In one embodiment, the sanding tube 210 is rated DN20-DN 32. The second tube segment 214 may be connected to the storage tank.
Referring to fig. 5, in one embodiment, the sanding assembly 200 further includes a sensor 220. The sensor 220 is connected to the control device. The sensor 220 is disposed on the sanding pipe 210, and is used for sensing whether sand exists in the sanding pipe 210 and the flowing state of sand. The sensor 220 is capable of sensing whether sand fluid is present in the sanding pipe 210. In one embodiment, the sensor 220 may employ a reddish light detection technique.
The sensor 220 may include a transmitting module and a receiving module of laser light, which are disposed at opposite sides of the sanding pipe. When the sand body passes through the sand spreading pipe, the reddish light emitted by the emitting module can be blocked or absorbed by the sand body, so that the amount of the reddish light received by the receiving module can be reduced. The amount of sand in the sanding pipe can be judged according to the amount of the micro red light received by the receiving module. In one embodiment, the emitting module may also emit light with certain transmittance, such as microwave or X-ray.
In one embodiment, the laser emitting module may be a reddish light emitting module. The reddish light may be microwave red light.
In one embodiment, the light received by the receiving module forms an image, the image is subjected to gray processing, and then the distribution of sand bodies in the sanding pipe is obtained according to the depth profile of the gray image. For example, the gray scale of a sand-containing position is deep, and the gray scale of an air-containing position is shallow. Namely, the sand amount of different positions in the sanding pipe can be judged. And judging whether the sanding pipe works normally or not according to the distribution of the sand bodies. In one embodiment, the sensor 220 may also predict whether there is a tendency for a blockage in the sanding pipe. And when the sand in the sand spreading pipe is distributed in a way that the upstream sand amount is larger than the downstream sand amount, and the downstream sand amount increment volume is less than 20% in the images with more than 10 continuous frames (the duration time can be 10 seconds), judging that the sand spreading pipe is blocked.
In one embodiment, the sensor 220 may be a gas-sand mixture flow sensor 220 (CX-18 SS 01). It will be appreciated that in the sandpipe, due to the small amount of sand, the small volume, the poor environment, and the fact that the sand is non-conductive, there is not a continuous full flow. Therefore, the detection difficulty is higher. The gas-sand mixed flow sensor 220 monitors the gas-sand mixed flow through research and analysis of the photoelectric technology. In addition, the gas-sand mixed flow sensor 220 is sensitive, accurate and strong in adaptability, and has electromagnetic and atomic radiation interference resistance; fine diameter, soft quality, light weight and mechanical performance; insulating, non-inductive electrical performance; water resistance and high and low temperature resistance; the locomotive can be installed in a narrow space at the bottom of the locomotive, the circuit connection is simple and easy, the locomotive is not influenced in severe weather with high and low temperatures, the locomotive is not influenced by electromagnetic interference and at the same time, the locomotive is hardly influenced in a dark and lightless place in a pipeline, and the sensitivity is high; the geometric shape has multi-aspect adaptability, and the shape can be changed according to the field; the material is used for high-voltage, electrical noise, high-temperature and corrosive severe environments; more important has explosion-proof characteristic, and factor of safety is high.
In addition, because the sanding is discontinuous, the amount of sand is small, and the sand irregularly passes through the sanding pipe 210, in order to monitor the accuracy and effectiveness of data, modeling and simulation can be carried out on the sanding solenoid valve by utilizing the AMESim technology, and the accuracy of the detection signal is compared, operated and processed by utilizing program operation.
In one embodiment, the sensor 220 utilizes a voltage conversion signal acquisition technology to convert the direct current 110V of the solenoid valve into an input signal of the control device for analysis and processing of the logical relationship of the sanding state. In one embodiment, the control device may be a unitary machine.
In one embodiment, the control device may have an input device. The input device may have a touch function to enable a touch action of a finger and any opaque objects. The input device can set system functions and download data.
In one embodiment, the sensor 220 includes a housing 210. The housing 210 has a recessed structure 211 that fits into the sanding tube 210. The housing 210 is sleeved on the outer wall of the sanding pipe 210 through the concave structure 211. Therefore, the sensor 220 can detect the sand and the flow of the sand in one circle of the sanding pipe 210 more completely. The detection is more accurate.
