Furthermore, the time calibration module is a GPS time calibration module, the GPS time calibration module is configured to acquire a calibration time signal through a navigation satellite, and the controller is configured to calibrate a clock of the control unit according to the calibration time signal.
Further, the communication module is a WiFi communication module and/or a GPRS communication module.
Further, the liquid in the communicating vessel is insulating liquid, the communicating vessel is a transparent container, and the color of the liquid in the communicating vessel is different from that of the communicating vessel.
Further, the inside of the communicating vessel is in a vacuum state.
More specifically, the communicating vessel is a U-shaped tube, the communicating vessel is fixed on a road bridge, namely concrete of the road bridge, changes of the road bridge can be detected through the communicating vessel, for example, a change is an inclination, the lengths of the fluid formed at the two ends of the U-shaped tube are different, and the inclination of the road bridge can be compared through detecting the lengths of the fluid. If another change is vibration, the vibration, especially low frequency vibration, is a great hazard to the bridge, and the vibration can cause the length of the liquid in the U-shaped pipe to change dramatically.
The low-frequency vibration is characterized in that one end of the road bridge is lifted, the other end of the road bridge is lowered, and the amplitude of the lifted end relative to the lowered end is basically the same; the other type is elastic vibration, the lifting and lowering amplitudes at the two ends of the road and the bridge are different, or the two ends of the road and the bridge are different in occurrence time, and potential hidden dangers of the vibration are large. In contrast, elastic vibration is a more malignant bridge vibration, which is not easy to observe, and has a greater potential risk, and the damage to the road bridge is huge.
The communicating vessel is internally filled with liquid, when the bridge generates displacement or deformation, the liquid plane in the communicating vessel is always positioned on the same plane, but the length can be changed, particularly the liquid level height is changed. Through a plurality of communicating vessels, the liquid level altitude change at the same moment can distinguish different states of the bridge, such as bridge inclination and bridge vibration, and the liquid level altitude change of different communicating vessels at the same moment can distinguish the property of the bridge vibration, namely
The shape of linker is the U-shaped, also is the U-shaped pipe, and the liquid level height of two pipes changes along with road and bridge's gesture change, and the linker includes two pipes that the bottom links to each other, and the intraductal insulating liquid that has, generally speaking is insulating oil, and after intraductal joining liquid, take out intraductal air through first blow vent 3 and second blow vent 4, and the inside is confined, and liquid can not follow intraductal evaporation. After the vacuum is pumped out, the liquid in the tube can not be subjected to the resistance of air pressure when flowing again, the flow is smoother, and the reaction is more sensitive.
The communicating vessel is provided with a filling opening 5, and after the liquid is consumed, the liquid can be replenished through the filling opening 5, and the communicating vessel can also be used for periodic replacement before the liquid goes bad.
The liquid is necessary to be replaced before the liquid is deteriorated, and the liquid level height detection principle of the liquid is capacitance detection. Specifically, two pairs of electrodes are arranged in the communicating vessel, each pair of electrodes is provided with two polar plates, the two polar plates are arranged in parallel, the polar plate distance is strictly controlled, and therefore the capacitance between the two electrodes is certain under the condition that other conditions are determined. However, in the present embodiment, it is not always necessary that a part of the liquid exists between the electrodes, that is, the insulating medium between the electrodes.
When the liquid level is lower, only a small part between the two electrodes is insulating liquid, and the small part is vacuum; when the liquid level is higher, more parts between the two electrodes are insulating liquid, and less parts are vacuum; obviously, under two conditions, the electric capacity of two electrodes is different, and the controller sends the stable frequency stable rectangular wave signal of amplitude to two polar plates, and under the different capacity condition of two polar plates, the electric current that forms is different, can reflect the electric capacity size between two polar plates through the size of gathering the electric current, can reversely release the height of liquid level in the linker through the size of electric capacity.
The timing module is used for coordinating clocks among a plurality of control units, and a universal and reliable timing module is a GPS timing module, and the principle of the timing module is that a clock signal is obtained from a navigation satellite, data display is provided, and the Beidou time service precision is equal to minus 9 times of second of 10, which is enough to meet the needs of people.
The controller sends the liquid level height signal that the linker was gathered to outside intelligent terminal together with clock signal expert, and outside intelligent terminal receives the signal that a plurality of controllers sent, compares the signal, when discovering potential hidden danger, informs the staff to arrive the on-the-spot verification, takes measures when necessary.
The intelligent terminal is usually a server, and the server receives signals of a plurality of controllers, plots the signals of the plurality of controllers into a graph, and finds the abnormality from the graph.
The controller is usually distributed on the road and bridge as a whole with the communicating vessel.
The controller and the server adopt a point-to-point communication mode, or the controller is point-to-point, and then the controller and the server communicate one to one.
The controller and the server are in a point-to-point communication mode, one mode which can be implemented is that a GPRS communication module is arranged on the controller, the controller is a control panel which takes a single chip microcomputer as a core, the model of the single chip microcomputer is STM32F103C8T6, the model of the GPRS communication module is SIM800A, the controller is connected to the internet through the communication module, and the controller sends acquired signals to the server located on the internet through the communication module.
The point-to-point mode has small time delay and good timeliness, but because the data is transmitted by a telecom operator, each controller is provided with one communication module, and the cost is higher.
In another mode, most controllers are slave computers, communication modules of the slave computers are WiFi communication modules, the slave computers transmit the collected data to the host computers through the WiFi communication modules, the host computers are also provided with GPRS communication modules besides the WiFi communication modules, and the host computers package and send the collected data to servers located on the internet.
This approach requires fewer GPRS modules and is less expensive to operate, but with a slight delay compared to the above-described embodiments.
The communicating vessel is usually a colorless transparent glass tube, while the internal liquid is usually a colored liquid, usually the liquid is the natural color, and the state of the liquid can be known by observing the color of the liquid, such as whether aging occurs or not, and water enters. The two colors are different, and the state of the communicating vessel can be visually observed by naked eyes.
