Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

In order to realize the automatic collection of information of logistics items of different lengths and increase the length range of the logistics items applicable to automatic collection, a data collection system, method, device, electronic equipment and storage medium are proposed in the embodiments of this application, which will be described in detail below.

Refer to Figure 1. Figure 1 is a first schematic diagram of a data collection system implemented in this application, including:

The length sensor 101, the first weighing conveyor belt 102, the second weighing conveyor belt 103, the controller 104, the length sensor 101 is arranged at the inlet end of the first weighing conveyor belt 102, and the second weighing conveyor belt 103 is arranged at the first weighing The conveyor belt 102 is downstream in the conveying direction and is adjacent to the first weighing conveyor belt.

The length sensor 101 is used to collect the length of the object to be detected.

In one embodiment, the length sensor can measure the length of the object in the following manner. For example, the object to be detected passes under the length sensor at a certain speed, and the second type signal is generated when the length sensor detects the object to be detected. The first type signal is generated after the detection object passes, that is, the first type signal is generated when the object to be detected is not detected. The length of the object to be detected can be obtained by the time between the second type signal and the first type signal (that is, the duration of the second type signal) and the passing speed of the object to be detected. This application does not limit the type and detection method of the length sensor, and can refer to related length measurement technology. The first type of signal and the second type of signal can be customized according to the actual situation. In an example, the first type signal is a rising edge signal, and the second type signal is a falling edge signal; in an example, the first type signal is a falling edge signal, and the second type signal is a rising edge signal.

The controller 104 is configured to receive the length of the object to be detected collected by the length sensor 101; according to the length of the object to be detected, the length of the first weighing conveyor belt 102, and the length of the second weighing conveyor belt 103, from the first weighing conveyor belt 102 At least one weighing conveyor belt is selected from the second weighing conveyor belt 103; the selected at least one weighing conveyor belt is instructed to collect the weight of the object to be inspected; wherein the total length of the at least one weighing conveyor belt is greater than the length of the object to be inspected.

In one embodiment, the controller may be a PLC (Programmable Logic Controller, Programmable Logic Controller), etc. The controller may communicate with the length sensor, the first sensor, and the second sensor in a wired or wireless manner to perform calculations. And control. When the length of the object to be detected is less than the length of the first weighing conveyor belt, the controller can select the first weighing conveyor belt to collect the weight of the object to be detected; when the length of the object to be detected is less than the length of the second weighing conveyor belt, the controller You can choose the second weighing conveyor belt to collect the weight of the object to be inspected; when the length of the object to be inspected is greater than the length of the first weighing conveyor belt, and the length of the object to be inspected is greater than the length of the second weighing conveyor belt, and the first weighing conveyor belt When the total length with the second weighing conveyor belt is greater than the length of the object to be inspected, the controller can select the first weighing conveyor belt and the second weighing conveyor belt to collect the weight of the object to be inspected.

The first weighing conveyor belt 102 and the second weighing conveyor belt 103 are used to collect the weight of the object to be detected separately or jointly according to the instructions of the controller 104.

The length of the second weighing conveyor belt 103 and the length of the first weighing conveyor belt 102 may be the same or different, and both fall within the protection scope of the present application.

It can be seen that the data collection system provided by the embodiment of the present application introduces two weighing conveyor belts. When the length of the object is short, one of the weighing conveyor belts is instructed to collect the weight of the object separately. When the length of the object is longer, two weighing belts can be combined. The conveyor belt collects the weight of objects together, so that different information collection methods can be adopted for objects of different lengths, so as to realize automatic information collection of objects of different lengths and improve the utilization rate of weighing equipment.

In a possible implementation, the controller is specifically configured to: when the smaller of the length of the first weighing conveyor belt and the length of the second weighing conveyor belt is greater than the length of the object to be detected, instruct the first weighing Either the conveyor belt or the second weighing conveyor belt collects the weight of the object to be inspected; when the length of the first weighing conveyor belt and the length of the second weighing conveyor belt is smaller than the length of the object to be inspected, and the first weighing When the larger of the length of the heavy conveyor belt and the length of the second weighing conveyor belt is greater than the length of the object to be inspected, it indicates that the longer weighing conveyor belt of the first weighing conveyor belt and the second weighing conveyor belt collects the object to be inspected The weight; when the larger of the length of the first weighing conveyor belt and the length of the second weighing conveyor belt is less than the length of the object to be inspected, and the total length of the first weighing conveyor belt and the second weighing conveyor belt is greater than the object to be inspected When the length of the first weighing conveyor belt and the second weighing conveyor belt are combined to collect the weight of the object to be inspected; when the total length of the first weighing conveyor belt and the second weighing conveyor belt is less than the length of the object to be inspected, it is determined that the weight of the object to be inspected The detected object is an over-length piece, so abnormal handling is performed.

