However, Bluetooth technology has a low transmission rate, takes a long time to transmit large amounts of data, has poor connection stability, and is easily interfered by the surrounding environment, resulting in data transmission interruptions or errors. When faced with multiple devices connected concurrently, the performance of Wi-Fi technology will drop significantly, and it cannot meet the needs of stable simultaneous connections for many devices in logistics vehicles. The positioning accuracy of Bluetooth and Wi-Fi is far from meeting the requirements of precise logistics distribution. For example, in complex urban environments, it is difficult to accurately determine the location of the vehicle, affecting distribution efficiency and accuracy. In addition, during transportation, logistics vehicles need to monitor massive amounts of data such as cargo status and vehicle operating conditions in real time.

[0021] Please refer to Figure 1 , Figure 1 This is a flow chart of a logistics vehicle on-board application method in some embodiments of the present application. The logistics vehicle on-board application method is used in a terminal device, such as a computer, a mobile phone terminal, etc. The logistics vehicle on-board application method includes the following steps: S11.

[0022] It should be noted that during the transportation process, logistics vehicles should monitor the vehicle condition and the status of the goods in the carriage in real time. The present invention utilizes the low latency, high transmission rate, high concurrency and high-precision positioning advantages of Star Flash technology to improve logistics efficiency and safety. First, the vehicle operation data and carriage operation data of the logistics vehicle are obtained through the Star Flash terminal device installed on the logistics vehicle and including a variety of sensing sensors. The data are processed separately to obtain the vehicle condition evaluation index and the carriage compliance evaluation index, which respectively represent the operating conditions of the vehicle and the carriage. Then, further processing is performed to obtain the operation compliance evaluation index of the logistics vehicle. Finally, the operating status of the logistics vehicle is accurately determined through threshold comparison.

[0023] According to an embodiment of the present invention, the processing according to the vehicle operation data to obtain the vehicle operating condition evaluation index, and the processing according to the compartment operation data to obtain the compartment compliance evaluation index include: The vehicle operation data includes tire pressure deviation rate, water temperature deviation rate, vehicle speed deviation rate and fuel consumption fluctuation rate; A weighted summation process is performed according to the tire pressure deviation rate, the water temperature deviation rate, the vehicle speed deviation rate and the fuel consumption fluctuation rate to obtain a vehicle operating condition evaluation index; The carriage operation data includes real-time temperature difference, real-time humidity difference and gas content difference; A weighted summation process is performed based on the real-time temperature difference, the real-time humidity difference and the gas content difference to obtain a vehicle compartment compliance evaluation index.

[0024] It should be noted that the corresponding parameter data is obtained through the preset sensors, the tire pressure deviation rate refers to the ratio of the absolute value of the difference between the real-time tire pressure and the preset benchmark tire pressure to the preset benchmark tire pressure, the water temperature deviation rate refers to the ratio of the absolute value of the difference between the real-time water temperature and the preset benchmark water temperature to the preset benchmark water temperature, the vehicle speed deviation rate refers to the absolute value of the difference between the real-time vehicle speed and the preset speed limit of the corresponding road section to the preset speed limit, the fuel consumption fluctuation rate refers to the absolute value of the difference between the average fuel consumption in a preset time period and the preset fuel consumption benchmark value and the preset fuel consumption benchmark value.

The gas sensor is used to detect the gas composition in the compartment and promptly discover the leakage of harmful gases or signs of deterioration that may be produced by the goods. For example, for food or pharmaceutical goods, during transportation, the goods themselves may volatilize harmful gases due to packaging damage and temperature changes. For example, some foods will produce hydrogen sulfide and ammonia gases when they deteriorate. The gas content difference refers to the absolute value of the difference between the obtained real-time gas content and the preset gas baseline. The weighted summation processing is performed based on the obtained real-time temperature difference, real-time humidity difference and gas content difference to obtain the compartment compliance evaluation index. The corresponding weight value is obtained by querying the preset logistics and transportation monitoring platform.

