Accompanying drawing explanation
The structural representation of a kind of one fast-assembling type train approach warning system that Fig. 1 provides for the utility model;
The use schematic diagram of a kind of one fast-assembling type train approach warning system that Fig. 2 provides for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe detail of the present utility model and algorithm in detail:
As depicted in figs. 1 and 2, light fast-assembling one fast-assembling type train approach warning system of the present utility model 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 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of sensor, can comprise a plurality of sensors.When train wheel will send time-domain signal from sensor 3 tops through out-of-date sensor 3, this time-domain signal is sent to the direction judging unit of master board 4, by direction judging unit, judged, then encoded device coding is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.Wireless receiving handler is the interphone that has installed Signaling Processing Unit additional, receive after the signal that main frame sends, directly if voice signal amplifies and broadcasts by loud speaker, if the different suggestion voice of function-driven that then code signal decode according to a preconcerted arrangement broadcasts.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.
Preferred emission unit frequency makes it to be more suitable for the inside and outside transmission in tunnel, alerting signal in the situation that not adding wireless relay, the unobstructed transmission distance >1.5Km in field, in worst single line electrified railway tunnels more than 800 meters.Substantially can meet the safety precaution needs that daily line construction is safeguarded.
