In engine alerting system

for the complex and variation of connection form between controller and bottom sensors / actuators

it is difficult to identify fault positions

installation and maintenance of this system are also difficult and high cost. Aiming at these problems

an engine alerting system based on AS-i bus is designed.The system is constituted of power supply

an AS-i master and several AS-i slaves. Two AS-i cables are applied for power supply and data transmission. By software

the performance of the system is tested. The result of test shows that

communication of this system is reliable and its installation and maintenance is easy

low cost

which is beneficial to connection standardization of bottom device.
