Technical Field

[0001] This invention relates to the field of new energy truck condition monitoring technology, specifically to a real-time online monitoring system and method for the operating status of new energy trucks. Background Technology

[0002] The operational status of new energy trucks is crucial for fleet management. Operational status monitoring serves two main purposes: providing drivers with information about their vehicles' status and, more importantly, feeding back data to the fleet management backend to facilitate vehicle operation. This necessitates real-time online monitoring capabilities. Current truck operational status monitoring systems are offline, only reflecting the operational status of individual vehicles. Their principle relies on sensor information to display the vehicle's operational status, including remaining mileage, remaining battery power, average operating speed, and average energy consumption, on the driver's dashboard and vehicle operating system.

[0003] The current traditional monitoring systems for new energy trucks have the following main drawbacks:

[0004] (1) It cannot achieve remote online real-time vehicle status monitoring and cannot send data to the back-end fleet operation management system, which is inconvenient for vehicle operation management.

[0005] (2) Drivers can only obtain vehicle status information from the vehicle instrument panel or central control system, and cannot obtain it from their mobile phones, which is inconvenient to use.

[0006] Therefore, there is an urgent need to design a real-time online monitoring system and method for the operating status of new energy trucks to solve the problem of inconvenience in vehicle management and use caused by the inability to monitor the operating status of existing new energy trucks in real time. Summary of the Invention

[0007] To address the problems existing in the prior art, the purpose of this invention is to provide a real-time online monitoring system and method for the operating status of new energy trucks. A corresponding mobile APP page has been developed, which can transmit real-time status information such as total mileage, average speed, remaining battery power, total discharge, and energy consumption over nearly 50km to the backend or the user's mobile phone for display through vehicle-mounted message transmission and wireless transmission. This makes it convenient for users and fleet management backends to understand the real-time status of the vehicles, greatly facilitating vehicle management and user operation.

[0008] The technical solution adopted by the present invention to solve its technical problem is: a real-time online monitoring system for the operating status of a new energy truck, including on-board sensors, on-board controller, vehicle CAN bus system, on-board wireless terminal and mobile APP.

The vehicle wireless terminal reads the vehicle's current status information from the vehicle CAN bus system.

[0012] Preferably, the vehicle-mounted wireless terminal transmits data to a mobile terminal APP via wireless signal. The mobile terminal APP calculates the remaining battery power, total mileage, total discharge, average vehicle speed, and energy consumption over approximately 50km using the background data calculation logic.

[0024] like Figure 1 As shown, a real-time online monitoring system for the operating status of a new energy truck includes on-board sensors, an on-board controller, a vehicle CAN bus system, an on-board wireless terminal, and a mobile APP. The on-board sensors are connected to the on-board controller, the on-board controller is connected to the vehicle CAN bus system, the vehicle CAN bus system is connected to the on-board wireless terminal, and the on-board wireless terminal is wirelessly connected to the mobile APP. The mobile APP has built-in computing logic.

[0025] Vehicle sensors include, but are not limited to, speed sensors and battery level detection sensors. Speed ​​sensors collect vehicle speed information, which is a vehicle status information, while battery level detection sensors collect battery level information, which is a vehicle status information.

[0026] The working principle of this invention is as follows: Vehicle status information identified by onboard sensors is sent to the onboard controller in the form of electrical signals. The onboard controller identifies the electrical signals and generates message information. The onboard controller then sends this message information to the vehicle's CAN bus system to inform the vehicle of its current status. The onboard wireless terminal reads the vehicle's current status information from the CAN bus system. The onboard wireless terminal transmits this information wirelessly to a mobile app, displaying the information on the app's screen.

[0031] Example 1:

[0032] The present invention features a real-time online monitoring function for remaining battery power: the battery power detection sensor feeds back the current status of the vehicle battery to the BMS (Battery Management System) in the form of an electrical signal. The BMS compiles this electrical signal and generates a message "Power Battery SOC". This message is transmitted to the vehicle's CAN bus system and read by the vehicle's wireless terminal (Tianxingjian). It is then sent to the user's mobile phone APP via a wireless signal. The mobile phone software uses built-in calculation logic to display the remaining battery power information as a percentage on the mobile phone APP page. The accuracy of the remaining battery power signal is 0.4%, and the information is updated every 200ms to ensure the real-time availability of data for the user.
