Description
Technical field
The utility model relates to road safety monitoring technical fields, and in particular to a kind of road ponding automatic monitoring system.
Background technique
So far from the eighties of last century the eighties middle period, experienced close to 40 years development and continuously improve, China is in water
Feelings complete from scratch in terms of being monitored automatically with early warning system, and experienced high-speed development period and widely popularize using the phase, and
Achieve numerous achievements attracted attention.But because starting late, advanced technology falls behind relatively, and the regimen in China monitors automatically is
System is compared with developed countries there are also huge spread and many shortcomings, and gap and deficiency are mainly reflected in: extensive collection
At the undeveloped of circuit engineering, thus the regimen in China monitor automatically it is succinct not enough with the hardware components of early warning system, and can
It can't be ensured well by property；Regimen monitors and the precipitation rain fall sensor that uses in early warning system and level sensor automatically
Device type is single, and sensor function is incomplete, and more demanding to use environment；Communication mode is incomplete, sets up communication
Many communication blind spots etc. can be encountered when network.
Water on urban streets automatic monitoring system hardware design in the prior art is primarily present following technological deficiency: (1)