For example, the length of the first weighing conveyor belt is 5 meters, and the length of the second weighing conveyor belt is 10 meters; when the length of the object to be inspected is less than 5 meters, either the first weighing conveyor belt or the second weighing conveyor belt can be responsible for mining Weight; when the length of the object to be detected is between 5 meters and 10 meters, the second weighing conveyor belt can measure the weight alone; when the length of the object to be detected is between 10 meters and 15 meters, the first weighing The conveyor belt and the second weighing conveyor belt can be combined for weighing.

Wherein, when the total length of the first weighing conveyor belt and the second weighing conveyor belt is less than the length of the object to be inspected, it is determined that the object to be inspected is an ultra-long piece, so as to perform abnormality processing. Abnormal handling can be achieved in many ways, for example, sending an alarm signal through the controller, controlling the weighing conveyor belt to stop, and then weighing manually, or by controlling the conveying direction of the conveyor belt to connect the object to other weighing equipment Methods such as weighing are not limited in this application.

It can be understood that when the length of the object to be detected is equal to the lesser of the length of the first weighing conveyor belt and the length of the second weighing conveyor belt, it can be instructed to collect either of the first weighing conveyor belt and the second weighing conveyor belt. The weight of the object to be inspected may also indicate that the longer weighing conveyor belt among the first weighing conveyor belt and the second weighing conveyor belt collects the weight of the object to be inspected. When the length of the object to be detected is equal to the larger of the length of the first weighing conveyor belt and the length of the second weighing conveyor belt, the longer one of the first weighing conveyor belt and the second weighing conveyor belt can be indicated. The conveyor belt collects the weight of the object to be detected, or instructs the first weighing conveyor belt and the second weighing conveyor belt to jointly collect the weight of the object to be detected.

In one embodiment, in order to increase the accuracy of the collected weight, the collection needs to be performed when the object to be detected is completely within the range of the weighing conveyor belt. For example, when the controller selects the first weighing conveyor belt to collect the weight of the object to be inspected, it needs to ensure that the physical weight to be inspected is collected when all the objects to be inspected are within the range of the first weighing conveyor belt; for example, when the controller selects When the second weighing conveyor belt collects the weight of the object to be detected, it is necessary to ensure that the physical weight to be detected is collected when all the objects to be detected are within the range of the second weighing conveyor belt; for example, when the controller selects the first weighing conveyor belt and When the second weighing conveyor belt collects the weight of the object to be detected, it is necessary to ensure that the physical weight to be detected is collected when all the objects to be detected are within the combined range of the first weighing conveyor belt and the second weighing conveyor belt.

In a possible implementation, referring to FIG. 2, the above-mentioned system further includes a first sensor 105, and the first sensor 105 is arranged at the exit end of the second weighing conveyor belt 103.

The first sensor 105 is used to detect whether the object to be detected passes through, and can send a second type of signal to the controller when it detects the arrival of the head of the object to be detected, and can send a signal to the controller when it detects that the tail of the object to be detected is leaving Send the first type of signal.

Wherein, the above-mentioned first sensor may be multiple types of sensors, for example, a photoelectric sensor, a pressure sensor, etc., which is not limited in this application. In the embodiments of the present application, the end of the object to be detected pointing to the transmission direction is called the head, and the end of the object to be detected facing away from the transmission direction is called the tail.

The controller 104 is further configured to obtain the weight of the object to be detected from the selected at least one weighing conveyor when receiving the first type signal of the first sensor.

Wherein, the first weighing conveyor belt and/or the second weighing conveyor belt may be stored in the preset buffer space after the weight information of the object to be detected is obtained by weighing. After the controller receives the first type signal of the first sensor, that is, after the received signal of the first sensor is converted from the second type signal to the first type signal, the controller obtains the to-be-detected signal from the preset buffer space. The weight information of the object.

In a possible implementation, referring to FIG. 3, the foregoing system further includes: a bag pulling conveyor belt 106, which is located upstream of the conveying direction of the first weighing conveyor belt 102 and may be adjacent to the first weighing conveyor belt 102; The bag-drawing conveyor belt 106 can receive the objects to be inspected from other equipment, and transfer the objects to be inspected to the entry end of the first weighing conveyor belt 102.

Among them, the bagging conveyor 106 can receive the objects to be detected from the upstream of the conveying direction, and convey the received objects to be detected downstream. By controlling the transmission speed of the bagging conveyor 106 to be greater than its upstream transmission speed, it can be extended. The distance between the objects to be detected on the bag conveyor.

