Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product transportation, and in particular to a method for tracing the quality and safety of agricultural products based on the agricultural Internet of Things. Background Art

[0002] The importance of agricultural product quality and safety traceability cannot be ignored. Through detailed records and tracking, we can ensure that every link from the origin to the table is under supervision, effectively reducing food safety risks. Through the full-chain information traceability model, we can effectively solve the problem of information asymmetry and establish a quality information exchange mechanism for each link and a potential punishment mechanism for quality and safety responsibilities.

[0003] During the transportation of agricultural products, the logistics situation will be monitored and managed in real time through GPS positioning, and real-time tracking of agricultural product transportation vehicles will be achieved. This real-time tracking not only ensures the safety of agricultural products during transportation, but also can promptly detect and adjust vehicles that deviate from the normal route, and display the route of the transportation vehicle from the place of production to the place of sale to consumers, thereby achieving transparency and security of the entire supply chain.

[0004] However, agricultural vehicles at the origin of some agricultural products do not have the hardware conditions for GPS, and even if they are equipped with GPS devices, the GPS positioning effect may be affected due to farmers' lack of professional skills. Therefore, a method for tracing the quality and safety of agricultural products based on the agricultural Internet of Things is needed to realize the positioning assistance function of agricultural vehicles at the origin. Summary of the invention

[0005] The purpose of the present invention is to provide a method for tracing the quality and safety of agricultural products based on the agricultural Internet of Things to solve the following technical problems:

[0006] For some agricultural products’ places of origin, agricultural vehicles do not have the hardware conditions for GPS, and even if they are equipped with GPS devices, the GPS positioning effect may be affected due to farmers’ lack of professional skills.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A method for tracing the quality and safety of agricultural products based on the agricultural Internet of Things, comprising the following steps:

[0009] Obtain the geographic coordinates of the agricultural product purchasing station. There are several stations set up on the roads near the agricultural product purchasing station. The geographic coordinates of the stations are also recorded. Whenever a farm vehicle with the destination of the agricultural product purchasing station passes through the station, the station personnel record the current time, the type and quantity of agricultural products transported by the farm vehicle, and the identification information of the farm vehicle;

[0010] The agricultural vehicles that arrive at the purchasing station on the same day are marked as C1, C2, ..., Cn according to the arrival time; the stations passed by any agricultural vehicle Ci are marked as S1, S2, ..., Sm according to the time sequence. i , i∈[1,n], n represents the number of agricultural vehicles, m i It represents the number of stations that any agricultural vehicle Ci passes through, with the order of agricultural vehicles as the C axis and the order of stations as the S axis. The state coordinate (Ci, Sj) represents the state of any vehicle when it passes through any station, j∈[1,m i ],

[0011] Generate the initial coordinates (C1, S1) according to the first station S1 passed by the first agricultural vehicle C1, and mark the identification information of the C1 vehicle in the geographic coordinates of the S1 station on the map, set the generation length m1-1, and generate the path for the S coordinates. Keep the C coordinates unchanged each time, and the S address sequence is automatically increased by 1. Generate new state coordinates (C1, Sj) in sequence, and mark the identification information of the C1 vehicle in the geographic coordinates of the Sj station on the map until j=m1, and the transportation path generation of the C1 agricultural vehicle is completed;

[0012] According to the order of agricultural vehicles, collect the agricultural vehicles Ci and pass through the first station S1 to generate coordinates (Ci, S1), and then correspond to m i -1 transport routes are generated until i=n, ​​and the transport routes of all agricultural vehicles on that day are generated.

[0013] As a further solution of the present invention: the identification information of the agricultural vehicle includes but is not limited to the license plate number of the agricultural vehicle, the mobile phone number and ID card number of the driver.

[0014] As a further solution of the present invention: for any vehicle Ci, the transportation path generated by it is obtained, all the stations passed by the vehicle are connected in the map to generate a transportation track, and the transportation track is extended to the agricultural product purchasing station.

[0015] As a further solution of the present invention: for any vehicle Ci, a mark corresponding to the arrival time, type and quantity of the transported products will be added to each station passed by in the map.

[0016] As a further solution of the present invention: each site corresponds to a sub-database, the database label is the geographical coordinates of the site, and when each agricultural vehicle passes through the site, the current time, the type and quantity of agricultural products transported by the agricultural vehicle, and the identification information of the agricultural vehicle are stored in the sub-database.

[0017] As a further solution of the present invention: after the purchasing work of the purchasing station is completed every day, paths are generated for all the agricultural vehicles that arrive. At this time, all the sub-databases of the day are merged into a total database, and the data generated by the path is based on the total database.

[0018] As a further solution of the present invention: in the path generation of any vehicle Ci, when a new state coordinate (Ci, Sj) is generated, the sub-database corresponding to Sj is obtained, and the corresponding data is retrieved in the Sj sub-database using the identification information of Ci as an index.

