[0032] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the following further details the present application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0033] It should be noted that although the functional modules are divided in the device schematic diagram and the logical sequence is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from the module division in the device or the sequence in the flowchart. Terms such as "first" and "second" in the specification, claims and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.
[0035] A unit mobile container equipment for transporting and storing materials, which generally installs four casters on the loaded acquisition loaded vehicle, is commonly used for logistics distribution or logistics turnover between factory processes. The wheels are usually designed as two fixed-direction wheels.
[0036] In industries such as logistics and warehousing, the loading of goods onto the loaded vehicle is usually completed by the personnel in the operation area. At present, the evaluation of the loading rate of the loaded vehicle is visually completed by the staff. An excessively low loading rate will result in low handling efficiency, the need to purchase more loaded vehicles, and an increase in the operating costs of the enterprise. An excessively high loading rate will cause the goods to pile up too high, resulting in goods backlog and damage, the goods falling off the loaded vehicle, or the loaded vehicle tipping over, etc., which are likely to cause goods losses and personal safety accidents. Therefore, detecting the loading rate of the loaded vehicle can directly improve the utilization efficiency of the loaded vehicle, reduce the goods damage rate, and ensure personal safety. In the related art, in order to achieve the detection of the loading rate of the loaded vehicle, the loading rate of the loaded vehicle is detected by means of visual AI / lidar, etc. Although the cost is high, the accuracy of measuring the loading rate is low, and there are high requirements for the site environment. For example, the camera is blocked by the loaded vehicle, affecting the accuracy of the loading rate detection.
[0037] Based on this, the embodiments of the present application provide a cargo loading state detection device and a cargo hold system, aiming to set a rotating turntable above the loading vehicle, and set a ranging module on the turntable to detect the distance between the turntable and the cargo in the loading vehicle or the ground. The ranging module collects ranging data that reflects the loading rate of the loading vehicle. The processor determines the current cargo loading state of the loading vehicle according to the ranging data and a preset distance range, and sets an indicating module to display the cargo loading state, so as to automatically and accurately identify the loading rate of the loading vehicle and reduce the detection cost.
[0038] The cargo loading state detection device and the cargo hold system provided by the embodiments of the present application are specifically described through the following embodiments. First, the cargo loading state detection device in the embodiments of the present application is described.
[0039] As Figure 1 and Figure 2As shown in the figure, this embodiment discloses a cargo loading state detection device, which is applied to the loading state detection in a loading vehicle, and the loading state is used to characterize the loading rate of the loading vehicle 201, so as to realize the automatic identification of the vehicle loading rate and save manpower. A cargo loading state detection device includes: a turntable 101, a driving module 102, a ranging module 103, a processor 104, and an indicating module 107. The turntable 101 is arranged above the loading vehicle 201, and the driving module 102 is arranged on the turntable 101 and is used to drive the turntable 101 to rotate; the ranging module 103 is arranged on the turntable 101 and is used to measure the distance between the cargo or the ground in the loading vehicle 201 to obtain ranging data; the processor 104 is electrically connected to the driving module 102 and the ranging module 103, and is used to receive the ranging data fed back by the ranging module 103, determine the cargo loading state according to the ranging data and a preset distance range, and output a loading state indication signal according to the cargo loading state. The processor 104 is also used to output a driving signal to the driving module 102 to make the driving module 102 drive the turntable 101 to rotate; the indicating module 107 is electrically connected to the processor 104 and is used to receive the loading state indication signal and perform corresponding loading state indication operations according to the loading state indication signal. Therefore, when the loading vehicle 201 is transported under the turntable 101, the processor 104 sends a driving signal to the driving module 102, and the driving module 102 drives the turntable 101 to rotate, and at the same time drives the ranging module 103 to rotate to measure the distance between the cargo in the loading vehicle 201 to obtain ranging data. The processor 104 compares the ranging data with the preset distance range to determine the cargo loading state of the loading vehicle 201, and sends a loading state indication signal to the indicating module 107 according to the cargo loading state, so that the indicating module 107 performs corresponding loading indication operations according to the loading state indication signal. Therefore, the staff can perform different loading state indication operations through the indicating module 107 to determine the loading rate of the loading vehicle 201, realize the automatic identification of the loading rate of the loading vehicle 201, reduce manpower, only need to set the ranging module 103, the processor 104, the turntable 101 and the driving module 102, without setting devices with high hardware costs such as cameras, and save the detection cost.
