[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further explained below with reference to the accompanying drawings and embodiments.

[0026] To facilitate understanding of the technical solution of the present invention, the professional terms involved are now explained.

[0027] Remote debugging: Based on wireless communication technology, the local controller is connected through a wireless gateway to achieve remote online monitoring, program changes, and remote debugging of the equipment.

[0028] CAN bus technology: a technology used in production sites to implement bidirectional serial multi-node digital communication between measurement and control equipment.

[0029] Example:

[0030] like Figure 1As shown, this embodiment proposes a portable remote debugging operation box, primarily for use by debuggers and field service personnel during vehicle debugging and maintenance. It comprises a box 1, components integrated within the box 1, and a debugging interface prefabricated on the surface of the box 1. These components include, but are not limited to, a circuit breaker 2, a switching power supply 3, a wireless gateway 4, terminal blocks 5, and a CAN box 6. The circuit breaker 2 is a safety device whose primary function is to disconnect or connect current in a circuit to prevent overload or short circuits. In this embodiment, a circuit breaker 2 is configured within the box 1 to control the power supply to all components within the box. The switching power supply 3 is a power conversion element that converts the input voltage, current, and power into the required output voltage, current, and power. In this embodiment, a switching power supply 3 is configured within the box to receive 220V AC power and convert it into 24V DC output power, which is used to power the wireless gateway and debugging interface. The wireless gateway 4, based on wireless network transmission technology, facilitates remote connection to the controller and CAN bus network within the vehicle's electrical system, enabling remote online monitoring and remote debugging. Terminal blocks 5 are electrical components used to connect circuits in electrical equipment, facilitating the connection and paralleling of wires. CAN box 6 is an electrical component used for monitoring and collecting CAN network data. It can be used to monitor the vehicle's CAN network data. One end of CAN box 6 connects to the bus terminal block, and the other end is used to connect to a PC.

[0031] like Figure 2 As shown, the debugging interface prefabricated on the surface of the box can facilitate the connection of components in the box to the vehicle electrical system, which is used to assist in debugging the vehicle or calibrating component parameters, thereby achieving the purpose of remote debugging the vehicle. The debugging interface of this embodiment includes but is not limited to a power interface 7, a serial port 8, two DEUTSCH connectors used for CAN bus interfaces 9, and two M12 connectors 10 used for external bus devices. Figure 3 As shown, the debugging operation box proposed in this embodiment is divided into two major parts: power supply and CAN network wiring. The power supply part is a 220V power supply introduced from the outside of the box, which is connected to the inlet of the switching power supply 3 through the circuit breaker 2. The outlet of the switching power supply 3 is connected to the power supply terminal, and then connected to the wireless gateway 4 and the power interface 7 of the debugging interface through the terminal. The CAN network wiring part refers to the connection of the interfaces of the wireless gateway CAN1 and CAN2 to the wiring terminals for the CAN bus, and then connected to the CAN interface of the debugging interface through the terminal, realizing the parallel connection of all CAN buses. In addition to the 220V AC and 24V DC power supplies mentioned above, the power supply of this embodiment can be connected to an external power supply or to the power supply of the vehicle.

[0032] The wireless gateway in the movable portable remote debugging operation box of this embodiment is connected to the vehicle controller through the serial port 8, so as to achieve the purpose of remote debugging the vehicle controller program, remote online monitoring, program modification, and remote debugging of the device. The vehicle CAN bus system is connected through the CAN bus interface 9 to achieve the purpose of remote monitoring of the vehicle CAN bus data, which is convenient for troubleshooting and cause analysis. The vehicle CAN bus devices, such as encoders, are connected through the M12 connector 10 to remotely calibrate the parameters of components such as encoders, which is convenient for external service personnel to perform parameter calibration and parameter modification when replacing equipment. The other end of the M12 connector 10 is used to connect to a PC.

[0033] In order to facilitate carrying and protect the components integrated in the box, a lock buckle 11 and a handle 12 are provided on the box body 1 in this embodiment.

[0034] The movable and portable remote debugging operation box proposed in this embodiment has a light appearance, a portable structure, and is equipped with a wireless gateway module, supports remote monitoring and operation, and improves maintenance convenience.

[0035] The use process of this embodiment includes:

[0036] When online monitoring of the vehicle's CAN bus data is required, external service personnel can connect the debug box to the vehicle's electrical system. First, connect the debug box's power interface to the vehicle's power system to power the debug box. Then, connect the debug box's CAN bus interface to the vehicle's CAN network to establish a CAN bus connection. Alternatively, a PC can be connected to the CAN box via a dedicated cable to monitor the vehicle's CAN bus data in real time. Alternatively, since the wireless gateway's CAN bus interface is also connected to the CAN network, technicians can remotely log in to the wireless gateway's backend to monitor the vehicle's CAN bus data.

[0037] When remote debugging is needed, external service personnel can connect the debug box to the vehicle's electrical system. First, connect the debug box's power connector to the vehicle's power system to power the debug box. Then, connect the debug box's serial port to the controller's serial port via a dedicated cable. The technician can then remotely log in to the wireless gateway backend and perform real-time online control, debugging, modification, and update of the vehicle program. To calibrate components such as encoders, external service personnel can connect the debug box to the vehicle's electrical system. First, connect the debug box's power connector to the vehicle's power system to power the debug box. Then, connect the debug box's CAN bus connector to the vehicle's CAN network to establish a CAN bus connection. The encoder and other components can then be connected to the debug box via an M12 connector. Alternatively, on-site personnel can connect a PC to the CAN box via a dedicated cable and perform parameter calibration on the PC. Alternatively, since the wireless gateway's CAN bus connector is also connected to the CAN network, technicians can remotely log in to the wireless gateway backend and perform parameter calibration directly on the encoder and other components.

[0038] Parameter calibration method: Taking the encoder as an example, send the protocol value to the fixed parameter calibration address of the encoder. For example, send 1234 to address 1 to realize the calibration of the encoder baud rate. For example, send 5678 to address 2 to realize the calibration of the encoder single-turn value. At the same time, after receiving the calibration data, the encoder will feedback a calibration success data. For example, after the baud rate calibration is successful, the encoder will feedback the value of 1111 to address 3, indicating that the calibration is successful. During the parameter calibration process, you can check the feedback value to determine whether the parameter calibration is successful.
