Kind is by main controller controls, and another kind is carried out below to the principle of both control methods detailed by controlling from controller
It illustrates.
Mode one: it when the control main body is the master controller, is calculated by the phase detector described to be painted
The nozzle parameter of cylinder is penetrated, and it is as follows according to the nozzle parameter to control the concrete principle that the cylinder to be sprayed is sprayed:
Master controller needs to enter power-up state first, i.e., powers on to master controller；
After the completion of powering on, phase-triggered interrupt signal in the host controller, so that master controller is passed by the phase
Sensor calculates the nozzle parameter of the cylinder to be sprayed；
After the completion of calculating, including but not limited to by the execution chip of nozzle parameter write-in master controller, core is executed
Piece drives the execution moment of cylinder to be sprayed according to nozzle parameter judgement, and cylinder to be sprayed is driven to carry out work when reaching and executing the moment
Make.

It penetrates the nozzle parameter of cylinder, and the nozzle parameter is sent to described from controller；It is described to join from controller according to the injection
It is as follows that number controls the concrete principle that the cylinder to be sprayed is sprayed:
Into power-up state, and make simultaneously it is described enter power-up state from controller, and start simultaneously at timing；That is, described
Master controller and it is described carry out power-up state simultaneously from controller, and start simultaneously at timing.
After the completion of being both powered up when master controller and from controller, phase-triggered interrupt signal in the host controller, so that main
Controller calculates nozzle parameter and the first delay jet time of the cylinder to be sprayed by the phase detector；
After the completion of calculating, by the nozzle parameter, the first delay jet time and presently described master controller
Main timing time is sent to described from controller by CAN communication；
When receiving the nozzle parameter, the first delay jet time and the main timing time from controller,
CAN communication is interrupted at once, and records the presently described slave timing time from controller；
From controller according to the main timing time, described from timing time and the first delay jet time, calculate
Second delay jet time；
From controller according to the nozzle parameter, after waiting the second delay jet time, control described to be painted
Cylinder is penetrated to be sprayed.
Specifically, the master controller and the data communication between controller include but are not limited to CAN communication,
It is only illustrated by way of example in embodiments of the present invention.
Further, for according to the main timing time, described from timing time and the first delay jet time,
The described from controller of the second delay jet time is calculated, is specifically used for:
The main timing time is subtracted from timing time by described, obtains the third delay jet time；Third delay spray
Penetrate the data transmission period that the time is CAN communication；
The first delay jet time is subtracted into the third delay jet time, when obtaining second delay jet
Between.
Further, it is also used to judge whether the data transmission period of CAN communication is effective from controller, if the data are transmitted
Time is more than after preset time range, then it is assumed that CAN communication is abnormal, needs to carry out warning note to it, to repair place
Reason.
