Technical Field

[0001] The present invention relates to the field of transportation technology, and in particular to a box assembly, a vehicle, and a box status detection method. Background Art

[0002] As grain trade continues, process and digital oversight undoubtedly provide powerful persuasiveness and security for bulk finance. However, current container anti-theft devices on the market cannot monitor the status of the container and can only passively prevent grain loss. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, one aspect of the present invention is to provide a box assembly.

[0005] Another aspect of the present invention is to provide a vehicle.

[0006] Another aspect of the present invention is to provide a method for detecting the status of a box.

[0007] In view of this, according to one aspect of the present invention, a box assembly is proposed, including: a box body, the box body is provided with an opening, and a box door is provided at the opening; a baffle structure, arranged at the opening, the baffle structure is used to block the opening, and the box door is provided on the outside of the baffle structure; a pressure sensor, arranged on the baffle structure, the pressure sensor is used to detect the pressure information of the box body; a locator, arranged on the baffle structure, the locator is used to obtain positioning information; a controller, respectively connected to the pressure sensor and the locator, the controller is used to determine the box body status information in response to the pressure information and the positioning information.

[0008] The box assembly provided by the present invention includes a box, a baffle structure, a pressure sensor and a locator arranged on the baffle structure, and a controller connected to the pressure sensor and the locator. The box is provided with an opening, a box door is provided at the opening, the baffle structure is provided at the opening of the box, and a box door is provided on the outside of the baffle structure. The opening is blocked by the baffle structure, and after the box is fully loaded with goods, the pressure information of the goods and the box door acting together on the baffle structure is detected by the pressure sensor, and the box is positioned by the locator. The controller combines the pressure information and positioning information to analyze and alarm the abnormal movement and stop of the goods during transportation, and the abnormal pressure value changes, thereby judging the state of the box, timely locating and knowing the loss of goods, and then assigning the responsibility for the loss to the person, and establishing a complete box freight supervision system.

[0009] Among them, the pressure sensor, positioner and controller are all installed on the baffle structure. On the one hand, the baffle structure has the functionality of preventing grain loss and monitoring the status of the box. On the other hand, it simplifies the installation structure of the box components, avoids further modification of the box, and also facilitates the maintenance of each sensor.

[0010] Specifically, the controller can report the positioning information and the pressure information on the baffle structure to the server in real time, so that the server can judge the abnormal movement and stop during transportation at any time, thereby being able to monitor the status of the box in a timely and effective manner, and then more effectively manage and prevent the transportation of the box.

[0011] Specifically, the box body can be a container and a container-type truck compartment.

[0012] In addition, the baffle structure is easy to install and can be well promoted and used in business without additional training costs.

[0013] According to the above-mentioned box assembly of the present invention, it can also have the following technical features:

[0014] In the above technical solution, preferably, the baffle structure includes: a first panel, the first panel is used to be inserted into the bottom of the opening; a second panel, the second panel is fixedly connected to the first panel, and a box door is provided on the outer side of the second panel.

[0015] In this technical solution, the baffle structure includes a first panel and a second panel. The first panel is used to be inserted into the bottom of the box opening, the second panel is fixedly connected to the first panel, and a box door is provided on the outside of the second panel. The baffle structure provided by the present invention only needs to insert the first panel of the baffle structure into the bottom of the box opening before loading and transportation, and the baffle structure is fixed to the box with the help of the cargo, thereby realizing the installation of the baffle structure and the box, which is very convenient to use; at the same time, it can ensure that the baffle structure will not fall off automatically, and the opening is sealed by the second panel, so that even when the bottom of the box door is damaged, the pressure fluctuation value can be detected, which can effectively prevent the loss of cargo; at the same time, the baffle structure and the box are relatively independent. It can be understood that as long as the box type matches the baffle structure, the baffle structure is universal between different boxes, making the baffle structure more practical; in addition, since the baffle structure is independent of the box, it is more convenient to maintain.

[0016] Specifically, the first panel and the second panel form an L-shaped baffle structure.

[0017] Furthermore, the L-shaped baffle structure formed by the first panel and the second panel is an integrated baffle structure.

[0018] In addition, the second panel and the first panel can also be connected at a certain angle, and the angle is adjustable.

[0019] In any of the above technical solutions, preferably, the pressure sensor includes: at least one first pressure sensor, at least one first pressure sensor is arranged on one side of the inner side surface of the second panel according to a preset spacing; at least one second pressure sensor, at least one second pressure sensor is arranged in the middle of the inner side surface of the second panel according to a preset spacing; at least one third pressure sensor, at least one third pressure sensor is arranged on the other side of the inner side surface of the second panel according to a preset spacing.

