The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, the symbols 1-7 in the figures are respectively represented as: the device comprises a monitoring platform 1, a bridge pier settlement monitoring device 2, a bridge pier 3, a laser transmitter 4, a laser receiver 5, a data processing device 6 and a power supply device 7.
Example (b): as shown in fig. 1 and 2, the pier settlement automatic monitoring system of the present embodiment includes a monitoring platform 1 and a plurality of pier settlement amount monitoring devices 2. Each bridge pier settlement amount monitoring device 2 is in communication connection with the monitoring platform 1; each pier settlement amount monitoring device 2 is arranged on a plurality of piers 3 respectively. The bridge pier settlement amount monitoring device 2 comprises a laser transmitter 4 and a laser receiver 5. The bridge pier settlement amount monitoring device 2 is used for transmitting the laser transmitter 4 to the laser receiver 5 of other bridge pier settlement amount monitoring devices 2. The laser distance measuring device works according to the laser distance measuring principle between the laser transmitter 4 and the laser receiver 5, the laser receiver 5 is a receiver with a laser reflection device, the transmitter receives the laser echo of the reflector 5, and the distance is measured according to the principle that the distance is = (time x light speed)/2. Laser emitter 4 contains two laser emission devices to have angle regulation's device, the directional laser receiver of opposite pier of manual regulation before the installation, as shown in figure 1, laser emitter 4 simultaneously to laser receiver 4, laser receiver 5 transmission two bundles of laser to detect the relative position between two pier settlement monitoring devices 2, thereby detect the relative settlement between the pier of installing pier settlement monitoring devices 2.
In this embodiment, the bridge pier settlement amount monitoring device 2 includes two laser receivers 5. The bridge pier settlement amount monitoring device 2 is in a strip shape, the laser receiver 5 is arranged at two ends of the bridge pier settlement amount monitoring device 2, and the laser transmitter 4 is arranged in the middle of the bridge pier settlement amount monitoring device 2. In this embodiment, the receiving ranges of the two laser receivers 5 of the bridge pier settlement amount monitoring device 2 face a first direction, and the transmitting range of the laser transmitter 4 of the bridge pier settlement amount monitoring device 2 faces a second direction opposite to the first direction.
The pier settlement amount monitoring device 2 further comprises a data processing device 6, and the data processing device 6 is electrically connected with the laser transmitter 4 and the laser receiver 5. The data processing device 6 is used for processing data obtained by laser measurement, the data processing device 6 comprises a wireless communication module, and the data processing device 6 transmits the detected data to the monitoring platform 1 through the wireless communication module. In this embodiment, the wireless communication module communicates with the monitoring platform 1 via a bluetooth/ZigBee/2G/4G protocol. The pier settlement amount monitoring device 2 further comprises a power supply device 7, and the power supply device 7 is electrically connected with the data processing device 6, the laser transmitter 4 and the laser receiver 5.
In the process of monitoring the settlement of a plurality of piers 3 by using the pier settlement automatic monitoring system of the embodiment, one pier settlement amount monitoring device 2 is arranged on each pier 3 to be monitored. In the arrangement process, the two laser receivers 5 of each bridge pier settlement amount monitoring device 2 need to be arranged in the vertical direction, so that a line segment between the two laser receivers 5 is parallel to the axis of the bridge pier 3.
The bridge pier settlement amount monitoring devices 2 on each bridge pier 3 form a cascade structure, wherein the cascade structure means that the laser transmitter 4 of each front stage bridge pier settlement amount monitoring device 2 transmits laser to the laser receiver 5 of each secondary stage bridge pier settlement amount monitoring device 2 to measure the distance between the front stage laser transmitter 4 and the two secondary stage laser receivers 5L 1 AndL 2 . Since the installation position of the pier settlement amount monitoring device 2 of the preceding stage and the installation position of the pier settlement amount monitoring device 2 of the secondary stage are at known positions of the piers 3, and the distance between the piers 3 is a known amount, the horizontal distance D between the laser transmitter 4 of the preceding stage and the laser receiver 5 of the secondary stage is also a known amount. The relative position index between the pier settlement amount monitoring device 2 at the secondary stage and the pier settlement amount monitoring device 2 at the front stage can be obtained according to the measurement resultdRelative position indexdThe calculation formula of (2) is as follows:
，
wherein L is1And L2The distances between the laser transmitter 4 of the previous stage and the laser receivers 5 of the two secondary stages, respectively; d is the horizontal distance between the laser transmitter 4 of the previous stage and the laser receiver 5 of the next stage.
The change in the vertical position between the secondary pier settlement amount monitoring device 2 and the preceding pier settlement amount monitoring device 2 can be obtained from the historical data of the relative position index d, so that the relative settlement height between the preceding pier 3 and the secondary pier 3 can be obtained. The reason is that when uneven settlement occurs between the pier 3 at the front stage and the pier 3 at the secondary stage, there is a relative vertical position change between the pier settlement amount monitoring device 2 at the front stage and the pier settlement amount monitoring device 2 at the secondary stage, so that the value of the relative position index d changes, and therefore the relative settlement height between the pier 3 at the front stage and the pier 3 at the secondary stage can be obtained from the historical change of the relative position index d.
The pier settlement amount monitoring devices 2 on each pier 3 form a cascade structure, and each pier settlement amount monitoring device 2 can measure the relative settlement between the pier 3 where the pier settlement amount monitoring device is located and the pier 3 on the secondary side, so that the settlement height of each pier 3 can be obtained according to the relative settlement data as long as the actual settlement height of any one pier 3 provided with the pier settlement amount monitoring device 2 is measured.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, the description thereof is not repeated herein.
