Description

System and method for judging that a vehicle will notify other vehicles when it does not follow signs

A vehicle information notification system and method, in particular, it refers to a system and method for notifying other vehicles when it judges that the vehicle will not follow the signs.

Usually, traffic lights or accident-prone intersections will be equipped with signal lights to control vehicles with staggered driving directions so that vehicles with staggered driving directions will not pass through the intersection at the same time to avoid traffic accidents.

At present, the way to control the signal lights is usually to periodically switch between the stop signal and the pass signal. However, the control method of periodically switching the signal is often easy to cause traffic jams in intersections with significant traffic flow at different times. Therefore, most of the signal lights at such intersections can be set for different time periods Switch lights in different cycles.

In addition, in order to prevent vehicles from following signs, such as vehicles ignoring signs that show stop lights and crossing over intersections, therefore, at some intersections, for example, junctions that are prone to accidents or have a large number of violations, in addition to installing sign lights It will also set up cameras to ban illegal vehicles.

However, even if the camera is illegally banned, there may still be vehicles that do not follow the signs. When such vehicles cross the intersection, the driving of the vehicles that follow the lights may still fail to respond and cause traffic accidents.

In summary, it can be seen that in the prior art, there has been a problem that vehicles that did not follow the signs for a long period of time tend to make the driving on the signs less responsive and cause traffic accidents. Therefore, it is necessary to propose improved technical means to solve this problem. problem.

In view of the prior art's problem that driving under the sign is difficult to respond to vehicles that do not follow the sign at the intersection, the present invention discloses a system and method for notifying other vehicles when the vehicle will not follow the sign, where:

The system for judging that a vehicle will not notify other vehicles when it does not follow the signs disclosed in the present invention at least includes: a plurality of street lamps acting in different driving directions respectively detect the speed of each vehicle in each driving direction and transmit to the signs Control device; when the signal control device judges that the speed of the target vehicle is too fast, it changes the signal of the direction of travel in the driving direction according to the speed of the target vehicle and the distance between the target vehicle and the stop point, where the target vehicle is driving One of the vehicles in the stopping direction in the direction; the sign control device sends a notification message to each street lamp acting in the direction of traffic; each street lamp acting in the direction of traffic sends a reminder message to each vehicle traveling in the direction of traffic.

The method disclosed in the present invention for judging that a vehicle will not notify other vehicles when it does not follow the signs, the steps include at least: a plurality of vehicles, each vehicle is driving in one of a plurality of driving directions; a plurality of street lamps, each street lamp functions In at least one driving direction, it is used to detect the vehicle speed of each vehicle traveling in each driving direction; the sign control device is used to receive the vehicle speed of each vehicle transmitted by each street lamp, and determine which vehicle is traveling in the driving direction When the speed of the target vehicle in the stopping direction is too fast, the lights belonging to the direction of travel in the driving direction are changed according to the speed of the target vehicle and the distance between the target vehicle and the stopping point, and a notification message is sent to each of the directions of travel Street lights, the street lights acting on the traffic direction are used to send reminder messages to the vehicles driving in the traffic direction when receiving the notification message.

The system and method disclosed by the present invention are as above. The difference from the prior art is that the present invention detects the vehicle speed by each street lamp and transmits the detected vehicle speed to the sign control device.

The content is sufficient for any person skilled in the relevant arts to easily fully understand and implement the technical means applied to solve the technical problems of the present invention and implement accordingly, thereby realizing The achievable effect of the invention.

The invention allows the sign control device to obtain the speed of the vehicle through the street light, and can change the sign light of the passing direction and remind the vehicle of the passing direction through the street light when it is judged that the vehicle traveling in the stopping direction may be forced to pass without stopping. Driver on the road.

The following describes the system operation of the present invention based on the system architecture diagram of the "picture 1" of the present invention, which judges that the vehicle will not follow the signs and notifies other vehicles. As shown in "Figure 1", the system of the present invention includes a street lamp 150, a sign lamp 110, and a sign control device 200.

