Description

Technical Field

[0001] This invention relates to the field of vehicle identification technology, and in particular to a vehicle identification system and method for a waste unloading platform. Background Technology

[0002] With the continuous improvement of living standards in today's society, the amount of various industrial and domestic waste generated daily is also rapidly increasing. To meet people's demands for environmental protection and sanitation, it is necessary to quickly and efficiently process the large amounts of waste generated in cities. Currently, large and medium-sized cities typically require a large number of garbage trucks to transport various types of waste from all over the city to the unloading platform of waste treatment stations for further processing. However, due to the sanitation issues of garbage trucks, most of them need to unload at the unloading platform during peak hours, facing the problems of short working hours and large workloads. This also leads to multiple garbage trucks at the unloading platform being disorganized and often causing congestion, reducing unloading efficiency. Therefore, there is an urgent need for a system and method that can enable a large number of garbage trucks to transport urban waste to the unloading platform for orderly unloading within a limited time.

[0003] Furthermore, waste sorting can increase the resource and economic value of waste, reduce the amount of waste to be processed and the use of processing equipment, and lower processing costs. However, during the unloading process, due to a lack of management and guidance, garbage trucks inevitably unload waste into unloading ports that do not match the waste type. Over time, this can lead to damage to waste processing equipment and reduce the economic value of the waste.

[0004] Invention patent CN112429445B proposes an intelligent control method and system for garbage transfer stations. It allocates appropriate garbage compression bins to garbage trucks by calculating the garbage load and the garbage compression bin load. However, this invention fails to solve the problem of low garbage truck unloading efficiency. Furthermore, this invention uses cameras to identify the license plate numbers of garbage trucks, but garbage trucks are prone to image recognition failure due to dirt, thus the invention also suffers from inaccurate vehicle identification. Invention patent CN108639632B proposes a garbage unloading yard, which includes a garbage pit, an unloading platform, an unloading gate, and a drive mechanism. The drive mechanism controls the opening and closing of the unloading gate, thereby solving the safety problem of garbage truck unloading. However, this invention also fails to solve the problem of low unloading efficiency. Summary of the Invention

[0005] Purpose of the invention: To address the above problems, this invention proposes a vehicle identification system and method for waste unloading platforms.

[0006] Technical solution:

[0007] Firstly, this invention proposes a vehicle identification system for a waste unloading platform.

[0008] Includes: multiple primary terminals, multiple garbage trucks, a garbage unloading platform, multiple secondary terminals, a primary identification device, a secondary identification device, a central management server, and a route guidance system;

[0009] Among them, the first terminal, the second terminal, the first identification device, the second identification device, and the route guidance system are all connected to the central management server.

[0010] Preferably, the first terminal is bound to each garbage truck and is used to upload garbage information from the garbage truck to the central management server.

[0011] Each of the second terminals is located at each waste unloading port of the unloading platform;

[0012] The first identification device is installed at the entrance of the unloading platform and is used to identify garbage information inside the garbage truck;

[0013] The second identification device is installed at the entrance of the unloading platform and is used to identify the vehicle information of the garbage truck;

[0014] The route guidance system is used to guide garbage trucks to the garbage unloading port.

[0015] Preferably, the first terminal is a portable terminal for the driver of the garbage truck.

[0016] Preferably, the binding relationship between the first terminal and the garbage truck is pre-set in the central management server;

[0017] The central management server parses the first terminal number based on the information received from the first terminal, and obtains the vehicle information of the garbage truck according to the above binding relationship.

[0018] Preferably, the garbage inside the garbage truck is photographed from above by the first identification device; the image is then sent to the central management server.

[0019] The central management server identifies spam messages based on image recognition algorithms.

[0020] Preferably, the second identification device is an RFID identification device and / or an NFC identification device; the vehicle sensor identification number of the garbage truck is identified by the second identification device.

