Description
Technical field
The present invention relates to a kind of anti-lightning strike tunnel ponding warning system and method based on 4G network.
Background technique
With the development of the social economy, the improvement of people's living standards, the citizen for buying private car are more and more, in city
Also a large amount of Interchanges in Cities bridges and under-traverse tunnel have been built.In recent years, urban waterlogging phenomenon growed in intensity, and under-traverse tunnel is low
Depression just has a large amount of ponding.These ponding not only may cause vehicle stall, traffic jam, it could even be possible to the life to citizen
Life property safety causes to seriously endanger, and in order to solve this problem, people have invented miscellaneous tunnel water level monitoring system.
Existing some tunnel water level monitoring systems, have water level detecting and display capabilities mostly, can enter and leave in tunnel
Current ponding situation in tunnel is shown at mouthful, to prompt pedestrian and vehicle to enter with caution.Nonetheless, these current systems remain unchanged
There are many defects: can not achieve data sharing substantially, the ponding data in certain tunnel can only be used for their own, can not upload best friend
Logical commander's unit, therefore the local vehicle flowrate near the tunnel can only be adjusted；If meeting with rainstorm weather, system has can
Lightning stroke can be met with and paralysed, its effect can not be played.
Summary of the invention
It can not achieve monitoring data the purpose of the present invention is to solve existing tunnel water level monitoring system to share, occur
When ponding can only local directed complete set the problem of, and propose a kind of anti-lightning strike tunnel ponding warning system and method based on 4G network.
A kind of anti-lightning strike tunnel ponding warning system based on 4G network, composition include information processing transmission unit, water
Position detection unit, alarm unit, commander's unit, lightning-arrest unit and power supply unit, information processing transmission unit and water level detecting list
By power supply and information transmission yarn transmitted in both directions between member, transmitted in both directions between information processing transmission unit and alarm unit,
It is transmitted between information processing transmission unit and commander's unit by 4G network bi-directional；On information processing transmission unit and power supply unit
Lightning-arrest unit is installed respectively, water level sensing unit, information processing transmission unit, alarm unit and lightning-arrest unit all with power supply unit
Connection.
A kind of anti-lightning strike tunnel ponding alarming method for power based on 4G network,

Unit detects the water level information of installation site, and the micro energy lose detection module inside water level sensing unit is in running order, liquid level
Sensor and underwater electrical connector are in power-down state；
Step 2: water level sensing unit is still within working condition, micro energy lose detection module powers on liquid level sensor, liquid
Level sensor carry out height of water level detection, if water level is not detected as a result, if power off wait t1Repeat to power on after time, water level it is high
Detection operation is spent, water level sensing unit is transferred to working condition after detecting the value of height of water level；
Step 3: water level sensing unit is in running order, with time interval t2For the period, water level sensing unit detects water
Position elevation information；Wherein, t1>t2；
Step 4: being sent to information processing transmission unit after the height of water level information that water level sensing unit will test
Message processing module is encoded, and is uploaded to transmitting-receiving delivery module later, and transmitting-receiving delivery module storage height of water level information is simultaneously led to
It crosses 4G network and forwards it to commander's unit；
Step 5: commander's unit provides processing information after being connected to height of water level information, processing information descends into information processing
The transmitting-receiving delivery module of transmission unit, transmitting-receiving delivery module are sent to message processing module and are decoded, then can just send to
Water level sensing unit；
Step 6: water level sensing unit return step one.
The invention has the benefit that
Water level sensing unit is installed on minimum depression in tunnel by the present invention, and it is logical that alarm unit is installed on the disengaging of tunnel two sides
Road most full position, power supply unit are installed on the best position of tunnel upper daylighting, and information processing and transmission device are installed on tunnel

Information encoding-decoding and information storage function are carried out with message processing module, when water level detecting module reports information, must be carried out herein
It can just be uploaded to transmitting-receiving delivery module after coding, and then data are sent to commander's unit；The information that commander's unit passes down is through receiving and dispatching
It after delivery module, is decoded at message processing module, then can just send water level sensing unit to.Message processing module tool
Data can be carried out roller storage by the standby ability that data storage is carried out to two-way information, under normal operating conditions, be added up
Longest stored the period to 1 year.
Under the protection of lightning arrester, system can be measured and be stored to the depth of accumulated water in tunnel, and tunnel
Whether interior ponding situation passes through the electronic display and warning lamp real-time display of inlet, remind driver can be smooth in time
Pass through tunnel.At the same time, data can also be uploaded to remote command center by 4G network by the present invention, convenient for command centre into
The related scheduling of row, the vehicle flowrate in each tunnel is passed through in adjustment, and then largely alleviates traffic pressure.
