Example (b):
in order to construct a roadside system for prompting passing vehicles when pedestrians cross a street, firstly point positions are set: the pedestrian detection triggering unit is provided with: a roadside system for prompting passing vehicles when pedestrians cross a street mainly detects the existence information of the pedestrians crossing the street based on a radar-vision fusion all-in-one machine, and realizes the popup and screen-up of early warning information by adopting an LORA communication mode to achieve the purpose of reminding the passing vehicles to avoid the pedestrians, so that a pedestrian detection trigger unit is generally deployed in the areas such as crossing road sections where the pedestrians are easy to appear and disappear and have no lamp control and poor lighting environment, the detection range of a single radar-vision fusion all-in-one machine is 40-70 meters in the longitudinal direction and 30 meters in the transverse direction, so that for roads with the width of 70 meters, a set of pedestrian detection trigger unit is deployed on any side of the road, for the roads with the width of more than 70 meters, a set of pedestrian detection trigger unit is deployed on each side of the road, the height of the pedestrian detection trigger unit is about 3.5 meters, and the full coverage of the pedestrian crossing street areas is realized; LED hi-lite sign point location sets up: the core component equipment of vehicle early warning suggestion unit is LED hi-lite sign, and 2 sets are respectively installed at zebra stripes both sides to the sign, and every set contains initiative luminous comity pedestrian sign one, and initiative luminous pedestrian warns sign one, and wherein initiative luminous comity pedestrian sign installation is close to zebra stripes in principle, and initiative luminous pedestrian warns sign mounted position is apart from zebra stripes 50-80 meters. So as to reserve sufficient braking reaction time for the vehicle to pass through the detection area and prevent accidents. And then, completing a data link to realize data transmission: a roadside system for prompting passing vehicles when pedestrians cross a street uses a radar-vision integration all-in-one machine as core equipment to construct two different communication links: the first link takes a RS422 control interface of the radar-vision integration all-in-one machine as a data output interface, is connected with a logic controller, an LORA transmitting terminal, an LORA receiving terminal, a control panel, a high-brightness lamp board and an LED high-brightness indicating board, and adopts a serial port transparent transmission protocol and an LORA wireless communication protocol to realize the transmission of early warning signals; and in the second link, a RJ45 network port of the radar and video integration all-in-one machine is used as a data output interface, the RSU is connected through a network cable, and the transmission of target existing data (direction, speed, position and the like) and statistical data (the number of passengers, average speed and the like) is realized by adopting a TCP/IP protocol. Finally, the system function is verified through actual test: when a pedestrian, a non-motor vehicle and other targets pass through a detection area, the radar-vision integration all-in-one machine can detect information such as real-time speed, position and moving direction of a traffic target and continuously generate an early warning signal to be sent to the logic controller, after the logic controller receives the early warning signal, corresponding logic control information is generated according to the content of the early warning signal, a LORA sending end transmits the logic control information to a related LORA receiving end, and meanwhile, target existing data and statistical data collected by the radar-vision integration all-in-one machine are sent to a road side unit RSU through a network port; after receiving the logic control information, the LORA receiving end transmits a signal to the control panel, and the control panel makes corresponding signal feedback by judging the logic control information, so that the LED high-brightness indicator is linked to pop up preset early warning text information and control the lamp indicator to keep flashing or normally bright in a certain period; when the RSU receives effective data, the data are respectively sent to the cloud platform and the vehicle-mounted OBU, and the cloud platform and the vehicle-mounted OBU can receive and prompt early warning information which is the same as the roadside facility in real time; after the pedestrian passes through, when the thunder look fuses the all-in-one and detects out no target object in the detection area, no longer generate early warning signal, logic controller can not receive early warning signal just also no longer generate corresponding logic control information, also can not send logic control information again by the LORA sending terminal, and high bright lamp tablet and LED hi-lite sign resume acquiescence state, and RSU also can not send early warning information to OBU and cloud platform.
