Abstract
The utility model relates to a well lid check weighing system based on optic fibre, including well lid, surveillance center, its characterized in that: still wrap the man -machine interface, treater, amplifier, APD detector, light wavelength division multiplexer and the optic fibre check weighing sensor of a plurality of setting on the well lid that set up in the surveillance center, adopt between light wavelength division multiplexer and a plurality of optic fibre check weighing sensor the fiber connection, light wavelength division multiplexer connects the APD detector, the amplifier is connected to the APD detector, amplifier connect the processor, man -machine interface is connected to the treater. The beneficial effects of the utility model are that: can judge whether the well lid damages because the bearing exceeds standard, reduce the maintenance and the replacement cost of living firm, reduce the harmful effects because of thinking that quality problems bring by mistake, the check weighing component and the signal transmission of this system are optic fibre, and the scene need not supply power, not damaged by electromagnetic interference and thunderbolt, intrinsic safety, and insulating explosion -proof, the cost is lower.
Description
Technical field
The utility model relates to a kind of inspection well cover, specifically a kind of well lid check weighing system based on optical fiber.
Background technology
A lot of underground pipeline is had in urban construction, such as sewer, underground gas pipeline, water supply pipe, power pipe, communication conduit, national defence pipeline etc., these pipelines will have an outlet of leading to ground every one section, inspection shaft is called to this section on ground by pipeline, catch pit port is usually concordant with ground, therefore need a lid, be used for the lid of lid inspection shaft, be inspection well cover.Inspection well cover is made with materials such as reinforced concrete, metal, reinforced plasticss usually, and shape is based on circular and square.There are many superimposed trucks can press through well lid in motion at present, cause well lid to be damaged.But the user of well lid can think that well lid is defective in quality, manufacturer is directly looked for keep in repair or change well lid, because manufacturer cannot prove because load-bearing exceeds standard and damages, so can only according to user's requirement, repair or replace well lid, bring massive losses and harmful effect to manufacturer.So need a kind of well lid check weighing system based on optical fiber measuring well lid load-bearing badly.
Utility model content
Not enough for above-mentioned prior art, the utility model provides a kind of energy measure and record the well lid check weighing system based on optical fiber of well lid load-bearing.
The well lid check weighing system based on optical fiber that the utility model provides is achieved through the following technical solutions:
A kind of well lid check weighing system based on optical fiber, comprise well lid, Surveillance center, it is characterized in that: also wrap the man-machine interface, processor, amplifier, APD detector, light wavelength division multiplexing and the multiple optical fiber load cell be arranged on well lid that are arranged on Surveillance center, described Fiber connection is adopted between described light wavelength division multiplexing and multiple optical fiber load cell, described light wavelength division multiplexing connects APD detector, described APD detector connects amplifier, described amplifier connection handling device, described processor connects man-machine interface.
Described processor is super high-speed A/D Acquisition Processor.
The beneficial effects of the utility model are:
1, well lid can be recorded by each load-bearing data after pressing, after well lid damages, analyzed by called data, can judge whether well lid damages because load-bearing exceeds standard, reducing maintenance and the replacement cost of raw manufacturer, decreasing the harmful effect brought because thinking quality problems by mistake;
2, the check weighing element of native system and Signal transmissions are optical fiber, and scene does not need power supply, and not by electromagnetic interference (EMI) and broken by lightning, intrinsic safety, insulation explosion-proof, cost is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of well lid check weighing system based on optical fiber as shown in Figure 1, comprise well lid, Surveillance center, it is characterized in that: also wrap the man-machine interface, processor, amplifier, APD detector, light wavelength division multiplexing and the multiple optical fiber load cell be arranged on well lid that are arranged on Surveillance center, described Fiber connection is adopted between described light wavelength division multiplexing and multiple optical fiber load cell, described light wavelength division multiplexing connects APD detector, described APD detector connects amplifier, described amplifier connection handling device, described processor connects man-machine interface.
Further, described processor is super high-speed A/D Acquisition Processor.
The utility model can the multiple well lid of real time record by each load-bearing data after pressing, and send data to man-machine interface and carry out record feedback, after well lid damages, analyzed by called data, can judge whether well lid damages because load-bearing exceeds standard.
The above embodiment only represents embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to the utility model protection domain.