The signal lamp 110 is usually installed on the left or right side of the intersection or road surface, such as a traffic light. In addition, the signal lamp 110 may also be a level crossing signal lamp, but the signal lamp 110 is not limited to the above.

The signal lamp 110 acts on the driving direction, and is responsible for displaying the signals indicating that the driving direction in the driving direction is passable and forbidden, that is, the driver of the vehicle traveling in the driving direction can see the signal lamp 110 The number of lights can be seen from the lights to see whether the driving direction is currently passable or prohibited. In the present invention, the signal lamp 110 may only display a signal indicating that it is passable or prohibited, for example, when the signal lamp 110 is a traffic light, it indicates that the passable signal is a green light or a yellow light, indicating that the traffic is prohibited The light is red.

The driving direction mentioned in the present invention is the direction that the vehicle 400 needs to follow. For example, in Taiwan, the vehicle 400 needs to drive on the right side of the road surface. Therefore, generally, the right side of the two-way traffic road is the driving direction of the vehicle. In the present invention, the driving direction of the traffic light 110 indicating the traffic light is called the traffic direction, and the driving direction of the traffic light 110 showing the traffic prohibition signal is the stop direction. Among them, the signal lamp 110 acting on the traffic direction is also referred to as the "first signal lamp" in the present invention; the signal lamp 110 acting on the stopping direction, that is, the signal lamp 110 not acting on the traffic direction, In the present invention, it is also referred to as "the second signal light".

The sign lamp 110 may be connected to the sign control device 200 through a wired or wireless network, or may be connected to the sign control device 200 through a connection line. The present invention is not particularly limited. The signal lamp 110 can receive data or signals transmitted by the signal control device 200. In more detail, the signal lamp 110 can receive the control signal transmitted by the signal control device 200, and display the corresponding signal according to the received control signal. Wherein, the control signal may be a signal indicating the current light signal to be displayed, or a signal indicating the light signal to be displayed in a period of time in the future, and the invention is not particularly limited.

In some embodiments, the signal lamp 110 can also transmit data or signals to the signal control device 200. For example, the signal lamp 110 can detect the set position to obtain the corresponding position data, and can transmit the detected position data to the signal control device 200; in addition, the signal lamp 110 can also read in advance The stored sign identification data, and can transmit the read sign identification data to the sign control device 200. Among them, the position data mentioned in the present invention is data that can represent the position of a specific object, such as latitude and longitude coordinates, etc., but the present invention is not limited to this; the sign identification data is the data that can represent the corresponding sign lamp 110 Generally speaking, the sign identification data is a unique value, usually formed by arbitrarily arranging any number of words, letters, numbers, and symbols.

The street lamp 150 acts in the driving direction and can provide illumination, that is, the main lighting range of the street lamp 150 falls in the driving direction. Generally speaking, the street lamp 150 can be installed on the road surface on either side of the left and right sides of the traveling direction, but the present invention is not limited thereto. In the present invention, the street lamp 150 acting in the passing direction is also referred to as "first street lamp", and the street lamp 150 acting in the stopping direction is also referred to as "second street lamp".

The street lamp 150 is responsible for detecting the speed of the vehicle 400 passing through the street lamp 150 in the driving direction of action. In some embodiments, the street lamp 150 can also detect the traffic flow in the driving direction, that is, calculate the number of vehicles passing the street lamp 150 within a certain period of time. Since the technology of detecting the vehicle speed and traffic volume at a fixed point is already known, the present invention will not repeat them.

In addition, the street lamp 150 can also detect the installed position to obtain corresponding position data, and the street lamp 150 can also read pre-stored street lamp identification data.

