Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, the technical solution in the embodiment of the present application is carried out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall in the protection scope of this application.
Referring to Fig. 1, Fig. 1 is a kind of detection method of regeneration fuel oil valve misconnection provided in an embodiment of the present invention, the detection
Method is applied to the regenerating control device of grain catcher, and the regenerating control device of the grain catcher includes the first fuel oil
Valve, the second fuel valve, the first temperature and pressure transmitter and second pressure sensor, specifically, the detection method includes step
Suddenly：
S11, control first fuel valve are opened, and second fuel valve is controlled to close.
S12, the first pressure value for obtaining presently described first temperature and pressure transmitter and the second pressure sensor
Second pressure value；
In general, according to the trend of fuel oil, the structure of the regenerating control device of grain catcher is followed successively by shut-off valve, the first temperature
Pressure sensor, injection valve and second pressure sensor are spent, and the specific installation site of this structure is before equipment manufacture
Just set, and since the installation site of shut-off valve and injection valve is nearer, and the shape of the two is similar, therefore, often
Meeting wrong causes the power of regeneration of the regenerating control device of grain catcher to break down.
Based on this, inventor considers engine under normal activation state, and when shut-off valve is closed, the first temperature, pressure passes
The pressure of sensor and second pressure sensor is 0, and when shut-off valve is opened, injection valve is closed, the first temperature, pressure passes
The pressure of sensor is 5bar~8bar, and the pressure of second pressure sensor is 0bar.
Therefore, under the premise of uncertain two fuel valves are specifically shut-off valve or injection valve, wherein one is controlled first
A valve is opened, the shutdown of another valve.It is then detected that current first temperature and pressure transmitter and second pressure sensor
Current pressure values, and it is determined as first pressure value and second pressure value successively.
S13, judge whether the first pressure value and the second pressure value meet preset condition, when the described first pressure
When force value and the second pressure value meet the first preset condition, it is determined that the first fuel valve is shut-off valve, really described the
Two fuel valves are injection valve；
S14, when the first pressure value and the second pressure value meet the second preset condition, determine described first
Fuel valve is injection valve, and it is shut-off valve to determine second fuel valve；
Wherein, the first preset condition includes：First pressure value belongs to 5bar~8bar, and second pressure value is 0bar or the
Two pressure values belong to 5bar~8bar, and first pressure value is 0bar.Second preset condition includes：First pressure value and the second pressure
Force value is 0bar.
Schematically, when the first pressure value detected is 5bar~8bar, and second pressure value is 0bar, it is determined that with
The corresponding valve of first temperature and pressure transmitter is the first fuel valve, and it is second to determine valve corresponding with second pressure sensor
Fuel valve.
For another example, when the first pressure value detected is 0bar, and second pressure value is also 0bar, it is determined that with the first temperature
The corresponding valve of pressure sensor is the second fuel valve, and it is the first fuel valve to determine valve corresponding with second pressure sensor.
Whether the testing result of S15, the first fuel valve of comparison and the second fuel valve are identical with preset valve attribute, such as
Fruit is no, then alarms.
It in general, can be with preset shut-off valve and injection valve and the first temperature and pressure transmitter and second pressure in processor
The correspondence of sensor, e.g., the first temperature and pressure transmitter are arranged on the downstream of shut-off valve, therefore give tacit consent to the first temperature, pressure
The pressure value that sensor detects is the pressure value of shut-off valve, and second pressure sensor is arranged on the downstream of injection valve, therefore,
The pressure value that acquiescence second pressure sensor detects is the pressure value of injection valve.
And by above-mentioned steps, the pressure of current first temperature and pressure transmitter and second pressure sensor can be measured
Force value, then according to currently measuring as a result, incidence relation built in above-mentioned processor is compared, if it is different, then determining
Wiring error occurs for shut-off valve and injection valve, then alarms at this time.
For example, it is assumed that first pressure and the second pressure that the first temperature and pressure transmitter and second pressure sensor measure
Power is zero, then at this point, determine valve corresponding with the first temperature and pressure transmitter be the second fuel valve (injection valve), determine and
The corresponding valve of second pressure sensor is the first fuel valve (shut-off valve).And recorded in processor with the first temperature, pressure
The corresponding fuel valve of sensor is shut-off valve, and fuel valve corresponding with second pressure sensor is injection valve, therefore, is detected
As a result it is different with pre-recorded result, therefore, judge that with injection valve wiring error occurs for shut-off valve, send out alarm.
On the basis of above-described embodiment, the detection method of regeneration fuel oil valve misconnection provided in this embodiment, determining
The first fuel valve is stated as injection valve, determines second fuel valve after shut-off valve, also to have carried out further judgement, such as Fig. 2
It is shown, including step：
S21, control first fuel valve are closed, and second fuel valve is controlled to open；
S22, the third pressure value for obtaining presently described first temperature and pressure transmitter and the second pressure sensor
The 4th pressure value；
S23, judge whether the third pressure value and the 4th pressure value meet first preset condition, if
It is to determine first fuel valve as injection valve, it is shut-off valve to determine second fuel valve.
In above-described embodiment, when the first pressure value detected is 0bar, and second pressure value is also 0bar, it is determined that with
The corresponding valve of first temperature and pressure transmitter is injection valve, and it is shut-off valve to determine valve corresponding with second pressure sensor.
On this basis, inventor can will appear pressure sensing it is considered that when fuel valve cannot be opened if a failure occurs
The pressure value detected on device is 0 situation, and in order to exclude this case, the present embodiment further controls the second fuel valve to open
It opens, the first fuel valve of control is closed, and then reacquires working as the first temperature and pressure transmitter and second pressure sensor again
Preceding pressure value is defined as third pressure value and the 4th pressure value successively.When third pressure value be 5bar~8bar, the 4th pressure
When being worth for 0bar, it is determined that valve corresponding with the first temperature and pressure transmitter is shut-off valve, is determined and second pressure sensor
Corresponding valve is injection valve.
It should be noted that the detection method of regeneration fuel oil valve misconnection provided in this embodiment, as shown in figure 3, can be with
Before pressure value detection is carried out, including step S31：The shut-off valve, injection valve, described is first determined whether by processor
Whether the first temperature and pressure transmitter and the second pressure sensor break down, if so, sending out fault alarm information.
The fault detect is the units test of engine in itself, is not described in detail herein.