[0020] In this technical solution, the pressure sensors include at least one first pressure sensor, at least one second pressure sensor, and at least one third pressure sensor. The at least one first pressure sensor is disposed at a preset spacing on one side of the inner side of the second panel, the at least one second pressure sensor is disposed at a preset spacing in the middle of the inner side, and the at least one third pressure sensor is disposed at a preset spacing on the other side of the inner side. This allows for more comprehensive monitoring of pressure fluctuations caused by abnormal movement of the box on the baffle structure. Furthermore, based on the pressure change values ​​of the pressure sensors at different positions, combined with positioning information, a comprehensive analysis of the box's status can be performed, enabling more accurate judgment of the box's status, more effective supervision and theft prevention of boxes in transit, and improved box transportation safety.

[0021] Specifically, the preset interval may be determined according to the height or width of the second panel.

[0022] In any of the above technical solutions, preferably, the angle between the first panel and the second panel is 90°; the width of the first panel and the width of the second panel are both equal to the width of the opening.

[0023] In this technical solution, the angle between the first and second panels is 90°, and the width of the first and second panels is equal, i.e., an L-shaped baffle structure. Furthermore, the width of the first and second panels are both equal to the width of the box opening, effectively preventing food from leaking if the box door is damaged.

[0024] In any of the above technical solutions, preferably, the length range of the first panel is: 30cm to 50cm; the height range of the second panel is: 20cm to 80cm; the thickness range of the first panel is: 1cm to 10cm; the thickness range of the second panel is: 1cm to 20cm.

[0025] In this technical solution, the length of the first panel ranges from 30cm to 50cm, but is not limited thereto. The length of the first panel cannot be too short. If it is too short, it will be detrimental to the stability of the baffle structure fixed on the box body, thereby affecting the accuracy of the pressure fluctuation value detection, and it will not be conducive to the baffle structure preventing cargo leakage. At the same time, it does not need to be too long to avoid unnecessary waste of resources.

[0026] The height of the second panel ranges from 20 cm to 80 cm, but is not limited thereto. The height of the second panel only needs to ensure that the baffle structure has both the function of sealing lost goods and the above-mentioned monitoring function.

[0027] The thickness of the first panel ranges from 1 cm to 10 cm, but is not limited thereto. The thickness of the first panel cannot be too thin to avoid deformation.

[0028] The thickness of the second panel ranges from 1 cm to 20 cm, but is not limited thereto. The thickness of the second panel cannot be too thin. On the one hand, deformation can be avoided. On the other hand, the impact of the installation of various sensors and controllers on its thickness must also be considered to improve the reliability of the baffle structure in detection and its service life.

[0029] In any of the above technical solutions, preferably, the box assembly also includes: a vibration sensor, which is arranged on the baffle structure, and is used to detect the vibration information of the box; a controller, which is connected to the vibration sensor, and is used to determine the box status information in response to pressure information, vibration information and positioning information.

[0030] In this technical solution, the box assembly also includes a vibration sensor, which is arranged on the baffle structure and connected to the controller. The vibration sensor detects the vibration information of the box, and the controller judges the abnormal movement of the box in combination with the pressure information, positioning information and vibration information, thereby judging the state of the box, such as whether the box is damaged, including whether the door or baffle structure has been damaged, or is being disassembled, or whether there is a risk of premature unloading, etc. Furthermore, different warnings are given for different detection and analysis results, abnormal positions are locked, and the box transportation capacity, such as basic information of drivers and vehicles, can be sent to the background management center, so as to lock the person in charge of the abnormality, time point, route, etc., to better manage and prevent theft of box transportation and improve the transportation safety of boxes (such as containers).

[0031] Specifically, the controller can report the positioning information, vibration information and pressure information on the baffle structure to the network client in real time, so that the network client can judge the abnormal movement and stop during transportation at any time, thereby being able to monitor the status of the box in a timely and effective manner, and then more effectively manage and prevent the transportation of the box.

[0032] In any of the above technical solutions, preferably, the vibration sensor is arranged on the inner side surface of the second panel.

[0033] In this technical solution, the pressure sensor, locator, vibration sensor and controller are all arranged on the inner side of the second panel. When the box is fully loaded with goods and there is an abnormal movement, such as when the door is removed or the box is tilted, the inner side of the second panel is affected more obviously, so that the abnormal movement information of the box can be detected in a timely and accurate manner.

[0034] In any of the above technical solutions, preferably, the box assembly further includes: a power module connected to the controller, and the power module is used to supply power to the controller.

[0035] In this technical solution, the box assembly also includes a power module, which is connected to the controller so as to supply power to the controller and ensure stable operation of the monitoring function of the box assembly.

[0036] In any of the above technical solutions, preferably, the box assembly further includes: an alarm module connected to the controller for alarming.

[0037] In this technical solution, the box assembly further includes an alarm module, which sounds an alarm in response to an instruction from the controller. Specifically, the alarm module can sound different alarms in response to different instructions.

[0038] According to another aspect of the present invention, a vehicle is provided, comprising a box assembly as described in any of the above technical solutions.