The street lamp 150 can be connected to the vehicle 400 passing through the street lamp 150 through a wireless network, and can transmit data or signals to the connected vehicle 400, and the street lamp 150 can also be connected to the sign control device 200 through a wired or wireless network, and can be transmitted The data or signal is given to the sign control device 200, and can receive the data or signal transmitted by the sign control device 200. For example, the street lamp 150 may transmit the detected position data, the read street lamp identification data, and/or the detected vehicle speed and traffic volume to the sign control device 200. The street lamp 150 may also receive the notification message sent by the sign control device 200, and may send a prompt message or a warning message to the vehicle 400. Among them, the notification message contains enough data for the street lamp 150 to select and generate a prompt message or a warning message.

In more detail, after receiving the notification message sent by the sign control device 200, the street lamp 150 may generate a prompt message or a warning message according to the data in the received notification message. For example, the notification message may include speed limits and actions Data and other data, when the action data in the notification message received by the street lamp 150 is expressed as a broadcast, the street lamp 150 can generate a prompt message and can send the generated prompt message to each vehicle 400 driving in the direction of traffic When the action data in the notification message indicates a warning, the street lamp 150 can generate a warning message and can send the generated warning message to the vehicle 400 whose detected vehicle speed exceeds the speed limit in the notification message. For another example, the notification message may include speed limit and specific street lamp identification data/location data of one or more street lamps 150. When the street lamp 150 receives the notification message, it may determine any street lamp identification data included in the notification message/ Whether the location data is the same as its own street lamp identification data/location data, if not, the street lamp 150 can generate a prompt message, and can send the generated prompt message to each vehicle 400 driving in the driving direction; and when the notification message When the included lamp identification data/position data is the same as the lamp identification data/position data of the lamp 150 itself, the lamp 150 can generate a warning message and can send the generated warning message to the detected vehicle speed exceeding The speed limit vehicle 400 in the notification message. However, the street lamp 150 selects the method for generating the prompt message or the warning message according to the data in the notification message and the data contained in the notification message is not limited to the above. Wherever the street lamp 150 can determine the way to generate and send the prompt message or the warning message Both data and materials can be used in the present invention.

The signal control device 200 is responsible for judging that the vehicle 400 traveling in the stop direction may not follow the signal, change the signal of the signal light 110 acting on the traffic direction, and send a notification message to all connected to the signal control device 200 Or some street lights 150. The sign control device 200 further includes a communication module 210, a determination module 220, a control module 230, a signal transmission module 240, and an additional presentation module 260.

The communication module 210 can be connected to each street lamp 150 through a wired or wireless network, and can transmit data or signals to the street lamp 150, and can receive the data or signals transmitted by the street lamp 150. For example, the communication module 210 can receive the street lamp 150 The transmitted vehicle speed, traffic flow, location data, street lamp identification data, etc. may also send notification messages to one or more street lamps 150. In some embodiments, the communication module 210 can also be connected to a traffic server (not shown) through a wired or wireless network, and can transmit data or signals to the traffic server.

The judgment module 220 is responsible for judging whether all the vehicle speeds received by the communication module 210 are normal, or judging whether any one of the vehicle speeds received by the communication module 210 is too fast, that is, judging the street lights acting in various driving directions 150 The speed detected is too fast. In the present invention, the vehicle 400 traveling in the stop direction and judged by the judgment module 220 that the vehicle speed is too fast is called a target vehicle.

The determination module 220 can also determine whether the target vehicle may not follow the sign based on the speed of the target vehicle, that is, whether the target vehicle may forcefully pass through the stop point, for example, the determination module 220 may determine the target based on whether the speed of the target vehicle decreases Is it possible for the vehicle to stop before the stopping point. Among them, the stop point mentioned in the present invention may be a stop line on the road surface or the location of a specific location, the location where the signal light 110 is set, the location where the location of the signal light 110 is projected into the driving direction, etc. The invention is not limited to this.

