Description

Sign control system for emergency vehicles

The present invention relates to a semaphore control system, and more particularly to a semaphore control system for an emergency vehicle.

According to the research report, nearly 60% of traffic accidents occur in the intersection area every year in China. When hearing the whistle warning sound of an emergency vehicle (ambulance, fire engine or police car, etc.), it is not clear to passers-by. When the emergency vehicle travels and the direction of travel, it often continues to drive into the intersection area, so that there is often a traffic accident in which the emergency vehicle collides with other vehicles in the direction of travel when passing through the intersection area.

Although the Ministry of Communications will launch the "Smart Road Safety Plan", the intersections such as intersections and T-junctions will be upgraded to smart intersections. It is hoped that by setting up detection facilities such as short-wave radar at intersections and installing electronic signage at intersections. Let the vehicle drive to the first two or three seconds of the smart intersection, you can flash the sign in advance or display the image on the electronic signboard to remind the side of the intersection to have a car, in order to avoid or reduce the other direct collision with the lateral intersection. vehicle.

Since the purpose of the plan is to reduce the collision accidents of various vehicles at intersections, although the emergency vehicles have the priority of red light driving, if there is no special warning sign, the emergency vehicles are still prone to accidents when passing through the intersection area. In addition, the project uses short-wave radar to detect vehicles, with limited detection range and accuracy, and is unable to provide individual warnings for the passage of emergency vehicles. Moreover, the electronic kanban display design of the project can only inform the vehicle of the direction and cannot be used to predict the direction of the vehicle at the intersection area, so the effect of reducing the traffic accident of the emergency vehicle at the intersection is rather limited.

Accordingly, it is an object of the present invention to provide a stellar control system for an emergency vehicle that improves at least one of the disadvantages of the prior art.

Accordingly, the present invention is directed to an alarm control system for an emergency vehicle, which is adapted to indicate a traffic direction of a plurality of emergency vehicles, and includes at least one traffic light device adapted to be disposed in an intersection area through which the emergency vehicles pass, the traffic light The device includes a first traffic light device and a signal control device coupled to the first traffic light device. The first traffic light device can simultaneously display a plurality of traffic direction indicators for indicating the direction of travel of the emergency vehicles through the intersection region. The number control device stores a plurality of traffic direction indication symbols respectively for indicating a plurality of traffic directions, and the traffic directions indicated by the traffic direction indicators are straight traffic to a specific direction, and a specific direction is turned to a specific direction. The direction control device can be configured to receive a plurality of traffic direction indication control signals respectively corresponding to the traffic direction indication symbols stored therein, and are triggered by the traffic direction indication control signals to control the first The traffic light device simultaneously displays a plurality of traffic direction indicators for indicating the corresponding traffic direction.

The utility model has the advantages that the symbol control device can compare the line direction indication symbols and control the first traffic light device to simultaneously display the design of the traffic direction indication symbols, so that the passerby can be used according to the The traffic direction indicator displayed by the traffic light device at the intersection clearly indicates the relative traffic direction of the emergency vehicles when passing through the intersection area, and can clearly determine whether a courtesy action or how to polite is required.

The present invention will be further described with respect to the following examples, but it should be understood that this embodiment is for illustrative purposes only and should not be construed as limiting the implementation of the present invention, and similar elements are the same. The number is indicated.

Referring to Figures 1 and 2, an embodiment of the present invention for a control system for an emergency vehicle 800 is adapted to be mounted in a plurality of intersection areas 700, and when an emergency vehicle 800 passes through each intersection area 700, Each intersection area 700 indicates to the passerby the direction of travel of the emergency vehicle 800. The emergency vehicle 800 is, for example but not limited to, an ambulance, a fire engine, a police car, and other vehicles having a red light priority pass right, and the emergency vehicle 800 can be positioned by the satellite positioning system and output a positioning data, and can be activated. When the direction light is on, it sends a turn signal corresponding to the direction indicated by the direction light. The intersection area 700 is, for example but not limited to, an intersection type having four intersections 701, a T-junction type having a three intersections 701 and a Y-junction type, and a toroidal intersection type having a plurality of intersections 701. And other large intersection types with 701 at more than four intersections.

The number control system includes a plurality of traffic light devices 3 respectively installed in the intersection areas 700, and a remote control host 4 connected to the traffic light devices 3 via wired communication technology and/or wireless communication technology signals. In this embodiment, the remote control host 4 is disposed in an action monitoring center for coordinating the scheduling of the emergency vehicle 800.

