Abstract
The invention relates to an optical fiber-based manhole cover weight measurement system. The optical fiber-based manhole cover weight measurement system comprises a manhole cover and a monitoring center. The optical fiber-based manhole cover weight measurement system is characterized in that the optical fiber-based manhole cover weight measurement system further comprises a human-computer interface, a processor, an amplifier, an APD detector and an optical wavelength division multiplexer which are arranged in the monitoring center, as well as a plurality of optical fiber weight measuring sensors arranged on the manhole cover, wherein the optical wavelength division multiplexer is connected with the plurality of optical fiber weight measuring sensors through optical fibers, the optical wavelength division multiplexer is connected with the APD detector, the APD detector is connected with the amplifier, the amplifier is connected with the processor, and the processor is connected with the human-computer interface. With the optical fiber-based manhole cover weight measurement system of the invention adopted, whether the manhole cover is damaged due to overweight can be judged, and maintenance and replacement costs of manufacturers can be decreased, and adverse effects caused by misjudgment of quality problems can be decreased. According to the optical fiber-based manhole cover weight measurement system, the optical fibers are adopted as the weight measuring components and signal transmission components, and therefore, field power supply is not required, and the system will not be subjected to electromagnetic interference and lightning damage. The system has the advantages of intrinsic safety, explosion-proof and insulation performance and lower cost.
Description
Technical field
The present invention 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.
Summary of the invention
Not enough for above-mentioned prior art, the invention provides a kind of energy and measure and record the well lid check weighing system based on optical fiber of well lid load-bearing.
Well lid check weighing system based on optical fiber provided by the invention 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 invention has the beneficial effects as follows:
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 invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
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 present invention 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 embodiments of the present invention, and it describes comparatively concrete and detailed, but can not be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to scope.