[0021] Secondly, the present invention also provides a vehicle identification method for a waste unloading platform, comprising:

[0022] 1. Sorting and loading waste into garbage trucks, identifying waste information, including:

[0023] Each garbage truck carries only one type of waste to be processed;

[0024] The staff of each garbage truck identify the type of garbage being transported, configure type label information in the first terminal, and upload the type label information to the central management server;

[0025] The central management server stores the type label in the first mapping table;

[0026] The first mapping table also stores the vehicle model and the standard unloading time corresponding to the vehicle model;

[0027] 2. Identify the vehicle information of incoming garbage trucks at the entrance of the unloading platform of the garbage treatment station, including:

[0028] The first identification device identifies the garbage inside the garbage truck and obtains information about the current type of garbage.

[0029] The vehicle's sensor identification number is identified by a second identification device;

[0030] The central management server queries the first mapping table based on the vehicle's sensor identification number to obtain the vehicle's type label information; the central management server automatically compares the current waste type information with the type label information to see if they match.

[0031] If there is a discrepancy, an inspection team will conduct a manual re-inspection.

[0032] If the results of automatic comparison and manual review are inconsistent, the type label information in the first mapping table will be updated, and the process will proceed to the next step.

[0033] Otherwise, proceed directly to the next step;

[0034] III. Configure matching unloading ports for garbage trucks according to type label information, including:

[0035] Several waste discharge ports that have the same type of waste and type label information are used as matching discharge ports for waste transport vehicles;

[0036] IV. Among the several matching waste discharge ports, the target discharge port is analyzed and determined, including:

[0037] Step 1: Calculate the estimated waiting time T for each matched discharge port;

[0038] 1) If the matching unloading port is empty, determine whether there is already a garbage truck on its way to the empty matching unloading port. If not, let T = 0;

[0039] If there are n garbage trucks on their way to the available matching unloading point, and n≥1, then let...

[0040]

[0041] Where t i Let be the standard unloading time of the i-th vehicle on the road, 1≤i≤n, and Δt be the travel time of the garbage truck on the road.

[0042] 2) If there is one garbage truck unloading at the matching unloading port and no garbage trucks are queuing, then determine whether there is already a garbage truck on its way to the matching unloading port.

[0043] If not, let T = t B -t B ';

[0044] If there are m garbage trucks on their way to the matching unloading point, where m ≥ 1, then let...

[0045]

[0046] Where t B The standard unloading time for a vehicle currently unloading material, t B 't' represents the unloading time of vehicles currently unloading. j Let m be the standard unloading time of the j-th vehicle on the road, where 1 ≤ j ≤ m;

[0047] 3) If there is one garbage truck unloading at the matching unloading port, and there are q garbage trucks in the queue, and no garbage trucks are on their way to the matching unloading port, then q≥1.

[0048]

[0049] Where 1≤w≤q, t w To match the standard unloading time of the wth vehicle currently queuing at the unloading port;

[0050] If there are p garbage trucks on their way to the matching unloading point, where p ≥ 1, then

[0051]

[0052] Where 1≤w≤q, 1≤k≤p, t k The standard unloading time for the kth vehicle on the road;

[0053] Step 2: Calculate the estimated total time T' for each matched discharge port, including:

[0054] T' = T + t e +t r ,

[0055] Where te The standard unloading time for vehicles awaiting allocation, t r Travel time of vehicles to be assigned;

[0056] Step 3: Compare the estimated total time for each matched unloading port for the vehicles to be assigned; select the matched unloading port with the smallest estimated total time as the optimal unloading port;

[0057] Step 4: Select the optimal discharge port as the target discharge port;

[0058] V. Guide garbage trucks to the target unloading point using the route guidance system, including:

[0059] The central management server extracts the license plate numbers of the garbage trucks to be assigned from the first mapping table and sends them to the route guidance system;

[0060] The central management server sends the target unloading port location to the route guidance system;

[0061] The route guidance system generates a planned route and displays guidance information on guidance display panels at key locations along the route;

[0062] The guidance information includes the license plate number of the garbage truck to be assigned and the direction of movement.

[0063] The garbage trucks arrived at the target unloading point following the guidance information;

[0064] 6. When the garbage truck arrives at the target unloading port, the second terminal identifies the vehicle's sensor identification number and unloads the garbage.

[0065] The central management server extracts the vehicle sensor identification number and type label information, and generates several second mapping tables, with one second mapping table generated for each type label information.

