Description
Technical field
The utility model relates to railway automation signal control field, is meant a kind of redundant each other rail circuit receiver especially.
Background technology
At present, the station track circuit microelectronics receptor of Chinese Railway is widely applied, the transition of forward microelectronics technology, in the 25Hz phase detecting track circuit, replace two relays of binary, 50Hz phase detecting track circuit in urban track traffic, all adopt electronic receiver, current microelectronics receptor adopts the unit structure more, and reliability is low, influences conveying efficiency, or adopt two cover hardware to constitute the redundant fashion of " 1+1 ", i.e. track section of two identical receptor parallel control, this mode can significantly improve system reliability, but reception facilities quantity is multiplied, cause cost to raise, increased number of devices and also strengthened maintenance workload.
Current microelectronics receptor needs the outside to provide the 24V direct supply as working power, in engineered, need solve constant voltage dc source separately, has increased quantities, and engineering is difficult for implementing.
In the 25Hz phase detecting track circuit in order to finish the damage in insulation of adjacent two sections, need the identification phase place, must adopt the purpose made power supply panel, export one tunnel local signals that differ 90 degree phase places with track-circuit signalling and drive two relays of binary, cause in power supply panel circuit complexity, cost height and the practice efficient low.
The utility model content
In order to address the above problem, the utility model is to provide a kind of redundant each other rail circuit receiver, increases the problem that cost raises to solve pair reception facilities quantity that cover hardware formation " 1+1 " redundant fashions cause.
The technical solution that the utility model adopted is: a kind of redundant each other rail circuit receiver is provided, comprise: first receptor, second receptor, comprise logic main frame and the parallel operation that signal processing function is identical in described two receptors, the signal of first track section is imported with the parallel operation of the second redundant receptor as the main frame of first receptor respectively and is imported, and the signal of second track section is respectively as the main frame input of second receptor and the parallel operation input of first receptor of redundancy; The main frame output of first receptor and the parallel operation output-parallel of second receptor drive first track relay, and the parallel operation output of first receptor and the main frame output-parallel of second receptor drive second track relay.Described first receptor, the main frame of second receptor, parallel operation are worked simultaneously, output signal drive track relay in parallel.
Two receptors heat is equipped with redundant each other, when separate unit receptor fault, but as the receptor maintenance work of its parallel operation, thereby improve the reliability of equipment, reduced the influence that maintenance brings driving after the breakdown of equipment.
Described receiving device both can have been used in 25Hz or the 50Hz phase detecting track circuit, can be applicable in the half wave track circuit again.The receiving device that is used for phase detecting track circuit adopts the track circuit derived reference signal as the core processing unit power supply.The simplified apparatus external interface, easy to implement in the transformation.
The receiving device that is used for the 25Hz phase detecting track circuit changes the locally supplied power source's signal in the 25Hz phase sensitive rail circuit receiver into self section sending end track signal, utilizes the sending end signal to finish judgement to the receiving end signal phase place.No longer need locally supplied power source, thereby simplified the power supply panel circuit, reduced cost, improved power supply panel efficient.
Description of drawings
Fig. 1 constitutes two-shipper parallel operation theory structure block diagram;
Receiving device internal circuit configuration block diagram in Fig. 2 phase detecting track circuit.
The specific embodiment
For clearly demonstrating the scheme in the utility model, provide preferred embodiment below and be described with reference to the accompanying drawings.
In this embodiment, redundant devices comprises two receptors each other, and first receptor belongs to the equipment of first section; With second receptor, belong to the equipment of second section, as shown in Figure 1.
By above-mentioned connection mode, each receptor is except that processing self section received signal, the received signal of another section of synchronous processing, during two any one faults of receptor, two sections all can maintenance work, under the condition that does not increase equipment, realized the redundancy of " 1+1 ", reduced because the influence that breakdown of equipment brings to transportation.
Wherein first receptor and second receptor include main frame and parallel operation, wherein, main frame and parallel operation possess identical function, and have independently IO interface, inlet circuit, output circuit, a buffer circuit, as shown in Figure 2, signal input port adopts the high resistant design, reduces owing to reduce the variable quantity of the track-circuit signalling that causes after the access parallel operation because of receptor inlet resulting impedance; Output interface adopts buffer circuit, avoids forming after the two-way parallel connection the mutual short circuit between output interface.
Every receptor adopts a cover core processing unit to finish the demodulation of main frame and parallel operation signal, judgement and output control, and the two hardware of core processing unit and two software are checked, and guarantee the safety of output.
The receptor that is used for phase detecting track circuit, utilizing the reference power supply of input (is the local signal power supply in the 25Hz phase detecting track circuit, or adopt the track power supply as the reference source), it is the core processing unit module for power supply that the rectification of process transformation rectification module transformation forms stable 24V direct supply.
The receiving device that is used for the 25Hz phase detecting track circuit adopts this section sending end track signal as the reference signal source.Be connected to the reference signal output port by sending end signal with track circuit, gathering computing by the signal waveform synchronous with receiving short signal obtains, receiving end deviates from the angle of sending end signal, after exceeding certain limit, be judged as because the invalid signals that the adjacent signals intrusion causes after the insulation joint breakage, stop the output of control relay, realize inspection phase place.
For the scheme of being set forth among the utility model embodiment, all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
