Description
Technical field
The utility model relates to pipeline network pick-up unit.
Background technology
Along with the development of urban construction, people have built a large amount of underground transfer tube gauzes.Now, the focus of transfer tube gauze just progressively by engineering construction to the maintenance management transition, integrate the comprehensive pipeline network detector tube reason device that detection, webmaster and literary composition retaining are managed but lack one.
Present pipe detection device has two kinds of schemes: (1) wired active type; (2) wireless active type.
Wired active type generally is made of supervising device, auxiliary monitoring device, Remote Power Supply, metal cable and active-code sensor.The wireless active type is compared with wired active type, has replaced wire transmission (but cable not necessarily reduces) with wireless signal on transmission mode.Because of the reason of electromagnetic interference (EMI), rate of false alarm is higher.These two kinds of technical schemes must adopt Remote Power Supply, and to the power supply of active-code sensor, therefore have following defective: (1) needs power supply; (2) complex structure: owing to sensor adopts active device, under the mal-condition of electronic component humidity in well, must adopt totally-enclosed moisture preventive measure, also will consider to bear the electromagnetic interference (EMI) of dealing automobile generation on the road surface and the influence of strenuous vibration.(3) production cost height: satisfy environmental requirement as much as possible for making sensor, it is very high that the production cost of sensor must become.(4) the daily servicing amount is big: must drop into great amount of manpower, and require to possess the maintainer of certain electronic technology.
Summary of the invention
The purpose of this utility model provides the intelligent pipeline network pick-up unit that a kind of working stability is reliable, I﹠M is convenient and swift, the ratio of performance to price is higher.
A kind of intelligent piping network monitoring device described in the utility model comprises Surveillance center's watch-dog, transmission line and the senser element that is coupling on the transmission medium.The NEW TYPE OF COMPOSITE optical cable that transmission line adopts tight tube fiber and rigidity cable to form, senser element and composite cable close-coupled are formed complete sensing device.
General optical fiber tensile strength is very low, frangibility, and moisture-sensitive is damaged, and can not use in this environment.For this reason, the inventor has designed a kind of special optical cable.It is a single fiber cable; The employing tight tube fiber increases by one and increases tensile strength and flexible rigidity cable (soften-referring to its bending easily, firm-refer to that it is difficult for stretching on length).And the cushion that forms the slip effect between cable core and oversheath, oversheath adopts material wear-resisting, anti-water to make.This optical cable has indispensable performances such as softness, tension, waterproof.
Composite cable described in the utility model can have two kinds of technical schemes:
I type composite cable:
Its skin is an oversheath, and tight tube fiber and rigidity cable are positioned at oversheath, also has cushion and inner waterproofing sheath between tight tube fiber and the oversheath.
II type composite cable:
Its skin is an oversheath, and internal layer is a cushion, and tight tube fiber and rigidity cable are positioned at cushion.
The utility model is applied to optical fiber technology in the detection system, makes optical fiber both as the transmission of Information medium, again as the ingredient of senser element.
Senser element described in the utility model can be divided into continuous type senser element and discrete type senser element two classes from the distribution of application point; From operating principle, can be divided into pressure-type senser element and thermosensitive type senser element two classes.The thermosensitive type senser element comprises memory metal heat sensitive sensor spare, fusible metal heat sensitive sensor spare.The application of these senser elements all be unable to do without the characteristic of optical fiber.Generally communicate by letter with optical cable or optical fiber, do not allow bending or pressurized, after optical cable or optical fiber pressurized or distortion, will make communication disruption, this is unallowed.We are by senser element, have a mind to cause the deformation of optical fiber.The pressure that senser element is experienced changes or temperature variation, and the local bending that all converts optical fiber to changes, and causes the luminous power or the catoptrical variation of Rayleigh that have transmitted in the optical fiber thus.When bending appears in optical fiber, the attenuation of fiber middle light signal will increase, and by the detection of checkout equipment to its attenuation, can determine the degree that optical fiber is bent, and by to the catoptrical processing of Rayleigh, just can further determine the specific address and the character of fault.
The checkout equipment of the utility model Surveillance center can many composite cables of the touring detection of timesharing.Therefore, a center can be under the situation without relaying, and the monitoring radius reaches all objects that need detect in 40Km to the 80Km scope.
The utility model is except that Surveillance center's checkout equipment electricity consumption, and transmission line, senser element must not powered.Passive transmission line and senser element have been exempted Remote Power Supply, also do not have electromagnetic interference problem, and working stability is reliable, and I﹠M is convenient and swift, has prolonged maintenance period, connect and have economized investment and operation and maintenance expenses usefulness, have the good ratio of performance to price.
When the utility model is applied to piping networks such as communication pipe, catch-basin pipeline, sewer line, with optical cable along pipeline laying, and at relevant position setting pressure type senser element, the unlatching of well lid (or stolen), being damaged by pressure of pipeline can both cause the bending of optical fiber in the optical cable by senser element, Surveillance center is by the real-time detection to optical cable, discovery pipeline that just can be instant or well lid unusual by computer software, provides corresponding fault geographic position.Based on the utility model, can set up a comprehensive piping network management system for monitoring that integrates detection, webmaster and document management.The foundation of this system can fundamentally improve the passive situation of safeguarding of present piping network, to underground pipe network one " eyes " has been installed, and the maintenance of pipe network is safeguarded from traditional patrolling and examining become intelligent maintenance.
When the utility model is applied to fire alarm system, adopt memory metal heat sensitive sensor spare or fusible metal heat sensitive sensor spare, optical cable is laid along the object that needs protection.According to the difference of memory metal prescription, can make the 35 ℃ of senser elements that can accurately control to 180 ℃ of temperature; Memory metal type heat sensitive sensor spare also can be made discrete type or continuous type fire alarm device.Continuous type memory metal heat sensitive sensor spare is particularly useful for the monitoring of the high-power service cable in city.
Adopt fusible metal heat sensitive sensor spare, also can change its prescription, make the 60 ℃ of senser elements that can accurately control to 120 ℃ of temperature, cooperate with composite cable, not only can be used for fire alarm, can also directly start fire-fighting, form water smoke or water spray, reach timely fire-fighting and quote the dual purpose of fire address.