[0039] The vehicle provided by the present invention includes the box assembly as in any of the above technical solutions, and thus the vehicle includes all the beneficial effects of the box assembly of any of the above technical solutions.

[0040] According to another aspect of the present invention, a method for detecting the state of a box is proposed, which is used for the box component of any of the above-mentioned technical solutions. The method includes: obtaining multiple pressure change values, and multiple sensor positions corresponding to the multiple pressure change values; obtaining positioning information; and determining the state of the box based on the multiple pressure change values, and the multiple sensor positions corresponding to the multiple pressure change values ​​and the positioning information.

[0041] The present invention provides a method for detecting the state of a box. During transportation, multiple pressure sensors on the baffle structure collect multiple pressure values ​​of the cargo and the box door acting together on the baffle structure, and each pressure value is subtracted from the corresponding initial value to obtain multiple pressure change values. The positioning information of the box is collected by a locator. Based on the multiple pressure change values ​​and positioning information, abnormal movements and stops of the cargo during transportation and abnormal pressure value changes are analyzed and alarmed, thereby judging the state of the box, timely locating and knowing the loss of cargo, and then assigning responsibility for the loss to individuals, thereby establishing a complete box freight supervision system.

[0042] Among them, after the box door is closed and sealed, the controller records the pressure value of each sensor and regards it as the initial value.

[0043] Specifically, the positioning information and the pressure information on the baffle structure can be obtained in real time, so that the abnormal movement and stop during transportation can be judged at any time, so that the status of the box can be monitored in a timely and effective manner, and the box transportation can be managed and theft-proofed more effectively.

[0044] Specifically, the box body can be a container and a container-type truck compartment.

[0045] In any of the above technical solutions, preferably, the step of determining the state of the box based on multiple pressure change values, and multiple sensor positions and positioning information corresponding to the multiple pressure change values ​​specifically includes: when the pressure change value is greater than the preset pressure threshold, the sensor position includes the first preset position and / or the second preset position, and the positioning box is in transit, judging whether the positioning information is abnormal; when the positioning information is judged to be abnormal, determining that the box has been damaged; when the positioning information is judged to be normal, judging whether the pressure change value fluctuates within a preset range; when the pressure change value is judged to fluctuate within the preset range, and it is determined that the current road condition is a sharp bend or an uphill or downhill road, determining that the state of the box is normal; when the pressure change value is greater than the preset pressure threshold, the sensor position is the first preset position and / or the second preset position, and the positioning box is at the destination, determining that the state of the box is normal.

[0046] In this technical solution, multiple pressure change values ​​corresponding to multiple pressure sensors are obtained in real time or at a certain time interval to obtain positioning information; when more than two pressure change values ​​are greater than a preset pressure threshold, the position of the pressure sensor is first determined, and the position of the box is located at the same time; when the sensor position is at the first preset position and / or the second preset position of the baffle structure, and the positioning box is in transit, it is further determined whether the positioning information is abnormal, such as whether the positioning information has a track within the preset time period, or whether the track deviates from the driving route, etc.; when it is determined that the positioning information is abnormal, it is determined that the box has been damaged and the goods are at risk of being stolen; when it is determined that the positioning information is not abnormal, it is further determined whether the pressure change value fluctuates within a preset range. If the judgment result is yes, it is further determined whether the current road condition is a sharp bend or an uphill or downhill road. If the current road condition is a sharp bend or a relatively steep slope, it is regarded as a pressure change caused by a sharp bend or a relatively steep slope, and the status of the box is normal. At this time, the abnormal information can be recorded and reported to the background management center, but no theft risk warning is issued.

[0047] When the pressure change value is greater than the preset pressure threshold, and the sensor position is the first preset position and / or the second preset position, and the positioning box is at the destination, it is considered that the box is unloaded normally and the status of the box is normal.

[0048] Through the box status detection method of the present invention, abnormal pressure values ​​and GPS positioning information can be promptly transmitted back at any time. At the same time, the abnormal movement and stay of the box can be analyzed and warned in combination with the sensor position information. It can timely and accurately monitor the status of the box, timely locate and know the loss of goods, and then assign the responsibility for the loss to the person, thereby establishing a complete box freight supervision system.

[0049] The absolute value of the preset pressure threshold is greater than or equal to 100 kPa and less than or equal to 250 kPa.

[0050] The first preset position and the second preset position respectively correspond to the position of any first pressure sensor of at least one first pressure sensor set on one side of the inner side surface of the second panel of the baffle structure, and the position of any third pressure sensor of at least one third pressure sensor set on the other side.

[0051] In any of the above technical solutions, preferably, the step of determining the state of the box based on multiple pressure change values, and multiple sensor positions corresponding to the multiple pressure change values ​​and positioning information specifically also includes: when the sensor position includes the first preset position and the third preset position, or the second preset position and the third preset position, and the positioning box is in transit, judging whether the positioning information is abnormal; when it is judged that the positioning information is abnormal, determining that the box is being disassembled.

