The other end of tachogenerator (Em) output is connected with the mid point of relay (2) K2, the mid point of relay (3) K4 and the other end of relay (3) coil,
The other end of relay (1) coil is connected with the normally closed point of relay (3) K5, and the mid point of K5 is connected with the normally closed point of relay (2) K2,
The other end of relay (2) coil is connected with the normally closed point of relay (3) K4,
The normal battle of the negative pole of storage battery (E) and relay (3) K6, be connected with the normal battle of relay (2) K3 and the normal battle of relay (1) K1,
The positive pole of storage battery (E) is connected with the end of display lamp (L1), (L2), (L3),
The other end of display lamp (L1) is connected with the mid point of relay (1) K1,
The other end of display lamp (L2) is connected with the mid point of relay (2) K3,
The other end of display lamp (L3) is connected with the mid point of relay (3) K6.
Compared with prior art it is simple in structure for the utility model, can further improve automotive performance, can make chaufeur and pedestrian judge the moving velocity of the other side's vehicle and pursuit-type vehicle accurately and effectively, the preparation of thought and time has been arranged in advance, avoid delay of response, error in judgement and the traffic accident that takes place can also be compressed chaufeur not drive over the speed limit in the speed limit highway section is a kind of comparatively ideal device that traffic accident takes place that reduces.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is an electrical block diagram of the present utility model.
Among the figure: Em, tachogenerator, 1, relay, 2, relay, 3, relay, 4, power wheel, E, storage battery, L1, display lamp, L2, display lamp, L3, display lamp.
Referring to accompanying drawing, the utility model it mainly by: tachogenerator (Em), relay (1), relay (2), relay (3), power wheel (4), storage battery (E), display lamp (L1), display lamp (L2), display lamp (L3) are formed, and it is characterized in that:
Power wheel (4) is affixed with the axle of tachogenerator (Em), and tachogenerator (Em) is a prior art, repeats no more here, and an end of tachogenerator (Em) output is connected with an end of the coil of relay (1), relay (2), relay (3),
The other end of tachogenerator (Em) output is connected with the mid point of relay (2) K2, the mid point of relay (3) K4 and the other end of relay (3) coil,
The other end of relay (1) coil is connected with the normally closed point of relay (3) K5, and the mid point of K5 is connected with the normally closed point of relay (2) K2,
The other end of relay (2) coil is connected with the normally closed point of relay (3) K4,
