Embodiment Construction

[0024] Concrete structure of the present invention sees figure 1 , 2 shown.

[0025] The present invention includes two split devices. The reason for using the split device is that the OBD is mostly located under the main cab of the vehicle, but the main data measured is the light intensity value. If the split design is not adopted, the light intensity value should also be set at Under the main cab, if the ambient light is blocked, the measurement effect will be affected. Therefore, a split design is adopted, and the two split devices are connected through a wireless data transmission module (nRF24L01).

[0026] Split device one:

[0027] Split device 1 includes OBD module and wireless data transmission transmission module. The data control system uses the arduino UNO development board with ATmega328P as the main control chip.

[0028] 1. The OBD module is responsible for road mileage collection. This module collects the real-time speed of the vehicle through the vehicle O...

Abstract

The invention discloses an OBD-based light intensity measurement system in a vehicle-mounted tunnel, which includes two split devices connected through a wireless data transmission module; the first split device includes: an OBD module and a wireless data transmission transmitting module, data Control system; split device 2 includes light intensity acquisition module, wireless data transmission receiving module, SD card data storage module and data control system; the present invention can solve the problem of using OBD system to calculate displacement and light intensity acquisition technology to form a measurement device, Obtain the light intensity value in the tunnel according to the mileage, and use the relationship between the light intensity and the position to measure the technical problem of whether the tunnel design and traffic operation meet the driving requirements.

Description

technical field [0001] The invention relates to the technical field of traffic facility measurement and design; in particular, it relates to the illumination measurement technology of tunnels. Background technique [0002] At present, GPS is widely used in combination with various sensors, but if it is in a tunnel or when the GPS signal cannot be used, an alternative device is needed to replace the function of GPS. [0003] The traditional combination of GPS and light intensity acquisition technology forms a measuring device to measure whether the tunnel design and traffic operation meet the driving requirements, so as to ensure driving safety. When obtaining the light intensity value in the tunnel, because there is no GPS signal, the light intensity cannot be positioned, so the measurement purpose of obtaining the light intensity value in the tunnel based on the mileage cannot be realized. Contents of the invention [0004] The object of the present invention is to provi...
