Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

The embodiment of the application can be applied to the fields of storage and logistics, and logistics is a process for organically combining functions of transportation, storage, loading, unloading, transportation, packaging, circulation processing, distribution, information processing and the like to realize user requirements according to actual needs in the process of physically flowing articles from a supply place to a receiving place. The logistics object refers to an object of logistics processing, such as a package, an unpackaged article to be shipped, and the like.

The embodiment of the application can be applied to various acquisition devices, and the electric quantity of the acquisition devices is saved, such as a Personal Digital Assistant (PDA), a tour robot, a sensor and the like. The PDA is a digital tool for assisting personal work, and includes a scanner, a barcode scanner, a Radio Frequency Identification (RFID) reader, a Point Of Sale (POS) terminal, and the like, and may also include a tablet computer, a mobile phone, a handheld game machine, and the like. The acquisition equipment can acquire data through modes such as scanning, photographing, radio frequency identification and sensor identification.

In the embodiments of the present application, a PDA is taken as an example for discussion, in actual processing, the method is not limited to determining the commodity information in a manner of scanning a barcode, a two-dimensional code, and the like, and may also be used for acquiring data such as the commodity information in other manners, for example, the commodity information is identified by a sensor, and the data is identified by photographing.

Taking the field of logistics as an example, the PDA may include a scanning device such as a scanner, for example, a scanning gun for a warehouse, a scanning device for a logistics worker, and the like. These PDAs are battery powered, thereby reducing battery power consumption and increasing battery life by reducing the number of data transmissions.

In the example shown in fig. 1, the scanning gun is a PDA, for example, when used in a warehouse. The operation of scanning the warehouse by the PDA and then storing the scanned warehouse in the warehouse is called warehousing, the operation of scanning the warehouse in the warehouse and then taking out the scanned warehouse is called ex-warehouse, and then the commodities can be packaged as logistics objects to be subjected to logistics processing such as sorting, transportation, dispatching and the like. Fig. 1A is a schematic diagram of a scanning gun scanning goods in a warehouse for warehousing and ex-warehouse.

As shown in fig. 1B. In other examples, the scanning gun can record the moving track so as to determine the position of the warehouse where the commodity is stored, and the like.

In the process of commodity warehouse-out, the commodities can be scanned to obtain the commodity information, the warehouse location is scanned to obtain the warehouse location information, so that the corresponding quantity of commodities are subtracted from the commodity warehouse-in information corresponding to the warehouse location until all the commodities in the warehouse location are taken out, and the commodity warehouse-in information corresponding to the warehouse location can be set to be empty or no commodity warehouse-in information and the like.

In the process of warehousing and ex-warehouse of the commodity, warehouse operation data acquired by the scanning gun is transmitted to a management end of the warehouse, so that the management end can record and manage the commodity stored in the warehouse conveniently. In addition, the scanning gun also can periodically send heartbeat signals or other online signals to the management terminal to mark the online survival of the scanning gun, and the scanning gun also can send self equipment information such as electric quantity information, running time and the like to the management terminal, so that the management terminal can manage the scanning gun. In step 102, the warehouse operation data, the on-line signal, the device information, and other data may be sent to the management end through the transmission interface.

However, these data transmission delays are different, and therefore the priority information of the data can be detected in step 104. Some of them need to be sent immediately, such as an on-line signal, etc. can be transmitted to the destination end in real time through the transmission interface in step 106. And some data can be sent after delaying for a period of time, such as warehouse operation data and the like, can be buffered in step 108 and sent in a packed mode after delaying for a period of time, so that the power consumption of the scanning gun can be reduced, namely, the data which can be sent in a delayed mode are sent in a packed mode after delaying for a period of time, and the transmission times of the data are reduced.

Referring to fig. 2, a flowchart illustrating steps of an embodiment of a data transmission method according to the present application is shown, which may specifically include the following steps:

step 202, in the case of transferring data by calling a transfer interface, detecting priority information of the data.

The scanning gun can scan commodities, warehouse positions and the like to determine warehouse operation data, can generate data such as online signals, equipment information and the like, can transmit the data to the management end, can set priority marks for the data before transmitting the data to the management end, can add the priority marks into the data, and can set priority in the system of the PDA according to data types in advance in other embodiments, so that the priority information of the data can be determined when the data are transmitted through the transmission interface.

In one example, a priority identifier may be added to the data, and then the transmission interface may be invoked to transmit the data, and after the data is received by the interface, the priority identifier of the data may be detected by the system service to determine priority information, such as a priority level, whether the data is delayable, a delayable delay time, and the like.

In another example, priority information of different types of data may be set in advance in the system service, in the case of invoking the transmission interface to transmit data, the interface may invoke the system service to detect the priority information of the data, the system service may determine the data type of the data, and then determine the priority information based on the data type, such as the priority level, whether the data can be delayed, the delay duration of the data can be delayed, and the like.

