Description

A kind of new-type antiskid device

Technical field:

The utility model belongs to the track traffic equipment technical field, relates to the anti-skid device that is applied to a kind of new structure under the railroad track vehicle occasion, the new-type antiskid device of using on particularly a kind of trolley coach.

Background technology:

At present; Fast development along with the track railway; Safety, control accuracy and stopping distance to vehicle operating are all had higher requirement; Existing rolling stock anti-skid device ubiquity the shortcoming of many structure imperfections, and exists preparation, shortcoming that the operation and maintenance cost is high, thus autonomous Design, production a kind of safe and reliable, cost is low, use and the anti-skid device system simply and easily of safeguarding has become and makes great efforts the technical assignment sought in the industry.

Summary of the invention:

The goal of the invention of the utility model is to overcome the shortcoming that prior art exists; Seek design a kind of new type passenger car anti-skid device system is provided, comprise a cover main frame, quadruplet speed sensor, quadruplet exhaust valve and a cover pressure relay, can when car brakeing, make full use of binding force to greatest extent; Obtain desirable stopping distance; And preventing the locking and the damage of vehicle runner to have failure self-diagnosis and information recording technique function, safe and reliable, control is accurately and the low characteristics of cost.

To achieve these goals, the agent structure of the utility model comprises anti-skid device main frame, speed sensor, exhaust valve and pressure relay; The anti-skid device host output end of box structure is through three groups of transmission cables of RS232 or the parallel connection output signal of RS485 generic interface difference; Parallel symmetrical structure is connecting four speed sensors on first group of transmission cable; Parallel symmetrical structure is connected with the exhaust valve of four same structures on second group of transmission cable, and the 3rd group of transmission cable communication type that powers on is connected with pressure relay; The anti-skid device main frame that adopts the microcomputer structure is communicated with formation integral structure anti-skid device with four speed sensors, four groups of exhaust valves and pressure relay electrical information respectively; Signal conditioning and information record and process software system are housed, the electrical information of real time recording and processing speed sensor, exhaust valve and pressure relay and realization output print or demonstration in the anti-skid device main frame.

The power supply voltage of the utility model is DC48V ± 30% or DC110V ± 30%; Adopt the exhaust valve of 24V normal voltage to be applicable to various application conditions; The fault data that main frame is stored under off-position is not lost, and shows on computer screen through service interface, or networks with chopping machine and display terminal, and the result is printed or sends out; Speed sensor is connected with the respective row air-valve, does not need extra instrument to differentiate out; The adaptation voltage range is 16.8-150VDC; Main frame adopts all outputs of microprocessor monitors; Four independent security monitor are as external security appliances; Used pressure relay contact can both be monitored from inside and outside; Adopt two-way output signal and six relay contacts so that fast recording and the reflection running velocity and the distance of going.

The utility model compared with prior art, its integral structure is simple, prepares easy for installationly, cost is low, safe reliability is good, long service life can be widely used in drag in the high-speed track train.

Description of drawings:

Fig. 1 is the connection structure principle schematic of the utility model.

The specific embodiment:

Below through embodiment and combine accompanying drawing to be described further.

Embodiment:

The agent structure of present embodiment comprises anti-skid device main frame 1, speed sensor 2, exhaust valve 3 and pressure relay 4; The mouth of the anti-skid device main frame 1 of box structure is through three groups of transmission cables of RS232 or the parallel connection output signal of RS485 generic interface difference; Parallel symmetrical structure is connecting four speed sensors 2 on first group of transmission cable; 3, the three groups of transmission cables of exhaust valve that parallel symmetrical structure is connected with four same structures and performance on second group of transmission cable communication type that powers on is connected with the pressure relay 4 of conventional structure; The anti-skid device main frame 1 that adopts the microcomputer structure is communicated with formation integral structure anti-skid device main body with four speed sensors 2, four groups of exhaust valves 3 and pressure relay 4 electrical information respectively; Signal conditioning and information record and process software system are housed, the electrical information of real time recording and processing speed sensor 2, exhaust valve 3 and pressure relay 4 and realization output print or demonstration in the anti-skid device main frame 1.

The anti-skid device main frame 1 that present embodiment relates to adopts microcomputer to control, and anti-skid device main frame 1 is contained in the metal box of a compact conformation, and the metal box has anti-preferably high-frequency performance, has anti-vibration and impact property; Four terminal fittings that are provided with through anti-skid device main frame 1 downside connect vehicle line, carry out maintenance, operation and the diagnosis of anti-skid device through the RS232/RS485 interface; The 1 control data collection of anti-skid device main frame and processing and internal control; All functions are all undertaken by microcontroller; Per 28 milliseconds are upgraded take off data, guarantee to use under the 2-400km/h speed, and the axle speed that anti-skid device main frame 1 will be measured compares with the speed of calculating based on actual axle speed; The comparison of two kinds of speed can judge whether runner gets into sliding state; When anti-skid device main frame 1 judges that vehicle is in sliding state, then control exhaust valve 3 actions, the air pressure in the brake cylinder is reduced, thereby runner is rotated further; Four speed sensors 2 are responded to the gear signal of four wheels respectively, and signal is sent to anti-skid device main frame 1, anti-skid device main frame 1 are arranged through obtaining the running velocity of train after calculating; Exhaust valve 3 links to each other with the brake pipe of locomotive; Be installed under the locomotive position near brake cylinder; The increase and decrease of exhaust valve 3 control brake in-cylinder pressures avoids sliding generation to guarantee the braking force that acquisition is best and to produce best braking effect, the exhaust valve 3 inner 24V voltages that adopt; The bipolar driving circuit, each positive and negative polar curve is equipped with amplifier; Guaranteeing safety, if misoperation takes place, then can cut off the electricity supply by the correct connection that supervisory circuit can monitoring amplifier by monitor circuit monitoring for amplifier; Pressure relay 4 is used for detecting the origin pressure in the train supply air line, and sends signal to anti-skid device main frame 1, and anti-skid device main frame 1 is controlled the operation of whole system according to the air feed situation and stopped.