[0040] In some embodiments, the ranging data includes multiple measured distance values. It should be noted that the diameter of the turntable 101 is smaller than the diameter of the loading vehicle 201. Therefore, when the turntable 101 rotates, the ranging module 103 measures the distances between multiple cargos in the loading vehicle 201 on the turntable 101 to obtain multiple measured distance values. It should be noted that when the turntable 101 rotates, the ranging module 103 collects multiple measured distance values according to a preset time period. For example Figure 1As shown, the loading vehicle 201 is a cage truck. The cage truck has a relatively high height and can hold multiple goods, and the positions of the goods are irregular. Therefore, collecting only one distance cannot accurately represent the loading rate in the cage truck. In this embodiment, multiple measurement distance values are obtained by collecting the distances between the ranging module 103 and multiple goods, and the average value of the multiple measurement distance values is calculated as the target distance value, which can more accurately represent the loading rate in the cage truck. By comparing the target distance value with a preset distance range, and the preset distance range is set according to the same type of loading vehicle 201, so as to make the detection of the loading state of loading vehicles 201 with different loading heights more accurate. Specifically, if the target distance value is greater than the upper limit value of the preset distance range, it is determined that the goods loading state is an overloading state, and the overloading state indicates that there are too many goods in the cage truck and the loading rate is too high. If the target distance value is less than the lower limit value of the preset distance range, it is determined that the goods loading rate state is an underloading state, and the underloading state indicates that there are too few goods in the cage truck and the loading rate is too low. If the target distance value is within the preset distance range, it is determined that the goods loading state is a qualified loading state, and the qualified loading state indicates that the goods in the cage truck are appropriate. Therefore, by collecting N measurement distance values, then calculating the average value of the N measurement distance values as the target distance value, and then comparing the target distance value with the preset distance range to determine the goods loading state, the automatic and accurate detection of the loading rate of the cage truck is realized.
[0041] In some embodiments, the processor 104 is further configured to compare the target distance value with a preset ground distance value to obtain the current vehicle state of the loading vehicle 201, and output a vehicle indication signal according to the current vehicle state. The indication module 107 is further configured to perform a corresponding vehicle state indication operation according to the vehicle indication signal. It should be noted that the goods loading state detection device provided in this embodiment can not only realize the detection of the goods loading state, but also further detect whether there is a loading vehicle 201 under the turntable 101. Only by comparing the target distance value with the ground distance value to determine whether the loading vehicle 201 is under the turntable 101, and performing a corresponding vehicle state indication operation, so that the staff can determine whether the vehicle is under the turntable 101 through the vehicle state indication operation made by the indication module 107, so as to arrange other loading vehicles 201 to move under the turntable 101 for loading rate detection in the case of no loading vehicle 201.
[0042] Specifically, the ground distance value is the distance between the ranging module 103 and the ground. If the target distance value is equal to the ground distance value, or the error between the target distance value and the ground distance value is within the error range, it is determined that the current vehicle state is the vehicle removed state, and the vehicle removed state indicates that there is no loaded vehicle 201 under the turntable 101; if the target distance value is less than the ground distance value, it is determined that the current vehicle state is the vehicle stopped state, and the vehicle stopped state indicates that there is a loaded vehicle 201 under the turntable 101. Therefore, by comparing the magnitudes of the target distance value and the ground distance value, it can be determined whether there is a loaded vehicle 201 under the turntable 101, so as to perform different indication operations, which is convenient for the staff to arrange other loaded vehicles 201 for loading state detection.
[0043] In some embodiments, the ranging module 103 is any one of an ultrasonic ranging module 103, an infrared ranging module 103, a laser ranging module 103, and a radar ranging module 103, and no specific limitation is made in this embodiment. For example, if the ranging module 103 is an ultrasonic ranging module 103, the circuit connection structure of the ultrasonic ranging module 103 is as Figure 3 shown, as Figure 3 can be seen, the ultrasonic ranging module 103 includes: an ultrasonic ranging chip and a first capacitor, and one end of the first capacitor is connected to the fifth pin of the ultrasonic ranging chip, and the other end is connected to the sixth pin of the ultrasonic ranging chip.
[0044] In some embodiments, the cargo loading state detection device further includes: a power supply module 105, which is electrically connected to the processor 104 and is used to convert the mains voltage into a target voltage and provide the target voltage to the processor 104. By setting the power supply module 105 to convert the mains voltage into a target voltage suitable for the processor 104, the processor 104 can be normally started, and then drive the ranging module 103, the driving module 102, and the indication module 107 to start. As Figure 4 shown, the power supply module 105 can convert the mains voltage into target voltages of two voltage values, which are converting 220V voltage into 3.3V, or converting 220V voltage into 5V, to meet the voltage requirements of different modules.
