Be again started up after 30 seconds, total boot time is no more than 80 seconds, and total number of starts is no more than 3 times, if it is continuous three times it is inactive at
Function, then system report startup separator.The shutdown control of engine generates a driving signal by single-chip microcontroller, controls flame-out oil cut-off valve,
The fuel supply for cutting off engine when flame-out oil cut-off valve is connected, while judging that the generator on engine body exports
Voltage shows engine stop at this time after the generator output voltage on engine body drops to the voltage value of setting
Machine, after delay about 3 seconds, single-chip microcontroller generates a control signal, closes flame-out oil cut-off valve, completes to shut down control.
The Engine ECU control module of generating set is connected by CAN communication circuit with the CAN interface of single-chip microcontroller, single
The CAN of piece machine works in listening mode, and at work, ECU module acquires the operation information of engine to engine in real time, such as turns
Speed, water temperature, the parameters such as engine oil pressure send single-chip microcontroller by CAN network interface.Single-chip microcontroller receives Engine ECU module biography
The CAN message information brought, and parsed, the operation information of shipping machine is obtained, and module is led to by 4G the whole network and is passed in real time
Remote server is given, maintenance personnel can check real time information by Terminal Server Client platform or cell phone application software.
In order to realize the local control nearby of generator remote control system, in this programme by a personal-machine interface circuit with
The input terminal of single-chip microcontroller is connected, and man-machine interface circuit is local control circuit；Local control circuit includes keyboard input electricity
Road and information display unit are, it can be achieved that operating parameter input setting, parameter modification, information inspection, the functions such as setting information preservation.
By man-machine interface (local control circuit) can be achieved it is local to the engine start of generating set, flame-out control, operating parameter,
Alarm parameters setting, emm message prompt, real time temperature, voltage, electric current, power is shown, Service Phone is arranged, and network parameter is set
The functions such as set.As the support system of local man-machine interface, realize that generator remote control system further comprises a memory
Unit realizes the record storage to above- mentioned information.With realize information record in real time, the storage of fault message, operation data leads
The functions such as out.
Information exchange between generator remote control system and remote web server leads to module by a 4G the whole network
