Embodiment
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.Following examples are used to explain the present invention, but are not restriction scopes of the present invention.
Vehicle-mounted fortune control equipment mainly acts on the advisory speed that provides train operation, and any safe condition of train is protected, and auxiliary driver drives.Under the point type; Vehicle-mounted fortune control equipment obtains the train position initial information through ground transponder; Obtain the train real-time speed through radar, speed pickup; Can calculate the range ability of train according to this speed, the advisory speed under the Query Database information acquisition current location guarantees that train moves below the speed of recommending.
When vehicle-mounted fortune control equipment is detected, require train to remain static, so speed pickup of train, radar, transponder etc. can't normally send, the function of vehicle-mounted fortune control equipment also just can not effectively be tested.The vehicle-mounted fortune control of the present invention equipment on-line testing appearance is simulated actual radar, transponder, speed pickup, replaces the interface of vehicle-mounted fortune control equipment and train, makes train under static situation, also can above-mentioned signal be provided to vehicle-mounted fortune control equipment.
As shown in Figure 1, vehicle-mounted fortune control equipment on-line testing appearance according to the invention comprises: guinea pig module 21 is used for sending radar signal to vehicle-mounted fortune control equipment; Analog answer device module 22 is used for to vehicle-mounted fortune control equipment transponder beacon information; Analog rate sensor assembly 22 is used for sending analog rate to vehicle-mounted fortune control equipment; Processing module 10 stores the database information on the vehicle operating circuit, and said database information comprises speed-limiting messages, the transponder information of each position; Processing module 10 is connected with analog rate sensor assembly 22 with said guinea pig module 21, analog answer device module 22 respectively, is used to control said guinea pig module 21, analog answer device module 22 and analog rate sensor assembly 22 and sends corresponding radar signal, transponder information and analog rate to vehicle-mounted fortune control equipment; And human-machine interface module 30, be connected with said processing module, be used to control size, the direction of the analog rate that tester produces.
Vehicle-mounted fortune control equipment on-line testing appearance simulation train runs to the process at B station from the A station; The inner integrated A of the tester database information on the B station track road of standing wherein comprises speed-limiting messages, the transponder putting position of each position and changes the transponder information etc. of position.
In the dry run process; Size, the direction of the speed that tester produces are controlled through the interface of human-machine interface module by the maintainer; The distance of operation is calculated by tester automatically, obtains current analog position, tester Query Database according to calculated distance; Obtain the transponder information under this position, send to vehicle-mounted fortune control equipment.
Vehicle-mounted fortune control equipment obtains the speed of current operation according to analog rate and radar signal that tester provides, according to this speed calculation range ability, also can from tester, obtain transponder information simultaneously, calculates current position.Vehicle-mounted fortune control equipment through calculate the position, judge that when arriving the B station carry out operations such as parkings, switch door accordingly, the maintainer can pass through the observation train status, judge whether vehicle-mounted fortune control equipment in proper working order.
Actual speed pickup can produce 2 the tunnel or the multichannel speed pulse signal, and the frequency of speed pulse signal is directly proportional with the train operation distance, and the phase relation that velocity pulse maintenance in several roads is certain is according to the direction of judging train operation of this phase place.In the present embodiment, the DF16 speed pickup that reaches electronics with Shanghai Germany and Italy is an example, sets forth the process of simulation.DF16 produces 2 road velocity pulses, and 2 road velocity pulses keep 90 degree or 270 degree phase relations, represent operation of train forward and inverted running respectively.
Vehicle-mounted fortune control equipment needs constantly the speed of speed pickup and the speed of radar to be compared, if error surpasses certain limit, will implement brake hard, so the analog rate sensor accuracy wants it very big.Bicycle-mounted portable formula tester is realized velocity pulse through FPGA, and FPGA has the pure hardware circuit characteristic, can not receive the influence of interruption, storehouse as single-chip microcomputer.FPGA can adapt to the speed pickup of multiple producer simultaneously, for the speed pickup that needs out of phase, different ways, only needs to revise the FPGA program and just can.
The clock of FPGA adopts 40M high precision crystal oscillator, counting unit of indoor design, and each clock count is once.When counting surpasses preset divide ratio, produce a velocity pulse.This frequency division will be presorted pulse frequently through d type flip flop and carry out 2 frequency divisions as presorting pulse frequently, form square-wave signal.Produce the rate signal of 2 tunnel phase phasic differences, 90 degree, the 1 road rate signal triggers at the 1st rising edge of square wave, the 2nd rising edge upset; The 2 road rate signal triggers at the 1st negative edge of square wave, and the 2nd negative edge upset produces synoptic diagram with reference to Fig. 2 velocity pulse.Can guarantee that like this 2 road velocity pulses keep 90 degree phase relations.When needs carry out inverted running, the output of 2 road velocity pulses transposing is got final product.