[0025] Please refer to Figure 2 , Figure 2 The present invention is a flow chart of a method for obtaining an operation compliance evaluation index of a logistics vehicle in a logistics vehicle on-board application in some embodiments of the present application. According to an embodiment of the present invention, the operation compliance evaluation index of the logistics vehicle is obtained by processing the vehicle operating condition evaluation index and the carriage compliance evaluation index, including: S21, comparing the vehicle operating condition evaluation index with a preset vehicle operating condition reference index to obtain an operating condition stability deviation rate; S22, comparing the carriage compliance evaluation index with a preset carriage operation demand index to obtain a carriage compliance deviation rate; S23. Processing is performed according to the working condition stability deviation rate and the carriage compliance deviation rate to obtain an operation compliance evaluation index of the logistics vehicle.

[0026] It should be noted that in order to evaluate the overall operation of the logistics vehicle according to the vehicle working condition and the compliance of the carriage, the obtained vehicle working condition evaluation index and the carriage compliance evaluation index are first compared with the preset vehicle working condition benchmark index and the preset carriage operation demand index respectively to obtain the working condition stability deviation rate and the carriage compliance deviation rate, wherein the working condition stability deviation rate refers to the ratio of the difference between the vehicle working condition evaluation index and the preset vehicle working condition benchmark index to the preset vehicle working condition benchmark index. For example, the vehicle working condition evaluation index is 7, and the preset vehicle working condition benchmark index is 10, (10-7) / 10=0.3 is the working condition stability deviation rate, and the carriage compliance deviation rate refers to the ratio of the difference between the carriage compliance evaluation index and the preset carriage operation demand index to the preset carriage operation demand index. Then, the obtained working condition stability deviation rate and carriage compliance deviation rate are processed to obtain the operation compliance evaluation index of the logistics vehicle; The calculation formula of the operation compliance evaluation index is: ; in, To run the compliance assessment index, , They are the working condition stability deviation rate and the carriage compliance deviation rate, , It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset logistics and transportation monitoring platform).

[0027] Please refer to Figure 3 , Figure 3 The flowchart of a method for obtaining the operation status of a logistics vehicle in a logistics vehicle on-board application in some embodiments of the present application is as follows. According to an embodiment of the present invention, the operation compliance evaluation index is compared with a preset operation evaluation threshold to obtain the operation status of the logistics vehicle, including: S31, comparing the operation compliance evaluation index with a preset operation compliance benchmark index to obtain an operation compliance relative value; S32, comparing the relative value of the operation compliance with a preset operation evaluation threshold to obtain the operation status of the logistics vehicle; S33. If the relative value of the operation compliance is less than or equal to the preset operation evaluation threshold, the operation state of the logistics vehicle is determined to be an abnormal state; S34. If the relative value of the operation compliance is greater than a preset operation evaluation threshold, the operation status of the logistics vehicle is determined to be normal.

[0028] It should be noted that in order to determine the operating status of the logistics vehicle, the obtained operating compliance evaluation index is compared with the preset operating compliance benchmark index to obtain the relative value of the operating compliance. For example, the operating compliance evaluation index is 7, and the preset operating compliance benchmark index is 10, then 7 / 10=0.7 is the relative value of the operating compliance, and then the threshold is compared with the preset operating evaluation threshold to obtain the operating status of the logistics vehicle. In this embodiment, the preset operating evaluation threshold is set to (0, 0.85], (0.85, 1], corresponding to the abnormal state and the normal state, respectively. For example, if the obtained relative value of the operating compliance is 0.7, which is less than the preset operating evaluation threshold, the operating status of the logistics vehicle is determined to be an abnormal state. If the obtained relative value of the operating compliance is 0.9, which is greater than the preset operating evaluation threshold, the operating status of the logistics vehicle is determined to be a normal state.

[0029] According to an embodiment of the present invention, it also includes: Obtain real-time trajectory data and real-time speed of logistics vehicles; Obtain the dispatch instruction information of the logistics vehicle, and extract the destination location data and time efficiency demand data according to the dispatch instruction information; Processing the real-time trajectory data and the destination location data in combination with the real-time vehicle speed to obtain predicted timeliness data; If the predicted timeliness data is less than or equal to the timeliness demand data, no warning is output; If the predicted timeliness data is greater than the timeliness requirement data, an insufficient timeliness warning is output.