Since the structure and function of the traffic light equipment 3 are the same, for convenience of description, only the traffic light equipment 3 installed in the intersection area 700 of an intersection type will be described as an example of its structure and function.

The traffic light device 3 includes a first traffic light device 31 and three second traffic light devices 32 respectively disposed at four intersections 701 of the intersection area 700, and a signal connected to the traffic light devices 31, 32. Control device 33. The traffic light devices 31 and 32 are horn devices that are generally disposed on the road and can generate a red light, a green light, and a yellow light. Since the traffic light devices 31, 32 are conventional components, they will not be described in detail.

Referring to Figures 2, 3 and 4, the number control device 33 stores a plurality of traffic direction indicator symbols 330 representing the direction of travel, and can perform steering processing of different traffic angles for one traffic direction indicator symbol 330 to obtain a plurality of separate directions. A post-steering direction indicator 333 representing a different heading direction. The manner in which the traffic direction indicator 330 is turned to obtain the afterward direction direction indicator 333 will be described later.

The traffic directions indicated by the traffic direction indicator symbols 330 are divided into three types of traffic types, such as a straight-line traffic type in a specific direction, a turn-through traffic type in a specific direction, and a transit traffic type in a specific direction. Each type of traffic is further subdivided into a plurality of traffic directions according to the type of the intersection area 700 corresponding thereto, wherein the traffic direction indicated by the traffic direction indicator symbol 330 of the straight-line traffic type in a specific direction can be classified as, for example, a rear car or Straight-line traffic to the incoming car, and the lateral direction of the car to the right or to the left; the direction of the direction indicated by the direction indicator 330 of the pass type of the specific direction can be divided into, for example, the rear right or left turn, right The left-hand turn or the left turn, and the left-hand turn or the right turn on the side of the car; the direction of the direction indicated by the traffic direction indicator 330 in the specific direction of the turn-by-pass type can be divided into, for example, the rear car, the opposite car, And the left and right sides of the car to turn around.

In this embodiment, the pattern of each of the traffic direction indicating symbols 330 is a line pattern extending in a specific direction, but in implementation, in other embodiments of the present invention, an arrow symbol extending in a specific direction may also be extended. The pattern of each of the afterward direction indicator 333 is the same as the pattern of the corresponding direction indicator 330, except that the direction of extension is different.

The signal control device 33 can receive the traffic direction indication control signal sent by the remote control host 4 to the first traffic light device 31 disposed in the respective intersection area 700, and the traffic direction indication control signal is stored with One of the traffic direction indication symbols 330 corresponds to one. The number control device 33 includes a symbol recognition unit 331, a symbol steering processing unit 332, and a symbol display control unit 334.

The symbol recognition unit 331 identifies the traffic direction indication control signal and compares the corresponding traffic direction indication symbol 330. The symbol steering processing unit 332 may be located on the left side, the right side, or the opposite side of the first traffic light device 31 according to the orientation of each of the second traffic light devices 32 located in the intersection area 700 with respect to the first traffic light device 31. At the intersection 701, the traffic direction indicating symbol 330 is aligned with the symbol recognition unit 331 to obtain a steering direction indication symbol 333 corresponding to the second traffic light device 32, so the symbol steering processing unit 332 will process the output of three post-steering direction indication symbols 333 corresponding to the second traffic light device 32, respectively.

The symbol display control unit 334 controls the first traffic light device 31 to display the traffic direction indication symbol 330 that the symbol recognition unit 331 compares, so that the first traffic light device 31 can indicate that the emergency vehicle 800 is at the intersection. When the area 700 is in transit, the direction of travel of the intersection 701 is relative to the intersection. In addition, the symbol display control unit 334 also synchronously controls each of the second traffic light devices 32 to display the corresponding post-steering direction indication symbol 333, so that each second traffic light device 32 can indicate that the emergency vehicle 800 is in the When the intersection area 700 is in transit, the direction of travel of the intersection 701 is relative to the intersection.

