Abstract

The utility model relates to a speech alarming device of intelligent determining height of bridges, which can cause vehicles to obtain a voice prompt that the height of the vehicles passes beyond the height of the bridges when the vehicles in a safe distance before the vehicles pass through the bridges, and drivers can be prompted that the bridges can not pass through the front bridges. Only the height of the vehicles passes beyond the height of the bridges, the drivers can be advised and promoted that the height of the vehicles passes beyond the height the bridges before the vehicles pass the bridges, and the vehicles can not pass through the bridges. When the height of the vehicles not passes beyond the height of the bridges, the vehicles can pass through the bridges, and cue signals are not sent out. The warning and prompting distance between the vehicles and the bridges can be optionally arranged according to requirements. The utility model comprises two parts of a radio transmitter, and a radio receiver, wherein, the inner part of the radio transmitter is composed of a transmitter module, a height setting switch, an encoder, a transmitter power supply, and a transmitting antenna.

Description

Intelligent Recognition bridge height phonetic warning device

Technical field

The utility model relates to a kind of Intelligent Recognition bridge height phonetic warning device, particularly discerns acousto-optic, the phonetic warning device of road and bridge height about a kind of radio controlled fully-automatic intelligent.

Background technology

Along with the development of China's urban road multilevel traffic and the raising of category of roads, increasing viaduct, pedestrian's street crossing overline bridge are increasing, the accident that simultaneous superelevation motor vehicle hits bridge also gets more and more, the quality of bridge and life-span are subjected to serious threat and damage, make the property of country suffer serious loss, in today of national economic development high speed development, it is important that the safety problem of Urban Bridge becomes all the more.Be to use the method for bridge height nameplate now in China, the bridge height nameplate is placed on the pontic of bridge both sides, carries out the height mark with Chinese character and numeral above, with this motor vehicle is carried out the height prompting, does not also have this series products of the present utility model at present.

The utility model content

At the problems referred to above, the purpose of this utility model provides a kind of Intelligent Recognition bridge height phonetic warning device, and it has the function of full-automatic identification, acousto-optic voice prompting, can make the motor vehicle that this attention device has been installed in by a safe distance before the bridge, obtain a voice suggestion of the band flash of light of superelevation, prompting driver the place ahead bridge can not pass through, thereby the driver can in time be stopped, avoid hitting the generation of bridge accident.

For achieving the above object, the utility model is design like this: it is made up of radio transmitter and radio receiver, radio transmitter inside by transmitter module, highly switch, scrambler, emitting antenna, transmitter supply are set and form, switch (4) target setting height highly is set, to transmitter module (3) outupt coded signal, transmitter module (3) is to aerial launching code electric wave signal according to the height that sets for scrambler (5); Be positioned in the radio transmitter machine box, radio receiver inside is by receiver module, demoder, the height selector switch, flash alarm circuit, sound circuit, loudspeaker, receiving antenna, the receiver power supply composition is positioned in the machine box of radio receiver, wherein receiver module (8) receives described coded signal, through demoder (9), the signal of code translator (10) output is selected for height selector switch (11), lead to or disconnected according to described object height, the signal of code translator (10) output is transferred to flash alarm circuit (12), sound circuit (13), loudspeaker (14) is reported to the police.The two large divisions forms altogether; radio transmitter is placed on the bridge main body that will protect or on the light pole or electric pole of bridge; the selection of this distance is meant the distance of Gong the safety shut-down that need reserve; it is indoor that radio receiver 2 is placed on motor vehicle driving; when motor vehicle enters the radio wave coverage of transmitter emission; receiver can send corresponding sound and light alarm signal, and the prompting driver brakes immediately.

The utility model is owing to adopting above design, and it has the following advantages: motor vehicle is warned abundant interior the obtaining in advance of safety shut-down distance.2, automatically discern bridge height and flash and voice suggestion 3, have only the motor vehicle of superelevation before the bridge that passes through, to be apprised of, to point out driver's vehicle superelevation just now, can not pass through, make the driver can obtain prompting and parking in time in advance, when the vehicle of superelevation does not pass through, then do not send cue, all be subjected to prompting when avoiding and make driver's numbness, still cause the accident, 4, the alarm and prompt distance between motor vehicle and the bridge can set arbitrarily on demand by all bridges.5, adopt encoder to guarantee the correctness of identification automatically and the reliability of anti-various interference.6, easy to use.

Description of drawings

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a circuit control synoptic diagram of the present utility model

Embodiment

As shown in Figure 1, the utility model comprises

radio transmitter

1 and 2 two parts compositions of radio receiver, its radio transmitter 1 inside by, transmitter module 3, highly switch 4, scrambler 5, transmitter supply 6, emitting antenna 7 are set and form, radio receiver 2 inside are made up of receiver module 8, demoder 9, code translator 10, height selector switch 11, flash alarm circuit 12, sound circuit 13, loudspeaker 14, receiver power supply 15, receiving antenna 16.

The height of radio transmitter 1 is provided with switch 4 and is made up of a plurality of switches, promptly can single setting also can a plurality of bridge height be set, because the height of target bridge is fixed, so just using one of them switch usually selects to set, when when representing the switch connection of this bridge height, scrambler 5 is just by the coded signal of the setting that switch 4 highly is set to transmitter module 3 output special code types, transmitter module 3 is by the coding electric wave signal of emitting antenna 7 to the spatial emission special carrier frequency, after receiving coded signal by receiving antenna 16, receiver module 8 in the radio receiver 2 delivers to demoder 9, give code translator 10 by sending a dc level signal after demoder 9 decodings, the flat signal of code translator 10 output DCs is selected output for height selector switch 11, height selector switch 11 is the corresponding switch connection of height handle and the shutoff of limit for height as required, behind the selecteed switch connection dc level signal of code translator 10 outputs is delivered to flash alarm circuit 12 and sound circuit 13, flash alarm circuit 12 sends the blinking light signal, sound circuit 13 sends the voice signal of prerecording and delivers to loudspeaker 14, loudspeaker 14 sends voice suggestion sound, and sound and light signal points out the driver to stop simultaneously like this.Power supply 6 is the power supply of radio transmitter 1, and power supply 15 is the power supply of radio receiver 2,

Used all circuit are prior art in radio transmitter 1 in the utility model and the radio receiver 2; so its concrete annexation and circuit no longer describe in detail; it is a switches set with height selector switch 11 that switch 4 highly is set in the above-described embodiments; in concrete actual product, can omit; directly in circuit, make product at the fixed of a certain height; whether therefore switch 4 highly is set exists in actual product with height selector switch 11; do not influence protection domain of the present utility model, emitting antenna 7 and receiving antenna 16 can be external also can be built-in or be printed on the printed circuit board (PCB) in the above-described embodiments.Do not influence protection domain of the present utility model.