[0066] The central management server sends the second mapping table to several second terminals whose garbage types and type label information are consistent.

[0067] The second terminal identifies the vehicle's sensor identification number; it then queries the vehicle identification number in the second mapping table within the second terminal.

[0068] If the query result is empty, staff will be arranged to guide the garbage truck to the correct garbage unloading port;

[0069] If the query result is not empty, the unloading port gate will be opened to start unloading;

[0070] Leave after unloading is complete.

[0071] Preferably, the standard unloading time in step one is data pre-stored in the server;

[0072] By statistically analyzing a large amount of data, the unloading time of different models of garbage trucks was determined. The average unloading time of the same model of garbage truck was then used as the standard unloading time for that model of garbage truck.

[0073] Preferably, step one further includes pre-setting the binding relationship between the first terminal and the garbage truck in the central management server;

[0074] The central management server receives information uploaded by the first terminal, parses the source information frame in the information message, obtains the number of the first terminal that uploaded the information, and obtains the license plate number and vehicle sensor identification number of the corresponding garbage truck based on the above binding relationship.

[0075] The vehicle sensor identification number, license plate number, first terminal number, and type label information are then entered into the first mapping table.

[0076] Preferably, in step two, the garbage inside the garbage truck is identified to obtain information about the current type of garbage;

[0077] Specifically, this includes using a first identification device to photograph the garbage inside the garbage truck from above and sending the image to a central management server;

[0078] The central management server identifies the current type of garbage using an image recognition algorithm.

[0079] Thirdly, the present invention proposes a computer storage medium storing one or more programs, which can be executed by one or more processors to enable the one or more processors to execute the above-described vehicle identification method for waste unloading platforms.

[0080] The present invention has the following advantages over the prior art:

[0081] 1. This invention, by installing a first identification device and a second identification device at the entrance of the unloading platform, and through the coordinated use of the first and second identification devices, can effectively improve the accuracy of waste truck unloading and significantly reduce driver errors. Correct unloading facilitates subsequent waste sorting and processing and greatly benefits the extension of the service life of waste treatment equipment.

[0082] 2. This invention, through analysis and judgment by a central management server, comprehensively considers unloading vehicles at the unloading port, queuing vehicles, and vehicles on the road to calculate the waiting time and total time for each unloading port, thereby selecting the optimal unloading port for the garbage trucks to be assigned. This can significantly reduce the waiting time of garbage trucks, improve unloading efficiency, and ensure that the unloading process can proceed in an orderly and efficient manner.

[0083] 3. Existing vehicle identification technologies primarily rely on license plate recognition. However, due to the unique working environment of garbage trucks, license plates are easily soiled, leading to potential errors in license plate recognition. This invention employs a sensor device to identify vehicle identification numbers, thereby improving the accuracy of vehicle identification. However, when providing route guidance, to facilitate quick access to guidance information for drivers, the license plate number is still extracted based on a mapping relationship, and route guidance is still provided through the license plate number. This ensures a positive user experience for route guidance, enabling drivers to accurately follow the guided route to the correct unloading port.

[0084] 4. This invention, by setting up a second terminal at the unloading port for re-identification and verification, can prevent drivers from going to the wrong unloading port due to incorrect routes within the waste treatment station. When the second terminal performs verification, it does not require the vehicle to necessarily be at the optimal unloading port; it only needs to be at a port that matches the type of waste it is transporting. This is because route correction usually takes a long time and can affect the route guidance of subsequent vehicles, easily causing disorderly unloading and traffic congestion. Therefore, even if the vehicle does not follow the correct optimal unloading port route, it is allowed to unload as long as it reaches an unloading port matching the waste type; correction is only required if the vehicle reaches an incompatible unloading port. This setup balances unloading efficiency and unloading accuracy. Attached Figure Description

[0089] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0090] Example 1:

[0091] like Figure 1 As shown, this invention proposes a vehicle identification system for a waste unloading platform.

