Embodiment Construction

[0024] like figure 1 As shown, the Bluetooth-based traffic flow detection device is characterized in that it consists of a dispatch center, a base station, an electronic stop sign, a vehicle-mounted Bluetooth module, and a station bluetooth module. The electronic stop sign also includes an LCD display module, a button module and a data processing module. . Through the connection and pairing of the master and slave Bluetooth devices, if the controller detects a level jump, the counter starts counting and displays the traffic flow through the display module.

[0025] The controller is composed of central processing unit CPU, program memory, data memory, interrupt timer, etc., and is used for the control of the whole device and data signal processing.

[0026] The on-board Bluetooth module is a slave device, and the current state of the module can be judged from the blinking of the indicator light of the module, whether it is a slave or a master. The on-board Bluetooth module i...

Abstract

The invention relates to a Bluetooth-based traffic flow detection device and an implementation method. The device comprises a scheduling center and n base stations, a traffic region needing to be detected is partitioned into n sub-regions, one base station is arranged in each sub-region, and electronic station boards are arranged on bus stops in the sub-regions. The method comprises the following steps: communicating with a vehicle-mounted Bluetooth unit in a Bluetooth wireless way; acquiring traffic flow information; periodically uploading traffic flow information to the base stations; periodically uploading to the scheduling center through the base stations. By adopting the device and the method, a user can know the traffic flow situation of each road segment conveniently whenever and wherever possible, and urban vehicle traffic running states are provided for travelers and drivers. Moreover, a Bluetooth technology plays an important role in a system. By adopting the Bluetooth technology, real-time data acquisition, high-speed information exchange and flexible networking in the system are realized, and the device is easier and more convenient to implement.

Description

technical field [0001] The invention belongs to a traffic flow detection device and method, in particular to a traffic flow detection device and a realization method combining bluetooth and a controller. Background technique [0002] With the development of economy, the process of urbanization in our country is constantly accelerating. Due to the increase in the number and scale of cities, the number of urban motor vehicles also increases sharply, and the traffic pressure continues to increase. The increase in the number of cars has caused the deterioration of traffic conditions. On the one hand, traffic jams and other phenomena are serious. On the other hand, the incidence of traffic accidents has increased, leading to a series of problems such as life safety and property loss. According to Zhang Guochu, Institute of Quantitative Economics and Technical Economics, Chinese Academy of Social Sciences, traffic jams waste transportation resources in Beijing and reduce transport...