The clock of definition FPGA is M (40M), and presorting the frequency coefficient is P, and the velocity pulse size F that then produces is:
F＝M/(p*4)＝10000000/P
Divide ratio writes through processor, and least unit is 1, can calculate the error of velocity pulse:
ΔF＝10000000*(1/(P*(P+1)))
Divide ratio is more little, and the velocity pulse error is big more, and the pulsed frequency of speed is high more simultaneously.100 kilometers/hour velocity pulses that produce down of DF16 speed pickup approximately are about 3000HZ; Calculate minimum divide ratio according to this and should be 3333; At this in batches under the coefficient; The error amount of velocity pulse is 0.9, because the pulse of vehicle-mounted fortune control equipment picking rate can think that also through digital data acquisition FPGA can simulate the velocity pulse of the following optional frequency of 3000HZ.
The size of speed, direction need processor control FPGA to realize; The isa bus of FPGA mock standard; Different address is provided with velocity pulse divide ratio, velocity reversal, speed and register such as enables, and processor is realized the control to speed to the different address value of writing.
Actual transponder is made up of ground transponder and vehicle-mounted transponder two parts.During train process ground transponder, vehicle-mounted transponder sends to vehicle-mounted fortune control equipment through the information such as position of wireless acquisition ground transponder with this information.The transponder of thinking promise with the Shanghai Communications University is an example, through RS422 serial ports and vehicle-mounted fortune control devices communicating.In order to guarantee safety, reliable, onboard control device adopts 3 to get 2 platforms, and 3 main frames are arranged.Transponder also has 3 RS422 serial ports, respectively with 3 main-machine communications.
If bicycle-mounted portable formula tester is expanded 3 serial ports, not only increased on the cost a lot, and the real-time of 3 serial ports also is difficult to guarantee.Consider that what send under 3 transponder serial ports normal conditions is the same message, be extended to 3 serial ports on the serial ports Physical layer so utilize, referring to Fig. 3 transponder serial ports implementation, among the figure 1 tunnel serial ports expansion 4 road serial ports.
The RS422 level conversion adopts the max3088 chip of maxim to adopt realization, and max3088 is that TTL changes 485 chips, and every road 422 signal demands use 2 max3088, and a slice realizes sending, and a slice realizes receiving.
The serial ports transmit port is directly connected to " DI " pin of the max3088 of 4 tunnel transmissions, and the serial ports receiving port is directly connected to " RO " pin of the max3088 of 4 tunnel receptions.The transmission of 8 max3088, reception enable pin are controlled by processor.
Actual radar according to Doppler effect, calculates the travelling speed of current train, this speed is formed message send to vehicle-mounted fortune control equipment.The radar of main flow mainly is 422 or 485 communication interfaces, bicycle-mounted portable formula tester through wire jumper can be made into 422,485 two kind of interface.The radar that reaches electronics with Shanghai Germany and Italy is an example, and Physical layer adopts the RS485 level, and like Fig. 4 guinea pig 485 serial communications, every 15ms sends one group of message to vehicle-mounted fortune control equipment.
The bicycle-mounted portable formula provides one road serial ports to convert the RS485 level to.Because time requirement is relatively stricter, it is the highest that serial ports sends the priority location in the processor.
Bicycle-mounted portable formula tester needs miniaturization, makes things convenient for the user to carry, but has operation interface simultaneously, and man-machine interface is provided.Mostly product was to realize with the processor of the last operating system of needs such as PC104 module or ARM in the past.Bicycle-mounted portable formula tester core processor adopts single-chip microcomputer, communicates by letter signals such as control rate pulse with FPGA through data address bus; Man Machine Interface can adopt ripe Liquid Crystal Module, and the demonstration of Liquid Crystal Module, touch-screen control utilize microcontroller serial port to control.The advantage of bringing relatively like this is:
(1) with respect to using operating system, toggle speed is fast, is a millisecond rank basically;
(2) cost is low, and single-chip microcomputer and Liquid Crystal Module cost are all well below the PC104 module;
(3) response time fast, directly utilize the single-chip microcomputer timer regularly, can reach the microsecond rank;
(4) software programming is simple, need not carry out exploitations such as graphical interfaces processing.
In the dry run process, the maintainer can carry out fault and inject, and for example train exceeds the speed limit, stops to send radar message etc., and whether observe vehicle-mounted fortune control equipment can failure to the safe side.
Vehicle-mounted fortune control equipment on-line testing appearance can be simulated following fault in operational process:
(1) speed hypervelocity, the size of speed is provided with according to the advisory speed that shows on the tester by the maintainer, can artificially velocity simulate be surpassed advisory speed.
(2) speed pickup is invalid, and speed pickup is simulated by FPGA, the enabling and can be controlled by processor of every road velocity pulse.The maintainer can close certain road velocity pulse through the interface, perhaps the two-way velocity pulse is closed simultaneously.
(3) radar neutralization, radar neutralization has dual mode.A kind of is the speed deviations speed pickup speed that produces, and a kind of is not have the radar message.The input radar that tester can be thought departs from the ratio of speed pickup, perhaps directly closes the radar message.
(4) transponder lost efficacy, and can close the transponder message that sends to vehicle-mounted fortune control equipment main frame, the state of the carrying control equipment of also can analog answer device message dropping situation getting off.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and replacement, these improvement and replacement also should be regarded as protection scope of the present invention.