In more detail, the determination module 220 can determine whether the target vehicle may not follow the sign based on the distance between the signal lamp 110 and the target vehicle's speed in the traveling direction of the target vehicle, for example, based on the target vehicle The acceleration and the distance between the target vehicle and the signal lamp 110 determine whether the target vehicle may stop before the stopping point. If it is, the judgment module 220 can determine that the target vehicle will be likely to follow the sign. If not, it can be determined that the target vehicle will Do not follow the signs. The method for determining the separation distance between the signal lamp 110 and the target vehicle by the determination module 220 may be that the determination module 220 pre-stores the position data of each stop point and the position data of the street lamp 150 that can be connected to the sign control device 200 , And when it is judged that the speed of the vehicle is too fast, according to the position data of the street lamp 150 transmitting the fast speed and the driving direction set in the street lamp 150 transmitting the fast speed and closest to the street lamp (the street lamp 150 transmitting the speed too fast) The position data of the stop point is calculated, and the distance between the target vehicle that is too fast and the stop point (the stop point closest to the driving direction set by the street lamp 150 that transmits the fast speed and closest to the street lamp 150 that transmits the excessive speed) is calculated. ; It is also possible that the judgment module 220 reads the position data of the street lamp 150 transmitting the excessively fast vehicle speed according to the identification information of the street lamp transmitted together with the excessively fast vehicle speed when determining that the vehicle speed is too fast, and Too fast speed of the street light 150) The position data in the set driving direction and closest to the stop point of the street light 150 that transmits the over fast speed calculates the target vehicle that is too fast and the stop point (the street light 150 that transmits the over speed speed) The separation distance between the set driving direction and the closest to the stop point of the street lamp 150 transmitting the excessively fast speed. However, the manner in which the determination module 220 determines the separation distance is not limited to the above.

The determination module 220 may also generate a notification message when it is determined that a target vehicle may not follow the sign, and send the notification message to each street lamp 150 acting on the traffic direction through the communication module 210. In some embodiments, the determination module 220 may also send a notification message to the street lamp 150 acting on the driving direction of the target vehicle through the communication module 210, that is, a street lamp acting on the stopping direction by sending a notification message.

The control module 230 is responsible for changing the distance between the indicator lamp 110 and the target vehicle according to the speed of the target vehicle and the distance between the signal lamp 110 and the target vehicle when the judgment module 220 determines that the speed of the target vehicle is too fast The signal control device 200 is connected and displays the signal number of the signal light 110 indicating the signal that can pass, that is, changing the signal number of the signal light 110 acting on the traffic direction, and changing the signal light 110 acting on the traffic direction In order to display the signal indicating that the passage is prohibited. In more detail, the control module 230 may be based on the vehicle speed of the target vehicle and the street lamp 150 that transmits the excessively fast vehicle speed determined by the determination module 220 and the driving direction set in the street lamp 150 that transmits the excessively fast vehicle speed and is closest to the transmission The interval between the stopping points of the over-speed road lamp 150 predicts the time when the target vehicle reaches the stopping point, and can generate the setting signal of the signal lamp 110 that controls the direction of travel according to the predicted time, and through the signal transmission module 240 The generated setting signal is transmitted to the traffic signal lamp 110, so that the traffic signal lamp 110 changes the signal according to the received setting signal, so that the traffic signal of the traffic signal lamp 110 can be The time predicted by the control module 230 is changed to display a signal indicating that no traffic is allowed, so that when the target vehicle does not follow the signal and passes the stop point, the signal 110 that originally displayed the signal indicating that it can pass is changed to the display. No traffic lights.

The control module 230 may also set the lights of each driving direction according to the traffic flow in each driving direction when the judgment module 220 judges that each vehicle speed transmitted by all street lamps 150 is normal. In more detail, the control module 230 can generate a setting signal that controls the signal lamp 110 acting in each driving direction according to the traffic flow detected by the communication module 210 acting on the street lamp 150 acting in each driving direction, and can The generated setting signal is transmitted to each signal lamp 110 through the signal transmission module 240, so that each signal lamp 110 displays the signal according to the received setting signal. For example, the control module 230 can determine the traffic volume in each driving direction , And can generate a setting signal indicating that the traffic lights in the driving direction with a large traffic flow for a long time can be passed, and a display signal indicating that the traffic lights in the traveling direction with a low traffic flow can display The setting signal with a shorter time of passing lights. Even, the control module 230 can generate a setting signal that shows that the ratio of the time of passing lights and the traffic flow in each driving direction is consistent.