For example, when the symbol recognition unit 331 compares the traffic direction indication control signal, the traffic direction indication symbol 330 corresponding to the straight line passing through from left to right, that is, the traffic direction indication displayed by the first traffic light device 31. The symbol 330 is used to indicate that the emergency vehicle 800 will pass straight through the intersection area 700 from left to right with respect to the respective intersection 701. At this time, for the second traffic light device 32 located at another intersection 701 on the left side of the first traffic light device 31, the symbol steering processing unit 332 rotates the traffic direction indicator symbol 330 counterclockwise by 90 degrees to obtain a corresponding The steering direction direction indicator 333 is such that the second direction traffic indicator 333 displayed by the second traffic light device 32 on the left side of the first traffic light device 31 is used to indicate 701 with respect to the respective intersection. The emergency vehicle 800 passes straight through the intersection area 700 from the rear; for the second traffic light device 32 located at the intersection 701 on the right side of the first traffic light device 31, the symbol steering processing unit 332 will pass the traffic direction The indicator symbol 330 is rotated 90 degrees clockwise to obtain the corresponding afterward direction indicator 333, such that the second direction of the first traffic light device 31 is displayed by the second traffic light direction indicator 333. Is used to indicate that the emergency vehicle 800 is traveling straight through the intersection area 70 with respect to the intersection. 0; for the second traffic light device 32 located at the intersection 701 of the first traffic light device 31, the symbol steering processing unit 332 rotates the traffic direction indicator symbol 330 clockwise by 180 degrees to obtain a corresponding After the steering direction indication symbol 333 is turned on, the post-steering direction indication symbol 333 displayed by the second traffic light device 32 opposite to the first traffic light device 31 is used to indicate the location 701 with respect to the respective intersection. The emergency vehicle 800 passes straight through the intersection area 700 from right to left.

With this design, when the sign control device 33 receives the traffic direction indicating control signal for the first traffic light device 31 located at one of the intersections 700 of the intersection area 700, the comparison first corresponds to the first After the traffic direction indicator 330 of the traffic light device 31, the corresponding traffic direction indicator 333 is obtained for each second traffic light device 32 located at the remaining intersections 701 of the intersection region 700. . Then, the traffic light control devices 31 and 32 respectively display the corresponding traffic direction indicator 330 and the corresponding traffic direction indicator 333 so that the traffic lights 31, 32 can be located at the respective intersections. The passer at the place 701 clearly indicates the relative traffic direction of the emergency vehicle 800, and can immediately perform the parking dodge.

It should be noted that, in this embodiment, the intersection area is of a positive intersection type, so the symbol steering processing unit 332 rotates the traffic direction indication symbol 330 by 90 degrees and 180 degrees to obtain the direction of the steering direction. Indicia 333, but when implemented, when the intersection area 700 is not a positive intersection type, such as a Y-junction type, the angle of the direction indication symbol 330 can be adjusted according to the relative azimuth angle of the intersection 701. To obtain the post-steering direction indicator 333 for each intersection.

2, 4, and 6, in the embodiment, the symbol display control unit 334 controls the first traffic light device 31 and the second traffic light device 32 to dynamically display the traffic direction indicator 330 and the steering respectively. The rear pass direction indicator 333. The so-called dynamic display, for example, causes the traffic direction indication symbol in the form of a line and the backward traffic direction indication symbol to continuously disappear in the direction in which the direction is to be indicated, and disappears, and the traffic direction indication symbol and the original display direction are displayed. After the steering direction direction indicator begins to disappear, the display and synchronization of the other direction indicator and the subsequent direction indicator are synchronously displayed, thereby repeatedly repeating the direction indicator and the following directions. The direction indicator symbol achieves the purpose of dynamic display. Since there are many methods for generating dynamic vision of the displayed image, the implementation is not limited to the above dynamic display mode.

2, 3, and 5, the remote control host 4 can wirelessly receive the positioning data and the turn signal sent by the emergency vehicle 800, and can send the traffic direction indication control signal to each traffic light device 3. The remote control host 4 includes a vehicle positioning unit 41, a navigation unit 42, a turn determination unit 43, and a remote control unit 44. The vehicle positioning unit 41 has an electronic map indicating the intersection area 700, and can analyze the location data to locate the location of the emergency vehicle 800 in the electronic map.

The navigation unit 42 plans and displays a navigation route for the emergency vehicle 800 according to the electronic map, the navigation route is the position that the emergency vehicle 800 is positioned from the vehicle positioning unit 41, and starts to travel through the plurality of intersection areas 700. And the route of arrival to a destination, such as an accident scene or a medical institution. Since the navigation unit 42 plans the navigation route to be a conventional technique and has many ways, it will not be described in detail.

The turn determination unit 43 can analyze the turn signal transmitted by the emergency vehicle 800, and determine the turning direction of the intersection area 700 that the emergency vehicle 800 desires to pass and is to pass.

