Description

Technical Field

[0001] The present invention belongs to the field of logistics security inspection, relates to a pre-security inspection logistics tracking technology, and specifically provides a pre-security inspection logistics tracking system and method. Background Art

[0002] Logistics refers to the process of transporting products from the starting point to the end point of the supply chain, involving multiple links and various modes of transportation. In the logistics process, in order to ensure the safety and smooth delivery of goods, pre-security inspection has become an important link in the logistics industry. Pre-security inspection refers to the process of security inspection and screening of goods in the early stages of entering the logistics chain. The process usually occurs before the goods leave the supplier or manufacturer's location and enter the logistics transportation network. The purpose of pre-security inspection is to identify and eliminate possible security risks. Through pre-security inspection, logistics companies can ensure that goods are screened before entering the logistics chain, thereby reducing security risks.

[0003] Under current technology, flight schedules necessitate that pre-screening be completed some time before departure. However, the inherent characteristics of shipping, along with the volume, weight, and additional requirements of cargo, negatively impact screening efficiency. Consequently, the challenge remains how to optimize and track the progress of pre-screening logistics in real time based on cargo characteristics.

[0004] To this end, we propose a pre-security inspection logistics tracking system and method. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention aims to provide a pre-security inspection logistics tracking system and method.

[0006] The technical problems to be solved by the present invention are:

[0007] How to achieve real-time process tracking and optimization of pre-security logistics based on shipment characteristics.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] In a first aspect, a pre-security inspection logistics tracking system includes an information extraction module, a pre-screening module, an execution terminal, a process tracking module, a process analysis module, a scheduling terminal, and a server;

[0010] The information extraction module is used to obtain the object specification information of the logistics shipment and send it to the pre-screening module and the process analysis module via the server;

[0011] The pre-screening module is used to perform preliminary screening on the logistics shipments in the state of waiting for security inspection, and the pre-screening plan for the logistics shipments obtained through screening is sent to the execution terminal via the server;

[0012] The execution terminal is used to transfer and transport the corresponding logistics goods according to the pre-security inspection plan;

[0013] After the logistics shipment is transferred to the waiting area corresponding to the pre-security inspection plan, the process tracking module is used to monitor the security inspection process of the logistics shipment in real time, and the security inspection process data obtained by monitoring the security inspection area is sent to the process analysis module via the server;

[0014] The process analysis module is used to conduct a comprehensive analysis of the logistics cargo detention situation in the security inspection area, and obtain an estimated detention situation in the security inspection area and send it to the dispatch terminal via the server;

[0015] The dispatching terminal is used to dispatch security inspection resources in each security inspection area.

[0016] Furthermore, the object specification information includes the object weight, object length, object width, object height, fragility coefficient and placement orientation of the logistics shipment;

[0017] Standard specification data includes the security inspection entrance width limit, security inspection entrance height limit and security inspection equipment weight limit;

[0018] Security inspection process data includes the number of shipments awaiting inspection in the security inspection area, the inspection time for each logistics shipment, the number of shipments that passed the security inspection, the number of shipments that failed the security inspection, and the critical time for departure.

[0019] Furthermore, the screening process of the pre-screening module specifically includes:

[0020] Obtain the mass of logistics shipments and compare it with the weight limit of security inspection equipment;

[0021] If the weight of the object is greater than or equal to the weight limit of the security inspection equipment, the pre-security inspection plan for the corresponding logistics shipment is determined to be an unconventional object security inspection;

[0022] If the object's weight is less than the weight limit of the security inspection equipment, obtain the logistics cargo placement orientation and the standard specifications of the security inspection equipment;

[0023] When the orientation of a parcel is restricted, the parcel screening process includes:

[0024] Obtain the length and width of the logistics shipment and compare them with the width limit of the security entrance;

[0025] If both the object length and object width are greater than the security inspection entrance width limit, the pre-screening plan for the corresponding logistics shipment is determined to be an unconventional object security inspection;

[0026] If the value of either the object length or the object width is less than or equal to the security entrance width limit, the height of the logistics shipment is obtained and compared with the security entrance height limit;

[0027] If the height of the object exceeds the height limit of the security check entrance, the pre-security check plan for the corresponding logistics shipment is determined to be an unconventional object security check;

[0028] If the height of the object is less than or equal to the height limit of the security inspection entrance, the pre-security inspection plan for the corresponding logistics shipment is determined to be conventional object security inspection.