The raising module 260 can take a violation photo containing the target vehicle, and send the captured violation photo to the traffic server through the communication module 210 to raise the target vehicle. In more detail, the presentation module 260 can obtain the time when the target vehicle predicted by the control module 230 reaches the stopping point, and can try to pass the included image capturing unit before the control module 230 predicts the time when the target vehicle reaches the stopping point 262 Taking a photo of a violation that includes the target vehicle, but the way the trigger module 260 triggers the shooting of the violation photo is not limited to the above.

Next, an embodiment is used to explain the operation system and method of the present invention, and please refer to "Figure 3A" for a flowchart of a method for judging that a vehicle will not notify other vehicles when it does not follow the signs mentioned in the present invention. In this embodiment, as shown in "Figure 2", the signal lights 110a to d are traffic lights installed at the intersection, and the signal control device 200 is installed near the intersection, but the present invention is not limited to the application to the intersection mouth.

During the operation of the present invention, the street lamps (150a~d) provided in different driving directions (first to fourth driving directions) can respectively detect the speed of vehicles (400a, b) in each driving direction, and can detect The measured vehicle speed is transmitted to the sign control device 200 (step 310).

After the communication module 210 of the sign control device 200 receives the vehicle speeds of the street lamps 150a-d, the determination module 220 of the sign control device 200 can determine whether the speed of the target vehicle is too fast (step 320).

If the judgment module 220 of the sign control device 200 determines that no vehicle speed is too fast, that is, the determination module 220 determines that the vehicle speeds received by the communication module 210 are normal, then the control module 230 of the sign control device 200 may Set the signal of each driving direction according to the preset value. If the judging module 220 judges that the speed of the target vehicle is too fast, the control module 230 may change the traffic signal according to the speed of the target vehicle and the separation distance between the target vehicle and the stop point (step 350). In this embodiment, it is assumed that the horizontal traveling direction (third and fourth traveling directions) in the "Figure 2" is the stopping direction, and the vertical traveling direction (first and second traveling directions) is the passing direction, The stopping point is the location of the signal lights 110a~d mapped to the driving direction. If the determination module 220 determines that the speed of the vehicle 400b detected by the street light 150c is too fast, the vehicle 400b is the target vehicle. The group 230 can generate a setting signal according to the speed of the vehicle 400b and the interval distance between the street lamp 150c and the position (stop point) of the sign lamp 110c, and the generated setting signal can be generated by the signal transmission module 240 of the sign control device 200 Transmitted to the signal lamp 110a acting in the first driving direction and the signal lamp 110b in the second driving direction, so that the signal lamp 110a/b acting in the first/second driving direction is based on the received settings The signal changes the displayed light signal from green light to yellow light sequentially and then to red light.

Similarly, when the determination module 220 of the sign control device 200 determines that the speed of the target vehicle is too fast, the determination module 220 can generate a notification message and send the generated notification message through the communication module 210 of the sign control device 200 The street lamps 150a, b acting in the traffic direction are given (step 361).

After receiving the notification message sent by the sign control device 200, the street lamp (150a/b) acting in the traffic direction can generate a reminder message and send the generated reminder message to the vehicle driving in the traffic direction 400a (step 365). In this embodiment, it is assumed that the central control computer (not shown) on the vehicle 400a traveling in the traffic direction can receive the prompt message sent by the street lamp 150a/b, and can convert the received prompt message into The voice message and the converted voice message are played to remind the driver in the vehicle 400a that there may be other vehicles crossing the red light in front of the intersection.

