The embodiment of the application also provides a railway locomotive. The railroad locomotive includes the railroad locomotive sanding assembly.

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, 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'.

When the air-sand mixture flow 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 running control system, the detection device receives a detection signal representing that sand bodies exist in the railway locomotive sanding assembly 200, and then a blocking signal is output. 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 railway locomotive sanding assembly 200 does not detect the flow or the retention of the sand, 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 system comprises a temperature sensor and a blowing assembly which are arranged on the sanding assembly 200 of the railway locomotive, and the temperature sensor and the blowing assembly are respectively connected with the control device. When the detection device outputs a blocking signal, and the temperature detected by the temperature sensor is lower than a preset temperature. To illustrate the potential for sand blockage due to freezing at too low a temperature, the control device controls the air-blowing assembly to blow air into the sanding pipe 210 in the railroad locomotive sanding assembly 200 to remove the blocked sand.
