Real time traffic parameter collecting device based on Bluetooth and coil technology

Abstract

The invention provides a real time traffic parameter collecting device based on Bluetooth and coil technology. The device includes a core processor, a data storage and transmission unit and a power supply unit. The sensor unit includes a Bluetooth processing module, a Bluetooth antenna, a GPS module, a GPS antenna, a coil processing module and a coil. The core processor is used for performing local storage and outward transmission on vehicle Bluetooth information, GPS positioning information and electronic pulse signals through the data storage and transmission unit. The power supply unit is used for supplying power. According to the invention, the device is mainly used for collecting and acquiring travel time, average speed and traffic flow of vehicles in a specific road range. Problems that a prior detection device cannot collect data in real time, is susceptible to weather and poor in adaptability are solved.

Description

technical field [0001] The invention belongs to the field of traffic information collection and analysis, and relates to a real-time traffic parameter collection device based on bluetooth and coil technology, in particular to a vehicle detection, road section vehicle travel time, road section vehicle average speed, and road section traffic flow based on bluetooth and coil technology Real-time collection equipment for traffic parameters. Background technique [0002] With the rapid development of the national economy and the acceleration of urbanization, the number of motor vehicles and road traffic in my country have increased rapidly. Especially in Beijing, Shanghai, Guangzhou, Shenzhen and other big cities, serious traffic congestion, increased traffic accidents, serious environmental pollution and other traffic environmental problems are extremely serious practical problems facing the development of cities in our country. The general solution to traffic problems is to fi...

AI Technical Summary

Problems solved by technology

The general solution to traffic problems is to find ways to build more roads, but with limited urban land resources, there is less and less room for new roads

The traffic information collection technology based on mobile communication is to use mobile phone positioning to calculate the traffic flow status, so as to obtain the corresponding traffic information. Its advantages are wide coverage, large sample size, and relatively low cost. Applicability and other aspects need to be studied

[0004]The existing Bluetooth technology cannot obtain the traffic flow of the road section; the existing Bluetooth technology does not have a GPS positioning system, and cannot efficiently determine the specific location of the device; the existing Bluetooth technology does not have a GSM module and a WIFI module, so it cannot transmit data wirelessly, so it cannot obtain traffic parameters in real time; the existing Bluetooth technology does not have a power plug, and it cannot effectively use the power supply for power supply under certain specific conditions, and there is a problem of power failure. Possibility; the existing coil technology can obtain the traffic flow parameters of the road section, but cannot efficiently and conveniently obtain the travel time of the road section vehicles and the average speed of the road section vehicles