In one embodiment, the sensor 220 is disposed on the first pipe segment 212. The sensor 220 is disposed on the first pipe section 212 closest to the outlet of the sand, so that the detection accuracy can be effectively improved. The sensor 220 is more responsive.
In one embodiment, the control device may be a human-computer interactive all-in-one machine. The man-machine interaction all-in-one machine has the performances of explosion prevention, water prevention, dust prevention, electromagnetic interference resistance and the like. The input device has the advantages of good display effect, high brightness and contrast, high image definition and the like, and can carry out various interactive operations. The working principle of the device is that an optical signal monitored by the air-sand mixed flow sensor 220 is converted into a signal which can be recognized by the man-machine interaction all-in-one machine through a photoelectric signal, namely the detection signal. Then the detection signal is internally analyzed and processed, and the monitored signal is converted into a dynamic picture which is visually perceived by people. The dynamic picture can display the dynamic effect of sanding, and crew members can directly see whether the yarn tube is normal, blocked or free of sand.
In one embodiment, when the control device receives a braking or accelerating signal sent by the running control system and a sanding pedal is stepped down to control sanding, the control device receives a detection signal representing that sanding is normal, and then outputs a sanding normal signal; when normal signals are output, the human-computer interaction all-in-one machine can display a green indicator light and display 'normal'. The sensor 220 may output the detection signal. When the control device receives a braking or acceleration signal from the travel control system, the sensor 220 may be activated and ready to detect sand in the sanding pipe 210.
It can be understood that when the control device receives a braking or accelerating signal sent by the running control system and sanding is needed, a crew member can step on the sanding pedal at the same time, so that the sanding pedal is stepped on, and the sanding assembly sands.
When the control device receives a braking or accelerating signal sent by the driving control system and the sanding pedal is stepped to control sanding, the control device receives a detection signal representing sanding abnormity and outputs a sanding abnormity signal. When the sensor 220 does not detect sanding of the sanding pipe 210 in this case, a detection signal representing a sanding abnormality may be output. At the moment, the man-machine interaction all-in-one machine can display a red indicator light and display 'no sand' and prompt a fault.
When the control device does not receive a braking or accelerating signal sent by the driving control system and the sanding pedal is not stepped down to control sanding, the detection device receives a detection signal representing that a sand body exists in the sanding assembly 200 and outputs a blocking signal. That is, when the driving control system issues any driving command, the sanding pipe 210 always has sand therein. Sand is illustrated blocking the sanding pipe 210. The control means may thus output the blocking signal. At the moment, the man-machine interaction all-in-one machine can display a yellow indicator light and display a 'blockage' son. The fault automatically disappears if the blockage disappears.
When the control device does not receive a braking or accelerating signal sent by the running control system within a preset time and the sanding assembly 200 does not detect that the sand flows or remains, a standby signal is output. A standby signal is output. The control device may be maintained in a standby state at this time.
In one embodiment, the control device further comprises a real-time monitoring device, and the real-time monitoring device is connected with the control device. The real-time detection device is used for receiving the working state of the sanding component in real time.
Through railway locomotive sanding monitoring system can provide the management convenient for locomotive transportation management department.

In one embodiment, the sanding device comprises a temperature sensor 220 and a blowing assembly which are arranged on the sanding assembly 200, and the temperature sensor 220 and the blowing assembly are respectively connected with the control device. When the detecting device outputs a blocking signal, and the temperature detected by the temperature sensor 220 is lower than a preset temperature. To indicate that the sand block may be frozen and blocked due to too low temperature, the control device controls the air blowing assembly to blow air into the sand blowing pipe 210 in the sand blowing assembly 200 to blow away the blocked sand.
In one embodiment, the railroad locomotive 10 further includes a second wheel set 120, the second wheel set 120 being spaced in a same direction as the first wheel set 120. The second wheel set 120 is provided with the sanding assembly 200 on a side facing the first end 101 and a side facing the second end 102, respectively. It will be appreciated that the location and configuration of the sanding assembly 200 in the second wheel set 120 is the same as the location and configuration of the sanding assembly in the first wheel set 120. And will not be described in detail herein.
