It is not used in restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, people in the art
The present invention can be made various changes or modifications by member, and these equivalent form of values fall within the application appended claims equally and limited
Scope.
Embodiments of the present invention relate to a kind of alarm control method for road junction section, use and include testing circuit and control
The device of circuit.As in figure 2 it is shown, the interconnective magnet steel of described testing circuit (SJ1 or XJ1) and track relay DGJ.
As it is shown on figure 3, described control circuit includes alarm host machine and anti-track relay FDGJ, described track relay DGJ's
One path of contact composition is connected with the continuous alarm power end of described alarm host machine by the first diode D1, described rail
Another path of the contact composition of road relay DGJ is by first normally opened contact of anti-track relay FDGJ and described report
The releasing warning end of alert main frame is connected；Described anti-track relay FDGJ one end is connected to touching of described track relay DGJ
Between first path and the described first diode D1 of some composition, the other end connects field power supply KF；Described anti-track relay
Device FDGJ two ends are parallel with RC circuit；Second normally opened contact of described anti-track relay FDGJ passes through the second diode
D2 is connected with the continuous alarm power end of described alarm host machine.
Workflow is described as follows:
A, continuous alarm and releasing warning circuit work
Car team starts close to magnet steel (SJ1 or XJ1) reports to the police, and car team takies road junction DGJ section, makes relay DGJ loss of excitation,
On the one hand holding continuous alarm power supply, its circuit: power supply are connected with contact 13 by the contact 11 of track relay DGJ
KZ → track relay DGJ11-13 → diode D1 → continuous alarm end 16, exports continuous alarm power supply, i.e. road junction section
Take and remain warning；Another side connects the field power supply KF of its anti-track relay FDGJ, makes anti-track relay
FDGJ action adhesive, charges to RC circuit simultaneously, ready for releasing the warning of corresponding alarm point startup.Its circuit:
Power supply KZ → track relay DGJ11-13 → anti-track relay FDGJ → field power supply KF, charging energy-storing circuit: electricity
Source KZ → track relay DGJ11-13 → resistance R → electric capacity C → field power supply KF；Clear DGJ section is gone out at car team
Time, utilize slow put moment (3s) of the instant excitation of track relay DGJ and anti-track relay FDGJ to send pulse electricity
Pressure, releases the warning that corresponding magnet steel starts, open road junction, its circuit: power supply KZ → track relay DGJ11-12 → anti-
Track relay FDGJ11-12 (delay and put 3s) → releasing warning end 1 is sent one to alarm host machine and is cancelled voltage.
As can be seen here, the instant excitation of track relay DGJ and anti-track relay FDGJ when the present invention utilizes car team to go out clear
Delay and put characteristic, make a 24v pulse signal cancelling intersection alarm, release main frame and report to the police, substitute road junction without absolutely with this
Edge track circuit controls box by YCGDK-1 type track transfer and sends Pulse Width Control 24V cancellation voltage function to main frame.
B, prevent " driving " operation principle
Car team is beated at the light car of road junction section, and when there is moment " driving " phenomenon, track relay DGJ excitation picks up cut-out
Continuous alarm circuit, anti-track relay FDGJ keeps excited state (3s time) to continue to link up continuously by accumulator
Warning circuit, power supply KZ → anti-track relay FDGJ21-22 → diode D2 → continuous alarm end 16 main frame is reported continuously
Alert power supply.Guarantee to keep continuously when car team moment " beats " reporting to the police.
It is seen that, the present invention cancels audio frequency non-insulated track circuit equipment, changes and is performed holding by the track circuit of road junction section
Report to the police, utilize the slow characteristic of putting of anti-track relay FDGJ to keep continuous alarm, thoroughly solve because light car moment " beats "
(i.e. driving phenomenon), car team interrupts the problems such as startup barrier machine rising stem of reporting to the police in advance when taking road junction operation by sections.
