Description

Technical Field

[0001] The present invention relates to the technical field of positioning terminals, and in particular to a portable vehicle-mounted positioning terminal system. Background Art

[0002] Traditional fixed positioning terminals are mainly installed by taking power from the vehicle's fuse box and the vehicle's circuit to power the equipment. The wiring method is relatively complicated and requires accurate identification of power lines, oil-off lines, and ACC lines. The locations of these lines vary and require careful search and testing. In addition, tools such as test pens are required during the wiring process to ensure that each line is correctly connected. This process is time-consuming and error-prone. Since the wiring of the positioning terminal needs to be precisely connected to the vehicle's circuit system, improper installation may cause damage to the equipment or vehicle circuits.

[0003] Currently, the vehicle terminals for rental cars are also connected in the same way as conventional on-board positioning terminals, and there is no dedicated system for vehicle application and dispatch management background. Summary of the invention

[0004] The purpose of the present invention is to provide a portable vehicle-mounted positioning terminal system to solve the technical problems that the vehicle terminal of a rental car adopts a relatively complex wiring method of a conventional vehicle-mounted positioning terminal and has no dedicated system for vehicle application and dispatch management background.

[0005] In order to solve the above technical problems, the present invention provides a portable vehicle-mounted positioning terminal system, including a background and a plurality of portable vehicle-mounted positioning terminals connected to the background in communication, the background including a management center data server and a monitoring computer connected to the management center data server, the portable vehicle-mounted positioning terminal including a monitoring terminal host and a terminal positioning module, a power supply module and a data transmission module connected to the monitoring terminal host;

[0006] The power taking module is provided with a power input interface, a power management circuit, a power output interface, a charging circuit and a battery, wherein the power input interface is connected to the power management circuit and the charging circuit, the power management circuit is connected to the battery and the power output interface, the charging circuit is connected to the battery, the power input interface is used to connect to the cigarette lighter interface, USB interface or OBD interface of the vehicle, and the power output interface is used to connect to the monitoring terminal host; the power taking module takes power from the cigarette lighter interface, USB interface or OBD interface of the vehicle through the power input interface, supplies power to the monitoring terminal host, terminal positioning module and data transmission module through the power management circuit and the power output interface, and charges the battery through the charging circuit; the battery is used as a backup power supply, and when the vehicle power fails, the monitoring terminal host, terminal positioning module and data transmission module are supplied with power through the power management circuit and the power output interface;

[0007] The terminal positioning module is used to obtain the positioning information of the vehicle and send it to the monitoring terminal host;

[0008] The monitoring terminal host is used to upload the positioning information to the management center data server through the data transmission module;

[0009] The management center data server is used to receive the positioning information uploaded by the multiple portable vehicle-mounted positioning terminals, and process the positioning information uploaded by the multiple portable vehicle-mounted positioning terminals to obtain vehicle information and positioning information of each vehicle, and obtain corresponding driver information and vehicle manager information based on the vehicle information of each vehicle, and output the vehicle information, positioning information, driver information and vehicle manager information of each vehicle to the monitoring computer for display.

[0010] Compared with the traditional fixed positioning terminal, the portable vehicle-mounted positioning terminal system of the present invention has the following beneficial effects:

[0011] (1) Due to the portable design, there is no need for complicated wiring process. It only needs to be connected through the vehicle's cigarette lighter interface, USB interface or OBD interface, which greatly simplifies the installation steps and reduces the difficulty of installation. The traditional method requires precise docking with the vehicle's circuit system, while the present invention draws power through a standard interface, reducing the risk of damage to the equipment or vehicle circuit due to improper installation. The portable design makes installation faster and can be completed without the need for professionals, saving installation time and labor costs.

[0012] (2) The built-in battery serves as a backup power source. When the vehicle power fails, the positioning terminal can still operate normally, thus improving the reliability of the system.

[0013] (3) By connecting to the backend management center, the vehicle's positioning information can be uploaded in real time. The management center can monitor and dispatch the vehicle in real time, thus improving the efficiency of vehicle management. The data server of the management center can process the information uploaded by multiple portable vehicle-mounted positioning terminals, centrally manage vehicle information, positioning information, driver information and vehicle management officer information, and facilitate data analysis and decision support. It is particularly suitable for scenarios such as rental vehicles that require frequent replacement of vehicle-mounted positioning terminals, providing a more flexible and convenient solution.

