RFID tag refers to an RFID tag for identifying a container, and different container RFID tags are used for distinguishing different containers. Truck RFID tags refer to RFID tags used to identify trucks, and different truck RIFD tags are used to distinguish different trucks.

The target information may include tag information and RFID signals of the crane. The tag information of the crane refers to the corresponding related tag data of the crane, such as the code or license plate number of the crane, which is not specifically limited in this application, and since the RFID scanner 110 is installed on each crane, the RFID scanner 110 carries the corresponding tag information of the crane to distinguish different cranes. The RFID signal refers to an RFID signal generated based on the scanned RFID tag to distinguish which target object is identified by the RFID scanner 110, and the generated RFID signal further includes related data corresponding to the identified target object. According to embodiments provided herein, the RFID signal may include at least one of a container RFID signal and a truck RFID signal. The container RFID signal is used to represent that the RFID scanner 110 identifies that the container is a container, and the container RFID signal may further include related data such as a number or a name of the container, so as to distinguish different containers, which is not limited in this application. The truck RFID signal is used to characterize that the RFID scanner 110 identifies a truck, and the truck RFID signal may further include a number or a license plate number of the truck, which is used to distinguish different trucks, and this application is not limited in this respect.

As an alternative implementation, according to the embodiment provided in the present application, the RFID scanner 110 is installed on the crane, and particularly, may be installed right in front of the front crane, so that the RFID scanner 110 can scan the RFID tag more clearly when the crane is loading or unloading the container. One container can be provided with two identical container RFID tags which can be respectively arranged on two sides of the container. A truck can be provided with two identical truck RFID tags which can be respectively arranged on two sides of the truck. Thus, when the front crane performs container handling operations on the side of the truck, the RFID scanner 110 on the crane can scan the RFID tag on the side of the truck or on the side of the container. The RFID scanner 110 scans RFID tags at a frequency per second, generates corresponding target information based on the scanned RFID tags after at least one RFID tag is scanned, and transmits the target information to the transmitter 120 at the frequency per second.

The transmitter 120 is configured to transmit the received target information to the server 130.

In accordance with the embodiment provided herein, in implementation, the transmitter 120 transmits the received target information to the server 130 at a frequency per second after receiving the target information transmitted by the RFID scanner 110. As an alternative, the transmitter 120 is connected to the RFID scanner 110, and may be selected from the product E-Rooter of G7 (internet of things).

As an alternative implementation, two transmitters 120 may be placed on the crane, one is used as a host and the other is used as a standby, and when the signal of the transmitter 120 of the host is poor, the transmitter 120 of the standby may be switched to perform signal transmission, so that it may be ensured that the target information received by the server 130 is not interfered by the network state, the received signal is more accurate, and further, the server 130 may more accurately determine the loading and unloading event of the container.

Here, it should be noted that the above examples of the type of the generator 120 are merely examples, and in practice, the type of the generator 120 is not limited to the above examples.

The server 130 is configured to generate a loading and unloading event of the container based on the received target information.

Wherein the loading and unloading event comprises any one of a boxing event, a unpacking event and a box moving event.

It should be noted that the loading event refers to a process in which the crane loads the container onto the truck. An unloading event refers to the process of a crane unloading a container from a truck. A transfer event refers to the process of a crane moving a container from one truck to another truck.

As an alternative implementation, the target information collected by the server 130 is stored in the open source tool Kafka, specifically, Kafka is an open source stream processing platform developed by Apache software foundation, and is written by Scala and Java, and is a high throughput distributed publish-subscribe messaging system, which can process all action stream data platforms of the consumer in the website, and is equivalent to a processor, and analyzes the received signal.

According to the embodiment provided in the present application, in implementation, the server 130 analyzes the target information after receiving the target information transmitted by the transmitter 120, and generates a loading and unloading event of the container based on the received target information.

As an alternative embodiment, the server 130 generates a loading and unloading event of the container based on the received target information by:

when the target information includes the received tag information of the crane and the RFID signal of the container, the number of occurrences of the tag information of the crane and the RFID signal of the container in common is determined.