[0029] Furthermore, the screening process of the pre-screening module specifically includes:

[0030] When the orientation of the logistics shipment is unrestricted, the logistics shipment screening process specifically includes:

[0031] Obtain the length and width of the logistics shipment and compare them with the width limit of the security entrance;

[0032] If both the object length and object width are greater than the security entrance width limit, the object height is obtained and compared with the security entrance width limit;

[0033] If the height of the object exceeds the width limit of the security inspection entrance, the pre-security inspection plan for the corresponding logistics shipment is determined to be an unconventional object security inspection;

[0034] If the height of the object is less than or equal to the width limit of the security entrance, the length and width of the object will be compared with the height limit of the security entrance respectively;

[0035] If both the object length and object width are greater than the height limit of the security checkpoint entrance, the pre-screening plan for the corresponding logistics shipment is determined to be an unconventional object security check;

[0036] If the value of either the object length or the object width is less than or equal to the height limit of the security check entrance, the pre-screening plan for the corresponding logistics shipment is determined to be regular object security inspection;

[0037] If the value of either the object length or the object width is less than or equal to the security entrance width limit, the height of the logistics shipment is obtained and compared with the security entrance height limit;

[0038] If the height of the object exceeds the height limit of the security check entrance, the pre-security check plan for the corresponding logistics shipment is determined to be an unconventional object security check;

[0039] If the height of the object is less than or equal to the height limit of the security inspection entrance, the pre-security inspection plan for the corresponding logistics shipment is determined to be conventional object security inspection.

[0040] Furthermore, the working process of the execution terminal is specifically as follows:

[0041] If the pre-screening plan for the logistics shipment is conventional object screening, the corresponding objects will be transferred to the waiting area for mechanical security screening;

[0042] If the pre-security inspection plan for the logistics shipment is non-routine object inspection, the corresponding object will be transferred to the waiting area for manual inspection.

[0043] Furthermore, the analysis process of the process analysis module is as follows:

[0044] Obtain the number of parcels that passed security inspection, the number of parcels that failed security inspection, and the number of parcels awaiting security inspection in the security inspection area. Add the number of parcels that passed security inspection and the number of parcels that failed security inspection to calculate the number of parcels inspected. The sum of the number of parcels inspected and the number of parcels awaiting security inspection equals the total number of parcels.

[0045] Obtain the inspection time, object weight, object length, object width, object height, and fragility factor of the inspected items in the security inspection area;

[0046] Calculate the security inspection time coefficient of the inspected shipments, then add up the security inspection time coefficients of each inspected shipment and take the average value to be set as the security inspection time reference coefficient;

[0047] Calculate the estimated inspection time for the goods to be inspected in the inspection area, obtain the critical departure time of the inspection area, and compare the estimated inspection time for the goods to be inspected with the critical departure time;

[0048] If the estimated security inspection time is less than the critical departure time, the estimated detention situation in the corresponding security inspection area is determined to be no shipment detention;

[0049] If the estimated security inspection time is greater than the critical departure time and less than or equal to 1.5 times the critical departure time, the estimated detention situation in the corresponding security inspection area is determined to be a minor cargo detention;

[0050] If the estimated security inspection time is greater than 1.5 times the critical departure time, the estimated detention situation in the corresponding security inspection area is determined to be a heavy cargo detention.

[0051] Furthermore, the module working process of the dispatch terminal is as follows:

[0052] If the estimated detention situation is that there is no shipment detention, no additional security inspection resources will be dispatched;

[0053] If the estimated holdup is minor, additional security inspection resources will be dispatched to the corresponding security inspection area;

[0054] If the estimated detention situation is a heavy cargo detention, additional security inspection resources will be dispatched to the corresponding security inspection area, and staff will be dispatched to conduct manual security inspections.

[0055] In a second aspect, a method for tracking pre-security logistics is provided, wherein the method steps specifically include:

[0056] Step S101: The information extraction module obtains the object specification information of the logistics shipment and sends it to the pre-screening module and the process analysis module;

[0057] In step S102, the pre-screening module performs preliminary screening on the logistics shipments in the security inspection state, and sends the pre-screening plan for the logistics shipments obtained through screening to the execution terminal. The execution terminal transfers the corresponding logistics shipments for transportation according to the pre-screening plan;

[0058] Step S103: After the logistics shipment is transferred to the waiting area corresponding to the pre-security inspection solution, the process tracking module monitors the security inspection process of the logistics shipment in real time and sends the security inspection process data obtained in the security inspection area to the process analysis module;

[0059] In step S104, the process analysis module conducts a comprehensive analysis of the logistics cargo detention situation in the security inspection area, obtains an estimated detention situation in the security inspection area, and sends it to the scheduling terminal, which schedules the security inspection resources of each security inspection area.