[0017] Figure 2 4 is a circuit diagram of a power taking module in an embodiment of the present invention. DETAILED DESCRIPTION

[0018] The detailed description of the accompanying drawings is intended as an illustration of the current embodiments of the present invention and is not intended to represent the only form in which the present invention can be implemented. It should be understood that the same or equivalent functions can be accomplished by different embodiments that are intended to be included in the spirit and scope of the present invention.

[0019] See also Figures 1-2 An embodiment of the present invention provides a portable vehicle-mounted positioning terminal system, including a background and multiple portable vehicle-mounted positioning terminals connected to the background for communication, the background including a management center data server and a monitoring computer connected to the management center data server, the portable vehicle-mounted positioning terminal including a monitoring terminal host and a terminal positioning module, a power supply module and a data transmission module connected to the monitoring terminal host.

[0020] The power taking module is provided with a power input interface, a power management circuit, a power output interface, a charging circuit and a battery. The power input interface is connected to the power management circuit and the charging circuit, the power management circuit is connected to the battery and the power output interface, the charging circuit is connected to the battery, the power input interface is used to connect to the vehicle's cigarette lighter interface, USB interface or OBD interface, and the power output interface is used to connect to the monitoring terminal host; the power taking module draws power from the vehicle's cigarette lighter interface, USB interface or OBD interface through the power input interface, and supplies power to the monitoring terminal host, the terminal positioning module and the data transmission module through the power management circuit and the power output interface. The battery is charged through the charging circuit; the battery is used as a backup power supply, and when the vehicle power fails, the monitoring terminal host, the terminal positioning module and the data transmission module are powered through the power management circuit and the power output interface; specifically, when the vehicle is started and the power system is working normally, the power taking module takes power from the vehicle's cigarette lighter interface, USB interface or OBD interface through the power input interface, and the power management circuit distributes the acquired power to the monitoring terminal host, the terminal positioning module and the data transmission module, and charges the battery through the charging circuit at the same time. If the vehicle power system suddenly fails, the power taking module will automatically switch to the backup battery for power supply, ensuring that the entire positioning system continues to operate and the service will not be interrupted due to power problems.

[0021] The terminal positioning module is used to obtain the vehicle's positioning information and send it to the monitoring terminal host; specifically, the terminal positioning module includes one or more positioning sensors, such as GPS (Global Positioning System), GLONASS, Beidou or Wi-Fi, etc., which are used to determine the specific location information of the vehicle, including longitude, latitude, speed, direction and time, etc.; once the positioning sensor obtains the vehicle's geographic location information, the terminal positioning module will process these data to ensure the accuracy and completeness of the information; the processed positioning information is sent to the monitoring terminal host through the internal communication interface; the monitoring terminal host is the core processing unit of the system, which is responsible for receiving, storing and further processing these positioning data; the terminal positioning module can update the vehicle's positioning information at a certain frequency (such as every second or every minute), thereby realizing real-time monitoring of the vehicle; the terminal positioning module is tightly integrated with the monitoring terminal host, and data is transmitted between them through wired (such as serial port, USB, etc.) or wireless (such as Bluetooth, Wi-Fi, etc.) methods.

[0022] The monitoring terminal host is used to upload the positioning information to the management center data server through the data transmission module.

[0023] The management center data server is used to receive the positioning information uploaded by the multiple portable vehicle-mounted positioning terminals, and process the positioning information uploaded by the multiple portable vehicle-mounted positioning terminals to obtain the vehicle information and positioning information of each vehicle, and obtain the corresponding driver information and vehicle manager information according to the vehicle information of each vehicle, and output the vehicle information, positioning information, driver information and vehicle manager information of each vehicle to the monitoring computer for display; specifically, the management center data server plays the role of central processing and storage in the portable vehicle-mounted positioning terminal system. The management center data server communicates with multiple portable vehicle-mounted positioning terminals through the Internet or a proprietary network. When the portable vehicle-mounted positioning terminal uploads the vehicle's positioning information regularly or in real time, the server will receive these data, including parsing data, verifying the accuracy of data, filtering invalid or erroneous data, etc. During the processing, the server will match the positioning data with the information in the vehicle database to identify the specific vehicle and extract the corresponding vehicle information from the vehicle database, such as vehicle model, license plate number, vehicle status, etc. Based on the vehicle information, the server will further obtain the driver information (such as driver's name, contact information, driving qualifications, etc.) and vehicle manager information (such as vehicle manager's name, contact information, etc.) associated with the vehicle, and integrate the processed vehicle positioning information, vehicle information, driver information and vehicle manager information. The server then outputs this comprehensive information to the display screen of the monitoring computer for the monitoring personnel to view and analyze.