In a possible implementation, referring to FIG. 4, the above system further includes a first sensor 105 and a second sensor 108. The first sensor 105 is arranged at the exit end of the second weighing conveyor belt 103, and the second sensor 108 is arranged at The output end of the first weighing conveyor belt 102.

The first sensor 105 can be used to detect whether an object to be detected passes through, and can send a first type of signal to the controller 104 when it is detected that the tail of the object to be detected is out of the detection of the first sensor 105.

The second sensor 108 can be used to detect whether the object to be detected passes through, and can send the first type of signal to the controller 104 when it is detected that the tail of the object to be detected is out of the detection of the second sensor 108.

Among them, the first sensor 105 and the second sensor 108 can send a second type of signal to the controller 104 when the head of the object to be detected is detected. When the first sensor 105 detects that the tail of the object to be detected is separated from the first sensor 105 The first type signal is sent to the controller 104 during detection; the first type signal is sent to the controller 104 when the second sensor 108 detects that the tail of the object to be detected is separated from the detection of the second sensor 108. In one embodiment, the above-mentioned signal is only used to distinguish whether the object to be detected passes through, and the type of the signal is not limited in this application. For example, the first sensor 105 and the second sensor 108 can also be used when the head of the object to be detected is detected. The part may send the first type signal to the controller 104, and send the second type signal to the controller 104 when it detects that the tail of the object to be detected is out of the detection of the first sensor 105 and the second sensor 108.

Wherein, the second sensor 108 and the first sensor 105 may be the same or a different type of sensor. Since the above-mentioned second sensor 108 is arranged at the exit end of the first weighing conveyor belt 102, when the second sensor 108 detects the departure of the tail of the object to be detected, that is, when the controller 104 receives the first sensor sent by the second sensor 108 Type signal, that is, when the controller 104 receives the signal sent by the second sensor 108 from the second type signal to the first type signal, it can be determined that the object to be detected has separated from the first weighing conveyor belt, and the first weighing conveyor belt 102 pairs The current weight detection of the object to be detected has been completed; when the controller 104 receives the first type signal sent by the first sensor 105, that is, when the controller 104 receives the first sensor 105 signal, it changes from the second type signal to the first type signal. When the type signal is used, it can be determined that the object to be detected has separated from the second weighing conveyor belt, and the second weighing conveyor belt 103 has completed the weight detection of the current object to be detected.

The controller 104 is also used to control the bagging conveyor 106 to stop transporting the next object to be detected to the first weighing conveyor 102 after receiving the length of the object to be detected collected by the length sensor, until it receives the first object to be detected from the second sensor 108 A type signal, according to the first type signal of the second sensor 108 to control the pulling conveyor belt 106 to transport the next object to be detected to the first weighing conveyor belt 102; and, after receiving the first type signal of the second sensor 108, control The first weighing conveyor belt 102 stops transporting the next object to be detected to the second weighing conveyor belt 103 until it receives the first type signal of the first sensor 105, and controls the first weighing conveyor belt according to the first type signal of the first sensor 105 102 conveys the next object to be inspected to the second weighing conveyor belt 103.

In this way, the weighing section composed of the first weighing conveyor belt 102 and the second weighing conveyor belt 103 can hold two packages at the same time, which improves the data collection efficiency of the packages; and, due to the above mechanism, the first weighing conveyor belt 102 and the first weighing conveyor belt 102 can be realized. There is only one object to be detected on the second weighing conveyor belt 103 at any time. Therefore, when the first weighing conveyor belt 102 and the second weighing conveyor belt 103 are used to perform the weight detection of the object to be detected, the detection result is accurate.

In a possible implementation, referring to FIG. 5, a third sensor 109 may be provided at the exit end of the bagging conveyor 106. After the controller 104 receives the length of the object to be detected collected by the length sensor 101, when the third sensor When the sensor 109 detects the object to be detected, it sends an emergency stop instruction to the bagging conveyor 106 to control the bagging conveyor 106 to stop transporting the next object to be detected to the first weighing conveyor 102. When the first type signal from the second sensor 108 is received again, it can be determined that the object to be detected on the first weighing conveyor belt 102 has been detected. The controller 104 can restart the bag-drawing conveyor belt 106 and send to the first weighing conveyor. The conveyor belt 102 conveys the object to be inspected.

Wherein, the aforementioned third sensor 109 is arranged at the exit end of the bag-drawing conveyor belt 106, and can be at a certain distance from the end of the bag-drawing conveyor belt 106, so as to facilitate the stopping of the object to be detected on the bag-drawing conveyor belt 106.

