ECU controller of excavator

ECU (Electronic Control Unit) electronic control unit, also known as "travel computer", "vehicle computer" and so on. It is the same as an ordinary computer, consisting of a microprocessor (MCU), memory (ROM, RAM), input/output interface (I/O), analog-to-digital converter (A/D), and large-scale integrated circuits such as shaping and driving. composition. The voltage working range of ECU is generally 6.5-16V (there is a voltage stabilizing device in key internal parts), the working current is 0.015-0.1A, and the working temperature is -40℃~80℃. It can withstand vibrations below 1000 Hz, so the probability of ECU damage is very small. In the ECU, the CPU is the core part, which has the function of calculation and control. When the engine is running, it collects the signals from the sensors, performs calculations, and performs calculations. The result is transformed into a control signal to control the work of the controlled object. It also controls the memory (ROM/FLASH/E…