The target information refers to a signal received by the server 130 and transmitted by the transmitter 120. The first preset number refers to a number of occurrences of a signal preset in advance and used for determining whether an event starts, for example, the first preset number may be preset to 3 times, which is not specifically limited in this application.

According to the embodiment provided in the present application, when the crane is used to perform a container loading operation on a container, it is first required to lift the container from another place, and the RFID scanner 110 on the crane scans the RFID tag of the container mounted on the container and generates an RFID signal of the container, and transmits the generated RFID signal of the container and the tag information of the crane to the transmitter 120 as target information, and the transmitter 120 transmits the target information to the server 130 so that the server 130 can analyze the target information. When the server 130 receives the target information including the tag information of the crane and the RFID signal of the container, it determines the number of times of the common occurrence of the tag information of the crane and the RFID signal of the container, and when the number of times of the common occurrence of the tag information of the crane and the RFID signal of the container is greater than or equal to a first preset number, for example, the first preset number is 3 times, and the number of times of the common occurrence of the tag information of the crane and the RFID signal of the container is 5 times, it determines that the container event is currently located in the container.

As an optional implementation, when generating a loading and unloading event of the container based on the received target information, the server 130 further includes:

recording a time when the object information including the tag information of the crane and the RFID signal of the container is first received, and determining the recorded time when the object information including the tag information of the crane and the RFID signal of the container is first received as a start time of the boxing event.

According to an embodiment provided herein, in implementation, the server 130 may further record a time when the target information including the tag information of the crane and the RFID signal of the container is first received after determining that the container is in the container event. When the RFID scanner 110 mounted on the crane scans the container RFID tag, it can be considered that the crane has already driven to the container and the container loading operation is started. The recorded moment of first receiving the target information including the tag information of the crane and the RFID signal of the container can be determined as the start moment of the boxing event.

Recording a duration of time of continuously receiving the object information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck, and determining the recorded duration of time as a duration of the packing event.

According to embodiments provided herein, the server 130 may also record the duration of the continuous reception of the target information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck, when embodied. When the crane is performing a packing operation, it is necessary to place the hoisted container on the truck, the front of the crane faces both the truck and the container, and the RFID scanner 110 mounted on the crane simultaneously scans the container RFID tag and the truck RFID tag, and the crane can be considered to be performing a packing event. It is thus possible to record the duration of time for which the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is continuously received, and determine the recorded duration of time as the duration of the packing event.

It should be noted that the first preset time refers to a signal occurrence time preset in advance and used for determining whether an event is ended, for example, the second preset time may be preset to be 20 seconds, and this application is not limited specifically.

According to the embodiment provided by the application, in the implementation, after the crane loads the container on the truck and the loading operation is completed, the crane can drive away from the truck and the container, the RFID scanner 110 on the crane cannot scan any RFID tag and further cannot generate an RFID signal, and the server 130 cannot receive target information including tag information of the crane, an RFID signal of the container and an RFID signal of the truck. The server 130 is then required to determine whether the duration of the non-reception of the object information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck is greater than or equal to a first preset time. When the duration of the reception of the object information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck is not longer than or equal to the first preset time and the server 130 does not receive new object information any more, it is considered that the packing event of the container is ended, and the time when the object information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck is received is last recorded and determined as the end time of the packing event.

As an alternative embodiment, when the server 130 receives the target information including the tag information of the crane and the RFID signal of the container and the number of times of occurrence of the tag information of the crane and the RFID signal of the container together is greater than or equal to a second preset number after the server 130 determines that the container is in the container event, the container event is modified to the container unloading event.

It should be noted that the second preset number refers to a number of occurrences of a signal preset in advance and used for determining whether an event is abnormal, for example, the second preset number may be preset to be 5, which is not specifically limited in this application.

