Description
Technical field
The utility model belongs to the control technology field, relates to monitoring system, especially relates to a kind of bridge monitoring system based on software bus platform.
Background technology
Bridge at run duration owing to can be subjected to weather, oxidation, corrosion or factor such as aging, and under the effect of dead load or mobile load, suffer damage for a long time, its strength and stiffness can be in time increase and reduce, this has not only influenced safe driving, and shortened the serviceable life of this bridge.Therefore be necessary on the basis of prior art level, the assessment of foundation collection analysis of bridge structure, compunication and network, modern sensor detection, monitoring technology, bridge and maintenance management are one, health monitoring evaluating system based on aspects such as monitoring, state estimation and bridge maintenance management, in order to monitoring and assessment bridge running status, for maintenance management provides foundation.
For every bridge block being implemented the health and safety monitoring, multiple sensors need be set multiple physical quantitys such as the displacement of bridge, strain, vibration acceleration are gathered automatically, then the data of gathering are sent to monitoring center by transmission system and process, handle and analyze.The monitoring method that existing bridge monitoring system adopts mainly also comprises following dual mode except the most traditional measurement, record and the processing of manually carrying out data:
The 1 bridge monitoring mode of utilizing the gsm cellular network to connect.
The bridge monitoring mode that adopts GSM to connect is to utilize the voice channel of GSM to set up point-to-point data transmission channel, controls each Acquisition Instrument image data on the bridge respectively by monitoring center's computing machine.Its course of work is: the long-range GSM data transmission unit of GSM data transmission unit active call that is attached thereto by monitoring center's computer control connects, monitoring center's computing machine is directly controlled the wherein Acquisition Instrument image data that links to each other with long-range GSM data transmission unit subsequently, treats to control another Acquisition Instrument again after its collection finishes.
This kind method, the same set of equipment of data center can only be gathered a bridge block or the sensing data that Acquisition Instrument connects at one time.And also be point-to-point control mode to the device control on the bus, so the speed of data acquisition is slow, complex operation.The method of data transmission is based on mobile network's dedicated channel, and the expense height uses inconvenient.
The 2 bridge monitoring modes of utilizing optical cable to connect.
The bridge monitoring mode of utilizing optical cable to connect, its course of work is: sensor is received Acquisition Instrument by cable, and Acquisition Instrument adopts on-the-spot RS485 bus to be connected on the control terminal machine.The control terminal machine connects photoelectric commutator and inserts long-range fiber cable network.Set up long-range the connection by monitoring center's photoelectric commutator with the monitoring center computing machine again, realize bridge monitoring.The bridge monitoring mode of utilizing optical cable to connect is the main embodiment of the present bridge monitoring system of having set up, this mode is actually to adopt special optical cable or rent the public optical cable of telecommunications and has replaced gsm cellular network in the mode one, and the transmission network in the middle of making is more reliable, transfer rate is higher.But it is still point-to-point collection and control mode, adopts optical network device cost height in addition, and maintenance difficulties is big, and monitoring center's relative fixed is set up relatively difficulty of large-scale monitor network.
Hence one can see that, set up bridge monitoring system according to above-mentioned two kinds of monitoring modes after, all be to adopt special-purpose transmission channel, implement point-to-point collection and control.Therefore, the bridge monitoring system of setting up according to these two kinds of monitoring modes all is single dedicated system, and promptly certain monitoring system is only monitored a certain specific bridge, can't set up large-scale monitor network.In actual life, city or regional traffic system all are made up of other means of transportation such as many bridge blocks, tunnels.The monitoring system of having set up at present all is the single monitoring to every bridge block, tunnel, and each monitoring system has all adopted different networking equipments, monitoring technique and network structure basically, this not only needs great amount of manpower and material resources, very big difficulty is also arranged in the maintenance management, also very unfavorable to the statistical study and the experience exchangement of monitoring situation.
For this reason, people have carried out long-term exploration, various solutions have been proposed, for example, in recent years, proposed a kind of new bridge monitoring method again on engineering theory, the core concept of this method is: the intelligent control unit of each monitoring point inserts GPRS or cdma network by data transmission unit and communication base station, be connected to the Internet, connect monitoring center's computing machine by router again.By this internetwork connection mode, monitoring center's computing machine can be set up data transmission with a plurality of monitoring points simultaneously asynchronously and be connected, and realizes multiple spot monitoring and control.The data processing unit of monitoring center's computing machine adopts the mode of multithreading simultaneously, realizes multitask data acquisition and data processing.For this reason, there is the researcher to invent a kind of bridge monitoring system application number: 200710106918.4, this system comprises the sensor that is installed on the bridge, the Acquisition Instrument that links to each other with described sensor, the intelligent control unit that links to each other with described Acquisition Instrument, and the monitoring center's computing machine that comprises data transmit-receive unit and data processing unit; Described Acquisition Instrument is used to gather coupled sensing data; Described intelligent control unit is controlled described Acquisition Instrument image data and is transmitted corresponding data; Described data transmit-receive unit sends to data processing unit with the data that receive; Described data processing unit carries out concrete operations to the data that described data transmit-receive unit receives.It provides a kind of bridge monitoring system, is used for setting up large-scale monitoring network under bridge distributes scattered situation, realizes bridge monitoring.
Obviously, such scheme if many bridge blocks adopt identical networking equipment and technology, is set up new large-scale monitoring network so under the scattered distribution situation of bridge, and the monitoring that realizes many bridge blocks is feasible; Otherwise can only be feasible in theory.Reason is: if the ascending physical signal interface or the communication protocol difference of the multiple Acquisition Instrument that adopts, it is adaptive adaptive with communication protocol then to require to adopt multiple intelligent control unit and different Acquisition Instrument to carry out physical interface; Equally, the ascending physical signal interface of intelligent control unit is different with communication protocol, require then that data transmission unit is descending to possess different physical interfaces and communication protocol, and the last provisional capital of data transmission unit is the interface and the communication protocol of unified access GPRS or cdma network.In the middle of the reality, it is very difficult needing various data transmission units, and therefore this in this case mode is difficult to carry out, and cost is very high.
This shows, realize that the distributed Centralized Monitoring of loose coupling of entire city or regional a plurality of bridges helps reducing cost, improve monitoring efficiency and ability.Therefore, it is very necessary and urgent it being studied.But based on the different technologies interface of existing different types of rridges monitoring system, directly interconnected or to adopt certain hardware device to realize interconnected, very difficult, cost is very big.