[0024] The monitoring computer is equipped with special monitoring software that can display the vehicle's real-time location, historical trajectory, speed, status, etc. in a graphical interface (such as displaying the vehicle's location on a map) or in a list format. Monitoring personnel can use this information to monitor the vehicle's operating status, perform scheduling management, or respond quickly in an emergency.

[0025] In some embodiments, the monitoring computer is used to receive a vehicle application submitted by a vehicle manager, and submit a vehicle request to the management center data server according to the vehicle application;

[0026] The management center data server is used to receive the vehicle use request, determine the target vehicle according to the vehicle use request, generate a vehicle use work order according to the vehicle information of the target vehicle and distribute it to the corresponding driver, and obtain the order response information replied by the driver. When the driver decides to execute the vehicle use work order, the driver information and the vehicle manager information are associated with the vehicle information and stored locally on the server.

[0027] Specifically, when using a monitoring computer, a vehicle manager (vehicle administrator) can submit a vehicle use application based on actual needs. The vehicle use application includes information such as vehicle use time, destination, and reason for use. After the monitoring computer receives the vehicle use application from the vehicle manager, it will organize this information into a vehicle use request and then send it to the management center data server via the network.

[0028] After receiving a vehicle request, the management center data server will determine the most suitable target vehicle based on the requirements in the request (such as vehicle usage time, location, vehicle type, etc.). The server will consider factors such as the vehicle's current location, status, availability, etc. to select the most suitable vehicle. After determining the target vehicle, the management center data server will generate a vehicle usage work order, which includes vehicle usage details, such as vehicle usage time, destination, vehicle information, etc.

[0029] The server will send the generated vehicle work order to the corresponding driver through SMS, email or mobile application. After receiving the vehicle work order, the driver will decide whether to accept the work order according to his own situation. If the driver decides to perform the vehicle task, he will reply to the order response information in the corresponding way. When the management center data server receives the driver's order response, it will associate the driver information and the vehicle manager information with the vehicle information of the target vehicle. The associated information will be stored locally on the server for subsequent vehicle scheduling, management and record query.

[0030] Through this process, the management center data server not only handles vehicle applications, but also ensures the effective allocation and recording of vehicle tasks. This process improves vehicle dispatch efficiency, ensures the rational use of vehicle and driver resources, and provides detailed records of vehicle usage for easy management and auditing.

[0031] In some embodiments, the vehicle application includes at least the vehicle use time, location, number of users and special needs, and the special needs include vehicle type and comfort requirements.

[0032] Specifically, the vehicle usage time refers to the specific date and time that the user wants to use the vehicle. This information is very important for vehicle scheduling because it helps dispatchers determine whether there are available vehicles at a specific time and how to arrange the allocation and use of the vehicle.

[0033] The pick-up location refers to the pickup point or destination where the user wants the vehicle to arrive. This information is also critical because it affects the selection and dispatch of vehicles, especially if the pick-up location is far from the vehicle storage location or the traffic conditions at the pick-up location require a specific type of vehicle.

[0034] The number of passengers is the number of people expected to ride in the vehicle, and this information is critical for selecting the right size vehicle; for example, if there are more passengers, a van or minibus will need to be dispatched instead of a regular car.

[0035] Special needs refer to additional requirements of the vehicle user on the use of the vehicle, which are not part of the standard service. Special needs include but are not limited to the following:

[0036] Vehicle type: The user needs a specific type of vehicle, such as a luxury sedan, SUV, truck, or other special vehicle, depending on the purpose;

[0037] Comfort requirements: Vehicle users have special requirements for vehicle comfort, such as air conditioning, spacious seats, legroom, specific seat configurations, etc.

