The locomotive is provided with an air pump, each air pump extends out of a plurality of sand blasting pipelines to be respectively connected with a plurality of sand spraying mechanisms 100, the distance from the air pump to each sand spraying mechanism 100 is different along with the change of the arrangement position of the sand spraying mechanisms 100 on the locomotive body, after a sand spraying instruction is triggered by a driver, the time for the air pump to transmit compressed gas to each sand spraying mechanism 100 is slightly different, along with the increase of the distance, the time delay is also increased, so that the actual sand spraying time of each sand outlet is not completely consistent;
measuring the length of the sanding line 140 to be S 0 The air speed of the air inlet of the sand spraying pipeline 140 is V 0 The air speed of the air outlet of the sand spraying pipeline 140 is V 1 Average velocity V in sanding line 140 Average of The time delay detection duration T corresponds to the wind speed V of the air outlet of the sand spraying pipeline 140 2 The delay module calculates a wind speed attenuation factor r= (V) according to the distance S between each sand spraying mechanism 100 and the corresponding air pump 1 -V 0 )/V 0 /S 0 Then, the air outlet speed V of the corresponding sand spraying pipeline 140 is calculated 2 =V 1 (1-rS) and according to the average velocity V in the sanding line 140 Average of =( V 2 +V 1 ) Calculating the time T=S/V of the delay monitoring Average of The delay module sends out delay monitoring signals according to the calculated delay time through the detection module and the corresponding monitoring device 150, so that the monitoring is realizedThe device 150 monitoring time corresponds to the sanding time of the sanding mechanism 100;
when a driver triggers a sanding instruction, each sand discharge valve 130 is opened, so that sand in the sand box 110 enters the sanding pipeline 140 through the sand discharge pipeline 120, temporary storage is carried out in the sanding pipeline 140 of the U-shaped sand in the sanding pipeline 140, and when compressed gas is released, the sand can be sprayed out of the U-shaped sanding pipeline 140, so that the possibility of self loss of the sand from the sanding pipeline 140 is reduced, the sand can be sprayed out more uniformly, the sanding effect is improved, and meanwhile, the loss of the compressed gas in the next sanding process is reduced;
by arranging the identifier 160, the corresponding distance between the sand box 110 and the air pump is correspondingly recorded, the identifier 160 transmits the position of the sand box 110 to the time delay module, and the time delay module judges the corresponding time delay monitoring time according to the signal of the identifier 160, so that the accuracy of the detection time is further improved; in the process of sprinkling out the equal sand through a sprinkling outlet in the sanding pipeline 140, the monitoring device 150 starts monitoring according to the delay signal before the sand passes through the signal transmitter 151 and the signal receiver 152, and when the air pump discharges the compressed gas into the sanding pipeline 140, the sand in the sanding pipeline 140 is pushed out by the compressed gas, and the sand is sprayed out of the sanding pipeline 140 to be sprinkled to a corresponding position; the monitoring module records and outputs the monitored sanding signals and sanding times, so that the possibility of failure in sanding action recording and inaccurate sanding times caused by different sanding times is reduced, the detection accuracy of the sanding mechanism 100 is improved, the possibility of inaccurate sanding information monitoring caused by different sanding times is reduced, a driver can more conveniently judge the sanding condition of each sanding opening, and the sanding problem of each sanding opening can be found in time and overhauled;
when the sand spraying time delay module starts to send monitoring signals to the monitoring module, the monitoring module sends out light through the control signal transmitter 151, the signal receiver 152 receives light signals sent by the signal transmitter 151, when sand segments pass through, the sand segments block the light in the sand spraying pipeline 140, the signal receiver 152 cannot receive the light signals of the signal transmitter 151, the signal receiver 152 judges that one sand spraying action is finished, the signal receiver 152 sends out signals to the monitoring module, the monitoring module records and outputs the signals, if the materials of the sand are different, the light intensity of the signal transmitter 151 can be adjusted according to requirements, if the sand density is larger, the light intensity of the signal transmitter 151 can be adjusted to be high, the influence of the tail end of the sand segments on light propagation is reduced, and then the monitoring effect is improved.
