Embodiment 1

[0044] From 18:05:00 to 18:55:00, measure the current road condition information at an intersection or at an appropriate location on the road.

[0045] 1. Turn on the mobile power supply, and the Bluetooth monitoring terminal will start working;

[0046] 2. Place the Bluetooth monitoring terminal at an appropriate position at the intersection or on the road (the Bluetooth monitoring terminal needs to be placed in pairs, and each pair of Bluetooth monitoring terminals feedbacks the traffic status of the covered road)

[0047] 3. Observe whether the monitoring terminal is working normally, including whether it is searching normally, whether it is connected to the central computer, whether it is sending data in real time, whether the timing is accurate, etc.; if there is a problem, restart the Bluetooth monitoring terminal;

[0048] 4. If the terminal is working normally, close the cover of the test chamber and leave the site; in this state, each terminal will send the collected ...

Abstract

The invention discloses a bluetooth-based real-time feedback system and method for road traffic status in large cities. There are omnidirectional antennas extending out of the housing. Obtain the MAC address of cross-border bluetooth device by bluetooth module and send to remote computer by GPRS module after time matching by ARM single-chip microcomputer, can draw average passing time by remote computer, thereby draw current road condition information, the present invention adopts modular design, each part The function division is clear and the connection is reasonable; and each component has a finished product that can be used, no need to design an integrated circuit by itself, which is convenient for assembly and production; in addition, the entire terminal is based on the single-chip development board, and the debugging of programs and instructions can be conveniently carried out in the computer , which reduces the cost of the road state feedback work and improves the flexibility of the feedback equipment.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a bluetooth-based real-time feedback system and method for road traffic status in large cities. Background technique [0002] The automatic license plate recognition technology has the advantages of high degree of automation, high recognition rate, and wide range of applications; however, due to its own complexity, the automatic license plate recognition technology is easily affected by environmental factors such as weather and light, and has poor environmental adaptability. It is not conducive to the further promotion and use of automatic license plate recognition technology. In addition, the traditional automatic license plate recognition technology has high cost and poor application flexibility. If it is only used for real-time feedback of road traffic information, it will cause waste of resources. At the same time, the automatic license plate r...