In this way, through the present invention, when the vehicle traveling in the stopping direction may not follow the signs, the driver traveling in the traffic direction can be notified in advance, so that the driver in the traffic direction can make preparations in advance to prevent the accident from being unresponsive.

In addition, the present invention may also follow the flow shown in "Figure 3B". The judgment module 220 of the sign control device 200 may also notify the generated notification when it is judged that the speed of the target vehicle is too fast (step 320). The message is transmitted to the street lamp 150c acting in the traveling direction of the target vehicle (step 371).

After the street lamp 150c acting in the traveling direction of the target vehicle receives the notification message sent by the sign control device 200, it can generate a warning message and send the generated warning message to the target vehicle (step 375). In this embodiment, it is assumed that a central control computer (not shown) on the vehicle 400b can receive the warning message sent by the street lamp 150c, and can convert the received warning message into a voice message and play the converted voice The message reminds the driver in the target vehicle to follow the signs.

If in this embodiment, the sign control device 200 further includes a warning module 260, then the warning module 260 may capture a violation photo containing the target vehicle when the target vehicle (vehicle 400b) is not following the sign or is speeding, and The captured violation photos are transmitted to the traffic server through the communication module 210 of the sign control device 200 to raise the target vehicle (step 380).

In the above embodiment, after the determination module 220 of the sign control device 200 determines whether there is a target vehicle whose speed is too fast (step 320), the determination module 220 may determine the target first as shown in the flow of "Figure 3C" The separation distance between the vehicle and the signal lamp 110c acting in the driving direction of the target vehicle (step 331), and it can be determined whether the target vehicle may not follow the sign based on the speed of the target vehicle and the determined separation distance (Step 335). In this embodiment, the determination module 220 is to determine the separation distance between the street lamp 150c and the signal lamp 110c which detect the speed of the target vehicle, and determine the target vehicle according to the target vehicle speed and the determined separation distance Is it possible to run a red light.

If the determination module 220 determines that the target vehicle may not follow the sign, the control module 230 may determine the target vehicle's speed and the separation distance between the target vehicle and the sign lamp 110c acting in the traveling direction of the target vehicle ( In this embodiment, the distance between the street lamp 150c and the signal lamp 110c that detects the speed of the target vehicle) changes the direction of the traffic signal (step 350), so that it will act on the vehicle 400b before passing the stop point. The signal displayed on the traffic signal lamp 110a/b is changed to a signal indicating that traffic is prohibited.

When the judging module 220 judges that the target vehicle may not follow the signs, the judging module 220 may also send the generated notification message to the street lights 150a, b (in the direction of traffic) through the communication module 210 of the sign control device 200 ( Step 361); and if the judging module 220 judges that the target vehicle is still likely to travel according to the sign, that is, the target vehicle can stop before the stopping point of the intersection, the judging module 220 can continue to track the target vehicle, that is, to judge again Whether the speed of the target vehicle is too fast (step 320), and it is determined whether the target vehicle may not follow the signs based on the speed of the target vehicle and the determined separation distance (steps 331, 335). In this way, it can be more accurately determined whether the vehicle traveling in the stop direction will not follow the signs.

In summary, it can be seen that the difference between the present invention and the prior art is that each street lamp detects the vehicle speed and transmits the detected vehicle speed to the sign control device. The sign control device determines that there is a vehicle When the speed of the vehicle is too fast, change the direction of the traffic lights, and notify the vehicles through the streetlights of the technical means of driving in the traffic direction. This technical means can solve the problems encountered by the prior art driving at the intersections. Vehicles that do not follow signs are easy to respond to the problem, and then achieve the technical effect of reminding drivers ahead of time whether there are vehicles that do not follow signs to reduce accidents.

In addition, the method of determining that a vehicle will not notify other vehicles when driving according to the sign can be implemented in hardware, software, or a combination of hardware and software, and can also be implemented in a centralized manner or with different components in a computer system Distributed in several interconnected computer systems.