[0060] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0061] The present invention first uses the information extraction module to obtain the object specification information of the logistics cargo and sends it to the pre-screening module and the process analysis module, and then uses the pre-screening module to perform preliminary screening on the logistics cargo in the security inspection state, and sends the pre-security inspection plan of the logistics cargo obtained by screening to the execution terminal, and then the execution terminal transfers and transports the corresponding logistics cargo according to the pre-security inspection plan. It also uses the process tracking module to monitor the security inspection process of the logistics cargo in real time, and sends the security inspection process data of the security inspection area obtained by monitoring to the process analysis module, and then the process analysis module conducts a comprehensive analysis of the logistics cargo detention situation in the security inspection area, obtains the estimated detention situation of the security inspection area and sends it to the scheduling terminal, and finally schedules the security inspection resources of each security inspection area through the scheduling terminal. The present invention realizes real-time process tracking and optimization of pre-security inspection logistics. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0069] Example 1:

[0070] See also Figure 1-4 As shown, the technical solution provided by the present invention is: a pre-security inspection logistics tracking system, including an information extraction module, a pre-screening module, an execution terminal, a process tracking module, a process analysis module, a scheduling terminal and a server;

[0071] In this embodiment, the pre-security inspection process is applied to shipping logistics. In actual operation, the pre-security inspection process corresponding to logistics tracking is completed through security inspection equipment equipped at the airport or manual security inspection;

[0072] See also Figure 2 As shown, the information extraction module is used to obtain the object specification information of the logistics shipment and send it to the server. The server sends the object specification data of the logistics shipment to the pre-screening module and the process analysis module. The object specification information includes the object weight, object length, object width, object height, fragility coefficient and placement direction of the logistics shipment, as shown in FIG. Figure 2 As shown, the weight of the logistics shipment is obtained through weighing equipment such as scales or floor scales, and the length, width, and height of the logistics shipment are obtained through measuring equipment. The fragility coefficient reflects the fragility of the corresponding logistics shipment. The larger the value of the fragility coefficient, the more fragile the logistics shipment. The placement orientation specifically indicates whether the placement method of the corresponding logistics shipment is restricted. In actual work, some logistics shipments have the additional requirement of keeping one side facing up at all times. Therefore, the placement method of the corresponding logistics shipment cannot be changed during pre-security inspection and logistics transportation.

[0073] In this embodiment, the pre-screening module is used to perform preliminary screening on the logistics shipments in the state of waiting for security inspection. The screening process is as follows:

[0074] Obtain the mass of logistics shipments and compare it with the weight limit of security inspection equipment;

[0075] If the weight of the object is greater than or equal to the weight limit of the security inspection equipment, the pre-security inspection plan for the corresponding logistics shipment is determined to be an unconventional object security inspection;

[0076] If the object's weight is less than the weight limit of the security inspection equipment, obtain the logistics cargo placement orientation and the standard specifications of the security inspection equipment;

[0077] In this embodiment, the standard specification data includes the security inspection entrance width limit, the security inspection entrance height limit, and the security inspection equipment weight limit. Specifically, the security inspection equipment is equipped with a conveyor. By placing the logistics shipment on the conveyor, the conveyor drives the logistics shipment through the security inspection equipment to complete the pre-security inspection process. Therefore, the logistics shipment must be able to pass through the security inspection entrance and not exceed the weight limit.

[0078] When the orientation of a parcel is restricted, the parcel screening process includes:

[0079] Obtain the length and width of the logistics shipment and compare them with the width limit of the security entrance;

[0080] If both the object length and object width are greater than the security inspection entrance width limit, the pre-screening plan for the corresponding logistics shipment is determined to be an unconventional object security inspection;

[0081] If the value of either the object length or the object width is less than or equal to the security entrance width limit, the height of the logistics shipment is obtained and compared with the security entrance height limit;

[0082] If the height of the object exceeds the height limit of the security check entrance, the pre-security check plan for the corresponding logistics shipment is determined to be an unconventional object security check;

[0083] If the height of the object is less than or equal to the height limit of the security check entrance, the pre-security check plan for the corresponding logistics shipment is determined to be regular object security check;

[0084] See also Figure 3 and Figure 4 As shown in the figure, when the placement direction of the logistics goods is unrestricted, the screening process of the logistics goods specifically includes:

[0085] Obtain the length and width of the logistics shipment and compare them with the width limit of the security entrance;