[0030] It should be noted that when a logistics vehicle receives a dispatch instruction to temporarily change the delivery address or adjust the delivery route during the transportation process, it is necessary to obtain the transportation distance based on the real-time trajectory data and destination location data, and then divide it by the real-time vehicle speed to obtain the predicted timeliness data, and further determine whether the predicted timeliness data can meet the requirements to avoid delays. If it is determined that the timeliness is insufficient, an early warning reminder will be output in a timely manner.

[0031] According to an embodiment of the present invention, it also includes: Obtain emergency command information and corresponding logistics vehicle location data; Processing the logistics vehicle location data in combination with the preset emergency rescue center location data to obtain distance data between the logistics vehicle and the preset emergency rescue center; Sort the distance data from small to large to obtain a list of emergency rescue centers; The emergency instruction information and logistics vehicle location data are sent to the emergency rescue center with the smallest distance data for display.

[0032] It should be noted that in order to provide timely rescue after an accident or failure of a logistics vehicle and to ensure the efficiency and safety of transportation, the logistics center needs to determine the nearest rescue center based on the real-time location of the logistics vehicle after receiving the emergency command issued by the logistics vehicle, and send the emergency command information including the failure or accident to the determined rescue center for display, so as to facilitate more targeted rescue.

[0033] According to an embodiment of the present invention, it also includes: Get real-time Hall voltage; Comparing the real-time Hall voltage with a preset reference Hall voltage to obtain a Hall voltage deviation rate; Comparing the Hall voltage deviation rate with a preset Hall voltage deviation threshold to obtain the door opening and closing state; If the Hall voltage deviation rate is less than or equal to a preset Hall voltage deviation threshold, the door opening and closing state is determined to be the door closed; If the Hall voltage deviation rate is greater than a preset Hall voltage deviation threshold, the door opening and closing state is determined to be the door open, and a warning response is output.

[0034] It should be noted that during the transportation process, if the door of the logistics vehicle is abnormally opened, it will cause the loss or damage of the goods or change the transportation environment of the compartment. The real-time Hall voltage is obtained by real-time monitoring through the Hall sensors installed on the compartment doors and door frames, and compared with the preset reference Hall voltage to obtain the Hall voltage deviation rate, and then compared with the preset Hall voltage deviation threshold to obtain the door opening and closing state. In this embodiment, the preset Hall voltage deviation threshold is set to (0, 0.05], (0.05, 1], corresponding to the door closed and the door opened, respectively. For example, the real-time Hall voltage obtained is 2.7v, and the preset reference Hall voltage is 2.5v. (2.7-2.5) / 2.5=0.08 is the Hall voltage deviation rate. If it is greater than the preset Hall voltage deviation threshold, the door opening and closing state is determined to be the door open, and an early warning response is output.

[0035] It is worth mentioning that according to an embodiment of the present invention, it also includes: Obtain real-time load data of logistics vehicles; Comparing the real-time load data with preset load limit data; If the real-time load data is greater than the preset load limit data, the real-time load data and the preset load limit data are processed to obtain the overload rate; Compare the overload rate with a preset overload evaluation threshold to obtain an overload level; If the overload rate is less than or equal to the preset overload assessment threshold, the overload level is determined to be slight overload; If the overload rate is greater than a preset overload assessment threshold, the overload level is determined to be severe overload.

[0036] It should be noted that when the logistics vehicle is loaded with goods, if the overload is not discovered in time and the vehicle leaves the logistics center, it will affect the transportation efficiency, transportation safety or increase the transportation cost. Therefore, the load sensor pre-installed on the chassis of the logistics vehicle is used to monitor the cargo loading situation in real time. When the real-time load data is less than or equal to the preset load limit data, it indicates that there is no overload. If the real-time load data is greater than the preset load limit data, the overload rate is further calculated. For example, if the real-time load data is 11 tons and the preset load limit data is 10 tons, then (11-10) / 10=0.1 is the overload rate. Finally, the obtained overload rate is compared with the preset overload evaluation threshold to obtain the overload level. In this embodiment, the preset overload evaluation threshold is 0.1. For example, if the obtained overload rate is 0.05, which is less than the preset overload evaluation threshold, the overload level is determined to be slightly overloaded. If the obtained overload rate is 0.15, which is greater than the preset overload evaluation threshold, the overload level is determined to be severely overloaded.