[0045] In some embodiments, the cargo loading state detection device further includes: a wireless transmission module 106, which is electrically connected to the processor 104 and is configured to generate cargo loading state detection data according to the cargo loading state and send the cargo loading state detection data to the background monitoring device 108. The cargo loading state detection data of each loading vehicle 201 is generated through the wireless transmission module 106 and sent to the background monitoring device 108. The staff of the background monitoring device 108 can remotely know the loading rate of each loading vehicle 201 without being in the area where the loading vehicle 201 is located, so as to facilitate the quantitative management of cargo loading and provide data for the rectification in the cargo warehouse.
[0046] In some embodiments, the wireless transmission module 106 includes any one of the following: a Bluetooth module, a GPRS module, a WIFI module, a LoRa module, and a ZigBee module. However, the present embodiment does not specifically limit the wireless transmission module 106. For example, the wireless transmission module 106 is a WI FI module, and the connection structure of the WI FI module is as Figure 5 shown. Through Figure 5 it can be seen that the WI FI module is connected to the processor 104 through the RXD pin, the TXD pin, the SET pin, and the CS pin to transmit the converted data of the cargo loading state to the background monitoring device 108.
[0047] In some embodiments, the indication module 107 includes a multi-color alarm light, which is electrically connected to the processor 104 and displays yellow according to the loading state indication signal when the cargo loading rate is in an overloaded state, and displays red according to the loading state indication signal when the cargo loading state is in an underloaded state. Therefore, the overloaded state is indicated by the multi-color alarm light showing yellow, and the underloaded state is indicated by the multi-color alarm light showing red, so that the staff can determine the cargo loading state only through the color shown by the multi-color alarm light, which is convenient for making different management of the loading vehicle 201 and reducing the occurrence of cargo losses and personal safety accidents caused by the falling of goods or the tipping over of the loading vehicle 201.
[0048] It should be noted that if the cargo loading state is a qualified loading state, the multi-color alarm light displays green, indicating that the cargo volume of the current loading vehicle 201 is appropriate and there is no need to adjust the loading vehicle 201.
[0049] Specifically, the connection structure of the processor 104 and the multi-color alarm light is as Figure 6As shown, two multi-color warning lights are provided and are respectively defined as the first multi-color light and the second multi-color light. One end of the first multi-color light is connected to one end of the second resistor, and the other end is grounded. The other end of the second resistor is connected to the processor 104. One end of the second multi-color light is connected to one end of the third resistor, and the other end is grounded. The other end of the third resistor is connected to the processor 104. Therefore, only two multi-color warning lights are set to display the cargo loading status, which is not only convenient for the staff to view, but also does not require high-cost devices such as cameras and monitors, saving the cost of displaying the cargo loading status.
[0050] In some embodiments, the driving module 102 is a motor driving circuit, and the connection of the motor driving circuit is as Figure 7 shown. Through Figure 7 it can be seen that the motor driving circuit includes a motor driving chip and a motor wiring harness socket, and the motor driving chip is connected to the processor 104 through the first pin to the fifth pin, so as to receive the driving signal sent by the processor 104 and drive the turntable 101 to rotate.
[0051] It should be noted that the power supply module 105, the wireless transmission module 106 and the processor 104 are integrated on a printed circuit board, and the printed circuit board is arranged inside the turntable 101.
[0052] The embodiment of the present application also provides a warehouse system, which includes a plurality of loading vehicles 201 and a cargo loading status detection device; wherein, the composition and function of the cargo loading status detection device are the same as those of the above-mentioned cargo loading status detection device, and will not be elaborated here. Specifically, the cargo loading status detection device is used to detect the cargo loading status in the loading vehicle located in the detection area and make different loading indication operations according to the cargo loading status. Therefore, by constructing a warehouse system including a plurality of loading vehicles 201 and a cargo loading status detection device, the automatic detection of the cargo loading status in the loading vehicle 201 is realized, without too much manual participation, and an unmanned warehouse system is realized.
[0053] In some embodiments, the warehouse system further includes: a background monitoring device 108, which communicates wirelessly with the cargo loading status detection device and receives the cargo loading status detection data fed back by the cargo loading status detection device based on the cargo loading status. It should be noted that the loading vehicle 201 is a cage truck. By remotely connecting to the background monitoring device 108, the staff can view the loading rate of the cage truck without having to reach the factory area where the cage truck is located. At the same time, the cargo loading status detection data can be stored through the background monitoring device 108, which is beneficial to subsequent quantitative management of the warehouse system and provides data for the renovation of the warehouse system.
