Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
On the one hand, the present invention provides a kind of vehicle positioning device, as shown in figures 1 to 6, including housing 1, circuit board 2 and battery,
Circuit board 2 and battery are arranged in housing 1, and battery is connected with circuit board 2 and is powered circuit board 2, and circuit board 2 is arranged
Having ultra broadband module 21, ultra broadband module 21 connects antenna 4, and housing 1 scribbles Anti-static paint, and antenna 4 is sealed by marine glue
It is contained in antenna casing 41.
The vehicle positioning device of the present invention is used for being arranged on the Underground Mine locomotives such as colliery, it is achieved the communication to mine locomotive
The functions such as contact, locating and tracking and management and running.Present invention uses ultra broadband (UWB) technology to communicate, there is location
Precision high (positioning precision can be accurate to 30cm), signal cover wide (identifying that distance can reach 800m), transmission bandwidth high and
The advantages such as extensibility is good.Well solve the problem that mine locomotive location is difficult, by the track and localization of mine locomotive and
Real-time Communication for Power is dispatched, and efficiently avoid may produce in mine locomotive driving process and blocks the accident even collided.Improve
The efficiency of the safety in production of mine locomotive.
And scribble Anti-static paint on the vehicle positioning device shell of the present invention, eliminate electric spark, it is ensured that mine locomotive is in ore deposit
The safety of down-hole, antenna is encapsulated in antenna casing by marine glue, good water-proof effect.
In sum, the vehicle positioning device positioning precision of the present invention is high, signal cover is wide, transmission bandwidth is high, can expand
Malleability is good;And ensure that locomotive safety under mine, good water-proof effect.
According to country's regulation (GB3836.1-2010) to underground equipment, produce electric spark to reduce surface of shell
May, the surface insulation resistance of nonmetallic materials shell is not more than 109 Ω, and surface area is less than 10000mm2。
The shell material of the present invention is flame-proof ABS material, and its surface insulation resistance is not more than 109 Ω.Due to the present invention's
The surface area of circuit board is 15000-16000mm2, preferably 15876mm2 so that the surface area of housing is naturally larger than
10000mm2, it is therefore desirable on housing, scribble Anti-static paint, to eliminate electric spark.And antenna to be size smaller, surface area
For 2000-3000mm2, preferably 2500mm2, and Anti-static paint is very big on the impact of aerial signal, therefore antenna and shell thereof are not
Need to be coated with Anti-static paint.
Marine glue is preferably PU5562 glue, its good water-proof effect, and the signal of antenna will not be produced impact.Encapsulation side
Method is: put into by antenna in antenna casing, then according to 1:1 ratio, the AB component of PU5562 glue is carried out allotment and stirs evenly rear encapsulation
In shell, until antenna all submerges in glue, it is put into the high place of temperature and treats that it solidifies.
Therefore the present invention had both eliminated the electric spark on housing, improve safety, the signal of antenna will not be produced shadow again
Ring, and waterproof effect is more preferable.
As a kind of improvement of the vehicle positioning device of the present invention, battery is rechargeable battery, and housing 1 is provided with draw-in groove 11,
Battery is arranged in battery compartment 3, and is watered by epoxy resin envelope, and battery compartment 3 is detachably arranged in draw-in groove 11, and by not
De-screw is fixed.
Colliery regulation can not be charged in down-hole, and battery the most of the prior art is all non-charging battery, and service life is short.
The present invention uses rechargeable battery, and devises a mobile battery storehouse, at least one batteries is installed in battery compartment, uses ring
Epoxy resins carries out encapsulation, it is achieved waterproof.During installation, battery compartment is directly pushed in the draw-in groove of shell, then carry out with not taking off screw
Fixing.When changing battery, screw will not be taken off and turn on, and battery compartment be pulled out, then battery compartment can be taken outside mine
Charging.
Present invention achieves the chargeable of vehicle positioning device battery so that the life-span of battery increases, and battery waterproof effect
The best, firmly install, the dismounting of battery compartment, install convenient, simple, fast.
Charging for convenience, battery connects waterproof charging connector 31, but (i.e. vehicle positioning device is in down-hole in use
Time, namely non-charged state), need waterproof charging connector is carried out waterproofing protection, it is to avoid expose, can arrange on housing 1
The accommodating groove of waterproof charging connector 31 is received under non-charged state.The present invention further ensure that the waterproof effect of battery.
The water resistance of battery compartment needs to reach IP65, waterproof charging connector preferred S1210-7P aviation plug, this plug
Water resistance preferable.
Further, battery can be ferric phosphate lithium cell.
As the another kind of improvement of the vehicle positioning device of the present invention, circuit board 2 is provided with PA module 22 and inertial navigation module
23.Use PA module and inertial navigation module to achieve voltage detecting and motion state detection, and these information uploaded to host computer,
Realize monitoring in real time.
On the other hand, the present invention provides a kind of mine locomotive, including car body and above-mentioned vehicle positioning device, vehicle positioning device
It is fixed on car body by backboard 6 and column 7.
The mine locomotive positioning precision of the present invention is high, signal cover is wide, transmission bandwidth is high, extensibility is good, safety
Good, the good water-proof effect of property.
Backboard and from live mounting means have multiple, it is preferred that column 7 is fixed on car body, the one side of backboard 6 and column
7 connect, and another side is connected with housing 1 back side of vehicle positioning device by screw.
Its installation method is: first installs a metal upright post on the suitable position of car body, can use welding, tie up
The modes such as fixed, screw is fixing.Then the backboard with precautions against earthquakes that vehicle positioning device is unified is fixed on metal upright post
?.Fixation of the present invention, shockproof properties is good.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, it is also possible to make some improvements and modifications, these improvements and modifications are also
Should be regarded as protection scope of the present invention.
