如何用python实现对tbox的doip诊断测试

在Python中实现TBox DOIP诊断测试，你可以使用第三方库，如`pyobd`或者`can-utils`（如果你的TBox支持CAN总线），它们提供了一套方便的接口来与车辆进行通信。以下是一个简单的示例流程：

# 安装所需库 (如果有未安装，运行pip install pyobd can-utils)
import pyobd

# 连接至车辆
connection = pyobd.OBD()
connection.query('ATI')  # 检查连接是否成功，'ATI' 获取车辆基本信息

def doip_read_did(did):
    response = connection.query(hex(did))  # 根据DID值读取数据
    if response.is_valid():
        return response.value
    else:
        print(f"Invalid response for DID {hex(did)}")

def doip_write_did(did, value):
    command = f'{hex(did):02x}={value}'  # 构造写入命令
    try:
        response = connection.send_command(command)
        if response.is_valid():
            print(f"Wrote {value} to DID {hex(did)}")
        else:
            print("Write failed")
    except pyobd.exceptions.RequestError as e:
        print(f"Write error: {e}")

# 测试DIagnosis DIDs 和 DTCs
did_values_to_test = [0x01, 0x02]  # 替换为你想要读写的DID列表
for did in did_values_to_test:
    read_value = doip_read_did(did)
    print(f"Read: {read_value}")

# 清除DTC
clear_dtc_request = '0xd0'
connection.send_command(clear_dtc_request)

# 结束连接
connection.close()