[0037] It is worth mentioning that according to an embodiment of the present invention, it also includes: Obtain communication data between logistics vehicles and base stations in different driving scenarios, including real-time signal strength data, real-time data transmission rate, and communication stability data; Processing the real-time signal strength data, the real-time data transmission rate, and the communication stability data to obtain a first communication quality evaluation index corresponding to the driving scenario; Performing weighted sum processing on the first communication quality evaluation index to obtain a second communication quality evaluation index; Comparing the second communication quality evaluation index with a preset communication quality requirement index to obtain a communication quality evaluation relative value; Compare the communication quality evaluation relative value with the preset communication stability threshold to obtain the communication connection status; If the communication quality evaluation relative value is less than or equal to the preset communication stability threshold, the communication connection state is determined to be communication unqualified; If the communication quality evaluation relative value is greater than a preset communication stability threshold, the communication connection state is determined to be communication qualified.

[0038] It should be noted that the present invention adopts the Star Flash technology for data interaction processing. The transmission quality of data transmission directly affects the accuracy, timeliness and stability of data interaction. The logistics vehicle will pass through different driving scenarios such as urban roads, highways, mountainous areas and logistics parks during transportation. Therefore, it is necessary to test the communication quality between the logistics vehicle and the logistics base station in different driving scenarios, and calculate and obtain the first communication quality evaluation index in each driving scenario; The calculation formula of the first communication quality evaluation index is: ; in, It is the first communication quality evaluation index. , , They are real-time signal strength data, real-time data transmission rate and communication stability data. , , is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset logistics and transportation monitoring platform); The obtained first communication quality evaluation index is then weighted and summed to obtain a second communication quality evaluation index. The corresponding weight values ​​corresponding to different scenarios are obtained by querying the preset logistics and transportation monitoring platform, and compared with the preset communication quality requirement index to obtain a communication quality evaluation relative value. For example, the second communication quality evaluation index is 8, and the preset communication quality requirement index is 10, then 8 / 10=0.8 is the communication quality evaluation relative value. Finally, the threshold is compared with the preset communication stability threshold to obtain the communication connection state. In this embodiment, the preset communication stability threshold is set to (0, 0.9], (0.9, 1], which respectively correspond to communication failure and communication qualification. For example, if the obtained communication quality evaluation relative value is 0.8, which is less than the preset communication stability threshold, the communication connection state is determined to be communication failure. If the obtained communication quality evaluation relative value is 0.95, which is greater than the preset communication stability threshold, the communication connection state is determined to be communication qualification.

[0040] It should be noted that during the transportation process, logistics vehicles should monitor the vehicle condition and the status of the goods in the carriage in real time. The present invention utilizes the low latency, high transmission rate, high concurrency and high-precision positioning advantages of Star Flash technology to improve logistics efficiency and safety. First, the vehicle operation data and carriage operation data of the logistics vehicle are obtained through the Star Flash terminal device installed on the logistics vehicle and including a variety of sensing sensors.

Then, further processing is performed to obtain the operation compliance evaluation index of the logistics vehicle. Finally, the operating status of the logistics vehicle is accurately determined through threshold comparison.

Then, the obtained working condition stability deviation rate and carriage compliance deviation rate are processed to obtain the operation compliance evaluation index of the logistics vehicle; The calculation formula of the operation compliance evaluation index is: ; in, To run the compliance assessment index, , They are the working condition stability deviation rate and the carriage compliance deviation rate, , It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset logistics and transportation monitoring platform).

[0045] According to an embodiment of the present invention, the step of comparing the operation compliance evaluation index with a preset operation evaluation threshold to obtain the operation status of the logistics vehicle includes: Comparing the operation compliance evaluation index with a preset operation compliance benchmark index to obtain an operation compliance relative value; Compare the relative value of the operational compliance with a preset operational evaluation threshold to obtain the operational status of the logistics vehicle; If the relative value of the operation compliance is less than or equal to the preset operation evaluation threshold, the operation state of the logistics vehicle is determined to be an abnormal state; If the relative value of the operation compliance is greater than a preset operation evaluation threshold, the operation status of the logistics vehicle is determined to be normal.

