    • A communication interface conversion device is suitable for electrically connecting a detecting unit and a vehicle electronic control unit (ECU) with different communication interfaces. The communication interface conversion device includes a first circuitry, a second circuitry, and a conversion module. The conversion module has a first transceiver unit, a second transceiver unit, an oscillation circuit, a resetting circuit, and a chip unit electrically connected with the first transceiver unit, the second transceiver unit, the oscillation circuit, and the resetting circuit. The first and second transceivers and the chip unit are used to perform data conversion, so that a first signal of the ECU and a second signal of the detecting unit which are of different communication interfaces can be transmitted, thereby improving generality thereof.
    • 通信接口转换装置适用于将具有不同通信接口的检测单元和车辆电子控制单元(ECU)电连接。 通信接口转换装置包括第一电路,第二电路和转换模块。 转换模块具有与第一收发器单元,第二收发器单元,振荡电路和复位电路电连接的第一收发器单元,第二收发器单元,振荡电路,复位电路和芯片单元。 第一和第二收发器和芯片单元用于执行数据转换,从而可以发送ECU的第一信号和不同通信接口的检测单元的第二信号,从而提高其一般性。

    • A hand-held diagnosis device (1) has a circuit module (11) having a micro-controller unit (111) and a diagnosing unit (112). The micro-controller unit (111) has an MCU-firmware update program and adapted to connect to a personal computer having a firmware-updating program via a communication port (13) to allow the personal computer (2) to update corresponding firmware for the micro-controller unit (111) to fit for different vehicles. The diagnosing unit (112) is connected to the micro-controller unit (111) and a cable (14) and diagnoses state of a vehicle via the cable (14) when the cable (14) connects to an electronic control unit (ECU) of the vehicle. Therefore the diagnosis device (1) can diagnose a vehicle of any brand without an outer computer and directly use electric power of the vehicle as its working power to avoid power failure.
    • 手持式诊断装置(1)具有电路模块(11),具有微型控制器单元(111)和诊断单元(112)。 微控制器单元(111)具有MCU固件更新程序,并且适于经由通信端口(13)连接到具有固件更新程序的个人计算机,以允许个人计算机(2)更新对应的固件 微型控制器单元(111),适用于不同的车辆。 当电缆(14)连接到电子控制单元(ECU)时,诊断单元(112)连接到微控制器单元(111)和电缆(14),并通过电缆(14)诊断车辆的状态, 的车辆。 因此,诊断装置(1)可以在没有外部计算机的情况下诊断任何品牌的车辆,并且直接使用车辆的电力作为其工作电力以避免停电。
