Abstract
The invention discloses a bridge pier impact force monitoring device. The bridge pier impact force monitoring device comprises a liquid level sensor used for acquiring data of the water level of a river channel, a flow velocity sensor used for acquiring data of the flow velocity of river water, a data acquisition circuit used for acquiring data of the liquid level sensor and data of the flow velocity sensor, and a control circuit used for analyzing and processing the data and having control over an alarm circuit. The bridge pier impact force monitoring device detects impact force of the river water, and gives an alarm when the impact force reaches the limit of the bearing capacity of a bridge, and the situation that because a bridge collapses, lives and properties of people are threatened is avoided.
Description
?
Technical field
The present invention relates to bridge pier bridge condition monitoring device field, particularly, relate to a kind of bridge pier impulsive force monitoring device.
Background technology
bridge is built mostly on river course, and river has very strong impulsive force to bridge pier, and the water level in river course is very large on the impact of bridge.In summer, in every flood season, river water level sharply rises, and river strengthens the impulsive force of bridge pier, and bridge is caused to serious test.Bridge is safe under certain impact power, but water level goes up, water speed is accelerated, and water strengthens the impulsive force of bridge, and bridge very easily collapses, for example, summer in 2010, water level went up suddenly, and current accelerate, make collapsing of Guanghan, Sichuan Shi Tingjiang railway bridge, two joint compartments of K165 train are fallen into the river, and as can be seen here, are very necessary to the monitoring of the impulsive force of bridge.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of bridge pier impulsive force monitoring device, and its impulsive force to river detects, and starts to report to the police while reaching the maximum holding capacity of bridge, avoids bridge collapse to bring lives and properties to threaten to people.
The present invention addresses the above problem adopted technical scheme:
Bridge pier impulsive force monitoring device, comprising:
River water level is carried out to the liquid level sensor of data acquisition;
River flow velocity is carried out to the flow sensor of data acquisition;
The data acquisition circuit that the data of liquid level sensor and flow sensor are gathered;
The control circuit that data are carried out analyzing and processing and warning circuit is controlled.
In the present invention, liquid level sensor, flow sensor are measured the water level of river and flow speed data respectively, and send to after data acquisition circuit is processed and send control circuit to, control circuit carries out Data Management Analysis to the data that collect, excessive to the impulsive force of bridge pier when analyzing river, be greater than the limit that bridge can bear, control alarm device alarm, alarm device is started working, people take measures to limit vehicles or pedestrians on bridge and pass through, and avoid causing damage to people's lives and properties.Because the shape in bridge opening differs, the height that is water level has certain impact to flow velocity, when waterline is constantly raised, some position, bridge opening is higher, and its width is narrower, and flow velocity is had a certain impact, now, water becomes large to the impulsive force of bridge, and control circuit will be according to the shape in bridge opening, according to the data of liquid level sensor and flow sensor and according to certain algorithm, river is calculated the impulsive force of bridge.
As preferably, described level sensing is static pressure type liquid level sensor.Static pressure type liquid level sensor utilizes the measuring principle of hydrostatic pressure, pressure is converted to electric signal, through amplifying circuit, amplify and compensating circuit compensation again, finally with 4～20mA or the output of 0～10mA current system, it can further pass through its accuracy of detection, improves the analysis precision of subsequent control circuit.
As preferably, described flow sensor is electromagnetic type flow sensor.The mode that electromagnetic type flow sensor adopts sensor, input current, prime amplifier, main amplifier, phase detector, wave filter, direct current amplifier to connect successively, and between phase detector and sensor, be connected with square-wave generator and encourage amplifying circuit to do and feed back.The signal that working fluid produces carries out impedance transformation through input amplifier, then has main amplifier to amplify, and because the signal that flow velocity produces is very faint, utilizes the high-amplification-factor of main amplifier, to improve the accuracy of detection to data.
As preferably, described warning circuit is audible and visual alarm circuit.
To sum up, the invention has the beneficial effects as follows:
The present invention utilizes liquid level sensor, flow sensor respectively the water level of river and flow speed data to be measured, control circuit carries out analyzing and processing to data, the impulsive force of river is detected, while reaching the maximum holding capacity of bridge, start to report to the police, avoid bridge collapse to bring lives and properties to threaten to people.
