Background technique
If damaged inspection well cover cannot be replaced in time, the safety of pedestrian and vehicle can be endangered, when serious even
People's life can be jeopardized；And in the management of the inspection well cover of substantial amounts, the well lid bring harm of badly broken is more more than breakage
Slight well lid.So all damaged inspection well covers are carried out priority queueing according to damaged degree difference, then from most serious
Inspection well cover repairs, and can reduce the various safety accidents of inspection well cover breakage initiation to greatest extent, realizes intelligent, fine
The inspection well cover management of change.
Existing technology is mainly segmented into two major classes to the detection of inspection well cover breakage.One kind is using the special of redesign
With inspection well cover, such as: CN 106841327 A of 105201014 A and CN is circled round by latticed, wave preset inside well lid
The wire or metallic film of shape are as breakage sensor.After manhole cover damage, the metallic film or metal of corresponding position
Silk will be broken therewith, pass through the presence or absence of external interface voltage in this way it is determined that well lid whether there is or not breakages.But exists and need
It goes to replace existing well lid using dedicated well lid, the shortcomings that well lid being replaced will cause the wasting of resources.And inspection well cover
Overlapping investment improves engineering cost.
Another kind of is to carry out damage testing to well lid by adding sensor in well lid bottom surface, such as: 206440654 U of CN
It has used parallel metallic film item to be attached to well lid bottom surface, has then been judged with the on-off of the method for digital circuit detection metal strip
Whether there is or not breakages for inspection well cover.Well lid bottom surface is pasted onto using conductive film item in 206440654 U of CN and constitutes manhole cover damage detection
Sensor.But this is just needed there is also every more films plus a detection circuit, the problem of promoting circuit complexity.And
Detection circuit and colorimetric sensor films are alived always, and the energy of power supply is consumed, and are unfavorable for promoting battery power supply class detection system
Stand-by time.Breakage for being parallel to detection film cannot detect well.
The common drawback of the above two classes technology be can only distinguish well lid be it is damaged or intact, cannot detect well lid
Damaged degree.

It send after capable of reflecting the low level quantity to server end of the detector output end mouth of the damaged degree of inspection well cover, server inspection well cover
Management system can be tieed up from service worker's distance locatingly according to the damaged degree of inspection well cover, the traffic flow size on locating ground
Repair management.Using the utility model can with least investment, realize inspection well cover maintenance fine-grained management, utmostly prevent because
Manhole cover damage and caused by person property loss.Specific manifestation is as follows:
1. the Concentric circles detection sensor being made of conducting wire, structure is simple, low in cost, it is easy to accomplish, detection circuit letter
List is reliable, low-power consumption, can detect manhole cover damage degree.
2. being advantageously implemented and being broken to well lid implementation selectivity by the flexible control to the concentric radius of circle of detection sensor
Damage detection.
3. the sensitivity and accuracy of detection device can be increased by the quantity for increasing detection concentric circles, it is more advantageous to clothes
Device end inspection well cover management system of being engaged in carries out the priority queueing of damaged degree to inspection well cover to be repaired.
4. avoiding detection circuit according to the breakage of time interval query formulation detection inspection well cover and being in energization for a long time
State is preferably minimized the power loss of detection circuit.
5. being based on inspection well cover damaged degree, the traffic flow size of inspection well cover present position and inspection well cover present position are from maintenance
The fine-grained management of the far and near inspection well cover maintenance realized of worker, greatly reduces and causes person property since inspection well cover is damaged
A possibility that loss.
