The invention provides a CBTC dynamic data judgment queuing apparatus. The CBTC dynamic data judgment queuing apparatus comprises a judgment queuing apparatus, a time state collection circuit, a system speed curve mode generation apparatus, a communication port, a train tractive force collection apparatus, a train resistance collection apparatus and a train brake force collection apparatus. An air resistance collection apparatus collects air resistance and current resistance. The train brake force collection apparatus collects electric brake force. The train tractive force collection apparatus applies work by adopting common power in general. The train tractive force collection apparatus, the train resistance collection apparatus and the train brake force collection apparatus send collected data to the system speed curve mode generation apparatus through the communication port. The system speed curve mode generation apparatus needs to perform time integration with the time state collection circuit so as to perform regular operation of Cartesian product.

Through the CBTC dynamic data judgment queuing apparatus, the reliability of train operation is improved and the safety of train operation is effectively guaranteed.
Description
Technical field
The present invention relates to railway control field, particularly relate to the field that dynamic data in a kind of CBTC differentiates queue up automatic process and man-machine interactive operation.
Background technology
Train Detection and Identification (CommunicationBasedTrainControl, CBTC) based on communication is the new technology in China's track traffic signal field, and in CBTC, dynamic data differentiates that the major function of line-up device prevents train operation from exceeding the speed limit.The change of any object speed is all determined by the external force acted on the object, and equally, the velocity variations of train is also caused by the power acted on ON TRAINS.The main tractive force of train of external force suffered by train, train resistance and braking force of train in CBTC, the tractive force of train is produced by linear electric motors, and its size is determined by the rated power of motor and train running speed; Train resistance mainly contains electric current resistance, air resistance, additional drag, pantagraph current collector frictional resistance etc., they be train stressed in the most complicated; Braking force of train has electric braking force, mechanical braking force and Emergency Negative Thrust three kinds, be people is add to make it slow down ON TRAINS or power out of service.When one or more in three kinds of external force act on ON TRAINS simultaneously, the travelling speed of train will be changed, but how to consider this three kinds of power in CBTC, thus the maximum speed limit at the actual motion speed of train and objects ahead place is compared judgement, actual motion speed is reached and limits the situation of velocity amplitude and send warnings, excise tractive force or braking, do not reach maximum speed limit and within speed tolerance.
According to above problem, the present invention is compared to traditional approach in the past, and route table generates more succinct and accurately, generates with consumption of natural resource when calling less, start and the response time almost nil, therefore, the present invention has more advantage in the generation of route table.
Summary of the invention
The technical problem to be solved in the present invention is: the speed how acting force of train being changed to train by the size and Orientation changing power, makes it can accelerate to improve movement capacity, guarantees of also slowing down, thus the problem of raising train traffic safety.
For solving the problem, the invention provides following technical scheme:
Comprise differentiation line-up device, time state Acquisition Circuit, system speed curve model generating apparatus, communication port, train traction force acquisition device, train resistance harvester, train braking force acquisition device;
Air resistance collected by air resistance harvester, electric current resistance, train braking force acquisition device gathers electric braking force, train traction force acquisition device generally adopts conventional electric power to do work, train traction force acquisition device, train resistance harvester and train braking force acquisition device issue system speed curve model generating apparatus the data collected by communication port, system speed curve model generating apparatus needs and time state Acquisition Circuit are carried out a time and are amassed the regular computing carrying out cartesian product, the computing of dynamic data difference queuing policy is carried out finally by differentiation line-up device.
Accompanying drawing explanation
Fig. 1 is system assumption diagram of the present invention;
Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention will be described in detail.It should be noted that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention, the product that can realize said function belongs to equivalent to be replaced and improves, and is all included within protection scope of the present invention.Concrete grammar is as follows:
Embodiment 1:
When actual design, in CBTC, dynamic data differentiates that line-up device includes differentiation line-up device, time state Acquisition Circuit, system speed curve model generating apparatus, communication port, train traction force acquisition device, train resistance harvester, train braking force acquisition device; Wherein train traction force acquisition device, train resistance harvester, train braking force acquisition device is to collect three kinds of acting forces to train, wherein resistance can also comprise air resistance harvester collection air resistance according to actual conditions, electric current resistance, train braking force acquisition device gathers electric braking force, even can have gradient resistance, among namely gravitational resistance also can be considered.Train traction force acquisition device generally adopts conventional electric power to do work, or even steam engine pattern, train traction force acquisition device, train resistance harvester and train braking force acquisition device issue system speed curve model generating apparatus the data collected by communication port, the effect of system speed curve model generating apparatus carries out a time to amass with time state Acquisition Circuit the regular computing carrying out cartesian product, because acceleration needs to consider time relationship, and the one that the time is CBTC performance is considered, so timestamp judges in addition, the computing of dynamic data difference queuing policy is carried out finally by differentiation line-up device.
In the CBTC of the present invention's design, dynamic data differentiates that the advantage of line-up device mainly contains: run various effect to the acting force of train to carrying out different acceleration computings in CBTC according to reality, improve the reliability of train operation, effectively ensure the security of train operation.
