Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics, in particular to a cargo information tracking method and device and electronic equipment. BACKGROUND

[0002] In the process of sorting goods, the information of the goods to be sorted needs to be tracked to ensure that each goods to be sorted can be allocated to the corresponding area. The cargo information delivery tracking method is generally divided into two kinds: the first kind uses sensor signals to deliver cargo information step by step; the second kind uses upper sensor signals to store data information in the queue one by one, and uses lower sensor signals to take out data information from the queue one by one.

[0003] The first cargo information delivery tracking method tracks data (i.e. cargo information) in a step-by-step delivery manner. In the process of running, when the goods are separated from the upper sensor and reach the next level sensor, the data of the previous level is written, which requires only one goods during the operation of the equipment. The delivery efficiency is low, and the distance between two goods cannot be guaranteed when continuously delivering. External interference can cause detection failure, resulting in counting error. The second cargo information delivery tracking method tracks cargo information by the principle that the upper sensor signal stores data information in the queue one by one, and the lower sensor signal takes out the cargo information in the queue one by one. In the process of running, when the goods are separated from the upper sensor, the cargo information is stored in the queue, and when the goods reach the next level sensor, the cargo information in the queue is taken out. External interference can easily cause the queue to be disordered, resulting in cargo information tracking error.

[0004] In summary, the first cargo information delivery tracking method has high accuracy and reliability, but the delivery efficiency is low, and it is not suitable for sorting equipment with high delivery speed and efficiency requirements; the second cargo information delivery tracking method can cause the order of the cargo information queue to be disordered when the sensor signal has a false action, and the error rate is relatively high and the reliability is low. Therefore, there is an urgent need for a cargo information delivery tracking method with high efficiency and high reliability. SUMMARY

[0045] Figure 2 This is a structural block diagram illustrating a cargo information tracking device according to an embodiment of this application. Detailed Implementation

[0046] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0047] The cargo information tracking solution provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0048] As attached Figure 1 As shown, the cargo information tracking method of this application embodiment includes the following steps:

[0049] Step 101: During the sorting process, the sorting center receives the first signal sent by the first sensor and the second signal sent by the second sensor.

[0050] The cargo information tracking method provided by the embodiment of the application is applied to a cargo sorting system, and the cargo sorting system comprises a sorting center and a plurality of sensors. After the to-be-sorted cargo reaches the cargo sorting system, each to-be-sorted cargo is driven by a transmission device, and a plurality of sensors are arranged at the edge of the transmission device in a spaced manner. Each sensor corresponds to an area. When the to-be-sorted cargo is conveyed to the corresponding sensor, the sorting center acquires the cargo information of the to-be-sorted cargo in a cargo information queue, determines whether the cargo belongs to the area corresponding to the current sensor according to the cargo information, and if yes, sorts the cargo to the area corresponding to the sensor. If no, it is determined that the to-be-sorted cargo does not belong to the area corresponding to the current sensor and needs to be driven to the next sensor for further sorting and judgment. Therefore, the extracted cargo information of the to-be-sorted cargo is added to the cargo information queue between the current sensor and the next sensor. When the to-be-sorted cargo reaches the next sensor, the sorting center executes the above judgment process again. The sorting center repeatedly executes the above sorting logic for each to-be-sorted cargo until the sorting of all the to-be-sorted cargos in the batch is completed.

[0051] The cargo information includes but is not limited to the target address of the cargo, the barcode information of the cargo, etc. The specific information contained in the cargo information can be flexibly set by those skilled in the art according to the sorting requirements, and the embodiment of the application does not make specific limitations on this. Furthermore, the cargo sorting system also comprises an information acquisition device such as a camera. The information acquisition device acquires the cargo information of each to-be-sorted cargo placed on the transmission device and uploads the acquired cargo information to the sorting center. The sorting center adds the cargo information of the to-be-sorted cargo to a large queue for management, so as to facilitate the comparison between the cargo information in the large queue and the extracted cargo information in the small cargo information queue between the two sensors in the subsequent sorting process.

[0052] The first sensor and the second sensor are adjacent sensors, and the first signal and the second signal are signals acquired by the sensors when the first cargo to be sorted is transmitted to the first sensor and the second sensor. The first sensor and the second sensor correspond to a small cargo information queue. Correspondingly, the second sensor and the third sensor correspond to a small cargo information queue, and so on. Adjacent two sensors correspond to a small cargo information queue for storing the to-be-sorted cargo transmitted between the two sensors. If the cargo is successfully sorted, the cargo information is no longer added to the next small cargo queue. If the cargo is not successfully sorted, it needs to be added to the next small cargo queue for further sorting and judgment.

[0053] For example, the goods sorting system includes four sensors A, B, C and D, A and B correspond to the first goods information queue, B and C correspond to the second goods information queue, C and D correspond to the third goods information queue, and the goods X first passes through A in the sorting process. The sorting center determines whether to sort to the region corresponding to A. If not, the goods information of X needs to be added to the first goods information queue. When the goods X reaches the B sensor, it is determined whether to sort to the region corresponding to B. If not, the goods information of X needs to be added to the second goods information queue. The same is true until the region of the goods X is found to complete the sorting of the goods X. It should be noted that the above example is only used to sort the goods X. In actual implementation, multiple goods need to be sorted, and the sorting method of each goods is similar to that of the goods X, which will not be repeated here.

