It needs to establish numerous monitoring stations along trunk railway, but there is detection dead zone, can not achieve detection on locomotive；Train fortune can not be detected
During row, train unbalance loading phenomenon caused by due to bend, speed change, inclination etc. is super to Heavy-haul Freight train, inclined
Detection in real time is carried to have a very important significance.
Invention content
The object of the present invention is to provide a kind of vehicle-mounted weighing methods measuring goods train based on bolster, overcome traditional title
Disadvantages mentioned above existing for heavy equipment has many advantages, such as that high efficiency, high-precision, maintenance easy to install, low cost, function are easily expanded, complete
The real-time detection of the full super leaning load for being suitable for goods train.
The technical scheme is that：A kind of vehicle-mounted weighing method being measured goods train based on bolster, this method are passed through
In bogie bolster upper surface installs vehicle-mounted weighing sensor additional, is generated for perceiving bolster surface because car body weight changes
Strain value, and strain value is converted into corresponding voltage or AD signals.Vehicle intelligent terminal is installed in car bottom, for adopting in real time
Collect and handle each sensing data, accurate weight is obtained eventually by calibration.
Vehicle intelligent terminal is by ARM embedded controllers unit, power supply unit, positioning unit, wireless data sending unit, number
The weighing unit and high reliability that I/O interface units, weighing-up wave amplification are constituted with modulate circuit with analog to digital conversion circuit are supervised
Data storage cell is controlled to constitute.
The present invention is by the bolster upper surface designated position installation sensor special in goods train bogie, then passes through weight
Code or known weight object demarcate system, ultimately form goods train vehicle-mounted weighing system.This method overcomes traditional goods
Fortune train fixed point weigh and operational process present in problems, have real-time Super leaning load monitoring, sound state combine, precision
Height is applicable in the advantages that vehicle is extensive, at low cost.
Description of the drawings
Fig. 1 is bogie structure schematic diagram.
Fig. 2 is the vehicle-mounted weighing sensor schematic view of the mounting position of goods train.
Fig. 3 is system composition schematic diagram.
Fig. 4 is system calibrating process schematic.
Specific implementation mode
The content of present invention is described in detail below in conjunction with attached drawing and example.
It will be seen from figure 1 that goods train weight transmitting sequence after topping-up, compartment is seated at bogie center bearing 3
On, cartridge 3 transmits the force to bolster 4, and bolster 4 transmits the force to side frame 2 by spring 5, and side frame 2 is again by bearing 1 by power
Wheel shaft 6 is passed to, is finally acted on rail 7.Wherein bolster 4 is used as independent load component, and exhaustive power is possible, therefore
Vehicle-mounted weigh can be realized by measuring bolster deformation information indirectly.
By modeling simulation analysis, among bolster spider and side bearing the output of upper surface location stress it is larger and linearly compared with
It is good, therefore 11 installation site of vehicle-mounted weighing sensor is as indicated with 2.
One section freight compartment needs 4-8 Special vehicle-mounted weighing sensor altogether, wherein the bolster both sides of a set of bogie are each
1-2 is installed only.Four groups of vehicle-mounted weighing sensors independently upload weight information, are combined by four vehicle-mounted weighing sensor data,
It can obtain single-unit gross train weight amount, trailing or leading bogie unbalance loading situation and each bogie or so unbalance loading situation.
Vehicle-mounted weighing sensor when mounted, take microbeam weld, be bonded, being screwed etc. modes can, installation side
Just, it will not cause to impact train safely, have the characteristics that low cost, convenient installation.
As shown in 2, Fig. 3, below 1) vehicle-mounted weighing sensor installation process is described in detail to vehicle-mounted weighing and sensing
Device installation site (cartridge and side bearing centre position bolster upper surface) is determined and sanding and polishing；
2) vehicle-mounted weighing sensor state is installed in determination；
3) in the vehicle-mounted weighing sensor 4-8 of bolster selected location installation, only (single set bogie installation 2-4 is only vehicle-mounted as required
Weighing sensor, the fixed forms such as bonding, welding, bolt) each sensor is using independent (sensor number=port number, example
Such as：4 sensors are installed, point 4 port numbers) or grouping (sensor number>Port number, such as：8 sensors of installation, every 2
One group, points of 4 channels acquisitions) form is summarized in the intelligent instruments in vehicles 8 of body bottom installation by cable, and final port number is
C (C=1~4)；
4) vehicle-mounted title intelligence instrument 8 and power module 9 are installed in body bottom centre position, if vehicle body is self-powered, lead to
It crosses the power module and converts voltages into voltage value needed for instrument, if vehicle body does not have power supply, the power module is directly to instrument
Energy supply；
5) 11 subchannel of vehicle-mounted weighing sensor is accessed by instrument by shielded cable 10；
6) determine that 11 access state of vehicle-mounted weighing sensor, fixed each component complete system installation；
7) determine that data transmission is normal, data can complete transmission by number of ways such as 4G, bluetooths and realize vehicle by calibration
Carry function of weighing.