[0038] By including these details in the vehicle application, the vehicle manager or vehicle user can more accurately convey their needs, and the management center data server can more effectively match and dispatch the appropriate vehicle based on these needs. This process helps ensure the satisfaction of vehicle users while also improving the efficiency of vehicle dispatch and management.

[0039] In some embodiments, the management center data server is specifically used to receive the vehicle use request, query the vehicle status database according to the vehicle use request, screen out all idle vehicles that meet the vehicle use requirements, and use a vehicle matching algorithm to match all idle vehicles that meet the vehicle use requirements, and select the idle vehicle with the highest matching degree as the target vehicle; the idle vehicle refers to a vehicle that currently has no assigned tasks, is in good maintenance status, and is available within the vehicle use time range.

[0040] Specifically, the management center data server first receives a vehicle request from the monitoring computer. This request contains key information such as the time, location, number of people using the vehicle, and special needs. The server then queries the vehicle status database, which contains the current status information of all vehicles, such as whether the vehicle is idle, maintenance status, location, vehicle type and configuration, etc. The server selects all eligible idle vehicles from the vehicle status database according to the requirements in the vehicle request.

[0041] An idle vehicle is defined as follows:

[0042] No task assigned: The vehicle is not currently assigned to any vehicle task.

[0043] Well-maintained: The vehicle has completed necessary maintenance and is in good operating condition.

[0044] Available within the vehicle usage time range: The vehicle is available within the time range specified in the vehicle usage request and has no other scheduled tasks.

[0045] Through the vehicle matching algorithm, the server will select the idle vehicle with the highest matching degree as the target vehicle. The matching degree is calculated based on the degree to which the vehicle meets the various requirements in the vehicle request.

[0046] Through this process, the management center data server can intelligently select the most suitable vehicle to meet the vehicle request, ensuring the effective use of vehicle resources and the satisfaction of vehicle users. This method is more efficient and accurate than manual vehicle selection, especially when there are a large number of vehicles and complex vehicle needs.

[0047] In some embodiments, the management center data server is specifically used to calculate the score of idle vehicles based on the matching degree between vehicle type and vehicle use demand, the distance between the vehicle's current location and the vehicle use location, the matching degree between the vehicle's expected idle time and the vehicle use time, the vehicle's maintenance record and operating status, and the driver's qualifications and availability, and select the idle vehicle with the highest score as the target vehicle.

[0048] Specifically, when the management center data server matches an idle vehicle for a car request, it uses a comprehensive scoring system to determine the most suitable vehicle. The following are several key factors that the server considers when calculating the idle vehicle score and their explanations:

[0049] The matching degree between vehicle type and vehicle use requirements: The server will evaluate whether the vehicle type (such as sedan, SUV, truck, etc.) meets the special requirements in the vehicle use application. If the vehicle type highly matches the requirements, the score will be higher.

[0050] The distance between the vehicle's current location and the pick-up location: The server will calculate the distance between the vehicle's current location and the pick-up location. The closer the distance, the higher the vehicle's score, as this can reduce pick-up time and improve efficiency.

[0051] The matching degree between the estimated idle time of the vehicle and the time of use: The server will consider whether the estimated idle time of the vehicle is consistent with the time of the vehicle use request. If the idle time of the vehicle coincides with the time of use, and the vehicle has no other scheduled tasks during the time of use, the score will be higher.

[0052] Vehicle maintenance record and operating condition: The server will check the vehicle's maintenance record to ensure that the vehicle is regularly maintained and has no major failure history. A vehicle in good operating condition will receive a higher score.

[0053] Driver qualifications and availability: The server also considers whether the driver's qualifications meet the vehicle requirements (such as specific driving experience, skills or certifications) and the driver's availability during the vehicle usage time. The higher the driver's qualifications and the better the availability, the higher the vehicle's score will be.

[0054] The management center data server will calculate a comprehensive score for each idle vehicle based on the above factors. The scoring system will assign different weights to each factor to reflect their importance in the overall matching. Finally, the server will select the idle vehicle with the highest score as the target vehicle and assign it to the vehicle request. Through this comprehensive scoring method, the management center data server can more accurately and fairly select the most suitable vehicle to meet the vehicle demand, thereby optimizing the vehicle scheduling process and improving service quality.

