Restore photoelectric sensor module (18) again to be connected with one-chip computer module (1) the level freedom of pin, is allowed to reenter monitoring
State.
Shown in Fig. 1, the present apparatus selects STC89C516RD single-chip microcontroller as control core, which may be implemented to interrupt
And the function abundant such as timing, serial communication, by realizing the work of various settings to the controllable I/O port of single-chip microcontroller write-in program,
Stability is good.Five line four phase step motor drive modules are selected as ULN2003A, and signal end pin connects single-chip I/O mouth, can be real
The positive and negative rotation control of this existing stepper motor is turned over to control positive and negative turn 90 degrees after objective table (13) reach above foreign matter collection platform
Turn, foreign matter is made to fall and return to horizontal position；Four line two-phase stepper motor drive modules are selected as L298N, pass through four line two-phases
The drive characteristic of the controllable X of the rotation of stepper motor, Y-axis linear transmission mechanism, signal end pin connect single-chip I/O mouth, are written
Function is rotated, it can be achieved that X-axis linear transmission mechanism drives photoelectric sensor straight along the foreign matter and Y-axis of X-axis scanning objective table (13)
Line drive mechanism control transmission bracket (11) makes objective table (13) leave and return track switch along Y-axis level；Wireless communication module (2)
Signal receiving end RXD and signal sending end TXD connects single-chip microcontroller TXD and RXD pin respectively, for realizing wireless communication, when there is report
When alert signal needs to issue or needs to receive train driving control signal, which can be achieved it；Hall sensing
Device module and magnetisable material (9) are separately mounted near safe baffle (22) side in place set by Y-axis linear transmission mechanism
In safety in place the transmission slide unit 1 (10) of baffle (22) other side, when Y-axis linear transmission mechanism band dynamic object stage (13) is along Y
When axis Linear transmission, the magnetisable material (9) and Hall sensor module being driven on slide unit 1 just have distance change, if transmission is slided
Platform 1 does not reach at safe baffle (22) in place, and Hall sensor module keeps high level signal constant, opposite Hall sensor
Module exports low level, and control or alarm can be realized according to this signal level.
Shown in Fig. 2, objective table (13) is placed in above turnout rail and main orbit, the rotation of five line four phase step motors (12)
Terminal connects objective table (13), and the rotation for controlling five line four phase step motors (12) just can control the rotation of objective table (13)；Control
Case (23) processed includes control circuit board (20) and its electric wiring as shown in Figure 1, is encapsulation state.
Fig. 2 show railway and track switch section rough schematic.Opening and closing between turnout rail and main orbit determines train
Driving direction, the opening and closing of turnout rail is driven by goat to be completed.If having in the gap between turnout rail and main orbit
Foreign matter exists, and goat driving turnout rail movement cannot be completed, and the electric signal of goat accumulation at this time is conveyed to manual control
Alarm is realized in room, requests artificial treatment.To realize that track switch is removed obstacles automation, theory of the invention is proposed.
Not limited to this, any change or replacement expected without creative work should all be covered in guarantor of the invention
Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
