Description
Technical field
The utility model relates to the robotization deformation monitoring field of large-scale structures such as dam, bridge, landslide, particularly needs to lay many features monitoring point on large-scale structures.The gps antenna array acceptor, it can robotization receives be laid in the observation data of unique point gps antenna, thereby effectively reduces the hardware cost of engineering, can realize the safety monitoring of carrying out to structures in conjunction with independently developed aerial array on-line monitoring system.
Background technology
At present, applying GPS (Global Position System) carries out deformation monitoring, mainly contain two kinds of patterns: first kind of pattern is only with several GPS receivers, artificial pointwise image data regularly, obtain distortion between each phase by aftertreatment, the GPS deformation monitoring of this pattern belongs to conventional deformation monitoring pattern, and the GPS deformation monitoring of Yunyang pagoda just belongs to this pattern.The advantage of this pattern is that simple, economy, cost are low, and the GPS receiver can be shared with other engineering.The shortcoming of this pattern is to realize robotization, can not the continuous monitoring distortion.At present, because many production units all are being devoted to simplifying of labour, and such monitoring pattern requires have the labour of some to come image data termly, carry out Data Post but also will spend the regular hour, consequently Guan Jian data often need just can obtain for a long time assessment and analyze, so aut.eq. just seems more and more important.In addition, if, monitoring them in remote place, monitoring site just compares difficulty.Remote, precipitous or have the place on landslide, common monitoring equipment to be difficult to arrange and safeguard, and in most cases they also can only provide regular information.
Second kind of pattern all settled a GPS receiver exactly on each monitoring point, carry out round-the-clock automatic monitoring incessantly.The deformation monitoring example of this pattern has the China crustal deformation monitoring network and every river rock dam automatic monitoring system etc.The advantage of this pattern is to monitor dam deformation automatically and continuously.Compare with the method for observation corner relative geometrical relation in the traditional measurement, the GPS automated monitoring technology has very big advantage.It can realize increasingly automated, alleviates field operation intensity greatly, can obtain a position three-dimensional coordinate rapidly again simultaneously.Rock dam automatic monitoring system is the most successful example every the river, it is the integrated of new and high technologies such as GPS, digital communication, computer network, control automatically, precise engineering survey and modern data processing, provides a kind of new method for dam outward appearance automatic monitoring simultaneously; But it also has weakness in actual applications, and the cost of system is exactly a very big problem.Accurate measurement type GPS receiver price is very high, if adopt traditional GPS monitoring scheme, cost can be geometric series and increase progressively along with the increase of measuring point, setting up a relatively large monitoring system often needs astronomical budget, and this is unaccommodated from economic angle.Though realized the increasingly automated of deformation monitoring every river rock dam outward appearance distortion GPS automatic monitoring system, but also paid sizable cost: total funds have surpassed 6,000,000 yuan, remove software, because each distortion measuring point need be equipped with the GPS receiver, the single-point expense is also more than 200,000 yuan.High like this investment cost has restricted the application of GPS aspect deformation monitoring, prevention and minimizing geologic hazard greatly.Therefore, need to seek the cost that better method reduces and save the GPS deformation monitoring.
As described, above two kinds of methods all can not with the GPS technological perfectionism be applied to the deformation monitoring field, therefore need to seek a kind of better monitoring scheme, to overcome in above-mentioned two kinds of patterns shortcoming separately, bring into play their advantage, make the GPS monitoring give full play to its continuity, real-time, the characteristics of periodicity and robotization.Given this we design the gps antenna array acceptor.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of gps antenna array acceptor that is used for receiving a plurality of gps antenna signals is provided, too high and cycle is carried out the problem that data are not enough and human cost is high that GPS observation obtains observation with the cost that solves the continuous operation monitoring system of GPS robotization, thereby the feasible low-cost high automation disaster monitoring system that sets up becomes possibility.
The utility model solves its technical matters and adopts following technical scheme: the aerial array control circuit board is housed in its housing, and the digital circuit on this circuit board is provided with radio frequency chip IC1, relay circuit, LCD circuit.The GPS-OEM plate also is housed in the described housing, its output terminal is continuous with the GPS-OEM plate place in circuit on the aerial array control circuit board by radio frequency line: the control coding chip IC2 of described digital circuit and RF chip are realized the different gps antennas of glitch-free gating, and the GPS input signal that the GPS-OEM plate is received according to the command interval regular hour from a glitch-free antenna that switches to appointment of antenna, the control circuit that singlechip chip IC3 and peripheral circuit thereof are formed is supported the key entry of peripheral hardware numeric keypad, and IC3 carries out data communication by serial interface chip IC 6 and peripheral hardware PC (PDA) in addition.
The utility model replaces commercial GPS receiver with GPS-OEM (Original Equipment Manufacturer) integrated circuit board, its shared cell can receive each antenna gps signal and is sent in the GPS-OEM plate in addition, and the Rinex form of the standard of generation outputs to peripheral apparatus.A GPS receiver wants 100,000 at least, and the OEM plate only needs several ten thousand yuan, so just can reduce cost.By the single-chip microcomputer 80C51 in the digital circuit, control relay circuit, coding chip, RF chip wherein can not have the gps signal that leaks and disturb the reception different antennae again each other.The serial interface chip makes single-chip microcomputer and peripheral hardware PC carry out data communication, thereby can control entire equipment by software.Such GPS-OEM plate can receive a plurality of antennas, compares with conventional commercial GPS receiver, and an area monitoring system can significantly reduce the number of receiver, can reduce the monitoring cost greatly.Also have, the utility model has been optimized the performance and the compatibility of many days line monitoring systems of GPS on the one hand significantly, required expense when having reduced deformation monitoring widely again on the other hand on the basis of the product of GPS shared device.
In a word, it is compatible good to the utlity model has, and makes and the monitoring low cost and other advantages.
