Embodiment Construction

[0010] The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

[0011] like figure 1 and figure 2 As shown, the urban intelligent traffic guidance screen includes a power supply module, an LED display module, an LED breakpoint detection module, an LED brightness detection module, a state temperature detection module, an on-site debugging interface, a control panel, a communication transmission module and a main control module. The power supply module may include a switching power supply, a power surge protector, and a power adapter board. The power supply is introduced from the external mains to the power surge protector. powered by. The power supply includes a power supply detection module, which can detect the working voltage of each power supply, detect abnormalities in time, and activate the backup power supply. The power surge protector has lightning protection detection, which can detect whether the lightning prot...

Abstract

The invention discloses an urban intelligent traffic guide display, which is characterized in that: a light-emitting diode (LED) display module is connected with a master control module; the LED display module is connected with an LED breakpoint detection module and a power supply detection module respectively; the LED breakpoint detection module, the power supply detection module and the state and temperature detection module are connected to the master control module via a RS485 bus; the master control module is connected with a RS485 signal lightning arrester which is connected with data lightware terminal equipment; the data lightware terminal equipment is connected with a personal computer (PC) via an optical fiber; the LED luminance detection module is connected with the master control model; an on-site debugging interface is connected with the master control module via a RS232; and the control penal is connected with the master control module. The urban intelligent traffic guide display has the functions of local / remote control, power supply detection, breakpoint detection, LED luminance adjustment detection, case state detection, case temperature detection, lightning protection and the like and has the advantages of simple and practical circuit design, low power consumption, stable working performance and the like.

Description

Technical field: [0001] The invention belongs to the technical field of urban road network traffic information, is a dynamic traffic guidance system device, and is an important part of an advanced traffic information service system and traffic management system, which is used to analyze dynamic traffic conditions and process them in real time to guide people Choose the right route to avoid traffic jams and improve road traffic efficiency. Background technique: [0002] At present, my country's economy is developing rapidly and sustainably, and the level of urban modernization is gradually improving. The number of automobiles has increased sharply, resulting in a large amount of road transportation demand. Traffic congestion and uneven distribution of traffic flow in the road network have become increasingly prominent. Pervasive problem. Due to the randomness and irregularity of traffic participation, traffic managers cannot plan in advance, thus aggravating the pressure of u...