[0052] In this technical solution, when the sensor position includes the first preset position and the third preset position, or the sensor position includes the second preset position and the third preset position, and the positioning box is in transit, and if the positioning information is determined to be abnormal, it is considered that the box is being damaged, the door or baffle structure may be disassembled, and the cargo may be stolen, and an early warning is issued. The box status detection method of the present invention can more accurately analyze the damage to the box, so that the cargo loss can be located and known in a timely manner, and the loss responsibility can be assigned to the person, thereby establishing a complete box freight supervision system.

[0053] In any of the above technical solutions, the box assembly includes a vibration sensor, and the method also includes: when the pressure change value is greater than a preset pressure threshold and the positioning box is in transit, obtaining a vibration value; judging whether the vibration value is greater than a preset vibration threshold; when the judgment result is yes, determining that the box is being disassembled; otherwise, determining that the state of the box is normal; when the pressure change value is greater than the preset pressure threshold and the positioning box is at the place of origin, determining that the state of the box is normal.

[0054] In this technical solution, when only one pressure change value is greater than a preset pressure threshold and the positioning box is in transit, a vibration value is obtained by a vibration sensor installed on the baffle structure. This vibration value is compared with the preset vibration threshold to determine whether the vibration value exceeds the normal range. If the vibration value exceeds the normal range, the box is considered to be being disassembled. If the vibration value does not exceed the normal range, the box is considered to be in a normal state. Through the technical solution of the present invention, different monitoring schemes are adopted for different pressure fluctuation values ​​in different situations, thereby enabling more comprehensive monitoring of the box state.

[0055] Additional aspects and advantages of the invention will become apparent from the description which follows, or may be learned by practice of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0069] The following combination Figures 1 to 8 The present invention describes a box assembly, a vehicle, and a box status detection method according to an embodiment of the present application.

[0070] Example 1:

[0071] like Figures 1 to 3 As shown, the box assembly 1 according to some embodiments of the present invention includes: a box, the box is provided with an opening, and a box door is provided at the opening; a baffle structure 10 is provided at the opening, the baffle structure 10 is used to seal the opening, and the box door is provided on the outside of the baffle structure; a pressure sensor 12 is provided on the baffle structure 10, and the pressure sensor 12 is used to detect the pressure information of the box; a locator 14 is provided on the baffle structure 10, and the locator 14 is used to obtain positioning information; a controller 16 is respectively connected to the pressure sensor 12 and the locator 14, and the controller 16 is used to determine the box status information in response to the pressure information and the positioning information.

[0072] The box assembly 1 provided in this embodiment includes a box, a baffle structure 10, a pressure sensor 12 and a locator 14 provided on the baffle structure 10, and a controller 16 connected to the pressure sensor 12 and the locator 14. The box is provided with an opening, a box door is provided at the opening, the baffle structure 10 is provided at the opening of the box, and a box door is provided on the outside of the baffle structure 10. The opening is blocked by the baffle structure 10, and after the box is fully loaded with goods, the pressure information of the goods and the box door acting on the baffle structure 10 is detected by the pressure sensor 12, and the box is positioned by the locator 14. The controller 16 combines the pressure information and the positioning information to analyze and alarm the abnormal movement and stay of the goods during transportation, and the abnormal pressure value changes, thereby judging the state of the box, timely locating and knowing the loss of goods, and then assigning the responsibility for the loss to the person, thereby establishing a complete box freight supervision system.

[0073] Among them, the pressure sensor 12, the positioner 14 and the controller 16 are all installed on the baffle structure 10. On the one hand, the baffle structure 10 has the functionality of preventing food loss and monitoring the status of the box. On the other hand, it simplifies the installation structure of the box assembly 1, avoiding further modification of the box, and also facilitates the maintenance of the sensors and controller 16 on the baffle structure 10.

[0074] Specifically, if Figure 1 and Figure 2As shown, the controller 16 is an MCU controller. The controller 16 can report the positioning information and the pressure information on the baffle structure 10 to the network client in real time, so that the network client can judge the abnormal movement and stop during the transportation process at any time, thereby being able to timely and effectively monitor the status of the box, and then more effectively manage and prevent the transportation of the box.

[0075] Specifically, the box body can be a container and a container-type truck compartment.

[0076] In addition, the baffle structure 10 is easy to install and can be well promoted and used in business without requiring additional training costs.

[0077] Example 2:

[0078] In the above embodiment, if Figure 1 As shown, the baffle structure 10 includes: a first panel 102, which is used to be inserted into the bottom of the opening; a second panel 104, which is fixedly connected to the first panel 102, and a box door is provided on the outer side of the second panel 104.