[0092] Includes: multiple primary terminals, multiple garbage trucks, a garbage unloading platform, multiple secondary terminals, a primary identification device, a secondary identification device, a central management server, and a route guidance system;

[0093] Among them, the first terminal, the second terminal, the first identification device, the second identification device, and the route guidance system are all connected to the central management server.

[0094] Preferably, the first terminal is bound to each garbage truck and is used to upload garbage information from the garbage truck to the central management server.

[0095] Each of the second terminals is located at each waste unloading port of the unloading platform;

[0096] The first identification device is installed at the entrance of the unloading platform and is used to identify garbage information inside the garbage truck;

[0097] The second identification device is installed at the entrance of the unloading platform and is used to identify the vehicle information of the garbage truck;

[0098] The route guidance system is used to guide garbage trucks to the garbage unloading port.

[0099] Preferably, the central management server stores a first mapping table, which contains the serial number of the first terminal and the vehicle identifier, and stores the serial number of the first terminal and the vehicle information in a one-to-one correspondence; the central management server receives type tag information uploaded by the first terminal and stores the type tag information in the first mapping table. The vehicle information includes vehicle identification information and vehicle unloading information; the vehicle identification information includes the license plate number, vehicle sensor identification number, and vehicle model; the vehicle unloading information includes the standard unloading time of the vehicle.

[0100] Among them, staff can be the drivers of each garbage truck. Before, after, or during the loading of garbage into the garbage truck, the drivers can determine the type of garbage being transported, set type label information on the first terminal, and upload it to the central management server.

[0101] For example, the first mapping table is shown in Table 1 below:

[0102] Vehicle identification number N1 N2 N3 License plate number A1XXX5 B1XXX5 C1XXX5 First terminal number Z1 Z2 Z3 Type label information L1 L2 L3 Vehicle model X1 X2 X3 Standard discharge time t1 t2 t3

[0103] Preferably, the first terminal is a portable terminal for the driver of the garbage truck.

[0104] Preferably, the binding relationship between the first terminal and the garbage truck is pre-set in the central management server;

[0105] The central management server parses the first terminal number based on the information received from the first terminal, and obtains the vehicle information of the garbage truck according to the above binding relationship.

[0106] Preferably, the garbage inside the garbage truck is photographed from above by the first identification device; the image is then sent to the central management server.

[0107] The central management server identifies spam messages based on image recognition algorithms.

[0108] Preferably, the second identification device is an RFID identification device and / or an NFC identification device; the vehicle sensor identification number of the garbage truck is identified by the second identification device.

[0109] Example 2:

[0110] like Figure 2 and Figure 3 The present invention also provides a vehicle identification method for a waste unloading platform, comprising:

[0111] 1. Sorting and loading waste into garbage trucks, identifying waste information, including:

[0112] Each garbage truck carries only one type of waste to be processed;

[0113] The staff of each garbage truck identify the type of garbage being transported, configure type label information in the first terminal, and upload the type label information to the central management server;

[0114] The central management server stores the type label in the first mapping table;

[0115] The first mapping table also stores the vehicle model and the standard unloading time corresponding to the vehicle model;

[0116] 2. Identify the vehicle information of incoming garbage trucks at the entrance of the unloading platform of the garbage treatment station, including:

[0117] The first identification device identifies the garbage inside the garbage truck and obtains information about the current type of garbage.

[0118] The vehicle's sensor identification number is identified by a second identification device;

[0119] The central management server queries the first mapping table based on the vehicle's sensor identification number to obtain the vehicle's type label information; the central management server automatically compares the current waste type information with the type label information to see if they match.

[0120] If there is a discrepancy, an inspection team will conduct a manual re-inspection.

[0121] If the results of automatic comparison and manual review are inconsistent, the type label information in the first mapping table will be updated, and the process will proceed to the next step.

[0122] Otherwise, proceed directly to the next step;

[0123] This invention identifies the type of waste transported by the vehicle at the entrance of the unloading platform and determines whether it matches the waste type label information uploaded by the driver. This is because drivers may misidentify the waste type or mistakenly upload the wrong type. This feature effectively improves the accuracy of waste sorting and processing. After determining the type of waste being transported, accurate type label information can be obtained, facilitating subsequent steps to configure the appropriate unloading port for the vehicle based on the type label information.

