Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] figure 1 It is an overall structural diagram of a safe vehicle speed prompt and alarm system of the present invention, such as figure 1 As shown, MSP430 is used as the main processing platform to convert the photometric signal collected by the illuminance sensor inside and outside the tunnel into a digital signal, and the conversion result of ADC12 is stored in the specified array, and the voltage difference corresponding to the illuminance is calculated, and the difference between the illuminance difference and the safe vehicle speed is used. Relational formula to calculate the safe vehicle speed.

[0047] The formula is as follows:

[0048] speed (safe vehicle speed) = 120-40*sum (voltage difference corresponding to illuminance difference)

[0049] The host computer data transmission and monitoring and alarm functions are realized through wireless transmi...

Abstract

The invention discloses a safety driving speed prompting monitoring alarming system. The safety driving speed prompting monitoring alarming system comprises an illuminance signal acquisition and conversion circuit for detecting light intensity, a clock circuit for providing clock signals and realizing time calculation and display, a key circuit for manually setting a current safety driving speed,a power circuit for providing normal voltage for the normal operation of the whole circuit, a display circuit for displaying the safety driving speed and time, a system main control module which collects the information to send a control command to a system terminal and wirelessly transmits the result to an upper computer for monitoring, a speed measuring module which monitors the real-time speedof a vehicle, a wireless transmission module which uploads the vehicle speed data collected by the speed measuring module to the upper computer for monitoring in real time and an alarm module which receives the uploaded vehicle speed data, compares the speed data with the speed limit of the relevant road section prescribed by the national law, sends the information to the system terminal, that is,a controlled device and issues alarm. The safety driving speed prompting monitoring alarming system has the characteristics that the safety driving speed can be intelligently prompted, and the driving is enabled to be more safe and convenient.

Description

technical field [0001] The invention relates to the technical field of safety speed prompt and alarm, in particular to a safety speed prompt monitoring and alarm system. Background technique [0002] With the widespread adoption of long tunnels, tunnel safety issues have become increasingly prominent. Tunnels are road sections with special operating environments in the road system, which have an important impact on driving safety. Tunnel entrances and exits are transitional sections between two different operating environments, and often become tunnel accidents. concentration point. One of the main reasons is that the driver's vision at the tunnel entrance and exit has the problem of light and dark adaptation. During the day, when a car approaches a tunnel entrance where the illumination brightness is much lower than that of the external environment, because the human eye has no time to adapt to the sudden change of light, there will be a feeling like a black cave at the en...