The remote control unit 44 analyzes the change in position of the emergency vehicle 800 to obtain the direction of travel and the speed of the emergency vehicle 800, and analyzes the navigation route according to the electronic map to obtain an intersection where the emergency vehicle 800 is about to arrive and pass. The area 700, the distance between the emergency vehicle 800 and the intersection area 700, and the direction of travel when the navigation route passes through the intersection area 700, and cooperates with whether the turn signal is received according to whether the turn signal is received, and the turn determination unit 43 determines the output. In the direction of the turn, it is determined whether the emergency vehicle 800 is to change the travel route at the intersection area 700 that is about to arrive.

When the remote control unit 44 determines that the traffic direction is not changed, it may determine that the distance between the emergency vehicle 800 and the intersection area 700 is less than a distance threshold, and/or the emergency vehicle 800 arrives at the intersection area 700. When the time is less than a time threshold, the traffic direction of the intersection area 700 is sent to the traffic light device 3 located in the intersection area 700 to transmit the corresponding direction indication control signal, so that the traffic light device 3 The number control device 33 controls the traffic light devices 31, 32 to display the corresponding traffic direction indicator 330 and the subsequent traffic direction indicator 333, respectively.

The remote control unit 44 determines that the emergency vehicle 800 wants to change the traffic direction in the intersection area 700 in the following three ways:

(1) The remote control unit 44 determines that the emergency vehicle 800 is in direct traffic in the direction of the intersection 700 to be reached according to the navigation route, but when the turn signal is received, the emergency vehicle 800 is determined. It is desirable to turn at the intersection area 700 to change the driving route.

(2) The remote control unit 44 determines, according to the navigation route, that the emergency vehicle 800 is in a passing direction in the passing direction of the intersection area 700 that is about to arrive, but does not receive the turning signal, and determines the emergency vehicle. 800 wants to go straight in the intersection area 700 to change the driving route.

(3) The remote control unit 44 determines, according to the navigation route, that the emergency vehicle 800 is in a passing direction of the intersection area 700 that is about to arrive, but the passing direction of the turning pass is different from the turning determining unit 43. When the turning direction is determined based on the turning signal, it is determined that the emergency vehicle 800 intends to change the turning direction in the intersection area 700 to change the traveling route.

The remote control unit 44 may change the transmission direction of the navigation route according to the changed traffic direction to the setting at the intersection when determining that the emergency vehicle 800 intends to change the traffic direction of the navigation route originally planned to pass through the intersection area 700. The traffic direction of the traffic light device 3 of the area 700 indicates a control signal, so that the signal control device 33 can control the traffic light direction indicators at the intersections 701 at the intersections 701 to display the traffic direction indicator after changing the traffic direction. 330 and the subsequent steering direction indication symbol 333.

When the present invention is used in the emergency control system of the emergency vehicle 800, the traffic light devices 3 can be respectively disposed in the plurality of intersection areas 700, and the remote control host 4 is set in a mobile monitoring center to enable the remote control. The host 4 signal is connected to the traffic light device 3 and the emergency vehicle 800. The remote control host 4 will begin positioning the emergency vehicle 800 when the emergency vehicle 800 issues an emergency traffic demand, and establish a navigation route to the destination, and will arrive at an intersection area 700 according to the emergency vehicle 800. Whether the turn signal is issued or not is determined whether the emergency vehicle 800 desires to change the originally planned traffic direction of the navigation route in the intersection area 700.

The remote control host 4 may determine, according to the electronic map and the navigation route, that the distance between the emergency vehicle 800 and the intersection area 700 to be passed is less than the distance threshold, and/or the time to reach the intersection area 700 is less than At the time threshold, the traffic direction indicating control signal is sent to the traffic light device 3 disposed in the intersection area 700. When it is determined that the emergency vehicle 800 wants to change the traffic direction in the intersection area 700, the corresponding traffic direction indication control signal is retransmitted according to the changed traffic direction.

The number control device 33 of the traffic light device 3 disposed in the intersection area 700 will instruct the control signal according to the traffic direction direction, and compare the traffic direction indication symbol 330 corresponding to the first traffic light device 31, and according to the With respect to the orientation of the second traffic light device 32 with respect to the first traffic light device 31, the steering process outputs the corresponding rearward traffic direction indication symbols 333 corresponding to the second traffic light device 32, respectively, and then synchronously controls the first traffic light device 31. The yellow signal light 311 displays the traffic direction indicator symbol 330, and the yellow number lights 321 that control the second traffic light devices 32 respectively display the forward steering direction indication symbols 333, and the traffic light devices 31 are enabled. 32 can clearly indicate the relative traffic direction of the emergency vehicle 800 to the passers-by at the intersections 701, so that the passers-by at the intersections 701 know whether the escort is required or how to greet the emergency vehicle 800.

