and S30, if the judgment is overtime, outputting an alarm prompt to the human-computer interface.
In the embodiment, the invention provides a method for outputting an alarm prompt to a human-computer interface by judging the spice sending time and the alarm preset time, in order to solve the problem that after the spice sending liquid is used for a long time, a spice discharging pipeline and a feeding gear pump are likely to be blocked due to the residual spice liquid, so that feeding is abnormal. The specific implementation operation is shown in fig. 5:
taking an L13 tank for feeding to an on-site LA7 tank as an example, when an LA7 tank sends a material requiring signal, if the L13 tank can meet the requirements of a material requiring brand and a material requiring amount of the LA7 tank, a material outlet valve of the L13 tank can be opened and a gear pump is started for feeding, and when the L13 tank detects that the material dispensing weight reaches the material requiring amount of the LA7 tank, the material outlet valve and the gear pump are closed, a compressed air valve is opened, and the material liquid in a material outlet pipeline is blown into the LA7 tank. If the material sending time is too long or too short relative to the preset alarming time, the invention outputs an alarming prompt to a human-computer interface and starts the procedures of checking, cleaning or replacing the discharging pipeline and the gear pump.
Preferably, the method for determining the alarm preset time in S20 is as follows:
s201, collecting spice dispensing historical record data, and storing the spice dispensing historical record data in a database, wherein the spice dispensing historical record data comprises dispensing weight and dispensing time corresponding to the dispensing weight;

s204, setting a deviation time difference for the determined real-time material sending time to generate an alarm time zone;
s205, determining that the time in the alarm time zone is alarm preset time.
In the embodiment, the characteristic relation between the material dispensing weight and the material dispensing time is obtained by analyzing the historical data of the perfume material dispensing, the real-time material dispensing time is determined according to the characteristic relation, the deviation time difference is set for reducing the false alarm rate of the alarm, the alarm time zone is generated, and the time in the range of the zone is determined as the alarm preset time.
Preferably, the characteristic relationship between the hair weight and the hair time is a linear characteristic relationship.
Preferably, the relation of the linear characteristic relation is as follows: y is 1.87X-1.494.
Preferably, the absolute value of the deviation moveout is the difference between the current calculation of the perfume burst time and the previous calculation.
Preferably, the material weight is the weight of the material liquid in the tank before material dispensing and the weight of the material liquid in the tank before material dispensing.
Preferably, the perfume dispensing time is calculated as the operating time of the feed gear pump.
In this example, referring to fig. 6, the present invention extracts and analyzes the perfume dispensing history records from the database, and finds that the dispensing weight (kg) and the dispensing time(s) are approximately linear, taking the example of feeding L13/L14 to LA7/LA8 on site, the perfume dispensing time is calculated once per second, 2080 records are collected, and curve fitting is performed on the dispensing weight (X/kg) and the dispensing time (Y/s), so as to obtain:
Y＝1.87×X-1.494，
if the deviation is +/-30 s, the number of abnormal samples is 2 (0.10%), 1.87 XX-1.494-30, Y is more than 1.87 XX-1.494 +30, the abnormal samples are normal,
as shown in table one:
watch 1
The data fit results are as follows:
Linear model Poly1:
f(x)＝p1×x+p2
Coefficients(with 95％confidence bounds):
p1＝1.87(1.863,1.878)
p2＝-1.494(-2.425,-0.5624)
Goodness of fit:
SSE:6.308e+004
R-square:0.9912
Adjusted R-square:0.9912
RMSE:5.51
when Y is less than 1.87 XX-1.494-30, the hair-dressing time is too short:
when Y is more than 1.87 xX-1.494 +30, the hair-feeding time is too long:
x: hair weight (kg), Y: hair material time(s)
Programming a program code to circularly calculate whether the material sending time exceeds the specified time every second, and if the material sending time exceeds the specified time, carrying out alarm prompt on a human-computer interface. Historically, when the deviation range is set to be ± 30s, the probability of false alarm is very low. Therefore, when the system frequently gives an alarm of 'long material sending time', the alarm can be used as an early warning for abnormal conditions such as blockage of a pipeline and a gear pump, and the pipeline and the gear pump can be inspected, cleaned or replaced to avoid complete blockage and influence on production; when the system frequently gives an alarm of 'too short material sending time', the system can be used as an early warning for abnormal weight detection of the material liquid in the tank.