[0124] III. Configure matching unloading ports for garbage trucks according to type label information, including:

[0125] Several waste discharge ports that have the same type of waste and type label information are used as matching discharge ports for waste transport vehicles;

[0126] IV. Among the several matching waste discharge ports, the target discharge port is analyzed and determined, including:

[0127] Step 1: Calculate the estimated waiting time T for each matched discharge port;

[0128] 1) If the matching unloading port is empty, determine whether there is already a garbage truck on its way to the empty matching unloading port. If not, let T = 0;

[0129] If there are n garbage trucks on their way to the available matching unloading point, and n≥1, then let...

[0130]

[0131] Where t i Let be the standard unloading time of the i-th vehicle on the road, 1≤i≤n, and Δt be the travel time of the garbage truck on the road.

[0132] In general, when there are multiple vehicles on the road, the subsequent vehicles have already reached the unloading port and are queuing up when the first vehicle starts unloading but has not yet finished unloading. Therefore, only the travel time of the first vehicle needs to be considered. Thus, △t is preferably the travel time of the garbage truck on the road that is closest to the matching unloading port, which can be estimated by the current position of the vehicle and the position of the matching unloading port.

[0133] 2) If there is one garbage truck unloading at the matching unloading port and no garbage trucks are queuing, then determine whether there is already a garbage truck on its way to the matching unloading port.

[0134] If not, let T = t B -t B ';

[0135] If there are m garbage trucks on their way to the matching unloading point, where m ≥ 1, then let...

[0136]

[0137] Where t B The standard unloading time for a vehicle currently unloading material, t B 't' represents the unloading time of vehicles currently unloading. j Let m be the standard unloading time of the j-th vehicle on the road, where 1 ≤ j ≤ m;

[0138] 3) If there is one garbage truck unloading at the matching unloading port and q garbage trucks are queuing, then determine whether there is already a garbage truck on its way to the matching unloading port; if there is no garbage truck on its way to the matching unloading port, q≥1, then...

[0139]

[0140] Where 1≤w≤q, t w To match the standard unloading time of the wth vehicle currently queuing at the unloading port;

[0141] If there are p garbage trucks on their way to the matching unloading point, p ≥ 1, then... Figure 4 As shown, then

[0142]

[0143] Where 1≤w≤q, 1≤k≤p, t k The standard unloading time for the kth vehicle on the road;

[0144] In general, if there are q vehicles already in the queue, the vehicles on the road will usually arrive before all the vehicles in the queue have finished unloading. Therefore, in this case, there is no need to consider the travel time.

[0145] Step 2: Calculate the estimated total time T' for each matched discharge port, including:

[0146] T' = T + t e +t r ,

[0147] Where t e The standard unloading time for vehicles awaiting allocation, t r Travel time of vehicles to be assigned;

[0148] Step 3: Compare the estimated total time for each matched unloading port for the vehicles to be assigned; select the matched unloading port with the smallest estimated total time as the optimal unloading port;

[0149] Step 4: Select the optimal discharge port as the target discharge port;

[0150] In this process, it is essential to guide garbage trucks to the appropriate unloading port that matches the type of garbage, which facilitates subsequent waste processing. Furthermore, in large-scale waste treatment plants, multiple unloading ports are typically provided for each type of garbage, meaning that multiple unloading ports match the garbage type of the garbage truck. This invention can identify the optimal unloading port through analysis and judgment. Through the analysis and calculation of this invention, the waiting time of vehicles can be minimized, thereby improving the efficiency of vehicle unloading and effectively avoiding disorderly unloading and vehicle congestion. This solves the problem of disorder caused by a large number of garbage trucks unloading at the same time in the prior art.

[0151] V. Guide garbage trucks to the target unloading point using the route guidance system, including:

[0152] The central management server extracts the license plate numbers of the garbage trucks to be assigned from the first mapping table and sends them to the route guidance system;

[0153] The central management server sends the target unloading port location to the route guidance system;

[0154] The route guidance system generates a planned route and displays guidance information on guidance display panels at key locations along the route;

[0155] The guidance information includes the license plate number of the garbage truck to be assigned and the direction of movement.