[0046] It should be noted that in order to determine the operating status of the logistics vehicle, the obtained operating compliance evaluation index is compared with the preset operating compliance benchmark index to obtain the relative value of the operating compliance. For example, the operating compliance evaluation index is 7, and the preset operating compliance benchmark index is 10, then 7 / 10=0.7 is the relative value of the operating compliance, and then the threshold is compared with the preset operating evaluation threshold to obtain the operating status of the logistics vehicle. In this embodiment, the preset operating evaluation threshold is set to (0, 0.85], (0.85, 1], corresponding to the abnormal state and the normal state, respectively. For example, if the obtained relative value of the operating compliance is 0.7, which is less than the preset operating evaluation threshold, the operating status of the logistics vehicle is determined to be an abnormal state. If the obtained relative value of the operating compliance is 0.9, which is greater than the preset operating evaluation threshold, the operating status of the logistics vehicle is determined to be a normal state.

[0047] According to an embodiment of the present invention, it also includes: Obtain real-time trajectory data and real-time speed of logistics vehicles; Obtain the dispatch instruction information of the logistics vehicle, and extract the destination location data and time efficiency demand data according to the dispatch instruction information; Processing the real-time trajectory data and the destination location data in combination with the real-time vehicle speed to obtain predicted timeliness data; If the predicted timeliness data is less than or equal to the timeliness demand data, no warning is output; If the predicted timeliness data is greater than the timeliness requirement data, an insufficient timeliness warning is output.

[0048] It should be noted that when a logistics vehicle receives a dispatch instruction to temporarily change the delivery address or adjust the delivery route during the transportation process, it is necessary to obtain the transportation distance based on the real-time trajectory data and destination location data, and then divide it by the real-time vehicle speed to obtain the predicted timeliness data, and further determine whether the predicted timeliness data can meet the requirements to avoid delays. If it is determined that the timeliness is insufficient, an early warning reminder will be output in a timely manner.

[0049] According to an embodiment of the present invention, it also includes: Obtain emergency command information and corresponding logistics vehicle location data; Processing the logistics vehicle location data in combination with the preset emergency rescue center location data to obtain distance data between the logistics vehicle and the preset emergency rescue center; Sort the distance data from small to large to obtain a list of emergency rescue centers; The emergency instruction information and logistics vehicle location data are sent to the emergency rescue center with the smallest distance data for display.

[0050] It should be noted that in order to provide timely rescue after an accident or failure of a logistics vehicle and to ensure the efficiency and safety of transportation, the logistics center needs to determine the nearest rescue center based on the real-time location of the logistics vehicle after receiving the emergency command issued by the logistics vehicle, and send the emergency command information including the failure or accident to the determined rescue center for display, so as to facilitate more targeted rescue.

[0051] According to an embodiment of the present invention, it also includes: Get real-time Hall voltage; Comparing the real-time Hall voltage with a preset reference Hall voltage to obtain a Hall voltage deviation rate; Comparing the Hall voltage deviation rate with a preset Hall voltage deviation threshold to obtain the door opening and closing state; If the Hall voltage deviation rate is less than or equal to a preset Hall voltage deviation threshold, the door opening and closing state is determined to be the door closed; If the Hall voltage deviation rate is greater than a preset Hall voltage deviation threshold, the door opening and closing state is determined to be the door open, and a warning response is output.

[0052] It should be noted that during the transportation process, if the door of the logistics vehicle is abnormally opened, it will cause the loss or damage of the goods or change the transportation environment of the compartment. The real-time Hall voltage is obtained by real-time monitoring through the Hall sensors installed on the compartment doors and door frames, and compared with the preset reference Hall voltage to obtain the Hall voltage deviation rate, and then compared with the preset Hall voltage deviation threshold to obtain the door opening and closing state. In this embodiment, the preset Hall voltage deviation threshold is set to (0, 0.05], (0.05, 1], corresponding to the door closed and the door opened, respectively. For example, the real-time Hall voltage obtained is 2.7v, and the preset reference Hall voltage is 2.5v. (2.7-2.5) / 2.5=0.08 is the Hall voltage deviation rate. If it is greater than the preset Hall voltage deviation threshold, the door opening and closing state is determined to be the door open, and an early warning response is output.