[0019] Beneficial effects of the present invention:

[0020] The present invention realizes the positioning auxiliary function of the vehicle by setting up several stations in the road near the agricultural product purchasing station and recording the geographical coordinates of the stations. This method reduces the technical requirements for the vehicle's own equipment; the method of recording time and vehicle information by station personnel is simple and easy, and does not require farmers to have complex technical knowledge, so that even farmers with low technical levels can easily participate in it; because the stations are fixed and their geographical coordinates have been recorded in the system, the information records when the agricultural vehicles pass through these stations can assist in correcting or verifying GPS data, thereby improving the overall positioning accuracy; even if the agricultural vehicle does not have GPS equipment or the GPS signal is poor, the whole process monitoring of agricultural products from the place of origin to the purchasing station can also be achieved through the station recording method, ensuring the continuity and effectiveness of supervision; the present invention has low technical requirements for vehicles, making the system more robust, able to adapt to agricultural product logistics tracking in different regions and under different technical conditions, and improving the overall applicability of the system; it provides a simple way for traditional agriculture to access modern Internet of Things technology, which helps traditional agriculture to gradually transform and upgrade, and enjoy the convenience and security brought by modern information technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 As shown, the present invention is a method for tracing the quality and safety of agricultural products based on the agricultural Internet of Things, comprising the following steps:

[0025] Obtain the geographic coordinates of the agricultural product purchasing station. There are several stations set up on the roads near the agricultural product purchasing station. The geographic coordinates of the stations are also recorded. Whenever a farm vehicle with the destination of the agricultural product purchasing station passes through the station, the station personnel record the current time, the type and quantity of agricultural products transported by the farm vehicle, and the identification information of the farm vehicle;

[0026] The agricultural vehicles that arrive at the purchasing station on the same day are marked as C1, C2, ..., Cn according to the arrival time; the stations passed by any agricultural vehicle Ci are marked as S1, S2, ..., Sm according to the time sequence. i , i∈[1,n], n represents the number of agricultural vehicles, m i It represents the number of stations that any agricultural vehicle Ci passes through, with the order of agricultural vehicles as the C axis and the order of stations as the S axis. The state coordinate (Ci, Sj) represents the state of any vehicle when it passes through any station, j∈[1,m i ],

[0027] Generate the initial coordinates (C1, S1) according to the first station S1 passed by the first agricultural vehicle C1, and mark the identification information of the C1 vehicle in the geographic coordinates of the S1 station on the map, set the generation length m1-1, and generate the path for the S coordinates. Keep the C coordinates unchanged each time, and the S address sequence is automatically increased by 1. Generate new state coordinates (C1, Sj) in sequence, and mark the identification information of the C1 vehicle in the geographic coordinates of the Sj station on the map until j=m1, and the transportation path generation of the C1 agricultural vehicle is completed;

[0028] According to the order of agricultural vehicles, collect the agricultural vehicles Ci and pass through the first station S1 to generate coordinates (Ci, S1), and then correspond to m i -1 transport routes are generated until i=n, ​​and the transport routes of all agricultural vehicles on that day are generated.

[0029] This method does not require that each agricultural vehicle be equipped with a GPS device. Instead, it realizes the positioning assistance function of the vehicle by setting up several stations on the roads near the agricultural product purchasing stations and recording the geographical coordinates of the stations. This method reduces the technical requirements for the vehicle's own equipment; by obtaining the transportation data and station information of the agricultural vehicle, the system can automatically generate the transportation path of each agricultural vehicle and display it intuitively on the map. This greatly improves the monitoring ability of each link in the transportation process of agricultural products and improves the efficiency and accuracy of traceability.

[0030] When quality problems arise, the system can quickly locate the source of the problem product and its transportation trajectory, helping to quickly recall or take other necessary response measures to reduce losses and risks.

[0031] In another preferred embodiment of the present invention, the identification information of the agricultural vehicle includes but is not limited to the license plate number of the agricultural vehicle, the mobile phone number and ID card number of the driver.

[0032] In another preferred embodiment of the present invention, for any vehicle Ci, the transportation path generated by it is obtained, all the stations passed by the vehicle are connected in the map to generate a transportation track, and the transportation track is extended to the agricultural product purchasing station.

[0033] In another preferred embodiment of the present invention, for any vehicle Ci, a mark corresponding to the arrival time, type and quantity of the transported products will be added to each station passed by in the map.

[0034] Through detailed tracking of agricultural vehicle transportation routes and real-time updating of data, any abnormal situation in the logistics process can be discovered in time, so that corresponding measures can be taken to ensure the quality and safety of agricultural products.

[0035] In another preferred embodiment of the present invention, each site corresponds to a sub-database, the label of the database is the geographical coordinates of the site, and when each agricultural vehicle passes through the site, the current time, the type and quantity of agricultural products transported by the agricultural vehicle, and the identification information of the agricultural vehicle are stored in the sub-database.

[0036] In another preferred embodiment of the present invention, after the purchasing work of the purchasing station is completed every day, paths are generated for all the agricultural vehicles that arrive. At this time, all the sub-databases of the day are merged into a total database, and the data generated by the path is based on the total database.

[0037] This method allows key information such as the identification information of agricultural vehicles, arrival time, type and quantity of transported products to be recorded in the sub-database corresponding to each station and finally merged into a master database. This centralized management and transparent display of information helps consumers and other stakeholders understand the origin and flow of agricultural products.

[0038] In another preferred embodiment of the present invention, in the path generation of any vehicle Ci, when a new state coordinate (Ci, Sj) is generated, the sub-database corresponding to Sj is obtained, and the corresponding data is retrieved in the Sj sub-database using the identification information of Ci as an index.

[0039] The collected data can be used to analyze the circulation patterns, transportation efficiency and bottlenecks in the supply chain of agricultural products, thereby guiding the optimization decisions of agricultural production and logistics and improving the performance of the entire supply chain.

[0040] Systematic data collection and management are conducive to ensuring that the circulation of agricultural products complies with relevant laws and regulations and reduces the risk of violations.

[0041] Since the information is stored in the database and can be presented visually through maps and other forms, producers, consumers, regulators and other relevant parties can access and share important information more easily.

[0042] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