[0054] Step 102: determining whether the time difference between receiving the second signal and the first signal is within the preset time interval range.

[0055] After the first goods to be sorted reaches the first sensor, the goods sorting center receives the first signal sent by the first sensor, determines the region to which the first goods belong, and determines that the first goods do not belong to the region corresponding to the first sensor. Therefore, it is necessary to continue to drive the first goods on the transmission device. After the first goods to be sorted leaves the first sensor, the sorting center adds the goods information of the first goods to the small goods information queue corresponding to the first sensor and the second sensor. When the first goods are driven to the second sensor, the second sensor uploads the second signal to the sorting center. The sorting center needs to determine the reliability of the sensor signal, i.e., whether it is a false sensing, according to the time difference between receiving the first signal and the second signal.

[0056] The preset time interval range is determined according to the preset transmission time length of the goods between the first sensor and the second sensor and the preset time error. For example, the transmission time length is a, and the preset time error is b. The preset time interval range is a±b, and the range formed by the two values obtained is a+b. The upper limit value of the preset time interval range is a-b.

[0057] In an optional embodiment, the preset transmission time length of the goods between the first sensor and the second sensor is determined by the following method: experimentally determining the first transmission time length of the largest goods to be sorted between the first sensor and the second sensor; experimentally determining the second transmission time length of the smallest goods to be sorted between the first sensor and the second sensor; and determining the average value of the first transmission time length and the second transmission time length as the transmission time length between the first sensor and the second sensor and preset in the sorting center.

[0058] In an alternative embodiment, the preset time error of the transmission time length between the first sensor and the second sensor is determined in the following manner: the first transmission time length of the largest to-be-sorted goods between the first sensor and the second sensor is determined through multiple experiments; the second transmission time length of the smallest to-be-sorted goods between the first sensor and the second sensor is determined through multiple experiments; for each experiment, the difference between the first transmission time length and the second transmission time length obtained through the experiment is calculated; and the average of the differences corresponding to each experiment is determined as the preset time error of the transmission time length between the first sensor and the second sensor.

[0059] It should be noted that the above is only an example of determining the preset transmission time length and the preset time error between the first sensor and the second sensor. In actual implementation, the above process is repeated to determine the preset transmission time length and the preset time error between each adjacent sensor, and is pre-set in the sorting center for management, so that the sorting center determines the preset time interval range corresponding to the two adjacent sensors based on the preset time information. It should be noted that the specific number of experiments can be flexibly set by those skilled in the art, and the present embodiment does not make specific limitations thereto.

[0060] Step 103: determining a strategy for extracting the goods information from the goods information queue according to the judgment result.

[0061] The strategy includes: extracting the goods information, prohibiting the extraction of the goods information, and deleting the goods information.

[0062] An alternative way of determining a strategy for extracting the goods information from the goods information queue according to the judgment result can be as follows:

[0063] In the case where the time difference between the reception of the second signal and the first signal is within the preset time interval range, it is determined to extract the goods information of the first goods from the goods information queue; in the case where the time difference between the reception of the second signal and the first signal is less than the lower limit value of the preset time interval range, it is determined that the sensor malfunctions and prohibits the extraction of the goods information of the first goods from the goods information queue; and in the case where the time difference between the reception of the second signal and the first signal is greater than the upper limit value of the preset time interval range, it is determined to delete the goods information of the first goods from the goods information queue.

[0064] In the case of extracting the cargo information of the first cargo from the cargo information queue, the sorting center determines whether the first cargo belongs to the area corresponding to the second sensor based on the cargo information of the first cargo, and if it belongs, sorts the first cargo to the area corresponding to the second sensor, and the sorting of the first cargo is completed; if it does not belong, continue to convey the first cargo to the next sensor of the second sensor, convey the first cargo to the next sensor of the second sensor and add the cargo information of the first cargo to the small cargo information queue corresponding to the second sensor and the third sensor, and when the first cargo reaches the third sensor, the sorting center determines whether the signal of the first cargo collected by the third sensor is reliable according to the signals uploaded by the second sensor and the third sensor (i.e. the signals collected by the sensor when the first cargo reaches the sensor), extracts the cargo information of the first cargo from the small cargo information queue corresponding to the second sensor and the third sensor in the case of judging that the signal is reliable, and determines whether the first cargo belongs to the area corresponding to the third sensor. In this way, the sorting process of the first cargo ends until the first cargo finds the corresponding area. The above is only an example of tracking information when sorting the first cargo, and in the actual implementation process, the above process needs to be repeated to complete the sorting of each cargo to be sorted.

[0065] The cargo information tracking method provided by the embodiment of the application receives the first signal sent by the first sensor and the second signal sent by the second sensor in sequence in the process of sorting the cargo; determines whether the time difference between receiving the second signal and the first signal is within the preset time interval range; and determines the strategy of extracting the cargo information from the cargo information queue according to the determination result, such as extracting the cargo information, prohibiting the extraction of the cargo information, and deleting the cargo information. The cargo information tracking scheme provided by the embodiment of the application can support multiple cargos during the operation of the cargo sorting system, and therefore can realize efficient and low cargo information transmission tracking. In addition, the comparison mechanism of the cargo transmission time length and the preset time interval range is added, the sensor malfunction can be investigated through the comparison result, and the reliability of the cargo information transmission tracking can be effectively improved.