[0053] It is worth mentioning that according to an embodiment of the present invention, it also includes: Obtain real-time load data of logistics vehicles; Comparing the real-time load data with preset load limit data; If the real-time load data is greater than the preset load limit data, the real-time load data and the preset load limit data are processed to obtain the overload rate; Compare the overload rate with a preset overload evaluation threshold to obtain an overload level; If the overload rate is less than or equal to the preset overload assessment threshold, the overload level is determined to be slight overload; If the overload rate is greater than a preset overload assessment threshold, the overload level is determined to be severe overload.

[0054] It should be noted that when the logistics vehicle is loaded with goods, if the overload is not discovered in time and the vehicle leaves the logistics center, it will affect the transportation efficiency, transportation safety or increase the transportation cost. Therefore, the load sensor pre-installed on the chassis of the logistics vehicle is used to monitor the cargo loading situation in real time. When the real-time load data is less than or equal to the preset load limit data, it indicates that there is no overload. If the real-time load data is greater than the preset load limit data, the overload rate is further calculated. For example, if the real-time load data is 11 tons and the preset load limit data is 10 tons, then (11-10) / 10=0.1 is the overload rate. Finally, the obtained overload rate is compared with the preset overload evaluation threshold to obtain the overload level. In this embodiment, the preset overload evaluation threshold is 0.1. For example, if the obtained overload rate is 0.05, which is less than the preset overload evaluation threshold, the overload level is determined to be slightly overloaded. If the obtained overload rate is 0.15, which is greater than the preset overload evaluation threshold, the overload level is determined to be severely overloaded.

[0055] It is worth mentioning that according to an embodiment of the present invention, it also includes: Obtain communication data between logistics vehicles and base stations in different driving scenarios, including real-time signal strength data, real-time data transmission rate, and communication stability data; Processing the real-time signal strength data, the real-time data transmission rate, and the communication stability data to obtain a first communication quality evaluation index corresponding to the driving scenario; Performing weighted sum processing on the first communication quality evaluation index to obtain a second communication quality evaluation index; Comparing the second communication quality evaluation index with a preset communication quality requirement index to obtain a communication quality evaluation relative value; Compare the communication quality evaluation relative value with the preset communication stability threshold to obtain the communication connection status; If the communication quality evaluation relative value is less than or equal to the preset communication stability threshold, the communication connection state is determined to be communication unqualified; If the communication quality evaluation relative value is greater than a preset communication stability threshold, the communication connection state is determined to be communication qualified.

[0056] It should be noted that the present invention adopts the Star Flash technology for data interaction processing. The transmission quality of data transmission directly affects the accuracy, timeliness and stability of data interaction. The logistics vehicle will pass through different driving scenarios such as urban roads, highways, mountainous areas and logistics parks during transportation. Therefore, it is necessary to test the communication quality between the logistics vehicle and the logistics base station in different driving scenarios, and calculate and obtain the first communication quality evaluation index in each driving scenario; The calculation formula of the first communication quality evaluation index is: ; in, It is the first communication quality evaluation index. , , They are real-time signal strength data, real-time data transmission rate and communication stability data. , , is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset logistics and transportation monitoring platform); The obtained first communication quality evaluation index is then weighted and summed to obtain a second communication quality evaluation index. The corresponding weight values ​​corresponding to different scenarios are obtained by querying the preset logistics and transportation monitoring platform, and compared with the preset communication quality requirement index to obtain a communication quality evaluation relative value. For example, the second communication quality evaluation index is 8, and the preset communication quality requirement index is 10, then 8 / 10=0.8 is the communication quality evaluation relative value. Finally, the threshold is compared with the preset communication stability threshold to obtain the communication connection state. In this embodiment, the preset communication stability threshold is set to (0, 0.9], (0.9, 1], which respectively correspond to communication failure and communication qualification. For example, if the obtained communication quality evaluation relative value is 0.8, which is less than the preset communication stability threshold, the communication connection state is determined to be communication failure. If the obtained communication quality evaluation relative value is 0.95, which is greater than the preset communication stability threshold, the communication connection state is determined to be communication qualification.
