Described information acquisition module 22 is arranged on the fog section that takes place frequently, and uses wireless signal control.Transmit a signal on the display board at 150m place, to the reserved brake snubbing time of vehicle, adopt the effectively high problem of solving road construction bracing wire cost of controlled in wireless.
Fig. 4 and Fig. 5 disclose the partial function circuit structure diagram of center-control processing unit 10 of the present invention, intelligent detection unit 20 and display unit 30.
Technical scheme of the present invention is mainly used on urban road, city expressway, highway, highway, can play car because the inclement weather reasons such as change in weather cause the intelligent warning function of traffic congestion and traffic hazard.This inclement weather Intelligent Measurement display system is inner Single-chip Controlling, can select solar storage battery power supply, and can change warning content according to setting, adopt high brightness, low energy consumption light emitting diode, meets the requirement of current conservation-minded society, low-carbon environment-friendly, energy-saving and emission-reduction.
Technical scheme of the present invention also has following technique effect:
(1) native system can be worked under outdoor low cold weather, does not need artificial monitoring, saves manpower, and detection information is passed back constantly.Visibility sensor 222 per minutes detect once automatically to weather conditions, to the weather that may occur, as the rainy day, snow day, greasy weather or this is compared with atrocious weather, comprise that the weather such as haze weather, sandstorm can carry out Intelligent Measurement, when measuring weather outside when abnormal, the very first time can be reported back system host the signal gathering, main frame is after moment identification, judge, adjust outside display sign, so that prompting vehicular traffic is taken care travel at once.The excellent part of this system is, volume is little, and power consumption is little, and energy-conserving and environment-protective do not need civil power work, rely on solar cell just can normally work completely.The present invention adopts technical grade module and single chip circuit, can be competent at the severe cold weather in northeast completely.The weather conditions checkout equipment having in the market all easily several ten thousand, the hundreds of thousands easily of import, and be all meteorological special main equipment, in the improper large-area applications of transit equipment.Cost is high, complex structure, and inclement weather Intelligent Measurement display system of the present invention has been filled up a blank of warning traffic equipment, and to driving, pedestrains safety has great significance.
(2) note control, live signal gathers automatically, and transmitting is returned automatically.This system display sign content can manually be controlled according to client's subjective desire.Because being system, sleet mist variable sign automatically identifies control, so send conversion command all can to when being switched to manual mode client's mobile phone at every turn, client also can directly send order at far-end with mobile phone allows label force to change, client is after sending involuntary conversion, rugged surroundings detection display system can be made as the first priority by client's note order, the preferential customer command that shows, shielding detects automatically.
Intelligent detection unit principle of work is as follows:
1, greasy weather visibility detection module principle of work
Greasy weather visibility detection module is mainly for detection of the greasy weather in weather and haze weather, and cardinal principle is as follows:
Utilize in Infrared laser emission and receiving course the degree value being stopped by airborne particle or water smoke to judge whether to occur anomalous weather (greasy weather or haze sky), transmitting terminal is infrared laser head, is receiving end photoresistance apart from 600mm place.Under normal weather, the Infrared signal that receiving end receives is fixed value, in the time occurring stopping, the Infrared signal that (having mist or haze) receiving end receives starts decay, and in the time that light attenuation arrives specified value, visibility detection module thinks that the greasy weather (haze sky) occurs, then by greasy weather (haze sky) signal feedback to master routine, master routine, through single-chip microcomputer processing, amplifies signal, starts LED.
2, sleet intelligent identification module principle of work
Sleet intelligent identification module, mainly for detection of the rainy day and the snow day that occur in weather with identification, mainly detects principle as follows:
Utilize " with the inductance sleet moisture detection sensor (i.e. probe) of analog signals output ", when rainwater or snow-broth were fallen " the sleet inductance moisture detection probe " of this module when upper, resistance value rising.In the time there is no the weather of rainwater or ice and snow, this detection numerical value is fixed value, in the time having a certain amount of rainwater or snow-broth to fall in detection probe, resistance value exceedes fixed value, module think that weather snows or rain, and sleet sky detection module is by the signal feedback gathering to master routine, and master routine is through single-chip microcomputer processing, signal is amplified, start variable autoluminescence display board.
In the time that winter, outdoor temperature was below zero degrees celsius, prevent from, because snow sky or sleet freeze inductance moisture detection probe, causing the illusion of always reporting to the police, can address the above problem by heating unit.Once, each startup ensures the inductance moisture detection probe being frozen by snow-broth to melt, and prevents false alarm in i.e. this heating unit startup per hour.
In sum, inclement weather Intelligent Measurement display system is at collection and feedback information through sleet sensor and visibility sensor, through the computing of single-chip microcomputer internal logic, intellectual analysis, signal amplification is transmitted to relay, and the intelligence that has realized LED alert display unit is switched, realize unattended, the features such as nobody detects in real time, and this system has accurately simple, and rate of false alarm is low.
The above; only for preferably embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
