Specifiions

Description
 
The main part of the excavator computer is the microprocessor and DSP, which is a circuit board that integrates a microcomputer unit (CPU), memory, and input and output interfaces. The microprocessor is the core component of the controller. The microprocessor converts the input analog signal into a digital signal, and compares and processes the stored reference data to calculate the output value. The output signal is amplified by power to control the actuator, such as a solenoid valve. and stepper motors. With the increasing computing power and memory capacity of single-chip microcomputer.
 

Characteristic
 
1. Reliable
2. Security
3. Durable
4. The excavator needs to travel in different working environments and climate conditions. The working environment of the excavator computer is poor, and it often needs to withstand vibration and changes in temperature and humidity. The power supply voltage of the excavator computer varies greatly, and it is also interfered by electromagnetic waves inside and outside the vehicle, so the excavator computer requires high reliability and durability to the environment. ​​
5. The excavator computer must be sufficiently intelligent, with self-diagnosis and detection capabilities, to be able to detect faults in the system in time, and to alarm and display fault codes to inform maintenance personnel where the fault may exist, so as to facilitate maintenance. For example, the oil pressure sensor must be turned on in a timely, correct and rapid manner at a critical moment, and the computer obtains the data to take action. However, most of the time, various sensors are on standby, so the excavator computer must have the ability to self-check, and constantly confirm whether the data of each sensor system is normal.