[0079] In this embodiment, the baffle structure 10 includes a first panel 102 and a second panel 104. The first panel 102 is inserted into the bottom of the box opening, and the second panel 104 is fixedly connected to the first panel 102. A box door is provided on the outer side of the second panel 104. The baffle structure 10 provided by the present invention can be easily installed by simply inserting the first panel 102 of the baffle structure 10 into the bottom of the box opening before loading and transporting. The baffle structure 10 is then fixed to the box with the aid of the cargo, thereby achieving the installation of the baffle structure 10 and the box, which is very convenient to use. At the same time, the baffle structure 10 is prevented from falling automatically. The second panel 104 seals the opening. Even if the bottom of the box door is damaged, the pressure fluctuation value can be detected, effectively preventing the loss of cargo. At the same time, the baffle structure 10 is relatively independent from the box. As can be understood, as long as the box type matches the baffle structure 10, the baffle structure 10 is universal between different boxes, making the baffle structure 10 more practical. In addition, because the baffle structure 10 is independent of the box, it is more convenient to maintain.

[0080] Specifically, the angle between the first panel 102 and the second panel 104 ranges from 0° to 180°.

[0081] Specifically, the first panel 102 and the second panel 104 form an L-shaped baffle structure.

[0082] Furthermore, the L-shaped baffle structure formed by the first panel 102 and the second panel 104 is an integrated baffle structure.

[0083] Specifically, the second panel 104 and the first panel 102 may also be connected at a certain angle, and the angle is adjustable.

[0084] Example 3:

[0085] In any of the above embodiments, the pressure sensor 12 includes: at least one first pressure sensor 122, at least one first pressure sensor 122 is arranged on one side of the inner side surface of the second panel 104 according to a preset spacing; at least one second pressure sensor 124, at least one second pressure sensor 124 is arranged in the middle of the inner side surface of the second panel 104 according to a preset spacing; at least one third pressure sensor 126, at least one third pressure sensor 126 is arranged on the other side of the inner side surface of the second panel 104 according to a preset spacing.

[0086] In this embodiment, the pressure sensor 12 includes at least one first pressure sensor 122, at least one second pressure sensor 124, and at least one third pressure sensor 126. The at least one first pressure sensor 122 is arranged at a preset interval on one side of the inner side surface of the second panel 104, the at least one second pressure sensor 124 is arranged at a preset interval in the middle of the inner side surface, and the at least one third pressure sensor 126 is arranged at a preset interval on the other side of the inner side surface. This allows for more comprehensive monitoring of pressure fluctuations on the baffle structure 10 caused by abnormal movement of the box. Furthermore, based on the pressure change values ​​of the pressure sensors at different positions, combined with positioning information, a comprehensive analysis of the box status can be performed, enabling more accurate judgment of the box status, more effective supervision and theft prevention of the box in transit, and improved box transportation safety.

[0087] Specifically, the preset interval may be determined according to the height or width of the second panel 104 .

[0088] Specifically, if Figure 1 As shown, the pressure sensor 12 includes: a first pressure sensor 122, which is arranged on one side of the inner side of the second panel 104; a second pressure sensor 124, which is arranged in the middle of the inner side of the second panel 104; and a third pressure sensor 126, which is arranged on the other side of the inner side of the second panel 104.

[0089] Specifically, a plurality of pressure sensors of the same number are provided on both sides of the inner side of the second panel 104 , with a pressure sensor provided every 10 cm. A pressure sensor is provided in the middle of the inner side of the second panel 104 .

[0090] Example 4:

[0091] In any of the above embodiments, if Figure 1As shown, the angle between the first panel 102 and the second panel 104 is 90°; the width of the first panel 102 and the width of the second panel 104 are both equal to the width of the opening.

[0092] In this embodiment, the angle between the first panel 102 and the second panel 104 is 90°, and the width of the first panel 102 is equal to the width of the second panel 104, i.e., an L-shaped baffle structure. Furthermore, the width of the first panel 102 and the width of the second panel 104 are both equal to the width of the box opening, thereby effectively preventing food from leaking when the box door is damaged.

[0093] Embodiment 5:

[0094] In any of the above embodiments, the length of the first panel 102 ranges from 30 cm to 50 cm; the height of the second panel 104 ranges from 20 cm to 80 cm; the thickness of the first panel 102 ranges from 1 cm to 10 cm; and the thickness of the second panel 104 ranges from 1 cm to 20 cm.

[0095] In this embodiment, the length of the first panel 102 ranges from 30 cm to 50 cm, but is not limited thereto. The length of the first panel 102 cannot be too short. If it is too short, it will be detrimental to the stability of the baffle structure 10 fixed on the box body, thereby affecting the accuracy of the pressure fluctuation value detection, and it will not be conducive to the baffle structure 10 preventing cargo loss. At the same time, it does not need to be too long to avoid unnecessary waste of resources.

