The present invention relates to an intelligent traffic display, and more particularly, the traffic information collected in real time to produce a color on the display to display the traffic situation in real time, or the traffic weak to easily recognize the traffic obstacles It relates to an intelligent traffic display that can protect the.

Korean Utility Model Publication No. 1994-1406 related to road traffic signs (Notice date: March 16, 1994 designation name: road traffic sign, known as 'prior art 1') as shown in Figure 1 In order to display the character display (12, 13, 14, 15) of the destination, the vehicle traveling direction display (1, 2, 3, 4) at the next intersection is set at the predetermined position of the road traffic sign. In addition, the plurality of direction display panels 5, 6, 7, and 8, which display specific vehicle traveling directions on each vehicle traveling direction display, can be selectively detached and replaced as necessary.

Such a prior art 1 is particularly convenient for first-time drivers or foreign drivers, by installing a vehicle traveling direction display plate at a predetermined intersection at a predetermined position, which can prevent traffic congestion or accidents in advance, and also the vehicle traveling direction. By making the display panel detachable using screw-type, slip-type, adhesive, etc., it is easy to exchange and attach, so that even when the contents of the road traffic change from time to time, the vehicle corresponding to the changed part can be carried out without making a new road sign. It is possible to replace only the direction display plate, thereby reducing the cost.

Here, binary CDMA among the protocols adopted by the communication module 43 of the present invention will be briefly described.

In general, the WLAN communication is widely used because various wireless APs, for example, a large number of devices are arbitrarily installed due to the characteristics of the ISM band. Therefore, the three-dimensional interference problem occurs in apartments, offices, and roadsides of high-rise buildings. .

One way to efficiently solve these problems is to use binary CDMA technology that is resistant to noise and interference. Binary CDMA technology solves existing problems such as structure complexity, high cost, and high power consumption by binarizing and transmitting the modulated signals of various levels generated by the existing multi-code CDMA scheme by externally converting them into TDMA signal waveforms. It can be a solution of the communication technology.

In addition, the binary CDMA adopted in the present invention is specialized by combining the advantages of CDMA (strong noise) and TDMA (ultra-high speed, low power), and guarantees the transmission quality by actively avoiding the surrounding frequency interference using the frequency hopping technique. In addition, it is a long-range wireless transmission / reception protocol capable of providing multimedia, sensor, and voice convergence services within a certain area.

Various data such as the operation state of the various external vehicles described above, road traffic status, and communication with the vehicle are exchanged. AP1, AP2, AP3, and AP4 are each wireless APs.

In the step S120 of transmitting to the wireless module, the received information is transmitted to the sign control module by the wireless module of the communication module 43 as described above.

In addition, in the sign control step S130, the sign control module corresponds to the control module 41 of the control means 40, and controls the optical fiber light source generator 50 according to a program mounted on the control module 41. The above-described information is input so as to express a color corresponding to the display 52.

In the determination and signal lighting steps (S151, 153, and 155), when the vehicle's traveling speed is 20 km per hour or less (S141), 21 to 40 km (S143), and 41 km or more, according to a program installed in the control module 41. Corresponding to the case (S145), the corresponding red signal turns on (S151), yellow signal turns on (S153), and green signal turns on (S155), respectively.

The determination program according to the present invention is first moved from a low speed to a high speed, and when it is not 41 km or more, it is returned to the sign control module S130 again.

In the speed change determination step (S160), after the lighting is completed, if there is no speed change, the process is terminated.

The flow chart as described above is not a one-time and has a structure that is repeatedly circulated.

In particular, the communication module 64 receives a signal from the traffic information collection and reception device (T) installed near the crosswalk and interlocks with the control module (63) to indicate that the traffic weakness is near. Can be sent to.

The communication module 64 is interworked with an external traffic information collecting and transmitting apparatus and a wireless communication protocol arbitrarily selected from binary CDMA, Zigbee, Wipi, and WiBRO. Preferably, a binary CDMA scheme is applied.