According to the embodiment provided by the application, when the crane is implemented, after the container is loaded on the truck, the container can be unloaded from the truck due to the error of the crane operator, and the loading event generated just before needs to be forcibly modified into the unloading event. When the server 130 receives the target information including the tag information of the crane and the RFID signal of the container, that is, the target information received by the server 130 does not include the RFID signal of the truck, the consecutive independent container RFID signals occur after the container loading event, and the occurrence number of the container RFID signals is greater than or equal to a second preset number, for example, the second preset number is 5, and the occurrence number of the independent container RFID signals is 8, then the container loading event of the container just generated is forcibly modified to the container unloading event.

when the target information includes the received tag information of the crane, the RFID signal of the container, and the RFID signal of the truck, the number of occurrences of the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck in common is determined.

According to the embodiment provided in the present application, when a crane unloads a container, it is first required to lift the container from the truck, and the front of the crane faces the truck and the container simultaneously, the RFID scanner 110 on the crane scans the RFID tag of the container mounted on the container and the RFID tag of the truck mounted on the truck, generates the RFID signal of the container and the RFID signal of the truck, and transmits the generated RFID signal of the container and the RFID signal of the truck together with the tag information of the crane as the target information to the transmitter 120, and the transmitter 120 transmits the target information to the server 130, so that the server 130 can analyze the target information. When the server 130 receives the target information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck, it determines the number of times of the common occurrence of the tag information of the crane, the RFID signal of the container and the RFID signal of the truck, and when the number of times of the common occurrence of the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is greater than or equal to a first preset number, for example, the first preset number is 3 times, and the number of times of the common occurrence of the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is 5 times, it determines that the unloading event of the container is currently present.

recording a time when the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is first received, and determining the recorded time when the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is first received as a start time of the unloading event.

According to the embodiment provided by the application, in implementation, the server 130 may further record the time when the target information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is first received after determining that the container is in the unloading event of the container. When the RFID scanner 110 mounted on the crane simultaneously scans the container RFID tag and the truck RFID tag, it can be considered that the crane has already driven to the truck and the container to start the unloading operation. The recorded time of first receiving the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck can be determined as the start time of the unpacking event.

The duration of the continuous reception of the target information including the tag information of the crane and the RFID signal of the container is recorded, and the duration of the recording is determined as the duration of the unloading event.

According to embodiments provided herein, the server 130 may also record the duration of the continuous reception of the target information including the tag information of the crane and the RFID signal of the container, when embodied. When the crane is performing an unpacking operation, it is necessary to lift the container from the truck to another location, and when the container leaves the truck, the front of the crane only faces the container, so that the RFID scanner 110 on the crane only scans the RFID tag of the container mounted on the container, and when the RFID scanner 110 mounted on the crane only scans the RFID tag of the container, it can be considered that the crane is performing an unpacking event. It is thus possible to record the duration of the continuous reception of the object information including the tag information of the crane and the RFID signal of the container, and to determine the recorded duration as the duration of the unloading event.

It is determined whether a duration of not receiving the target information including the tag information of the crane and the RFID signal of the container is greater than or equal to a first preset time.

And if so, determining the time of receiving the target information comprising the label information of the crane and the RFID signal of the container in the last record as the end time of the unloading event.

According to the embodiment provided by the present application, in the implementation, when the crane places the container at the designated position, and the container is unloaded, the crane can drive away from the container, the RFID scanner 110 on the crane cannot scan any RFID tag, and further, no RFID signal can be generated, the server 130 cannot receive the RFID signal transmitted by the transmitter 120, and the server 130 cannot receive the target information including the tag information of the crane and the RFID signal of the container. The server 130 is required to determine whether the duration of the non-reception of the object information including the tag information of the crane and the RFID signal of the container is greater than or equal to a first preset time. When the duration of time for which the target information including the tag information of the crane and the RFID signal of the container is not received is greater than or equal to the first preset time and the server 130 does not receive new target information any more, it is considered that the unloading event of the container is ended, and the time when the target information including the tag information of the crane and the RFID signal of the container is received is last recorded and is determined as the end time of the unloading event.

When the number of occurrences of the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck in common is greater than or equal to a first preset number, the duration of continuous reception of the target information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck is recorded.

