The invention discloses a convenient-to-replace display instrument for an engineering vehicle. The convenient-to-replace display instrument comprises an instrument body, an external switch and a vehicle controller. By arranging a CPU signal processing module with a central control function in the instrument body, an instruction issued by a user can be effectively processed, and the instrument canbe used in cooperation with various controllers, so that the universality of the product is improved, and the cost of replacing the controllers by the user is reduced. The instruction issued by the user directly enters the instrument body and then enters the vehicle controller in a CAN communication mode, so that the signal processing mode is effectively optimized, the signal delay is reduced; compared with a traditional analog communication mode, the CAN communication reduces the number of wiring harnesses; later maintenance and replacement are facilitated, and meanwhile, due to the fact thatthe instrument can communicate with the vehicle controller, the vehicle controller state, the fault code and other information can be displayed; and the information display effect is effectively provided, the user investment cost is saved, and the defects in the prior art are effectively overcome.

    本发明公开了一种便于更换的工程车辆用显示仪表,包括仪表本体、外部开关以及车辆控制器;本发明通过在仪表本体内设有中枢控制功能的CPU信号处理模块可以有效的处理用户下达的指令,同时可以和各种控制器搭配使用,以增加了产品的通用性,且减少了用户更换控制器的成本,用户下达的指令直接进入仪表本体然后通过CAN通讯的方式进入车辆控制器,进而有效的优化了信号处理方式减少了信号延迟,相较于传统的模拟通信方式,CAN通信减少了线束的数量,方便后期的维修和更换,同时由于可以和车辆控制器通讯,所以可以显示车辆控制器状态和故障代码等信息进而有效的提供显示信息效果节约用户投入成本从而有效的弥补了现有技术中的不足。
