Big device is metal-oxide-semiconductor.
The stucco control system host includes master controller, supply convertor, control button, display screen, host housing
For metal material, host externally draws other modules in cable connecting system, and it is shielded cable externally to draw cable.
The speed signal acquisition module connects master controller by transmitting the interface of digital pulse signal.
Pressure sanding control circuit is additionally provided in the stucco control system, forces the empty control of sanding control circuit connection electricity
Valve.
The application method and basic principle of the utility model be：
The device includes normal operating conditions and simulation two kinds of situations of working condition.
In normal operation, device acquires the brake signal of locomotive in real time.When locomotive speed is more than 15 km/h,
Locomotive emergency sanding control device attonity is closed control stucco electric pneumatic valve current supply circuit, maintains the original stucco control of locomotive；When
When locomotive speed is less than 15 km/h, intelligent logical controller output at this time controls signal all the way.The control signal through overdriving,
Phototube Coupling, switching tube driving, and then make relay coil energized action, cut-out control stucco electric pneumatic valve current supply circuit, so as to
Forbid stucco, ensure locomotive operation safety.
In the case where simulating working condition, the analogue-key on device is pressed, and current state is shown in display portion.This
When, driver moves the handle of emergency braking, and stucco part starts stucco（It can not certainly spread, the electricity for only starting stucco is empty
Valve）, device collects the brake signal of locomotive, display portion show current state and current speed for 60 kilometers/it is small
When（Wheel does not need to rotate）, subsequent speed slowly reduces, and real-time display, after speed is less than 15 kilometers/hour, device
Signal control stucco electric pneumatic valve current supply circuit is sent out, control stops stucco.After the brake signal of locomotive is invalid, device restores former
The state come, and restore to control stucco electric pneumatic valve current supply circuit original state.
The major function of the device is as follows：
1）Detection emergency brake signal in real time, after emergency brake signal is effective, device starts normal operating conditions.
2）Locomotive starts stucco during emergency braking, and after speed is less than 15 kilometers/hour, device control stops stucco.
3）Device can obtain locomotive speed signal in real time after detecting that stucco starts.
4）When locomotive approach section is repaiied, one-key start simulation stucco can simulate stucco control process.
Display portion can be with contents such as the current working state of system of real-time display, velocity informations.
The stucco input signal of locomotive emergency braking stucco control device is taken from stucco electric pneumatic valve front end, and speed signal takes
From in locomotive light electricity velocity sensor.The signal that the device collects locomotive speed sensor using difference channel in real time gives intelligence
Energy logic controller, the locomotive actual motion speed and speed that intelligent logical controller is fed back according to signal deteching circuit
Setting value compares to control the actuating of relay.When locomotive speed is when less than 15km/h, locomotive is forbidden sanding.In this way one
Determine to reduce husky discharge capacity in degree, not only reduce the maintenance cost at station but also the passenger for seating locomotive eliminates
Security risk, so as to improve the safety index of locomotive normal operation.In addition consider that the device is add-on assemble, so device
This does not influence sand sprayer work with certain self diagnosis repair function, while during failure of apparatus.That is, when device breaks down
And can not replace in time, still manually controllable stucco does not influence locomotive operation.
The device can check relay working condition in operation, on the one hand can automatically switch to normal condition operation；Separately
On the one hand, also to pass through the current working state of device of liquid crystal display.
