Abstract
The present invention discloses an instant messenger about speedway condition, which includes a road condition information emitting device and vehicle information receiving device. The instant messenger has benefit effects as follows: firstly, the instant messenger can receive the road condition information through the road condition information emitting device at certain places, and plays corresponding road condition information with voice playing method; secondly, the instant messenger can update road condition information and load advertisement in the way of wireless data transmitting; thirdly, the instant messenger can receive alarm information sent by adjacent police car, ambulance and trouble vehicle, and plays corresponding content with voice.
Description
Technical field
The present invention relates to a kind of driving road-condition prompting device.
Background technology
Present increase along with China's highway mileage, improved the efficient of transport by road, the paces of modernization construction have been accelerated, rate is also high but the accident on the highway takes place frequently, how to reduce the accident rate on the highway, ensure the unobstructed of highway, it is the important topic that solution is badly in need of in traffic control department always, the analysis of causes at current expressway traffic accident generation, wherein real-time road condition information is depended merely on the warning sign that traditional light and reflectorized material are made, can not cause driver's hig diligence, effect is more bad at night or in the very low inclement weather of visibility, some special circumstances of some special road sections or appearance on the way can not in time be informed the driver, also are the reasons that causes the accident and take place.
Summary of the invention
The purpose of this invention is to provide a kind of express highway intelligent traffic information sound prompt device.
The objective of the invention is to realize in the following way: a kind of expressway information messenger, comprise traffic information emitter and on-vehicle information receiving trap, it is characterized in that: described traffic information emitter comprises data encoder, radio transmitter and power supply; Data encoder output termination radio transmitter, power output end connects radio transmitter; Described on-vehicle information receiving trap comprises wireless data transceiver module, cpu central processing unit, storer, code switch, D/A, audio power amplifier circuit; The output termination cpu central processing unit of wireless data transceiver module, the output terminal of cpu central processing unit connects wireless data transceiver module, storer, D/A respectively, the output termination cpu central processing unit of storer, the output termination cpu central processing unit of code switch, the output termination audio power amplifier circuit of D/A.
Described power supply comprises solar cell, accumulator, charge-discharge protection circuit, intermittent power supply circuit; Solar cell output termination charge-discharge protection circuit, charge-discharge protection circuit output termination accumulator and intermittent power supply circuit, accumulator output end connects charge-discharge protection circuit, the output termination radio transmitter of intermittent power supply circuit.
The present invention has following beneficial effect, and the one, can receive the traffic information of fixed location traffic information emitter emission, and use the speech play corresponding road condition information; The 2nd, but can upgrade traffic information and carrying advertisement with the mode of wireless data transmission; The 3rd, near the information warning warning message that police car, ambulance and fault vehicle send receiving, and use the speech play content corresponding.