[0055] In some embodiments, the management center data server is specifically used to obtain the vehicle information, driver information and detailed information of the vehicle use request of the target vehicle, fill the vehicle information, driver information and detailed information of the vehicle use request of the target vehicle into the corresponding fields of the predefined work order template, and generate a vehicle use work order with a unique identification code; the vehicle information includes license plate number, model, color and number of seats, and the driver information includes name, contact information and driver's license number.

[0056] Specifically, after processing the vehicle request and determining the target vehicle, the management center data server will perform the following steps to generate a vehicle work order:

[0057] The server first needs to collect the following information:

[0058] Vehicle information of the target vehicle: including license plate number, model, color, and number of seats, etc. This information is obtained from the vehicle status database;

[0059] Driver information: including the driver's name, contact information and driver's license number, etc. This information is obtained from the driver information database;

[0060] Detailed information on the vehicle request: including the time, location, number of users, special needs, etc. This information comes from the vehicle application submitted by the vehicle manager or the user.

[0061] Fill in the work order template: The server will fill in the collected vehicle information, driver information and car request details into the predefined work order template; the work order template is a pre-designed document or spreadsheet that contains all the necessary information fields required to perform the car use task. Each information field has a clear label, such as "license plate number", "car model", "driver name", etc. The server will fill in the corresponding information into the correct position based on these labels.

[0062] Generate a vehicle use work order: Once all the necessary information is filled in the work order template, the server will generate a vehicle use work order with a unique identification code. This unique identification code is used to distinguish different vehicle use work orders for easy tracking and management.

[0063] The vehicle work order is a key document for vehicle dispatch and task execution. It contains all the information required to execute the vehicle task, ensuring the clear communication and recording of the task. Through this process, the management center data server not only ensures that the detailed information of the vehicle request is accurately recorded, but also provides a standardized process to generate and manage vehicle work orders. Such a process helps to improve the efficiency of vehicle dispatch and management, and also provides a clear guide for drivers and vehicle users to ensure the smooth progress of vehicle services.

[0064] In some embodiments, the management center data server is specifically used to update the work order status to assigned if the driver confirms the order, and record the driver's confirmation information. If the driver refuses or fails to confirm within the specified time, the vehicle matching algorithm is re-executed to select the next optimal vehicle and repeat the steps of generating a new work order and dispatching.

[0065] Specifically, when the management center data server processes the driver's response to the vehicle work order, it will perform the following steps:

[0066] When the driver receives the vehicle work order and confirms to perform the task, they will feedback the confirmation information to the management center data server through some means (such as mobile application, text message or phone call).

[0067] After receiving the driver's confirmation, the server will perform the following operations:

[0068] The server updates the status of the work order from "pending assignment" or "dispatched" to "assigned", indicating that the work order has been accepted by the driver and the vehicle has been assigned to the specific vehicle request; the server will record the driver's confirmation information, including confirmation time, confirmation method, etc., for subsequent tracking and auditing.

[0069] If the driver refuses to accept the order, or does not confirm the order within the specified time, the server will consider the work order not accepted. In this case, the server needs to re-execute the vehicle matching algorithm to find the next best vehicle to meet the vehicle request. This is because the driver is unable to perform the task for various reasons (such as not being in the service area, having other tasks, etc.); or the driver did not respond within the specified time because they did not check the work order in time or could not complete the task within the required time.

[0070] The server will rerun the vehicle matching algorithm based on the latest information in the vehicle status database to filter out idle vehicles that meet the vehicle requirements. The server will select the second most matching vehicle (or the next best vehicle) as the new target vehicle and repeat the steps of generating a new work order, including filling in the work order template and assigning the work order to the new driver. This process will continue until a driver who accepts the work order is found or all vehicles have been tried.

[0071] Through this mechanism, the management center data server can ensure that vehicle requests are met and quickly find alternatives even when the preferred driver is unable to perform the task, thereby maintaining the flexibility and reliability of the vehicle dispatch system.

[0072] In some embodiments, the management center data server is specifically used to process the collected vehicle positioning information, including real-time calculation of vehicle speed, driving direction, and mileage; it is also used to perform data analysis on historical data and generate vehicle driving reports and fuel consumption statistics.

