Embodiment 1: the utility model core component is a signal processor, its circuit and general-purpose locomotive signal processor basic identical (seeing Fig. 4, Fig. 5), but for rail vehicle, can only adopt the power supply of 24V power supply, therefore increase a switching power circuit (as Fig. 3).Its principle of work is as follows:

This system adopts the digital signal processing mode to finish the analysis and the identification of cab signal.Signal is changed into digital signal by isolation level promptly finishes analog to digital conversion.Signal behind analogue to digital conversion is to DSP, and the analyzing and processing by DSP finishes signal identifies the current signal that receives.

Decomposite low-frequency information for shift frequency class cab signal by minute frequency band filtering and signal envelope, also with regard to the lamp model.Here adopted and believed that detection technique guarantees the correctness of signal identification.

For ac counting class cab signal is directly to identify pulse and finish the identification of signal and decipher out corresponding information code type and drive point lamp system at interval by the analysis of neural network method again by minute frequency band filtering and envelope.

Self check that native system adopted and protection system link not only can detect the fault with protection system self, can also realize the detection to signal lamp, thereby guarantee the reliable and stable utilization of native system.

The rail vehicle signal adopts standard eight shows signal machines, and the signal indicator that promptly uses locomotive to adopt only is that 24 volts of 8W get final product with replacing bulb.

The locomotive sensor adopts the used locomotive inductor of locomotive.

The supply current of rail vehicle signal is 24 volts, thereby machine intimate adopted the DC/DC of a wide input range, i.e. 24/5DC/DC conversion goes out this DC/DC, can be operated in the input direct current 18-36 volt change of voltage scope and be output as 5 volts.

Not only adopted filtering for purifying this current system of power supply stream, suppressed circuit, guaranteed that this system works is reliable and stable but also increased surge voltage.

Embodiment 2: the signal processor among the embodiment 1 is linked to each other with general-duty JK-2Hg logout instrument (only will import power supply changes 24V into), get final product emotionally condition of track record garage.

Embodiment 3: the signal processor among the embodiment 1 is linked to each other with automatic stop arrangement, and (its circuit diagram is seen Fig. 6, Fig. 8) is applicable to area and the unit that technology such as remote, flow dispersion, ground signal data analysis are weak.

Described type rail vehicle automatic stopping device mainly partly is made up of control capsule, warning box, knob box, electric empty vent valve, time-delay reservoir, shut down relay, speed contact etc.

1, control capsule:

Control capsule is the major equipment of this device.Its execution cycle property is watched out for self-stopping whole control actions.Its element circuit mainly contains start-up circuit, 1SJ circuit, 2SJ circuit and auto-recovery circuit and low speed inspection, high speed warning circuit.

The box face be provided with unlock button, speed switch, counting machine fenestra, power fuse seat and with connector of external relation etc.

This device after 7 seconds, forces braking in continuous alarm.Enter locking states for alleviating circuit again midway after preventing to stop, only push unlock button, carry out manual release, equipment is restored.In this course, counting machine is counted once automatically, can read from the counting machine fenestra.

This device is taked effective glancing impact as the driver in warning is during 7 seconds, utilize the speed contact, can automatically terminate the parking effect.Speed switch K connects or excises the switch of this effect.

2, be provided with two cover variation tone Chinese percussion instrument circuit in the warning box, two kinds of forms arranged: use two woofers or overlap sounder reverse graft to a loud horn in the use one.

3, button box:

Button box is provided with acknowledgment button, emergency stop push button, yellow light-emitting diode etc.When this device was in positioning states, button box UD lighted, and then UD extinguishes when signal alarm occurring, at this moment pushed acknowledgment button and just can make this device obtain vigilant effect.Run into emergency situation, push emergency stop push button and can make the rail locomotive emergency braking.

4, electric empty vent valve: it is that this device is carried out self-stopping parts.Its controlled box control.After its electromagnetic valve got electric excitation, vent valve was opened.The train pipe causes full car emergency braking rapidly to the atmosphere air draft.

5, time-delay reservoir:

Behind the electromagnetic valve coil loss of excitation, after the time-delay reservoir can make time that vent valve continue to open 45-60 second in order to the protection emergency braking, the alleviation midway that causes electromagnetic valve mistake dead electricity to occur owing to breakdown of equipment.

6, shut down relay:

It is the middle power electromagnet relay of winding point more than, during automatic train stop, by the conversion of its contact, realizes necessary mechanical and electrical protection, for example stucco, and unloading, shelves draw, return zero etc.The type of relay and operating voltage can be selected to use according to dissimilar needs.

7, speed contact:

Be loaded on control capsule inside, link with tachogenerator, when the driver adopted effective braking and low cruise, the cycle that automatically terminates reported to the police and the automatic train stop effect, reports to the police immediately when overspeed.

Mode:

1, this device is when cab signal shows half red/half Huang, red light or enters side line, entering the main track parking should send periodically audible alarm and require the driver periodically to push acknowledgment button, the driver is not as pushing acknowledgment button, automatic train stop after 7 seconds then, also can with the rail vehicle signal combination, as once vigilant use, the driver is not according to acknowledgment button, and it is more than then to report to the police.

2, on the locomotive that is unkitted the rail vehicle signal, after automatic stopping device can receive and be located at ground-surface attachment point information, award periodically and report to the police, or independent the use, do not combine and make unmanned vigilance device with any accepting device, give periodically to report to the police.

3, this device time of fire alarming regulation is as follows: cycle warning pitch time is 4 ± 1 seconds, report to the police to the automatic train stop onset time be 7-8 second.Report to the police and finish to adopt four kinds of modes: (1) continous way rail vehicle signal becomes permission and shows; (2) utilize the mano-contact of speed low speed contact or train pipe decompression to excise; (3) regularly excision; Time is 22 ± 5 seconds; (4) overspeed alarming speed drops to excision warning just often.

4, the driver is when normal brake activation, and automatic stopping device is not answered misoperation.

5, this device adopt the electric braking mode.