The priority information may be set as the level information with high or low priority, or may also be set as the time information of whether to delay or not, or set as the identifiers 0, 1, etc., which is not limited in the embodiment of the present application, and may be specifically set according to the requirements, so that the priority of the data can be distinguished.

And step 204, judging the condition met by the priority information of the data.

The embodiment of the application can set conditions aiming at the priority information in advance, and different conditions correspond to different sending modes of the data. The first condition is a condition for sending data in real time, and the data with the priority information meeting the first condition can be directly sent through the transmission interface. The second condition is a condition for delaying sending data, and data with priority information meeting the second condition can be firstly cached, and then the transmission interface is called to send the data under the condition of meeting a third condition. The third condition is an issue condition of the cache data, and may be specifically set according to a requirement.

After the priority information of the data is detected, the condition satisfied by the priority information of the data may be determined, and step 206 is performed if the first condition is satisfied, and step 208 is performed if the second condition is satisfied.

In other examples, only one condition may be set, and the condition may be a condition for transmitting data in real time, and step 206 is executed if the condition is satisfied, and step 208 is executed if the condition is not satisfied; or the condition is set as the condition for delaying the transmission of the data, the step 208 is executed if the condition is satisfied, and the step 206 is executed if the condition is not satisfied.

Step 206, sending the data through the transmission interface.

For data with priority information meeting the condition of sending data in real time, such as the first condition, the data can be immediately sent to a destination end, such as a management end of a warehouse, through the transmission records, so that the timeliness of the data cannot be influenced, and the normal execution of transactions is ensured.

Step 208, caching the data.

For data whose priority information satisfies a condition for delaying transmission of data, such as the second condition, the data may be buffered, such as stored in a buffer or buffer queue of the device.

In an example, the data is stored in the buffer queue according to a set rule, for example, the data is stored in the buffer queue according to the sequence of the remaining time of the delay time, or the data is stored in the buffer queue according to the sequence of data acquisition, or the data is buffered according to the size of the data and the type of the data.

In other embodiments, different data may correspond to different destination addresses, for example, device information and the like are sent to a management end for device management, while warehouse operation data is sent to a management end for inventory management, or sent to different management ends based on different operations of warehousing and ex-warehousing. For the case that the destination addresses of different data are different, different buffer queues may be created for different destination addresses, so that when buffering data, the data is stored in the buffer queue corresponding to the destination address according to a set rule, that is, the data is stored in different buffer queues based on the destination address, and the rule for storing the data in the buffer queue may be similar to the above example.

Step 210, determining whether the cached data meets a third condition. If yes, go to step 212, otherwise, go back to step 210 to continue the determination.

The third condition is an issuing condition of the cache data, and the third condition can be set according to requirements. The third condition includes at least one of: a buffer quantity condition, a data quantity condition and a delay condition. The buffer amount condition and the data amount condition may also be referred to as an amount condition, and refer to a condition that the amount of data to be transmitted at a time is satisfied, and the amount may be the number of pieces of data or the data amount of the data. The delay condition refers to a condition of a delay time period of data, and the data can be transmitted in a case where the data reaches a maximum delay time.

For the quantity condition, when data is stored in the buffer queue, the quantity of the data in the queue can be determined. The buffer number condition may be determined according to the number of the data, and when the data is stored in the buffer queue (enqueue), the total number of the data stored in the buffer queue may be +1, and it is determined whether the total number meets a number threshold corresponding to the buffer number condition, and if the buffer number condition is met, step 212 is executed. If the quantity condition is determined according to the cache data quantity, the data quantity of the data may be added to the total data quantity of the data stored in the cache queue when the data is enqueued, and if the total data quantity exceeds the data quantity threshold corresponding to the quantity condition, step 212 is executed if the quantity condition is satisfied. In an optional embodiment, the caching the data includes: storing the data into a buffer queue according to a set rule, and adding the total data volume of the buffer data in the buffer queue to the data volume of the data; and judging whether the total data volume meets a data volume condition. In another optional embodiment, the caching the data includes: storing the data into a cache queue according to a set rule, and adding one to the total amount of the cache data in the cache queue; and judging whether the total number meets a cache number condition.

For the delay condition, the priority information of each data may correspond to a delay duration, and when the data is stored in the buffer queue, the priority information may also be arranged according to the length sequence of the delay durations, so as to determine whether the delay time of the data reaches the delay duration of the data, and if the delay time reaches the delay duration, the delay condition is met, and step 212 is executed.

And step 212, combining the buffered data into a data packet and sending the data packet through the transmission interface.