[0156] The garbage trucks arrived at the target unloading point following the guidance information;

[0157] In existing technologies, vehicle identification primarily relies on license plate recognition. However, due to the unique working environment of garbage trucks, license plates are easily soiled, leading to potential errors in license plate recognition. Therefore, this invention employs a sensor device to identify vehicle sensor identifiers, thereby improving the accuracy of vehicle identification. However, if vehicle sensor identifiers are still used for vehicle guidance, drivers may struggle to quickly find the correct route, as they typically rely on and memorize license plate numbers, not vehicle sensor identifiers. Therefore, to facilitate driver access to guidance information, license plate numbers are extracted from a first mapping table, binding them to guidance information and enabling drivers to quickly understand the correct route.

[0158] 6. When the garbage truck arrives at the target unloading port, the second terminal identifies the vehicle's sensor identification number and unloads the garbage.

[0159] The central management server extracts the vehicle sensor identification number and type label information, and generates several second mapping tables, with one second mapping table generated for each type label information.

[0160] The central management server sends the second mapping table to several second terminals whose garbage types and type label information are consistent.

[0161] The second terminal identifies the vehicle's sensor identification number; it then queries the vehicle identification number in the second mapping table within the second terminal.

[0162] If the query result is empty, staff will be arranged to guide the garbage truck to the correct garbage unloading port;

[0163] If the query result is not empty, the unloading port gate will be opened to start unloading;

[0164] Leave after unloading is complete.

[0165] Existing technologies rely on license plate recognition, but such systems are expensive. Installing a license plate recognition system at every waste unloading point would significantly increase costs, and the poor environment of waste treatment stations could easily lead to recognition errors and equipment damage. This invention stores license plate numbers and vehicle sensor identification numbers in a mapping table, and uses a sensor device to identify vehicle identification information, which is fast, accurate, and low-cost.

[0166] By conducting a second terminal inspection at the unloading port, drivers can be prevented from deviating from the correct route within the waste treatment station and ending up at the wrong unloading port. Furthermore, the second terminal inspection does not require the vehicle to necessarily reach the optimal unloading port; it only requires that the vehicle enters the unloading port consistent with the type of waste it is transporting. This is because route correction typically takes a considerable amount of time and can affect the route guidance of subsequent vehicles, easily leading to disorderly unloading and traffic congestion. Therefore, even if a vehicle does not follow the correct optimal unloading port route, it is allowed to unload as long as it reaches the matching unloading port. Correction is only required if the vehicle reaches an incompatible unloading port. This setup balances unloading efficiency and accuracy.

[0167] Preferably, the standard unloading time in step one is data pre-stored in the server;

[0168] By statistically analyzing a large amount of data, the unloading time of different models of garbage trucks was determined. The average unloading time of the same model of garbage truck was then used as the standard unloading time for that model of garbage truck.

[0169] Preferably, the method further includes obtaining the garbage loading capacity of the garbage truck, calculating the ratio of the garbage loading capacity to the standard loading capacity of the garbage truck, and correcting the standard unloading time based on the ratio.

[0170] Preferably, step one further includes pre-setting the binding relationship between the first terminal and the garbage truck in the central management server;

[0171] The central management server receives information uploaded by the first terminal, parses the source information frame in the information message, obtains the number of the first terminal that uploaded the information, and obtains the license plate number and vehicle sensor identification number of the corresponding garbage truck based on the above binding relationship.

[0172] The vehicle sensor identification number, license plate number, first terminal number, and type label information are then entered into the first mapping table.

[0173] Preferably, in step two, the garbage inside the garbage truck is identified to obtain information about the current type of garbage;

[0174] Specifically, this includes using a first identification device to photograph the garbage inside the garbage truck from above and sending the image to a central management server;

[0175] The central management server identifies the current type of garbage using an image recognition algorithm.

[0176] Example 3:

[0177] The present invention also provides a computer storage medium storing one or more programs, which can be executed by one or more processors to cause the one or more processors to perform the above-described vehicle identification method for waste unloading platforms.
