FIG. 1 is a schematic diagram of an embodiment of an intelligent traffic indicating system of the present invention.
Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1, a schematic diagram of an embodiment of an intelligent traffic indicating system of the present invention is shown. In the present embodiment, the intelligent traffic instruction system includes a mobile terminal 3, a cloud server 2, and a local processing device 1. The mobile terminal 3 may be any one of a mobile phone, a smart watch, a tablet computer, or other devices.
The local processing device 1 is arranged at each traffic signal to be indicated when in use, and comprises a time display lamp set 11, a camera 12, a main control unit 13, a remote communication unit 14 and a local communication unit 15. The time display lamp group 11 can be for example liquid crystal display, LED display screen etc. camera 12 can adopt the camera of fixed angle, also can adopt the cloud platform camera, and main control unit 13 can adopt based on arbitrary one or more in FPGA, singlechip etc. remote communication unit 14 can be any one in 3G, 4G, 5G module, and local communication unit 15 can be any one in bluetooth or the wifi module.
During installation, the camera 12 faces the color indicating lamp set to be displayed for the waiting time so as to shoot the color indicating lamp set to be displayed for the waiting time, and the color indicating lamp set can be a combination of a red lamp and a green lamp and can also be a combination of the red lamp, a yellow lamp and the green lamp. Since the color indicator light sets are generally paired to appear on both sides of the crossing, in another embodiment of the present invention, the camera 12 is a color indicator light set facing the color indicator light set to be displayed for the time, and the others are not changed. In this embodiment, the camera 12 captures image information of the color indicator light set at the position to be indicated of the traffic signal, and transmits the image information to the main control unit 13 connected thereto, and the main control unit 13 controls the remote communication unit 14 to transmit the image information to the cloud server 2. Each local processing apparatus 1 has a unique communication address, and the corresponding unique communication address of the image information when transmitted is also transmitted to the cloud server 2; therefore, the cloud server 2 can identify which local processing device 1 sends the information, and when the subsequent cloud server 2 sends data to the local processing device 1, the subsequent cloud server 2 can also perform corresponding transmission through the unique communication address, for example, the subsequent cloud server 2 sends the traffic indication time control signal to the corresponding local processing device 1 according to the unique communication address.
The cloud server 2 respectively performs image analysis on the received image information of each local processing device 1 to obtain an indication rule of a color indicator lamp group of each local processing device 1, respectively generates a traffic indication time control signal according to each indication rule, and then respectively sends the traffic indication time control signal to the corresponding local processing device 1; the main control unit is also used for controlling the time display lamp set to display the remaining duration of the lamp effect of the color indication lamp set according to the received traffic indication time control signal. The step of performing image analysis on the received image information of each local processing apparatus 1 specifically includes the following steps:
(1) Extracting an image of the traffic indicator light from the frame of the image information according to a preset traffic indicator light contour identification feature;
(2) Extracting color information of the traffic indicator lamp from the extracted image of the traffic indicator lamp;
(3) Judging the continuous frame number of each color in the color information;
(4) calculating the duration of each color in the color information, wherein the duration is calculated according to the following formula:
The duration is the duration frame number and the preset inter-frame interval duration.
Since the image processing is completed by the cloud server 2, the processing capacity requirement for the local processing device 1 is not high, so that the hardware cost of the local processing device 1 can be effectively reduced.
the image information includes time information of image capturing, and the traffic indication time control signal includes: the lighting sequence and the lighting duration of each color lamp in one working cycle of the color indicator lamp group, and the starting time displayed at this time of the time display lamp group and the remaining duration of the lamp effect corresponding to the starting time.
After receiving the traffic indication time control signal, the local processing device 1 may repeatedly indicate the time display lamp set according to the signal, so that it is not necessary to capture image information all the time and send the image information to the cloud server 2, and how to reduce the workload of the local server 1 and the cloud server 2, in this implementation, the traffic indication time control signal is sent to the corresponding local processing device 1 only within a preset time period, where the preset time period is 11:00-12 at noon of each day: 00 and 23:00-24: 00.
In another implementation of the present invention, the camera is further configured to capture, after the traffic indication time control signal starts to act, image information for verification of the color indication lamp set at the position to be indicated by the traffic signal and image information for verification of the light effect remaining duration of the time display lamp set at the position to be indicated by the traffic signal; the cloud server is further used for judging whether the indication states of the time display lamp group and the color indication lamp group are consistent or not according to the verification image information and the verification lamp effect remaining duration image information, and if not, the cloud server generates a new traffic indication time control signal according to the new image information to control the display content of the time display lamp group.
the local communication unit 15 is connected to the main control unit 13, and is configured to receive a control instruction sent by the mobile terminal 3 locally, and the main control unit 13 controls the time display lamp set to display the remaining duration of the lamp effect of the color indicator lamp set according to the control instruction and synchronously controls the color indicator lamp set to perform corresponding indication; when the control instruction is executed, the traffic indication time control signal is stopped to be executed. Because the rigid traffic indication rule can not effectively meet the complicated and changeable road conditions in many times, traffic commanders (traffic police) can send appropriate traffic command signals (control instructions) to the local processing device 1 through the mobile terminal 3, and the control instructions can control the color indicator lamp set to carry out corresponding instructions so as to better carry out traffic command according to local conditions.
The local communication unit 15 is further configured to forward the image information to the mobile terminal 3 and to the cloud server 2 via the mobile terminal 3 at the request of the mobile terminal 3, and is configured to receive the traffic indication time control signal forwarded via the mobile terminal 3. In this way, when communication between a certain local processing apparatus 1 and the cloud server 2 fails, data can be relayed by the mobile terminal 3, which is suitable for a case where the local processing apparatus 1 cannot be repaired in time.
it will be understood that the foregoing is only illustrative of the principles of the invention, and that no description of some common general knowledge in the field, such as sampling, encrypting, decrypting, decoding, etc., is given without departing from the spirit of the invention.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