[0096] Specifically, the length of the first panel 102 can be 30 cm, 40 cm, 45 cm, etc.

[0097] The height of the second panel 104 ranges from 20 cm to 80 cm, but is not limited thereto. The height of the second panel 104 only needs to ensure that the baffle structure 10 has both the function of blocking lost goods and the above-mentioned monitoring function.

[0105] In this embodiment, the box assembly 1 also includes a vibration sensor 18, which is arranged on the baffle structure 10 and connected to the controller 16. The vibration sensor 18 detects the vibration information of the box, and the controller 16 judges the abnormal movement of the box in combination with the pressure information, positioning information and vibration information, thereby judging the status of the box, such as whether the box is damaged, including whether the door or baffle structure has been damaged, or is being disassembled, or whether there is a risk of premature unloading, etc. Furthermore, different warnings are given for different detection and analysis results, abnormal positions are locked, and the box transportation capacity, such as basic information of drivers and vehicles, can be sent to the background management center, so as to lock the person in charge of the abnormality, time point, route, etc., to better manage and prevent theft of box transportation, and improve the transportation safety of boxes (such as containers).

[0106] Specifically, the controller 16 can report the positioning information, vibration information and pressure information on the baffle structure to the network client in real time, so that the network client can judge the abnormal movement and stop during the transportation process at any time, thereby being able to monitor the status of the box in a timely and effective manner, and then more effectively manage and prevent the transportation of the box.

[0120] Example 11:

[0121] Figure 5 This is one of the flow charts of a method for detecting the state of a box according to an embodiment of the present application. The method for detecting the state of a box includes:

[0122] Step 402: Acquire multiple pressure change values ​​and multiple sensor positions corresponding to the multiple pressure change values;

[0123] Step 404: obtaining positioning information;

[0124] Step 406 : determining the state of the box according to the multiple pressure change values, the multiple sensor positions corresponding to the multiple pressure change values, and the positioning information.

[0125] The present embodiment provides a method for detecting the state of a box. During transportation, multiple pressure sensors on the baffle structure collect multiple pressure values ​​of the cargo and the box door acting on the baffle structure, and each pressure value is subtracted from the corresponding initial value to obtain multiple pressure change values. The positioning information of the box is collected by a locator. Based on the multiple pressure change values ​​and positioning information, abnormal movements and stops of the cargo during transportation, as well as abnormal pressure value changes, are analyzed and alarmed, thereby determining the state of the box, locating and knowing cargo losses in a timely manner, and then assigning responsibility for the losses to individuals, thereby establishing a complete box freight supervision system.

[0126] Among them, after the box door is closed and sealed, the controller records the pressure value of each sensor and regards it as the initial value.

[0127] Specifically, the positioning information and the pressure information on the baffle structure can be obtained in real time, so that the abnormal movement and stop during transportation can be judged at any time, so that the status of the box can be monitored in a timely and effective manner, and the box transportation can be managed and theft-proofed more effectively.

[0128] Specifically, the box body can be a container and a container-type truck compartment.

[0129] Example 12:

[0130] Figure 6 This is the second flow chart of a method for detecting the state of a box according to an embodiment of the present application. The method for detecting the state of the box includes:

[0131] Step 502: Acquire multiple pressure change values ​​and multiple sensor positions corresponding to the multiple pressure change values;

[0132] Step 504: obtaining positioning information;

[0133] Step 506: When the pressure change value is greater than the preset pressure threshold, determine that the sensor position includes the first preset position and / or the second preset position, and the positioning box is in transit;

[0134] Step 508, determine whether the positioning information is abnormal; if the judgment result is yes, execute step 510, if the judgment result is no, execute step 512;

[0135] Step 510: Determine that the box has been damaged and issue a corresponding warning message;

[0136] Step 512, determining whether the pressure change value fluctuates within a preset range; if the determination result is yes, proceed to step 514; if the determination result is no, proceed to step 516;

[0137] Step 514: When it is determined that the current road condition is a sharp curve or an uphill or downhill road, the state of the box is determined to be normal;

[0138] Step 516: It is considered that the box component sensor is faulty and a corresponding warning message is issued.

[0139] In this embodiment, multiple pressure change values ​​corresponding to multiple pressure sensors are obtained in real time or at a certain time interval to obtain positioning information; when more than two pressure change values ​​are greater than a preset pressure threshold, the position of the pressure sensor is first determined, and the position of the box is located at the same time; when the sensor position is at the first preset position and / or the second preset position of the baffle structure, and the positioning box is in transit, it is further determined whether the positioning information is abnormal, such as whether the positioning information has a track within a preset time period, or whether the track deviates from the driving route, etc.; when it is determined that the positioning information is abnormal, it is determined that the box has been damaged and the goods are at risk of being stolen; when it is determined that the positioning information is not abnormal, it is further determined whether the pressure change value fluctuates within a preset range. If the judgment result is yes, it is further determined whether the current road condition is a sharp bend or an uphill or downhill road. If the current road condition is a sharp bend or a relatively steep slope, it is regarded as a pressure change caused by a sharp bend or a relatively steep slope, and the status of the box is normal. At this time, the abnormal information can be recorded and reported to the background management center, but no theft risk warning is issued.