When the first sanding is finished, the sanding pipeline 140 is filled with compressed gas, and the compressed gas can rapidly react to a sanding position, so that time delay is not needed in the second sanding, and the time delay module sends a signal to the main control module according to the time delay, so that the main control module controls the sand discharge valve 130 to delay sand discharge, the possibility that the air pump drives the compressed gas into the sanding pipeline 140 while sand discharge is reduced, and sand discharge is orderly performed; when the sand outlet is abnormal in sand spraying, the judging module judges that if the sand outlet is in a condition of leaking, and the like, the judging module transmits a signal to the main control module, and the main control module determines the sand box 110 where the sand outlet with a problem is positioned according to the signal of the judging module, and controls the sand box 110 symmetrical to the sand outlet with the problem, so that the next sand spraying is stopped, the possibility of rolling caused by different adhesion coefficients of two sides of part of wheels when the locomotive is braked or accelerated is reduced, and the locomotive is enabled to run more stably;
if the signal receiver 152 firstly loses the light signal of the signal transmitter 151 when the sanding action starts, the monitoring module sends a signal to the time module, the time module starts timing, when the sand segments are completely scattered, the signal receiver 152 receives the signal of the signal transmitter 151 again, the monitoring module sends a signal to the time module again, meanwhile, the sanding action is recorded once, the time module transmits a time signal required for recording the completion of the sanding action to the judging module, the judging module judges the sanding time once, if the sanding time is less than the time required for normal sanding, the sand amount scattered by the sanding is indicated to be too small, the abnormal sanding is also included, the judging module transmits a signal with too small sanding amount to the output module, the output module records and outputs the signal, the monitoring range of the sanding mechanism 100 is improved, and a driver can respond to the abnormal problem in time; in the sanding process, the sensor 170 detects the sand content in the sand box 110 in real time, when the sand storage amount in the sand box 110 is reduced to a certain degree, the sensor 170 outputs real-time information of each sand box 110 through the output module, and a driver can timely find the condition of the sand box 110 and perform sand filling and the like.
The implementation principle of the locomotive sand spraying monitoring control system provided by the embodiment of the invention is as follows:
by arranging the sanding mechanism 100 and the control system on the locomotive, after a sanding instruction is triggered by a driver, each sand discharge valve 130 is opened, so that sand in the sand box 110 enters the sanding pipeline 140 through the sand discharge pipeline 120, temporary storage is carried out in the sanding pipeline 140 of the sand U-shaped in the sanding pipeline 140, and when compressed gas is released, the sand can be sprayed out of the sanding pipeline 140 of the U-shaped, so that the possibility of self-loss of the sand from the sanding pipeline 140 is reduced, the sand can be sprayed out more uniformly, the sanding effect is improved, and meanwhile, the loss of compressed gas in the next sanding process is reduced; the delay module judges the corresponding delay monitoring time according to the signals of the identifier 160, so that the accuracy of the detection time is further improved; in the process of sprinkling sand through the sprinkling outlet in the sanding pipeline 140, the monitoring device 150 starts monitoring according to the delay signal before the sand passes through the signal transmitter 151 and the signal receiver 152, when the air pump discharges compressed air into the sanding pipeline 140, the sand in the sanding pipeline 140 is pushed out by the compressed air, the sand is sprayed out of the sanding pipeline 140, and the sand is sprinkled to the corresponding position, so that the sanding result record is more accurate, the possibility of inaccurate sanding information monitoring caused by different sanding time is reduced, a driver can more conveniently judge the sanding condition of each sanding port, the sanding problem of each sanding port can be timely found, and overhaul is performed.
The above embodiments are not intended to limit the scope of the present invention, so: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