In a possible implementation manner, after receiving the first type signal of the second sensor 108, that is, after the signal of the second sensor 108 is changed from the second type signal to the first type signal, determine the tail of the object to be detected currently Having left the first weighing conveyor belt 102, the controller can control the first weighing conveyor belt 102 to stop transporting the next object to be inspected to the second weighing conveyor belt 103 until it is determined that the object to be inspected on the second weighing conveyor belt has been weighed Finished, that is, the controller 104 receives the first type signal sent by the first sensor 105, and transports the object to be detected to the second weighing conveyor 103 again. Therefore, it is ensured that there is only one object to be detected on the second weighing conveyor belt 103 at the rear end at any time, and the accuracy of the weighing result is ensured.

In a possible implementation manner, referring to FIG. 6, a telescopic machine 107 is connected to the inward end of the bag-drawing conveyor 106.

The telescopic machine 107 is used to transport the object to be inspected to the entry end of the bag-drawing conveyor belt, and the conveying speed of the bag-drawing conveyor belt is greater than that of the telescopic machine.

Wherein, the above-mentioned telescopic machine can be controlled by a controller or manually by a person to expand and contract the length and swing in the left-right direction. For example, when the system is used to detect express items on a logistics vehicle, by controlling the expansion and contraction of the telescopic machine 107, the entry end of the telescopic machine 107 can be close to the logistics vehicle, thereby facilitating the transportation of the object to be detected to the bag conveyor belt , Improve detection efficiency and reduce labor costs.

In a possible implementation, referring to FIG. 7, the above system further includes: a code reading camera 110, which is located above the first weighing conveyor belt 102 or the second weighing conveyor belt 103.

Among them, the code-reading camera is located above the first weighing conveyor belt or the second weighing conveyor belt, and the code-reading camera can be controlled according to the specific erection position of the code-reading camera to collect the barcode. For example, the code-reading camera can be set at the first weighing conveyor. At the entry end of the conveyor belt, the barcode of the object to be detected can be collected as soon as possible. In an example, the number of code reading cameras can be multiple, for example, 3, 5, or 6, etc. Each code reading camera can be set up at different positions above the first weighing conveyor belt or the second weighing conveyor belt, and one In the example, the shooting angles of the code-reading cameras are not exactly the same. For example, some code-reading cameras collect barcodes from directly above the first or second weighing conveyor belt, and some of the code-reading cameras collect barcodes from the first or second weighing conveyor belt. The barcode is collected on the upper left side of the second weighing conveyor belt, and some code-reading cameras collect barcodes from the upper right side of the first weighing conveyor belt or the second weighing conveyor belt, thereby increasing the probability of successful barcode collection of the object to be detected.

The length sensor 101 can also be used to detect whether an object to be detected passes through, and can send a second type of signal to the code reading camera 110 when the head of the object to be detected is detected.

Wherein, the second type signal is sent to the code reading camera 110 through the length sensor 101, which can facilitate the code reading camera 110 to control the code reading timing. For example, when there is no need to detect the object to be detected, the code reading camera 110 is in a dormant state. When the object to be detected passes through the length sensor 101, the length sensor 101 can send a second type of signal to the code reading camera 110 to wake up the code reading camera; After receiving the second type signal sent by the length sensor 101, the controller 104 wakes up the code reading camera, so that the code reading camera starts to perform code reading work.

The barcode reading camera 110 is used to collect the barcode of the object to be detected after receiving the second type signal of the length sensor.

Wherein, the barcode reading camera collects the barcode of the object to be detected, which can be collected in a variety of ways, for example, by shooting the logistics list of the object to be detected or the tracking number or barcode of the logistics list, etc., to obtain the barcode of the object to be detected .

In a possible implementation, referring to FIG. 8, the above system further includes a processor 113, a code reading camera 110, a body measuring camera 111, and an abnormality handling conveyor belt 112. The abnormality handling conveyor belt 112 is located in the conveying direction of the second weighing conveyor belt 103. The downstream of, may be adjacent to the second weighing conveyor belt 103.

The volume of the object to be detected is detected by the measuring camera 111, and the obtained volume information can be sent to the processor, and the obtained volume information can be bound with the barcode by the processor.

In a possible implementation manner, after the barcode reading camera 110 collects the barcode of the object to be detected, the barcode information may also be sent to the processor, and the barcode and the first weighing conveyor 102 and/or the first weighing conveyor belt 102 and/or the second The weight information and volume information collected by the second weighing conveyor 103 are bound to facilitate further processing of the object to be detected.