[0086] like Figure 3 As shown, if the values ​​of the object length and object width are both greater than the security entrance width limit, the object height is obtained and compared with the security entrance width limit;

[0087] If the height of the object exceeds the width limit of the security inspection entrance, the pre-security inspection plan for the corresponding logistics shipment is determined to be an unconventional object security inspection;

[0088] like Figure 4As shown, if the height of the object is less than or equal to the width limit of the security entrance, the length and width of the object are compared with the height limit of the security entrance respectively;

[0089] If both the object length and object width are greater than the height limit of the security checkpoint entrance, the pre-screening plan for the corresponding logistics shipment is determined to be an unconventional object security check;

[0090] If the value of either the object length or the object width is less than or equal to the height limit of the security check entrance, the pre-screening plan for the corresponding logistics shipment is determined to be regular object security inspection;

[0091] If the value of either the object length or the object width is less than or equal to the security entrance width limit, the height of the logistics shipment is obtained and compared with the security entrance height limit;

[0092] If the height of the object exceeds the height limit of the security check entrance, the pre-security check plan for the corresponding logistics shipment is determined to be an unconventional object security check;

[0093] If the height of the object is less than or equal to the height limit of the security check entrance, the pre-security check plan for the corresponding logistics shipment is determined to be regular object security check;

[0094] It is understandable that when there are no restrictions on the placement of logistics shipments, it is necessary to comprehensively consider the impact of various placement methods on the logistics shipment passing through the security checkpoint;

[0095] The pre-screening module sends the pre-security inspection plan for the logistics shipment to the server, and the server sends the pre-security inspection plan for the logistics shipment to the execution terminal;

[0096] The execution terminal transfers the corresponding logistics goods for transportation according to the pre-security inspection plan. The module working process is as follows:

[0097] If the pre-screening plan for the logistics shipment is conventional object screening, the corresponding objects will be transferred to the waiting area for mechanical security screening;

[0098] If the pre-screening plan for the logistics shipment is non-routine item screening, the corresponding items will be transferred to the waiting area for manual screening;

[0099] In this embodiment, mechanical security inspection uses X-ray inspection technology. Due to the limitations of equipment specifications, logistics shipments that cannot pass the security inspection equipment will be manually inspected by staff using inspection equipment;

[0100] As a further solution of this embodiment, after the logistics shipment is transferred to the waiting area corresponding to the pre-security inspection solution, the process tracking module is used to monitor the security inspection process of the logistics shipment in real time. The monitoring process is as follows:

[0101] Obtain security inspection progress data for each security inspection area. This data includes the number of parcels awaiting inspection in the inspection area, the inspection time for each logistics parcel, the number of parcels that passed inspection, the number of parcels that failed inspection, and the critical departure time. The critical departure time is the interval between the current time and the transport vehicle's loading deadline.

[0102] In this embodiment, the transport vehicle for shipping logistics is an airplane, and the loading deadline for the transport vehicle is 45 minutes before the airplane takes off.

[0103] The process tracking module sends the security inspection process data of the security inspection area to the server, and the server sends the security inspection process data of the security inspection area to the process analysis module.

[0104] Specifically, the process analysis module is used to conduct a comprehensive analysis of the logistics shipment detention situation in the security inspection area. The analysis process is as follows:

[0105] Obtain the number of items that passed security inspection TG, the number of items that failed security inspection WG, and the number of items awaiting security inspection DJ in the security inspection area. Add the number of items that passed security inspection and the number of items that failed security inspection to calculate the number of items inspected YJ. It can be understood that the number of items inspected YJ + the number of items awaiting security inspection DJ = the total number of items n;

[0106] Get the inspection time JTi, object weight WZi, object length WCi, object width WKi, object height WGi, and fragility coefficient YSi for the inspected items in the inspection area, where i is the logistics item number and the upper limit of i is n.

[0107] The security inspection time coefficient HSi of the inspected goods is calculated according to the formula. The specific formula is as follows:

[0108]

[0109] Among them, s1 and s2 are weight coefficients with fixed values. The values ​​of s1 and s2 are both greater than zero. s1 is the weight of the object, and s2 is the weight of the object volume. It can be understood that when the numerator is a fixed value, the smaller the mass, volume, and fragility of the logistics shipment, the lower the security inspection efficiency of the corresponding inspected shipment. When the denominator is a fixed value, the longer the security inspection takes, the lower the security inspection efficiency of the corresponding inspected shipment.