According to the embodiment provided in the present application, when the crane performs a box moving operation, it is necessary to unload the container from the first truck, the front of the crane faces the truck and the container simultaneously, the RFID scanner 110 on the crane scans the RFID tag of the container mounted on the container and the RFID tag of the truck mounted on the truck, generates the RFID signal of the container and the RFID signal of the truck, and transmits the generated RFID signal of the container and the RFID signal of the truck together with the tag information of the crane as the target information to the transmitter 120, and the transmitter 120 transmits the target information to the server 130 for analysis by the server 130. When the server 130 receives the target information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck, the number of times of the common occurrence of the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck is determined, and when the number of times of the common occurrence of the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck is greater than or equal to a first preset number, for example, the first preset number is 3 times, and the number of times of the common occurrence of the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck is 5 times, it is necessary to record the duration of the continuous reception of the target information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck.

It is determined whether a duration of receiving the object information including the tag information of the crane, the RFID signal of the container, and the RFID signal of the truck is greater than a second preset time.

It should be noted that the second preset time is a time preset in advance and used for determining whether an event is ongoing, for example, the second preset time may be set to 20 seconds, and this application is not limited specifically.

According to the embodiment provided in the present application, in implementation, when a box moving operation is performed, so that the crane first faces the container and the truck at the same time, the RFID scanner 110 on the crane scans the RFID tag of the container mounted on the container and the RFID tag of the truck at the same time, and thus the server 130 needs to record the duration of receiving the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck and determine whether the duration of receiving the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is greater than the second preset time.

If yes, whether the received target information comprises the RFID signal of another truck or not is determined.

The duration of time for receiving the target signal including the tag information of the crane, the RFID signal of the container, and the RFID signal of another truck is determined.

It should be noted that another truck refers to a truck in which a container is finally placed during a transfer operation.

In accordance with the embodiments provided herein, in practice, because the container transfer event is the transfer of a container from a first truck to another truck, it is necessary to detect whether another RFID signal generated by the RFID scanner 110 is received. When a target signal including tag information of the crane, an RFID signal of the container, and an RFID signal of another truck is received, it is considered that the crane has traveled to the other truck at this time and is loaded. And when the duration of receiving the target information comprising the tag information of the crane, the RFID signal of the container and the RFID signal of the other truck is greater than or equal to a second preset time, determining that the container moving event of the container is currently existed when the duration of receiving the target information comprising the tag information of the crane, the RFID signal of the container and the RFID signal of the other truck is greater than or equal to the second preset time.

recording a time when the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is first received, and determining the recorded time when the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is first received as a start time of the transfer event.

According to the embodiment provided by the application, in implementation, the server 130 may further record the time when the target information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck is first received after determining that the container-in event of the container is present. When the RFID scanner 110 installed on the crane simultaneously scans the container RFID tag and the truck RFID tag, it can be considered that the crane has already driven to the truck and the container to start the box transfer operation. The recorded time of first receiving the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of the truck can be determined as the start time of the transfer event.

Recording a duration of time of continuously receiving the target information including the tag information of the crane, the RFID signal of the container and the RFID signal of another truck, and determining the recorded duration of time as a duration of the depalletizing event.

In accordance with embodiments provided herein, the server 130 may also record the duration of the continuous reception of the target information including the tag information of the crane, the RFID signal of the container, and the RFID signal of another truck, when embodied. When the RFID scanner 110 mounted on the crane scans the container RFID tag and the RFID tag of another truck, it can be considered that the crane is performing a move box event. The duration of the continuous reception of the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of another truck can be recorded, and the recorded duration can be determined as the duration of the box-moving event.

According to the embodiment provided by the application, in the implementation, when the crane loads the container on another truck and moves away from the truck and the container after the box moving operation is completed, the RFID scanner 110 on the crane cannot scan any RFID tag and further cannot generate an RFID signal, and the server 130 cannot receive target information including tag information of the crane, an RFID signal of the container and an RFID signal of another truck. The server 130 is then required to determine whether the duration of the non-reception of the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of another truck is greater than or equal to a first preset time. When the duration of the reception of the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of another truck is greater than or equal to the first preset time and the server 130 does not receive new object information any more, it is considered that the transfer event of the container is ended, and the time when the object information including the tag information of the crane, the RFID signal of the container and the RFID signal of another truck is received is last recorded and determined as the end time of the transfer event.