[0140] Furthermore, when the pressure change value is greater than the preset pressure threshold, and the sensor position is the first preset position and / or the second preset position, and the positioning box is at the destination, it is considered that the box is unloaded normally and the status of the box is normal.

[0141] The box status detection method of this embodiment can timely transmit abnormal pressure values ​​and GPS positioning information at any time, and at the same time analyze and issue early warnings for abnormal box movements and stops in combination with sensor position information. It can timely and accurately monitor the status of the box, timely locate and know about cargo losses, and then assign responsibility for the losses to individuals, thereby establishing a complete box freight supervision system.

[0142] The absolute value of the preset pressure threshold is greater than or equal to 100 kPa and less than or equal to 250 kPa.

[0143] The first preset position and the second preset position respectively correspond to the position of any first pressure sensor of at least one first pressure sensor set on one side of the inner side surface of the second panel of the baffle structure, and the position of any third pressure sensor of at least one third pressure sensor set on the other side.

[0144] Example 13:

[0145] Figure 7 This is the third flow chart of a method for detecting the state of a box according to an embodiment of the present application. The method for detecting the state of a box includes:

[0146] Step 602, obtaining a plurality of pressure change values ​​and a plurality of sensor positions corresponding to the plurality of pressure change values;

[0147] Step 604: Acquire positioning information;

[0148] Step 606: When the pressure change value is greater than the preset pressure threshold, it is determined that the sensor position includes the first preset position and the third preset position, or the sensor position includes the second preset position and the third preset position, and the positioning box is in transit;

[0149] Step 608: Determine whether the positioning information is abnormal;

[0150] Step 610: When it is determined that the positioning information is abnormal, it is determined that the box is being disassembled.

[0151] In this embodiment, when the sensor position includes the first preset position and the third preset position, or the sensor position includes the second preset position and the third preset position, and the container is being transported, and if the positioning information is determined to be abnormal, it is considered that the container is being damaged, the door or baffle structure may be disassembled, and the cargo may be stolen, and an early warning is issued. The container status detection method of the present invention can more accurately analyze the damage to the container, thereby locating and notifying the cargo loss in a timely manner, and then assigning responsibility for the loss to the person, thereby establishing a complete container freight supervision system.

[0152] Example 14:

[0153] Figure 8 This is the fourth flow chart of a method for detecting the state of a box according to an embodiment of the present application. The method for detecting the state of the box includes:

[0154] Step 702: Acquire multiple pressure change values ​​and multiple sensor positions corresponding to the multiple pressure change values;

[0155] Step 704: Acquire positioning information;

[0156] Step 706: When the pressure change value is greater than the preset pressure threshold, the position of the box is located; if the box is located in transit, step 708 is executed; if the box is located at the origin, step 714 is executed;

[0157] Step 708: When the positioning box is in transit, obtain the vibration value;

[0158] Step 710, determine whether the vibration value is greater than a preset vibration threshold; if so, execute step 712;

[0159] Step 712, determining that the box is being disassembled;

[0160] Step 714: When the container is located at the origin, it is determined that the status of the container is normal.

[0161] In this embodiment, when only one pressure change value is greater than the preset pressure threshold and the positioning box is in transit, the vibration value is obtained by the vibration sensor set on the baffle structure, and the vibration value is compared with the preset vibration threshold to determine whether the vibration value exceeds the normal range. If the vibration value exceeds the normal range, it is considered that the box is being disassembled. If the vibration value does not exceed the normal range, it is considered that the state of the box is normal. Through the embodiments of the present invention, different monitoring schemes are adopted for the pressure change values ​​in different situations, so that the state of the box can be monitored more comprehensively. If the vibration value is less than the preset vibration threshold, it is considered that the state of the box is normal.

[0162] Embodiment 15:

[0163] like Figures 1 to 3 As shown, the box assembly 1 of this embodiment includes a container (for transporting grain), a power module 20 including a 3V MCU DC power supply, a baffle structure 10, a pressure sensor 12 installed on the baffle structure 10, a locator 14, a controller 16 and a vibration sensor, wherein the locator 14 is a GPS module, the controller 16 is an MCU controller, and is connected to the public communication network through the TCP / IP protocol to communicate with the background management center.

[0164] The baffle structure 10 is a device specially installed at the bottom of the container door (i.e. the bottom of the container opening) to prevent grain leakage caused by damage to the bottom of the container door body (i.e. the box door).

