Description
Technical field
The present invention relates to a kind of bushing type underground installation wireless transmission automatic early-warning system, for realizing automatic early-warning under underground installation leakage situation, and providing underground installation for information about.
Background technique
Along with the progress of society and the development of national economy, the technical requirements of people to infrastructure is more and more higher, country is also increasing to the input of infrastructure, the underground installations such as pipeline, electric wire and communication optical cable such as the water supporting with it, electricity, warm, combustion gas are also increasing thereupon, it has been the important component part of people's daily life, work interwoveness, and it is all relevant with underground installation that red cent is often thrown in infrastructure.For this reason; to the appropriate design of underground installation, three-dimensional planning, safety protection, especially after rationally laying; how when no-dig technique to the underground installation of complexity carry out " transparent " and " visual " management, can automatic early-warning when emitting leakage and breakage to underground installation, this just needs many-sided and multidirectional technological scheme and technical support.
For preventing again damaging underground installation in process of construction, on November 25th, 2004, the applicant has applied for that Authorization Notice No. is the utility model patent " mark band for underground installation " of CN2745074Y, when excavator excavates underground, the underground installation whereabouts indicating strip folded part be embedded between shallow surface and embedded object can with excavator bucket passive open.Can according to the relevant information handled of the underground installation that mark band marks after builder finds, therefore underground installation can be protected, and can not cause economic loss because digging bad underground utility, ensure that people produce, normally carrying out of living.But, this underground installation whereabouts mark band can only show the alarming sign with underground installation herein when being about to dig underground installation, cannot the specifying information of embedded object be identified as buried time, the degree of depth, the concrete shape of cross pipe-line or the type Use etc. of underground installation underground and be located, transparent, " visual " ground intelligent menagement can not be realized.For head it off, on April 18th, 2012, the applicant has applied for that publication number is the patent of invention " underground installation identity device " of 102707335A, comprise and be layed in mark band between underground installation top and earth's surface and chip assembly, chip in chip assembly can store the various data that specification has intercommunity, as buried the information of ditch underground; The information of underground installation self; Distance between time of burying underground of underground installation, the depth of burying, pipeline and position, concrete crossing instances etc., and realize the identification to underground installation by sniffer, exchange with computer network presenting information and share, to reach the transparent management to underground installation.But in application process, find that this technology also has the following disadvantages:
1. underground installation due to quality of product, laying technology, naturally damaged and personal factor cause leak, leak gas, leakage of oil, the situation such as electric leakage, every day, this device can not emit leakage to carry out automatic early-warning period embedded object is elementary all in generation in various degree.
2. wherein chip assembly by the direct fixed placement of chip assembly bag on mark band, when chip assembly break down need change time, must be excavated at fault nidus and be dragged to ground and change, bring inconvenience to construction and site traffic, people's life etc.The precondition setting up automatic early-warning system is active, if be embedded in underground early warning with active chip, once power depletion Switching power becomes a difficult problem.
3. the precondition setting up automatic early-warning system is active, if be embedded in underground early warning with active chip, once power depletion Switching power becomes a difficult problem.
4. the core of automatic early-warning system is sensor, at present, to underground installation transport materials sensor recognition technology on the ground, the effective age of automatic early-warning can be reached also only at 2-3, if be positioned over underground, it is moistureproof, corrosion-resistant management difficulty will strengthen, effective recognition time of sensor can be shorter, and this brings great difficulty to switch operating again.