Among them, the abnormal handling conveyor belt 112 can process the abnormal objects detected by the above-mentioned information collection system. For example, when the length of the object to be detected exceeds the processing range of the first weighing conveyor belt 102 and the second weighing conveyor belt 103, the The object is marked as an abnormal object. When the abnormal object is transported to the abnormality handling conveyor belt 112, the processor 113 can send an alarm signal, and the controller 104 can control the abnormality handling conveyor belt 112 to make an emergency stop, so that the abnormal object can be manually processed. Weigh. In one embodiment, the abnormality handling conveyor belt may also be a conveyor belt that is different from the normal conveying process of the object to be inspected. For example, when the processor determines that the object to be inspected is not an abnormal object, it is conveyed through the normal object conveyor belt, and when the processor determines When the object to be detected is an abnormal object, the conveying direction is changed through the three-way interface connected at the back end of the second weighing conveyor belt, and the abnormal object is conveyed to the abnormal handling conveyor belt for processing. Among them, the judging criteria for abnormal objects can be customized according to the actual situation, such as unchecked logistics information, overweight or overlength objects, etc., all within the protection scope of this application.

The processor 113 is configured to receive the weight of the object to be detected collected by at least one weighing conveyor, the barcode of the object to be detected collected by the barcode reading camera 110, and the volume of the object to be detected collected by the body measuring camera 111; Whether the weight, barcode and volume are abnormal, if there is no abnormality, the weight, volume and barcode of the same object to be detected will be associated; if there is an abnormality, the abnormal object to be detected will be controlled to stay on the abnormal handling conveyor 112, and the first scale will be controlled The heavy conveyor belt 102 and the second weighing conveyor belt 103 immediately stop working or control the first weighing conveyor belt 102 and the second weighing conveyor belt 103 to stop working after each carrying an object to be detected.

In an example, the processor 113 may determine the weight, barcode, and volume of the same object to be detected according to the order in which the object to be detected enters the first weighing conveyor belt 102. For example, as shown in FIG. 8, when the length of the object to be detected by the length sensor 101, the barcode reading camera 110 and the body measuring camera 111 located at the entrance of the first weighing conveyor belt 102 simultaneously collect the barcode and volume of the object to be detected. After the detection of the length of the object is completed, the barcode and volume of the object to be detected are also detected, and then according to the length of the object to be detected, the corresponding weighing method is used to obtain the weight of the object to be detected. In an example, the processor 113 numbers the weight, barcode, and volume according to the sequence of data acquisition. For example, the first weight acquired is numbered as weight 1, and the first barcode acquired is numbered as barcode 1. , The first volume obtained is numbered as volume 1, and then the numbers are increased in order of obtaining, for example, the obtained second weight is coded as weight 2, the third obtained weight is coded as weight 3, and the obtained second weight is coded as weight 3. The volume number is volume 2, where the data with the same number is the data of the same object to be inspected, for example, the volume numbered as volume 5, the barcode numbered as barcode 5, and the weight numbered as weight 5 is the data of the same object to be inspected. .

In a possible implementation manner, the processor 113 and the controller 104 may be the same device, for example, the method corresponding to the processor may be executed by the controller, or may be different devices, such as the processor 113 and the controller. 104 are two independent devices that execute their corresponding methods respectively.

The controller 104 and the processor 113 in this application may be general-purpose processors, including CPU (Central Processing Unit, central processing unit), NP (Network Processor, network processor), etc.; they may also be DSP (Digital Signal Processor, digital Signal processor), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc.

It can be seen that when data is collected through the solution of the embodiment of the present application, the obtained barcode, volume, weight and other information of the object to be detected can be correlated; and the abnormal object obtained by the judgment can be processed by the abnormal handling conveyor belt. Thereby, the acquisition of the information of the object to be detected can be ensured, and the reliability and automation of the system can be improved.

Referring to FIG. 9c, when the tail of the short object 200 leaves the second sensor 103, the collection of the barcode and volume information of the short object 200 ends, and the next object can enter the first weighing conveyor belt 102. Referring to FIG. 9d, when the head of the short object 200 is detected by the first sensor 105, the weight of the short object 200 detected by the first weighing conveyor belt 102 or the second weighing conveyor belt 103 is acquired.

Referring to FIG. 10c, when the head of the long object 201 is detected by the first sensor 105, the weight of the long object 201 detected by the first weighing conveyor belt 102 and the second weighing conveyor belt 103 is acquired. Referring to FIG. 10d, when the tail of the long object 201 leaves the second sensor 108, the collection of the barcode and volume information of the long object 201 ends, and the next object can enter the first weighing conveyor 102.
