[0079] This embodiment combines a vehicle dispatching and optimization management device with a vehicle management platform to achieve vehicle dispatching and optimization management. The device of this embodiment is equipped with a vehicle sensor and an RTK positioning module. The device does not need to communicate with the vehicle's onboard computer. All vehicle information comes from the device's own sensor, and the vehicle model can be installed without restriction. In addition, this embodiment uses RTK positioning as a supplement to GPS positioning to achieve centimeter-level precision positioning.

Using RTK in this embodiment can significantly solve the problem of inaccurate vehicle positioning and easy interference in positioning. Its high precision, real-time and high efficiency make the vehicle dispatching and optimization management system of this embodiment have a wider range of application scenarios.
[0080] Reference Figure 2 , this embodiment provides an example structural diagram of a system for vehicle scheduling and optimization management.
[0081] Specifically, the vehicle dispatching and optimization management system of this embodiment includes a vehicle management platform and multiple vehicle dispatching and optimization management devices, which include a controller and a sensor, wherein the controller may include a CPU module, a power module, an RTK module, a GPS module, a 4G module (network module), a Bluetooth module, an interface module and an acceleration detection module, and the sensor may include a tire pressure sensor, an oil level sensor and a camera.
[0082] The vehicle management platform can be used to display and process the data transmitted by the device and issue control and scheduling instructions to the controller in the device. The CPU module in the controller can be used to process data acquisition operations from various sensors and positioning modules, as well as control the work of other hardware modules. The performance of the CPU module directly affects the processing speed and response capability of the entire system. In this embodiment, the cost-effective Allwinner V3S chip is used as the CPU module. The power module provides stable power support for the device. The power module includes 5V and 3V power supplies, a DC 5V backup battery, and a voltage acquisition module, so that the device can still work normally when the power fails or the voltage fluctuates. The reliability of the power module is the basis for ensuring the stable operation of the device. The RTK module receives the positioning information of the satellite and realizes high-precision positioning through differential technology. The RTK module uses the Dreamcore MXT906B module to communicate with the base station, receive the differential data sent by the base station, and perform real-time corrections on the received satellite signals to achieve high-precision positioning; the RTK module is the core component for achieving high-precision positioning, which is crucial for vehicle scheduling and optimization management. The GPS module is used as a positioning unit that works in conjunction with the RTK positioning module. When the vehicle is on a highway or in a place where the RTK base station is not covered, the GPS module is used as the main positioning module to locate the latitude and longitude for vehicle management. The 4G module is used for data communication between the vehicle management platform or other vehicles, transmitting the vehicle's real-time position, speed, status and other information to the dispatching platform, and receiving instructions and dispatching information from the vehicle management platform; the stability and speed of the 4G module directly affect the real-time and accuracy of vehicle dispatching and optimization management. The present invention uses China Mobile's ML307 as the 4G module. The Bluetooth module uses BK3633, which is used for communication between the controller and external devices or sensors; the interface module has RJ45 and RS485 interfaces for accessing external cameras or other peripherals. The acceleration detection module is used to measure the acceleration of the vehicle and provide information on the vehicle's motion status. The tire pressure sensor is installed in an external manner at the tire inflation port to monitor the pressure changes inside the tire in real time and transmit this information to the controller; when the tire pressure is abnormal, the sensor will issue an alarm in time to remind the driver or the vehicle management platform to take corresponding measures. The fuel level sensor is installed on the fuel tank cap to monitor the fuel level changes in the tank in real time and transmit this information to the controller; when the fuel level is insufficient, the sensor will issue an alarm in time. The camera communicates with the controller via the RJ45 network port. When the controller sends abnormal information to the vehicle management platform, the vehicle management platform can call the camera to check the status of the vehicle so as to take emergency measures in time.
[0083] More specifically, the following describes the vehicle management platform transmitting data to the device, displaying data, and transmitting instructions to the device.
[0084] 1. The vehicle management platform transmits a wide variety of data to the device, mainly covering:
[0085] 1. Basic vehicle information, including license plate number, vehicle brand, type, color, frame number, engine number, number of seats, displacement and emission standards, etc. These data are used for vehicle identification and attribute management.
[0086] 2. Location information: vehicle location data obtained in real time through the GPS system, including longitude, latitude, speed, direction, etc., which is used to monitor vehicle dynamics in real time.
[0087] 3. Status information, such as whether the vehicle is started, fuel remaining, battery status, door and window status, etc., is used to evaluate the safety and availability of the vehicle.
[0088] 4. Operational data, such as mileage, fuel consumption, driving time, driving routes, etc., are used to analyze vehicle operating efficiency and costs.
[0089] 2. Vehicle management platform displays data: The vehicle management platform displays the transmitted data through an intuitive and easy-to-use interface, including: map interface, data report, and dashboard.
