Slightly, using magnetoelectric transducer point type automatic level crossing signal control mode, to ironmaking North Road, center main road, steel-making North Road San Chu iron
Road level crossing carries out automatic alarm technological transformation, and protoplast's work guard road junction is changed into railway cross without watch.Road junction section alarm
Control uses non-insulated track circuit equipment, exists because light car moment " bounce " (i.e. driving phenomenon), and car team is taking road junction
Alarm-startup barrier machine rising stem phenomenon is interrupted during operation by sections in advance, especially No. three road junctions of railway are more prominent, have a strong impact on
The safe operation at road junction；In addition, road junction section audio non-insulated track circuit equipment, expensive, Frequent Troubles.
(1) automatic alarm system working procedure
Crossing automatic alarming system architecture, as shown in figure 1, when car team enters the magnetoelectric transducer top positive cutting magnetic of wheel rim
The steel magnetic line of force, sensor produces magnetoelectric induction signal, close to controller cut-out 24V controls power supply or injection circuit alarm area
Domain cut-out 24V control power supplys, host-initiated alarm；The excessively complete magnetoelectric transducer of car team leaves time delay after track circuit alarm region
Alarm 80~90s times；Car team keeps continuous alarm when taking road junction, car team by road junction after about 3 seconds, road junction naked rail
Road circuit sends out Pulse Width Control 24V and cancels voltage by YCGDK-1 types track transfer control box to main frame, and main frame automatically terminates report
It is alert.
(2) alarm phenomenon description is interrupted in advance
Peaceful steel railway signal automatic alarm road system, road junction section alarm uses non-insulated track circuit equipment, by closed circuit
Formula crossing controller control YCGDK-1 type track transfer control box realizes the lasting alarm of road junction section and releases alarm.Due to
The special climatic environment in seashore, rail easily corrosion, so as to cause track circuit shunting badness, car team wheel is to can not effectively short circuit
Rail voltage (signal), makes car team that moment " driving " phenomenon to occur when road junction operation by sections is taken, i.e. crossing equipment thinks car
Row have been moved off road junction, and the control YCGDK-1 type tracks transfer control of moment closed type crossing controller occurs in " driving " phenomenon
Box sends releasing alarm signal immediately, makes Host Interrupt intersection alarm-startup barrier machine rising stem.
Railway automatic alarm crossing equipment, either using magnetoelectric transducer point type automatic level crossing signal control mode, also
It is track circuit continous way control mode.Road junction section controlling alarm is domestic generally to use 480 track circuits or audio naked
Track circuit, but all exist because track circuit shunting badness, car team wheel to can not effectively short circuit rail voltage (signal), make car
There is moment " driving " phenomenon when being listed in occupancy road junction operation by sections, it is impossible to solve the problems, such as to interrupt alarm in advance, because track is electric
The interruption alarm problem that road shunting badness causes, not yet finds effective solution so far；In addition, road junction section audio is without exhausted
Edge track circuit equipment, expensive, Frequent Troubles, maintenance difficulty is big.

Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiments of the present invention are related to a kind of alarm control method for road junction section, using including detection circuit and
Control the device of circuit.As shown in Fig. 2 the detection circuit includes the magnet steel (SJ1 or XJ1) and track relay that are connected with each other
DGJ.As shown in figure 3, the control circuit includes alarm host machine and anti-track relay FDGJ, the track relay DGJ's
One path of contact composition is connected by the first diode D1 with the continuous alarm power end of the alarm host machine, the track
First normally opened contact and the alarm master of another path of the contact composition of relay DGJ by anti-track relay FDGJ
The releasing warning end of machine is connected；Described anti-track relay FDGJ one end is connected to the contact composition of the track relay DGJ
The first path and the first diode D1 between, other end connection field power supply KF；The anti-track relay FDGJ two
End is parallel with RC circuits；Second normally opened contact of the anti-track relay FDGJ is by the second diode D2 and the alarm master
The continuous alarm power end of machine is connected.
Workflow is described as follows：
A, continuous alarm and releasing warning circuit work
Car team starts close to magnet steel (SJ1 or XJ1) alarms, and car team takes road junction DGJ sections, makes relay DGJ losss of excitation, one
Aspect connects holding continuous alarm power supply, its circuit with contact 13 by the contact 11 of track relay DGJ：Power supply KZ → track
Relay DGJ11-13 → diode D1 → continuous alarm end 16, exports continuous alarm power supply, i.e. road junction section occupancy is protected all the time
Hold alarm；Another side connects the field power supply KF of its anti-track relay FDGJ, makes anti-track relay FDGJ actions adhesive, together
When give RC circuits charge, for release correspondence alarm point start alarm it is ready.Its circuit：Power supply KZ → track relay
DGJ11-13 → anti-track relay FDGJ → field power supply KF, charging energy-storing circuit：Power supply KZ → track relay DGJ11-
13 → resistance R → electric capacity C → field power supply KF；When car team goes out clear DGJ sections, encouraged immediately using track relay DGJ
Slow put moment (3s) of magnetic and anti-track relay FDGJ sends out pulse voltage, releases the alarm that correspondence magnet steel starts, open road
Mouthful, its circuit：Power supply KZ → track relay DGJ11-12 → anti-track relay FDGJ11-12 (slow to put 3s) → release alarm
A cancellation voltage is sent out to alarm host machine in end 1.
As can be seen here, the instant excitations of track relay DGJ and anti-track relay FDGJ when the present invention goes out clear using car team
It is slow put characteristic, a 24v pulse signal for cancellation intersection alarm is made to release main frame alarm, road junction is substituted without exhausted with this
Edge track circuit sends out Pulse Width Control 24V and cancels voltage function by YCGDK-1 types track transfer control box to main frame.
B, prevent " driving " operation principle
In the light car bounce of road junction section, when there is moment " driving " phenomenon, track relay DGJ excitations pick up cut-out to car team
Continuous alarm circuit, anti-track relay FDGJ keeps excited state (3s times) to continue to link up continuous alarm by accumulator
Circuit, the power supply KZ → main frame continuous alarm power supply of anti-track relay FDGJ21-22 → diode D2 → continuous alarm end 16.Really
Guarantor continuously keeps alarm at car team moment " bounce ".
It is seen that, the present invention cancels audio non-insulated track circuit equipment, changes and is performed by the track circuit of road junction section
Alarm is kept, continuous alarm is kept using the slow characteristic of putting of anti-track relay FDGJ, thoroughly solved because light car moment " jumps
It is dynamic " (i.e. driving phenomenon), the problems such as car team interrupts alarm-startup barrier machine rising stem in advance when road junction operation by sections is taken.