Since the number control device 33 controls the traffic lights 31, 321 of the traffic light devices 31, 32 to display the traffic direction indicator 330 and the traffic direction indicator 333, respectively, The passerby at the intersection 701 performs the direction indication of the emergency vehicle 800, so that the traffic indication function of the red and green lights of the traffic light device 32 is not affected at all.

In addition, in this embodiment, the remote control host 4 is disposed in the action monitoring center, but in implementation, in another implementation manner of the present invention, the remote control host 4 may also be directly disposed in the Emergency vehicle 800.

Furthermore, in the embodiment, the signal control device 33 compares the traffic direction indication signal 330 corresponding to the traffic direction indication control signal to the first traffic light device 31, and then installs the phase according to the traffic direction indication symbol 330. The direction of each of the second traffic light devices 32 at the remaining intersections 701 relative to the orientation of the first traffic light device 31 will be compared with the direction indicator 330 of the traffic direction, and then the second traffic light devices 32 are controlled to display The respective steering direction direction indicator 333 is turned. However, in other implementations of the present invention, the number control device 33 does not need to steer the traffic direction indicator 330, and the yellow number of each second traffic light device 32 can be adjusted by pre-rotation. The installation angle of the light lamp 321 is, for example, in the intersection, the yellow number lamp 321 of the second traffic light device 32 located on the right side of the first traffic light device 31 is rotated 90 degrees clockwise, and then fixed and installed. The yellow signal light 321 of the second traffic light device 32 on the left side of the traffic light device 31 is rotated 90 degrees counterclockwise and then fixed, and the yellow number of the second traffic light device 32 opposite to the first traffic light device 31 is mounted. The lamp 321 is rotated 180 degrees in the clockwise direction and then fixed and fixed. By designing, after comparing the traffic direction indicator 330, the first traffic light device 31 and the second traffic light device 32 can be directly displayed. The traffic direction indicator symbol 330, since the yellow number lamp 321 of each second traffic light device 32 has been previously turned, the traffic direction indicator symbol 330 is displayed exactly for each The intersection of passers 701 indicates the direction of passage of the emergency vehicle 800.

Referring to FIG. 7, in implementation, if a plurality of emergency vehicles 800 pass through the intersection area 700 at a similar time, the remote control host (shown in FIG. 1) can control the traffic light device 3 at the first traffic light device. 31 and two or more of the traffic direction indicator symbols 330 are simultaneously displayed with the second traffic light device 32 to indicate the direction of travel for the emergency vehicles 800, respectively.

In summary, the stellar control device 33 of each of the traffic light devices 3 can control the traffic direction indication symbol 330 according to the traffic direction indication control signal, and process and obtain the directional traffic direction indication symbol 333. The yellow sign light 311, 321 that controls the traffic lights 31, 32 in advance to display the traffic direction indicator 330 and the steering respectively when the emergency vehicle 800 is about to reach the intersection area 700 The pass direction indicator 333 can be used by the passerby according to the pass direction indicator 330 displayed by the first traffic light device 31 at the intersection 701, or the afterward direction indicator 333 displayed by the second traffic light device 32. It is clear that the relative traffic direction of the emergency vehicle 800 when passing through the intersection area 700 can be clearly determined whether it is necessary to take a courtesy action or how to polite.

Further, the design of the turn determining unit 43 and the remote control unit 44 of the remote control host 4 can further cooperate with the design of the remote control unit 44 to determine that the emergency vehicle 800 intends to change the traffic direction when the intersection area 700 is about to pass. The traffic direction indication control signal after the change of the traffic direction is sent, and the traffic light direction indicators 330 and 32 of the corresponding traffic light device 3 are controlled to change the displayed traffic direction indication symbol 330 and the afterward traffic direction indication symbol 333, and After the emergency vehicle 800 passes through the intersection area 700, it is re-planned to generate a new navigation route.

Therefore, the present invention for the emergency vehicle 800 control system can correctly predict the emergency vehicle 800 to the passerby at the intersection 701 through the corresponding traffic light device 3 when the emergency vehicle 800 wants to pass through an intersection area 700. The direction of travel, which helps to reduce the incidence of traffic accidents at emergency intersection 800 at intersection 701, is a way to predict the direction of passage of the emergency vehicle without affecting the existing traffic indications of the traffic lights 31, 32 The innovative design of the function can indeed achieve the purpose of this new type.

However, the above is only the embodiment of the present invention. When the scope of the novel implementation cannot be limited thereto, all simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