As an alternative embodiment, when the server 130 receives the target information including the tag information of the crane and the RFID signal of the container and the number of times of occurrence of the tag information of the crane and the RFID signal of the container together is greater than or equal to a second preset number after the server 130 determines that the container is in the container transfer event, the container transfer event is modified to the container unloading event.

According to the embodiment provided by the application, when the crane is implemented, after the container is loaded on the truck, the container can be unloaded from the truck due to the error of the crane operator, and the box moving event generated just before needs to be forcibly modified into the box unloading event. When the server 130 receives the target information including the tag information of the crane and the RFID signal of the container, that is, the target information received by the server 130 does not include the RFID signal of the truck, the consecutive independent container RFID signals occur after the container loading event, and the occurrence number of the container RFID signals is greater than or equal to a second preset number, for example, the second preset number is 5, and the occurrence number of the independent container RFID signals is 8, then the container moving event of the container which is just generated is forcibly modified into the container unloading event.

As an optional implementation, when generating a loading and unloading event of the container based on the received target information, the server 130 further includes: and after receiving the target information, judging whether the next target information is received within the overtime preset time, and if the next target information is not received within the overtime preset time, closing the loading and unloading event.

It should be noted that the timeout preset time refers to a time preset in advance and used for determining whether signal reception is timeout, for example, the timeout preset time may be preset to be 5 minutes, which is not specifically limited in this application.

According to the embodiments provided herein, in an implementation, the crane may pass through a container or a truck while moving, the RFID scanner 110 on the crane may scan the RFID tag thereon and generate a set of target information to be transmitted to the server 130, and if the received target information matches any of the three embodiments, the server 130 determines that a corresponding loading and unloading event is started and records the time when the first RFID signal is received. When the crane is driven away from the container or truck, the RFID scanner 110 on the crane cannot scan any RFID tag and further cannot generate an RFID signal, and the server 130 cannot receive the RFID signal transmitted by the transmitter 120, and at this time, it is necessary to determine whether the server 130 receives the next set of target information within the timeout preset time, and if the next set of target information is received within the timeout preset time, the signal analysis is continued according to the loading and unloading event which is determined at the beginning until a corresponding loading and unloading event is generated. If the server 130 does not receive the next set of target information within the timeout preset time, the loading and unloading event which is judged at the beginning is closed.

As an optional implementation, after the server 130 generates the loading and unloading event of the container based on the received target information, the server 130 is further configured to: and generating the waybill information corresponding to the loading and unloading event based on the generated loading and unloading event of the container and the start time and the end time corresponding to the loading and unloading event.

Note that the waybill information is a transportation certificate generated when a container is loaded or unloaded, and can be used to indicate which crane loaded or unloaded a container on which truck at what time.

According to the embodiment provided by the present application, in the implementation, the server 130 receives the tag information of the crane, and the received container RFID signal and the truck RFID signal also carry corresponding object information, so the server 130 can determine which crane is currently performing a loading and unloading event and which cargo on which truck is currently being targeted according to the information. In addition, since the server 130 records the start time and the end time of the loading and unloading event when the loading and unloading event is generated, the generated waybill information also includes the start time and the end time of the loading and unloading event.

For example, the server 130 may generate corresponding waybill information based on the fact that the tag information of the crane received by the server 130 is "crane 5", the tag information is determined to be "container 4" and "truck 3" based on the received container RFID signal and truck RFID signal, a packing event is generated, the start time of the packing event is 2021 year, 10 month, 11 days 15:00, and the end time of the packing event is 2021 year, 10 month, 11 days 15: 05. The waybill information may be "crane # 4 loaded onto truck # 3 at 10/11/2021 at 15:00-15:05, No. 5". Therefore, the server 130 can directly and automatically generate corresponding waybill information according to the acquired signals, manual recording is not needed, and the working efficiency is improved. As an alternative, the crane may be further provided with a weight detector for detecting the weight of the currently operated container and recording the weight in the waybill information.

Here, it should be noted that the above expression form of the waybill information is merely an example, and in reality, the expression form of the waybill information is not limited to the above example.
