Description
Technical field
The invention belongs to the technology category of subway wheel counting apparatus；Particularly relate to base oneself upon existing subway wheel counting apparatus, using laser-correlation
The highly reliable multi-functional wheel counting apparatus system and method for instrument.
Background technology
Cut-off in December, 2012, Hangzhou bus trip share rate go fromes bad to worse depressing：2000, routine bus system was average
Speed per hour 15.3km, share rate 22.2% of going on a journey；2011, routine bus system average speed per hour 12.3km, trip share rate was down to the lowest point
20%.On 2 22nd, 2013, Hangzhou proposed to make public transport turn into the first-selection of citizens' activities, public affairs in 2021 with the time of 10 years or so
Hand over share rate quantitative target >=50%.For existing engineering technology and land resource, the leading role of bus trip share rate is improved
Non- subway does not belong to.Subway freight volume is big, take up an area less, quickly, it is convenient, on schedule, low energy consumption, ride comfort and safety.
1969, Chinese first subway was built up in Beijing；In May, 2013, China opens subway in 16 cities.2012 10
Month, the Hangzhou Subway Line 1 of total length 48km is runed, then 23.24 ten thousand person-times of the average daily volume of the flow of passengers；Using AC frequency conversion Type B car, four
Dynamic two drag, six marshallings, the people of staffing 1240, design F-Zero 80km/h, standard running interval 120s.2013, Hangzhou was public
Surrender the counteroffensive of row share rate and rise 3.20%, the declining trend for increasingly declining is reversed at one stroke.2013, subway transported citizen 8483.1 ten thousand
Person-time；2014,14450.4 ten thousand person-times；2015,17629.5 ten thousand person-times.On May 1st, 2015, create the odd-numbered day 125.33 ten thousand
Person-time passenger flow peak.Obviously, subway plays very important role in public trip share rate.The Asian Games in 2022 are called together
Before opening, the circuit of the whole city ten puts into operation, total kilometrage 192km coverings area of the whole city 9.The remote inferior high ferro of subway speed, but train interval is remote
Small high ferro, usual two cars interval time≤120s, or even 90s or shorter.
Based on track circuit traditional subway Train Detection and Identification (Track-circuit Based Train Control,
TBTC) taken by subway train operation control (Communication Based Train Control, CBTC) based on communication
Generation；High ferro Train Detection and Identification is similar with subway.In CBTC systems, checking the technology and equipment of track section free time/occupancy is
Ensure the core support technology and equipment of safe train operation；The standard for following is science and technology department of the Ministry of Railways, the issuing and implementation of electric business office
's《TB/T 2296-2011 railway signal axis-counting device generic specifications》.On July 23rd, 2011, Yongjia to Wenzhou section
D3115 rear end collision of motor train tragedies have punctured the bottom line of safe train operation, show improvement track section it is idle/take Examined effect and
The urgency of equipment, necessity；At present, the track section that obtains practical application is idle/take inspection equipment be track circuit and
Axis-counting device.
It is conductor that track circuit uses train axle, and train axle short circuit band electric rail produces train occupation track section
Signal.The operating mode of track circuit is closely bound up with the state of rail, and relying on rail can just make " idle/to take " judgement, pass
Defeated " idle/to take " signal；The loose contact once rail gets rusty or aoxidizes, the normal work of track circuit is often hard to carry on,
The humiture change of railway roadbed sleeper can also import the uncertainty of track circuit operating mode.Track circuit shunting badness and red band are stupid
The Ji Long phases perplex engineers and technicians and operation maintenance employee, by rail level polishing spraying, 3Vization or high-voltage pulse, multiple features rail
The remedial measures such as road circuit, though the inherent shortcoming of track circuit obtains alleviation to a certain degree, eliminate the root of its inherent shortcoming
All the time it is difficult to find trace in the road of sheet.One speech covers it, and track circuit is influenceed greatly by extraneous factor, and fault rate is high, poor reliability, gradually
By the rivers and lakes status of marginalisation, fame follows merit.
Axis-counting device and correlation technique are derived from the Europe of the forties in last century, German Lao Lunci General Electric Co. Limited AZL70
Type axis-counting device enjoys high reputation；Chengdu Railway communication equipment factory of domestic enterprise, batch release JZ.GD-1 type axis-counting devices.1985

Gas company AZS70 type axis-counting devices.Judge that " idle/to take " highlights the huge of axis-counting device with the independence of track, railway roadbed situation
The principle defect of big technical advantage, i.e. track circuit has not existed.Additionally, axis-counting device is also equipped with verifying integrity of train
Potential quality.Axis-counting device sets a wheel counting apparatus (point) at the entry/exit mouth of each track section, and wheel counting apparatus wheel detector is based on electromagnetism
Principle of induction, the detection train number of axle (wheel logarithm)；Section free time criterion：The number of axle of and if only if the into/out section is consistent；
Integrity of train criterion：The number of axle that and if only and if train automatic monitoring system (Automatic Train Supervision,
ATS) the axletree sum of related train is consistent.Wheel counting apparatus are by installing two groups of high frequency wheel detectors (magnetic head) in orbit, electricity
Sub- box (detector), and indoor set composition；Every group of high frequency wheel detector (magnetic head) includes one group of transmission/receiving coil.
During train approach wheel counting apparatus, wheel changes the electromagnetic signal of transmit coil transmitting；The electromagnetic signal of axletree information is included by receiving
Coil is received, and electronic box extracts axletree information, obtains the number of axle.Wheel counting apparatus based on electromagnetic induction principle are easily done by extraneous electromagnetism
Disturb, cause number of axle statistical error, reliability reduction；And the electromagnetic environment in subway place is complicated severe：As locomotive traction motor becomes
The stray field of depressor, subway large power-consuming equipment, the locomotive magnetization magnetizing part of rail brake, magnetic goods or by leading
Draw magnetic field that electric current is formed around rail etc..Must be pointed out second deficiency of wheel counting apparatus, wheel counting apparatus when train runs at a low speed
Performance indications be deteriorated；Because the electromagnetic signal of wheel counting apparatus collection through moving the modulation of wheel, and need to run at a low speed the tune of wheel
Intensity processed tends to become weak.For the deficiency of wheel counting apparatus, it is subway problem urgently to be resolved hurrily to develop multi-functional highly reliable axle counting system.Meter shaft