[0090] 3. The vehicle management platform supports the remote issuance of multiple commands to the device to achieve remote management and control of the vehicle. Common commands and functions include:
[0091] Lock / Unlock Command: Improve vehicle security by sending commands to remotely lock or unlock the vehicle. For example, if the vehicle is stolen or lost, the vehicle can be remotely locked to prevent illegal use.
[0092] Immediate feedback command: Requires the vehicle to immediately feedback the current operating status data, so that the manager can understand the vehicle status in real time.
[0093] Timed feedback command: Set the vehicle to send back operating data at a certain interval (such as 60 seconds) to continuously monitor vehicle dynamics.
[0094] Vehicle photo command: After the photo command is issued, the vehicle camera immediately takes photos of the driver and the surrounding environment to monitor the driver's behavior and vehicle safety.
[0095] Vehicle mileage reset command: used for mileage statistics within a certain period of time, and can remotely reset the GPS vehicle mileage.
[0096] Remote restart command: When a GPS terminal fails, a command is sent to restart the terminal and restore it to normal working state.
[0097] Alarm clearing command: In the case of some terminal alarms, alarms that cannot be handled by alarm processing need to be cleared by issuing commands, such as antenna open circuit alarms.
[0098] Next, the workflow of the vehicle dispatching and optimization management system of this embodiment is described.
[0099] The vehicle dispatching and optimization management device of this embodiment can be installed in the vehicle cab and powered by the 12V power supply on the vehicle. The device has a built-in positioning module, and the matching sensors are installed on the fuel tank cap and the tire inflation hole respectively. The working process of the system is as follows:
[0100] 1. Device startup and initialization.
[0101] The power supply is started to provide a stable power supply for the entire device, so that each hardware module can work normally. The CPU module is responsible for initializing each hardware module and loading the corresponding drivers and applications. At the same time, the vehicle management platform is started and initialized, ready to receive and process data from each hardware module.
[0102] 2. Data collection and transmission.
[0103] The GPS module starts to receive signals from GPS satellites and calculates the absolute position information of the vehicle (longitude, latitude, altitude, etc.). The RTK module uses the carrier phase observation of the Beidou satellite to remove most of the errors in the observation data of the mobile station by differential means to achieve high-precision (decimeter or even centimeter level) positioning. The RTK module is usually used in conjunction with the GPS module and switched according to the vehicle speed. When the speed is greater than the preset speed threshold, such as 10 kilometers per hour or there is no RTK signal coverage, GPS positioning is used. When the vehicle speed is slow or the vehicle reaches a critical position, RTK centimeter-level precise positioning is used.
[0104] The acceleration detection module monitors the acceleration changes of the vehicle in real time and is used to determine the driving status of the vehicle (such as sudden acceleration, sudden braking, etc.). The tire pressure sensor monitors the tire pressure in real time to ensure that the tire is in normal condition and improve driving safety. The fuel level sensor monitors the fuel level in the fuel tank and provides the driver with accurate fuel level information to avoid driving problems caused by insufficient fuel. The camera automatically starts in abnormal situations, such as sudden braking, insufficient fuel, and deviation from the planned path, to capture image information around the vehicle for driving records, safety monitoring, etc.
[0105] 3. Data processing and analysis.
[0106] The CPU module receives the data transmitted by each hardware module, performs preprocessing and analysis, extracts useful information and sends it to the remote platform according to the communication format of the vehicle management platform.
[0107] 4. Data transmission.
[0108] After the CPU completes data processing, it uses the 4G module to transmit vehicle location, status and other information to the vehicle management platform in real time through the 4G network.
[0109] 5. Information display and remote control.
[0110] The vehicle management platform displays the processed data to users in a graphical or textual manner, such as vehicle location, driving speed, fuel level information, etc. Users can make vehicle dispatch plans based on the actual situation of the vehicle.
[0111] The beneficial effects of this embodiment include:
[0112] The RTK module (realizing real-time dynamic carrier phase differential technology) of this embodiment is combined with vehicle debugging optimization management, which can solve the problem of inaccurate vehicle positioning to a large extent. The RTK module of this embodiment has significant advantages in vehicle scheduling and optimization management due to its high precision, real-time and high efficiency. The RTK module of this embodiment receives information from satellites through ground receiving equipment, and uses the differential positioning principle to calculate and correct positioning errors in real time, thereby achieving high-precision position positioning and navigation. The positioning accuracy of centimeters or even millimeters can be provided in real time, and is not seriously affected by environmental factors such as weather and terrain. It reduces the interference caused by the reflection and obstruction of satellite signals by objects such as high-rise buildings and metal buildings in the city, provides accurate position information for vehicle scheduling and optimization management, helps users to grasp the running status of vehicles in real time, improves scheduling efficiency and accuracy, formulates more reasonable path planning schemes, and optimizes vehicle driving routes, which can not only improve transportation efficiency, but also reduce fuel consumption and emissions, and realize green transportation and intelligent scheduling and monitoring of vehicles.