[0073] Specifically, the server calculates the vehicle's moving speed between two positioning points through the received continuous positioning information (including latitude, longitude and timestamp), which can be calculated by the following formula: speed = distance / time; where distance is the straight-line distance between the two positioning points, and time is the time difference from one positioning point to another.

[0074] The server can calculate the vehicle's driving direction based on the vehicle's continuous position changes. This is achieved by comparing the longitude and latitude of the two previous and next position points, and can be converted into an azimuth (such as 30 degrees north by east).

[0075] The server accumulates the distance the vehicle moves over a period of time to obtain the total mileage, which requires continuous distance calculation and summation for all positioning points of the vehicle.

[0076] The server processes the historical positioning data and generates vehicle driving reports, which include:

[0077] Driving time: the total driving time of the vehicle and the driving time of each segment of the journey.

[0078] Driving route: The historical driving path of the vehicle can be visualized on a map.

[0079] Stops: The locations and times where vehicles stop, used to analyze common stop locations or unusual stops.

[0080] If the vehicle is equipped with corresponding sensors, the server can combine positioning data and other sensor data (such as fuel level sensors) to calculate the vehicle's fuel consumption. The server will generate a fuel consumption statistical report, including the fuel consumption of each trip, total fuel consumption, average fuel consumption, etc., to help fleet managers monitor the fuel efficiency of vehicles.

[0081] Through these processing and analysis, the management center data server not only provides real-time monitoring of vehicles, but also provides in-depth insights for fleet managers to help them optimize vehicle usage, reduce operating costs, improve vehicle maintenance efficiency, and ensure driver safety. These data can also be used for compliance reporting, insurance claims processing, and long-term vehicle performance analysis.

[0082] In some embodiments, the software system of the monitoring computer is designed with a user interface for displaying vehicle information;

[0083] The user interface includes a map view, a list view, and a chart;

[0084] Displaying the real-time location of the vehicle in the map view, including the vehicle icon, license plate number, and speed;

[0085] Displaying basic vehicle information, driver information, vehicle manager information, and the latest status of the vehicle in the list view;

[0086] The driving statistics of the vehicle are displayed in the chart, including mileage, fuel consumption, etc.

[0087] Specifically, the software system of the monitoring computer provides users with an intuitive and feature-rich platform to monitor and manage the vehicle by designing a user interface (UI).

[0088] (1) Map view:

[0089] The map view uses geographic information system (GIS) technology to display the real-time location of the vehicle. This is achieved by placing icons representing the vehicles on the map. Each vehicle has a specific icon on the map so that users can quickly identify it. The license plate number is displayed next to the vehicle icon so that users know which vehicle it is. The map view also shows the vehicle's current speed, which is calculated in real time from the positioning data.

[0090] (2) List view:

[0091] Basic information: List view displays the basic information of the vehicle in a table or list format, such as license plate number, model, color, number of seats, etc.

[0092] Driver information: including driver's name, contact information, driver's license number, etc.

[0093] Vehicle manager information: Displays the contact information of the vehicle manager who is responsible for managing the vehicle.

[0094] Latest status: Displays the latest status of the vehicle, such as "driving", "stopped", "under maintenance", etc., as well as other relevant information, such as the last update time, current location, etc.

[0095] (3) Charts:

[0096] Driving Statistics: The Chart view uses graphs and charts to display the driving statistics of the vehicle, including:

[0097] Mileage: The total mileage of a vehicle within a certain period of time, which can be daily, weekly, monthly or annual statistics.

[0098] Fuel consumption: vehicle fuel consumption, including total fuel consumption, average fuel consumption, etc.

[0099] Other statistics: In addition to mileage and fuel consumption, the chart also displays other statistical information, such as driving time, speed distribution, number of stops, etc.

[0100] Through this multi-view interface design, the software system of the monitoring computer provides users with a comprehensive vehicle monitoring solution. Users can select different views to obtain information according to their needs, for example, quickly locate the vehicle through the map view, view detailed information through the list view, and analyze the long-term performance and efficiency of the vehicle through the chart view. Such a design improves the user's work efficiency and makes vehicle monitoring and management more intuitive and convenient.

[0101] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