For the buffered data meeting the third condition, the buffered data may be combined and packaged to form a data packet, and then the data packet may be sent through the transmission interface. The cached data can be combined according to a set rule, and then the combined data is packaged to obtain a data packet. The data combination and packaging can be realized in various ways, for example, the data can be combined according to a certain sequence and then packaged to obtain a data packet, or the data can be randomly combined and then packaged to form a data packet, and the like. An example of data combination packing may be as shown in fig. 3:

for the stored data D1, data D2, and data D3, the data D1, data D2, and data D3 may be sequentially arranged in the buffer queue, and a message header and a message tail may be encapsulated to obtain a corresponding data packet. The method is similar to a train, a data packet is regarded as a train, each data is a carriage, a message header can be regarded as the head of the train, a message tail can be regarded as the tail of the train, the number of the carriages required to be hung on the train can be determined and the carriages are connected to form the train when the data which can be delayed is transmitted every time, namely the data are combined and encapsulated into the data packet. The data D1 corresponds to priority information p1 and delay time t1, the data D2 corresponds to priority information p2 and delay time t2, and the data D3 corresponds to priority information p3 and delay time t 3. Wherein, the time lengths of t1, t2 and t3 can be the same or different, and the priorities of p1, p2 and p3 can be the same or different.

In one example, the delay time of the data cached in the cacheable queue may be, after the delay time of any data reaches the delay time, combined and packed with other data in the cacheable queue, and then sent out. Each data packet can be provided with a data volume sending threshold, so that in the process of combined packaging, combination can be performed based on the data volume sending thresholds, for example, data can be selected according to the sequence of entering a buffer queue or the sequence of the remaining time of the delay duration. The remaining time of the delay duration may be a difference between the delay duration of the data and the cache duration.

In summary, the PDA device such as a scanning gun is used to scan the goods stored in the warehouse, and the PDA also needs to interact with other devices to transmit data, such as the scanned goods location information, in the case of transferring data by calling a transfer interface, priority information of the data may be detected, and if the priority information of the data satisfies a first condition, the data is transmitted through the transfer interface, thus, necessary data can be transmitted immediately, if the priority information of the data meets a second condition, the data is cached, in case the buffered data fulfils a third condition, the buffered data are combined into data packets and sent over said transmission interface, by buffering and assembling of the data, the data transmission device can transmit a plurality of data together, and reduces the transmission times of the data, thereby reducing the power consumption of the equipment and prolonging the service life of the battery.

In the embodiment of the application, the warehouse operation comprises warehouse-in operation, warehouse-out operation and the like, and correspondingly comprises warehouse operation data, therefore, the warehouse operation data can count warehouse-out and warehouse-in operations of the warehouse, can also determine information such as warehouse-in and warehouse-out positions and the like, the inventory quantity of the warehouse may also be determined based on warehouse operational data, for which the inventory quantity may be compared to a pre-set restocking threshold, the replenishment threshold is the threshold of warehouse replenishment, if not less than the replenishment threshold, no replenishment is needed, if the stock quantity is less than the replenishment threshold, a replenishment request can be generated, the replenishment request can carry the quantity and the like required to be replenished, can record the stock position and the like without the stock, can add parameters into the replenishment request according to the requirement, can send the replenishment request, the replenishment request can also be used as data, and is determined to be sent in real time or sent after being integrated with other data through priority information. In another example, multiple replenishment thresholds may be set, for example, the first replenishment threshold is a replenishment threshold that is sent in a delayed manner, and the second replenishment threshold is a replenishment threshold that is sent in real time, so that a sending manner is determined based on the replenishment thresholds, and if the first replenishment threshold is met, a replenishment request is generated to wait for sending, more delivery operations are performed in the process, and if the second replenishment threshold is met, the replenishment request is sent immediately.

In the embodiments Of the present application, the operation Of the warehouse is mainly taken as an example, and in the actual processing, the present application is not limited to the use scenario Of the warehouse, but may also be applied to a scenario, for example, an Internet Of Things (IOT) scenario, for example, in a refrigerator, the refrigerator may identify an object stored therein, record when the object is taken out or put in, determine the recorded data as real-time transmission, delayed transmission, and the like based on priority information, and at the same time, count the number Of objects Of each type in the refrigerator, report a replenishment request such as a remaining number Of the object Of the type in the case that the number is lower than a certain threshold, and push the replenishment request to the user equipment Of the user, an application program on the user equipment, and the like, thereby notifying the user Of replenishment. For example, when the number of the object items such as milk, drinking water, vegetables, meat, etc. in the refrigerator is less than a certain threshold value, a replenishment request is generated, the issuance mode is determined based on the priority information, and the replenishment request is issued, and then the user is notified of the replenishment. Therefore, in a family IOT scene, the use condition of various article objects can be reported, the residual quantity can be counted, and the article objects can be supplemented when needed.

On the basis of the above embodiment, the embodiment of the present application further provides a data transmission method, which can pack and send out data that needs to be delayed, so as to add consumption on the electric quantity of the device, and for data that needs to be sent out immediately, the data can also be transmitted to the destination end in time through the transmission interface, thereby ensuring real-time requirements of the data.
