It is also connected on conducting wire between governor for solenoid；It is additionally provided on controller for oil relay；
It is also connected with actuator on the electron speed regulator, stopping working by actuator power-off makes diesel engine stop.
The automatic intelligent controller of the diesel generating set is to use 32 ARD single-chip microcontrollers, LCD liquid crystal display screen,
Chinese, English and the optional interface operation of other multilinguals, precision acquires diesel engine, each on generator, cooling water tank
Kind parameter, all parameters can be by standard setting and programming.
It is also connected on the controller and remotely starts switch K0, temperature measurement device SQ1, oil pressure measuring device SQ2, oil
Level measuring arrangement SQ3 and rotation-speed measuring device C1, D1.
The principle of the present invention is that the upper water chamber on the cooling water tank top of diesel engine installs low liquid level sensor；Secondly low
The passive normally-closed contact of liquid level sensor is connected to the programmable input port of diesel engine automatic intelligent controller, then uses PC machine
The program setting of low liquid level is carried out, time of fire alarming sets 8s, hard stop after alarm.
It is using the specific work process of technical solution of the present invention:
1) the switching value touching when the liquid level in cooling water tank is more than the installation site of low liquid level sensor, in low liquid level sensor
Point disconnects, and does not issue signal to diesel generating set automatic intelligent controller.
2) if the liquid level in cooling water tank is lower than the installation site of low liquid level sensor, opening in low liquid level sensor
Contact closure is measured in pass, issues signal, diesel generating set automatic intelligent control to diesel generating set automatic intelligent controller
After device processed receives signal, by process control, first issuing low liquid level sound-light alarm makes Fuel Injection Mechanism of Diesel Engine after 8S is delayed
K1 relay stops working, and disconnects the power supply of Digital Governor for Diesel Engine and Fuel Injection Mechanism of Diesel Engine solenoid valve immediately, holds diesel engine
The power-off of row device stops working, and diesel engine is shut down at once.
The beneficial effects of the invention are as follows；According to low liquid level sensor mounting height, to determine cooling water tank liquid level, when anti-
Freeze liquid or water is lower than the installation site of low liquid level sensor, low liquid level sensor exports on-off model, makes diesel-driven generator
The automatic intelligent controller of group receives signal, carries out logical operation immediately, issues alarm signal in advance, by certain time
After delay, make Diesel Engine Control power interruptions, it is ensured that the disorderly closedown of diesel engine.
