The invention discloses a communication method of an automobile instrument bottom plate and a core plate and relates to the technical field of automobile instrument communication. The invention aims to solve the problem of poor communication accuracy of an existing bottom plate and an existing core plate. The method comprises the steps that a bottom plate sequentially sends a start sign, a communication data ID, a communication data length and a communication data type to a core plate; the core board receives the start sign, the communication data ID, the communication data length and the communication data type, analyzes the communication data type, judges whether the communication data type is an event triggering type or a state time-varying type or not, and feeds back the analyzed communication data type to the bottom board if the communication data type is the event triggering type or the state time-varying type; the base plate judges whether the type of the sent communication datais consistent with the type of the fed-back communication data or not, if yes, the type of the communication data is sent successfully, then the base plate sends the communication data to the core plate, and communication between the base plate and the core plate is achieved. The method is suitable for realizing reliable communication between the bottom plate and the core plate.

    汽车仪表底板和核心板的通信方法,涉及车辆仪表通信技术领域。本发明是为了解决现有底板和核心板的通信准确性差的问题。本发明底板依次向核心板发送开始标志、通信数据ID、通信数据长度和通信数据类型;核心板接收开始标志、通信数据ID、通信数据长度和通信数据类型,并对通信数据类型进行解析,判断通信数据类型是否为事件触发型或状态时变型,是则核心板将解析后的通信数据类型反馈给底板,底板判断其发送的通信数据类型和反馈的通信数据类型是否一致,是则通信数据类型发送成功,然后底板向核心板发送通信数据,实现底板和核心板的通信。本发明适用于底板和核心板之间实现可靠的通信。
