As a kind of embodiment, a pair of high directivity electric whistle at described headstock top is installed on the top of driver's cab one end headstock, and two high directivity electric whistles are installed dorsad.
As another kind of embodiment, a pair of high directivity electric whistle at described headstock top is installed on respectively the top of forward and backward two ends headstock, points to separately the place ahead of this headstock and installs.
A kind of situation is that the high directivity electric whistle at described headstock top is installed on the lateral mid-point at headstock top.
In the another kind of situation, the high directivity electric whistle at described headstock top is installed on respectively a horizontal relatively side at headstock top, installs in the accessible position, the place ahead on locomotive top.
Described locomotive head top is provided with the head lamp of long distance illumination.
As prioritization scheme, after described vehicle power, also seal in constant voltage power suspply.
A kind of embodiment, the power amplifier of described audio loop is with master cock.
Another kind of embodiment, series connection control switch between the power amplifier of described audio loop and the high directivity electric whistle.
Described power amplifier is provided with volume adjustment device.
The utility model has carried out the locomotive warning system transformation on the fundamental significance first, when guaranteeing to finish according to the rules caution and signal transfer function, utilizes the electric whistle of high directivity, has significantly reduced environmental noise.

The specific embodiment
The present invention is further described below in conjunction with accompanying drawing: as shown in Fig. 1 ~ 6, locomotive limit ring electric whistle warning system comprises a pair of high directivity electric whistle 3 that is installed in the locomotive head top, vehicle power 5 and the master cock in the car; The high directivity electric whistle 3 that is installed on the headstock top is connected to the mouth of power amplifier 11, and described power amplifier 11 is linked into vehicle power 5, consists of audio loop.
High directivity electric whistle 3 has the audio frequency electric property that meets the railway ministerial standard, and sound sends and to concentrate on the dead ahead, and little to the diffustivity of both sides, the sound that both sides are caused pollutes also little.
A kind of embodiment is, as shown in Figure 1, 2, a pair of high directivity electric whistle 3 at described headstock top is installed on the top of driver's cab 13 1 end headstocks, and two high directivity electric whistles 3 are installed dorsad.
Another kind of embodiment, such as Fig. 3,5,6, a pair of high directivity electric whistle 3 at described headstock top is installed on respectively the top of forward and backward two ends headstock, points to separately the place ahead of this headstock and installs.
Such as Fig. 3, the high directivity electric whistle 3 at described headstock top is installed on the lateral mid-point at headstock top.
Another kind of situation, such as Fig. 4,6, the high directivity electric whistle 3 at described headstock top is installed on respectively a horizontal relatively side at headstock top, installs in the accessible position, the place ahead on locomotive top.When before high directivity electric whistle 3 obstacle being arranged, sound reflection will cause the diffusion of sound, thereby can't satisfy the requirement of environmental protection.