[0110] The value obtained by adding up the security inspection time coefficients of each inspected shipment and taking the average value is set as the security inspection time reference coefficient HSC;

[0111] The estimated inspection time YT for the cargo to be inspected in the inspection area is calculated according to the formula. The specific formula is as follows:

[0112]

[0113] Where i' is the serial number of the item to be inspected, and the upper limit of i is equal to the number of items to be inspected;

[0114] Obtain the critical departure time of the security inspection area and compare the estimated security inspection time YT of the goods to be inspected with the critical departure time LT;

[0115] If YT≤LT, the estimated detention situation in the corresponding security inspection area is determined to be no cargo detention;

[0116] If LT<YT≤1.5×LT, the estimated detention situation in the corresponding security inspection area is determined to be a minor cargo detention;

[0117] If 1.5×LT<YT, the estimated detention situation in the corresponding security inspection area is determined to be heavy cargo detention;

[0118] The process analysis module sends the estimated detention situation in the security inspection area to the server, and the server sends the estimated detention situation in the security inspection area to the scheduling terminal.

[0119] In specific implementation, the dispatch terminal is used to dispatch security inspection resources in each security inspection area. The module working process is as follows:

[0120] If the estimated detention situation is that there is no shipment detention, no additional security inspection resources will be dispatched;

[0121] If the estimated holdup is minor, additional security inspection resources will be dispatched to the corresponding security inspection area. For example, additional security inspection lanes will be opened and idle security inspection equipment will be activated.

[0122] If the estimated holdup is severe, additional security resources will be dispatched to the corresponding security inspection area, and staff will be sent to conduct manual security inspections.

[0123] In this application, if a corresponding calculation formula appears, the above calculation formula is dimensionless and its numerical calculation is performed. The weight coefficient, proportional coefficient and other coefficients in the formula are set to a result value obtained by quantifying each parameter. Regarding the size of the weight coefficient and the proportional coefficient, as long as it does not affect the proportional relationship between the parameter and the result value, it is acceptable.

[0124] Example 2:

[0125] See also Figure 5 As shown, based on another concept of the same invention, a pre-security inspection logistics tracking method is now proposed, including the following steps:

[0126] Step S101: The information extraction module obtains the object specification information of the logistics shipment and sends it to the pre-screening module and the process analysis module;

[0127] In step S102, the pre-screening module performs preliminary screening on the logistics shipments in the security inspection state, and sends the pre-screening plan for the logistics shipments obtained through screening to the execution terminal. The execution terminal transfers the corresponding logistics shipments for transportation according to the pre-screening plan;

[0128] Step S103: After the logistics shipment is transferred to the waiting area corresponding to the pre-security inspection solution, the process tracking module monitors the security inspection process of the logistics shipment in real time and sends the security inspection process data obtained in the security inspection area to the process analysis module;

[0129] In step S104, the process analysis module conducts a comprehensive analysis of the logistics cargo detention situation in the security inspection area, obtains an estimated detention situation in the security inspection area, and sends it to the scheduling terminal, which schedules the security inspection resources of each security inspection area.

The pre-security inspection logistics tracking system according to claim 1, characterized in that: The module working process of the dispatch terminal is as follows: If the estimated detention situation is that there is no shipment detention, no additional security inspection resources will be dispatched; If the estimated holdup is minor, additional security inspection resources will be dispatched to the corresponding security inspection area; If the estimated detention situation is a heavy cargo detention, additional security inspection resources will be dispatched to the corresponding security inspection area, and staff will be dispatched to conduct manual security inspections.

5. A pre-security inspection logistics tracking method, characterized in that: Based on the pre-security inspection logistics tracking system according to any one of claims 1 to 4, the method steps specifically include: Step S101: The information extraction module obtains the object specification information of the logistics shipment and sends it to the pre-screening module and the process analysis module; In step S102, the pre-screening module performs preliminary screening on the logistics shipments in the security inspection state, and sends the pre-screening plan for the logistics shipments obtained through screening to the execution terminal. The execution terminal transfers the corresponding logistics shipments for transportation according to the pre-screening plan; Step S103: After the logistics shipment is transferred to the waiting area corresponding to the pre-security inspection solution, the process tracking module monitors the security inspection process of the logistics shipment in real time and sends the security inspection process data obtained in the security inspection area to the process analysis module; In step S104, the process analysis module conducts a comprehensive analysis of the logistics cargo detention situation in the security inspection area, obtains an estimated detention situation in the security inspection area, and sends it to the scheduling terminal, which schedules the security inspection resources of each security inspection area.
