More specifically, the head-mounted intelligent traffic light system provided by the invention can be used in any occasions that no traffic signal light is arranged at the intersection or the original fixed traffic signal light breaks down and the traffic order needs to be maintained. The hardware main circuit of the head-mounted intelligent traffic light system is divided into: the device comprises an embedded system, a motor driving module, a gyroscope module, a Beidou positioning module, an LED traffic light display module, a portable power supply module, a wireless transceiving module, a key module and the like.
The head-mounted intelligent traffic light system has the following functions:
in consideration of the problem of long-term load of a user, the power supply is designed to be tied between the waist and connected with the head-mounted traffic light through the connecting wire. After the user wears the head-mounted traffic light and turns on the power switch, the traffic light can work circularly according to the preset time period. If the traffic flow of a certain direction is large, the user can increase the green light release time of the intersection through the wireless keys, and after the setting is good, the road in the direction can keep smooth due to the fact that the green light release time is prolonged. After a period of time, if the traffic flow in the other direction is larger, the user can immediately reduce the green light release time in the previous direction through the wireless key, and instead increase the green light release time in the previous direction, so that the intersection can continue to keep a smoother state. When the road conditions in all directions are almost the same, the user can adjust the passing time of the green light in all directions to the same time through the wireless keys, and the smooth intersection is kept.
Staff on duty, when they command traffic on the road, when the traffic flow is large, the passage of roads in several directions is controlled by them. They sometimes need to face intersections in one direction and sometimes turn around to face intersections in another direction by constantly changing directions to better maintain traffic order. If only simple design a fixed head-mounted intelligent traffic light, when they turned round, overhead traffic lights also followed the rotation, and original green light probably becomes red light or yellow light at once, perhaps red light becomes green light or yellow light, not only can cause the short confusion of traffic, also can bring traffic safety hidden danger. In consideration of the situation, when the system is designed, the traffic light is not simply installed on the traffic light, but is divided into an upper part and a lower part, the gyroscope module and the LED traffic light display module are placed on the upper layer, and the embedded system, the motor driving module, the positioning module and the wireless transceiver module are placed on the lower layer. After the operator starts the machine, a fixed direction is selected, and after a set key is pressed, the embedded system records the azimuth angle and the position of the current traffic light. When a user turns or walks, the embedded system can know that the coordinates of the traffic lights on the upper layer are changed through the gyroscope module and the GPS module, when the changed position exceeds the set value, the situation that the traffic lights deviate from the set direction is indicated, and the signal lights need to return in time to ensure the normal work of the signal lights. The embedded system can immediately send out a corresponding control signal to control the motor to rotate in time, so that the traffic light is always kept at the set coordinate position, and the condition of deviation cannot occur. Just because the system adopts such structure and control method, the traffic lights of all directions can all keep original state, for example in this direction, the road is green light now or green light originally, is red light now or red light originally, and the yellow light is also the yellow light, and the traffic signal lamp can not appear wrong demonstration, just can not make the traffic state that the confusion appears. The invention enables the staff to use the traffic signal lamp to help maintain the road smoothness and pay attention to the road state in each direction at any time when the staff is on duty.
And thirdly, in the system designed by the invention, the traffic light adopts an assembled structure. Except for being used on roads at three intersections, when the original traffic signal lamp at a certain intersection cannot continue to work due to various reasons, the system can be quickly assembled, the frequently adopted system with three signal lamps is changed into the system with four signal lamps, and the requirement of the intersection is met. Because the system adopts the structure of assembling, the staff can be when not needing to maintain traffic order, can tear down wear-type intelligent transportation lamp piecemeal, reduces entire system's volume, makes things convenient for the staff to carry, improves the portable performance of system greatly.
The system is also provided with a camera module, and when a worker commands traffic, if someone or a vehicle does not listen to the command and the worker must make a hard red light break, the worker can record the information of the person or the vehicle through the camera so as to carry out later processing. In addition, the camera module is added, and when disputes occur, the current conversations, actions and the like of the two parties can be recorded, so that reliable and powerful evidence is provided for legal and reasonable solution of the matters.
The system is also provided with an SIM card module, the system carries out data transmission with a traffic guidance center through the SIM card module, and the traffic guidance center can clearly know the position of corresponding staff through the built-in unique SIM card module of each intelligent traffic light system. When pedestrians and vehicles at the intersection are too many and a traffic worker is busy, the worker can immediately send a signal needing the control center and giving hands to support the control center to the control center through the keys. After the command center receives the signal, the command center can dispatch personnel immediately to drive the corresponding intersection, and the traffic order of the intersection is ensured to be in a controllable range.
The technical scheme provided by the invention is not limited to helmets, and can also be extended to wearing equipment such as clothes or backpacks.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents, improvements, etc. that are within the spirit and principle of the present invention should be included in the present invention.
