Traffic sign wireless broadcast device

The invention relates to a traffic sign wireless broadcast device, in particular, a transmitter is arranged in an indication unit on a road, and a receiver is arranged in the traveling vehicle to read and compare the information in the transmitter and broadcast the information, thereby Remind driving to drive carefully.

At present, when driving on a road, various traffic signs are provided on both sides of the roadside, which can provide information such as road name, speed limit, direction, warning, indication, etc., and the indicator is constructed in the Republic of China for 93 years. The new type M249165 "Structural Improvement of Guide Signs" announced on November 1st includes a shaft consisting of two or more telescopic rods with a pivotal device and plate Fixing and fixing; a plate body pivotally connected to the telescopic rod at the top end of the rod body by the pivoting device; accordingly, the plate body is pivotally connected to the top end of the rod body by the pivoting device to form a guiding sign, The multi-section telescopic rod of the rod body adjusts the length of the guiding sign, and the board body is separated from the rod body by the pivoting device to make it convenient to carry; but the guiding sign has only the function of visual indication. However, it may be limited by the influence of the font of the guide sign itself being too small, the color is faded, or the terrain environment of the road, the blockage by trees or the like, or the influence of the weather, such as the darkness of the sky, the rainy weather, Lack of light, or The traveling too fast will cause the driver failed to see the clear indication of its contents, but will cause problems of drivers, so the conventional guiding signs in the use There are many disadvantages mentioned above.

In view of the above, in view of the above-mentioned traffic sign on the road, the present invention provides a traffic sign wireless broadcast device, which is provided with a transmitter, which is provided with a chip, and the chip has a first built-in a receiver capable of reading first information in a wafer of the transmitter, the receiver being provided with a sounding element; a global satellite positioning unit integrated in the receiver and providing a second information; processing The unit is built in the receiver and electrically connected to the global satellite positioning unit, and compares the second information with the first information, and the result is played through the sounding element.

The above transmitter is disposed on an indicating unit.

The first information is any one or a combination of the indication unit related information, the latitude and longitude position of the indication unit, the road direction belonging to the indication unit or the warning level of the indication unit, and the second information is the current global positioning unit of the satellite positioning unit. Any one or combination of coordinate positions, directions, or speeds.

The processing unit compares the current coordinate position, direction or speed of the global satellite positioning unit with the direction of the pointing unit read by the receiver and the direction to which it belongs, selects the indicating unit in the same direction, and follows the pre-selected warning. The level is played through the sounding component.

The transmitter is an RFID radio frequency identification tag, an IEEE 802.11 wireless network transmitter or a ZigBee wireless network transmitter.

The invention has the following advantages:

1. The invention is provided with a transmitter in the indicating unit on the road, and has built-in related information for the driver's vehicle to pass through, and can read and broadcast to remind the driver of the attention.

2. The information in the transmitter of the present invention can be updated at any time to provide up-to-date road information.

3. The transmitter of the present invention is not affected by the font size of the guiding unit itself being too small, the color is faded, or the terrain environment of the road is affected by the obstacles of trees or the like, or the influence of the weather, such as the darkness of the sky. , rainy days, lack of lighting, or the speed of driving is too fast, so that the driver can clearly and accurately know the information content provided.

The first figure is a schematic view of the invention used in a vehicle traveling on a road.

The second figure is a structural configuration diagram of the present invention.

First, referring to the first figure and the second figure, the present invention includes an indication unit (1), a transmitter (2), a receiver (3), a global satellite positioning unit (4), and a processing unit (5). ,among them:

The indicating unit (1) can be set as a sign of various shapes and marked with relevant indication content, and is provided on the two sides of the road or one side of the one-way road.

The transmitter (2) is disposed on the indication unit (1), and the transmitter (2) can be an RFID radio frequency identification tag, an IEEE 802.11 wireless network transmitter or a ZigBee Wireless network transmitter, this embodiment uses an RFID radio frequency identification tag as an illustration. The transmitter (2) is provided with a chip (21), and the chip (21) has built-in indicator unit (1) related information and an indication unit. (1) The first information of the latitude and longitude position, the road direction belonging to the indicating unit (1) or the warning level of the indicating unit (1), and the first information content in the wafer (21) is continuously updated.

a receiver (3) placed in the vehicle (A) on the road and capable of reading the first information in the wafer (21) of the transmitter (2), the receiver (3) being provided with a sound Element (31).

The Global Positioning Unit (GPS) (4), which is integrated into the receiver (3), provides second information on the coordinates, direction and speed at which the vehicle (A) is currently located.

The processing unit (5) is built in the receiver (3) and electrically connected to the global satellite positioning unit (4), which is based on the current coordinates, direction and reception of the vehicle (A) The position of the indicating unit (1) read by the device (3) is compared with the direction of the road to which it belongs, and the indicating unit (1) in the same direction as the vehicle (A) is selected, and the sounding element is transmitted according to the warning level selected by the driver in advance. (31) Play the results read to remind the driver of the attention.

In use, as shown in the first figure, the receiver (3) is placed in the vehicle (A), and when the vehicle (A) travels close to the position of the indicating unit (1) on the road, the vehicle (A) The receiver (3) in the receiver (3) reads the chip (21) in the transmitter (2) of the indicator unit (1) on the road, and receives the chip (21) of the transmitter (2). The signal is processed by the processing unit (5) of the receiver (3), and then transmitted through the sounding list. The element (31) broadcasts the content of the related information comparison result; for example, the indication unit (1) related information, the latitude and longitude position where the indication unit (1) is located, the road direction belonging to the indication unit (1), or the indication unit (1) The first information of the warning level, and through the global satellite positioning unit (4), the second information of the coordinate position, direction and speed of the current vehicle (A), and the location of the indication unit (1) and the associated The roads are compared and the same direction indicator unit (1) is selected to obtain the correct road information and to guide the driver to the correct road so that the driver can fully grasp and understand the road information; The driver of the vehicle (A) can pre-select the warning level of the broadcast, and when the processing unit (5) of the receiver (3) compares the warning level of the indicating unit (1) in the first information, the indicating unit of the matching level is compared. (1) Relevant information can be played through the sounding unit (31) of the receiver (3) to display the information result, so as to remind the driver to clearly grasp all the information on the road to ensure driving safety.