[0165] Pressure sensors are installed in the middle of both sides of the second panel 104. After the grain is loaded, the baffle structure 10 is installed, and the container door is closed and sealed, the system records the pressure values ​​of each sensor and regards them as initial values. When the values ​​fluctuate by more than 200 kPa during transportation, it is regarded as a possibility of malicious grain damage and an alarm is given.

[0166] A GPS positioning device is installed on the baffle structure 10 to report information on the travel route of the entire container. After the pressure value alarm is issued, combined with the GPS positioning information, if the trajectory pauses or deviates from the normal course 5 minutes before and after the positioning information, an alarm will be given to indicate that the cargo is at risk of being stolen.

[0167] The bottom of the baffle (first panel 102) is mainly used to insert the bottom of the grain at the door of the container. The thickness (T1) of the board is 1cm to 10cm. The material can be set arbitrarily according to actual conditions. The length (L) is 30cm to 50cm, and the width (W) depends on the installation position.

[0168] 1. If it is a rear-door container, it depends on the container type and is the inner width of the container, as shown in Table 1:

[0169] Table 1

[0170]

[0171] 2. If it is a side-door container, as shown in Table 2:

[0177] When the fluctuation range of one of the sensor values ​​is greater than 200kPa:

[0178] (1) If one device experiences an abnormal movement and the other does not, there is no GPS track, and the current location is within 2 km of the origin, it is considered that there may be a sensor abnormality and it is not considered a safe abnormal movement.

[0179] (2) If the GPS has a track and the current location is not at the starting point, and the vehicle is traveling on the road, and the vibration sensor has no abnormal movement, it is considered that the sensor may be abnormal and is not considered a safety abnormality.

[0180] (3) If the GPS has a track and the current location is not at the origin, and the vibration sensor has an abnormal movement, it is considered that there may be a possibility of food theft, and an abnormal movement warning is issued. When the platform receives the abnormal movement warning, it will notify the team leader or platform operator of the abnormal movement, record the vehicle's abnormal movement, and contact the driver to understand the situation.

[0181] When the fluctuation range of two sensors is greater than 200kPa, an early warning is given:

[0182] If two sensors move abnormally, determine the installation positions of the two sensors. If both are on both sides:

[0183] (1) If the GPS positioning is in progress and there is no movement within 2 minutes, it is considered that the baffle is removed or the box is damaged, and an early warning is issued.

[0184] (2) If the GPS positioning is on the way and has been moving for 2 minutes, and the pressure value fluctuates up and down within 200 kPa, the GPS needs to accurately determine whether the current road is on a curve, downhill or uphill road. If so, it is considered a sharp curve. The pressure changes caused by the steep ups and downslopes are recorded and reported to the team leader and platform administrator, but no food theft risk warning is issued.

[0185] (3) If the GPS is positioned at the destination, it is considered a normal unloading and no warning is required.

[0186] If two sensors move abnormally, determine the installation positions of the two sensors. If one is on the side and the other is in the middle:

[0194] When the fluctuation range of one of the sensor values ​​is greater than 200kPa:

[0195] (1) If one device experiences an abnormal movement and the other does not, there is no GPS track, and the current location is within 2 km of the origin, it is considered that there may be a sensor abnormality and it is not considered a safe abnormal movement.

[0196] (2) If the GPS has a track and the current location is not at the starting point, and the vehicle is traveling on the road, and the vibration sensor has no abnormal movement, it is considered that the sensor may be abnormal and is not considered a safety abnormality.

[0197] (3) If the GPS has a track and the current location is not at the origin, and the vibration sensor has an abnormal movement, it is considered that there may be a possibility of food theft, and an abnormal movement warning is issued.

[0198] When the fluctuation range of at least two sensors on the side is greater than 200kPa, an early warning is given:

[0199] Determine the installation position of the sensor. If it is on both sides:

[0200] (1) If the GPS positioning is in progress and there is no movement within 2 minutes, it is considered that the baffle is removed or the box is damaged, and an early warning is issued.

[0201] (2) If the GPS positioning is on the way and has been moving for 2 minutes, and the pressure value fluctuates up and down within 200 kPa, the GPS needs to accurately determine whether the current road is on a curve, downhill or uphill road. If so, it is considered a sharp curve. The pressure changes caused by the steep ups and downslopes are recorded and reported to the team leader and platform administrator, but no food theft risk warning is issued.

[0202] (3) If the GPS is positioned at the destination, it is considered a normal unloading and no warning is required.

[0203] Determine the installation position of the sensor. If at least one is in the middle and the others are on both sides:

[0204] (1) If the GPS positioning is in progress and there is no movement within 2 minutes, it is considered that the box or baffle may be disassembled and an early warning is issued.

[0205] (2) If the GPS positioning is on the way and has been moving for 2 minutes, and the pressure value fluctuates up and down within 200 kPa, the GPS needs to accurately determine whether the current road is on a curve, downhill or uphill road.
