Summary of the invention
The purpose of this invention is to provide a kind of one fast-assembling type train approach warning system, solved the problem that above-mentioned prior art exists.
A kind of one fast-assembling type train approach warning system, comprised main frame, and sensor, wherein, described main frame has also comprised handle, high-frequency emission module, master board and power supply, described master board has also comprised the direction judging unit, coder, binary pair heartbeat module and voice operation demonstrator; Described sensor and described main frame are combined into an integral body, for when train wheel from sensor top through out-of-date transmission time-domain signal, described time-domain signal is sent to described direction judging unit; The described time-domain signal of described direction judgment unit judges, send to described coder by described time-domain signal; Described coder is sent to described binary pair after described time-domain signal is encoded; Described binary pair triggers described voice operation demonstrator according to the time-domain signal after different codings, after the time-domain signal shaping after described voice operation demonstrator will be encoded, sends to described high-frequency emission module; Described high-frequency emission module is amplified the time-domain signal after shaping and launch.
Further, one fast-assembling type train approach warning system provided by the invention, also comprise: the wireless receiving handler, after the signal sent for Receiving Host, if voice signal directly amplifies and broadcasts by loud speaker, if the different suggestion voice broadcast of function-driven that then code signal decoded according to a preconcerted arrangement.
Further, one fast-assembling type train approach warning system provided by the invention also comprises: the Timer Controlling signal generator, and for sending at regular intervals a heartbeat signal, thus the mode of operation of Test Host.
Further, one fast-assembling type train approach warning system provided by the invention, sensor, adopt high temperature resistant, noncontact, fast response time, switching frequency to reach the sensor of 300Hz.
Further, one fast-assembling type train approach warning system provided by the invention also comprises: micro-displacement sensor, and for detection of described main frame shift position whether.
The one fast-assembling type train approach warning system that provides of application the invention described above, volume is little, lightweight, firmly, carries, quick and easy for installation.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of one fast-assembling type train approach warning system provided by the invention;
The use schematic diagram that Fig. 2 is a kind of one fast-assembling type train approach warning system provided by the invention.
The specific embodiment
Describe detail of the present invention and algorithm in detail below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, light fast-assembling one fast-assembling type train approach warning system of the present invention has comprised main frame 7, sensor 3, high strong magnetic steel 6 and wireless receiving handler 8.Wherein, main frame 7 has comprised again handle 1, high-frequency emission module 2, master board 4 and power supply 5.Wherein, master board 4 has also comprised the direction judging unit, coder, and binary pair heartbeat module and voice operation demonstrator (attached not shown in FIG.), sensor 3 can be one group of sensor, can comprise a plurality of sensors.When train wheel will send time-domain signal from sensor 3 tops through out-of-date sensor 3, this time-domain signal is sent to the direction judging unit of master board 4, by the direction judgment unit judges, then encoded device coding is delivered to binary pair, binary pair triggers voice operation demonstrator according to different codings, and the signal of voice operation demonstrator amplifies and launches through high-frequency emission module 2 again through shaping.Timer Controlling signal generator on main frame 7, coder send at regular intervals " heartbeat " signal of a coding and launch to clearance envelope.The wireless receiving handler is the interphone that has installed Signaling Processing Unit additional, after receiving the signal that main frame sends, if voice signal directly amplifies and broadcasts by loud speaker, if the different suggestion voice broadcast of function-driven that then code signal decoded according to a preconcerted arrangement.Be provided with " heartbeat " detection, low voltage judgement alarm system.Can predict in time the mode of operation of main frame.
Native system main frame 7 is integrated with rail sensor 3, high strong magnetic steel 6, adopts high strength magnet steel mounting means, and 5-10 completes installation second, has reduced installation personnel length of the halt in orbit, has increased the safety of installation personnel.Volume is little, and lightweight (2.3kg) is easy to carry and firm.
Sensor, adopt high temperature resistant, noncontact, fast response time, switching frequency reaches the good quality sensor of 300Hz, this sensor can detect the Train Approaching that is greater than 200KM/h speed.The operating ambient temperature of sensor :-25-150 ℃, make it reliable operation under the great environment of the winter or summer temperature difference.
The preferred emission unit frequency makes it to be more suitable for the inside and outside transmission in tunnel, and alerting signal is not in the situation that add wireless relay, the unobstructed transmission distance in field > 1.5Km, in worst single line electrified railway tunnels more than 800 meters.Substantially can meet the safety precaution needs that daily line construction is safeguarded.
The recipient processor function is strong, easy to carry.Can determine and be equipped with different handler quantity according to on-the-spot actual needs.
System has the uplink and downlink train and enters and leave judgement and the full Chinese speech prompt facility that guard plot, main frame low voltage, main frame contact are interrupted, main frame comes off (antitheft, tamper-proof).
Native system also micro-displacement sensor is set, effectively prevent artificial dismounting.
