Description

The device of transmitting high speed highway fog lamp Detection ﹠ Controling signal

Technical field

The utility model is a kind of device of transmitting high speed highway fog lamp Detection ﹠ Controling signal, belongs to automation remote observation and control technology field.

Background technology

More than 10,000 kilometer of the existing highway of China, and just at high speed development, the road surface Facilities Construction is perfect substantially, the traffic capacity greatly improves, but infrastructure drops into imbalance, and heavy road surface is built, but safety management facility relative deficiency, the domestic and international report that extensive traffic accident took place in the greasy weather is a lot.For head it off, some highways have begun to have set up fog lamp and have induced traffic system, and this system has played very big effect to safety traffic, but the operation of this system has brought a series of problems thereupon: the life-span of 1) how to improve lamp; 2) break down when lamp, how to detect accurately and reliably and to pass to Surveillance center; 3) a series of problems such as energy-conservation.

Summary of the invention

For overcoming the above problems, the utility model provides a kind of and does not need private cable, optical cable and lay special-purpose communication network, just the device of the convenient and swift transmitting high speed highway fog lamp Detection ﹠ Controling signal of energy.

The utility model is realized by following scheme: the device of transmitting high speed highway fog lamp Detection ﹠ Controling signal, it comprises power supply, the fog lamp signal supervisory instrument, the fog lamp control device, central processing unit, interface arrangement, it is characterized in that fog lamp signal supervisory instrument and fog lamp control device link to each other with central processing unit by interface arrangement, central processing unit links to each other with bluetooth wireless devices: fog lamp operating state detection signal inputs to central processing unit after the A/D conversion, the Back ground Information with detection signal and this fog lamp under the control of central processing unit constantly sends by bluetooth wireless devices; The fog lamp control signal that bluetooth wireless devices receives is under the control of central processing unit, by the switching of fog lamp control device control fog lamp.

The device of described fog lamp Detection ﹠ Controling signal is preferably disposed in continuously arranged each fog lamp bar.

The communication distance of bluetooth wireless devices between 10-100m, and highway generally every 50m left and right sides continuous regular the fog lamp device is set, within bluetooth communications range.The utility model utilizes the characteristics of Bluetooth short distance radio communication just, by endless relay transmission signals between bluetooth wireless devices, realizes the long-distance transmissions of fog lamp Detection ﹠ Controling signal.Be solidified with the Back ground Informations such as geographical position of this fog lamp in the flash memory of each bluetooth wireless devices, each fog lamp operating state detection signal and Back ground Information constantly send to bluetooth wireless devices in the adjacent fog lamp device by bluetooth wireless devices, receive this fog lamp of its adjacent fog lamp bluetooth wireless devices transmission and the detection information and the Back ground Information of other fog lamp simultaneously, broken hair is not seen off, form the bluetooth line of endless relay transmission data, by existing wired or wireless communication network, be sent to the central computer of Surveillance center, can monitor the fog lamp working condition in real time.In like manner, the control signal that Surveillance center sends, the bluetooth line through endless relay transmission data passes on each fog lamp, the opening and closing of control fog lamp.If bluetooth wireless devices occurs can't realizing normal communication unusually in the fog lamp device that has, the bluetooth wireless devices in other fog lamp device can be selected an optimal path in the bluetooth communication scope, avoid bad lamp, realizes normal communication.

Advantage of the present utility model is:

1, device hardware is simple in structure.Because multiple interfaces such as wireless receiving and dispatching, central processing unit, USB mouth that at present existing monolithic Bluetooth chip is integrated, therefore the hardware circuit that with the Bluetooth technology is carrier platform is simple, fog lamp on the highway and bluetooth wireless devices are integrated to be easier to, and realizes that remote measurement and control is also more or less freely.

2, enforcement is cheap.With regard to the price of present Bluetooth chip, about 100 yuan of RMB, make great efforts to reduce production costs in each production commercial city, and this will help the extensive popularization of blue-tooth technology, system cost is lower than traditional transfer of data medium, and this will remove the obstacles for the large-scale promotion application of Bluetooth technology.System integration cost is very low, and after system builds up, its safeguard and carrying cost very low.

3, communication distance is fit to.Its power output of the wireless transceiver of bluetooth equipment minimum is 10 milliwatts, sends and the scope of accepting is 10m.By adjusting its power output of wireless receiving and dispatching, can change the distance that sends with acceptance, but having defined the peak power output of wireless transceiver, Bluetooth specification surpasses 100 milliwatts, the transmission of corresponding maximum and receiving range are in 100m.Highway fog lamp distance is within bluetooth communications range.

4, global communications band, the versatility of sharing is good.Frequency range (2.4GHz) and frequency hopping that Bluetooth technology adopts the whole world to share; its strong interference immunity, institute's emitted power is the mW level, belongs to micropower and is unlikely to other system is produced harmful interference; do not require special protection yet, do not need to apply for channel specially yet to radio control department.The soul of Bluetooth technology is what its whole world was unified, the technical standard of exploitation, and the shared policy of world's bluetooth organization knowledge property right.It can unify the technical standard of each producer, businessman, realize the interconnection and interflow of various products and mutually between compatibility, avoid causing " technology is unordered " and the huge waste of social resources in market competition.
