Example 2

Identifying the locomotive and prompting to drive a scotch block: through two infrared sensor that shelter from, adopt the logical mode of establishing ties to discerning through the locomotive, install both ends around two layers of operation platform respectively. When the front and rear infrared sensors simultaneously recognize the shielding signals, it is indicated that a locomotive passes through, when the front and rear infrared sensors simultaneously recognize the shielding signals for more than 5 seconds (the delay time is debugged according to the actual situation on site), it is determined that the locomotive is in a stable state, and at this time, a voice prompt can be performed on a driver or an inspection driver, as shown in fig. 5; such as: and 3, finishing the locomotive, and calling the wheel stopper (prompting for 2 times) and simultaneously displaying a green character of the wheel stopper calling on the LED display screen. When only one is masked for more than 5 seconds as shown in FIG. 6, it is also determined that the locomotive is already in a parked state.

Confirm and indicate that the scotch block has been beaten, the mode of action: two infrared sensors and two proximity sensors are employed. The two infrared sensors are respectively arranged on the two scotch block bases and adopt a serial logic mode. The initial state is a normally closed state, and the two scotch block are in a disconnected state after being respectively separated from the base; a proximity sensor: two proximity sensors are respectively installed on the upper end surfaces of the wheel stoppers (the installation is ensured not to influence the action effect and the construction performance of the wheel stoppers). A serial logic approach is used. The proximity sensor on the wheel stopper is in a normally open state, and the proximity switch is closed after the wheel stopper is well opened. The action principle of the proximity sensor is as follows: and when the distance is smaller than a set value by detecting the vertical distance between the tread and the upper surface of the wheel stopper, the switch is closed.

How to judge that the iron shoe is well-finished:

according to the requirements of the administrative rule of the vehicle driving in the Tianjin locomotive service section: the locomotive and the vehicle staying in the section are prevented from sliding uniformly, and the sliding prevention of the iron shoe is realized. When the iron shoe is used for preventing slipping, the toe cap is tightly attached to the wheel tread and firmly fixed. Due to the difference in wheel size between the HX and DF type locomotives, the vertical distance from the tread to the skate will also vary. Therefore, the DF type locomotive with smaller wheel diameter is adopted to carry out parameter acquisition. After two scotch block were beaten simultaneously, can carry out voice prompt to the driver: "the X-track locomotive has finished the scotch block" (voice prompt 2 times) and the "red typeface" that "the scotch block has finished" is displayed on the LED screen.

And (3) the return prompt of the wheel stopper:

after the servicing operation is finished, after the two wheel stoppers are completely removed, the two proximity sensors are disconnected, and after the two wheel stoppers are completely swung and reset, the two infrared sensors are closed; the driver is subjected to voice prompt that the wheel stopper of the X-channel locomotive is removed (the voice prompt is carried out for 2 times), and meanwhile, the red character of the 'typed wheel stopper' displayed on the screen is changed into the green character of the 'removed wheel stopper'; at the moment, the locomotive can be released, and after the locomotive moves forwards out of the range of the two locomotive identification infrared shielding sensors, the LED screen is turned off.

Prompting of the motor vehicle with the wheel stopper:

two proximity sensors are arranged on the upper end face of the wheel stopper, the sensors are in a normally open parallel logic relationship, the triggering sensing distance is 6mm, when the proximity switches of the iron shoes on the wheels roll to act, an alarm is given to a driver, the voice prompt is 'warning, please remove the wheel stopper of the X-channel locomotive', and a red flashing character of 'please remove the wheel stopper' is displayed on an LED screen.

And (3) prompting by a wheel pulling and stopping device in continuous hanging operation:

the two infrared shielding sensors on two sides of the recognition servicing locomotive are respectively additionally provided with one infrared shielding sensor, the recognition is close to the shunting machine of the servicing locomotive, the two sensors adopt a parallel logic mode, and when any one of the two sensors is shielded, voice prompt is carried out: the method comprises the steps of 'connecting operation, requesting to remove the wheel stopper before the motor car', and displaying 'the wheel stopper is not removed' on an LED screen.
